Abstract

Female terminal parts (25) comprises a terminal body (28) and a plate spring piece (9). The terminal body (28) is formed with a wire connecting portion (5) and an electric contact portion (3). The electric contact portion (3) is formed with a bottom plate portion (11); a pair of two opposing side plate portions (13, 15); and a pair of two half opposing top plate portions (27, 29). Further, a plate spring piece (9) is formed with a spring body (26) and a pair of lug portions (23) engaged with the lug engagement holes (21) formed in the two side plate portions, respectively when assembled with the terminal body (28). In particular, two opposing cut-off end surfaces (27b, 29b) of the two half top plate portions are chamfered, and a distance (L2) between the two outer ends of the lug portions (23) is determined slightly smaller that another distance (L1) between the two chamfered surfaces (31, 33 ) of the two half top plate portions.

Claims

1. An electrical connector including a group of female terminal parts, comprising:

a terminal body formed with;

a wire connecting portion; and

an electric contact portion, having;

a bottom plate portion having two sides;

a pair of opposing side plate portions extending upward from both sides of the bottom plate portion and further outward away from each other, two lug engagement holes being formed on both of the side plate portions, respectively; and

a pair of opposing top plate half portions extending upward from upper ends of the side plate portions and further inward toward each other and terminating in respective cut-off end surfaces, the top plate portions having a chamfered surface at a ridgeline formed between an inside surfaces and the cut-off end surface; and

a plate spring piece formed with;

a spring body; and

a pair of lug portions engaged with the lug engagement holes formed in the two side plate portions, respectively when assembled with the terminal body, a distance between two outer ends of the lug portions being determined slightly smaller than a distance between the two chamfered surfaces of the two top plate half portions.

2. The female terminal parts of claim 1, wherein each of the chamfered surfaces is a slope surface beginning inward from an outer ridgeline formed between an outside surface and the cut-off end surface of each of the top plate portions.

3. The female terminal parts of claim 2, wherein each of the chamfered surfaces is located in a plane extending from the outer ridgeline to an uppermost edge of the lug engagement hole.

4. The female terminal parts of claim 1, wherein the lug engagement holes are formed on the two side plate portions beginning from the bottom plate portions, respectively.

5. The female terminal parts of claim 1, wherein the two opposing cut-off end surfaces of the two half top plate portions are chamfered by abrading before the female terminal parts are assembled with each other.
