Flexible terminals with lateral and oblique bending structures

Abstract

This invention provides a flexible terminal with lateral and oblique bending structures, comprising an electrical connection portion, a contact portion, a relay portion connected to the electrical connection portion, and an elastic structure connecting the contact portion and the relay portion. The elastic structure has at least a first bending portion with a lateral bending and a second bending portion with an oblique bending. Through the geometrical arrangement of the lateral and oblique bending, when subjected to external forces, the first bending portion can suppress oblique torsion, achieving better spatial avoidance and electrical connection stability.

Claims

1. A resilient terminal having a lateral and oblique bending structure, comprising: An electrical connection portion is disposed at one end of the resilient terminal; a contact portion is disposed at the other end of the resilient terminal; a relay portion is connected to the electrical connection portion and extends along a height direction; and an elastic structure is connected between the relay portion and the contact portion and extends from the relay portion toward the contact portion, comprising: a first bending portion that bends laterally relative to the height direction; a first support arm that connects to the first bending portion and extends along the bending direction of the first bending portion; a second bending portion that connects to the first support arm and bends obliquely relative to the first support arm; and a second support arm that connects to the second bending portion and extends along the bending direction of the second bending portion.

2. The resilient terminal as described in claim 1, wherein, The first turning part is connected to the relay part, and the second arm is connected to the contact part.

3. The resilient terminal as described in claim 1, wherein, The elastic structure further includes: a bending portion disposed between the first turning portion and the first support arm, and bent at an offset relative to the turning direction of the first turning portion, so that the first support arm extends along the offset direction of the bending portion.

4. The resilient terminal as described in claim 1, wherein, The height direction of the relay section is orthogonal to the turning direction of the first turning section.

5. The resilient terminal as described in claim 1, wherein, The width of the contact portion is different from the width of the second turning portion.

6. The resilient terminal as described in claim 1 or 5, wherein, The second arm is connected to the contact portion, and the width of the second arm gradually decreases along the extension direction from the second turning portion to the contact portion.

7. The resilient terminal as described in claim 1, wherein, The width of the first bend is different from the width of the second bend.

8. The resilient terminal as described in claim 1 or 7, wherein, The width of the first arm gradually decreases from the first bend to the second bend along the extension direction.

9. The resilient terminal as described in claim 1, wherein, The width of the electrical connection portion differs from the width of any other segment of the resilient terminal.

10. The resilient terminal as described in claim 1, wherein, The contact portion has an inner side and an outer side opposite to each other, and further includes: a contact end that bends from the end of the contact portion toward the inner side to form a bent surface on the outer side of the contact portion.

11. The resilient terminal as described in claim 10, wherein, The two furthest edges of the first turning portion define a first projection range along the height direction; the two furthest edges of the contact end define a second projection range along the height direction; wherein the first projection range and the second projection range do not overlap.

12. The resilient terminal as described in claim 1, wherein, The relay section further includes: at least one thorn portion disposed on at least one side of the relay section.
