JPS5925085Y2 - T-branch conductor connection parts - Google Patents

Description

[Detailed explanation of the idea] This invention relates to connecting parts for T-branch conductors.

Conventionally, a T-shaped connecting fitting has been used to electrically connect three conductors branching into a T-shape.

According to the method using this connecting fitting, the contact pressure between the conductor and the fitting is determined by fastening bolts, and therefore, periodic maintenance and inspections are required to check whether the bolts are loosened.

The present invention takes the above points into consideration and provides a conductor connection component that does not require bolt fastening and has a simple structure.

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.

1, 2. 3 are conductors connected to each other in a T-shape, 4 is a contact cover consisting of a rectangular hexahedron, 5, 6
is a conductor insertion opening in which a partially semicircular recess is formed from both ends on one side of the contactor cover 4 in the direction of line A-A' shown in FIG. Contacts 7, 8 are installed, through which the conductors 1, 2 are inserted.

Reference numeral 9 denotes a through hole provided to penetrate in the direction of line B-B' perpendicular to the conductor insertion holes 5 and 6;
0 is inserted.

11 is a contact conductor consisting of a rectangular hexahedron, 12.13
is a conductor insertion opening in which a partially semicircular recess is formed on one side of the contact conductor 11 from both ends in the direction of line A-A', corresponding to the conductor insertion openings 5 and 6, and extending along the inner circumferential surface thereof. A leaf spring contact 14.15 is fitted.

16 is 13-B in the direction perpendicular to the conductor insertion port 12.13.
'It is a circular conductor insertion opening partially provided in the linear direction, and a leaf spring-like contact 17 is attached along the inner peripheral surface thereof, and a through-hole for the bolt 10 extends from the bottom surface of the insertion opening 16. It is.

Further, a thread is cut at the tip of the conductor 3 into which a bolt 10 is screwed.

In this way, the present invention includes the contact conductor 11, the corresponding contact cover 4, and the leaf spring-like contacts 7, 8, 14, 15, 17.
This is a connecting part of a conductor that branches into a T-shape and is composed of a fastening bolt 10 and a fastening bolt 10.

Note that FIG. 2 shows an enlarged cross section taken along the X-Y line in FIG. 1.

Next, a procedure for connecting T-branch conductors using the connecting parts of the present invention will be explained.

Each of the leaf spring-like contacts 7, 8, 14, 15, and 17 is pre-installed in the respective conductor insertion opening.

First, the contact conductor 11 is inserted with the insertion opening 16 facing the conductor 3 as it is.

In this case, it is inserted against the spring pressure of the plate spring contactor 17.

Next, insert the conductors 1 and 2 into the insertion opening 12 of the contact conductor 11, respectively.
．． Position it at 13.

In this case, if the conductor 3 is arranged vertically, the conductor 1
, 2 simply placed on the insertion opening 12.13.

Next, the contactor cover 4 is attached, and the bolts 10 are inserted and screwed into the conductor 3 to be fastened.

As described above, the conductors 1, 2.3 are connected together both structurally and electrically.

Note that the three conductors 1. 2. Disassembling step 3 can be done by reversing the previous connection procedure.

According to the present invention, the contact pressure of each conductor is maintained by the spring action of the plate spring contact, so that there is no need to manage the tightening force and loosening of bolts as in the past.

Moreover, since the number of component parts is small, it has practical effects such as assembly and disassembly of the T-shaped branch conductor is extremely easy.
