Abstract

A wire plug-in aid sleeve structure for wire connection terminal is assembled in a wire plug-in hole of the terminal. The aid sleeve includes a head section, a belly section connected with the head section and a tail section connected with the belly section. The head section, the belly section and the tail section together define a guide hole for the conductive wire to plug in. The tail section has a first side and a second side positioned on a peripheral section of the guide hole. After the conductive wire passes through the guide hole into the terminal, the metal leaf spring disposed in the terminal is facilitated to press the conductive wire toward the first side or second side.

First claim

What is claimed is:

1. A wire plug-in aid sleeve structure for wire connection terminal, comprising an aid sleeve configured for mounting in a wire plug-in hole of a terminal or a wire plug-in hole of a switch wire connection device, the aid sleeve having a head section, a belly section connected with the head section, and a tail section connected with the belly section, the head section, the belly section and the tail section together defining a guide hole, the tail section having a first side and a second side positioned on a peripheral section of the guide hole and two lateral sides connected with the first and second sides.

2. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 1 , wherein the head section of the aid sleeve is connected with two cylindrical belly sections and two tail sections.

3. A wire plug-in aid sleeve structure for wire connection terminal, comprising an aid sleeve, the aid sleeve having a head section, a belly section connected with the head section, and a tail section connected with the belly section, the head section, the belly section, and the tail section together defining a guide hole, the tail section having a first side and a second side positioned on a peripheral section of the guide hole and two lateral sides connected with the first and second sides,
wherein the head section forms a plate body having an area larger than a cross-sectional area of the belly section, whereby a shoulder section is formed between the head section and the belly section, the tail section protruding from the belly section, the cross-sectional area of the belly section being larger than a cross-sectional area of the tail section, the guide hole being narrowed to form a tapered structure at a junction between the belly section and the tail section.

4. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 2 , wherein the head section has the form of a plate body having an area larger than a cross-sectional area of the belly sections, whereby a shoulder section is formed between the head section and the belly sections, the tail sections protruding from the belly sections, the cross-sectional area of the belly sections being larger than a cross-sectional area of the tail sections, the guide hole being narrowed to form a tapered structure at a junction between the belly section and the tail section.

5. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 1 , wherein at least one of the first and second sides of the tail section is notched, whereby the lateral sides of the tail section is formed as wing structures on two sides of the notch.

6. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 3 , wherein at least one of the first and second sides of the tail section is notched, whereby the lateral sides of the tail section is formed as wing structures on two sides of the notch.

7. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 2 , wherein at least one of the first and second sides of the tail section is notched, whereby the lateral sides of the tail section is formed as wing structures on two sides of the notch, the wing structures of the lateral sides being parallel to a moving path of the metal leaf spring, while the first side and the second side being normal to the moving path of the metal leaf spring.

8. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 4 , wherein at least one of the first and second sides of the tail section is notched, whereby the lateral sides of the tail section is formed as wing structures on two sides of the notch, the wing structures of the lateral sides being parallel to a moving path of the metal leaf spring, while the first side and the second side being normal to the moving path of the metal leaf spring.

9. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 5 , wherein the notch of the first side and the notch of the second side are positioned at the same height.

10. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 6 , wherein the notch of the first side and the notch of the second side are positioned at the same height.

11. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 7 , wherein the notch of the first side and the notch of the second side are positioned at the same height.

12. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 8 , wherein the notch of the first side and the notch of the second side are positioned at the same height.

13. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 5 , wherein the recessed depth of the notch of the first side is larger than the recessed depth of the notch of the second side, whereby the height of the first side is lower than the height of the second side.

14. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 6 , wherein the recessed depth of the notch of the first side is larger than the recessed depth of the notch of the second side, whereby the height of the first side is lower than the height of the second side.

15. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 7 , wherein the recessed depth of the notch of the first side is larger than the recessed depth of the notch of the second side, whereby the height of the first side is lower than the height of the second side.

16. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 8 , wherein the recessed depth of the notch of the first side is larger than the recessed depth of the notch of the second side, whereby the height of the first side is lower than the height of the second side.

17. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 1 , wherein the guide hole is tilted to the first side of the tail section, whereby the height of the first side is lower than the height of the second side.

18. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 2 , wherein the guide hole is tilted to the first side of the tail section, whereby the height of the first side is lower than the height of the second side.

19. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 3 , wherein the guide hole is tilted to the first side of the tail section, whereby the height of the first side is lower than the height of the second side.

20. The wire plug-in aid sleeve structure for wire connection terminal as claimed in claim 4 , wherein the guide hole is tilted to the first side of the tail section, whereby the height of the first side is lower than the height of the second side.
