Abstract
Abstract The present invention allows easy inspection of the conditions of soldering of a plurality of first and second contacts in a card edge connector assembly in which daughter boards are stacked in a plurality of tiers. Each of the first contacts ( 12 ) has a main body ( 12 a ), bent contact parts ( 12 c ) which extend into the accommodating recesses ( 2 and 4 ) via contact part passage grooves ( 39 and 41 ), and a tine ( 12 d ) on the lower end of the main body ( 12 a ). The plurality of second contacts ( 13 ) are constructed from contact members ( 14 and 15 ), and a conductive member ( 17 ) which electrically connect the contact members ( 14 and 15 ) on the rear part of the housing ( 6 ). Tines ( 15 g ) are formed on the lower ends of the contact members ( 15 ). The first contacts ( 12 ) are attached from the rear part of the housing ( 6 ), and the contact members ( 14 and 15 ) of the second contacts ( 13 ) are attached from the front part of the housing ( 6 ).

Claim 1
Independent Claim
264 words
A card edge connector assembly comprising: an insulating housing attached to a mother board; the insulating housing having a front part and a rear part and a first daughter board accommodating recess and a second daughter board accommodating recess formed in a plurality of tiers in the front part of the insulating housing; the first and the second daughter board accommodating recesses having an upper side and a lower side; a plurality of first contacts having integral first and second contact parts mounted from the rear part of the housing such that the first contact part is received in the upper side of the first daughter board accommodating recess and the second contact part is received in the upper side of the second daughter board accommodating recess; the first contacts having a first tine that extends from the rear part of the housing and is mounted to the mother board; a plurality of second contacts having first and second contact members mounted from the front part of the housing such that the first contact member is received in the lower side of the first daughter board accommodating recess and the second contact member is received in the lower side of the second daughter board accommodating recess; the second contact member having a second tine that extends from the front part of the housing and is mounted to the mother board; and a conductive member mounted in the rear part of the housing opposite the first and the second daughter board accommodating recesses that electrically connects the first contact member to the second contact member.
Claim 2
Dependent Claim
264 words
A card edge connector assembly comprising: an insulating housing attached to a mother board; the insulating housing having a front part and a rear part and a first daughter board accommodating recess and a second daughter board accommodating recess formed in a plurality of tiers in the front part of the insulating housing; the first and the second daughter board accommodating recesses having an upper side and a lower side; a plurality of first contacts having integral first and second contact parts mounted from the rear part of the housing such that the first contact part is received in the upper side of the first daughter board accommodating recess and the second contact part is received in the upper side of the second daughter board accommodating recess; the first contacts having a first tine that extends from the rear part of the housing and is mounted to the mother board; a plurality of second contacts having first and second contact members mounted from the front part of the housing such that the first contact member is received in the lower side of the first daughter board accommodating recess and the second contact member is received in the lower side of the second daughter board accommodating recess; the second contact member having a second tine that extends from the front part of the housing and is mounted to the mother board; and a conductive member mounted in the rear part of the housing opposite the first and the second daughter board accommodating recesses that electrically connects the first contact member to the second contact member.
Claim 3
Dependent Claim
34 words
The card edge connector assembly of claim 1 , wherein the first contacts have first main bodies integral with the first and second contact parts from which the first and second contact parts extend.
Claim 4
Dependent Claim
28 words
The card edge connector assembly of claim 2 , wherein the first main bodies have a first attachment tab press fit into a first through-hole of the housing.
Claim 5
Dependent Claim
35 words
The card edge connector assembly of claim 1 , wherein the first tine extends from the rear part of the housing to allow visual inspection when the first tine is soldered to the mother board.
Claim 6
Dependent Claim
35 words
The card edge connector assembly of claim 1 , wherein the second tine extends from the front part of the housing to allow visual inspection when the second tine is soldered to the mother board.
Claim 7
Dependent Claim
45 words
The card edge connector assembly of claim 1 , wherein the first tines and the second tines have a pitch substantially the same as the first contacts and the second contacts to prevent solder bridges from forming between the first tines and the second tines.
Claim 8
Dependent Claim
53 words
The card edge connector assembly of claim 1 , wherein the conductive member has a conductive member attachment tab press fit into a second through hole of the housing and a first contact leg that extends toward the first contact member and a second contact leg that extends toward the second contact member.
Claim 9
Dependent Claim
27 words
The card edge connector assembly of claim 7 , wherein the conductive member and the first contact leg and the second contact leg form a substantially c-shape.
Claim 10
Dependent Claim
57 words
The card edge connector assembly of claim 7 , wherein the first contact member has a first contact member attachment tab that contacts the first contact leg and the second contact member has a second contact member attachment tab that contacts the second contact leg to electrically connect the first contact member to the second contact member.
Claim 11
Dependent Claim
51 words
The card edge connector assembly of claim 1 , wherein the insulating housing has first upper and lower contact through-holes in the rear part of the housing for receiving the first contacts and second upper and lower contact through-holes in the front part of the housing for receiving the second contacts.
