側を覆うことを特徴とするものである。 In the method of manufacturing an electric contact according to the present invention, first, a contact mounting hole 2 is bored in a thin plate base material 1' as shown in FIG. As shown in Figure C, the leg part 3a of the rivet type contact material 3 is inserted into the contact mounting hole 2 of the base material 1', and the upper side of the slit 5 is covered with the head 3b. The leg portion 3a is temporarily tightened to the lower peripheral edge of the contact mounting hole 2 to cover the lower side of the slit 5.

４′が得られる。 In this way, in the method of manufacturing an electrical contact of the present invention, the slit 5 is also formed at the peripheral edge of the contact mounting hole 2 of the thin plate base material 1', so that the rivet type contact material 3 is formed in the contact mounting hole 2. When the leg part 3a of the thin plate base material 1' is inserted and the leg part 3a is temporarily tightened, the
Even if the contact mounting hole 2 is pushed outward, the slit 5 can absorb the deformation of the peripheral edge of the contact mounting hole 2. Therefore, the periphery of the contact mounting hole 2 is not warped, twisted, distorted, or broken, so the contact material 3 is fixed in a predetermined position without tilting, and the upper contact mounting hole 2 Since the peripheral slit 5 is covered on both upper and lower sides by the head 3b of the rivet-type contact member 3 and the temporarily tightened portion 3c of the leg 3a, an electrical contact 4' with high dimensional accuracy and good quality can be obtained.

法精度が悪く、品質不良であつた。 However, when we inspected the quality of 100 electric contacts of the example and the conventional example obtained in this way, we found that in the electric contact 4' of the example, the deformation of the peripheral edge of the contact mounting hole 2 of the base material 1 was caused by the slit 5. The slit 5 is almost completely covered by the absorption, and there is no warpage, twisting, distortion, or breakage of the periphery, and the contact material 3 does not tilt relative to the base material 1. horizontally and completely fixed in the contact mounting hole 2,
While all of the electrical contacts had extremely high dimensional accuracy and were of good quality, the conventional electrical contact 4 had warped, twisted, or distorted edges around the contact mounting hole 2 of the base material 1. As many as 25 out of 100 electrical contacts 4 deformed or broke due to contact, and the contact material 3 of all 25 electrical contacts 4 was tilted or moved without being fixed in the contact mounting hole 2. However, the dimensional accuracy was extremely poor and the quality was poor.

良いものである。 In the above embodiment, the slit 5 formed at the periphery of the contact mounting hole 2 of the base material 1 has an arc shape with the contact mounting hole 2 as the center, but the slit 5 is not limited to this, and the slit 5 may be formed in the leg of the rivet type contact material 3. Depending on the cross-sectional shape of the portion 3a, changes may be made as appropriate as shown in FIGS. 3a, b, c, and d. In short, any shape of the slit 5 can be used as long as it can absorb the deformation of the periphery of the contact mounting hole 2 when the leg 3a of the rivet type contact material 3 is temporarily tightened to the periphery of the lower surface of the contact mounting hole 2 of the base material 1. But it's a good one.

得ることができるという優れた効果がある。 As detailed above, according to the method of manufacturing an electrical contact of the present invention, even if the rivet-type contact material is inserted into the contact mounting hole of the thin plate base material and temporarily tightened, the peripheral edge of the contact mounting hole will not be deformed or broken. There is an excellent effect in that the contact material can be mounted horizontally and completely fixed to the base material, and an electrical contact with extremely high dimensional accuracy and good quality can be easily obtained.
