Description

Technical Field

[0001] This utility model belongs to the technical field of cable connection devices, and in particular relates to a shielded cable connection structure for connecting shielded cables. Background Technology

[0002] The primary function of shielded cables is to protect against interference from external electromagnetic waves on signals transmitted within the cable. In fields such as electronic equipment, communication systems, and automated control systems, electromagnetic waves of various frequencies exist in the surrounding environment. If ordinary cables lack shielding, these electromagnetic waves may couple into the cable, causing signal distortion, bit errors, and other problems. The shielding layer of a shielded cable can guide the current induced by external electromagnetic waves to the ground or other suitable potential points, thereby protecting the integrity and accuracy of signals within the cable.

[0003] According to the published patent CN211859568U, a cable connection structure includes a main body. The front end of the main body has a first connection port. The inner surface of the first connection port is provided with a waterproof and anti-slip mechanism. The outer surface of the main body has a fixing anti-slip mechanism and a fastening valve. The inclusion of the fixing anti-slip mechanism and the waterproof and anti-slip mechanism improves the fixing performance and safety factor, offering better application prospects. However, it still has the following shortcomings:

[0004] The above-mentioned equipment is relatively simple to install. However, when it is subjected to external forces, the connectors may come apart, resulting in poor stability of the device. Furthermore, the above-mentioned equipment is not convenient to protect the cable connection during use. If the cable shakes violently during use, the cable connection may break. Therefore, we propose a shielded cable connection structure for connecting shielded cables. Utility Model Content

[0005] The purpose of this utility model is to provide a shielded cable connection structure for connecting shielded cables. Through the connection mechanism and the protection mechanism, it solves the problems of existing equipment, which has a simple installation method, may cause the connectors to detach when subjected to external forces, resulting in poor stability of the device. In addition, existing equipment is not convenient to protect the cable connection during use. If the cable shakes violently during use, the cable connection may break.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a shielded cable connection structure for connecting shielded cables, including several connecting frames and shielded wires. A sealing gasket is fixedly connected to the outer wall of the connecting frame, and a connecting mechanism is provided on the outer wall of the connecting frame.

[0008] The connecting mechanism includes several connecting plates. The outer walls of the connecting plates are fixedly connected to the outer wall of the connecting frame. Several rotating rod sleeves are rotatably connected to the inner walls of the connecting plates. A rotating rod is rotatably connected to the inner wall of the rotating rod sleeve. A fixing plate is fixedly connected to the outer wall of the rotating rod sleeve on the right side. Several springs are fixedly connected to the outer wall of the fixing plate. A positioning rod is fixedly connected to the outer wall of the spring. A positioning hole is opened on the inner wall of the rotating rod near the positioning rod. A positioning rod is slidably connected to the inner wall of the positioning hole. The outer wall of the positioning rod is fixedly connected to the inner wall of the fixing plate. A limit groove is opened on the inner wall of the rotating rod sleeve on the left side.

[0009] Furthermore, a second limiting groove is provided on the inner wall of the rotating rod sleeve on the right side. The inner wall of the limiting groove and the inner wall of the second limiting groove are rotatably connected to the outer wall of the rotating rod. A protective mechanism is provided on the inner wall of the connecting frame.

[0010] Furthermore, the protective mechanism includes several fixed seats, and the outer walls of the several fixed seats are fixedly connected to the inner wall of the connecting frame.

[0011] Furthermore, a rotating block is rotatably connected to the outer wall of several of the fixed seats, and a number of telescopic rods are fixedly connected to the outer wall of the rotating block.

[0012] Furthermore, a second rotating block is fixedly connected to the outer wall of the end of the telescopic rod away from the rotating block, and a second spring is fixedly connected to the outer wall of the end of the rotating block near the telescopic rod. The outer wall of the second spring is fixedly connected to the outer wall of the rotating block.

[0013] Furthermore, the outer wall of the rotating block two is rotatably connected to a mounting plate, and the outer wall of the mounting plate is fixedly connected to several slide rails.

[0014] Furthermore, a bidirectional threaded rod is rotatably connected to the inner wall of the upper slide rail, and a plurality of clamping plates are slidably connected to the inner wall of the fixed base. The inner wall of the clamping plate is threadedly connected to the outer wall of the bidirectional threaded rod, and the outer wall of the clamping plate is slidably connected to the outer wall of the shielded wire.

[0015] Furthermore, a sliding rod is fixedly connected to the inner wall of the lower slide rail, and the outer wall of the sliding rod is slidably connected to the inner walls of several clamping plates.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates springs on the positioning rods. When the equipment is in use, multiple positioning rods are pulled outwards simultaneously, compressing the springs. When the positioning rods are completely pulled out of the positioning holes, the rotating rod is rotated to a suitable angle to allow it to be completely pulled out of the limiting groove. As the rotating rod is pulled out, it pulls the left rotating rod sleeve out of the connecting plate. Then, the right rotating rod sleeve is pulled out of the connecting plate, allowing the connecting frame to be removed. This facilitates easy docking and installation of the connecting device, and the installation method is simple and convenient for users. Furthermore, after installation, it prevents rainwater from entering the connection points of the shielded cable, improving cable safety.

[0018] 2. This utility model incorporates a clamping plate within the slide rail. During operation, the movement of the shielded cable causes the clamping plate to move, which in turn moves the mounting plate. This movement of the mounting plate causes the rotating block two to move to different positions, thereby compressing the spring two and the telescopic rod, causing them to stretch or contract to varying degrees. The movement of the telescopic rod causes the rotating block to move, which in turn causes the fixed seat to move, resulting in the connecting frame shaking. The spring two, through its own elastic force, causes the rotating block two to return to its original position. This design effectively protects the shielded cable, preventing the connection from loosening due to external factors such as wind during use. This increases the device's robustness and makes it easier for users to install the connecting device onto the shielded cable.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a shielded cable connection structure for connecting shielded cables, including several connecting frames 1 and shielded wires 101. A sealing gasket 102 is fixedly connected to the outer wall of the connecting frame 1, and a connecting mechanism 2 is provided on the outer wall of the connecting frame 1. The sealing gasket 102 can be used to seal the connection between the connecting frames 1 to prevent rainwater from entering the connection of the connecting frames 1.

[0030] The connecting mechanism 2 includes several connecting plates 201. The outer walls of the connecting plates 201 are fixedly connected to the outer wall of the connecting frame 1. Several rotating rod sleeves 202 are rotatably connected to the inner walls of the connecting plates 201. Rotating rods 203 are rotatably connected to the inner walls of the rotating rod sleeves 202. The connecting plates 201 facilitate quick connection between multiple connecting frames 1 by the user. A fixing plate 204 is fixedly connected to the outer wall of the rotating rod sleeve 202 on the right side. Several springs 205 are fixedly connected to the outer wall of the fixing plate 204. A positioning rod 206 is fixedly connected to the outer wall of the springs 205. 05. This prevents the positioning rod 206 from being pulled out of the positioning hole 207 during the fixing of the rotating rod 203, which would cause the rotating rod 203 to loosen. The inner wall of the rotating rod 203 near the positioning rod 206 has a positioning hole 207. The positioning rod 206 is slidably connected to the inner wall of the positioning hole 207. The outer wall of the positioning rod 206 is fixedly connected to the inner wall of the fixing plate 204. A limiting groove 208 is provided on the inner wall of the rotating rod sleeve 202 on the left side. Since the limiting groove 208 is flat on the outside and round on the inside, when the rotating rod 203 is inserted into the limiting groove 208 and rotated to guide the angle, it can be fixed by the limiting groove 208.

[0031] A limiting groove 209 is provided on the inner wall of the rotating rod sleeve 202 on the right side. The inner walls of the limiting groove 208 and the limiting groove 209 are rotatably connected to the outer wall of the rotating rod 203. The inner wall of the connecting frame 1 is provided with a protective mechanism 3, which includes several fixed seats 301. The fixed seats 301 can limit the position of the rotating block 302, so that the rotating block 302 can only rotate on the fixed seats 301, and at the same time, it can prevent the rotating block 302 from falling. The outer walls of the fixed seats 301 are fixedly connected to the inner wall of the connecting frame 1. The rotating block 302 is rotatably connected to the outer walls of the fixed seats 301. Several telescopic rods 303 are fixedly connected to the outer walls of the rotating block 302. The outer wall of the telescopic rod 303 away from the rotating block 302 is fixedly connected to the rotating block 305. The telescopic rods 303 can limit the movement trajectory of the spring 304, preventing the spring 304 from breaking during the extension and retraction process.

[0032] A spring 304 is fixedly connected to the outer wall of the rotating block 305 near the telescopic rod 303. The outer wall of the spring 304 is fixedly connected to the outer wall of the rotating block 302. A mounting plate 306 is rotatably connected to the outer wall of the rotating block 305. Several slide rails 307 are fixedly connected to the outer wall of the mounting plate 306. The slide rails 307 can limit the position of the clamping plate 309, so that it can only slide within the slide rails 307, and at the same time prevent the clamping plate 309 from falling off. A bidirectional threaded rod 308 is rotatably connected to the inner wall of the upper slide rail 307. Several clamping plates 309 are slidably connected to the inner wall of the fixed seat 301. 9. The inner wall of the clamping plate 309 is threadedly connected to the outer wall of the bidirectional threaded rod 308. Since the threaded rod 308 presents two opposite thread grooves, when the threaded rod 308 rotates, it will simultaneously drive the clamping plate 309 to move in the opposite direction. The outer wall of the clamping plate 309 is slidably connected to the outer wall of the shielded wire 101. A slide rod 310 is fixedly connected to the inner wall of the lower slide rail 307. The outer wall of the slide rod 310 is slidably connected to the inner walls of several clamping plates 309. The slide rod 310 can limit the movement trajectory of the clamping plate 309, making the sliding process of the clamping plate 309 in the slide rail 307 more stable.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, the user first places the shielded wire 101 into different connecting brackets 1 and connects the copper wires and other components attached to the shielded wire 101. Then, the threaded rod 308 is rotated, causing the clamping plate 309 to slide within the slide rail 307, thereby fixing the shielded wire 101 onto the connecting bracket 1. The connecting bracket 1 is then aligned, and the rotating rod sleeve 202 is fixed within the connecting plate 201. When the connecting bracket 1 needs to be removed, multiple positioning rods 206 are pulled outwards simultaneously. The movement of the positioning rods 206 compresses the spring 205. When the positioning rods 206 are completely pulled out of the positioning holes 207, the rotating rod 203 is rotated to a suitable angle so that it can be completely pulled out of the limiting groove 209. When the rotating rod 203 is pulled out, the left rotating rod sleeve 202 is also pulled out of the connecting plate 201. Then, the right rotating rod sleeve 202 is pulled out of the connecting plate 201. The connecting frame 1 can be removed. When the shielded wire 101 is shaken by external factors such as wind, the movement of the shielded wire 101 will cause the clamping plate 309 to move as a whole, and the mounting plate 306 to move. The movement of the mounting plate 306 will cause the rotating block 305 to move to different positions, thereby squeezing the spring 304 and the telescopic rod 303, causing them to stretch or contract to different degrees. The movement of the telescopic rod 303 will cause the rotating block 302 to move, and the fixed seat 301 to move, thereby causing the connecting frame 1 to shake. The spring 304 will drive the rotating block 305 to reset through its own elastic force, thereby eliminating part of the shaking of the connecting frame 1 and the shielded wire 101. The interface between the shielded wire 101 and the clamping plate 309 will shake violently or even break, causing the connection of the shielded wire 101 in the connecting frame 1 to break, thereby protecting the connection of part of the shielded wire 101 in the connecting frame 1.
