An electrical connector comprises a generally rectangular dielectric housing with a mating face and a mounting face. A plurality of terminal support posts extend in a direction from the mounting face towards the mating face and each support post has oppositely facing first and second sidewalls and a connecting surface. A plurality of terminal receiving cavities are spaced along a longitudinal axis of the housing for receiving terminals therein. A plurality of terminals are provided with each including a solder tail portion and a generally U-shaped contact portion. The solder tail portion is positioned along the mounting face and the contact portion includes a first, distal contact leg, a second, proximal contact leg spaced from and generally parallel to the first contact leg and a connecting portion extending between the first and second contact legs. The first contact leg extends along the first sidewall, the second contact leg extending along the second sidewall, and the connecting portion extending along the connecting surface.

A board mounted connector for a board to board connector system is disclosed which can be smaller, provide a more robust connection to a conductive circuit on a printed circuit board while allowing for a high degree of circuit design freedom on the board circuit due to the terminal insertion from the mating side of the housing where the terminals are generally above a bottom portion () of the non-conductive housing () adjacent the board. The housing () is provided with fitting holes () extending from an end surface () on the side which mates with the male housing (). The female terminals () have anchor portions () to be fitted into the fitting holes () of the female housing () and contact portions () to engage terminals in a mating connector. Forward end portions () of the anchor portions () are soldered to a circuit terminal of the board (). Cut out portions () in the rectangular frame portion () allow for the solder joint between the end portion () and the conductive circuit () to be inspected.

Board to board connector

An improved electrical connector has a series of terminals arranged in two parallel rows in the connector housing, with the terminals being separated into upper and lower levels. The tail portions of the upper terminals have intermediate portions that are bent down to descend obliquely from the rear side of the connector housing while the tail portions of the lower terminals have corresponding intermediate portions that are bent up to rise obliquely from the rear side of the connector housing. The intermediate portions of the upper and lower rows of terminals meet with the solder tail portions of the tail portions along a common length so that the tail portions of both upper and lower rows have the same electrical length. The intermediate portions of both rows of terminals are also tapered, or flared along their length so that they have a larger surface area where they exit the connector housing than where they join to their associated solder tail portions. This tapering also assists in maintaining a desired impedance of the connector tail.
