Description

Technical Field

[0001] This utility model relates to the field of cable termination technology, and in particular to a cable termination installation structure. Background Technology

[0002] With the rapid development of modern society, electricity, as an important energy source, has been widely used in various fields. As a key carrier of electricity transmission, the reliability of cable connections is crucial, and cable terminations are key components for connecting cables to other electrical equipment.

[0003] In existing cable termination installation methods, the connection between the cable and the cable termination is mostly achieved by splicing the two together and then covering the outside with heat shrink tubing. However, this method is not effective in resisting external forces and is prone to loosening. Once the connection is loose, the contact resistance increases, leading to electrical faults such as overheating and arcing, seriously affecting the stability and safety of power transmission. Furthermore, the sealing effect cannot be guaranteed during installation, allowing external moisture, dust, and other impurities to easily penetrate into the cable termination, which gradually degrades the insulation performance and affects its usability. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of unstable installation and poor sealing effect of cable termination heads in the prior art, and to propose a cable termination head installation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable termination installation structure includes a cable termination body, a cable branch installed on one end of the cable termination body, an installation groove formed on the bottom surface of the cable termination body, a detachable cable body being snapped into the installation groove, and a sealing groove formed on the bottom surface of the cable termination body, a sealing ring being snapped into the sealing groove.

[0007] Also includes:

[0008] Fasteners that facilitate the secure installation of the cable body to the cable terminal body.

[0009] Preferably, the fastener comprises:

[0010] Concave blocks are symmetrically fixed on both side walls of the cable terminal head body;

[0011] A rotating rod, which is rotatably connected within the concave block;

[0012] A sleeve, which is fixedly fitted onto the rotating rod;

[0013] A locking rod, which is fixed to the sleeve;

[0014] A screw groove is formed on the snap-fit ​​rod;

[0015] Nut, which is fitted onto the snap-fit ​​rod.

[0016] Preferably, the fastener further includes:

[0017] A collar, which is fixedly sleeved on the cable body;

[0018] The fixing blocks are symmetrically fixed on both sides of the collar;

[0019] The U-shaped groove is formed within the fixed block;

[0020] An abutment groove is formed on the bottom surface of the fixing block.

[0021] Preferably, the nut has an external thread that mates with the threaded groove, and the outer contour of the nut matches the inner contour of the abutment groove.

[0022] Preferably, the collar is fitted to the bottom surface of the cable terminal head body, and the locking rod is engaged with the U-shaped groove.

[0023] Preferably, the sealing ring is fixedly connected to the collar.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. In this utility model, the cable and cable terminal head are initially positioned by snapping together through the mounting groove, and then fastened with fasteners. The design of the fasteners makes the connection between the cable body and the cable terminal head body more secure, which can effectively prevent the connection from loosening due to vibration, electromagnetic force and other factors during power transmission, and ensure the stability of the electrical connection. Compared with the traditional cable terminal head installation method, it reduces complicated operation steps, lowers the requirements for the professional skills of construction personnel, and improves installation efficiency.

[0026] 2. This utility model adds a sealing ring, which can be evenly compressed during cable fastening and installation to form a good sealing effect. This sealing structure can not only effectively prevent the intrusion of external moisture, dust, etc., but also, during long-term use, because the collar fits tightly against the bottom surface of the cable terminal head, it can better adapt to environmental changes, reduce the problem of insulation performance degradation caused by poor sealing, and extend the service life of the cable terminal head.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figures 1-4 A cable termination installation structure includes a cable termination body 1, a cable branch 2 installed on the end side of the cable termination body 1, an installation groove 3 opened on the bottom surface of the cable termination body 1, a detachable cable body 4 snapped into the installation groove 3, and a sealing groove 5 opened on the bottom surface of the cable termination body 1, a sealing ring 6 snapped into the sealing groove 5.

[0035] A cable termination mounting structure also includes fasteners, which facilitate the fastening of the cable body 4 to the cable termination body 1.

[0036] The fasteners include a concave block 31, a rotating rod 32, a sleeve 33, a snap-fit ​​rod 34, a screw groove 35, a nut 36, a collar 41, a fixing block 42, a U-shaped groove 43, and an abutment groove 44. The concave block 31 is symmetrically fixed on the two side walls of the cable terminal head body 1. The rotating rod 32 is rotatably connected inside the concave block 31. The sleeve 33 is fixedly sleeved on the rotating rod 32. The snap-fit ​​rod 34 is fixed on the sleeve 33. The screw groove 35 is opened on the snap-fit ​​rod 34. The nut 36 is sleeved on the snap-fit ​​rod 34. The collar 41 is fixedly sleeved on the cable body 4. The fixing block 42 is symmetrically fixed on both sides of the collar 41. The U-shaped groove 43 is opened inside the fixing block 42. The abutment groove 44 is opened on the bottom surface of the fixing block 42. The size and shape of the concave block 31 are designed according to the diameter and length of the rotating rod 32 to ensure that the rotating rod 32 can rotate flexibly within the concave block 31. At the same time, the concave block 31 should have sufficient strength and stability to support the weight and force of the rotating rod 32 and subsequent connecting parts.

[0037] The nut 36 has an internal external thread that mates with the threaded groove 35, and the outer contour of the nut 36 matches the inner contour of the abutment groove 44. The pitch and depth of the threaded groove 35 precisely match the internal thread of the nut 36 to ensure that the nut 36 can be smoothly screwed in and out of the locking rod 34 and to provide sufficient tightening force after tightening. The material of the nut 36 should be compatible with the locking rod 34 to prevent corrosion or seizing during long-term use.

[0038] The collar 41 is attached to the bottom surface of the cable terminal head body 1, and the locking rod 34 is locked into the U-shaped groove 43.

[0039] The sealing ring 6 is fixedly connected to the collar 41. The material of the sealing ring 6 has good elasticity, aging resistance, and weather resistance. For example, the silicone rubber sealing ring 6 can maintain good elasticity over a wide temperature range, effectively resisting the erosion of environmental factors such as ultraviolet rays and ozone, and ensuring long-term stable sealing performance.

[0040] The functional principle of this utility model can be explained through the following operation methods:

[0041] When installing and using the cable terminal head, first align the cable body 4 with the mounting groove 3 at the bottom of the cable terminal head and snap it in place to achieve initial positioning of the cable and the cable terminal head body 1. At this time, the sealing ring 6 is squeezed into the sealing groove 5, filling the gap between the cable terminal head body 1 and the cable, thus playing a sealing role and preventing moisture, dust and other impurities from entering the inside of the cable terminal head and affecting its electrical performance.

[0042] During the initial clamping, the collar 41 is in contact with the bottom surface of the cable body 4. Then, by rotating the rotating rod 32, the sleeve 33 fixed on it is rotated, which in turn causes the clamping rod 34 fixed on the sleeve 33 to rotate. During the rotation, the clamping rod 34 enters the U-shaped groove 43 on the fixing block 42. When the clamping rod 34 rotates to the appropriate position, it is in a vertical state. Then, the nut 36 is sleeved on the clamping rod 34. By rotating the nut 36, it rotates upward along the threaded groove 35 on the clamping rod 34. When the nut 36 moves to the abutment groove 44, the nut 36 is embedded in the abutment groove 44, thereby tightly connecting the fixing block 42 and the clamping rod 34, realizing the fastening installation of the cable body 4 and the cable terminal head body 1.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
