Abstract

An electrical connector includes a contact holder holding a plurality of contacts and a housing having a chamber holding the contact holder. The housing has a latch pocket along a first side of the housing and a guide pin positioned at or near a second side of the housing. The guide pin has a groove therein. A primary latch is received in the latch pocket and has a deflectable latching beam at a distal end thereof. The latching beam is configured for latching engagement with the mating connector for latching of the first side of the housing to the mating connector. The guide pin is configured to guide mating of the electrical connector with the mating connector. The groove is configured to receive a secondary latch of the mating connector to facilitate latching of the second side of the housing to the mating connector.

Claims

1. An electrical connector comprising:

a contact holder holding a plurality of contacts configured to be mated with corresponding contacts of a mating connector;

a housing having a chamber holding the contact holder, the housing having a latch pocket along a first side of the housing, the housing having a guide pin extending forward therefrom, the guide pin being positioned at or near a second side of the housing opposite the first side, the guide pin having a groove therein; and

a primary latch received in the latch pocket, the primary latch having a deflectable latching beam at a distal end thereof, the latching beam extending forward of the housing and configured for latching engagement with the mating connector to facilitate latching of the first side of the housing to the mating connector;

wherein the guide pin is configured to guide mating of the electrical connector with the mating connector, the groove on the guide pin being configured to receive a secondary latch of the mating connector to facilitate latching of the second side of the housing to the mating connector.

2. The electrical connector of claim 1, wherein the guide pin is cylindrical and is configured to engage the mating connector prior to the primary latch engaging the mating connect.

3. The electrical connector of claim 1, wherein the guide pin is integral with the housing.

4. The electrical connector of claim 1, further comprising a second guide pin having a groove configured to receive a corresponding secondary latch of the mating connector, the second guide pin positioned between the contacts and the primary latch.

5. The electrical connector of claim 1, wherein the housing includes a plurality of cable exits at the second side, the second side being perpendicular to a front of the housing, the guide pin extending from the front.

6. The electrical connector of claim 1, wherein the housing includes a contact shell at a front of the housing, the contact shell providing electrical shielding for the contacts at interfaces of the contacts with the contacts of the mating connector, the guide pin being positioned between the contact shell and the second side, the primary latch being positioned between the contact shell and the first side.

7. The electrical connector of claim 1, wherein the primary latch comprises an actuator, the primary latch being exposed at the first side, the actuator being pressed to deflect the latching beam.

8. The electrical connector of claim 1, wherein the contacts are crimp contacts configured to be crimped to ends of corresponding wires, the wires extending from the chamber of the housing through the second side.

9. The electrical connector of claim 1, wherein the housing comprises a first shell and a second shell forming the chamber, the contact holder being positioned in the chamber between the first and second shells, the housing comprising a contact shell extending forward from the chamber from a front of the housing, the contact shell receiving a portion of the contact holder and portions of the contacts.

10. The electrical connector of claim 9, wherein the contact shell, contact housing and contacts form a contact sub-assembly, the contact sub-assembly having a polarizing feature for polarized mating with the mating connector, the contact sub-assembly being received in the housing in a first orientation and an opposite second orientation to change a mating orientation of the electrical connector with respect to the mating connector.

11. An electrical connector comprising:

a contact holder holding a plurality of contacts configured to be mated with corresponding contacts of a mating connector, the contact holder having a front and a top arranged relative to the front, the contact holder having a guide pin pocket at the front configured to receive a guide pin of the mating connector, the contact holder having a latch pocket configured to receive a primary latch of the mating connector; and

a conductive shield coupled to the exterior of the contact holder, the shield having a top extending along the top of the contact holder and the shield having sides extending along opposite sides of the contact holder, the shield having a primary latch extending from one of the sides of the shield into the latch pocket of the contact holder, the primary latch of the shield being configured to latchably engage the primary latch of the mating connector, the shield having a secondary latch extending from the top of the shield into the guide pin pocket, the secondary latch being configured to engage the guide pin of the mating connector, the secondary latch being configured to resist removal of the guide pin from the guide pin pocket.

12. The electrical connector of claim 11, wherein the conductive shield is stamped and formed with the primary latch and the secondary latch being stamped from a common blank.

13. The electrical connector of claim 11, wherein the conductive shield includes a second primary latch extending from the opposite side of the conductive shield, the second primary latch being received in a second latch pocket of the contact holder.

14. The electrical connector of claim 11, wherein the contact holder includes a plurality of guide pin pockets configured to receive corresponding guide pins of the mating connector, the conductive shield including a plurality of secondary latches extending into corresponding guide pin pockets to engage the corresponding guide pins.

15. The electrical connector of claim 11, wherein the secondary latch includes a tip configured to be received in a groove of the guide pin to latchably secure the secondary latch to the guide pin.

16. The electrical connector of claim 11, wherein the secondary latch is V-shaped and extends inward into the guide pin pocket.

17. The electrical connector of claim 11, wherein the guide pin pocket is positioned between the contacts and the corresponding side of the contact holder.

18. The electrical connector of claim 11, wherein the contacts are right angle contacts having mating ends positioned in a contact cavity of the contact holder and mounting ends opposite the mating ends and configured to be terminated to a circuit board.

19. The electrical connector of claim 11, further comprising a pin organizer having a plurality of openings therethrough, the pin organizer holding circuit board pins of the contacts for termination to a circuit board.

20. The electrical connector of claim 11, wherein the conductive shield includes spring beams extending at least partially through shield openings in the contact holder to engage the mating connector and electrically connect the conductive shield to the mating connector.
