Description

Technical Field

[0001] The utility model relates to a coupler, in particular to a coupler. Background Art

[0002] A coupler is a device that is mainly used to transfer power between systems. In a microwave system, a coupler can divide one microwave power into several paths in proportion, while in a mechanical system, a coupler can connect the shafts of a driving device and a driven device. In addition, a coupler can also be used as an independent hardware interface device, allowing a hardware or electronic interface to be connected to other hardware or electronic interfaces. The upper and lower parts of an existing coupler need to be rotated after being plugged in and docked, and the docking position may lack a transmission structure. During rotation, static friction usually occurs between plastic and metal, which generates a lot of heat and causes certain wear on the connection parts, generating noise during operation, making it inconvenient to improve the silent effect of the equipment. At the same time, it is easy to cause structural damage due to wear, which is not conducive to increasing the service life. Utility Model Content

The inner wall of the spherical groove is rotatably connected to the ball 140, and a ball groove 250 is opened on the outer wall of the top of the lower plastic part 200.

By reducing the friction, the wear on the connection part between the upper plastic part 100 and the lower plastic part 200 is also reduced.

[0028] The specific usage scenario of this embodiment is: by setting the outer wall contacts of the L-pole integrated multi-contact reed 230 and the N-pole integrated multi-contact reed 240 to be several, when using it, the appropriate number of contact structures can be flexibly selected according to the actual usage situation, so as to adjust the current value passing through the L-pole integrated multi-contact reed 230 and the N-pole integrated multi-contact reed 240, which is convenient for use under multiple working conditions.

[0029] The working principle of the utility model is: when used, a person skilled in the art plugs the upper plastic part 100 and the lower plastic part 200 into each other up and down, connects the docking column 110 and the docking ring 210 by screws, and when the upper plastic part 100 and the lower plastic part 200 are rotated in coordination, the ball 140 makes rotational contact with the inner wall of the ball groove 250, so that the upper plastic part 100 and the lower plastic part 200 are in rolling contact, thereby improving the effect of reducing noise and improving wear resistance.
