  In this way, through the contact structure in which the contacts are pressed against each other, the two contacts 2A and 2B can be stably electrically connected without being affected by the position and posture of the first contact 2A and the second contact 2B. Can be made. Moreover, by using such a contact structure, the assemblability of the wiring duct connecting device is improved and the number of parts is also reduced.

  Furthermore, in the wiring duct connection device of the fourth and fifth embodiments, a plurality of convex contact portions 20 that are continuous in the longitudinal direction X are provided on the outer end of the first contact 2A and the outer end of the second contact 2B. It is integrally formed.

  Thereby, both the first and second contacts 2A and 2B pressed outward are electrically connected to the conductor 110 of the wiring duct 100 through the contact portions 20 formed at the outer end. Therefore, the contact area with respect to the conductor 110 increases, and the contact resistance is suppressed. Moreover, since it contacts in several places, the attitude | position which contacts with respect to the conductor 110 of each contactor 2A, 2B is stabilized.

  Furthermore, in the wiring duct connecting apparatus according to the fifth embodiment, the first elastic body 7A and the second elastic body 7B are both composed of the conductive member 60, and the electrical connection structure is a contact portion of the first elastic body 7A. 61 is pressed against the first contact 2A by the elastic force of the first elastic body 7A, and another contact portion 62 of the second elastic body 7B is used as the elastic force of the second elastic body 7B. And a contact structure pressed against the second contact 2B.

  Accordingly, the first contactor 2A and the second elastic body 7A and the second elastic body 7B (the spring plate member in which both elastic bodies 7A and 7B are integrated in the fifth embodiment) are used. The two contacts 2B can be pressed outward and the two contacts 2A, 2B can be electrically connected. Therefore, the assemblability of the wiring duct connecting device is improved and the number of parts is also reduced.

  As mentioned above, although this invention was demonstrated based on embodiment shown to an accompanying drawing, each embodiment is only what was shown as an example of this invention and this invention is not necessarily limited to these embodiment. That is, within the range intended by the present invention, it is possible to make an appropriate design change in each embodiment, and to combine and replace the configurations of each embodiment.
