(2) hypomere of metal pin forms and is electrically connected with the first plated through-hole welding; The epimere of metal pinForm and be electrically connected with the second plated through-hole welding.
Advantage of the present invention is: improved the shield effectiveness of upper and lower two-layer strip line, ensured metal pinWhat contact with plated through-hole in upper and lower two-layer strip line is good, has avoided originating port standing wave to increase, transmitThe problem that loss increase, switching performance decline.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below the present invention is described in further details. Referring to Fig. 1, a kind of strip line end connecting structure,Comprise termination of the first strip line 1 and a termination of the second strip line 2, the first strip line 1Termination is positioned at below the second strip line 2 terminations, and the first strip line 1 by micro-band plate above and belowThe overlapping composition of matching disc has one near connection end end on the plate face of first strip line 1 micro-band plateThe first plated through-hole of the micro-band plate of individual perforation, the micro-band transmission in the first plated through-hole and the first strip line 1Line forms electrical connection; The second strip line 2 is by micro-band plate below and overlapping composition of matching disc above,On the plate face of second strip line 2 micro-band plates, there is one to connect second of micro-band plate near connection end endPlated through-hole, the second plated through-hole forms and is electrically connected with the microstrip transmission line in the second strip line 2; Also bagDraw together a metal pin 3, its hypomere is positioned at the first plated through-hole, the lower surface of metal pin 3 and firstThe lower surface of micro-band plate of strip line 1 is coplanar, and the epimere of metal pin 3 is positioned at the second plated through-hole,The upper surface of the upper surface of metal pin 3 and second strip line 2 micro-band plates is coplanar; It is characterized in that,
(1) at first upper surface of strip line 1 micro-band plate and the end face of link and the first strip line 1The lower surface of matching disc and the end face of link are all pasted with metal forming, on the micro-band plate of the first strip line 1In the metal forming on surface, there is first circular hole coaxial with the first plated through-hole, the diameter of this first circular holeBe greater than the first plated through-hole, the metal forming of the first strip line 1 connecting end surface and the micro-band plate of the first strip line 1The metal forming of the metal forming of upper surface and matching disc lower surface keeps electrical connection; At the micro-band of the second strip line 2The upper surface of the lower surface of plate and the end face of link and the second strip line 2 matching discs and the end of linkFace is all pasted with metal forming, in the metal forming of the micro-band plate lower surface of the second strip line 2, has one and secondThe second circular hole that plated through-hole is coaxial, the diameter of this second circular hole is greater than the second plated through-hole, the second band shapeOn the metal forming of the metal forming of line 2 connecting end surfaces and the micro-band plate lower surface of the second strip line 2 and matching disc, showThe metal forming of face keeps electrical connection;
