Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the described upper and lower directions are determined by the upper and lower positions of each component in the plastic module, i.e. the directions opposite to the directions shown in the drawings.

Fig. 1 and 2 are schematic structural diagrams of a plastic module according to an embodiment of the present invention. As shown in fig. 1 and fig. 2, in an embodiment of the present invention, a conducting structure for a plastic module is provided, the plastic module may include a plastic housing and a printed circuit board PCBA100 disposed in the plastic housing, the conducting structure may include:

a lead-through 110;

connecting piece 120 for fixing PCBA100 and lower housing 140 of the plastic housing and for conducting PCBA100 and conducting piece 110;

and a fixing member 130 for fixing the lower case 140 and the mounting bracket 200 and fixing the conductive member 110 and the mounting bracket 200.

Of course, to achieve ground conduction for the PCBA, the conductive member 110, the connecting member 120, and the fixing member 130 are made of conductive materials, such as metal materials.

The conductive member 100 has one end connected to the connecting member 120 and the other end connected to the fixing member 130. On the basis of only increasing one and leading to piece 110, through the position of rationally setting up connecting piece 120 and mounting 130 for originally being used for being fixed in PCBA100 the connecting piece 120 of plastic casing can also be used for realizing PCBA100 and leading to of piece 110 simultaneously, originally be used for being fixed in plastic casing even mounting 130 can also be used for realizing leading to of piece 110 and installing support 200 simultaneously.

In order to perform the fixing and conducting functions, the connecting member 120 and the fixing member 130 may be, for example, metal screws. The conductive member 110 may be a metal spring, for example.

Although the mounting bracket is mostly made of metal materials, the surface of the mounting bracket is mostly subjected to insulation treatment, so that the metal layer of the mounting bracket is not exposed on the surface. The fixing member 130 is electrically connected to the mounting bracket 200 through a metal nut provided on the mounting bracket 200 to connect the conductive member 110 to the mounting bracket 200.

In an alternative embodiment of the present invention, the mounting bracket is not surface-treated, and the switch-on of the switch-on member 110 and the mounting bracket 200 can be directly realized by the switch-on member 110 contacting with the mounting bracket 200. In this embodiment, after being assembled, the conducting member 110 may be slightly higher than the bottom surface of the upper housing of the plastic housing, for example, to ensure the conduction between the conducting member 110 and the mounting bracket 200. Of course, in this case, the fixing member 130 only needs to realize the connection between the lower housing 140 and the mounting bracket 200, and may be disposed at any position where the connection can be realized, without contacting with the other end of the conductive member 110.

The utility model also provides a plastic module, this plastic module can include:

a plastic housing including an upper case 150 and a lower case 140;

a PCBA100 disposed between the upper housing 150 and the lower housing 140; and
