Extension.
Then, in the example shown in Fig. 5 (C), joggling part 29 is located at the end of the connecting portion 23 extended from linking part 24
Portion's edge, the secondary elastic arm T28 (dotted line represents in figure) before warpage extend towards right, and positioned at the end of above-mentioned connecting portion 23
The broken curve T29-1 of edge is processed towards left warpage.In this embodiment, with Fig. 5 (A), Fig. 5 (B) example compared with, the shape of connecting portion 23
Into bilayer, therefore, the power that circuit substrate is fixed to by being welded to connect becomes much larger.Certainly, in the company with main elastic arm 27
Part corresponding to the lower edge of socket part 23, lower edge is set also may be used from the position that circuit substrate floats as incision secondary elastic arm 28
Only it is welded to connect in the connecting portion 23 of main elastic arm 27.
In addition, in the present embodiment, although not shown, also connecting portion 23 can be made to offset up setting in thickness of slab side.
The above-mentioned example situation provided with two elastic arms like that is self-evident, such as sets joggling part in different positions and formed
In the case of the elastic arm of more than three, position that also can be between linking part and connecting portion carries out thickness of slab side by punching press etc.
Upward skew processing, and connecting portion is offset up relative to linking part side in thickness of slab side by border of the position, so as to
Desired amount is offset relative to arbitrary elastic arm.For example, lower arm part have main elastic arm and secondary elastic arm this
During two arms, connecting portion can be made in both centres.The advantages of offseting connecting portion, is that the connecting portion of circuit substrate welds
The position of the solder joint connect in succession is usually provided in standard defined location, does not change the position and makes the position of above-mentioned connecting portion inclined
Shifting can be tackled.
In the present embodiment, lower arm part is multilayer, but in addition to lower arm part, also other parts can be made to be formed as more
Layer, in addition, can also make terminal be integrally formed into multilayer.For example, in the case where making upper arm parts form multilayer, guiding branch can be improved
The supporting force of bearing portion, so the thickness of slab of terminal can be made thinner.
In the present embodiment, there is the guiding support that supporting is guided to movable link in upper arm parts
Under, in addition to lower arm part, also it can make upper arm parts that two arms are set via joggling part.Now, supporting force can be improved.
In Fig. 1 to Fig. 5 example, terminal has upper arm parts and lower arm part, and both are at the end with free end opposite side
Portion is linked by linking part, forms so-called preceding upset (front flip) form, but the present invention is not limited to this, also may not be used
Upper arm parts are set and only there is lower arm part, and the lower arm part is formed by more than two elastic arms.In addition, shown in Fig. 6
It is so-called after upset (back flip) form terminal in also can apply the present invention, in the terminal of rear flipped form, upper arm parts
21 and lower arm part 22 their length direction centre position by linking part 24 and link, with the convex of long round cross section
When the movable link 3 of wheel portion 37 rotates, the pressed portion 21C of the right-hand member side of upper arm parts 21 is scratched upward because of above-mentioned cam part 37
