Abstract
Abstract An electrical connector assembly has a socket body which is mounted on a printed board and is adapted for receiving a complementary plug with contacts. The socket body has a bottom and a pair of opposed side walls defining therebetween a cavity for receiving the plug. The socket body carries a plurality of connector contacts, each of which is bent to define an inner leg and an outer leg both extending from a bent. The inner leg extends along an inner surface of the side wall within the cavity for engagement with the contacts of the plug, while the outer leg extends downwardly from the bent along an outer surface of the side wall to define a terminal lead at its lower end. The terminal lead projects generally horizontally outwardly from the bottom of the socket body so as to be registered on a corresponding terminal site of a conductor pattern on the printed board and is welded thereto. With this structure, the entire terminal leads can be viewed for facilitating a visual inspection of possible soldering failure at the terminal leads.

Claim 1
Independent Claim
316 words
An electrical connector assembly which comprises: a socket body mounted on a printed board, said socket body having a bottom and a pair of opposed side walls defining therebetween a cavity for detachably receiving a complementary plug with a plurality of contacts; said socket body comprising a stationary base and a movable base movable relative to said stationary base and formed with said bottom and a pair of said side walls defining therebetween said cavity, a plurality of connector contacts carried by said socket body, each of said connector contacts being bent to define an inner leg and an outer leg both extending from a bent, said inner leg extending along an inner surface of said side wall within said cavity for electrical connection with the contacts of said plug, said outer leg extending downwardly from said bent along an outer surface of said side wall to define a terminal lead at its lower end, said terminal lead projecting generally horizontally outwardly from the bottom of said socket body so as to be registered on a corresponding terminal site of a conductor pattern on said printed board and welded thereto; said connector contacts including a clamping leg extending from said bent between said inner and outer legs in a spaced relation thereto, said clamping leg extending in engagement with the outer surface of said side wall so as to clamp said side wall between said clamping leg and said inner leg, said outer leg extending downwardly from said bent in a spaced relation outwardly of said clamping leg so as to be given a resiliency which allows said clamping and inner legs to move together with said movable base relative to said stationary base in a direction of varying a spacing between the outer leg and said clamping leg, said outer leg having said terminal lead extending outwardly from a lower end of said stationary base.
Claim 2
Dependent Claim
316 words
An electrical connector assembly which comprises: a socket body mounted on a printed board, said socket body having a bottom and a pair of opposed side walls defining therebetween a cavity for detachably receiving a complementary plug with a plurality of contacts; said socket body comprising a stationary base and a movable base movable relative to said stationary base and formed with said bottom and a pair of said side walls defining therebetween said cavity, a plurality of connector contacts carried by said socket body, each of said connector contacts being bent to define an inner leg and an outer leg both extending from a bent, said inner leg extending along an inner surface of said side wall within said cavity for electrical connection with the contacts of said plug, said outer leg extending downwardly from said bent along an outer surface of said side wall to define a terminal lead at its lower end, said terminal lead projecting generally horizontally outwardly from the bottom of said socket body so as to be registered on a corresponding terminal site of a conductor pattern on said printed board and welded thereto; said connector contacts including a clamping leg extending from said bent between said inner and outer legs in a spaced relation thereto, said clamping leg extending in engagement with the outer surface of said side wall so as to clamp said side wall between said clamping leg and said inner leg, said outer leg extending downwardly from said bent in a spaced relation outwardly of said clamping leg so as to be given a resiliency which allows said clamping and inner legs to move together with said movable base relative to said stationary base in a direction of varying a spacing between the outer leg and said clamping leg, said outer leg having said terminal lead extending outwardly from a lower end of said stationary base.
Claim 3
Dependent Claim
65 words
An electrical connector assembly as set forth in claim 1, wherein said socket body includes a pair of stands on opposite ends of said socket body, said stands extending downwardly past said bottom to rest upon said printed board at the respective lower ends of said stands so as to define an open space between said bottom of the socket body and said printed board.
Claim 4
Dependent Claim
45 words
An electrical connector assembly as set forth in claim 1, wherein the lower end of said outer leg is bifurcated to form said terminal lead and an anchor segment which is positioned immediately inwardly of said terminal lead and is anchored in said stationary base.
Claim 5
Dependent Claim
67 words
An electrical connector assembly as set forth in claim 3, wherein each of said side walls of said movable base is formed with a groove extending from the inner surface to the outer surface thereof for receiving said inner and clamping legs, said inner leg having its lower end fitted into a corresponding slot in the bottom of said movable base so as to be anchored thereto.
Claim 6
Dependent Claim
45 words
An electrical connector assembly as set forth in claim 4, said connector contact is positioned in said groove so as to leave a clearance between the bent of said connector contact and a bottom of said groove at an upper end of said side wall.
Claim 7
Dependent Claim
211 words
An electrical connector assembly which comprises: a socket body mounted on a printed board, said socket body having a bottom and a pair of opposed side walls defining therebetween a cavity for detachably receiving a complementary plug with a plurality of contacts; a plurality of connector contacts carried by said socket body, each of said connector contacts being bent to define an inner leg and an outer leg both extending from a bent, said inner leg extending along an inner surface of said side wall within said cavity for electrical connection with the contacts of said plug, said outer leg extending downwardly from said bent along an outer surface of said side wall to define a terminal lead at its lower end, said terminal lead projecting generally horizontally outwardly from the bottom of said socket body so as to be registered on a corresponding terminal site of a conductor pattern on said printed board and welded thereto; each of said side walls of said socket body being formed with a groove extending from the inner surface to the outer surface thereof for receiving said connector contact, said inner leg having its lower end fitted into a corresponding slot in the bottom of said socket body so as to be anchored thereto.
Claim 8
Dependent Claim
