Abstract: Switching device (1) for the alternating connection of at least one television camera (2) to one of at least two television camera control units (3) or for the alternating connection of at least one television camera control unit (3) to one of at least two television cameras (2); with the switching device (1) having connectors (4, 5) for the television camera(s) (2) and the television camera control unit(s) (3); and each connector (4, 5) having electrical supply contacts (6, 7) for the power and voltage supply of the television camera (2) through the television camera control unit (3); and having at least one optical contact (8, 9) for the transmission of information over fiberoptic cables between the television camera (2) and the television camera control unit (3); and with the switching device (1) having at least one power supply line switch (10) and at least one optical switch (11) and at least one switching control unit (12) to actuate the power supply line switch (10) and to actuate the optical switch (1

Abstract: A jack socket to produce a electrical plug connection with a jack plug includes housing (10) with a space, in which the plug shaft can be inserted; a sleeve contact (20) to contact the contact sleeve of the jack plug; a tip contact (30) with a contact section (32) which, in the inserted state of the jack plug, can be contacted from the contact tip and a tip switching contact (40) with a contact section (42), which, without the inserted jack plug, lies against a tip switching contact contact point of the contact section (32) of the tip contact (30) and is lifted off the contact section of the tip contact (30) during the insertion of the jack plug. The connecting sections (21, 31, 41 51, 61) of the contacts (20, 30, 40, 50, 60) project from an attachment end (14) of the plug housing (10) and have a longitudinal extension.

Abstract: A system for protecting a cable connector, and especially an RJ-45 cable connector, from damage or abuse during use with a chassis receptacle. A cylindrical carrier housing for the connector contains a transverse septum having a shaped opening for receiving and positioning the connector within the housing. A radially-compressible chuck on the cable compresses to grip the cable. A boot on the cable and protrudes from the housing through an overriding bushing threadedly connected to the housing. The boot isolates the cable from flexural stresses. When the bushing is tightened onto the housing, the boot is urged toward the housing, radially compressing the chuck onto the cable. Longitudinal stresses on the cable are therefore isolated from the connector and are transferred instead to the housing. A mating chassis receptacle is receivable of the connector and has an annular groove on an axial face thereof for receiving and rotationally positioning the housing for insertion into the receptacle.
