Low inductance connector assembly
View Patent ↗A busbar connector assembly for coupling first and second terminals on a two-terminal device to first and second contacts on a power module is provided. The first terminal resides proximate the first contact and the second terminal resides proximate the second contact. The assembly comprises a first bridge having a first end configured to be electrically coupled to the first terminal, and a second end configured to be electrically coupled to the second contact, and a second bridge substantially overlapping the first bridge and having a first end electrically coupled to the first contact, and a second end electrically coupled to the second terminal.
1. A connector assembly comprising:
a first busbar and a second busbar on a busbar assembly, the first busbar having a first terminal and the second busbar having a second terminal;
a power module with a first contact and a second contact, wherein the first terminal resides proximate the first contact and the second terminal resides proximate the second contact;
a first bridge having a first end and a second end, the first bridge comprising:
a first connecting tab electrically contacted to the first terminal proximate the first end of the first bridge and overlapping with the first and second busbars;
a first end terminal electrically contacted to the second contact proximate the second end of the first bridge;
a first center section coupled between the first connecting tab and the first end terminal; and
a first fastener configured to clamp and electrically couple the first connecting tab and the first busbar together, and wherein the first connecting tab, the first center section, and the first end terminal are integrally formed; and
a second bridge having a first end and a second end, the second bridge comprising:
a second connecting tab electrically contacted to the second terminal proximate the second end of the second bridge and overlapping with the first and second busbars;
a second end terminal electrically contacted to the first contact proximate the first end of the second bridge; and
a second center section coupled between the second connecting tab and the second end terminal; and
a second fastener configured to clamp the second connecting tab and the first and second busbars together, and to electrically couple the second busbar to the second connecting tab, and wherein the second connecting tab, the second center section, and the second end terminal are integrally formed, and wherein the first and second center sections are configured to substantially overlap each other.
2. A busbar connector comprising:
a first busbar having a first terminal and a second busbar having a second terminal;
a power module with a first contact residing proximate to the first terminal and a second contact residing proximate to the second terminal;
a first bridge having a first end and a second end, the first bridge comprising:
a first connecting tab coupled to the first terminal proximate the first end of the first bridge and overlapping with the first and second busbars;
a first end terminal coupled to the second contact proximate the second end of the first bridge; and
a first center section coupled between the first connecting tab and the first end terminal; and
a second bridge having a first end and a second end, the second bridge comprising:
a second connecting tab coupled to the second terminal proximate the second end of the second bridge and overlapping with the first and second busbars;
a second end terminal coupled to the first contact proximate the first end of the second bridge;
a second center section coupled between the second connecting tab and the second end terminal, and wherein the first and second center sections are configured to substantially overlap each other;
a first fastener that clamps and electrically couples the first connecting tab and the first busbar together; and
a second fastener that clamps the second connecting tab and the first and second busbars together, the second fastener configured to electrically couple the second busbar and the second connecting tab.
3. An assembly according to claim 2 , wherein the first connecting tab, the first center section, and the first end terminal are integrally formed.
4. An assembly according to claim 2 , wherein the first center section has a first portion and a second portion, and the first portion is substantially orthogonal to the second portion and the first connecting tab.
5. An assembly according to claim 4 , wherein the second portion is substantially orthogonal to the first end terminal.
