DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0049] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0050] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0051] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0052] like Figure 1 As shown, the main difference between the traditional switch and the switch in the present application is that the conductive connecting plate 1 of the traditional switch is not bent relative to the conductive foot 2, so its production and assembly are difficult and not conducive to installation, and the plug 3 of the traditional switch cannot prevent the migration of the metal conductor, which can easily cause the circuit to be misconnected.

[0053] like Figure 2-Figure 4As shown, an embodiment of the present application provides a switch, including a base 100, a cover plate 200, a button 300, a spring 310 and a power-carrying member 400 partially disposed in the base 100, the power-carrying member 400 including a plug-in sheet 410, a conductive foot 420 for connecting an external circuit and a conductive connecting plate 430 for connecting an internal circuit, the surface of the conductive connecting plate 430 having a metal conductor layer, the portion of the plug-in sheet 410 located between two adjacent conductive connecting plates 430 having a conducting portion for the migration and attachment of the metal conductor layer, because some electrical components need to be used in an environment with high humidity, the metal conductor layer will migrate in this environment, so a conducting portion is provided on the plug-in sheet 410, the metal conductor layer will migrate into the conducting portion, and is not easy to adhere to the surface of another conductive connecting plate 430, so it is not easy for the switch to be powered on when the switch is not turned on, thereby effectively avoiding situations such as circuit energization by mistake, electrical component malfunction and alarm.

[0054] The base 100 and the cover plate 200 are connected to form a chamber for encapsulating the power-carrying component 400; the plug-in sheet 410 and the base 100 can be a separate structure or an integrally formed structure; at least two conductive connecting plates 430 are arranged on the plug-in sheet 410, and the conductive connecting plates 430 on the plug-in sheet 410 are arranged at intervals in a direction perpendicular to the top surface of the cover plate 200, and the surface of each conductive connecting plate 430 has a metal conductor layer; the plug-in sheet 410 is provided with a conductive portion at a position between two adjacent conductive connecting plates 430, and the metal conductor layer can migrate and adhere to the conductive portion when the ambient humidity is high.

[0055] It should be noted that the metal conductor layer may migrate when the ambient humidity is high, for example, when the ambient humidity is 85%-95% and the ambient temperature is 0°C-120°C.

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

[0057] When the switch is in an environment with high humidity, 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 conductive connecting plate 430 located above migrates into the conductive part, but is not easy to migrate to the surface of the conductive connecting plate 430 below, making it difficult to conduct electricity between two adjacent conductive connecting plates 430.

[0058] The insert 410 includes a large surface 413 and a side surface 414 connected to each other, and the large surface 413 and the side surface 414 are perpendicular to each other. In some embodiments, the conductive portion is a through hole 411, which is opened perpendicular to the large surface 413 and is in a straight line, Z shape or L shape in a cross section parallel to the large surface 413.

[0059] like Figure 5 As shown, when the through hole 411 is in a straight line, the metal conductor layer on the surface of the conductive connecting plate 430 located above migrates laterally along the inner top wall of the through hole 411, making it difficult to conduct the conductive connecting plate 430 below; Figure 6 As shown, when the through hole 411 is in a Z-shape, both ends of the Z-shaped through hole 411 are misaligned with the conductive connecting plate 430 below, and the metal conductor layer on the surface of the conductive connecting plate 430 above migrates toward the two ends of the Z-shaped through hole 411, so that it is not easy to conduct the conductive connecting plate 430 below; Figure 7 As shown, when the through hole 411 is L-shaped, the through hole 411 includes a first through hole section extending in a direction perpendicular to the cover plate 200 and a second through hole section extending parallel to the cover plate 200. The first through hole section of the through hole 411 extends toward the inner bottom wall of the base 100 and is misaligned with the conductive connecting plate 430 below. The metal conductor layer on the surface of the conductive connecting plate 430 above migrates toward the first through hole section of the through hole 411, making it difficult to conduct the conductive connecting plate 430 below.

[0060] The current-carrying member 400 includes at least two conductive pins 420 , which correspond to conductive connecting plates 430 one by one. The conductive pins 420 and the corresponding conductive connecting plates 430 are an integral structure, and the insert 410 is injection molded with the conductive pins 420 and the conductive connecting plates 430 which are an integral structure.

[0061] In the case where the conductive portion is a through hole 411, the conductive connecting plate 430 is bent relative to the conductive foot 420, the conductive connecting plate 430 is perpendicular to the large surface 413, and the conductive foot 420 is passed through the bottom of the base 100 for connecting to an external circuit. The end of the conductive connecting plate 430 bent relative to the conductive foot 420 is arranged toward the button 300, that is, the bending direction is toward the inside of the chamber, which is convenient for processing and installation, and reduces the assembly cost of the switch.

[0062] In some embodiments, two conductive connecting plates 430 are disposed on the plug 410 . The two conductive connecting plates 430 are respectively located at the upper and lower sides of the through hole 411 . The two conductive connecting plates 430 are respectively integrated with the corresponding two conductive feet 420 .

[0063] like Figure 8As shown, for the conductive foot 420 and the conductive connecting plate 430 in an integrated structure, the conductive foot 420 includes a first conductive segment 421 and a second conductive segment 422. The conductive connecting plate 430, the first conductive segment 421 and the second conductive segment 422 are sequentially connected and integrally formed. The conductive connecting plate 430, the first conductive segment 421 and the second conductive segment 422 are perpendicular to each other. The first conductive segment 421 extends in a direction parallel to the cover plate 200, and the second conductive segment 422 extends along the length direction of the spring 310 and extends out of the base 100. The length of the first conductive segment 421 is related to the position where the second conductive segment 422 extends out of the base 100. If the horizontal distance between the position where the second conductive segment 422 extends out of the base 100 and the conductive connecting plate 430 is closer, the length of the first conductive segment 421 is shorter. If the horizontal distance between the position where the second conductive segment 422 extends out of the base 100 and the conductive connecting plate 430 is farther, the length of the first conductive segment 421 is longer.

[0064] The conductive foot 420 and the conductive connecting plate 430 are integrally stamped from a conductive metal material, and the insert 410 can also be assembled and fixed with the conductive foot 420 and the conductive connecting plate 430 in an integral structure; preferably, the conductive foot 420 and the conductive connecting plate 430 are integrally stamped from a copper sheet, and the insert 410 is made of an insulating plastic material. After the conductive foot 420 and the conductive connecting plate 430 are integrally formed, they are placed in an injection mold, and the insert 410, the conductive foot 420 and the conductive connecting plate 430 are injection molded into an integral structure. The cover plate 200 is provided with a hole for the top of the button 300 to extend out, and the button 300 can move relative to the cover plate 200 along the axial direction of the hole, and the top of the button 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, combined with the Fig. 9 A receiving groove 320 is provided at the bottom of the button 300, and the other end of the spring 310 extends into the receiving groove 320 and abuts against the inner wall of the receiving groove 320; a conductive clip 500 is provided on the button 300, and the conductive clip 500 connects the circuit when it contacts two adjacent conductive connecting plates 430 at the same time.

[0065] In other embodiments, the conductive portion is a notch 412, and the notch 412 is exposed on the side 414. When the conductive portion is the notch 412, the conductive connecting plate 430 and the conductive foot 420 are in the same plane, the conductive connecting plate 430 is perpendicular to the side 414, and the conductive foot 420 passes through the bottom of the base 100 for connecting to an external circuit.

[0066] For example, Fig.10 As shown, when the number of the conductive connecting plates 430 and the number of the conductive pins 420 are both three, the inserting piece 410 is provided with a notch 412 between two adjacent conductive connecting plates 430 .

[0067] like Fig.11As shown, a limiting column 110 is provided in the base 100 , and the spring 310 is sleeved on the limiting column 110 . The limiting column 110 serves to limit the spring 310 , so that the spring 310 is not easily deflected during the process of pressing the button 300 .

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

[0069] Two adjacent conductive connecting plates 430 on the same power supply member 400 are connected and energized via a conductive clip 500. When the key 300 is pressed, the conductive connecting plates 430 are contacted by the conductive clip 500 to switch the power on and off. The conductive connecting plates 430 in the two power supply members 400 are symmetrically arranged on one side, symmetrically arranged in the middle, or symmetrically arranged at an oblique angle.

[0070] It should be noted that the conductive connecting plates 430 in the two power-carrying parts 400 are unilaterally symmetrically arranged, which means that the conductive connecting plates 430 in the two power-carrying parts 400 are close to the same side of the plug-in piece 410 along the direction parallel to the cover plate 200; the conductive connecting plates 430 in the two power-carrying parts 400 are intermediately symmetrically arranged, which means that the conductive connecting plates 430 in the two power-carrying parts 400 are located in the middle of the plug-in piece 410 along the direction parallel to the cover plate 200; and the conductive connecting plates 430 in the two power-carrying parts 400 are obliquely symmetrically arranged, which means that the conductive connecting plates 430 in the two power-carrying parts 400 are staggered along the direction parallel to the cover plate 200.

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

[0072] like Fig.11 As shown, when the base 100 and the cover 200 are snap-fitted together, the two opposite surfaces of the base 100 are recessed inward to form a groove 120, and two guide portions 130 are oppositely arranged in the groove 120, and the guide portions 130 are provided with guide slopes; two sheets 210 are oppositely arranged on the cover 200, and the positions of the two sheets 210 match the two grooves 120, and two snap-fitting portions 211 are provided at the bottom of a single sheet 210.

[0073] During the process of assembling the base 100 and the cover plate 200, the two snap-fitting parts 211 at the bottom of the sheet 210 are deformed by the guiding inclined surfaces on the two guide parts 130. After passing through the corresponding guide parts 130, the snap-fitting parts 211 recover their deformation and snap-fit ​​with the guide parts 130, so that the base 100 and the cover plate 200 are snap-fitted together.

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

[0075] The conductive clip 500 is mounted on the button 300 or the conductive clip 500 and the button 300 are injection molded into an integral structure. The conductive clip 500 and the button 300 move synchronously, thereby changing the contact and power supply between the conductive clip 500 and different conductive connecting plates 430 .

[0076] When the conductive clip 500 is assembled on the key 300, as shown in FIG. Fig. 9 As shown, a slot 330 for accommodating and holding a conductive clip 500 is provided on the button 300. When the number of the power-carrying parts 400 is two, two slots 330 are provided on the button 300. The two slots 330 respectively accommodate and hold two conductive clips 500. One of the conductive clips 500 is used to connect the circuit when it contacts with a conductive connecting plate 430 on one of the power-carrying parts 400, and the other conductive clip 500 is used to connect the circuit when it contacts with a conductive connecting plate 430 on the other power-carrying part 400.

[0077] In some embodiments, Fig.12 As shown, a soft cap head 600 is arranged on the button 300. The soft cap head 600 is arranged as required and is made of rubber material.

[0078] The power-on mode of the button 300 is: powered on in the initial state, and powered off after being pressed; or powered off in the initial state, and powered on after being pressed; or the initial state is powered on the left side and powered off on the right side, and powered on the left side and powered off on the right side after being pressed.

[0079] In the case where the conductive portion is a through hole 411 and the conductive connecting plate 430 is perpendicular to the large surface 413, as shown in FIG. Fig.13 As shown, the conductive connecting plates 430 in the two power-carrying parts 400 are overall close to the top of the plug 410, and the conductive connecting plates 430 in one power-carrying part 400 are aligned with the conductive connecting plates 430 in the other power-carrying part 400 in the horizontal direction. The initial state of the switch is the power-on state. In the power-on state, the conductive clip 500 contacts the two conductive connecting plates 430 at the same time. The power is cut off after the button 300 is pressed. In the power-off state, the conductive clip 500 only contacts the conductive connecting plate 430 below.

[0080] like Fig.14As shown, the conductive connecting plates 430 in the two power-carrying parts 400 are generally close to the bottom of the plug 410, and the conductive connecting plates 430 in one power-carrying part 400 are aligned with the conductive connecting plates 430 in the other power-carrying part 400 in the horizontal direction. The initial state of the switch is the power-off state. In the power-off state, the conductive clip 500 only contacts the upper conductive connecting plate 430. After the button 300 is pressed, the power is turned on. In the power-on state, the conductive clip 500 contacts the two conductive connecting plates 430 at the same time.

[0081] like Fig.15 As shown, the conductive connecting plate 430 in one of the energizing members 400 is close to the top of the plug 410, and the conductive connecting plate 430 in the other energizing member 400 is close to the bottom of the plug 410. The conductive connecting plates 430 in the two energizing members 400 are vertically staggered. The initial state of the switch is that 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 of the conductive clips 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 of the conductive connecting plates 430. After the button 300 is pressed, the originally energized circuit is disconnected, and the originally disconnected circuit 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 changes to only contact with one conductive connecting plate 430, and the conductive clip 500 that was originally in contact with only one of the conductive connecting plates 430 changes to contact with both conductive connecting plates 430 at the same time.

[0082] In the case where the conductive portion is the notch 412 and the conductive connecting plate 430 is perpendicular to the side surface 414, as shown in FIG. Fig.16 As shown, taking the example of the power-carrying member 400 including two conductive connecting plates 430, the two conductive connecting plates 430 in the power-carrying member 400 are overall close to the top of the plug 410, and the initial state of the power-carrying member 400 is the power-on state. In the power-on state, the conductive clip 500 is in contact with the two conductive connecting plates 430 at the same time. The power is cut off after the button 300 is pressed, and in the power-off state, the conductive clip 500 is only in contact with the conductive connecting plate 430 below.

[0083] like Fig.17 As shown, taking the example of the power-carrying member 400 including two conductive connecting plates 430, the two conductive connecting plates 430 in the power-carrying member 400 are overall close to the bottom of the plug 410, and the initial state of the power-carrying member 400 is a power-off state. In the power-off state, the conductive clip 500 only contacts the upper conductive connecting plate 430. After the button 300 is pressed, power is turned on, and in the power-on state, the conductive clip 500 contacts the two conductive connecting plates 430 at the same time.

[0084] In summary, the embodiment of the present application provides a switch, which prevents the migration of the metal conductor layer and causes the circuit to be energized incorrectly, causing false alarms and false records of electrical devices, by setting a conductive portion at the plug 410 adjacent to the two conductive connecting plates 430.

[0085] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
