Under the push of the elastic arm 20, the guide slope 41 slides along the guide section 37 and presses down the conductive arm 11, so that the spiral section 38 is forced to shrink in the arc-shaped opening 40, and a reverse force is applied to the second support section 25 to the contact head 30. The lower end of the guide slope 41 is provided with a chamfered portion 27, and the chamfered portion 27 cooperates with the arc-shaped section 26. An accommodating opening 29 for accommodating the second support section 25 is formed between the contact head 30 and the elastic arm 20. The contact head 30 is also provided with a first protruding portion 42, and the external threaded portion 9 is provided with a second protruding portion 43 and a first concave groove 44 that cooperates with the first protruding portion 42. The upper end of the horizontal section 36 is formed with a second concave groove 45 that accommodates the second protruding portion 43, and the depth of the first concave groove 44 is less than the height of the first protruding portion 42.

[0031] A sliding area 48 is formed in the middle of the external threaded portion 9 , and the first recessed groove 44 and the second protruding portion 43 are located in the sliding area 48 . The contact head 30 is pushed by the elastic arm 20 and slides in the sliding area 48 .

[0032] When the first protrusion 42 is placed in the first concave groove 44 and the second protrusion 43 is placed in the second concave groove 45, the height of the first protrusion 42 is greater than the depth of the first concave groove 44, and under the elastic force of the spiral section 38 and the extension section 47, the conductive arm 11 is kept upward to give an elastic force to the contact head 30, so that the conductive member 5 and the electrical terminal 6 are more stably connected. In addition, the second protrusion 43 can limit the first protrusion 42 through the cooperation between the first protrusion 42 and the second protrusion 43, so as to prevent the first protrusion 42 from being separated from the first concave groove 44.

[0033] A through hole 49 is provided in the middle of the positioning member 3, and a symmetrically arranged guide groove 50 is provided on the inner wall of the through hole 49.

[0034] A downwardly extending lip portion 66 is provided in the middle of the positioning member 3 , and a sliding portion 67 is provided at the lower end of the lip portion 66 . The sliding portion 67 is used to keep the contact head 30 in contact and sliding.

[0035] A matching bevel 57 is provided on the through hole 49 , and the matching bevel 57 can facilitate the installation of the ball stud 53 into the through hole 49 so as to allow the ball stud 53 to enter the guide groove 50 .

[0036] Since there is a height difference between the first limiting section 54 and the second limiting section 55, when the power terminal 6 is rotated, the ball stud 53 will move along the track of the guide groove 50. After moving into the first limiting section 54 and the second limiting section 55, the ball stud 53 will be blocked by the limiting block 56, so that the power terminal 6 will not automatically break away from the first limiting section 54 or the second limiting section 55 when no external force is applied.

[0037] A limiting step 58 is formed between the limiting section 13 and the positioning section 12, and a positioning step 59 is provided at the lower end of the extension arm 33 to match the limiting step 58. A limiting arc surface 60 is formed in the middle of the positioning step 59, and the limiting arc surface 60 matches the outer wall of the limiting section 13.

[0039] When the power is turned off, the power terminal 6 is rotated in the opposite direction, so that the ball stud 53 enters the second limiting section 55 from the first limiting section 54, so that the power terminal 6 moves downward, driving the contact head 30 on the elastic arm 20 to move downward, compressing the conductive arm 11, so that the first protrusion 42 is disengaged from the first recessed groove 44, keeping the first protrusion 42 in contact with the second protrusion 43, and the contact head 30 is disconnected from the conductive member 5.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
