Abstract
Abstract When two connector housings are half fitted together, a fitting detecting connector causes one of the connector housings to be pushed in a direction of separation by means of springs which are provided within a female connector housing 5, a spring holder 15 being inserted into this female connector housing 5 so that it can move in an anterior-posterior direction. This spring holder 15 houses coiled springs 16 and, when the two connector housings are being fitted together, a locking arm 11 rises over a stopping protrusion 2. As a result of this rising up the spring holder 15 is engaged, its movement in a posterior direction is regulated, and the coiled springs 16 are compressed. When the connector housings are completely fitted together the locking arm 11 again moves, releasing the engagement of the spring holder 15, and the spring holder 15 is pushed in a posterior direction by the spring force. In this way the separating force does not act when the connector housings are fully engaged.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
158 words
A connector housing of a male/female connector pair, the housing including a locking arm bendable from a rest condition to a bent condition on initial engagement with a locking member of a mating connector, and reverting to the rest condition on complete engagement of said locking arm and locking member, the housing further including a compression spring having one end engageable with a mating connector to urge said housing out of engagement therewith during partial fitting thereof, and a spring holder engaging the other end of said spring, the locking arm being engageable with the spring holder in the bent condition so that the spring holder moves with the locking arm in the fitting direction to compress the spring. and the spring holder being movable with respect to the housing from an advanced position to a retreated position on complete engagement of said locking arm and locking member thereby permitting compressive stress in said spring to be reduced.
Claim 2
Dependent Claim
158 words
A connector housing of a male/female connector pair, the housing including a locking arm bendable from a rest condition to a bent condition on initial engagement with a locking member of a mating connector, and reverting to the rest condition on complete engagement of said locking arm and locking member, the housing further including a compression spring having one end engageable with a mating connector to urge said housing out of engagement therewith during partial fitting thereof, and a spring holder engaging the other end of said spring, the locking arm being engageable with the spring holder in the bent condition so that the spring holder moves with the locking arm in the fitting direction to compress the spring. and the spring holder being movable with respect to the housing from an advanced position to a retreated position on complete engagement of said locking arm and locking member thereby permitting compressive stress in said spring to be reduced.
Claim 3
Dependent Claim
42 words
A housing according to claim 1 wherein said spring holder further includes latching means engageable with said housing to maintain said spring holder in the advanced position, said latching means being released on complete engagement of said locking arm and locking member.
Claim 4
Dependent Claim
34 words
A housing according to claim 1 wherein said spring is a coil spring, said one end of said spring having a seat engaged therewith, and said seat being adapted to contact a mating connector.
Claim 5
Dependent Claim
47 words
A housing according to claim 1 herein said spring holder and housing are guided with respect to each other by opposite ribs of one of the spring holder and housing, and opposite channels of the other of the spring holder and housing, said channels and ribs interengaging.
Claim 6
Dependent Claim
20 words
A housing according to claim 4 wherein said channels are narrowed at the end thereof corresponding to the retreated position.
Claim 7
Dependent Claim
22 words
A housing according to claim 1 and having a plurality of compression springs, an individual spring seat being provided for each spring.
Claim 8
Dependent Claim
39 words
A housing according to claim 6 wherein said seat comprises a shank to fit from one end of the spring within the coils thereof, the shank having a plurality of outwardly extending deformable ribs engageable tightly with said coils.
Claim 9
Dependent Claim
40 words
A housing according to claim 1 wherein said spring holder overlies said locking arm and has a bendable member adapted to contact an abutment of said locking arm, to bend said locking arm from the rest to the bent condition.
Claim 10
Dependent Claim
42 words
A housing according to claim 8 wherein said bendable member includes a pushing face for receiving a bend inducing force, the plane of said face intersecting the direction of movement of said spring holder and the direction of movement of said abutment.
Claim 11
Dependent Claim
30 words
A housing according to claim 9 wherein said bendable member includes a recess within which is located said pushing face said recess being adapted to guide an elongate release tool.
Claim 12
Dependent Claim
37 words
A housing according to claim 1 wherein said spring holder includes a bending regulating member adapted to prevent bending of said locking arm from the rest condition on complete engagement of said locking arm and locking member.
Claim 13
Dependent Claim
40 words
A housing according to claim 11 wherein said spring holder overlies said locking arm and has a bendable member adapted to contact an abutment of said locking arm, to bend said locking arm from the rest to the bent condition.
Claim 14
Dependent Claim
42 words
A housing according to claim 12 wherein said bendable member includes a pushing face for receiving a bend inducing force, the plane of said face intersecting the direction of movement of said spring holder and the direction of movement of said abutment.
Claim 15
Dependent Claim
30 words
A housing according to claim 13 wherein said bendable member includes a recess within which is located said pushing face said recess being adapted to guide an elongate release tool.
