Abstract

A wire connection terminal device includes a main body and a pressing/moving unit assembled with the main body. The pressing/moving unit has a shafted section, a cam section connected with the shafted section and a force application section formed on the cam section and a press section formed on the cam section. The cam section can freely rotate or swing within a chamber defined by the main body. A metal leaf spring is disposed in the chamber of the main body for pressing and electrically connecting with a conductive wire. The metal leaf spring is responsive to the motion of the pressing/moving unit to release the conductive wire. The wire connection terminal device improves the shortcomings of the conventional structure that the volume of the case and the operational space are larger and the motional travel is longer.

First claim

What is claimed is:

1. A wire connection terminal device comprising a main body and a pressing/moving unit assembled with the main body, the main body defining a chamber, a metal leaf spring and a terminal pin component being mounted in the chamber, the main body being formed with a wire inlet in communication with the chamber, the pressing/moving unit having a shafted section, a cam section connected with the shafted section and a force application section formed on the cam section and a press section formed on the cam section, the shafted section being pivotally connected on a shaft post of the main body, the cam section being disposed to freely swing within the chamber to alternatively engage and disengage from the metal leaf spring, a length between the force application section and the shafted section being smaller than a length between the press section and the shafted section.

2. The wire connection terminal device as claimed in claim 1 , wherein the terminal pin component is a board body structure with a geometrical configuration, the terminal pin component including a first side formed on a lower side of the board body structure, a second side positioned above the first side, a subsidiary side connected with the first side and terminal pins bent and protruding from the first side, the second side having the form of a slope inclined from the first side, the second side having a tip, an inclination angle of the second side being equal to an angle by which a conductive wire is plugged into the wire inlet of the main body, the first side of the terminal pin component being positioned on a bottom section of the main body with the terminal pins extending out of the main body, the metal leaf spring having a first section, a second section and a bight section connected between the first and second sections, the first section including a head end, the second section including a tail end, the metal leaf spring being mounted on a stake of the main body, whereby the first section and the head end can swing within the chamber, the second section and the tail end of the metal leaf spring respectively contacting the first side and the subsidiary side of the terminal pin component, the head end of the metal leaf spring contacting the second side of the terminal pin component.

3. The wire connection terminal device as claimed in claim 2 , wherein an upper section of the main body is formed with a socket and an insertion section for detachably assembling with a cover corresponding to the socket and the insertion section, the cover being formed with an insertion block, an insertion portion and a shoulder section formed at a rear end of the insertion portion.

4. The wire connection terminal device as claimed in claim 3 , wherein the shafted section of the pressing/moving unit is defined with a swinging center, a length between the force application section and the swinging center being smaller than a length between the press section and the swinging center, whereby the displacement of the force application section is smaller than the displacement of the press section.

5. The wire connection terminal device as claimed in claim 3 , wherein an operational direction of the force application section or the press section is substantially identical to a motional direction of the metal leaf spring.

6. The wire connection terminal device as claimed in claim 2 , wherein the shafted section of the pressing/moving unit is defined with a swinging center, a length between the force application section and the swinging center being smaller than a length between the press section and the swinging center, whereby the displacement of the force application section is smaller than the displacement of the press section.

7. The wire connection terminal device as claimed in claim 6 , wherein an operational direction of the force application section or the press section is substantially identical to a motional direction of the metal leaf spring.

8. The wire connection terminal device as claimed in claim 2 , wherein an operational direction of the force application section or the press section is substantially identical to a motional direction of the metal leaf spring.

9. The wire connection terminal device as claimed in claim 1 , wherein an upper section of the main body is formed with a socket and an insertion section for detachably assembling with a cover corresponding to the socket and the insertion section, the cover being formed with an insertion block, an insertion portion and a shoulder section formed at a rear end of the insertion portion.

10. The wire connection terminal device as claimed in claim 9 , wherein the shafted section of the pressing/moving unit is defined with a swinging center, a length between the force application section and the swinging center being smaller than a length between the press section and the swinging center, whereby the displacement of the force application section is smaller than the displacement of the press section.

11. The wire connection terminal device as claimed in claim 9 , wherein an operational direction of the force application section or the press section is substantially identical to a motional direction of the metal leaf spring.

12. The wire connection terminal device as claimed in claim 1 , wherein the shafted section of the pressing/moving unit is defined with a swinging center, a length between the force application section and the swinging center being smaller than a length between the press section and the swinging center, whereby the displacement of the force application section is smaller than the displacement of the press section.

13. The wire connection terminal device as claimed in claim 12 , wherein an operational direction of the force application section or the press section is substantially identical to a motional direction of the metal leaf spring.

14. A wire connection terminal device comprising a main body and a pressing/moving unit assembled with the main body, the main body defining a chamber, a metal leaf spring and a terminal pin component being mounted in the chamber, the main body being formed with a wire inlet in communication with the chamber, the pressing/moving unit having a shafted section, a cam section extending from a side of the shafted section, a force application section and a press section being formed on the cam section, the shafted section being pivotally connected on a shaft post of the main body, whereby the cam section can freely swing within the chamber between first and second positions, the force application section protruding from the main body when the cam section is at the first position, a length between the force application section and the shafted section being smaller than a length between the press section and the shafted section;
wherein the shafted section is formed with a shaft hole pivotally connected on the shaft post of the main body, a base board being formed on one side of the cam section, one end of the base board protruding to form the press section, a recessed section being formed on one side of the wire inlet.

15. The wire connection terminal device as claimed in claim 14 , wherein the terminal pin component is a board body structure with a geometrical configuration, the terminal pin component including a first side formed on a lower side of the board body structure, a second side positioned above the first side, a subsidiary side connected with the first side and terminal pins bent and protruding from the first side, the second side having the form of a slope inclined from the first side, the second side having a tip, an inclination angle of the second side being
