Abstract
Abstract A two part connector has latch arms (4) and ramps (3) which latch together to give positive mating in known manner. To facilitate release the arms (4) are depressible in the mated condition to allow withdrawal of latch projections (6) below ramps (3). Resilient stop fingers (15) may be provided to inhibit mismating.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
261 words
An electrical connector assembly comprising two housing parts each containing one or more terminals, the housing parts and terminals being such that the housing parts can be mated thereby to mate the terminals contained therein, the housing parts having interengaging latching members which provide a force which assists in mating of the two housing parts, and which serve to secure the housing parts together in their mated condition, the latching members comprising on one housing part a ramp or ramps on each of two opposite sides of the housing part, and on the other housing part a resilient cantilever arm on each of two opposite sides of said other housing part, each arm carrying a projection adapted and arranged to ride over a ramp on the one housing part as the two housing parts are mated, the ramps on the one housing part and the projections on the arms of the other housing part having cooperating surfaces which engage when the housing parts are fully mated, to prevent unmating of the housing parts, in which the ramps are supported on the one housing part such that deflection of the arms of the other housing part towards the one housing part when the housing parts are mated disengages the cooperating surfaces of the ramps and projections and enables the housing parts to be unmated without further deformation of the arms, with the projections on the arms of the other housing part passing under the ramps on the one housing part, whereby the projections offer no resistance to unmating of the housing parts.
Claim 2
Dependent Claim
261 words

Claim 3
Dependent Claim
79 words
An assembly as claimed in claim 1, in which said one housing part has a single said ramp on each of said opposite sides, each said ramp being supported by a limb of less width than said ramp, and each arm on the other housing part is split longitudinally into two members, there being a projection on the inner surface of each member, which projections pass along opposite sides of the respective limb when the housing parts are unmated.
Claim 4
Dependent Claim
88 words
An assembly as claimed in claim 1, in which each arm of the other housing part carries a projection on each of its outwardly facing side surfaces, there being two ramps on each side of the one housing part respectively associated with the two projections on the associated arm, the two ramps being separated laterally of the one housing part, the projections on each arm passing under the associated ramps and between the limbs supporting the two ramps associated with the arm when the housing parts are unmated.
Claim 5
Dependent Claim
56 words
An assembly as claimed in claim 1, in which resilient stop members are provided on the one housing parts arranged and adapted to inhibit mating of the housing parts when the arms of the other housing part are deflected towards the one housing part but which by flexure permit unmating with the arms in that position.
Claim 6
Dependent Claim
71 words
An assembly as claimed in claim 2, in which each arm is provided with a stop member in the form of a resilient finger directed obliquely inwards and in the mating direction, the stop members being arranged to inhibit mating of the housing parts when the arms of the other housing part are deflected towards the one housing part but which by flexure permit unmating with the arms in that position.
Claim 7
Dependent Claim
21 words
An assembly as claimed in claim 5, in which the fingers are positioned forwardly of the projections in the mating direction.
Claim 8
Dependent Claim
75 words
An assembly as claimed in claim 3, in which the one housing part is provided with stop members in the form of resilient fingers positioned beneath the ramps and directed obliquely outwardly and in the mating direction, the fingers being arranged to inhibit mating of the housing parts when the arms of the other housing part are deflected towards the one housing part but which by flexure permit unmating with the arms in that position.
