Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a connection control structure for a switching power supply. Background Technology

[0002] Switches are mainly used for connecting and controlling power supplies, such as... Figure 7 As shown, a switch typically consists of an upper housing, a lower housing, two fixed terminals, and a connection and control structure comprised of a movable terminal, a column, a pressure spring, and a button. The movable terminal is rotatably mounted on the lower housing and is always connected to one of the fixed terminals. It is designed with a V-shape. When the button is pressed, the column rotates along the button's axis, and the spring presses down on the other end of the movable terminal, connecting it to the other fixed terminal and thus completing the circuit. Conversely, resetting the switch returns it to its original position. Figure 7 The circuit is disconnected at the location shown.

[0003] This type of power connection control structure is easy to operate and has a low failure rate. Therefore, most switches on the market use this type of connection control structure to control the power supply. However, due to the lack of a safety lock function and the fact that the button is subject to the action of a pressure spring, when the raised end of the button is pressed down to a certain position, it will automatically press down, thereby changing the circuit state of the two fixed terminals. As a result, accidental touches or violent vibrations often occur, causing changes in the circuit state. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a switching power supply connection control structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A switching power supply connection control structure includes a mounting box and a partition slidably disposed inside the mounting box. The partition divides the interior of the mounting box into a setting cavity and an operating cavity. A first spring is disposed in the operating cavity for elastically connecting the inner wall of the mounting box and the partition. A slidable limiting component passes through the side wall of the operating cavity. One side of the limiting component is elastically connected to the partition via a second spring.

[0007] Preferably, the mounting box includes a housing, which is a hollow cuboid structure. Several limiting strips are provided on both of the two opposite inner walls of the mounting box, and a sliding opening that matches the limiting component is provided on one side of the housing.

[0008] Preferably, the partition includes a vertical plate, and both ends of the vertical plate are provided with grooves that match the limiting strip.

[0009] Preferably, the limiting component includes a horizontal plate and a limiting plate disposed on one side of the horizontal plate. The size of the limiting plate is larger than the size of the sliding opening, and a plurality of second springs corresponding to the second springs are disposed on one side of the limiting plate.

[0010] Preferably, the top of the housing is provided with an installation port corresponding to the mounting cavity.

[0011] Preferably, it also includes a rubber block disposed within the cavity, with both sides of the rubber block contacting the two sides of the cavity respectively.

[0012] This utility model has the following beneficial effects:

[0013] 1. The limiting component set in this utility model can block the side of the button that is pressed down when it is pressed, preventing accidental touch. This makes the push-button switch less susceptible to external interference or reverse force, avoiding the risk of the button being accidentally lifted or rebounding.

[0014] 2. This utility model, by setting a mounting cavity, allows users to selectively use it according to their own needs. When needed, the rubber block is placed in the mounting cavity. Through the support of the rubber block, the partition is moved to the appropriate position, so that the limiting component can be smoothly ejected under the action of the second spring. When not needed, the rubber block is removed, and under the action of the first spring, the partition is pushed into the mounting cavity, so that the limiting component retracts into the interior of the working cavity, thereby avoiding the impact on the button.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-7 A switching power supply connection control structure includes a mounting box 1 and a partition 2 slidably disposed inside the mounting box 1. The partition 2 divides the interior of the mounting box 1 into a setting cavity 3 and an operating cavity 4. A first spring 5 is disposed in the operating cavity 4 for elastically connecting the inner wall of the mounting box 1 and the partition 2. A slidable limiting component 7 passes through the side wall of the operating cavity 4. One side of the limiting component 7 is elastically connected to the partition 2 by a second spring 6.

[0025] In this embodiment, by installing two mounting boxes 1 on both sides of button 15, when the partition 2 is in a certain position, the limiting component 7 can be popped out by the action of the second spring 6, so that the limiting component 7 is directly above the side of button 15 that is pressed down. When the side of button 15 that is pressed down is lifted due to accidental touch, the limiting component 7 above it can limit the lifting of the side of button 15 that is pressed down, thereby maintaining the connection state of the switch. When it is necessary to change the connection state of the switch, the user can move the limiting component 7 towards the mounting box 1 and then press the button 15. After the switch state is changed, the user can release the moving limiting component 7. The limiting component 7 will pop out under the action of the second spring 6. However, at this time, the part of button 15 that is lifted will block the limiting component 7 from popping out further, while the other limiting component 7 is fully popped out, thereby achieving the limiting of the other end of button 15. When installing the mounting box 1, an adhesive such as glass glue can be used for installation, or a hole can be made in the upper housing 9 and screws can be used to fix the mounting box 1 to the top of the upper housing 9.

[0026] In this utility model, the mounting box 1 includes a box body 101, which is a hollow cuboid structure. The two opposite inner walls of the mounting box 1 are provided with a plurality of limiting strips 102, and a sliding opening 103 matching the limiting component 7 is provided on one side of the box body 101.

[0027] In this embodiment, the partition 2 can be limited by the limiting strip 102, and the partition 2 can slide along the direction of the limiting strip 102. The sliding opening 103 can provide a certain space for the movement of the limiting component 7, while limiting the limiting component 7 and preventing the limiting component 7 from popping out completely. The installation opening 104 can place items into the setting cavity 3.

[0028] In this utility model, the partition 2 includes a vertical plate 201, and the two ends of the vertical plate 201 are provided with grooves 202 that match the limiting strip 102.

[0029] In this embodiment, the position of the vertical plate 201 is restricted by matching the groove 202 with the limiting strip 102. The vertical plate 201 provides a certain connection point for the first spring 5 and the second spring 6. The elastic force of the second spring 6 can be changed by moving the partition 2. When the partition 2 is moved into the setting cavity 3 under the action of the first spring 5, the partition 2 will pull the limiting component 7 back through the second spring 6.

[0030] In this utility model, the limiting component 7 includes a horizontal plate 701 and a limiting plate 702 disposed on one side of the horizontal plate 701. The size of the limiting plate 702 is larger than the size of the sliding opening 103. A plurality of second springs 6 corresponding to the second springs 6 are disposed on one side of the limiting plate 702.

[0031] In this embodiment, the movement of button 15 can be restricted by setting limit component 7, thereby maintaining the state of button 15.

[0032] In this utility model, the top of the housing 101 is provided with an installation port 104 corresponding to the mounting cavity 3.

[0033] In this embodiment, the rubber block 8 can be removed or placed into the cavity 3 by setting the installation port 104, thereby adjusting the position of the partition 2.

[0034] This invention also includes a rubber block 8 disposed in the cavity 3, with the two sides of the rubber block 8 contacting the two sides of the cavity 3 respectively.

[0035] In this embodiment, the rubber block 8 can serve as a support for the partition 2. When the rubber block 8 is placed inside the setting cavity 3, it supports the partition 2, allowing the limiting component 7 to be ejected smoothly, thereby restricting the position of the button 15. After the rubber block 8 is removed, the partition 2 loses its support. Under the action of the first spring 5, the partition 2 is pushed into the setting cavity 3, and the setting cavity 3 pulls the limiting component 7 into the action cavity 4, thereby eliminating the restriction on the button 15. When the user needs to restrict the button 15, the rubber block 8 is placed into the setting cavity 3. When the button 15 no longer needs to be restricted, the rubber block 8 can be removed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
