[0034] like Figure 1 and Figure 2The cable connector shown includes a first connector 1 and a second connector 2. The right end of the first connector 1 and the left end of the second connector 2 are connected by a plug-in structure. A first cable channel extending through the first connector 1 in a left-right direction is provided inside the first connector 1, and a second cable channel extending through the second connector 2 in a left-right direction is provided inside the second connector 2. A first end cap 5 is threaded to the left end of the first connector 1. A first cable through hole is provided on the first end cap 5. A first ring 7 is provided at the left end of the first cable channel. The inner surface of the first ring 7 is a first conical surface with a diameter that gradually decreases from left to right. A first clamping member 6 is provided between the first end cap 5 and the first conical surface. The right side of the first clamping member 6 is provided with multiple... The first clamping arm 602, when tightened to the right, can compress the first clamping member 6 to the right, and guide the multiple first clamping arms 602 to retract through the first conical surface to clamp the cable. The right end of the second connector 2 is threadedly connected to a second end cap 8, which has a second cable through hole. The right end of the second cable channel has a second ring 10, the inner surface of which is a second conical surface with a diameter that gradually decreases from right to left. A second clamping member 9 is positioned between the second end cap 8 and the second conical surface. The left side of the second clamping member 9 has multiple second clamping arms 902. Tightening the second end cap 8 to the left can compress the second clamping member 9 to the left, and guide the multiple second clamping arms 902 to retract through the second conical surface to clamp the cable. By adopting the above technical solution, the cable can be clamped by setting the end cap, clamping member, and ring, keeping the two cable segments highly coaxial and reducing the damage to the cable joint caused by external forces such as bending.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, the first end cap 5 includes a first end cap body 501 and a first annular groove 502 disposed on the right side of the first end cap body 501. The left side of the first clamping member 6 is provided with a first annular base 601 that mates with the first annular groove 502. The second end cap 8 includes a second end cap body 801 and a second annular groove 802 disposed on the left side of the second end cap body 801. The right side of the second clamping member 9 is provided with a second annular base 901 that mates with the second annular groove 802. By providing the first annular groove 502 and the first annular base 601, the position of the first clamping member 6 can be maintained, which helps to ensure the clamping effect and reduces the installation difficulty. Similarly, by providing the second annular groove 802 and the second annular base 901, the position of the second clamping member 9 can be maintained, which helps to ensure the clamping effect and reduces the installation difficulty.

[0036] In some embodiments, in order to ensure the clamping effect, multiple first clamping arms 602 are evenly arranged in the circumferential direction of the first annular base 601, and multiple second clamping arms 902 are evenly arranged in the circumferential direction of the second annular base 901. Both the multiple first clamping arms 602 and the multiple second clamping arms 902 are made of rubber.

[0037] In some embodiments, such as Figure 1 and Figure 3 As shown, the plug-in structure includes a slot 101 located at the right end of the first connector 1 and a plug block 201 located at the left end of the second connector 2. A spring pin assembly 3 is provided on the plug block 201, and a limiting groove 102 is provided on the inner side wall of the slot 101. The spring pin assembly 3 cooperates with the limiting groove 102 to lock the relative positions of the first connector 1 and the second connector 2.

[0038] In some embodiments, such as Figure 1 and Figure 3 As shown, a receiving groove 202 is provided on the outer wall of the insert portion 201. The spring pin assembly 3 includes a first spring 301 and a limiting pin 302 both disposed in the receiving groove 202. The first spring 301 pushes the limiting pin 302 outward, and the pin head of the limiting pin 302 extends out of the receiving groove 202 and cooperates with the limiting groove 102. In a specific implementation, the end of the limiting pin 302 is provided as a ball head, and the root of the limiting pin 302 is fixedly connected to a first limiting plate 303 to prevent the limiting pin 302 from falling out of the receiving groove 202.

[0039] In some embodiments, such as Figure 1 and Figure 3 As shown, a pressing component 4 is provided on the right end of the first connector 1 to drive the spring pin assembly 3 out of the limiting groove 102. The pressing component 4 has an exposed operating part. By providing the pressing component 4 and the spring pin assembly 3, the two cooperate to achieve quick connection and disconnection between the first connector 1 and the second connector 2. As a preferred embodiment, in order to ensure the stability of the connection between the first connector 1 and the second connector 2, multiple spring pin assemblies 3 and multiple pressing components 4 are arranged in the circumferential direction of the cable connector. In specific implementation, two spring pin assemblies 3 and two pressing components 4 can be arranged in the circumferential direction of the cable connector.

[0040] In some embodiments, such as Figure 1 and Figure 3As shown, the right end of the first connector 1 is provided with a mating hole 103. The pressing assembly 4 includes a pressure rod 401 that mates with the mating hole 103 and a pressure plate 403 disposed in the limiting groove 102. One end of the pressure rod 401 extends into the limiting groove 102 and is fixedly connected to the pressure plate 403. The other end of the pressure rod 401 extends outward from the right end of the first connector 1 to form an operating part. In a specific implementation, the middle section of the mating hole 103 is a large-diameter section 104. A second limiting plate 404 and a second spring 402 that pushes the second limiting plate 404 outward are disposed in the large-diameter section 104. The middle part of the pressure rod 401 is fixedly connected to the second limiting plate 404. By pressing the pressure rod 401, the pressure plate 403 can be driven to squeeze the limiting pin 302, causing the end of the limiting pin 302 to leave the limiting groove 102. As a preferred example, the pressure plate 403 is an arc-shaped plate that can match the ball head of the limiting pin 302.

[0041] In some embodiments, such as Figure 1 As shown, a sealing ring 12 is provided between the first connector 1 and the second connector 2.

[0042] In some embodiments, such as Figure 1 and Figure 4 As shown, electromagnetic shielding layers 11 are provided on the inner walls of both the first and second cable channels. By providing electromagnetic shielding layers 11, electromagnetic interference at the cable joints can be reduced, ensuring the stability of communication signals.

[0043] like Figures 1 to 6 As shown, the present invention also proposes a cable connection structure, including a first cable 13, a second cable 14, a connecting socket 15, a connecting plug 16, and a cable connector as described in any one of the above. The end of the first cable 13 passes through a first cable through-hole and extends into a first cable channel. The connecting socket 15 is connected to the end of the first cable 13. The end of the second cable 14 passes through a second cable through-hole and extends into a second cable channel. The connecting plug 16 is connected to the end of the second cable 14. The connecting plug 16 and the connecting socket 15 are fixedly connected together by a snap-fit ​​structure to connect the first cable 13 and the second cable 14 together. A first clamping member 6 clamps the first cable 13, and a second clamping member 9 clamps the second cable 14.

[0044] In specific implementation, the connector 15 is provided with multiple connector holes 1501, each of which is provided with a first connector terminal that is electrically connected to the first cable 13. The connector plug 16 is provided with multiple second connector terminals 1601 that are electrically connected to the second cable 14. When the connector plug 16 is connected to the connector 15, the multiple second connector terminals 1601 extend into the multiple connector holes 1501 respectively and are connected to the multiple first connector terminals respectively, so as to realize the electrical connection between the first cable 13 and the second cable 14.

[0045] In some embodiments, the snap-fit ​​structure includes a slot 1502 disposed on the connector socket 15 and a locking block 1602 disposed on the connector plug 16. In specific implementations, to ensure a stable snap-fit, multiple slots 1502 are provided circumferentially on the connector socket 15, and multiple locking blocks 1602 are provided circumferentially on the connector plug. As a preferred example, the slots 1502 are configured as through holes, and the locking blocks 1602 are elastic locking blocks 1602, which can be pressed to engage the snap-fit ​​mechanism.

[0046] The installation process of the cable connection structure is as follows: First connector 1 and second connector 2 are respectively fitted onto the ends of first cable 13 and second cable 14. Then, connector socket 15 is connected to the end of first cable 13, connector plug 16 is connected to the end of second cable 14, connector socket 15 and connector plug 16 are then inserted together and fixed by snap-fit ​​structure. Then, first connector 1 and second connector 2 are inserted together, and the two first end caps 5 and second end caps 8 are tightened. First clamping member 6 is used to press and fix first cable 13, and second clamping member 9 is used to press and fix second cable 14, so that the cable segments inside the first cable channel and the second cable channel are kept highly coaxial, reducing the damage to the cable joint caused by external forces such as bending. Electromagnetic shielding layer 11 blocks external electromagnetic interference to the cable joint and maintains the stability of communication signal.

[0047] The disassembly process of the cable connection structure is as follows: Loosen the first end cap 5 and the second end cap 8 to disengage the first clamping member 6 from the first cable 13 and the second clamping member 9 from the second cable 14. Then press the pressing assembly 4, the pressure rod 401 and the pressure plate 403 to press down the limiting pin 302 until the limiting pin 302 disengages from the limiting groove 102. Then pull out the first connector 1 and the second connector 2 to separate them. Disassembly and assembly are convenient. If you want to disconnect the connection between the first cable 13 and the second cable 14, simply press down the locking block 1602 to disengage it from the locking groove 1502, and then you can pull out the connecting socket 15 and the connecting plug 16. Using the above cable connection structure, the quick connection and disconnection of the first cable 13 and the second cable 14 can be easily achieved.
