Abstract
Abstract A multicontact plug and socket is suggested which comprises a plug strip (2) with flat plug-in contacts (3) and a socket (1) with assigned flat contact receptacles (11) which are arranged in parallel chambers (8) of a contact carrier (5, 6, 7) and extend through assigned openings (10) of a safety plate (9) which is arranged so as to be displaceable in the contact carrier (5, 6, 7) in order to lock the contact receptacles (11). A catch tongue (15) of every contact receptacle (11) engages at the plate side (21) facing in the plug-in direction of the socket (1) in the unlocking position of the plate (9), while edge areas (20; 47, 48) of the opening (10) of the plate (9) contact portions of the edge (16) of the box-shaped portion (13) of the contact receptacles (11) with the plate side (21) in the locking position of the plate (9).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
Multiconnection plug and socket comprising a plug strip which is provided with plug-in contacts, and a socket which includes a contact carrier having a plurality of parallel chambers, contact receptacles inserted into the flat chambers, respectively and each receptacle having a box-shaped portion formed with a resilient cantilivered catch tongue, the contact receptacles passing through assigned openings in a safety plate which is displaceable in the contact carrier transversely to the flat chambers, the safety plate having projections each projecting into one of the opening and a side of the safety plate facing in a plug-in direction of the socket lies substantially in the plane of end edges of respective said box-shaped portions, the safety plate being transversely displacedable between an unlocking position in which the catch tongues of the contact receptacles engage the projections in the chambers, and a locking position in which the plate side engages at least a part of respective said end edges of the box-shaped portions to safeguard the contact receptacles against tilting.
Claim 2
Dependent Claim
168 words
Multiconnection plug and socket comprising a plug strip which is provided with plug-in contacts, and a socket which includes a contact carrier having a plurality of parallel chambers, contact receptacles inserted into the flat chambers, respectively and each receptacle having a box-shaped portion formed with a resilient cantilivered catch tongue, the contact receptacles passing through assigned openings in a safety plate which is displaceable in the contact carrier transversely to the flat chambers, the safety plate having projections each projecting into one of the opening and a side of the safety plate facing in a plug-in direction of the socket lies substantially in the plane of end edges of respective said box-shaped portions, the safety plate being transversely displacedable between an unlocking position in which the catch tongues of the contact receptacles engage the projections in the chambers, and a locking position in which the plate side engages at least a part of respective said end edges of the box-shaped portions to safeguard the contact receptacles against tilting.
Claim 3
Dependent Claim
103 words
Plug and socket according to claim 1, characterized in that each plate opening (10), to which one said contact receptacle (11) is assigned, is adapted to the cross section of the box-shaped portion (13) of the assigned contact receptacle (11), and a respective said projection (20), which projects into the opening (10), is formed on a wall of the opening (10) and extends parallel to a locking direction of the plate (9), the catch tongue (15) of the assigned contact receptacle (11) engaging behind the projection (20) so as to contact the plate side (21) in the unlocking position of the plate (9).
Claim 4
Dependent Claim
68 words
Plug and socket according to claim 2, characterized in that each projection (20) contacts a portion of the edge (16) of the box-shaped portion (13) of the assigned contact receptacle (11) in the plate of the plate side (21) in the locking position of the plate (9), while an edge portion of the plate opening (10) contacts another portion of the edge (16) of the contact receptacle (11).
Claim 5
Dependent Claim

Plug and socket according to claim 5, characterized in that the larger and smaller contact receptacles (25; 11) contact the plate side (21) with their catch tongue (29; 15) in the unlocking position of the plate (9), wherein the catch tongues (29; 15) of the contact receptacles (25; 11) project transversely relative to a locking direction of the plate (9) at the box-shaped portions (28; 13) of the contact receptacles (25; 11).
Claim 8
Dependent Claim
138 words
Plug and socket according to claim 5, characterized in that the catch tongues (29) of the larger contact receptacles (25) project in a locking direction of the plate (9) portion (28) of the at least one larger receptacle (25) and are engaged at undercuts (27) of the contact carrier (23, 26; 42) in the unlocking and locking positions of the plate and the plate side (21) contacts the edge portions (49) of the box-shaped portions (28) in the locking position, while, in the unlocking position, the smaller contact receptacles (11) contact the plate side (21) with their catch tongues (15) projecting transversely relative to the locking direction and, in the locking position of the plate (9), portions of the plate side (21) contact the edge portions (16) of the box-shaped portions (13) of the smaller contact receptacles (11).
