Abstract

An electrical assembly comprising a first component (10) presenting predetermined regions (A,B) secured to respective ones of corresponding connections (32) presented by a second component (30), the predetermined regions (A, B) being initially electrically connected to one another through at least one part (26) of the first component (10) which is capable of being broken so that the predetermined regions (A, B) would then be electrically connected to one another just through the second component (30), thereby enabling the electrical assembly to be small yet easy to manufacture.

Description

Electrical Assemblies
The present invention relates to electrical assemblies by which is meant assemblies formed from electrical ^ 5 components which in this context also includes electronic components.
It is well known that, in general, there are benefits to be gained in terms of cost and convenience if an electrical assembly is of small size and is easy to
10 manufacture, but these benefits are often found to be mutually exclusive.
According to the present invention, however, an electrical assembly comprises a first component presenting predetermined regions secured to respective ones of 15 corresponding connections presented by a second component, the predetermined regions being initially electrically connected to one another through at least one part of the first component which is capable of being broken so that the predetermined regions would then be electrically 20 connected to one another just through the second component. Preferably, the first component is initially manufactured in one piece of an electrically conductive material and may be a terminal, and the second component is of a conventional construction and may be a diode. 25 Although it should be appreciated that many modifications are possible, in which one or more of the following features are omitted, a particularly preferred embodiment of an electrical assembly according to the present invention includes all of the following features: 30 a) the predetermined regions are co-planar and separated from one another by a gap; "• b) the predetermined regions are pre-tinned to facilitate soldering, particularly hot air soldering; - c) the predetermined regions are located on a base
35 portion alongside at least one flange-like side portion; d) the first component is of channel outline and the second component is received within the channel outline; e) the first component is shaped to facilitate electrical connection to at least one further electrical component, particularly an electrical connection involving a resilient deformation; and f) the first component is shaped to facilitate mechanical connection to a support.
An electrical assembly, in accordance with the present invention, will now be described in more detail, by way of example only, with reference to the accompanying drawings, in which:-
Figure 1 is a plan view of the electrical assembly before use;
Figure 2 is a side view looking from the right side of Figure 1; Figure 3 is an end view looking from the lower end of Figure 1; and
Figure 4 is a partly sectioned side view similar to Figure 2 but showing the electrical assembly in use.
In the accompanying drawings, a first component 10 is initially formed in one piece of phosphor bronze, having been stamped and bent to the illustrated channel-like outline.
There is a base portion 12, one end of which includes two slits 14 allowing a tongue 16 of the base portion 12 between the two slits 14 to be resiliently deflectable to facilitate mechanical connection to a support, with a gap
18 being formed near the other end of the base portion 12.
There are two side portions 20, one end of each of which has a leg 22a and 22b so that they together form a resiliently deflectable connection for a component such as a lamp, and the other end of each of which has a slit 24a and 24b to permit electrical connection with an electrical wire by localised removal of electrical insulation from the electrical wire. The inside surface of the base portion 12 between the two side portions 20 is pre-tinned at two predetermined regions A and B on opposite sides of the gap 18. In alignment with the gap 18, each of the two side portions 20 is formed as or with a weakened or frangible connection 26 which can be broken.
) Offset from the two connections 26, further tongues 28
\ 5 similar to the tongue 16 are formed to further facilitate mechanical connection to a support.
To form the electrical assembly, a second component 30 such as a diode is inserted into the first component 10 in the direction of arrow C so that a pair of connections 32 10 presented by the second component 30 can be respectively secured to the predetermined regions A and B of the first component 10, preferably by hot air soldering.
In a preferred application of the electrical assembly, although other applications are possible in for example
15 connectors and switches, the first component 10 with the second component 30 already secured thereto is fastened to a plastics lampholder body 34.
The tongue 16 snap engages in an appropriate aperture
36 presented by the body 34 to permit mechanical
20 connections, whereas the legs 22a and 22b and the slits 24a and 24b are accessible through appropriate openings 38 presented by the body 34 to permit electrical connections.
The weakened or frangible connections 26 are then broken so that electrical connection between the
25 predetermined regions A and B, and thus the upper and lower ends of the first component, is through the second component.
The connections 26 can be broken by pushing a tool through aligned slots 40 (one shown) in the body 34.
30 If there is no need for the second component, the weakened or frangible connections 26 are left intact so
■ that electrical connection between the predetermined regions A and B, and thus the upper and lower ends of the first component, is maintained through the side portions
35 20.
The hot air soldering could be replaced by mechanical or welded joints between the first and second components.
