[0003] With the widespread application of cable assemblies in the field of communications, the requirements for the stability of the electrical performance, service life and environmental resistance of cable assemblies are becoming increasingly higher. During the use of currently commonly used cable assemblies, when the internal current carrying capacity of the cable is too large, the cable will cause heating, and the insulation layer in contact with it will transfer the heat. When the heat of the insulation layer accumulates to its own melting point, it will spontaneously combust, further igniting adjacent cables, which can easily cause a fire. Summary of the invention

[0020] The embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The following is an embodiment of the present invention, please refer to Figures 1 to 3 .

[0022] A fireproof and waterproof cable assembly, the cable assembly comprising a cable connector 4, and a cable body 1 detachably connected to the cable connector 4, both ends of the cable body 1 being connected to the cable connector 4; the cable body 1 comprising an insulating layer 11, a central cable 3 wrapped by the insulating layer 11, and a plurality of peripheral cables 2 surrounding the central cable 3; the central cable 3 and the plurality of peripheral cables 2 both comprising a central conductor 21, and also comprising an insulating and waterproof layer 22 wrapping the central conductor 21; a heat sink is provided on the insulating and waterproof layer 22, the heat sink comprising an elastic spacer 8 in a spiral ascending shape, the spacer 8 being provided with a plurality of support members 71 at intervals along the spiral ascending direction, the central cable 3 and the plurality of peripheral cables 2 passing through the plurality of support members 71.

[0023] It should be noted that the heat sink should be elastic. When the central cable 3 or the peripheral cable 2 is passed through the support member 71 on the heat sink, the heat sink is compressed to the same position using its own elasticity, and then the central cable 3 and the peripheral cable 2 are respectively inserted into the support member 71. After that, the heat sink is unfolded to make it out of the compressed state for easy processing. A central cable 3 or a peripheral cable 2 can be passed through one, two or three support members 71, but a support member 71 can only pass one cable. As for how many support members 71 a cable is allowed to pass through, technicians in this field can set it according to needs, and no limitation is made here.

[0024] Specifically, when the central cable 3 and the peripheral cable 2 need to pass through the support member 71 , the isolation member 8 is in a compressed state to facilitate the central cable 3 and the peripheral cable 2 to pass through the support member 71 .

[0025] Specifically, the support member 71 is in a circular ring shape and the diameter of the support member 71 is greater than the diameters of the central cable 3 and the peripheral cable 2 .

[0026] Specifically, a plurality of vertical stripes are fixed at intervals on the surface of the inner circle of the support member 71 , so as to increase the heat dissipation area of ​​the central cable 3 and the peripheral cable 2 .

[0027] It can be understood that a number of vertical stripes are fixed on the surface of the inner circle of the support member 71, so that the several stripes are in contact with the cables passing through the support member 71, thereby increasing the heat dissipation area of ​​the cables passing through the support member 71; at the same time, the vertical stripes can also play a preliminary fixing role for the passing cables, and the gaps between the vertical stripes play a buffering role for the cables; and other structures for increasing the heat dissipation area can also be fixed on the support member 71, such as fixing a number of protrusions on the outer surface of the support member 71.

[0028] Specifically, an elastic buffer 5 is provided at a position of the cable connector 4 near where the cable connector 4 is fixed to the cable body 1 . The buffer 5 is located at one end of the cable connector 4 close to the cable body 1 , and the buffer 5 wraps the cable body 1 .

[0029] It is understandable that since the cable will rotate, the contact position between the cable and the cable connector 4 is prone to breakage. An elastic buffer 5 is provided at the cable connector 4 near the position where the cable connector 4 is fixed to the cable body 1, which can play a buffering role and make the contact position between the cable and the cable connector 4 less likely to break.

[0030] Preferably, the buffer member 5 is detachably connected to the cable connector 4 and the cable body 1 , and an anti-slip member 6 is provided on the surface of the buffer member 5 , and the anti-slip member 6 is provided with protrusions at intervals.

[0031] It can be understood that the anti-slip member 6 has a plurality of protrusions arranged at intervals, which are used to increase the heat dissipation area and also increase the friction force, making it easier to disassemble the buffer member.

[0032] The anti-slip member 6 in this embodiment is made of rubber.

[0033] Specifically, the cross section of the protrusion is polygonal, for example, the cross section of the protrusion may be pentagonal or hexagonal.

[0034] Specifically, the gaps between the spacer 8 and the central cable 3 and the plurality of peripheral cables 2 are filled with carbon fiber layers.

[0035] In this embodiment, since the central cable 3 and the peripheral cables 2 all include a central conductor 21 and an insulating waterproof layer 22 wrapping the central conductor 21, the central cable 3 and the peripheral cables 2 have a waterproof effect; a heat sink is further provided on the insulating waterproof layer 22, and the heat sink includes an elastic and spirally ascending spacer 8, and the spacer 8 is provided with a plurality of support members 71 at intervals along the spiral ascending direction. The central cable 3 and the peripheral cables 2 pass through the plurality of support members 71, so that the peripheral cables 2 and the central cable 3 are separated by the spacer 8, thereby increasing the heat dissipation area of ​​the central cable 3 and the peripheral cables 2. The central cable 3 and the peripheral cables 2 can obtain a larger area of ​​heat dissipation, so that the cables are not easily self-ignited due to overheating, thereby achieving a fire prevention effect. When the central cable 3 or the peripheral cables spontaneously ignite, due to the isolation effect of the support member 71, the adjacent cables will not be ignited, thereby further enhancing the fire prevention effect of the cables, thereby solving the technical problem that when the heat of the insulating layer 11 accumulates to its own melting point, spontaneous combustion will occur, and further ignition of adjacent cables will occur. The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
