The structure of the electronic product is precise, and sealing designs such as waterproof and dustproof are generally needed. The sealant filling is a common sealing method, and at present, the following sealant filling modes are mainly adopted:
(1) The structural member is rigidly matched with the circuit board, and glue is filled through glue filling holes in the circuit board. However, the sealant has high fluidity and high sealant leakage probability, and the sealant easily flows to the window area to influence the use of electronic devices in the window area, so that the yield of products is reduced. In addition, the structural member and the circuit board are directly rigidly matched, so that the requirement on the matching precision is high, and the production cost is increased.
(2) The structural member is matched with the circuit board in a clamping groove mode, and a large-area metalized surface and a metalized groove are required to be arranged on the circuit board to be matched with the bulge on the structural member. However, the metallized grooves are not beneficial to the wiring layout of the circuit board, and the large-area metallization increases the production cost.
(3) The bulges on the structural part and the circuit board are in sealing fit through dispensing of 0.5mm, but the thickness of dispensing is uncontrollable, and the centering degree of the terminal after being mounted can be influenced. And the dispensing is difficult to realize, and the cost is increased by using the high-protection high-temperature-resistant 3M back adhesive.
The above glue filling modes can either flow the sealant to the position where the glue filling is not needed or increase the cost to prevent the sealant from flowing to the position where the glue filling is not needed.
Therefore, the embodiment of the utility model provides the electronic equipment, the arranged sealing sleeve is used for sealing and connecting the circuit board and the supporting frame, so that the sealant is prevented from flowing into the window cavity from the gap between the circuit board and the supporting frame, the normal use of electronic devices in the window cavity is further ensured, and the yield of products is improved.
