Abstract

A connector capable of being mounted onto a substrate is disclosed. Such a connector may include a housing, and a contact mounted within the housing. The contact may include a body, terminal pins extending from a first edge of the body, contact beams extending from a second edge of the body, and a flared portion. The edges of a first contact beam and a second contact beam of the contact beams may be positioned proximate respective adjacent surfaces of the housing. The flared portion may also be positioned proximate a respective adjacent surface of the housing. The relationship between the first contact beam and its respective adjacent surface, the relationship between the second contact beam and its respective adjacent surface, and the relationship between the flared portion and its respective surface may inhibit bowing of the body of the contact when the connector is mounted on the substrate.

Claims

1. An electrical connector capable of being mounted on a substrate, the electrical connector comprising:

a housing defining a housing surface; and

2. The electrical connector of claim 1, wherein the body includes a flared portion that is spaced from an adjacent surface of the housing by a gap of no more than 0.002 inch when the electrical connector is not mounted on the substrate.

3. The electrical connector of claim 1, wherein the housing defines a vertical receptacle housing.

4. The electrical connector of claim 1, wherein the engagement between the at least a portion of one of the contact beams and the housing creates a substantially uniform distribution of stress along the terminal pins as the terminal pins are press-fit mounted into the substrate.

5. The electrical connector of claim 1, wherein the contact comprises a first half and a second half separable from the first half.

6. The electrical connector of claim 1, wherein the housing surface is a first housing surface, and the housing further comprises a second housing surface, and the one of the contact beams is a first contact beam, and contact the further comprises a second contact beam, and at least a portion of the second contact beam is spaced from the second housing surface by a gap of no more than 0.002 inch before the terminal pins are press-fit mounted into the substrate.

7. The electrical connector of claim 6, wherein the contact beams are arranged in a substantially linear array and the first and second contact beams are located at respective first and second outer ends of the substantially linear array.

8. The electrical connector of claim 6, wherein the at least a portion of the first and second contact beams abut the respective first and second housing surfaces when the electrical connector is not mounted on the substrate.

9. The electrical connector of claim 6, wherein the contact beams extend substantially from the body in a first direction, and contact between the contact beams and the respective first and second housing surfaces limits deflection of the contact beams in directions substantially perpendicular to the first direction as the terminal pins are inserted into the penetrations in the substrate.

10. The electrical connector as recited in claim 6, wherein engagement between the at least a portion of the second contact beam and the second housing surface further limits bowing of the contact as the terminal pins are press-fit into the substrate.

11. An electrical connector capable of being mounted on a substrate, the electrical connector comprising:

a housing defining a housing surface; and

a contact mounted in the housing, the contact comprising a body, a plurality of terminal pins extending from a first edge of the body and capable of being received by penetrations in the substrate, and a plurality of contact beams extending from a second edge of the body, wherein the body includes a flared portion, the flared portion being spaced from the housing surface by a gap of no more than 0.002 inch when the electrical connector is not mounted on the substrate such that the flared portion engages the housing surface to limit bowing of the contact as the terminal pins are press-fit mounted into the substrate.

12. The electrical connector of claim 11, wherein the housing defines a vertical receptacle housing.

13. The electrical connector of claim 11, wherein the flared portion abuts the respective adjacent surface of the housing when the electrical connector is not mounted on the substrate.

14. The electrical connector of claim 11, wherein the contact comprises a first half and a second half separable from the first half.

15. A method of restricting bowing in an electrical connector configured for connection to a substrate, the method comprising the steps of:

providing a housing defining opposing first and housing surfaces; and

disposing a contact in the housing, wherein the contact includes a contact body having opposing first and second edges, a plurality of terminal pins extending from the first edge, and a plurality of contact beams extending from the second edge, such that first and second contact beams of the plurality of contact beams are spaced from the first and second housing surfaces, respectively, by a gap of no more than 0.002 inch;

press-fitting the terminal pins into the substrate so as to mount the electrical connector onto the substrate; and

during the press-fitting step, causing the first and second contact beams to engage the first and second housing surfaces so as to limit bowing of the contact.

16. The method as recited in claim 15, wherein the body includes a flared portion and the housing defines a third housing surface, and the positioning step further comprises spacing the flared portion from the third housing surface by a gap of no more than 0.002 inch.

17. The method as recited in claim 15, wherein the first and second contact beams abut the respective first and second housing surfaces.

18. An electrical connector capable of being mounted on a substrate, the electrical connector comprising:

a housing defining a housing surface; and

a contact mounted in the housing, the contact comprising a body, a plurality of terminal pins extending from a first edge of the body and capable of being received by penetrations in the substrate, and a plurality of contact beams extending from a second edge of the body,

wherein at least one of the contact beams engages the housing surface as the terminal pins are press-fit into the substrate so as to cause each of the terminal pins to receive a substantially equal force as the terminal pins are press-fit mounted into the substrate.

19. The electrical connector as recited in claim 18, wherein each body includes a flared portion that is spaced from an adjacent housing surface by a gap of no more than 0.002 inch when the electrical connector is not mounted on the substrate.
