Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning structure technology, specifically a positioning structure for conductive rubber and PCB. Background Technology
[0002] Conductive rubber is typically made of silicone rubber or synthetic rubber substrate, with conductive particles such as carbon black and metal powder uniformly dispersed inside. Its key structure contains multiple conductive channels and insulating layers. This partitioned structure makes it conductive in a specific vertical direction and insulating in the lateral direction. The core of a PCB (printed circuit board) is a non-conductive substrate with a thin layer of copper foil adhered to its surface. During manufacturing, the copper foil is made into the required circuit traces and pads through photolithography and etching. A solder mask layer covers the circuit surface, exposing only the pads that need to be soldered. A silkscreen layer is used to mark the position and orientation of components. Metallized vias / through holes connect copper lines in different layers. Multilayer PCBs are made by laminating and bonding multiple core boards containing inner layer circuits.
[0003] However, existing conductive rubber and PCB product structures generally consist of a housing, conductive rubber, PCB, and a bottom cover. The structural fit involves fixing the conductive rubber to the housing, then fixing the PCB, and finally attaching the bottom cover. This requires precise control of the dimensions of the housing, conductive rubber, and PCB, resulting in excessive management and potential errors that could lead to malfunctions. Some traditional fixing structures have unidirectional fixing mechanisms, but these can result in uneven adhesion between the conductive rubber, PCB, and bottom cover, leading to insufficient contact in the assembled product. Therefore, those skilled in the art have provided a positioning structure for conductive rubber and PCB to address the problems mentioned in the background section. Utility Model Content

[0027] The working principle of this utility model is as follows: This device is equipped with an assembly mechanism 4. During assembly, a bottom cover fastening block 9 is added to the bottom cover body 2. The bottom cover fastening block 9 is used for four-way positioning. A conductive rubber fastening block 7 and a fastening connecting block 8 are added to the conductive rubber body 6 for four-way positioning. By assembling and positioning the bottom cover fastening block 9 on the outside of the bottom cover body 2 and the fastening connecting block 8 on the outside of the conductive rubber body 6, the bottom cover body 2, the PCB board, and the conductive rubber body 6 can be fixed in their vertical positions, making the assembly structure stable and reducing assembly errors.
