Description

[Detailed description of the invention] This invention aims to make a conductor connecting device that connects a main conductor and a sub-conductor connected to power transmission and distribution cables, etc. compact and inexpensive, and easy to assemble. purpose.

Generally, a conductor connecting device for connecting a main conductor and a sub-conductor connected to a power transmission/distribution cable or the like is configured as shown in FIG. 1, for example. In the figure, 1 is a cylindrical main conductor made of copper connected to a power transmission/distribution cable, etc., and 2 is a flat plate-shaped main conductor made of copper arranged below the main conductor 1 and connected to a power transmission/distribution cable etc. The sub-conductor 3 is a contact surface formed by flatly cutting out the right side of the front end of the main conductor 1, and 4 is a contact surface whose upper end is in contact with the contact surface 3 and is fixed to the contact surface 3 by four bolts 5. The copper plate 6 is a three-piece copper plate, in which the convex curved portions 6a and 6b formed at the upper and lower ends thereof are in contact with the left side of the lower end of the copper plate 4 and the left side of the upper end of the sub-conductor 2, respectively. The contact body 7 is a convex curved portion 7 formed at the upper end and the lower end, respectively.
a, 7b are the right side of the lower end of the copper plate 4 and the sub conductor 2
Three right contact bodies, 8 disposed at positions facing each left contact body 6 and in contact with the right side of the upper end;
are three springs whose ends are respectively locked to the central part of each left contact body 6 and to the central part of each right contact body 7, and bias each left contact body 6 and each right contact body 7 inward. is pressed against the copper plate 4 and the sub-conductor 2,
Both conductors 1 and 2 are connected by the copper plate 4 and each contact body 6 and 7.
is connected.

However, in this case, since both conductors 1 and 2 are connected via the copper plate 4 by each contact body 6 and 7,
In addition to the contact bodies 6 and 7, the copper plate 4 is required, and the contact surface 3 must be processed, making it large and expensive, and it is not easy to assemble.

This invention was made with the above points in mind, and consists of a cylindrical main conductor and a flat sub-conductor, each with a concave curved portion at one end abutting both sides of the circumferential surface of the main conductor. Left and right contact bodies are disposed such that the convex curved portion of the other end is in contact with both sides of the end of the sub-conductor, and both sides of the contact bodies are engaged with substantially the center of the two contact bodies. The present invention provides a conductor connecting device including a spring that is biased inward to press the conductors together.

Therefore, according to the conductor connecting device of this invention, the left and right contact bodies having concave curved parts and convex curved parts at both ends are brought into pressure contact with the main conductor and the sub conductor to connect both said conductors. This eliminates the need to use a copper plate or the like as in the past, and also eliminates the need to process the contact surface of the main conductor.
It can be made small and inexpensive, and can be easily assembled.

Next, this invention will be explained in detail with reference to FIG. 2 showing one embodiment thereof.

In the figure, 9 is a cylindrical main conductor made of copper fixed to the bushing 10 and connected to the power distribution cable, and 11 is a flat plate made of copper arranged below the main conductor 9 and connected to the power distribution cable. A sub-conductor 12 includes a base 12a through which the main conductor 9 is inserted through a hole provided in the upper end, and an extension 1 integrally formed with the base 12a extending forward at the center of the lower end of the base 12a.
2b is an L-shaped mounting body, 13 is a mounting body 12
The sub conductor 11 is attached to the lower surface of the extending portion 12b of
A stop body 14 stops the sub-conductor 11 at a predetermined position by contact with the stop body 14, which is an inverted U-shaped cutout formed vertically in the center, through which both conductors 9 and 11 are inserted, and the upper end of the cutout. 15 is an extension body integrally formed with the upper end of the guide body 14; 17 is a support bolt inserted through the extension body 15 and screwed onto the front end of the main conductor 9; and 17, a concave curved portion 17a at the upper end abuts the left side of the peripheral surface of the main conductor 9, and a convex curved portion 17b at the lower end Three left contact bodies 18 are placed in contact with the left side of the upper end of the sub conductor 11 and are disposed between the base 12 a and the guide body 14 . Three right contact members 19 are arranged in positions facing each left contact member 17, with the convex curved portion 18b of the lower end abutting the right side of the upper end of the sub conductor 11, and 19 is a main conductor. 9, between the left and right contact bodies 17 and 18, between the left and right contact bodies 17 and 18 on the rear side and the base 12a, and between the left and right contact bodies 17 and 18 on the front side and the guide body 14.
Four annular spacers 20 are provided between the guide plates 14 on both sides of the upper end of the notch, the outer sides of the concave curves of the contact bodies 17 and 18, and the base 12a of the nuts. 21 to connect each contact body 17, 18 and mounting body 12 to the guide plate 14.
22 and 23 are left and right grooves formed on the outside of the center of each left contact body 17 and each right contact body 18, respectively, and 24 is three springs. , both ends of which are locked in each left groove 22 and each right groove 23, and each contact body 17, 18
is urged inward to press against both conductors 9 and 11, and both conductors 9 and 11 are connected by respective contact bodies 17 and 18.

Therefore, according to the embodiment, the concave curved portions 17a, 18a and the convex curved portions 17b, 18b are provided at both ends.
The left and right contact bodies 17 and 18 having the
By connecting the
There is no need to process the contact surface on the main conductor 9, and the main body 9 can be made smaller and cheaper, and can be easily assembled.
