[0002] The electric connection clamp is used to transmit current during operation. Especially when there is a line fault, it needs to bear a large instantaneous current. Therefore, it is required to have a firm connection and good electrical conductivity. The electric connection clamp is widely used in the fields of electric power, communication, rail transit, etc. Especially in the places with more double-line power supply or return current structures in the catenary of electrified railways, it provides a reliable electrical connection solution.

[0003] However, the existing connection clamps have the following disadvantages:

[0004] (1) For the existing connection clamps, the clamping function is weak. Usually, only one connecting wire can be clamped during use. When it is necessary to clamp two connecting wires, the number of connection clamps needs to be increased, which easily causes the problem of increasing the clamping and fixing cost of the connecting wires.

[0005] (2) For the existing connection clamps, the adjustment function is weak. When using, it is suspended on the top of the building body by means of fixing bolts. When it is necessary to adjust the suspension height, other fixing tools need to be used to remove and refix it, which easily causes the problem of prolonging the installation and fixing time of the connecting wires.

Through the arrangement of a plurality of first C-shaped clamps 3 and second C-shaped clamps 7, it is convenient to clamp and fix two different connecting wires at the same time, thus achieving the effects of expanding the use range of the overall device and reducing the use cost of fixing the connecting wires;

[0027] As Figure 1 shown, a first rectangular column 9 is fixedly arranged in the middle of the top end of the upper shell 4.

Rotate the rotating block 8 to make the screw 5 rotate. The screw 5 drives and presses against the bottom fixed plate 6, and the fixed plate 6 drives the second C-shaped clamping plate 7 at the bottom to move downward, so as to clamp and fix the connecting wires placed inside the first C-shaped clamping plates 3. Through the settings of multiple first C-shaped clamping plates 3 and second C-shaped clamping plates 7, it is convenient to clamp and fix two different connecting wires at the same time, thereby achieving the effects of expanding the use range of the overall device and reducing the use cost of fixing the connecting wires. At the same time, through the settings of the positioning block 13, rectangular plate 14 and pull rod 15, when in use, adjust the position of the first rectangular column 9 inside the second rectangular column 10.

By providing multiple first limiting grooves and second limiting grooves, the effects of facilitating the operator to adjust the hanging height of the connecting wires according to actual needs and reducing the installation time of the overall device are achieved. Through the settings of the fixed cylinder 16, fixed column 18 and limiting column 19, when in use, the bottom end of the fixed column 18 is fixedly connected to the top end of the fixed plate 6. Through the settings of multiple fixed cylinders 16, the two sides of the fixed plate 6 can be fixed, thereby achieving the effect of preventing the fixed plate 6 from rotating synchronously when the screw 5 rotates. Through the settings of the connecting column 22, positioning plate 23 and fixing nut 25, when in use, pass the connecting column 22 through the first connection hole 20 and the second connection hole 21, so that the positioning plate 23 at the bottom end of the connecting column 22 is closely attached to the bottom of the lower housing 1. Then thread the fixing nut 25 onto the top end of the connecting column 22 and rotate the fixing nut 25 to make the lower housing 1 closely attached to the upper housing 4, thereby achieving the effect of facilitating the first C-shaped clamping plate 3 and the second C-shaped clamping plate 7 inside the lower housing 1 and the upper housing 4 to clamp and fix the connecting wires. Through the settings of the first insulating layer 26 and the second insulating layer 27, when in use, the first C-shaped clamping plate 3 and the second C-shaped clamping plate 7 can have insulating properties, thereby avoiding the effect of the clamped connecting wires leaking electricity and damaging the first C-shaped clamping plate 3 and the second C-shaped clamping plate 7.
