Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a split-type shielding ring. Background Art

[0002] A shielding magnetic ring is a ring structure used to reduce electromagnetic interference (EMI), usually made of ferrite materials (such as Mn-Zn). Its main function is to allow normal useful signals to pass smoothly while suppressing the passage of high-frequency interference signals. When electronic equipment is working, the surrounding electromagnetic fields may affect the normal operation of the equipment, and the shielding magnetic ring can offset these electromagnetic fields and reduce their impact on the equipment, thereby improving the stability and reliability of the equipment.

[0003] For example, the Chinese patent publication number CN106358433A discloses a spliced ​​shielding ring, which includes a semi-cylindrical first splicing part and a second splicing part matching the first splicing part, the first splicing part is provided with a mounting groove for accommodating the component to be installed, a first connecting groove for hingedly connecting the second splicing part is provided on one side edge of the rectangular cross section of the first splicing part, a second connecting groove for connecting the second splicing part is provided on the other side edge, and a first connecting protrusion and a second connecting protrusion matching the first connecting groove and the second connecting groove are respectively provided at corresponding positions of the second splicing part, and the second connecting groove and the second connecting protrusion are locked by a locking assembly. The present invention has at least the following advantages: simple structure, applicable to longer shielding wire assemblies, and wide application.

[0004] The existing technology has the following problems:

[0005] The prior art is composed of two different splicing parts. When one splicing part is damaged, it is necessary to find a component that is compatible with it for replacement, which makes it impossible to mass-produce the shielding ring during production, which is relatively inconvenient. Moreover, when the shielding ring is sleeved on the transmission line, there is a certain gap between the shielding ring and the transmission line, which is easy to retain dust and affect the use of the device. Utility Model Content

[0006] The utility model provides a split shielding ring to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A spliced ​​shielding ring comprises a shielding ring wall, wherein the upper and lower ends of the shielding ring wall are fixedly connected with connecting components, and the front and rear sides of the shielding ring wall are fixedly connected with clamping components, the connecting component comprises a connecting block 1, the bottom of the connecting block 1 is fixedly connected to the top of the shielding ring wall, and the clamping component comprises a clamping frame, and the opposite sides of the two clamping frames are fixedly connected to the front and rear sides of the shielding ring wall.

[0009] Preferably, a clamping block 1 is fixedly connected to the top of the inner wall of the connecting block 1, and a connecting block 2 is fixedly connected to the bottom of the shielding ring wall.

[0010] Preferably, a plurality of springs 1 are fixedly connected to the bottom of the inner wall of the connecting block 2, and a connecting plate 1 is fixedly connected to the top of the spring 1.

[0011] Preferably, a button is fixedly connected to one side of the top of the connecting plate 1, and the outer wall of the button is slidably connected to the top of one side of the inner wall of the connecting block 2. The other side of the top of the connecting plate 1 is fixedly connected to the card block 2, and the outer wall of the card block 2 is card-engaged with the outer wall of the card block 1.

[0012] Preferably, a fixing block is fixedly connected to one side in the middle of the inner wall of the clamping frame, and spring 2 is fixedly connected to both upper and lower ends of one side of the fixing block.

[0013] Preferably, one side of the two springs 2 is fixedly connected to a connecting plate 2, and one side of the connecting plate 2 is fixedly connected to a limiting arc plate.

[0014] Preferably, a clamping plate is fixedly connected to one side of the limiting arc plate, and an outer wall of the clamping plate is slidably connected to an inner wall of the other side of the clamping frame.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] 1. The utility model provides a spliced ​​shielding ring, which is moved downward by the force of the clamping block 2 and drives the connecting plate 1 to move downward and compress the spring 1. When the clamping block 2 moves to the inner side of the clamping block 1, the elastic action of the spring 1 drives the clamping block 2 to move upward, so that the clamping block 1 and the clamping block 2 on the two shielding ring walls are connected to each other to complete the fixation. When one of the shielding ring walls is damaged and needs to be replaced, the connecting plate 1 is driven to move downward and compress the spring 1 by pressing a button. The connecting plate 1 drives the clamping block 2 to move downward through the fixed connection, so that the clamping block 2 is retracted to the inside of the connecting block 2. At this time, the two shielding ring walls can be separated, and the damaged shielding ring wall can be replaced. By setting two identical shielding ring walls for splicing and connection, the time for finding components is reduced, so that the device can be mass-produced during production.

[0017] 2. The utility model provides a spliced ​​shielding ring. When two shielding ring walls approach each other, the clamping plate first contacts the transmission line, and is forced to move outward by the clamping plate. The clamping plate drives the limiting arc plate to move outward through the fixed connection, thereby driving the second connecting plate to move outward and compressing the second spring. The second spring drives the second connecting plate to move inward through the elastic action, thereby clamping the transmission line between the two shielding ring walls, so that the device and the transmission line are relatively fixed, and the transmission line can be better shielded.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-5 As shown, a spliced ​​shielding ring includes a shielding ring wall 1, the upper and lower ends of the shielding ring wall 1 are fixedly connected with a connecting component 2, the front and rear sides of the shielding ring wall 1 are fixedly connected with a clamping component 3, the connecting component 2 includes a connecting block 211, the bottom of the connecting block 211 is fixedly connected to the top of the shielding ring wall 1, the clamping component 3 includes a clamping frame 31, and the opposite sides of the two clamping frames 31 are fixedly connected to the front and rear sides of the shielding ring wall 1.

[0026] When using the device, first place the transmission line between the two shielding ring walls 1, move the two shielding ring walls 1 close to each other, connect the two shielding ring walls 1 through the action of the connecting component 2, and then clamp the transmission line through the action of the clamping component 3 to prevent the shielding ring wall 1 from sliding on the transmission line. The shielding ring wall 1 can shield the internal transmission line.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, a clamping block 212 is fixedly connected to the top of the inner wall of the connecting block 1 211, a connecting block 221 is fixedly connected to the bottom of the shielding ring wall 1, a plurality of springs 222 are fixedly connected to the bottom of the inner wall of the connecting block 221, a connecting plate 223 is fixedly connected to the top of the spring 222, a button 224 is fixedly connected to one side of the top of the connecting plate 1 223, an outer wall of the button 224 is slidably connected to the top of one side of the inner wall of the connecting block 221, a clamping block 225 is fixedly connected to the other side of the top of the connecting plate 1 223, and the outer wall of the clamping block 225 is clamped to the outer wall of the clamping block 1 212.

[0028] In specific implementation, the two shielding ring walls 1 are brought close to each other. When the block 1 212 and the block 2 225 contact each other, the block 2 225 is forced to move downward and drive the connecting plate 1 223 to move downward and compress the spring 1 222. When the block 225 moves to the inner side of the block 1 212, the elastic action of the spring 1 222 drives the block 2 225 to move upward, so that the block 1 212 and the block 2 25 on the two shielding ring walls 1 are mutually engaged to complete the fixation. When one of the shielding ring walls 1 is damaged and needs to be replaced, the button 224 is pressed to drive the connecting plate 1 223 to move downward and compress the spring 1 222. The connecting plate 1 223 drives the block 2 225 to move downward through the fixed connection, so that the block 225 shrinks to the inside of the connecting block 221. At this time, the two shielding ring walls 1 can be separated, and the damaged shielding ring wall 1 can be replaced. By setting two identical shielding ring walls 1 for splicing and connection, the time for finding components is reduced, so that the device can be mass-produced during production.

[0029] like Figure 5 As shown, in the present embodiment, a fixed block 32 is fixedly connected to one side in the middle of the inner wall of the clamping frame 31, and springs 2 33 are fixedly connected to the upper and lower ends of one side of the fixed block 32, and one side of the two springs 2 33 is fixedly connected to a connecting plate 2 34, and one side of the connecting plate 2 34 is fixedly connected to a limiting arc plate 35, and one side of the limiting arc plate 35 is fixedly connected to a clamping plate 36, and the outer wall of the clamping plate 36 is slidably connected to the inner wall on the other side of the clamping frame 31.

[0030] In specific implementation, when the two shielding ring walls 1 approach each other, the clamping plate 36 first contacts the transmission line, and is forced to move outward by the clamping plate 36. The clamping plate 36 drives the limiting arc plate 35 to move outward through the fixed connection, thereby driving the connecting plate 2 34 to move outward and compressing the spring 2 33. The spring 2 33 drives the connecting plate 2 34 to move inward through the elastic action, thereby clamping the transmission line between the two shielding ring walls 1, so that the device and the transmission line are relatively fixed, and the transmission line can be better shielded.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
