Cable terminal device for transmitting electrical drive power
View Patent ↗A terminal device has a housing of insulating material, the housing surrounding a portion of the cable end of a sleeve and having a flange directed towards a terminal receptacle. There is additionally provided an inner shield sleeve of conductive material arranged in the housing and surrounding the cable, the inner shield sleeve is connected conductively to a shield of the cable and which has a flanged contact zone directed towards the terminal receptacle. Fastening screws are used simultaneously to press the housing and the flanged contact zone, resting on the housing, of the inner shield sleeve axially against a shield housing of the terminal receptacle.
1. A cable terminal device comprising:
a housing of insulating material, which surrounds an end portion of a cable in the form of a sleeve and which comprises a flange directed towards a terminal receptacle;
an inner shield sleeve of conductive material arranged in the housing and surrounding the cable, the inner shield sleeve being connected conductively to a shield of the cable and having a flanged contact zone directed towards the terminal receptacle;
an outer shield sleeve surrounding the cable, the outer shield sleeve being arranged in the housing and being pushed onto a cable-side end of the inner shield sleeve, the shield of the cable being fixed by clamping between the inner and outer shield sleeves; and
fasteners, by which the housing and the flanged contact zone of the inner shield sleeve, resting on the housing, simultaneously press axially against a conductive shield housing of the terminal receptacle.
2. The cable terminal device according to claim 1 , wherein the outer shield sleeve takes the form, on the cable side, of insulation crimping for the cable and, in the area where the shield of the cable is clamped firm, of shield crimping.
3. The cable terminal device according claim 2 , wherein a sealing arrangement is provided, which comprises a seal and a covering cap, which surround the cable, the inner shield sleeve, the outer shield sleeve, and the seal being press-fitted into the cable-side end of the housing and the covering cap surrounding the seal and the cable-side end of the housing, the covering cap capable of being latched to the housing.
4. The cable terminal device according to claim l, wherein a second sleeve-shaped seal is provided, which is screwed in such a way onto a shoulder of the housing formed in the area of the flange that it rests sealingly between the shoulder and a sealing face formed on the terminal receptacle on fastening an inner conductor of the cable to the terminal receptacle.
5. The cable terminal device according to claim 1 , wherein the flanged contact zone of the inner shield sleeve comprises contact points and/or disc-or arm-shaped contacts.
6. The cable terminal device according to claim 1 , wherein at least one fastening screw arranged axially in the area of the flange of the housing is provided as a fastener.
7. The cable terminal device according to claim 1 , wherein at least one snap-action hook arranged axially in the area of the flange of the housing is provided as a fastener.
8. The cable terminal device according to claim 1 , wherein a cable lug crimped onto the cable comprises a terminal part directed towards the terminal receptacle, the terminal part configured to connect with a current-carrying part of the terminal receptacle in a screw area.
