Description

Technical Field

[0001] This utility model relates to the field of torsion-resistant cable technology, and in particular to a highly flexible torsion-resistant cable for robots. Background Technology

[0002] Flexible drag chain cables, while meeting the same electrical requirements, have a smaller outer diameter and lighter weight than other similar cables, and exhibit excellent bending performance. Currently, highly flexible cables are increasingly widely used in the automation industry. Belonging to the special cable series, highly flexible cables possess the ability to frequently bend and move. In industrial automation applications, these cables also possess oil resistance, abrasion resistance, bending resistance, dragging resistance, and friction resistance. With the rapid development of global informatization, the expanding application areas of industrial automation, the comprehensive improvement of home multimedia levels, and the explosive growth of electronic and electrical components, the market potential of highly flexible drag chain cables is increasing daily.

[0003] Existing flexible torsion cables increase ease of use when connected to robots due to their flexibility. However, traditional flexible torsion cables, while adding various effects to flexibility during production and use to achieve efficient soft torsion, are prone to internal copper wire breakage or overall structural damage when subjected to pressure, thus failing to provide flexible support and protect the internal copper wires. Utility Model Content

[0004] The purpose of this invention is to provide a highly flexible torsion-resistant cable for robots, which solves the problem that when the cable is subjected to pressure, the internal copper wires are easily broken or the overall structure is damaged, thus failing to achieve the function of flexible support and protection of the internal copper wires.

[0005] To achieve the above objectives, a highly flexible torsion-resistant cable for robots is provided, comprising: an outer protective layer of the cable; a braided layer fixedly connected to the inner side of the outer protective layer; an inner lining layer fixedly connected to the inner side of the braided layer; a wrapping layer fixedly connected to the inner side of the inner lining layer; a flexible support inner ring fixedly connected to the inner side of the wrapping layer; a filling layer fixedly connected to the inner side of the flexible support inner ring; a first flexible support strip and a second flexible support strip fixedly connected to the outer side of the flexible support inner ring and the outer protective layer of the cable, respectively; and a plurality of copper bodies disposed inside the filling layer.

[0006] According to the aforementioned highly flexible torsion-resistant cable for robots, one end of the first flexible support bar is fixedly connected to a protrusion.

[0007] According to the aforementioned highly flexible torsion-resistant cable for robots, a slot is provided on the inner side of the second flexible support bar, and the slot and the protrusion are inserted into each other.

[0008] According to the aforementioned highly flexible torsion-resistant cable for robots, the number of the first flexible support bar and the second flexible support bar is four.

[0009] According to the aforementioned highly flexible torsion-resistant cable for robots, the groove and the edge of the protrusion are arranged in an arc shape.

[0010] The above-mentioned solution has the following beneficial effects:

[0011] This utility model incorporates a supporting inner ring, a first flexible support strip, and a second flexible support strip. The first and second flexible support strips increase the contact between the flexible inner ring and the outer protective layer of the cable, and are connected by protrusions and slots to achieve a firm support effect. When the cable is subjected to pressure, the first and second flexible support strips can provide support through compression. This structure protects the inner copper body, reducing breakage and enhancing the cable's protective function.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model discloses a highly flexible torsion-resistant cable for robots, comprising: an outer protective layer 1; a braided layer 8 fixedly connected to the inner side of the outer protective layer 1; the braided layer 8 using tin-plated copper wire shielding braid; an inner lining layer 9 fixedly connected to the inner side of the braided layer 8; the inner lining layer 9 using a non-hygroscopic, halogen-free, low-smoke flame-retardant material to ensure the cable's safety and environmental friendliness; a wrapping layer 10 fixedly connected to the inner side of the inner lining layer 9; the wrapping layer 10 using polyester tape, possessing good tensile strength and preventing cable loosening; and a flexible support inner ring 2 fixedly connected to the inner side of the wrapping layer 10; the flexible support inner ring 2 using rubber. The flexible support inner ring 2 is made of adhesive material and provides a ring-shaped support effect. A filling layer 11 is fixedly connected to the inner side of the flexible support inner ring 2. The filling layer 11 is made of flame-retardant material. The copper body 3 in the cable is inserted into the inner ring 2 of the flexible support. The filling layer 11 increases the filling effect and keeps the position of the copper body 3 fixed. A first flexible support strip 4 and a second flexible support strip 5 are fixedly connected between the outer side of the flexible support inner ring 2 and the outer protective layer 1 of the cable, respectively. The first flexible support strip 4 and the second flexible support strip 5 increase the contact effect between the flexible support inner ring 2 and the outer protective layer 1 of the cable. Several copper bodies 3 are arranged inside the filling layer 11.

[0022] One end of the first flexible support strip 4 is fixedly connected to a protrusion 7. When the cable is subjected to pressure, the first flexible support strip 4 and the second flexible support strip 5 can provide a certain support effect through compression, protecting the inner copper body 3 and reducing breakage damage. The inner side of the second flexible support strip 5 is provided with a slot 6. The protrusion 7 and the slot 6 are inserted to achieve a firm support effect. The setting of the protrusion 7 and the slot 6 can increase the concave-convex interlocking, improve the flexible torsion effect, and prevent stiff use. Furthermore, the first flexible support strip 4 and the second flexible support strip 5 can be cut off at the end without affecting the use effect. The slot 6 and the protrusion 7 are inserted and cooperate. There are four first flexible support strips 4 and two flexible support strips 5. With four strips, they can provide support when subjected to pressure in different positions, up, down, left, and right. The edges of the slot 6 and the protrusion 7 are arc-shaped, which can better match the circular shape of the cable.

[0023] Working principle: During use, the copper body 3 in the cable is inserted into the inner ring 2 of the flexible support, and the filling layer 11 is used to increase the filling effect and keep the position of the copper body 3 fixed. Then, the first flexible support strip 4 and the second flexible support strip 5 are set between the inner ring 2 of the flexible support and the outer protective layer 1 of the cable to increase the contact effect. They are connected by the protrusion 7 and the slot 6 to achieve a firm support effect. When the cable is subjected to pressure, the first flexible support strip 4 and the second flexible support strip 5 can provide a certain support effect by squeezing, protecting the inner copper body 3 and reducing breakage and damage.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
