Description
The present invention relates to a battery and contact combination comprising a battery with at least one cell, a plastic casing enclosing said battery, and current collector means.
In previously known batteries, the positive and negative terminals or contact elements project from the battery or are else subject to the athosphere.
If, for example, during the transport of such batte-ries, the contact elements are short-circuited, the battery will be destroyed almost at once. Such a short-circuit may be caused through conducting liquids and metallic objects with which the battery comes into contact.
It is the object of the present invention to eli-minate the above-mentioned disadvantages and ~o pro-vide a battery and contact combination of a new type.
The invention is based on the idea that the battery and contact elements are separate and are, when necessary, connected to each other.
In the combination according to the invention, at least one of the terminals of the battery is arran-ged inside the casing adjacent to its lnner surface, and thecurrent collector means comprise at least one contact element which is arranged to penetr~te said casing and to make contact with said terminal, the combination further comprising clamping elements for clamping said contact element in place.
- By means of the invention substantial advantages are achieved.
The storage time for batteries can be substanti-ally lengthened, especially if hermetically sealed plastic casings are used. Such batteries can be packed, for example, in a metal container without any risk of short-circuit.
The battery can be immersed completely inert, for example, in a conducting salt solution (sea-water) without fear of leakage currents. The her~eticity is maintained even after the contact elements penetrating ~l ~9~SS
the battery casing have been connected to the battery.
By means of the battery according to the invention considerable space is further saved. The battery according to the invention is also mechanically durablè because it has no contact elements which would weaken the construction.
In one aspect of the present invention, there is pro-vided a battery and contact combination comprising a battery with at least one cell, a plastic casing enclosing said battery, and current collector means, at least one of the terminals of the battery being arranged inside said casing close to its inner surface, said current collector means comprising at least one such contact element which is arranged to penetrate said casing and to make contact with said terminal, the com-bination further comprising clamping elements for clamping said contact element in place, the point to be penetrated being weakened and said casing being hermetically sealed.
The invention will now be described in more detail by means of the embodiments according to the accompanying drawings. Thus, the invention is illustrated by way of ex-ample in the accompanying drawings wherein:

In the embodimerlt according to figure 1, a pl~te battery 1 is under the battery surface provided with a terminal plate 2. A weakening 5, which in this case comprises a recess (cf. also figure 5), is made at the terminal plate in a plastic casing consistin~ of two parts 3 and 4. When the casing 3, 4 is sealed accor-ding to figure 2, there are no conducting parts on the battery surface. Contact elements 6, 7 provided with insulated conductors 8, 9 can be inserted into the recesses 5 in the casing 3, 4 (figures 2 and 3).
Each contact element 6, 7 comprises a cassette-shaped plastic or metal housing 16, which is open on one side. In this housing is arranged a pad 17 of resilient material, for example, silicone rubber, which planarly extends somewhat beyond the edge of the cassette 16. In this pad 17 is resiliently embedded a sharp metallic contact pin 18 provided with a flange 19 so that the point Or the pin is visible outside the free surface 20 of the pad 17. The contact pin 18 is galvanically connected to the insulated conductor 8, wh;ch projects out of the cassette 16 and the other end of which can be passed tv the object of use.
In the embodiment according to figure 3, the contact elements 6, 7 are secured inplace by means of a resilient steel strap 10 which presses the contact elements 6, 7 into the recesses 5 in the battery casing 3, 4. The pad 17 of a resilient compound is then somewhat compressed, while exposing the contact pin 18. This pin first penetrates the weakened portion 12 in the plastic casing and thereafter a soft layer 13 in the surface of the battery cell itself, while making contact with the terminal plate 14 of the battery. It is to be noted that said pad of resilient material produces, when the contact element is clamped in place, a hermetic sealing around the contact point (pin). The soft layer in the battery cell may be, for example, bitumen or polyisobutylene.
11'~9455 In the embodiment according to figure 4, the plastic casing 11 is hermetically sealed and made of any suitable plastics material, e.g., foamed poly-urethane, by molding directly around the battery.
In the sea-fishing application according to fi-gure 8, a signal light in a buoy is supplied with energy form a hermetically sealed battery aecording to the invention, whieh battery is suspended on conduetors under the water.
In the battery application according to figures 9 to 13, a plastie casing provided with weakenings is with its batteries mounted in a light signal deviee intended to be floating and arranged to be loosened in eonnection with a life buoy. The light signal device 26 is spherical and transparent in its upper part and eontains two lamps 35 and 36. It is fastened to an L-shaped frame 21 on a rubber support 22 and a fork 23.
Its housing is connected to a life buoy 34 by means of a string 27.
A helical spring 33 (figure 11) continuously presses the contact element against the upper weakenlng in the plastic casing so that the pin 37 penetrates said weakening and a bitumen layer on the surface of the cell, while making contaet with the terminal plate of the battery. In this ease the battery and the plastie easing enclosing it are cylindrical.
In the lower part of the casing the arrangement is such that a corresponding weakened portion is pro-vided with a pad 32 of resilient material which is nearly throughout its thickness penetrated by a pin 31 inserted from outside. The pad 32 is in rest position.
Under a flange 30 adjoining the pin 31 a pushing element 29, which is continuously loaded by a helieal spring 28, is locked in place by means of a eotter 24.
When the signal light device 26, as the life buoy 34 is thrown into the water, is loosened from the frame 21, the string 27 fastened thereto pulls the cotter 24 loose while releasing the pushing element 29 to press 11'~9~55 the contact pin 31, At this moment, this pin 31 pene-trates the weakening 12 in the plastic casing and the insula'ing layer 13 in the cell, while makin~ contact with the terminal plate 14, whereby the circuit is closed ~nd the lamps 35, 36 are lit.
The bottom of the light signal device-26 is pro-vided with an opening covered by a rubber plug 37, and the pushing element 29 is provided with an axial through channel. By inserting a pin or similar through these openings and by pressing it against the flange 30 of the contact pin 31 so that the pin 31 makes contact with the terminal 14 in the battery the functional readiness of the device can be checked without endangering its working order.
Also other constructions can be contemplated within the scope of the invention. Thus, the plastic coating need not be weakened in its contact points.
Instead, it can from the start be made of a material which is thin enough to permit easy penetration by the contact pins. Further, the casing can be intended for penetration from one side only while, on the other side, a metal plate functioning as the second termi-nal of the battery is located in the surface of the casing.
The contact element can also be double-si~ed, i.e. provided with two oppositely directed pins for permitting conncetions between batteries and tapping.
In previously known batteries, the positive and negative terminals or contact elements project from the battery or are else subject to the athosphere.
If, for example, during the transport of such batte-ries, the contact elements are short-circuited, the battery will be destroyed almost at once. Such a short-circuit may be caused through conducting liquids and metallic objects with which the battery comes into contact.
It is the object of the present invention to eli-minate the above-mentioned disadvantages and ~o pro-vide a battery and contact combination of a new type.
The invention is based on the idea that the battery and contact elements are separate and are, when necessary, connected to each other.
In the combination according to the invention, at least one of the terminals of the battery is arran-ged inside the casing adjacent to its lnner surface, and thecurrent collector means comprise at least one contact element which is arranged to penetr~te said casing and to make contact with said terminal, the combination further comprising clamping elements for clamping said contact element in place.
- By means of the invention substantial advantages are achieved.

the battery casing have been connected to the battery.
