Abstract

A mechanically assisted electrical connector including a lever and a slider. The slider is coupled to the lever such that movement of the lever moves the slider. The slider defines a slot that is configured to cooperate with a post of a mating connector in a manner effective to urge the electrical connector and the mating connector together when the lever is moved from a first position to a second position. A ramp angle of the slot is varied to reduce a peak value of an applied force to advance the lever from the first position to the second position when connecting the electrical connector to the mating connector.

Claims

1. A electrical connector comprising:

a lever moveably coupled to the electrical connector and moveable from a first position to a second position; and

a slider slideably coupled to the electrical connector and coupled to the lever such that rotational movement of the lever from the first position to the second position moves the slider laterally, wherein the slider defines a slot having a ramp having a non-constant radius between a slot opening portion and a slot end portion, said ramp configured to engage a post of a mating connector in a manner effective to urge the electrical connector and the mating connector together when the lever is moved from the first position to the second position, wherein the ramp is curved such that a slope of the ramp is not constant along a length of the ramp and wherein the slope of the ramp is configured to reduce a peak value of an applied force to advance the lever from the first position to the second position when connecting the electrical connector to the mating connector.

2. The electrical connector of claim 1, wherein said slope of the ramp is varied in accordance with the mathematical formula dy/dx=nx^n-1.

3. The electrical connector of claim 1, wherein said slope of the ramp is varied in accordance with an engagement force generated by the electrical connector and the mating connector when the electrical connector and the mating connector are urged together.

4. The electrical connector of claim 3, wherein said slope of the ramp is further varied in accordance with a mechanical advantage of the lever to move the slider.
