Electrical connector with position assurance and double lock

Claim 2

In combination with first and second electrical connector bodies that are movable together from a separated to a fully mated position, a cooperating primary and secondary lock means to assure that the connector bodies reach the fully mated position and to provide double locking between the connector bodies, comprising, a cantilevered primary locking arm on the first connector body extending from a base, said base further including a keeper projection extending in the opposite direction to said locking arm, a latching member on the second connector body with which said primary locking arm engages as said connector bodies are moved to the fully mated position, thereby providing a primary lock between said fully mated connector bodies, said arm remaining only partially engaged with said latching member when said connector bodies are only partially mated, and, a secondary locking arm on the second connector body extending from a pivot to a forward camming end, said secondary locking arm being being rotatable about said pivot by pushing said camming end toward said second connector body, thereby engaging said camming end and said keeper projection to move said first connector body toward said second connector body, when said connector bodies are only partially mated, and thereby assure that said primary locking arm becomes fully engaged with said latching member, whereupon said camming end snaps beneath said keeper projection to indicate that said connector bodies have reached the fully mated position, said camming end also serving to capture said primary locking arm base, whereby a double lock between said connector bodies is cooperatively provided.

Claim 3

In combination with first and second electrical connector bodies that are movable together from a separated to a fully mated position, a cooperating primary and secondary lock means to assure that the connector bodies reach the fully mated position and to provide double locking between the connector bodies, comprising, a cantilevered primary locking arm on the first connector body extending from a base to a forward end, said base further including a keeper projection extending in the opposite direction to said locking arm, a latching member on the second connector body past which said locking arm forward end slides as said connector bodies are moved to the fully mated position, thereby providing a primary lock between said fully mated connector bodies, said arm forward end resting on said latching member when said connector bodies are only partially mated, and, a secondary locking arm on the second connector body including a pair of side rails spaced apart greater than the width of said primary locking arm and extending from a pivot to a forward camming end, said secondary locking arm being rotatable about said pivot by pushing said camming end toward said second connector body, thereby engaging said camming end and keeper projection to move said first connector body toward said second connector body, when said connector bodies are only partially mated, and thereby assure that said arm forward end slides past said latching member, whereupon said camming end snaps beneath said keeper projection to indicate that said connector bodies have reached the fully mated position, said camming end also serving to capture said primary locking arm base with said primary locking arm located between said spaced side rails, whereby a low profile double lock between said connector bodies is cooperatively provided.

Claim 4

In combination with first and second electrical connector bodies that are movable together from a separated to a fully mated position, a cooperating primary and secondary lock means to assure that the connector bodies reach the fully mated position and to provide double locking between the connector bodies, comprising, a cantilevered primary locking arm on the first connector body extending from a base to a forward end, said base further including a keeper projection extending in the opposite direction to said locking arm, a latching member on the second connector body past which said locking arm forward end slides as said connector bodies are moved to the fully mated position, thereby providing a primary lock between said fully mated connector bodies, said arm forward end resting on said latching member when said connector bodies are only partially mated, and, a secondary locking arm on the second connector body including a pair of side rails spaced apart greater than the width of said primary locking arm and extending from a pivot to a forward camming end, said secondary locking arm being rotatable about said pivot by pushing said camming end toward said second connector body, thereby engaging said camming end and keeper projection to move said first connector body toward said second connector body, when said connector bodies are only partially mated, and thereby assure that said arm forward end slides past said latching member, whereupon said camming end snaps beneath said keeper projection to indicate that said connector bodies have reached the fully mated position, said camming end also serving to capture said primary locking arm base with said primary locking arm located between said spaced side rails, whereby a low profile double lock between said connector bodies is cooperatively provided.

Claim 5

In combination with first and second electrical connector bodies that are movable together from a separated to a fully mated position, a cooperating primary and secondary lock means to assure that the connector bodies reach the fully mated position and to provide double locking between the connector bodies, comprising, a cantilevered primary locking arm on the first connector body extending from a base to a forward end, said base further including a keeper projection extending in the opposite direction to said locking arm, a ramp on the second connector body over which said locking arm forward end slides as said connector bodies are moved to the fully mated position, thereby providing a primary lock between said fully mated connector bodies, said arm forward end resting on said ramp when said connector bodies are only partially mated, a pair of generally parallel guide walls on said second connector body between which said primary locking arm slides as said connector bodies are mated, and a secondary locking arm on said second connector body including a pair of side rails spaced apart slightly greater than said parallel guide walls and extending from a pivot to a forward camming end, said secondary locking arm being rotatable about said pivot by pushing said camming end toward said second connector body, thereby engaging said camming end and keeper projection to move said first connector body toward said second connector body, when said connector bodies are only partially mated, and thereby assure that said latching end slides over said ramp, whereupon said camming end snaps beneath said keeper projection to indicate that said connector bodies have reached said fully mated position, said camming end also serving to capture said primary locking arm base with said primary locking arm located between said guide walls and with said secondary locking arm side rails located outboard of said guide walls, whereby a low profile double lock between said connector bodies is cooperatively provided with said guide walls and said side rails providing protection for said primary locking arm.

Claim 6

In combination with first and second electrical connector bodies that are movable together from a separated to a fully mated position, a cooperating primary and secondary lock means to assure that the connector bodies reach the fully mated position and to provide double locking between the connector bodies, comprising, a cantilevered primary locking arm on the first connector body extending from a base to a forward end, said base further including a keeper projection extending in the opposite direction to said locking arm, a ramp on the second connector body over which said locking arm forward end slides as said connector bodies are moved to the fully mated position, thereby providing a primary lock between said fully mated connector bodies, said arm forward end resting on said ramp when said connector bodies are only partially mated, a pair of generally parallel guide walls on said second connector body between which said primary locking arm slides as said connector bodies are mated, and a secondary locking arm on said second connector body including a pair of side rails spaced apart slightly greater than said parallel guide walls and extending from a pivot to a forward camming end, said secondary locking arm being rotatable about said pivot by pushing said camming end toward said second connector body, thereby engaging said camming end and keeper projection to move said first connector body toward said second connector body, when said connector bodies are only partially mated, and thereby assure that said latching end slides over said ramp, whereupon said camming end snaps beneath said keeper projection to indicate that said connector bodies have reached said fully mated position, said camming end also serving to capture said primary locking arm base with said primary locking arm located between said guide walls and with said secondary locking arm side rails located outboard of said guide walls, whereby a low profile double lock between said connector bodies is cooperatively provided with said guide walls and said side rails providing protection for said primary locking arm.
