Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a combined cable. Background Art

[0002] Cables are usually rope-like combined cables made up of several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and often twisted around a center, with the entire outside covered with a highly insulating covering.

[0003] Sometimes, when using traditional cables, in order to extend the use length of the cables, two cables are connected to each other. When connecting, a section of the insulation skin is cut off at one end of the two cables, and then the wires inside the two cables are accurately and orderly intertwined and connected. Then, insulating tape is wrapped around the connection before use. However, in actual use, it is found that the two cables are only connected to each other and reinforced by the winding of the insulation skin. This method has poor connection stability. When the cable is used, if the pulling and swinging force is too large, the connection of the wires will become loose or even detached, which will affect the normal use of the cable and pose certain safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the prior art, two cables only have the conductors connected to each other and the insulation skins are wound and reinforced, and such a connection has poor stability. When the cable is used, if the pulling and swinging force is too large, the connection of the conductors may become loose or even detached, thereby affecting the normal use of the cable and having certain safety hazards. A combined cable is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined cable, comprising two cable body and a fixing device, the inner walls of the two cable bodies are respectively fixedly connected with a plurality of conductors, the two cable bodies are connected by the fixing device, the fixing device comprises two fixing rings, the two fixing rings are respectively sleeved on the arc surfaces of the two cable bodies, two card grooves are respectively provided on one side surface of the two fixing rings, two card blocks are respectively fixedly connected on the arc surfaces of the two cable bodies, the two card blocks are respectively clamped with the inner walls of the two card grooves, two fixing blocks are respectively fixedly connected on the arc surfaces of the two fixing rings, fixing rods are respectively inserted through the surfaces of the two fixing blocks, threads are respectively provided at both ends of the fixing rods, and nuts are respectively threadedly connected at both ends of the fixing rods.

[0006] The effect achieved by the above components is that the cable body can be more stable when connected and assembled, and it is not easy to loosen or detach at the connection port due to excessive pulling and fiddling during use, thereby ensuring the normal use of the cable body and reducing certain safety hazards.

[0007] Preferably, washers are respectively sleeved on both ends of the fixing rod, and the washers are metal rings, and the washers abut against the nuts.

[0008] The effect achieved by the above components is that, through the provision of the washer, the nut is more stably threadedly connected to the fixing rod, and is not prone to rotational loosening, thereby further improving the stability of the fixing device in use.

[0009] Preferably, inner walls of the two fixing rings are respectively fixedly connected with protective rings, and the protective rings are rubber rings.

[0010] The effect achieved by the above components is that by setting the protective ring, when the fixing ring is set on the cable body, it is not easy to cause the skin of the cable body to be damaged due to excessive contact and extrusion force, thereby damaging the cable body.

[0011] Preferably, two stabilizing plates are fixedly connected to the arc surfaces at both ends of the fixing rod, two stabilizing grooves are respectively provided on both sides of the surfaces of the two fixing blocks, and the two stabilizing plates are respectively plugged into the inner walls of the two stabilizing grooves.

[0012] The effect achieved by the above components is: through the plug-in arrangement of the stabilizing plate and the stabilizing groove, the fixing rod and the fixing block are more stable and less likely to rotate when connected, thereby making it more convenient to connect and install the nut.

[0013] Preferably, two reinforcement plates are fixedly connected to the surface of the fixing rod, and the cross-sections of the two reinforcement plates are "U"-shaped.

[0014] The effect achieved by the above components is: through the setting of the reinforcement plate, a certain connection stability can be formed between the two fixing rods, so that the fixing rods are more stable and less likely to deform, and the connection of the cable body is better reinforced.

[0015] Preferably, a protective device is provided at the connection between the two cable bodies, and the protective device includes a protective cover, which is provided on the arc surface of the connection between the two cable bodies. Four positioning plates are fixedly connected to the surface of the protective cover, and the four positioning plates are grouped in pairs, and the sides of the positioning plates in the same group that are close to each other are clamped with the surface of the reinforcement plate.

[0016] The effect achieved by the above components is that when the cable body is connected and installed, the interface can be better protected and is not prone to contact and collision with external objects, thereby ensuring the normal connection and use of the cable body.

[0017] Preferably, screw holes are respectively provided on the sides of the surfaces of the positioning plates in the same group that are close to each other, and bolts are threadedly connected to the inner walls of the screw holes.

[0018] The effects achieved by the above components are: through the setting of the bolts, the installation of the protective cover is made more stable and firm, thereby better protecting the connection interface of the cable body, thereby improving the use effect of the protective device.

[0019] Preferably, one end of the bolt is fixedly connected to an operating block, and a surface of the operating block is provided with a plurality of anti-slip protrusions.

[0020] The effects achieved by the above components are: through the setting of the operating block, the bolt can be rotated more conveniently during use, thereby better reinforcing the position of the protective cover and improving the stability of the protective device.

The wires 2 on 1 are accurately and effectively installed, and then wrapped with insulating tape, and then the two fixing rings 31 are respectively installed on the two cable bodies 1, so that the card slots 32 on the fixing rings 31 are engaged with the card blocks 33 on the cable body 1, and then the same fixing rods 35 are inserted through the fixing blocks 34 on both sides of the two fixing rings 31, and then nuts 36 are threadedly installed on both ends of the two fixing rods 35, so that the nuts 36 contact and squeeze on the surface of the fixing blocks 34. At this time, the cable body 1 can be more stable when connected and combined, and it is not easy to loosen and detach at the connection port due to excessive pulling and fiddling during use, thereby ensuring the normal use of the cable body 1 and reducing certain safety hazards.
