Abstract

PURPOSE:To provide a connector terminal manufacturing method by which the terminal density is heightened, the process is simplified, and the production yield is improved. CONSTITUTION:Three terminal parts 2, 3, 4 in which a plurality of terminals are set in 3-pitch distance are provided and also a fixing part 5 to overlap and fix the three terminal parts 2, 3, 4 unitedly is provided and each of the terminal parts 2, 3, 4 are layered while they are shifted so as not to overlap each terminal 8, 9, 10 of each terminal part 2, 3, 4. Consequently, the first terminal part is shifted by 1 pitch from the second terminal part and the second terminal part is shifted by 1 pitch from the third terminal part and thus the terminal 8 of the terminal part 2, the terminal 9 of the terminal part 3, and the terminal 10 of the terminal part 4 are set successively and the distance between respective terminals is made narrow.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a connector terminal, and more particularly to a method of manufacturing a connector terminal in which a large number of terminals are provided at high density.

[0002]

2. Description of the Related Art For example, electronic devices such as a magnetic disk driving device in which a circular magnetic disk is inserted and a signal is read and written by a magnetic head are required to be small and lightweight. The size of each component is also required to be small. The connector among the components is formed by pressing a multiple-type terminal member into a holder and integrating them.

The connector terminals are, for example, as shown in FIG. 8, terminals 13, 13, ...
4 …… Sliding and punching out the terminals 13 on one side,
.. are bent to form terminals 14 on the other side. As a result, a connector terminal having double the density can be obtained.

In another conventional example, multiple terminal members are formed on a plurality of hoop materials, and terminals are inserted into the holder by shifting the number of hoop materials.

[0005]

However, since the former is formed by bending, the maximum density is limited to double the maximum density.

Further, in the latter case, since a plurality of terminal members made of hoop material are sequentially inserted into the case, the insertion process becomes long and the alignment between the insertion processes is difficult, resulting in poor product yield.

The present invention has been made in view of the problems of the prior art described above, and has been made in order to solve the problems. An object of the present invention is to provide a connector capable of increasing the density of terminals, simplifying the process, and improving the yield. It is to provide a method of manufacturing a terminal.

[0008]

In order to achieve the above object, the present invention provides N terminal members having a plurality of terminals provided at N pitch intervals and claw portions provided at 1 / N pitch intervals. A fastening member, the terminal of the terminal member is fitted between the claw portions of the fastening member, the terminal of the other terminal member is fitted between the other claw portions, and the N terminal members are displaced to form N. The individual terminal members are overlapped with each other, and the claw portions of the fastening member are bent and integrally fixed.

[0009]

With the above means, for example, terminals are provided on, for example, three terminal members at every three pitches, these terminal members are superposed, and at the same time, the second terminal member is placed at one pitch with respect to the first terminal member. The third terminal is displaced by one pitch with respect to the second terminal member. Therefore, the terminals of the terminal members are densely arranged by one pitch.

Is.

In these figures, 1 is a connector terminal, and this connector terminal 1 is composed of three terminal members 2, 3, 4
And a fastening member 5 for superimposing these three terminal members 2, 3, 4 and fixing them integrally.

The fastening member 5 is formed by punching out a long plate material, and as shown in FIG. 6, a large number of bent claw pieces 6, 6 ... When using a single terminal member, 1 for the terminal pitch of the terminal member
/ N pitch. ) Is provided. The bent claw pieces 6, 6 ... Are bent at substantially right angles at their bases, and are formed in a U-shaped cross section as shown in FIGS. 5 (a) and 5 (b).

The terminal member 2 (3, 4) is made of a hoop material, and as shown in FIG. 2, a plurality of terminals 8, 8 ... Are provided at equal intervals from the substrate portion 7. The distance between these terminals 8, 8 is three terminal members 2, as in this embodiment.
When using 3, 4, the bent claw pieces 6, 6 of the fastening member 5
3 times 1 pitch.

Accordingly, the three terminal members 2, 3 and 4 are fitted in the bent claw pieces 6 and 6 of the fastening member 5 of FIG. One terminal 9 of the terminal member 3 and one terminal 10 of the terminal member 4 are arranged at intervals of 1 pitch between the eight. Then, the bent claw pieces 6, 6 ... Protruding from the superposed terminal members 2, 3, 4 are bent inward,
As shown in FIG. 4, the three terminal members 2, 3, 4 are integrally fixed. Thereafter, as shown in FIG. 1, a positioning hole 11 is formed by penetrating the fastening member 5 and the substrate portion 7 of each of the terminal members 2, 3, 4 to obtain the connector terminal 1.

That is, when the three terminal members 2, 3 and 4 are piled up in this state, the terminals are arranged in the order of the terminal 8, the terminal 9, the terminal 10, the terminal 8 and the terminal 9 by one pitch. It is possible to increase the density of the terminals by shortening the distance between the terminals.

Further, since the three terminal members 2, 3 and 4 are integrated, it is not necessary to repeat the insertion process many times as in the conventional case, the process can be simplified, and the process can be simplified. There is no need for alignment, and product yield can be improved.

In the above embodiment, the case where three terminal members are used has been described. However, the present invention is not limited to this, and a plurality (N) of terminal members are used, and the number of terminal members is adjusted according to the number. The distance between the terminals of the terminal member may be N pitch.

As described above, according to the present invention,
N terminal members provided with a plurality of terminals at N pitch intervals,
A fastening member having claw portions provided at a 1 / N pitch interval, the terminal of the terminal member is fitted between the claw portions of the fastening member, and the terminal of the other terminal member is then inserted between the other claw portions. Fitting, shifting the N terminal members, superimposing the N terminal members, and bending the claw portions of the fastening member to integrally fix the terminals, the terminal density can be increased and the process can be simplified.
It is possible to provide a method of manufacturing a connector terminal that improves the yield.
