[0032] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0033] Please also read Figures 1 to 4 The embodiment of the present application provides a wiring terminal, which includes a male end 10 and a female end 20. The male end 10 is provided with an extension portion 11, and a first accommodating cavity 101 is formed inside the extension portion 11. The end of the extension portion 11 is connected to a first insulating member 12. The female end 20 is provided with an enclosure portion 21, and a second accommodating cavity 201 is formed inside the enclosure portion 21 and a second insulating member 22 is installed. The outer peripheral wall of the enclosure portion 21 is provided with a plurality of deformation seams 202 at intervals and is detachably connected to a clamping ring 30. The male end 10 is plugged into the female end 20 so that the extension portion 11 is inserted into the second accommodating cavity 201 and the second insulating member 22 is inserted into the first accommodating cavity 101.

[0034] By arranging the male end 10 and the female end 20 to cooperate with each other, the enclosure 21 of the female end 20 forms a second accommodating cavity 201 for the extension portion 11 of the male end 10 to be inserted, and the outer peripheral wall of the enclosure 21 is spaced apart with a plurality of deformation seams 202, which can increase the elastic deformation range of the enclosure 21 to reduce the fatigue deformation of the enclosure 21 after multiple insertions and withdrawals of the extension portion 11. The retaining ring 30 is used to limit the deformation amount of the inner diameter of the outer peripheral wall of the enclosure 21, so that the extension portion 11 and the enclosure 21 can be pressed against each other, thereby ensuring that the terminal block is more durable and has a longer service life.

[0035] When the male end 10 and the female end 20 are respectively installed in the housing of the electrical connector, the male end 10 is provided with a first insulating member 12 to prevent the user's fingers from directly touching the end of the extension portion 11, and the female end 20 is provided with a second insulating member 22 to prevent the user's fingers from directly touching the inner wall of the enclosure portion 21, thereby reducing the risk of electric shock to the user and making the use of the terminal block safer.

[0036] In application, the male end 10 can be made of any material among copper, aluminum, and copper alloy, and the female end 20 and the male end 10 are made of the same material, so that both the male end 10 and the female end 20 can undergo elastic deformation.

[0037] Specifically, when the enclosure 21 does not produce elastic deformation, the outer diameter of the extension portion 11 of the enclosure 21 is larger than the inner diameter of the enclosure 21, so that the extension portion 11 can be pressed against the enclosure 21; when the enclosure 21 is in a state of maximum elastic deformation, the outer diameter of the extension portion 11 is smaller than the inner diameter of the enclosure 21, so that the extension portion 11 can be repeatedly plugged in and out of the enclosure 21.

[0038] In application, the first insulating member 12 can be made of plastic or rubber, and the second insulating member 22 and the first insulating member are made of the same material.

[0042] In application, the annular groove 203 surrounds the outer wall of the enclosure 21 in the circumferential direction, and the annular groove 203 limits the radial displacement of the retaining ring 30 along the enclosure 21, thereby preventing the retaining ring 30 from detaching from the enclosure 21 and ensuring the effective connection between the male end 10 and the female end 20.
