CABLE PORTION AND COMMUNICATIONS EQUIPMENT FOR CONNECTING SUBSCRIBER LINES TO A DATABUS LINE

摘要

A cable portion comprising a databus line (54) having one or more subscriber lines (52) connected thereto by a coupler device. The databus line and the subscriber line(s) each comprise a twisted pair of conductors protected by shielding. The coupler device comprises a coupler (53) providing data transmission between the two parts of the databus line and between the databus line and the subscriber line(s), and connectors (56A, 56B, 58) serve to connect the databus line with the subscriber line(s) in reversible manner. The coupler device presents weight of less than 70 g and is held by means of a fastener collar that enables the cable portion to be put into place in particularly practical manner in order to constitute a data transmission circuit.

主权项

1. A cable portion comprising:
two parts of a databus line; at least one subscriber line part; and a coupler device to which said databus line and subscriber line(s) parts are connected; the databus line and the at least one subscriber line each comprising a twisted pair of conductors protected by shielding; the coupler device comprising:
in a conductive housing, a coupler for transmitting data between the two parts of the databus line, and also between the databus line and said at least one subscriber line; andconnectors secured to the housing, enabling the two parts of said databus line and said at least one subscriber line to be reversibly connected thereto; the housing being electrically connected to the shielding of said two parts and of said at least one subscriber line; the coupling device weighing less than 70 g and being held with the help of a fastener collar.
