Abstract

A connection terminal comprises a terminal connection unit and a blade spring. A male terminal is inserted in the terminal connection unit. The blade spring is disposed in the terminal connection unit and press-contacts with the male terminal by means of reacting force generated by flexure deformation thereof. Spring strength of a front area of the blade spring is weaker than that of a rear area of the blade spring, wherein the front area is located at one side of the blade spring from which the male terminal is inserted in the terminal connection unit.

Claims (12)

1. A connection terminal comprising:

a terminal connection unit in which a male terminal is inserted, the terminal connection unit comprising:

a base portion;

a pair of side wall portions installed to both ends of the base portion in a standing manner;

an upper wall portion extending from an upper end of one of the side wall portions toward the other of the side wall, portions;and

a pair of sandwiching plates extending from both front ends of the upper wall portion toward a center portion of the terminal connection unit, the front end being located at one side of the upper wall from which the male terminal is inserted in the terminal connection unit, and

a blade spring disposed in the terminal connection unit, sandwiched between the upper wall portion and the sandwiching plates at the front end thereof, and press-contacting with the male terminal by means of reacting force generated by flexure deformation thereof,

wherein spring strength of a front area of the blade spring is weaker than that of a rear area of the blade spring, the front area being located at one side of the blade spring from which the male terminal is inserted in the terminal connection unit.

2. The connection terminal according to claim 1 , wherein a width of the front area is smaller than that of the rear area.

3. The connection terminal according to claim 1 . wherein a thickness of the front area is smaller than that of the rear area.

4. The connection terminal according to claim 1 , wherein a length of the front area is larger than that of the rear area.

5. The connection terminal according to claim 1 , wherein the blade spring can freely move at the rear area thereof.
