Definitions
- This invention relates to a lamp assembly of the type comprising an electrically insulating hollow body, a plurality of bulbholders, at least one contact blade for each bulbholder and a plurality of spaced, electrically conductive elements, cut from an electrically conductive sheet and each extending between a location in the body at which an electric supply connector is attached to the assembly in use and a respective location in the body adjacent to a respective bulbholder, each contact blade having a blade portion within the bulbholder and a flat portion externally of the bulbholder extending parallel to and abutting one of said electrically conductive elements.
- Patent Specification No. GB-A-2005001 discloses a lamp assembly of this type, in which each contact blade has a projecting part which is an interference fit in a recess in the insulating body and thus holds the contact blade in place.
- the electrically conductive elements have apertures therein for receiving spigots which project from the insulating body and are heat deformed after assembly to hold the conductive elements in place.
- the present invention provides a single attachment formation for each contact member which also serves to secure the associated conductive element to the insulating body.
- the insulating body has a respective projection for securing each blade contact and its associated electrically conductive element thereto, with the formations on such blade contact and electrically conductive element each comprising an aperture through which the projection extends, the formation on the one of said blade contacts and said electrically conductive element further from the insulating body comprising barbs adapted to engage with said projection to resist withdrawal.
- each contact blade and its respective electrically conductive element may be formed by a second blade portion which extends from the flat portion of the contact blade at an angle thereto and engages with a corresponding blade portion similarly extending from the electrically conductive element.
- Recesses may be provided in the insulating body for accommodating each such second blade portion and corresponding blade portion, one of which is resiliently biased to press against the other blade portions which, in turn, is pressed against a wall of the recess.
- the lamp assembly comprises an electrically insulating, hollow moulded plastics body 10 (only partially shown in the drawings) which is of generally dish form having a rectangular gase 12 and upstanding walls 14. Integrally moulded with the base 12 are five tubular elements each constituting the electrically insulating part of a respective bulbholder 16.
- Extending over the otherwise open face of the base 12 are six electrically conductive elements 18 to 23 all formed from the same mild steel sheet. Briefly the sheet is pierced to define the electrically conductive elements 18 to 23 but leaving parts 24 of the sheet metal unpierced so that the electrically conductive elements are held in the required relative dispositions. After the pierced blank has been inserted in a die, the joining parts are removed and the plastics body 10 is offered up to the die so that the electrically conductive elements are retained in position thereon in a manner to be described hereinafter.
- the electrically conductive element 18, which serves as a common return path for all five bulbs, has a respective opening 26 aligned with each of the bulbholders 16.
- upturned portions 28 and 30 are disposed at diametrically opposite locations on the edge of each opening 26 and each contains a respective opening 32 for receiving the lateral pins 34 ( Figure 2) of the bayonet cap of a bulb 36.
- each bulbholder 16 Associated with each bulbholder 16 is a respective spring contact blade 38 having a first blade portion 40 within the bulbholder 16 and engaging with the centre contact of the bulb 36.
- Each contact blade also has a intermediate flat portion 42 and a second blade portion 44 which extends into a rectangular recess 46 disposed adjacent to the corresponding bulbholder 16.
- a rectangular opening is formed in the flat portion 42 in order to accommodate a projection 48 which is moulded integrally with the plastics base 12.
- the contact blades 38 are positioned on the plastics body 10 before it is offered up to the die containing the electrically conductive elements 18 to 23.
- Each such element has at least one rectangular aperture, such as the aperture 50 in the element 22, provided with inwardly directed barbs 52 and 54 which engage with opposite sides of the projection 48.
- Adjacent to the aperture 50 a tongue 56 is stamped out of the element 18 and bent downwards so as to be insertable into the recess 46 where it engages between one of the walls thereof and the second blade portion 44.
- the engagement of the bars 52 and 54 with the projection 48 not only serve to retain the conductive element 22 in position but also enable it to hold the contact blade 38 in place as can be seen in Figure 3, a second projection 58 is formed on the base 12.
- the projection 58 is engaged by barbed projections 60 and 62 formed on the edges of an opening 64 in the conductive element 18.
