Description

  The present invention relates to a connector connected to a mating connector.

  As a conventional technique, there is a connector in which a plurality of conductive engaging members are held in a line through a blank space having a predetermined width between adjacent engaging members.

  In this connector, both connectors are engaged so that the two are opposed to each other and the zipper opening / closing bracket is closed.

  The plurality of engaging members are integrally held by an insulating holding member that is insert-molded with an elastic material (see, for example, Patent Document 1).

JP-A-6-333648

  In the connector of the cited document 1, since the arrangement of the engaging members and the pitch of the conductors coincide with each other, it is difficult to arrange them at a small pitch.

  In addition, the connector has a problem that it has few contacts (one point) and has low reliability.

  In addition, the connector requires a configuration of a zipper opening / closing metal fitting, and there is a problem that the manufacturing cost is high and the fitting operability is poor.

  Further, the mating connector needs to have the conductor configuration in the reverse direction.

  Therefore, the subject of this invention is providing the connector which can form a conductor part and can comprise a pitch small.

  Another object of the present invention is to provide a connector with high reliability in connection.

  Another object of the present invention is to provide a connector that does not require a separate part such as a zipper opening / closing metal fitting.

  The present invention provides a connector to be connected to a mating connector, having a conductor portion and an elastic member provided with the conductor portion and having elasticity, and the elastic member has at least one concave portion and a convex portion, The main feature is that the conductor portion is a connector characterized in that the conductor portion extends and is disposed so as to straddle the concave portion and the convex portion in a direction in which the convex portion is elastically deformed.

  In the connector of the present invention, the plurality of convex portions are arranged, and the conductor portions are arranged at a predetermined pitch perpendicular to the direction in which the convex portions are arranged. It can be made small.

  In addition, since there are a plurality of convex portions, a multi-point connection results in a connector with high connection reliability.

  Moreover, since the convex part is compressed and connected in the arrangement direction of the protrusions, a separate part such as a zipper opening / closing metal fitting is not necessary.

  Moreover, since the same connector as the connector can be used, the cost can be reduced.

  Further, since the connector has a configuration in which the conductor portion is in contact with two or more surfaces, the contact reliability is improved.

  Further, the connector is provided with a plurality of concave portions and convex portions, so that the contact surface is further increased, so that the reliability is improved.

  The connector of the present invention is a connector connected to a mating connector, and has a conductor portion and an elastic member provided with the conductor portion and having elasticity, and the elastic member has at least one concave portion and convex portion. And the said conductor part was implement | achieved by extending and arrange | positioning so that the said convex part might straddle the said recessed part and the said convex part in the direction which elastically deforms.
