Detailed ways

In order to describe in detail the technical content of the present invention and its achieved purpose and effect, the following will be described in detail in conjunction with the embodiments.

Please refer to FIG. 1 , the terminal assembly 1 includes a follower terminal 11 , a contact terminal 12 and an insulating block 13 .

Please refer to FIG. 2 , the follower terminal 11 has a strip-shaped connecting portion 111 and two contacting portions 112 formed by bending and extending downward from the left and right sides of the connecting portion 111 . The two contacting portions 112 are symmetrical to each other. A contact protrusion 113 is protrudingly provided, and two notches 114 are provided approximately in the middle of the connecting portion 111 . Wherein, the two contact portions 112 can respectively abut against a connecting terminal (not shown in the figure) so as to electrically connect the two connecting terminals (not shown in the figure).

Please refer to FIG. 3 , the contact terminal 12 includes a sheet-shaped base 121 , one side edge of the base 121 is bent forward and extends to form a spring arm 122 , and the left and right ends of the base 121 are respectively bent downward to form a welding portion 124 for welding. The part 124 is used to be welded to other parts. The spring arm part 122 is as large as the middle part to protrude to form an abutment part 123 , and the end of the spring arm part 122 is provided with a round hole 125 . Wherein, the connecting portion 111 of the follower terminal 11 and the end of the elastic arm portion 122 of the contact terminal 12 are fixed together by an insulating block 13 and the follower terminal 11 and the contact terminal 12 are not in contact with each other.

Referring to Fig. 1 to Fig. 6, the manufacturing method of the terminal combination 1 includes the following steps:

Firstly, punch out the first base material 2 comprising several follower terminals 11 and the first strip 21 and the second base material 3 comprising several contact terminals 12 and the second strip 31; the first base material 2 of the first base material 2 A first pre-break 24 is provided between the strip 21 and the follower terminal 11 , and a second pre-break 34 is provided at the connection between the second strip 31 of the second substrate 3 and the contact terminal 12 . The first strip 21 is provided with a first positioning opening 22 and a first positioning hole 23 ; the second strip 31 is provided with a second positioning opening 32 and a second positioning hole 33 .

Secondly, the second base material 3 is fixed on the injection mold (not shown in the figure), and the second positioning opening 32 and the second positioning hole 33 on the second material belt 31 play the role of positioning at this time; The follower terminal 11 on the material 2 is fixed above the end of the spring arm part 122 of the contact terminal 12, and the first positioning opening 22 and the first positioning hole 23 on the first material belt 21 play the role of positioning during this process; The shaped insulating block 13 fixes the substantially middle portion of the follower terminal 11 and the end of the elastic arm portion 122 of the contact terminal 12 together without touching each other.
