Abstract

A socket contact (4) comprises a unitary contact body (12) including a tubular body portion (20) having a wall (22) which defines an interior space (24) and an open end (25) which permits insertion of a lead (11) of a mating contact into the interior space. The unitary contact body further includes a spring finger (30) extending into the interior space for engagement with the lead of the mating contact, and a shield (40) partially covering the open end and arranged to guide the lead into the interior space. The shield (40) prevents stubbing of the spring finger (30) during insertion of the lead (11).

Claims

1. A socket contact comprising:

a unitary contact body including a tubular body portion having a wall which defines an interior space and an open end which permits insertion of a mating contact into the interior space, a spring finger extending into the interior space for engagement with the mating contact, and a shield partially covering the open end, the shield including a pair of flaps having ends which abut over the open end, and a cutout in the abutting ends provides an opening for the mating contact to enter the interior space, whereby the shield guides the mating contact into the interior space and prevents stubbing of the spring finger during insertion of the mating contact.

2. The socket contact according to claim 1, wherein the unitary contact body includes a solder tab.

3. The socket contact according to claim 1, wherein the spring finger is defined by a segment of the wall which is bent into the interior space.

4. The socket contact according to claim 3, wherein the wall segment is a longitudinally extending strip of the wall.

5. The socket contact according to claim 4, wherein the strip has a connection with the wall at a longitudinal distance from the open end, and the strip has a contact portion disposed in the interior space for engaging the mating contact at a relatively shorter longitudinal distance from the open end.

6. The socket contact according to claim 4, wherein a pair of the spring fingers are mutually opposed in the interior space for engaging the mating contact therebetween.

7. The socket contact according to claim 1, wherein a flange extends outwardly from the wall of the tubular body portion.

8. The socket contact according to claim 7, wherein the pair of flaps are connected to the flange at respective reverse bends.

9. An electrical connector comprising:

a dielectric housing holding a plurality of socket contacts, each of the socket contacts comprising a unitary contact body including a tubular body portion having a wall which defines an interior space and an open end which permits insertion of a mating contact of a mating electrical connector into the interior space, a spring finger extending into the interior space for engagement with the mating contact, and a shield partially covering the open end, the shield including a pair of flaps having ends which abut over the open end, and a cutout in the abutting ends provides an opening for the mating contact to enter the interior space, whereby the shield guides the mating contact into the interior space and prevents stubbing of the spring finger during insertion of the mating contact.

10. The electrical connector according to claim 9, wherein the unitary contact body includes a solder tab.

11. The electrical connector according to claim 9, wherein the spring finger is defined by a segment of the wall which is bent into the interior space.

12. The electrical connector according to claim 11, wherein the wall segment is a longitudinally extending strip of the wall.

13. The electrical connector according to claim 12, wherein the strip has a connection with the wall at a longitudinal distance from the open end, and the strip has a contact portion disposed in the interior space for engaging the mating contact at a relatively shorter longitudinal distance from the open end.

14. The electrical connector according to claim 12, wherein a pair of the spring fingers are mutually opposed in the interior space for engaging the mating contact therebetween.

15. The electrical connector according to claim 9, wherein a flange extends outwardly from the wall of the tubular body portion.

16. The electrical connector according to claim 15, wherein the pair of flaps are connected to the flange at respective reverse bends.

17. An electrical connector comprising:

a dielectric housing holding a plurality of socket contacts, each of the socket contacts comprising a unitary contact body including a tubular body portion having a wall which defines an interior space and an open end which permits insertion of a mating contact of a mating electrical connector into the interior space, a spring finger extending into the interior space for engagement with the mating contact, and a shield which is arranged to guide the mating contact into the interior space, the shield including a pair of flaps of material each extending along a respective course first outwardly from the wall of the tubular body portion and then through a reverse bend back toward the wall to a position partially covering the open end, the pair of flaps having ends which abut over the open end, and a cutout in the abutting ends provides an opening for the mating contact to enter the interior space.
