Referring to fig. 7, fig. 7 is a partial enlarged view of a second operating condition of an embodiment of the connector assembly of the present invention. When the first connector 1 and the second connector 2 are disassembled, the shell 11 is pulled along the disassembly direction, the shell 11 and the insulating frame 12 generate relative displacement, and at the moment, the first buckling part 152b and the sixth buckling part 212 still keep the buckling state; during the process of moving the housing 11 along the disassembly direction, the second mating surface 114 on the barb portion 113 on the housing 11 abuts against the first mating surface 159 of the upturned portion 152a, and along with the continued movement of the housing 11, the first elastic arm 152 swings upwards under the abutting and guiding actions between the first mating surface 159 and the second mating surface 114 until the sixth buckling portion 212 is disengaged from the first buckling portion 152b to release the buckling, and the first elastic arm 152 is far away from the mating position, so that the first connector 1 can be pulled out and disassembled. When the frontal tilted portion 152 at the end of the first elastic arm 152 enters the accommodating groove 117 and abuts against the groove surface of the accommodating groove 117, the movement of the housing 11 is restricted.
The first matching surface and the first buckling part are arranged on the first elastic arm, the conversion ratio between the swing quantity generated at the first matching surface and the swing quantity of the first buckling part is higher, the locking and unlocking can be controlled more easily by a user, and the durability is better; when the first connector is unlocked and pulled out, the shell is pulled to enable the shell and the insulating frame to generate relative displacement, so that the first matching surface is abutted with the second matching surface, and the connector is simple and quick to plug.
Referring to fig. 8, fig. 8 is a schematic diagram of a fool-proof mating of an embodiment of a connector assembly. When the first connector 1 is connected with the second connector 2, the 5 connecting portions 131 of the insulating frame 13 are in one-to-one insertion fit with the 5 connecting portions 221 of the insulating frame 22, the connecting portions 131 are protruding cylinders, and the connecting portions 221 are insertion holes. If the connecting portion 131 with the first fool-proof member 133 is abutted with the connecting portion 221 with the second fool-proof member 221b, the first fool-proof member 133 and the second fool-proof member 221b interfere with each other, so that the connecting portion 131 and the connecting portion 221 cannot be inserted. Therefore, when the first fool-proof member 133 is only disposed on the connecting portion 131 and the connecting portion 221, the second fool-proof member 221b is only disposed, or neither the first fool-proof member 133 nor the second fool-proof member 221 is disposed, the insertion between the connecting portion 131 and the connecting portion 221 can be completed. Since the number of the connecting parts 131 and 221 is plural, the first fool-proof member 131 and the second fool-proof member 221 can be assembled in various combinations to realize fool-proof between the connector assemblies.
Referring to fig. 9, fig. 9 is a block diagram of a dust cap in an embodiment of a connector assembly of the present invention. The connector assembly further comprises a dust cover 3 for dust-proof and water-proof shielding of the first connector, the front end of the dust cover 3 is provided with an inlet 30, the dust cover 3 is provided with a plurality of eighth buckling parts 31 on a wall part surrounding the inlet 30, the eighth buckling parts 31 are identical to the sixth buckling parts 212 (shown in fig. 4), and therefore the dust cover 3 can shield the first connector 1 and can lock the first connector.
Referring to fig. 10, fig. 10 is a block diagram of a dust cap in an embodiment of a connector assembly of the present invention. The connector assembly further comprises a dust cover 4 for frequently preventing dust and water for the second connector, wherein the dust cover 4 comprises a cover plate 40, a plug body 41 is arranged on the front side of the cover plate 40, a hanging rope connecting part and a hanging rope 44 are arranged on the rear side of the cover plate 40, and a connecting hole 45 is formed in the tail end of the hanging rope 44; the upper side and the lower side of the cover plate 40 are respectively provided with a turnover part 42 which is bent and extended towards the plug body 41, and the turnover part 42 is provided with a buckling position 43. When the dust cover 4 is mated with the second connector 2, the plug 41 is plugged into the second connector 2, the peripheral wall 211 is located between the plug 41 and the turnover part 42, and the sixth engaging part 212 is engaged with the engaging position 43.
Finally, it should be emphasized that the foregoing description is merely illustrative of the preferred embodiments of the invention, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the invention, and any such modifications, equivalents, improvements, etc. are intended to be included within the scope of the invention.
