when the elastic clamping pin is clamped on the hanging part on the elastic release pulling piece before the female plug shell is inserted into the male plug shell, and when the female plug shell is inserted into the male plug shell, the fixed hook is hooked on the hanging part on the elastic release pulling piece, and meanwhile the elastic clamping pin is pushed inwards to be separated from the hanging part.
The anti-misoperation anti-loose automobile connector is characterized in that: elastic hooks are arranged on two sides of the clamping piece, the bottoms of the elastic hooks are connected through spring edges with at least one bending part, and the elastic hooks are matched with first grooves on two sides of the male plug shell.
The anti-misoperation anti-loose automobile connector is characterized in that: the elastic clamping foot is clamped with the hanging part of the elastic release pulling piece through the clamping table at the bottom.
The anti-misoperation anti-loose automobile connector is characterized in that: and positioning protruding points are arranged on two sides of the upper end of the clamping piece and are matched with the second grooves on two sides of the male insertion shell in a positioning manner.
The anti-misoperation anti-loose automobile connector is characterized in that: the male plug shell is provided with a limiting stop bar corresponding to the outer side of the elastic release pull piece.
The anti-misoperation anti-loose automobile connector is characterized in that: the elastic release pulling piece is also provided with a through hole corresponding to the lower end of the hanging part, and the lower end of the hanging part is provided with an inclined plane.
The anti-misoperation anti-loosening automobile connector has the advantages that:
before the female plug shell is plugged with the male plug shell, when the clamping piece is partially inserted into the male plug shell, the elastic clamping foot can enter the through hole formed in the upper end of the hanging portion under the influence of elasticity, so that the bottom of the elastic clamping foot can be clamped on the hanging portion of the elastic release pulling piece, and the clamping piece cannot be continuously inserted at the moment, so that the effect of preventing misoperation is achieved. After the female plug shell is plugged with the male plug shell, the fixed hook in the female plug shell is hung on the hanging part of the elastic release pulling piece, and meanwhile the elastic clamping pin is pushed inwards to be separated from the hanging part, so that the clamping piece can be continuously inserted. When the clamping piece is inserted in place, the limiting part of the top of the clamping piece supports the elastic release pulling piece to limit the elastic release pulling piece, so that the hanging part on the elastic release pulling piece can be tightly hung with the fixed hook on the female plug shell, and looseness is prevented.
The invention is further described below with reference to the drawings.

Detailed Description
Referring to fig. 1 to 8, the anti-misoperation and anti-loosening automobile connector of the present invention comprises: male housing 1, female housing 5 and fastener 6. An elastic release pulling piece 2 is arranged on one side of the male plug shell 1, a hanging portion 3 is arranged in the approximate middle of the elastic release pulling piece 2, and a through hole 4 is formed corresponding to the upper end of the hanging portion 3. The female plug housing 5 is in plug-in fit with the male plug housing 1, and a fixed hook 17 which is connected with the connecting part 3 on the elastic release pull-out piece 2 in a hanging manner is arranged on the inner wall of the female plug housing. The clamping piece 6 is inserted into the inner side of the male plug shell 1 corresponding to the elastic release pulling piece 2, the elastic release pulling piece 2 is limited by the limiting part 7 at the upper end, the side wall of the clamping piece 6 is provided with an elastic clamping foot 8, and the elastic clamping foot 8 is in clamping fit with the hanging part 3 on the elastic release pulling piece 2. The male plug housing 1, the female plug housing 5 and the clamping piece 6 are all plastic pieces and are respectively formed by integral injection molding. After assembly, the male plug shell 1 and the female plug shell 5 are internally connected with a wiring terminal and a wiring harness, and after plugging, the wires can be mutually connected.
Before the female plug housing 5 is plugged into the male plug housing 1, the elastic clamping pin 8 of the clamping piece 6 is clamped on the hanging part 3 of the elastic release pulling piece 2 when the clamping piece 6 is inserted into the male plug housing 1, and the clamping piece cannot be continuously inserted at the moment. After the female plug housing 5 is plugged with the male plug housing 1, the fixing hook 17 is hung on the hanging portion 3 of the elastic release pulling piece 2, and meanwhile, the elastic clamping leg 8 is pushed inwards to be separated from the hanging portion 3, so that the clamping piece can be continuously inserted.
Furthermore, the two sides of the clamping piece 6 are provided with elastic hooks 9, and the bottoms of the elastic hooks 9 are connected through spring edges 12 with a bending part 11, so that the lower end of the clamping piece 6 has certain elasticity, and meanwhile, the firmness of the clamping piece is ensured. The two sides of the male housing 1 are provided with first grooves 10 matched with the elastic hooks 9. During assembly, the lower end of the clamping piece 6 is contracted and arranged in the first groove 10 in a forced extrusion mode, and can move up and down in the first groove 10. Meanwhile, a limiting edge is arranged at the top of the first groove 10, so that the clamping piece can be prevented from falling off.
Further, the elastic clamping leg 8 is clamped with the hanging part 3 of the elastic release pulling piece 2 through a clamping table 18 at the bottom.
Further, positioning protruding points 13 are arranged on two sides of the upper end of the clamping piece 6, and the positioning protruding points 13 are matched with second grooves 14 on two sides of the male housing 1 in a positioning mode. When the clamping piece is inserted into place, the positioning protruding points 13 are positioned in the second grooves 14, so that the clamping piece can be prevented from loosening.
Furthermore, a limiting stop bar 15 is arranged on the outer side of the male plug housing 1 corresponding to the elastic release pull-out piece 2. Can prevent the elastic release pulling piece from being broken when being broken outwards.
Furthermore, the elastic release pulling piece 2 is also provided with a through hole 4 corresponding to the lower end of the hooking portion 3, and the lower end of the hooking portion 3 is provided with an inclined surface 16. The fixed hook in the female plug-in shell can be smoothly clamped into the hanging part along the through hole and the inclined plane, so that the hand feeling of plug-in is improved.
