Description

A laminated electrical connector

technical field

The invention relates to the technical field of electrical connection, and in particular provides a laminated electrical connector.

Background technique

Electrical connectors configured to PCB boards are typically used for connection between two electronic devices. In order to ensure an effective electrical connection between electronic devices, an indicator light (such as an LED) may be provided on a PCB board or an electrical connector. LED indication can not only provide lighting, but more importantly, it can be used as a visual signal for users to understand the signal passing, power indication, or error indication during signal transmission between two connected electronic devices.

In order to miniaturize the electrical connector and effectively save the space occupied between components, a light component for transmitting LED light has been integrated into the connector component. Earlier (March 2, 1999) U.S. Patent Publication No. 5,876,239 titled a modular jack-socket connector having a light pipe for switching from the input face of the light pipe along the mating face of the modular jack-socket. Optical signals are transmitted through the output face of the light pipe. However, there are some problems with reference to this type of electrical connector, because the terminal block of this type of electrical connector is usually packaged from the rear. Packaging such connectors necessitates alignment of the front receptacle with the socket of the rear terminal block. Tail alignment increases the overall size of the connector and increases the PCB area occupied by the connector.

Small form factor connectors are usually inserted into the shield through the bottom opening. When dual connectors are required to be stacked, that is, intended to be integrated with two modules in a vertically spaced arrangement, the relevant connector assembly cannot actually be inserted into the shield through the bottom opening due to the intermediate cover in the middle of the shield. in the hood.
