[0019] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0020] See appendix Figure 1-4 As shown, an anti-detachment sealed mating connector according to Embodiment 1 includes a socket 1 for mounting on the housing of an electrical device, the socket 1 having a plug 11 for pin insertion; and a power supply connector 2 capable of being plugged into the socket 1 to achieve electrical connection, the power supply connector 2 having a pin connection end 21.
[0021] When the socket 1 is installed on the housing of the equipment requiring power, the connector 21 of the power connector 2 can be inserted into the plug 11, thereby transmitting the current in the power connector 2 to the socket 1, thus supplying power to the equipment requiring power.
[0022] A limiting member 12 is provided on the socket 1 and surrounds the plug 11. The gap between the limiting member 12 and the plug 11 allows the connecting end 21 to be inserted. After the connecting end 21 is inserted into the socket 1, the outer ring surface of the connecting end 21 will contact the inner ring surface of the limiting member 12 to form a sealing structure and protect the plug 11.
[0023] An annular groove 24 is formed on the connecting end 21, and a sealing element is fitted inside the annular groove 24. After the connecting end 21 is inserted into the socket 1, the sealing element will fit tightly against the inner wall of the limit line, further increasing the sealing performance and achieving the effect of dustproof and waterproof, thereby preventing rainwater from affecting the plug 11 and effectively improving the service life of the device when working outdoors.
[0024] A fastening component is provided on the socket 1 to secure it to the housing; the fastening component can secure the socket 1 to the housing of the electrical equipment.
[0025] The connector 21 is provided with an elastic element 22, the power connector 2 is provided with a hoop 23 for constraining the elastic element 22, the elastic element 22 is provided with a locking block, and the seal is provided with a slot 13 that allows the elastic element 22 to be inserted. The slot 13 is provided with a groove 14 that matches the locking block.
[0026] When the connector 21 is inserted into the plug 11, the elastic element 22 will be inserted into the slot 13 to prevent fooling. After the connector 21 is inserted into the plug 11, the locking block on the elastic element 22 will be located in the groove 14 to limit the connection. This prevents the connector 21 from separating from the plug 11 when it is pulled, thus increasing the connection's stability. When the elastic element 22 is pressed, the locking block will disengage from the groove 14. Then, by pulling the connector 21 again, it can be removed, thus separating the connector 21 from the plug 11. The operation is simple and convenient.
[0027] Furthermore, the sealing element includes: a fixing sleeve 3 that can be fitted into the annular groove 24; and a sealing strip 31 that is annularly disposed on the outer surface of the fixing sleeve 3.
[0028] Since the sealing strip 31 is set on the outer ring surface of the fixing sleeve 3, the sealing strip 31 can be installed when the fixing sleeve 3 is fitted into the annular groove 24, and the sealing strip 31 can be disassembled and replaced when it is not fitted into the annular groove 24, which is convenient for maintenance.
[0029] Furthermore, a sealing ring is provided in the gap between the plug 11 and the limiting member 12.
[0030] When the connector 21 is plugged into the plug 11, the connector 21 will abut against the sealing ring, thereby forming a labyrinth seal structure with the sealing element, further improving the sealing strength.
[0031] Furthermore, the fastening assembly includes: a fastening screw 4 that passes through the socket 1; and a nut 41 that is fitted onto the fastening screw 4 and threadedly connected thereto.
[0032] The plug 11 can pass through the reserved hole on the housing of the electrical equipment, and then the fastening screw 4 passes through the socket 1 and the housing. Then the nut 41 is tightened to achieve the fixed installation of the socket 1.
[0033] Furthermore, the back of the insert is provided with a limiting groove 15 that is adapted to the hexagonal screw head of the fastening screw 4.
[0034] The hexagonal head of the fastening screw 4 can be positioned by the limiting groove 15. When the nut 41 rotates, it will not drive the fastening screw 4 to rotate synchronously, thus facilitating the installation of the socket 1.
[0035] Furthermore, the limiting groove 15 is provided with limiting plates 16 on both sides for limiting the hexagonal screw head of the fastening screw 4, and the limiting plate 16 is provided with an anti-loosening block 17 on the side facing the fastening screw 4.
[0036] The limiting plate 16, together with the limiting groove 15, can form a hexagonal positioning groove, thereby placing the hexagonal screw head in the positioning groove, increasing the stability of the hexagonal thread, and the release block can limit the hexagonal screw head to prevent it from falling out of the positioning groove.
[0037] Furthermore, a reinforcing rib 18 is provided on the other side of the limiting plate 16, which can strengthen the connection strength of the limiting plate 16.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
