Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called two-piece connector, which is a pair of electrical connectors, and more particularly to a connector characterized by supporting means for conductive contacts held in an insulating holder in a cantilever shape.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 52-12141 discloses an elastic deformable portion having a raised contact portion at its tip, a conductive contact having a contact portion and a fixed portion, and the fixed portion is integrally inserted into an insulating holder. There is disclosed a two-piece connector in which the conductive contact is held in a cantilever shape. In this connector, when the connectors are fitted to each other, the contact portions of the conductive contacts are in sliding contact with the contact surfaces of the elastic deformable portions of the conductive contacts, and when the fitting is completed, the contact portions of the mutual contacts are completed. Is elastically pressed into contact with the contact portion.

[0003]

However, in the connector provided with the conductive contact as in the known connector, the contact contact portion is an extremely important portion where the contact portion of the mating contact is elastically pressed. Nevertheless, it is not directly supported by the insulation carrier, i.e. merely extends from it. Therefore, the contact contact portion is deformed when the conductive contact is incorporated in the insulating holder or is deformed over time due to the pressure contact force of the contact portion, and it is difficult to achieve a given contact with the contact portion. Contact reliability may not be obtained.

It is an object of the present invention to overcome the drawbacks of the prior art by making a creation on the insulating holder.

[0005]

SUMMARY OF THE INVENTION The present invention comprises an elastically deformable portion having a contact portion, an elongated conductive contact in which a contact portion and a fixed portion are sequentially located from one end to the other end, and an insulating holder. A pair of connectors that can be combined with each other and are held in a cantilever shape by fixing the conductive contact to the insulating holder at the fixing portion, wherein the contact portion of one of the connectors is the other of the It is premised on a two-piece connector that elastically comes into pressure contact with the contact contact portion of the connector.

A feature of the present invention is that, in the above-mentioned premise, the insulation holder has a conductive contact support surface area formed by a part of the insulation holder over a range substantially equal to the length of the contact portion. While the conductive contact support surface region abuts the non-contact surface side of the contact contact portion to support the contact contact portion, the contact contact portion is
The point is that it is floated from the insulation holder and released .

[0007]

In the present invention having the above-mentioned structure, when the pair of connectors are combined, the contact portions of the pair of conductive contacts move while sliding relative to each other to get over each other,
Furthermore, it moves while sliding relatively along the contact surface of the mating conductive contact, and along with this movement, the elastic deformable portion warps and displaces toward the back side against the elastic force. Finally,
Each of the contact portions rides on the contact contact portion of the mating conductive contact and elastically press-contacts with each other to achieve electrical connection.
