High speed, high signal integrity electrical connectors
View Patent ↗An electrical connector may include a connector housing and a terminal tray. The terminal tray may include a tray body having a latch extending therefrom. The connector housing may define a latch receiving window. The latch and latch receiving window may be disposed such that the latch engages the latch receiving window only when the terminal tray is received in the housing in a preferred orientation. The terminal tray may include an electrically conductive contact having a board receiving end adapted to receive a printed circuit board and to exert sufficient pressure on the printed circuit board to retain the printed circuit board between the contact and the tray body. The connector may also include a plurality of cables bundled by a band, such as double-sided tape, such that respective portions of the cables are restrained from movement relative to one another.
1. A terminal tray for an electrical connector, the terminal tray comprising:
a tray body made of an electrically insulating material; and
an electrically conductive contact, said contact having a connector mating end that extends beyond an end of the tray body and a board receiving end opposite the connector mating end,
wherein the board receiving end of the contact is adapted to receive a printed circuit board and to exert sufficient pressure on the printed circuit board to retain the printed circuit board between the contact and the tray body and wherein the terminal tray has a location key extending therefrom, said location key being adapted to align with a complementary slot in the printed circuit board.
2. The terminal tray of claim 1 , wherein the contact extends at least partially through the tray body.
3. The terminal tray of claim 1 , wherein the tray body is overmolded onto the contact.
4. The terminal tray of claim 1 , wherein the tray body includes a tray bar that prevents the contact from moving while the printed circuit board is being slid between the contact and the tray body.
5. The terminal tray of claim 1 , wherein the tray body includes a press-fit pin extending therefrom, said press-fit pin being adapted to extend through a complementary hole in the printed circuit board.
6. The terminal tray of claim 1 , wherein the tray body includes a latch extending therefrom, said latch being adapted to engage a complementary window in a connector header that is adapted to receive said terminal tray in an interior thereof.
7. The terminal tray of claim 1 , wherein the terminal tray has a rib extending therefrom, said rib being adapted to stop the printed circuit board from moving in a direction in which the circuit board may be slid between the contact and the tray body.
8. The terminal tray of claim 1 , wherein the contact is resilient and is adapted to exert a spring force on the printed circuit board.
9. The terminal tray of claim 1 , wherein the board receiving end of the contact is generally curved.
10. An electrical connector, comprising:
a connector header having a housing that defines an interior thereof, said housing further defining a plurality of latch receiving windows; and
first and second terminal trays received within the interior of the connector header, each of the first and second terminal trays comprising a tray body made of an electrically insulating material and having a latch extending therefrom, and an electrically conductive contact having a connector mating end that extends beyond an end of the tray body;
wherein each latch receiving window is disposed such that the first terminal tray is received in the connector header in a first orientation and the second terminal tray is received in the connector header adjacent to the first terminal tray only in a second orientation, the first and second orientations being different.
11. The electrical connector of claim 10 , wherein the latch extends from a face of the tray body, the face having a first end and a second end, the latch disposed off-center between the ends of the face.
12. The electrical connector of claim 10 , wherein each latch receiving window is disposed to receive a latch of a tray body only after the second terminal tray is rotated 180° with respect to the first terminal tray.
13. The electrical connector of claim 10 , wherein the shape of the terminal tray body of the first terminal tray is the same as the shape of the terminal tray body of the second terminal tray.
14. The electrical connector of claim 10 , wherein said housing includes a tray receiving groove that extends from each latch receiving window of the plurality of latch receiving windows along an interior wall of the housing.
15. A terminal tray for an electrical connector, the terminal tray comprising:
a tray body made of an electrically insulating material; and
an electrically conductive contact, said contact having a connector mating end that extends beyond an end of the tray body and a board receiving end opposite the connector mating end,
wherein the board receiving end of the contact is adapted to receive a printed circuit board and to exert sufficient pressure on the printed circuit board to retain the printed circuit board between the contact and the tray body and wherein the terminal tray has a rib extending therefrom, said rib being adapted to stop the printed circuit board from moving in a direction in which the circuit board may be slid between the contact and the tray body.
16. The terminal tray of claim 15 , wherein the contact extends at least partially through the tray body.
17. The terminal tray of claim 15 , wherein the tray body is overmolded onto the contact.
18. The terminal tray of claim 15 , wherein the tray body includes a tray bar that prevents the contact from moving while the printed circuit board is being slid between the contact and the tray body.
19. The terminal tray of claim 15 , wherein the tray body includes a press-fit pin extending therefrom, said press-fit pin being adapted to extend through a complementary hole in the printed circuit board.
20. The terminal tray of claim 15 , wherein the tray body includes a latch extending therefrom, said latch being adapted to engage a complementary window in a connector header that is adapted to receive said terminal tray in an interior thereof.
21. The terminal tray of claim 15 , wherein the contact is resilient and is adapted to exert a spring force on the printed circuit board.
22. The terminal tray of claim 15 , wherein the board receiving end of the contact is generally curved.
