[0042] like Figure 1 As shown, an embodiment of this application provides a power strip 100, including a housing 10, multiple socket modules 20, a USB charging module 30, and a waterproof cover 40. The housing 10 includes a bottom shell 11, an inner frame 12, and an outer shell 13. The inner frame 12 is disposed on the bottom shell 11 and detachably connected to the bottom shell 11. The outer shell 13 covers the inner frame 12 and is detachably connected to the bottom shell 11. Multiple socket modules 20 are installed on the inner frame 12, wherein each socket module 20 has a socket hole 21 that penetrates the outer shell 13 for a power plug (not shown). The USB charging module 30 is mounted on the inner frame 12, wherein the USB charging port 31 of the USB charging module 30 passes through the outer shell 13 for plugging and unplugging the power data cable (not shown); a waterproof cover 40 is correspondingly provided with the USB charging module 30, one end of the waterproof cover 40 is located between the inner frame 12 and the outer shell 13 and is connected to the inner frame 12, and the waterproof cover 40 can rotate relative to the outer shell 13 to control the opening / closing of the USB charging port 31 on the corresponding USB charging module 30. Here, the waterproof cover 40 is configured as a plastic part.
[0043] It is understandable that the waterproof cover 40 is used to control the opening / closing of the USB charging port 31 on the USB charging module 30, thus giving the USB charging port 31 on the extension cord 100 a waterproof and dustproof function; at the same time, the outer shell 13 covers the connection between the waterproof cover 40 and the inner frame 12, which on the one hand protects the connection between the waterproof cover 40 and the inner frame 12, and on the other hand ensures that the setting of the waterproof cover 40 does not affect the external shape of the outer shell 13.
[0044] like Figure 2As shown, the bottom shell 11 has a hanging hole 111, through which the extension cord 100 can be suspended. This allows the extension cord 100 to be mounted on a target object such as a wall by attaching the bottom shell 11 to it, and then using screws mounted on the target object to insert into the hanging hole 111, thus facilitating its use. Here, the hanging hole 111 is designed as a gourd-shaped hole.
[0045] like Figure 2 As shown, the projection of the outer casing 13 onto the bottom casing 11 along the thickness direction of the extension cord 100 can cover the hanging holes 111. Here, there are four hanging holes 111, which are symmetrical in pairs, so that the extension cord 100 can be hung upright or upside down according to the usage requirements.
[0046] like Figure 1 , Figure 2 As shown, a plurality of hanging plates 112 are formed on the bottom shell 11. The plurality of hanging plates 112 are symmetrically located on the outer sides of both ends of the outer shell 13, and the extension cord 100 can be suspended and installed through the hanging plates 112. That is to say, the extension cord 100 can also be suspended and installed using the hanging plates 112 according to different usage needs, so as to meet different user needs.
[0047] like Figure 1 , Figure 2 As shown, multiple suspension plates 112 are symmetrically arranged along the thickness direction of the cable tray 100, so that when the cable tray 100 is suspended by the suspension plates 112, multiple suspension plates 112 can be used together to support the cable tray 100 during suspension installation, thereby improving the stability of the cable tray 100 when suspended by the suspension plates 112. Here, two suspension plates 112 are respectively arranged on the outer side of each end of the cable tray 100 housing 13.
[0048] like Figure 1 As shown, the bottom shell 11 has multiple connecting protrusions 113, which abut against the inner frame 12 to support it. The cable tray 100 also includes multiple first screws 101, each corresponding to one of the connecting protrusions 113. Each first screw 101 passes through the inner frame 12 and is threadedly connected to its corresponding connecting protrusion 113. In other words, the cable tray 100 of this application uses the first screws 101 to lock the inner frame 12 onto the connecting protrusions 113 of the bottom shell 11, thus assembling the inner frame 12 onto the bottom shell 11. During this process, the threaded engagement between the first screws 101 and the corresponding connecting protrusions 113 facilitates the assembly of the inner frame 12 onto the bottom shell 11.
[0049] like Figure 1 , Figure 2 As shown, the bottom shell 11 also has multiple connecting protrusions 114 formed thereon. These connecting protrusions 114 are disposed on both sides of the outer shell 13 and fit against it. The extension cord 100 also includes multiple second screws 102, each corresponding to one of the connecting protrusions 114. Each second screw 102 can pass through its corresponding connecting protrusion 114 and be threadedly connected to the outer shell 13. In other words, the extension cord 100 of this application uses the second screws 102 to lock the outer shell 13 onto the connecting protrusions 114 of the bottom shell 11, thus assembling the outer shell 13 onto the bottom shell 11. Here, there are eight connecting protrusions 114, symmetrically arranged on both sides of the outer shell 13 in the width direction. It should be noted that the number of connecting protrusions 114 can be specifically set according to the length of the extension cord 100, which will not be elaborated upon here.
[0050] In this application, the housing 13 is configured as a metal housing 130; wherein, a grounding wire (not shown) is electrically connected to the socket module 20, and one end of the grounding wire away from the socket module 20 is connected to the inner peripheral wall of the metal housing 130 to ground the metal housing 130. This method, compared to locking the grounding wire to the metal housing 130 with screws, ensures that the grounding of the metal housing 130 on the extension cord 100 does not affect the external shape of the metal housing 130. Here, the grounding wire is connected to the inner peripheral wall of the metal housing 130 by welding. Of course, those skilled in the art can also use magnetic attraction or a flip-top cover to achieve the connection between the grounding wire and the inner peripheral wall of the metal housing 130, which will not be elaborated here.
[0051] like Figure 1 As shown, the socket modules 20 are arranged sequentially at intervals along the length of the extension cord 100. Here, there are six socket modules 20, which are positioned along the same length as the USB charging module 30 on the extension cord 100. It should be noted that the USB charging module 30 in this application is a single unit, which has two USB charging ports 31. One USB charging port 31 is configured as USB-A, and the other is configured as USB-C, to meet different user needs.
[0052] like Figure 1 As shown, a bent plate portion 41 is formed on the waterproof cover plate 40, and the bent plate portion 41 is attached to the inner frame 12; wherein, the cable tray 100 also includes a connector 401, which passes through the bent plate portion 41 and is connected to the inner frame 12 to limit the bent plate portion 41 to the inner frame 12, thereby realizing the assembly of the waterproof cover plate 40 on the inner frame 12.
[0053] like Figure 1 As shown, an extending protrusion 121 is formed on the inner frame 12. The extending protrusion 121 can be inserted into the bent plate portion 41 and positioned for assembly of the waterproof cover 40 on the inner frame 12. The connecting member 401 is threadedly connected to the extending protrusion 121. This allows the waterproof cover 40 to be positioned on the inner frame 12 during assembly by first using the insertion engagement between the extending protrusion 121 and the bent plate portion 41, and then using the threaded engagement between the connecting member 401 and the extending protrusion 121 to limit the waterproof cover 40's position on the inner frame 12. This facilitates the assembly of the waterproof cover 40 onto the inner frame 12. Specifically, the connecting member 401 can be a screw, bolt, or similar component.
[0054] In this application, the extension cord 100 also includes an overload switch (not shown), which is electrically connected to the socket module 20 and is used to provide overload protection for the extension cord 100, thus giving the extension cord 100 an overload protection function. It should be noted that the specific structure of the overload switch and the working principle of how it provides overload protection to the extension cord 100 can all adopt existing conventional methods, and will not be elaborated upon here.
[0055] like Figure 1 As shown, the extension cord 100 of this application also integrates a surge protection module (not shown) and a grounding module (not shown). The surge protection module is used to realize the surge protection function of the extension cord 100. Specifically, the surge protection indicator 51 can be used to indicate whether the surge protection function of the extension cord 100 has failed. Similarly, the grounding indicator 52 can be used to indicate whether the grounding function of the extension cord 100 has failed. Here, the surge protection performance of the extension cord 100 is improved by increasing the number of varistors in the surge protection module. Specifically, the surge protection function of the extension cord 100 can be designed to be 2100 Joules.
[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
