Abstract

An electrical plug connector for an electrical connector assembly comprises a dielectric housing having at least one cavity which extends inwardly from a mating face of the housing. An electrically conductive socket contact is disposed in the at least one cavity. The socket contact has a generally tubular shape with inner and outer surfaces and an end face which is disposed in a vicinity of the mating face. A first dielectric member is disposed on the socket contact and extends at least over the end face so as to shield the socket contact from inadvertent electrical engagement. For a socket contact of relatively large diameter, a second dielectric member having a post may be disposed centrally within the socket contact to prevent inadvertent engagement with the inner surface thereof.

Claims

1. A plug connector which is matable with a receptacle connector to form an electrical connector assembly, the plug connector comprising:

a dielectric housing having at least one cavity which extends inwardly from a mating face of the housing;

an electrically conductive socket contact disposed in the at least one cavity, the socket contact being generally tubular with inner and outer surfaces and having a contact section adapted for mating with a corresponding pin contact of the receptacle connector, the contact section having an end face disposed in a vicinity of the mating face;

a first dielectric member disposed on the socket contact and extending at least over the end face; and

a second dielectric member disposed within the socket contact the second dielectric member having a post disposed in the contact section so as to define a gap between the post and the inner surface of the contact section;

wherein inadvertent electrical engagement with the socket contact is prevented.

2. The plug connector according to claim 1, wherein the first dielectric member is an insulative coating.

3. The plug connector according to claim 1, wherein the first dielectric member is an insulative cap which is retained on the socket contact by a snap fit means.

4. The plug connector according to claim 3, wherein the snap fit means includes an interengaging ridge and groove formed by the insulative cap and the socket contact.

5. The plug connector according to claim 3, further comprising a louvered metal band disposed within the contact section, and an edge of the insulative cap secures the louvered metal band against withdrawal in one direction.

6. The plug connector according to claim 1, is wherein the second dielectric mender includes a base which is retained in the socket contact by a snap fit means.

7. A plug connector which is matable with a receptacle connector to form an electrical connector assembly, the plug connector comprising:

a dielectric housing having at least one cavity which extends inwardly from a mating face of the housing;

an electrically conductive socket contact disposed in the at least one cavity, the socket contact having a contact section which is adapted for mating with a corresponding pin contact of the receptacle connector;

the contact section having an end face which is recessed from the mating face;

a first dielectric member disposed in the cavity between the mating face and the end face and extending at least over the end face; and

a second dielectric member disposed within the socket contact, the second dielectric member having post disposed in the contact section so as to define a gap between the post and the inner surface of the contact section;

wherein inadvertent electrical engagement with the socket contact is prevented.

8. The plug connector according to claim 7, wherein the second dielectric member includes a base which is retained in the socket contact by a snap fit means.
