Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention relates to a method of manufacturing contact terminals for electrical connectors used, for example, in electronic equipment.

(b) The blue contact terminal of the invention is made by molding hoop conductive material with the same pitch as the contact terminal holes of the connector housing using a progressive die.
] Pressing a large number of contact terminals in a row in succession using a staggered process with a small amount of scratches to form the first and second row sides of the contact terminals, and then the first row sides a3J and On the second row side, the first and second row sides of the contact terminals were cut into two parts in a continuous state in a vertical row, and a predetermined surface treatment was applied to the contact terminals in a continuous state in the vertical row. Under this condition, an automatic machine is used to automatically assemble the connector into the housing.

However, in the case where partial jet gold plating is not applied to some of the electrical contact parts of the contact terminals using the surface treatment described above, in the conventional TJIJ manufacturing method of the contact terminals of electrical connectors, the separated contact terminals are separately jet gold plated. Must be gold plated2
This required multiple jet gilding processes, which increased costs.

(c) Purpose of the Invention Therefore, the present invention aims to reduce the processing loss of conductive materials by applying jet gold plating T to the contact terminals that have been removed.
The object of the present invention is to provide a method for manufacturing contact terminals of electrical connectors that streamlines the culm and reduces the cost of jet gilding.

(d) Summary of the Invention This light uses a hoop formed on both sides of the frosted moon.
・P/P on each of the rear first row side 63 and second row side
Contact terminals are arranged in a staggered manner by two pitches.
At the same time, if the contact terminals of both rows are overlapped, the contact terminals of one of the two rows are overlapped, and the contact terminals of the electrical connector have a step between them and the carrier so that each contact terminal is located in a flat plate shape. 12. Remove the mold.

(Small) Effect of J and Ming In this invention, J, is the first of Killeria after the end of the presue culm.
When the row side and the second row side are separated into two parts and the carriers are pressed together, the second row side of the contact terminals is placed between the first row side of the contact terminals, and the contact terminals of each row form a flat plate. It becomes like this.

Compared to the conventional method, 218 pieces of jet gold plating can be performed in one process, and the labor cost for jet gold plating is halved, making it possible to reduce costs.

(f) Examples of the invention An embodiment of the present invention will be described in detail below based on the drawings.

The drawing shows a contact terminal manufactured by the manufacturing method of the present invention, and as shown in FIGS. The electrical contact portion 4 and the terminal portion 5 protrude from the upper end surface and the lower end surface respectively, and are irremovably fixed to the aforementioned connector housing 2 by appropriate fixing means.
The aforementioned terminal portion 5 is inserted and fixed into the base plate 1, and the aforementioned electrical contact portion 4 contacts the pressure contact terminal of the movable side connector to form an electric circuit between the printed circuit board and the movable side connector. Lee.

Previous) Small tangent F+1! The terminal 1 is connected to the first row side 63J and the second row side (7-a), (7-b) of the carrier 7 for transfer formed on both sides of the hoop conductive material 6 in the transfer direction. Then, in a staggered pattern with less material loss, connect them vertically with #;, + L, T.
J is connected to the connecting piece 8.

There are also 13 drying racks arranged on the first row side and the second row side.
The row sides (1-a) and (1-b) are as shown in Figure 3.
In the vicinity of the above-mentioned contact piece 8, a vertical step 9 is formed with a plate thickness t.

The small contact terminals 1 (front) are arranged at the same pips [ ] as the contact terminal holes 3 described above, and are located on the first row side (1-
a) and the second row side (1-b) are at the center 4;l ti'
J was shifted by 7 pitches from pitch P to H, and -C was purchased, creating a staggered pattern of 4111 pitches.

First row side J and second row side (7-a) of Kirlia 7 mentioned above
), (7-b) are each drilled with one pilot hole 10, and the aforementioned hoop conductive material 6 is transferred to the pilot hole 10, and the positions are transferred in each step of the progressive die. The same determination is carried out, and the above-mentioned contact terminal 1 is continuously formed from the hoop material of the previous hoop conductive material C.

The pilot hole 10 of
The above-mentioned pitch in the transfer direction from the center position of the row side 63J and the second row sides (1-a) and (1-b)]] Shift the L pitch center point back and forth, and set the center point in the transfer direction. They are arranged in a straight line that intersects 1゛1. Furthermore, the pitch between the center points is the same as the pitch 1] described above.

Next, the jet gold plating process of the contact terminal 1 mentioned above will be explained.

After forming the contact terminal 1 by pressing a large number of hoop conductors (Δ6) successively in a vertical line using a progressive die of a transfer press machine in a well-known manner, The first contact terminal 1 is placed on the sides (7-a) and (7-b).
The first row side (7-a) and the second row side (7-b) of the carrier 7 are divided into two with the row side and the second row side (1-a) and (1-b) connected respectively. Release l/J.

Next, press the back surfaces of the first row side (7-a) and the second row side (7-b) of the cut Kireria 7 together, and at the same time,
When the pylons 1 to holes 8 are aligned, the contact terminals 1 are connected between the first row side (1-a) and the second row side (1-b
) are arranged, and as shown in FIG. 5, the first row side J5, the second row side (1-a), (1
-b) are mutually flat.

Next, the stacked metal parts 7 are held on top 7j by appropriate means, and one or both sides of the plating zone G of the electrical contact part 4 is partially treated with jet gold plating once (discussion).

In the above embodiment, a step 9 is formed 113 on the contact terminals 1 of the phase D- row, and the contact terminals 'i'-1 of one row are
With this in mind, a step S is set (), and the amount of this step can be expressed as the amount by which the contact terminal 1 is flattened when the kits and rears 7 of the i-th row are overlapped.
