Description

Technical Field

[0001] The utility model relates to the field of communication wire connection, in particular to a communication wire connection device. Background Art

[0002] Covered wire is also called field covered wire, which is a kind of communication wire. It is mostly used in harsh field operation environments such as military field operations, mining, exploration, etc., and needs to have strong tensile and compressive resistance. Covered wire is generally connected to telephones, teletransmission equipment, and wired communication equipment, and is mainly used for audio telephone and telegraph communication.

[0003] At present, since the covered wire itself has a certain mechanical strength, during field operations, one end of the covered wire is generally connected to a push-type terminal, or the covered wire is wrapped around a terminal stud and connected to the terminal stud using a locking nut to fix the covered wire.

[0004] However, the push-type terminal connection method can withstand less tensile force, and the terminal stud and lock nut connection method requires the use of professional tools, which is not convenient for rapid deployment. Therefore, it is difficult to achieve the purpose of fast and effective fixing of covered cables during field operations. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a wiring device for communication wires, aiming to solve the problem that the current method of connecting communication wires has the problem of being able to withstand small pulling force or having limitations on the use of tools, making it difficult to achieve the purpose of fast and effective fixing.

[0006] To achieve the above object, the utility model is implemented through the following technical solution: a wiring device for a communication wire, the wiring device for the communication wire comprising:

[0037] Please combine Figure 1-Figure 10 , which is a schematic diagram of the structure of a wiring device for a communication wire 6 provided in one embodiment of the utility model, the wiring device for the communication wire includes a wiring box body 3, a wiring assembly 4 arranged on the wiring box body 3, and an isolation assembly arranged between the wiring box body 3 and the wiring assembly 4, wherein:

[0038] In order to accommodate the communication wire 6, the junction box body 3 includes a cavity 37 and a receiving cavity 38 provided at both ends of the cavity 37. The housing of the receiving cavity 38 is provided with an inlet hole 33 and an outlet hole 34 for the communication wire 6 to pass through, and a plurality of terminal holes 35 for clamping the push button 41. The inlet hole 33 and the outlet hole 34 are connected to the receiving cavity 38, and the terminal hole 35 is connected to the cavity 37. In addition, a wire clamping hole 42 corresponding to the terminal hole 35 is also provided on the end surface of the junction box body 3 away from the inlet hole 33, and the wire clamping hole 42 is connected to the cavity 37.

[0039] In order to clamp the communication wire 6, an elastic sleeve 5 is installed on the wire entry hole 33, and a hole edge bevel 31 is provided on the outer edge of the wire entry hole 33, so that when the elastic sleeve 5 is installed, it can play a good guiding role to quickly achieve installation. The outer periphery of the elastic sleeve 5 is provided with an outer bevel 52 and an outer corner. When it is installed in the wire entry hole 33, the hole edge bevel 31 and the outer bevel 52 cooperate with each other to improve the convenience and operability of assembly. The outer bevel 52 and the outer corner are respectively clamped on both sides of the junction box body 3, so that the elastic sleeve 5 is clamped in the wire entry hole 33 for clamping the communication wire 6.

[0040] Furthermore, an inner port 53 and an outer port 54 are respectively provided at the front and rear ends of the elastic sleeve 5. The diameter of the inner port 53 is smaller than the diameter of the communication wire 6, and the diameter of the outer port 54 is larger than the outer diameter of the communication wire 6. A constricted bevel 51 is also provided at one end of the inner circumference of the elastic sleeve 5 near the inner port 53. During assembly, the communication wire 6 enters from the outer port 54 and then passes through the inner port 53. At this time, the inner port 53 is expanded by force, and the communication wire 6 can pass smoothly. When the communication wire 6 is pulled, the constricted bevel 51 generates a force in the direction of the outer port 54 by friction, driving the inner port 53 to squeeze in the direction of the outer port 54. The communication wire 6 will be subject to a large resistance. When the pulling force on the communication wire 6 is less than the resistance, the force-bearing area of ​​the communication wire 6 is the place where it is connected to the elastic sleeve 5, and the rear section of the communication wire 6 will not be subject to force.

[0041] In this embodiment, the communication wire 6 is formed by twisting two single-strand wires 62. After the communication wire 6 passes through the elastic sleeve 5, the communication wire 6 is knotted to form a knot 61. The outer diameter of the knot 61 is much larger than the inner diameter of the elastic sleeve 5. After the communication wire 6 is pulled by a large force, the knot 61 will serve as a force-bearing part. Similarly, the single-strand wire 62 is not subjected to force at the wire entry hole 33. After passing through the elastic sleeve 5, the communication wire 6 passes through the wire outlet hole 34 set on the junction box body 3 and is split into two separate single-strand wires 62. The outer edge of the wire outlet hole 34 is provided with an outer fillet 36 to prevent the single-strand wire 62 from being worn at the edge.

[0042] In order to handle the wire ends passing through the accommodating cavity 38, a wire clamping hole 42 corresponding to the terminal hole 35 is provided on the end face of the junction box body 3 away from the wire entry hole 33, and a wire groove 32 is also provided on this end face to expose the wire clamping hole 42. The wire clamping hole 42 is connected to the cavity 37 to clamp the end of the single-strand wire 62 in the cavity 37.

[0043] In order to clamp the end of the single-strand wire 62, the wiring assembly 4 includes a push button 41, a wiring rod 44 coaxially connected to the push button 41, and an insulating sleeve 43 sleeved on the wiring rod 44. In order to avoid contact between the wiring rod 44 and the wiring box body 3, an isolation assembly is also provided between the wiring rod 44 and the wiring box body 3. The isolation assembly includes a sealing member 7 sleeved on the outer periphery of the insulating sleeve 43, a pad 8 provided on the inner side of the wiring box body 3, and a gasket 9 provided on the pad 8. The sealing member 7 is provided on the end surface of the wiring post hole 35, and the elastic member 10 is provided between the gasket 9 and the fastener 101. When a pressing force is applied to the push button 41, the wiring rod 44 moves inward, and the elastic member 10 begins to compress, so that the wire end is inserted from the wire clamping hole 42 and is provided on the wiring rod 44. Then, the push button 41 is released, and due to the recovery effect of the elastic member 10, the wire end is clamped between the wiring rod 44 and the wiring box body 3.

[0044] The connection rod 44 first passes through the connection post hole 35 set on the connection box body 3, and then passes through the pad 8 set on the inner side of the connection box body 3. The pad 8 is padded with a washer 9 and an elastic member 10. The fastener 101 is tightened on the tail of the connection rod 44. At this time, the insulating sleeve 43 is completely in the connection post hole 35. After the fastener 101 is tightened, the elastic member 10 is completely flattened, thereby providing a certain pre-tightening force to prevent the fastener 101 from loosening. The sealing member 7 is sleeved on the insulating sleeve 43, and the sealing member 7 and the connection box body 3 are end-face sealed. The pad 8 and the insulating sleeve 43 are both made of non-metallic materials to prevent the connection rod 44 from directly contacting the connection post hole 35, thereby avoiding circuit short circuit.

[0045] The junction box body 3 is also equipped with a cover assembly, which includes a first cover 1 and a second cover 2 detachably connected to the first cover 1, the second cover 2 covers the accommodating cavity 38, and the first cover 1 is provided with a female buckle 11 for connecting the second cover 2. The second cover 2 is assembled on both sides of the first cover 1 and can be disassembled and assembled separately. The first cover 1 is provided with a female buckle 11 and a guide rail groove 12, and the second cover 2 is provided with an anti-slip groove 21, a directional arrow 22, a male buckle 23 and a guide rail edge 24. When installing the second cover 2, first insert the guide rail edge 24 into the guide rail groove 12, and push along the groove position so that the male buckle 23 is completely buckled with the female buckle 11, and the installation is completed. When disassembling the second cover 2, press the anti-slip groove 21 to make the male buckle 23 come out of the female buckle 11, and then push along the direction indicated by the directional arrow 22, so that the guide rail edge 24 is completely out of the guide rail groove 12, and the disassembly is completed.

[0046] In summary, according to a wiring device for a communication wire provided by the utility model, the communication wire is inserted into a wiring box body, and the inserted part is tied with a knot, and the knot is clamped inside the wiring box body, and the end of the communication wire is connected to the wiring rod, so as to avoid the end affecting the external operation, and to achieve rapid and effective fixation without the help of external tools. Specifically, after the communication wire is inserted into the accommodating cavity on both sides of the wiring box body, a knot is tied to be clamped inside the wiring box body to provide sufficient tensile strength. After applying a pressing force to the push button, the end of the communication wire is clamped on the wiring rod inside the wiring box body, and the push button is released. The restoring force of the elastic member pushes the push button out, thereby clamping the end of the communication wire between the wiring rod and the wiring box body. In addition, the isolation component prevents the wiring screw from directly contacting the wiring box body, thereby avoiding a short circuit in the circuit.
