Abstract

An electrical connector limiter structure of wire connection terminal is easily operable to enhance the stability of the operation and motion of metal leaf springs. The wire connection terminal includes conductive components mounted in the insulation case and electrical connector assembled with the conductive components. The electrical connector has a limiter for receiving the metal leaf springs and restricting moving path thereof. The limiter is partitioned to define a first space and a second space with fully closed peripheries, in which the metal leaf springs are mounted. The wiring circuits or conductive wires coming from an apparatus can be easily directly plugged into the first and second spaces of the limiter to insert with the metal leaf springs. The limiter serves to prevent the metal leaf springs from deflecting in operation.

First claim

What is claimed is:

1. An electrical connector limiter structure of wire connection terminal, comprising a limiter for receiving metal leaf springs and restricting moving path of the metal leaf springs, the limiter having a first side, a second side connected with the first side, a third side connected with the second side and a fourth side connected with the third side, the first side being bent toward the third side and extending to form a first subsidiary side, the first subsidiary side extending to a position in adjacency to the third side so as to define a first space with a fully closed periphery, the fourth side being bent toward the second side and extending to form a fifth side, the fifth side being bent toward the third side and extending to form a second subsidiary side, the second subsidiary side extending to a position in adjacency to the third side so as to define a second space with a fully closed periphery.

2. The electrical connector limiter structure of wire connection terminal as claimed in claim 1 , wherein the first side and the first subsidiary side contain an angle selected from a group consisting of an acute angle, a right angle and an obtuse angle and the fifth side and the second subsidiary side contain an angle selected from a group consisting of an acute angle, a right angle and an obtuse angle, the first and second subsidiary sides being side by side arranged in parallel to each other.

3. The electrical connector limiter structure of wire connection terminal as claimed in claim 1 , wherein the third side is formed with a window and at least one of the first and second subsidiary sides is formed with a protrusion end extending into the window.

4. The electrical connector limiter structure of wire connection terminal as claimed in claim 1 , wherein the first subsidiary side has a length equal to a length of the second subsidiary side.

5. The electrical connector limiter structure of wire connection terminal as claimed in claim 3 , wherein the protrusion end is formed on the first subsidiary side, whereby the total length of the first subsidiary side and the protrusion end is larger than the length of the second subsidiary side.

6. The electrical connector limiter structure of wire connection terminal as claimed in claim 1 , wherein two leg sections respectively protrude from a bottom end of the second side and a bottom end of the fourth side and finger sections are respectively formed on lateral sides of the leg sections, one of an upper end and a lower end of the third side being perpendicularly bent to form an extension section.

7.

8. The electrical connector limiter structure of wire connection terminal as claimed in claim 4 , wherein two leg sections respectively protrude from a bottom end of the second side and a bottom end of the fourth side and finger sections are respectively formed on lateral sides of the leg sections, one of an upper end and a lower end of the third side being perpendicularly bent to form an extension section.

9. The electrical connector limiter structure of wire connection terminal as claimed in claim 5 , wherein two leg sections respectively protrude from a bottom end of the second side and a bottom end of the fourth side and finger sections are respectively formed on lateral sides of the leg sections, one of an upper end and a lower end of the third side being perpendicularly bent to form an extension section.

10. The electrical connector limiter structure of wire connection terminal as claimed in claim 1 , wherein a notch is formed at a junction between an upper end of the second side and an upper end of the third side and another notch is formed at a junction between the third side and the fourth side, a finger section being formed on a lateral side of the upper end of the second side in a position adjacent to the notch between the second and third sides, another finger section being formed on a lateral side of the upper end of the fourth side in a position adjacent to the notch between the third side and the fourth side, one of an upper end and a lower end of the third side being perpendicularly bent to form an extension section.

11. The electrical connector limiter structure of wire connection terminal as claimed in claim 3 , wherein a notch is formed at a junction between an upper end of the second side and an upper end of the third side and another notch is formed at a junction between the third side and the fourth side, a finger section being formed on a lateral side of the upper end of the second side in a position adjacent to the notch between the second and third sides, another finger section being formed on a lateral side of the upper end of the fourth side in a position adjacent to the notch between the third side and the fourth side, one of an upper end and a lower end of the third side being perpendicularly bent to form an extension section.

12. The electrical connector limiter structure of wire connection terminal as claimed in claim 4 , wherein a notch is formed at a junction between an upper end of the second side and an upper end of the third side and another notch is formed at a junction between the third side and the fourth side, a finger section being formed on a lateral side of the upper end of the second side in a position adjacent to the notch between the second and third sides, another finger section being formed on a lateral side of the upper end of the fourth side in a position adjacent to the notch between the third side and the fourth side, one of an upper end and a lower end of the third side being perpendicularly bent to form an extension section.
