Technical Field

[0001] The utility model belongs to the technical field of special cables, and particularly relates to a wear-resistant elastomer special soft power cable. Background Technique

[0002] The wear-resistant elastomer special soft power cable is a cable with special design and material composition, mainly used for transmitting power, energy and information of electrical equipment in special environments and special equipment. The cable has a soft structure, high mechanical strength, high wear resistance and tear resistance, so it is suitable for transmitting power, energy and information of electrical equipment in special field environments;

[0003] At present, it is found in the actual application of the existing wear-resistant elastomer special soft power cable that due to its good bending performance brought by its elastic characteristics, it is often used in places that require frequent bending. However, excessive bending or stretching may cause damage to the internal structure of the cable, such as conductor fracture, insulation layer rupture, etc., thus affecting the performance and service life of the cable and being unfavorable for the long-term stable use of the cable;

[0004] To solve the above problems, a wear-resistant elastomer special soft power cable is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wear-resistant elastomer special soft power cable, which solves the problems put forward in the above background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a wear-resistant elastomer special soft power cable, including: a cable core and an inner extruded layer outside it; a protective sleeve is arranged outside the inner extruded layer, and a reinforcing rib for limiting the bending angle is arranged inside the protective sleeve. An air cavity is opened inside the reinforcing rib to form a buffer when encountering external extrusion to ensure the stability of the cable structure; a limiting frame is arranged outside the cable core, the limiting frame is installed on the cable core production conveyor line, and extrusion rollers for extruding the protective sleeve to wrap the cable core to form an assembly are arranged on both sides of the limiting frame. At this time, the protective sleeve and the cable core are simultaneously extruded to form an outer extruded layer in the outer region.

[0008] Further, limiting protrusions for increasing the contact area with the outer extruded layer are arranged outside the protective sleeve, and a sealing gasket is arranged outside one end of the protective sleeve.

[0009] Further, shaft seats for rotatably installing the protruding shaft bodies at both ends of the extrusion roller are arranged inside both ends of the limiting frame.

[0010] Further, cross plates are arranged on both sides of the protective sleeve, and the reinforcing rib is installed inside adjacent cross plates.

[0011] Further, a protruding positioning ball is provided on the outer side of the cross plate on one side of the protective sleeve, and a positioning groove for snap-fitting connection of the positioning ball is provided inside the cross plate on the other side of the protective sleeve.

[0012] Further, the reinforcing ribs are arranged at equal intervals inside the protective sleeve, and the abutment of adjacent reinforcing ribs is used to prevent the cable core from bending excessively.

[0013] Further, the protective sleeve is stored through an external winding mechanism, and is placed outside the upper and lower ends of the cable core during the production of the cable core to form an assembly.

[0014] The utility model has the following beneficial effects:

[0015] By installing the protective sleeve, when the cable core bends, the adjacent reinforcing ribs can be mutually pressed against each other to prevent excessive bending. At the same time, the air cavity is used to enhance the buffering performance against external forces, so as to prevent structural damage when bending and when being externally pressed. Compared with the existing elastic cables, the bending angle can be limited without worrying about excessive bending causing the internal core to break, so as to ensure the stable operation of the cable and extend its service life.

[0016] In the utility model, the cable core and the protective sleeve are assembled by being inserted into the inside of the limiting frame, and the adjacent protective sleeves are butted against each other by cooperating with the pressing rollers to wrap the cable core to form a protection. At this time, the protective sleeve and the cable core can be simultaneously subjected to extrusion operation to be fixed inside the covering structure. The operation is simple and can conveniently realize the diversification of the functions of the cable, so that the cable can more stably adapt to special places to improve its use effect and reduce the failure rate.

[0017] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. Description of the Drawings
