Printed circuit board retaining latch

Claim 2

A printed circuit board retaining latch for securely locking in place a printed circuit board plugged into a card edge connector, said retaining latch comprising a single flexible unitary member including a first end connector retainer which clamps onto the connector, said connector retainer being joined to a printed circuit board retainer through a flexible joining member, with said printed circuit board retainer being attached to a tab which facilitates the removal of the printed circuit board from its retainer, said retaining latch not requiring modification of either the printed circuit board or connector.

Claim 3

The retaining latch of claim 1, wherein the first end connector retainer secures the connector so snugly as to remain fixed to the connector when the printed circuit board is removed.

Claim 4

The retaining latch of claim 1, wherein the connector retainer is permanently attached to the connector.

Claim 5

The retaining latch of claim 1, wherein the first end of the connector retainer has gripping hooks which mesh into notches on the connector.

Claim 6

The retaining latch of claim 1, wherein the first end of the connector retainer is straight to fit a straight surface on the connector.

Claim 7

The retaining latch of claim 1, wherein the printed circuit board has an edge remote from the connector, and the printed circuit board retainer latches just enough of the circuit board for securely locking in place said printed circuit board into said card edge connector.

Claim 8

The retaining latch of claim 1, wherein the tab at the retainer end is able to open the retainer by a minimal amount of force.

Claim 9

The retaining latch of claim 1, wherein the retaining latch is made of metal and coated with an insulating coating.

Claim 10

The retaining latch of claim 1 fitted onto a connector and a circuit board to secure said connector and circuit board in a locked position.

Claim 11

A retaining latch for securing in place a printed circuit board received in a connector wherein the printed circuit board has an edge remote from the connector comprising a resilient unitary member having a first portion engaging the connector and a second portion engaging the edge of the printed circuit board, said first portion and said second portion elongated on an intermediate resilient portion integrally joining said first portion and said second portion, respectively, and a release tab integrally formed with said second portion of said retaining latch and extending therefrom away from the remote edge of said printed circuit board, said retaining latch not requiring modification of either the printed circuit board or connector.

Claim 12

A retaining latch for securing in place a printed circuit board received in a connector wherein the printed circuit board has an edge remote from the connector comprising a resilient unitary member having a first portion engaging the connector and a second portion engaging the edge of the printed circuit board, said first portion and said second portion elongated on an intermediate resilient portion integrally joining said first portion and said second portion, respectively, and a release tab integrally formed with said second portion of said retaining latch and extending therefrom away from the remote edge of said printed circuit board, said retaining latch not requiring modification of either the printed circuit board or connector.

Claim 13

A method of retaining a printed circuit board securely in a connector employing the retaining latch of claim 1 comprising the steps of inserting said printed circuit board into said connector, inserting said connector into said first end connector retainer, opening said retaining latch by putting force on said flexible joining member, inserting the open printed circuit board retainer onto the printed circuit board by a downward force on said printed circuit board retainer thereby securing said connector and said printed circuit board.
