Description
Technical Field
[0001] This utility model relates to the field of cable connector technology, and in particular to a connector for supporting cables. Background Technology
[0002] Cable connectors are key components used to achieve mechanical and electrical connections between cables or between cables and equipment. They are typically made of metal and plastic and possess good conductivity, mechanical strength, and insulation properties. Their interface shapes vary, including circular, rectangular, and board-to-board, and their installation methods include plug-in, screw-locking, and lead-in types. They not only ensure reliable power or signal transmission but also protect cables from external environmental influences, making them an indispensable component in electronic and electrical equipment.
[0003] Cable connector-related equipment includes crimping pliers, wire strippers, and heat shrink tubing heating devices. The wire stripper precisely removes the cable sheath, exposing the internal conductors. The crimping pliers apply pressure to firmly press the connector terminals onto the conductors, forming a stable electrical connection. The heat shrink tubing heating device heats the heat shrink tubing fitted over the connection, causing it to shrink tightly and provide insulation and protection. Its working principle is based on the theory of metal-to-metal contact conductivity. The connector's metal contacts are in close contact with the cable conductors, utilizing the excellent conductivity of metal to achieve low-resistance transmission of current or signals. Simultaneously, the connector's insulating material isolates different conductors, preventing short circuits and ensuring the safe and stable operation of electrical equipment.
[0004] Ordinary cable-bearing connectors have several shortcomings. In terms of protective structure, some connectors have rudimentary dustproof and waterproof sealing processes, poor weather resistance of the sealing ring material, and are prone to aging and cracking after long-term use. Furthermore, the joints are not tightly sealed, failing to effectively resist heavy rain and strong sandstorms, leading to internal components becoming damp and oxidized, accumulating dust, and short circuits. Regarding connection stability, their mechanical connection structure design lacks vibration-damping mechanisms, relying solely on simple clips or ordinary threads for fastening under load. When faced with mechanical vibration and dynamic loads, the clips are prone to fatigue and breakage, and the threads are prone to loosening and stripping, causing the connector to fall off and the cable to become loose. This not only affects the continuity of power and signal transmission but can also cause equipment failures or even safety accidents. Therefore, a new type of cable-bearing connector is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a cable-bearing connector, which aims to improve the problems of insufficient protection and unstable connection in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cable-bearing connector includes an upper housing, a snap-fit sleeve slidably connected to the inner side of the upper housing, a connecting sleeve slidably connected to the inner side of the snap-fit sleeve, a plurality of steel balls slidably connected inside the connecting sleeve, a fixing sleeve slidably connected to the front end of the snap-fit sleeve, an insulating sleeve slidably connected to the front end of the fixing sleeve, a male connector tube slidably connected inside the insulating sleeve slidably, a male connector fixedly connected to the rear end of the male connector tube, a female connector slidably connected inside the connecting sleeve, the male connector and the female connector being mated and connected, and a locking assembly threadedly connected to the upper end of the upper housing. As a further description of the above technical solution: The locking assembly includes a pressing rod, a fixing block is fixedly connected to the outer side of the pressing rod, a nut is slidably connected to the lower end of the fixing block, a grommet screw is connected to the internal thread of the nut, a snap-fit groove is fixedly connected to the lower end of the grommet screw, a cylindrical sleeve is fixedly connected to the lower end of the snap-fit groove, a fixing plate is fixedly connected to the inner side of the cylindrical sleeve, and a snap-fit strip is rotatably connected to the outer side of the snap-fit groove. As a further description of the above technical solution: The lower end of the upper outer shell is slidably connected to the lower outer shell, the outer side of the male connector is slidably connected to the dust cover, the inner side of the fixing sleeve is fixedly connected to the limit tube, and the inner side of the buckle groove is fixedly connected to the pressing rod. As a further description of the above technical solution: A sealing ring is fixedly connected to the rear end of the buckle sleeve, and a limit tube is fixedly connected to the front end of the buckle sleeve. As a further description of the above technical solution: An insulating sleeve is fixedly connected to the rear end of the connecting sleeve, and a base is fixedly connected to the lower end of the cylindrical sleeve. As a further description of the above technical solution: The female connector is fixedly connected to the rear end of the female connector, and the inner side of the insulating sleeve is provided with screw threads. As a further description of the above technical solution: The upper end of the fixed plate is fixedly connected to a second spring, the base has a moving groove inside, and the rear end of the first spring is fixedly connected to a buckle sleeve. As a further description of the above technical solution: A spring is slidably connected to the outer side of the connecting sleeve, and a pressing rod is slidably connected to the inner side of the spring.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the snap-fit sleeve and the connecting sleeve are slidably connected. Sliding the snap-fit sleeve to the left compresses the first spring, and at the same time, the steel ball inside the connecting sleeve unlocks, allowing the female head to be connected to the connecting sleeve. Releasing the snap-fit sleeve and the first spring rebounds. Since the first spring and the snap-fit sleeve are fixedly connected, the snap-fit sleeve returns to its original position and locks the steel ball, while simultaneously locking the female head, ensuring the reliability and safety of the cable load-bearing connection, improving on-site installation efficiency, and making the cable connection operation both convenient and stable.
[0008] 2. In this utility model, pressing the pressing rod causes it to move downwards. The downward movement of the pressing rod causes the second spring to contract. Since the latching rod and the latching groove are fixedly connected, and the latching groove and the pressing rod are fixedly connected, the downward movement of the pressing rod causes the latching rod to retract and enter the cylindrical sleeve, thus completing the unlocking. This greatly shortens the time and cost of maintenance and repair, and improves work efficiency and safety. Attached Figure Description

[0011] 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.
[0012] Reference Figure 3and Figure 4 This utility model provides an embodiment of a cable-bearing connector, including an upper shell 1. The upper shell 1 constitutes the top protective structure of the connector, which can resist external impact, dust and moisture intrusion, and provide a stable working environment for internal precision components. A snap-fit sleeve 7 is slidably connected to the inner side of the upper shell 1. The snap-fit sleeve 7 can slide flexibly along the inner side of the upper shell 1. During the cable connection process, the steel ball 9 is locked and unlocked by its sliding, ensuring the reliability and convenience of the connection. A lower shell 2 is slidably connected to the lower end of the upper shell 1. The lower shell 2 and the upper shell 1 cooperate to form a complete protective shell. The sliding connection design of the two facilitates quick disassembly and assembly, and facilitates internal inspection and maintenance.
[0013] A sealing ring 15 is fixedly connected to the rear end of the snap-fit sleeve 7. The sealing ring 15 fits tightly against the connection between the snap-fit sleeve 7 and the upper outer shell 1, effectively preventing external liquids and dust from entering the connector and avoiding electrical connection failures caused by environmental factors. A limiting tube 16 is fixedly connected to the front end of the snap-fit sleeve 7. The limiting tube 16 can limit the sliding stroke of the snap-fit sleeve 7 to prevent it from sliding excessively and affecting the locking function of the steel ball 9, ensuring the accuracy of the connection operation. A connecting sleeve 10 is slidably connected to the inner side of the snap-fit sleeve 7. Under the constraint of the snap-fit sleeve 7, the connecting sleeve 10 can realize linkage with the steel ball 9, providing precise insertion guidance and locking space for the female head 14 during cable connection. A spring 8 is slidably connected to the outer side of the connecting sleeve 10. The spring 8 has good elastic restoring force. When the snap sleeve 7 slides, the spring 8 is deformed by pressure. After the snap sleeve 7 is released, the spring 8 quickly rebounds, pushing the snap sleeve 7 to reset, so that the steel ball 9 relocks the female head 14, ensuring the stability of the connection. The snap sleeve 7 is fixedly connected to the rear end of the spring 8. This fixing method ensures that the elastic force of the spring 8 can be accurately transmitted to the snap sleeve 7, making the entire locking process smooth and reliable. An insulating sleeve 28 is fixedly connected to the rear end of the connecting sleeve 10. The insulating sleeve 28 can effectively isolate the connecting sleeve 10 from external conductors, prevent leakage risk, and ensure the safety of operators and the normal operation of equipment. Multiple steel balls 9 are slidably connected inside the connecting sleeve 10. The steel balls 9 are evenly distributed inside the connecting sleeve 10. When the female head 14 is inserted, the steel balls 9 can move flexibly and lock into the locking groove of the female head 14 to form a multi-point locking, which greatly enhances the load-bearing capacity and tensile strength of the cable connection. The front end of the snap sleeve 7 is slidably connected to the fixing sleeve 6. The fixing sleeve 6 can slide along the front end of the snap sleeve 7. During the cable connection process, it plays an auxiliary positioning and guiding role to ensure the accurate docking of the insulating sleeve 5 and the male connector 3. The inner side of the fixing sleeve 6 is fixedly connected to the limiting tube 16. The limiting tube 16 further limits the sliding range of the fixing sleeve 6 to ensure its stability during the auxiliary positioning process. The front end of the fixed sleeve 6 is slidably connected to an insulating sleeve 5. The insulating sleeve 5 can isolate the male connector 3 from external conductors, prevent short circuits and leakage, and ensure the safety of cable power transmission. The inner side of the insulating sleeve 5 is provided with screw threads 12. The screw threads 12 are designed to make it easy to tightly screw with the male connector 3 to achieve a stable connection between the two, and also to facilitate disassembly and replacement later. The male connector 3 is slidably connected inside the insulating sleeve 5. As an important component of the cable electrical connection, the male connector 3 is used to transmit current or signals. Its sliding connection with the insulating sleeve 5 facilitates installation and debugging. A dust cover 4 is slidably connected to the outside of the male connector 3. The dust cover 4 can cover the male connector 3 when the connector is not in use, preventing dust and debris from entering and avoiding poor contact caused by the accumulation of foreign objects. A male connector 13 is fixedly connected to the rear end of the male connector 3. The male connector 13 serves as the mating end of the cable connection and precisely matches with the female connector 14 to achieve electrical connection between the cables. The female connector 14 is slidably connected inside the connecting sleeve 10. The female connector 14 slides inside the connecting sleeve 10 and achieves a stable connection with the male connector 13 through locking with the steel ball 9. A female connector 11 is fixedly connected to the rear end of the female connector 14. The female connector 11 corresponds to the male connector 3 in function and is responsible for the electrical connection and signal transmission at the other end of the cable. The male connector 13 and the female connector 14 are paired and connected. The two achieve precise docking through a precise structural design to ensure stable and reliable electrical performance after the cable connection. The upper end of the upper outer shell 1 is threadedly connected to a locking assembly, which includes a pressing rod 17. The pressing rod 17 is the core component for unlocking. By pressing with external force, the entire locking assembly can be quickly activated, triggering the separation of the upper outer shell 1 and the lower outer shell 2. A fixing block 18 is fixedly connected to the outside of the pressing rod 17. The fixing block 18 provides a stable support base for the pressing rod 17, ensuring that the pressing rod 17 remains stable when under force, and avoiding shaking that could affect the accuracy of the unlocking operation. A nut 19 is slidably connected to the lower end of the fixing block 18. The nut 19 can slide flexibly along the lower end of the fixing block 18. By tightening or loosening, the entire locking assembly can be fastened or separated from the upper outer shell 1, thereby controlling the opening and closing state of the upper outer shell 1 and the lower outer shell 2. The internal thread of the nut 19 is connected to a nut screw 20. The thread engagement between the nut screw 20 and the nut 19 can finely adjust the fixing position of the nut 19, enhance the stability and adaptability of the locking assembly installation, and ensure that the upper outer shell 1 and the lower outer shell 2 are tightly fixed. The lower end of the nut screw 20 is slidably connected to a latching groove 27. The latching groove 27 can slide along the lower end of the nut screw 20. After the nut 19 is fixed to the nut screw 20, the latching groove 27 becomes a key component connecting the upper outer shell 1 and the lower outer shell 2. The outer shell is locked by locking the corresponding structure. A pressing rod 17 is fixedly connected to the inner side of the latching groove 27. This connection method allows the action of the pressing rod 17 to directly drive the latching groove 27 to move, ensuring that the latching groove 27 quickly disengages from the locked position of the outer shell when unlocking. The lower end of the snap-fit groove 27 is slidably connected to a cylindrical sleeve 26. The cylindrical sleeve 26 provides guidance and limit for the sliding of the snap-fit groove 27, ensuring that the snap-fit groove 27 maintains a straight trajectory during movement and avoiding deviation that could lead to unlocking failure. The lower end of the cylindrical sleeve 26 is fixedly connected to a base 24. The base 24 provides an installation foundation for the entire locking assembly and is firmly fixed to the upper end of the connector housing 1, ensuring that the locking assembly will not loosen when subjected to force. The base 24 has a movable groove 23 inside, which provides space for the up and down movement of the pressing rod 17 and limits the range of movement of the pressing rod 17 to ensure that the pressing rod 17 moves accurately during the unlocking operation and does not move excessively. The inner side of the cylindrical sleeve 26 is fixedly connected to a fixing plate 22, which is used to fix one end of the second spring 21 and provide a stable support point for the second spring 21 to ensure that the second spring 21 remains stable during compression and rebound. A second spring 21 is fixedly connected to the upper end of the fixed plate 22. The second spring 21 has good elasticity and is in a compressed and stored state under normal conditions. When the pressing rod 17 is pressed down, the second spring 21 is further compressed. After the pressing rod 17 is released, the second spring 21 quickly rebounds and pushes the pressing rod 17 to reset, so that the locking assembly returns to its initial state. The pressing rod 17 is slidably connected to the inner side of the second spring 21. This connection method allows the elastic force of the second spring 21 to act precisely on the pressing rod 17, ensuring that the pressing rod 17 moves smoothly during unlocking and resetting. A latching strip 25 is rotatably connected to the outer side of the latching groove 27. The latching strip 25 can flexibly latch or disengage from the connection part of the upper outer shell 1 and the lower outer shell 2 through the rotatable connection with the latching groove 27. When the nut 19 is tightened, the latching strip 25 supports the connection port of the outer shell to achieve locking. When the pressing rod 17 is pressed, the latching strip 25 moves with the latching groove 27, quickly releasing the constraint on the outer shell and achieving quick unlocking. Reference Figure 1 and Figure 2 The locking assembly includes a pressing rod 17, which is the core component for unlocking. The pressing rod 17 is pressed by external force to achieve a rapid action of the entire locking assembly, triggering the separation of the upper outer shell 1 and the lower outer shell 2. A fixing block 18 is fixedly connected to the outside of the pressing rod 17. The fixing block 18 provides a stable support base for the pressing rod 17, ensuring that the pressing rod 17 remains stable when subjected to force, and avoiding shaking that affects the accuracy of the unlocking operation. The lower end of the fixing block 18 is slidably connected to a nut 19. The nut 19 can slide flexibly along the lower end of the fixing block 18. By tightening or loosening, the entire locking assembly can be fastened or separated from the upper outer shell 1, thereby controlling the opening and closing state of the upper outer shell 1 and the lower outer shell 2. The internal thread of the nut 19 is connected to a nut screw 20. The thread engagement between the nut screw 20 and the nut 19 can finely adjust the fixing position of the nut 19, enhance the stability and adaptability of the locking assembly installation, and ensure that the upper outer shell 1 and the lower outer shell 2 are tightly fixed. The lower end of the nut screw 20 is slidably connected to a latching groove 27. The latching groove 27 can slide along the lower end of the nut screw 20. After the nut 19 is fixed to the nut screw 20, the latching groove 27 becomes a key component connecting the upper outer shell 1 and the lower outer shell 2. The outer shell is locked by locking the corresponding structure. A pressing rod 17 is fixedly connected to the inner side of the latching groove 27. This connection method allows the action of the pressing rod 17 to directly drive the latching groove 27 to move, ensuring that the latching groove 27 quickly disengages from the locked position of the outer shell when unlocking. The lower end of the latching groove 27 is slidably connected to a cylindrical sleeve 26. The cylindrical sleeve 26 provides guidance and limit for the sliding of the latching groove 27, ensuring that the latching groove 27 maintains a straight trajectory during movement and avoiding deviation that could lead to unlocking failure. The lower end of the cylindrical sleeve 26 is fixedly connected to a base 24. The base 24 provides an installation foundation for the entire latching assembly and is firmly fixed to the upper end of the connector housing 1, ensuring that the latching assembly will not loosen when subjected to force. The base 24 has a movable groove 23 inside, which provides space for the up and down movement of the pressing rod 17 and limits the range of movement of the pressing rod 17 to ensure that the pressing rod 17 moves accurately during the unlocking operation and does not move excessively. The inner side of the cylindrical sleeve 26 is fixedly connected to a fixing plate 22, which is used to fix one end of the second spring 21 and provide a stable support point for the second spring 21 to ensure that the second spring 21 remains stable during compression and rebound. A second spring 21 is fixedly connected to the upper end of the fixed plate 22. The second spring 21 has good elasticity and is in a compressed and stored state under normal conditions. When the pressing rod 17 is pressed down, the second spring 21 is further compressed. After the pressing rod 17 is released, the second spring 21 quickly rebounds, pushing the pressing rod 17 to reset and restoring the locking assembly to its initial state. The pressing rod 17 is slidably connected to the inner side of the second spring 21. This connection method allows the elastic force of the second spring 21 to act precisely on the pressing rod 17, ensuring that the pressing rod 17 moves smoothly during unlocking and resetting. A latching strip 25 is rotatably connected to the outer side of the latching groove 27. The latching strip 25 can flexibly latch or disengage from the connection part of the upper outer shell 1 and the lower outer shell 2 through the rotatable connection with the latching groove 27. When the nut 19 is tightened, the latching strip 25 supports the outer shell connection port to achieve locking. When the pressing rod 17 is pressed, the latching strip 25 moves with the latching groove 27, quickly releasing the constraint on the outer shell and achieving quick unlocking. Working principle: Connect the cable through male connector 13 and female connector 14. Slide the buckle sleeve 7 to the left, and the steel ball 9 inside the connecting sleeve 10 can move up and down, allowing the female connector 14 to enter the connecting sleeve 10. Release the buckle sleeve 7, and the spring 8 will return the buckle sleeve 7 to its original position, locking the steel ball 9. The locked steel ball 9 locks the female connector 14, achieving a stable connection. Slide the buckle sleeve 7 to the left again to unlock the steel ball 9, thus unlocking the female connector 14.
[0014] The locking assembly passes through the upper outer shell 1 and the lower outer shell 2. The latching strip 25 supports the connection port while the nut 19 is tightened, fixing the upper outer shell 1 and the lower outer shell 2 and realizing the function of protecting the connector. After loosening the nut 19, press the pressing rod 17. The pressing rod 17 moves downward and enters the sliding groove, compressing the spring 21. The pressing rod 17 moves downward and drives the latching strip 25 into the gap between the cylindrical sleeve 26 and the pressing rod 17, realizing the quick unlocking function.
