Printed circuit board connector
First Claim
1. A printed circuit board connector comprising:
- an insulating housing having a bottom junction surface and a top surface;
a plurality of pin holes formed at a given pitch and through the insulating housing so as to extend from the junction surface to the top surface;
plating layers each covering an inner periphery of a pin hole in a region of the junction surface, with the region continuing to the inner periphery, so that a portion of the plating layer coating the region provides a lead capable of being soldered to a conductive pattern formed on a printed circuit board;
ears each integral with and protruding sideways from a side surface of the insulating housing, each ear being located to correspond to a pin hole and coated with the plating layer;
guide grooves each formed in a bottom of the lead to extend from an outer extremity of the ear to the pin hole, so that when said connector is soldered to a circuit board, the guide grooves guide a molten solder along the grooves towards the pin hole; and
pin contacts, each having at a basal end a flange and inserted into the pin hole from the junction surface of the insulating housing so as to jut upward from the top surface, such that each pin contact is firmly held in the pin hole,wherein the flanges are kept in electrical contact with the respective leads to thereby form a pin header of the surface-mountable type;
said printed circuit board connector further comprising a socket connector engageable with the pin header, the socket connector comprising;
a plurality of socket contacts embedded in another insulating housing, the socket contacts being spaced apart from one another and arranged to correspond to the pin contacts;
each socket contact having a connectable portion and a lead extending therefrom, the connectable portion being a flat and bifurcated conductive piece extending perpendicular to an axis of a pin contact; and
minute apertures formed through the other insulating housing such that the pin contacts are insertable in the socket connector front to back, or vice versa.

Abstract
A printed circuit board connector has: an insulating housing (2); SMT type contacts (7, 11) disposed in the insulating housing and spaced apart from each other; and each contact having a lead (11) which extends to a junction surface (2a) of the housing so as to be soldered to a conductive pattern (16) formed on a printed circuit board (15). The lead (11) of each contact is a plating layer (10) formed on the junction surface (2a). The contacts (7) are pin contacts held in place by the insulating housing (2) so as to be electrically connected to the plating layer (10) formed as the leads. The contacts'"'"' leads are included in a common plane so that the reliability of electric connection and the durability of connector are improved, and the connector is rendered thinner and more compact to reduce an area required to mount it.
