Abstract
Description
Technical Field
[0001] This utility model relates to the field of port protection, and more specifically, to a port protection structure for exposed PCB boards. Background Technology
[0002] The ports on PCB boards (such as motherboards and driver boards) of conventional electronic devices, such as displays and televisions, are all exposed, making them susceptible to dust and water damage, which reduces their lifespan. Although related technologies add covers to the outside of the exposed ports on the motherboard to protect the motherboard interfaces, these covers are often fixed together with bolts. When it is necessary to open the ports, the bolts need to be removed, which is a cumbersome and inconvenient operation. Utility Model Content
[0003] The purpose of this utility model is to provide an exposed PCB board port protection structure that enables the opening and closing of the opening quickly, and is simple and convenient to operate.
[0004] The embodiments of this utility model are implemented as follows: This application provides an exposed PCB board port protection structure, including a housing, a cover plate, and an adsorption structure. The housing has an opening area opposite to the PCB board port, and the opening area is provided with an opening. The cover plate and the adsorption structure are both located at the opening area, and one side of the cover plate is rotatably connected to the portion of the housing opposite to the opening area. The cover plate is at least partially made of metal, and the adsorption structure is at least partially magnetic. The cover plate has a first position and a second position during rotation. When the cover plate is in the first position, the opening is open. When the cover plate is in the second position, the metal portion of the cover plate is opposite to the magnetic portion of the adsorption structure, and the cover plate blocks the opening.
[0005] In a possible implementation, the adsorption structure includes a baffle and a magnetic element; one side of the baffle and the cover are respectively disposed on opposite inner sides of the opening, and the surface area of the baffle is smaller than the size of the opening; the magnetic element is disposed on the outer side of the baffle, and when the cover is in the second position, the magnetic element is magnetically connected to the inner side of the cover. In a possible implementation, the magnetic element has a set strength of magnetism; wherein the range of the adsorption force provided by the set strength of magnetism is: greater than a first separation force and less than a second separation force, the first separation force being an accidental separation force that causes the cover to open, and the second separation force being an active separation force that causes the cover to open. In a possible implementation, the opening is rectangular in shape, and the baffle includes a main body and two receiving parts. The main body is disposed inside the opening; the two receiving parts are located at both ends of the main body and are disposed inside the two ends of the opening. In a possible implementation, multiple magnetic components are provided and are equally spaced on the outer side of the main body; two receiving portions are symmetrically arranged at both ends of the main body and extend in a direction perpendicular to the extension direction of the main body. In a possible implementation, the cover plate has a rectangular shape, and when the cover plate is in the second position, it covers the magnetic component.
[0006] In a possible implementation, the distance between the outer surface of the magnetic element and the outer surface of the opening is equal to the thickness of the cover plate.
[0007] In a possible implementation, the inner surfaces at both ends of the opening are provided with pivots, and the cover plate has a corresponding connecting hole for the pivot. The pivot extends into the corresponding connecting hole so that the cover plate and the pivot are rotatably connected.
[0008] In a possible implementation, the cover plate has a notch on the side away from the connection hole.
[0009] The beneficial effects of this utility model embodiment are as follows: A PCB board is placed inside the outer shell, and the opening in the opening area of the outer shell is opposite to the PCB board, which facilitates the connection of the end of the PCB board to the external circuit. Both the cover plate and the adsorption structure are located at the opening, and the cover plate is rotatably connected to the opening, allowing the cover plate to rotate relative to the opening. The adsorption structure is fixedly connected to the opening. Since the cover plate is made of metal and the adsorption structure is magnetic, it has a first position and a second position during the rotation of the cover plate. When the cover plate is in the first position, the opening is open. When the cover plate is in the second position, the inner side of the cover plate and the adsorption structure are magnetically attracted together, thus blocking the opening. This allows for quick opening and closing of the opening, making the operation simple and convenient. Attached Figure Description

[0019] refer to Figure 1 and Figure 2 An embodiment of this application provides a protective structure for an exposed PCB port, comprising a housing 1, a cover plate 3, and an adsorption structure. The housing 1 has an opening area opposite to the PCB port, and the opening area is provided with an opening. The cover plate 3 and the adsorption structure are both located at the opening area, and one side of the cover plate 3 is rotatably connected to the portion of the housing 1 opposite to the opening area. The cover plate 3 is at least partially made of metal, and the adsorption structure is at least partially magnetic. The cover plate 3 has a first position and a second position during rotation. When the cover plate 3 is in the first position, the opening is open. When the cover plate 3 is in the second position, the metal part of the cover plate 3 is opposite to the magnetic part of the adsorption structure, and the cover plate 3 blocks the opening.
[0020] In this embodiment, a PCB board is placed inside the outer casing 1. The opening in the opening area of the outer casing 1 is opposite to the PCB board, facilitating the connection of the end of the PCB board to external circuitry. Both the cover plate 3 and the adsorption structure are positioned at the opening. The cover plate 3 is rotatably connected to the opening, allowing it to rotate relative to the opening. The adsorption structure is fixedly connected to the opening. Since the cover plate 3 is made of metal and the adsorption structure is magnetic, the cover plate 3 has a first position and a second position during rotation. When the cover plate 3 is in the first position, the opening is open. When the cover plate 3 is in the second position, the inner surface of the cover plate 3 is magnetically attracted to the adsorption structure, thus blocking the opening. This allows for rapid opening and closing of the opening, making the operation simple and convenient.
[0021] In some embodiments, the adsorption structure includes a baffle 4 and a magnetic element 2; one side of the baffle 4 and the cover plate 3 are respectively disposed on opposite inner sides of the opening, and the surface area of the baffle 4 is smaller than the size of the opening; the magnetic element 2 is disposed on the outer side of the baffle 4, and when the cover plate 3 is in the second position, the magnetic element 2 is magnetically connected to the inner side of the cover plate 3.
[0022] In this embodiment, the adsorption structure comprises two parts: a baffle 4 and a magnetic component 2. One side of the baffle 4 and the cover plate 3 are respectively disposed on opposite inner sides of the opening, and the surface area of the baffle 4 is smaller than the size of the opening. Further, the opening is rectangular in shape. The baffle 4 includes a main body and two receiving parts. The main body is disposed on the inner side of the opening; the two receiving parts are located at both ends of the main body and are disposed on the inner sides of both ends of the opening, allowing the PCB board port to be exposed when the opening is open. The magnetic component 2 is disposed on the outer side of the baffle 4, and when the cover plate 3 is in the second position, the magnetic component 2 is magnetically connected to the inner side of the cover plate 3. Adhesive is provided on the surface of the magnetic component 2, allowing it to be adhered to the outer surface of the baffle 4.
[0023] In some embodiments, the magnetic element 2 has a set strength of magnetism; wherein the range of the adsorption force provided by the set strength of magnetism is: greater than a first separation force and less than a second separation force, the first separation force being an accidental separation force that causes the cover plate 3 to open, and the second separation force being an active separation force that causes the cover plate 3 to open. In this embodiment, multiple magnetic components 2 are provided and are evenly spaced on the outer side of the main body; two receiving parts are symmetrically arranged at both ends of the main body, and their extension direction is perpendicular to the extension direction of the main body. The magnetic force provided by all magnetic components 2 is greater than the first separation force and less than the second separation force. The first separation force is the unexpected separation force that causes the cover plate 3 to open, such as the force caused by external disturbances like vibration. The second separation force is the active separation force that causes the cover plate 3 to open, the force applied by the operator to actively open the cover plate 3. This ensures that the cover plate 3 will not open accidentally due to external disturbances, and also avoids the situation where the operator cannot open it due to the large magnetism.
[0024] In some embodiments, the cover plate 3 has a rectangular shape. When the cover plate 3 is in the second position, it covers the magnetic element 2. The distance between the outer surface of the magnetic element 2 and the outer surface of the opening is equal to the thickness of the cover plate 3, ensuring that the outer surface of the cover plate 3 is flush with the outer surface of the outer shell 1 when the opening is closed.
[0025] In some embodiments, the inner sides of both ends of the opening are provided with a rotating shaft 5, and the cover plate 3 has a corresponding connecting hole for the rotating shaft 5. The rotating shaft 5 extends into the corresponding connecting hole so that the cover plate 3 and the rotating shaft 5 are rotatably connected. A notch is provided on the side of the cover plate 3 away from the connecting hole, so that the operator can easily open the cover plate 3 through the notch when opening the cover plate 3.
[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
