Abstract

A connector is provided that includes a female terminal with sacrificial portion. The terminal is configured to minimize arcing between a mating male terminal and an intended contact portion of the female terminal. The female terminal is configured such that arcs between the male terminal and the female terminal occur such that the sacrificial portion of the female terminal experiences any arcing while the intended contact portion remains suitable for reliably engaging the male terminal.

First claim

The invention claimed is:

1. A female terminal, comprising:
a terminal body with a mating end and a circuit connecting end, the mating end being formed of a pair of channels that are generally U-shaped in cross-section, the pair of channels defining a passageway therebetween for receiving a male terminal therein, each channel having a bottom sidewall and two opposed channel sidewalls extending from the bottom sidewall, each bottom sidewall having a slit to define first and second deflection portions of the bottom sidewall;
a primary contact disposed along one of the bottom sidewalls and configured to engage, in operation, a flat surface of the male terminal when the male terminal is inserted into the passageway; and
an arc discharging contact disposed along one of the channel sidewalls forward of the primary contact, the arc discharging contact extending inwardly, such that the male terminal, in operation, comes into contact with the arc discharging contact before coming into contact with the primary contact as the male terminal is inserted into the passageway, whereby any arc discharge between the male and female terminals occurs at the arc discharging contact.

2. The female terminal of claim 1 , wherein the primary contact is formed on each bottom sidewall.

3. The female terminal of claim 1 , wherein the arc discharging contact is formed on each channel sidewall.

4. The female terminal of claim 1 , wherein the terminal body has an intermediate portion between the mating end and the circuit connecting end, the intermediate portion having a projection extending outwardly therefrom.

5. The female terminal of claim 4 , wherein the projection is configured, in operation, to come into contact with shoulders formed in a housing upon the insertion of the female terminal into the housing.

6. A connector, comprising:
a female terminal as defined in claim 1 ; and
an insulative housing generally surrounding at least a portion of the female terminal.

7. The female terminal of claim 1 , wherein the pair of channels are separated by slits, whereby ends of the pair of channels are spaced adjacently to, but apart from, each other.

8. The female terminal of claim 1 , wherein the primary contact is positioned rearward of the first and second deflection portions.

9. The female terminal of claim 1 , wherein the arc discharging contact is positioned rearward of the first and second deflection portions.

10. The female terminal of claim 1 , wherein the arc discharging contact has a circular cross-section that is curved inwardly into the passageway.

11. The female terminal of claim 1 , wherein the primary contact is in the form of a cantilevered beam that extends forwardly from one of the bottom sidewalls toward the corresponding first and second deflection portions.

12. The female terminal of claim 11 , wherein the primary contact extends into the passageway to provide a contact area which is contacted by the male terminal when the male terminal is inserted into the passageway.

13. A female terminal, comprising:
a terminal body with a mating end and a circuit connecting end, the mating end being formed of a pair of channels that are generally U-shaped in cross-section, the pair of channels defining a passageway therebetween for receiving a male terminal therein, each channel having a bottom sidewall and two opposed channel sidewalls extending from the bottom sidewall;
a primary contact disposed along one of the bottom sidewalls and configured to engage, in operation, a flat surface of the male terminal when the male terminal is inserted into the passageway, the primary contact being in the form of a cantilevered beam that extends forwardly from one of the bottom sidewalls toward a position where the male terminal is received within the passageway, the primary contact extending into the passageway to provide a contact area which is contacted by the male terminal when the male terminal is inserted into the passageway; and
an arc discharging contact disposed along one of the channel sidewalls forward of the primary contact, the arc discharging contact extending inwardly, such that the male terminal, in operation, comes into contact with the arc discharging contact before coming into contact with the primary contact as the male terminal is inserted into the passageway, whereby any arc discharge between the male and female terminals occurs at the arc discharging contact.

14. The female terminal of claim 13 , wherein the primary contact is formed on each bottom sidewall.

15. The female terminal of claim 13 , wherein the arc discharging contact is formed on each channel sidewall.

16. The female terminal of claim 13 , wherein the pair of channels are separated by slits, whereby ends of the pair of channels are spaced adjacently to, but apart from, each other.

17. The female terminal of claim 13 , wherein each bottom sidewall has a slit to define first and second deflection portions of the bottom sidewall, the arc discharging contact being positioned rearward of the first and second deflection portions.

18. The female terminal of claim 13 , wherein the arc discharging contact has a circular cross-section that is curved inwardly into the passageway.

19. A connector, comprising:
a female terminal as defined in claim 13 ; and
an insulative housing generally surrounding at least a portion of the female terminal.

20. A female terminal, comprising:
a terminal body with a mating end and a circuit connecting end, the mating end being formed of a pair of channels that are generally U-shaped in cross-section, the pair of channels defining a passageway therebetween for receiving a male terminal therein, each channel having a bottom sidewall and two opposed channel sidewalls extending from the bottom sidewall, the pair of channels being separated by slits, whereby ends of the pair of channels are spaced adjacently to, but apart from, each other;
a primary contact disposed along one of the bottom sidewalls and configured to engage, in operation, a flat surface of the male terminal when the male terminal is inserted into the passageway; and
an arc discharging contact disposed along each of the four channel sidewalls forward of the primary contact, each arc discharging contact extending inwardly, such that the male terminal, in operation, comes into contact with at least one of the four arc discharging contacts before coming into contact with the primary contact as the male terminal is inserted into the passageway, whereby any arc discharge between the male and female terminals occurs at the at least one of four arc discharging contacts.
