Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, and in particular to an external high-temperature resistant structure for connecting cables. Background Art
[0002] Conventional cables are flat or flat in structure. When they come into contact with high-temperature objects, such as the heating parts of equipment, their temperature will rise. The current high-temperature resistant settings of cable structures usually choose to add various thermal insulation and heat-insulating materials to the inner layer of the cable to isolate the introduction of heat.
[0003] Although the above-mentioned structure can achieve the effect of the cable's resistance to external high temperatures to a certain extent, when heat is generated inside the cable, the heat dissipation capacity is correspondingly reduced.
[0004] This solution provides an external high-temperature resistant structure for connecting cables, which can achieve high-temperature resistance through structural settings while also improving heat dissipation effects. Utility Model Content
[0005] The utility model aims to at least solve the problem in the prior art that heat inside and outside the cable cannot be well dissipated.
[0006] The present solution provides an external high-temperature resistant structure for connecting cables, which is achieved by the following specific technical means: it includes a cable body, the outer wall of the cable body is provided with a protective sleeve, and the outer circumference of the protective sleeve is provided with multiple groups of grooves along the length direction. The opening of the grooves enables the protective sleeve to form multiple groups of protrusions in the circumferential direction; a group of thermal conductive wires passes through each group of the protrusions, and at the same time, a heat dissipation hole is provided in the protrusion at each interval, and the heat dissipation hole passes through the thermal conductive wire and the two ends of the heat dissipation hole are respectively connected to the grooves on both sides of the group of protrusions.
[0007] Preferred technical solution 1: The heat dissipation holes on the multiple groups of protrusions located in the same plane are penetrated by heat-conducting rings, which are simultaneously connected to multiple groups of heat-conducting wires through the heat-conducting rings to conduct the heat introduced from the contact points to the surrounding side of the protective sleeve.
[0008] Preferred technical solution 2: The protective sleeve is rotatably mounted on the cable body, so that the protective sleeve as a whole can rotate on the cable body.
[0009] Preferred technical solution three: the heat-conducting rings are evenly spaced in the length direction of the protective sleeve.
[0010] Preferred technical solution four: The protective sleeves are distributed in multiple groups along the length direction of the cable body.
[0011] Preferred technical solution four: an inner tube is rotated in the inner cavity of the protective sleeve, and the inner tube is sleeved on the cable body.
[0012] The above structure enables this solution to have the following beneficial effects:
[0013] 1. By setting a protective cover on the outside of the cable body, the use of protrusions, thermal wires and thermal rings can reduce the contact area with high-temperature objects, increase the heat dissipation surface area, and diffuse the heat introduced from the contact point to the surrounding area as much as possible to avoid heat accumulation;
[0014] 2. The protective cover can be rotated on the cable body, so that when rapid heat dissipation is required, it can be achieved by rotating the protective cover;
[0015] 3. The setting of the protective cover not only helps to isolate and protect the cable from external heat, but also helps to conduct internal heat away. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0024] See also Figure 2 and Figure 4-Figure 5The external high-temperature resistant structure of the connecting cable includes a cable body 1. The outer wall of the cable body 1 is provided with a protective sleeve 2. The protective sleeve 2 is made of high-temperature resistant material and is not easily deformed. A plurality of groups of grooves 21 are provided on the outer periphery of the protective sleeve 2 along the length direction. The opening of the grooves 21 enables the protective sleeve 2 to form a plurality of groups of protrusions 22 in the circumferential direction. The outer end surface of the protrusion 22 is covered with a wear-resistant layer 24. The presence of the plurality of groups of protrusions 22 effectively reduces the contact area between the cable and the high-temperature object and improves the outer surface of the protective sleeve 2.
[0025] A group of thermal conductive wires 4 passes through each group of protrusions 22, and a heat dissipation hole 23 is opened in each protrusion 22 at a certain interval. The heat dissipation hole 23 passes through the thermal conductive wire 4 and the two ends are respectively connected to the grooves 21 on both sides of the group of protrusions 22. The setting of the thermal conductive wire 4 is used to conduct the heat introduced into the protrusion 22 at the contact point of the high-temperature object in the length direction of the protective sleeve 2, so as to avoid heat accumulation at the contact point position, and dissipate the heat of the thermal conductive wire 4 through the heat dissipation hole 23.
[0026] See also Figure 1 and Figure 5 , an external high-temperature resistant structure for connecting cables, a heat-conducting ring 5 is passed through the heat-dissipating holes 23 on the multiple groups of protrusions 22 located in the same plane, and is connected to multiple groups of heat-conducting wires 4 at the same time through the heat-conducting ring 5, which is used to conduct the heat introduced from the contact point to the side of the protective sleeve 2 to improve the heat dissipation effect. At the same time, the part of the heat-conducting ring 5 passing through the heat-dissipating hole 23 is located in the groove 21, and can directly exchange heat with the outside air. The heat-conducting rings 5 are evenly spaced in the length direction of the protective sleeve 2.
[0027] See also Figures 1-4 , the external high-temperature resistant structure of the connecting cable, the protective cover 2 is rotatably sleeved on the cable body 1, so that the protective cover 2 as a whole can rotate on the cable body 1. When rapid heat dissipation is required, such as after the equipment stops or the contact point is replaced, by rotating the protective cover 2 at the original contact point position, the protrusion 22 on the protective cover 2 acts as a blade to stir the surrounding air, increase the air flow rate, and accelerate heat dissipation; the protective cover 2 is distributed in multiple groups along the length direction of the cable body 1. While the multiple groups of protective covers 2 cooperate to provide high-temperature protection for the cable body 1, they can also rotate independently.
[0028] See also Figure 3 , the external high temperature resistant structure of the connecting cable, the cable body 1 is formed by using an insulating skin 11 to cover the wire harness 12.
[0029] See also Figure 1-Figure 5 , an external high-temperature resistant structure of the connecting cable, an inner tube 3 is rotated in the inner cavity of the protective sleeve 2, the inner tube 3 is fixedly mounted on the cable body 1, and the inner tube 3 is a hard tube, and can transfer the heat of the cable body 1 to the protective sleeve 2, thereby realizing heat dissipation inside the cable body 1, and the setting of the inner tube 3 can also increase the smoothness of the rotation of the protective sleeve 2.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
