First, the structure of the wiring duct 100 will be described in detail again.

As shown in FIG. 12, the wiring duct 100 is a long tubular member having a cross section perpendicular to the longitudinal direction X and formed into a "ㄇ" shape with a lip, and has a top wall 101 and two from the top wall 101. A pair of side walls 102 extending at the side ends and a bottom wall 103 extending from the front ends of the side walls 102 to form a flange portion. As the bottom of the flange The gap between the walls 103 is an opening 104 that communicates the inside and the outside of the wiring duct 100. The wiring duct 100 is disposed such that the opening 104 faces downward, and constitutes a groove-shaped core 105 having a width longer than the opening 104.

On the inner surface of the side wall 102, a conductor holding portion 106 is protruded toward the inner side, and the conductor 110 is fixed to the front end portion of the conductor holding portion 106. The conductor 110 is disposed along the longitudinal direction X of the wiring duct 100, and the elongated rectangular flat connecting surface 111 extending in a straight line shape is exposed inside the core 105. The connection faces 111 of the pair of conductors 110 are disposed at the same height so that the cores 105 face each other.

The contact 2 is electrically connected to each of the quick-connecting terminal portions 4 in a one-to-one manner. In a state where the insertion portion 1 is inserted into the core 105 of the wiring duct 100, the two contact members 2 are elastically contacted to the corresponding conductors 110 at two locations, respectively. Thereby, the contact 2 and the conductor 110 are electrically connected in a one-to-one relationship.

Hereinafter, each configuration of the wiring duct connecting device will be described more specifically.

In the insertion portion 1 of the connecting device main body 9, a partition wall 6 for preventing the paired contacts 2 from coming into contact with each other is formed along the longitudinal direction X. Further, between the partition wall 6 located at the center portion in the width direction Y and the two contact members 2 adjacent thereto, an elastic body 7 that contacts the contact member 2 and applies an outward force is disposed.

Further, the contact portions 32 and 33 on the side of the quick-connect terminal portion 4 and the contact 2 are pushed against the pressure in the thickness direction Z to electrically connect the contact 2 and the quick-connect terminal portion 4. For example, when the contact terminal 2 is fixed in a state where the contact member 2 is fixed, the spring portion 5 (see FIG. 2) is pressed upward in the thickness direction Z, and the terminal portion 4 side and the contact 2 side are fastened. The contact portions 32 and 33 are pushed against each other in accordance with the pressure in the thickness direction Z.

Further, in the wiring duct connecting device of the fifth embodiment, the first elastic body 7A and the second elastic body 7B are collectively composed of the conductive member 60, and the electrical connection structure is formed by the contact portion of the first elastic body 7A. 61 is pressed against the contact structure on the first contact 2A by the elastic force of the first elastic body 7A, and the other contact portion 62 of the second elastic body 7B is pushed against the elastic force of the second elastic body 7B. The contact structure on the second contact 2B is constructed.

Thereby, the first elastic body 7A and the second elastic body 7B (in the fifth embodiment, the spring plate members that integrate the two elastic bodies 7A, 7B) can be used to connect the first contact 2A and the second contact 2B. Pushing together to the outside and electrically connecting the two contacts 2A, 2B. Therefore, the assembly property of the wiring conduit connecting device is improved, and the number of parts is also reduced.

The present invention has been described above based on the embodiments shown in the drawings, but the embodiments are merely examples of the invention, and the invention is not limited by the embodiments. That is, as long as it is within the scope of the present invention, it is possible to carry out appropriate design changes or combinations or replacements of the configurations of the respective embodiments in the respective embodiments.
