Abstract
A plug housing assembly (10) with an outer socket (20), and inner socket (30), a primary latching member (40), a secondary lock member (60) and electrical contact assemblies (80). The inner socket (30) includes contact receiving apertures (34) for receiving latching beams (44) of the primary latching member. The secondary lock member (60) is inserted transversely relative to the contact insertion direction into inner socket (30) so that walls (65a) of contact chamber (65) will engage a sleeve (82) of electrical contact assembly (80), and bottom wall (66a) of latch chamber (66) of secondary lock member (60) will be disposed adjacent to latching beams (44) so that the beams (44) are secondarily locked into place.
Claims9
An electrical plug housing assembly for receiving at least one electrical contact therein and for matable connection with a further electrical housing, said plug housing assembly comprising:
- (a) a housing having at least one contact receiving aperture, a primary latching member, and a housing recess for receiving a secondary locking member;
- (b) said primary latching member includes at least one deflectable latching beam formed thereon, said primary latching member having a free end;
- (c) a secondary locking member disposed in said housing recess, said secondary locking member comprises at least one contact receiving aperture;
- (d) said free end is generally located in the contact receiving aperture of the secondary locking member;
- and
- (e) upon engagement of the free end with an electrical contact inserted through said contact receiving aperture of the secondary locking member, said free end is operative to deflect and move into a locking position relative to said electrical contact within said contact receiving aperture of the secondary locking member.
An electrical plug housing assembly for receiving at least one electrical contact therein and for matable connection with a further electrical housing, said plug housing assembly comprising:
- (a) a socket housing having at least one contact receiving aperture, a primary latching member, and a housing recess for receiving a secondary locking member;
- (b) said primary latching member includes at least one deflectable latching beam formed thereon for providing primary locking of an electrical contact;
- (c) a secondary locking member disposed in said housing recess, said secondary locking member comprises at least one contact receiving aperture, and said secondary locking member is movable in said housing recess between secondary locking and pre-locking positions;
- and
- d) said secondary locking member comprises a secondary locking section, when the secondary locking member is in the secondary locking position in said housing recess said secondary locking section is operative to inhibit deflection of the deflectable latching beam by delimiting movement thereof, thereby providing secondary locking of said electrical contact.
An electrical plug housing assembly for receiving at least one electrical contact therein and for matable connection with a further electrical housing, said plug housing assembly comprising:
- (a) a socket housing having at least one contact receiving aperture, a primary latching member, and a housing recess for receiving a secondary locking member;
- (b) said primary latching member includes at least one deflectable latching beam formed thereon for providing primary locking of an electrical contact;
- (c) a secondary locking member disposed in said housing recess, said secondary locking member comprises at least one contact receiving aperture, and said secondary locking member is movable in said housing recess between secondary locking and pre-locking positions, the direction of movement of said secondary locking member being substantially transverse to an insertion direction of said electrical contact;
- and
- (d) said secondary locking member comprises wall structure comprising a periphery of said at least one aperture thereof, said wall structure is positioned for sliding engagement with a portion of said electrical contact, as said secondary locking member is moved in said housing recess, said wall structure is operative to slidably engage a portion of said electrical contact in said housing recess and thereby move said contact where said contact is in a less than fully inserted position.
