Decoupled alignment shroud for variable connector routing
A shroud configured to connect a leadframe to a battery system for a hybrid motor vehicle is provided. The shroud is removably attachable to the leadframe. The shroud has at least one shroud alignment feature, the shroud being removably attached to the leadframe in a predetermined orientation wherein the shroud alignment feature is aligned with a complimentary leadframe alignment feature. The shroud may include a hollow cylindrical portion and at least one connecting feature configured to attach the shroud to the leadframe. The shroud may be provided as part of a connector system that includes the leadframe. In this case, the leadframe is configured to provide an electrical and mechanical connection between a power inverter and the battery system of the electric motor. The leadframe includes at least one leadframe alignment feature that is aligned with the shroud alignment feature.
1. A connector system for a hybrid motor vehicle, the connector system comprising:
a leadframe configured to provide an electrical and mechanical connection between a power inverter and a battery system of an electric motor, the leadframe having at least one leadframe alignment feature;
a shroud configured to connect the leadframe to the battery system, the shroud being removably attached to the leadframe, the shroud having at least one shroud alignment feature, the shroud being removably attached to the leadframe in a predetermined orientation wherein the at least one shroud alignment feature is aligned with the at least one leadframe alignment feature, the shroud comprises:
at least one connecting feature attaching the shroud to the leadframe, and
a wall shaped as a hollow cylinder, the wall defining an opening along a height of the wall,
a bolt extending from the leadframe;
a power inverter electrically and mechanically connected to the leadframe,
a battery system connector attached to the shroud,
wherein the shroud defines a hollow interior within the wall and the bolt extends into the hollow interior, the at least one shroud alignment feature comprises a first shroud alignment feature disposed along a first line and a second shroud alignment feature disposed along a second line, the first and second lines having an angle of about 120 degrees therebetween as measured from a center of the shroud.
2. The connector system of claim 1 , wherein:
the at least one leadframe alignment feature includes two leadframe slots,
the at least one shroud alignment feature includes a two shroud slots, and
each leadframe slot of the two leadframe slots is aligned with a shroud slot of the two shroud slots.
3. The connector system of claim 1 , wherein the at least one leadframe alignment feature comprises a first leadframe alignment feature and a second leadframe alignment feature, the battery system connector having a first battery connector alignment feature aligned with the first shroud alignment feature and the first leadframe alignment feature, the battery system connector having a second battery connector alignment feature aligned with the second shroud alignment feature and the second leadframe alignment feature, the first leadframe alignment feature and the first battery connector alignment feature being disposed along the first line, and the second leadframe alignment feature and the second battery connector alignment feature being disposed along the second line.
4. The connector system of claim 3 , wherein the shroud is press fit to the leadframe.
5. The connector system of claim 3 , wherein the shroud is clipped to the leadframe.
6. The connector system of claim 5 , wherein the wall defines a base portion disposed in a base portion plane, the at least one connecting feature comprising a plurality of connecting features extending from the base portion and beyond the base portion plane, the plurality of connecting features clipping the shroud to the leadframe.
7. A connector system for a hybrid motor vehicle, the connector system comprising:
a leadframe configured to provide an electrical and mechanical connection between a power inverter and a battery system of an electric motor, the leadframe having at least one leadframe alignment feature; and
a shroud configured to connect the leadframe to the battery system, the shroud being removably attached to the leadframe, the shroud having at least one shroud alignment feature, the shroud being removably attached to the leadframe in a predetermined orientation wherein the at least one shroud alignment feature is aligned with the at least one leadframe alignment feature;
wherein the at least one shroud alignment feature comprises a first shroud alignment feature disposed along a first line and a second shroud alignment feature disposed along a second line, the first and second lines having an angle of about 120 degrees therebetween as measured from a center of the shroud.
