Abstract

Modular connectors employ terminal carriers for gang mounting of terminals onto circuit substrates. The carriers may be shielded for providing shielding through the connector. Substrate mounting systems include press fit, floating surface mount, solder ball and intrusive reflow arrangements.

Claims

1. An electrical connector having a mating interface and a mounting interface comprising:

(a) at least one circuit substrate having a body and a plurality of conductive circuit traces carried by the body, the traces extending from a first region of the body adjacent the mating interface to a second region of the body adjacent the mounting interface;

(b) a plurality of electrical terminals, each associated with one of the traces;

(c) a housing, formed of electrically insulative material, mounted on the body in at least one of the first and second regions, carrying the terminals, and having a shield member for electrically shielding the terminals, the shield member including portions positioned in shielding relationship with respect to at least one of the terminals; and

(d) a support maintaining the at least one circuit substrate in a substantially parallel assembled state.

2. An electrical connector as in claim 1, wherein the terminals include surface mount portions for mounting the terminals on the traces.

3. An electrical connector as in claim 1, wherein the shield member secures to the housing onto the circuit substrate by surface mounting techniques.

4. An electrical connector as in claim 1, wherein the terminal has a press fit section and the housing includes a force transmitting portion for receiving an insertion force for pressing the terminal into the circuit substrate and transmitting the insertion force to the terminal.

5. An electrical connector as in claim 1, wherein said plurality of terminals have a deformable element disposed along said mounting interface to establish electrical contact with a circuit element on which the connector is mounted.

6. An electrical connector as in claim 5, wherein the deformable element is heat deformable.

7. An electrical connector as in claim 6, wherein the deformable element is a solder ball.

8. An electrical connector as in claim 1, wherein the housing includes structure for receiving the body and the body is secured to the structure by an interference fit.

9. An electrical connector as in claim 1, wherein an open zone is present on one side of the circuit substrate for receiving electronic elements mounted on the circuit substrate.

10. An electrical connector as in claim 1, wherein the shield member includes at least one tab engaging the support.

11. An electrical connector as in claim 10, further comprising a spring element removably secured to the support and engaged by the tab of the shield member.

12. An electrical connector as in claim 1, wherein the support includes a wall separating adjacent substrates.

13. A method of making an electrical connector comprising:
