Abstract

PURPOSE:To provide an installation terminal belt-like body in which installation terminal members are held in a line by connection members so as to supply them stably at a high speed by drawing cylindrical parts in the belt-like body, and forming pilot holes and punched parts in it. CONSTITUTION:A belt-like body 10 is sent to a press work machine or the like, where cylindrical parts 11 are formed by drawing work. At completion of the drawing work, pilot holes 12 are bored, and punched parts 13 are formed at middle positions between the adjacent cylindrical parts 11. An installation terminal belt-like body X in which installation terminal members 5 are connected by connection members 14 along the length and width to be held in a line can thus be provided. Deflection of the position or deformation of the attitude of the members 5 can thus be eliminated, thereby the members 5 can be stably supplied to an automatic machine such as a robot.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting terminal strip, a method of manufacturing the same, and a method of mounting an electronic circuit terminal.

[0002]

2. Description of the Related Art When terminals are arranged on an electronic circuit board such as a printed circuit board, the technique shown in FIG. 4 is often used.

A terminal hole 2 is formed in the edge of the circuit board 1,
Through hole plating or solder plating 3 in the terminal hole 2
And connecting to the circuit conductors 4 on one side or both sides. When connecting a lead wire or the like, a method of inserting it into the terminal hole 2 and fixing it by soldering or the like is adopted. A terminal (mounting terminal member) 5 as shown in FIG. 5 is inserted into the terminal hole 2, and the diameter and the caulking are performed as indicated by an arrow and a chain line so that the circuit conductor 4 is connected to the circuit board. 1
How to fix to. When connecting a pin hole or a lead wire to the terminal hole 2, a method of inserting them and connecting them by contact or soldering is adopted. The tubular portion 7 of the mounting terminal member 6 as shown in FIG. 6 is inserted into the terminal hole 2, and the diameter is expanded and the caulking is performed as shown by the chain line so that the circuit board 1 is connected to the circuit conductor 4. How to fix to. When connecting pins or lead wires, a method is used in which these are inserted into the connection holes 8 of the mounting terminal member 5 and connected by contact or soldering.

Comparing these techniques, the method of mounting the mounting terminal members 5 and 6 by caulking is easier than the method of plating the through hole and the like by the robot and the mounting terminal can be easily automated. The fixing strength of the member 5 can be increased.

When the mounting terminal member 5 is automatically mounted on the circuit board 1 by a robot or the like, the mounting terminal member 5 is aligned by a parts feeder or the like as shown in FIG. 7 and moved in the direction of the arrow. One of the most effective methods is to grab up with and automatically assemble.

[0006]

However, the mounting terminal members 5 in the aligned state as shown in FIG. 7 tend to lose their posture due to external force such as vibration. There is a point to be solved that the sex is significantly impaired.

The present invention has been made in view of these circumstances, and it is an object of the present invention to prevent the positional displacement of the mounting terminal member and the collapse of the posture thereof and to supply the mounting terminal member at a high speed in a stable state.

[0008]

The present invention proposes the following in order to solve the above problems. The first means is
This is a strip-shaped mounting terminal, and a plurality of pilot holes (12) are arranged in the strip (10) at intervals in the longitudinal direction.
Mounting terminal members (5, 6) having tubular portions (11, 21) formed by drawing at a set position separated from the pilot hole
And the mounting terminal member has a plurality of connecting pieces (14, 2).
Except for the portion 3), the cutout portions (13, 22) separate the strip plate. The second means relates to a method for manufacturing a band-shaped body of mounting terminals, which includes pilot holes (12) in a state of being longitudinally spaced from the band-shaped body (10) and tubular portions (11, 21) by drawing. And a step of forming a plurality of connecting pieces (1
Cutout mounting terminal members (5,
6) is adopted. A third means relates to a method of mounting an electronic circuit board terminal, and includes a step of moving the mounting terminal strip (X, Y) in the longitudinal direction to detect the pilot hole (12) and stop the mounting, and a mounting terminal. The step of separating the mounting terminal members (5, 6) mounted on the strip from the connecting pieces (14, 23), and the tubular portions (11, 2) of the separated mounting terminal members.
1) is inserted into the terminal hole (2) of the circuit board (1) and the cylindrical portion is expanded and crimped.

[0009]

In the first to third means, the position of the subsequent process is set by the pilot holes arranged in the strip-shaped plate, and the strip-shaped plate is partially extruded in the thickness direction. To form a tubular portion. When an uneven thickness portion or a streak is generated around the cylindrical portion due to material movement during drawing, the cutout portion is formed to separate the attachment terminal member. The mounting terminal strip in which a plurality of mounting terminal members are mounted is managed in the form of a strip or a roll, and the mounting terminal members are supplied while being aligned by the movement in the longitudinal direction. At the time of supplying the mounting terminal member, the position of the mounting terminal member is set by detecting the pilot hole, and the mounting terminal member is supplied to the circuit board by separating it from the connecting piece, and the tubular portion is connected to the terminal of the circuit board. The mounting terminal member is fixed to the circuit board by inserting into the hole and expanding and caulking the tip of the tubular portion.
