The utility model, buckle is arranged on the end face of pedestal bently, and the U-shaped bayonet socket roof lower surface on buckle is provided with outstanding fin downwards, the bending buckle can be clamped power line, and by fin, power line is compressed, therefore, wire diameter to power line requires not tight, simplify manufacturing process, reduced cost, easy to use.

Description of drawings

The Line pressing buckle open mode structural representation that Fig. 1 provides for the utility model;

Fig. 2 is the upward view of the described Line pressing buckle of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, the utility model is made detailed explanation.

As shown in Figure 1 and Figure 2, the Line pressing buckle that provides of the utility model comprises pedestal 1 and buckle 2.

Pedestal 1 is the uncovered box-shaped in upper end, have front side wall 11, rear wall 12 and left side wall 13, right side wall 14, be provided with accordingly respectively the U-lag 15 of opening upwards on front side wall 11 and rear wall 12, and the bottom surface of U-lag 15 is arc, in the present embodiment, the bottom surface of U-lag 15 is semicircle, can increase like this contact area with power line, contact with power line better, increase clamping force.

Pedestal 1 and buckle 2 adopt PA or PP material integrated injection molding, buckle 2 is arranged on the end face of left side wall 13 of pedestal 1 bently, take closed condition as benchmark, the bottom surface of buckle 2 is provided with the U-shaped bayonet socket 21 that Open Side Down, the roof lower surface of U-shaped bayonet socket 21 is provided with outstanding fin 22 downwards, take open mode as benchmark, the left surface of the left side wall of U-shaped bayonet socket 21 is provided with grab 23, and the left surface of the right side wall 14 of pedestal 1 is provided with the buckle 16 that matches with grab 23.In the present embodiment, U-shaped bayonet socket 21 is between the rear wall 12 of the front side wall 11 of pedestal 1 and pedestal 1, during use, buckle 2 is covered on pedestal 1, grab 23 engages mutually with buckle 16, thereby between U-lag 15 and U-shaped bayonet socket 21, the effect of fin 22 is to compress power line with power clip, prevents play before and after power line.Grab 23 and buckle 16 releases can be opened buckle 2, take out power line.
