Abstract

A connector includes: a first connector including a fitting portion and a first terminal provided in the fitting portion; and a second connector including a fitted portion configured to be fitted into the fitting portion of the first connector and a second terminal that is provided on the fitted portion, extends along a fitting direction, and comes into electrical contact with the first terminal in a case where the fitted portion is fitted into the fitting portion of the first connector, in which in the second terminal, a wide-width portion is formed in the second terminal, and the first terminal comes into contact with the wide-width portion of the second terminal from a state in which the fitted portion of the second connector is started to be fitted into the fitting portion of the first connector to a state in which the fitted portion cannot be fitted any further.

First claim

What is claimed is:

1. A connector, comprising:
a first connector including a fitting portion and a plurality of first terminals provided in the fitting portion, each of the first terminals including a first contacting portion being elastically deformable; and
a second connector including a fitted portion configured to be fitted into the fitting portion of the first connector, and a plurality of second terminals that is provided on the fitted portion, extends along a fitting direction, and each of the plurality of second terminals comes into electrical contact with the first contacting portion of each of the first terminal in a case in which the fitted portion is fitted into the fitting portion of the first connector, wherein:
in each of the second terminals, a wide-width portion, having a dimension in one direction that is larger than a dimension of a general portion, is formed at a distal end side of the fitted portion, the one direction being an in-plane direction of a surface of the second terminal with which the first terminal comes into contact and being orthogonal to the fitting direction of the fitted portion, wherein the general portion is located at a proximal end side and the wide width portion is located at the distal end side whereby the second terminal is wider at the distal end side than at the proximal end side such that a width of the general portion is reduced in order to increase impedance of the second terminal, and
each of the first terminals comes into contact with the wide-width portions of the second terminals with the first contacting portion being elastically deformable from a state in which the fitted portion of the second connector starts to be fitted into the fitting portion of the first connector to a state in which the fitted portion is not able to be fitted any further.

2. The connector according to claim 1 , wherein:
in the first terminal, an inclined guide portion is provided, which is inclined in a direction away from the second terminal on progression toward the second connector from a first terminal contact portion in the fitting direction, the first terminal contact portion being a portion with which the second terminal comes into contact, and
in a state in which the fitted portion of the second connector is not able to be fitted into the fitting portion of the first connector any further, at least a portion of the inclined guide portion is disposed at a position corresponding to the general portion of the second terminal when viewed in a direction perpendicular to the surface of the second terminal with which the first terminal comes into contact.

3. The connector according to claim 1 , wherein an inclined portion, which smoothly connects the wide-width portion and the general portion to each other when viewed in the direction perpendicular to the surface of the second terminal with which the first terminal comes into contact, is provided between the wide-width portion and the general portion in the second terminal.

4. The connector according to claim 1 , wherein the general portion of the second terminal has a substantially constant dimension in the one direction that is the in-plane direction of the surface of the second terminal with which the first terminal comes into contact and that is orthogonal to the fitting direction of the fitted portion.

5. The connector according to claim 1 , wherein the second terminal is formed by using a plate having a thickness direction in a direction perpendicular to the surface of the second terminal with which the first terminal comes into contact.
