Abstract
An elastic terminal ferrule includes an annular body, a limit structure formed on the annular body, and a mating limit structure formed on the annular body for mating with the limit structure. When the annular body is in a natural state without radial expansion, the limit structure and the mating limit structure are spaced apart from each other in a circumferential direction. When the outer diameter of the annular body is expanded to a predetermined value, the limit structure and the mating limit structure abut against each other in the circumferential direction to prevent further radial expansion of the elastic terminal ferrule.
Claims20
An elastic terminal ferrule, comprising:
- an annular body having a pair of ends which are free in a circumferential direction of the annular body;
- a limit structure formed on the annular body near one of the ends of the annular body;
- and
- a mating limit structure formed on the annular body for mating with the limit structure, the limit structure and the mating limit structure are spaced apart from each other in the circumferential direction when the annular body is in a natural state without radial expansion, and the limit structure and the mating limit structure abut against each other in the circumferential direction to prevent further radial expansion of the elastic terminal ferrule when an outer diameter of the annular body is expanded to a predetermined value, the annular body includes a first ring and a second ring, the first ring has a first root and a first end movable in the circumferential direction relative to the first root, the second ring is axially adjacent to the first ring and connected to the first root.
A terminal assembly, comprising:
- a terminal having a cylindrical part located at an end and adapted to mate with a mating terminal, a plurality of axial extension slots are formed on the cylindrical part;
- and
- an elastic terminal ferrule sleeved on an outside of the cylindrical part of the terminal to prevent the cylindrical part from being excessively expanded radially, the elastic terminal ferrule includes:
- an annular body having a pair of ends which are free in a circumferential direction of the annular body;
- a limit structure formed on the annular body near one of the ends of the annular body;
- and
- a mating limit structure formed on the annular body for mating with the limit structure, the limit structure and the mating limit structure are spaced apart from each other in the circumferential direction when the annular body is in a natural state without radial expansion, and the limit structure and the mating limit structure abut against each other in the circumferential direction to prevent further radial expansion of the elastic terminal ferrule when an outer diameter of the annular body is expanded to a predetermined value, the annular body includes a first ring and a second ring, the first ring has a first root and a first end movable in the circumferential direction relative to the first root, the second ring is axially adjacent to the first ring and connected to the first root.
