It includes a fixed bracket and a plurality of connector monomers arranged on the fixed bracket, the longitudinal dimensions of the plurality of connector monomers are consistent, and they are laterally connected in sequence to form a first connector row, and each connector monomer has a first side wall and a second side wall that are laterally opposite; wherein a first slot is provided on the first side wall, and a first plug-in block is provided on the second side wall, and the first plug-in blocks and the first slots on two adjacent connector monomers are correspondingly plugged in. The number of connector monomers can be flexibly increased or decreased according to the number of wiring harnesses of a specific vehicle model, thereby improving compatibility, and the structure is simple, and the connector monomers can be easily and quickly disassembled and replaced, which can avoid the cost waste caused by repeated development of connector monomers of different structures or sizes;

[0004] However, the filtering device in the prior art still has the following defects:

[0005] However, the existing connector relies on the crown spring inside the plug to achieve locking when connecting the plug and the socket. After the socket and the plug are plugged in and out many times, the elasticity of the crown spring decreases, resulting in a decrease in the locking force, thereby affecting the connection between the socket and the plug. Therefore, it is very necessary to design a modular connector that does not affect the locking force after multiple plugging and unplugging. Utility Model Content

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1:

[0026] A modular connector with a locking mechanism, comprising a male plug 1, one end of which is plugged with a female plug 2, and the inner diameter of the female plug 2 is adapted to the male plug 1, a connecting sleeve 3 is installed on the outer side of the male plug 1, and grooves 4 are symmetrically provided on the surface of the female plug 2, and a locking assembly is provided in the groove 4 provided on the female plug 2. By installing the connecting sleeve 3 on the outer side of the male plug 1, the female plug 2 can be conveniently inserted between the male plug 1 and the connecting sleeve 3;

[0027] The locking assembly includes a retaining spring 5, a rotating block 6, a guide rod 7, a guide groove 8 and a retaining groove 9. The groove 4 provided on the surface of the busbar plug 2 is hinged with a rotating block 6 through a hinge. The inner core of the hinge is installed with a retaining spring 5. The rotating block 6 rotates in the groove 4 provided in the busbar plug 2 through the hinge and the retaining spring 5. The surface of the rotating block 6 is symmetrically installed with a guide rod 7. The inner wall of the groove 4 is symmetrically provided with a guide groove 8. The rotating block 6 rotates in the busbar plug 2 through the guide rod 7 and the guide groove 8. The surface of the connecting sleeve 3 is symmetrically provided with retaining grooves 9 adapted to the rotating block 6. The rotating block 6 penetrates the retaining groove 9 and extends to the outside of the connecting sleeve 3. The rotating block 6 is squeezed by the connecting sleeve 3. After the busbar plug 2 is inserted into the male plug 1, the rotating block 6 is abutted against the retaining groove 9 under the action of the retaining spring 5, thereby realizing the quick connection and locking of the busbar plug 2 and the male plug 1.

[0028] The connecting sleeve 3 is adapted to the busbar plug 2, and the busbar plug 2 is inserted between the male plug 1 and the connecting sleeve 3, so as to improve the fit between the busbar plug 2 and the male plug 1;

[0029] The surface of the male plug 1 is sleeved with an extrusion ring 10, which slides between the male plug 1 and the connecting sleeve 3. Two groups of springs 12 are symmetrically installed on one side of the extrusion ring 10. One end of the four springs 12 away from the extrusion ring 10 is connected to the connecting sleeve 3. The extrusion ring 10 is squeezed by the spring 12. When the bus plug 2 is inserted into the male plug 1, the bus plug 2 squeezes the extrusion ring 10 and is subjected to pressure. The extrusion ring 10 contracts the extrusion spring 12 inwards and cooperates with the rotating block 6 to start a good locking effect between the bus plug 2 and the male plug 1.

[0030] The surface of the extrusion ring 10 is symmetrically provided with a stabilizing block 11, and the inner wall of the connection sleeve 3 is symmetrically provided with a blind groove adapted to the stabilizing block 11. The extrusion ring 10 slides between the connection sleeve 3 and the male line plug 1 through the blind groove and the stabilizing block 11, so that the position of the extrusion ring 10 can be limited and the stabilizing effect of the extrusion ring 10 can be improved;

[0031] Embodiment 2:

[0032] Although the above technical solution improves the locking effect between the bus plug 2 and the male plug 1 through the locking component, in order to further improve the locking effect between the connectors, the surface of the male plug 1 is provided with an extrusion ring 10, and the extrusion ring 10 slides between the male plug 1 and the connecting sleeve 3. Two groups of springs 12 are symmetrically installed on the surface of one side of the extrusion ring 10. The ends of the four springs 12 away from the extrusion ring 10 are connected to the connecting sleeve 3. The extrusion ring 10 is squeezed by the spring 12. When the bus plug 2 is inserted into the male plug 1, the bus plug 2 squeezes the extrusion ring 10 and is subjected to pressure, and the extrusion ring 10 contracts and squeezes inward. The spring 12, in conjunction with the rotating block 6, can achieve a good locking effect between the busbar plug 2 and the male plug 1, so in this embodiment, an extrusion ring 10 is arranged between the male plug 1 and the connecting sleeve 3. When the busbar plug 2 is squeezed by the extrusion ring 10 and subjected to pressure, the extrusion ring 10 contracts the extrusion spring 12 inward, and the rotating block 6 is abutted against the card slot 9 under the action of the retaining spring 5. Under the tension of the spring 12, the extrusion ring 10 always squeezes the busbar plug 2, providing a reverse force to the busbar plug 2, so that the rotating block 6 is always abutted against the card slot 9, so that the busbar plug 2 and the male plug 1 are further lifted;

[0033] Working principle: By installing a connecting sleeve 3 on the outside of the male plug 1, the bus plug 2 can be easily inserted between the male plug 1 and the connecting sleeve 3. The connecting sleeve 3 squeezes the rotating block 6. After the bus plug 2 is inserted into the male plug 1, the rotating block 6 is abutted against the card slot 9 under the action of the retaining spring 5, thereby realizing the quick connection and locking of the bus plug 2 and the male plug 1. When the bus plug 2 is inserted into the male plug 1, the bus plug 2 squeezes the extrusion ring 10 under pressure, and the extrusion ring 10 contracts the extrusion spring 12 inward, and cooperates with the rotating block 6, which can start a good locking effect between the bus plug 2 and the male plug 1, and the locking effect is further improved, making the connection between the two more firm.
