[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of an electrical automation line protection device, including a protector housing 1. The protector housing 1 serves as the main protective structure of the device, providing an installation base and enclosed protective space for all internal components. It also allows for combination with other components through connection structures on both sides. A snap-fit housing 12 is fixedly connected to the inner wall of one end of the protector housing 1. The snap-fit housing 12 provides a cavity for the installation and movement of the internal spring 15 and push rod 13, serving a protective and limiting function. A spring 15 is fixedly connected to the top of the inner wall of the snap-fit housing 12. The spring 15 provides downward pressure to the push rod 13 through its own elasticity, ensuring the inclined snap-fit 14... It can stably engage and assist in resetting the push rod 13 after it is pushed. The push rod 13 is slidably connected to the inner wall of the buckle housing 12. The push rod 13 can slide up and down inside the buckle housing 12. By moving, it drives the inclined buckle 14 to achieve the engagement or disengagement operation. The inclined buckle 14 is fixedly connected to the bottom outer wall of the push rod 13. The inclined buckle 14 uses the inclined surface to cooperate with the inclined surface of the sleeve 6. Under the action of the spring 15, it is engaged in the corresponding position to fix the protector housing 1 and the connector 2. The inner wall of the protector housing 1 has a slot 16. The slot 16 provides space for the movement of the inclined buckle 14 to ensure that the inclined buckle 14 can smoothly complete the engagement and disengagement actions.
[0033] Reference Figures 4-5The protector housing 1 is snapped with a connector 2. The connector 2 serves as an intermediate connecting component, connecting two sets of protector housings 1 into a whole, and also providing a mounting carrier for components such as the fuse 3. A sleeve 6 is fixedly connected to the outer wall of the connector 2. The sleeve 6 engages with the inclined surface buckle 14 through the inclined surface of its outer wall, which is the key mating structure for realizing the snapping between the protector housing 1 and the connector 2. A sliding ring 7 is slidably connected to the outer wall of the sleeve 6. The sliding ring 7 can slide on the outer wall of the sleeve 6, which can reduce the friction between the inclined surface buckle 14 and the sleeve 6. Simultaneously, the tightness of the locking mechanism is adjusted. Two sets of sleeves 6 and sliding rings 7 are provided, fixed to the outer walls of both sides of the connector 2. The outer wall of the sleeve 6 is beveled, adapting to the bevel of the beveled buckle 14. Two sets of protector housings 1 are provided, which engage with the sleeves 6 on both sides of the connector 2 via the beveled buckle 14. A fixing block 8 is fixedly connected to the inner wall of the connector 2. The fixing block 8 cooperates with the sliding groove 9 of the connecting block 10, providing a track for the installation and sliding of the connecting block 10, ensuring the connection block... The connector 2 is positioned stably. A connecting block 10 is inserted into the outer wall of the fixing block 8. One end of the connecting block 10 is connected to the fixing block 8, and the other end is fixed to the fuse 3, serving to connect and fix the fuse 3. The outer wall of the connecting block 10 is symmetrically provided with sliding grooves 9, which are adapted to the fixing block 8, allowing the connecting block 10 to slide along the fixing block 8, facilitating the installation and removal of the fuse 3. The connecting blocks 10 are symmetrically distributed on the inner wall of the connector 2, and the fuse 3 is fixedly connected to the outer wall of the connecting block 10. The fuse 3 is activated when the circuit experiences overload or short circuit. The circuit automatically melts and cuts off the circuit to protect the safety of the line and equipment. A wiring conduit 11 is fixedly connected to the outer wall of the fuse 3. The wiring conduit 11 is used to connect the external wires to the fuse 3 to realize the electrical connection between the wires and the fuse 3. A wire conduit 4 is fixedly connected to the end of the protector housing 1 away from the inclined buckle 14. The wire conduit 4 is used to guide the external wires into the interior of the protector housing 1 and plays a role in regulating the direction of the wires. There are several groups of wire conduits 4, and the several groups of wire conduits 4 are distributed in a triangle relative to the center of the protector housing 1.
[0034] Reference Figures 3-5A guide rail 17 is fixedly connected to the bottom of the inner wall of the protector housing 1. The guide rail 17 cooperates with the guide groove 19 of the cable bundle 5, providing guidance for the sliding of the cable bundle 5 within the protector housing 1, facilitating the adjustment of the cable bundle 5's position. The cable bundle 5 is inserted into the inner wall of the protector housing 1. The cable bundle 5 organizes and constrains the internal wires through the cable bundle groove 21, preventing the wires from becoming tangled. The notch of the cable bundle 5 is designed in an arc shape, which reduces wear on the wires and facilitates the insertion of the wires into the cable bundle groove 21. The inner wall of the cable bundle 5 is provided with the cable bundle groove 21, which is a space for accommodating wires and used for classifying and organizing them. A rubber clip 20 is fixedly connected to the inner wall of the cable tray 21. The outer wall of the rubber clip 20 is designed to be convex at both ends and concave in the middle. The rubber clip 20 uses its own elasticity and shape to clamp and fix the wires, preventing the wires from loosening. A support block 18 is fixedly connected to the inner wall of the cable tray 21. The support block 18 contacts the wires with its arc-shaped outer wall, providing support for the wires. Together with the rubber clip 20, it enhances the wire fixing effect. The outer wall of the support block 18 is designed to be arc-shaped. A guide groove 19 is opened at the bottom of the cable bundle 5. The guide groove 19 is adapted to the guide rail 17, so that the cable bundle 5 can slide smoothly along the guide rail 17, ensuring that the cable bundle 5 moves smoothly.
[0035] Working principle: In the wire introduction and initial sorting stage, the external wires pass through the wire tube 4 on the inner wall of the other end of the protector housing 1 and enter the device. The guiding and limiting function of the wire tube 4 ensures that the wires enter in an orderly manner, and the triangular distribution of the wire tube 4 keeps the wires spaced, reducing signal or current interference. The wires entering the device are further sorted by the wire bundler 5. The wire bundler 5 can slide along the guide rail 17 on the inner wall of the protector housing 1 and be adjusted to a suitable position according to the number and position of the wires. The wires are classified and placed into the wire bundle slots 21. The support block 18 supports the wires and prevents them from sagging and falling off due to their own weight. The rubber clamp 20 uses elasticity to clamp the wires from both sides to avoid shaking and hard damage. The ring-shaped distribution of the wire bundle slots 21 makes the layout of wires in different directions more orderly.
[0036] Two sets of protector housings 1 are connected via connector 2. During connection, the push rod 13 in the inner wall of the protector housing 12, under the elastic force of the spring 15, pushes the inclined snap 14 to engage with the sleeves 6 on both sides of the connector 2. The inclined design of the sleeve 6 allows the inclined snap 14 to slide in smoothly and complete the engagement. The sliding ring 7 slides along the sleeve 6, buffering the impact force and assisting in positioning during the engagement process, ensuring a stable connection between the two sets of protector housings 1. When disassembly is required, the two protector housings 1 are pressed against the connector 2, and the sliding ring 7 and the inclined snap 14 can complete the disassembly of the protector housing 1 from the connector 2. At the same time, the slot 16 on the inner wall of the protector housing 1 engages with the external mounting structure to fix the entire device in the required position, ensuring stability during operation.
[0037] The fixing block 8 on the inner wall of connector 2 provides sliding support for connector block 10. Connector block 10 can drive the fuses 3 on both sides to adjust their positions, so that fuses 3 can be accurately connected to wires through wiring conduit 11. When the circuit is overloaded or short-circuited, fuse 3 melts in time, cutting off the circuit and preventing the fault from spreading and damaging the entire electrical system. This achieves independent protection of the line and ensures the safe operation of the electrical automation system.
