[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0035] The cable assembly of the embodiment of the utility model includes a plurality of cables 1 and at least one connector set 2 .

[0036] At least one of the plurality of cables 1 is provided with an elastically deformable elastic section 13. For example, Figure 1 As shown, there may be two cables 1 , which are a first cable 11 and a second cable 12 . Each of the first cable 11 and the second cable 12 may be provided with an elastic section 13 .

[0037] The elastic segment 13 itself has a certain elastic deformation performance, that is, the elastic segment 13 can be elastically deformed along the extension direction of the cable 1, so that the cable 1 can have a certain elasticity and reduce the impact of external force on the cable 1, further reducing the possibility of the cable 1 breaking.

[0038] In some other embodiments, the cables 1 may be provided with three, four, five, etc. In other embodiments, only a part of the cables 1 may be provided with elastic segments 13, for example, the first cable 11 may be provided with elastic segments 13, and the second cable 12 may be straight. In other embodiments, each cable 1 may be provided with more than two elastic segments 13.

[0039] The connector group 2 includes a first connector 21 and a second connector 22. The first connector 21 is arranged at one of the two adjacent cables 1, and the second connector 22 is arranged at the other of the two adjacent cables 1. The first connector 21 and the second connector 22 are detachably connected. The connection force between the first connector 21 and the second connector 22 is less than a set threshold so that the first connector 21 and the second connector 22 can be separated when the cable assembly is pulled.

[0040] For example, the number of connector groups 2 is one less than the number of cables 1, and any two adjacent cables 1 can be electrically connected through one connector group 2. For example, there may be only two cables 1, and the two cables 1 are the first cable 11 and the second cable 12. In this case, there may be only one connector group 2, and the connector group 2 may be only provided between the first cable 11 and the second cable 12.

[0041] The connector group 2 includes a first connector 21 fixedly mounted at the end of the first cable 11 and a second connector 22 fixedly mounted at the end of the second cable 12. The first connector 21 and the second connector 22 can be connected by plugging, snapping, etc., and the connection force between the first connector 21 and the second connector 22 must be less than a set threshold, which is a certain tension value less than the maximum tension that the cable 1 can withstand. It should be noted that the connection force can be a fixing force such as a friction force and a snapping force for connecting and fixing the first connector 21 and the second connector 22.

[0042] Therefore, when the cable assembly is subjected to tension, the first connector 21 and the second connector 22 will separate before the cable 1 is broken, thereby achieving the self-disconnection of the cable assembly when subjected to a large tension, avoiding the cable 1 from being broken, protecting the cable 1 itself, and avoiding the problem of head and neck injuries caused by pulling on helmets, etc., thus protecting personnel and improving safety of use.

[0043] In some embodiments, the first connector 21 and the second connector 22 are connected by magnetic attraction, and the connection force is the magnetic attraction force between the first connector 21 and the second connector 22. For example, the first connector 21 and the second connector 22 may be provided with magnetic parts such as permanent magnets, and during assembly, the first connector 21 and the second connector 22 may be connected by the magnetic attraction of the magnetic parts, thereby facilitating assembly and meeting the need for automatic disconnection when pulled.

[0044] In some embodiments, the first connector 21 is provided with a plurality of first magnets 211 , and the second connector 22 is provided with a plurality of second magnets 221 . The plurality of first magnets 211 and the plurality of second magnets 221 are magnetically connected in a one-to-one correspondence.

[0045] For example, Figures 2 to 4 As shown, the first magnet 211 and the second magnet 221 can both be permanent magnets, each first magnet 211 and each second magnet 221 can be generally cylindrical, a plurality of first magnets 211 can be arranged at equal intervals along the circumference of the first connector 21, and a plurality of second magnets 221 can be arranged at equal intervals along the circumference of the second connector 22.

[0046] When assembling the first connector 21 and the second connector 22 , each first magnet 211 can be respectively opposite to and magnetically connected with the corresponding second magnet 221 , thereby facilitating the assembly of the first connector 21 and the second connector 22 .

[0047] In some embodiments, at least a portion of the first magnet 211 protrudes from the surface of the first connector 21 and forms a protrusion 214, and at least a portion of the second magnet 221 sinks into the second connector 22 to construct a plurality of sockets 224 on the second connector 22, and the plurality of protrusions 214 are plugged into the plurality of sockets 224 one by one.

[0048] For example, Figure 2 As shown, the first magnets 211 generally extend in the up-down direction, and a portion of each first magnet 211 may protrude from the upper surface of the first connector 21, and the protruding portion is the protrusion 214. Figure 3As shown, each second magnet 221 can be embedded in the second connector 22 , and the lower end surface of each second magnet 221 is staggered with the corresponding surface of the second connector 22 in the upper and lower directions, and the space formed by the staggered arrangement is the insertion hole 224 .

[0049] When assembling the first connector 21 and the second connector 22, the protrusions 214 can be respectively plugged into the corresponding sockets 224. Thus, on the one hand, the accuracy and stability of the docking of the first connector 21 and the second connector 22 can be ensured, and on the other hand, the structural strength in the lateral direction can be enhanced, thereby avoiding the first connector 21 and the second connector 22 from rotating relative to each other or the situation where the force that can be borne in the lateral direction is small, and fully ensuring the stability of the structure.

[0050] In some embodiments, the number of the plurality of first magnets 211 on the first connector 21 is adjustable. For example, the first magnets 211 can be installed and fixed by threaded assembly, plug-in, etc. When in use, the number of the first magnets 211 and the distribution positions of the plurality of first magnets 211 can be adjusted according to actual needs, so that the magnitude of the magnetic attraction force and the magnetic attraction point between the first connector 21 and the second connector 22 can be adjusted.

[0051] Similarly, the number of the multiple second magnets 221 on the second connector 22 is adjustable, and the second magnets 221 can also be installed and fixed by threaded assembly, plug-in, etc. When in use, the number of the second magnets 221 and the distribution positions of the multiple second magnets 221 can be adjusted according to actual needs, thereby also achieving the adjustment of the size of the magnetic attraction force and the magnetic attraction point between the first connector 21 and the second connector 22.

[0052] In some embodiments, Figure 2 As shown, the first connector 21 includes a first conductor 212, which may be a copper core, and the second connector 22 includes a second conductor 222, which may also be a copper core. When the first connector 21 and the second connector 22 are assembled, the first conductor 212 is electrically connected to the second conductor 222, thereby meeting the use requirements of power supply, communication, etc.

[0053] The plurality of first magnets 211 are disposed on the circumferential side of the first conductor 212 and are arranged at intervals along the circumferential direction of the first conductor 212 . The plurality of second magnets 221 are disposed on the circumferential side of the second conductor 222 and are arranged at intervals along the circumferential direction of the second conductor 222 .

[0054] Specifically, Figure 2 As shown, the first conductor 212 may be arranged concentrically with the first connector 21, and a plurality of first magnets 211 may be arranged on the outer circumference of the first conductor 212 and arranged at equal intervals along the circumference of the first conductor 212. Figure 3 and Figure 4 As shown, the second conductor 222 can be arranged concentrically with the second connector 22, and the plurality of second magnets 221 can be arranged on the outer peripheral side of the second conductor 222 and arranged at equal intervals along the circumference of the second conductor 222. Thus, the consistency of the circumferential connection function of the first connector 21 and the second connector 22 and the balance of the magnetic attraction function are fully guaranteed.

[0055] In some embodiments, the first connector 21 includes a plug-in portion 213, and the second connector 22 includes a slot 223, and the plug-in portion 213 is plugged into the slot 223. Figure 2 As shown, the plug-in portion 213 may be substantially in the shape of a circular column, the first conductor 212 may be disposed in the plug-in portion 213, and each first magnet 211 may be disposed in the plug-in portion 213. Figure 3 As shown, the second connector 22 as a whole can also be in the shape of a circular column, and the slot 223 is the internal space of the second connector 22. When assembling the first connector 21 and the second connector 22, the plug-in portion 213 can be directly plugged into the slot 223, thereby enhancing the structural stability and firmness of the assembly of the first connector 21 and the second connector 22.

[0056] The first conductor 212 and the first magnet 211 are both disposed in the plug-in portion 213 and exposed from the end surface of the plug-in portion 213 toward the slot 223, and the second conductor 222 and the second magnet 221 are both disposed on the bottom wall of the slot 223. Figure 2 As shown, the plug-in portion 213 can be generally annular and cylindrical, and the upper annular end surface of the plug-in portion 213 is used to face the second connector 22, and a portion of the first conductor 212 and each first magnet 211 can be exposed from the upper annular end surface of the plug-in portion 213. Figure 3 As shown, the second conductor 222 and the second magnet 221 can be disposed in the second connector 22, and the second conductor 222 and each second magnet 221 can be exposed from the bottom wall of the slot 223 (the slot wall arranged opposite to the slot opening of the slot 223).

[0057] Thus, when the plug-in portion 213 is plugged into the slot 223 , the first conductor 212 and the second conductor 222 are arranged relative to each other and can be docked, and each first magnet 211 and each second magnet 221 are arranged relative to each other and can be docked.

[0058] In some embodiments, the first conductor 212 and the second conductor 222 are plugged together. For example, a groove may be provided on the first conductor 212, and when the first connector 21 and the second connector 22 are assembled, a portion of the second conductor 222 may be plugged together in the groove of the first conductor 212, thereby ensuring the stability of the electrical connection.

[0059] In some embodiments, the first conductor 212 and the second conductor 222 are both metal conductors, which can be copper conductors, aluminum conductors, etc., thereby ensuring the stability of the electrical connection.

[0060] In some embodiments, the cable assembly includes a seal 3 , and at least one of the first connector 21 and the second connector 22 is provided with the seal 3 , and the seal 3 is used to achieve a waterproof seal between the first connector 21 and the second connector 22 .

[0061] For example, the material of the sealing member 3 may be rubber or silicone. Figure 2 As shown, the seal 3 can be only provided on the first connector 21 , and the seal 3 as a whole can be annular, that is, the seal 3 extends along the circumference of the first connector 21 to form a circle, and the seal 3 can specifically surround the outer peripheral side of the plug-in portion 213 .

[0062] When the plug-in portion 213 of the first connector 21 is plugged into and assembled in the slot 223 of the second connector 22, the seal 3 can come into contact with the end face of the peripheral side of the notch of the slot 223 of the second connector 22, thereby ensuring a waterproof seal for the first connector 21 and the second connector 22, and preventing liquid and other impurities from entering the first conductor 212, the second conductor 222, the first magnet 211, and the second magnet 221 through the gap between the plug-in portion 213 and the slot 223.

[0063] In some embodiments, the elastic section 13 extends spirally along the extension direction of the cable 1. Figure 1 As shown, the elastic section 13 as a whole can be a spiral structure, thereby reducing the requirements on the material of the cable 1, that is, by changing the shape of the cable 1, a part of the cable 1 can have the ability of elastic deformation, thereby meeting the needs of use.
