[Class 38 (i)] A rigid sleeve 13 of a tough, stiffly flexible plastic material resistant to flow at normal temperatures and having an " elastic memory," e.g. vinyl acetate-vinyl chloride copolymer, tightly embraces the ferrule 12 of a connector 10. The normal diameter of the sleeve is less than that of the ferrule and the sleeve is expanded mechanically or by heat or soaking in a suitable solvent until it may be slipped on the ferrule to overlap both ends. A bared conductor 20 is inserted in the ferrule and the sleeve 13, which may be coated with adhesive 14, surrounds the insulation. The sleeve diameter is reduced, preferably, by baking, and the connector and conductor are crimped together. The plastic gradually recovers from its deformation by the crimping tool and insulates the ferrule completely. Alternatively, Fig. 8, the sleeve is secured over the upturned back 10b of the connector which is then provided with a spear 25 to engage the conductor 20 which is secured tightly in position by the sleeve which may be shrunk or crimped on to the conductor covering 21. In a further modification, a metal tube 30 is secured by a cement 31 to the sleeve 13 to strengthen it. The ferrule 12 is prevented from opening at seam 17 by the sleeve and the plastic material flows back to cover the crimps A, B. In a still further modification (Figs. 3, 4, not shown), the plastic sleeve may be inserted in the metal sleeve. A suitable solvent is a 5 to 10 per cent tricresyl phosphate in benzene, and a suitable cement is a known composition of vinyl chloridevinyl acetate copolymer with a thermosetting phenol formaldehyde resin and a synthetic polyhydric alcohol-phthalic anhydride resin in a solvent.

Abstract: 247,233. British Thomson-Houston Co., Ltd., (Assignees of Stevenson, A. R.). Feb. 9, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cut - out arrangements; automatic circuit-breakers. -A circuit-breaker is prevented from operating, when the overload it has to deal with is greater than it can safely deal with, by means of a holdon current winding which becomes adequate to maintain the circuit - breaker closed, by itself, only when the overload is, say, ten to twenty times the normal load of the circuit. As shown, applied to a circuitbreaker 13 for a motor 10, the circuit-breaker is normally maintained closed by the voltage winding 17 which normally holds the latch 15 in engagement with the toggle mechanism, against the action of the spring 16. The circuit of the winding 17 includes the contacts of an overload relay 19 energized from a current transformer 20. With ordinary overloads, the overload relay breaks the circuit of the voltage maintaining coil 17 and the circuit-breaker opens. In the event of a short-circuit resulting in a very heavy overload, before the relay 19 can cause the release of the circuit-breaker an additional holding winding 18 energized from the current transformer 20 or, as shown, from a separate current transformer 21 becomes energized sufficiently to maintain the latch in place and prevent the circuit-breaker from opening.
