ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of connection mechanisms for connecting to a printed wiring board (PWB).
BACKGROUND OF THE INVENTION
PWB's are used in a wide variety of electronic devices. Various types of connectors can be mounted on PWB's to transfer electronic signals to and from the PWB. Depending on the particular circumstances involved, surface mount connectors can provide well known advantages over other types of connectors, such as lower cost, manufacturing efficiencies and increased component density. The surface mount connector mechanism of the present invention can be used in any application utilizing a PWB. The present invention can also be used to implement various different types of surface mount connectors, having a variety of sizes, shapes, pin configurations and other characteristics. The preferred embodiment of the present invention is described in terms of a telephone application, including descriptions of several different types of surface mount connectors and a surface mount PWB interconnection mechanism.
SUMMARY OF THE INVENTION
A surface mount connector of the present invention can be mounted on either a first side or a second side of a PWB. The connector provides access at the first side of the PWB whether it is mounted on the first side or the second side. If the connector is to be mounted on the first side, the PWB has one or more pads on the first side. If the connector is to be mounted on the second side, the PWB has one or more pads on the second side and the PWB defines an opening through the PWB. The connector comprises a connector body having a length, a width and a height one or more signal leads. The length and width of the connector body have smaller dimensions than the opening in the PWB. The signal leads extend beyond the dimensions of the opening in the PWB. If the connector is mounted on the first side, the connector is placed on the first side so that the leads contact the pads. If the connector is mounted on the second side, the connector is placed partially through the opening from the second side so that the leads contact the pads.
The present invention also encompasses a method of mounting a connector on a PWB. The method of mounting the connector provides access to the connector from a first side of the PWB. The PWB also has an opposite side and at least one signal pad. The connector also has at least one signal lead. The method comprises the following steps. If the connector is to be mounted on the first side, the connector is placed on the first side with the signal leads of the connector making contact with the signal pads of the PWB, the signal pads of the PWB being on the first side. If the connector is to be mounted on the opposite side, the connector is placed through an opening in the PWB from the opposite side through to the first side with the signal leads of the connector making contact with the signal pads of the PWB, the signal pads of the PWB being on the opposite side. Lastly, the signal leads of the connector are secured to the signal pads of the PWB.
