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 apin body 10, atorsion spring 20 disposed outside thepin body 10, aninsulation cap 30 disposed at a front end of thepin body 10, and awire connecting member 40 fixed at a rear end of thepin body 10.

Theneedle body 10 includes aneedle insertion end 11, atail end 12, and abase portion 13 connecting theneedle insertion end 11 and thetail end 12. Thepin end 11 includes aconcave ring 111 and steps 112 at two ends of theconcave ring 111. The front end of theneedle body 10 is provided with afixing hole 113. Thetail portion 12 includes amain body 121 and ascrew 122 extending from themain body 121, and at least one side of thescrew 122 is provided with a cut-outportion 123.

Thetorsion spring 20 includes connectingportions 21 at two ends and a plurality of obliquely arrangedelastic strips 22 connected between the two connectingportions 21. The outer diameter of theelastic strip 22 is larger than the outer diameter of the connectingpart 21. Thetorsion spring 20 is sleeved in theconcave ring 111, and the connectingportions 21 at two ends are abutted against and fixed on thestep portions 112 at two ends of theconcave ring 111.

Theinsulation cap 30 includes acap top 31 and aninsertion portion 32 extending from thecap top 31 and inserted into thefixing hole 113.

Thewire connecting member 40 includes afixing portion 41, a press-connectingportion 42 formed by extending from thefixing portion 41, asleeve hole 44 opened on thefixing portion 41 to be sleeved in thescrew 122, and a press-connectinghole 43 formed on the press-connectingportion 42. Thesleeve hole 44 is provided with a mating surface (not numbered) that mates with thenotch 123 of thescrew 122, preventing thejunction element 40 from rotating. Thecrimping hole 43 presses the outer circumference of thecrimping hole 43 after the wire is inserted into the crimpinghole 43 to fix the inserted wire. After thescrew 122 is sleeved in thesleeve hole 44, agasket 50 and afastening pad 60 are further disposed at the rear end of thescrew 122, and finally the screw is screwed on thescrew 122 through anut 70 to fix thewiring member 40.
