Description

Technical Field

[0001] This utility model relates to the field of push button switch technology, and specifically to a conductive sheet mounting structure for a push button switch. Background Technology

[0002] Currently, most power strips and sockets on the market are equipped with push-button switches to control the circuit on / off of the corresponding sockets. When the push-button switch is pressed in the initial position, the internal ratchet structure keeps the pressed position, and the internal conductive plates are electrically connected, thus turning on the power. When it is necessary to turn off the power, the push-button switch is pressed further in the pressed position, and the ratchet structure is lifted by the spring. At this time, the push-button switch returns to the initial position, and the conductive plates are disconnected from each other, thus turning off the power.

[0003] Based on the above, overload protection should also be installed on power strips and sockets to further reduce safety hazards. In the existing technology, bimetallic strips replace traditional stationary contacts and are used to connect with moving contacts. However, bimetallic strips are relatively large and occupy a lot of space inside the housing. In addition, push-button switches on the market usually also include light-emitting components. The light-emitting components need to be connected to conduct electricity synchronously when the button is powered on and synchronously turned off when the button is powered off. Therefore, additional stationary contacts are required for connecting parts. Since the light-emitting components are located inside the button, conductive springs are also needed to connect the light-emitting components, moving contacts, and stationary contacts in the button.

[0004] Since the number of conductive sheet assemblies is large and the parts are small, in the prior art, a pressing structure is usually set in the housing assembly to press and fix the conductive sheets. However, the conductive sheets are prone to shifting when they are placed into the housing assembly, which makes the assembly work difficult. Furthermore, due to the shifting of the conductive sheets, adjacent conductive sheets are prone to accidental contact. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conductive sheet mounting structure for a push-button switch.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a conductive sheet mounting structure for a push-button switch, comprising:

[0007] A housing assembly, a conductive sheet assembly disposed within the housing assembly, and a positioning assembly constraining the conductive sheet assembly within the housing assembly;

[0008] The housing assembly comprises at least two housing units that are spliced ​​together.

[0009] The conductive sheet assembly includes a plurality of conductive sheet units, at least one of the conductive sheet units having an elastic portion that receives an actuating force and actuates.

[0010] The housing assembly is provided with a positioning component, which includes at least one insulating seat unit spaced between two conductive sheet units. The insulating seat unit and the housing unit have a positioning support surface relative to the conductive sheet assembly, and the positioning support surface constrains the horizontal degree of freedom of the conductive sheet units and / or the insulating seat unit.

[0011] The positioning component spacers the conductive sheet assembly and cooperates with the housing assembly to restrict the vertical degrees of freedom of the positioning component and the conductive sheet assembly within the housing assembly.

[0012] Furthermore, the housing unit has an opening in the vertical direction, and another housing unit has a closed opening. The conductive sheet unit and the insulating base unit are stacked and fitted together in the vertical direction on the positioning support surface, and the housing unit abuts against the vertical ends of the insulating base unit and the conductive sheet unit.

[0013] Furthermore, the conductive sheet unit includes a movable contact sheet and a first stationary contact sheet, and the positioning component includes a first insulating seat. The first insulating seat separates the movable contact sheet and the first stationary contact sheet, and the first insulating seat is provided with a first groove for accommodating the movable contact sheet and a second groove for accommodating the first stationary contact sheet. The first groove and the second groove are staggered, and the opening directions of the first groove and the second groove are opposite to each other.

[0014] Furthermore, the conductive sheet unit includes a movable contact piece, the movable contact piece having a fixing part, the housing unit having a vertically extending first seat body, the first seat body having a first slot, one end of the fixing part having a first protrusion inserted into the first slot; the housing unit having a first pressing port for the fixing part to extend out, the insulating seat unit and the fixing part being pressed onto the first pressing port in sequence, and another housing unit being pressed onto the first pressing port, the first pressing port being disposed opposite to the first slot.

[0015] Furthermore, the other end of the fixing part is provided with a first extension, which extends perpendicularly to the first slot and abuts against the inner wall of the housing unit.

[0016] Furthermore, a second protrusion extends from the first base body, and a second groove that mates with the second protrusion is provided on the first insulating base; a third groove is provided on the first base body away from the second protrusion, and a corner portion that fits into the third groove is provided on the first insulating base; the first insulating base is supported on the first base body.

[0017] Furthermore, the second groove is provided with a third protrusion, and the first stationary contact piece is provided with a fourth groove that cooperates with the third protrusion; the housing unit is provided with a second pressure port that is opposite to the first pressure port, the end of the first stationary contact piece extends out of the second pressure port, and the two sides of the first stationary contact piece are also provided with a fifth groove that cooperates with the second pressure port, and another housing unit is inserted into the second pressure port and pressed against the first stationary contact piece.

[0018] Furthermore, the conductive sheet unit also includes a second stationary contact piece, and the insulating seat unit includes a second insulating seat. The second stationary contact piece is sandwiched between the second insulating seat and the housing unit. The housing unit is also provided with a third pressure port and a fourth pressure port that are disposed opposite to each other. The second stationary contact piece is placed in the third pressure port and the fourth pressure port. The second insulating seat is placed in and pressed into the third pressure port and the fourth pressure port.

[0019] Furthermore, the third and fourth pressure ports are provided with a first step on both sides, and the ends of the second insulating base are provided with a second step that matches the first step; the middle of the second stationary contact piece is provided with a sixth slot, and the housing unit is provided with a second seat body that is inserted into the sixth slot.

[0020] Furthermore, the housing unit includes an upper housing and a lower housing. The adjacent end faces of the upper housing and the lower housing are provided with opposing fasteners and fastener grooves. The upper housing and the lower housing are fastened to each other and pressed onto the conductive sheet assembly and the positioning assembly.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] This utility model uses an open housing unit to accommodate a conductive sheet assembly and a positioning assembly, and completes horizontal positioning through the positioning support surface between the three, thereby initially constraining the insulating seat unit and the conductive sheet unit within the housing assembly, while another housing unit acts as a clamping force.

[0023] During assembly, thanks to the vertically open housing unit and the horizontally configured positioning support surface, the conductive sheet unit and the insulating seat unit can be arranged vertically in sequence and maintain stability within the housing assembly. The assembly operation is simple and reliable. During assembly, the insulating seat unit separates each conductive sheet unit, so even if there is movement, it will not cause accidental contact. It is worth mentioning that since the positioning support surface is arranged horizontally, if the conductive sheet unit or the insulating seat unit has vertical movement or is not in the horizontal position, the subsequently stacked components will have a positional offset, indicating to the operator that there are errors in the previous steps and non-standard assembly.

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0058] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0059] like Figure 1-16 As shown, a conductive sheet mounting structure for a push-button switch includes:

[0060] The housing assembly 1, the conductive sheet assembly disposed within the housing assembly 1, and the positioning assembly constraining the conductive sheet assembly within the housing assembly 1;

[0061] The housing assembly 1 includes at least two housing units that are spliced ​​together.

[0062] The conductive sheet assembly includes multiple conductive sheet units, at least one of which has an elastic portion 3.1. The elastic portion 3.1 receives an actuating force and is actuated. The conductive sheet unit serves as a movable contact 3. The actuating force can be a pressing action to engage the conductive sheet units connected to the live wire, thereby conducting electricity.

[0063] The housing assembly 1 is provided with a positioning component, which is used to provide support and limit the conductive sheet unit and to separate multiple conductive sheet units from each other, thereby avoiding accidental contact between adjacent conductive sheet units;

[0064] The positioning assembly includes at least one insulating seat unit spaced between two conductive sheet units. The insulating seat unit and the housing unit have positioning support surfaces relative to the conductive sheet assembly. The positioning support surfaces are used to provide horizontal limitation for the conductive sheet units. At the same time, the insulating seat unit also achieves limitation within the housing assembly 1 through the positioning support surfaces, thereby constraining the horizontal degree of freedom of the conductive sheet units and / or the insulating seat unit.

[0065] The positioning component, in conjunction with the housing component 1, with the conductive sheet component spaced apart, thereby pressing the positioning component and the conductive sheet component onto the housing component 1 in the vertical direction, thus restricting the vertical degree of freedom of the positioning component and the conductive sheet component.

[0066] By combining the split housing unit with the modular conductive sheet assembly, the assembly process is decoupled. The conductive sheet unit and the insulating base unit adopt a vertical stacked layout, which allows the conductive sheet unit and the insulating base unit to be assembled one by one in the vertical direction, and ensures that each component is horizontally limited. This allows each component to be pre-assembled independently and then pressed together as a whole. Finally, the vertical clamping force is applied through the joint of the housing assembly 1 to complete the overall assembly, which significantly improves the assembly efficiency.

[0067] like Figure 5 and Figure 6 As shown, to further explain the housing assembly 1, one housing unit has an opening in the vertical direction, and another housing unit closes the opening. Specifically, the aforementioned housing units refer to the upper housing 1.1 and the lower housing 1.2. The upper housing 1.1 and the lower housing 1.2 are spliced ​​together. Preferably, the upper housing 1.1 and the lower housing 1.2 are connected by a snap-fit ​​connection, so that during the assembly process, it is only necessary to align the openings of the upper housing 1.1 and the lower housing 1.2 and press them together. During the assembly process, the upper housing 1.1 is inverted so that the opening of the upper housing 1.1 faces upward.

[0068] The conductive sheet unit and the insulating seat unit are stacked and fitted together in the vertical direction on the positioning support surface. That is, when each conductive sheet unit and the insulating seat unit are inserted into the housing unit, they are limited by the positioning support surface, and the housing unit abuts against the vertical ends of the insulating seat unit and the conductive sheet unit. In other words, the upper housing 1.1 and the upper housing 1.1 apply a relative force in the vertical direction to the insulating seat unit and the conductive sheet unit.

[0069] like Figure 11 As shown, in some embodiments, the conductive sheet unit includes a movable contact 3 and a first stationary contact 2, and the positioning component includes a first insulating seat 4. The first insulating seat 4 separates the movable contact 3 and the first stationary contact 2, thereby isolating them from accidental contact. The first insulating seat 4 is provided with a first groove 4.1 for accommodating the movable contact 3 and a second groove 4.2 for accommodating the first stationary contact 2. The first groove 4.1 and the second groove 4.2 are vertically offset, and the opening directions of the first groove 4.1 and the second groove 4.2 are opposite to each other. The first groove 4.1 and the second groove 4.2 are open in the width direction, and a stop wall is provided at the end of the first groove 4.1 and the second groove 4.2. Of course, the two stop walls are also opposite to each other in the width direction and are spaced apart in the vertical direction to limit the fixing part 3.2 of the first stationary contact 2 and the movable contact 3.

[0070] like Figure 7As shown, in a further embodiment where the movable contact 3 is positioned and supported in the housing unit, the movable contact 3 has a sheet-like fixing part 3.2, which is positioned on the first groove 4.1. The housing unit is provided with a vertically extending first seat 5, which has a first slot 5.1. One end of the fixing part 3.2 has a first protrusion 3.3 that fits into the first slot 5.1. Both the first slot 5.1 and the first protrusion 3.3 are arranged in the horizontal direction. At the same time, the fixing part 3.2 is supported on the first slot 5.1.

[0071] like Figure 6 and Figure 8 , Figure 10 As shown, the housing unit is provided with a first pressing port 1.3 for the extension of the fixing part 3.2. The first pressing port 1.3 is a through opening provided on the housing unit, and the first pressing port 1.3 is arranged in the same direction as the first slot 5.1. Preferably, the first pressing port 1.3 and the first slot 5.1 are arranged opposite each other at both ends of the fixing part 3.2, that is, the first pressing port 1.3 and the first slot 5.1 together constitute the positioning support surface for constraining the moving contact piece 3. The insulating seat unit and the fixing part 3.2 are pressed onto the first pressing port 1.3 in sequence, and another housing unit is pressed onto the first pressing port 1.3. During assembly, the first insulating seat 4 is pressed onto the fixing part 3.2 on the first slot 5.1 and the first pressing port 1.3, and then the first insulating seat 4 and the fixing part 3.2 of the moving contact piece 3 are pressed together by the cooperating force of the housing assembly 1.

[0072] Specifically, the first pressure port 1.3 is flush with the first groove port 5.1.

[0073] Specifically, the fixing part 3.2 of the movable contact piece 3 extends out of the first pressure port 1.3 and is provided with a second extension part 3.5 in the length direction. The second extension part 3.5 abuts against the outer wall surface of the upper housing 1.1.

[0074] Reference Figure 9 As shown, to further improve the positional reliability of the moving contact 3 in the housing unit, the other end of the fixing part 3.2 is provided with a first extension 3.4. The first extension 3.4 extends perpendicularly to the first slot 5.1, that is, the first extension 3.4 is arranged about the length of the housing unit and abuts against the inner wall of the housing unit.

[0075] Specifically, the first extension 3.4 abuts against the inner wall where the first pressure port 1.3 is located, thereby further limiting the fixing part 3.2 in the width direction.

[0076] from Figure 7As can be seen, as an option, an auxiliary seat 5.4 is also provided on one side of the first seat 5. The auxiliary seat 5.4 is spaced apart from the first seat 5 in the width direction and is supported on the fixing part 3.2 respectively. At least one auxiliary seat 5.4 is arranged adjacent to the first pressure port 1.3, thereby reliably supporting the length direction of the fixing part 3.2.

[0077] In this configuration, a positioning space is created between the adjacent auxiliary seat 5.4 and the first seat 5. The elastic part 3.1 of the movable contact 3 is placed in the positioning space, thereby limiting the movable contact 3 and facilitating the operator to assemble the movable contact 3.

[0078] like Figures 7 to 11 As shown, as a further embodiment of the horizontal limiting of the first insulation within the housing unit, a second protrusion 5.2 extends from the first base 5, and a second slot 4.3 that mates with the second protrusion 5.2 is provided on the first insulation base 4. The second protrusion 5.2 extends vertically from one side wall of the first slot 5.1.

[0079] The first base 5 is provided with a third groove 5.3 away from the second protrusion 5.2. The first insulating base 4 is provided with a corner portion 4.4 that is inserted into the third groove 5.3. The second groove 4.3 and the second protrusion 5.2 are arranged on both sides of the first base 5 in the width direction. The upper end face of the first groove 5.1 forms a support surface that abuts against the first insulating base 4. The third groove 5.3 is formed by a rib extending to one side of the first base 5, and the opening direction of the third groove 5.3 is vertically arranged. The corner portion 4.4 extends vertically and forms one side wall of the first groove 4.1.

[0080] The first insulating seat 4 is supported on the first seat body 5, and the end of the first insulating seat 4 is inserted into the first pressure port 1.3 and flush with the outer wall of the housing unit. At the same time, the first insulating seat 4 is pressed into the fixing part 3.2 in the first pressure port 1.3. The positioning support surface of the first insulating seat 4 is constructed by the first pressure port 1.3, the third groove 5.3 and the second protrusion 5.2, thereby effectively constraining the position of the first insulating seat 4 in the housing unit.

[0081] As a further embodiment of the first stationary contact 2, the first stationary contact 2 can be configured as a conventional sheet-like conductive sheet unit, which is used to engage with the movable contact 3 to conduct electricity or disconnect electricity. Alternatively, the first stationary contact 2 can be configured as a bimetallic sheet 9 with overload protection function.

[0082] Specifically, when the first stationary contact 2 is configured for overload protection, the first stationary contact 2 can be used as a whole as a bimetallic strip 9, or an additional bimetallic strip 9 can be provided and fixedly connected to the first stationary contact 2 to form a modular conductive sheet unit.

[0083] The following embodiments are all based on the premise that the first stationary contact 2 and the bimetallic strip 9 are fixed.

[0084] like Figure 8 and Figure 9 As shown, as a further embodiment of constraining the first stationary contact 2 within the housing unit, after the first insulating base 4 is placed into the upper housing 1.1, the second groove 4.2 on it is open upwards, and a third protrusion 4.5 is provided in the second groove 4.2. The first stationary contact 2 is provided with a fourth slot 2.1 that cooperates with the third protrusion 4.5. Preferably, the third protrusion 4.5 is provided on the stop edge 4.6 of the second groove 4.2 and is located near the first pressure port 1.3, and extends in the width direction to achieve a fully enclosed layout to prevent arc leakage.

[0085] The housing unit is provided with a second pressure port 1.4 opposite to the first pressure port 1.3. The end of the first stationary contact piece 2 extends out of the second pressure port 1.4, and the two sides of the first stationary contact piece 2 are also provided with a fifth groove 2.2 that cooperates with the second pressure port 1.4. Through the above improvements, the third protrusion 4.5 and the second pressure port 1.4 together form the positioning support surface of the first stationary contact piece 2, and the bimetallic strip 9 fixed on the first stationary contact piece 2 is horizontally limited. Another housing unit is inserted into the second pressure port 1.4 and pressed against the first stationary contact piece 2. During assembly, the lower housing 1.2 will abut against the first stationary contact piece 2 and fill and press against the second pressure port 1.4.

[0086] Further reference Figure 10 Specifically, since there are staggered step sections between the first stationary contact 2 and the bimetallic strip 9 due to their respective thicknesses, the second groove 4.2 is provided with a mating surface that is compatible with the first stationary contact 2 and the bimetallic strip 9, so that the bimetallic strip 9 and the first stationary contact 2 are reliably supported at their corresponding positions. The second groove 4.2 specifically includes a first mating surface 4.21 that supports the first stationary contact 2 and a second mating surface 4.22 that corresponds to the thickness of the bimetallic strip 9. The first mating surface 4.21 and the second mating surface 4.22 form a stepped structure, wherein the first mating surface 4.21 is flush with the second pressure port 1.4.

[0087] like Figure 12 As shown, in some other embodiments, the conductive sheet unit further includes a second stationary contact 6, and the insulating seat unit includes a second insulating seat 7. The second stationary contact 6 and the second insulating seat 7 are vertically opposite each other and are disposed away from the first insulating seat 4.

[0088] As an application of the second stationary contact 6, the moving contact 3 and the bimetallic strip 9 on the first stationary contact 2 are used to switch the power supply on and off. Specifically, this is achieved through a button assembly movably mounted on the housing assembly 1. A ratchet pressing structure 10 is located in the housing assembly 1 to achieve the pressing, holding, and releasing of the moving contact 3. An extension edge is provided on the bimetallic strip 9 for engaging with the moving contact 3. When an overload occurs, the bimetallic strip 9 will cause the extension edge to deform, forcing the extension edge to move away from the elastic part 3.1 of the moving contact 3. For this purpose, the housing assembly 10 will also be adjusted accordingly. A reset rod is inserted through the body component 1 to actuate the deformed part on the bimetallic strip 9 to reset the bimetallic strip 9. A light-emitting component is also provided on the push-button switch, which is used to emit light when the power is connected. The light-emitting component usually includes two conductive springs 13, one end of which engages with the elastic part 3.1 of the moving contact 3, and the other end engages with the second stationary contact 6, so as to control the on and off by the movement of the moving contact 3. The ratchet pressing structure 10, pressing component 11, light-emitting component and bimetallic strip 9 mentioned above are all conventional technical means in the art, and will not be described in detail here.

[0089] As a further embodiment of limiting the second stationary contact 6 in the housing unit, the second stationary contact 6 is sandwiched between the second insulating seat 7 and the housing unit; the housing unit is also provided with a third pressing port 1.5 and a fourth pressing port 1.6 arranged opposite to each other, both ends of the second stationary contact 6 are inserted into the third pressing port 1.5 and the fourth pressing port 1.6, and one end of the second stationary contact 6 extends out of the third pressing port 1.5, wherein the third pressing port 1.5 and the first pressing port 1.3 are located on the same side wall of the housing unit, and the second pressing port 1.4 and the fourth pressing port 1.6 are located on the other side wall of the housing unit; the second insulating seat 7 is inserted into and pressed tightly in the third pressing port 1.5 and the fourth pressing port 1.6.

[0090] Furthermore, the second stationary contact piece 6 has a sixth slot 6.1 in the middle, and the housing unit has a second seat 8 that is inserted into the sixth slot 6.1, so that the third pressure port 1.5, the fourth pressure port 1.6 and the second seat 8 together form the positioning support surface of the second stationary contact piece 6.

[0091] As a further embodiment of limiting the second insulating seat 7 within the housing unit, the third pressure port 1.5 and the fourth pressure port 1.6 are provided with a first step 1.61 on both sides. The first step 1.61 is provided in the length direction and is recessed into the inner side wall of the housing unit. The ends of the second insulating seat 7 are provided with a second step 7.1 that matches the first step 1.61. Through the cooperation of the first step 1.61 and the second step 7.1, the second insulating seat 7 is limited within the housing unit.

[0092] Preferably, the second insulating base 7 is also provided with a protruding edge that matches the contour of the second stationary contact piece 6. While accommodating the second stationary contact piece 6, the protruding edge also provides a horizontal limiting effect on the second insulating base 7 through the horizontally limiting second stationary contact piece 6. During assembly, the lower housing 1.2 presses against the second insulating base 7 and presses the second insulating base 7 and the second stationary contact piece 6 together in the third pressure port 1.5 and the fourth pressure port 1.6.

[0093] Optionally, the convex edge is mated to the second seat 8, thereby surrounding the periphery of the second stationary contact 6 to protect the second stationary contact 6.

[0094] The bimetallic strip 9 is located away from the end of the moving contact 3 and extends in the length direction to the second stationary contact 6, and is separated from the second stationary contact 6 by the second insulating seat 7.

[0095] Further reference Figure 14 As shown, specifically, the second insulating seat 7 has a first pressing block 7.2 that abuts against the third pressing port 1.5 and the fourth pressing port 1.6, and the second insulating seat 7 is supported by the first pressing block 7.2. The upper housing 1.1 is provided with a second pressing block 1.11 that abuts against the end face of the second stationary contact piece 6. The first pressing block 7.2, the second pressing block 1.11, the second insulating seat 7 and the second stationary contact piece 6 cooperate with each other and define the vertical position of the second insulating seat 7 and the second stationary contact piece 6 within the housing assembly 1.

[0096] Further reference Figure 15 and Figure 16 As shown, specifically, the lower housing 1.2 is provided with a third pressing block 1.21 corresponding to the first stationary contact piece 2. The third pressing block 1.21 and the first seat 5 together constrain the first insulating seat 4, the first stationary contact piece 2, and the bimetallic strip 9 in the vertical space within the housing assembly 1.

[0097] Further reference Figure 5 As shown, the end of the first insulating base 4 is provided with a fourth pressing block 4.7 extending into the first pressing port 1.3. The fourth pressing block 4.7 abuts against the fixing part 3.2 on the first pressing port 1.3, and the fourth pressing block 4.7 is flush with the outer end face of the first pressing port 1.3 and is abutted by the lower housing 1.2.

[0098] The first adapter surface 4.21 is preferably flush with the second pressure port 1.4 so that the first stationary contact piece 2 can extend out and the gap of the first stationary contact piece 2 at the second pressure port 1.4 is eliminated.

[0099] Further reference Figure 6The housing assembly 1 includes an upper housing 1.1 and a lower housing 1.2. The adjacent end faces of the upper housing 1.1 and the lower housing 1.2 are provided with opposing fasteners and fastening grooves. The upper housing 1.1 and the lower housing 1.2 are interlocked and pressed onto the conductive sheet assembly and the positioning assembly. The housing unit achieves rapid positioning and splicing through the interlocking structure of the fasteners / fastening grooves. The lower housing 1.2 includes first fasteners arranged at both ends in the length direction, and the upper housing 1.1 includes second fasteners arranged at both ends in the width direction, so that the upper housing 1.1 and the lower housing 1.2 are respectively subjected to vertically opposing tension to ensure the pressing effect of the housing assembly 1 on the internal components.

[0100] The second buckle is positioned between the upper housing 1.1 and the lower housing 1.2, and is located between the first stationary contact piece 2 and the second stationary contact piece 6, thereby improving the stability under force.

[0101] During the assembly of the conductive sheet assembly, the upper housing 1.1 is inverted with its opening facing upwards. Then, the moving contact 3, the first insulating seat 4, the first stationary contact 2, and the bimetallic strip 9 are sequentially placed on the first seat 5. The second stationary contact 6 and the second insulating strip are sequentially placed on the third pressing port 1.5 and the fourth pressing port 1.6. Then, the upper housing 1.1 is snapped on. The modular design supports the quick replacement of faulty parts. Only the snap-fit ​​structure of the housing assembly 1 needs to be separated to remove the specific conductive sheet unit and insulating seat unit. Moreover, the disassembly process will not affect the positioning accuracy of other components.

[0102] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
