Description

A kind of improved cable is fixed an integrated structure

Technical field

The utility model relates to the fixing integrated structure of a kind of improved cable; relate in particular to a kind of can effectively catching; and be not subjected to external force to influence the fixedly header structure that protection tube gets loose; have waterproof and dustproof simultaneously and prevent and destroy in the worm ant access arrangement system, with the fixing integrated structure of the cable of guaranteeing device systems safety.

Background technology

In the prior art, for example, " cable protective tube and joint integrated structure " patent that No. the 295317th, the TaiWan, China patent gazette, it is the flexible pipe that a surface is provided with circulus that this patent is mentioned this protection tube, this joint is made up of a body and an interlocking body in addition, and at the built-in O shape ring that is provided with of body; And it is characterized in that: the outer ring surface that the interlocking body of this joint is sheathed in advance this protection tube; then at the terminal holding one spacing member of protection tube; again with the body and the interlocking body interlocking of joint; and the spacing member of packing and being combined into one; and this spacing member is a hollow ring body; lead with the oblique angle on its anchor ring apical margin limit; and on anchor ring, form plural rubber-like banking stop; its inner ring surface apical margin of banking stop is established with overhead kick; overhead kick is arranged in the depressed part of protection tube circulus; then be provided with oblique protuberance at the lateral surface apical margin, tiltedly protuberance is oppressed by the body inner ring surface, makes protection tube; spacing member and joint three driving fit are integral.

Though above-mentioned banking stop utilizes overhead kick,, avoid protection tube influenced by external force and get loose to catch on the depressed part of protection tube.But during practice, this banking stop is counted point and is pressed in the depressed part that is arranged in the protection tube circulus, is not around protection tube depressed part all one's effort clip with 306 °.Moreover still have a gap between banking stop another side and the inner body wall; this gap then provides the space of the elastic force deflection of banking stop own; therefore cause banking stop to remain and clamp protection tube by elastic force own; cause non-complete limited of protection tube to clamp; therefore when protection tube is influenced by external force; this banking stop still can't clamp protection tube; get loose and allow protection tube produce, the cable that allows protection tube inside be disposed can not get the function protecting completely and can't have waterproof and dustproof and prevent to destroy in the worm ant access arrangement system.

Summary of the invention

Main purpose of the present utility model is the defective that overcomes above-mentioned prior art; the utility model is to fixedly header structure redesign of cable; provide a kind of improved cable to fix an integrated structure; it allows fixes effectively ring-type clamping protection tube of head; allow protection tube not influenced by external force, and produce any phenomenon that gets loose with fixing head.

The purpose of this utility model realizes that by following technical proposals improved cable provided by the utility model is fixed an integrated structure, and it includes:

One joint has a body on it, have a blocking part on this body, respectively has a junction surface on the body before and after this blocking part, and front end undertakes plural intermediate plate at described one junction surface;

One forcing piece, it is to be connected on the above-mentioned junction surface, has a socket part and perforation on it, is formed with a compressive plane between socket part and perforation place;

One protection tube, it is to be connected to above-mentioned joint inside, is formed with plural bulge loop on its surface, is formed with a depressed part between each bulge loop;

According to said structure, after above-mentioned protection tube was connected to joint body inside, the compressive plane of this forcing piece can force the intermediate plate clip in the depressed part of protection tube, can prevent that protection tube from getting loose.

Cooperate appended graphic explanation in detail below by specific embodiment, with the effect that is more prone to understand the purpose of this utility model, technology contents, characteristics and reached.

Embodiment

See also Fig. 1 and Fig. 2, shown is protection tube of the present utility model, joint, Cable structure decomposition and cross-sectional schematic.As shown in the figure: improved cable of the present utility model is fixed an integrated structure; include: a joint 1, one and the forcing piece 2 of described joint 1 winding; one with the protection tube 3 of described joint 1 and forcing piece 2 windings, have fixedly head of cable that protection is configured in protection tube 3 inside.

Above-mentioned mentioned joint 1 has a hollow body 11, has a blocking part 12 on this body 11, the

junction surface

13,14 that respectively has a flank on the body 11 of these 12 front and back, blocking part, engaged a locking part 15 on the described junction surface 13, after passing fixture 4 by described junction surface 13, utilize locking part 15 interlockings on junction surface 13, can be locked on the fixture 4 for joint 1; In addition, described another junction surface 14 front ends undertake plural rubber-like intermediate plate 16, have the clip portion 161 of colluding the angle on each intermediate plate 16, this intermediate plate 16 is sandwiched on the depressed part 32 of protection tube 2 the clip portion 161 on the intermediate plate 16 inwardly after being subjected to forcing piece 2 inner extruding against hook;

Its forcing piece 2 is a ducted body, its inside has a socket part 21 and that is flank and above-mentioned junction surface 14 and bores a hole 22, be formed with a compressive plane 23 that takes the form of inclined plane attitude between 22 places in socket part 21 and perforation, this compressive plane 23 can force above-mentioned intermediate plate 16 to be the recessed shape attitude and to clamp protection tube 3;

Protection tube 3 is a ducted body; be formed with plural bulge loop 31 on its surface; be formed with a depressed part 32 31 of each bulge loops; be connected to body 11 inside of joint 1 at protection tube 3 after; after forcing piece 2 is connected to joint 1 body 11; allow compressive plane 23 can force the clip portion 161 of intermediate plate 16 to be sandwiched on the depressed part 32 of protection tube 2 against hook inwardly, can prevent that protection tube 3 from getting loose.

See also Fig. 3 to Fig. 5, a fixing winding and the side of shown is Fig. 1 are analysed and observe the action schematic diagram.As shown in the figure: the utility model is when utilization, and elder generation utilizes locking part 15 interlockings on junction surface 13 after fixture 4 is passed at the junction surface 13 of the body 11 of joint 1, can be locked on the fixture 4 for joint 1;

After the body 11 of above-mentioned joint 1 is fixed in fixture 4; can earlier forcing piece 2 be connected on body 11 another junction surfaces 14; the not locking (intermediate plate 16 does not contact with compressive plane 23) as yet of forcing piece 2 this moment; protection tube 3 can be penetrated body 11 inside that are connected to joint 1 by the perforation 22 that chases after tight part 2; this moment with forcing piece 2 to the blocking part 12 of body 11 lock by the time; allow the compressive plane 23 of forcing piece 2 inside push each intermediate plate 16; allow each intermediate plate 16 be the recessed shape attitude; when intermediate plate 16 is the recessed shape attitude; clip portion 161 on this intermediate plate 16 promptly forms with external force reverse and inwardly catch on clip in the depressed part 32 of protection tube 3, can prevent that promptly protection tube 3 is subjected to strong external force factor and gets loose.

After above-mentioned joint 1, forcing piece 2 and protection tube 3 windings are finished; after again cable 5 being penetrated by body 11 other ends of joint 1; directly penetrate again in protection tube 3; when this moment, protection tube 3 was influenced by external force; this intermediate plate 16 can effectively be caught protection tube 3; can avoid protection tube 3 to get loose, to reach effective protection cable 5.
