Plug connector having a tab terminal for a power connector system
A plug connector includes a housing having a mating end and a cable end. The mating end is configured to be mated with a header connector in a mating direction. A tab terminal is held in the housing at the mating end. The tab terminal has a leading edge configured to be mated with the header terminal of the header connector when the plug connector is mated to the header connector. The leading edge is tapered such that the tab terminal sequentially mates with the header terminal during mating.
1. A plug connector comprising:
a housing having a mating end and a cable end, the mating end being configured to be mated with a header connector in a mating direction; and
a tab terminal held in the housing at the mating end, the tab terminal having a leading edge configured to be mated with a header terminal having opposing rows of plural points of contact of the header connector when the plug connector is mated to the header connector, the leading edge being tapered such that the tab terminal sequentially mates with the opposing rows of plural points of contacts of the header terminal along the leading edge during mating.
2. The plug connector of claim 1 , wherein the leading edge is angled non-orthogonal relative to the mating direction.
3. The plug connector of claim 1 , wherein the leading edge is angled relative to mating interfaces of the header terminal.
4. The plug connector of claim 1 , wherein the tab terminal extends along a longitudinal axis to a tip, the leading edge being angled non-parallel to the longitudinal axis.
5. The plug connector of claim 1 , wherein the tab terminal has a plurality of mating interfaces along the leading edge, adjacent mating interfaces of the tab terminal mating with corresponding mating interfaces of the header terminal at different times.
6. The plug connector of claim 1 , wherein the sequential mating with the header terminal reduces the tab terminal engagement force with the header terminal.
7. The plug connector of claim 1 , wherein the header terminal includes multiple contact members arranged in a stacked arrangement, the leading edge of the tab terminal engaging different contact members of the header terminal sequentially during mating.
8. The plug connector of claim 1 , wherein the tab terminal has first and second sides that are both configured to engage the header terminal.
9. The plug connector of claim 1 , wherein the tab terminal includes a trailing edge opposite the leading edge, the trailing edge having the same shape as the leading edge.
10. The plug connector of claim 1 , wherein the leading edge is inwardly tapered.
11. The plug connector of claim 1 , wherein the leading edge includes a first angled portion and a second angled portion at different angles.
12. A power connector system comprising:
a header connector having a header housing holding a plurality of contact members, each contact member having a fork contact at a mating end thereof, each fork contact having a pair of spring beams defining a socket, the contact members being arranged side-by-side in a stacked arrangement to define a header terminal such that the sockets of the contact members are aligned to define a tab socket of the header terminal, the stacked arrangement of contact members having the contact members arranged in opposing rows of points of contact; and
a plug connector having a plug housing holding a tab terminal, the plug housing having a mating end and a cable end with a power cable extending from the cable end, the mating end being mated with the header connector in a mating direction during mating, the tab terminal having first and second sides, the tab terminal having a cable end terminated to the power cable, the tab terminal having a leading edge received within the tab socket of the header terminal and engaging the fork contacts of the contact members of the header terminal when the plug connector is mated to the header connector, the leading edge being tapered such that the tab terminal sequentially mates with the opposing rows of points of contacts defined by the contact members of the header terminal along the leading edge during mating.
13. The power connector system of claim 12 , wherein the leading edge of the tab terminal is angled non-orthogonal relative to the mating direction.
14. The power connector system of claim 12 , wherein the leading edge of the tab terminal is angled relative to mating interfaces on the spring beams of the contact members.
15. The power connector system of claim 12 , wherein the spring beams each have a mating interface, the mating interfaces of the spring beams being aligned along a spring beam plane, the leading edge of the tab terminal being angled relative to the spring beam plane.
16. The power connector system of claim 12 , wherein the tab terminal extends along a longitudinal axis to a tip, the leading edge being angled non-parallel to the longitudinal axis.
17. The power connector system of claim 12 , wherein the tab terminal has a plurality of tab mating interfaces along the leading edge, the spring beams having spring beam mating interfaces, wherein adjacent tab mating interfaces mate with corresponding spring beam mating interfaces at different times during mating.
18. The power connector system of claim 12 , wherein the first and second sides of the tab terminal are configured to engage the header terminals.
19. The power connector system of claim 12 , wherein the leading edge of the tab terminal is inwardly tapered.
