Abstract

A multi-connector set for signal testing having a rectangular base seat installed with a fixed testing connector and two adjustable testing connectors provided at the two lateral sides of the fixed testing connector for adjusting spaces of them from the fixed testing connector. The fixed and the adjustable testing connectors each has an SMA female connector, the base seat has on its bottom a cylindrical shank that has a bottom protecting cylinder to be moved up and down by protruding and retracting or be rotated or tilted, and each fixed and each adjustable testing connector has at its bottom a probe which further has a secondary female probe moving up and down by protruding and retracting; the secondary female probe has a bottom recess to be slipped over a probe at the center of an I-PEX connector. Thereby, multiple microwave electric circuits can be tested at one time to save time; and insertion holes on the bottoms of the fixed and the adjustable testing connector can be correctly slipped over the central probe of the I-PEX connector every time, this can increase the correctness of tested results.

Claims

1. A multi-connector set for signal testing, said multi-connector set is connected with a plurality of I-PEX connectors on an electric circuit board to take high-frequency signal for an analyzer to measure and analyze, and comprises:

a base seat being a rectangular member;

a fixed testing connector provided on said base seat, and having an SMA female connector connecting with an SMA male connector on a tailing end of a coaxial electric cable, and an end of a probe of said SMA female connector is connected with a probe provided at a center of an I-PEX connector, and

at least an adjustable testing connector provided on said base seat, and space of said adjustable testing connector from said fixed testing connector is adapted for adjusting, said adjustable testing connector has an SMA female connector connecting with said SMA male connector on said tailing end of said coaxial electric cable, and said end of said probe of said SMA female connector is connected with said probe provided at said center of said I-PEX connector.

2. The multi-connector set for signal testing as claimed in claim 1, wherein said base seat has at least an elongate hole for receiving said at least an adjustable testing connector;

and position of said adjustable testing connector in said elongate hole is adapted to adjusting its position and space from said fixed testing connector.

3. The multi-connector set for signal testing as claimed in claim 2, wherein said at least an adjustable testing connector has a cylindrical shank of which an upper end is formed an SMA female connector, and of which a flange is formed at its middle, diameter of said flange is larger than width of said elongate hole;

said cylindrical shank is extended from a bottom of said base seat through said elongate hole to make said SMA female connector protrude out of a top of said base seat, and a screw as well as a set of gaskets each with a diameter larger than a width of said elongate hole are screw connected with an outer screw thread of said SMA female connector, thus said SMA female connector and said flange are together fixedly clamped on said base seat.

4. The multi-connector set for signal testing as claimed in claim 3, wherein said probe of said at least an adjustable testing connector is formed on its upper end an insertion hole, and is formed on its lower end an inner hole;

said inner hole has therein a first spring which contacts a lower enlarged portion above a secondary female probe that is adapted for moving up and down by protruding and retracting;

said secondary female probe is formed on its bottom a recess to slip over said probe provided at said center of said I-PEX connector;

a middle insulating seat is provided in a middle section of said cylindrical shank to afford extending through of said probe of said adjustable testing connector; and

said middle insulating seat is provided therebeneath with a second spring which contacts an upper edge of a lower protecting cylinder;

said protecting cylinder is provided in its upper interior with a lower insulating seat to afford extending through of said probe of said secondary female probe;

said upper outer edge of said protecting cylinder is formed a flange, a diameter of said flange is larger than a diameter of an opening of on a bottom of said cylindrical shank;

said protecting cylinder envelops said recess of said secondary female probe, and presses said second spring to move up and down by protruding and retracting on said bottom of said cylindrical shank or to rotate or tilt.

5. The multi-connector set for signal testing as claimed in claim 4, wherein said cylindrical shank of said at least an adjustable testing connector is composed of an upper cylinder and a lower cylinder slipped in said upper cylinder and a middle insulating seat is provided at a slip-connecting position of said upper cylinder and said lower cylinder.

6. The multi-connector set for signal testing as claimed in claim 4, wherein said middle insulating seat in said at least an adjustable testing connector and said second spring have therebetween an O shaped ring.

7. The multi-connector set for signal testing as claimed in claim 4, wherein amount of said at least an adjustable testing connector is two, and said two adjustable testing connectors are respectively provided at two lateral sides of said fixed testing connector.

8. The multi-connector set for signal testing as claimed in claim 1, wherein said SMA female connector of said fixed testing connector is provided at a center in a front face of said base seat, and a probe of said fixed testing connector is bent for an angle of 90 degrees in said base seat;

said probe is formed on its lower end an inner hole which is provided therein with a first spring that contacts a lower enlarged portion above a secondary female probe adapted for moving up and down by protruding and retracting in said inner hole; and

said secondary female probe is formed on its bottom a recess to slip over a probe provided at said center of said I-PEX connector on said electric circuit board; and

more, said cylindrical shank of said fixed testing connector extends downwards within and from a bottom of said base seat;

said cylindrical shank has in its middle section a middle insulating seat to afford extending through of said probe of said fixed testing connector; and

said middle insulating seat is provided therebeneath with a second spring which contacts an upper edge of a lower protecting cylinder;

said protecting cylinder is provided in its upper interior with a lower insulating seat to afford extending through of said probe of said secondary female probe, an upper outer edge of said protecting cylinder is formed a flange, a diameter of said flange is larger than a diameter of a bottom opening of said cylindrical shank;

said protecting cylinder envelops said recess of said secondary female probe, and presses said second spring to move up and down by protruding and retracting on a bottom of said cylindrical shank or to rotate or tilt.

9. The multi-connector set for signal testing as claimed in claim 8, wherein said cylindrical shank of said fixed testing connector is composed of an upper cylinder and a lower cylinder slipped in said upper cylinder, a top of said upper cylinder is extended into said base seat to tightly fit therein, said lower cylinder is slipped in said upper cylinder from below, and said middle insulating seat is provided at a slip-connecting position of said upper and said lower cylinders.

10. The multi-connector set for signal testing as claimed in claim 8, wherein said middle insulating seat in said cylindrical shank of said fixed testing connector and said second spring have therebetween an O shaped ring.
