DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined nut type branch connector used for branching a current from a main line to a branch line.

[0002]

2. Description of the Related Art There is known an electric wire connector in which a main line and a branch line are arranged in parallel between an upper plate and a lower plate, and a central portion thereof is tightened with a bolt and nut. However, the main line and the branch line must be arranged in parallel and then connected via a connector.
Not only is it not always possible to obtain a sufficient connection, but the bolts and nuts have the drawback of loosening, which is insufficient for branch connection of large currents, causing corrosion at the connection between the main line and the branch line, and lacking reliability. there were.

[0003]

SUMMARY OF THE INVENTION According to the present invention, when connecting the main line and the branch line, the connecting member is rapidly assembled, and the main line, the branch line and the connector are firmly tightened.
The main line and the branch line are wrapped in a soft copper plate etc. without loosening the connection between the main line and the branch line due to the force applied from the outside,
Provided is a connector for preventing corrosion of a main line and tightening an inclined nut with a bolt to tighten the main line and a branch line.

As shown in FIGS. 13 and 14, the main wire 10 around which the main wire corrosion protection plate 12 is wound and the branch wire 11 are inserted into the torii type connector main body 1 and brought into close contact with the holding portion 1a. The seat 20 is inserted with its upper surface 21 facing upward and the upper surface 21 is
The lower part of the branch line 11 is supported via the main line corrosion protection plate 12. Next, the nut guide member 70 is inserted between the both side plates 2 and 3 of the torii type connector main body 1 from below the M-shaped wire seat 20, and the claw portions 81 and 82 are formed on the both side plates 2 and 3 of the torii type connector main body 1. The receiving parts 60 and 61 are fitted and mounted to stabilize.

The operation of the present invention will be described based on the above-described configuration of the present invention. First, the M-shaped wire seat 20, the bolt 30, the first inclined nut 40, and the second inclined nut 50 are removed from the torii type connector main body 1. . Then, both side plates 2 of the connector body 1
The lower part between and is opened. The main line 10 and the branch line 11 are wrapped by the S-shaped main body corrosion protection plate 12 as shown in FIG. The main line 1 and the branch line 11 wrapped by the main line corrosion protection plate 12
Are inserted in the connector main body 1 through the opening of the connector main body 1 while being held substantially in parallel in a column. Then, the outer peripheral surface of the main line 10 is fitted to the holding portion 1 a of the connector main body 1 via the main line corrosion protection plate 12. Next, the M-shaped wire seat 20 is placed on its upper surface 2.
1 is housed inside both side plates of the connector body 1 with
The branch line 11 is supported on the upper surface 21 of the M-shaped wire seat 20 via the main line corrosion protection plate 12. Next, the spring washer 33
2, the bolt 30 having the first inclined nut 40 inserted therein is inserted from one end of the M-shaped wire seat 20 to the other end as shown in FIG.
The female screw 38 is screwed and temporarily fixed.

As described above, since the first inclined nut 40 does not come off from the bolt by the spring washer 33 of the bolt 30, if the bolt 30 is kept rotating, the second inclined nut 50 moves rightward, and the M-shaped nut is moved. The wire seat 20 rises along the inner side surfaces of both side plates 2 and 3 of the connector body 1 in an equilibrium state, and the branch wire 11 is connected to the main wire 10 through the main wire corrosion protection plate 12, and at least the length of the torii connector body 1 is increased. More tightly pressed.

[0014]

According to the present invention, as described above, the height increases toward the center portion for guiding the first inclined nut 40 and the second inclined nut 50 formed inside the both side plates 2 and 3 of the torii type connector main body 1. First angled slopes 24, 2 formed in
5 and the first angled inclined surfaces 24, 25 and the second angled inclined surfaces 26, 27 in which the inclined surfaces are formed symmetrically and the holding portion 1a, the M-shaped wire seat 20 can rotate the bolt 30. The first moves to increase or decrease the distance between the first
It is guided by the tilt nut 40 and the second tilt nut 50 and can be moved up and down while maintaining a horizontal position. Therefore, the main line and the branch line are always gripped in parallel with the torii type connector main body, and the main line and the branch line can be quickly tightened and disengaged. It is small, strong, and has the effect of securely connecting the branch line to the main line and preventing corrosion of the main line.
Since the nut guide member 70 can be formed separately from the torii type connector main body 1, manufacture, adjustment, and assembly are easy. Further, there is an effect that the claw portions 81 and 82 can be stabilized without unnecessarily coming out of the torii type connector main body 1 and the like.
