Z-directed delay line components for printed circuit boards
First Claim
1. A Z-directed component signal delay line for mounting in a PCB having a mounting hole having a depth D therein, comprising:
- an insulative body having a top surface, a bottom surface and a side surface, a cross-sectional shape that is insertable into the mounting hole in the PCB and a length L defining a lengthwise direction;
a signal conductor contained within the body between the top and bottom surface forming a first electrical path of the Z-directed component for passing a signal therethrough and having a length that is greater than the length L comprising;
a plurality of C-shaped conductors spaced apart from one another; and
a plurality of leg segments disposed along the lengthwise direction of the body, the plurality of C-shaped conductors serially connected by the plurality of leg segments;
a pair of conductive traces, each conductive trace of the pair of conductive traces being provided on one of the surfaces of the body and connected to a respective end of the signal conductor; and
a shorting bar extending along the lengthwise direction of the body and contacting at least two of the plurality of C-shaped conductors forming a second electrical path of the Z-directed component electrically shorting together said at least two C-shaped conductors thereby electrically shorting the first electrical path,wherein adjacent C-shaped conductors are aligned opposite one another to provide current flow through adjacent C-shaped conductors in opposite directions such that current flows through a first of the C-shaped conductors in a clockwise direction and through a second of the C-shaped conductors adjacent the first C-shaped conductor in a counterclockwise direction.

Abstract
A Z-directed signal delay line component for insertion into a printed circuit board while allowing electrical connection to internal conductive planes contained with the PCB. In one embodiment the Z-directed delay line component is housed within the thickness of the PCB allowing other components to be mounted over it. The delay line embodiments include a W-like line and a plurality of spaced apart, semi-circular line segment connected such that current flow direction alternates in direction between adjacent semi-circular line segments, each of which in other embodiments can be varied by use of shorting bars. Several Z-directed delay line components may be mounted into a PCB and serially connected to provide for longer delays. The body may contain one or more conductors and may include one or more surface channels or wells extending along at least a portion of the length of the body. Methods for mounting Z-directed components are also provided.
