Abstract

A connector includes a pushing member having a projection, and a contact made of a conductive material and having a projection accommodating portion of recess shape into which the projection is to be inserted, the projection having a protruding portion that is situated in a lateral surface of the projection with protruding from the lateral surface of the projection and approaches an inner surface of the projection accommodating portion when the projection is inserted into the projection accommodating portion, and a gap forming portion that is situated in the lateral surface of the projection around the protruding portion and forms a predetermined gap between the gap forming portion and the inner surface of the projection accommodating portion when the projection is inserted into the projection accommodating portion, the predetermined gap being wider than a distance between the protruding portion and the inner surface of the projection accommodating portion.

First claim

What is claimed is:

1 . A connector adapted to be connected to a flexible conductor, the connector comprising:
a pushing member having a projection; and a contact made of a conductive material and having a projection accommodating portion of recess shape into which the projection is to be inserted, wherein the projection includes: a protruding portion that is situated in a lateral surface of the projection with protruding from the lateral surface of the projection and approaches an inner surface of the projection accommodating portion when the projection is inserted into the projection accommodating portion; and a gap forming portion that is situated in the lateral surface of the projection around the protruding portion and forms a predetermined gap between the gap forming portion and the inner surface of the projection accommodating portion when the projection is inserted into the projection accommodating portion, the predetermined gap being wider than a distance between the protruding portion and the inner surface of the projection accommodating portion, and wherein when the projection of the pushing member is inserted in the projection accommodating portion of the contact together with the flexible conductor with the flexible conductor being sandwiched between the projection and the projection accommodating portion of the contact such that the projection of the pushing member is covered by the flexible conductor, the protruding portion of the projection presses the flexible conductor against the inner surface of the projection accommodating portion to contact the flexible conductor to the inner surface of the projection accommodating portion, and a redundant portion of the flexible conductor generated upon being inserted into the projection accommodating portion is received in the predetermined gap.

2 . The connector according to claim 1 ,
wherein a dimension of the distance formed between the protruding portion and the inner surface of the projection accommodating portion when the projection is inserted in the projection accommodating portion is smaller than a thickness dimension of the flexible conductor.

3 . The connector according to claim 1 ,
wherein the projection is in a shape of a cylindrical column having a central axis and includes a plurality of the protruding portions arranged at equal intervals in a circumferential direction of the projection and a plurality of the gap forming portions each formed between every adjacent two of the plurality of the protruding portions.

4 . The connector according to claim 3 ,
wherein the projection has four protruding portions as the plurality of the protruding portions and four gap forming portions as the plurality of the gap forming portions.

5 . The connector according to claim 4 ,
wherein the inner surface of the projection accommodating portion of the contact has a shape of a cylindrical tube, and wherein the projection accommodating portion has an inside diameter smaller than a value obtained by adding a double of a thickness of the flexible conductor to a length between two of the four protruding portions of the projection protruding in opposite directions from each other.

6 . The connector according to claim 3 ,
wherein the protruding portion has a shape linearly extending in parallel with the central axis.

7 . The connector according to claim 3 ,
wherein the protruding portion has a spherical shape.

8 . The connector according to claim 1 ,
wherein the pushing member comprises a base member having a plurality of the projections, and wherein the plurality of the projections are separately inserted into the projection accommodating portions of a plurality of the contacts with a plurality of the flexible conductors being sandwiched therebetween.

9 . The connector according to claim 8 ,
wherein each of the plurality of the contacts has a tubular portion and a contact-side flange formed at one end of the tubular portion, wherein the connector further includes a housing having a plurality of contact through-holes through which the tubular portions of the plurality of the contact pass, each of the plurality of contact through-holes being smaller than the contact-side flange of each of the contacts, and wherein when the housing is fixed to the base member such that the tubular portions of the plurality of the contacts pass through the plurality of contact through-holes and the contact-side flanges of the plurality of the contacts are pressed against the base member, the plurality of the contacts are fixed to the base member.

10 . The connector according to claim 9 ,
wherein the base member has a housing fixing post projecting higher than the plurality of the projections, wherein the housing has a post accommodating portion of recess shape, and wherein the housing fixing post is accommodated in the post accommodating portion to fix the housing to the base member.

11 . The connector according to claim 9 ,
wherein the housing is made of an insulating material.

12 . The connector according to claim 9 ,
wherein the housing has a counter connector accommodating portion for accommodating a part of a counter connector.

13 . The connector according to claim 8 ,
wherein the base member is made of an insulating material.

14 . The connector according to claim 1 ,
wherein the pushing member has a pushing member-side flange joined to a root portion of the projection.

15 . The connector according to claim 1 ,
wherein the flexible conductor is disposed to be exposed on a top surface of an insulating substrate body, and wherein the flexible conductor is disposed between the pushing member and the contact such that the flexible conductor faces the projection accommodating portion of the contact and a bottom surface of the insulating substrate body faces the projection of the pushing member.

16 . The connector according to claim 1 ,
wherein the flexible conductor is independently disposed between the pushing member and the contact.

17 . The connector according to claim 1 ,
wherein a pointed portion for piercing the flexible conductor is formed at a tip of the projection.

18 . The connector according to claim 1 ,
wherein the contact is a plug-type contact.

19 . The connector according to claim 1 ,
wherein the contact is a receptacle-type contact.
