Abstract
Abstract The locking device 30 is intended for locking contacts 11, and is inserted in the opening 26 made in the side wall 27 of the connector housing 20, which has long and narrow openings 36 made in a back surface 31a of the lower wall 31 of the locking device 30 and extending through its entire width. Inside these openings 36, arms 37 for a fully-locked position are made as an integral part of the locking device which start from the wall in which the openings 36 are formed and extend in a longitudinal direction of the locking device 30. The arms 37 for the fully-locked position are engaged with steps 26a made inside the opening 26, thus preventing extraction of the locking device 30 from the connector housing 20. Reuse of the locking device and increased design freedom for connectors having a locking device inserted through the side wall is therefore possible.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
166 words
An electrical connector comprising a connector housing having a number of contact-accommodating cavities arranged in rows, and a locking device in the form of a frame which is inserted in a first opening in the connector extending across said contact-accommodating cavities, characterized in that at least one second opening is provided in the back surface of a wall section running lengthwise of said locking device, and that at least one latching element is provided for securing said locking device in the first opening and preventing it from being separated from the connector housing, said latching element comprising an integral part of the locking device and extending in the lengthwise direction of said locking device; wherein the lengthwise direction of said locking device inserted in said first opening, extends across said contact-accommodating cavities; wherein said latching element is positioned in said second opening; wherein said locking device includes multiple lengthwise second openings; and wherein said latching element comprises a cantilever locking arm integral with said locking device.
Claim 2
Dependent Claim
166 words
An electrical connector comprising a connector housing having a number of contact-accommodating cavities arranged in rows, and a locking device in the form of a frame which is inserted in a first opening in the connector extending across said contact-accommodating cavities, characterized in that at least one second opening is provided in the back surface of a wall section running lengthwise of said locking device, and that at least one latching element is provided for securing said locking device in the first opening and preventing it from being separated from the connector housing, said latching element comprising an integral part of the locking device and extending in the lengthwise direction of said locking device; wherein the lengthwise direction of said locking device inserted in said first opening, extends across said contact-accommodating cavities; wherein said latching element is positioned in said second opening; wherein said locking device includes multiple lengthwise second openings; and wherein said latching element comprises a cantilever locking arm integral with said locking device.
Claim 3
Dependent Claim
23 words
The electrical connector of claim 1 wherein said second opening extends between a back end and a front end of said locking device.
Claim 4
Dependent Claim
24 words
The electrical connector of claim 1 wherein said latching element constitutes multiple latching elements positioned in said second openings adjacent the back ends thereof.
Claim 5
Dependent Claim
29 words
The electrical connector of claim 3 wherein said locking device includes a lower wall section and an upper wall section, the second openings being in said lower wall section.
Claim 6
Dependent Claim
29 words
The electrical connector of claim 4 wherein partitions join said upper and lower wall sections to define contact throughholes, said contact throughholes being aligned with said contact accommodating cavities.
Claim 7
Dependent Claim
38 words
The electrical connector of claim 5 wherein said locking device includes lugs on said upper and lower wall sections for engaging contacts in said contact-accommodating cavities, only when said locking device is fully inserted into said first opening.
Claim 8
Dependent Claim
38 words
The electrical connector of claim 3 wherein projections in said second openings limit deviation of said latching elements in the up and down direction when said latching elements move towards the front and back of said locking device.
Claim 9
Dependent Claim
19 words
The electrical connector of claim 1 wherein said locking device is shiftable between a temporary-locked position and a fully-locked-position.
Claim 10
Dependent Claim
44 words
The electrical connector of claim 8 wherein said latching elements engage the exterior of said connector housing when said locking device is in the temporary-locked position and engage an interior surface of said connector housing when said locking device is in said fully-locked position.
Claim 11
Dependent Claim
27 words
The electrical connector of claim 9 wherein said latching elements are deflectable to permit the locking device to move between the temporary-locked position and the fully-locked position.
Claim 12
Dependent Claim
37 words
The electrical connector of claim 10 wherein said locking device includes temporary-latching arms for engaging said connector housing in the temporary-locked position, the temporary-latching arms and the latching elements holding said locking device in the temporary-locked position.
Claim 13
Dependent Claim
19 words
The electrical connector of claim 11 wherein said temporary-latching arms are located on opposite ends of said locking device.
Claim 14
Dependent Claim
16 words

Claim 15
Dependent Claim
41 words
The electrical connector of claim 1 wherein said locking device is shifted into said first opening to a fully-locked position and said latching element extends transversely relative to the direction in which said locking device is shifted into said first opening.
Claim 16
Dependent Claim
16 words
The electrical connector of claim 1 wherein said connector includes housing lances in each contact-accommodating cavity.
Claim 17
Dependent Claim
38 words
The electrical connector of claim 15 wherein said housing lances comprise primary-locking members for holding contacts in said contact-accommodating cavities as said locking device defines a secondary-locking device when positioned in a fully-locked position in said first opening.
