Abstract

An ultrasound transducer connector assembly including a low insertion force connector, a leaf spring latch and several alternative housing configurations.

Claims

1. An ultrasound transducer connector assembly comprising:

an electric circuit assembly;

an electrical connector for mating with a corresponding connector external to said ultrasound transducer connector assembly, coupled to said electric circuit assembly, and having a plurality of electrical contacts and an electrical connector housing disposed about said plurality of electrical contacts,

wherein said electrical connector and said corresponding connector cooperate to function as a low insertion force connector, said low insertion force connector comprising means for deflecting a conductive beam of one of said connectors, upon said mating, to contact an abutment of an exposed contact of the other of said connectors and thereby increase a wiping force between said conductive beam and said opposed contact;

a premolding disposed about said electric circuit assembly;

RFI shielding means disposed about said premolding, and coupled to said electrical connector housing; and

an overmolding disposed about said RFI shielding means.

2. The ultrasound transducer connector assembly of claim 1, wherein said premolding is composed of a plastic selected from the group consisting of polyethylene, thermoplastic, thermosetting and epoxy.

3. The ultrasound transducer connector assembly of claim 1, wherein said RFI shielding means is composed of a material selected from the group consisting of metal tape, metal wire mesh, and sheetmetal.

4. The ultrasound transducer connector assembly of claim 1, wherein said overmolding is composed of a plastic.

5. The ultrasound transducer connector assembly of claim 1, further comprising a latching means for mechanically securing said electrical connector to said corresponding connector.

6. The ultrasound transducer connector assembly of claim 5, wherein said latching means is a leaf spring latch.

7. An ultrasound transducer connector assembly comprising:

an electric circuit assembly that interface with an ultrasound transducer;

an electrical connector for mating with a corresponding connector external to said ultrasound transducer connector assembly, coupled to said electric circuit assembly, and having a plurality of electrical contacts and an electrical connector housing disposed about said plurality of electrical contacts,

wherein said electrical connector and said corresponding connector cooperate to function as a low insertion force connector, said low insertion force connector comprising means for deflecting a conductive beam of one of said connectors, upon said mating, to contact an abutment of an exposed contact of the other of said connectors and thereby increase a wiping force between said conductive beam and said opposed contact;

an electrically conductive shell disposed about said electric circuit assembly, and coupled to said electrical connector housing;

an overmolding disposed about said shell; and

a latching means for mechanically securing said electrical connector to said corresponding connector.

8. The ultrasound transducer connector assembly of claim 7, wherein said shell is composed of a metal.

9. The ultrasound transducer connector assembly of claim 7, wherein said shell is composed of a metalized plastic comprising a plastic selected from the group consisting of thermoplastic and thermosetting, and a metal film disposed about said plastic.

10. The ultrasound transducer connector assembly of claim 7, wherein said overmolding is composed of a plastic.

11. The ultrasound transducer connector assembly of claim 7, wherein said latching means is a leaf spring latch.

12. An ultrasound transducer connector assembly comprising:

an electric circuit assembly;

an electrical connector for mating with a corresponding connector external to said ultrasound transducer connector assembly, coupled to said electric circuit assembly, and having a plurality of electrical contacts and an electrical connector housing disposed about said plurality of electrical contacts,

wherein said electrical connector and said corresponding connector cooperate to function as a low insertion force connector, said low insertion force connector comprising means for deflecting a conductive beam of one of said connectors, upon a mating action, to contact an abutment of an exposed contact of the other of said connectors and thereby increase a wiping force between said conductive beam and said opposed contact;

an inner shell disposed about said electric circuit assembly;

a conductive wrap disposed about said inner shell, and coupled to said electrical connector housing;

an outer shell disposed about said conductive wrap.

13. The ultrasound transducer connector assembly of claim 12, wherein said inner shell is composed of a plastic selected from the group consisting of thermoplastic and thermosetting.

14. The ultrasound transducer connector assembly of claim 12, wherein said conductive wrap is selected from the group consisting of copper foil and wire mesh.

15. The ultrasound transducer connector assembly of claim 12, wherein said outer shell is composed of a plastic.

16. The ultrasound transducer connector assembly of claim 12, further comprising a latching means for mechanically securing said electrical connector to said corresponding connector.

17. The ultrasound transducer connector assembly of claim 16, wherein said latching means is a leaf spring latch.
