Abstract

This article discloses a universal power connection which includes a power cord and a universal product connector (UPC). The power cord is customized at the time of construction such that it does the proper voltage selection for a product. The UPC becomes a multi-pin connector with enough contacts to allow handling a total product line. Many products today use a removable power cord with a universal product connector at one end and a standard 110 VAC or 220 VAC plug on the other end depending upon the application. This allows the manufacturer to build its products with one common power interface while using different power cords for products which employ different voltages. The UPC normally employs two (hot and neutral) or three (hot, neutral and ground) connections.

Universal Power Connection

This article discloses a universal power connection which includes a power cord and a universal product connector (UPC). The power cord is customized at the time of construction such that it does the proper voltage selection for a product. The UPC becomes a multi-pin connector with enough contacts to allow handling a total product line. Many products today use a removable power cord with a universal product connector at one end and a standard 110 VAC or 220 VAC plug on the other end depending upon the application. This allows the manufacturer to build its products with one common power interface while using different power cords for products which employ different voltages. The UPC normally employs two (hot and neutral) or three (hot, neutral and ground) connections. Within the product a jumper board or equivalent is used to select the proper voltage. This is normally the inputs to a multitap transformer for proper device operation. This requires the proper connection of the transformer and the UPC, plus any jumpers, to the jumper board. This is usually done by manual means. These operations allow for the possibility of human error in wiring on the jumper board, such as the wrong power cord being selected, allowing an incorrect voltage source to be connected to the product device. This can lead to fires, explosions, power interruptions, product damage, etc. In the concept described herein, these problems are solved by moving the require...
