[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0024] like Figure 1-6 As shown, it is a structural schematic diagram of an auxiliary contact housing of an AC contactor that is easy to disassemble and assemble in a preferred embodiment of the utility model;
[0025] In this embodiment, it includes a base 1 and a shell cover 2. Both sides of the shell cover 2 are provided with a plurality of connecting plates 3. The plurality of connecting plates 3 are made of a plastic material with good flexibility and have good deformability. A locking mechanism 4 is provided on the plurality of connecting plates 3. The locking mechanism 4 is integrally connected with the connecting plate 3. The locking mechanism 4 includes a pressing portion 5 and a clamping portion 6. When the pressing portion 5 is pressed, the clamping portion 6 tilts outward. A first clamping portion 7 is integrally provided at the bottom of the clamping portion 6. Both sides of the base 1 are integrally fixed with a plurality of second clamping portions 8. Both sides of the bottom of the plurality of second clamping portions 8 are integrally provided with connecting blocks 9. The connecting blocks 9 are symmetrical structures. Locking buckles 10 are rotatably installed on the connecting blocks 9. The outer surface of the connecting block 9 is provided with a plurality of anti-skid grooves 11 in an annular array. The inner surface of the locking buckle 10 is provided with a plurality of anti-skid strips 12 in an annular array. The anti-skid strips 12 are used in conjunction with the anti-skid grooves 11 so that the locking buckle 10 has an anti-skid effect when it rotates.
[0026] In this embodiment, the first buckle 7 is engaged with the second buckle 8, and both the first buckle 7 and the second buckle 8 are provided with chamfers. When the first buckle 7 is connected with the second buckle 8, the first buckle 7 is offset away from the second buckle 8 through the action of the chamfered inclined surface. When the base 1 and the shell cover 2 are fully fitted, the first buckle 7 rebounds and engages with the second buckle 8.
[0027] In this embodiment, a groove 13 is provided on the inner side of the top opening of the base 1, and the groove 13 is arranged along the inner side of the opening of the base 1. A boss 14 is provided on the inner side of the bottom opening of the shell cover 2, and the boss 14 is arranged along the inner side of the opening of the shell cover 2. The boss 14 is snapped into the groove 13, which can effectively strengthen the sealing closure between the base 1 and the shell cover 2.
[0028] In this embodiment, the lock buckle 10 can rotate about the connecting block 9. The lock buckle 10 is arranged in a "U"-shaped structure. The lock buckle 10 is looped on the outside of the clamping part 6. The clamping part 6 and the first clamp 7 are limited by the lock buckle 10 to avoid loosening and falling off between the first clamp 7 and the second clamp 8. When disassembly is required, the lock buckle 10 is rotated downward to disengage the limiting effect on the clamping part 6 and the second clamp 8, and the pressing part 5 can be pressed to make the clamping part 6 tilt up, and the first clamp 7 and the second clamp 8 are disengaged, and the base 1 and the shell cover 2 can be disassembled.
[0029] In this embodiment, an anti-skid rubber block 15 is provided on the top surface of the pressing part 5 to prevent the staff from slipping when pressing the pressing part 5. The anti-skid rubber block 15 is made of a relatively soft rubber material, which can protect the staff's hands.
