Abstract

An electrical connector for interconnecting a first circuit board to a second circuit board that has a connector housing attachable to the first board, including a base plate in the vicinity of the first board with a plurality of openings for providing access to contact members on the first board; a floating terminal block cooperating with a plurality of individually resilient contacts that rely on normal forces to establish an electrical, flexible conductors extending between the base plate and the electrical contacts to establish an electrical connection between the first board and the second board; a biasing member positioned relative to the housing and the terminal block so that the terminal block, and the plurality of individually resilient contact elements are biased away from the housing, the biasing member exerting a spring force on the terminal block such that a mating force is established between the contacts and the second circuit board is established; and, a coupler for maintaining the relative positions connector to the mating circuit board.

Claims

1. An electrical connector for mating with a complementary component having a mating face and an anchor, the connector comprises

a connector housing having a connector coupler therein for engaging the anchor in a fixed manner and a terminal block for receiving individual contact modules, with resilient contacts, therein and arranged complementarily to the mating face, wherein the terminal block is floatably coupled to the connector housing and resiliently biased therefrom by a resilient member such that the coupling force at the mating face is determined by the force of the resilient member.

2. The connector of claim 1, wherein the connector housing and terminal block include a releasable latch therebetween such that the terminal block is held back from the mating face until the coupler engages the anchor.

3. The connector of claim 1, wherein the connector housing is floatably mounted on a substrate such that when the substrate and the complementary component are mated, the mating force at the complementary component is determined by the resilient member relatively independent of the position of the substrate relative the complementary component.

4. The connector of claim 2, wherein the connector housing and the terminal block must be latched together in order for the coupler to engage the anchor such that the mating occurs, thereby preventing pushback or stubbing.

5. The connector of claim 3, wherein the coupler is spring loaded.

6. The connector of claim 4, wherein the latch is re-engaged upon demating.

7. An electrical connector for mounting to a first board to establish an interconnection to a second board having a mating face thereupon, where an anchor is provided for positioning the electrical connector relative the second board, the electrical connector comprising:

a connector housing attachable to the first board, including a base plate to be positioned in the vicinity of the first board and including a plurality of openings for providing access to contact members on the first board;

a floating terminal block for carrying a plurality of individually resilient contacts that rely on normal forces established perpendicularly to the mating face to establish an electrical connection with the mating face of the second board, flexible conductors extending between the base plate and the terminal block to the establish the electrical connection between the first board and the second board; and

, a biasing member positioned relative the housing and the terminal block so that the terminal block is biased away from the housing, the biasing member exerting a spring force on the terminal block such that a mating force is established; and

a coupler for engaging the anchor in a fixed manner.

8. The electrical connector of claim 7, wherein the biasing member is a coil spring.

9. The electrical connector of claim 8, wherein the positioning of the electrical connector relative the mating face of the second board is determined by a pin-and-socket structure incorporated into the connector and the second board.

10. The electrical connector of claim 9, wherein the anchor and the coupler are also the pin-and-socket structure.

11. The electrical connector of claim 7, wherein when the anchor and the coupler are engaged, the biasing member causes a mating force to be exerted on the terminal block and through to the mating face of the second board, the mating force being relatively independent of the positioning of the electrical connector and the second board.

12. An electrical connector for interconnecting a first circuit board to a second circuit board where the connector is adapted to be mounted to the first circuit board and the second circuit board is provided with an anchor, the electrical connector comprising:

a connector housing attachable to the first board, including a base plate to be positioned in the vicinity of the first board and including a plurality of openings for providing access to contact members on the first board;

a floating terminal block cooperating with a plurality of individually resilient contacts that rely on normal forces established perpendicularly to the mating face to establish an electrical connection with the mating face of the second board, flexible conductors extending between the base plate and the electrical contacts to establish an electrical connection between the first board and the second board;

a biasing member positioned relative the housing and the terminal block so that the terminal block, and the plurality of individually resilient contact elements are biased away from the housing, the biasing member exerting a spring force on the terminal block such that a mating force is established between the contacts and the second circuit board is established; and

, a coupler for engaging the anchor in a fixed manner.
