Grounding structure of pcb electrical connector module

Abstract

The invention discloses a PCB electric connector module grounding structure, comprising a module housing and a track with a U-shaped central section, wherein the module housing is clamped and fixed to the track. A PCB and an electric connector are positioned in the housing module, wherein the electric connector is positioned between the PCB and the track, and comprises at least one plastic body; an upper portion of each plastic in a width direction is accommodated between two sidewalls of the track; at least one side of each plastic body is fixedly provided with a conductive metal grounding terminal; the metal grounding terminals is located between a side of the plastic body and a sidewall of the track. One end of the metal grounding terminal is in fixed connection with the PCB, and the other end is in elastic contact with the sidewall of the track. The PCB electric connector module grounding structure can effectively meet the grounding requirement of a PCB electric connector module, simplify grounding terminal structures and a whole structure of the PCB electric connector module, reduce assembling steps, facilitate assembling, and accomplish the purposes of increasing material utilization rate and lowering production cost.

Description

technical field [0001] The invention relates to a grounding structure of a module, in particular to a grounding structure of a PCB electrical connector module. Background technique [0002] Module products are widely used in liquid crystal display and backlight and other fields. Module products usually require a specific grounding structure to protect the module circuit from interference signals and avoid confusion in the entire module circuit. There are two main grounding methods for existing PCB electrical connector modules, one is to realize grounding through the electrical connector connecting wires welded on the PCB board in the module, and the other is to connect the wires in the module through metal grounding terminals. The PCB board and track to achieve the purpose of grounding. However, when the PCB module is grounded by connecting wires through the electrical connector, the grounding of the electrical connector is cumbersome, and both the input part and the ground...

Problems solved by technology

However, when the grounding of the PCB module is realized by connecting the wires through the electrical connector, the grounding of the electrical connector is cumbersome, and both the input part and the grounding part need to be connected to the wires, which is easy to connect to the wrong position, and there is a risk

When the PCB module is grounded through the metal grounding terminal, the existing metal grounding terminal is usually a separate piece, and the connection between the metal grounding terminal and the PCB board and the track is a clip-type structure, which has many bends and a complicated structure. Mold processing is difficult, more materials are used, material utilization rate is lower, and cost is higher

In addition, when the metal ground terminal in the prior art is assembled, one end of the ground terminal is clamped on the PCB board and the other end is clamped on the track by being engaged in the corresponding groove of the module housing, so the ground terminal is prone to shake, The stability is poor, and the ground terminal is a separate piece, and the assembly procedure is complicated
