907,630. Electrical wiring arrangements. SIEMENS & HALSKE A.G. March 31, 1960 [April 10, 1959], No. 11403/60. Class 37. [Also in Group XXII] A wired electrical insulating carrier plate has the electrical wiring anchored in position by positioning the wires on one side of the carrier plate to overlie apertures in the latter and placing clamping elements on the wires also in alignment with the apertures and then driving in the clamping elements so that a portion of the wire is drawn into the apertures under tension. Anchoring discs 1 shaped as shown in Fig. 1 are punched by means of plunger 5 from a metal strip 6, Fig. 5C, and the plunger 5 in the further course of its stroke moves the disc 1 into engagement with the wire 2 overlying the apertures in the insulating carrier plate 3 on support 4. Further movement of the plunger 5 forces the disc 1 and the corresponding portion of the wire 2 into the anchoring aperture; a counter pressure being exerted by a pin 16 so that the arched surface of the disc, caused by the pressure of the plunger 5, is urged into planar form thus causing the disc to expand radially and be securely anchored in the aperture as shown in Fig. 2a. Circuit components such as resistors 8, Fig. 6, are disposed on the side of the carrier plate which faces away from the wiring and their terminal conductors 9 are passed through holes in the carrier plate so as to cross the anchored wire 2 at an acute angle, Fig. 7 (not shown); the components thus being fixed sufficiently in position for subsequent dip or surge-soldering processes. If the holes for the terminal conductors do not lie directly beneath the anchored wiring the terminal conductors 9 are extended to the anchored wiring, Fig. 8 (not shown). |
