[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0030] A shielding cover is a tool used to shield electronic signals. It is mainly used to shield external electromagnetic waves from interfering with internal integrated circuits or to shield electromagnetic waves generated internally to prevent electromagnetic waves from radiating outward. It is widely used in electronic products. During use, the shielding cover is usually fixed on the circuit board of the electronic product, thereby performing electromagnetic shielding on the integrated circuits in a specific area of ​​the circuit board.

[0031] See also Figure 1-2The existing shielding cover 1 is usually bent around to form a bent portion 2, and the edges of the bent portion 2 around are welded to the circuit board 3 to fix the shielding cover 1 on the circuit board 3. However, in the actual production or maintenance process, when the shielding cover needs to be disassembled, the engineering personnel need to desolder the shielding cover before disassembling it. During the subsequent assembly, the shielding cover needs to be re-welded on the circuit board, which is relatively cumbersome.

[0032] The embodiment of the present application designs a clamping device, and engineers can first fix several of the clamping devices on the circuit board by welding or the like, and then insert the bent portion of the shielding cover into the U-shaped opening grooves of the several clamping devices, so that the shielding cover can be fixed to the clamping device. When the shielding cover needs to be disassembled, the engineer only needs to apply external force to pull the bent portion of the shielding cover out of the U-shaped opening grooves of the several clamping devices, thereby making the process of disassembling and assembling the shielding cover easier.

[0033] In order to facilitate readers to understand the inventive concept of the present application, the specific structure of the clamping device is described below:

[0034] Please also read Figure 3-4 The clamping device 1000 includes a fixing plate 100 and a clamping member 200. The fixing plate 100 is used to be fixed on the external circuit board 3. The fixing plate 100 is preferably fixed on the circuit board 3 by welding. The clamping member 200 includes a first elastic arm 21 and a second elastic arm 22. One end of the first elastic arm 21 is connected to one side of the fixing plate 100, and one end of the second elastic arm 22 is connected to the other side of the fixing plate 100. The first elastic arm 21, the fixing plate 100, and the second elastic arm 22 together enclose a U-shaped opening groove 30 0, the U-shaped opening groove 300 is used to clamp the object to be clamped; wherein, when the object to be clamped is inserted into the U-shaped opening groove 300 and the object to be clamped abuts against the inner wall of the U-shaped opening groove 300, the first elastic arm 21 and the second elastic arm 22 will be elastically deformed and expand outward, so that the object to be clamped can be inserted into the bottom of the U-shaped opening groove 300 along the inner wall of the U-shaped opening groove 300, and at the same time, the elastically deformed first elastic arm 21 and the second elastic arm 22 will generate an extrusion force to squeeze the object to be clamped. In this way, the engineer can first fix several of the clamping devices 1000 on the circuit board 3 by welding or the like, and then insert the bent portion 2 of the shielding cover 1 into the U-shaped opening grooves 300 of several of the clamping devices 1000, so that the shielding cover 1 can be fixed to the clamping device 1000. When the shielding cover 1 needs to be disassembled, the engineer only needs to apply external force to pull the bent portion 2 of the shielding cover 1 out of the U-shaped opening grooves 300 of several of the clamping devices 1000, thereby making the process of disassembling and assembling the shielding cover 1 easier.

[0035] For further information, please also refer to Figure 5-6 , the first elastic arm 21 is concave toward the inside of the U-shaped opening groove 300 to form a first protrusion 23, and the second elastic arm 22 is concave toward the inside of the U-shaped opening groove 300 to form a second protrusion 24, so that when the object to be clamped is inserted into the U-shaped opening groove 300, the first protrusion 23 and the second protrusion 24 can squeeze the object to be clamped, and then clamp the object to be clamped. Since the first protrusion 23 and the second protrusion 24 both protrude from the inner wall of the U-shaped opening groove 300, the first protrusion 23 and the second protrusion 24 can generate a greater squeezing force when squeezing the object to be clamped, thereby better squeezing the object to be clamped. Among them, the first protrusion 23 is preferably integrally formed with the first elastic arm 21, and the second protrusion 24 is preferably integrally formed with the second elastic arm 22, so that the entire manufacturing process can be completed in a short time to improve production efficiency and reduce labor costs. At the same time, the need for multiple processes can be reduced, manufacturing time can be saved, and manufacturing costs can be further reduced. Of course, the first protrusion 23 can be welded to the first elastic arm 21, and the second protrusion 24 can be welded to the second elastic arm 22. The shapes of the first protrusion 23 and the second protrusion 24 are preferably hemispherical, so that the contact area between the first protrusion 23 and the second protrusion 24 and the object to be clamped can be smaller, thereby improving the clamping force; of course, the shapes of the first protrusion 23 and the second protrusion 24 can also be other shapes such as square and pyramid.

[0036] In some embodiments, the first protrusion 23 and the second protrusion 24 are staggered, so that the first protrusion 23 and the second protrusion 24 can provide clamping force from multiple directions or angles when clamping the object to be clamped, thereby enhancing the clamping stability of the object to be clamped. Compared with the fully aligned setting, the staggered setting can prevent the object to be clamped from slipping or rotating during the clamping process. In addition, due to the staggered setting, the clamping structure formed by the first protrusion 23 and the second protrusion 24 can adapt to objects to be clamped of different shapes and sizes, so that the clamping device 1000 can be used in a variety of application scenarios. The staggered setting can also make the clamping force more evenly distributed on the object to be clamped, avoiding damage or deformation of the object to be clamped due to excessive local pressure.

[0037] In some embodiments, the first protrusion 23 and the second protrusion 24 are close to the top of the U-shaped opening groove 300, so that the first protrusion 23 and the second protrusion 24 can contact the object to be clamped more quickly, thereby improving the clamping efficiency. At the same time, the position at the top is also more convenient for the operator to observe and adjust the clamping position. In some embodiments, along the bottom of the U-shaped opening groove 300 to the top, the first protrusion 23 and the second protrusion 24 are located on the same plane, which helps to simplify the overall structure, reduce unnecessary components and complexity, and thus reduce manufacturing costs.

[0038] It can be understood that the number of the first protrusions 23 and the second protrusions 24 can be multiple, and the multiple first protrusions 23 are evenly located inside the first elastic arm 21, and the multiple second protrusions 24 are evenly located inside the second elastic arm 22. The multiple first protrusions 23 and the second protrusions 24 squeeze the object to be clamped, so that the squeezing force of the multiple first protrusions 23 and the second protrusions 24 is evenly distributed on the surface of the object to be clamped.

[0039] Furthermore, the other end of the first elastic arm 21 is bent in a direction away from the U-shaped opening groove 300 to form a first guide portion 25, and the other end of the second elastic arm 22 is bent in a direction away from the U-shaped opening groove 300 to form a second guide portion 26. In this way, the object to be clamped can be inserted into the inner wall of the U-shaped opening groove 300 along the inner wall of the first guide portion 25 or the second guide portion 26, so that the object to be clamped is easier to insert into the U-shaped opening groove 300, thereby improving the efficiency of inserting the object to be clamped into the U-shaped opening groove 300.

[0040] Furthermore, the first elastic arm 21 and / or the second elastic arm 22 is provided with an opening 29 connected to the U-shaped opening groove 300, and the opening 29 is close to the bottom of the U-shaped opening groove 300. In this way, by adjusting the size and shape of the opening 29, the elasticity of the first elastic arm 21 and / or the second elastic arm 22 can be controlled, thereby adjusting the clamping force on the object to be clamped, so that the clamping device 1000 can adapt to objects to be clamped of different sizes, shapes and weights, and provide a more flexible and reliable clamping effect; in addition, the presence of the opening 29 reduces the material usage of the first elastic arm 21 and / or the second elastic arm 22, thereby reducing the weight of the entire clamping device 1000, which not only helps to reduce manufacturing costs, but also makes the clamping device 1000 lighter and easier to operate. Furthermore, a fixing portion 11 extends from the fixing plate 100 near the opening 29 and passes through the opening 29 . The fixing portion 11 is used to be fixed on the circuit board 3 . The fixing portion 11 can increase the fixing area of ​​the clamping device 1000 so that the clamping device 1000 is firmly fixed on the circuit board 3 .

[0041] In some embodiments, the fixing plate 100 is provided with a plurality of through holes 13. Thus, when the fixing plate 100 is welded to the circuit board 3, the through holes 13 can cause a fault effect to be produced on the welding surface between the fixing plate 100 and the circuit board 3, thereby improving the stress state of the welding surface, thereby enhancing the welding force of the welding surface, and thereby improving the stability between the fixing plate 100 and the circuit board 3.

[0042] For the above-mentioned clamping member 200, the clamping member 200 also includes a first connecting portion 27 and a second connecting portion 28, the first connecting portion 27 and the second connecting portion 28 are both curved, one end of the first connecting portion 27 is connected to one side of the fixing plate 100, the other end of the first connecting portion 27 is connected to one end of the first elastic arm 21, one end of the second connecting portion 28 is connected to the other side of the fixing plate 100, and the other end of the second connecting portion 28 is connected to one end of the second elastic arm 22. In this way, when the first elastic arm 21 and the second elastic arm 22 are elastically deformed by external force, the first connecting portion 27 and the second connecting portion 28 will also be elastically deformed, thereby alleviating the elastic deformation between the first elastic arm 21 and the second elastic arm 22 and the fixing plate 100, and reducing the risk of clamping failure caused by structural deformation or loosening.

[0043] In some embodiments, there are two clamping members 200, and the two clamping members 200 are respectively connected to the two ends of the fixing plate 100, and one clamping member 200 and the fixing plate 100 together enclose a U-shaped opening groove 300, and the two clamping members 200 and the fixing plate 100 correspond to the U-shaped opening groove 300 enclosed by the fixing plate 100, so that the two ends of the object to be clamped can be respectively inserted into the two U-shaped opening grooves 300, so that the clamping device 1000 can clamp the object to be clamped more stably.

[0044] In some embodiments, the middle of the fixing plate 100 extends to both sides to form a suction portion 12, and the suction portion 12 is used for adsorption by an external suction device, and the two clamping members 200 are respectively located on both sides of the suction portion 12. In a preferred embodiment, the two clamping members 200 are symmetrically arranged on both sides of the suction portion 12 to simplify the structure of the clamping device 1000. It can be understood that the shape of the suction portion 12 can be circular, square or polygonal.

[0045] In an embodiment of the utility model, the clamping device 1000 includes a fixed plate 100 and a clamping member 200, the clamping member 200 includes a first elastic arm 21 and a second elastic arm 22, one end of the first elastic arm 21 is connected to one side of the fixed plate 100, and one end of the second elastic arm 22 is connected to the other side of the fixed plate 100, the first elastic arm 21, the fixed plate 100 and the second elastic arm 22 jointly enclose a U-shaped opening groove 300, and the U-shaped opening groove 300 is used to clamp the object to be clamped; wherein, when the object to be clamped is inserted into the U-shaped opening groove 300 and the object to be clamped abuts against the inner wall of the U-shaped opening groove 300, the first elastic arm 21 and the second elastic arm 22 will undergo elastic deformation and expand outward, so that the object to be clamped can be inserted into the bottom of the U-shaped opening groove 300 along the inner wall of the U-shaped opening groove 300, and the elastically deformed first elastic arm 21 and the second elastic arm 22 will generate an extrusion force to squeeze the object to be clamped. In this way, the engineer can first fix several of the clamping devices 1000 on the circuit board 3 by welding or the like, and then insert the bent portion 2 of the shielding cover 1 into the U-shaped opening grooves 300 of several of the clamping devices 1000, so that the shielding cover 1 can be fixed to the clamping devices 1000. When the shielding cover 1 needs to be disassembled, the engineer only needs to apply external force to pull the bent portion 2 of the shielding cover 1 out of the U-shaped opening grooves 300 of several of the clamping devices 1000. Therefore, the clamping device 1000 can make the process of disassembling and assembling the shielding cover 1 easier.
