Abstract

A connector terminal includes a front contact-point portion that wipes off foreign material by slidingly contacting a plug terminal and a rear contact-point portion that is conductively connected with the plug terminal. The front contact-point portion has a sliding edge that slidingly contacts the plug terminal. The rear contact-point portion includes a contact edge that is thinner than the sliding edge, has a sliding width that is less than that of the sliding edge, and is conductively connected with the plug terminal by passing a sliding path of the sliding edge. Therefore, it becomes less likely for the contact edge to contact foreign material adhered to a portion other than portions at the sliding path. Thus, conduction failure can be prevented. In addition, by providing the connector terminal, it is possible to provide a socket that can similarly prevent conduction failure caused by foreign material.

First claim

What is claimed is:

1. An electric connector comprising:
a connector terminal including
a contact portion that is conductively connected with a mating connector terminal of a mating connector and
an elastic portion that elastically supports the contact portion,
the mating connector terminal serving as a connection object,
the contact portion being formed of a metallic plate,
the contact portion including
a front contact-point portion and a rear contact-point portion at a plate edge portion of the contact portion,
the front contact-point portion and the rear contact-point portion being mutually independent of each other and successively contacting a planar terminal surface of the mating connector terminal in a fitting direction,
wherein the front contact-point portion is provided with a sliding, the sliding edge wiping off foreign material adhered to the terminal surface by slidingly contacting the mating connector terminal up to a contact position where the electric connector and the mating connector are in a fitted state from when the sliding edge contacts the terminal surface of the mating connector terminal, and
wherein the rear contact-point portion is provided with a triangular thin-walled portion and a contact edge of the rear contact-point portion is thinner than the front contact-point portion and
a sliding width of the rear contact-point portion is narrower than that of the sliding edge of the front contact-point portion, the contact edge being formed of a plate edge of the metallic plate, and
the contact edge being conductively connected with the mating connector terminal at a sliding path at the terminal surface where the foreign material has been wiped off by the sliding edge of the front contact-point portion thereby to provide a stable conductive connection.

2. The electric connector according to claim 1 , wherein a plate-thickness center of the contact edge is substantially aligned with a plate-thickness center of the sliding edge.

3. The electric connector according to claim 1 , wherein the connector terminal includes a front terminal and a rear terminal that are integrated to each other, the front terminal including an elastic portion and a contact portion provided with the front contact-point portion, the rear terminal including an elastic portion and a contact portion provided with the rear contact-point portion.

4. The electric connector according to claim 1 , wherein the connector terminal includes the elastic portion and the contact portion including the front contact-point portion and the rear contact-point portion, wherein the front contact-point portion and the rear contact-point portion are integrated to each other.

5. The electric connector according to claim 1 , wherein the thin-walled portion is a terminal portion that protrudes from the elastic portion towards the mating connector terminal.

6. The electric connector according to claim 1 , wherein the thin-walled portion is a terminal portion formed by crushing the metallic plate so as to become thinner than the elastic portion.
