DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] In the description of this application, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0051] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0052] like Figure 1 As shown, the main difference between the traditional switch and the switch in this application is that the conductive connection plate 1 of the traditional switch does not have a bending setting relative to the conductive foot 2, so its production and assembly are difficult and not conducive to installation. In addition, the plug 3 of the traditional switch cannot prevent the migration of metal conductors, which can easily cause circuit mis-conduction.

[0053] like Figures 2-4As shown, the embodiment of the present application provides a switch, which comprises a base 100, a cover plate 200, a button 300, a spring 310 and a power supply part 400 arranged partially in the base 100, the power supply part 400 comprises a tab 410, a conductive pin 420 for connecting an external circuit and a conductive connecting plate 430 for internal circuit communication, the surface of the conductive connecting plate 430 has a metal conductor layer, the tab 410 is provided with a conductive part for the migration and attachment of the metal conductor layer at the position between two adjacent conductive connecting plates 430, because part of the electrical devices are used in a humid environment, the metal conductor layer will migrate in this environment, therefore, the conductive part is provided on the tab 410, the metal conductor layer will migrate into the conductive part and is not easy to attach to the surface of another conductive connecting plate 430, so that the internal circuit is still powered on without opening the switch, which effectively avoids the misconnection of the circuit, the misoperation of the electrical device and the alarm and the like.

[0054] The base 100 and the cover plate 200 are connected to form a chamber for packaging the power supply part 400; the tab 410 and the base 100 can be a split structure or an integral molding structure; the tab 410 is provided with at least two conductive connecting plates 430, the conductive connecting plates 430 on the tab 410 are arranged in a vertical direction to the top surface of the cover plate 200, and the surface of each conductive connecting plate 430 has a metal conductor layer; the tab 410 is provided with a conductive part at the position between the two adjacent conductive connecting plates 430, and the metal conductor layer can migrate and attach in the conductive part in the case of high environmental humidity.

[0055] It should be noted that the metal conductor layer will migrate in the case of high environmental humidity, for example, the environmental humidity is 85%-95%, and the environmental temperature can be 0℃-120℃.

[0056] The metal conductor layer can be selected from a silver ion plating layer, a gold ion plating layer, a tin ion plating layer, a copper layer or a stainless steel layer. The silver ion plating layer, the gold ion plating layer and the tin ion plating layer are all electroplating layers formed on the surface of the conductive connecting plate 430 by electroplating process, and the silver ion plating layer, the gold ion plating layer and the tin ion plating layer will migrate in the case of high humidity environment; the copper layer and the stainless steel layer are all base materials of the conductive connecting plate 430, and the copper layer or the stainless steel layer on the surface of the conductive connecting plate 430 will form an oxide layer in the case of high humidity environment, and the oxide layer will migrate and diffuse.

[0057] When the switch is in a high humidity environment, the metal conductor layer on the surface of the conductive connecting plate 430 migrates, at this time, the metal conductor layer on the surface of the upper conductive connecting plate 430 migrates into the conductive part, and is not easy to migrate to the surface of the lower conductive connecting plate 430, so that the adjacent two conductive connecting plates 430 are not easy to be conductive.

[0058] The insert piece 410 comprises a large surface 413 and a side surface 414 connected to each other and perpendicular to each other. In some embodiments, the conducting part is a through hole 411, which is perpendicular to the large surface 413 and has a shape of a straight line, a Z letter or an L letter in a cross section parallel to the large surface 413.

[0059] As shown in FIG. 4a, when the through hole 411 has a shape of a straight line, the metal conductor layer on the surface of the upper conductive connecting plate 430 migrates horizontally along the inner top wall of the through hole 411, so that the upper conductive connecting plate 430 is not easily connected to the lower conductive connecting plate 430. Figure 5 As shown in FIG. 4b, when the through hole 411 has a shape of a Z letter, both ends of the through hole 411 are misaligned with the lower conductive connecting plate 430, and the metal conductor layer on the surface of the upper conductive connecting plate 430 migrates towards both ends of the through hole 411, so that the upper conductive connecting plate 430 is not easily connected to the lower conductive connecting plate 430. Figure 6 As shown in FIG. 4c, when the through hole 411 has a shape of an L letter, the through hole 411 comprises a first through hole segment extending in a direction perpendicular to the cover plate 200 and a second through hole segment extending in a direction parallel to the cover plate 200. The first through hole segment of the through hole 411 extends towards the inner bottom wall of the base 100 and is misaligned with the lower conductive connecting plate 430. The metal conductor layer on the surface of the upper conductive connecting plate 430 migrates towards the first through hole segment of the through hole 411, so that the upper conductive connecting plate 430 is not easily connected to the lower conductive connecting plate 430. Figure 7

[0060] The electrically conductive part 400 comprises at least two conductive pins 420, and each conductive pin 420 corresponds to a conductive connecting plate 430. The conductive pin 420 and the corresponding conductive connecting plate 430 are in an integrated structure, and the insert piece 410 is injection molded with the conductive pin 420 and the conductive connecting plate 430 in the integrated structure.

[0061] In the case where the conducting part is the through hole 411, the conductive connecting plate 430 is bent relative to the conductive pin 420, and the conductive connecting plate 430 is perpendicular to the large surface 413. The conductive pin 420 extends out of the bottom of the base 100 and is used to connect an external circuit. The end of the conductive connecting plate 430 bent relative to the conductive pin 420 is arranged towards the key 300, i.e., the bending direction is towards the inside of the cavity, which facilitates processing and installation and reduces the assembly cost of the switch.

[0062] In some embodiments, the insert piece 410 is provided with two conductive connecting plates 430, and the two conductive connecting plates 430 are respectively arranged on the upper and lower sides of the through hole 411. The two conductive connecting plates 430 are respectively in an integrated structure with the corresponding two conductive pins 420.

[0063] As shown in FIG. 4a, when the through hole 411 has a shape of a straight line, the metal conductor layer on the surface of the upper conductive connecting plate 430 migrates horizontally along the inner top wall of the through hole 411, so that the upper conductive connecting plate 430 is not easily connected to the lower conductive connecting plate 430. Figure 8 ​As shown, for the electrically-conductive pin 420 and the electrically-conductive connecting plate 430 in an integrated structure, the electrically-conductive pin 420 comprises a first electrically-conductive section 421 and a second electrically-conductive section 422, the electrically-conductive connecting plate 430, the first electrically-conductive section 421 and the second electrically-conductive section 422 are sequentially connected and integrally formed, the electrically-conductive connecting plate 430, the first electrically-conductive section 421 and the second electrically-conductive section 422 are perpendicular to each other, the first electrically-conductive section 421 extends in a direction parallel to the cover plate 200, and the second electrically-conductive section 422 extends along the length direction of the spring 310 and extends out of the base 100, wherein the length of the first electrically-conductive section 421 is related to the position where the second electrically-conductive section 422 extends out of the base 100, if the horizontal distance between the position where the second electrically-conductive section 422 extends out of the base 100 and the electrically-conductive connecting plate 430 is closer, the length of the first electrically-conductive section 421 is shorter, and if the horizontal distance between the position where the second electrically-conductive section 422 extends out of the base 100 and the electrically-conductive connecting plate 430 is farther, the length of the first electrically-conductive section 421 is longer.

[0064] The electrically-conductive pin 420 and the electrically-conductive connecting plate 430 are integrally stamped from an electrically-conductive metal material, and the plug-in piece 410 can be assembled and fixed with the electrically-conductive pin 420 and the electrically-conductive connecting plate 430 in an integrated structure; preferably, the electrically-conductive pin 420 and the electrically-conductive connecting plate 430 are integrally stamped from a copper sheet, the plug-in piece 410 is made of insulating plastic material, and after the electrically-conductive pin 420 and the electrically-conductive connecting plate 430 are integrally formed, the plug-in piece 410 is injected into the electrically-conductive pin 420 and the electrically-conductive connecting plate 430 to form an integrated structure. The cover plate 200 is provided with a hole for the top of the key 300 to extend out, the key 300 can move relative to the cover plate 200 along the axial direction of the hole, and the top of the key 300 extends out of the cover plate 200 through the hole for pressing; one end of the spring 310 abuts against the inner bottom wall of the base 100, and the other end of the spring 310 extends into the accommodating groove 320 and abuts against the inner wall of the accommodating groove 320. Figure 9 The bottom of the key 300 is provided with an accommodating groove 320, and the other end of the spring 310 extends into the accommodating groove 320 and abuts against the inner wall of the accommodating groove 320; the key 300 is provided with an electrically-conductive clamping piece 500, and the electrically-conductive clamping piece 500 is in contact with two adjacent electrically-conductive connecting plates 430 to connect the circuit.

[0065] In other embodiments, the conductive part is a notch 412, the notch 412 is exposed on the side surface 414, in the case of the notch 412 as the conductive part, the electrically-conductive connecting plate 430 and the electrically-conductive pin 420 are in the same plane, the electrically-conductive connecting plate 430 is perpendicular to the side surface 414, and the electrically-conductive pin 420 extends out of the bottom of the base 100 for connecting an external circuit.

[0066] As shown in the drawings, Figure 10 in the case where the number of the electrically-conductive connecting plate 430 and the electrically-conductive pin 420 is three, the plug-in piece 410 is provided with a notch 412 between two adjacent electrically-conductive connecting plates 430.

[0067] As shown in the drawings, Figure 11As shown, the base 100 is provided with a limiting column 110, and the spring 310 is sleeved on the limiting column 110, and the limiting column 110 plays a role of limiting the spring 310, so that the spring 310 is not easy to be deviated during pressing the button 300.

[0068] In some embodiments, the number of the power supply parts 400 is two, and the conductive connecting plates 430 in the two power supply parts 400 are oppositely arranged.

[0069] The two adjacent conductive connecting plates 430 on the same power supply part 400 are connected by the conductive clamping piece 500, and the conductive connecting plates 430 are connected or disconnected by the conductive clamping piece 500 when the button 300 is pressed.

[0070] It should be noted that the single-side symmetric arrangement of the conductive connecting plates 430 in the two power supply parts 400 means that the conductive connecting plates 430 in the two power supply parts 400 are close to the same side of the plug-in piece 410 along the direction parallel to the cover plate 200, the middle symmetric arrangement of the conductive connecting plates 430 in the two power supply parts 400 means that the conductive connecting plates 430 in the two power supply parts 400 are located in the middle of the plug-in piece 410 along the direction parallel to the cover plate 200, and the oblique-angle symmetric arrangement of the conductive connecting plates 430 in the two power supply parts 400 means that the conductive connecting plates 430 in the two power supply parts 400 are misaligned along the direction parallel to the cover plate 200.

[0071] The base 100 and the cover plate 200 are fixed by snap-fit or ultrasonic welding, and the snap-fit is a conventional fitting mode in the art, and is preferably snap-fit.

[0072] As shown in the drawings, Figure 11 In the case of snap-fit between the base 100 and the cover plate 200, the two opposite surfaces of the base 100 are inwardly recessed to form recesses 120, and two guide portions 130 are oppositely arranged in the recesses 120, and a guide inclined surface is arranged on the guide portion 130; two plate bodies 210 are oppositely arranged on the cover plate 200, the two plate bodies 210 are positionally matched with the two recesses 120, and two snap-fit portions 211 are arranged on the bottom of the single plate body 210.

[0073] During assembling the base 100 and the cover plate 200, the two snap-fit portions 211 on the bottom of the plate body 210 are guided and deformed by the guide inclined surfaces on the two guide portions 130, and the snap-fit portions 211 are restored after passing through the corresponding guide portions 130 to be snap-fitted with the guide portions 130, so that the base 100 and the cover plate 200 are snap-fitted.

[0074] The base 100 is provided with two or more conductive pins 420 on at least one side. The number of conductive pins 420 on the two sides of the base 100 is determined according to different models. The two or more conductive pins 420 can be arranged on one side or on both sides. In the embodiment, the base 100 is provided with two or more conductive pins 420 on both sides.

[0075] The conductive clamping piece 500 is assembled on the key 300 or integrally formed with the key 300 by injection molding. The conductive clamping piece 500 moves synchronously with the key 300, thereby changing the contact and power supply between the conductive clamping piece 500 and different conductive connecting plates 430.

[0076] In the case where the conductive clamping piece 500 is assembled on the key 300, as shown in Figure 9 The key 300 is provided with a clamping groove 330 for accommodating and clamping the conductive clamping piece 500. In the case where the number of power supply members 400 is two, the key 300 is provided with two clamping grooves 330, which accommodate and clamp two conductive clamping pieces 500 respectively. One of the conductive clamping pieces 500 is used to connect the circuit when it contacts the conductive connecting plate 430 on one of the power supply members 400, and the other conductive clamping piece 500 is used to connect the circuit when it contacts the conductive connecting plate 430 on the other power supply member 400.

[0077] In some embodiments, as shown in Figure 12 The key 300 is provided with a soft cap 600. The soft cap 600 is made of rubber material.

[0078] The key 300 is provided with a soft cap 600. The soft cap 600 is made of rubber material.

[0079] In the case where the through hole 411 is the conductive connecting plate 430 perpendicular to the large surface 413, as shown in Figure 13 The conductive connecting plates 430 of the two power supply members 400 are close to the top of the plug-in piece 410. The conductive connecting plate 430 in one of the power supply members 400 is aligned with the conductive connecting plate 430 in the other power supply member 400 in the horizontal direction. The initial state of the switch is the power-on state. In the power-on state, the conductive clamping piece 500 contacts the two conductive connecting plates 430 at the same time. After the key 300 is pressed, the switch is powered off. In the power-off state, the conductive clamping piece 500 only contacts the lower conductive connecting plate 430.

[0080] As shown in Figure 14As shown, the conductive connecting plates 430 in the two energized components 400 are close to the bottom of the insert 410. The conductive connecting plates 430 in one energized component 400 and the conductive connecting plates 430 in the other energized component 400 are aligned horizontally. The initial state of the switch is the de-energized state. In the de-energized state, the conductive clip 500 only contacts the upper conductive connecting plate 430. When the button 300 is pressed, the power is turned on. In the powered state, the conductive clip 500 contacts both conductive connecting plates 430 at the same time.

[0081] like Figure 15 As shown, the conductive connecting plate 430 in one of the energizing components 400 is close to the top of the insert 410, and the conductive connecting plate 430 in the other energizing component 400 is close to the bottom of the insert 410. The conductive connecting plates 430 in the two energizing components 400 are vertically staggered. In the initial state of the switch, one side is energized and the other side is de-energized. In the state where one side is energized and the other side is de-energized, one conductive clip 500 is in contact with both conductive connecting plates 430 at the same time, and the other conductive clip 500 is in contact with only one conductive connecting plate 430. After the button 300 is pressed, the circuit that was originally energized is disconnected, and the circuit that was originally disconnected is energized. That is, it changes from one on and one off to one off and one on. That is, the conductive clip 500 that was originally in contact with both conductive connecting plates 430 at the same time becomes in contact with only one conductive connecting plate 430, and the conductive clip 500 that was originally in contact with only one conductive connecting plate 430 becomes in contact with both conductive connecting plates 430 at the same time.

[0082] When the conductive part is a slot 412 and the conductive connecting plate 430 is perpendicular to the side 414, such as Figure 16 As shown, taking the energized component 400 including two conductive connecting plates 430 as an example, the two conductive connecting plates 430 in the energized component 400 are close to the top of the insert 410. The initial state of the energized component 400 is the energized state. In the energized state, the conductive clip 500 is in contact with both conductive connecting plates 430 at the same time. When the button 300 is pressed, the power is cut off. In the de-energized state, the conductive clip 500 is only in contact with the lower conductive connecting plate 430.

[0083] like Figure 17 As shown, taking the energizing component 400, which includes two conductive connecting plates 430, as an example, the two conductive connecting plates 430 in the energizing component 400 are close to the bottom of the insert 410. The initial state of the energizing component 400 is the de-energized state. In the de-energized state, the conductive clip 500 only contacts the upper conductive connecting plate 430. When the button 300 is pressed, the energizing state is achieved. In the energized state, the conductive clip 500 contacts both conductive connecting plates 430 at the same time.

[0084] In summary, the embodiment of the application provides a switch, by setting the conducting part at the position where the plug 410 is adjacent to the two conductive connecting plates 430, the migration of the metal conductor layer is prevented, so that the false power-on of the circuit occurs, and the false alarm, false recording and other situations of the electrical device occur.

[0085] The above merely provides a specific implementation of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
