Electrical terminal with layered springs
View Patent ↗Disclosed herein is an electrical terminal. The electrical terminal includes a frame, a first spring, and a second spring. The frame has a receptacle section adapted to receive a male contact. The first spring is movably captured in the receptacle section. The second spring is movably captured in the receptacle section. The second spring has a first side and a second side. The first side slidably contacts the first spring. The second side comprises a contact surface for contacting the male contact when the male contact is inserted into the receptacle section.
1. An electrical terminal comprising:
a frame with a receptacle section adapted to receive a male contact;
a first spring movably captured in the receptacle section; and
a second spring movably captured in the receptacle section, wherein the second spring has a first side and a second side, wherein the first side slidably contacts the first spring, and wherein the second side comprises a contact surface for contacting the male contact when the male contact is inserted into the receptacle section, wherein the first and second springs are individual separate members from the frame.
2. The electrical terminal of claim 1 wherein the first spring and the second spring are leaf springs.
3. An electrical terminal comprising:
a frame with a receptacle section adapted to receive a male contact;
a first spring movably captured in the receptacle section; and
a second spring movably captured in the receptacle section, wherein the second spring has a first side and a second side, wherein the first side slidably contacts the first spring, and wherein the second side comprises a contact surface for contacting the male contact when the male contact is inserted into the receptacle section,
wherein the frame further comprises holes and the first spring and the second spring each have extending lateral portions received in holes of the frame.
4. The electrical terminal of claim 1 wherein the first spring comprises a first side and a second side, and wherein the first side of the second spring slidably contacts a majority of the second side of the first spring.
5. The electrical terminal of claim 1 wherein the frame further comprises a fixed contact surface within the receptacle section.
6. The electrical terminal of claim 5 wherein the first spring and the second spring are adapted to deflect when the male contact is inserted into the receptacle section.
7. An electrical connector comprising a housing and at least one electrical terminal as in claim 1 mounted inside the housing.
8. An electrical terminal comprising:
a frame with a receptacle section adapted to receive a male contact, wherein the receptacle section comprises a fixed contact surface; and
a plurality of individual separate spring, which are separate members from the frame connected to the frame, wherein the plurality of springs are disposed adjacent to one another, and wherein the springs are configured to deflect away from the fixed contact surface in response to reception of the male contact in the receptacle section.
9. The electrical terminal of claim 8 wherein the plurality of separate springs are separate leaf springs.
10. The electrical terminal of claim 9 wherein the plurality of separate springs are each in sliding contact with one another.
11. The electrical terminal of claim 10 wherein the separate springs are substantially identical to each other and have a general “V” shape.
12. The electrical terminal of claim 8 wherein each of the plurality of separate springs comprise a center section having lateral sides and wherein the frame further comprises side holes for movably capturing the lateral sides of the plurality of separate springs.
13. An electrical connector comprising a housing and at least one electrical terminal as in claim 8 mounted inside the housing.
14. An electrical terminal comprising:
a frame with a receptacle section adapted to receive a male contact, wherein the receptacle section comprises a fixed contact surface; and
a leaf spring arrangement comprising at least two separate leaf spring elements disposed within the receptacle section, wherein the leaf spring arrangement is oriented opposite to the fixed contact surface, wherein the leaf spring arrangement is configured to provide a contact force on the male contact when the male contact is received between the leaf spring arrangement and the fixed contact surface, and wherein the separate leaf spring elements are substantially identical to each other, and wherein the separate leaf spring elements are stacked against one another.
15. The electrical terminal of claim 14 wherein the separate leaf spring elements are each in sliding contact with one another.
16. The electrical terminal of claim 14 wherein the leaf spring arrangement comprises means for reducing stress wherein the means for reducing stress comprises the separate leaf spring elements being slidably arranged to one another.
17. The electrical terminal of claim 1 wherein the first and second springs are substantially identical and stacked against each other.
18. The electrical terminal of claim 17 wherein a free end of the first spring is slidably located against the frame.
19. The electrical terminal of claim 18 wherein the first and second springs each have front and rear free ends located in the receptacle section of the frame.
20. The electrical terminal of claim 19 wherein middle sections of the first and second springs directly movable connect the springs to the frame.
21. The electrical terminal of claim 14 wherein the leaf spring arrangement is further configured to deflect when the male contact is received between the leaf spring arrangement and the fixed contact surface.
22. The electrical terminal of claim 14 wherein the frame further comprises a side hole movably capturing a portion of the leaf spring arrangement therein.
23. An electrical connector comprising a housing and at least one electrical terminal as in claim 14 mounted inside the housing.
24. The electrical terminal of claim 14 wherein middle sections of at least one of the springs directly movable connect the springs to the frame.
25. The electrical terminal of claim 24 wherein an opposite second free end of the first spring comprises tabs rotatably captured in pockets of the frame.
