Abstract
The utility model relates to a single-core cable terminal clamp. The clamp comprises an upper clamp body, a lower clamp body and a rubber pad, wherein the upper clamp body is connected with the lower clamp body to form a through hole matched with a cable in an external diameter, the medial wall of the through hole is provided with a thread, and the rubber pad is arranged in the through hole. The single-core cable middle clamp has the advantages over the prior art of flexibility, convenience, long service life, stability and reliability.
Description
Technical field
The utility model relates to a kind of cable and uses anchor clamps, especially relates to a kind of single-core cable terminal and uses anchor clamps.
Background technology
Along with electrical network constantly enlarges and renewal; The design of high pressure and ultrahigh voltage power cable tunnel and application increase day by day; The electric pressure of well-known cable is high more, and its line loss is more little, and superhigh pressure, length, heavy in section, variation and high reliability are current power cable technology trends.In transformer station's cable floor, cable trough, cable tunnel and other power cable structures, be used for supporting the support with attached cable, installation and operation has crucial effect to cable.All adopt the steel construction cable bearer in the common engineering; And cooperation clamps cable; Aspect the use of cable cleat, during laying, prior cable mostly adopts band, plastic clamp, traditional fixture rail or common aluminum alloy anchor clamps, can not effectively retrain cable; Cable is axially adopted vertically all solutions well of electric power influence between living slippage and cable, and this anchor clamps have following problem:
(1) environmental suitability is poor: the intensity and the decay resistance of existing anchor clamps are all poor, are not suitable in the more abominable tunnel of environment, using.
(2) if be metal fixture, be used for high voltage single-core cable, when cable jacket damages, may form ground connection circulation or produce gap discharge, cause cable jacket further to damage through anchor clamps.
(3) high pressure list core electric cable with large cross-section; Be in operation because the effect of alternating electromagnetic field; Can on electroconductive magnetic medium metal fixture, produce tangible eddy current loss and magnetic hysteresis loss, cause backing temp to raise, thereby the cable jacket surface temperature is raise; The medium thermal resistance increases on every side, influences the cable transmission capacity.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of single-core cable terminal flexible, that the life-span is long to use anchor clamps for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: anchor clamps are used at a kind of single-core cable terminal; It is characterized in that; These anchor clamps comprise upper clamp, lower clamp and rubber packing; Described upper clamp and lower clamp are connected to form a through hole that is complementary with the outside diameter of cable, and this through hole madial wall is provided with screw thread, and described rubber packing is arranged in the through hole.
Described upper clamp is arch-shaped structure, or the semicircular arc structure.
Described lower clamp top and upper clamp are the mirror image setting, and the lower clamp bottom is provided with on the holder, and this holder is provided with holddown groove, bolt a pass this location notch with clamps in position to be installed.
Described upper clamp and lower clamp are connected to form the through hole of an adjustable size through bolt b.
Described upper clamp and lower clamp two ends are provided with connecting hole, and bolt b passes said connecting hole and upper clamp is connected fixing with lower clamp.
Described connecting hole is a waist-shaped hole.
Described rubber packing is the black neoprene.
Compared with prior art, the upper clamp of the utility model anchor clamps and lower clamp are the split setting, regulate the size that it connects the through hole of back formation through bolt; To adapt to the cable of various outer diameter size, the through hole madial wall is provided with screw thread, makes cable termination can be stably fixed in the anchor clamps; On the base of anchor clamps holddown groove is set; Because holddown groove has certain length, therefore can adjust its horizontal level within the specific limits, flexible.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment 1
As shown in Figure 1, anchor clamps are used at a kind of single-core cable terminal, and these anchor clamps comprise upper clamp 1, lower clamp 2 and rubber packing 4; Upper clamp 1 is arch-shaped structure, and lower clamp 2 tops and upper clamp 1 are the mirror image setting, and the lower clamp bottom is provided with on the holder 3; This holder 3 is provided with holddown groove 5, and therefore this holddown groove 5 can adjust the anchor clamps horizontal level within the specific limits by certain length; Bolt a7 pass this location notch with clamps in position to be installed, described upper clamp 1 is provided with connecting hole with the lower clamp two ends, this connecting hole is a waist-shaped hole; Anchor clamps can be finely tuned in the horizontal direction, and bolt b6 passes said connecting hole upper clamp 1 and lower clamp 2 is connected to form the through hole of an adjustable size, to adapt to the cable of various outer diameter size; This through hole madial wall is provided with screw thread, is provided with rubber packing 4 in this through hole.
Described upper clamp is the semicircular arc structure, and described lower clamp top and upper clamp mirror image are provided with, and all the other are with embodiment 1.
