Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to an insulated motor lead cable. Background Technology

[0002] An insulated motor is a motor in which non-conductive materials are used to isolate the various parts of the motor. This is to prevent the motor from being directly grounded or coming into contact with impurities, which would cause current to flow out, thus ensuring human safety and the normal operation of the equipment. When using it, a type of flexible lead cable is used. The lead cable of the insulated motor is an important part of the motor. It is responsible for connecting the various parts of the motor and ensuring the safety and stability of current transmission.

[0003] A search revealed an existing patent (publication number: CN203787194U) that discloses a high-voltage resistant reinforced insulation motor lead cable. This cable employs a cross-woven fiber rope mesh layer, which not only strengthens the cable's insulation but also allows it to withstand greater tensile force, extending its service life. The use of a composite semiconductor shielding wrapping layer reduces the wrapping process, decreases the gap between the conductor and insulation layer, ensures an effective and uniform electric field, and simultaneously reduces production steps, improving production efficiency.

[0004] However, in the above solution, the cable will sometimes be used on the ground, so it is necessary to strengthen the cable's pressure resistance to make it more cushioned and prevent it from being damaged by being stepped on. Utility Model Content

[0005] Therefore, this utility model provides an insulated motor lead cable to solve the above-mentioned problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A first tensile core is provided between the six sets of cable conductors near the supporting inner core, and a second tensile core is provided between the six sets of cable conductors near the buffer flame-retardant layer.

[0008] Furthermore, a spacer ring is provided on the outer side of the wear-resistant protective jacket, and the spacer rings are evenly distributed on the surface of the wear-resistant protective jacket.

[0009] Furthermore, the buffer flame retardant layer is provided with an outer mesh layer and an inner mesh layer on both sides, and the outer mesh layer and the inner mesh layer are made of TPE thermoplastic elastomer material.

[0010] Furthermore, the buffer flame retardant layer is a flame retardant powder, and a grid structure is uniformly arranged between the outer grid layer and the inner grid layer on both sides of the buffer flame retardant layer, with the buffer flame retardant layer filling the space between the outer grid layer and the inner grid layer.

[0011] Furthermore, the supporting core is also made of TPE thermoplastic elastomer material, and the interior of the supporting core is provided with six sets of buffer cavities, and the distribution of the six sets of buffer cavities corresponds to the position distribution of the cable conductor.

[0012] Furthermore, the first tensile core is provided in six groups, and the six groups of first tensile cores are distributed between the cable conductors, and the gap between the cable conductors and the first tensile cores is filled with gap filler.

[0013] Furthermore, the second tensile core is also provided in six groups, and the six groups of second tensile cores are distributed between the cable conductors, with gap filler filling the space between the second tensile core and the cable conductor.

[0014] Furthermore, the second tensile core and the first tensile core are composed of a mixture of steel wire strands and nylon wires.

[0015] This utility model has the following advantages:

[0016] 1. In this utility model, the wear resistance of the cable is increased by setting an external wear-resistant protective jacket. The mesh structure between the outer and inner mesh layers increases the elasticity between the outer and inner mesh layers, playing a buffering role. The buffer flame-retardant layer can play a flame-retardant role with flame retardant.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, an insulated motor lead cable according to the first aspect embodiment of this utility model includes an abrasion-resistant protective jacket 1, a spacing ring 101, a cable conductor 2, a buffer flame-retardant layer 3, an outer mesh layer 301, an inner mesh layer 302, a pressure-resistant fiber layer 4, a supporting inner core 5, a buffer inner cavity 501, a first tensile core 6, and a second tensile core 7. The abrasion-resistant protective jacket 1 has six sets of cable conductors 2 inside, and a spacing ring 101 is provided on the outer side of the abrasion-resistant protective jacket 1. The spacing rings 101 are evenly distributed on the surface of the abrasion-resistant protective jacket 1. The spacing rings 101 can reduce the friction on the surface of the abrasion-resistant protective jacket 1 and also facilitate the observation of the length dimension of the abrasion-resistant protective jacket 1.

[0026] The inner side of the cable conductor 2 is provided with a support core 5, which is also made of TPE thermoplastic elastomer material. The support core 5 has six sets of buffer cavities 501 inside, and the distribution of the six sets of buffer cavities 501 corresponds to the position distribution of the cable conductor 2. When the cable conductor 2 is squeezed, the buffer cavity 501 of the support core 5 can deform, so that the cable conductor 2 can be squeezed to one side of the buffer cavity 501. In this way, the buffer cavity 501 can buffer the cable conductor 2.

[0027] The outer side of the six sets of cable conductors 2 is wrapped with a buffer flame-retardant layer 3. The buffer flame-retardant layer 3 has an outer mesh layer 301 and an inner mesh layer 302 on both sides. The outer mesh layer 301 and the inner mesh layer 302 are made of TPE thermoplastic elastomer material. The outer mesh layer 301 and the inner mesh layer 302 can increase the compressive strength of the device.

[0028] The buffer flame retardant layer 3 is a flame retardant powder, and a grid structure is uniformly arranged between the outer grid layer 301 and the inner grid layer 302 on both sides of the buffer flame retardant layer 3. The buffer flame retardant layer 3 fills between the outer grid layer 301 and the inner grid layer 302. The uniformly arranged grid structure between the outer grid layer 301 and the inner grid layer 302 can stabilize the flame retardant powder and make the distribution of the flame retardant powder more uniform. The uniformly arranged grid structure between the outer grid layer 301 and the inner grid layer 302 can increase the elasticity of the outer grid layer 301 and the inner grid layer 302 and improve the compressive strength of the device.

[0029] A first tensile core 6 is provided on the side of the six sets of cable conductors 2 near the supporting inner core 5. There are six sets of first tensile cores 6, and the six sets of first tensile cores 6 are distributed between the cable conductors 2. The gap between the cable conductors 2 and the first tensile cores 6 is filled with filler. The first tensile cores 6 can increase the tensile strength of the device.

[0030] A second tensile core 7 is provided between the six sets of cable conductors 2 on the side near the buffer flame-retardant layer 3. There are also six sets of the second tensile core 7, and the six sets of the second tensile core 7 are distributed between the cable conductors 2. The gap between the second tensile core 7 and the cable conductor 2 is filled with filler. The second tensile core 7 is distributed between the cable conductors 2 in this way, which can more evenly assist the tensile strength of the cable conductor 2, making the tensile strength of the device more uniform and stable.

[0031] The second tensile core 7 and the first tensile core 6 are composed of a mixture of steel wire strands and nylon threads. This increases the tensile strength of the device, while the nylon threads also increase its toughness and weight.

[0032] The technical effects achieved by the above embodiments are as follows: the wear resistance of the cable is increased by setting an external wear-resistant protective jacket 1, and the internal sandwich layer of buffer flame retardant layer 3, outer mesh layer 301 and inner mesh layer 302 can increase the compressive strength of the cable. The mesh structure between the outer mesh layer 301 and inner mesh layer 302 increases the elasticity between the outer mesh layer 301 and inner mesh layer 302, playing a buffering role. The buffer flame retardant layer 3 between the outer mesh layer 301 and inner mesh layer 302 can play a flame retardant role through flame retardant. The internal support core 5 can buffer the cable conductor 2 by buffering the deformation of the inner cavity 501 when the cable conductor 2 is squeezed, making the cable more compressive strength. The first tensile core 6 can increase the tensile strength of the device, and the second tensile core 7 distributed between the cable conductors 2 can more evenly assist the tensile strength of the cable conductor 2, making the tensile strength of the device more uniform and stable.
