Description

Technical Field

[0001] This application relates to the field of power strips, and more particularly to a control switch and power strip for a power strip. Background Technology

[0002] A power strip with multiple sockets is a multi-outlet socket, also known as a power strip or power strip. A power strip refers to a multi-outlet socket with a power cord and plug that can be moved around, allowing more than one power plug to be connected, saving both space and wiring.

[0003] Existing power strips generally include a housing, a socket assembly, and a control switch. The socket assembly is located in the housing and forms a plug position. The control switch is used to control the power on or off of the plug position. In order to indicate the on / off status of the plug position circuit, an LED is usually electrically connected to the control switch. When the control switch controls the plug position to be powered on, the LED lights up to indicate that the plug position is in a powered state.

[0004] Regarding the aforementioned technologies, the LED light connected to the control switch can only illuminate the power-on or power-off status of the plug position, but cannot indicate the position of the control switch. This makes it difficult for users to quickly find the control switch corresponding to the power-on plug position in low-light environments, so as to press the control switch to cut off the current to the plug position. Summary of the Invention

[0005] In order to enable users to quickly find the control switch corresponding to the power-on plug position in a low-light environment, this application provides a control switch and a power strip.

[0006] The control switch and power strip provided in this application adopt the following technical solution:

[0007] A control switch for a power strip includes a switch body, a pressing structure, and a pressing switch. The switch body is provided with a first metal plate, a second metal plate, and a metal spring. The pressing structure is disposed on the switch body and abuts against the metal spring. When the pressing structure is driven, the pressing structure pushes the metal spring and the second metal plate into contact and electrical connection. The pressing structure maintains the contact between the metal spring and the second metal plate until the pressing structure is driven again. The pressing switch slides and engages with the switch body and abuts against the pressing structure. The pressing switch is provided with an illumination module for illuminating the pressing switch. Both the first metal plate and the metal spring are electrically connected to the illumination module.

[0008] In one embodiment of this disclosure, the switch body is provided with at least two conductive springs, one end of each conductive spring abutting against and electrically connected to the lighting module, the other end of at least one conductive spring abutting against and electrically connected to a metal spring sheet, and at least another conductive spring abutting against and electrically connected to a first metal sheet.

[0009] In one embodiment of this disclosure, the push switch includes a light-transmitting part and a pressing part, the light-transmitting part and the pressing part are fixedly connected, the pressing part has a light-transmitting groove, and the transparent part passes through the light-transmitting groove to be exposed to the outside of the push switch.

[0010] In one embodiment of this disclosure, the switch body includes a main body and a fixing part, the fixing part and the main body are snapped together and fixed, and the fixing part fixes the first metal sheet, the second metal sheet and the metal spring sheet to the main body.

[0011] A power strip includes a housing, a socket assembly, and a control switch. The socket assembly and the control switch are both disposed in the housing. The socket assembly includes a neutral wire metal piece, a live wire metal piece, and a ground wire metal piece. The neutral wire metal piece, the live wire metal piece, and the ground wire metal piece form a first insertion position for insertion. The neutral wire metal piece and the live wire metal piece form a second insertion position for insertion. The live wire metal piece is electrically connected to a metal spring contact. The neutral wire metal piece and the first metal piece are connected in parallel.

[0012] In one embodiment of this disclosure, the power strip further includes a plug and a main switch, both of which are disposed in the housing. The plug has a neutral wire, a live wire, and a ground wire. The neutral wire and the neutral wire metal piece of the plug are electrically connected. The ground wire and the ground wire metal piece of the plug are electrically connected. The live wire of the plug is electrically connected to the main switch. The main switch and the second metal piece are electrically connected.

[0013] In one embodiment of this disclosure, the power strip further includes a functional circuit board, which is fixedly disposed in the housing, and the second metal plate and the neutral metal plate are both electrically connected to the functional circuit board to supply power to the functional circuit board.

[0014] In one embodiment of this disclosure, the functional circuit board is fixedly and electrically connected to a charging interface.

[0015] In one embodiment of this disclosure, the housing is fixedly provided with a fixing seat, which is used to fix the neutral wire metal piece, the live wire metal piece and the ground wire metal piece, and to guide the first plug-in position and the second plug-in position.

[0016] In one embodiment of this disclosure, the fixed base has two protective blocks in a sliding fit, and a reset spring is provided between the two protective blocks. The two protective blocks are used to close the first insertion position and the second insertion position to protect the first insertion position and the second insertion position.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] When the control circuit of the control switch is energized, the push switch is pressed, causing it to drive the pressing mechanism. This mechanism pushes the metal spring towards the second metal piece until they contact and become electrically connected. The pressing mechanism then maintains this contact, ensuring a continuous electrical connection. The control circuit is then energized. At this point, the electrical connection between the metal spring and the second metal piece allows current to flow from the second metal piece to the metal spring, thus illuminating the lighting module. The circuit of the block is turned on, causing the lighting module to emit light, which illuminates the push switch to indicate that the control switch is powered on and to mark the position of the push switch. This makes it easier for users to quickly find the powered control switch in low-light environments and drive the push switch. This improves the problem that external LED lights connected to the control switch can only indicate the power on or off status of the plug position through illumination, but cannot provide an indication of the position of the control switch. This makes it difficult for users to quickly find the control switch corresponding to the powered plug position in low-light environments and press the control switch to cut off the current to the plug position.

[0029] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0030] This application discloses a control switch and a power strip according to its embodiments. (Refer to...) Figures 1 to 5 A power strip includes a housing 1, a socket assembly 2, and a control switch 3. Both the socket assembly 2 and the control switch 3 are disposed in the housing 1. The control switch 3 includes a switch body 31, a pressing structure 32, and a push switch 33. The switch body 31 is provided with a first metal piece 311, a second metal piece 312, and a metal spring 313. The pressing structure 32 is disposed in the switch body 31 and abuts against the metal spring 313. When the pressing structure 32 is activated, it pushes the metal spring 313 and the second metal piece 312 into contact and electrical connection. The pressing structure 32 maintains the contact between the metal spring 313 and the second metal piece 312 until the pressing structure 32 is activated again. The push switch 33 slides and engages with the switch body 31 and abuts against the pressing structure 32. The push switch 33 is provided with an illumination module 331 for illuminating the push switch 33. Both the first metal piece 311 and the metal spring 313 are electrically connected to the illumination module 331. The device includes a neutral wire metal piece 21, a live wire metal piece 22, and a ground wire metal piece 23. These pieces form a first insertion point 20a for connection. It should be understood that a second insertion point 20b is also formed between the neutral wire metal piece 21 and the live wire metal piece 22 for connection. The live wire metal piece 22 is electrically connected to a metal spring 313, and the neutral wire metal piece 21 is connected in parallel with the first metal piece 311. Furthermore, when there are multiple first insertion points 20a or second insertion points 20b, the number of live wire metal pieces 22 corresponds to the number of live wire metal pieces 22, and the number of control switches 3 corresponds to the number of live wire metal pieces 22. This allows each live wire metal piece 22 and each metal spring 313 to be fixed and electrically connected. Therefore, it can be understood that the control switch 3 can only control the energization or de-energization of its corresponding first insertion point 20a and second insertion point 20b.

[0031] Reference Figures 1 to 5 It should be understood that when the pressing structure 32 is driven, the pressing structure 32 will push the metal spring 313 and the second metal piece 312 to contact and connect electrically, and the pressing structure 32 will keep the metal spring 313 and the second metal piece 312 in contact until the pressing structure 32 is driven again. At this time, the pressing structure 32 will reset and release the contact with the metal spring 313. In the embodiment of this application, the pressing structure 32 is the pressing structure 32 of the prior art. The specific structure is not specifically limited in this application. Subsequently, the metal spring 313 will reset in the direction away from the second metal piece 312 under its own elastic force, so that the metal spring 313 and the second metal piece 312 will be disconnected from the electrical connection. Preferably, both the metal spring 313 and the second metal piece 312 are provided with metal terminals so that the metal spring 313 and the second metal piece 312 can better achieve contact and electrical connection.

[0032] Reference Figure 2 In this embodiment, the power strip also includes a plug 4 and a main switch 5. Both the plug 4 and the main switch 5 are disposed in the housing 1. The plug 4 has a neutral wire, a live wire, and a ground wire. The neutral wire of the plug 4 is electrically connected to the neutral wire metal piece 21, the ground wire of the plug 4 is electrically connected to the ground wire metal piece 23, the live wire of the plug 4 is electrically connected to the main switch 5, and the main switch 5 is electrically connected to the second metal piece 312. This allows the main switch 5 to control the power on or off of each first plug position 20a and each second plug position 20b. Thus, the power strip can simultaneously perform overall control and individual control of each first plug position 20a and each second plug position 20b, thereby better meeting the user's needs. It should be understood that the main switch 5 is prior art, and this application does not specifically limit this structure.

[0033] Reference Figure 5 In this embodiment of the application, the switch body 31 is provided with at least two conductive springs 314. One end of each conductive spring 314 abuts against and is electrically connected to the lighting module 331, the other end of at least one conductive spring 314 abuts against and is electrically connected to the metal spring 313, and at least another conductive spring 314 abuts against and is electrically connected to the first metal piece 311, so as to realize the electrical connection between the first metal piece 311 / metal spring 313 and the lighting module 331, and to provide a reset elastic force for pressing the switch 33.

[0034] Reference Figure 6In this embodiment, the push switch 33 includes a light-transmitting part 33a and a pressing part 33b, which are fixedly connected. The pressing part 33b has a light-transmitting groove 33b1, through which a transparent part passes to be exposed to the outside of the push switch 33. It can be understood that the light emitted by the lighting module 331 can pass through the light-transmitting part 33a and be irradiated. The setting of the light-transmitting groove 33b1 can make the light emitted by the lighting module 331 more concentrated and conspicuous, and a specific pattern can be irradiated through the light-transmitting groove 33b1 so as to be used to quickly find the specific location of the push switch 33.

[0035] Reference Figure 7 In this embodiment of the application, the switch body 31 includes a main body 31a and a fixing part 31b. The fixing part 31b and the main body 31a are snapped together and fixed. The fixing part 31b fixes the first metal piece 311, the second metal piece 312 and the metal spring piece 313 to the main body 31a.

[0036] Reference Figure 8 and Figure 9 In this embodiment of the application, the power strip also includes a functional circuit board 6, which is fixedly disposed on the housing 1. The second metal piece 312 and the neutral metal piece 21 are both electrically connected to the functional circuit board 6 to supply power to the functional circuit board 6. This allows only the main switch 5 to control the power on or off of the functional circuit board 6. It should be understood that the functional circuit board 6 is fixedly and electrically connected to electronic components such as voltage stabilization and protection circuits. The specific electronic components are not specifically limited in this application.

[0037] Reference Figure 8 and Figure 9 In this embodiment of the application, the functional circuit board 6 is fixedly and electrically connected to the charging interface 61, so that users can quickly charge electronic devices such as mobile devices through the charging interface 61 without the need for an additional charging connector.

[0038] Reference Figure 8 and Figure 9 In this embodiment of the application, the housing 1 is fixedly provided with a fixing seat 11, which is used to fix the neutral wire metal piece 21, the live wire metal piece 22 and the ground wire metal piece 23, thereby making the positions of the neutral wire metal piece 21, the live wire metal piece 22 and the ground wire metal piece 23 more stable, and guiding the first plug-in position 20a and the second plug-in position 20b, so that the user can quickly and stably plug in the first plug-in position 20a or the second plug-in position 20b.

[0039] Reference Figure 8 and Figure 9In this embodiment of the application, the fixed base 11 has two protective blocks 111 that slide together, and a reset spring 112 is provided between the two protective blocks 111. The two protective blocks 111 are used to close the first plug-in position 20a and the second plug-in position 20b to protect the first plug-in position 20a and the second plug-in position 20b. It can be understood that when the user plugs in the first plug-in position 20a or the second plug-in position 20b, the protective block 111 corresponding to the first plug-in position 20a or the second plug-in position 20b can be pushed open separately, thereby realizing the plugging in of the first plug-in position 20a or the second plug-in position 20b.

[0040] This application embodiment also provides a power strip control switch 3, which is the control switch 3 described in the above embodiment.

[0041] The implementation principle of a power strip according to an embodiment of this application is as follows: When the control circuit of the control switch 3 is energized, the push switch 33 is pressed, causing the push switch 33 to drive the pressing structure 32. This causes the pressing structure 32 to push the metal spring 313 toward the direction of the second metal piece 312 until the metal spring 313 and the second metal piece 312 contact and become electrically connected. Subsequently, the pressing structure 32 continues to maintain the contact between the metal spring 313 and the second metal piece 312, thereby maintaining the continuous electrical connection between the metal spring 313 and the second metal piece 312. The control switch 3 then energizes the control circuit. At this time, because the metal spring 313 and the second metal piece 312 are electrically connected, current flows from the first metal spring 313 to the second metal piece 312. The two metal pieces 312 flow to the metal spring 313, thereby turning on the circuit of the lighting module 331 and causing the lighting module 331 to emit light, thus illuminating the push switch 33 to indicate that the control switch 3 is energized and to indicate the position of the push switch 33. This makes it easier for users to quickly find the energized control switch 33 in low-light environments and drive the push switch 33. This improves the problem that the external LED light of the control switch can only indicate the energized or de-energized state of the plug position through illumination, but cannot provide an indication of the position of the control switch. This makes it difficult for users to quickly find the control switch corresponding to the energized plug position in low-light environments and press the control switch to cut off the current to the plug position.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
