Wiring board

Abstract

The invention provides a wiring board comprising a top cover, a middle frame, and a bottom casing. The top cover is equipped with dual-purpose jacks and single jack baffle plates equipped with elastic repositioning mechanisms. Each single jack baffle plate is provided with a guiding slope on which a metallic slice is fixed. The top cover is equipped with USB sockets. One inner sidewall of each USB socket on the top cover is provided with a USB guiding slope. Each USB socket on the top cover is correspondingly provided with a USB baffle plate equipped with an elastic repositioning mechanism. Each USB baffle plate comprises a transverse sealing plate and a vertical pushing plate. The bottom casing is provided with a plurality of screw bolts. The middle frame is provided with a screw placing vertical groove. The screw placing vertical groove is provided with a screw nut stopping step. The inner sidewall of the top cover is connected with the outer sidewall of the middle frame through a buckling structure. The wiring board has beneficial effects that one baffle plate seals two jacks so as to simplify structure; each baffle plate is provided with the metallic slice so as to effectively prevent a plug from being jammed; each USB baffle plate is provided with the vertical pushing plate so as to achieve simple structure and stable and reliable operation; the middle frame is in screw connection with the bottom casing and the top cover is in buckled connection with the middle frame such that fast assembly and good firmness are achieved.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a plug board. Background technique [0002] The existing plug-in boards have the following three problems: 1. Generally, there are dual-purpose jacks with two eyes (suitable for round-pin plugs and blade-type plugs), and most of them do not have a jack baffle structure, which poses a safety hazard; Some plug-in boards with baffle structure use two baffles as the baffle of the dual-purpose socket, which has a complex structure, high processing precision requirements, and difficult to guarantee the stability of the action; [0003] 2. At present, most of the plug-in boards with USB interface on the market have their USB ports directly exposed, which poses a safety hazard; their surface is not beautiful, and some plug-in boards with a USB jack baffle structure have a complicated USB jack baffle structure, and the movement Poor stability; [0004] 3. The upper cover, middle ...

[0002] The existing plug-in boards have the following three problems: 1. Generally, there are dual-purpose jacks with two eyes (suitable for round-pin plugs and blade-type plugs), and most of them do not have a jack baffle structure, which poses a safety hazard; Some plug-in boards with baffle structure use two baffles as the baffle of the dual-purpose socket, which has a complex structure, high processing precision requirements, and difficult to guarantee the stability of the action;

[0003] 2. At present, most of the plug-in boards with USB interface on the market have their USB ports directly exposed, which poses a safety hazard; their surface is not beautiful, and some plug-in boards with a USB jack baffle structure have a complicated USB jack baffle structure, and the movement Poor stability;

[0004] 3. The upper cover, middle frame, and bottom case are all connected by screws, which can be disassembled by the user at will. At the same time, exposing the screws is easy to rust and affect the environment. There are a large number of sockets, wires and other components in the middle frame. Displacement may cause faults such as short circuit or open circuit, so it is prone to man-made damage, and there are many small parts, allowing the middle frame to be disassembled will easily cause parts to be lost

In summary, the existing plug-in board structure needs to be improved
