Description

Technical Field

[0001] The present invention relates to the technical field of satellite communication station cable connection, and in particular to a cable connection structure between devices in a satellite communication station. Background Art

[0002] With the continuous advancement of electronic information technology, satellite communication stations, constructed from multiple electronic devices, have gained widespread application in both military and civilian fields. However, as the complexity of communication station electrical systems increases, the interconnecting cable networks between various devices in the system have become a significant factor affecting system reliability. While the reliability and environmental adaptability of individual devices are constantly being improved, the reliability and environmental adaptability of the cable network and cable connectors often become crucial factors affecting system reliability.

[0003] On the ground, equipment can be extremely dispersed, requiring long cable spans to connect them. Furthermore, the equipment often has height differences, making it very likely that accumulated water will flow along the cables to the connection points. Cables, while inherently protected by multiple layers of protection, offer little concern for their environmental protection. However, the connection between the cable plug and the device socket is often exposed to the elements, making this a vulnerable point in actual operation. Typically, after the plug and socket are connected, additional protection is required. Given the frequent assembly and disassembly of plugs and device sockets, sealing the connection with sealants is not recommended to enhance the protection level. Using sintered sockets would limit component selection and increase equipment cost. Using heat-shrinkable plastic tubing to cover the cable and socket connection to enhance protection levels does not meet the required level, and this approach significantly impacts operational processes and results in variable protection levels.

[0004] Therefore, how to ensure that the protection level of the connection between the cable plug and the device socket meets the actual requirements has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] As described in the background, on the ground, various devices may be extremely dispersed, requiring cables connecting them to span long distances. Furthermore, due to height differences between devices, accumulated water could easily flow along the cables to the connection point between them and the device. Cables, while inherently multi-layered, offer no inherent environmental protection. However, the connection between the cable plug and the device socket is often exposed to the elements, making this connection a weak point in actual operation. Typically, after the plug and socket are connected, additional protection is required. Given the frequent assembly and disassembly of the plug and device socket, sealing the connection with sealant is not an option to increase the protection level. Using a sintered socket would limit component selection and increase equipment costs. Using heat-shrinkable plastic tubing to cover the cable and socket connection to increase the protection level does not meet the required protection level, and this approach significantly impacts the operating process and exhibits discrete characteristics. Therefore, ensuring that the protection level at the connection between the cable plug and device socket meets practical requirements has become a pressing technical challenge for those skilled in the art.

[0041] To solve the above problems, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The present invention provides a cable connection structure between devices in a satellite communication station, comprising a socket 110, a cable 120, a sleeve 130, and a sealing member 140. The socket 110 is mounted on the device. A first accommodating chamber is formed inside the socket 110. The cable 120 is provided with a plug. The plug is inserted into the first accommodating chamber of the socket 110 to electrically connect the socket 110 of the device to the plug of the cable 120. The sleeve 130 can be slidably mounted on the cable along the axial direction of the cable 120. The sleeve 130 is detachably connected to the socket 110 so that the sleeve 130 and the socket 110 can be connected and disconnected multiple times. A second accommodating chamber is formed inside the sleeve 130. The sealing member 140 can be slidably mounted on the cable along the axial direction of the cable 120 and can be accommodated in the first accommodating chamber and the second accommodating chamber. Compared with the sealant sealing method, the plug of the cable 120 and the socket 110 of the device can be disassembled and assembled multiple times. Compared with the form of using a sintered socket 110, it does not limit the selection of devices and reduces costs. Compared with the form of using a heat-shrinkable plastic sleeve for protection, the compression deformation characteristics of the sleeve 130 and the seal 140 are utilized to envelop the connection, thereby improving the radial and axial waterproof level and electromagnetic shielding level of the connection between the plug of the cable 120 and the socket 110 of the device, effectively solving the EMC problem at the interface, and ensuring that the protection level of the connection between the plug of the cable 120 and the socket 110 of the device meets the actual requirements. At the same time, there is no need to change the existing manufacturing process of the cable 120, and the disassembly and assembly process does not require special tools, with good operability. The overall structure is simple, effectively controls costs, is suitable for a variety of complex electrical systems, and has good application prospects.

[0042] Specifically, in the example, Figure 1 、 Figure 2 and Figure 3As shown, the seal 140 includes an outer protective sleeve 141, a middle protective sleeve 142, an inner protective sleeve 143, and a reinforcement layer 144. The middle protective sleeve 142 is installed in the outer protective sleeve 141. The inner protective sleeve 143 is installed in the middle protective sleeve 142. The outer protective sleeve 141, the middle protective sleeve 142, and the inner protective sleeve 143 cooperate to provide water blocking in the radial and axial directions of the connection. At the same time, the middle protective sleeve 142 and the inner protective sleeve 143 also provide electromagnetic shielding. The reinforcement layer 144 is arranged between the outer protective sleeve 141 and the middle protective sleeve 142. The reinforcement layer 144 is flexible and can provide good mechanical properties. The reinforcement layer 144 is made of high modulus aramid, which has excellent chemical resistance and is acid and alkali resistant. The outer protective sleeve 141 is made of high-density polyethylene, which has excellent chemical resistance, electrical insulation, low-temperature resistance, and permeability, completely eliminating the problem of water seepage. The middle protective sleeve 142 includes a first tube 1421 and a first water-blocking material 1422. A buffer cavity 14211 is formed within the side wall of the first tube 1421 to facilitate deformation of the first tube 1421. The first water-blocking material 1422 is installed within the buffer cavity 14211. The first tube 1421 is made of conductive rubber, which has excellent electromagnetic shielding properties. The first water-blocking material 1422 is made of water-blocking grease or water-blocking yarn. Both water-blocking grease and water-blocking yarn are active water-blocking materials with strong water absorption and high expansion rate. They can absorb water strongly, expand rapidly, and prevent water penetration. The inner protective sleeve 143 includes a second tube 1431 and a second water-blocking material 1432. The second water-blocking material 1432 is disposed within the side wall of the second tube 1431. Second tube 1431 is made of conductive rubber, which provides excellent electromagnetic shielding. Second water-blocking material 1432 is made of water-blocking grease or water-blocking yarn. Both are active water-blocking materials with strong water absorption and high expansion rates. They can absorb water strongly, expand rapidly, and block water penetration.

[0043] Preferably, there are multiple buffer cavities 14211, evenly distributed along the circumference of the first tube 1421. Each adjacent buffer cavities 14211 are interconnected, enabling adaptive adjustment of deformation in multiple directions. Multiple first water-blocking materials 1422 are disposed within the buffer cavities 14211 in a one-to-one correspondence with the multiple buffer cavities 14211, achieving water-blocking functionality in multiple directions.

[0044] Preferably, there are multiple second water-blocking materials 1432 , which are evenly distributed along the circumference of the second tube body 1431 , to achieve water-blocking function in multiple directions.

[0045] Preferably, the seal 140 includes a first sealing section and a second sealing section. The first sealing section can be inserted into the first accommodating cavity. The second sealing section can be inserted into the second accommodating cavity. It should be noted that the first sealing section includes an outer protective sleeve 141, a middle protective sleeve 142, an inner protective sleeve 143, and a reinforcement layer 144. The second sealing section also includes an outer protective sleeve 141, a middle protective sleeve 142, an inner protective sleeve 143, and a reinforcement layer 144. The radial dimension of the first sealing section is smaller than the radial dimension of the second sealing section. This further improves the sealing performance.

[0046] Specifically, in the example, Figure 4 As shown, the cable connection structure between satellite communication station equipment also includes a locking pin 150, a locking rod 160, and a water-blocking pad 170. The locking pin 150 is fixedly mounted on the outer wall of the socket 110. One end of the locking rod 160 is formed with a locking hole that is compatible with the locking pin 150, and the other end is hinged to the sleeve 130 via a hinge. After the sleeve 130 is connected to the socket 110, the locking rod 160 can be connected to the locking pin 150 to limit the rotation of the sleeve 130 relative to the locking pin 150, further ensuring the sealing performance. The water-blocking pad 170 is arranged between the seal 140 and the sleeve 130 and is made of conductive rubber, which further improves the waterproof level and electromagnetic shielding level of the connection in the axial direction.
