Abstract
Abstract To offer a locking connector having a double-lock device with a positioner determining the position of the contacts. Cavities 8 are formed in the housing 2. A double-lock device 50 having cavities 64 corresponding to the cavities 8 is inserted in a recess 14 in the housing 2. At the pressure section 54 of the double-lock device 50, an extension 56 is made. From the front end of the extension 56, a connector positioner 58 extends vertically downward along the joining surface 4. The positioner 58 has an opening 60 and front edge 62 which determine position of the contacting sections 102 of the contacts 100 when the double-lock device 50 is in the fully locked position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A locking electrical connector comprising a housing, at least one contact, each contact having a front end matable with other contacts at a joining surface on said connector, and a locking device whose main body is inserted through a side wall of said housing in a direction substantially normal to the side wall, the locking device being engaged with each contact retained in said housing, characterized by the fact that: said main body of said locking device has an extension emerging from the surface of a pressure section thereof in a direction towards said joining surface, and a contact positioning part extending from said extension along the joining surface which comes close to front ends of said contacts or in contact with said contacts when said locking device is completely inserted in the housing, thus preventing displacement of said front ends of said contacts.
Claim 2
Dependent Claim
144 words
A locking electrical connector comprising a housing, at least one contact, each contact having a front end matable with other contacts at a joining surface on said connector, and a locking device whose main body is inserted through a side wall of said housing in a direction substantially normal to the side wall, the locking device being engaged with each contact retained in said housing, characterized by the fact that: said main body of said locking device has an extension emerging from the surface of a pressure section thereof in a direction towards said joining surface, and a contact positioning part extending from said extension along the joining surface which comes close to front ends of said contacts or in contact with said contacts when said locking device is completely inserted in the housing, thus preventing displacement of said front ends of said contacts.
Claim 3
Dependent Claim
44 words
The locking electrical connector of claim 1 wherein said contact positioning part, when fully inserted into said housing is positioned adjacent said front end of each of said contacts to substantially prevent movement of said front ends in the plane of said joining surface.
Claim 4
Dependent Claim
68 words
The locking electrical connector of claim 1 wherein said locking device includes lugs engagable with a rear retaining shoulder on each of said contacts upon insertion of said locking device into said housing, engagement of said lugs with said retaining shoulders preventing removal of said contacts through a rear face of said connector, said rear face being on the opposite side of said connector from said joining surface.
Claim 5
Dependent Claim
46 words
The locking electrical connector of claim 3 wherein said pressure section and said lugs are on the main body of said locking device, said contact positioning part extending from said extension parallel to said main body of said locking device, and spaced from said main body.
Claim 6
Dependent Claim
36 words
The locking electrical connector of claim 4 wherein said housing includes a slot extending from said side wall, said main body being received in said slot, said contact positioning part being located along the joining surface.
Claim 7
Dependent Claim
54 words
The locking electrical connector of claim 5 wherein each of said contacts is located in a housing cavity, each housing cavity intersecting said slot, said contact positioning part substantially closing an end of each of said housing cavities on the joining surface of said connector when said main body is inserted into said slot.
Claim 8
Dependent Claim
72 words
The locking electrical connector of claim 1 wherein said contact positioning part includes openings, said front end of each of said contacts being insertable through a respective opening when said locking device is in a first position, each said opening having an edge movable toward said front end of a respective one of said contacts when said main body of said locking device is inserted from said first position into said housing.
Claim 9
Dependent Claim
57 words
The locking electrical connector of claim 7 wherein multiple rows of said contacts are located in said housing, a front end of said contact positioning part, spaced from said openings being shiftable into substantial engagement with contacts in one row when said edges of said openings are shifted into substantial engagement with the contacts in another row.
Claim 10
Dependent Claim
37 words
The locking electrical connector of claim 1 wherein a contact engagement lug is located on said main body, said housing including a housing lance engaging each said contact between said main body and said contact positioning part.
Claim 11
Dependent Claim
23 words
The locking electrical connector of claim 9 wherein said housing lance engages said contact independent of the position of the contact positioning part.
