本考案は雌形端子の改良に関するもので、相手
側端子は雄形接触部を弾圧的に受け入れる雌形端
子のばね状接触部を改良し、その電気的接続性能
の安定向上を図るものである。[Detailed description of the invention] The present invention relates to an improvement of a female terminal.The mating terminal has an improved spring-like contact part of the female terminal which elastically receives a male contact part, and its electrical connection performance is improved. This is intended to improve stability.
近年の端子の小形化傾向に伴つて、雌形端子に
おけるばね状接触部（以下ばね接触部という）
は、そのばね定数が次第に高くなることが避けら
れず、雄形接触部を受け入れたとき、接触荷重が
不足してその電気的接続性能に障害を生ずる問題
がある。 With the trend toward smaller terminals in recent years, the spring-like contact part (hereinafter referred to as spring contact part) in female terminals has become smaller.
It is inevitable that the spring constant will gradually increase, and when a male contact part is accepted, there is a problem that the contact load will be insufficient and the electrical connection performance will be impaired.
即ち、前記の小形化傾向によつて雌形端子を構
成するばね接触部も必然的に小形化し、そのばね
特性は同一荷重に対する撓量が小さくなり、ばね
定数が高くなつて剛性化する傾向が避け得ない。
従つて、例えば第１図に示す様に、側板部３Ａ，
３Ｂを凸状に湾曲させて可撓できるように対向さ
せ、側板部３Ａ，３Ｂ間に板状の雄形接触部（図
示しない）を受け入れ弾着するばね接触部２を有

板部３Ａ，３Ｂ間に間隙Ｃのバラツキならびに雄
形接触部の寸法バラツキによつて、両者の嵌合時
には前記の寸法バラツキの組み合せによつて相当
の嵌合バラツキ、即ち側板部３Ａ，３Ｂの撓量の
変化を生ずる。従つて、前記の小形化傾向によつ
て側板部３Ａ，３Ｂのばね定数が高くなつている
と、前記の嵌合バラツキによる撓量の変化に追髄
して、ばね接触部２と雄形接触部との接触荷重が
必要以上に大きく変動し、電気的接続性能上要求
される最小必要限の接触荷重を満すことのできな
い端子接続を生ずることがある。 In other words, due to the above-mentioned trend toward miniaturization, the spring contact portion that constitutes the female terminal is also inevitably miniaturized, and the spring characteristics tend to be smaller in the amount of deflection for the same load, higher in spring constant, and more rigid. It's unavoidable.
Therefore, for example, as shown in FIG. 1, the side plate portions 3A,
In the female terminal 1, the female terminal 1 has a spring contact part 2 which is curved in a convex shape and is arranged to face each other so as to be flexible, and which receives and snaps a plate-shaped male contact part (not shown) between the side plate parts 3A and 3B. Due to the unavoidable variations in the gap C between the side plate parts 3A and 3B due to the manufacturing process, as well as the dimensional variations in the male contact part, when the two are fitted together, there is a considerable fit variation due to the combination of the above-mentioned dimensional variations. That is, the amount of deflection of the side plate portions 3A, 3B changes. Therefore, when the spring constant of the side plate parts 3A and 3B increases due to the above-mentioned trend toward miniaturization, the change in the amount of deflection due to the above-mentioned fitting variation is compounded, and the male contact with the spring contact part 2 increases. The contact load with the terminal may fluctuate more than necessary, resulting in a terminal connection that cannot meet the minimum contact load required for electrical connection performance.

P1は、従来品の荷重変動量P2の概ね1/2である。 As shown in FIG. 6, the spring contact part 2 having the above structure has a cantilever-shaped thin plate spring body spring contact piece 12 having different fixed ends 11 and 14 and a spring piece 8 having free ends 13 and 9, respectively. When the male contact part is inserted into the apex 15 at the lower center end of the spring contact piece 12, the upward load P acts as an external force, resulting in a composite spring body structure.
Therefore, the total amount of deflection Y of the spring contact portion 2 due to the load P
is the composite amount of the respective deflection amounts of the spring contact piece 12 and the spring piece 8, and compared with a conventional spring contact part with a single spring body with fixed ends, the spring contact part 2 of the present invention has a significantly lower spring resistance. As the constant becomes smaller, elasticity can be increased. Using plates of the same material and thickness to form spring contact parts of the same size, the spring characteristics of the conventional product and the product of the present invention are as shown in Figure 7, and the spring constant of the present product is The load variation of the invented product for the same deflection variation Y
P 1 is approximately 1/2 of the load fluctuation amount P 2 of the conventional product.

定させることができる。 As described above, when using the female terminal with the spring contact portion of the present invention, even if there is unavoidable dimensional variation between the female terminal and the male terminal due to the construction method, the maximum and minimum of the variation can be combined. In the case of fitting variations between the male and female terminals, the amount of variation in the contact load between the male terminal and the spring contact portion 2, which correlates with the amount of deflection variation of the spring contact portion 2, remains within an extremely small range, and the contact load is extremely stable. Therefore, at the upper and lower limits of the fitting variation, the contact load necessary for electrical connection performance can be fully satisfied, and the connection performance of the terminal can be well stabilized.
