Description

Technical Field

[0001] This disclosure relates to the technical field of electrical switch manufacturing, and in particular to a foolproof structure for multi-position narrow gap switches that suppresses mold tolerance defects. Background Technology

[0002] In modern home environments, wall switches are among the most frequently used electrical accessories. Multi-panel switches are widely used due to their neat appearance and space-saving design. These switches integrate multiple switch modules onto a single panel, and the spacing between each individual switch unit is a crucial technical indicator for acceptance, as its consistency directly affects the product's functional reliability and lifespan.

[0003] In current manufacturing processes, clearance deviations mainly originate from mold processing deviations, injection molding shrinkage deformation, and cumulative assembly errors. Multi-position integrated switches have a compact structure and small tolerance limits; minute deviations can be amplified and accumulate during multi-module assembly. Furthermore, the causes of these errors are complex and often interdependent, making them difficult to detect in actual production.

[0004] However, gap deviations can also cause product functional defects; if the local gap is too large, the internal bottom shell structure is easily exposed, affecting sealing and safety performance; if the gap is too small, adjacent switch rockers will rub against each other when operating, affecting the user experience, and may even cause one switch to drive multiple switches in a coordinated manner, interfering with independent operation functions. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a multi-position narrow gap switch foolproof structure that can prevent functional defects caused by gap deviation and suppress mold tolerance defects.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A multi-position narrow-gap switch anti-mistake structure for suppressing mold tolerance defects includes a base box and multiple switch rockers. Each switch rocker is connected to the top of a corresponding transition piece, and the bottom of each transition piece is connected to a corresponding spring piece inside the base box. The structure includes:

[0008] The bottom box includes a box body and a support. The box body has a receiving groove, and a face ring is formed along the periphery of the receiving groove. The support is installed in the receiving groove and has multiple mounting grooves. Each transition piece is installed in a corresponding mounting groove. The side wall of the mounting groove is provided with a mounting through hole and a set of limiting ribs. The mounting through hole is located in the middle of the side wall of the mounting groove and is used to pass through the rotating shaft of the transition piece so that the transition piece can rotate in the mounting groove. The set of limiting ribs includes at least one supporting rib. The supporting rib is located on both sides of the side wall of the mounting groove and is used to support the top of the transition piece.

[0009] Multiple switch rockers are sequentially placed over the opening of the bottom box. Each switch rocker has two ends that movably abut against the face ring. Each switch rocker has a snap-fit ​​rib group on the side facing the bottom box, and the snap-fit ​​rib group is used to connect with the bottom box.

[0010] In one embodiment, the limiting rib group includes two top supporting ribs, which are symmetrically arranged on the side wall of the mounting groove.

[0011] In one embodiment, the top supporting rib and the bracket are integrally formed.

[0012] In one embodiment, the limiting rib group further includes two opposing limiting protrusions located on both sides of the mounting through hole, the limiting protrusions being used to abut against the top of the corresponding transition member.

[0013] In one embodiment, a limiting groove is formed on the side wall of the switch rocker, and the limiting block is located in the limiting groove.

[0014] In one embodiment, the limiting protrusion and the bracket are integrally formed.

[0015] In one embodiment, the snap-fit ​​rib assembly includes a mating rib and a limiting protrusion. The mating rib is connected to the bracket and the transition piece respectively, and the two ends of the limiting protrusion abut against the two side walls of the mounting groove respectively.

[0016] In one embodiment, the mounting groove is provided with a mating groove, and the mating protrusion abuts against the bottom of the mating groove.

[0017] In one embodiment, the snap-fit ​​rib assembly and the switch rocker are integrally formed.

[0018] In one embodiment, the box body and the face ring are integrally formed.

[0019] Compared with the prior art, this disclosure has at least the following advantages:

[0020] 1. The aforementioned multi-position narrow gap switch anti-mistake structure for suppressing mold tolerance defects, by setting limit ribs on the bracket to constrain the transition piece, and by using the snap-fit ​​ribs of the switch rocker to constrain the switch rocker, suppresses the gap deviation caused by the cumulative tolerance of the mold, ensuring that the switch rocker always maintains the preset position, thereby stably achieving uniform control of the gap of the multi-position switch rocker, and effectively avoiding the phenomenon of excessively large, small or misaligned gaps.

[0021] 2. The top support ribs of the bracket's limiting rib assembly abut against the transition piece, further constraining it and preventing it from shifting during use. This, in turn, prevents the switch rocker connected to the transition piece from shifting, ensuring the switch rocker remains in the preset position and achieving uniform control of the rocker gap for multi-position switches. Simultaneously, it prevents the transition piece from moving around, improving the consistency and stability of the switch assembly and ensuring reliable switch operation.

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] Please see Figures 1 to 4The multi-position narrow-gap switch anti-mistake structure 10, which is an embodiment of the present invention for suppressing mold tolerance defects, includes a base box 100 and multiple switch rocker arms 200. Each switch rocker arm 200 is used to connect to the top of a corresponding transition piece (not shown), and the bottom of each transition piece is connected to a corresponding spring piece (not shown) inside the base box 100. The base box 100 includes a box body 110 and a support 120. The box body 110 has a receiving groove 1101, and a face ring 111 is formed along the periphery of the receiving groove 1101. The bracket 120 is installed in the receiving groove 1101. The bracket 120 has multiple mounting grooves 121. Each transition piece is installed in a corresponding mounting groove 121. The side wall of the mounting groove 121 is provided with a mounting through hole 122 and a limiting rib group 123. The mounting through hole 122 is located in the middle of the side wall of the mounting groove 121. The mounting through hole 122 is used to pass through the rotating shaft of the transition piece so that the transition piece can rotate in the mounting groove 121. The limiting rib group 123 includes at least one supporting rib 1231. The supporting rib 1231 is located in the side wall of the mounting groove 121 and is used to support the top of the transition piece. Multiple switch rockers 200 are sequentially placed over the opening of the bottom box 100. The two ends of each switch rocker 200 are respectively in contact with the face ring 111. Each switch rocker 200 has a snap-fit ​​rib group 210 on the side facing the bottom box 100. The snap-fit ​​rib group 210 is used to connect with the bottom box 100.

[0032] In this embodiment, the multi-position narrow-gap switch anti-mistake structure 10, which suppresses mold tolerance defects, uses a limiting rib group 123 on the bracket 120 to constrain the transition member. Simultaneously, the locking rib group 210 of the switch rocker 200 cooperates in constraining the switch rocker 200, suppressing gap deviations caused by accumulated mold tolerances. This ensures that the switch rocker 200 always maintains a preset position, thereby stably achieving uniform control of the gap between the multi-position switch rocker 200 and effectively avoiding excessively large, small, or misaligned gaps. Furthermore, the supporting ribs 1231 of the limiting rib group 123 of the bracket 120 abut against the transition member, further constraining the transition member and preventing it from shifting during use. This prevents the switch rocker 200 connected to the transition member from shifting, ensuring that the switch rocker 200 is always in the preset position, thus achieving uniform control of the gap between the multi-position switch rocker 200. At the same time, it prevents the transition member from moving around, improving the consistency and stability of the switch assembly and ensuring the reliability of the switch operation.

[0033] like Figure 4As shown, in one embodiment, a pressure-holding rib (not shown) is provided on the top of the transition member. The pressure-holding rib is correspondingly provided with a top-holding rib 1231, which is used to hold the pressure-holding rib. It can be understood that by cooperating with the pressure-holding rib and the top-holding rib 1231, the transition member is further constrained to prevent it from shifting, thereby avoiding misalignment or uneven gap of the switch rocker 200 during the switching process, and further constraining to ensure the gap of the switch rocker 200.

[0034] like Figure 2 As shown, in one embodiment, the limiting rib group 123 includes two supporting ribs 1231, which are symmetrically arranged on the sidewalls of the mounting groove 121. It can be understood that each mounting groove 121 has two supporting ribs 1231 on each of its two sidewalls, meaning each mounting groove 121 has four supporting ribs 1231. This avoids deflection of the transition piece due to single-point support, further preventing deflection of the transition piece and the switch rocker 200, thereby controlling the gap between the switch rocker 200. Simultaneously, by pressing the transition piece at four points on both sides, errors caused by the mold and assembly errors are reduced, thereby reducing the gap deviation between the switch rocker 200s.

[0035] like Figure 2 As shown, in one embodiment, the top supporting rib 1231 and the bracket 120 are integrally formed. By integrally forming the top supporting rib 1231 and the bracket 120, the positional stability of the top supporting rib 1231 during operation is ensured, preventing the transition component from shifting or falling off, thereby avoiding interference with the movement of the transition component. At the same time, the integrated structure can eliminate installation errors, improve the installation accuracy of the transition component, and further control the gap between the switch rocker plates 200.

[0036] like Figure 2 As shown, in one embodiment, the limiting rib group 123 further includes limiting protrusions 1232, which are located on both sides of the mounting through hole 122. The limiting protrusions 1232 are used to abut against the top of the corresponding transition member. It can be understood that the limiting protrusions 1214 protrude from the mounting through hole 122, constraining the rotation position of the transition member, preventing the transition member from moving, thereby avoiding the switch rocker 200 from shifting due to the shaking of the transition member, ensuring that the switch rocker 200 is always in the preset position, thereby stably achieving uniform gaps between the multi-position switch rockers 200.

[0037] like Figure 3As shown, in one embodiment, a limiting groove 220 is formed on the side wall of the switch rocker 200, and a limiting protrusion 1232 is located within the limiting groove 220. In this embodiment, a limiting groove 220 is formed on one side of the switch rocker 200 corresponding to the limiting protrusion of the bracket 120. The limiting groove 220 is located inside the limiting protrusion 1232 to prevent the switch rocker 200 from shifting and to ensure that the switch rocker 200 is located in a preset position, thereby stably achieving uniform gaps between multiple switch rockers 200.

[0038] like Figure 2 As shown, in one embodiment, the limiting protrusion 1232 and the bracket 120 are integrally formed. In this embodiment, the limiting protrusion 1232 and the bracket 120 are integrally formed, which improves the structural strength and prevents the limiting protrusion 1232 from shifting or even falling off, thereby avoiding interference with the movement of the transition component. At the same time, the integrated structure can eliminate installation errors, improve the installation accuracy of the transition component, and further control the gap between the switch rocker plates 200.

[0039] like Figure 3 As shown, in one embodiment, the snap-fit ​​rib assembly 210 includes snap-fit ​​ribs 211 and mating protrusions 212. The snap-fit ​​ribs 211 are connected to the bracket 120 and the transition member, respectively, and the two ends of the mating protrusions 212 abut against the two side walls of the mounting groove 121. It can be understood that the switch rocker 200 is snapped into the transition member or the housing 100 via the snap-fit ​​ribs 211, so that the switch rocker 200 rotates synchronously with the transition member. The mating protrusions 212 abut against both sides of the mounting groove 120, further constraining the switch rocker 200 and preventing it from shaking or shifting, thereby improving the consistency and stability of the gaps between multiple switch rockers 200.

[0040] Furthermore, such as Figure 2 As shown, in one embodiment, the sidewall of the mounting groove 120 is provided with a mating groove 124, and the end of the mating protrusion 212 abuts against the bottom of the mating groove 124. The mating groove 124 further constrains the mating protrusion 212, improving the connection stability of the switch rocker 200, preventing loosening of the fit due to vibration or external force, and ensuring the assembly accuracy and reliability of the overall structure.

[0041] like Figure 3 As shown, in one embodiment, the snap-fit ​​rib assembly 210 and the switch rocker 200 are integrally formed, which improves the overall structural strength of the switch rocker 200 and eliminates assembly errors. Simultaneously, it improves the installation accuracy of the switch rocker 200, thereby ensuring that multiple switch rockers 200 are accurately positioned in their initial positions and guaranteeing uniform initial gaps between each switch rocker 200.

[0042] like Figure 2As shown, in one embodiment, the housing 110 and the face ring 111 are integrally formed. By integrally forming the face ring 111 and the housing 110, misalignment and cumulative tolerances caused by separate assembly of the housing 110 and the face ring 111 are avoided. This ensures that each rocker arm 200 maintains consistent flatness and gap uniformity after installation, preventing misalignment or inconsistent gap widths. Simultaneously, it simplifies the switch assembly process and improves product consistency.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] 1. The aforementioned multi-position narrow gap switch anti-mistake structure for suppressing mold tolerance defects, by setting limit ribs on the bracket to constrain the transition piece, and by using the snap-fit ​​ribs of the switch rocker to constrain the switch rocker, suppresses the gap deviation caused by the cumulative tolerance of the mold, ensuring that the switch rocker always maintains the preset position, thereby stably achieving uniform control of the gap of the multi-position switch rocker, and effectively avoiding the phenomenon of excessively large, small or misaligned gaps.

[0045] 2. The top support ribs of the bracket's limiting rib assembly abut against the transition piece, further constraining it and preventing it from shifting during use. This, in turn, prevents the switch rocker connected to the transition piece from shifting, ensuring the switch rocker remains in the preset position and achieving uniform control of the rocker gap for multi-position switches. Simultaneously, it prevents the transition piece from moving around, improving the consistency and stability of the switch assembly and ensuring reliable switch operation.

[0046] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
