Abstract
A connector includes a housing having a bore with a housing groove having a release angle between a housing groove bottom and a bore inside surface. A retainer defines a spring cavity having a circular radial canted coil spring disposed in the spring cavity. A pin having a tapered end in sliding engagement with the bore and provided with a circumferential groove for receiving the coil spring upon insertion of the pin into the bore. A circumferential groove includes a load angle for rotating the coil spring in an orientation in which the major spring axis is parallel to the release angle upon initial withdrawal of the pin from the bore.
Claims28
A connector having an insertion force that differs from a disconnection force comprising:
- a pin comprising an elongated body defining a pin longitudinal axis, a pin insertion end comprising a tapered surface relative to the pin longitudinal axis, and a pin groove disposed about said elongated body, said pin groove comprising two tapered surfaces that converge in a direction of the pin longitudinal axis;
- a housing comprising a housing bore having the pin disposed, at least in part, therein by moving the pin in a first direction relative to the housing to latch the pin to the housing;
- said housing bore comprising a lengthwise housing axis, a housing groove disposed on an inside surface of said housing bore and comprising a groove bottom surface being generally parallel to the lengthwise housing axis;
- said housing bore being structured to permit disconnection of the pin from the housing when moving the pin in a second direction relative to the housing, which is opposite the first direction;
- a canted coil spring comprising a plurality of coils each comprising a major axis, a minor axis, and a wire diameter sized to cooperate with the pin groove and the housing groove to permit latching and unlatching located in the pin groove and the housing groove with the plurality of coils contacting both tapered surfaces of the pin groove;
- wherein the tapered surface of the pin insertion end lifts the plurality of coils during insertion of the pin in the first direction into the housing bore, said movement in the first direction produces a connect force;
- and
- wherein at least one of the two tapered surfaces of the pin groove abuts and lifts the plurality of coils during disconnection of the pin from the housing by moving the pin in the second direction, said movement in the second direction produces a disconnect force.
A connector having an insertion force that differs from a disconnection force comprising:
- a pin comprising an elongated body defining a pin longitudinal axis, a pin insertion end comprising a tapered surface relative to the pin longitudinal axis, and a pin groove disposed about said elongated body, said pin groove comprising two non-parallel surfaces that converge;
- a housing comprising a housing bore having the pin disposed, at least in part, therein by moving the pin in a first direction relative to the housing to latch the pin to the housing:
- said housing bore comprising a lengthwise housing axis, a housing groove disposed on an inside surface of said housing bore and comprising a tapered surface and a sidewall extending therefrom, said tapered surface being tapered relative to the lengthwise housing axis and said sidewall being generally perpendicular to the lengthwise housing axis;
- the housing groove structured to permit disconnection of the pin from the housing when moving the pin in a second direction relative to the housing, which is opposite the first direction;
- a canted coil spring comprising a plurality of coils each comprising a major axis, a minor axis, and a wire diameter sized to cooperate with the pin groove and the housing groove to permit latching and unlatching located in both the pin groove and the housing groove with the plurality of coils contacting both tapered surfaces of the pin groove;
- wherein the tapered surface of the pin insertion end lifts the plurality of coils during insertion of the pin in the first direction into the housing bore, said movement in the first direction produces a connect force;
- and
- wherein at least one of the two tapered surfaces of the pin groove abuts and lifts the plurality of coils during disconnection of the pin from the housing by moving the pin in the second direction, said movement in the second direction produces a disconnect force.
A connector having an insertion force that differs from a disconnection force comprising:
- a pin comprising an elongated body defining a pin longitudinal axis, a pin insertion end comprising a tapered surface relative to the pin longitudinal axis, and a pin groove disposed about said elongated body, said pin groove comprising two tapered surfaces that converge;
- a housing comprising a housing bore having the pin disposed, at least in part, therein by moving the pin in a first direction relative to the housing to latch the pin to the housing;
- said housing bore comprising a lengthwise housing axis, a housing groove disposed on an inside surface of said housing bore and comprising a tapered surface, said tapered surface being tapered relative to the lengthwise housing axis;
- the housing groove structured to permit disconnection of the pin from the housing when moving the pin in a second direction relative to the housing, which is opposite the first direction;
- a canted coil spring comprising a plurality of coils each comprising a major axis, a minor axis, and a wire diameter sized to cooperate with the pin groove and the housing groove to permit latching and unlatching located in both the pin groove and the housing groove with the plurality of coils simultaneously contacting the two tapered surfaces of the pin groove and the tapered surface of the housing groove;
- wherein the tapered surface of the pin insertion end lifts the plurality of coils during insertion of the pin in the first direction into the housing bore, said movement in the first direction produces a connect force;
- and
- wherein at least one of the two tapered surfaces of the pin groove to abuts and lifts the plurality of coils during disconnection of the pin from the housing by moving the pin in the second direction, said movement in the second direction produces a disconnect force.
