In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

With the advancement of society and the development of technology, the quality and quality requirements of control switches are also increasing.

In the existing control switch, for convenient disassembly and assembly, a middle frame and a cover plate in the control switch are connected in a buckling mode.

However, the connection by means of the snap-in manner can only realize the clamping positioning in the installation direction (such as the vertical direction in fig. 1), but cannot realize the clamping positioning of the middle frame and the cover plate in the direction perpendicular to the installation direction (such as the horizontal direction in fig. 1), so that the middle frame and the cover plate may loose in the direction perpendicular to the installation direction, and the quality of the control switch is affected.

In order to improve the quality of the control switch, the application provides a middle frame connecting structure which is used for the control switch.

Referring to fig. 1 to 4, the middle frame connecting structure includes a middle frame 100 and a cover plate 200, and the middle frame 100 and the cover plate 200 are connected by means of a buckle 300.

The middle frame 100 includes a frame wall for enclosing a mounting groove 110, and the mounting groove 110 is used for mounting a PCB board.

The cover plate 200 is provided with a limit groove 210, and the end position 130 of the frame wall is clamped in the limit groove 210.

Specifically, when the cover 200 is connected to the middle frame 100, the end portion 130 of the frame wall of the middle frame 100 is just clamped in the limiting groove 210.

In some embodiments, since the end position 130 of the frame wall has an annular structure, a limit groove 210 having an annular structure may be provided on the end surface of the cover 200 corresponding to the end position 130 of the frame wall, and when the cover 200 is connected to the middle frame 100 by the limit groove 210, the end position 130 of the frame wall can be completely retained in the limit groove 210, so as to ensure positioning accuracy.

Further, a first clamping block 140 is provided on the side wall of the end portion 130 of the frame wall, and the first clamping block 140 is used for contacting with the side wall of the limit groove 210.

Specifically, when the end portion 130 of the frame wall is clamped in the limiting groove 210, the first clamping block 140 contacts with the side wall of the limiting groove 210, so as to realize the clamping and positioning of the frame wall in the direction perpendicular to the installation direction of the middle frame 100 and the cover plate 200, and further realize the clamping and positioning of the middle frame 100 and the cover plate 200 in the direction perpendicular to the installation direction.

It can be seen that, in the middle frame connection structure of the present application, the limit groove 210 is disposed on the cover plate 200, so that the end portion 130 of the frame wall is clamped in the limit groove 210, and the first clamping block 140 is disposed on the side wall of the end portion 130 of the frame wall, so that when the end portion 130 of the frame wall is disposed in the limit groove 210, the first clamping block 140 can be mutually pressed and clamped with the side wall of the limit groove 210, so as to realize clamping and positioning of the middle frame 100 and the cover plate 200 in the direction perpendicular to the mounting direction, ensure the assembly quality of the middle frame 100 and the cover plate 200, prevent the loose condition between the middle frame 100 and the cover plate 200 due to connection in the manner of the buckle 300, and further ensure the quality of the control switch.

In addition, when the supporting block 160 supports the PCB, the second clamping block 170 provided on the supporting block 160 can clamp and position the PCB in a direction perpendicular to the installation direction of the PCB.

It will be appreciated that the support block 160 may be provided with a plurality of support blocks in order to ensure stability of supporting and clamping the PCB. For example, the supporting blocks 160 may be disposed in the mounting groove 110 according to the gear profile of the PCB, and the second clamping blocks 170 disposed on the plurality of supporting blocks 160 may be matched to form a limiting space perpendicular to the mounting direction of the PCB, where the limiting space may limit the PCB, so as to prevent the PCB from shaking in the mounting groove 110 and ensure the stability of the PCB.

Further, in order to avoid interference with the second clamping block 170 when the PCB board is mounted on the supporting block 160, a second inclined surface 180 may be provided at an end of the second clamping block 170.

In addition, the supporting block 160 can be arranged on the inner wall of the frame wall, the space of the middle frame 100 can be fully utilized in the mode, and the second clamping block 170 arranged on the supporting block 160 needs to be clamped with the PCB in an extrusion mode, so that the supporting block 160 is arranged on the inner wall of the frame wall, the supporting block 160 can be supported by the frame wall, and the supporting block 160 is prevented from being broken in the extrusion process of the second clamping block 170 and the PCB.
