Multipole electrical connector

Claim 2

A multipole electrical connector comprising: a housing having a fitting cavity opening on a front side thereof; at least one insulation plate extending forwardly into said fitting cavity from a rear wall of said housing; a plurality of terminal receiving channels formed on opposite sides of said insulation plate at a predetermined pitch; at least one terminal plate receiving recess formed on a rear side of said housing and separated from said fitting cavity by said rear wall; a plurality of terminal apertures formed through said rear wall so as to communicate with said respective terminal receiving channels on said insulation plate; a terminal plate; a plurality of terminals planted on said terminal plate at a predetermined pitch to form a terminal unit; said terminal unit being fitted in said receiving recess and secured to said housing by inserting said terminals into said receiving channels through said terminal apertures.

Claim 3

A multipole electrical connector comprising: a housing having a fitting cavity opening on a front side thereof; at least one insulation plate extending forwardly into said fitting cavity from a rear wall of said housing; a plurality of power terminal receiving channels formed on one side of said insulation plate at a predetermined pitch; a plurality of signal terminal receiving channels formed on the other side of said insulation plate at a half of said predetermined pitch; at least one terminal plate receiving recess formed on a rear side of said housing; a plurality of terminal apertures formed on said receiving recess so as to communicate with said respective terminal receiving channels on said insulation plate; a terminal plate; a plurality of power terminals and signal terminals planted on said terminal plate at said predetermined pitch and a half of said predetermined pitch, respectively to form a terminal unit; and said terminal unit being fitted in said receiving recess and secured to said housing by placing said power and signal terminals into said respective receiving channels through said terminal apertures.

Claim 4

A multipole electrical connector comprising: a housing having a fitting cavity opening on a front side thereof; at least one insulation plate extending forwardly into said fitting cavity from a rear wall of said housing; a plurality of power terminal receiving channels formed on one side of said insulation plate at a predetermined pitch; a plurality of signal terminal receiving channels formed on the other side of said insulation plate at a half of said predetermined pitch; at least one terminal plate receiving recess formed on a rear side of said housing; a plurality of terminal apertures formed on said receiving recess so as to communicate with said respective terminal receiving channels on said insulation plate; a terminal plate; a plurality of power terminals and signal terminals planted on said terminal plate at said predetermined pitch and a half of said predetermined pitch, respectively to form a terminal unit; and said terminal unit being fitted in said receiving recess and secured to said housing by placing said power and signal terminals into said respective receiving channels through said terminal apertures.

Claim 5

A multipole electrical connector comprising: a housing having a fitting cavity opening on a front side thereof; at least one insulation plate extending forwardly into said fitting cavity from a rear wall of said housing; a plurality of terminal receiving channels formed on opposite sides of said insulation plate at a predetermined pitch; at least one terminal plate receiving recess formed on a rear side of said housing and separated from said fitting cavity by said rear wall; a plurality of terminal apertures formed through said rear wall so as to communicate with said respective terminal receiving channels on said insulation plate; a terminal plate; a plurality of terminals planted on said terminal plate at a predetermined pitch to form a terminal unit; said terminal unit being fitted in said receiving recess and secured to said housing by fusing said terminal plate to said receiving recess.

Claim 6

A multipole electrical connector comprising: a housing having a fitting cavity opening on a front side thereof; at least one insulation plate extending forwardly into said fitting cavity from a rear wall of said housing; a plurality of terminal receiving channels formed on opposite sides of said insulation plate at a predetermined pitch; at least one terminal plate receiving recess formed on a rear side of said housing and separated from said fitting cavity by said rear wall; a plurality of terminal apertures formed through said rear wall so as to communicate with said respective terminal receiving channels on said insulation plate; a terminal plate; a plurality of terminals planted on said terminal plate at a predetermined pitch to form a terminal unit; said terminal unit being fitted in said receiving recess and secured to said housing by fusing said terminal plate to said receiving recess.

Claim 7

The multipole electrical connector of claim 3, wherein said terminal plate is fused to said receiving recess by means of a ultrasonic welding method.

Claim 8

The multipole electrical connector of claim 4, wherein said terminals have a terminal leg extending rearwardly from said terminal plate to be soldered to a printed circuit board.
