Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth modules, in particular to a waterproof structure of a Bluetooth module. Background Art

[0002] A Bluetooth module is a PCBA board with integrated Bluetooth function, which is used for short-range wireless communication. It is generally composed of a Bluetooth chip integrated on a PCB board, an onboard antenna, a wiring port, and a shielding cover connected to the outside of the Bluetooth chip.

[0003] In order to shield external interference sources and meet waterproof requirements, the existing Bluetooth module adds a shielding cover on the surface of the Bluetooth module. The shielding cover is usually fixed to the surface of the circuit board by glue. When removing it, it needs to be heated by a hot air gun to remove the shielding cover. However, since the hot air gun needs to melt the glue through heat conduction before the shielding cover can be removed, it is more troublesome to remove the shielding cover. At the same time, there is no gap between the bottom of the shielding cover and the circuit board, which makes it difficult to lift the shielding cover to heat it, resulting in a long time to remove the shielding cover. Therefore, a waterproof structure of a Bluetooth module is proposed to solve the above problems. Utility Model Content

[0004] The utility model provides a waterproof structure of a Bluetooth module, which solves the above technical problems.

[0005] In order to solve the above technical problems, the utility model provides a waterproof structure of a Bluetooth module, including a shielding cover, a connecting strip is connected in the middle of the shielding cover, an insulating rubber strip is bonded to the surface of the connecting strip, an upper sealing strip is fixed to the bottom of the shielding cover, a lower sealing strip is bonded to the surface of the upper sealing strip, and a Bluetooth module is arranged in the middle of the shielding cover.

[0006] Preferably, the lower end of the lower sealing strip is connected to a circuit board, and the lower sealing strip is provided with two layers, an inner layer and an outer layer.

[0007] Preferably, an outward expansion structure is provided at the upper end of the upper sealing strip and the surface contour of the lower sealing strip is in contact with the surface of the upper sealing strip.

[0008] Preferably, the thickness of the connecting strip is half of that of the shielding cover, and a partition groove is provided in the middle of the connecting strip.

[0009] Compared with the related art, the waterproof structure of a Bluetooth module provided by the utility model has the following beneficial effects:

[0010] The utility model adds a connecting strip on the surface of the shielding cover so that the shielding cover can be disconnected from the middle, which is convenient for removing the shielding cover. The shielding cover can also be removed when a hot air gun is not used, making the maintenance of the Bluetooth module more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
