Description

Technical Field

[0001] The utility model belongs to the technical field of test equipment, and particularly relates to a general-purpose product test box. Background Art

[0002] A test fixture is a mechanical auxiliary device used to test semi-finished products / finished products or a certain process in the production process, aiming to determine whether the object under test meets the purpose of the initial designer. Therefore, it is widely used in fields such as analog, digital, memory, RF, and power circuits, and a corresponding functional test fixture is required for each form.

[0003] In conventional test fixtures, the product slots for placing products are customized for a certain model of product, resulting in that the entire set of test equipment can only be used to test this model of product. For enterprises with products of the same function but different models, as the number of product models increases, the test cost also increases accordingly. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a general-purpose product test box to solve the technical defects described in the background art.

[0005] The general-purpose product test box includes a bottom shell. A control panel is installed inside the bottom shell. A support edge is provided around the top of the bottom shell. The support edge is made of iron. A working cover plate is placed on the support edge. A magnet for adsorbing the iron is provided around the bottom of the working cover plate. A product position and a test wiring harness are arranged on the upper surface of the working cover plate. The product position is used to place the product to be tested. A flip cover for pressing and fixing the product under test is arranged on the side of the product position. The test wiring harness is used to electrically connect the product under test to the control panel.

[0006] According to the above technical solution, the utility model realizes the following beneficial effects:

[0007] 1. Since the working cover plate is installed on the bottom shell through the cooperation of the magnet and the iron, the working cover plate can be conveniently disassembled from the bottom shell to replace the working cover plate suitable for another model of product, so that it is not necessary to manufacture multiple sets of test fixtures according to different sizes or models of products, thereby reducing the test cost;

[0008] 2. Since the combination of the bottom shell and the working cover plate, and the cooperation of the flip cover and the product position are adopted, it is not necessary to set any mechanical power module, so that the general-purpose product test box has a simple structure, is convenient to carry and is convenient to move on the production line workstations;

[0009] 3. Since the working cover plate can be separated from the bottom shell, it is convenient to disassemble and maintain the devices installed in the shell later.

[0010] To further optimize the above technical solution, one or more of the following embodiments can be optionally combined without conflict.

[0011] In some embodiments, the control panel is provided with a socket, and the working cover plate is provided with an avoidance slot hole above the socket. The test wiring passes through the avoidance slot hole and is plugged into the control panel.

[0012] According to the above technical solution, during the process of testing the product, it is possible to electrically connect by plugging the wiring through the working panel to the socket inside the bottom case, so as to facilitate the electrical connection between the control panel and the peripheral device, facilitate the electrical connection between the control panel and the product under test, and facilitate the electrical connection between the control panel and a certain contact point of the product under test using the wiring.

[0013] In some embodiments, the control panel is provided with a sliding groove, the avoidance slot hole is located inside the sliding groove, and a sliding plate that can move to cover above the avoidance slot hole or move away from above the avoidance slot hole is slidable inside the sliding groove. Limit plates for restricting the sliding plate from detaching from the sliding groove are installed on both sides of the sliding groove.

[0014] According to the above technical solution, when the socket is not needed, the avoidance slot hole can be closed, thereby preventing foreign objects from falling into the lower bottom case and causing damage to the internal components.

[0015] In some embodiments, the flip cover is provided with a hook for locking the working cover plate.

[0016] According to the above technical solution, when the flip cover is flipped down and pressed against the product, one side of the flip cover can be fixed by the hook, so as to more stably prevent the product from shifting.

[0017] In some embodiments, the flip cover is mounted with a heat dissipation block through an equal-height screw. One side surface of the heat dissipation block is used to contact the product, the other side surface of the heat dissipation block penetrates to the top of the flip cover, and a spring is provided between the heat dissipation block and the flip cover.

[0018] According to the above technical solution, after the flip cover is flipped down and pressed against the product, the heat generated after the product is powered on can be guided outside the flip cover, so as to avoid heat accumulation on the contact surface between the flip cover and the product and cause damage to the product.

[0019] In some embodiments, the bottom case is installed with a power control board and a data transmission interface that are electrically connected to the control panel.

[0020] According to the above technical solution, when moving the universal product test box, the power consumption requirements can be met, thereby further improving the convenience of carrying and moving the universal product test box.

[0021] In some embodiments, the bottom case is provided with conductive contacts, and the bottom of the working cover plate is provided with conductive antennae for contacting the conductive contacts.

[0022] According to the above technical solution, when the working cover plate is placed on the bottom case, the conductive antenna contacts the conductive contact, thereby improving the convenience of the electrical connection between the product under test and the control panel.
