Description

Technical Field

[0001] This utility model relates to the field of circuit board test bracket technology, specifically to a movable multi-circuit board test bracket. Background Technology

[0002] Currently, there are two main types of board testing brackets: one for fixing a single board, where the power supply depends on an external power source and the bracket itself cannot move; and another for fixing multiple boards (2-4 boards), where the bracket itself cannot move, the power supply depends on an external power source, and all network cables need to be pulled from the outside, resulting in messy cabling.

[0003] As can be seen from the above, the existing circuit board brackets have the following pain points that need to be addressed:

[0004] 1. The number of testable boards is small, resulting in low efficiency;

[0005] 2. The stand is immovable, limiting the testing environment;

[0006] 3. Both network cables and power cables need to be connected from the outside, resulting in messy wiring;

[0007] 4. No heat dissipation function. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a movable multi-board test bracket with a simple structure, safe and reliable, which can test multiple boards at the same time, greatly improving the board testing efficiency. It only requires one 220V power cord and one network cable to be connected, reducing the number of external cables and avoiding messy wiring. Casters are installed at the bottom of the bracket, so the bracket can be moved easily and is not limited to fixed positions and temperature and humidity environments for testing.

[0009] To address the aforementioned technical problems, this utility model provides a movable multi-board test bracket, comprising a movable bracket with guide rails on both sides, boards disposed between the guide rails, and a fan assembly disposed on the outer side of the guide rails on the movable bracket; an electrical assembly disposed at the bottom of the movable bracket; and four supporting profiles, some of which are provided with limiting sheet metal.

[0010] Furthermore, the fan assembly is fixed to both sides of the movable bracket by screws.

[0011] Furthermore, the support profile is provided with fixing holes at intervals to accommodate the network cables and power cables required by the board.

[0012] Furthermore, the limiting sheet metal is provided with positioning holes to adapt to the PCB board that is inserted on the outside.

[0013] Furthermore, casters are provided around the bottom of the movable support.

[0014] The beneficial effects of this invention are as follows: This device can test multiple circuit boards simultaneously, which greatly improves the efficiency of circuit board testing. It only requires one 220V power cord and one network cable for connection, reducing the number of external cables and avoiding messy wiring. Casters are installed at the bottom of the bracket, which can be moved easily and is not limited to fixed positions and temperature and humidity environments for testing. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
