Description

[Detailed Description of the Invention] The present invention relates to a right angle type connector terminal insertion machine.

A multi-connector in which a large number of small holes are formed at equal intervals in a base made of a molded insulator, and terminals made of a conductor are inserted into the small holes is shown in the front view a and the side shown in FIG. As shown in the cross-sectional view, there is a right-angle type in which the terminal is bent at 90 degrees.

However, 1 in the figure indicates a base body, and 2 and 3 indicate terminals.

The terminal 2 (or 3) used in such a connector is produced by pressing and bending a long hoop material, as shown in the plan view a, front view b, and side view C of Fig. 2. Then, it is connected to the connecting member 4, subjected to appropriate surface treatment, cut to the required length, inserted and fixed into the small hole of the base 1 (Fig. 1), and then the constricted part 5 is formed to weaken the mechanical strength. By cutting, independent terminals 2 (or 3) are obtained.

Therefore, the connecting terminals before being inserted into the base body 1 are subjected to external forces during the surface treatment process after press working, transportation, and storage, and are often bent from the constricted portion 5 and the terminal alignment is disturbed.

In FIG. 2, the terminal 2' is bent with its horizontal portion 2a inclined laterally, the terminal 1 is bent with its hanging portion 2b inclined laterally, and the terminal 2'F is bent. shows the state in which the tip 2c is lifted and bent; in reality, such bending occurs in combination. α shown in Figure 2C is the bending angle of the terminal 2. , normally 90 degrees, but due to variations in the mechanical properties of the hoop materials used, wear of the press die, etc., variations occur within a few degrees between hoop materials. Therefore, conventionally, right angle type The process of inserting the terminals 2 and 3 into the base 1 of the multi-connector has relied on manual labor as the simplest means of dealing with the bending of the terminals.

The purpose of the present invention is to eliminate the above-mentioned manual work and automate it.The purpose of this invention is to provide a pair of connecting terminal guides provided with comb teeth, and to insert the comb teeth of the guide into the connecting terminal from two directions at right angles. It is characterized by comprising means for fitting and disengaging, means for rotating one of the connecting terminal or the connector base by a predetermined angle, and means for inserting the connecting terminal to be fitted with the guide into the base. This is achieved by providing a connector terminal insertion machine.
