[0002] During the erection of a circuit, the lines between iron towers need to be connected by strain clamps. Generally, the lines on both sides of the iron tower are not a straight-through line and are usually connected by tap-off connections. Due to the large tension of the conductor, the tap-off is difficult, time-consuming and laborious during the lap joint, and there are relatively large potential safety hazards.

A U-shaped hanging ring is fixed at the right end of the iron clamp. The right end of the clamp body is communicated with a hollow drainage clamp. The drainage clamp extends downwards. The steel sleeve passes through the upper end of the drainage clamp, and the upper end of the drainage clamp is communicated with the wedge-shaped clamp.

[0005] Further, a wedge-shaped through hole is provided at the right end inside the steel sleeve, and a circular through hole is provided at the left end. The wedge-shaped through hole is communicated with the circular through hole. A wedge-shaped part matching the wedge-shaped through hole is provided at the left end of the wedge-shaped clamp, and a clamping part is provided at the right end. Side ears are provided on both sides of the clamping part. The iron clamp fastens the wedge-shaped clamp through the side ears.

[0006] Further, the inner diameter of the wedge-shaped through hole is larger than the inner diameter of the circular through hole.

[0007] Further, a bending part is provided at the upper end of the drainage clamp, and an access opening is provided on the bending part. The wedge-shaped clamp enters the steel sleeve through the access opening.

[0008] Compared with the prior art, the beneficial effects of the utility model are: the utility model uses double fastening of the wedge-shaped clamp and the iron clamp, and the clamping effect is good. A firm clamping effect can be achieved without applying a large pressure. At the same time, a drainage clamp is provided on the clamp body, which is very convenient for tapping the conductor.

Specific implementation manner

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Please refer to Figure 1-2 , a new type of strain clamp, including a clamp body 1, a steel sleeve 3 is fixed on the clamp body 1. A wedge-shaped clamp 4 with a wire groove is sleeved inside the clamp body 1 and the steel sleeve 3. The right end of the wedge-shaped clamp 4 extends outward, and a clamping iron 5 is clamped thereon. The right end of the clamping iron 5 is fixed with a U-shaped hanging ring 6. The right end of the clamp body 1 is communicated with a hollow drainage clamp 2. The drainage clamp 2 extends downward. The steel sleeve 3 passes through the upper end of the drainage clamp 2. The upper end of the drainage clamp 2 is communicated with the wedge-shaped clamp 4. The wedge-shaped clamp 4 and the clamping iron 5 are used for double fastening, and the clamping effect is good. A firm clamping effect can be achieved without a large pressure.

[0014] In this embodiment, a wedge-shaped through hole 31 is provided at the right end inside the steel sleeve 3, and a circular through hole 32 is provided at the left end. The wedge-shaped through hole 31 is communicated with the circular through hole 32, and the inner diameter of the wedge-shaped through hole 31 is larger than the inner diameter of the circular through hole 32. The left end of the wedge-shaped clamp 4 is provided with a wedge-shaped part 41 adapted to the wedge-shaped through hole 31, and a clamping part 42 is provided at its right end. Side ears 43 are provided on both sides of the clamping part 42. The clamping iron 5 fastens the wedge-shaped clamp 4 through the side ears 43.

[0015] In this embodiment, the upper end of the drainage clamp 2 is provided with a bending part 21, and an access opening 22 is provided on the bending part 21. The wedge-shaped clamp 4 enters the steel sleeve 3 through the access opening 22. This setting not only completes the pulling of the wire to the right but also facilitates the tapping of the wire.

[0016] During use, the wire enters from the left end of the clamp body 1 and moves to the right along the wire groove inside the wedge-shaped clamp 4. When it reaches the clamping part 42, the wedge-shaped clamp 4 is pressed against the wire by fixing the clamping iron 5. The U-shaped hanging ring 6 is pulled at the right end to pull the wire to the right. At this time, the wedge-shaped clamp 4 is separated from the steel sleeve 3, and the U-shaped hanging ring 6 is hung on the iron tower to complete the connection of the wire and the iron tower. When it is necessary to tap the wire, another wire can be connected at the lower end of the drainage clamp 2.

[0017] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
