Abstract

It is often a requirement for a module to have two connectors; one for inputs and one for outputs. Addi- tionally, it may be a requirement for high current signals to be passed directly through the module from input to output. If two separate connectors are used, as is the normal method, this high current must be transmitted through, the following: the input terminal, solder joint, a heavy PC61 trace, another solder joint, and the output terminal.

INTEGRATED INPUT/OUTPUT 90 DEGREE CONNECTOR

by Dan Berg, Jasmin Farshi, John Harmon, and Peter Skocik

   It is often a requirement for a module to have two connectors; one for inputs and one for outputs. Addi- tionally, it may be a requirement for high current signals to be passed directly through the module from input to output. If two separate connectors are used, as is the normal method, this high current must be transmitted through, the following: the input terminal, solder joint, a heavy PC61 trace, another solder joint, and the output terminal.

   The present method to accomplish this is to integrate both connectors into one, with the outputs at 90 degrees from the inputs. This connector has terminals carrying current in three directions: 1) input to PCB, 2) input to output, and 3) PCB to output. (see figure)

   By implementing the integrated 90 degree connector several improvements are achieved. Operating temperature of the module is lower because energy is kept away from the PCB and otherelectrical components. PCB density is lower because only two connector mounting bosses are needed instead of four and high current traces between connectors are eliminated. Manufacturing is simplified with fewer parts to qualify, purchase and stock, reduced assembly time, and fewer defects. Additionally, product cost is lowered since the cost of one more complex connector is less than two less complex connectors.
