Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for connecting the ends of two contact wires. Conventionally, the end portions of both contact wires were arranged parallel to each other for an appropriate length, a spacing member was sandwiched between them, and the end portions were tightened from both sides with a pair of scissor members. In contrast, the present invention is characterized by making it possible to butt connect the ends of both contact wires, thereby significantly simplifying the work.

Examples will be described with reference to the drawings.

The connecting fitting 1 has an L-shaped cross section, the lower surface of the horizontal side is bifurcated, and teeth into which the contact wires T1 and T2 can be inserted are formed. Further, a screw hole is bored on the back surface into which a bolt 2 is screwed so that the inserted contact wire can be retained. This connection fitting has vertical sides facing each other.
Use pairs. The connecting link 3 has a rectangular shape, and both ends thereof are pivotally connected to respective bases of a pair of connecting fittings by pins 4. The spacing member 5 is T-shaped and is pivoted to the center of the connecting link by a pin 6 at the lower end of the leg. Further, the top side is inserted between the opposing vertical sides of both the connecting fittings, so that the vertical sides can be held vertically.

In the present invention constructed as described above, the ends of the contact wires T1 and T2 are respectively inserted into a pair of connecting metal fittings that have been assembled in advance in the connecting link, abutted against each other, and fastened with bolts 2. The tension of the contact wire is supported by the spacing member 5, and the abutting point between the two contact wires does not become a discontinuous point.

The known connection device, as mentioned in the introduction, has three separate
The parts are bolted together on site. This task of tensioning both contact wires at the same time is extremely troublesome. Furthermore, since the ends of the two parallel contact wires are pulled through the separating member, the entire device is twisted around the center of the separating member. The contact wire also becomes bent, which is undesirable. In contrast, in the present invention, after fixing one contact wire, it is possible to move on to fixing the other contact wire, making the work easier. There is no room for twisting in the contact wire. The above are the features of the present invention.
