Description

  The present invention relates to a connector having a contact portion that is elastically connected to a mating contact portion of a mating connector.

  Usually, a connector is made by fixing a contact to an insulator injection-molded with a resin material. In this case, the contact is fixed in the pitch direction of the insulator.

  Further, as a conventional connector, there is a connector in which a leaf spring and a flexible wiring board are stacked. The leaf spring and the flexible wiring board are connected in the pitch direction even near the contact portion. In this connector, in particular, a positioning portion in the pitch direction is manufactured with high accuracy so that a pitch shift does not occur.

Japanese Patent No. 2774394

  However, in the conventional connector, it is difficult for the contacts fixed in the pitch direction of the insulator to be equal to or smaller than the pitch determined by the thickness of the insulator by molding.

  Moreover, since the connector of patent document 1 is a structure in which the leaf | plate spring and the flexible wiring board were connected to the pitch direction also near the contact part, there is almost no ability to absorb the variation in the dimension of each contact part, and contact reliability is good. There is a problem that it is low.

  In addition, the connector of Patent Document 1 must be manufactured with a high precision in the positioning portion in the pitch direction so that a pitch shift does not occur. There is a problem that it is difficult to make it.

  Furthermore, since the connector of patent document 1 increases the number of contacts per unit area, it is difficult to increase the contact force in consideration of stress.

The present invention provides a connector to be connected to a mating connector, a plate-like substrate having elasticity and having a plurality of openings formed in a predetermined pitch direction, an insulating layer disposed on at least one surface of the substrate, A plurality of contact portions formed on the insulating layer and between the openings of the base material , and each of the contact portions has inclined portions formed on both side portions on the opening side. The inclined portion is most preferably a connector in which a conductor portion that is connected to the counterpart contact portion when the contact portion and the counterpart contact portion are arranged and connected in a staggered manner is provided. Features.

  According to the connector of the present invention, since a part of the conductor portion is a contact portion that contacts the mating connector, an injection molded insulator can be dispensed with, and a narrow pitch can be achieved.

  Moreover, a conductor part can be provided in the both sides of a contact part, and while making narrow pitch, it can enable high contact force setting.

  In addition, since the pitch of the contact portion is determined not by injection molding but by pressing, the pitch can be reduced and the connector can be densified.

  Further, since the base material is punched at a predetermined pitch, each contact portion can be independently elastically deformed, and has a high ability to absorb the dimensional variation of each contact portion, thereby improving connection reliability.

  In addition, the contact portion constitutes a conductor portion insulated from each other on both sides in the pitch direction of the connector, enters between adjacent contact portions of the mating connector at the time of fitting, and the conductor portions provided on both sides come into contact with each other to electrically Therefore, it is possible to connect at half the pitch and to increase the density.

  Furthermore, since the base material is connected at least at one end in the pitch direction of the contact portion, the contact force on both sides of the contact portion is inclined by a predetermined angle in the opposite direction, and the pitch direction component is canceled out. The contact force can be increased without applying excessive stress to the surface.

The connector of the present invention is a connector that is connected to a mating connector, has a plate-like base material having elasticity and having a plurality of openings formed in a predetermined pitch direction, and an insulating layer disposed on at least one surface of the base material.
