Cable adapter

Technical Field

The utility model relates to the technical field of cables, specifically a cable adapter.

Background

Various large-scale equipment in a workshop needs to be connected with a power supply and data transmission by using cables. When the working condition in workshop is relatively poor, the protective sheath on cable surface receives the damage easily, for example cuts, corrodes etc.. Therefore, in order to prolong the service life of the cable, the rubber tube is sleeved on the cable, and meanwhile, when the end part of the cable is connected to the adapter, the end part of the rubber tube is fixed on the adapter.

The adapter is generally provided with a sleeve pipe, the rubber pipe is sleeved on the sleeve pipe through elastic deformation, and the rubber pipe is fixed on the sleeve pipe due to the elasticity of the rubber pipe, so that the rubber pipe is prevented from falling off from the adapter.

However, after long-time use, the end of the rubber tube is easy to deform, so that the rubber tube loses elasticity, falls off from the adapter and loses the protection effect on the cable.

Therefore, how to overcome the above-mentioned drawbacks becomes a problem to be solved urgently for those skilled in the art.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem in the background art, the utility model discloses a cable adapter.

The utility model provides a cable adapter, including the body, body one end is equipped with:

the connecting seat is clamped on the body and provided with an inner hole for the cable to pass through; an annular clamping groove is formed in the outer side of the inner hole, and the rubber tube is inserted into the clamping groove; the elastic snap ring is sleeved outside the rubber tube; and the nut is in threaded connection with the body, and when the nut is locked, the clamping ring is driven to deform, so that the rubber tube is clamped between the clamping ring and the inner wall of the clamping groove.

The clamping groove is used for mounting and positioning the rubber tube; the rubber tube is fixed in a clamping mode of the clamping ring and the connecting seat, and compared with a traditional rubber tube installation mode, the rubber tube is more stable after being installed and is not easy to fall off; and when the rubber tube is installed, the rubber tube is in clearance fit with the connecting seat and the clamping ring, so that the rubber tube is convenient to disassemble and assemble.

The concrete structure of the connecting seat is as follows: the connecting seat comprises an inner pipe and an outer pipe which are sequentially arranged from inside to outside, the inner pipe and the outer pipe are coaxially arranged, and one ends of the inner pipe and the outer pipe are integrally formed and connected through a connecting sheet; the inner hole is arranged on the inner tube; the inner pipe, the outer pipe and the connecting sheet form a clamping groove.

The concrete clamping structure of the connecting seat and the body is as follows: the other end of the outer pipe is in a flaring shape; the end of the connecting seat provided with the connecting sheet is inserted into the body, and the flaring end of the outer pipe is abutted against the end part of the body, so that clamping is realized. The arrangement of the flaring can play a role in guiding the splicing of the rubber tube, thereby facilitating the splicing and installation of the rubber tube.

The snap ring is annular and is not easy to deform, so that the problem is further solved by improvement, and specifically, the snap ring is provided with a notch. The elasticity of snap ring has not only been improved to the setting of breach, has still improved the deformability of snap ring to be convenient for press from both sides tight rubber tube.

The specific structure that nut drive snap ring deformation does: one end of the clamping ring is provided with a first chamfer, and the chamfer surface of the first chamfer abuts against the inner wall of the flared end of the outer pipe. When the nut extrudees the snap ring, first chamfer plays the guide effect to make the snap ring shrink, the diameter diminishes, extrudees fixedly to the rubber tube.

Further, a second chamfer is arranged at the other end of the clamping ring; the outer end of the nut is provided with a convex plate protruding inwards, and the convex plate abuts against the second chamfer. So set up, when the nut extrudeed the snap ring, the snap ring was changeed deformation under the effect of second chamfer and flange.

The outer wall of the inner pipe is generally a smooth surface, so that the clamping force on the rubber pipe is small, the problem is further solved by improvement, and specifically, the outer wall of the inner pipe is provided with a convex strip. The arrangement of the convex strips shortens the distance between the inner pipe and the clamping ring, thereby improving the clamping force of the rubber pipe.

The setting of sand grip has improved the processing degree of difficulty of snap ring, so further improve and solve this problem, and is concrete, and inner tube wall is equipped with the recess that corresponds the sand grip to make sand grip and recess pass through extrusion.

Because the coverage area of the convex strip is smaller, the design is further as follows based on the coverage area: the raised lines and the grooves are both spiral.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 4, the present invention relates to a cable adapter, which comprises a hollow body 1, one end of which is connected with a connecting seat 2, a snap ring 3 and a nut 4.

As shown in fig. 3, the connecting seat 2 includes an inner tube 23 and an outer tube 24 sequentially arranged from inside to outside, the inner tube 23 and the outer tube 24 are coaxially arranged, one end of the inner tube is flush and integrally connected through a connecting piece 25, and the connecting part is in arc transition. The inner tube 23 is provided with an inner bore 21 for the passage of a cable. The outer tube 24 is shorter in length than the inner tube 23. The inner tube 23, the outer tube 24 and the connecting piece 25 constitute a catch 22. The rubber tube is inserted in the clamping groove 22 to realize installation and positioning. The other end of the inner tube 24 is also provided with an inner folded edge to avoid scratching when the cable is inserted.

The other end of the outer tube 24 is flared and has an arc-shaped cross section. The one end that connects seat 2 to be equipped with connection piece 25 is pegged graft in body 1, and the flaring end of outer tube 24 supports and leans on body 1 tip, realizes the joint. Due to the arrangement of the flaring, the rubber pipe can be guided to be inserted and installed conveniently.

The snap ring 3 is annular, is a metal part, and has elasticity. And snap ring 3 still is equipped with the breach, and the breach has not only improved snap ring 3's elasticity, has still improved snap ring 3's deformability to be convenient for press from both sides tight rubber tube.

As shown in fig. 2, one end of the snap ring 3 is provided with a first chamfer 31, which is an outer chamfer, the chamfer surface of which abuts against the inner wall of the flared end of the outer tube 24.

The nut 4 is connected with the body 1 by screw thread, and the outer end of the nut is provided with a convex plate 41 which is convex inwards. When the nut 4 is locked, the convex plate 41 extrudes the clamping ring 3, the clamping ring 3 contracts under the guiding action of the first chamfer 31, the diameter is reduced, and therefore the rubber pipe is extruded to be fixed.

The rubber tube is fixed in a clamping mode of the clamping ring 3 and the connecting seat 2, and compared with a traditional rubber tube installation mode, the rubber tube is more stable after being installed and is not easy to fall off; and when the rubber tube is installed, the rubber tube is in clearance fit with the connecting seat 2 and the clamping ring 3, so that the rubber tube is convenient to disassemble and assemble.

Example two:

So set up, when nut 4 locks, flange 41 not only extrudees snap ring 3, still orders about snap ring 3 shrink to make snap ring 3 change shape more.

Example three:

compared with the first embodiment, the differences are as follows: as shown in fig. 4, the outer wall of the inner tube 23 is provided with ribs 26. The arrangement of the convex strip 26 shortens the distance between the inner pipe 23 and the snap ring 3, thereby improving the clamping force of the rubber pipe.

Example four:

compared with the three phases of the embodiment, the differences are as follows: the inner wall of the inner tube 23 is provided with grooves 27 corresponding to the ribs 26, so that the ribs 26 and the grooves 27 are formed by extrusion. With this arrangement, the processing of the convex strips 26 is simplified, thereby reducing the cost.

Example five:

compared with the fourth embodiment, the differences are as follows: the ridges 26 and grooves 27 are both helical. So set up, not only increased the scope that the sand grip 26 covered the rubber tube, the rubber tube in the sand grip 26 scope all receives the extrusion of sand grip 26 moreover to make the rubber tube installation more firm, be difficult for droing.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention.
