【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the universal joint for electrical connection of the present invention is a combination of a socket A and a plug B. The socket A is attached to one end of the housing 1 in the front-rear direction X. Has a through hole 2 formed through the through hole 2 and an insertion hole 3 formed at the other end in the left-right direction Y. Inside the through hole 2 and the through hole 3, a spring contact 11 is arranged. Further, the spring contactor 11 arranged in the insertion hole 3 is arranged so that the sliding stroke gap 4 is left in the insertion hole 3.

In the plug B, a through hole 6 is formed in the front-rear direction X of the housing 5, a spring contact 11 is arranged in the through hole 6, and further, the housing 5 has A cylindrical contact portion 7 that can be inserted into the through hole 2 and the insertion hole 3 of the socket A is formed at one end.

The housings 1, 5 constituting the socket A and the plug B, the spring contact element 11, and the tubular contact portion 7 are each formed of an electric conductor, and are in a good connection state. It is configured to be obtained.

Then, the spring contact 11 arranged in the through holes 2 and 6 and the insertion hole 3 of the socket A and the plug B is provided in the through holes 2 and 6 and the insertion hole 3. As shown in FIGS. 3 and 4, the recessed portion 9 is fitted in the recessed portion 9, and the ring piece 12a and the ring piece 12b are arranged in parallel with each other at a predetermined interval, and the ring pieces are arranged in parallel with each other. A plurality of spring pieces 13 are arranged between the ring pieces 12a and 12b, and a spring contact 11 is fixed and fixed in the recess 9 at the outer edge of the ring pieces 12a and 12b. The projection-shaped leg portion 8 is formed for the purpose.

Further, as shown in FIGS. 5 and 6, the spring piece 13 is arranged at a predetermined angle with respect to the ring pieces 12a and 12b arranged in parallel. The one side 14 is formed so as to contact one mating side and the other side 15 contacts the other mating side, and the connection state of the socket A and the plug B and the connection terminal of the device is maintained in good condition. Is what you can do.

Next, the operation will be described based on the above configuration. As shown in FIG. 1, the universal joint for electrical connection of the present invention is a combination of a socket A and a plug B, and a cylindrical contact portion 7 of the plug B is inserted into an insertion hole 3 formed in the socket A. However, since the sliding stroke gap 4 is formed in the insertion hole 3, it is within the range of the axial length of the cylindrical contact portion 7. The socket A and the plug B can be expanded and contracted (arrow X in the figure), and the through holes 2 and 6 formed in the socket A and the plug B can be changed. In this case, the connection position can be changed within the range of the axial length of the connection terminal of the device inserted into the through holes 2 and 6.

Further, in the through holes 2 and 6 and the insertion hole 3, a ring-shaped spring contactor 11 is arranged, and further, the spring pieces 13 constituting the spring contactor 11 are arranged in parallel. Since the ring piece 12a and the ring piece 12b are arranged at a predetermined angle, one side 14 of the ring piece 12a and the ring piece 12b is inserted into the through holes 2 and 6 of the socket A and the plug B and the insertion hole 3, respectively. Since the other side 15 is formed so as to resiliently contact the cylindrical contact portion 7 of the plug B and the connection terminal of the device (FIG. 6), the socket A and the connection terminal of the plug B and the device are connected. It is possible to maintain a good connection state.

Then, the cylindrical contact portion 7 and the connection terminal of the device, which are inserted into the through holes 2 and 6 and the insertion hole 3, are resiliently elasticated by the spring piece 13 of the ring-shaped spring contactor 11. Since it is connected and elastically held at the same time, the cylindrical contact portion 7 and the connection terminal of the device are rotatable (arrow R in the figure), and the socket A and the plug described above are connected. Due to the interaction with B that can be expanded and contracted, it is possible to absorb the height difference between the connection terminals of the devices to be connected, the left and right displacement, or the change in the connection distance.

Then, as shown in FIG. 7, two sets of the universal joints for electrical connection formed as described above are prepared, and they are connected by the connecting rods 10, whereby the range of the axial length of the connecting rods 10 is determined. Since it can be expanded and contracted inside (arrow Y in the figure), it is possible to absorb the height difference between the connection terminals of the devices to be connected, and the above universal joints for electrical connection are both expandable and contractible (arrow X in the figure). Since the respective universal joints for electrical connection are rotatable with respect to the connecting rod 10 (arrow S in the figure), it is possible to absorb the left and right displacement between the connecting terminals and the change in the connecting distance.

FIG. 8 shows an example of the use of the two sets of universal joints for electrical connection connected by the connecting rods 10, in which the batteries 20 are connected to each other. Differences, left and right shifts, and further, changes in the distance between the batteries 20 can be absorbed freely, and each part of the universal joint for electrical connection is connected by a ring-shaped spring contact 11. Therefore, the connection state of the socket A and the plug B and the connection terminal of the device can be maintained in a good state, and a stable connection state can be obtained even when the batteries 20 are connected to each other in which a large current flows.

Furthermore, by changing the combination of the universal joints for electrical connection in various ways, the height difference between the connection terminals of the devices to be connected, the left / right deviation, or the change in the connection distance can be more finely tuned. Since it does not require any skillful work such as soldering when forming the above universal joint for electrical connection, it is stable even when a large current is applied. It is possible to form a universal joint for electrical connection with high quality and high reliability.

In the present embodiment, a cylindrical shaft is used as the connecting rod 10 used when the universal joints for electrical connection are combined, but a bolt and nut may be used. In this case, the connecting rod 10 can be surely prevented from falling off, so that the device can be connected more safely.
