An insulating substrate, which extends toward the inner side of the casing and has a slider in the radial direction, is provided in the casing in parallel in the lengthwise direction, and the slider contacts rotatably on the inner peripheral surface. And a plurality of ring-shaped electrodes that are formed into a multipolar connector.

[Action]

The cable direction can be set in any direction by making the insulating substrate rotatable with respect to the casing of either or both of the plug connector that constitutes the multi-pole connector and the jack connector that is detachably connected. Therefore, there is no constraint based on the cable direction in the device or device design.

〔Example〕

Hereinafter, the multi-pole connector of the present invention will be described in detail with reference to the drawings based on embodiments based on the gist of the configuration. Note that the same parts are denoted by the same reference numerals throughout the drawings.

FIG. 1 is a schematic perspective view showing a main part of an embodiment of the multipolar connector of the present invention in a see-through state. Explaining the plug connector 16 with reference to FIG. 1, an insulating substrate 24 is provided inside the casing 22 so as to be rotatable only in a rotating direction indicated by an arrow. A front view of the plug connector 16 is shown in FIG.

On the insulating substrate 24, pin contacts 10 that are a plurality of connectors facing the opened outside of the casing 22 are arranged at predetermined positions, and the pin contacts 10 extend toward the inside of the casing 22. And its tip is connected to the slider 20 bent in the radial direction.

In the casing 22, a plurality of ring-shaped electrodes 18 are provided in parallel in the length direction, and the connection cable 2 which is the external connection means 21 is provided so as to extend in the direction orthogonal to the back side of the casing 22. The conductor and the ring-shaped electrode 18 are electrically connected to each other.

Pin contact 10 extending inward of casing 22
Are set to predetermined lengths, respectively, so that the inner peripheral surface of a predetermined corresponding ring-shaped electrode 18 and the slider 20 can slide in contact with each other.

When the plug connector 16 having the above-mentioned configuration is connected to the conventional jack connector 7 shown in FIG.
