It is sometimes difficult to obtain a reliable electrical connection between the conductors of an insulating panel e.g. a printed circuit board and associated instruments and lights mounted on a motor vehicle dashboard.
In US. patent application Ser. No. 111,421 assigned to the same assignee as the present application, there is described and claim an electrical connector for electrically connecting an electrical component and a conductive track on an insulating panel having an aperture to receive the connector, comprising a body part extruded from resilient electrically insulating material and having generally parallel legs projecting from one of a pair of opposite surfaces of the body part adapted to pass through the panel aperture latchingly to engage the connector and the panel, a bore extending between the opposite surfaces of the body part for receiving the electrical component, and an electrically conductive contact part mounted on the body part overlying at least a portion of of one of the opposite surfaces for contacting a panel conductive track and having a resilient Contact arm to engage a contact element of the electrical component when received in the bore of the body part.
Preferably the contact part overlies the surface of the body part remote from the legs and has two resilient contact arms projecting above that surface and overlying the bore, the ends of the contact part engaging opposite ends of the body part.
It is sometimes desirable to interconnect an electrical component and two conductive tracks on an insulating panel in order that reception of the electrical component in the connector will complete an electrical circuit.
An electrical connector for electrically connecting an electrical component and a conductive track on an insulating panel having an aperture to receive the connector, according to the present invention, comprises, a body part extruded from resilient electrically insulting material and having a pair of generally parallel legs projecting from one of a pair of opposite surfaces of the body part adapted to pass through the panel aperture latchingly to engage the connector and the panel, a bore extending between the opposite surfaces of the body part for receiving the electrical component, and two electrically conductive contact parts mounted on the body part overlying at least a portion of one of the opposite surfaces for contacting a panel conductive track and each having a resilient contact arm extending between the legs of the body part to engage a contact element of the electrical component when received in the bore of the body part.
An electrical assembly according to the present invention comprises a connector, an apertured insulating panel having a conductive track. and an electrical component, the legs of the connector being received in the panel aperture with a contact part of the connector in electrical engagement with the conductive track, and the resilient contacts in electrical engagement with the contact element of the instrument.
The present invention will now be described by way of example with reference to the accompanying drawings in which:
FIG. 1 is a median diagrammatic section of an electrical connector mounted on a board carrying a flat conductor; and
FIG. 2 is a bottom plan view of the electrical connector of FIG. 1.
The electrical connector 10 shown in FIGS. 1 and 2 comprises a body part 11 made from an extruded strip of resilient, electrically insulating material such as polypropylene or nylon, and a pair of contacts 12 formed from a strip of electrically conductive material such as brass.
The body part 11 is generally rectangular in plan view and has a pair of substantially parallel spaced apart legs 17 extending outwardly from one surface 18. Each leg 17 is formed at its free end with an outwardly projecting rib 17a defining a circuit board edge receiving recess 19 between the rib 17a and the surface 18. A through hole 21 extends, at a position between the legs 17, from the surface 18 to an opposite surface 22. Each side of the body part 11 is formed with a pair of spaced apart parallel extensions 20 (FIG. 2) which extend outwardly from the body part 11 and form between them a recess 23 which serves to position a contact 12 on the body part 11.
' Each Contact 12 is formed with a pair of substantially parallel arms 13 and 16. The arm 13 extends between one pair of the extensions 20 and is seated in the recess 23. The free end portion 14 of the contact 12 is of arcuate cross-section and is turned inwardly to cover a part of the surface 18 and to make Contact with a conductor 25 on a board 24. The arm 16 extends through the hole 21 and is held against one wall of the hole 21 by the free end of the arm which is curved outwardly about the free end of the leg 17.
The connector 10 is mounted on a printed circuit board 24 by pushing the legs 17 of the connector through a hole 26 in the board 24. The resilient legs 17 of the connector are bent inwards as the ribs 17a pass through the hole 26 and return to their normal position upon completion of the insertion operation. The connector 10 is thus locked in position on the board 24 by the ribs 17a which also urge the conductor 25 on the board 24 and the intumed free ends 14 of the arms 13 together thus ensuring good electrical contact between the conductors 25 and the contacts 12.
The board 24 can be arranged immediately behind the dashboard (not shown) of a vehicle with the legs 17 of the body part 11 extending towards the dashboard. A capless lamp bulb (not shown) may be positioned in the connector 10 in the board 24 to act as a warning light showing on the dashboard, each bulb Contact being in contact with one of the contact parts 12. A conductive path is thus made between the conductors 25 of the board 24 and the lamp bulb. The connector 10 can alternatively be used to connect a contact pin of an instrument mounted on a vehicle dashboard to a printed circuit board. In this case the two contacts 12 may be used to connect the instrument contact pin to a single conductor 25.
It is possible to reduce the width of the contacts 12 and to displace them laterally, one towards one end of the connector and the other towards the other end so 1. An electrical connector for electrically connecting an electrical component and a conductive track on an insulating panel having an aperture to receive the connector, the connector comprising a body part of generally constant cross-sectional configuration, permitting extrusion thereof, and formed from resilient electrically insulating material, a pair of generally parallel legs projecting from one of a pair of opposite surfaces of the body part, each said leg having a recess for engaging the panel aperture upon passing said legs through the aperture, a bore extending between the opposite surfaces of the body part for receiving the electrical component, and a pair of electrically conductive contact parts mounted on the body part overlying at least a portion of the surface of the body part remote from the legs, each said contact part having a contact surface for contacting a panel conductive track and further having a resilient contact arm extending through said bore between the legs of the body part to engage a contact element of the electrical component when received in the bore of the body part, the free end of the resilient contact arm being curved outwardly away from said bore for engaging a leg of the body part to secure the conductive contact part to the body part.
