Abstract

There exists a problem disconnecting a four-contact flat wire bus from a pluggable power connector housing. Removal of a bus would be required if a flat wire bus assembly is mis-plugged into the housing or, in the field, an engineering change must be made which requires a new assembly or re-routing of an existing assembly. The contacts of a flat wire bus assembly have a shoulder which, when pushed into the housing, slides past four plastic molded clips. These clips hold the contact in after the shoulder has been pushed past the clips and all the way to the bottom of the power connector socket. The configuration of the clips and shouldered contacts is shown in Fig. 1 which shows two contacts bonded to a flat wire bus and inserted into a power connector housing.

Flexible Distribution System Extraction Tool

There exists a problem disconnecting a four-contact flat wire bus from a pluggable power connector housing. Removal of a bus would be required if a flat wire bus assembly is mis-plugged into the housing or, in the field, an engineering change must be made which requires a new assembly or re-routing of an existing assembly. The contacts of a flat wire bus assembly have a shoulder which, when pushed into the housing, slides past four plastic molded clips. These clips hold the contact in after the shoulder has been pushed past the clips and all the way to the bottom of the power connector socket. The configuration of the clips and shouldered contacts is shown in Fig. 1 which shows two contacts bonded to a flat wire bus and inserted into a power connector housing.

An extraction tool is provided which will remove the flat wire bus contact assembly without damaging the precious metal plating of the contacts or damage the housing. This tool has a group of eight partially hollow cylinders which have an outside diameter approximately the same size as the shoulder on the contact. The inside diameter is slightly larger than the diameter of the contact above the shoulder which allows the tool to pass over the contact without damaging it. The eight cylinders are held together in a rectangular block, as shown in Fig. 2. The tool has two slots of specific width cut through the center of the two rows of cylinders. These slots allow th...
