Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration compressors, in particular to a refrigeration compressor connector which is easy to seal. Background Art

[0002] The refrigeration compressor is the core and heart of the refrigeration system. The capacity and characteristics of the compressor determine the capacity and characteristics of the refrigeration system. 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 terminals, plugs, sockets, etc. These connectors are usually made of metal or plastic, with good conductivity and insulation properties, and can ensure the normal operation of the refrigeration system.

[0003] The inventor discovered in his daily work that in the process of using connectors to connect refrigeration compressors and electrical equipment, most of the existing terminal-type connectors on the market have sealing gaskets at the installation position, and bolts are set at the four corners for tightening to achieve sealing of the connection position. Since bolts are installed at each corner, when the staff is performing the tightening operation, they need to tighten each bolt step by step. At the same time, since the tightening operation of each bolt is carried out separately, the force applied to the sealing gasket by the bolt during the tightening process is unbalanced, which can easily lead to one side of the sealing gasket being too tight, thereby interfering with the sealing effect of the sealing gasket. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the tightening operation of each bolt is carried out separately, resulting in uneven force applied to the sealing gasket during the tightening process of the bolt, which easily leads to over-tightening of one side of the sealing gasket, thereby interfering with the sealing effect of the sealing gasket, and to propose a refrigeration compressor connector that is easy to seal.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a refrigeration compressor connector that is easy to seal, comprising a protective sleeve, a wire core and an auxiliary component, the wire core is fixedly connected to the inner wall of the protective sleeve, a plug is fixedly connected to the surface of the wire core, the protective sleeve is fixedly connected to the surface of the plug, a sealing gasket is arranged on the lower surface of the plug, and the auxiliary component is arranged on the upper surface of the plug;

[0006] The auxiliary component includes a linkage unit, which includes a positioning sleeve, the positioning sleeve is fixedly connected to the upper surface of the plug, the upper surface of the positioning sleeve is fixedly connected to a limiting ring, the surface of the limiting ring is rotatably connected to a pulley, the inner wall of the pulley is fixedly connected to a toothed gear, the outer circumference of the positioning sleeve is fixedly connected to a support frame, the inner wall of the pulley is installed with a belt, the belt is meshed with the tooth groove of the toothed gear, and the surface of the support frame is fixedly connected to a protective cover;

[0007] A fastening unit is provided on the surface of the support frame, and the fastening unit includes a threaded pin. A limiting hole is provided on the upper surface of the support frame, and the threaded pin is plugged into the inner wall of the limiting hole. The threaded pin is threadedly connected to the inner wall of the positioning sleeve, and a hexagonal screw head is fixedly connected to the upper surface of the threaded pin. A guide groove is provided on the surface of the threaded pin, and a guide pin is fixedly connected to the inner wall of the pulley.

[0008] Preferably, the positioning sleeve is connected to the slot of the plug, and there are four positioning sleeves, which are diagonally arranged with respect to the plug. The positioning sleeve connected to the slot can constrain the moving direction of the threaded pin during the rotation of the threaded pin to ensure that the threaded pin can be accurately inserted into the slot.

[0009] Preferably, the limiting ring is communicated with the inner wall of the positioning sleeve, and the limiting ring is threadedly connected to the surface of the threaded pin. By fixing the limiting ring above the positioning sleeve, the position of the pulley installed above the positioning sleeve can be limited, and the rotation direction of the pulley can be guided during the rotation of the pulley.

[0010] Preferably, the pulley is connected to the inner wall of the limiting ring, and the pulley abuts against the lower surface of the support frame. Through the cooperation between the pulley and the teeth, the belt can be driven to rotate during the rotation of the pulley, thereby cooperating with the belt to drive the other pulleys to rotate synchronously.

[0011] Preferably, the belt is located on the inner wall of the protective cover, and the protective cover is fixedly connected to the arc surface of the positioning sleeve. The protective cover installed on the outside of the belt can protect the belt, reduce the contact between the belt and external objects, and increase the service life of the belt.

[0012] Preferably, the limiting hole is communicated with the inner wall of the pulley, the threaded pin is plugged into the inner wall of the pulley, the threaded pin passes through the lower surface of the plug, the number of the threaded pins is four, and the four threaded pins are diagonally arranged with respect to the plug. By opening a limiting hole above the support frame, the staff can insert the threaded pin and the installation position of the threaded pin is limited. At the same time, the threaded pin can be preliminarily constrained to ensure the stability of the threaded pin during the tightening process.

[0013] Preferably, the number of the guide pins is three, and the three guide pins are arranged in a circular array about the pulley. The guide pins are slidably connected to the inner wall of the guide groove, and the number of the guide grooves matches the guide pins. By installing the guide pins inside the pulley, the pulley can be driven to rotate during the rotation of the threaded pin, thereby achieving the driving effect of the pulley.

After the installation of the four threaded pins is completed, any one of the hexagonal screw heads is rotated with the help of a tool, the hexagonal screw head cooperates with the threaded pin and the guide pin, and the pulley is rotated. The pulley drives the belt under the cooperation of the meshing teeth, and the belt drives other pulleys. The other pulleys drive the remaining threaded pins to rotate. When the four threaded pins rotate synchronously, the four threaded pins are gradually screwed into the positioning sleeve, and penetrate the plug and screwed into the threaded groove at the installation location. When the four bolt pins are fully tightened, the sealing gasket can be evenly squeezed in cooperation with the plug, so that the sealing gasket is compressed and the plug is sealed. By setting up auxiliary components, the staff only needs to rotate one bolt during the installation operation, thereby reducing the problem of the staff having to rotate multiple bolts and the uneven pressure applied by the bolts, and further improving the convenience and sealing effect of the connector sealing operation.
