The development of computer network provides a more convenient and comfortable living environment for human beings.

Therefore, today's Internet continues to develop rapidly, and the technology of using the network to transmit is also getting more and more advanced. A computer system consisting of only a few computers or devices is no longer sufficient. The computer system used by general companies is no longer just composed of several computers, but is composed of computers or equipment scattered in different places connected through the network to provide various business processing and information query. Serve. And the general user's personal computer, or notebook computer, even palmtop computer, also all has the function and the interface that have access to the Internet.

Most of these computer devices connected to each other via a network need to use a connector (Connector) to connect with the network or related electronic devices. Connectors traditionally used to connect with network-related devices generally use RJ-45 connectors (Jack) and connectors (Plug) for coupling. The standard RJ-45 connection seat and connection head must have the ability to exchange each other, therefore, its appearance size and internal connection size have certain requirements.

For the ever-growing demand for network transmission, the demand for RJ-45 connectors is also increasing. For example, the density of RJ-45 connectors used on hubs (Hub) is also getting higher and higher.

Existing electrical connector manufacturers use insert molding to fix the RJ terminals with plastic, but due to the limitation of the bending structure of the existing RJ terminals, the welding position between the RJ terminals and the PCB board is located in the center of the PCB board. After the RJ terminal is welded to the PCB board, the placement space of the filter module located below the electrical module is limited, so that the installation space of the filter module is limited, and sufficient electronic components cannot be placed, while the upper part of the electrical module is vacant. Phenomenon, the space inside the electrical connector is not fully utilized, the structure is not compact enough, and the overall volume of the electrical connector is too large.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: a PCB welding structure of an electrical connector, including a housing body and an electrical module located in the housing body, and the electrical module includes a filter module located in the housing body and respectively The upper row of PCB boards and the lower row of PCB boards arranged on both sides of the filter module, the front of the filter module is provided with a terminal base and the RJ terminal arranged on the terminal base, and the upper row of PCB boards and the lower row of PCB boards are set There is an extension part, and the extension part is provided with a plurality of welding holes; one end of the RJ terminal passes through the side of the terminal base and is welded to the welding holes one by one.

Wherein, the extensions on the upper row of PCBs are integrally formed with the upper row of PCBs, and the extensions on the lower row of PCBs are integrally formed with the lower row of PCBs.

Wherein, the welding holes on the upper row of PCB boards are located at the upper part of the extension part of the upper row of PCB boards.

Wherein, the welding holes on the lower row of PCB boards are located at the lower part of the extension part of the lower row of PCB boards.

Wherein, the RJ terminal and the terminal base are processed by insert molding.

The beneficial effect of the utility model is that: the utility model provides a PCB welding structure of the electrical connector. Due to the setting of the extension part, the welding between the RJ terminal and the middle part of the upper row of PCB boards or the lower row of PCB boards is avoided. The position between the first row of PCB boards and the lower row of PCB boards frees up more space, and facilitates more compact accommodation of the filter module and the electrical module in the space between the upper row of PCB boards and the lower row of PCB boards. The utility model effectively improves the space utilization rate inside the electric connector, and frees up installation space for other electronic components, so as to accommodate more electronic components, has a compact structure, and the volume of the electric connector is smaller.
