Abstract

Provided is a connection terminal including: a conductive plate including a connection unit having a ring shape, and an extension unit integrally formed with the connection unit and extending from one side of the connection unit; and a connection cable electrically connected to the conductive plate, wherein the conductive plate further includes a damping portion formed as a part of the extension unit and bent to protrude along a direction perpendicular to the connection unit.

Claims

1. A connection terminal comprising:

a conductive plate comprising a connection unit that extends in a first direction and an extension unit coupled to the connection unit and extending from one side of the connection unit in the first direction; and

a connection cable electrically connected to the conductive plate,

wherein the conductive plate further comprises a damping portion formed as a part of the extension unit and bent to protrude along a second direction that intersects the first direction so as to damp forces propagating in the first direction;

wherein the damping portion comprises;

a first portion extending along a direction substantially perpendicular to the first direction;

a second portion disposed substantially parallel to the first portion; and

a third portion connecting one end of the first portion and one end of the second portion, and bent with respect to the first and second portions.

2. The connection terminal of claim 1, wherein the damping portion has at least four bent points.

3. The connection terminal of claim 1, wherein the conductive plate has a substantially uniform thickness.

4. The connection terminal of claim 1, wherein the damping portion has a substantially uniform width.

5. The connection terminal of claim 4, wherein the damping portion has a substantially uniform cross-sectional area.

7. The connection terminal of claim 1, wherein the third portion is bent in an arch shape.

8. The connection terminal of claim 1, wherein an end portion of the connection cable contacts one side surface of the damping portion.

9. The connection terminal of claim 8, wherein

the connection cable comprises a wire and a sheath layer for covering at least a part of the wire, and

an end portion of the wire not covered by the sheath layer contacts the one side surface of the damping portion.

10. The connection terminal of claim 1, wherein the connection unit has a ring shape and the extension unit is integrally formed with the connection unit.

6. A connection terminal comprising:

a conductive plate comprising an extension unit and a connection unit that is disposed on a first plane and has a hole at a center; and

a connection cable electrically connected to the conductive plate,

wherein the extension unit of the conductive plate extends from one side of the connection unit in a first direction and is bent to form a damping portion protruding along a second direction that intersects the first plane;

wherein the damping portion comprises;

a first portion extending along a direction substantially perpendicular to the first direction;

a second portion disposed substantially parallel to the first portion; and

a third portion connecting one end of the first portion and one end of the second portion, and bent with respect to the first and second portions.

11. The connection terminal of claim 6, wherein the damping portion has a substantially uniform cross-sectional area.

15. The connection terminal of claim 6, wherein the damping portion has a substantially uniform width.

16. The connection terminal of claim 6, wherein the damping portion has a substantially uniform thickness.

12. A connection terminal comprising:

a conductive plate comprising an extension unit and a connection unit that is disposed on a first plane and has a hole at a center; and

a connection cable electrically connected to the conductive plate,

wherein the extension unit of the conductive plate extends from one side of the connection unit and is bent to form a damping portion protruding along a direction that intersects the first plane;

wherein the damping portion comprises;

a first portion extending along a direction substantially perpendicular to the first plane;

a second portion disposed substantially parallel to the first portion; and

a third portion connecting one end of the first portion and one end of the second portion, and bent with respect to the first and second portions.

13. The connection terminal of claim 12, wherein another end of the first portion is connected to the connection unit and another end of the second portion is adjacently disposed to the connection cable.

14. The connection terminal of claim 12, wherein the third portion is bent in an arch shape.
