[0001] This utility model relates to the field of cable connector technology, and in particular to a quick-connect shielded cable connector for mining applications. Background Technology

[0002] Mining shielded cable connectors are key components in mine power transmission and control systems. They are mainly used to connect shielded cables to ensure stable and safe transmission of power and signals in complex underground environments.

[0003] Existing shielded cables for mining are limited by their length, and multiple cables usually need to be connected with joints in mines to ensure the power supply needs of the mine. However, due to the influence of mechanical vibration and equipment pulling, the joint connection is usually connected with tape or bolts to ensure stability. In actual use, it is not convenient to quickly disassemble and replace the connected cables after partial damage. Therefore, a quick-connect shielded cable joint for mining is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-connect shielded cable connector for mining, which aims to improve the problem that the connected cable is not easy to quickly disassemble and replace after damage in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-connect shielded cable connector for mining applications includes a cable 1 and a cable 2. The ends of the cable 1 and the cable 2 are respectively provided with an interface 2 and an interface 1. Both the cable 1 and the cable 2 are fitted with sleeves. The outer circumferences of the two sleeves are respectively threaded to a threaded tube 1 and a threaded tube 2. The outer circumference of the threaded tube 1 is fixedly connected to an outer ring 1, and the outer circumference of the threaded tube 2 is fixedly connected to an outer ring 2. A connecting rod is fixedly connected to the middle of the outer ring 1. A compression spring 2 is fitted around the outer circumference of the connecting rod, and a locking assembly is installed around the outer circumference of the connecting rod.

[0007] The engaging assembly includes a push plate, which is slidably connected to the outer periphery of the connecting rod. A plug rod is fixedly connected to the middle of the push plate, and the other end of the plug rod passes through the outer ring.

[0008] As a further description of the above technical solution:

[0009] The sleeve has a protrusion in the middle, and an injection port is fixedly connected to the middle of the protrusion. A fixing ring is fixedly connected to the middle of the injection port. A round rod is slidably connected to the middle of the fixing ring. A baffle is fixedly connected to one end of the round rod, and a blocking block is fixedly connected to the other end of the round rod. A compression spring is sleeved on the outer periphery of the round rod.

[0010] As a further description of the above technical solution:

[0011] Both cable one and cable two are fitted with sealing rings on their outer periphery, and the two sealing rings are respectively located in the middle of the two sleeves;

[0012] As a further description of the above technical solution:

[0013] A collar is fitted around the outer periphery of the second interface, and a sealing gasket is installed in the middle of the collar, with the sealing gasket in contact with the inner wall of the first threaded tube.

[0014] As a further description of the above technical solution:

[0015] A sealing gasket is installed between the threaded pipe 2 and the interface 1;

[0016] As a further description of the above technical solution:

[0017] A groove is provided in the middle of the outer ring two, and the push plate is slidably connected to the middle of the groove;

[0018] As a further description of the above technical solution:

[0019] The outer ring two has a through hole in the middle, which is connected to the groove, and the insertion rod is slidably connected to the middle of the through hole;

[0020] As a further description of the above technical solution:

[0021] The compression spring is located between the resistance block and the fixing ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, while the second interface is inserted into the first interface, the push plate slides on the outer periphery of the connecting rod and inserts the push plate into the middle of the second outer ring. After the push plate is released, under the push of the second compression spring, the push plate drives the insertion rod to insert into the middle of the second outer ring. In this way, while improving the stability of the connection, the first cable and the second cable can be quickly separated by squeezing and pulling.

[0024] 2. In this utility model, by inserting the glue injection end into the glue injection port and pushing the baffle, the baffle is separated from the fixing ring, so that the glue can be injected into the protrusion. Then, the glue fills the gap between the two sleeves and the first and second cables, improving the sealing performance, preventing moisture from entering through the gap, and avoiding short circuit.

[0033] 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.

[0034] Reference Figure 1 , Figure 2 and Figure 6This utility model provides an embodiment of a quick-connect shielded cable connector for mining applications, comprising a cable 1 and a cable 2. The ends of the cable 1 and cable 2 are respectively provided with an interface 2 18 and an interface 13. A sleeve 3 is fitted around the outer periphery of both the cable 1 and cable 2. A threaded tube 6 and a threaded tube 7 are threadedly connected to the outer periphery of the two sleeves 3, respectively. An outer ring 8 is fixedly connected to the outer periphery of the threaded tube 6, and an outer ring 9 is fixedly connected to the outer periphery of the threaded tube 7. A connecting rod 14 is fixedly connected to the middle of the outer ring 8. A compression spring 26 is sleeved on the outer periphery of the connecting rod 14. A locking assembly is installed on the outer periphery of the connecting rod 14. The locking assembly includes a push plate 10, which is slidably connected to the outer periphery of the connecting rod 14. An insert rod 15 is fixedly connected to the middle of the push plate 10. The other end of the insert rod 15 passes through the outer ring 9. A groove 11 is opened in the middle of the outer ring 9. The push plate 10 is slidably connected to the middle of the groove 11. A through hole 12 is opened in the middle of the outer ring 9. The through hole 12 is connected to the groove 11. The insert rod 15 is slidably connected to the middle of the through hole 12. First, the threaded tube 6 and threaded tube 7 are fixed to the outer periphery of cable 1 and cable 2 by two sleeves 3. At the same time, interface 2 18 and interface 1 13 are inserted. Interface 1 13 will be inserted into the middle of threaded tube 6, thus ensuring the safety of the connection. Simultaneously, during the insertion, the push plate 10 slides on the outer periphery of the connecting rod 14 and compresses the compression spring 2 26, so that the push plate 10 can drive the insertion rod 15 into the groove 11. After the insertion is completed, the push plate 10 is released, so that the compression spring 2 26 pushes the push plate 10 to return to its original position, so that the push plate 10 can drive the insertion rod 15 into the through hole 12, thereby improving the stability of the connection between interface 2 18 and interface 1 13 and preventing separation due to vibration and pulling. At the same time, when replacement is required, the push plate 10 is pressed to drive the insertion rod 15 to slide out from the middle of the through hole 12, so that interface 2 18 and interface 1 13 can be quickly separated, improving the efficiency of disassembly and replacement.

[0035] Reference Figure 5The sleeve 3 has a protrusion 5 in the middle, and a glue injection port 4 is fixedly connected to the middle of the protrusion 5. A fixing ring 21 is fixedly connected to the middle of the glue injection port 4. A round rod 24 is slidably connected to the middle of the fixing ring 21. A baffle 22 is fixedly connected to one end of the round rod 24, and a blocking block 25 is fixedly connected to the other end of the round rod 24. A compression spring 23 is sleeved on the outer periphery of the round rod 24. After fixing threaded tube 6 and threaded tube 7, insert the glue injection end into the middle of the glue injection port 4 and push the baffle 22 to separate the baffle 22 from the fixing ring 21. This allows the glue to enter the gap between the two sleeves 3 and the first and second cables 1 and 2, filling the gap. After the glue solidifies, the sealing between the two sleeves 3 and the first and second cables 1 and 2 is improved, preventing moisture from contacting the connector through the gap and improving the safety of the cable. At the same time, as the baffle 22 moves, it will drive the stop block 25 through the round rod 24 to squeeze the spring 23. After the glue injection end is pulled out, the spring 23 can push the stop block 25, causing the baffle 22 to reset and block the gap of the fixing ring 21, thereby preventing the glue from flowing out through the glue injection port 4.

[0036] Reference Figure 3 and Figure 4 Both cable 1 and cable 2 are fitted with sealing rings 16 on their outer circumferences. The two sealing rings 16 are located in the middle of the two sleeves 3. A collar 17 is fitted around the outer circumference of interface 2 18, and a sealing gasket 19 is installed in the middle of the collar 17. The sealing gasket 19 contacts the inner wall of the threaded tube 6. A sealing gasket 20 is installed between the threaded tube 2 7 and interface 1 13. A compression spring 23 is located between the stop block 25 and the fixing ring 21. The sealing rings 16 prevent glue from overflowing from the rear end of the sleeves 3, reducing waste. Simultaneously, the sealing gaskets 19 and 20 allow glue to flow onto interface 2 18, ensuring normal use. Furthermore, after interface 2 18 and interface 1 13 are inserted, the sealing gasket 20 further enhances the sealing of the connection, preventing dust and moisture from affecting the connection and ensuring safety and service life.

[0037] Working principle: First, insert interface 2 18 and interface 1 13. At the same time as insertion, push plate 10 slides on the outer periphery of connecting rod 14, so that push plate 10 can drive insertion rod 15 into groove 11. Release push plate 10, so that compression spring 26 pushes push plate 10 to reset, so that insertion rod 15 can be inserted into through hole 12, thereby avoiding separation due to vibration and pulling. At the same time, push plate 10 drives insertion rod 15 to slide out from the middle of through hole 12, so that interface 2 18 and interface 1 13 can be quickly separated, improving disassembly and replacement efficiency.

[0038] After fixing threaded tube 6 and threaded tube 7, insert the glue injection end into the middle of the glue injection port 4 and push the baffle 22 to separate the baffle 22 from the fixing ring 21, so that the glue can enter the gap between the two sleeves 3 and the cable 1 and cable 2 to fill the gap, prevent moisture from contacting the plug interface through the gap, and improve the safety of cable use.

[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
