本発明は短冊状部品の小幅側面めつき用治具に
関するもので、小幅側面のみを高精度にめつきで
きるようにすることを目的としている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jig for plating narrow-width side surfaces of a strip-shaped component, and its purpose is to enable highly accurate plating of only the narrow-width side surfaces.

に手間がかかる。 Conventionally, as shown in FIG. 1 (plan view), for example, a large number of strip-shaped parts 1 are stacked one on top of the other, resin holding blocks 2 are applied to both ends of the parts, and the parts of the blocks 2 that protrude above and below the parts 1 are held down by bolts 3. The narrow side surface 1a, which requires tightening and plating with nuts 4 and the like, is opposed to the positive electrode 5 in the plating tank. However, in that case, a plating bridge is formed in the gap between the adjacent parts 1, and when the parts 1 are separated, both edges of the narrow side surface 1a are damaged, and the plating accuracy is deteriorated. This tendency becomes more noticeable as the plating film thickness increases. Furthermore, since plating is applied to the upper and lower end surfaces of the component 1, masking may be time-consuming depending on the component.
従来また、めつきを必要とする小幅側面が下端

を積層した場合はブリツジも起こる。 Conventionally, a plating method is also known in which the parts are arranged so that the narrow side surfaces that require plating are located at the lower ends, and the liquid level is controlled so that the plating liquid contacts only the narrow side surfaces. However, in this case, control is required to prevent waving, and it is difficult to employ a stirring method using an air nozzle or the like. Bridging also occurs when parts are stacked as shown in Figure 1.

ンクである。 In FIG. 2 showing the side view, 10 is a rectangular plate-shaped jig body made of a non-conductive material such as vinyl chloride resin, and has a slit 11 penetrating the inside in the front-rear direction (left-right direction in the figure). Preparation, slit 1
The strip-shaped part 13 is pushed forward in the direction of arrow A through the rear opening 12 of the slit 1, and the narrow side surface 13a of the part 13 faces the front opening 14 of the slit 11 and is exposed to the front. In order that the height H 1 of the front opening 14 is slightly lower than the height H 2 of the rear opening 12, the same height (H 2 - 1/1 of H 1 The step 15 of 2) is formed, and the vertical cross-sectional shape of the front end of the slit (section L 1 ) from the step 15 to the front opening 14 is constant; The vertical cross-sectional shape of the slit 11 is such that the width decreases as it goes forward, and the rear half of the slit has tapered inner surfaces 16, 16 that get closer as they go forward (Fig. 4).
is provided. This tapered inner surface 16 has a component 13
The wide side faces 13b of the narrow side faces 13a face each other, and both side edges 17, 17 of the narrow side faces 13a are in pressure contact with the tapered inner surface 16 in the vicinity of the step portion 15. The rear half of the slit in section L2 has a size that accommodates most of the component 13, and a slight gap is created between the upper and lower end surfaces 13c and 13d of the component 13 and the upper and lower surfaces of the slit 11, and the narrow width of the component 13 is The upper and lower ends of the side surface 13a face a stepped portion 15, and a flange 18 formed in front of the stepped portion 15 serves as a stopper for the component 13. That is, when the component 13 is strongly press-fitted forward in the direction of arrow A, the upper and lower ends of the narrow side surface 13a come into pressure contact with the rear surface (step 15) of the collar 18. Jig body 1
The front and back width of 0 is determined so that when the part 13 is mounted as shown in FIGS. It becomes effective when the current-carrying body 19 is pressed against. The current-carrying body 19 is a rod-shaped rigid body, and the part 13
A plurality of the individual jig bodies 10 equipped with the jig bodies 10 are pressed against the rear end surface of the component 13 in an integrated state as shown in FIG. 5, thereby forming a negative electrode. In FIG. 5, a plurality of jig bodies 10 can be integrated by upper and lower bands 20 as shown in FIG. In FIG. 5, 22 is a positive electrode, and 23 is a plating tank.

る。 Each individual plated part 13 is attached to a jig main body 10.
It is installed in the slit 11 as shown in FIGS.
6, and the upper and lower ends of the narrow side surface 13a are set in pressure contact with the rear surface (step 15) of the collar 18, or are set close to facing each other, and the narrow side surface 13a
The tank 23 is positioned facing the electrode 22 as shown in the figure.
is set within. When energized in this state, the jig main body 10 almost completely shields the wide side surface 13b, upper and lower end surfaces 13c, 13d, etc. of the component 13 from the electrode 22, and the collar 18 also shields the upper and lower end surfaces 13c, 13 of the component 13.
It has a masking effect to block the plating on d.

対する部品１３の着脱作業が極めて簡単になる。 As explained above, in the present invention, the rectangular plate-shaped jig main body 10 made of a non-conductive material is provided with a slit 11 into which the strip-shaped component 13 is inserted in the direction of the arrow A from the narrow side surface 13a side. Narrow side surface 13 that requires plating of the strip-shaped part 13
The tapered inner surface 16 where both side edges 17 of a are in pressure contact with each other and the step portion 1 where both ends of the narrow side surface 13a are in pressure contact with or face each other.
5, the narrow side surface 1 that requires plating
High-precision plating can be applied only to 3a, and since the part 13 is completely isolated from the adjacent parts 13, there is no risk of plating bridging occurring between the parts, and a high-precision product can be obtained. . In addition, the collar 18 having the stepped portion 15 has a part 1 relative to the jig 10.
Not only does it serve as a stopper when attaching part 3, but the plating also serves as a stopper when attaching part 13.
Prevent damage caused to people. Further, since the tapered inner surface 16 is provided, the component 13 can be accurately positioned and held at a predetermined position on the jig 10, and the work of attaching and removing the component 13 to and from the jig 10 is extremely simple.
