ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a female terminal.
Electrical connectors are used to connect two or more electrical devices and transfer electrical signals therebetween. Terminals play an important role in signal transfer and the structure of the terminals governs the quality of signal transfer. Taiwan Patent Application No. 86204343 discloses a female terminal as shown in
FIGS. 1 and 2
. The female terminal
10
comprises a rectangular base
12
, a pair of mounting sheets
14
, and a pair of mating sheets
16
. The mounting sheets
14
vertically extend from opposite edges of the base
12
. The mating sheets
16
extend from other opposite edges of the base
12
in a direction opposite from that of the mounting sheets
14
. The mating sheets
16
each form a conjoint portion
18
abutting against each other. A male terminal
20
is inserted between the sheets
18
to electrically connect with the female terminal
10
. However, the male terminal
20
only contacts the conjoint portions
18
along a line; thus, the connection therebetween is unreliable. Hence, an improved female terminal is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a female terminal for making a reliable connection with a corresponding male electrical engaging element.
Accordingly, a female terminal comprises a base, a pair of mounting portions vertically extending from opposite edges of the base and a pair of mating portions extending from other opposite edges of the base in a direction opposite from that of the mounting portions. The mating portion forms a spring arm, a contact section and a guidance portion. The contact sections define an angle in their unengaged states, and the angle between the contact sections approaches zero when a male terminal is inserted into and connects with the female terminal. This allows the male terminal to connect with the contact sections of the female terminals substantially in a plane. Thus, the male terminal and the corresponding female terminal are reliably connected.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
