Description

Technical Field

[0001] The utility model relates to the technical field of cable housings, in particular to a cable terminal housing. Background Art

[0002] The cable terminal connection housing is a key structural component of the GIS circuit breaker switchgear. In addition to the general functional uses required by the GIS, its main function is to install the terminals of the three-phase cables and connect the circuit to the circuit breaker, disconnector, earthing switch and other switchgear through the conductors installed in the housing. This connects the GIS switchgear to the external power supply line, thereby controlling the opening and closing of the entire transmission and distribution line.

[0003] Existing Chinese patent document CN201821751729.2 relates to a GIS compact composite cable terminal connection housing. The cable terminal connection housing includes: a main housing, an opening flange, a cable cone interface, a grounding switch interface, a double explosion-proof disk, an observation window, a grounding terminal, and a hanging ledge. The main housing adopts a nearly equilateral triangle structure. The opening flange is used to connect to the grounding switch device. The cable cone interface is located at the three vertices of the triangle of the main housing. The main housing is provided with a grounding switch interface for connecting to the grounding switch device. The main housing is provided with two symmetrically distributed explosion-proof disk structures for installing explosion-proof disks. The main housing is provided with two observation windows.

This utility model achieves a compact structure and composite functions, reducing the manufacturing cost and operation and maintenance costs of GIS switch equipment.

[0004] However, the above patent has certain defects when used. Since the cable generates heat during use and the cable shell is well sealed, the heat cannot be dissipated. Long-term use will affect the performance of the cable in the shell.

[0005] Therefore, a cable terminal housing is proposed to solve the above-mentioned problems. Utility Model Content

[0021] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 3 As shown, a cable terminal housing includes a cable housing 5, and the cable housing 5 includes a main body 51. The front end of the main body 51 is provided with a cable inlet 52, and the rear end is provided with a cable outlet. The main body 51 has a front cable inlet 52 and a rear end cable outlet for the connection and extraction of cables. A cable fixing structure can be provided inside the main body 51 as needed to ensure a stable connection of the cable. A heat dissipation housing 1 is provided on the outside of the cable housing 5. The heat dissipation housing 1 is a housing with openings at both ends and a hollow interior. The cable housing 5 is fixed inside the heat dissipation housing 1. The heat dissipation housing 1 is made of a material with good thermal conductivity to facilitate rapid transfer and dissipation of heat.

[0024] Access covers 2 are provided on the left and right sides of the heat dissipation housing 1. Each cover is provided with ventilation grilles 21 and is fixedly connected to the heat dissipation housing 1 via bolts 3. The ventilation grilles 21 allow air circulation, further enhancing the heat dissipation effect. The access covers 2 are fixedly connected to the heat dissipation housing 1 via bolts 3, allowing users to inspect and maintain internal cables and components without disassembling the entire housing.

[0025] A cooling fan 4 is provided inside the heat dissipation housing 1 and is fixed to an inner wall of the inspection cover 2. When the cooling fan 4 is working, it can accelerate the air exchange inside and outside the housing and significantly improve the heat dissipation efficiency.

[0026] A connecting rod 56 is provided on the lower surface of the main body 51. One end of the connecting rod 56 is fixedly connected to the main body 51, and the other end is provided with a mounting block 54. The mounting block 54 is provided with a fixing hole 55. The connecting rod 56 and the mounting block 54 are provided at the lower end of the main body 51 to facilitate fixing the cable terminal housing to the inside of the heat dissipation housing 1 by bolts 3 or other fasteners.

[0027] A plurality of heat dissipation grooves 53 are provided on the outer peripheral wall of the cable housing 5 . These heat dissipation grooves 53 can increase the surface area of the cable housing 5 , improve the heat dissipation effect, and further reduce the operating temperature of the cable.

[0028] The heat dissipation housing 1 is provided with a cable installation opening 11, which is symmetrically arranged on the front and back of the heat dissipation housing 1 and is connected to the interior. The design of the cable installation opening 11 facilitates the installation and insertion of cables, and can also be used for the access of other cables or sensors, thereby enhancing the scalability and practicality of the cable terminal housing.

[0029] The principle of use of the present invention is as follows: when in use, the cable is passed through the cable inlet 52 and outlet of the cable housing 5 and fixed inside the cable housing 5, and the cable terminal housing is fixed inside the heat dissipation housing 1 using the connecting rod 56 and the mounting block 54 to ensure overall stability;

[0030] When the cable transmits electrical energy, it generates a certain amount of heat. This heat is first absorbed by the cable housing 5 and then quickly transferred to the outside through the heat dissipation grooves 53. Since the heat dissipation grooves 53 increase the heat dissipation area, the heat dissipation is accelerated.

[0031] At the same time, the cooling fan 4 is started to accelerate the convection of air inside and outside the cooling housing 1, further improving the cooling effect and ensuring that the operating temperature of the cable remains within a safe range.

[0032] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
