Abstract

An electrical connector includes an electrically insulative body and a conductive shield. The electrically insulative body has a plurality of terminals. Each terminal has a tail respectively clamped on a circuit board. The electrically insulative body has two backwardly extended locating blocks at two sides. Each locating block has a locating groove which receives the circuit board upon connection of the terminals to the respective contacts of the circuit board. The locating blocks also include flexible arms with upright portions adapted for engaging into respective retaining apertures on the circuit board. The conductive shield includes backwardly extended grounding arms which also include retainers adapted for engaging into respective apertures on the circuit board. The retainers and retaining apertures secure the connector to the circuit board against vertical as well as forward-backward/leftwards-rightwards horizontal displacement.

Claims

1. An electrical connector for mounting on an edge of a circuit board, the electrical connector comprising:

an electrically insulative body having a plurality of terminal passageways;

a plurality of terminals received withing the terminal passageways, each of the terminals having a tail for connection to the circuit board; and

a conductive shield covering a portion of the electrically insulative body, the conductive shield including at least one grounding arm extending therefrom, the at least one grounding arm being generally parallel to a top surface of the circuit board and including a retainer for engagement with a respective retaining aperture on the circuit board.

2. An electrical connector as defined in claim 1, the body further including a rod extending therefrom for engaging a slot on a leading edge of the circuit board.

3. An electrical connector as defined in claim 1, further including at least one locating block, the at least one locating block including a groove which receives the circuit board.

4. An electrical connector as defined in claim 3, wherein the at least one locating block includes a flexible arm disposed in the groove, the flexible arm including a portion for engaging a respective retaining aperture on the circuit board.

5. An electrical connector as defined in claim 3, further including a rod extending from the body for engaging a slot on a leading edge of the circuit board.

6. An electrical connector as defined in claim 3, wherein the retainer of the at least one grounding arm is a protruded hook having a first end connected to the grounding arm and a second end suspended therefrom.

7. An electrical connector as defined in claim 6, wherein the second end of the protruded hook terminates in a smoothly faced arched face.

8. An electrical connector as defined in claim 3, wherein the retainer of the at least one grounding arm is a semispherical shell which protrudes therefrom.

9. An electrical connector as defined in claim 1, wherein the terminals are arranged into two rows, each the terminal having a clamping tail adapted for clamping on the circuit board and the circuit board is received between the two rows of terminals.

10. An electrical connector as defined in claim 1, wherein the retainer of the at least one grounding arm is a protruded hook having a first end connected to the grounding arm and a second end suspended therefrom.

11. An electrical connector as defined in claim 10, wherein the second end of the protruded hook terminates in a smoothly arched face.

12. An electrical connector as defined in claim 1, wherein the retainer of the at least one grounding arm is a semispherical shell which protrudes therefrom.

13. An electrical connector as defined in claim 3, wherein the at least one grounding arm extends through a passageway in the locating block.

14. An electrical connector comprising:

an electrically insulative body;

a plurality of terminals provided on the body, each the terminal having a tail for surface mount connection to a circuit board; and

a rod extending from the body for engaging a slot on a leading edge of the circuit board.

15. An electrical connector as defined in claim 14, further including a conductive shield covering a portion of the electrically insulative body, the conductive shield including at least one grounding arm extending therefrom, the at least one grounding arm being generally parallel to a top surface of the circuit board and including a retainer for engagement with a respective retaining aperture on the circuit board.

16. An electrical connector as defined in claim 15, wherein the body includes at least one locating block, the locating block including a groove which receives the circuit board and a passageway which receives the at least one grounding arm.

17. An electrical connector as defined in claim 16, wherein the at least one locating block includes a flexible arm disposed in the groove, the flexible arm including a portion for engaging a respective retaining aperture on the circuit board.

18. A conductive shield for use in connection with an electrically insulative body of an electrical connector, the conductive shield comprising:

a conductive plate covering a portion of the electrically insulative body;

at least one grounding arm extending transversely from the conductive plate; and

a retainer provided on the at least one grounding arm for engagement with a respective retaining aperture on a circuit board, the circuit board and the grounding arm being generally parallel to each other.

19. A conductive shield as defined in claim 18, wherein the retainer is a protruded hook having a first end connected to the grounding arm and a second end suspended therefrom, and wherein the second end of the protruded hook terminates in a smoothly arched face.

20. A conductive shield as defined in claim 18, wherein the retainer is a semispherical shell which protrudes from the at least one grounding arm.
