Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a halogen-free control flexible cable. Background Technology

[0002] Cables are typically rope-like cables made up of several or groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated. They are generally used for communication connections in crystallizer pulse width adjustment.

[0003] However, currently, the multiple conductive cores inside cables on the market are installed in direct contact. When the cable is twisted, the conductive cores will bend, which will increase the number of times the conductive cores rub against each other, causing damage to the conductive cores and thus shortening the service life of the flexible cable.

[0004] The existing Chinese patent CN214312697U describes a halogen-free control flexible cable. In addressing the aforementioned issues, the two ends of the steel wire rope are screwed into the threaded groove. However, in actual use, when one end of the steel wire rope is tightened and the other end is tightened, the steel wire rope will twist. Since the length of the steel wire rope is limited, the twisted steel wire rope will cause the cable to be in a bent state, thus affecting the performance of the cable. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a halogen-free control flexible cable.

[0006] One of the objectives of this utility model is achieved through the following technical solution:

[0007] A halogen-free control flexible cable includes a protective sheath and a core. The outer edge of the protective sheath is fixedly fitted with several fixing rings. Several steel wire ropes are arranged between two adjacent fixing rings. Several grooves are formed on both sides of each fixing ring. Several first anti-slip strips are fixedly connected to the inner cavity of each groove. The two ends of the steel wire ropes are movably inserted into the inner cavity of adjacent grooves. A pressure plate is provided in the inner cavity of each groove. Several second anti-slip strips are fixedly connected to the inner side of the pressure plate. Several screw holes are formed on the outer edge of the fixing rings. Screws are inserted into the inner cavity of each screw hole. The screws extend into the inner cavity of adjacent grooves and are movably fitted with springs.

[0008] Furthermore, the protective sleeve is fitted over the outside of the core, and the protective sleeve is made of halogen-free, low-smoke, flame-retardant polyolefin material.

[0009] Furthermore, the cross-section of the pressure plate is arc-shaped, and the arc-shaped opening faces the wire rope.

[0010] Furthermore, the screw and the pressure plate are fitted together, and the screw and the screw hole are connected by a thread.

[0011] Furthermore, the spring is fixedly connected to the inner cavity of the groove, and the spring is fixedly connected to the pressure plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a halogen-free control flexible cable. During use, one end of a steel wire rope is inserted into the corresponding groove cavity, and then the screw is tightened. The screw pushes the pressure plate towards the steel wire rope, while the spring stretches until the second anti-slip strip on the pressure plate comes into contact with the steel wire rope, thus fixing the steel wire rope in the groove cavity. The steel wire rope arrangement keeps the flexible cable straight between the two fixing rings, thereby preventing the flexible cable from bending and improving its performance. Compared with the prior art, the steel wire rope of this device will not twist during installation, thus preventing the steel wire rope from changing length due to twisting, and thus preventing the flexible cable from bending, thereby ensuring the performance of the flexible cable.

[0014] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0027] Please see Figure 1-8 This utility model provides a technical solution: a halogen-free control flexible cable, including a protective sleeve 1 and a wire core 2. The protective sleeve 1 is sleeved on the outside of the wire core 2. The protective sleeve 1 is made of halogen-free, low-smoke, flame-retardant polyolefin material. Several fixing rings 3 are fixedly sleeved on the outer edge of the protective sleeve 1. Several steel wire ropes 4 are provided between two adjacent fixing rings 3. Several grooves 5 are opened on both the left and right sides of the fixing rings 3. Several first anti-slip strips 7 are fixedly connected to the inner cavity of the grooves 5. The two ends of the steel wire ropes 4 are movably inserted into the inner cavity of the adjacent grooves 5.

[0028] The inner cavity of the groove 5 is provided with a pressure plate 6. The cross-section of the pressure plate 6 is arc-shaped, and the arc-shaped opening faces the wire rope 4. Several second anti-slip strips 8 are fixedly connected to the inner side of the pressure plate 6. Several screw holes 11 are opened on the outer edge of the fixing ring 3. Screws 10 are inserted into the inner cavity of the screw holes 11. The screws 10 and the pressure plate 6 are in contact with each other. The screws 10 and the screw holes 11 are connected by threads. The screws 10 extend to the inner cavity of the adjacent groove 5 and are movably sleeved with springs 9. The springs 9 are fixedly connected to the inner cavity of the groove 5 and are fixedly connected to the pressure plate 6.

[0029] Working Principle: This utility model discloses a halogen-free control flexible cable. During use, one end of the steel wire rope 4 is inserted into the inner cavity of the corresponding groove 5. The steel wire rope 4 is in contact with several first anti-slip strips 7. Then, the screw 10 is tightened, and the screw 10 rotates in the inner cavity of the screw hole 11. The screw 10 moves into the inner cavity of the groove 5, and pushes the pressure plate 6 towards the steel wire rope 4. At the same time, the spring 9 is stretched until the second anti-slip strip 8 on the pressure plate 6 is in contact with the steel wire rope 4, thereby fixing the steel wire rope 4 in the inner cavity of the groove 5. By setting the steel wire rope 4, the flexible cable can be kept in a straight state between the two fixing rings 3, thereby avoiding bending of the flexible cable and improving its performance. Compared with the prior art, the steel wire rope 4 of this device will not twist during installation, thereby avoiding changes in the length of the steel wire rope 4 due to twisting, and thus preventing the flexible cable from being in a bent state, thereby ensuring the performance of the flexible cable.
