  By the way, it is preferable that the 1st outer side terminal 31 and the 2nd outer side terminal 41 consist of a metal with high electroconductivity, for example, copper, a copper alloy, etc. Thus, the first outer terminal 31 (second outer terminal 41) and the voltage terminal 53 (current terminal 52) can be reliably conducted. In contrast, the first protective member 32 (second protective member 42) is preferably made of a metal harder than the metal constituting the first outer terminal 31 (second outer terminal 41), such as stainless steel. Thereby, it is possible to reduce the wear of the first protection member 32 (second protection member 42) due to the sliding contact of the first spring body 28 (second spring body 29) (described later).

  On the other hand, the clamping mechanism 20 presses the voltage connection portion 13 from the outside to hold the voltage terminal 53 between the pair of first outer terminals 31 and 31 and presses the current connection portion 12 from the outside. The current terminal 52 is sandwiched between the pair of second outer terminals 41, 41.

The holder 21 has a wide first inner diameter portion 26 corresponding to the voltage connection portion 13 and a narrow second inner diameter portion 27 corresponding to the current connection portion 12. Among these, the first inner diameter portion 26 is provided with a pair of first spring bodies 28 and 28 for sandwiching the voltage connection portion 13 from the outside, and the second inner diameter portion 27 is provided with the current connection portion 12. A pair of second spring bodies 29, 29 that are sandwiched from the outside are provided. The holder 21 is preferably made of an insulating material such as synthetic resin.

  Each first spring body 28 (second spring body 29) is made of a plate spring made of stainless steel or the like with a central portion 28a (29a) protruding inward. Further, both ends 28 b (29 b) of the first spring body 28 (second spring body 29) are respectively mounted in the mounting grooves 21 a of the holder 21. Thereby, when the clamping mechanism 20 moves up, the first protection member 32 (second protection member 42) is pressed inward by the first spring body 28 (second spring body 29). Yes.

  When the clamping mechanism 20 moves from the lower side to the upper side with respect to the connection mechanism 15, the voltage connection unit 13 (current connection unit 12) has a pair of first spring bodies 28, 28 (a pair of second springs). A pair of first outer terminals 31 and 31 (a pair of second outer sides) of the voltage terminal 53 (current terminal 52) and the voltage connection part 13 (current connection part 12) are held between the spring bodies 29 and 29). The terminals 41 and 41) are surely electrically connected.

  Next, the effect | action of this Embodiment which consists of such a structure is demonstrated with reference to Fig.5 (a)-(b).

  First, the drive mechanism 19 is degenerated in advance, and the moving body 30 is lowered. Thereby, the clamping mechanism 20 moves to the standby position (FIG. 5A). Next, an electrical device 50 for performing a performance test is mounted in the opening 14 of the front plate 11 of the apparatus main body 10 (see FIG. 2).

  At this time, each voltage terminal 53 of the electric device 50 is disposed between the pair of first outer terminals 31 and 31 of the corresponding voltage connection portion 13. In this case, each voltage terminal 53 and the pair of first outer terminals 31, 31 are slightly separated from each other, so that each voltage terminal 53 and the pair of first outer terminals 31, 31 are electrically connected to each other. Not connected.

  Similarly, each current terminal 52 of the electric device 50 is disposed between the pair of second outer terminals 41 and 41 of the corresponding current connection portion 12. In this case, since each current terminal 52 and the pair of second outer terminals 41, 41 are slightly separated from each other, the electric current between each current terminal 52 and the pair of second outer terminals 41, 41 is electrical. Not connected to.

  Next, the drive mechanism 19 is extended and the moving body 30 is raised. Thereby, the clamping mechanism 20 rises and moves to the engagement position (FIG. 5B). At this time, the holder 21 of the clamping mechanism 20, the pair of first spring bodies 28, 28, and the pair of second spring bodies 29, 29 rise together with the connection mechanism 15.

  During this time, each first spring body 28 is guided by the first inclined portion 33 of the first protection member 32, and then rises while sliding on the outer surface 32 b of the first protection member 32. In this case, each first spring member 28 is pressed inward by each first protection member 32. In addition, when the first protective member 32 is pressed inward, the first outer terminals 31 are also pressed inward. As a result, the voltage terminal 53 and the pair of first outer terminals 31, 31 of the voltage connection portion 13 are electrically connected.

  Similarly, each second spring body 29 is guided by the second inclined portion 43 of the second protection member 42, and then rises while sliding on the flat surface 42 a of the second protection member 42. In this case, each second spring member 29 is pressed inward by each second protection member 42. Further, when the second protective member 42 is pressed inward, the second outer terminals 41 are also pressed inward. As a result, the current terminal 52 and the pair of second outer terminals 41, 41 of the current connection portion 12 are electrically connected.

  By the way, as described above, the pair of first spring bodies 28, 28 are provided in the wide first inner diameter portion 26 of the holder 21, and the pair of second spring bodies 29, 29 are the narrow first of the holder 21. 2 provided in the inner diameter portion 27. Therefore, both the voltage connection part 13 and the current connection part 12 can be pressed from the outside only by performing the ascending operation of the clamping mechanism 20, and the voltage terminal 53 and the current terminal 52 are respectively connected to the first outer terminal 31 and It can be clamped by the second outer terminal 41. Moreover, since the first spring body 28 is not engaged with the current connection portion 12 when the clamping mechanism 20 is raised or lowered, the operation of the clamping mechanism 20 can be performed smoothly.

  In this way, the electrical device 50 and the power source side of the test apparatus (not shown) are connected via the connection device 100. After that, the electric device 50 is subjected to a performance test by causing a current to flow from the test device to the electric device 50 via the voltage connection unit 13 and the current connection unit 12.

  After the performance test of the electric device 50 is completed, the drive mechanism 19 is degenerated again. Thereby, the moving body 30 moves downward, and the clamping mechanism 20 is returned to the standby position.

  Next, the electric device 50 is removed from the apparatus main body 10. Thereafter, another electrical device 50 for performing the performance test is mounted on the apparatus main body 10 (that is, the electrical device 50 is replaced) in the same manner as described above, and the performance test is performed.

  Thus, according to the present embodiment, the connection mechanism 15 is pressed from the outside by the clamping mechanism 20 that is movable in the vertical direction, and the voltage terminals (upper connection terminals) 53 of the electric device 50 are paired with the first outer sides. While sandwiched between the terminals 31, 31, the current terminal (lower connection terminal) 52 is sandwiched between the pair of second outer terminals 41, 41. Accordingly, the pair of connection terminals 53 and 52 of the electric device 50 and the outer terminals 31 and 41 of the connection parts 12 and 13 are connected using only one drive mechanism 19 and one clamping mechanism 20. Can do. Therefore, the wiring device 100 can be made compact, and the structure and control contents of the wiring device 100 can be simplified.

  Further, according to the present embodiment, the first spring body 28 (second spring body 29) is composed of a leaf spring from which the central portion 28a (29a) protrudes. The first protection member 32 (second protection member 42) can be evenly pressed by the two spring bodies 29).

  In addition, according to the present embodiment, the first protection member 32 (second protection member 42) has the first spring body 28 (second spring body 29) when the clamping mechanism 20 moves relative to the connection mechanism 15. ) And a first inclined portion 33 (second inclined portion 43) in sliding contact. Accordingly, the first spring body 28 (second spring body 29) that has risen is smoothly guided onto the outer surface 32b of the first protection member 32 (the flat surface 42a of the second protection member 42).

  Further, according to the present embodiment, the first protective member 32 includes the inner surface 32a that contacts the first outer terminal 31, the outer surface 32b that contacts the first spring body 28, the inner surface 32a, and the outer surface 32b. And a connecting portion 32c for connecting the two. Thus, the width of the voltage connection portion 13 can be increased according to the width of the first inner diameter portion 26. Therefore, the clamping mechanism 20 can be raised smoothly without engaging the current connection portion 12.

  Moreover, according to this Embodiment, the 1st protection member 32 (2nd protection member 42) consists of a metal harder than the metal which comprises the 1st outer side terminal 31 (2nd outer side terminal 41). Accordingly, even when the first spring body 28 (second spring body 29) is in sliding contact with the first protection member 32 (second protection member 42) many times, the first protection member 32 (second protection member 32). The member 42) is less likely to wear. On the other hand, since the first protective member 32 (second protective member 42) and the first outer terminal 31 (second outer terminal 41) do not slidably contact each other, the first outer terminal 31 (second outer terminal 41). There is no risk of wear.

  In the present embodiment, the pair of connection terminals 53 and 52 of the electric device 50 are arranged in the vertical direction, and the clamping mechanism 20 moves in the vertical direction with respect to the connection mechanism 15. However, the present invention is not limited to this, and the pair of connection terminals of the electrical device may be arranged in the left-right direction, and the clamping mechanism may be moved in the left-right direction with respect to the connection mechanism.
