Description

[Detailed description of the invention] The present invention relates to a connector for jumper wires used in so-called live line work, such as replacing switches on overhead power distribution lines, changing wires and replacing retaining arms, etc. The purpose of this is to make the handle rod bendable and rotatable so that various operations can be performed easily.

Conventionally, when carrying out live line work, such as replacing a switch on a distribution line, as shown in Figure 1, the upper end of the main line a, which is strung over a utility pole through an insulator, is fitted with hems in advance. Two connectors C and C, each end of which is screwed, are clamped together to form a bypass for the load current, and a protective device such as an insulating rubber sheet is installed across the connectors in the clamped mounting part d, d.
After winding and encasing the switch e, remove the switch e from the main line a, connect and install the new switch to the main line a, and then attach the switch to the main line a.
In this case, the connectors c and c are loosened and removed together with the edge-wrapping wire in the "on" state. There was a risk that the hanging protrusion would impede work such as switching switch replacement, and protective equipment such as insulating rubber sheets d, d
It has drawbacks such as being troublesome to wrap.

In the present invention, as described above, the handle rod is formed to be bendable and rotatable, and after being clamped and fixed, it is folded along the main line a, thereby eliminating the drawbacks of the conventional handle.

Next, an embodiment of the present invention shown in the accompanying drawings will be described in detail.

In Fig. 2, reference numeral 1 denotes a handle rod, which is made of a hollow insulating material with an opening at the upper end and has a required length, and a socket fitting 2 having a stepped square hole 2a therethrough is fitted into the upper opening 1a. has been done.

Reference numeral 3 denotes a feed screw, and a U-shaped clamping frame 4 is screwed onto the upper end, and a seat 5 is rotatably engaged with the tip of the feed screw 3 located inside the clamping frame 4, as in the conventional case. A clamp portion 6 is formed at the lower end, and the stepped square hole 2 of the socket fitting 2 is formed on the circumferential surface of the socket fitting 2.
A square tubular fitting 1 that conforms to the shape of a square tube 1a is firmly fitted, and the connecting pin 8 inserted through the center of the fitting 7 is constantly pulled through a coil spring 9 to the lifting rod in the handle 1. 10, the vertical axis line X-X is aligned with the upper end two prongs 10a of
It is pivotally connected.

The lifting rod 10 is fixed by fitting its upper end into the stepped square hole 2a of the socket fitting 2, and by engaging a stopper 11 attached to its lower end with a pressure contact spring 12 attached to the inner surface of the handle rod 1. , the fixation can be released via a push button 13 provided on the handle rod 1.

Next, how to use it will be explained.

For example, when replacing a switch, etc., hook the clamping frame 4 of the connector C onto the main line a as shown in the first figure, rotate it by grasping the handle rod 1, and rotate the connector C as shown in the second figure. After tightening the main line a with the clamp part 6 formed by the clamping frame 4 and the catch seat 5 at the upper end of the feed line rod 3 to form a bypass by the hem-roaming line (see Fig. 4), the third As shown in the figure, when the push button 13 is pressed to disengage the pressure contact spring 12 and the stopper 11, and the handle rod 1 is pulled downward, the garden fitting 7 escapes from the stepped square hole 2a of the socket fitting 2, and can be raised and lowered. The rod 10 and the stopper 11 are the socket fittings 2
Since it rises until it touches the bottom surface of the feed line rod 3 and handle rod 1,
The coil spring 9 can be freely bent around the shaft attachment part of the continuous chamber pin 8, and the coil spring 9 is temporarily compressed during the bending, but after the bending is completed at a nearly right angle, it returns to the dead center. The refracted state is maintained by this elastic force as it spreads out again beyond this point.

That is, the bent handle rod 1 is kept horizontal and there is no risk of it sagging due to its own weight.

Moreover, since the feed line rod 3 can be rotated around the connecting pin 8 after the garden fitting 7 has escaped upward from the socket fitting 2, the handle rod 1 can be bent in any direction. can.

In addition, when removing connector C from main line a, turn handle lever 1 downward against coil spring 9 and push up handle lever 1 at the same time. Since the upper end of feed line lever 3 is still fixed to main line a, The attachment fitting 1 enters into the stepped square hole 2a of the socket fitting 2, and the elevating rod 10 connected thereto is also pressed down, and the stopper 11 engages with the pressure spring 12 again to stabilize and return to the initial state. Rotate rod 1 and clamp part 6
can be loosened and removed from the main line a.

According to the present invention, after attaching the hem mawashi to the main line a,
The handle rod 1 can be pushed up almost horizontally along the main line in its tightened state, and in this case, there is no risk that the handle rod 1 will sag due to its own weight, and the direction of the push-up can be either left or right. , it is easy to operate, and as mentioned above, this structure reduces the number of objects obstructing the operator's head, making various operations easier, and at the same time, it is easier to attach protective equipment such as an insulating rubber sheet to cover the connector. be able to.

Claims (1)

[Scope of utility model registration request] A clamp part is formed by screwing a clamping frame onto a feed screw connected to the upper end of a vertical cylindrical handle, in which the upper end of the handle is a square hole and the lower end of the feed screw is a square tube that engages with each other. At the same time, an elevating rod is housed in the handle lever so that it can be freely engaged with and detached from the inner surface of the handle via a pressure spring and a push button, and the lower end of the feed screw and the upper end of the elevating rod are constantly pulled by a spring so that the shaft can be bent freely.
