Description

Technical Field

[0001] This utility model relates to the field of PCB board technology, and in particular to a general testing platform for PCBs. Background Technology

[0002] A PCB, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for the electrical interconnection of these components.

[0003] Before PCB boards are manufactured and shipped, they generally need to undergo OQC (Outgoing Quality Control) inspection, which is the outgoing inspection. The electrical control box of the test platform used to inspect PCB boards is usually located inside the box. Most existing boxes have a door on the front to facilitate wiring operations. Since the electrical control box has multiple sides that need to be wired, wiring holes also need to be opened on the side of the box so that fingers can be inserted into the box to make wiring. This is inconvenient and troublesome, and the wiring efficiency is low. Utility Model Content

[0035] Reference Figures 1 to 3 According to the present invention, a general testing platform for PCBs includes a housing 100, a first opening 110 on the front, and second openings 120 on the left and right sides. A first magnetic chuck 111 is provided at the first opening 110, and a second magnetic chuck 121 is provided at the second opening 120. A first door 200 is magnetically connected to the housing 100 via the first magnetic chuck 111 and is used to close the first opening 110. Two second doors 300 are magnetically connected to the housing 100 via the second magnetic chuck 121 and are used to close the second openings 120.

[0036] By opening a first opening 110 on the front side of the enclosure 100 and second openings 120 on the left and right sides, wiring of the electrical control box 400 inside the enclosure 100 can be performed directly with both hands without having to insert fingers into the openings. This greatly facilitates wiring and unwielding of the electrical control box 400. At the same time, the first magnetic clasp 111 and the second magnetic clasp 121 magnetically connect the first door 200 and the second door 300, which can close the enclosure 100 while facilitating the assembly and disassembly of the first door 200 and the second door 300. The operation is simple and quick.

[0037] The application of the above-mentioned general-purpose test platform for PCBs has at least the following beneficial effects: By setting a first opening 110 on the front side of the housing 100 and setting second openings 120 on both the left and right sides, the first opening 110 is closed by connecting the first door 200 through the first magnetic suction member 111 at the first opening 110, and the second opening 120 is closed by connecting the second door 300 through the second magnetic suction member 121 at the second opening 120. During the wiring process, the first door 200 and the second door 300 can be removed from the housing 100 to wire the electrical control box 400 inside the housing 100. After the wiring is completed, the first door 200 and the second door 300 are installed on the housing 100, and the first door 200 and the second door 300 are magnetically connected by the first magnetic suction member 111 and the second magnetic suction member 121. This facilitates the wiring operation and the opening and assembly of the first door 200 and the second door 300, thereby improving testing efficiency.

[0038] According to some embodiments of this utility model, the first door 200 and the second door 300 are both made of magnetic metal, that is, iron, cobalt, or nickel, preferably iron; in some other embodiments, the first door 200 and the second door 300 can also be made of non-magnetic metal, and a third magnetic chuck is provided at the position of the first magnetic chuck 111 on the first door 200 and at the position of the second magnetic chuck 121 on the second door 300 to achieve the same effect. In this embodiment, the first door 200 and the second door 300 can also be made of transparent material to facilitate observation of the equipment inside the enclosure 100.

[0039] According to some embodiments of this utility model, a U-shaped door frame 130 is provided on the front side of the box 100, and a first opening 110 is restricted between the U-shaped door frame 130 and the bottom of the box 100. Magnetic suction members are provided on the U-shaped door frame 130. The U-shaped door frame 130 includes a first side 131 on the left and right sides and a second side 132 on the upper side. At least two first magnetic suction members 111 are provided on the front side of the first side 131 and the front side of the second side 132. It can be understood that the U-shaped door frame 130... The opening faces downwards, with first side 131 on both sides and second side 132 on the top. A first side 131 is connected to each side of the second side 132. By setting at least two first magnetic suction pieces 111 on the first side 131 and the second side 132 respectively, the magnetic attraction force on the first box door 200 is increased, while ensuring the uniformity of the attraction on the first box door 200. This ensures that the first box door 200 is completely attached to the U-shaped door frame 130 and the first opening 110 is properly closed.

[0040] According to some embodiments of this utility model, a first square groove 131a is provided on the first side 131 for opening the second box door 300, and a second square groove 140 is provided at the bottom of the box body 100 for opening the first box door 200. During assembly, the first box door 200 needs to be placed at the first opening 110, and the first box door 200 is attracted to the U-shaped door frame 130 by the action of the first magnetic suction member 111. The second box door 300 is handled similarly. During disassembly, insert your fingers into the second square groove 140 and pull the first door 200 outward to disengage it from the attraction of the first magnetic chuck 111, thus removing the first door 200. Then, insert your fingers into the first square groove 131a and pull the second door 300 outward to disengage it from the attraction of the second magnetic chuck 121, thus removing the second door 300. This allows you to perform wiring and disconnection operations on the front and left and right sides of the electrical control box 400.

[0041] According to some embodiments of the present invention, a second magnetic member 121 is provided on the side of the two first sides 131 that are far apart from each other. The second magnetic member 121 is used to magnetically connect the second box door 300. A sloping frame 150 is also provided at the second opening 120 of the box body 100. At least two second magnetic members 121 are provided on the sloping frame 150. Through the combination of the first side 131 and the sloping frame 150, the second opening 120 and the second box door 300 form a right-angled trapezoidal shape, which improves the overall aesthetics of the test platform.

[0042] According to some embodiments of the present invention, the first magnetic suction member 111 and the second magnetic suction member 121 are both circular magnets, and the circular magnets are fixedly connected to the housing 100.

[0043] According to some embodiments of this utility model, the left and right sides of the housing 100 are provided with louvered heat dissipation holes 160, which are arranged at an angle to improve the overall aesthetics of the test platform. A heat dissipation component 170 is provided on the rear side, which can be set as a cooling fan or some existing water cooling devices.
