Description

Technical Field

[0001] This utility model belongs to the field of distribution box technology, specifically relating to a smart adapter for cable grounding in electrical distribution boxes. Background Technology

[0002] In modern power distribution systems, electrical distribution boxes are an indispensable and important component. They undertake the critical task of distributing electrical energy from the power grid to various electrical devices, and are also responsible for controlling, protecting, and monitoring circuits to ensure the safe and stable operation of the power system. Whether it is large-scale machinery and automated production lines in industrial production, lighting systems and elevators in commercial buildings, or various electrical appliances in residential homes, all rely on distribution boxes to provide a reliable power supply. For example, in factory workshops, the normal operation of distribution boxes is directly related to whether production equipment can continue to work. Once a distribution box malfunctions, it may lead to the interruption of the entire production process, causing huge economic losses.

[0003] Existing cable adapters have relatively fixed models and can only connect to a single type of cable. When the cable model is incompatible, the adapter needs to be replaced, which greatly affects the user experience and the applicability of the adapter. Therefore, a smart cable grounding adapter for electrical distribution boxes is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent adapter for cable grounding in electrical distribution boxes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent adapter for cable grounding in an electrical distribution box, comprising an expansion threaded sleeve, a fixing nut threaded on the outer side of the expansion threaded sleeve, a sealing sleeve on the inner side of the expansion threaded sleeve, a heat-conducting block on one side of the expansion threaded sleeve, a connecting groove on the inner side of the heat-conducting block, heat dissipation fins on the outer side of the heat-conducting block, an elastic clamp on one side of the fixing nut, and a ventilation mesh on the outer side of the heat-conducting block through a groove.

[0006] In a preferred embodiment, the sealing sleeve is made of natural rubber and is tightly fitted to the inner wall of the expansion threaded sleeve.

[0007] In a preferred embodiment, the fixing nut is frustum-shaped, and the inner wall of the fixing nut is connected to the expansion threaded sleeve by threads.

[0008] In a preferred embodiment, the number of elastic clamps is six, the six elastic clamps are arranged in a frustum shape, and no two elastic clamps are connected to each other, and the inner walls of the six elastic clamps are threaded.

[0009] In a preferred embodiment, the number of heat dissipation fins is several, the ventilation mesh is located on the outside of the heat dissipation fins, and the connecting groove is inverted bucket shape.

[0010] In a preferred embodiment, a connecting joint is provided on one side of the connecting groove, and a sealing ring is provided on the inner side of the fixing nut. The sealing ring is made of natural rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a combination of an expansion threaded sleeve, a fixing nut, and an elastic clamp to securely install cables of different models onto the connector, greatly improving the applicability of the equipment and reducing the manufacturing cost of the adapter. The cooperation of the expansion threaded sleeve and the fixing nut secures the cable inserted into the expansion threaded sleeve. The design of the elastic clamp, sealing sleeve, and sealing ring seals the connection between the cable and the inner wall of the expansion threaded sleeve and the fixing nut, preventing external dust and moisture from entering the adapter and affecting its use.

[0013] This invention features a sealing sleeve and a sealing ring made of natural rubber, which have high elasticity. This allows the sealing sleeve and sealing ring to fit tightly against the outside of the cable, thus providing a better seal. The heat dissipation fins and heat-conducting blocks can quickly dissipate heat at the connection between the cable and the connector, improving the service life of the adapter. The ventilation mesh prevents dust from adhering to the heat dissipation fins and affecting their performance. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-4 This utility model provides an intelligent adapter for cable grounding in electrical distribution boxes, including an expansion threaded sleeve 1. A fixing nut 2 is provided on the outer side of the expansion threaded sleeve 1 via threads. A sealing sleeve 3 is provided on the inner side of the expansion threaded sleeve 1. A heat-conducting block 4 is provided on one side of the expansion threaded sleeve 1. A connecting groove 5 is opened on the inner side of the heat-conducting block 4. A heat dissipation fin 6 is provided on the outer side of the heat-conducting block 4. An elastic clamp 7 is provided on one side of the fixing nut 2. A ventilation mesh 8 is provided on the outer side of the heat-conducting block 4 via a groove. In use, the cable is inserted into the expansion threaded sleeve 1, and then the frustum-shaped fixing nut 2 and the elastic clamp 7 are tightened by threads to fix the cable in place.

[0022] The sealing sleeve 3 is made of natural rubber and is tightly attached to the inner wall of the expansion threaded sleeve 1.

[0023] The fixing nut 2 is frustum-shaped, and the inner wall of the fixing nut 2 is connected to the expansion threaded sleeve 1 by threads.

[0024] There are six elastic clamps 7, which are arranged in a frustum shape. No two elastic clamps 7 are connected to each other. The inner walls of the six elastic clamps 7 are threaded.

[0025] There are several heat dissipation fins 6, the ventilation mesh 8 is located on the outside of the heat dissipation fins 6, and the connecting groove 5 is inverted bucket shape.

[0026] A connecting joint 9 is provided on one side of the connecting groove 5, and a sealing ring 10 is provided on the inner side of the fixing nut 2.
