Abstract

1409847 Inertia switches; thermal switches; batteries combined with switches TUDOR AB 10 July 1973 [11 July 1972] 32841/73 Headings H1N and H1B An acceleration-responsive switch located in the internal circuit of a vehicle storage battery comprises a pair of fixed contacts 6, 7 a movable contact element 8 biased towards its open position but held in its closed position in contact with the fixed contacts 6, 7 by an overriding spring 10, and a movable mass 16, not directly connected to said spring, mounted for movement in response to predetermined acceleration so that the spring 10 becomes ineffective and the movable contact element 8 moves to its open position. As shown, the switch is in a container 4 which may be integral with a partition 2 between two cells and is closed by the battery cover 3 to provide a receptacle 5 containing oil for spark suppression and to damp the movements of mass 16. Fixed contacts 6, 7 with bridge 8 form the current connection between two adjacent cells. Springs 17 or a diaphragm (24, Fig. 2, not shown) normally centralize mass 16 but in a collision mass 16 impinges upon plate 11 (Fig. 1) causing pin 12 to pivot about the edge of hole 15 and slide off a pin 13 depending from screw cap 14. This allows plate 11 and spring 10 to rise, whereupon spring 9 reasserts to lift contact 8 and open the battery circuit. Removal and replacement of cap 14 resets the switch and closes the battery internal circuit again. In the embodiment of Fig. 3, plate 11 is held by a tube 18 secured to a pin 19 by thermoplastic adhesive and surrounded by a heat coil 20, one end of which is connected to contact element 8 via plate 11 and spring 10, while the other end is connected to an annular contact 21 spaced from plate 11 by an air gap. Ring 16 has insulation 22 and is connected by a lead 23 to the battery at a potential different from that of contact 8. On impact ring 16 engages annular contact 21, coil 20 is energized and melts the adhesive to allow pin 19 to move into tube 18, thus relieving spring 10 and allowing spring 9 to open contacts 6, 7, 8. In a further embodiment (Fig. 4, not shown) the spring 10 is relatively long and tightly wound and movement of the mass 16 buckles the line of the spring reducing its overriding effect to allow a contact bridge (8b, 8c) to leave contacts 6, 7.
