technical field

The utility model relates to the field of electric equipment, in particular to a new type parallel groove clamp.

Background technique

The parallel groove clamp is used for the connection of small and medium-sized aluminum stranded wires or steel cored aluminum stranded wires and the steel strands of overhead lightning conductors at positions that do not bear tension, and the parallel groove clamps are also used for jumping of non-linear towers line connection. The existing parallel trench clamps are only suitable for connecting bare wires, but not for connecting wires with insulating sheaths. The existing parallel trench line clamp has poor insulation performance.

Utility model content

The purpose of the utility model is to overcome the above disadvantages and provide a new type parallel groove clamp, which is not only suitable for connecting electric wires with insulating sheaths, but also has good insulation.

The purpose of this utility model is achieved in the following way: a new type parallel ditch clamp, including an insulating shell (1), the inside of the insulating shell (1) is provided with two threading holes (7) in parallel on the left and right, between the two threading holes (7) A cuboid-shaped conductive core block (2) is arranged between them, and the upper and lower parts of the conductive core block (2) are connected to the insulating shell (1), and the left and right sides of the insulating shell (1) are symmetrically provided with several pairs of screw holes (6 ), the conductive core block (2) is provided with several threaded holes (5) corresponding to several pairs of screw through holes (6), the threaded holes (5) are coaxial with the screw through holes (6), and the threaded holes (5) are provided with There are concave threads, each screw hole (6) is equipped with a pointed screw (3), the thread of the pointed screw (3) coincides with the concave thread of the threaded hole (5), and the end of the pointed screw (3) is set There are insulating turntables (4).

Preferably, the insulating shell (1) is made of rubber material.

Preferably, the conductive core block (2) is a copper alloy material.

Preferably, the pointed screw (3) is made of copper alloy material.

Preferably, the insulating turntable (4) is made of insulating plastic, and the pointed screw (3) is connected to the insulating turntable (4) by injection molding.

The utility model has the advantages that: the utility model's new parallel ditch clamp has a simple structure and is easy to install, solves the problem that the existing parallel ditch clamp is only suitable for connecting bare wires, and can connect electric wires with insulating sheaths, and because The structure is simple, the material is soft, and the corrosion resistance is good, which greatly improves the insulation of the clamp.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The utility model is a new parallel groove clamp, as shown in accompanying drawings 1 and 2, comprising an insulating shell 1, the insulating shell 1 is made of rubber material, and two threading holes 7 are arranged in parallel on the left and right inside the insulating shell 1, It is used to pass the electric wire through the threading holes 7. A rectangular parallelepiped conductive core block 2 is arranged between the two threading holes 7. The conductive core block 2 is made of copper alloy material. The upper and lower parts of the conductive core block 2 are connected with the insulating shell. 1 connection, the left and right sides of the insulating shell 1 are symmetrically provided with several pairs of screw through holes 6, and the conductive core block 2 is provided with several screw holes 5 corresponding to the several pairs of screw through holes 6, and the threaded holes 5 are coaxial with the screw through holes 6. A concave thread is provided in the threaded hole 5, and each screw hole 6 is equipped with a pointed screw 3, and all the pointed screws 3 are copper alloy materials, and the thread of the pointed screw 3 matches the concave thread of the threaded hole 5, and the pointed screw 3 is made of copper alloy. The end of the head screw 3 is provided with an insulating turntable 4, the insulating turntable 4 is insulating plastic, and the pointed screw 3 and the insulating turntable 4 are connected by injection molding.

This parallel ditch clamp is specifically used in this way: insert the wires with insulation sheath directly into the two threading holes 7 of the insulation shell 1, then hold the insulation turntable 4 and pass the pointed screw 3 through the screw hole 6 and the wires, Continue to rotate the insulating turntable 4 to screw the pointed screw 3 and the threaded hole 5 of the conductive core block 2 to fix each other, and the two electric wires, the pointed screw 3 and the conductive core block 2 form a path, and the purpose of connecting the two electric wires is achieved.

Finally, it should be noted that: obviously, the above-mentioned embodiments are only examples for clearly illustrating the present application, rather than limiting the implementation manner.
