Abstract

The utility model relates to a cable wire fixed head structure which comprises a joint, a pressing member, a clamping member and an inner lining member, wherein the pressing member is assembled with the joint; the clamping member is arranged between the joint and the pressing member; the inner lining member is arranged in the clamping member. The coating part of the inner lining member extends to an appropriate length, and can extend the outer sides of the clamping member and the pressing member when assembled, thereby, the inner lining member is twist-resistant under the dynamic action. Girding sections in a step shape or a gradually shrinking shape are arranged in the coating part, thereby, the utility model is cut to use by cable wires with different linear diameters, and plays the actions of multi-section type water prevention and fixed cable wire protection.

Description

Cable is header structure fixedly

Technical field

The utility model relates to fixedly header structure of a kind of cable, and is particularly a kind of in order to the attached cable line, and has the fixedly header structure of waterproof and fixing protection cable.

Background technology

Fixedly header structure is as shown in Figure 1 for employed on the market at present cable, this cable fixedly header structure comprises: a joint 1a, one with the forcing piece 2a of aforementioned joint 1a winding, one is disposed at the clamping element 3a between aforementioned joint 1a and forcing piece 2a, and an inner piece 4a who is disposed at aforementioned clamped part 3a inside.

In use, earlier inner piece 4a is built in clamping element 3a inside, after again cable 5a being passed forcing piece 2a, inner piece 4a and joint 1a in regular turn this moment, when the 14a interlocking of the junction surface of the socket part 21a of forcing piece 2a inside and joint 1 body 11a, the convergent inwall 22a of this forcing piece 2a interior extremity will push the clamp clip 31a of clamping element 3a, after causing clamp clip 31a internal diameter convergent, allow the compression part 32a of clamp clip 31a be pressed 42a, to reach clamping cables line 5a in coating portion.Because the 42a of coating portion of aforesaid inner piece 4a does not extend forcing piece 2a outside; to wind such as external force such as poor weather typhoon or continuously fast the mechanical cable line in the working motion operate more not anti-turning round back and forth; the crippling start of cable pair node place generation just difficulty provides waterproof and fixing protection, also can't be fit to the not cable 5a use in collinear footpath simultaneously.

In addition, also have fixedly header structure of a kind of cable, see also Fig. 2, the difference of itself and Fig. 1 only is extended with one spiral helicine in order to coat the 20a of coating portion of cable 5a at forcing piece 2a end.Though; the 20a of this coating portion can fix protection cable 5a; but the 20a of this coating portion is a hollow out state; still do not have waterproof action; when being subjected to external force effect swing, supporting mutually during more owing to spiral coil sheet complications and pull very little more not anti-the turning round of amplitude of fluctuation; be not enough to keep out high wind or the swing significantly that brought of mechanical movement fast, the fixing head of the cable of metal also can't be made the spiral helicine extension of this kind coating portion in addition.

Summary of the invention

The purpose of this utility model is a fixedly header structure of a kind of cable.

Above-mentioned purpose of the present utility model is to realize like this, a kind of cable is header structure fixedly, comprise: a joint, one with the forcing piece of aforementioned joint winding, one is disposed at the clamping element between aforementioned joint and forcing piece, and an inner piece that is disposed at aforementioned clamped part inside, and it is characterized in that: inner piece is a ducted body, front end has the stopper of keeping out in above-mentioned clamping element opening part, and extensible in the coating portion of clamping element and forcing piece outside when stopper undertakes an assembling.

The utility model has the advantages that; but the fixing head of cable is the clamping cables line not only; but also have waterproof and the fixing effect of protecting cable; particularly to wind such as external force such as poor weather typhoon or the mechanical cable line swing running significantly back and forth in the working motion fast continuously, the crippling that cable pair node place produces is made kinetic energy fixing protection effectively is provided.

Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment

See also Fig. 3 A, Fig. 3 B, Fig. 3 C, cable of the present utility model shown in Figure 4 fixedly header structure decompose and three-dimensional combination schematic appearance.As shown in the figure, cable of the present utility model fixedly header structure comprises: the forcing piece 2, of a joint 1, one and aforementioned joint 1 winding is disposed at the clamping element 3 of 2 of aforementioned joint 1 and forcing pieces, and an inner piece 4 that is disposed at aforementioned clamped part 3 inside.Use aforementioned components has waterproof and fixing protection cable 5 with group formation one fixedly head.

The above-mentioned joint of carrying 1 has a hollow body 11, has a blocking part 12 on this body, the

junction surface

13,14 that on the body 11 of 12 front and back, blocking part, respectively has a flank, engage the locking part 16 of a pad 15 and a tool nut form on aforesaid junction surface 13, the aforesaid junction surface 13 of mat, pad 15 and locking part 16 provide the body 11 of joint 1 fixedly to be assembled in dividing plate or the first-class fixed-site of wall;

This forcing piece 2 is ducted bodies, and its interior forward end has a socket part 21 that is flank and combines with above-mentioned junction surface 14, and is a convergent inwall 22 (shown in Fig. 6 figure) in forcing piece 2 interior extremity;

This clamping element 3 is ducted bodies, has the clamp clip 31 that plural number has elastic stage on it, have a compression part 32 (as shown in Figure 7) on each clamp clip 31, this clamp clip 31 presses on inner piece 4 compression part 32 on the clamp clip 31 after being subjected to convergent inwall 22 extruding of forcing piece 2 inside;

This inner piece 4 preferablies are selected from the made ducted body of elastomeric material, front end has the stopper 41 of keeping out in above-mentioned clamping element 3 opening parts, and it is extensible in the coating portion 42 of forcing piece 2 outsides when stopper 41 undertakes an assembling, can be the section of tightening 43 of one stepped (as shown in Figure 5) or gradually-reducing shape with coating portion 42 inner walls, can cut to cooperate different cable 5 lines directly to use;

Above-mentioned inner piece 4 comprises diameter difference between mat coating portion 42 and the stopper 41 and forms for example 44 or 45 (shown in Fig. 3 B or Fig. 3 C) among the figure of a depressed part preferably, presses and is installed with further to be beneficial to clamping element.
