[0030] Example 1

[0031] like Figures 1 to 3 As shown, this embodiment provides a rectangular connector quick plug-in and self-locking structure, including a positioning column accessory connected to the rectangular connector plug 1 and a self-locking accessory connected to the rectangular connector socket 8; the positioning column accessory includes a positioning column pin 3, a positioning intermediate block 4 is movably sleeved on the positioning column pin 3, one end of the positioning column pin 3 is connected to the fixing nut 2, and the other end is connected to the positioning column head 5; the self-locking accessory includes a self-locking head column 6 installed on the rectangular connector socket 8, the self-locking head column 6 is provided with a channel opposite to the positioning column pin 3, and the self-locking head columns 6 on both sides of the channel are provided with mutually symmetrical limiting structures.

[0032] Specifically, the limiting structure includes a mounting hole provided on the self-locking head column 6 , a limiting column 11 is installed in the mounting hole, a spring 10 is sleeved on the limiting column 11 ; and a limiting block 9 is connected to the limiting column 11 .

[0033] The outer diameter of the limiting block 9 is larger than the outer diameter of the limiting column 11 , the mounting hole is a step-type structure, and the limiting block 9 is located in the mounting hole at the end with the larger inner diameter.

[0034] The two limit blocks 9 are both provided with inclined surfaces, and the inclined surfaces on the two limit blocks 9 are installed opposite to each other to form a through groove for the positioning column head 5 to pass through.

[0035] During the actual installation and use process, the spring 10 and the limit block 9 are installed into the hole in the self-locking column 6, and then the limit column 11 is installed into the hole in the self-locking column 6 from the outside of the self-locking column 6 and locked on the limit block 9. Finally, the self-locking accessory is installed into the accessory hole of the rectangular connector socket 8 and locked with the locking nut 7 to lock the self-locking accessory on the rectangular connector socket 8.

[0036] Specifically, the positioning column head 5 is a frustum structure. The positioning column middle block is also a frustum structure and is symmetrical with the positioning column head 5, and a locking structure is provided between the positioning middle block 4 and the positioning column head 5.

[0037] The locking structure includes a small frustum connected to the positioning middle block 4, and a groove for locking the small frustum is provided on the positioning column head 5.

[0038] During actual installation and use, the middle block of the positioning column is installed into the positioning pin, and then the positioning column head 5 is fixed on the positioning column pin 3. The middle block of the positioning column can slide on the positioning column pin 3, and the positioning column accessory is installed into the accessory hole of the rectangular connector plug 1. The fixing nut 2 is fixed on the positioning column pin 3. The positioning column accessory as a whole can move back and forth on the rectangular connector plug 1.

[0039] Specifically, in order to make the positioning column head 5 more stably detached during separation, the present application also connects mutually attractive magnets in the small cone and the groove body, so that the positioning intermediate block 4 can be more tightly and firmly in contact with the positioning column head 5, preventing the positioning column head 5 from falling off during the pushing process.

[0040] Specifically, the self-locking column 6 is a T-shaped structure, a through hole for installing the self-locking column 6 is provided on the rectangular connector socket 8, a thread is provided on the connecting portion of the self-locking column 6, and the connecting portion of the self-locking column 6 is passed through the through hole and fixed using a locking nut 7.

[0041] When the rectangular connector plug 1 and the rectangular connector socket 8 of this embodiment are plugged in, the two plugging surfaces are directly aligned and then force is applied, the positioning column head 5 moves to the right, and the limit block 9 moves outward after being squeezed by the positioning column head 5. After the positioning column head 5 is in place, the limit block 9 moves inward after being pressed by the spring 10, and the positioning column head 5 is clamped. Therefore, after being plugged in place, the connector itself cannot fall out after being subjected to an external force within a limited range, thereby achieving a self-locking effect.

[0042] When the rectangular connector plug 1 and the rectangular connector socket 8 need to be separated, it is necessary to first push the fixing nut 2 ends of the positioning pin 3 on the accessory of the rectangular connector plug 1 forward, and the middle block of the positioning column moves forward after being subjected to force, and the limit block 9 moves outward into place after being squeezed by the positioning column head 5, and the middle block of the positioning column and the positioning column head 5 partially overlap to form a whole, and then pull the fixing nut 2 ends of the positioning pin 3 on the accessory of the rectangular connector plug 1 backward, so that the positioning column head 5 can be removed from the limit block 9, so that the rectangular connector plug 1 and the rectangular connector socket 8 are separated.

[0043] The rectangular connector quick-release self-locking structure in this embodiment only needs to align the connectors and insert them into place when the rectangular connector plug 1 and the rectangular connector socket 8 are plugged in, so that the quick plug-in and self-locking function can be achieved, which is convenient and fast. In addition, when the rectangular connector plug 1 and the rectangular connector socket 8 are separated, the positioning column pin 3 at the end of the rectangular connector plug 1 is gently pushed forward and then pulled out backward to complete the quick separation, which is simple in structure and safe and reliable.

[0044] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
