Abstract

A contact module for a component of an electrical connector includes a housing with a bore formed within the housing and a shuttle pin slidably received within the bore of the housing. The contact module may further include a biasing mechanism to bias the shuttle pin towards a mating end of the housing, an electrical contact positioned adjacent the bore of the housing, and a diaphragm positioned within the housing with a fluid channel formed between one side of the diaphragm and the electrical contact.

First claim

What is claimed is:

1. A contact module for a component of an electrical connector, comprising:
a housing including a bore formed within the housing and a mating end;
a shuttle pin slidably received within the bore of the housing;
a biasing mechanism to bias the shuttle pin towards the mating end of the housing;
an electrical contact positioned adjacent the bore of the housing; and
a diaphragm positioned within the housing and radially expandable with respect to the bore, wherein the diaphragm comprises an inner side toward the bore and an outer side away from the bore, wherein the outer side is vented external to the housing, and the electrical contact is in fluid communication with the inner side of the diaphragm through a fluid channel such that the diaphragm allows the electrical contact to displace a fluid from an electrical contact socket to the inner side of the diaphragm.

2. The contact module of claim 1 , further comprising:
a second electrical contact positioned adjacent the bore of the housing and axially along the bore with respect to the first electrical contact; and
a second diaphragm positioned within the housing with a second fluid channel formed between one side of the second diaphragm and the second electrical contact.

3. The contact module of claim 2 , wherein the first diaphragm and the second diaphragm are positioned radially about the bore at substantially the same axial position with respect to the bore.

4. The contact module of claim 1 , wherein the electrical contact and the diaphragm overlap, at least partially, in axial position with respect to the bore.

5. The contact module of claim 1 , further comprising an electrical contact socket configured to receive an electrical line, wherein the electrical contact extends between the bore and the electrical contact socket such that the electrical contact is in electrical communication with the electrical line, and wherein a cross-sectional shape of the electrical contact is wider at the bore than at the electrical contact socket.

6. The contact module of claim 1 , wherein:
the fluid comprises a dielectric medium.

7. The contact module of claim 1 , wherein the component of the electrical connector comprises a plug component, and wherein the electrical contact is configured to form an electrical connection with a contact pin of a receptacle component of the electrical connector.

8. The contact module of claim 7 , further comprising a support pin positioned within the bore of the housing, wherein:
the contact pin is configured to engage and move the shuttle pin within the bore of the housing until the shuttle pin abuts the support pin;
the plug component comprises a plug housing with a bore formed within the plug housing;
the contact module is slidably received within the bore of the plug housing; and
a second biasing mechanism is configured to bias the contact module towards a mating end of the plug housing.

9. The contact module of claim 8 , wherein:
the bore of the plug housing comprises a larger bore formed towards the mating end of the plug housing and a smaller bore formed away from the mating end of the plug housing;
the contact module comprises a stem with the second biasing mechanism positioned about the stem; and
the stem is slidably received within the smaller bore of the plug housing.

10. The contact module of claim 8 , further comprising a second diaphragm positioned within the plug housing of the plug component with one side of the second diaphragm in fluid communication with the bore of the plug housing to compensate for changes in pressure within the bore of the plug housing and with the other side of the second diaphragm vented external to the plug housing.

11. The contact module of claim 8 , wherein the plug housing comprises a first section and a second section, wherein a retaining ring is positioned between the first section and the second section to retain the first section and the second section to each other, and wherein the plug housing comprises a drive slot on an exterior surface thereof.

12. A plug component of an electrical connector, comprising:
a plug housing including a bore formed within the plug housing;
a contact module comprising an electrical contact, the contact module slidably received within the bore of the plug housing;
a contact module biasing mechanism to bias the contact module towards a mating end of the plug housing; and
a plug component diaphragm positioned within the plug housing and radially about the bore of the plug housing, wherein the plug component diaphragm comprises an inner side toward the bore, and an outer side away from the bore, wherein the inner side of the plug component diaphragm is in fluid communication with the bore of the plug housing, and the outer side of the plug component diaphragm is vented external to the plug housing.

13. The plug component of claim 12 , wherein the contact module further comprises:
a contact module housing including a bore formed within the contact module housing;
a shuttle pin slidably received within the bore of the contact module housing;
a shuttle pin biasing mechanism to bias the shuttle pin towards a mating end of the contact module housing;
the electrical contact positioned adjacent the bore of the contact module housing; and
a contact module diaphragm positioned within the contact module housing with a fluid channel formed between one side of the contact module diaphragm and the electrical contact.

14. The plug component of claim 13 , the contact module further comprising:
a second electrical contact positioned adjacent the bore of the contact module housing and axially along the bore with respect to the first electrical contact; and
a second contact module diaphragm positioned within the contact module housing with a second channel formed between one side of the second contact module diaphragm and the second electrical contact;
wherein the first contact module diaphragm and the second contact module diaphragm are positioned radially about the bore at substantially the same axial position with respect to the bore.

15. The plug component of claim 13 , wherein the contact module further comprises:
an electrical contact socket configured to receive an electrical line;
wherein the electrical contact extends between the bore of the contact module housing and the electrical contact socket such that the electrical contact is in electrical communication with the electrical line;
wherein a cross-sectional shape of the electrical contact is wider at the bore than at the electrical contact socket; and
wherein the one side of the contact module diaphragm is in fluid communication with the electrical contact socket.

16. The plug component of claim 12 , wherein:
the bore of the plug housing comprises a larger bore formed towards the mating end of the plug housing and a smaller bore formed away from the mating end of the plug housing;
the contact module further comprises a stem with the contact module biasing mechanism positioned about the stem; and
the stem is slidably received within the smaller bore of the plug housing.

17. The plug component of claim 12 , wherein a fluid that is in fluid communication with the inner side and the bore comprises a dielectric medium.

18. The plug component of claim 12 , further comprising:
a second plug component diaphragm positioned within the plug housing with one side of the second plug component diaphragm in fluid communication with the bore of the plug housing to compensate for changes in pressure within the bore of th
