Description

Technical Field

[0001] This utility model relates to the field of contactor technology, specifically to a circuit board mounting structure, a contactor auxiliary contact module, and a contactor. Background Technology

[0002] A prior art contactor auxiliary contact module has a circuit board connected to a micro switch. One or more pairs of limiting buckles are provided on the auxiliary module frame housing to fix the circuit board in the corresponding embedded groove of the auxiliary module frame housing. However, the existing limiting buckles are usually rigidly connected to the frame housing. During assembly, the circuit board can only be assembled by rigidly pressing the limiting buckles. The elastic deformation ability of the limiting buckles is not good, which leads to assembly difficulties and low efficiency of the circuit board and micro switch components on the frame housing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a circuit board mounting structure, which mainly solves the technical problems of difficult and inefficient assembly of circuit boards and micro-switch components on a frame housing.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A circuit board mounting structure includes a main frame and a circuit board. The main frame has an embedding groove, and the circuit board is adapted to be embedded in the embedding groove. The main frame also has at least one set of snap-fit ​​limiting mechanisms for pressing and positioning the circuit board in the embedding groove. The snap-fit ​​limiting mechanism includes at least one flexible connecting snap, which is configured to flexibly deform relative to the main frame when subjected to external force to avoid the embedding action of the circuit board.

[0006] Furthermore, the flexible connection buckle includes a flexible support portion and a buckle head connected to the flexible support portion, and the flexible support portion is configured to flexibly deform relative to the main frame when subjected to external force, so that the buckle head can be displaced to avoid the insertion action of the circuit board.

[0007] Furthermore, the deformation direction of the flexible support is configured to be perpendicular to the assembly direction of the circuit board and to bend and deform in a direction away from the outer edge of the circuit board.

[0008] Furthermore, the main frame is equipped with corresponding flexible support parts to provide space for deformation of the flexible support parts and avoidance gaps.

[0009] Furthermore, a wedge-shaped guide surface is formed on the buckle head.

[0010] Furthermore, the latching and limiting mechanism also includes rigid connecting latches set on the main frame, with the rigid connecting latches and flexible connecting latches distributed opposite each other on both sides of the circuit board.

[0011] Based on the same inventive concept, this utility model also provides a contactor auxiliary contact module, including a micro switch and the circuit board mounting structure described above. The micro switch mounting cavity is provided on the main frame and is connected to the embedding groove. The micro switch is soldered to the circuit board and embedded in the micro switch mounting cavity of the main frame. The circuit board is adaptedly embedded and fixed in the embedding groove of the main frame.

[0012] Based on the same inventive concept, this utility model also provides a contactor, including the circuit board mounting structure or contactor auxiliary contact module described above.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] The circuit board mounting structure, contactor auxiliary contact module, and contactor described in this utility model include a latching and limiting mechanism for pressing and positioning the circuit board in the embedding groove of the main frame. This mechanism includes at least one flexible connecting latch. Compared to existing technical solutions that use only rigid connecting latches, the flexible support is configured to deform flexibly relative to the main frame when subjected to external force. This allows the circuit board to squeeze the latch head and exert a lateral squeezing force on the flexible support during assembly, thereby causing the flexible support to undergo corresponding elastic deformation. This allows the latch head to shift and avoid the insertion of the circuit board, effectively reducing the assembly difficulty of the circuit board in the embedding groove of the main frame and thus improving assembly efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0023] Please refer to the appendix. Figure 1 To be continued Figure 4 An embodiment of this utility model provides a circuit board mounting structure, including a main frame 1 and a circuit board 2. The main frame 1 is provided with an embedding groove 11, and the circuit board 2 is adapted to be embedded in the embedding groove 11. The main frame 1 is also provided with at least one set of snap-fit ​​limiting mechanisms 3 for pressing and positioning the circuit board 2 in the embedding groove 11. The snap-fit ​​limiting mechanism 3 includes at least one flexible connecting snap 31. The flexible connecting snap 31 is configured to be able to flexibly deform relative to the main frame 1 when subjected to external force, so as to avoid the embedding action of the circuit board 2.

[0024] Please refer to the appendix. Figure 1 To be continued Figure 4 In one preferred embodiment, the flexible connecting buckle 31 preferably includes a flexible support portion 311 and a buckle head 312 connected to the flexible support portion 311. The flexible support portion 311 is configured to flexibly deform relative to the main frame 1 when subjected to external force, so that the buckle head 312 can be displaced to avoid the insertion action of the circuit board 2. It is understood that in this embodiment, the snap-fit ​​limiting mechanism 3 for snapping and positioning the circuit board 2 in the embedding groove 11 of the main frame 1 includes at least one flexible connecting snap 31. Compared with the existing technical solution that uses all rigid connecting snaps, since the flexible support part 311 is configured to be able to deform flexibly relative to the main frame 1 when subjected to external force, the circuit board 2 can squeeze the snap head 312 and generate a lateral squeezing force on the flexible support part 311 during assembly, thereby causing the flexible support part 311 to generate corresponding elastic deformation, so that the snap head 312 can be displaced to avoid the embedding action of the circuit board 2, effectively reducing the assembly difficulty of the circuit board 2 in the embedding groove 11 of the main frame 1, and thus helping to improve assembly efficiency.

[0025] Please refer to the appendix. Figure 1 To be continued Figure 4In one preferred embodiment, the deformation direction of the flexible support 311 is configured to be perpendicular to the assembly direction of the circuit board 2 and to bend and deform in a direction away from the outer side of the circuit board 2. Furthermore, the main frame 1 is provided with a clearance 12 corresponding to the flexible support 311 to provide deformation space for the flexible support 311.

[0026] Please refer to the appendix. Figure 1 To be continued Figure 4 In one preferred embodiment, a wedge-shaped guide surface is formed on the snap-fit ​​head 312. In this way, on the one hand, it can guide the assembly of the circuit board 2. On the other hand, after the circuit board 2 presses against the wedge-shaped guide surface of the snap-fit ​​head 312, part of the pressing force will be transformed into a lateral thrust, which will act on the flexible support part 311 to cause it to deform accordingly. At the same time, it will drive the snap-fit ​​head 312 to move to make way for the circuit board 2 to be snapped into the mounting groove 11.

[0027] Please refer to the appendix. Figure 1 To be continued Figure 4 In one preferred embodiment, the latching mechanism 3 further includes a rigid connecting latch 32 disposed on the main frame 1. The rigid connecting latch 32 and the flexible connecting latch 31 are distributed opposite each other on both sides of the circuit board 2. In this embodiment, preferably, the latching mechanism 3 includes one flexible connecting latch 31 and one rigid connecting latch 32 (the rigid connecting latch 32 is a conventional latch structure). The flexible connecting latch 31 and the rigid connecting latch 32 are distributed opposite each other in the embedding groove 11 to form a set of latching mechanisms 3. However, those skilled in the art should understand that in other embodiments, other numbers of latch structures can also be provided on the main frame 1. For example, two or three or more rigid connecting latches 32 can be arranged on the same side of the embedding groove 11, while one or two or more flexible connecting latches 31 can be arranged on the other side of the embedding groove 11; or only one or two or more flexible connecting latches 31 can be provided on both sides of the embedding groove 11.
