Technical Field

[0001] This utility model relates to the field of cable terminal plug fixing, and in particular to a 10kV cable terminal plug insulation fixing device. Background Technology

[0002] A 10kV cable terminal plug refers to an electrical connection component installed on a 10kV cable terminal. It is mainly used to connect cables to power distribution equipment, ensuring the stability and safety of power transmission. Testing of 10kV elbow cable heads can ensure the quality and performance of elbow cable heads, guarantee the safety and reliability of power transmission, promptly detect and eliminate potential hazards, and extend the service life of elbow cable heads.

[0003] When fixing 10kV cable terminal plugs, with the increasing scale and miniaturization of power grid equipment, traditional testing tools are gradually being phased out due to insufficient insulation and complex operation. In addition, during the connection process, the conductor is prone to falling off due to external force, resulting in unstable connection. To address this, we propose an insulation fixing device for 10kV cable terminal plugs. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figure 1-6 An insulating fixing device for a 10kV cable terminal plug includes an elbow-shaped head 2. An insulating plug 1 is fitted on one side of the elbow-shaped head 2, and a conductor 4 is embedded on the other side of the elbow-shaped head 2. An insulator 3 is embedded on the surface of the conductor 4 on one side of the elbow-shaped head 2. A clamping structure 5 is fixedly connected between the insulating plug 1 and the insulator 3. The insulating plug 1 is an insulating nut with a base. Both the insulating plug 1 and the insulating cover 301 are polysiloxane elastomers and are insulating materials. The elbow-shaped head 2 has good insulation performance to prevent partial discharge and insulation breakdown. The conductor 4 has an internal elastic "banana plug" conductor. It uses a spring structure to adapt to different terminal sizes, increase the contact area, and reduce the contact resistance. The "banana plug" increases the contact stability of the terminal. The outer side uses a uniform specification terminal block. With the help of a plug-type insulated connection cable, it can greatly ensure the stability of the connection line and ensure wiring safety.

[0024] In a preferred embodiment, the insulator 3 includes an insulating cover 301, a first insulating screw 302, a slider 303, a groove 304, and an insert block 305. A groove 304 is formed on one side surface of the insulating cover 301. The slider 303 is embedded in the groove 304. The slider 303 is fixed to the insulating cover 301 by the first insulating screw 302. An insert block 305 is fixedly installed on one side surface of the slider 303.

[0025] In a preferred embodiment, the conductor 4 includes a copper-plated steel guide rod 401, a threaded guide rod 402, and an embedding groove 403. The threaded guide rod 402 is fixedly installed on one side surface of the copper-plated steel guide rod 401. The embedding groove 403 is formed on the side of the copper-plated steel guide rod 401 away from the threaded guide rod 402. The copper-plated steel guide rod 401 is shallow and is only used to limit the embedding block 305, and will not affect the normal use of the conductor 4.

[0026] In a preferred embodiment, the insulating plug 1 and the copper-plated steel guide rod 401 are both embedded inside the elbow head 2. The threaded guide rod 402 is embedded inside the insulating plug 1. The insulating cover 301 is sleeved on the surface of the copper-plated steel guide rod 401. The embedding block 305 is embedded inside the embedding groove 403. The threaded guide rod 402 and the insulating plug 1 are connected by threads. The sliding groove 304 has a screw hole inside, which is used to fix the slider 303 and the insulating cover 301 by the first insulating screw 302. The slider 303 can slide inside the sliding groove 304, but will not detach from the sliding groove 304. Its position is limited by the first insulating screw 302, thereby limiting the position of the embedding block 305. The insulating plug 1 and the insulating cover 301 are distinguished by color code (red, yellow, green) to distinguish the phase sequence. Combined with the socket foolproof design, the wiring accuracy is ensured to be 100%.

[0027] In a preferred embodiment, the clamping structure 5 includes a connecting plate 501, a connecting rod 502, a threaded groove 503, and a third insulating screw 504. There are two sets of connecting plates 501, and the connecting rod 502 is embedded between the connecting plates 501. Threaded grooves 503 are opened on both sides of the connecting rod 502, and the third insulating screw 504 is embedded in the threaded groove 503. The threaded groove 503 and the third insulating screw 504 are fixed by threaded connection.

[0028] In a preferred embodiment, the connecting plate 501 is fixedly installed on the lower surfaces of the insulating plug 1 and the insulating cover 301, respectively.

[0029] It should be noted that during use, the insulating plug 1 and the copper-plated steel guide rod 401 are respectively embedded into the two ends of the elbow head 2, so that the threaded guide rod 402 is embedded into the interior of the insulating plug 1 for fixation. The embedding block 305 is embedded into the interior of the embedding groove 403, and the slider 303 is fixed to the insulating cover 301 by the first insulating screw 302. The connecting rod 502 is embedded between the connecting plates 501, and the third insulating screw 504 is embedded into the interior of the threaded groove 503 for fixation, thereby achieving the purpose of good insulation and stable connection.
