The side plates are connected by a bottom piece 25, the rear end of which forms a guide and support end at its lower ends, the plate 11, through which the sleeve 12, tuck 23 for the flat cable 20, whose two conductors are guided, and the bottom piece is designed in such a way that oei 21 are shown. A part is hinged to the bracket by means of two longitudinal plates 58 and 53 in two different axes 24, which part carries two side heights. The lower longitudinal plate 58 is provided with plates 8 and 10, which at the front end in a slotted screw 62 (or optionally with several sections 7 and 9. A screw is in the slots) on a raised section of the Bo-axis 6. At the rear of the denstücks 25 are attached. It carries two pairs of electrical side plates 8 and 10 by a transverse plate Irish clamps 58 and 63, connected at a distance of -11, through which a sleeve 12 is passed, a ° each other and of which the lied in a line at the end of the Cable 13 of the terminals on the flat cable in pairs through conductors 67 under 20 to be connected device 14, for example one of the plate are connected to each other. From the front microphones, records. The wires of the cable 13 whose terminals 58 go to the wires 16 of FIG. 1 are led to a terminal box 15, from which to the block 5 carrying the prongs. The rear two wires 16 come off, one of which is given terminals 63 carry cable lugs 64 to which, if interrupted by a series capacitor 17, the wires 65 of the cable 13 are soldered, which is on. These wires 16 are flexible and end in the outlet end of the sleeve 12 in the interior of the pliers, an insulating block 5 in which it is divided into two branches 66 ( not shown). Conductive inserts are connected to these branches, which, like the wires 65, terminate in metal prongs 18 and 19 if necessary. The block 5 is protected by 3 ° insulating caps.

Then when 40 of a pin 51 is attached to the plate 1. This Fedie pliers is closed, the conductive penetrate which serves to bring the two parts of the pliers automatically into their closed position through the insulating material of the cable,
through, and in each group there is at least one further locking of the pliers in which these prongs are in contact with the corresponding closed position by means of a button 55 in front of conductor 21 of the cable. The prongs are seen for example 45. This button is slidably seated on a rod in the manner 56 shown in Figure 2A or Figure 2B which is secured in an opening 70 of the plate 10; distributed so that a contact between the prongs and he is pressed outwards by a spring 57, and the conductors inevitably takes place, even if the socket attached to it is not very precisely in the guide 23 of the pliers when the flat cable is closed enters an opening 69 of the plate 2, is directed and / or when the two conductors of the 5 °. As a result, in the closed position of the flat cable 20, the pliers are not precisely locked in the cable sheath. To open the pliers it is necessary to have location. The prongs of each group can, like the button 55 against the action of the spring 56 according to FIG. 2A is shown to push in a line obliquely to the inside, so that the bushing from the opening of the guide surfaces of the block 5 is arranged, or 69 exits. Then the constriction on the one as shown in FIG. 2B, with respect to 55 button 55, follow a cutout 71 (FIG. 5) which is distributed over these guide surfaces of the block 5. adjoins the opening 69. If desired, these two representations are of course only intended to apply to the two parts of the pliers in the opened example for the arrangement and number of the electrical position with the help of a further opening, which can be seen from the contact prongs.
