を備えたモールド挿入型電気接点６′を作っていた。Conventionally, the second method is to make this mold insertion type electrical contact.
As shown in FIG. 2A, a clad contact material 3 made by brazing a contact material and a base material 2 is entirely laced to insert a mold having a large-diameter portion 5 having a step 4 at an intermediate portion as shown in FIG. 2B. A die electrical contact 6 or a recess 8 in the center of the top of the head of a modified rivet die base material 7 as shown in Figure 3a.
A small rivet type clad contact material 9 was press-fitted into the legs to form a mold insertion type electric contact 6'having a large diameter portion having a step 4 in the middle as shown in FIG. 3b.

らである。However, although the manufacturing method by the lace processing can obtain the mold insertion type electric contact 6 with high dimensional accuracy, not only is a large amount of scrap generated and the cost is high,
Productivity was bad. Further, the manufacturing method in which the small rivet-type clad contact material 9 is press-fitted into the concave portion 8 at the center of the upper surface of the irregular-shaped rivet-type base material takes too much time to produce the irregular-shaped base material 7, and the productivity is extremely poor. It was This is because the special shape of the mold insertion type electrical contacts 6 and 6'has an extremely high upsetting ratio (processing rate), and thus normal header processing cannot be performed.

ある。(Means for Solving Problems) The method for producing a mold insertion type electrical contact of the present invention for solving the above problems requires a base wire material whose diameter is selected so that the upsetting ratio is 4.0 or less. The end portion of the base material obtained by cutting into a length is extruded forward to project small diameter leg portions,
Next, a clad contact material is made by brazing a contact material of the same diameter to the tip of this base material, and then the middle part of the clad contact material is preformed by header processing to form a lump-shaped bulge. It is characterized in that the bulging portion having the rear aggregate shape is finished by press working to form the stepped large diameter portion.
（作用） 上述の如く本発明のモールド挿入型電気接点の製造方

入型電気接点が能率良く製造される。(Operation) As described above, in the method for manufacturing the mold insertion type electrical contact of the present invention, the diameter of the base material as a raw material is selected so that the upsetting ratio is 4.0 or less, so that the end portion of the base material is moved forward. By extrusion molding, small-diameter legs can be easily projected. Further, the contact material can be easily brazed to the tip of the base material. Furthermore, when the intermediate part of this clad contact material is header processed to form a lump-shaped bulge, and the lump-shaped bulge is pressed to form a large diameter stepped portion, the volume of each process is Very few. Therefore, the mold insertion type electrical contact with high dimensional accuracy can be manufactured easily and reliably with high efficiency.
