US 5,496,194 A · Electrical connector with two stage latch having improved retaining means

Abstract

An electrical connector is disclosed having a movable contact retainer that cooperates with the connector housing to either retain or release the contacts. The retainer in movable from a closed position where the contacts are secured in place with respect to the connector housing and to an open position where the contacts are free to be removed for repair or replacement. A latch mechanism is provided that is operable from outside of the connector to move the contact retainer to either of its two positions. The latch mechanism includes a latch lever having a raised surface that, when depressed flush with a surface on the connector housing by means of a tool and pushed in the appropriate direction, is made to move from its closed position to its open position. The latch lever includes a camming surface that engages a portion of the connector housing to automatically cam the latch out of the way when moving in the opposite direction, therefore, the retainer can be returned to its closed position by simply pushing the extended retainer back into the housing.

Dependent claims

An electrical connector having:

(a) a housing;
(b) a plurality of contacts insertable in a first direction into said housing;
(c) a retainer movable in a second direction opposite to say first direction for retaining said contacts in said housing and movable in said first direction for releasing said contacts so that said contacts are removable from said housing;
and
(d) a retainer latch associated with said retainer comprising:
an opening in said housing extending through a floor of a recess in an outer surface of said housing and having a first enlarged portion and a necked down portion of said opening;
and
a latch attached to said retainer and resiliently biased into latching engagement with said first enlarged portion of said opening upon movement of said retainer in said second direction into a latched position to retain said contacts in said housing, said latch being manually movable from said outer surface of said housing and arranged so that when said latch is depressed in opposition to said resilient bias and moved in said first direction, a portion of said latch is moved from said first enlarged portion into said necked down portion of said opening and said retainer is moved in said first direction thereby releasing said contacts.

An electrical connector having:

(a) a housing;
(b) a plurality of contacts insertable in a first direction into said housing;
(c) a retainer movable in a second direction opposite to said first direction for retaining said contacts in said housing and movable in said first direction for releasing said contacts so that said contacts are removable from said housing;
and
(d) a retainer latch associated with said retainer comprising:
an opening in an outer surface of said housing, said opening having a first enlarged portion, a second enlarged portion, and a necked down portion arranged so that said necked down portion of said opening is disposed between said first and second enlarged portions;
and
a latch attached to said retainer and resiliently biased into latching engagement with said first enlarged portion of said opening upon movement of said retainer in said second direction into a latched position to retain said contacts in said housing, said latch being manually movable from said outer surface of said housing and arranged so that when said latch is depressed in opposition to said resilient bias and moved in said first direction a portion of said latch is moved from said first enlarged portion into said necked down portion of said opening and said retainer is moved in said first direction thereby releasing said contacts, and as said latch is further moved in said first direction, said portion of said latch moves past said necked down portion of said opening and said latch is urged into latching engagement with said second enlarged portion of said opening by said resilient bias.
