Description

[Detailed description of the invention] The present invention relates to a connecting device for a long insulated trolley wire, in which a conductor 2 is attached over the entire length to a long insulated trolley wire body 1 made of an insulating material to form an insulated trolley wire 3. and conductor 20
Both ends of the conductor 2 are made to protrude from the end face of the insulated trolley wire main body 1, and the protruding ends of the conductor 2 are bent upward to form a locking piece 4.
Insulated Toro that is adjacent to each other in the longitudinal direction! J-[This relates to an insulated trolley wire connection device in which locking pieces 4, 4 of 3, 3 are butted against each other, and the pair of locking pieces 4, 4 are clamped at a connecting joint 5.

The insulated trolley wire is installed, for example, on the ceiling parallel to the hoist rail, and as the hoist travels, the trolley collector runs along the insulated trolley wire, and power is supplied to the hoist via the trolley collector. Conventionally, such insulated trolley wires were connected as shown in FIG. 1.

That is, the protruding conductors 2.2 of adjacent insulated trolley wires 3, 3 are sandwiched between two metal fittings 6, 6, and these two metal fittings 6, 6 are tightened with four bolts 7. As a result, the conductors 2, 2 are connected by the clamping force of the metal fittings 6.degree. 6, and the insulated trolley wires 3, 3 are connected in this way.

8 is a cover that covers the connecting portion of the insulated trolley wires 3, 3.

However, in this case, tightening the bolt γ is troublesome and takes time, and a special tool 9 is required for tightening the pole 7, and furthermore, a long insulated trolley wire is required. 3 applies tension to both ends to eliminate meandering, so strength is required at the connection, but the connection is made by sandwiching the ends of conductor 2 and 2 between metal fittings 6. Therefore, the tensile strength applied to the connection part is related to the tightening torque of the bolt 7 that tightens the metal fittings 6 and 6, and the tightening torque of the bolt 1 must be regulated during construction. With difficulty, two more metal fittings 6, 6
The tightening of the bolt 7 requires strength that can withstand torque, resulting in high costs.

The present invention has been devised in view of the above points, and is an insulated trolley wire connecting device that can easily connect insulated trolley wires without the need for one-bolt tightening, and has excellent connection strength. The purpose is to provide the following.

The present invention will be described in detail below using examples.

The contactless trolley wire 3 is formed as shown in Fig. 2 by burying a conductor 2 over the entire length of a long insulated trolley wire main body 1 made of an insulating material such as synthetic resin, with the lower surface exposed. Both ends of one conductor 2 are made to protrude beyond both ends of an insulated trolley wire main body 10.

Insulated trolley wire 3 is used for construction materials such as ceilings...NGAR 10
The insulated trolley wire 3 is connected as follows.

First, the end of the conductor 2 protruding from the insulated trolley wire main body 1 is bent upward, and this bent piece is used as the locking piece 4, and then the locking piece 4 of the insulated trolley wires 3, 3 adjacent to each other in the longitudinal direction is used.
4, and by fitting the ring-shaped connecting joint 5 into the pair of locking pieces 4.4, and then turning the tip of the conductor 2 back as a folded piece 11, the connecting joint 5 is assembled. Stop pulling out.

In this way, as shown in FIG.
The insulated trolley wires 3, 3 are connected to each other, and the locking pieces 4, 4 at the ends of the conductors 2, 2 are connected.
It is also possible to make an electrical connection between the conductors 2 and 2 by butting them together.

After the connection is made, a cover 12 made of an insulating material is attached to the connection part of the insulated trolley wires 3, and the exposed conductor 2 is removed.
, cover the ends of 2.

To install the cover 12, connect the side legs 13 to the insulated trolley wire main body 1.
.

The insulated trolley wires 3, 3 connected in this way and supported by the banger 10 are tensioned at T by a spring 17 through tension insulators 16 from both ends to prevent meandering as shown in FIG.
is added.

A track 18 is provided protrudingly on both sides of the insulated trolley wire 3, and the trolley collector 200 is slid by fitting the running groove 19 into the track 18.
0 runs along the insulated trolley wire 3, and the current collector 21 protruding from the trolley collector 20 slides into contact with the conductor 2 as it runs, thereby supplying power from the conductor 2 to the load via the current collector 21. .

Reference numeral 22 denotes a connection track that connects the tracks 18 and 18 of the insulated trolley wires 3, 3.

As described above, in the present invention, the conductor is made to protrude from the end face of the insulated trolley wire body, and this protruding conductor is bent upward to serve as a locking piece, so that the locking pieces of adjacent insulated trolley wires Since the pair of locking pieces and the connecting joint are used to butt the wires together, there is no need to use bolts to connect the insulated trolley wires, which eliminates the troublesome work of tightening the bolts and the special tools needed to tighten the bolts. This is not necessary, and even if tension is applied to the insulated trolley wire, the connection is made by clamping the locking piece at the end of the conductor with the connection joint.
When tightening bolts, there is no need to consider torque, etc., and a strong connection can be achieved, and the connection structure can also be simplified.
