Abstract:
1. A matrix board-to-board connector assembly for interconnecting a pair of circuit boards in parallel spaced-apart planes, the assembly comprising: a receptacle connector including a first housing with a plurality of first contacts received therein, the first housing having a first base planar board, the first base planar board having a matrix array of first opening recesses configured therein, each first opening recess extending transversely, said first contacts being secured in a respective one of said first opening recesses, each of said first contacts having a middle-connecting portion, two touching pins and at least one first soldering legs said two touching pins extending from one end of said middle-connecting portion, said first soldering leg extending from an opposite end of said middle-connecting portion; and a plug connector including a second housing with a plurality of second contacts received therein, the second housing having a matrix array of second opening recesses configured therein, each of said second opening recesses having a transverse recess and a longitudinal recess crossing the transverse recess, each of said second contacts being retained in a corresponding longitudinal recess, each of said second contacts having a touching portion, two guiding pins and at least one second soldering leg, said two guiding pins extending from one end of said touching portion, said second soldering leg extending from an opposite end of said touching portion, wherein a distal end of each of said guiding pins extends no further than flush with said corresponding second opening recesses; wherein when the receptacle connector and the plug connector are mated, said touching pins on each of said first contacts are orthogonally received between the two guiding pins of a corresponding one of said second contacts so that said guiding pins of said second contacts are located on opposing sides of said middle-connecting portion of said first contacts and said touching pins of said first contacts engage opposing sides of said touching portion of said second contacts in mechanical contact therewith said two touching pins being inserted into the transverse recess of the corresponding one of said second opening recesses.
