In the figure, 10 is a housing of the connector according to the present invention, 50 is a printed circuit board, 20 is a contact body, 40 is an actuator, and 30 is a member to be connected.

As the member to be connected, for example, as shown in FIG. 2, there is a member in which a plurality of conductors 31 are provided in parallel on the surface of a flexible insulating base 32. At this time, the conductor is formed by applying carbon in a linear manner, for example.

One terminal end of this member to be connected is inserted through the opening of a cavity 11 provided in the housing into the gap between the contact body in the cavity and the inner peripheral surface of the cavity.

Although the other end of the member to be connected is not shown, it is connected to, for example, an electrode of a display to be connected. The connection method is as known in the art: ``The conductor at the end of the base is applied to the electrode at the end of the display, and the conductor is wrapped so as to wrap the edge of the end inside. Secure with clips.

The contact body accommodates its contact portion in the cavity of the housing, and extends from the peripheral wall 1 of the housing so that its terminal end extends outside the cavity.
Penetrate 2. Note that there are a plurality of connecting bodies, and they are arranged in accordance with the spacing between the respective conductors of the members to be connected.

The shape of the contact body is as shown in Fig. 3, with a conductive rubber contact 23 protruding from one side of the contact part and a cam protrusion 2 on the other side.
form 4. The terminal end of the contact body is formed to match the through hole provided in the object to which the connector of the present invention is attached, for example, a printed circuit board.

Another embodiment of the rubber contact is shown in FIG. Figure 4A
In this case, a coating layer 23' of conductive rubber is provided on the contact portion of the contact body. In addition, FIGS. 4B and 4C show rubber contacts as connecting rods 23" that connect the contact parts of a plurality of contact bodies. In FIG. 4B, conductive parts 23"& and non-conductive parts are shown. 23'b is adjusted to the spacing between the contact bodies, and in Fig. 4C, the pitch is narrower than the width of the contact bodies so that the conductive portion is always located on the contact body regardless of the spacing between the contact bodies. It is necessary to come into contact with.

Next, the actuator 40 is inserted into the gap between the cam protrusion side of the contact body in the cavity of the housing and the inner peripheral surface of the cavity. In this actuator, the cam surface 41 comes into contact with the cam protrusion 24 of the contact body, and by pushing this into the cavity,
The contact body is biased and electrically connected to the conductor 31 of the member to be connected using the conductive rubber contact 23.
