The refrigeration compressor connector is a device used to connect the refrigeration compressor with other components. It can realize the electrical connection and signal transmission between the various components in the refrigeration system. There are many types of refrigeration compressor connectors, and the common ones are terminal posts, plugs, sockets, etc. These connectors are usually made of metal or plastic, with good conductivity and insulation properties, which can ensure the normal operation of the refrigeration system.

[0003] Prior art, such as the utility model with publication number CN214254882U, discloses a quick-plug connector for a refrigeration compressor. The patent adopts a connector, the outer surface of which is provided with a protrusion, and an external end of the connector is provided with a plug port, and one end of the plug port is provided with a magnetic suction cup, one end of the magnetic suction cup is fixedly connected to the end of the connector, and the end of the magnetic suction cup away from the connector is fixedly connected to a plug, and a pin is provided inside the plug. The utility model is provided with a magnetic suction cup, and the magnetic suction cup is located at the rear of the plug port and the front of the plug port. A plug is provided at the end, and the magnetic suction cup is magnetically connected to the metal device at the connection end, so that the plug and the pins inside the plug can be quickly attracted and connected with the connector, realizing the quick plug-in processing of the connector, which not only facilitates the operator's plug-in work of the connector, but also improves the plug-in efficiency of the connector, and solves the problems that the existing refrigeration compressor connector cannot complete the plug-in processing quickly and easily when connecting between working devices, the insulation performance and pressure resistance of the connecting line are not good enough, and the line body is prone to entanglement and confusion during the connection process.

[0004] The inventor has discovered in his daily work that in the process of using a connector to connect a refrigeration compressor and a working device, there are existing connectors such as the above-mentioned ones. In order to meet the use requirements, the connecting wire adopts a multi-layer structure design to protect the innermost wire core and improve the resistance and strength of the wire core. The connecting wire using the multi-layer structure design has better resistance to electromagnetic waves, but the plug part has poor shielding effect against electromagnetic waves due to structural design problems, resulting in that when the plug is inserted into the socket, the connection part between the plug and the socket is easily interfered by external electromagnetic waves, thereby causing the plug to fluctuate during use. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the plug part in the prior art has a poor shielding effect on electromagnetic waves due to the structural design problem, so that when the plug is inserted into the socket, the connection part between the plug and the socket is easily interfered by external electromagnetic waves, thereby causing the plug to fluctuate during use. A shielding cover for a refrigeration compressor connector is proposed to solve the problem that the plug part has a poor shielding effect on electromagnetic waves due to the structural design problem, so that when the plug is inserted into the socket, the connection part between the plug and the socket is easily interfered by external electromagnetic waves, thereby causing the plug to fluctuate during use.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a shielding cover for a refrigeration compressor connector, comprising a connecting cable, a connecting plug and a shielding assembly, wherein the connecting plug is fixed at the output end of the connecting cable, and the shielding assembly is arranged at the junction of the connecting plug and the connecting cable;

The outer circumference of the positioning clamping ring is threadedly connected with a fastening sleeve, and the outer circumference of the protective shell is threadedly connected with a constraining threaded sleeve.

[0009] Preferably, there are two limit frames, which are symmetrically arranged with respect to the connecting cable. The limit frames are U-shaped. The limit frames installed on the outside of the connecting ring can cooperate with the rotating shaft to support the position of the connecting plate, and at the same time, the rotation axis of the connecting plate can be determined to improve the stability of the connecting plate during rotation.

[0010] Preferably, the connecting plate abuts against the inner wall of the limit frame, the length of the connecting plate is greater than the height of the limit frame, and the upper surface of the connecting plate is arc-shaped. By installing the connecting plate inside the limit frame, the connecting plate can cooperate with the limit frame and the rotating shaft to guide the moving direction of the assembly ring during rotation.

[0011] Preferably, the assembly ring abuts against the outer circumference of the connecting ring, and there are two assembly rings, which are symmetrically arranged with respect to the connecting ring.

[0012] Preferably, there are two shielding covers, which are symmetrically arranged with respect to the connecting plug. By arranging shielding covers on both sides of the connecting plug, external electromagnetic waves can be shielded when the connecting plug is in the plugged state, so as to improve the stability of the connecting plug during use.

[0013] Preferably, there are two protective shells, which are symmetrically arranged with respect to the connecting plug. The shielding cover can be protected from the outside by the protective shells, thereby improving the protective effect of the shielding cover against external objects.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:
