Abstract
Abstract A latching device (10) for a card edge connector (30) and auxiliary board (60) having a first arm (12) and a second arm (14), wherein the second arm includes a latching unit (20) and a latching release unit (26), when the latching device (10) is inserted into a receptacle compartment (46) in the connector (30), the first arm (12) is biased toward the second arm for fixing the latching device (10) in the receptacle compartment. The latching unit (20) includes round shoulders (22, 24) which are provided to fit into round recesses (62) of an auxiliary board (60). A directed pressure (A, B, C) placed on the release unit (26) causes the latching unit (20) to rotate away from an area in card edge connector (30) where an auxiliary board is disposed.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
88 words
A card edge connector having a latching device and an auxiliary board, said latching device having a first arm and a second arm, wherein the second arm includes a latching unit and a latching release unit, characterized in that: when the latching device is inserted into a receptacle compartment in the connector, the first arm is biased (resiles) toward the second arm for fixing the latching device in the receptacle compartment, and wherein the latching unit includes arcuate shoulders to fit into arcuate recesses of the auxiliary board.
Claim 2
Dependent Claim
88 words
A card edge connector having a latching device and an auxiliary board, said latching device having a first arm and a second arm, wherein the second arm includes a latching unit and a latching release unit, characterized in that: when the latching device is inserted into a receptacle compartment in the connector, the first arm is biased (resiles) toward the second arm for fixing the latching device in the receptacle compartment, and wherein the latching unit includes arcuate shoulders to fit into arcuate recesses of the auxiliary board.
Claim 3
Dependent Claim
23 words
The card edge connector of claim 1, wherein the radius of curvature of the shoulders is smaller than that of the round recesses.
Claim 4
Dependent Claim
32 words
The latching device of claim 1, wherein during insertion of the latching device into the receptacle compartment the first and second arms are moved from a nonparallel to a substantially parallel relationship.
Claim 5
Dependent Claim
21 words
The latching device of claim 3, wherein the latching device is in a spring-loaded state when inserted into the receptacle compartment.
Claim 6
Dependent Claim
37 words
The latching device of claim 1, wherein a directed pressure placed on the release unit causes the latching unit to rotate away from an area in the card edge connector where an auxiliary board would be disposed.
Claim 7
Dependent Claim
38 words
The card edge connector of claim 5, wherein the second arm is subjected to a torsionally directed stress when a directed pressure is applied to the release unit with a portion of the housing acting as a fulcrum.
Claim 8
Dependent Claim
142 words
A card edge connector having a latching device and an auxiliary board, said latching device having a first arm and a second arm joined by a bent section so that the first arm and the second arm are nonparalled to one another prior to being mounted to a mounting section of the electrical connector, the first arm and the second arm being substantially parallel when mounted in the mounting section of the electrical connector; a latching section on one of the first arm or the second arm for latching the auxiliary board in the electrical connector; and a latch release section provided on the second arm which when a release force is applied thereto causes the second arm to torsionally move thereby moving the latching section free of the auxiliary board enabling the auxiliary board to be removed from the electrical connector.
Claim 9
Dependent Claim
142 words
A card edge connector having a latching device and an auxiliary board, said latching device having a first arm and a second arm joined by a bent section so that the first arm and the second arm are nonparalled to one another prior to being mounted to a mounting section of the electrical connector, the first arm and the second arm being substantially parallel when mounted in the mounting section of the electrical connector; a latching section on one of the first arm or the second arm for latching the auxiliary board in the electrical connector; and a latch release section provided on the second arm which when a release force is applied thereto causes the second arm to torsionally move thereby moving the latching section free of the auxiliary board enabling the auxiliary board to be removed from the electrical connector.
Claim 10
Dependent Claim
50 words
The card edge connector as claimed in claim 7, wherein the latching section has a tapered surface for engagement by the auxiliary board to move the arm on which the latching section is located toward the other arm so that the auxiliary board can be moved to a latching position.
Claim 11
Dependent Claim
26 words
A latching device as claimed in claim 7, wherein the latching section includes generally arcuate shoulders to fit into an arcuate recess in the auxiliary board.
Claim 12
Dependent Claim
28 words
The card edge connector as claimed in claim 7, wherein a fixing arm is provided on the first arm for fixing the electrical connector onto a mother board.
Claim 13
Dependent Claim
150 words
An electrical connector for mounting on a mother board and for receiving an auxiliary board therein, comprising: a housing having electrical contacts secured therein, contact sections of the electrical contacts extending into a board-receiving opening in the housing for electrical connection with conductive pads of the auxiliary board being positioned in the board-receiving opening; a latching device mounted on the housing and having a first arm and a second arm engaging respective sections of the housing whereby the first arm is biased toward the second arm; a latching section on the second arm for engagement with the auxiliary board for latching the auxiliary board to the housing; and a latch release section on the second arm which causes the second arm to rotate upon a force being applied thereto thereby moving the latching section free of the auxiliary board to enabling the auxiliary board to be removed from the connector.
Claim 14
Dependent Claim
150 words
An electrical connector for mounting on a mother board and for receiving an auxiliary board therein, comprising: a housing having electrical contacts secured therein, contact sections of the electrical contacts extending into a board-receiving opening in the housing for electrical connection with conductive pads of the auxiliary board being positioned in the board-receiving opening; a latching device mounted on the housing and having a first arm and a second arm engaging respective sections of the housing whereby the first arm is biased toward the second arm; a latching section on the second arm for engagement with the auxiliary board for latching the auxiliary board to the housing; and a latch release section on the second arm which causes the second arm to rotate upon a force being applied thereto thereby moving the latching section free of the auxiliary board to enabling the auxiliary board to be removed from the connector.
Claim 15
Dependent Claim
26 words
An electrical connector as claimed in claim 11, wherein said latching section includes generally arcuate shoulders to fit into an arcuate recess in the auxiliary board.
Claim 16
Dependent Claim
22 words
An electrical connector as claimed in claim 11, wherein the latching section and the latch release section are offset from on another.
Claim 17
Dependent Claim
