Abstract

A cover 12 is sealed to a can 11 containing for example a capacitor element 9 and has external terminals 18 in protective caps 15 on its upper side. A board or substrate 20 is mounted beneath the cover inside the can and one or more conductive tracks thereon establish connection between the terminals 18 and the capacitor element 9. The substrate 20 is brittle and shatters under physical deformation or thermal shock to break the track(s) to isolate the terminals 18 in the event of excessive pressure build up in the can or overcurrent. In an alternative arrangement. the substrate can be mounted to extend axially of the capacitor element. <IMAGE>

Description

SPECIFICATION Improvements in protective devices for electrical equipment and components The present invention relates, in general, to protective devices for use with electrical equipment and components.
It is known to employ a pressure-sensitive interrupter devices with a capacitor. Such a device then serves to break electrical connection should the interior of a can housing the capacitor be subjected to excessive pressure.
UK patent specification 1592706 describes a known form of such a device.
According to one aspect of the present invention there is provided a device for interrupting an electrically conductive path between a terminal and an electrical component; said device comprising carrier means on which said terminal is mounted and frangible means also mounted to the carrier means for at least partial movement therewith, said frangible means defining at least one electrical conductor for linking the terminal to said component whereby physical deformation of the carrier means and/or excessive current through the conductor beyond a limit will cause the frangible means to destruct thereby to interrupt said conductor.
In the above mentioned application, the carrier means be be a cover or a similar plate-like structure conveniently sealed to a can containing a capacitor element. The carrier means can have two terminals and the frangible means would then provide two conductors, one associated with each terminal, which are connected to the capacitor element. The terminals may be part of terminal assemblies which pass through the cover or carriers means in a sealing relationship therewith. An upstanding conductive pin of each of the assemblies can connect the external terminal to the internal conductor of the frangible means.
Flexible fly-leads can serve to connect the conductors to the capacitor element itself.
Various forms of terminal assemblies can be used such as are described hereinafter.
The frangible means can comprise one or more substrates, such as thin plates or boards made from a ceramic, on which is deposited at least one conductive layer forming the conductor which is interrupted when the substrate destructs. A ceramic substrate as used for thick film integrated circuits is found to be suitable and tends to shatter reliably should the cover be deformed. The cover tends bow outwards should a fault within the can give rise to an abnormal rise is pressure therein and this produces flexure or shear foce on the substrate to cause its physical destruction.
In another aspect the present invention thus provides an improved cover for the can of a capacitor. This cover employs external terminal means and a pressure-sensitive interrupter; said interrupter comprising at least one frangible substrate means carrying one or more electrical conductors which connects the capacitor element to the terminal means, the conductor or conductors becoming broken to disconnect the terminal means from the capacitor element on destruction of the substrate means. The destruction of the substrate means can be caused by deformation of the cover in response to increased pressure in the can. In addition it has been found that excessive current passed through the conductor of te substrate means can of itself create thermal shock sufficient to shatter the substrate means regardless of pressure-response deformation.
The present invention may be understood more readily, and various other aspects and features of the invention may become apparent, from consideration of the following description.
Embodiments of the invention will now be described, by way of examples only, with reference to the accompanying drawings, wherein: Figure 1 is a part-sectional elevation of a device constructed in accordance with the invention; Figure 2 is a plan view of a component of a device shown in Figure 1; Figure 3 is a view corresponding to Figure 1 but depicting the situation where the device is deformed by pressure; Figure 4 is a schematic representation of the component shown in Figure 1 in the situation pertaining to Figure 3; Figure 5 is a plan view of a modified component shown in Figure 2; Figure 6 is a part-sectional elevation of one of the terminals showing an alternative arrangement; Figure 7 is a part-sectional elevation of one of the terminals of one of the devices showing another alternative arrangement; Figure 8 is a perspective view of a further modified terminal means;; Figure 9 is a part-sectional elevation of another embodiment of a device constructed in accordance with the invention; Figure 10 is a view corresponding to Figure 8 but depicting the situation where the device is deformed by pressure; and Figure 11 is a schematic representation of another device constructed in accordance with the invention.
As shown in Figure 1, a device constructed in accordance with the invention, and designated 10, is mounted in superimposed relationship on a container or can 11. The device 10 itself is fabricated separately to the can 11. The device 10 has a recessed cover member 12 sealed to the can 11 at a rim 13.
The can 11 contains a capacitor element 9 which may be of the dry metallised film type or the wet type in which case the can 11 contains, in addition, a dielectric liquid. The cover member 12 serves as a carrier for terminal assemblies 14 which are fitted to the cover member 12. Each terminal assembly 14 has an external cap 15 made from insulating material, preferably synthetic plastics, seated on the exterior supper surface of the cover member 12. A bush 16 is engaged within a hole 17 in the cover member 12. The hole 17 can be formed as a pressing and the bush 16 is in sealing engagement with the surface of the member 12 defining the hole 17. The bush 16, again, made from a synthetic plastics insulating material, has a flange 21 which engages on the inner face of the cover member 12.The upper region of the bush 16 also fits in a recess at the underside of the cap and these components are held together with the aid of a metal pin 19 serving as a conductor.
A conductor plate 20 is held generally parallel to the cover member 12 and below the inner surface of the latter by the pins 19 engaged through the caps 15 and the bushes 16. A U-shaped metallic terminal 18 is located within each cap 15 in a protected position and is also held captive with the associated pin 19. The flanges 21 of the bushes 16 space the plate 20 from the cover member 12. A sheet of insulating material, such as a waxed paper or the like, is interposed between the plate 20 and the flanges 21 of the bushes. The pins 19 are connected electrically to the plate 20 with connections 23. In the construction depicted in Figure 1, each of the pins 19 has heads at both ends and one of these heads can be deformed to spread and clamp the terminal assembly 14 together.It is however possible to provide a screw-threaded portion 31 on the each pin as shown in Figure 6, and to use a nut 30 to clamp the terminal assembly together. It is also possible to unite the terminal assembly 18 with the pins 19 as one-piece components. Figure 7 shows yet another arrangement where the pin has a flange 60 for locating the plate 20 and the lower end of the pin 19 is soldered to the plate 20. This may be desirable per se to form the electrical connection 23.
Figure 2 depicts the plate 20 which is composed of a substrate made from a brittle, frangible material such as a ceramic on which is deposited conductive tracks 25 leading from the connections 23, which may be soldered pads, to further connections 24 again in the form of soldered pads. Flexible leads 26 join the connections 24. to the capacitor element 9 and hence there is a continuous electrical conductive path from each terminal 18 to the capacitor element 9 via the associated pin 19, track 25 and connections 23, 24. A ballast resistor can be incorporated between the conductive tracks 25 on the substrate as shown in Figure 5.
The terminal assemblies can be strengthened by providing interengaging protections 32 on the caps 25 as shown in Figure 8.
During operation, should a fault occur leading to an increase in pressure in the can 11, the cover member 12 becomes deformed as is known and bows outwards as shown in Figure 3. The plate 20 is caused to undergo the same distortion but the stress on the plate 20 actually causes the substrate to break and the conductive tracks 25 are consequently interrupted as denoted simplistically in Figures 3 and 4 by reference 'K'. In practice, the substrate is found more likely to shatter than to break along definite lines. The effect of the breakage is to isolate the terminals 18 from the capacitor element 9. In addition to providing pressure-responsive interrruption, the device is also sensitive to thermal shock when excessive current passes through the tracks 25. In this event the substrate of the component 20 is not distorted mechanically but shatters due to thermal shock.
It is not necessary to employ a single plate 20 nor to the have component 20 arranged to flex with the cover member 12 in order to provide the pressure-responsive interruption.
Figures 9 and 10 depict another device where the like reference numerals denote like parts to the other Figures. In this device, there are two generally upstanding plates 20 each associated with just one terminal 18. The plates 20 are moulded into a fixed bridging piece 45 within the can 11 and to two blocks 42 fitted to the respective pins 19. Each plate 20 provides just one track 25 between the connections 23, 24. As the cover member 12 is deformed by internal pressure, as shown in Figure 10 the blocks 42 tilt apart and move away from the static bridging piece 45 thus breaking the tracks 25 at the zone of separation between the block 42 and the bridging piece 45.
The previously-described arrangements have all employed two terminal assemblies 14 and a single capacitor element 9. In constrast, Figure 11 represents a device with three terminals T1, T2, T3, and associated therewith a can containing two capacitor elements or sections C1, C2. The terminal T1 is common to both elements C1, C2. In this construction, a single frangile conductor plate 20 -or a pair of such plates 20 as in the example of Figures 9 and 10-is associated with the terminals T1 and T2 and functions as previously described to disconnect and isolate the terminals T1, T2 under a fault condition. It is feasible to use a common conductor plate 20 for all three terminals T1, T2, T2 or to use individual plates 20 for all three terminals T1, T2, T3.
