Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, specifically a cable connector structure. Background Technology

[0002] In power transmission and distribution, communication systems and various industrial equipment, cables are assemblies composed of one or more insulated cores, with insulation, protective layers and outer sheaths, used to transmit electrical energy, signals or data.

[0003] Currently, to make two cable segments a continuous line, these connection points need to be insulated and sealed. The conventional method is to remove the protective sheaths at opposite ends of the two cables, then weld the wire cores with flux, cool them with a fan, grind them with a grinder, wrap them with semi-conductive self-adhesive tape and insulating vulcanizing tape, then cover them with cold shrink tubing, and subsequently wrap them with tin foil, plastic wrap (for even heating), yellow tape (for even heating), heating tape (for insulation), and cotton cloth (to enhance insulation). Then, heat them again, cool them down, and remove the cold shrink tubing, tin foil, plastic wrap, yellow tape, heating tape, and cotton cloth. Then grind them, apply semi-conductive paint and tape, cover them with a shielding mesh, and finally wrap multiple cable conductors with PVC tape. The operation process is complicated, and when one set of conductors is hot, it can affect other conductors. Therefore, a cable joint structure is proposed. Utility Model Content

[0004] Based on the above description, this utility model provides a cable connector structure that solves the technical problems pointed out in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a cable joint structure for completing the docking and protection of two sets of cable bodies, wherein the cable body has multiple cable conductors, and the cable joint structure further includes a central sleeve structure and two sets of docking clamp structures. The central sleeve structure includes an inner sleeve, an outer sleeve fixed to the outer side of the middle part of the inner sleeve, and multiple conductor blocks fixed to the inner side of the inner sleeve. The docking jacket structure includes a docking sleeve, which is detachably disposed on the outside of the inner sleeve. An insulating support is fixed inside the docking sleeve. A conductive frame is fixed on the opposite side of the insulating support in both sets of docking jacket structures. The conductive frame has a support cavity for accommodating the cable conductor. An elastic pressure plate is provided at the support cavity, which can move closer to or further away from each other. The elastic pressure plate presses and limits the cable conductor.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the number of conductor blocks, cable conductors, and conductive frames are equal, and the number of cable conductors is four sets.

When the central sleeve structure and the butt sleeve structure are not separated, the conductor block is attached to the outside of the extended conductive block.

[0009] Furthermore, both ends of the outer sleeve are provided with docking cavities, which consist of a circular cavity and a rectangular cavity. Several protrusions arranged in a circumferential array are provided on the inner wall of the circular cavity. Each of the two docking sleeves has a docking block fixed on its opposite side, and the docking block is adapted to the docking cavity.

[0010] Furthermore, a docking plate is fixed to the outer side of the docking sleeve, and a locking bolt is threaded between the docking plate and the outer sleeve.

[0011] Furthermore, it also includes a sealing ring, with grooves provided on the opposite sides of the mating plate and the outer sleeve, and the sealing ring is pressed between the two grooves.

[0012] Furthermore, the inner side of the mating sleeve is provided with a through hole for the cable body to pass through.

[0013] Furthermore, an extension block is fixed on the side of the coupling sleeve away from the outer sleeve. A through hole is opened on the inner side of the extension block, and the diameter of the through hole is equal to that of the through hole. A limiting bolt for pressing against the cable body is threaded on the extension block.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This cable joint structure features a conductive frame that limits the cable conductors. By combining the docking jacket structure with the central sleeve structure, the connection between the two sets of cable bodies can be completed. The operation process is simple.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1 As shown, this embodiment of the cable joint structure is used to connect and protect two sets of cable bodies 1. The cable body 1 has multiple cable conductors 11. Exemplarily, the number of cable conductors 11 is, for example, four sets. The cable joint structure includes a central sleeve structure 2 and two sets of docking clamp structures 3.

[0019] And such Figure 1-4 As shown, the central sleeve structure 2 includes an inner sleeve 21, an outer sleeve 22 with a regular hexagonal cross-section is fixed on the outer side of the middle part of the inner sleeve 21, and a conductor block 24 is fixed on the inner side of the inner sleeve 21. The conductor block 24 is a relay structure for electrical connection, and the number of conductor blocks 24 is equal to the number of cable conductors 11.

[0020] As for the docking jacket structure 3, it includes a docking sleeve 31. The docking sleeve 31 is detachably set and located outside the inner sleeve 21. A through hole is opened on the inner side of the docking sleeve 31 for the cable body 1 to pass through. An insulating support 32 is fixed inside the docking sleeve 31. On the opposite side of the insulating support 32 in the two sets of docking jacket structures 3, multiple sets of conductive frames 33 are fixed. In fact, their number is the same as the number of cable conductors 11. For example, the number of conductive frames 33 is four sets. The conductive frame 33 has a resting cavity for the cable conductor 11 to be accommodated. An elastic pressure plate 34 that can move closer and further away from each other is provided in the resting cavity. After the cable conductor 11 is accommodated in the resting cavity, the elastic pressure plate 34 presses and limits the cable conductor 11.

[0021] It should be noted that the conductive frame 33 consists of a conductive plate 331 and two sets of extended conductive blocks 332. There is a gap between the two sets of extended conductive blocks 332 for the cable conductor 11 to pass through. When the central sleeve structure 2 and the docking jacket structure 3 are not separated, the conductor block 24 is attached to the outside of the extended conductive block 332. It can be understood that, in order to strengthen the fixing effect, the cable conductor 11 can be temporarily limited by the elastic pressure plate 34 before welding the conductive plate 331.

[0022] Additionally, it should be noted that, to restrict rotation between the mating sleeve structure 3 and the central sleeve structure 2, both ends of the outer sleeve 22 are provided with mating cavities 23. Each mating cavity 23 consists of a circular cavity and a rectangular cavity. The inner wall of the circular cavity has several protrusions arranged in a circumferential array. Correspondingly, with... Figure 1 From a perspective, each of the two mating sleeves 31 has a mating block 35 fixed on one side facing each other. The mating block 35 is adapted to the mating cavity 23. In this way, the mating positioning between the mating sleeve structure 3 and the central sleeve structure 2 can be achieved through the rectangular cavity. The protrusion in the circular cavity and the rectangular cavity restrict the rotation between the mating sleeve structure 3 and the central sleeve structure 2.

[0023] Regarding the fixing of the docking sleeve structure 3 and the central sleeve structure 2, a docking plate 36 is fixed to the outside of the docking sleeve 31, and a locking bolt is threaded between the docking plate 36 and the outer sleeve 22.

[0024] Furthermore, to enhance the sealing, the cable joint structure also includes a sealing ring 37. The sealing ring 37 is made of rubber or silicone, which has good elasticity and weather resistance. It is used to prevent moisture, dust and other substances from entering the interior of the joint and improve the protection level. Grooves are provided on the opposite sides of the mating plate 36 and the outer sleeve 22, and the sealing ring 37 is squeezed between the two grooves.

[0025] To limit the cable body 1, an extension block 38 with a regular hexagonal cross-section is fixed on the side of the mating sleeve 31 away from the outer sleeve 22. The extension block 38 has a through hole on its inner side, which is the same size as the through hole, for the cable body 1 to pass through. A limiting bolt 39 for pressing the cable body 1 is threaded on the extension block 38. In this way, the cable body 1 is limited and prevented from being pulled out or loosened during operation.

[0026] Insert the cable body 1 through the through hole of the mating sleeve 31, and then insert each cable conductor 11 into the placement cavity of the corresponding conductive frame 33. The structure of this cable connector is described below: The cable conductor 11 is initially fixed by pressing the elastic pressure plate 34. The docking block 35 of the docking jacket structure 3 is inserted into the docking cavity 23 of the central sleeve structure 2. The rectangular cavity achieves initial positioning. The docking plate 36 is fixed to the outer jacket 22 by using locking bolts. The limiting bolt 39 is tightened to press the outer layer of the cable body 1, thus achieving mechanical fixation. The docking between the two sets of cable bodies 1 is simple to operate. In addition, the two sets of corresponding cable conductors 11 between the two sets of cable bodies 1 are spaced apart and independently limited and conducted. When any set of cable conductors 11 is at high temperature, it is not easy to affect other cable conductors 11.

[0027] Sealing protection description: The sealing ring 37 forms a compression seal between the mating plate 36 and the outer sleeve 22 to prevent the intrusion of external media.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
