Abstract
The present invention relates to electrical connectors and, more particularly, to cam levers for injecting and ejecting a connector from another part.
Claims17
An inject and eject cam lever assembly for providing a mechanical advantage while forcing a first connector into a mated position with a second connector, the assembly comprising:
- a first protrusion for extending from a first side of either the first connector or the second connector;
- and
- a first lever for pivotably mounting about a pivot on a first side of the connector without the protrusion, the lever having a grip and a groove or slot for receiving the protrusion, the groove or slot having a mouth end, an inject cam surface and an eject cam surface, the cam surfaces having varying cam angles to control the mechanical advantage of the lever along its stroke,
- such that the connectors can be injected to and ejected from the mated position by positioning the first connector adjacent the second connector substantially before the force is applied, positioning the lever with the protrusion in the mouth end, applying a force on the grip in a first direction camming the protrusion against the inject cam surface until the connectors are in the mated position, and applying a force on the grip in a second direction camming the protrusion against the eject cam surface until the protrusion is substantially in the first position.
1 more element
An electrical connector assembly comprising:
- a first connector having a housing and a plurality of electrical contact elements;
- a second connector having a housing and a plurality of electrical contact elements, the second connector adapted to mate with the first connector when a force is exerted to push or pull the connectors together;
- a first protrusion extending from a first side of the housing of either the first connector or the second connector;
- and
- a first lever pivotably mounted about a pivot on a first side of the housing of the connector without the protrusion, the lever having a grip and a groove or slot for receiving the protrusion, the groove or slot having a mouth end, an inject cam surface and an eject cam surface, the cam surfaces having varying cam angles to control the mechanical advantage of the lever along its stroke,
- such that the connectors can be injected to and ejected from a mated position by positioning the first connector adjacent the second connector substantially before the force is applied, positioning the lever with the protrusion in a first position in the mouth end, applying a force on the grip in a first direction camming the protrusion against the inject cam surface until the connectors are in the mated position, and applying a force on the grip in a second direction camming the protrusion against the eject cam surface until the protrusion is substantially in the first position.
