Definitions
- This invention relates to an electrical connector and more particularly to an electrical contact mounted within the connector.
- Electrical connectors generally include a plug and receptacle, each of which has an insert of dielectric material provided with multiple openings within which electrical contacts are retained.
- the insert is introduced into the rear end of a metal shell or housing of the connector where it is held in place by some means, such as a nut.
- Some connectors provide for rearward insertion and front or rear release of electrical contacts, while other connectors provide for front insertion and front or rear release of electrical contacts. These feature are desirable and facilitate the assembly and servicing of the connector. Examples of a prior art electrical connector having insertable and removable contacts may be found in U.S. Patents 3,165;369 entitled “Retention System for Electrical Contacts" issued July 12, 1966; and 3,221,292 entitled “Electrical Connector” issued November 30, 1965.

- This invention provides an electrical connector that has insertable and removable contacts retained and sealed against moisture by a one piece molded rubber insert.

Abstract
Description
- This invention relates to an electrical connector and more particularly to an electrical contact mounted within the connector.
- Electrical connectors generally include a plug and receptacle, each of which has an insert of dielectric material provided with multiple openings within which electrical contacts are retained. The insert is introduced into the rear end of a metal shell or housing of the connector where it is held in place by some means, such as a nut. Some connectors provide for rearward insertion and front or rear release of electrical contacts, while other connectors provide for front insertion and front or rear release of electrical contacts. These feature are desirable and facilitate the assembly and servicing of the connector. Examples of a prior art electrical connector having insertable and removable contacts may be found in U.S. Patents 3,165;369 entitled "Retention System for Electrical Contacts" issued July 12, 1966; and 3,221,292 entitled "Electrical Connector" issued November 30, 1965. In the foregoing patents, the contacts are retained within the connector housing by a retention mechanism and the contacts are sealed from moisture by a separate rubber grommet which fits tightly around the incoming wires to prevent moisture from entering into the area between the contacts. Generally, where removable contacts and a moisture seal is required three or more parts were sandwiched together to accomplish these functions.
- This invention provides an electrical connector that has insertable and removable contacts retained and sealed against moisture by a one piece molded rubber insert. The invention is characterized by a contact having two annular grooves formed by acutely angled flat surfaces that are adapted to mate with a complementary shaped bore in a rubber insert.
- Accordingly, it is an advantage of this invention to provide an insert for an electrical connector that combines the contact retaining functions and moisture sealing functions into a single integral part.
- It is also an advantage of this invention to eliminate the need to sandwich two or more parts together to accomplish the retention and moisture sealing of a contact with an electrical connector.
- It is another advantage of this invention to decrease the cost of assembling an electrical connector.
- It is another advantage of this invention to eliminate the need for adhesives to seal the multiple parts that made up a prior art connector insert.
- FIGURE 1 illustrates an electrical contact.
- FIGURE 2 is a diagrammatic view of an electrical connector incorporating the principles of the invention.
- Referring now to the drawing, FIGURE 1 illustrates a pin-type
electrical contact 20 having a central axis A, aforward mating portion 21, anintermediate portion 22 and a rearwire receiving portion 23. Theintermediate portion 22 includes twogrooves groove flat surfaces angled surface 26 is at an angle of about 30 degrees from the central axis of the contact. Thesurface 27 rearward of theforward surface 26 is at an angle of about 15 degrees from the central axis of thecontact 20. A rearwardly facingshoulder 28 is located between theintermediate portion 22 andend portion 23. The angle of thesurfaces - FIGURE 2 is a diagrammatic view of an electrical connector incorporating the principles of the invention. The electrical connector includes a metal housing 10 and a dielectric insert 30 having mounted therein a male pin-
type contact 20 or a female socket-type contact 20. Each insert 30 includes abore 31 having mounted therein arespective contact 20. Each of thebores 31 in the insert 30 includes two radially inwardly projecting portions or restrictions that mate with theannular grooves contact 20. Eachbore 31 has an inner diameter that is slightly less than the outside diameter of thecontact 20 so as to provide a pressure tight seal around the contact. The angle of thesurfaces grooves surfaces contact 20 from the insert 30 can be changed. To prevent further rearward movement of acontact 20 mounted in the connector insert 30 aplate 40, comprised of a hard dielectric material, is fixedly mounted within the housing 10. Therear shoulder 28 of thecontact 20 abuts against a forwardly facingshoulder 23 on theplate 40 to prevent further rearward movement of thecontact 20 in the insert 30. Theplate 40 acts as a positive stop when acontact 20 is inserted into thebore 31 of the insert 30 from the front of the connector housing 10. The insert 30 is comprised of an elastomer such as rubber and preferably has a durometer of about 65. - While a preferred embodiment of the invention has been disclosed, it will be apparent to those skilled in the art that changes may be made to the invention as set forth in the appended claims and, in some instances, certain features of the invention may be used to advantage without corresponding use of other features. For instance, there could be one groove instead of two grooves in each
contact 20 and the angle of thesurfaces
