Abstract

An ejector socket for DIP jumpers is provided which includes a socket member and a pair of opposed latches. Each latch is pivotably mounted between a pair of locking arms which are disposed on opposed ends of the socket member. The locking arms cooperate with the respective latches to enable the latches to be lockingly retained in a position where the latches will securely maintain the DIP jumper in the subject ejector socket. The latches can be rotated out of their locked positions, thereby urging the DIP jumper out of the subject ejector socket. The socket member preferably is formed from a unitary piece of plastic.

Claims

1. An ejector socket for a DIP jumper comprising:

a generally rectangular socket member including opposed top and bottom surfaces and socket apertures extending therebetween, opposed generally planar front and rear surfaces extending between said top and bottom surfaces, and opposed first and second ends, said socket member further including first and second pairs of spaced apart arms extending upwardly from said top surface, said first and second pairs of arms being disposed respectively adjacent the first and second ends of said socket member, one arm in each said pair of arms being adjacent the front surface of said socket member and the other arm in each said pair being adjacent the rear surface thereof, said socket member further including first and second pairs of spaced apart resilient fingers disposed intermediate the arms of said first and second pairs of arms respectively, each said resilient finger being generally parallel to and spaced from at least a portion of the arms in the respective first and second pairs of arms such that the resilient fingers in each said pair can be biasingly urged away from one another and toward one said arm in the respective first and second pairs of arms, each said resilient finger including a locking groove on the side thereof nearest the other resilient finger in its respective pair; and

first and second latches, each said latch including an elongated locking member and ejecting and retaining members extending generally perpendicularly from opposed ends of said locking member, said locking member including a pair of bosses dimensioned and located to be received in said locking grooves, said latches being pivotably mounted with respect to said first and second pairs of resilient fingers such that each said latch may be rotated between first and second positions, such that in said first position said locking member is disposed intermediate its respective pair of locking arms, and the locking bosses thereof are frictionally and lockingly engaged by said locking grooves and with the ejecting member of said latch being substantially parallel to said top surface of said socket member, and such that in said second position said ejecting member extends angularly from said top surface, whereby the arms of said ejector socket protect the DIP jumper mounted therein from inadvertent contact and whereby the resilient fingers biasingly move to engage the respective latches for lockingly holding the DIP jumper in the ejector socket.

2. An ejector socket as in claim 1 wherein each said boss and each said locking groove is generally V-shaped.

3. An ejector socket as in claim 1 wherein the retaining member on each said latch includes a retaining surface for lockingly retaining an electrical connector in said ejector socket.

4. An ejector socket as in claim 1 wherein said socket member is of unitary construction.

5. An ejector socket as in claim 1 wherein the top surface of said socket member includes at least one rail, said rail defining a surface upon which an electrical connector may be seated.

6. An ejector socket as in claim 1 wherein a portion of each said retaining member opposite its respective locking member is defined by a plurality of ribs extending generally parallel to the axis about which each said latch pivots.

7. An ejector socket as in claim 6 wherein the ribbed surface of said retaining member is convexly arcuate.
