Description
Technical Field
[0001] This application relates to the field of power strips, and in particular to a novel 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 and a socket assembly. The housing contains a circuit module. The socket assembly includes a ground socket, a first socket, and a second socket. The ground socket is electrically connected to the circuit module via solder wires, the first socket is electrically connected to the circuit module via solder wires, and the second socket is electrically connected to the circuit module via solder wires.
[0004] Regarding the aforementioned technologies, when power strips are used in factories or similar locations, the sudden and violent fluctuations in voltage or current caused by the switching on or off of high-power equipment can easily damage the power strip by the electrical wires connecting the circuit module and the socket assembly. Summary of the Invention
[0005] To prevent the electrical connection between the circuit module and the socket assembly from being broken down and damaged when the voltage or current of the power strip fluctuates drastically, this application provides a novel power strip.
[0006] The novel power strip provided in this application adopts the following technical solution:
[0007] A novel power strip includes a housing, a circuit module, and a socket assembly. The circuit module is fixedly installed inside the housing and is used to supply power while ensuring user safety and stable equipment operation.
[0008] The circuit module has a through grounding connection hole, a first connection hole, and a second connection hole. The grounding socket assembly includes a grounding socket, a first socket, and a second socket. The grounding socket, the first socket, and the second socket are all fixedly disposed inside the housing. One end of the grounding socket passes through and is electrically connected to the grounding connection hole, one end of the first socket passes through and is electrically connected to the first connection hole, and one end of the second socket passes through and is electrically connected to the second connection hole.
[0009] By adopting the above technical solution, when the power strip is used in factories or other places, and high-power equipment in the factory is turned on or off, or when it is struck by lightning or the power grid fluctuates, causing a sudden and violent fluctuation in voltage or current in the power strip, the circuit module and the socket assembly are directly connected. This allows the violently fluctuating voltage or current in the ground socket, the first socket, and the second socket to be quickly guided to the ground wire through the circuit module, thereby preventing the connection between the circuit module and the socket assembly from being broken down. This makes the power strip less prone to damage and improves the problem that when the power strip is used in factories or other places, and high-power equipment in the factory is turned on or off, causing a sudden and violent fluctuation in voltage or current in the power strip, the wires used for electrical connection between the circuit module and the socket assembly are easily broken down by the violently fluctuating voltage or current, leading to damage to the power strip.
[0010] Optionally, a USB module is fixedly installed inside the housing. The USB module is electrically connected to the circuit module. The USB module is fixedly and electrically connected to a USB module. The housing has a through-hole USB hole through which the USB module passes.
[0011] Optionally, one end of the USB module has a through-hole first connection slot and a second connection slot. When the USB module and the circuit module are electrically connected, the end of the first socket away from the circuit module passes through and is electrically connected to the first connection slot, and the end of the second socket away from the circuit module passes through and is electrically connected to the second connection slot, so that the USB module and the circuit module are electrically connected.
[0012] Optionally, the circuit module is fixedly and electrically connected to an indicator light, and the housing has a through-hole for the indicator light to pass through, which is used to indicate the power-on status of the power strip.
[0013] Optionally, the circuit module is fixedly and electrically connected to a surge protection element, which is used to prevent damage to the power strip due to drastic voltage or current fluctuations.
[0014] Optionally, the surge protection element includes a varistor, a thermal fuse, and a heat shrink tubing. The varistor and the thermal fuse are electrically connected to the circuit module, and the heat shrink tubing is wrapped around the varistor and the thermal fuse.
[0015] Optionally, the circuit module is fixedly and electrically connected to a switch module, and the housing has a through-hole switch slot, through which the switch module is inserted and fixed.
[0016] Optionally, the housing has multiple snap-fit slots, each of which has a snap-fit block inside. Each snap-fit block includes an elastic part and a snap-fit part, which are fixedly connected. Each elastic part is fixedly connected to the slot body of each snap-fit slot. Each elastic part is elastic. The snap-fit part is inclined from top to bottom from the side away from the housing to the side closer to the housing, so that the connection between the power strip and the device is more stable.
[0017] Optionally, the housing includes a main housing portion and a bottom housing portion, which are fixedly connected. The main housing portion is fixedly provided with a sealing protrusion ring, and the bottom housing portion is provided with a sealing groove. When the main housing portion and the bottom housing portion are fixedly connected, the sealing protrusion ring passes through the sealing groove and abuts against the bottom of the sealing groove.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. When power strips are used in factories or similar locations, and high-power equipment is turned on or off, or when lightning strikes or power grid fluctuations occur during use, causing momentary and drastic voltage or current fluctuations in the power strip, the direct connection between the circuit module and the socket assembly allows the rapidly fluctuating voltage or current in the ground socket, first socket, and second socket to be quickly conducted to the ground wire through the circuit module. This prevents the connection between the circuit module and the socket assembly from being broken down, thus reducing the likelihood of damage to the power strip. This addresses the problem that when power strips are used in factories or similar locations, and high-power equipment is turned on or off, causing momentary and drastic voltage or current fluctuations in the power strip, the wires used for electrical connection between the circuit module and the socket assembly are easily broken down by the drastic voltage or current fluctuations, leading to damage to the power strip.

[0030] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0031] This application discloses a novel power strip. (Refer to...) Figure 1 and Figure 2 A novel power strip includes a housing 1, a circuit module 2, a USB module 3, and a socket assembly 4.
[0032] Reference Figure 2 and Figure 3 The housing 1 includes a main housing part 11 and a bottom housing part 12. The main housing part 11 and the bottom housing part 12 are fixedly connected by screws. The main housing part 11 is fixedly provided with a sealing protrusion ring 111, and the bottom housing part 12 is provided with a sealing groove 121. When the main housing part 11 and the bottom housing part 12 are fixedly connected, the sealing protrusion ring 111 passes through the sealing groove 121 and abuts against the bottom of the sealing groove 121.
[0033] Reference Figure 3 and Figure 4The main housing 11 has multiple snap-fit slots 112, and each snap-fit slot 112 is provided with a snap-fit block 113. Each snap-fit block 113 includes an elastic part 1131 and a snap-fit part 1132. The elastic part 1131 and the snap-fit part 1132 are fixedly connected. Each elastic part 1131 is fixedly connected to the groove of each snap-fit slot 112. Each elastic part 1131 is elastic. The snap-fit part 1132 is inclined from top to bottom from the side away from the housing 1 to the side closer to the housing 1, so that the connection between the power strip and the device is more stable.
[0034] Reference Figure 5 Both the circuit module 2 and the USB module 3 are located inside the housing 1. The main housing 11 is fixedly provided with multiple fixing ribs 114, and the bottom housing 12 is fixedly provided with multiple fixing rods 122. When the circuit module 2 and the USB module 3 are fixedly located inside the housing 1, one side of the circuit module 2 and one side of the USB module 3 are abutted and fixed with each fixing rib 114, and the other side of the circuit module 2 and the other side of the USB module 3 are abutted and fixed with each fixing rod 122.
[0035] Reference Figure 5 Circuit module 2 is fixed and electrically connected to surge protection element 21. Surge protection element 21 is used to prevent damage to the power strip due to drastic voltage or current fluctuations. Surge protection element 21 includes a varistor, a thermal fuse, and a heat shrink tubing. The varistor and thermal fuse are electrically connected to circuit module 2. The heat shrink tubing is wrapped around the varistor and thermal fuse, so that when the voltage exceeds the threshold, the varistor quickly conducts, thereby guiding the surge energy to the ground wire and protecting the downstream equipment.
[0036] Reference Figure 5 and Figure 6 The circuit module 2 is fixed and electrically connected to an indicator light 22. The main housing 11 has a through-hole 115 through which the indicator light 22 passes. The indicator light 22 is used to indicate the power-on status of the power strip.
[0037] Reference Figure 5 and Figure 6 The circuit module 2 is fixed and electrically connected to the switch module 23. The housing 1 has a through-hole switch slot 116, and the switch module passes through and is fixed in the switch slot 116.
[0038] Reference Figure 5 and Figure 6 The USB module 3 is fixed and electrically connected to the USB module 31. The housing 1 has a through USB hole 117 through which the USB module 31 passes.
[0039] Reference Figure 7 , Figure 8 as well as Figure 9The socket assembly 4 includes a grounding socket 41, a first socket 42, and a second socket 43. All three sockets are fixedly installed inside the housing 1. The circuit module 2 has a through-hole grounding connection hole 24, a first connection hole 25, and a second connection hole 26. One end of the grounding socket 41 passes through and is electrically connected to the grounding connection hole 24; one end of the first socket 42 passes through and is electrically connected to the first connection hole 25; and one end of the second socket 43 passes through and is electrically connected to the second connection hole 26. 6. One end of the USB module 3 has a through-hole first connection slot 32 and a through-hole second connection slot 33. When the USB module 3 and the circuit module 2 are electrically connected, the end of the first socket 42 away from the circuit module 2 passes through and is electrically connected to the first connection slot 32, and the end of the second socket 43 away from the circuit module 2 passes through and is electrically connected to the second connection slot 33, so that the USB module 3 and the circuit module 2 are electrically connected, thereby making the electrical connection between the USB module 3 and the circuit module 2 less susceptible to breakdown by drastic voltage or current changes.
[0040] Reference Figure 5 and Figure 6 The top of the main housing 1 has multiple through grounding sockets 118, multiple through first sockets 119, and multiple through second sockets 110. The grounding socket 41 has multiple grounding holes 411 that are respectively opposite to each grounding socket 118. The first socket 42 has multiple first holes 421 that are respectively opposite to each first socket 119. The second socket 43 has multiple second holes 431 that are respectively opposite to each second socket 110.
[0041] The implementation principle of a novel power strip according to an embodiment of this application is as follows: When the power strip is used in a factory or other place, and high-power equipment in the factory is turned on or off, or when it is struck by lightning or the power grid fluctuates during use, causing a sudden and violent fluctuation in the voltage or current in the power strip, the circuit module 2 and the socket assembly 4 are directly connected. This allows the violently fluctuating voltage or current in the ground socket 41, the first socket 42, and the second socket 43 to be quickly guided to the ground wire through the circuit module 2, thereby preventing the connection between the circuit module 2 and the socket assembly 4 from being broken down. This makes the power strip less prone to damage and improves the problem that when the power strip is used in a factory or other place, and high-power equipment in the factory is turned on or off, causing a sudden and violent fluctuation in the voltage or current in the power strip, the wires used for electrical connection between the circuit module 2 and the socket assembly 4 are easily broken down by the violently fluctuating voltage or current, thus causing damage to the power strip.
[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.
