Description
Technical Field
[0001] The utility model relates to the technical field of circuit protectors, and in particular to a circuit protector which is easy to disassemble. Background Art
[0002] A circuit protector, also known as a circuit protection device or circuit protection device, is a device that plays a protective role in a circuit. It is usually used to prevent circuit damage caused by faults such as overcurrent, overvoltage or undervoltage, thereby protecting the safety of the circuit and its related equipment.
[0003] The existing circuit protector includes two circuit protector bodies: a limiting component is provided on the circuit protector body, an insert block is fixedly connected to the right side of the circuit protector body, a locking groove is provided at the bottom of the insert block, and a slot is provided on the left side of the circuit protector body. The utility model realizes the positioning between the circuit protector body and the circuit protector body through the limiting component, and in the process of inserting the insert block into the inner cavity of the slot, the wedge-shaped locking block drives the L-shaped movable block to move downward and squeeze the spring, and finally the rebound force of the spring drives the L-shaped movable block to drive the wedge-shaped locking block into the inner cavity of the locking groove, so as to realize the fixation between the circuit protector body and the circuit protector body. Multiple circuit protector bodies are connected according to this method, and then multiple assembled circuit protectors are picked up and installed on the electric control box bracket, which effectively improves the installation efficiency.
[0004] The applicant believes that the above technology has the following technical problems:
[0005] After the circuit protector is installed on the bracket of the electric control box, the wedge-shaped locking block inside the circuit protector drives the L-shaped movable block to move downward and squeeze the spring. Finally, the resilience of the spring causes the L-shaped movable block to drive the wedge-shaped locking block into the inner cavity of the lock slot, thereby fixing the circuit protector body to the circuit protector body. The limit assembly of the device restricts the circuit protector from moving left and right, and the wedge-shaped locking block inside the circuit protector cooperates with the lock slot to restrict the circuit protector from moving forward and backward. If one of the circuit protectors fails and needs to be replaced, it is necessary to remove the wires on all the circuit protector bodies from the circuit protectors. After the wires are removed, all the circuit protectors can be removed from the bracket of the electric control box for replacement, and the L-shaped movable block drives the wedge-shaped locking block to exit the inner cavity of the lock slot by inserting the block into the slot, and the damaged circuit protector body that needs to be replaced is removed for replacement, which makes the circuit protector disassembly process cumbersome and reduces work efficiency. Utility Model Content

[0009] Furthermore, the limiting component includes a first limiting member and a second limiting member. Both the first limiting member and the second limiting member are fixedly connected to the protector housing. The first limiting member includes a limiting block and a contact block. The cross-sections of both the limiting block and the limiting groove are rectangular structures.

After completion, the connecting piece is released, the connecting piece is reset by the elastic member, and the connecting piece is inserted into the limiting groove to fix the protector shells. After the installation is completed, the protector shell can be installed on the bracket of the electric control box. If one of the circuit protectors fails and needs to be replaced, the wires on the failed circuit protector are first removed. After completion, the connecting piece on the circuit protector is rotated upwards to take the failed circuit protector out of the bracket. After removal, the failed circuit protector can be slid out from the adjacent circuit protector, so that the circuit protector can ensure the installation efficiency while making the disassembly process of the circuit protector simple, thereby improving work efficiency.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.
[0024] As Figure 1 to Figure 6 shown, this embodiment proposes a circuit protector that is easy to disassemble, including a protector housing 1. Inside the protector housing 1, a circuit control module 15 is fixedly connected. A limiting component is provided on one side of the protector housing 1, and a limiting groove 5 corresponding to the limiting component is provided on the other side of the protector housing 1. On the upper side of the protector housing 1 facing the limiting component, there is an installation groove 3. Inside the installation groove 3, there are a connecting shaft 13 and a connecting piece 2. The connecting shaft 13 is fixedly connected to the protector housing 1, and the connecting piece 2 is rotatably connected to the connecting shaft 13. A restoring elastic member 14 is provided on the connecting shaft 13. One end of the restoring elastic member 14 is fixedly connected to the protector housing 1, and the other end of the restoring elastic member 14 is fixedly connected to the connecting piece 2. The restoring elastic member 14 is preferably a torsion spring. The torsion spring has good energy absorption and release capabilities. It can store energy when subjected to an external force and release energy when the external force disappears. Compared with other types of springs, the torsion spring can store a large amount of energy in a relatively small space. This can provide more freedom for designers, making the device or machine more compact and lightweight. On the upper side of the protector housing 1 facing the limiting groove 5, there is a connecting groove 4. The cross-section of the connecting piece 2 and the cross-section of the connecting groove 4 are in a "乛" - shaped structure. This structure increases the contact area between the two parts, improving the connection strength. Above the connecting piece 2, there is a connecting block 16. The connecting block 16 is fixedly connected to the connecting piece 2. The connecting block 16 is provided to more conveniently remove the connecting piece 2 from the connecting groove 4. The cross-section of the connecting block 16 is triangular. The triangular cross-section structure of the connecting block 16 can provide a better rotation balance point, making it more convenient and labor-saving for the connecting piece 2 to rotate upward. The surface of the connecting block 16 is provided with anti-slip lines 17. The anti-slip lines 17 further increase the friction on the surface of the connecting block 16, making it easier for the connecting piece 2 to rotate.
[0025] The limiting assembly in this embodiment includes a first limiting member 6 and a second limiting member 9. The first limiting member 6 and the second limiting member 9 are both fixedly connected to the protector housing 1. The first limiting member 6 includes a limiting block 8 and a contact block 7. The cross-section of the limiting block 8 and the cross-section of the limiting groove 5 are both rectangular structures. The rectangular structure is more stable, so that the limiting block 8 is not easy to deform. One side of the limiting block 8 is fixedly connected to the circuit protector, and the other side of the limiting block 8 is fixedly connected to the contact block 7. The cross-section of the contact block 7 is a trapezoidal structure. The trapezoidal structure can withstand large vertical and horizontal forces and can share part of the pressure and impact load generated during the limiting process. The first limiting member 6 has the same structure as the second limiting member 9. A reinforcement groove 10 is provided below the limiting groove 5. An elastic member 11 and a pressure block 12 are provided inside the reinforcement groove 10. The elastic member 11 preferably adopts a telescopic spring. The telescopic spring has a high elastic coefficient and can generate a large deformation and restoring force under the action of an external force. The telescopic spring is usually made in a spiral form, occupies less space, and is suitable for use in equipment or components with space restrictions. At the same time, they can also automatically adjust their length when the load changes, making the system more compact. One end of the elastic member 11 is fixedly connected to the protector housing 1, and the other end of the elastic member 11 is fixedly connected to the pressing block 12. The cross section of the pressing block 12 is a triangular structure. The triangular structure allows more contact area with the inclined surface of the contact block 7, so that the pressing block 12 can fix the contact block 7.
[0026] Specifically, the implementation process of this embodiment is as follows: if multiple circuit protectors need to be installed on the electric control box bracket, the connecting piece 2 can be rotated upward first, and then the side of the protector housing 1 with the first limiting piece 6 and the second limiting piece 9 is inserted into the side of the other protector housing 1 with the limiting groove 5, and inserted into the limiting groove 5. The pressing block 12 in the limiting groove 5 is squeezed by the first limiting piece 6 or the second limiting piece 9, the elastic piece 11 contracts, and the pressing block 12 moves upward. After the movement, the elastic piece 11 stretches, and the pressing block 12 contacts with the contact block 7 on the limiting piece, so that the circuit protector and The circuit protectors are fixed, the connector 2 is released, the connector 2 is reset by the elastic member 14, and the connector 2 is inserted into the limit groove 5 to fix the protector housing 1. After the installation is completed, the protector housing 1 can be installed on the bracket of the electric control box. If one of the circuit protectors fails and needs to be replaced, the wires on the failed circuit protector are first removed. After completion, the connector 2 on the circuit protector is rotated upward to take the failed circuit protector out of the bracket. After removal, the failed circuit protector can be removed from the adjacent circuit protector.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
