Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, and in particular to a waterproof connector assembly for microgrid cables that is easy to fix. Background Technology

[0002] Waterproof cable joint assemblies are core components that ensure the stability and safety of power transmission. Cable joints can be used to connect, insulate and protect cables, and are widely used in industrial fields. They can extend, branch, repair and connect cables, ensuring the normal transmission and use of wires.

[0003] However, existing waterproof cable connector assemblies for microgrids have shortcomings in clamping and fixing cables of different diameters. The current mainstream cable connectors have poor cable diameter compatibility, requiring, for example, the replacement of clamping sleeves with different inner diameters to adapt to the cable diameter. This method has obvious limitations. On the one hand, it increases the construction preparation time. On the other hand, the fit between the clamping sleeve and the cable depends on manual selection. If there is a slight deviation in the diameter matching, it is easy to have problems of being "too loose" or "too tight". Therefore, a waterproof cable connector assembly for microgrids that is easy to fix is ​​proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waterproof connector assembly for microgrid cables that is easy to fix, aiming to improve the problem of poor compatibility of some cable connectors with cable diameter in the prior art.

[0006] As a further description of the above technical solution: the fixing component includes a fixing pin, which is slidably connected to the connecting sleeve, and a disc is fixedly connected to the outer wall of the fixing pin. The upper surface of the disc is elastically connected to the connecting sleeve through a compression spring, and a locking block is fixedly connected to the inner wall of the connecting sleeve.

[0007] As a further description of the above technical solution: the clamping piece is hinged to the left end of the positioning bolt, and the pin is inserted into the outer wall of the rotating ring.

[0008] As a further description of the above technical solution: the arc-shaped grooves are configured in multiple groups and distributed in a ring array.

[0009] As a further description of the above technical solution: the outer wall of the pin is fixedly connected to one end of the return spring, and the other end of the return spring is fixedly connected to the inner wall of the ring.

[0010] As a further description of the above technical solution: the inner wall of the connecting sleeve is in contact with the outer wall of the sealing ring.

[0011] As a further description of the above technical solution: the upper surface of the disk is fixedly connected to one end of the compression spring, and the other end of the compression spring is fixedly connected to the inner wall of the connecting sleeve.

[0012] As a further description of the above technical solution: the fixing pin is inserted into the slot, and the locking block is engaged with the inner wall of the sleeve.

[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of a waterproof microgrid cable connector assembly that is easy to fix. It includes a sleeve 1, which is mainly used to cooperate with a connecting sleeve 3 to achieve an overall connection of the cable connector. The inner wall of the sleeve 1 has a groove for sliding a locking block 7. The inner wall of the sleeve 1 also has a slot 2, which can precisely engage with a fixing pin 4 on the connecting sleeve 3. A sealing ring 8 is fixedly connected to the outer wall of the sleeve 1. The inner wall of the connecting sleeve 3 contacts the outer wall of the sealing ring 8. The sealing ring 8 is made of rubber, and its elastic deformation fills the gap between the sleeve 1 and the connecting sleeve 3, effectively preventing external liquid from entering the connector. The connecting sleeve 3 is detachably installed on the right end of the sleeve 1. The connecting sleeve 3 is a connecting component that connects other components. An end cap 9 is threadedly connected to the right end of the connecting sleeve 3. The end cap 9 provides protection for the inside of the connecting sleeve 3 and can be unscrewed during cable installation to adjust the clamps, then tightened after installation, further improving the overall connection. To ensure the sealing of the components, a ring 10 is fixedly connected to the inner wall of the right end of the connecting sleeve 3. The ring 10 provides a stable support structure for the rotation of the rotating ring 11. An arc-shaped groove 17 is formed on the inner wall of the ring 10, and the rotating ring 11 is rotatably connected to the inner wall of the ring 10. The inner wall of the rotating ring 11 has mounting holes for fixing the positioning bolt 13 and multiple slots that are adapted to the pin 15. By rotating the rotating ring 11, the clamping piece 14 can be adjusted to contract or expand. The positioning bolt 1 is slidably connected through the inner wall of the arc-shaped groove 17. 12. The inner wall of the rotating ring 11 is connected to a positioning bolt 2 13. When the rotating ring 11 rotates, the clamping piece 14 moves under the drive of the positioning bolt 2 13. The positioning bolt 12 slides along the arc groove 17. The outer wall of the positioning bolt 2 13 is hinged with a clamping piece 14. The clamping piece 14 is hinged to the left end of the positioning bolt 12. The clamping piece 14 is arc-shaped. Multiple sets of clamping pieces 14 can be adapted to cables of different diameters by synchronously contracting or opening. The inner wall of the ring 10 is provided with a limit mechanism. The limiting mechanism includes a pin 15, which is inserted into a slot in the inner wall of the rotating ring 11 to lock the position of the rotating ring 11 and ensure that the clamping plate 14 holds the cable stably. The pin 15 passes through and slides on the inner wall of the ring 10, and the outer wall of the pin 15 is elastically connected to the ring 10 through a return spring 16.

[0019] Reference Figure 2 , Figure 6 and Figure 7The fixing component includes a fixing pin 4, which is inserted into the slot 2. Under the action of the compression spring 5, the fixing pin 4 is inserted into the slot 2 of the sleeve 1, fixing the relative position of the two and preventing the connection from loosening. The fixing pin 4 passes through and slides on the connecting sleeve 3. A disc 6 is fixedly connected to the outer wall of the fixing pin 4. The disc 6 provides an installation point for the compression spring 5. The upper surface of the disc 6 is elastically connected to the connecting sleeve 3 through the compression spring 5. The upper surface of the disc 6 is fixedly connected to one end of the compression spring 5, and the other end of the compression spring 5 is fixedly connected to the inner wall of the connecting sleeve 3. When the fixing pin 4 is pulled upward, the compression spring 5 is compressed, causing the fixing pin 4 to retract into the connecting sleeve 3. When resetting, the elasticity of the compression spring 5 is used to move the fixing pin 4 downward. A locking block 7 is fixedly connected to the inner wall of the connecting sleeve 3. The locking block 7 is locked onto the inner wall of the sleeve 1. The locking block 7 can move in the groove of the sleeve 1 to achieve the initial fixing of the two.

[0020] Reference Figures 3-5 The pin 15 is inserted into the outer wall of the rotating ring 11. The arc-shaped groove 17 is set in multiple groups and distributed in a ring array to ensure that the clamping piece 14 can only open or contract along the trajectory defined by the arc-shaped groove 17, thereby achieving convergence towards the center or opening outward. The outer wall of the pin 15 is fixedly connected to one end of the return spring 16, and the other end of the return spring 16 is fixedly connected to the inner wall of the ring 10. When the pin 15 is pushed, the return spring 16 will be compressed to make the pin 15 disengage from the groove of the rotating ring 11. When resetting, the elasticity of the return spring 16 is used to carry the pin 15 back into the groove of the rotating ring 11.

[0021] Working principle: When adjusting the size of the clamp for the cable connector, first unscrew the end cap 9 to see the ring 10 fixed to the right end of the connecting sleeve 3. Then push the pin 15 outward. The pin 15 compresses the return spring 16 and disengages from the slot of the rotating ring 11. Next, manually rotate the rotating ring 11 clockwise. Since the length of the clamping piece 14 is fixed, the positioning bolt 12 will slide upward along the arc groove 17 as the rotating ring 11 rotates. At this time, the clamping piece 14 will converge towards the center with the positioning bolt 13 as the fulcrum. At the same time, multiple sets of clamping pieces 14 will shrink synchronously in the circumferential direction. When the clamping piece 14 is tightly attached to the outer wall of the cable, stop rotating the rotating ring 11 and no longer push the pin 15. The pin 15 re-inserts into the slot of the inner wall of the rotating ring 11, completing the locking of the clamping piece 14. If you want to increase the size of the clamp, simply rotate the rotating ring 11 in the opposite direction.

[0022] When connecting one end of the cable to the sleeve 1 after passing through the end cap 9 and the connecting sleeve 3, first pull the fixing pin 4 upwards to compress the spring 5 into the inner wall of the connecting sleeve 3. Then, simply align the locking block 7 on the inner wall of the connecting sleeve 3 with the groove entrance of the sleeve 1 and insert it. Then rotate the connecting sleeve 3 half a turn to engage the locking block 7 with the groove on the inner wall of the sleeve 1, completing the initial positioning of the two. At this time, the right end of the sleeve 1 is in close contact with the outer wall of the sealing ring 8 on the inner wall of the connecting sleeve 3, laying the foundation for waterproof sealing. When the locking block 7 reaches the fixed position, the slot 2 on the inner wall of the sleeve 1 will also align with the position of the fixing pin 4 on the connecting sleeve 3. At this time, no longer pull the fixing pin 4. The elasticity of the compression spring 5 pushes the fixing pin 4 to automatically insert into the slot 2, realizing the firm locking of the sleeve 1 and the connecting sleeve 3. If disassembly is required, simply pull the end of the fixing pin 4 again. The compression spring 5 will contract and drive the fixing pin 4 to disengage from the slot 2. Then, rotate the connecting sleeve 3 in the opposite direction to separate them.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
