Abstract
Collector clips arranged on a circuit breaker trip unit printed circuit board allow removable connection between the trip unit circuit and the circuit within a field-installable rating plug as well as other auxiliary electrical devices. The connector clips are oriented to the rating plug and the trip unit to prevent cold flow of the solder at the junction between the ends of the connector clips and the receiving holes formed within the trip unit circuit board.
Claims9
An electrical connector clip comprising:
- a metal stamping defining a pair of opposing edges joined by a pair of opposing sides;
- a hook-shaped configuration at one end of said stamping, said hook-shaped configuration arranged for receiving a first primed circuit board;
- a linear configuration at an opposite end of said stamping, said linear configuration arranged for insertion and solder connection within openings formed in a second printed circuit board;
- and
- a stop formed within said stamping intermediate said hook-shaped configuration and said linear configuration, said stop arranged for abutting against a top part of said openings.
The electrical connector clip of claim 3 wherein said width is at least twice said thickness.
A circuit breaker having variable ampere ratings comprising:
- a molded plastic case;
- a molded plastic cover attached to said case;
- a pair of separable contacts within said case arranged for interrupting a protected electrical circuit;
- a trip unit circuit board within said cover controlling open and closed conditions of said contacts, said trip unit circuit board including a plurality of connector clips, each of said clips comprising a metal stamping defining a pair of opposing edges joined by a pair of opposing sides;
- a hook-shaped configuration at one end of said stamping, said hook-shaped configuration arranged for receiving an auxiliary printed circuit board;
- a linear configuration at an opposite end of said stamping, said linear configuration arranged for insertion and solder connection within openings formed in said trip unit printed circuit board;
- and
- a stop formed within said stamping intermediate said hook-shaped configuration and said linear configuration, said stop arranged for abutting against a top part of said openings.
