Locking system for an electrical connector assembly
First Claim
1. A locking system for an electrical connector assembly, comprising:
- a first electrical connector including a housing having a mating face and a latching surface facing in a direction generally opposite said mating face; and
a second electrical connector including a housing having a complementary mating face for interfacing with the mating face of the first connector and a metal spring latch arm cantilevered from a rearward portion of the second connector with a radiused hook portion for latchingly engaging the latching surface of the first connector, the latch arm being located for manual deflection to move said hook portion out of engagement with the latch shoulder to allow unmating of the connectors with a minimal force, and the hook portion intersecting the latching surface along a radius to produce a lateral force for deflecting the latch arm in response to an unmating force applied directly to the connectors that is greater than said minimal force.

Abstract
A locking system is provided for an electrical connector assembly which includes first and second electrical connectors. The first connector includes a housing having a mating face and a latching surface facing in a direction generally opposite the mating face. The second connector includes a housing having a complementary mating face for interfacing with the mating face of the first connector and a metal spring latch arm cantilevered from the second connector, with a hook portion for latchingly engaging the latching surface of the first connector. The latch arm is located for manual deflection to move the hook portion out of engagement with the latching surface to allow unmating of the connectors with minimal force. The hook portion is radiused therefore deflecting the latch arm in response to an unmating force applied directly to the connectors, i.e. without manual deflection of the latch arm, that is greater than the minimal force.

7. A locking system for an electrical connector assembly, comprising:
-
a first electrical connector including a housing having a mating face and a latching surface facing in a direction generally opposite said mating face; and a second electrical connector including a housing having a complementary mating face for interfacing with the mating face of the first connector and a pair of metal spring latch arms having hook portions for latchingly engaging the latching surface of the first connector, the latch arms being cantilevered from opposite sides of the housing whereby the latch arms can be manually deflected to effect unmating of the connectors with a minimal force, the hook portions being configured generally with a radius which produce a lateral force to deflect the latch arms in response to an unmating force applied directly to the connectors that is greater than said minimal force, and the latch arms including oblique lead-in lips at distal ends of the arms for engaging portions of the housing of the first connector and biasing the latch arms to a deflected position upon mating of the connectors. - View Dependent Claims (8, 9)
