Description

  The present invention relates to a connector including a first connection member and a second connection member that are electrically connected to each other.

  Conventionally, a connector including a plurality of pin contacts, an insulator, an FPC, an elastic backing, and a conductive thin film is known (see Patent Document 1 below).

  The pin contact is made of a metal having no elasticity, and has a substantially plate-like main body and a pin portion connected to the main body. The pin contacts are arranged at equal intervals on the mounting surface of the substrate. The pin portion of the pin contact protrudes at right angles to the mounting surface of the substrate.

  The insulator is disposed on the body of the pin contact. A through hole is formed in the insulator, and a pin portion of a pin contact is inserted into the through hole, and a tip portion of the pin portion protrudes from the upper surface of the insulator.

  A plurality of through holes are formed in the FPC and the elastic backing so as to correspond to the pin portions of the plurality of pin contacts arranged on the substrate. The outer diameter of the pin portion of the pin contact is smaller than the diameter of the through hole of the FPC and larger than the diameter of the through hole of the elastic body.

  The FPC is disposed on the top surface of the insulator on the substrate. The FPC has a conductive pattern.

  The elastic backing is attached to the surface of the FPC opposite to the insulator facing surface.

  The conductive thin film is formed in an elastic body-lined through hole. The conductive thin film is connected to the conductive pattern of the FPC. A plurality of pin contacts and an insulator constitute a first connecting member, and an FPC, an elastic backing and a conductive thin film constitute a second connecting member.

When the pin portion of the pin contact of the first connection member is inserted into the through hole of the elastic body lining through the through hole of the FPC of the second connection member, the through hole is elastically expanded outward in the radial direction. The conductive thin film of the backing through-hole is elastically pressed against the outer peripheral surface of the pin portion of the pin contact by the elastic force (elastic restoring force) of the elastic backing, so that both connecting members are conducted.

As a result, a sufficient contact force is not generated between the conductive thin film on the inner peripheral surface of the through hole and the outer peripheral surface of the pin portion, and there is a possibility that a contact failure may occur.

  Also, when the pin part of the pin contact is inserted into the through hole of the elastic body through the through hole of the FPC, the conductive thin film on the inner peripheral surface of the through hole cannot follow the elastic deformation of the peripheral part of the through hole, and the conductive There was a risk of damage to the thin film.

  Next, a method for connecting the first contact member 3 and the second contact member 7 of this connector will be described.

  FIG. 1 is a cross-sectional view showing a state before the connector is connected, while FIG. 8 is a cross-sectional view showing a state after the connector is connected.

  As shown in FIG. 1, first, the hole 5 a of the elastic sheet 5 of the first connection member 3 is positioned in the columnar conductor 8 of the second connection member 7.

  Next, the first connecting member 3 is lowered, and the columnar conductor 8 of the second connecting member 7 is relatively inserted into the hole 5a of the elastic sheet 5 and the hole 6a of the regulating plate 6.

  Since the slit 4a is formed in the pad portion 42a of the conductor pattern 42, the columnar conductor 8 is press-fitted while pushing the conductor contact piece portion 4b of the flexible substrate 4 of the first connecting member 3 into the hole 5a of the elastic sheet 5. . The tip 8 a of the columnar conductor 8 passes through the hole 5 a of the elastic sheet 5 and reaches the hole 6 a of the regulation plate 6. At this time, the rear end portion 8b of the columnar conductor 8 is press-fitted into the hole 5a of the elastic sheet 5 and elastically expands the diameter of the hole 5a. Therefore, as shown in FIG. Force), the conductor contact piece 4b of the flexible substrate 4 is elastically pressed against the outer peripheral surface of the rear end 8b of the columnar conductor 8. In this way, the first connection member 3 and the second connection member 7 are connected, and the electrical module that is one connection object and the printed circuit board that is the other connection object are electrically connected.

  When the columnar conductor 8 of the second connection member 7 is inserted into the hole 5 a of the first connection member 3, the deformation in the thickness direction DT5 of the elastic sheet 5 of the first connection member 3 is suppressed by the restriction plate 6. The Furthermore, the diameter of the front end portion 8a of the columnar conductor 8 is larger than the diameter of the rear end portion 8b, and the hole 5a greatly expands when the front end portion 8a of the columnar conductor 8 passes through the hole 5a of the elastic sheet 5, and then Since contraction is caused by a large radial elastic force (elastic restoring force) accumulated by the expansion, deformation of the elastic sheet 5 in the thickness direction DT5 is suppressed. Therefore, a predetermined elastic deformation force (elastic return force) in the radial direction can be generated in the hole 5 a, and the conductor contact piece 4 b of the flexible substrate 4 can reliably contact the outer peripheral surface of the columnar conductor 8.

  As described above, according to the first embodiment, the conductor contact piece 4b of the flexible substrate 4 more reliably contacts the outer peripheral surface of the columnar conductor 8, so that the first connection member 3 and the second connection member 7 are in contact with each other. A reliable and stable contact with is ensured.

  Further, the pad portion 42a of the conductor pattern 42 is formed on the insulating film 41 having extremely low stretchability, and when the columnar conductor 8 is inserted into the hole 5a of the elastic sheet 5, the conductor contact piece 4b becomes the hole 5a of the elastic sheet 5. Even if the hole 5a is pushed and deformed, the insulating film 41 does not expand and contract, so that the conductor pattern 5 is not damaged.

  Further, when the columnar conductor 8 is inserted into the hole 5a of the elastic sheet 5, the conductor contact piece 4b is rubbed by the columnar conductor 8, and the wiping function of the columnar conductor 8 works, so that dust adhered to the conductor contact piece 4b, etc. Is removed.

  Further, since the diameter of the front end portion 8a of the columnar conductor 8 is larger than the diameter of the rear end portion 8b, once the columnar conductor 8 is inserted into the hole 5a of the elastic sheet 5, the columnar conductor 8 can be easily removed from the hole 5a. The contact state between the first contact member 3 and the second contact member 7 is maintained.
