(ORIGINAL)
Name of Applicant: Robert Bosch GmbH of ZGE/ZGM Central Postfach 30 02 D-70442 Stuttgart Germany Actual Inventor(s): Address for Service: Invention Title: The following statement is a performing it known to us: DAVIES COLLISON CAVE, Patent Attorneys, 1 Little Collins Street, Melbourne 3000, Victoria, Australia "Connector for an electric motor" full description of this invention, including the best method of -1- Q\OPER\D{DEC '00\PIR00I CAP DOC 6/12/00 P. PER\D236485-lsp I.d -2- CONNECTOR FOR AN ELECTRIC MOTOR Field of the Invention The present invention relates to a connector for an electric motor particularly for electrically connecting an electric motor to a printed circuit board.
Background of the Invention It is known in the automotive industry to electrically couple an electric motor, for use in an air conditioner unit or the like, to a printed circuit board (PCB) via individually soldered wiring. Such wiring is, however, generally time consuming and labour intensive to i connect. It has recently been proposed to mount the motor directly to the printed circuit board to allow for direct electrical coupling between the motor and the board but vibration 15 of the motor can lead to unacceptable stress between electrical contacts coupled to the terminals of the motor and the board itself.
Object of the Invention g 20 The present invention seeks to provide a connector to address the above problems.
o i Summary of the Invention In accordance with the invention, there is provided a connector for electrically coupling a terminal of a device to a substrate, the connector having: a base portion for connection to the substrate; a coupling portion for clamping engagement and electrical connection with the terminal; and a flexible linkage to accommodate positional variation between the substrate and the terminal, wherein the flexible linkage projects away from the base portion, when connected to the substrate, and is bent over at a location adjacent the insertion P %OPERD)'F236485"-sraI dc.
-3space such that the coupling portion extends in a direction back toward the substrate.
Preferably, the coupling portion includes resiliently biased members separated by a slot and arranged to receive the terminal therebetween.
Preferably, the flexible linkage includes a pair of arms projecting from the base portion, for supporting the coupling portion, each arm joining with a respective member.
Preferably, the arms include an insertion space therebetween for initial receipt of the terminal, the insertion space tapering toward the slot.
Preferably, the members are joined to define a closed end of the slot.
15 Preferably, the base portion includes at least one contact lug projecting therefrom for connection to the substrate by soldering.
Preferably, the at least one contact lug is formed by deformation from a main body of the base portion.
S"Preferably, the connector is formed from a unitary blank of sheet metal.
eeoc• Brief Description of the Drawings The invention is described, by way of non-limiting example only, with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a connector; and Figure 2 is a perspective view of a unit with electric motors coupled to a PCB via connectors formed in accordance with the connector of Figure 1.
P:NOPERK m p&W17 c p doc.O6/I2J -4- Detailed Description of the Drawings A connector 1 includes a base portion 2, a coupling portion 3 and a flexible linkage 4. The coupling portion 3 is formed of two members 5, 6 which have a slot 7 extending therebetween and which are joined together to define a closed end 8 of the slot 7.
The members 5, 6 are integrally formed with respective arms 9, 10 of the linkage 4. The arms 9, 10 are separated by a slot 7a, opposite the slot 7, and by an insertion space 11 adjacent the coupling portion 3, which tapers toward the slot 7. The linkage 4 and coupling portion 3 are connected so as to form a generally inverted shape, with the arms 9, 10 projecting away from the base portion 2 and being bent over adjacent the insertion space 10 so that the coupling portion 3 extends in a direction back toward the .oo.
base portion 2.
15 The base portion 2 includes three lugs 12, 13 and 14 which project from a main body therefrom to form electrical contacts for soldering to a printed circuit board.
A number of connectors 1, formed in accordance with the above, are shown mounted to a substrate printed circuit board 20 in Figure 2. As can be seen, the base portion 2 is 20 secured relative to the circuit board 20 by inserting the lugs 12 to 14 through associated "i holes in the circuit board 20 and then soldering the lugs in place such that the connector 1 is rigidly connected to the board 20 for receipt of terminals 21 of an associated electric motor device 22. To effect electrical connection between one of the terminals 21 and the associated connector 1, the terminal is firstly positioned in the insertion space 10 and then forced down into the slot 7 so that the members 5 and 6 resiliently engage against the terminal. As such, a reliable electrical connection is established between the printed circuit board 20 and the terminal 21 via the connector 1. Positional variation between the motor 22 and the circuit board 20 such as caused by vibration of the motor 22 during operation or simply by slight misalignment of the location of the motor 22 on the board 20 due to manufacturing tolerances, may be readily accommodated by appropriate flexing of the linkage 4.
P.Z?~ERQDIft=O p&W1 cap dc-WI2J00 As may be appreciated then the connector of the invention provides a solution to the problems of the prior art insofar as the connector may be readily mounted to a printed circuit board and soldered in place to provide secure and reliable electrical connection with a motor terminal whilst absorbing stresses caused by operation of the motor, by virtue of the flexible linkage 4. Further the U-shaped configuration of the linkage and coupling portion 3 of the connector minimises the space for the connector on the PCB whilst still providing the function of flexibility. In addition, the connector may be made from sheet metal, with the relevant portions 2, 3 and lugs (12,13,14) bent into the appropriate positions by machine to allow the connector to be manufactured in bulk so as to minimise unit costs.
oooo As may also be appreciated some design variations may be made to the connector without departing from the spirit and scope of the invention. For example, the flexible linkage 4 15 may be formed as a double U-shape in order to increase flexibility and stress absorbing characteristics of the connector. The material of the connector may also be reduced in thickness and the insertion opening 11 may be widened, as required.
