Abstract
Abstract A plug-in cable connector comprises an optional number of plate-shaped contact carrier modules that are provided with defining walls which partially close the duct-shaped chambers of the modules in a mirror-image fashion. In connection with the provision of a stop shoulder on a contact carrier module on one hand and the incorporation of half walls in the module carrier casing on the other hand, each of the modules may be individually inserted in an operative manner into the casing, forming a self-contained enclosed unit.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
221 words
A plug-in cable connector for producing an external electrical connection with a contact strip comprising: a strip casing (1) including blade contacts (2) comprising a module carrier casing (14) for accommodating an optional number of plate-shaped contact carrier modules (3) each of which has, in series one behind the other, an optional number of duct-shaped chambers for respectively accommodating a spring contact, said contact carrier modules (3) being provided with defining walls (4 and 5) partially closing the duct-shaped chambers (6), in a mirror-image fashion, in such a manner that on one side, the upper half of the contact carrier module (3) is closed, and on the other side the lower half of said contact carrier module is closed, and one of defining walls (4 and 5) forms with side walls (9) standing back relative to the defining wall (5) of the duct-shaped chambers, a shoulder (13), the module carrier casing (14) being provided with half-height walls (16) forming chambers (15) which form a stop means for the shoulders (13) of the contact carrier modules (3) in such a manner that the wall (5) of the contact carrier module forming the shoulder and the side wall (9) of the module carrier casing complement one another to form an intermediated wall extending over the entire height of the contact carrier module (3).

Claim 3
Dependent Claim
53 words
A plug-in cable connector according to claim 1 or claim 2, wherein spring legs (18) of the spring contacts (8) are provided with lateral guide cams (7) guided on the side walls (9) of the chamber (6), thus serving to center (19) the spring contacts in the chamber. of claims 1 to 3,
Claim 4
Dependent Claim
69 words
A plug-in cable connector according to any one of claims 1 to 3, wherein an insulation displacement zone of the spring contacts (8) is formed by a pair of punched tabs (21 and 22) which are bent in a U-shape and enclosing a slot (20) with blade edges, the central legs (21) of the punched tabs forming with the lateral legs (22) an obtuse angle of more than 90°.
Claim 5
Dependent Claim
20 words
A plug-in cable connector according to claim 4, wherein the contact is provided with clamp tabs (23) as insulation crimps.
Claim 6
Dependent Claim
70 words
A plug-in cable connector according to any one of claims 1 to 5, wherein the module carrier casing (14) is provided with mounts for attachment of a metal plate (26) as electrical screening, and which is provided on one side with windows (28) co-operating with corresponding cams (27) on the contact carrier casing, and on the other side with resilient tabs (29) as an electrical connection to a zero conductor.
Claim 7
Dependent Claim
131 words
A plug-in cable connector according to any one of claims 1 to 6, wherein the module carrier casing (14) is located in a two-part plug casing (30 and 31), one portion (30) of which is provided with an external window-like recess (33) having lateral slots (32) with an internal cavity for attachment of a clamp as a plug strain relief means, which is formed by a U-shaped bow (35 and 36) insertable from the outside through the slots (32), with lateral legs (36) ribbed on the inner side, and by a clamp plate (39) insertable into the internal cavity having slots (38) defined by exposed spring tongues (37), into which slots (38) the lateral legs (36) of the U-shaped bow are inserted, wedging the exposed spring tongues (37) in their ribbing.
