The technical problems to be solved by the utility model are realized by adopting the following technical scheme:
the utility model provides a novel PCB waterproof construction, includes filling body, circuit board, pencil and casing, filling body fills in the casing, the circuit board parcel is in filling body, the one end and the circuit board of pencil are connected, and the other end extends the casing.
As a preferred example, the inner wall of the housing is provided with support ribs for supporting and defining the placement position of the circuit board.
As a preferred example, a plurality of ear seats are arranged on the outer side of the shell.
As a preferred example, a wire clamping block is also included for fixing and guiding out the wire harness.
As a preferred example, a notch is formed at the upper edge of the side wall of the shell, and a clamping groove corresponding to the notch is formed in the side wall of the wire clamping block.
The beneficial effects of the utility model are as follows: according to the utility model, through the arrangement of the filling body and the shell, the electrical element is directly wrapped in the filling body, so that the waterproof effect is better and the sealing service life is long compared with the traditional rubber pad.
Drawings
FIG. 1 is a schematic diagram of an explosive structure of the present utility model;
fig. 2 is a schematic cross-sectional structure of the present utility model.
In the figure: the device comprises an encapsulating body 1, a circuit board 2, a shell 3 and a wire clamping block 4.
Description of the embodiments
The utility model will be further described with reference to the following detailed drawings, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in fig. 1-2, a novel PCB waterproof structure includes a potting body 1, a circuit board 2, a wire harness 5, and a housing 3. The shell 3 is made of plastic material, and the inner wall of the shell is provided with supporting ribs for supporting and limiting the placement position of the circuit board 2, and is used for positioning the circuit board 2, filling the carrier of the colloid 1 and the main body of the module; the filling body 1 is filled in the shell 3 and is a main sealing medium, and fills the inner space and gaps of the shell 3 in a flowing state (the sealing medium is not fully disclosed here, and a specific type or model is best described); the circuit board 2 is a module electronic control unit, the whole package is in the encapsulating body 1, one end of the wire harness 5 is connected with the circuit board 2, the other end extends out of the shell 3, and the circuit board 2 is connected with external equipment through the wire harness 5.
Further, a plurality of ear seats are arranged on the outer side of the shell 3, so that the waterproof structure module is convenient to install. The wire clamping block 4 is further arranged and used for fixing and guiding out the wire harness 5, specifically, a notch is formed in the upper edge of the side wall of the shell 3, a clamping groove corresponding to the notch is formed in the side wall of the wire clamping block 4, the wire clamping block 4 is clamped at the notch, and the wire harness 5 passes through the wire clamping block 4 to be guided out.
The waterproof structure is used on a component of the vehicle-mounted Bluetooth auxiliary module, and the common sealing structure (rubber pad and the like) cannot meet the severe waterproof requirement due to the exposure of the installation position, so that various problems are well solved by the mode of sealing the PCB by glue filling in the shell.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be appreciated by persons skilled in the art that the present utility model is not limited to the embodiments described above, but is capable of numerous variations and modifications without departing from the spirit and scope of the utility model as hereinafter claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
