Description

Technical Field

[0001] This utility model relates to the field of cables, and more specifically, to a shielded multi-core control cable that is easy to connect and manage. Background Technology

[0002] Control cables are primarily used to transmit electrical energy directly from the distribution points of a power system to various electrical equipment and appliances. With the rapid development of industrial automation, robotics, aerospace, and other fields, the performance requirements for control cables are becoming increasingly stringent.

[0003] Traditional control cables are often complex to lay out and manage due to a lack of flexible and reliable connection methods. Cable fixing and connection typically require a large amount of auxiliary materials and tools, increasing the difficulty of installation and maintenance. Traditional control cable connectors and fasteners often have fixed sizes and shapes, making it difficult to accommodate cables of different diameters. This necessitates preparing various connectors or fasteners of different sizes in practical applications, increasing cost and complexity. Traditional control cables often lack sufficient anti-interference capabilities, making them susceptible to external electromagnetic interference. This can lead to unstable signal transmission, affecting the normal operation and performance of the system. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a shielded multi-core control cable that is easy to connect and manage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control cable, comprising multiple cable bodies and multiple connecting units, wherein each connecting unit is capable of connecting any two adjacent cable bodies, and each connecting unit includes a connecting portion and two wrapping portions fixedly connected to the connecting portion. The connecting portion has an I-shaped structure, and the wrapping portions have a C-shaped structure. The connecting portion includes two first horizontal plates and a first vertical plate connecting the two first horizontal plates. Two first elastic rubber sheets are connected between the two first horizontal plates, and the two first elastic rubber sheets are respectively located on the two sides of the first vertical plate. On the side, the wrapping part includes two second horizontal plates and a second vertical plate connecting the two second horizontal plates. A second elastic rubber sheet is connected between the two second horizontal plates. Two first elastic rubber sheets correspond to the two second elastic rubber sheets respectively. The first elastic rubber sheets and the corresponding second elastic rubber sheets can wrap a cable body. The cable body includes an outer sheath, a flame-retardant layer, a main shielding layer and a wrapping tape layer from the outside to the inside. The wrapping tape layer has multiple cable cores. The cable core includes an inner sheath, a sub-shielding layer and a conductor from the outside to the inside. The conductor includes a conductor and an insulation layer covering the conductor.

[0006] Furthermore, the first elastic rubber sheet connects the ends of the two first horizontal plates, and the second elastic rubber sheet connects the ends of the two second horizontal plates.

[0007] Thus, the first elastic rubber sheet and the second elastic rubber sheet form an elastic clamping structure.

[0008] Furthermore, two first receiving grooves that mate with the cable body are formed between the first vertical plate and the two first horizontal plates, and a second receiving groove that mates with the cable body is formed between the second vertical plate and the two second horizontal plates.

[0009] Thus, the cable body can be accommodated in a first accommodating groove and a second accommodating groove.

[0010] Furthermore, the wrapping part and the connecting part are fixedly connected by fixing bolts, the second horizontal plate has a mounting through hole that mates with the fixing bolts, and the first horizontal plate has a threaded hole that mates with the fixing bolts.

[0011] This ensures a stable connection between the wrapping part and the connecting part.

[0012] Furthermore, at least two connection units are connected between two adjacent cable bodies.

[0013] This makes the connection between the two cable bodies more secure.

[0014] Furthermore, the multiple cable cores are divided into a first cable core and multiple second cable cores, with the multiple second cable cores surrounding the first cable core.

[0015] This results in high structural stability of the cable body.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The control cable of this application can connect and fix two adjacent cable bodies through multiple connection units, or connect multiple cable bodies together, thereby making the cable layout and organization more flexible and simple, and reducing the difficulty of installation and maintenance.

[0018] 2. The control cable of this application, with its first elastic rubber sheet and second elastic rubber sheet, enables the connection unit to adapt to cable bodies of different diameters, thus achieving high applicability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-5 The diagram illustrates a shielded multi-core control cable for easy connection and organization, comprising multiple cable bodies 1 and multiple connecting units. Each connecting unit can connect any two adjacent cable bodies 1. Each connecting unit includes a connecting portion 2 and two wrapping portions 3 fixedly connected to the connecting portion 2. The connecting portion 2 has an I-shaped structure, and the wrapping portions 3 have a C-shaped structure. The connecting portion 2 includes two first horizontal plates 2.1 and a first vertical plate 2.2 connecting the two first horizontal plates 2.1. Two first elastic rubber sheets 2.3 are connected between the two first horizontal plates 2.1, and the two first elastic rubber sheets 2.3 are located on opposite sides of the first vertical plate 2.2. The wrapping portions 3 include two second horizontal plates 3.1 and... A second vertical plate 3.2 connects two second horizontal plates 3.1. A second elastic rubber sheet 3.3 is connected between the two second horizontal plates 3.1. Two first elastic rubber sheets 2.3 correspond to two second elastic rubber sheets 3.3 respectively. The first elastic rubber sheets 2.3 and the corresponding second elastic rubber sheets 3.3 can wrap a cable body 1. The cable body 1 includes, from the outside to the inside, an outer sheath 1.1, a flame retardant layer 1.2, a main shielding layer 1.3, and a wrapping layer 1.4. The wrapping layer 1.4 has multiple cable cores. The cable core includes, from the outside to the inside, an inner sheath 1.5, a sub-shielding layer 1.6, and a conductor. The conductor includes a conductor 1.8 and an insulation layer 1.7 covering the conductor 1.8.

[0028] The first elastic rubber sheet 2.3 connects the ends of the two first horizontal plates 2.1, and the second elastic rubber sheet 3.3 connects the ends of the two second horizontal plates 3.1. Two first receiving grooves that mate with the cable body 1 are formed between the first vertical plate 2.2 and the two first horizontal plates 2.1, and a second receiving groove that mates with the cable body 1 is formed between the second vertical plate 3.2 and the two second horizontal plates 3.1. The wrapping part 3 and the connecting part 2 are fixedly connected by fixing bolts (not shown in the figure). The second horizontal plate 3.1 has mounting through holes that mate with the fixing bolts, and the first horizontal plate 2.1 has threaded holes that mate with the fixing bolts. At least two connecting units are connected between two adjacent cable bodies 1. Multiple cable cores are divided into one first cable core and multiple second cable cores, with the multiple second cable cores surrounding the first cable core.

[0029] Working principle: The control cable of this application can connect and fix two adjacent cable bodies through the connection unit. Using multiple connection units can make the connection between the two cable bodies more stable. Multiple connection units can also connect multiple cables, thereby making the cable layout and organization more flexible and simple, and reducing the difficulty of installation and maintenance.

[0030] During installation, the connecting part is placed between two adjacent cable bodies, causing each cable body to press against two first elastic rubber sheets and be accommodated in one of the two first receiving grooves. Next, two wrapping parts are fitted onto the two cable bodies, causing each cable body to press against two second elastic rubber sheets and be accommodated in one of the two second receiving grooves. Finally, the two wrapping parts and the connecting part are fixed together using fixing bolts. The deformed first and second elastic rubber sheets clamp and wrap the cable bodies between the wrapping parts and the connecting part, thus fixing the cable bodies under the elastic force of the rubber sheets. Furthermore, because the connecting unit uses elastic rubber sheets, it can fix cable bodies of different diameters, offering high applicability. If multiple cable bodies need to be connected, repeat the above steps, installing at least two connecting units between each adjacent cable body.

[0031] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
