Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

As described above, the inventor has found in the study of the electronic device that the existing electronic device generally includes a circuit board accommodated in a conductive metal housing, the conductive metal housing being grounded, and the circuit board being directly in contact with the conductive metal housing, so that the circuit board can be grounded through the conductive metal housing. However, relative movement may occur between the circuit board and the conductive metal housing, e.g., the circuit board may be out of contact with the conductive metal housing, resulting in the circuit board breaking electrical connection with the conductive metal housing, resulting in a ground failure of the circuit board. In this case, static electricity of the circuit board cannot be removed through grounding, which reduces the safety of the circuit board and may also cause damage to the circuit board.

The utility model will be better explained by the following detailed description of the embodiments with reference to the drawings. References herein to terms such as "upper", "lower", "left" and "right" refer to the orientation of FIG. 1. Defining the position of the second bending plate 41 relative to the spring plate 4 as "up"; the position of the holding piece 3 with respect to the limiting plate 2 is defined as "right".

In order to solve the technical problems, an embodiment of the application provides a connecting structure, which comprises a supporting plate, wherein a limiting plate is formed by extending from the end surface of the supporting plate, and a clamping piece and a spring piece are formed by extending from the limiting plate. The supporting plate and the two limiting plates enclose a circuit board mounting groove, and the circuit board mounting groove is used for accommodating a part of a circuit board. The circuit board may be clamped by two clamping pieces symmetrically arranged with respect to the circuit board. In the state of clamping the circuit board, the spring piece stretches under the action of elasticity and is contacted with the conductive metal shell; the spring piece still has elastic deformation under the state that the spring piece is contacted with the conductive metal shell. The circuit board can be grounded through the conductive metal shell and the connecting structure serving as a conductor, and under the condition that relative motion is generated between the circuit board and the conductive metal shell, the spring piece can be contacted with the conductive metal shell under the action of elastic force, so that the electric connection disconnection probability between the circuit board and the conductive metal shell is reduced, the safety of the circuit board is improved, the damage probability of the circuit board is reduced, and the service life of the circuit board is prolonged.

As shown in fig. 1 to 3, a connection structure provided in an embodiment of the present application includes: a support plate 1; the limiting plates 2 are formed by extending from the end surfaces of the supporting plates 1, and the supporting plates 1 and the two limiting plates 2 enclose a circuit board mounting groove; clamping pieces 3 formed by extending from the end surface of the limiting plate 2, wherein two clamping pieces 3 symmetrically arranged relative to the circuit board 100 are used for clamping the circuit board 100; a spring piece 4 formed to extend from the limiting plate 2 for contact with a conductive metal housing accommodating the circuit board 100, the spring piece 4 having an elastic deformation when the spring piece 4 is in contact with the grounded conductive metal housing; the connection structure is an electric conductor.

The support plate 1 may be a long strip, and the limiting plate 2 may be formed by bending a part of the long strip in one direction. Two limiting plates 2 may be formed, and the two limiting plates 2 may form an included angle therebetween or may be substantially parallel. The support plate 1 and the two limiting plates 2 enclose a circuit board mounting groove, which may be in a shape of a "U" or a "C", and may be used to accommodate a portion of the circuit board 100 as shown in fig. 3, so as to limit the movement of the circuit board 100.

Furthermore, a clamping piece 3 and a spring piece 4 are formed to extend from the end face of the limiting plate 2; as shown in fig. 1, a plurality of spring pieces 4 may be provided on the same limiting plate 2, or as shown in fig. 2, a plurality of spring pieces 4 may be provided on one limiting plate 2, and a plurality of spring pieces 4 may be provided on the other limiting plate 2. The number of the clamping pieces 3 and the number of the spring pieces 4 can be increased or decreased according to actual needs, and the connection structure shown in fig. 1 or the connection structure shown in fig. 2 can be selected according to the space distribution condition in the conductive metal shell; further, the length of the supporting plate 1 can be increased or decreased according to the needs, and the device has the characteristic of flexible arrangement.

In an exemplary embodiment, the circuit board 100 may be a printed circuit board (PCB, printed Circuit Board) or a printed circuit board assembly (PCBA, printed Circuit Board Assembly). The conductive metal housing may be grounded in a known manner, and may be an iron housing, an aluminum housing, a copper housing, etc., or may be an alloy housing. The connection structure is an electrical conductor so that the circuit board 100 is grounded through the connection structure. The connection structure may be a unitary structure. One end of the spring piece 4 may be connected to the limiting plate 2, and the other end of the spring piece 4 may move relatively to the limiting plate 2, for example, the spring piece 4 moves in a direction away from the plane of the limiting plate 2 until contacting the conductive metal housing. Although the conductive metal shell limits the movement of the spring plate 4, the spring plate 4 has elastic deformation to reduce the probability of coming out of contact with the conductive metal shell by the elastic force. The probability of the spring plate 4 being out of contact with the conductive metal shell can also be reduced in the case of relative movement of the conductive metal shell and the spring plate 4. In addition, the clamping piece 3 may also have elastic force so as to clamp the circuit board 100 more firmly.

During use, the position of the clamping tab 3 may be changed, for example, to allow the clamping tab 3 to expand so that a portion of the circuit board 100 can enter and be retained by the circuit board mounting slot. Subsequently, the holding pieces 3 can be restored, and the circuit board 100 is held by the two holding pieces 3 symmetrical with respect to the circuit board 100, thereby restricting the relative movement of the circuit board 100 and the connection structure. Next, the spring plate 4 may be brought into contact with the conductive metal housing by the elastic force. Because the connection structure is an electrical conductor, the circuit board 100 can be grounded through the clamping piece 3, the limiting plate 2, the supporting plate 1, the spring piece 4 and the conductive metal shell, so that static electricity accumulation of the circuit board 100 can be reduced, and the safety of the circuit board 100 is improved. The elasticity of the spring piece 4 can improve the contact stability of the spring piece 4 and the conductive metal shell, so that the grounding stability of the circuit board 100 can be improved, the damage probability of the circuit board 100 is reduced, and the service life of the circuit board 100 is prolonged.

Further, the limiting plate 2 includes a bendable portion 21, and the spring piece 4 is formed by extending from an end surface of the bendable portion 21.

In the exemplary embodiment, the bendable portion 21 is equivalent to extending the length of the spring plate 4, and can accumulate more elastic force, so as to further improve the contact stability between the spring plate 4 and the conductive metal housing. Specifically, one end of the spring piece 4 may be connected to the bendable portion 21, and the other end of the spring piece 4 may be referred to as a free end; when the connection structure is not mounted in the conductive metal housing, the bendable portion 21 may not be elastically deformed, and the bendable portion 21 may have an arc-shaped cross section. When the bendable portion 21 moves towards the straightening trend, the bendable portion 21 can generate elastic deformation; in a state where the connection structure is mounted in the conductive metal housing, the elastic deformation of the bendable portion 21 is superimposed with the elastic deformation of the spring piece 4, thereby increasing the reliability and the tightness of the contact between the spring piece 4 and the conductive metal housing.

Further, a gap 11 is formed between two adjacent holding pieces 3 on the same side of the circuit board 100.

In the exemplary embodiment, by providing the gap 11, the holding pieces 3 can be more easily operated, for example, by moving the opposite two holding pieces 3 away from each other in order to mount the connection structure to the circuit board 100 or to detach the connection structure from the circuit board 100. The gap 11 provides for ease of installation and removal of the connection structure.

Further, the end face of the grip piece 3 is formed with a first bending plate 31.

In an exemplary embodiment, the first bending plate 31 may be an arc-shaped first bending plate 31, and the center of the arc-shaped first bending plate 31 is located at a side of the first bending plate 31 away from the circuit board 100. Friction and collision between the clip 3 and the circuit board 100 during the process of mounting and dismounting the connection structure can be reduced by the first bending plate 31, and damage probability of the circuit board 100 is reduced.

Further, a spring piece 4 is provided between two adjacent holding pieces 3 on the same side of the circuit board 100.

In the exemplary embodiment, by disposing the spring piece 4 between the two holding pieces 3, the stress of the connection structure can be made relatively uniform, further improving the stability of the connection between the connection structure, the circuit board 100, and the conductive metal housing.

Further, the end face of the spring piece 4 is formed with a second bending plate 41.

In an exemplary embodiment, the second bending plate 41 may be an arc-shaped second bending plate 41, and a center of an arc surface of the second bending plate 41 is located at a side of the second bending plate 41 close to the circuit board 100. Friction and collision between the spring piece 4 and the conductive metal shell during the process of installing and dismantling the connecting structure can be reduced through the second bending plate 41, and damage probability of the conductive metal shell is reduced.

Further, the two spring pieces 4 are symmetrically arranged with respect to the circuit board 100.

In the exemplary embodiment, by the two spring pieces 4 symmetrically disposed with respect to the circuit board 100, the connection structure can be relatively uniformly subjected to the external force from the conductive metal housing, and the firmness of connection is improved.

Further, the extension length of the spring piece 4 with respect to the support plate 1 is larger than the extension length of the holding piece 3 with respect to the support plate 1.

In the exemplary embodiment, by providing the spring piece 4 longer in extension than the clip 3, it is possible to facilitate distinguishing the clip 3 from the spring piece 4, and the spring piece 4 is more extensible, improving the practicality of the connection structure.

Further, the connection structure is an integral stamping structure.

In an exemplary embodiment, by providing the connection structure of the integrated punching structure, the operations of welding and mounting bolts during the manufacturing process can be reduced, providing convenience for the installation of the connection structure.
