An electrical pressure contact device includes a sleeve with a first end and a second end. A contact head is slideably mounted in the sleeve and has a first end protruding from the sleeve and a second end located in the sleeve. A connecting piece has an inner portion connected to an inner wall of the sleeve and an outer portion protruding from the second end of the sleeve. An axially extending bore in a first piece located in the sleeve receives an elongated member of a second piece. A band has a plurality of inwardly arching lamellae and is located in the bore. The elongated member is inserted in the band so that the lamellae rub against the elongated member. A biasing element in the sleeve surrounds the elongated member and urges the contact head away from the sleeve.

Electrical pressure contact

The invention relates to a fluid-tight, in particular oil-tight, cable duct () with a duct body (), includes an inner side (), exposed to a fluid, an external side () separated from the fluid and at least one cable channel (), through which at least one electrical line () formed by a flex is run from the inner side () to the outer side () of the duct body (). A seal element () is arranged in the cable channel () with a number of individual channels () passing therethrough which corresponds to the number of lines and through which the lines () run individually. The lines () are each formed from two line sections, connected by an electrically-conducting connector piece () with a solid cross-section, whereby the connector piece () is housed within the single channel of the sealing element (), at least over a part of the length thereof.

Fluid-tight cable duct

An electric contact coupling for connection of a first group of electric conductors to a second group of electric conductors, and especially for use in the coupling of rail and other vehicles with one another, comprises a first plug contact carrier and a second socket contact carrier which are movable into assembly with one another to bring the plug contact elements of the first contact carrier into electric contact with the socket contact elements of the second contact carrier. The two contact carriers are arranged in respectively associated contact carrier housings. The first contact carrier is movable by a positioning mechanism axially relative to its housing to bring its contacts into engagement with the contacts of the second carrier after the two carrier housings have been brought into engagement with one another. Transversely movable closure members seal the carrier housings against the penetration of dirt and moisture when the carrier housings are uncoupled from one another. The support for the two contact carriers in a coupled condition of the coupling is such that reasonable movement of one carrier housing relative to the other is accommodated without substantial loading of the contact elements to avoid damage to the elements. The contacts automatically clean themselves during the coupling procedure.

Electric contact coupling

An electrical pressure contact includes a housing sleeve with an end facing the contact and an end facing away from the contact, a contact pin axially slidably supported in the housing sleeve, which pin extends out of the housing sleeve at the side facing the contact, which pin is a pushable into the housing sleeve against the biasing force of the a biasing element arranged in the housing sleeve, and through the conductive body of which pin the electrical contact is made, a terminal piece for fastening to an electrical supply conductor at the end of the housing facing away from the contact, and an axially flexible electrical conductor arranged in the housing sleeve between the terminal piece and the contact pin. The flexible electrical conductor is at its end facing the contact clamped into an axial bore formed in the end of the contact pin facing away from the contact and at its end facing away from the contact is clamped in an axial bore formed in the end of the terminal piece facing the contact.
