[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 8In the embodiment of the present invention, an electrical connector that is easy to disassemble and assemble includes an electrical connector housing 1, a sliding connector 2 and a free-end electrical connector 4. The interior of the electrical connector housing 1 is fixedly connected to a square socket 5. Square connecting slide grooves 9 are provided on both sides of the interior of the electrical connector housing 1. A spring positioning column 11 is provided at the tail of the connecting slide groove 9. The interior of the electrical connector housing 1 is slidably connected to the sliding connector 2. A mounting notch is provided on the top of the sliding connector 2. Connecting sliders 18 are provided on both sides of the outside of the top end of the sliding connector 2. The connecting slider 18 is slidably connected to the connecting slide groove 9. A spring positioning hole 19 is provided inside the connecting slider 18. A spring 10 is provided between the spring positioning column 11 and the spring positioning hole 19. The sliding connector 2 is slidably connected to the Anti-slip vertical grooves 17 are provided on both side surfaces of the interior, a free-end electrical connector 4 is provided inside the sliding connector 2, a plug 6 is provided on the top of the free-end electrical connector 4, and positioning cylinders 8 are provided on the upper positions of the two side surfaces of the free-end electrical connector 4. The positioning cylinders 8 and the anti-slip vertical grooves 17 are slidingly connected to prevent the free-end electrical connector 4 from being disconnected from the sliding connector 2 by horizontal external force. Cables 3 are provided at the tails of the socket 5 and the plug 6. The spring 10 between the electrical connector housing 1 and the sliding connector is always in an extended state, which increases the connection strength between the plug 6 and the socket 5. When the electrical connector is forcibly pulled apart by external force, the spring 10 extends again when there is no external force, pushing the plug 6 and the socket 5 to automatically connect, reducing the operation of maintenance personnel.

[0025] Among them, the bottom inner side of the sliding connector 2 is provided with a positive and negative positioning protrusion 14, and the bottom of the free end electrical connector 4 is provided with a positive and negative positioning groove 16. The positive and negative positioning protrusion 14 and the positive and negative positioning groove 16 are slidably connected to prevent the free end electrical connector 4 from being installed in reverse when installing, which may cause damage to the electrical connector;

[0026] Among them, the tail of the sliding connector 2 is provided with a plug-in auxiliary plate 13, which assists in pushing the sliding connector 2 out of the electrical connector housing 1 when disassembling and installing the free-end electrical connector 4, and the operation is convenient. The outer contour of the plug-in auxiliary plate is the same as the outer contour of the electrical connector housing 1;

[0027] Among them, as a further solution of the utility model: a connecting shell 7 is provided on the outside of the plug 6. As a further solution of the utility model: the connecting shell 7 is slidably connected to the outside of the socket 5, thereby increasing the friction between the plug 6 and the socket 5, making it difficult for the plug 6 to slip off and the connecting shell 7 to protect the pins of the plug 6 from damage.

[0028] Among them, a cover plate 12 is provided on the top of the free end electrical connector 4, a connecting slot 15 is provided on the top of the free end electrical connector 4, and a connecting block 21 is provided at the bottom of the cover plate 12. The connecting slot 15 is slidably connected to the connecting block 21, and disassembly is simple and convenient. Positioning blocks 20 are provided on both side surfaces of the cover plate 12, and the positioning block 20 is slidably connected to the anti-slip vertical groove 17 to ensure that the positioning block 20 does not slide horizontally.

[0029] The working principle of the present invention is as follows: before use, the free-end electrical connector 4 needs to be installed in the sliding connector 2, and the plug-in auxiliary plate 13 is pried open with a tool to compress the spring 10, and the plug 6 of the free-end electrical connector 4 is obliquely inserted into the interior of the sliding connector from the mounting notch at the top of the sliding connector, and then the free-end electrical connector 4 is pressed down to make the positioning cylinder 8 and the anti-slip vertical groove 17 slide in connection, so that the positive and negative positioning grooves 16 at the bottom of the free-end electrical connector 4 are slidably connected with the positive and negative positioning protrusions 14, and then the cover plate 12 is covered above the free-end electrical connector 4 so that the connection card slot 15 is slidably connected with the connection card block 21, and the top of the cover plate 12 is pressed down. The positioning block 20 is horizontal to the top of the sliding connector 2, and is slidably connected to the anti-slip vertical groove 17 to ensure that the positioning block 20 does not slide horizontally. Finally, the sliding of the sliding connector 2 is released, and the spring 10 changes from a compressed state to an extended state to push the sliding connector 2 to slide, so that the plug 6 on the free-end sliding connector is inserted into the socket 5 in the electrical connector housing 1; the spring 10 between the electrical connector housing 1 and the sliding connector is always in an extended state, which increases the connection strength between the plug 6 and the socket 5. When the electrical connector is forcibly pulled apart by an external force, the spring 10 will extend again when there is no external force, pushing the plug 6 and the socket 5 to automatically connect.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
