Description

Cable joint structure

Technical Field

The utility model relates to a cable joint structure.

Background

The cable connector is also called a cable head. After the cable is laid, the sections of the cable must be connected together in order to form a continuous line, and these connections are called cable connectors. The cable joints at the middle of the cable run are called intermediate joints and the cable joints at the two ends of the run are called termination joints. The cable joint is used for locking and fixing the incoming and outgoing lines, and plays a role in water resistance, dust prevention and vibration prevention. However, the joint pipe fitting of the existing cable joint is generally provided with a connecting thread, and the lock nut at the end position is connected through the connecting thread, but in some use scenes, because the hanging distance of the lock nut is large, the thread at the end part can be exposed, so that during threading connection, the exposed threads are easy to damage cables when being bent, and the use effect of the whole structure is affected.

SUMMERY OF THE UTILITY MODEL

The utility model provides a cable joint structure, its simple structure, the connection effect is better, can not expose the tip screw thread, avoids pressing from both sides and hinders the cable.

In order to realize the above object, the utility model provides a cable joint structure, including connecting the pipe fitting, fastener and clamping piece down, it is the terrace with edge that the polygon set up to be formed with the cross-section on the pipe fitting to connect, it leads to the groove to be provided with the holding to connect pipe fitting cavity, it has the clamping sleeve to connect pipe fitting upper end screw-thread fit, the clamping piece sets up and installs in the logical groove of holding in connecting pipe fitting upper end and cooperation, the holding leads to and is provided with fastening thread on the groove lower extreme inner wall, fastener and fastening thread screw-thread fit down, fastener central point puts down and offers the through-hole that is used for supplying the cable to pass, the fastener still leads to the groove outward extension to have the retaining ring to the holding down, be provided with the packing ring between retaining ring and the terrace with edge.

The beneficial effect who sets up like this is, adopts above-mentioned scheme, sets up like this, changes the screw thread that connects body lower extreme into female thread structure, is connected through this fastening screw thread and fastener down simultaneously for joint pipe fitting lower extreme position can not expose the screw thread, and causes the clamp to hinder to the cable, and through retaining ring structure, can avoid the cable to walk the line to joint pipe fitting position simultaneously, and further avoid the cable to crush, and simple structure has good result of use simultaneously.

As a further setting of the utility model, the retaining ring lower extreme is the horn mouth setting, be connected through smooth curved surface between retaining ring and the lower fastener.

The beneficial effect who sets up like this is, adopts above-mentioned scheme, sets up like this and can avoid the connecting face of retaining ring and lower fastener to grind the cable, walks the line more smoothly, and simple structure has good result of use simultaneously.

As a further setting of the utility model, one of retaining ring orientation terrace with edge serves and is provided with a plurality of arc wall along circumference.

The beneficial effect who sets up like this is, adopts above-mentioned scheme, effectively reduces the weight of lower fastener to simple structure can effectively dispel the heat through the arc wall, improves overall structure's result of use.

As a further setting of the utility model, both ends are provided with the protruding muscle in location respectively about the packing ring, the protruding muscle in location is inconsistent with retaining ring and terrace with edge respectively.

The beneficial effect who sets up like this is, adopts above-mentioned scheme, guarantees the conflict of packing ring and retaining ring and terrace with edge, and difficult emergence is not hard up, reduces the wearing and tearing of packing ring simultaneously, guarantees the result of use.

Detailed Description

The first embodiment of the cable joint structure of the present invention is shown in fig. 1 to 2: including joint pipe fitting 1, lower fastener 3 and clamping piece 4, be formed with the terrace with edge 11 that the cross-section is the polygon setting on the joint pipe fitting, 1 cavity of joint pipe fitting is provided with and is formed with the holding and leads to the groove, 1 upper end screw-thread fit of joint pipe fitting has clamping sleeve 2, clamping piece 4 sets up and installs in the logical groove of holding in 1 upper end of joint pipe fitting and cooperation, the holding leads to and is provided with fastening thread on the groove lower extreme inner wall, fastener 3 and fastening thread screw-thread fit down, 3 central point of fastener puts down and offers the through-hole that is used for supplying the cable to pass, fastener 3 still leads to the groove extension outward to the holding down has retaining ring 31, be provided with packing ring 5 between retaining ring 31 and the terrace with edge 11. The beneficial effect who sets up like this is, adopts above-mentioned scheme, sets up like this, changes the screw thread that connects body lower extreme into female thread structure, is connected through this fastening screw thread and fastener 3 down simultaneously for 1 lower extreme position of joint pipe fitting can not expose the screw thread, and causes the clamp to hinder to the cable, simultaneously through retaining ring 31 structure, can avoid the cable to walk the line to 1 position of joint pipe fitting, and further avoid the cable to crush, and simple structure has good result of use simultaneously.

As a further configuration of the present embodiment, the lower end of the retainer ring 31 is flared, and the retainer ring 31 and the lower fastening member 3 are connected by a smooth curved surface. The beneficial effect who sets up like this is, adopts above-mentioned scheme, sets up like this and can avoid retaining ring 31 and fastener 3's connection face fraying cable down, walks the line more smoothly, and simple structure has good result of use simultaneously.
