Description

Technical Field

[0001] The utility model relates to the technical field of wire clamps, in particular to a rotatable conical wire clamp. Background Art

[0002] Wire clamps are iron or aluminum metal accessories that can be fixed on wires. Most of them need to withstand large tensile forces during operation, and some must also ensure good electrical contact. Wire clamps are mainly divided into: equipment wire clamps, fusible wire clamps, wire holding clamps, terminal wire clamps, piercing grounding wire clamps, tightening wire clamps, insulation piercing wire clamps, double-headed wire clamps, lead-in wire clamps, etc.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN219458623U discloses an interlocking self-locking wedge-shaped tension clamp for overhead insulated conductors, comprising two interlocking self-locking slot shells, two interlocking insulating core wedges and a pull ring. The two interlocking self-locking slot shells are assembled into a whole, and the two interlocking insulating core wedges arranged face to face are inserted into the rectangular holes of the two interlocking self-locking slot shells. The interlocking insulating core wedges are connected to form a wedge core whose inner surface forms a clamping groove with conical inverted teeth, and the insulated conductor is located in the clamping groove between the two interlocking insulating core wedges. The utility model is an interlocking self-locking wedge-shaped tension clamp for overhead insulated conductors. The clamping groove of the symmetrical wedge core body is designed with beveled edges on both sides to increase the fit of the conductor. The interlocking self-locking wedge-shaped tension clamp is easy to install on site and has a reliable structure. It is suitable for the tension section of overhead insulated conductors.

[0005] However, the above patent still has some problems in actual use. The most obvious one is that the friction between the wire clamp and the cable needs to be improved, and the direct contact between the cable and the wire clamp can easily cause the outer skin of the cable to be damaged by the clamp.

[0006] To this end, we proposed a rotatable conical wire clamp to solve the above-mentioned drawbacks. Utility Model Content

[0007] The utility model aims to provide a rotatable conical wire clamp in order to solve the shortcomings in the prior art.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rotatable conical wire clamp, comprising an outer shell, the surface of the outer shell is fixedly connected to a connecting frame by a rotating seat, and a bolt is installed on the connecting frame, a first conical wire clamp and a second conical wire clamp are installed inside the outer shell, the inner walls of the first conical wire clamp and the second conical wire clamp are both bonded with protective pads by Velcro, a fitting strip is installed on the first conical wire clamp, and a fitting groove is opened on the second conical wire clamp, and the fitting strip fits with the fitting groove.

[0009] Preferably, the first tapered wire clamp and the second tapered wire clamp have the same structure.

[0010] Preferably, the diameter of one end of the first tapered wire clamp and the second tapered wire clamp is larger than the diameter of the other end.

[0011] Preferably, the length of the protective pad is the same as the length of the first tapered wire clamp and the second tapered wire clamp.

[0012] Preferably, the lengths of the first tapered wire clamp and the second tapered wire clamp are greater than the length of the housing.

[0013] Preferably, the first tapered wire clamp and the second tapered wire clamp are made of PP.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the utility model, by arranging protective pads on the inner walls of the first conical wire clamp and the second conical wire clamp, on the one hand, the friction between the cable and the first conical wire clamp and the second conical wire clamp can be greatly improved, and the clamping effect and stability of the first conical wire clamp and the second conical wire clamp on the cable can be improved; on the other hand, the risk of damage to the outer skin of the cable can be reduced, thus achieving two goals at one stroke, and the utility model has a simple structure and low cost.

[0016] 2. In the utility model, the fitting strip and the fitting groove are arranged to cooperate with each other. When installing, the fitting strip on the first conical wire clamp is fitted with the fitting groove on the second conical wire clamp, which can effectively improve the stability between the first conical wire clamp and the second conical wire clamp, and the first conical wire clamp and the second conical wire clamp are connected more tightly, effectively reducing the risk of misalignment between the first conical wire clamp and the second conical wire clamp.
