Description

Technical Field

[0001] The present invention belongs to the technical field of communication cables or conductors with double-strand twisting, and particularly relates to a twisted-pair cable. Background Art

[0002] A twisted-pair cable is a transmission medium formed by encapsulating one or more pairs of twisted pairs in an insulating jacket. It is the most commonly used wiring material in current local area networks and is often used for physical line connections between network terminals in broadband networks and local area networks, such as devices like PCs, servers, switches, routers, etc. To reduce the degree of signal interference, each pair of twisted pairs in the cable is generally formed by twisting two insulated copper wires around each other, and thus the twisted pair gets its name.

[0003] Since the twisted pair is formed by twisting two wire cores inside, after preparation, there will be gaps outside the wire cores. During use, after the twisted pair is connected, it is usually only wrapped and fixed with insulating tape. Therefore, the fixing strength is insufficient, which will allow substances such as dust and moisture to enter the inside of the twisted pair. Moreover, when using insulating tape for fixing, the connection strength is insufficient and it is prone to breakage. Summary of the Invention

[0004] The present invention aims to provide a twisted-pair cable to solve the problems that there are gaps after the wire cores of the existing twisted pairs are twisted, and when fixing, only tape is used for fixing, which easily allows dust and moisture to enter the inside of the cable and affects the use of the cable.

[0005] To achieve the above object, the present invention adopts the following technical solution: A twisted-pair cable includes two wire cores twisted into a cable. A protective layer is wrapped outside the wire cores, and an elastomer is provided between the wire cores and the protective layer. At both ends of the protective layer, a first connecting member and a second connecting member are respectively fixed. Both the first connecting member and the second connecting member include a connecting pipe fixed at the end of the protective layer and a pipe sleeve threadedly connected to the connecting pipe. The pipe sleeve includes a rotating ring and a connecting ring rotatably connected to the rotating ring. The rotating ring is threadedly connected to the connecting pipe. On the inner wall of the connecting ring of the first connecting member, a first connecting seat is provided. At one end of the first connecting seat close to the connecting pipe, two first installation grooves for placing the wire cores are provided, and guide blocks are provided in the first installation grooves.

[0006] On the inner wall of the connecting ring of the second connecting member, a second connecting seat is provided. At one end of the second connecting seat close to the connecting pipe, two second installation grooves for placing the wire cores are provided, and conductive blocks are provided in the second installation grooves. The conductive blocks can be inserted into the first installation grooves. A fixing ring rotatably connected to the free end of the connecting ring of the first connecting member and threadedly connectable to the connecting ring of the second connecting member is also provided.

[0007] In the above technical solution, through the settings of the first connecting piece and the second connecting piece, the fixation of two cables can be completed, and the influence of the external environment on the cables can be reduced. Moreover, through the fixation of the first connecting piece and the second connecting piece, it is not necessary to use tape for fixation. Tape is disposable and not environmentally friendly, while the first connecting piece and the second connecting piece can be reused multiple times; and the connection completed by the first connecting piece and the second connecting piece can reduce the probability of detachment.

[0008] In another preferred embodiment of the present invention, an annular groove is provided on the outer ring of the protective layer, a sealed airbag is provided in the annular groove, and bumps for squeezing the sealed airbag are provided on the inner walls of the connecting ring and the second connecting ring.

[0010] In another preferred embodiment of the present invention, a limiting block that can abut against the connecting pipe is provided on the inner wall of the connecting ring near one end of the rotating ring.

[0011] In another preferred embodiment of the present invention, it further includes two wedge-shaped rods that respectively penetrate through the first connecting seat and are slidably connected to the first connecting seat, and further includes two driving rods that penetrate through the limiting block and are slidably connected to the limiting block. The driving rod is perpendicular to the wedge-shaped rod.

[0012] In another preferred embodiment of the present invention, a circular disc is provided on the outside of the connecting ring of the first connecting piece. A transverse groove is provided between the circular disc and the rotating ring, and a slider is slidably connected in the transverse groove; the fixed ring includes a first part fixed to the slider and a second part threadedly connected to the connecting ring. An annular groove is provided on one side of the first part close to the second part. The second part is rotatably connected to the annular groove, and the first part and the second part can slide relative to each other.

[0013] In another preferred embodiment of the present invention, a sealed airbag is provided at the joint where the connecting rings of the first connecting piece and the second connecting piece are in contact.

[0014] In another preferred embodiment of the present invention, a flow channel communicating with the sealed airbag is provided in the connecting ring of the second connecting piece, a slide plate is slidably connected in the flow channel, and a push rod is fixed on the slide plate.

[0022] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the communication inside two elements. It can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] The present invention provides a twisted pair cable. As Figure 1 shown, in a preferred embodiment of the present invention, it includes two wire cores 1 stranded into a cable. An elastomer 2 is provided between the wire cores 1 stranded into a cable and a protective layer 3 is wrapped outside the wire cores 1 stranded into a cable. A first connecting member and a second connecting member are respectively fixed at both ends of the protective layer 3. The structures of the first connecting member and the second connecting member are basically the same. Taking the first connecting member as the main description, the differences between the first connecting member and the second connecting member will be described separately.

[0024] The first connecting piece includes a connecting pipe 4 fixed to the right end of the protective layer 3 and a pipe sleeve threadedly connected to the connecting pipe 4. The pipe sleeve includes a rotating ring 5 and a connecting ring 6 rotatably connected to the rotating ring 5. The rotating ring 5 is threadedly connected to the connecting pipe 4. A limiting block 7 is provided at the left end of the connecting ring 6. The limiting block 7 can abut against the connecting pipe 4 to determine the installation positions of the first connecting piece and the second connecting piece.

[0025] On the inner wall of the connecting ring 6 of the first connecting piece, there is a first connecting seat 8. At the left end of the first connecting seat 8, there are two first installation grooves 10 for placing two wire cores 1. A guiding block 11 is arranged in the first installation groove 10. On the inner wall of the connecting ring 6 of the second connecting piece, there is a second connecting seat 9. At the right end of the second connecting seat 9, there are two installation grooves 10 for placing the wire core 1. A conductive block 12 is arranged in the second installation groove 10. During use, the conductive block 12 is inserted into the first installation groove 10 of the first connecting seat 8 so that the conductive block 12 is in contact with the guiding block 11, completing the connection of the two cables.

[0026] There are also two wedge-shaped rods 13 respectively passing through and slidably connected to the first connecting seat 8, and two driving rods 14 passing through and slidably connected to the limiting block 7. The driving rods 14 are perpendicular to the wedge-shaped rods 13. Therefore, when the connecting pipe 4 is connected to the pipe sleeve, during the process when the limiting block 7 abuts against the connecting pipe 4, the driving rods 14 will be driven to move, thereby squeezing the wedge-shaped rods 13 and causing the wedge-shaped rods 13 to slide into the first installation groove 10, realizing the fixation of the wire core 1 in the first installation groove 10. The second connecting piece is also provided with the same structure and is used in the same way.

[0027] An annular groove is provided on the outer circle at the right end of the protective layer 3, and a sealing airbag 15 is arranged in the annular groove; on the inner wall of the connecting ring 6, there is a convex block 16 that can squeeze the sealing airbag 15. The convex block 16 is hemispherical, so that the sealing airbag 15 can be tightly abutted against the connecting ring 6 and the first connecting seat 8 to achieve sealing.

[0028] Combined Figure 2 As shown, a fixing ring that can be threadedly connected to the connecting ring 6 of the second connecting piece is also rotatably connected to the right end of the connecting ring 6 of the first connecting piece. A circular disc 17 is arranged on the outside of the right end of the first connecting piece. A transverse groove 18 is provided between the circular disc 17 and the rotating ring 5, and a slider 19 is slidably connected in the transverse groove 18. The fixing ring includes a first part 20 on the left side and a second part 21 on the right side. The inner side of the first part 20 is fixed to the slider 19, and the second part 21 is threadedly connected to the connecting rings 6 of both the first connecting piece and the second connecting piece. An annular groove is provided at the right end of the first part 20, and a sliding block is provided at the left end of the second part 21. The sliding block can slide along the annular groove, so that sliding can occur when the second part 21 rotates.

[0029] At the place where the connecting rings 6 of the first connecting piece and the second connecting piece are in contact, a closed airbag 22 is provided. At the left end of the connecting ring 6 of the second connecting piece, a flow channel 23 communicating with the closed airbag 22 is provided. A slide plate 24 is slidably connected in the flow channel 23, and a push rod 25 is fixed to the left end of the slide plate 24. When the circular plate 17 on the first connecting piece abuts against the second connecting piece, it will drive the push rod 25 to move, so it will drive the slide plate 24 to move, thereby squeezing the gas in the flow channel 23 into the closed airbag 22, causing the closed airbag 22 to expand and sealing the gap between the first connecting piece and the second connecting piece, improving the sealing effect.

[0030] The specific usage process is as follows:

[0031] Fix the two ends of the cable to the first connecting piece and the second connecting piece respectively. Insert the wire cores 1 into the two first installation grooves 10 and the second installation grooves 10 respectively, and then thread the rotating ring 5 onto the connecting pipe 4 to fix the first connecting piece and the second connecting piece to the cable. During this process, the limiting block 7 on the connecting ring 6 will abut against the end of the connecting pipe 4, so it will drive the driving rod 14 to move and gradually drive the wedge-shaped rod 13, so that when the wedge-shaped rod 13 slides into the first installation groove 10 and the second installation groove 10, the wire core 1 is fixed in the first installation groove 10 and the second installation groove 10.

[0032] When the cable needs to be used, when connecting the cable, fix the first connecting piece and the second connecting piece of the two cables. Insert the connecting ring 6 of the first connecting piece into the connecting ring 6 of the second connecting piece, and make the left end of the second connecting piece abut against the circular plate 17; at this time, the push rod 25 will drive the slide plate 24 to slide, thereby introducing the gas in the flow channel 23 into the closed airbag 22, causing the closed airbag 22 to expand and realizing the sealing of the first connecting piece and the second connecting piece.

[0033] Then rotate the second part 21 so that the second part 21 is threadedly connected to the connecting ring 6 on the second connecting ring 6, and the second part 21 will move when rotating, so the fixation of the first connecting piece and the second connecting piece can be realized.

[0034] In summary, in the present invention, the first connecting piece and the second connecting piece can be used to fix two cables, and after fixation, the sealing airbag 15 and the closed airbag 22 can be used to realize sealing, thereby reducing the probability of moisture and external dust entering the cable interior and reducing the impact on the cable during use. Moreover, the first connecting piece and the second connecting piece are detachable, so they are convenient for repeated use.
