[0024] Working principle: When in use, the utility model inserts the front end of the free-end electrical connector 2 into the front end inner wall of the fixed electrical connector 1. When the front end of the free-end electrical connector 2 is inserted into the front end inner wall of the fixed electrical connector 1, the docking groove 5 will push the elastic sheet 4 to swing upward. When the elastic sheet 4 swings upward, the elastic potential energy generated by the deformation of the elastic sheet 4 itself will push the upper end of the free-end electrical connector 2 in the opposite direction, so that the front end of the free-end electrical connector 2 remains stable on the front end inner wall of the fixed electrical connector 1. At the same time, when the front end of the free-end electrical connector 2 is inserted into the front end inner wall of the fixed electrical connector 1, the anti-fool boss 6 will Inserted into the inner wall of the anti-foolproof groove 7, the anti-foolproof boss 6 fits with the inner wall of the anti-foolproof groove 7, and the insertion between the free-end electrical connector 2 and the fixed electrical connector 1 can be prevented from being inserted in reverse, so as to avoid the situation where the free-end electrical connector 2 and the fixed electrical connector 1 are inserted into the inner wall of the anti-foolproof groove 7. When the anti-foolproof boss 6 is inserted into the inner wall of the anti-foolproof groove 7, the inclined platform 12 will touch the inner wall of the anti-foolproof groove 7. When the inclined platform 12 touches the inner wall of the anti-foolproof groove 7, under the action of the inclined surface of the inclined platform 12, the limiting slider 11 will move linearly inward along the outer curved surface of the limiting slide bar 10. When the limiting slider 11 moves linearly inward, it will push the compression support Spring 13, when the fool-proof boss 6 continues to be inserted into the inner wall of the fool-proof groove 7, the ramp 12 will move to the opening of the positioning groove 14. When the ramp 12 moves to the opening of the positioning groove 14, the elastic potential energy generated by the compression deformation of the compressed support spring 13 itself will push the limit slider 11 to move linearly outward in the opposite direction. When the limit slider 11 moves linearly outward, it will drive the ramp 12 to be inserted into the inner wall of the positioning groove 14. When the ramp 12 is inserted into the inner wall of the positioning groove 14, the free-end electrical connector 2 can be locked and fixed on the inner wall of the front end of the fixed electrical connector 1. When the free-end electrical connector needs to be contacted When the free-end electrical connector 2 and the fixed electrical connector 1 are locked and fixed, the paddle 19 is pushed inward synchronously. When the paddle 19 is pushed inward synchronously, the limit slider 11 is driven to move linearly inward. When the limit slider 11 moves linearly inward, the inclined platform 12 is driven to leave the inner wall of the positioning groove 14, thereby contacting the locking and fixing between the free-end electrical connector 2 and the fixed electrical connector 1, thereby realizing the anti-foolproof blocking of the insertion between the free-end electrical connector 2 and the fixed electrical connector 1, and facilitating the locking and fixing and contact locking and fixing between the free-end electrical connector 2 and the fixed electrical connector 1;
[0025] At the same time, when the anti-foolproof boss 6 is inserted into the inner wall of the anti-foolproof groove 7, it will drive the contact 15 to be inserted into the inner wall of the mounting circular groove 16. When the contact 15 is inserted into the inner wall of the mounting circular groove 16, the contact 15 will contact the contact switch 17. When the contact 15 contacts the contact switch 17, the contact switch 17 will turn on the prompt light 18. When the prompt light 18 is turned on, it can prompt that the free-end electrical connector 2 is fully inserted into the inner wall of the fixed electrical connector 1, thereby making it easy to observe whether the free-end electrical connector 2 is fully inserted into the inner wall of the fixed electrical connector 1.
