Technical Field
[0001] This utility model relates to the field of infrared touch frame technology, and in particular to an infrared touch frame that is compatible with various PCBA boards. Background Technology
[0002] With the continuous development and diversification of electronic devices, touch screen technology is increasingly widely used in various devices. Infrared touch screens, as a mature and widely applied technology, are widely used in various applications due to their advantages such as low cost, fast response speed, and immunity to screen surface contamination. However, with the upgrading of electronic devices and the continuous enrichment of their functions, the specifications and dimensions of PCBAs (Printed Circuit Board Assemblies) have become increasingly diverse.
[0003] Traditional infrared touch frames are typically designed to fit only fixed-size PCBA boards, resulting in poor compatibility with PCBA boards of different specifications and failing to meet diverse market demands. Therefore, we propose an infrared touch frame compatible with multiple PCBA board sizes to address these technical problems. Utility Model Content
[0004] The purpose of this invention is to provide an infrared touch frame that is compatible with various PCBA board specifications, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a front frame, a rear frame, and a PCBA board. A storage box is provided at the bottom of the front frame and the rear frame. A limiting plate is fixedly provided on the inner side of the storage box. Multiple limiting slots are opened on the limiting plate. A connecting rod is inserted into the limiting slot. A connecting post is fixedly provided on the inner side of the storage box through the connecting rod. A fastening nut is threaded on the connecting rod and located on the outer side of the limiting plate.
[0006] As a preferred embodiment, the bottom of the storage box is provided with evenly spaced ventilation holes, and end caps are snapped onto both sides of the storage box.
[0007] As a preferred embodiment, the storage box is provided with a snap-fit cover, and a snap-fit strip is fixedly provided on the inner side of the snap-fit cover. A snap-fit protrusion is fixedly provided on the snap-fit strip on the side closest to the storage box.
[0008] As a preferred embodiment, the connecting post is connected to the PCBA board.
[0009] As a preferred embodiment, a reserved slot is provided on the opposite side of the front frame and the rear frame, and a fixing slot is provided through the front frame and the rear frame, with a fixing plate inserted into the inner side of the fixing slot.
[0010] As a preferred embodiment, the storage box is provided with a snap-fit cover, and a cable tie box is fixedly installed on the inner side of the snap-fit cover.
[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are: This device allows for the loading of PCBA boards of different widths by adjusting the tilt angle inside the storage box. A connecting rod inserted into the limiting slot is used to load the connecting post. The connecting post, which extends from the connecting rod and is fixed inside the storage box, clamps the PCBA board. A fastening nut, threaded onto the connecting rod and located on the outside of the limiting plate, limits the connecting rod, facilitating the fixation of the PCBA board inside the storage box. When the width of the PCBA board exceeds the height inside the storage box, the connecting rod is moved horizontally relative to the limiting slot, causing the PCBA board to tilt and be placed inside the storage box, thus completing the loading process.
