Description

Technical Field

[0001] The present application relates to the field of power strips, and in particular to a power strip that is easy to assemble. Background Art

[0002] In the production process of power strips, the parts of each part need to be manufactured first, and then assembled on the production line. There are many ways to assemble and fix power strips on the market, such as screw fixing, snap fixing, and ultrasonic fixing. Among them, the most commonly used assembly method is the snap assembly method.

[0003] In the part of power strip products that use the snap-on assembly method, since there are multiple electronic components and circuit boards inside the power strip, the internal assembly structure is complex. When the layout is unreasonable, it is easy to cause problems such as gaps between the internal module and the shell, step differences, and shell arching. The more complex the internal layout, the greater the difficulty of assembly, the higher the rework rate of the product, and the easier it is to increase labor costs. On the production assembly line, if the internal installation structure of the product is complex and the number and variety of parts are large, once a part is missing or lost due to unreasonable layout, the assembly process on the production line will be difficult to carry out. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides an easy-to-assemble power strip to solve at least one of the above-mentioned technical problems.

[0005] A plug board which is easy to assemble comprises a shell, a power line, a first supporting frame, a first output assembly and a second output assembly located in the shell.

[0006] The first output component and the second output component are integrated with output interfaces, and the output interfaces are respectively formed with jacks on the surface of the shell. The power cords are respectively electrically connected to the first output component and the second output component. One end of the first support frame is snap-connected to the first output component, and the other end is snap-connected to the second output component. The first output component is partially located in the first support frame, and the first support frame is used to fix the inner side wall of the shell and support the first output component.

[0007] Furthermore, the first output assembly includes a first circuit board, and the first circuit board is used to integrate the output interface. One side of the first support frame is buckled and connected to the first circuit board, and the first support frame is used to support the first circuit board.

[0008] Furthermore, the first output component also includes a second circuit board, which is plugged into the first circuit board. The second circuit board is integrated with a voltage conversion circuit for adjusting the charging power of the first output component.

[0009] Furthermore, the first supporting frame, the first output assembly and the second output assembly together form a receiving space, and some electronic components on the first circuit board and the second circuit board are located in the receiving space.

[0010] In one embodiment, the second circuit board is perpendicular to the first circuit board. Wherein, the side wall of the first supporting frame is perpendicular to the first circuit board.

[0011] Optionally, a connecting piece is provided on the inner side wall of the first supporting frame, and the connecting piece is used to fix and support the second circuit board in the first supporting frame. In one embodiment, the connecting piece is a guide rail or a guide groove, so that the second circuit board can be slid along the connecting piece and pushed into the first supporting frame and fixedly connected inside the first supporting frame.

[0012] In one embodiment, in order to meet the needs of more socket expansion, multiple second output components can be provided in the housing. The plug board also includes a second support frame. The second output components are respectively connected to the two sides of the second support frame, and are used to fix the second output components to the inner wall of the housing.

[0013] In actual applications, if multiple adjacent second output components are directly connected, there may be a problem of mutual interference caused by insufficient spacing between the output components. Specifically, the spacing refers to the edge-to-edge distance between the output interfaces of the output components. If this distance is less than the specified value, it will cause insufficient spacing between the sockets outside the output components, and there will be interference between the power cord connectors that need to be inserted, and the sockets cannot be connected at the same time. Therefore, it is necessary to add a second support frame to connect the two adjacent second output components and increase the distance between the output components to reduce interference. In addition, through the connection of the second support frame, support can be provided for the second output components on both sides of the second support frame, and multiple second output components can also be stably fixed in the housing.

[0014] It should be noted that as long as it is possible to connect and fix two adjacent second output components in the shell, and the two adjacent second output components do not interfere with each other during use, other connection structures can also be used, such as increasing the outer extension of the shell of the second output component itself to increase the center distance between the two adjacent second output components, and the second output components can be directly connected.

[0015] Furthermore, the housing includes a first housing and a second housing, and the second housing is connected to one side of the first housing. The first support frame, the first output assembly and the second output assembly are located in the first housing, and the power line passes through the second housing to connect to the second output assembly in the first housing, and the other end is used to connect to an external power source.

[0016] Furthermore, a protrusion is provided on one side of the second shell connected to the first shell, which is used to fix the second shell to one side of the first shell and provide support for the second output component inside the first shell.

[0017] Optionally, a guide member is provided on the inner wall of the shell, and a guide structure cooperating with the guide structure is provided on the first support frame, so as to stably push the first support frame into the shell. In practical applications, the design of the guide member and the guide structure makes the shape of the first support frame and the inner wall of the shell roughly match, which can minimize the gap between the components inside the shell and the inner wall of the shell, reduce the possibility of loosening of internal parts, and enable the components inside the shell to be more firmly installed in the shell.

[0018] Optionally, holes for welding wires are provided on the second circuit board, and wire avoidance grooves are provided on the first support frame corresponding to the holes for avoiding wires for welding wires.

[0019] Furthermore, the output interface integrated in the first output component includes a Universal Serial Bus (USB) interface and / or a Lightning interface, and the second output component includes a power interface such as a two-pin jack and a three-pin jack.

[0020] Specifically, in one embodiment, a buckle is provided at the edge of one end of the first support frame, and the edge of the first circuit board is connected and fixed to one end of the first support frame by the buckle. In actual application, the output interface on the first circuit board is arranged perpendicular to the first circuit board. When the user uses the output interface, he inserts the power cord connector into the output interface, and at this time, a force perpendicular to the first circuit board is generated by the output interface. If the first circuit board is not stably supported, the first circuit board may become loose after multiple uses, causing poor contact, thereby affecting the normal operation of the output interface.

[0021] In one embodiment of the present application, the first circuit board is a rectangular plate, and at least two side edges of the first circuit board are supported by the edge of the first support frame, so that the output interface in the first circuit board can be stably connected to the jack provided on the surface of the shell, eliminating the force generated by the user plugging and unplugging the power cord connector. At the same time, the first support frame can also protect the circuit in the second circuit board and some electronic components on the second circuit board. When the first support frame and the first output component are connected, a protective space is formed for the second circuit board located in the first support frame, so that the installed second circuit board and the first circuit board as well as the circuit and electronic components on the circuit board are not easily damaged.

[0022] It should be noted that the assembly sequence is not fixed. In actual production, adjacent components that have a connection relationship can be assembled first.

[0023] Beneficial effects: The present application provides an easy-to-assemble power strip, comprising a shell, a power cord, and a first support frame, a first output component, and a second output component located in the shell. By providing a first support frame to connect and support each output component, each component in the shell can be connected and assembled into a stable whole. After the overall assembly is completed, the whole can be pushed into the shell to complete the assembly of the whole machine. The parts structure in the power strip is simplified, making the layout of the components in the power strip more reasonable and easy to assemble, which can effectively simplify the process steps in the production and assembly process.

[0040] Example

[0041] This embodiment provides a plug board that is easy to assemble, which can simplify the installation process of the plug board and make the assembly work of the plug board more flexible. The specific structure is as follows: Figure 1 to Figure 6 The specific plan is as follows:

[0042] A plug strip which is easy to assemble comprises a shell 1, a power line 5, a first output assembly 2, a first supporting frame 3 and a second output assembly 4 located in the shell 1.

[0043] The first output component 2 and the second output component 4 are integrated with an output interface 23, and the output interface 23 is respectively formed with a jack 12 on the surface of the housing 1. The power cord 5 is respectively electrically connected to the first output component 2 and the second output component 4. One end of the first support frame 3 is snap-connected to the first output component 2, and the other end is snap-connected to the second output component 4. The first support frame 3 is used to fix the inner wall of the housing 1 and support the first output component 2.

[0044] The first output component 2 includes a first circuit board 21 , and the first circuit board 21 is used for integrating an output interface 23 .

[0045] Furthermore, the first supporting frame 3 is connected to the first circuit board 21 and fixedly connected to the inner wall of the housing 1 to support the first circuit board 21 .

[0046] Furthermore, the first output component 2 further includes a second circuit board 22, which is plugged into the first circuit board 21. The second circuit board 22 is integrated with a voltage conversion circuit for adjusting the charging power of the first output component 2.

[0047] The first support frame 3, the first output assembly 2 and the second output assembly 4 together form a receiving space, and some electronic components on the first circuit board 21 and the second circuit board 22 are located in the receiving space. In one embodiment, the second circuit board 22 is perpendicular to the first circuit board 21. The side wall of the first support frame 3 is perpendicular to the first circuit board 21.

[0048] Optionally, a connector 33 is provided on the inner side wall of the first support frame 3, and the connector 33 is used to fix and support the second circuit board 22 in the first support frame 3. In one embodiment, the connector 33 is a guide rail or a guide groove, so that the second circuit board 22 can be slid along the connector 33 and pushed into the first support frame 3 and fixedly connected inside the first support frame 3.

[0049] In one embodiment, a plurality of second output components 4 are arranged in the housing, and the plug board further comprises a second supporting frame. The second output components 4 are respectively connected to both sides of the second supporting frame for fixing the second output components 4 to the inner wall of the housing.

[0050] In actual applications, when multiple adjacent second output components 4 are directly connected, there may be a problem of mutual interference caused by insufficient spacing between the output components. Specifically, the spacing refers to the edge-to-edge distance between the output interfaces of the output components. If the distance is less than the specified value, it will cause insufficient spacing between the sockets outside the output components, and there will be interference between the power cord connectors that need to be inserted, and the sockets cannot be connected at the same time. Therefore, it is necessary to add a second support frame to connect two adjacent second output components 4, increase the distance between the output components to reduce interference. In addition, through the connection of the second support frame, support can be provided for the second output components 4 on both sides of the second support frame, and multiple second output components can also be stably fixed in the housing.

[0051] It should be noted that, as long as it is possible to connect and fix two adjacent second output components 4 in the housing, and the two do not interfere with each other during use, other connection structures can also be used, such as increasing the outer extension of the housing of the second output component 4 to increase the spacing between two adjacent second output components 4, and the second output components 4 can be directly connected. In one embodiment, when the spacing between the edges of the second output components 4 is greater than 20 mm, there will be no interference between the components, and at this time, the two adjacent second output components 4 can be directly connected.

[0052] Furthermore, the housing includes a first housing 11 and a second housing 13, and the second housing 13 is connected to one side of the first housing 11. The first support frame, the first output assembly and the second output assembly 4 are located in the first housing 11, and the power line is connected to the second output assembly 4 in the first housing 11 through the second housing 13, and the other end is used to connect to an external power source.

[0053] Furthermore, a protrusion 15 is provided on one side of the second housing 13 connected to the first housing 11 , which is used to fix the second housing 13 to one side of the first housing 11 and provide support for the second output assembly inside the first housing 11 .

[0054] Optionally, a guide is provided on the inner wall of the housing 1, and a guide structure 34 cooperating with the guide is provided on the first support frame 3, so as to stably push the first support frame 3 into the housing 1. In practical applications, the design of the guide and the guide structure 34 makes the shapes of the first support frame 3 and the inner wall of the housing 1 roughly match, which can minimize the gap between the components inside the housing 1 and the inner wall of the housing 1, reduce the possibility of loosening of internal parts, and enable the components inside the housing 1 to be more firmly installed in the housing 1.

[0055] Optionally, holes for welding wires are provided on the second circuit board 22, and wire avoidance grooves 35 are provided on the first support frame 3 corresponding to the holes for avoiding wires for welding wires.

[0056] Furthermore, the output interface 23 integrated in the first output component 2 includes a USB interface and / or a Lightning interface, and the second output component 4 is integrated with a power interface including a two-hole jack and a three-hole jack.

[0057] Specifically, in one embodiment, a buckle 31 is provided at the edge of one end of the first support frame 3, and the edge of the first circuit board 21 is connected and fixed to one end of the first support frame 3 through the buckle 31. In actual application, the output interface 23 on the first circuit board 21 is arranged perpendicular to the first circuit board 21. When the user uses the output interface 23, the power cord connector is inserted into the output interface 23, and a force perpendicular to the first circuit board 21 is generated by the output interface 23. If the first circuit board 21 is not stably supported, the first circuit board 21 may become loose after multiple uses, causing poor contact, thereby affecting the normal operation of the output interface 23.

[0058] In one embodiment of the present application, the first circuit board 21 is a rectangular plate, and at least two side edges of the first circuit board 21 are supported by the edges of the first support frame 3, so that the output interface 23 in the first circuit board 21 can be stably connected to the jack 12 set on the surface of the housing 1, eliminating the force generated by the user plugging and unplugging the power cord connector. At the same time, the first support frame 3 can also protect the circuit in the second circuit board 22 and some electronic components on the second circuit board 22. When the first support frame 3 and the first output component 2 are connected, a protective space is formed for the second circuit board 22 located in the first support frame 3, so that the installed first circuit board 21 and second circuit board 22 and the circuits and electronic components on the circuit boards are not easily damaged.

[0059] In one embodiment, the size of the second circuit board 22 and the size of the first support frame 3 are positively correlated with the charging power of the first output component 2. In practical applications, the output interface 23 in the first output component 2 includes a USB interface and / or a Lightning interface. In order to meet the different charging requirements of external devices, the first output component 2 can have a variety of charging power settings. The second circuit board 22 is configured with a voltage conversion circuit for voltage conversion, and the charging power of the USB interface and / or the Lightning interface is positively correlated with the size of the voltage conversion circuit in the second circuit board 22. The greater the charging power, the larger the area occupied by the circuit modules such as the voltage conversion circuit that need to be arranged in the second circuit board 22, and thus the area of ​​the second circuit board 22 is also larger. Since the second circuit board 22 is engaged in the first support frame 3, the larger the area of ​​the second circuit board 22, the larger the first support frame 3 will be.

[0060] In a production process of a power strip including a first support frame 3 and a second output assembly 4, the power strip can be assembled in the following order:

[0061] In the first step, the first circuit board 21, the second circuit board 22 and the output interface 23 are assembled into a first output component 2, and the first output component 2 and one side of the first support frame 3 are connected through the buckle 31 on the edge of the first support frame 3 to form a module;

[0062] In the second step, the first clamping member 32 provided on one side of the first support frame 3 and the second clamping member 41 provided on one side of the second output assembly 4 are matched and connected to each other, so as to assemble the module in the first step and the second output assembly 4 into a whole, thereby completing the assembly of all modules inside the plugboard;

[0063] In the third step, since the first support frame 3 is provided with a guide structure 34 that matches the guide piece on the inner wall of the housing 1, all modules inside the plugboard can be pushed into the housing through the guide piece on the inner wall of the housing 1 at one time, and the second output component 4 and the first output component 2 can be fixedly connected to the jack 12 on the surface of the housing 1 correspondingly;

[0064] The fourth step is to connect the power line 5 to the second output component 4 inside the housing 1 through the through hole 14 on the second housing 13 in the housing 1, and connect the second housing 13 to the housing 1 to complete the entire assembly. Figure 6 shown.

[0065] It should be noted that the assembly sequence is not fixed, and in actual production, adjacent components with a connection relationship may be assembled first, so that the impact of the production progress of each component on the overall assembly progress of the power strip can be reduced.

[0066] The present embodiment provides an easy-to-assemble power strip, including a housing, a power cord, and a first support frame, a first output assembly, and a second output assembly located in the housing. By providing a first support frame to connect and support the first output assembly and the second output assembly, the various components in the housing can be connected and assembled into a stable whole, and after the whole is assembled, it can be pushed into the housing to complete the assembly of the whole machine. The present embodiment simplifies the structure of parts in the power strip, making the layout of the components in the power strip more reasonable, and can effectively simplify the process steps in the production and assembly process, making the coordination between production lines more flexible.
