Description

Laminated electric connector

Technical Field

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

Background

Electrical connectors configured to a PCB board are commonly used in connections between two electronic devices. To ensure an effective electrical connection between the electronic devices, indicator lights (e.g., LEDs) may be provided in the PCB board or the electrical connector. LED indicators not only provide illumination, but more importantly can serve as a visual signal to the user and allow the user to know the signal passing between two connected electronic devices, a power indication, or an indication of an error occurring during the transmission of the signal.

In order to miniaturize the electrical connector and to effectively save the inter-module footprint, optical modules for transmitting LED light have been integrated into the connector module. Early (3/2/1999) U.S. patent publication No. 5876239 entitled modular jack socket connector has a light pipe for transmitting an optical signal from an input face of the light pipe through an output face of the light pipe along a mating face of the modular jack socket. However, there are problems with reference to this type of electrical connector because the termination modules of such connectors are typically tail-packaged. Packaging such connectors requires front-end jacks to align with the slots of the tail termination modules. Tail alignment increases the overall size of the connector and also increases the PCB board area occupied by the connector.

Small size connectors are typically inserted into the shield through the bottom opening. When a stacked arrangement of dual connectors is required, i.e. intended to be integrated with two modules in a vertically spaced arrangement, the associated connector assembly cannot in fact be inserted into the shielding cage through the bottom opening due to the intermediate cage provided in the middle of the shielding cage.

The present invention is therefore directed to developing a new laminated electrical connector having features that overcome the above-mentioned drawbacks and that are easily mated with a shield can.
