BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pin transformer and a method of manufacturing the same. In particular, the above-described pins are formed with a plurality of protrusions formed at predetermined intervals at the same time as the press mold of the pin transformer used as a connection terminal of an electric / electronic device. When the transformer is rolled around, a gap is created by the above-mentioned multiple projections.

In general, wires are used as connection terminals for electronic components such as VCR heads, but this is inefficient because all assembly work is performed by hand and automation due to component mounting is difficult.

Accordingly, in order to automate and efficiently use the above-described parts mounting and all processes, terminal pins are manufactured and used instead of the existing wires.

However, in order to manufacture such terminal pins, design the product before manufacturing the mold of the product first, manufacture the press mold according to the design drawing, and then continually punch the brass plate material into the required product shape and then surface the surface for easy soldering. In the process of processing, conventionally, the continuous pin trans member passes through the container containing the plating liquid at a constant speed through the conveying mechanism to perform surface treatment, or the pin trans is cut to a predetermined length and immersed in the plating liquid individually. Because of the treatment, the manufacturing process is complicated, and the plating thickness is severely varied, resulting in a decrease in productivity and a large tolerance.

In order to solve the above-mentioned shortcomings, an object of the present invention is to improve productivity by improving the shape of the pin transformer and the plating treatment process by the press die in the manufacturing process of connecting terminals of electronic components.

In order to achieve the above object, the present invention is a conventional pin transformer manufactured by a press die in accordance with the electronic component design, the center guide member 2 and the both side guide member (3) of the pin transformer (1) ), (4) and a plurality of easy to cut pin members 5 are arranged and formed evenly to correspond to each other, but a plurality of holes arranged and drilled so as to maintain a predetermined interval in the central guide member (2) A plurality of elliptical protrusions 7 arranged and protruded so as to maintain a predetermined interval therebetween, and linear guide members 3 and 4 in a straight line corresponding to the protrusions 7 of the central guide member 2; A plurality of circular protrusions 8, 9 arranged and protruded so as to maintain a predetermined distance between the pins are provided.

In addition, the electronic parts are designed, and a plurality of holes 6 and pin members 5 are formed in predetermined portions of the brass sheet material according to the product design, and at the same time, the center and both side guide members 2, 3, A plurality of protrusions 7, 8, and 9 are press-molded so that the protrusions 7, 8, and 9 protrude upwardly on one surface of (4), and the gaps are formed by the plurality of protrusions 7, 8, and 9 described above. 10) After the SNPB plating process of the wound pin transformer body 12, the injection molding is performed such that the holding member 15 is formed at a predetermined position with a synthetic resin so that the plurality of pin members 5 are insulated and fixed one by one. And the center and both side guide members 2, 3, and 4 described above are cut using a jig (not shown).

According to the above structure, since a number of protrusions were formed on one surface of the pin transformer at the same time as the press mold of the product, a gap between each surface was formed by the protrusion, so that the wound pin trans body was immersed in the plating solution. Since many products can be plated at the same time, the thickness of the coating can be uniformized, and productivity can be improved by removing warpage and simplifying the manufacturing process.

EXAMPLE

Hereinafter, embodiments of the present invention will be described in detail by the accompanying drawings. (1) shows a plurality of holes (6) evenly drilled in the center guide member (2) at predetermined intervals by a press mold in accordance with the product design, arranged in a row, between each of the arranged holes (6) There are a plurality of projections 7 protruding in an elliptical shape toward one side upward in a row.

In addition, the lateral guide members 3 and 4 each of the plurality of protrusions 8 which protrude in a small circle toward one side upward in a straight line corresponding to the protrusions 7 of the center guide member 2 described above. And (9) are arranged in a line.

In addition, a plurality of pin members 5 are arranged and formed correspondingly between the center guide member 2 and the both side guide members 3 and 4 so as to be easily cut.

Although the pin transformer 1 of the present invention described above is schematically illustrated by cutting only a part of the pin transformer 1 as described above, the pin transformer 1 press-molded as described above is rolled by the roll 11. It becomes the state of.

Accordingly, the rolled fin trans body 12 is provided with a gap 10 between the surfaces abutted by a plurality of (7), (8), and (9) protruding on each surface.

When surface treatment is performed by immersing the dried pin trans body 12 in the container 13 containing the Snpb plating liquid 14, the plating liquid is formed between the gaps 10 between the surfaces of the pin trans 1. 14) is uniformly penetrated.

The pair of pin members while the injection molding to form the holding member 15 made of synthetic resin so that the plurality of the pin member 5 is formed by unfolding the fin trans body 12 whose surface treatment is completed by the plating. (5) is insulated and fixed, and the terminal pin 16 is manufactured by cutting the center and both side guide members 2, 3, and 4 described above using a jig (not shown).

Therefore, in order to plate the pin transformer 1 as in the prior art, the above-described continuous pin transformer 1 is cut to a predetermined length and then individually or extended to take a specially manufactured conveying mechanism (not shown), and the plating solution is formed at a constant speed. The surface-treated plating is carried out by passing the inside of the container 13 so that it does not undergo surface treatment, and soaks the pin-trans body 12 wound as described above in the plating liquid 14 at once and surface-treats for a predetermined time. Not only is the thickness uniform, but also the cutting of the pin transformer 1 itself is not necessary, which prevents warpage and improves work efficiency by simplifying the manufacturing process.

As described above, according to the present invention, a plurality of protrusions are formed at predetermined intervals on the guide portions of the pin transformer, which are arranged long at the same time as the mold of the pin trans body manufactured for use as a connection terminal for electronic parts, and the like, and are wound around the pins. Since each side of the trans body is formed to have a gap in each side by the above-mentioned multiple projections, and the plating solution is uniformly penetrated by the gap, many products can be plated at the same time, so that there is no variation in plating thickness. By simplifying the manufacturing process, productivity can be improved, and automation at the time of component mounting can be achieved.
