Abstract
Abstract A connector is provided with a retainer 30 which can be held displaceably from a partial lock position to a full lock position with respect to a housing 10. An inadvertent movement of the retainer 30 from the partial lock position to the full lock position is prevented by providing a locking control member 34. Accordingly, the retainer 30 does not make an inadvertent movement even if it is struck against something, e.g. during transportation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
243 words
A connector comprising: a housing (10) and a retainer (30), the housing (10) being provided with terminal fitting chambers (11) for accommodating terminal fittings (20) and with a retainer insertion opening (15) into which the retainer (30) is insertable for retention therein, the retainer (30) having engaging means engageable with the housing (10) for selectively holding the retainer (30) in a partial lock position and a full lock position with respect to the housing (10), said retainer (30) being configured for detachment of the terminal fittings (20) when retainer (30) is in its partial lock position and for securely retaining the terminal fittings (20) in the housing (10) when the retainer (30) is in its full lock position, and wherein said retainer (30) further comprising a locking control member (34) for preventing movement of the retainer (30) from the partial lock position to the full lock position, said locking control member (34) including a manual actuator for selectively releasing the locking control member (34) to enable movement of the retainer (30) to the full lock position, the locking control member (34) being provided at a rear end of the retainer (30) with respect to an insertion direction of the retainer (30) and being provided with a flexible portion in the form of a cantilevered arm projecting rearwardly with respect to the insertion direction for deflection in a direction substantially normal to the insertion direction to permit a push-in operation of the retainer (30).
Claim 2
Dependent Claim
243 words
A connector comprising: a housing (10) and a retainer (30), the housing (10) being provided with terminal fitting chambers (11) for accommodating terminal fittings (20) and with a retainer insertion opening (15) into which the retainer (30) is insertable for retention therein, the retainer (30) having engaging means engageable with the housing (10) for selectively holding the retainer (30) in a partial lock position and a full lock position with respect to the housing (10), said retainer (30) being configured for detachment of the terminal fittings (20) when retainer (30) is in its partial lock position and for securely retaining the terminal fittings (20) in the housing (10) when the retainer (30) is in its full lock position, and wherein said retainer (30) further comprising a locking control member (34) for preventing movement of the retainer (30) from the partial lock position to the full lock position, said locking control member (34) including a manual actuator for selectively releasing the locking control member (34) to enable movement of the retainer (30) to the full lock position, the locking control member (34) being provided at a rear end of the retainer (30) with respect to an insertion direction of the retainer (30) and being provided with a flexible portion in the form of a cantilevered arm projecting rearwardly with respect to the insertion direction for deflection in a direction substantially normal to the insertion direction to permit a push-in operation of the retainer (30).
Claim 3
Dependent Claim
64 words
A connector according to claim 1, wherein a contact projection (34a, 34b) is formed at the flexible portion of said locking control member (34) and is dimensioned to come into contact with a part of an opening edge (15c, 16) of the retainer insertion opening (15) making any further insertion of the retainer (30) impossible prior to deflection of the locking control member (34).
Claim 4
Dependent Claim
44 words
A connector according to claim 1, wherein said insertion opening (15) of said housing (10) is formed such that the retainer (30) and said locking control member (34) can be accommodated substantially entirely, without protruding from said housing (10), in the full lock position.
Claim 5
Dependent Claim
56 words
A connector according to claim 3, wherein said housing (10) comprises a recess (15c1; 15c2) for accommodating said contact projection (34a, 34b) in the full lock position, and during movement from one position to the other, said recess (15c1; 15c2) being an opening (15c2) for operatively disengaging said contact projection (34a, 34b) from said housing (10).
Claim 6
Dependent Claim
63 words
A connector according to claim 1, wherein the retainer (30) comprises at least one engaging portion (32, 33) on each of opposite side of said retainer (30) and extending substantially perpendicular to the direction of insertion of said retainer (30) into said housing (10) said engaging portions (32, 34) being engageable with the housing (10) in at least one of the lock positions.
Claim 7
Dependent Claim
24 words
A connector according to claim 5, wherein the retainer (30) is formed with a recess for facilitating deformation of said engaging portion (32, 33).
Claim 8
Dependent Claim
35 words
A connector according to claim 5, wherein walls of said housing (10) defining said opening (15) are provided with at least one projection (15a, 15b) for cooperating with and engaging said engaging portion (32, 33).
Claim 9
Dependent Claim
43 words
A connector according to claim 7, comprising at least two said projections (15a, 15b) disposed respectively on opposite sides of said opening (15) and being offset in the direction of insertion of said retainer (30) into said opening (15) in said housing (10).
Claim 10
Dependent Claim
28 words
A connector according to claim 8, wherein said housing (10) comprises at least one opening for operatively disengaging said engaging portion (32, 33) from said projection (15a, 15b).
Claim 11
Dependent Claim
60 words
A connector according to claim 9, wherein said engaging portion (32, 33), said projection (15a, 15b), said opening for operatively disengaging said engaging portion (32, 33) from said projection (15a, 15b), said contact projection (34a, 34b) and said opening for operatively disengaging said contact projection (34a, 34b) from said housing (10) extend substantially normal to the direction of insertion, and
