ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector having a pair of solder pads for surface mounting to a printed circuit board, and particularly to solder pads which have a positioning tab for preventing the connector from moving in a vertical direction.
Prior art U.S. Pat. Nos. 5,044,988, 4,713,013 and 4,850,892 disclose electrical connectors having posts integrally formed with the connector housing, and extending from the bottom surface of the housing. The designs disclosed in U.S. Pat. Nos. 4,681,389 and 4,907,987 and other recent patents replaced the integral posts, which had insufficient resiliency with resilient metallic posts which are assembled separately into the housing for retaining the connector on the board. A disadvantage of this connector is that it has insufficient holding strength to secure the connector on a printed circuit board when a vertical upward force is applied to the connector.
Hence, an improved solder pad for surface mounted electrical connectors is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide an electrical connector having an improved solder pad for surface mounting the electrical connector to a circuit board, the solder pad being capable of securing the connector from moving in the upright direction.
To fulfill the above mentioned objective, a surface mounted electrical connector in accordance with the present invention comprises an elongated insulative housing defining a holding cavity at either side thereof, a slot define in a side wall of the holding cavity, and a securing channel extending through the housing from the holding cavity to a rear face of the housing. A plurality of terminals are secured in the insulative housing. Each of the pair of solder pads includes a vertical retaining portion for securely engaging with the holding cavity and a horizontal solder portion extending from the lower edge of the retaining portion for soldering to the printed circuit board. Additionally, the retaining portion further includes a positioning tab extending from the upper front edge of the retaining portion for securely engaging with the slot of the insulative housing, and a securing portion extending from a rear edge of the retaining portion for engagingly securing within the corresponding securing channel.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
