  However, in the case of the conventional slider-type connector 1 described above, as shown in FIG. 11A, the insertion direction into the cable housing portion 9 is arranged on the proximal end side of the flexible conductor 7 supported by the cable connection slider 5. When a tensile load in the orthogonal direction (the direction of arrow B in the figure) is applied, the reinforcing plate 19 is warped, and the contact between the flexible conductor 7 and the terminal portion 13a may become unstable.

  Further, as indicated by an arrow C in FIG. 11B, peeling occurs when the flexible conductor 7 is peeled off from the reinforcing plate 19, and as a result, handling property when the flexible conductor 7 is inserted into and removed from the cable housing portion 9 may be deteriorated. There was also.

  Accordingly, an object of the present invention is to solve the above-mentioned problems, and on the proximal end side of the flexible conductor fixed to the cable housing portion of the slider-type connector, a tensile load in a direction perpendicular to the insertion direction into the cable housing portion. The cable connection can prevent the electrical connection between the flexible conductor and the connection terminal from becoming unstable even if the action is applied, and also prevent the flexible conductor from being peeled off from the cable holding piece by the action of the tensile load. It is to provide a slider.

The above-described object of the present invention is achieved by the following configuration.
(1) The cable holding piece inserted into the cable housing portion of the housing body of the slider-type connector is connected to the housing body so that the cable holding piece can slide in the insertion / removal direction with respect to the cable housing portion.

  According to the configuration of (2) above, the flexible conductor adhered to the lower surface of the cable pressing piece can be accurately and easily positioned on the cable pressing piece by aligning the mounting hole with the positioning protrusion. Assembling workability of the flexible conductor is improved.

  According to the configuration of (3) above, since the cable gripping member is integrally formed with the slider connector, the number of parts is not increased. Also, with the other end of the cable gripping member removed from the locking part on the other side of the cable presser piece, attach the flexible conductor to the lower surface of the cable presser piece, and then connect the other end of the cable gripping member to the cable presser. By locking to the other side surface of the piece, the flexible conductor can be easily sandwiched, and the assembly workability of the flexible conductor is improved.

  According to the cable connection slider of the present invention, the distal end portion of the flat flexible conductor pressed and connected to the connection terminal in the cable housing portion by the cable holding piece is attached to the cable holding piece and the cable holding member holds the cable. It is clamped and fixed to the base end of the presser piece.

  Therefore, even if a tensile load in the direction perpendicular to the insertion direction to the cable housing portion acts on the base end side of the flexible conductor, the tensile load is supported by the holding portion of the cable gripping member and is attached to the cable presser piece. It does not act as a force in the direction of peeling off the flexible conductor.

  Therefore, it is possible to prevent the flexible conductor from being peeled off from the cable pressing piece by the action of the tensile load.

  Also, the base end of the cable holding piece equipped with the cable gripping member is located outside the housing body, and it is easy to ensure strength by increasing the thickness, etc., so the direction orthogonal to the insertion direction to the cable housing part Even if the tensile load is applied, it is possible to avoid the occurrence of warpage due to the tensile load, and it is also possible to avoid the unstable electrical connection between the flexible conductor and the connection terminal due to the warpage.
