Abstract

A multiport zero insertion force (ZIF) connector can include a multiport connector housing defining an opening and an interior space for receiving a multi-path circuit device having multiple types of electrical connection paths therethrough and multiple LIGA springs positioned within the interior space to apply pressure to the multi-path circuit device while in a first position. A locking component can be configured to cause the LIGA springs to move to a second position responsive to a user pressing the locking component, wherein the LIGA springs do not apply pressure to the multi-path circuit device while in the second position.

Claims

1. A multiport zero insertion force (ZIF) connector for test and measurement devices, comprising:

a multiport connector housing defining an opening and an interior space suitable for receiving a multi-path circuit device having multiple types of electrical connection paths therethrough;

a plurality of LIGA springs positioned within the interior space and configured to apply pressure to the multi-path circuit device while in a first position, wherein each of the plurality of LIGA springs facilitates an electrical connection between one of a plurality of connection points on the multi-path circuit device and a test/measurement instrument; and

a locking component configured to cause the plurality of LIGA springs to move to a second position responsive to a user pressing the locking component, wherein the plurality of LIGA springs do not apply pressure to the multi-path circuit device while in the second position.

2. The multiport ZIF connector of claim 1, wherein the locking component is further configured to cause the plurality of LIGA springs to move back to the first position responsive to the user releasing the locking component.

3. The multiport ZIF connector of claim 1, wherein the plurality of LIGA springs remain in the second position so long as the user continues to press the locking member.

4. The multiport ZIF connector of claim 1, wherein the opening is a slotted opening.

5. The multiport ZIF connector of claim 4, wherein the circuit device is a flex circuit.

6. The multiport ZIF connector of claim 1, wherein each of the plurality of LIGA springs has a generally helical shape or a cantilever shape.

7. The multiport ZIF connector of claim 1, wherein the plurality of LIGA springs are generated by way of an x-ray fabrication technique.

8. The multiport ZIF connector of claim 1, wherein the plurality of LIGA springs are generated by way of an ultraviolet (UV) light fabrication technique.

9. The multiport ZIF connector of claim 1, further comprising a rear portion configured to receive a connecting member.

10. The multiport ZIF connector of claim 9, wherein the connecting member includes at least one coaxial line, at least one direct current (DC) line, or both at least one coaxial line and at least one DC line.

11. The multiport ZIF connector of claim 10, wherein the connecting member includes two or more connecting members and further wherein a protective encasing encases the two or more connecting members.

12. The multiport ZIF connector of claim 9, wherein the rear portion defines at least one side hole configured to be used as an attachment point for an accessory.

13. The multiport ZIF connector of claim 9, further comprising a plurality of support ribs integrated with the rear portion, wherein the plurality of ribs is configured to be used as an attachment point for an accessory.

14. The multiport ZIF connector of claim 1, further comprising a plurality of positioning portions within the interior space, wherein the plurality of positioning portions are configured to align the multi-path circuit device within the interior space.

15. The multiport ZIF connector of claim 1, wherein the test/measurement instrument is an oscilloscope.

16. A multiport interconnect system, comprising:

a device under test (DUT);

a multi-path circuit device that is physically and electrically coupled with the DUT; and

a zero insertion force (ZIF) connector electrically coupled with the DUT, the ZIF connector including;

a connector housing defining an opening and an interior space suitable for receiving the mating member;

a plurality of LIGA springs positioned within the interior space and configured to apply pressure to the mating member while in a first position, wherein each of the plurality of LIGA springs facilitates an electrical connection between one of a plurality of connection points on the multi-path circuit device and a test/measurement instrument; and

a locking component configured to cause the plurality of LIGA springs to move to a second position responsive to a user pressing the locking component, wherein the plurality of LIGA springs do not apply pressure to the mating member while in the second position.

17. The multiport interconnect system of claim 16, wherein the test instrument is an oscilloscope.

18. The multiport interconnect system of claim 16, wherein the mating member is a flex circuit.

19. The multiport interconnect system of claim 16, further comprising a plurality of connecting members electrically coupled between the ZIF connector and the test instrument.

20. The multiport interconnect system of claim 16, wherein the test/measurement instrument is an oscilloscope.
