FIG. 1 is a schematic diagram of a conductor connection structure according to an embodiment of the present invention. Please refer to FIG. 1 . In this embodiment, the conductor connection structure 100 includes at least one first conductor C1 , at least one second conductor C2 , a first bridge 110 , a second bridge 120 , a first pressure plate 130 , and a second pressure plate. 140. The locking accessory 160 (a screw in this embodiment) and the double-layer toothed washer 150. The first bridge 110 has a first conductive part 112 , and the second bridge 120 has a second conductive part 122 . The first conductor C1 and the second conductor C2 are both clamped between the first bridge 110 and the second bridge 120 , and the first conductor C1 and the second conductor C2 maintain a space SP. Here, the space SP is essentially formed by the first conductor C1, the second conductor C2, the first bridge 110 and the second bridge 120 forming a stacked structure.

Furthermore, as shown in FIG. 1 , the first conductive portion 112 is structured to contact the first conductor C1 and the second conductor C2 to electrically conduct between the first conductor C1 and the second conductor C2. The second conductive portion 122 is in contact with the first conductor C1 and the second conductor C2. It is electrically connected between the first conductor C1 and the second conductor C2. In this way, the first conductor C1 and the second conductor C2 can achieve electrical conduction with each other through the first conductive part 112 or the second conductive part 122 .

In addition, this embodiment also provides additional stacking components, that is, the first pressure plate 130 structure is abutted on the side of the first bridge 110 facing away from the first conductive part 112, and the second pressure plate 140 structure is abutted on The side of the second bridge 120 facing away from the second conductive portion 122 . At the same time, the locking part 160 is locked to the first pressure plate 130, the first bridge part 110, the second bridge part 120 and the second pressure plate 140, and the locking part 160 passes through the first pressure plate 130, the first bridge part 110, and the second pressure plate 140 in sequence. The space SP, the second bridge 120 and the second pressure plate 140 are provided to achieve the effect of locking these stacked components.

More importantly, in this embodiment, the double-layer toothed washer 150 is sleeved on the locking accessory 160 and the structure is in contact between the locking accessory 160 and the first pressure plate 130 . Accordingly, the double-layered tooth type washer 150 exerts the lifting tension generated between the double-layered meshing teeth between the first pressure plate 130 (or the second pressure plate 140) and the locking accessory 160 to provide a more direct response to thermal expansion and contraction. The anti-loosening force is precisely because the double-layer toothed washer 150 does not have structural contact with the first conductor C1 or the second conductor C2, so it can effectively avoid the aforementioned structural damage to the first conductor C1 or the second conductor C2. situation occurs. Different from the conventional method that only uses friction to prevent loosening, in this case, the lifting tension of the double-layer meshing teeth of the double-layer tooth type washer 150 is used to press the first pressure plate 130 (or the second pressure plate 140) With the lock attachment 160, it directly resists the force of loosening to achieve a direct anti-loosening effect. The double-layer tooth type washer 150 will be further explained later.

In this embodiment, the first bridge member 110 is embedded with the first conductive portion 112 The second bridge member 120 is formed on the insulating plate body 111 , and the second conductive part 122 is embedded in the insulating plate body 121 . Therefore, the first conductor C1 and the second conductor C2 of this embodiment are substantially located on the same plane, so that the first conductor C1 is completed by being contacted and clamped by the structure of the first conductive part 112 and the second conductive part 122 electrical connection with the second conductor C2.

As shown in Figure 1, the double-layered tooth type washer 150 includes a first component 151 and a second component 152 that mesh with each other in a tooth structure. The opposite surfaces of the first component 151 respectively have a first tooth row 151a and a meshing tooth row. 151b, the two opposite surfaces of the second component 152 respectively have a second tooth row 152a and a meshing tooth row 152b, wherein the meshing tooth rows 151b and 152b can mesh with each other, thereby improving the locking force of the locking component 160, and also due to the shows an intermeshing tooth structure, which can effectively avoid loosening. The meshing tooth depth D1 of the double-layer tooth type washer 150 is larger than the first conductor C1, the second conductor C2, the first bridge 110, the second The sum of the thermal expansion amounts of the bridge member 120 , the first pressure plate 130 and the second pressure plate 140 along the locking direction of the locking member 160 . In other words, the double-layer toothed washer 150 of this embodiment needs to be selected according to the relevant stacking structure (ie, the first conductor C1, the second conductor C2, the first bridge member 110, the second bridge member 120, the Corresponding measures are taken according to the thermal expansion of the first pressure plate 130 and the second pressure plate 140 to ensure that the conductor connection structure 100 remains tight and avoids loosening.

On the other hand, as shown in the partial enlargement of FIG. 1 , the first tooth row 151a of the first component 151 is in contact with the locking member 160 , and the second tooth row 152a of the second component 152 is in contact with the first pressure plate 130 . And the double-layered toothed washers 150 are respectively in contact with the locking member 160 and the first pressing plate 130 (or the first pressing plate 130) through the first tooth row 151a and the second tooth row 152a. The friction force at the second pressure plate 140) is greater than the friction force between the meshing teeth 151b and 152b, so that the lifting tension between the double-layer meshing teeth is applied to the first pressure plate 130 (or the second pressure plate 140) and the locking member. 160, the anti-loosening force under thermal expansion and cold contraction is improved to avoid loosening, and therefore the double-layer toothed washer 150 will not be in direct structural contact with the first conductor C1, the second conductor C2 or the third conductor used for power transmission. The first conductive part 112 and the second conductive part 122 can therefore be regarded as differentiating the structural strength and power transmission functions of the conductor connection structure 100 into different parts without affecting each other. In addition, the first pressure plate 130 and the second pressure plate 140 of this embodiment can be made of metal to improve the tolerance to the double-layer toothed washer 150 .

Figure 2 is a busbar using a conductor connection structure. FIG. 3 is a detailed schematic diagram of the conductor connection structure of FIG. 2 . Please refer to FIG. 2 and FIG. 3 at the same time. In this embodiment, the conductor connection structure 200 is used to connect two bus bars 300 and 400 together. The first conductor C1 in the aforementioned embodiment is equivalent to the bus in this embodiment. The first conductor 310 of the row 300, and the second conductor C2 of the aforementioned embodiment is equivalent to the second conductor 410 of the bus 400 of this embodiment, that is, the conductor structure used to transmit power in the bus 300, 400.

Furthermore, as shown in FIG. 3 , the difference from the previous embodiment is that the number of the first conductor 310 and the number of the second conductor 410 in this embodiment is multiple (four is used as an example in this embodiment, but it is not taken as an example). (Limited), therefore, in addition to the same components as the previous embodiment, the conductor connection structure 200 of this embodiment also needs to include a plurality of third bridges 170 to be clamped between the two adjacent first conductors 310 and is clamped between two adjacent second conductors 410 . Here, the third bridge 170 includes an insulating plate body 171 and an For the third conductive parts 172 and 173, the third conductive parts 172 and 173 are respectively located on two opposite surfaces of the insulating plate body 171, and the structures of each third conductive part 172 and 173 are in contact with the corresponding first conductor 310 and the third conductor 310. The two conductors 410 are electrically connected between the first conductor 310 and the second conductor 410 corresponding to each other.

FIG. 4 is a partial schematic diagram of the interior of the conductor connecting structure of FIG. 1 . Please refer to Figure 1 and Figure 4 at the same time. In this embodiment, the inclination angle θ1 of the meshing tooth rows 151b and 152b relative to the first pressure plate 130 or the second pressure plate 140 is greater than the thread angle θ2 of the locking accessory 160, so that the double-layer The toothed washer 150 can effectively prevent the lock accessory 160 from loosening. In addition, in order to allow the first tooth row 151a to smoothly engage the locking accessory 160, and to allow the first tooth row 152a to smoothly engage the first pressure plate 130, the hardness of the double-layered tooth type washer 150 in this embodiment is greater than the hardness of the locking accessory 160 and the first pressure plate 130 The hardness is to maintain the tight state of the relevant components after the locking is completed. In this embodiment, the material of the double-layer toothed washer 150 is high carbon steel, the material of the first pressure plate 130 and the second pressure plate 140 is medium carbon steel, and the material of the locking accessory 160 is medium carbon steel, so that the double-layer toothed washer 150 is made of medium carbon steel. The tooth row of the layered tooth type washer 150 can bite into the first pressure plate 130 or the second pressure plate 140, and after the bite, it can not be damaged during the tightening process of the locking accessory 160. Looking back at the existing locking process, since the conductors are mostly made of copper or aluminum (in order to ensure their conductivity), they will be damaged during the locking process and cannot maintain the bite state and easily become loose.

Figure 5 shows the first component of Figure 4 from another perspective. Please refer to Figure 1, Figure 4 and Figure 5 at the same time. As described above about the thermal expansion of related components, for the double-layer toothed washer 150, it is necessary to make the first conductor C1, the second conductor C2, and the first bridge The member 110, the second bridge member 120, the first pressure plate 130 and the second pressure plate 140 are locked along the The total amount of thermal expansion in the locking direction of 160 shall not exceed the distance raised by the rotation angle δ of the single tooth of the meshing tooth row 151b when the locking accessory 160 is rotated as shown in Figure 5, in order to maintain the optimal anti-loosening of the double-layer tooth type washer 150 Effect. On the other hand, as long as the sum of the above-mentioned thermal expansion amounts to cause the locking part 160 to loosen and rotate is smaller than the above-mentioned rotation angle δ, it can be driven by the tooth profile of the meshing tooth rows 151b and 152b of the double-layer tooth profile washer 150. The lock attachment 160 is reset.

FIG. 6 is a schematic diagram of a conductor connection structure according to another embodiment of the present invention. Please refer to Figure 6 and compare with Figure 3 or Figure 1. Different from the previous embodiment in which the locking accessory 160 is located between the conductors, the locking accessory 160 in this embodiment is located between the first conductor 310, the second conductor 410, the first conductor 310 and the second conductor 410. The periphery of the bridge member 110, the second bridge member 120 and the third bridge member 170 is still locked to the first pressure plate 130 and the second pressure plate 140, so as to communicate with the third pressure plate inside through the first pressure plate 130 and the second pressure plate 140. The first conductor 310, the second conductor 410, the first bridge 110, the second bridge 120 and the third bridge 170 provide a pressing effect, thereby achieving the same effect as the previous embodiment. It can be seen from this that with the different connection methods of conductors, the conductor connection structure of the present invention can produce corresponding connection methods, which will be further explained later.

FIG. 7 is a schematic diagram of a conductor connection structure according to another embodiment of the present invention. Please refer to Figure 7 and compare with Figure 1.

Another double-layer tooth type washer 150. It should be mentioned here that the threads of the locking parts 161 and 162 are adapted to each other, and similar to that shown in FIG. 4 , for the double-layered tooth type washer 150 of this embodiment, the meshing tooth rows 151b, The inclination angle θ1 of 152b is greater than the thread angle θ2 of the locking parts 161 and 162, and the remaining identical components or structures will not be described again.

FIG. 8 is a schematic diagram of a conductor connection structure according to another embodiment of the present invention. Please refer to FIG. 8 and compare it with FIG. 1. The difference from the previous embodiment is that this embodiment adopts a method in which the first conductor C1 and the second conductor C2 are partially overlapped with each other and directly electrically connected. However, the same as the previous embodiment in that , this embodiment still uses the locking member 160 to be locked on the first pressure plate 130 and the second pressure plate 140 to clamp the first conductor C1 and the second conductor C2 between the first pressure plate 130 and the second pressure plate 140 . Since the first pressure plate 130 and the second pressure plate 140 are made of metal to increase their pressing capacity and tolerance, this embodiment also includes insulating plate bodies 111 and 121, where the insulating plate body 111 is structurally abutted against the first pressure plate. 130 and the first conductor C1, the insulating plate body 121 is structurally in contact with the second pressure plate 140 and the second conductor C2 to avoid electrical short circuit.

Figure 9 is a schematic diagram of a conductor connection structure according to another embodiment of the present invention. Please refer to Figure 9. As mentioned above, the conductor connection structure can change according to the configuration of the bus bar. Therefore, in this embodiment, the bus bars 300 and 400 are connected to the first conductor 310 and the second conductor 310 on the same side through the conductor connection structure 200A. The conductors 410 are connected, and the relevant components can be known from Figures 1 to 7, so they will not be described again.

FIG. 10 is a schematic diagram of a conductor connection structure according to another embodiment of the present invention. Please refer to FIG. 10 , where the components with the same symbols as those in the previous embodiment can be known from the previous description, and therefore will not be described again. What is different from the previous embodiment is that, in addition to the same insulating plate body and conductive portion as mentioned above, the first bridge member 210 and the second bridge member 220 of this embodiment also have flange structures 213 and 223 respectively protruding from the The first pressure plate 130, the second The side of the pressure plate 140 restrains the first pressure plate 130 , the second pressure plate 140 , the first conductor 310 and the second conductor 410 to stop and prevent the first pressure plate 130 and the second pressure plate 140 from rotating relative to the double-layer teeth. Shape Washer 150 is used to achieve the anti-loosening effect.

To sum up, in the above embodiments of the present invention, after the first conductor and the second conductor for transmitting power form a stacked structure through the first bridge member, the second bridge member, the first pressure plate and the second pressure plate, The aforementioned components are then locked together with screws and double-layered toothed washers, wherein the double-layered toothed washers are sleeved on the screws and abutted between the first pressure plate and the screws. In this way, the first conductor and the second conductor clamped between the first bridge member and the second bridge member are conductive in addition to the first conductive portion of the first bridge member and the second conductive portion of the second bridge member. In addition to the electrical connection between them, they can also be firmly clamped due to the above-mentioned stacking structure and the locking ability of the corresponding screws.

Wherein, when there are multiple first conductors and second conductors respectively, a third bridge piece is used to be clamped between any two adjacent first conductors or between any two adjacent second conductors. between the conductors, and the third conductive part is used to provide electrical connection between the conductors. Furthermore, the double-layered toothed washers can respond to the thermal expansion of each component of the aforementioned stacked structure, so that the meshing tooth depth of the double-layered toothed washer is greater than the sum of the thermal expansions of the aforementioned stacked structure, thereby ensuring conductor connection. The structure will not loosen.

In addition, no matter the above-mentioned single conductor or multiple conductors, the double-layer toothed washer is in contact between the screw and the first pressure plate, thereby effectively avoiding direct contact with the first conductor or the second conductor, so it can Avoid causing surface damage to the first conductor and the second conductor. In the present invention, the toothed washer is in contact with the screw and the pressure plate to form an anti-loosening structure, rather than directly in contact with the conductor. Therefore, the lock accessories (screws) and pressure plate can be selected with appropriate hardness. The combination of double-layered toothed washers allows the toothed washers to firmly bite into the surface of the screws and pressure plate. The bite marks will not be damaged or slip when the screws are locked, achieving the best anti-loosening effect. In other words, unlike the existing washers that use the reaction force when being compressed to increase friction to prevent loosening, the present invention uses the lifting tension of the double-layer meshing teeth of the double-tooth type washers to apply to the pressure plate and the locking accessory. As a force to directly resist loosening, it is a more direct way to prevent loosening. In this way, it can not only provide a stable and durable locking mechanism, but also achieve the original power transmission function.
