Abstract

The present invention provides a motor boot for mechanically and electrically connecting a motor to a circuit board and includes a vibrational damping housing constructed of elastomeric material. The housing has a slot formed therein and a receptacle for slidably receiving and releasably securing the motor therein by interference fit. The receptacle includes a cut-out in fluid flow communication with the slot for receiving the electrical pad of the motor. A vibrational damping connector disposed in the slot and contacts the pad of the motor thereby creating electrical communication between the motor and circuit board. The connector is constructed of an electrically conductive elastomeric material, absorbs mechanical energy of the motor, transfers electrical energy of the motor to the circuit board. The connector is integrally formed with the housing thereby making the motor boot of one piece construction or is slidably received and releasably secured within the slot by interference fit.

Claims

1. A motor boot for mechanically and electrically connecting a motor to a circuit board having an electrical contact and the motor having an electrical pad and a nob, disposed thereon, the motor boot comprising:

a elongated vibrational damping housing constructed of elastomeric material, U-shaped, and including a first support leg with a slot disposed therein, a second support leg spaced apart from the first support leg, and a base integrally formed with the first and second support legs;

a substantially enclosed cylindrical receptacle formed in the housing for slidably receiving and releasably securing the motor therein by interference fit, the receptacle including a cut-out in fluid flow communication with the slot for receiving the electrical pad of the motor therein, and a port for receiving the nob of the motor therein;

a vibrational damping connector releasably disposed in the slot and contacting the electrical pad of the motor and the contact when the motor boot is connected to the circuit board, thereby creating electrical communication between the motor and circuit board, the connector being constructed of an electrically conductive elastomeric material; and

wherein the motor boot is connected to the circuit board by compression force being applied to the housing such that the connector abuts the contact.

2. The motor boot of claim 1 wherein the connector is integrally formed with the housing thereby making the motor boot of one piece construction.

3. The motor boot of claim 1 wherein the connector is slidably received and releasably secured within the slot by interference fit.

4. A motor boot for mechanically and electrically connecting a motor to a circuit board having an electrical contact and said motor having an electrical pad disposed thereon, said motor boot comprising:

an elongated substantially enclosed housing having an open ended receptacle for insertably and releasably receiving said motor therein;

said housing further including a slot having a first connector insertion end and a second end in communication with said receptacle, said received motor having said electrical pad placed adjacent to said second end of said slot;

a connector insertably accommodated within said first end of said slot so as to place said connector into electrical engagement with said electrical pad of said received motor at said second end of said slot and to permit compressive connection to said circuit board at said first end of said slot.

5. The motor boot of claim 4 wherein the connector is constructed of an electrically conductive elastomeric material.

6. The motor boot of claim 4 wherein both the housing and connector are constructed of an elastomeric material for damping vibration of the motor.

7. The motor boot of claim 4 wherein the connector is disposed in the housing via use of an adhesive.

8. The motor boot of claim 4 wherein the motor boot is connected to the circuit board by compression force being applied to the housing such that the connector abuts the contact.

9. The motor boot of claim 4 wherein the connector is integrally formed with the housing thereby making the motor boot of one piece construction.

10. The motor boot of claim 9 wherein the connector is constructed of an electrically conductive elastomeric material.

11. A motor boot for mechanically and electrically connecting a motor to a circuit board having an electrical contact and said motor having an electrical pad disposed thereon, said motor boot comprising:

an elongated substantially enclosed vibrational damping housing having an open ended receptacle for insertably and releasably receiving said motor therein;

said housing further including a slot having a first connector insertion end and a second end in communication with said receptacle, said received motor having said electrical pad placed adjacent to said second end of said slot;

a connector insertably accommodated within said first end of said slot so as to place said connector into electrical engagement with said electrical pad of said received motor at said second end of said slot, and to permit compressive connection to said circuit board at said first end of said slot, said connector insert being constructed of an electrically conductive elastomeric material.

12. The motor boot of claim 11 wherein both the housing and connector are constructed of an elastomeric material for damping vibration of the motor.

13. The motor boot of claim 11 wherein the connector is integrally formed with the housing thereby making the motor boot of one piece construction.

14. The motor boot of claim 11 wherein the connector is disposed in the housing via use of an adhesive.

15. The motor boot of claim 11 wherein the motor boot is connected to the circuit board by compression force being applied to the housing such that the connector abuts the contact.
