Description

Technical Field

[0001] This utility model relates to the field of coaxial cable technology, and in particular to coaxial cables with electromagnetic shielding. Background Technology

[0002] In the use of coaxial cables, there are situations where two cables are connected. However, ordinary cables lack auxiliary connection measures, which leads to a reduction in the sealing and insulation effect after the cable connection, affecting the practicality of the coaxial cable. The "Multifunctional Coaxial Cable" disclosed on the China Patent Network, with application number "201820296957.9", uses a buffer layer between the outer jacket and the shielding layer. This cable has three advantages: first, it facilitates the processing of annular grooves on the coaxial cable; second, it protects the coaxial cable, reducing the possibility of scratches and mitigating the impact of temperature on the cable; and third, the buffer layer has a low density and does not absorb water, which is beneficial for the coaxial cable to float on the water surface, thereby improving the practicality of the cable. However, there is still a risk of reduced sealing and insulation effect during the connection process. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, to provide a coaxial cable with electromagnetic shielding, to improve the convenience of connecting multiple cable segments, to reduce the impact on the sealing and insulation of the connected multiple cable segments, and to improve the stability of the connected multiple cable segments.

[0004] This utility model also provides a coaxial cable with the above-mentioned electromagnetic shielding, comprising: a sheath, wherein a battery core, an insulating layer, and a shielding layer are disposed inside the sheath, the side surface of the shielding layer is in contact with the inner wall of the sheath, the insulating layer is located inside the shielding layer and inside the battery core, a ferrule is disposed on the surface of the shielding layer, the side surface of the ferrule is in contact with the inner wall of the sheath, and a traction hole is disposed on the surface of the ferrule and the surface of the shielding layer, wherein a socket strip is disposed inside the traction hole.

[0005] According to the electromagnetically shielded coaxial cable of this invention, the clamping sleeve and the insulation layer are made of the same material, and the traction hole does not completely penetrate the shielding layer. This improves the effectiveness of the clamping sleeve.

[0006] According to the electromagnetically shielded coaxial cable of this utility model, the surface of the sheath is provided with a marking sleeve, the marking sleeve being made of the same material as the sheath, and the marking sleeve being distributed opposite to the binding sleeve. This improves the convenience of determining the cutting point.

[0007] According to the electromagnetically shielded coaxial cable of this utility model, the side surface of the sheath is provided with a positioning groove, and the marking sleeve is located inside the positioning groove. This improves the stability of the marking sleeve during operation. Beneficial effects

[0008] Compared with existing technologies, this electromagnetically shielded coaxial cable features a bundled structure in its internal sections using a bundled sleeve, socket strip, and traction hole. This increases the compactness of the cable's internal structure and reduces the risk of moisture transmission. The socket strip and traction hole provide a means of securing multiple cable segments, improving the stability and sealing effect of the connection. The marking sleeve helps workers identify the location of the bundled sleeve, enhancing their ability to determine the socket connection area. Attached Figure Description

[0016] 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.

[0017] Reference Figure 1-4This utility model embodiment features an electromagnetically shielded coaxial cable, comprising: a sheath 1, inside which are disposed a battery core 3, an insulating layer 4, and a shielding layer 5. The side surface of the shielding layer 5 contacts the inner wall of the sheath 1. The insulating layer 4 is located inside the shielding layer 5 and inside the battery core 3. These components cooperate to form the basic structure of the electromagnetically shielded coaxial cable. The insulating layer 4 is used to increase the insulation of the cable. The shielding layer 5 is a common material used for shielding electromagnetic fields in power lines. A marking sleeve 2 is provided on the surface of the sheath 1. The marking sleeve 2 is made of the same material as the sheath 1 and is distributed opposite to the binding sleeve 6. The marking sleeve 2 is used to assist workers in determining the position of the binding sleeve 6. A positioning groove 9 is provided on the side surface of the sheath 1. The marking sleeve 2 is located inside the positioning groove 9, which is used to increase the stability of the marking sleeve 2.

[0018] Specifically, the sheath 1 directly prevents external impurities from contacting important parts of the cable, the insulation layer 4 increases the risk of power leakage, and the shielding layer 5 directly reduces the impact of external electromagnetic forces on the cable's performance. When the cable needs to be cut, the position of the marking sleeve 2 is compared with the position of the binding sleeve 6, so the cutting point of the cable can be directly determined by the position of the marking sleeve 2, thereby ensuring that the pulling hole 8 and the socket strip 7 are exposed, and the staff can directly perform the socket connection work of the cable.

[0019] A ferrule 6 is provided on the surface of the shielding layer 5. The side surface of the ferrule 6 contacts the inner wall of the sheath 1. The ferrule 6 is used to increase the compactness of the internal components of the sheath 1 and enhance the cable's anti-penetration capability. Both the surface of the ferrule 6 and the surface of the shielding layer 5 are provided with traction holes 8. A socket strip 7 is provided inside the traction hole 8. The ferrule 6 and the insulation layer 4 are made of the same material. The traction hole 8 does not completely penetrate the shielding layer 5. The traction hole 8 cooperates with the socket strip 7 to improve the convenience of connecting multiple cable segments. The socket strip 7 has the property of hot melt adhesion, thereby improving the stability after the multiple cable segments are connected.

[0020] Specifically, after external moisture seeps into the cable, the additional tightness of the internal components of the sheath 1 by the clamp sleeve 6 prevents moisture from flowing inside the cable. When multiple cable segments need to be connected, after the worker cuts the cable according to the marking sleeve 2, the traction hole 8 and the socket rubber strip 7 are exposed. Then, the socket rubber strip 7 of one cable is pulled out and inserted into the traction hole 8 of another cable to complete the cable connection. At the same time, the stability of the two cables after connection is increased by heating the socket rubber strip 7 during the connection process. The heat-melted socket rubber strip 7 is pressed to completely seal the traction hole 8, thereby preventing moisture from flowing through the traction hole 8.

[0021] Working principle: When connecting multiple cable segments, the cutting point of the cable is determined according to the position of the marking sleeve 2. After cutting the cable according to the position of the clamp sleeve 6, the socket strip 7 inside the first cable is pulled out and inserted into the second cable. At the same time, the socket strip 7 can be heated during the insertion process. Then, the two cables are connected. In this way, the stability of the cable connection is increased by using the heat-melted socket strip 7.

[0022] 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.
