Description

Technical Field

[0001] This utility model relates to the field of shielding shell technology, and in particular to a shielding shell for data transmission cables. Background Technology

[0002] The main function of the data cable shield is to shield high-frequency interference, reduce noise, and ensure signal clarity and stability.

[0003] Existing shielding shells typically consist of two thin metal sheets, which are welded together to the data cable connector to provide shielding protection. However, because the shielding shell is fixed by welding, it requires destructive removal during maintenance, making installation and removal cumbersome. Furthermore, since the shielding shell cannot restrain the wires connected to the core board, the wires can detach from the core board under external force during use, leading to data cable damage and poor performance. Therefore, we propose a new shielding shell for data transmission cables. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a shielding shell for data transmission cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shielding shell for a data transmission cable is designed, comprising a first shell and a second shell, wherein the adjacent surfaces of the first shell and the second shell are connected, and a receiving cavity is formed between them, and the core plate of the data transmission cable is located in the receiving cavity;

[0006] The first housing has receiving grooves on both the upper and lower sides, and the second housing has strip connecting plates installed on both the upper and lower sides. One end of the strip connecting plate extends into the receiving groove, and a strip limiting block is installed on the side of each strip connecting plate near the receiving groove. A limiting groove is opened on one side of the receiving groove. When the first housing and the second housing are in contact at their near ends, the strip limiting block extends into the limiting groove.

[0007] Two connecting shafts are symmetrically installed at one end of the first housing. Each connecting shaft has a strip-shaped fixing plate rotatably connected to its side via a fixing block. The two strip-shaped fixing plates are connected by a detachable structure. Pressure strips are installed at the near ends of the two strip-shaped fixing plates. Several arc-shaped grooves are opened at the near ends of the two pressure strips. When the near surfaces of the two pressure strips are in contact, the corresponding two arc-shaped grooves form an annular groove, through which the wires connected to the core plate pass.

[0008] Preferably, the bottom of the strip-shaped limiting block is inclined.

[0009] Preferably, the strip connecting plates are made of elastic metal material, and each strip connecting plate has a crease at the top end near the second housing.

[0010] Preferably, the detachable structure includes a connecting block that fixes one end of each strip fixing plate, one of the connecting blocks is provided with an adjusting screw that slides through the connecting block, and the bottom end of the adjusting screw also passes through another connecting block and engages with its thread.

[0011] Preferably, two L-shaped limiting blocks are installed at one end of the second housing near the strip fixing plate, and one end of the strip fixing plate extends into the corresponding L-shaped limiting block.

[0012] Preferably, two limiting guide rails are installed on the sides of the first and second housings that are far apart from each other, and the two sides of the core plate are located between the corresponding two limiting guide rails, with the edge of the core plate and the side of the limiting guide rails having a clearance fit.

[0013] Preferably, the first housing has opening slots on both sides, and one side of each opening slot is connected to a corresponding receiving slot.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] 1. The elasticity of the strip connecting plate can move the strip limiting block into the limiting groove, fixing the first housing and the second housing together, making it easy to install and remove.

[0016] 2. By adjusting the rotation of the bolts, the two strip fixing plates can be fixed together, thereby clamping and fixing the wires connected to the core plate, preventing the wires from falling off the core plate due to external forces during use, and improving the performance.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A shielding shell for a data transmission cable includes a first shell 1 and a second shell 2. The adjacent surfaces of the first shell 1 and the second shell 2 are connected, and a receiving cavity is formed between them. The core board of the data transmission cable is located in the receiving cavity. By combining the first shell 1 and the second shell 2 together, external electromagnetic waves can be isolated from the core board, so that the data transmission cable can be used normally.

[0024] like Figure 1 The first housing 1 has receiving grooves 5 on both the upper and lower sides, and the second housing 2 has strip connecting plates 7 installed on both the upper and lower sides. One end of the strip connecting plate 7 extends into the receiving groove 5, and the top of each strip connecting plate 7 is flush with the top of the receiving groove 5, so that the strip connecting plate 7 will not cause obstruction during use.

[0025] like Figure 1 and Figure 3 As shown, each strip connecting plate 7 is equipped with a strip limiting block 15 on the side near the receiving groove 5. A limiting groove 3 is opened on one side of the inside of the receiving groove 5. When the first housing 1 and the second housing 2 are in contact at their near ends, the strip limiting block 15 extends into the limiting groove 3. In actual use, the cooperation between the strip limiting block 15 and the limiting groove 3 can fix the first housing 1 and the second housing 2 together, which is convenient.

[0026] It should be noted that, as Figure 4 As shown, the strip connecting plate 7 is made of elastic metal material, and each strip connecting plate 7 has a crease 6 at the top near the second housing 2. The strip connecting plate 7 can be bent and deformed along the crease 6. Under the elastic force of the strip connecting plate 7, the strip limiting block 15 can be prevented from falling out of the limiting groove 3.

[0027] It should be noted that, as Figure 4 As shown, the bottom of the strip-shaped limiting block 15 is inclined. In use, under the action of the inclined bottom surface of the strip-shaped limiting block 15, when the first housing 1 and the second housing 2 are brought together, the strip-shaped limiting block 15 will be forced to move the strip-shaped connecting plate 7 upward, so that the bottom of the strip-shaped limiting block 15 moves to the end of the receiving groove 5. Then, when the first housing 1 and the second housing 2 are forced, the strip-shaped limiting block 15 moves to the limiting groove 3. Under the elastic force of the strip-shaped connecting plate 7, the strip-shaped limiting block 15 can move into the limiting groove 3 and be fixed. The fixing is convenient.

[0028] like Figure 1 and Figure 2 As shown, two connecting shafts 14 are symmetrically installed at one end of the first housing 1. Each connecting shaft 14 has a strip-shaped fixing plate 10 rotatably connected to its side via a fixing block 13. The two strip-shaped fixing plates 10 are connected by a detachable structure, which includes a connecting block 8 that fixes one end of each strip-shaped fixing plate 10. One of the connecting blocks 8 is provided with an adjusting screw 9, which slides through the connecting block 8. The bottom end of the adjusting screw 9 also passes through the other connecting block 8 and is threaded into it. In actual use, the two strip-shaped fixing plates 10 can be moved relative to each other by rotating the adjusting screw 9, making adjustment convenient.

[0029] like Figure 1 and Figure 2 As shown, pressure strips 11 are installed at the near ends of the two strip fixing plates 10. Several arc-shaped grooves 12 are opened at the near ends of the two pressure strips 11. When the near surfaces of the two pressure strips 11 are in contact, the corresponding two arc-shaped grooves 12 form an annular groove. The wires connected to the core plate pass through the annular groove. In actual use, by clamping the wires connected to the core plate in the arc-shaped grooves 12, the wires will not fall off the core plate when subjected to external forces, thus improving the performance.

[0030] Specifically, in use, the first housing 1 and the second housing 2 are placed on both sides of the core plate, and then the first housing 1 and the second housing 2 are moved relative to each other until their adjacent surfaces come into contact. At the same time, both sides of the core plate move into the corresponding limiting guide rails 16. During the movement of the first housing 1 and the second housing 2, the bottom inclined surface of the strip-shaped limiting block 15 is squeezed by the edge of the first housing 1, which will drive one end of the strip-shaped connecting plate 7 to move upward along the crease 6, so that the bottom of the strip-shaped limiting block 15 moves into the receiving groove 5. When the first housing 1 and the second housing 2 are in contact... When the near surfaces come into contact, the strip-shaped limiting block 15 moves to the corresponding limiting groove 3. Then, under the elastic force of the strip-shaped connecting plate 7, the strip-shaped limiting block 15 moves into the limiting groove 3, thus completing the installation. After that, the strip-shaped fixing plate 10 is rotated so that the pressure strips 11 on the two strip-shaped fixing plates 10 come into contact with each other, clamping and fixing the wire connected to the core plate in the arc-shaped groove 12. Then, the adjusting screw 9 is rotated to firmly fix the two strip-shaped fixing plates 10 together. When disassembling, the first housing 1 and the second housing 2 can be separated simply by removing the strip-shaped limiting block 15 from the limiting groove 3, making disassembly convenient.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, two L-shaped limiting blocks 17 are installed at one end of the second housing 2 near the strip fixing plate 10. One end of the strip fixing plate 10 extends into the corresponding L-shaped limiting block 17. The L-shaped limiting block 17 can limit the strip fixing plate 10, so that the strip fixing plate 10 remains stable during use and will not shake.

[0032] Furthermore, such as Figure 3 As shown, two limiting guide rails 16 are installed on the opposite sides of the interior of the first housing 1 and the second housing 2. The two sides of the core plate are located between the corresponding two limiting guide rails 16, and the edge of the core plate is fitted with the side of the limiting guide rail 16 with a clearance. The limiting guide rails 16 can limit the core plate, so that the core plate is connected to the first housing 1 and the second housing 2, and the core plate is prevented from shaking relative to the first housing 1 and the second housing 2 during use.

[0033] Furthermore, such as Figure 1 As shown, the first housing 1 has opening slots 4 on both sides, and one side of each opening slot 4 is connected to the corresponding receiving slot 5. During disassembly, the operator only needs to insert a screwdriver or other tool into the receiving slot 5 through the opening slot 4 to pry up the strip connecting plate 7, so that the strip limiting block 15 is disengaged from the limiting slot 3, and the first housing 1 and the second housing 2 can be separated, which is convenient for disassembly.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
