615,737. Direct connections between conductors; junction-boxes. OORTGIJSEN, J. Dec. 18, 1945, No. 34248. Convention date, March 14. [Class 38 (i)] A connector for joining two or more conductors 7, 8, 9 comprises resiliently-mounted members 1, 2 forming a gap 3 into which the conductors are forced and subsequently retained in electrical connection so that in forcing the conductors into the gap they are scraped clean and local plastic deformation of either the conductors or the connector members is effected' to give a good contact surface. The two members 1, 2 are provided with shaped edges and cutting edges 10 which remove the insulation, the shaped edges penetrating the conductors. The gaps 3 and the profiles of the shaped edges may be of varying widths to accommodate conductors of different gauges and of different insulation thicknesses. The profiles of the shaped edges may be of triangular, semicircular or other form. In a modification, Fig. 4, the connector comprises series of members 1, 2, the gaps between which are of variable width. In a further modification, Fig. 6, the members 1, 2 are of circular formation having projections which are relatively staggered to accommodate the conductor 5. In a still further embodiment, the connector comprises a base 19, Figs. 24, 25, 26, having projections and accommodating a loose plug 17, also having projections which co-operate with the projections on the base for making connection with and securing the conductors. In another form, Fig. 35, the connector consists of a resilient unit having gaps 3 for connecting one core 27 of a four-core cable with a branch wire (not shown). The connector may be enclosed in an envelope of insulating material which may also enhance the resiliency of the members 1, 2 (Fig. 19, not shown). The envelope may be filled with a sealing substance. In further modifications, one conductor of hard material may act as one member of the connector ; the connector may be made of preshaped material; the co-operating members may be off-set from one another at their tops; and two or more gaps may be provided separated by pins which extend the whole gap lengths (Figs. 10, 13, 17, 18, 32, not shown). The connector may be used for making electrical connections in junction-boxes, to bus-bars and to other electrical apparatus (Figs. 33, 34, 37, 38, not shown). The Specification as open to inspection under Sect. 91 comprises also a connector arranged longitudinally along the conductor (Figs. 35, 36, 37, Cancelled, not shown). Springs of different strength may be brought into operation successively depending on the widtli of the gap (Fig. 22, Cancelled, not shown). The connector may also be used with a contact finger for a drum controller (Figs. 41 to 43, Cancelled, not shown). This subject-matter does not appear in the Specification as accepted.
