Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings.

Referring to fig. 1 to 3, the pin terminal of the present application includes a pin body 10, a torsion spring 20 disposed outside the pin body 10, an insulation cap 30 disposed at a front end of the pin body 10, and a wire connecting member 40 fixed at a rear end of the pin body 10.

The needle body 10 includes a needle insertion end 11, a tail end 12, and a base portion 13 connecting the needle insertion end 11 and the tail end 12. The pin end 11 includes a concave ring 111 and steps 112 at two ends of the concave ring 111. The front end of the needle body 10 is provided with a fixing hole 113. The tail portion 12 includes a main body 121 and a screw 122 extending from the main body 121, and at least one side of the screw 122 is provided with a cut-out portion 123.

The torsion spring 20 includes connecting portions 21 at two ends and a plurality of obliquely arranged elastic strips 22 connected between the two connecting portions 21. The outer diameter of the elastic strip 22 is larger than the outer diameter of the connecting part 21. The torsion spring 20 is sleeved in the concave ring 111, and the connecting portions 21 at two ends are abutted against and fixed on the step portions 112 at two ends of the concave ring 111.

The insulation cap 30 includes a cap top 31 and an insertion portion 32 extending from the cap top 31 and inserted into the fixing hole 113.

The wire connecting member 40 includes a fixing portion 41, a press-connecting portion 42 formed by extending from the fixing portion 41, a sleeve hole 44 opened on the fixing portion 41 to be sleeved in the screw 122, and a press-connecting hole 43 formed on the press-connecting portion 42. The sleeve hole 44 is provided with a mating surface (not numbered) that mates with the notch 123 of the screw 122, preventing the junction element 40 from rotating. The crimping hole 43 presses the outer circumference of the crimping hole 43 after the wire is inserted into the crimping hole 43 to fix the inserted wire. After the screw 122 is sleeved in the sleeve hole 44, a gasket 50 and a fastening pad 60 are further disposed at the rear end of the screw 122, and finally the screw is screwed on the screw 122 through a nut 70 to fix the wiring member 40.
