For example, detachable connection can be selected according to the needs of screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods. The various technical features in the creation of the utility model can be combined interactively without conflicting with each other.

[0025] Please refer to Figure 1-Figure 4 The utility model provides an electrical connector, comprising a base 2, a latch 1 and an injection molding part 91, wherein the injection molding part 91 is arranged on the base 2, the latch 1 is arranged at both ends of the base 2, a protruding platform 3 is respectively arranged on the front side and the rear side of the base 2, and at least one groove 4 is respectively arranged on the protruding platform 3, and a rotating column 5 is arranged in each of the grooves 4; the latch 1 comprises two side plates 12 and a handle 11 for connecting the two side plates 12, and the two side plates 12 are respectively embedded in the grooves 4 on the front side and the rear side of the base 2, and are pivotally connected to the rotating column 5. Among them, at least a part of the surface of the two side plates 12 of the latch 1 is close to the side wall of the groove 4 at the same time, so that the latch 1 can be deformed and contact with the protruding platform 3 when it is impacted in the locked state, transition state and release state.

[0026] Furthermore, the base 2 is provided with an opening, the opening is rectangular, a terminal block 7 and a plurality of terminals are embedded in the opening, and the terminals penetrate the terminal block 7. The terminal block 7 is provided with a grounding column 8, and the grounding column 8 is used to connect the base 2 of the electrical connector to the ground to form a good grounding loop, so that the electrical connector is in a relatively stable potential state. When the equipment has a fault such as leakage, the leakage current will be discharged to the ground through the grounding column 8 to avoid electric shock accidents caused by the current passing through the human body or other equipment. The grounding column 8 can also effectively eliminate the electrostatic charge between the electrical connector and the ground to prevent electrostatic interference.

[0027] The two ends of the terminal block 7 are provided with buckle teeth 71 , and the buckle teeth 71 are elastic. The inner wall of the base 2 is provided with buckle grooves 21 , and the buckle teeth 71 are buckled and connected with the buckle grooves 21 to achieve a fixed connection between the base 2 and the terminal block 7 .

[0028] Furthermore, the front and rear surfaces of the protruding platform 3 are T-shaped, and two grooves 4 are provided on the protruding platform 3, and the two grooves 4 are respectively located on both sides of the protruding platform 3, and the side walls of the groove 4 are sequentially provided with a first boss surface 41, a second boss surface 42 and a third boss surface 43 connected to each other, the first boss surface 41 and the third boss surface 43 are perpendicular to each other, and the second boss surface 42 is a curved surface, and the two side plates 12 of the latch 1 are respectively provided with a first abutting surface 121, a second abutting surface 122 and a third abutting surface 123 connected to each other, the first abutting surface 121 and the third abutting surface 123 are perpendicular to each other, and the second abutting surface 122 is a curved surface.

[0029] Furthermore, an arc structure 6 is provided on the groove 4, and an arc slot is formed between the arc structure 6 and the rotating column 5. A protrusion 14 is provided on the latch 1. When the latch 1 is pivotally connected to the rotating column 5, the protrusion 14 is slidably provided on the arc slot.

[0030] Specifically, the arc structure 6 is concentrically arranged along the outer circumference of the rotating column 5, and the arc structure 6 is arranged between the rotating column 5 and the side wall of the groove 4, and is used to further fix the connection between the rotating column 5 and the latch 1, and prevent the rotating column 5 from slipping from the connecting groove 13 of the latch 1 during the rotation process. In addition, the arrangement of the arc structure 6 can also reduce the wear between the side plate 12 and the groove 4, thereby extending the service life of the electrical connector.

[0031] Furthermore, the handle 11 of the latch 1 may be provided with an anti-slip strip to increase friction and prevent hand slipping. The anti-slip strip can increase friction to prevent hand slipping caused by lubricating substances such as sweat or grease, thereby improving safety when holding objects. In addition, the anti-slip strip can also protect the handle 11 and prevent the handle 11 from being damaged due to wear.

[0032] Furthermore, a connecting groove 13 is provided on the inner wall of the side plate 12 , and the connecting groove 13 is pivotally connected to the rotating column 5 , so that the latch 1 can rotate on the protruding platform 3 .

[0033] Specifically, the connection groove 13 has a notch, and the notch facilitates the rotation column 5 to slide into the connection groove 13. The depth of the connection groove 13 is deeper than the depth of the notch, which can clamp the rotation column 5 and prevent the rotation column 5 from sliding out of the connection groove 13. The connection groove 13 has a protrusion 14 arranged on the outer periphery of the connection groove 13. When the latch 1 is pivotally connected to the rotation column 5, the protrusion 14 is embedded between the arc structure 6 and the rotation column 5, providing support force for the latch 1 when rotating, thereby improving the structural stability.

[0034] In this embodiment, the electrical connector has three states. When the electrical connector is in a locked state, the first boss surface 41 is in contact with the first abutting surface 121, the rotating column 5 is fixed in the connecting groove 13, and the protrusion 14 on the connecting groove 13 and the arc structure 6 together form a circular fixing cavity for preventing the rotating column 5 from slipping; when the electrical connector is in a released state, the third boss surface 43 is in contact with the third abutting surface 123; when the electrical connector is in a transition state, neither the first boss surface 41 nor the third boss surface 43 is in contact with the first abutting surface and the third abutting surface.

[0035] In fact, no matter in the locked state, the transition state or the released state, there is a gap between the curved surface of the second abutting surface 122 of the side plate 12 and the vertical first boss surface 41, the curved surface of the second boss surface 42 and the horizontal third boss surface 43, and the minimum distance between the two or the maximum width of the gap is greater than zero but less than 500 microns, and the optimal distance is less than 150 microns. The aforementioned distance ensures that the side plate 12 can rotate normally when in use, but when impacted, the side plate 12 and the rotating column 5 will be subjected to force and elastically deformed, and the side plate 12 will contact any surface of the protruding platform 3 to transmit the force to the protruding platform 3 to prevent the rotating column 5 from breaking.

[0036] Furthermore, a cable 92 is disposed in the injection molding part 91 , and the cable 92 is electrically connected to the terminal. The injection molding part 91 wraps the cable 92 to fix and protect the cable 92 .

[0037] The utility model adds a transverse boss surface so that the latch 1 can transmit the impact force to the base 2 when it is impacted in any situation, thereby preventing the rotating column 5 from breaking, thereby ensuring the stability and safety of the connector.

[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
