Locking clip
First Claim
1. In combination with an edge board connector for printed circuit boards and the like, a locking clip substituted for a pair of contacts in said connector to secure a printed circuit board therein, said clip comprising:
- a body portion,a pair of spaced cantilever arms extending integrally from one side of said body portion, said arms having a normally diverging configuration outside said connector and being biased to a substantially parallel configuration inside said connector,a tine on the free end of each said arm directed inwardly towards the other of said arms, each said tine having an inclined surface directed toward the free end of said arms and a sharp shoulder directed toward said body;
a locking shoulder projecting outwardly from each said arm intermediate the ends thereof, said shoulders engaging said connector to bias said arms to their parallel configuration and providing a fulcrum about which said arms pivot when a board is inserted therebetween, whereby said tines are biased for insertion into apertures in said printed circuit board to lock the board therein.

Abstract
A locking clip is disclosed for use in combination with a known edge board connector to lock a printed circuit board in the connector. The locking clip incudes a body portion having a pair of resilient cantilever legs extending therefrom in parallel spaced relation. Each leg includes locking tine on the free end thereof directed inwardly toward the opposite leg and an outwardly directed locking lance intermediate the body and the free ends of each leg. At least one pair of opposed, spaced-apart contacts are removed from a conventional zero or low insertion force edge board connector housing and replaced by the subject locking clip. The locking tines of the clip engage in opposite sides of an aperture in the printed circuit board aligned with at least one pad thereof to secure the board in the connector. The subject locking clip permits the connector to retain its low insertion force characteristics while preventing the board from working loose when subjected to vibration and other stresses.
