Abstract
Description
Technical Field
[0001] This utility model relates to a cable connector, and more particularly to a cable connector for use with multiple cables in the field of cable connectors. Background Technology
[0002] Cable joints, also known as cable ends, are the points where sections of a cable must be connected to form a continuous line after the cable has been laid. Cable joints in the middle of a cable line are called intermediate joints, while cable joints at both ends of the line are called terminal joints.
[0003] The specification of Chinese Patent Publication No. CN221947852U discloses a cable connector for multiple cables. In use, multiple cables pass through the device, and a rotating disk is rotated. The rotating disk drives a threaded rod to rotate. The threaded rod is threadedly connected to a threaded groove, and the threaded rod can drive a compression ring to move towards the center to compress and fix the cables. This device can compress and fix multiple cables, has strong sealing performance, is simple to operate, convenient to use, has an ingenious structure, is highly practical, and is conducive to promotion.
[0004] However, the above patent still has the following problems in actual application: When using the above patent, multiple cables are passed through the cable joint and then the multiple cables are squeezed and fixed by the compression ring. However, the compression of multiple cables means that the outer shells of multiple cables are pressed together. If the compression is excessive, the outer sheaths of multiple cables may be worn due to mutual friction and excessive local pressure, increasing the risk of leakage or short circuit. In addition, the tight pressing of multiple cables will also hinder the dissipation of heat and accelerate the aging of the cables. Utility Model Content
[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that in the existing patents, multiple cables are passed through the cable joint and fixed during use. During fixing, the multiple cables are close to each other. This fixing method may not only cause wear on the cable sheath, increasing the risk of leakage or short circuit, but the close contact of multiple cables will also hinder heat dissipation and accelerate the aging of the cables.
[0006] To address the aforementioned problems, this utility model provides a cable connector for multiple cables, comprising an installation tube, an inner cavity of which is provided with a positioning rod, and multiple partitions fixedly connected between the outer surface of the positioning rod and the inner wall of the installation tube. A pad is fixedly connected between two adjacent partitions. An adjusting sleeve and an adjusting plate are rotatably sleeved on the outside of the installation tube. The outer circumferential surface of the adjusting plate is fixedly connected to the inner wall of the adjusting sleeve. Multiple adjusting grooves, each corresponding to a pad, are chiseled on the outer surface of the adjusting plate. An installation rod is provided within each adjusting groove. Adjusting rods are fixedly connected to both ends of the installation rods. The ends of the two adjusting rods facing the installation tube movably penetrate the installation tube and are jointly fixedly connected to a pressure plate. Two L-shaped installation plates are fixedly connected to the outer surface of the installation tube. A compression spring is fixedly connected to the corresponding end of each of the two installation plates. A limit plate is fixedly connected to the end of the compression spring furthest from the installation plate. Multiple limit holes are chiseled at both ends of the adjusting sleeve. Insert rods are provided at the ends of the two installation plates furthest from each other. The corresponding ends of the two insert rods movably penetrate the installation plate and the compression spring and are fixedly penetrated through the limit plate. The ends of the insert rods furthest from the installation plate movably penetrate the adjacent limit hole.
[0007] In the aforementioned cable joint for multiple cables, this application divides the installation pipe into multiple independent spaces using partitions and positioning rods, allowing the cables to be separated into independent chambers. Multiple cables are then simultaneously positioned and fixed, effectively preventing mutual compression and friction between the cables, reducing insulation wear caused by vibration or thermal expansion, and extending cable lifespan. The position of the pressure plate is adjusted by controlling the movement of the adjusting rod, facilitating the positioning and fixing of cables of different diameters, thus significantly improving the practicality of this cable joint.
[0008] As a further improvement of this application, multiple partitions are arranged in a circular array around the central axis of the positioning rod, the end of the pad away from the positioning rod is an arc surface, and the pad is elastic.
[0009] As a further improvement to this application, the adjustment groove is arc-shaped, and the distances between the two ends of the adjustment groove and the outer wall of the mounting pipe are different.
[0010] As a further improvement of this application, two mounting plates are located at the front and rear ends of the adjusting sleeve, respectively, and the two mounting plates are symmetrically distributed. A handle is fixedly connected to the outer surface of the adjusting sleeve.
[0011] As another improvement of this application, the positioning rod has a hollow structure, and multiple ventilation holes are drilled on the outer surfaces of both the pad and the positioning rod.
[0012] As a further improvement to this application, multiple ventilation holes are arranged in a circular array around the central axis of the positioning rod, and multiple spiral blades are fixedly connected to the inner wall of the positioning rod.
[0013] In summary, in practical applications, multiple cables are inserted into the installation conduit, separated by a partition. Rotating the adjusting sleeve causes the adjusting plate to rotate, allowing the installation rod to slide within the adjusting groove. This movement of the adjusting rod moves the pressure plate, bringing it into contact with the cable surface and thus limiting and fixing the cable connection. Inserting the insertion rod into the adjacent limiting hole further limits and fixes the adjusting sleeve. This process effectively compresses and fixes multiple cables, preventing mutual compression and friction between them, reducing insulation wear caused by vibration or thermal expansion, and extending cable lifespan. Controlling the movement of the adjusting rod adjusts the position of the pressure plate, facilitating the limiting and fixing of cables of different diameters, and significantly improving the practicality of this cable connector.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0024] First implementation method:
[0025] Figure 1 and Figure 2The diagram shows a cable connector for multiple cables, including an installation tube 1. The inner cavity of the installation tube 1 is provided with a positioning rod 2. Multiple partitions 3 are fixedly connected between the outer surface of the positioning rod 2 and the inner wall of the installation tube 1. The positioning rod 2 and the partitions 3 divide the interior of the installation tube 1 into multiple spaces, allowing multiple cables to be placed in these spaces, effectively preventing them from touching each other. A pad 4 is fixedly connected between adjacent partitions 3. The multiple partitions 3 are arranged in a circular array around the central axis of the positioning rod 2. The end of the pad 4 away from the positioning rod 2 is curved and elastic. The pad 4 and a movable pressure plate 10 limit and fix the cables. The elastic pad 4 protects the cables and effectively prevents them from being excessively squeezed.
[0026] Figure 1 , Figure 2 , Figure 3 and Figure 4 The diagram shows that an adjusting sleeve 5 and an adjusting plate 6 are rotatably fitted around the installation tube 1. A handle is fixedly connected to the outer surface of the adjusting sleeve 5, which facilitates the rotation of the adjusting sleeve 5. The outer ring surface of the adjusting plate 6 is fixedly connected to the inner wall of the adjusting sleeve 5. Rotating the adjusting sleeve 5 can drive the adjustment plate 6 to rotate. Multiple adjusting grooves 7, each corresponding to multiple pads 4, are carved on the outer surface of the adjusting plate 6. The adjusting grooves 7 are arc-shaped, and the distances between the two ends of the adjusting grooves 7 and the outer wall of the installation tube 1 are different. An installation rod 8 is provided in the adjusting groove 7. Adjusting rods 9 are fixedly connected to both the front and rear ends of the installation rod 8. The ends of the two adjusting rods 9 facing the installation tube 1 both movably pass through the installation tube 1 and are jointly fixedly connected to a pressure plate 10. The installation rod 8 moves along the arc of the adjusting groove 7 in the adjusting groove 7. By being limited by the installation tube 1, the adjusting rod 9 is forced to move only in a straight line. The adjusting rod 9 drives the pressure plate 10 to move towards or away from the positioning rod 2.
[0027] Figure 1 and Figure 5The diagram shows that two L-shaped mounting plates 11 are fixedly connected to the outer surface of the mounting tube 1. The two mounting plates 11 are located at the front and rear ends of the adjusting sleeve 5, respectively, and are symmetrically distributed. A compression spring 12 is fixedly connected to one end of each mounting plate 11. A limit plate 13 is fixedly connected to the end of the compression spring 12 away from the mounting plate 11. Multiple limit holes 14 are drilled at both the front and rear ends of the adjusting sleeve 5. A rod 15 is provided at the end of each mounting plate 11 away from the other. The corresponding ends of the two rods 15 can movably pass through the mounting plate 11 and the compression spring 12. The fixed through-limiting plate 13 is fixed, and the end of the insertion rod 15 away from the mounting plate 11 moves through the adjacent limiting hole 14. Before rotating the adjusting sleeve 5, the insertion rod 15 needs to be pulled outward to cause the compression spring 12 to retract outward and the insertion rod 15 to disengage from the limiting hole 14. Then, the adjusting sleeve 5 is rotated. After the cable is squeezed and fixed by the pressure plate 10, the insertion rod 15 is released to allow the compression spring 12 to return to its original position, and the insertion rod 15 is driven to insert into the limiting hole 14, thereby limiting and fixing the adjusting sleeve 5, making it difficult for the adjusting sleeve 5 to rotate, thereby improving the stability of the pressure plate 10 in limiting the cable.
[0028] In use, multiple cables are inserted into the installation tube 1, separated by the partition 3. Pulling the insertion rod 15 outward causes the compression spring 12 to contract outward, disengaging the insertion rod 15 from the limiting hole 14. Then, rotating the adjusting sleeve 5 rotates the adjusting plate 6, causing the installation rod 8 to slide within the adjusting groove 7, thus moving the adjusting rod 9 and the pressure plate 10. This causes the pressure plate 10 to come into contact with the surface of the cable, thereby limiting and fixing the cable connection. Then, the insertion rod 5 is inserted into the adjacent limiting hole 14 to limit and fix the adjusting sleeve 5. This completes the compression and fixing of multiple cables, effectively preventing mutual compression and friction between the cables, reducing insulation wear caused by vibration or thermal expansion, extending the cable's service life, and facilitating the limiting and fixing of cables of different diameters, effectively improving the practicality of this cable connector.
[0029] Second implementation method:
[0030] This embodiment adds a ventilation hole 16 and a spiral blade 17 to the first embodiment, while the rest remains the same as the first embodiment.
[0031] Figure 6 and Figure 7 As shown: the positioning rod 2 is a hollow structure, and multiple ventilation holes 16 are drilled on the outer surfaces of both the pad 4 and the positioning rod 2. The multiple ventilation holes 16 are arranged in a ring array around the central axis of the positioning rod 2, and multiple spiral blades 17 are fixedly connected to the inner wall of the positioning rod 2.
[0032] When in use, when the outside wind blows, the air enters the positioning rod 2 and forms a swirling flow through multiple spiral blades 17, thereby enhancing the ventilation effect. The multiple ventilation holes 16 dissipate heat from the surface of the cable, effectively preventing the cable connection from getting too hot, thus extending the service life of the cable.
[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
