Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a terminal to be attached to the end of an electric wire, and more particularly to a chain terminal suitable for continuous supply to a processing machine for attaching electric wires.

Prior art When attaching a terminal to the end of an electric wire,
Attachment work is carried out continuously using a processing machine for attachment. Terminals supplied to such attachment processing machines are required to have their orientation aligned in a certain direction, and are often supplied to the attachment processing machine in the form of a chain terminal in which a large number of terminals are connected in a fixed orientation.

Such a chain terminal is formed from a metal strip by punching, plating, press molding, etc., but the individual terminals A are not separated, and their front and rear ends are mutually connected, as shown in Fig. 5. It is formed in the form of a vertical chain connected by a connecting member B, or a horizontal chain whose front and rear ends are respectively connected to ribbon-shaped connecting members C and C' as shown in FIG. The chain terminals supplied to the attachment processing machine are then separated by a press, and electric wires are attached to the chain terminals to form a product.

However, when separating the terminal and the connecting member, if the remaining connecting part of the connecting member is too long, the attached electric wire may contact when bent and damage the insulation coating, causing failures such as damage to the connecting part. If the cutting position is too close to the terminal side, electrical contacts and other parts may be deformed, resulting in defective products.

Problems to be Solved The present invention attempts to provide a chained terminal that can accurately detect the terminal separation position, thereby making it easy to adjust the cutting length of the terminal joint. The purpose is to

Means for Solving the Problems The object of the present invention is to provide a terminal chain body in which a connecting member is connected to the front end and the rear end of a terminal in which an electric contact part is provided on an extension of a wire fixing part, respectively.
This is achieved by means of a chain terminal, characterized in that each of the connecting members is provided with a set of cutting target position markings, consisting of two outer limit position markings and two inner limit position markings.

Embodiment FIG. 1 shows an example of the chain terminal of the present invention.
In this example, a vertical chain is used, and the terminals A are connected to each other by the connecting member 1 in a head-to-tail connection state. A marking line 2 is provided on the surface of the connecting member 1, which is stamped at the same time as the terminal is press-molded. In this case, four marking lines 2 are provided in parallel, the outer two being outer limit lines 2a and 2d, and the inner two being inner limit lines 2b and 2c.

The chain terminal thus formed is separated by separating the connecting member 1 and cutting it off in line with the position of the die 3. At this time, the separation lines 3a and 3b on both sides of the die 3 are aligned with the outer limit line 2a, respectively. , 2d and the inner limit lines 2b, 2c, the lengths of the remaining connecting portions 1a and 1b of the connecting member 1 will be correctly within the tolerance range (FIG. 2).

Figures 3 and 4 show the state in which the correctly separated terminal A is caulked and fixed to the electric wire D, and the remaining connecting parts 1a and 1b of the connecting member
The length is appropriate and there is no problem in bending the electric wire D.

In this example, the cutting target position marking provided on the connecting member is obtained by stamping, but it may be provided by other methods such as printing or plating, and the shape is not limited to linear. It may be a marking mark in the form of a band or other appropriate form. Moreover, such an indicator mark may be provided on either the front side or the back side of the connecting member, or may be provided on both sides.

Function: Since the chain terminal of the present invention has cutting target position markings on the connected connecting members, it is possible to easily and reliably align tools etc. during cutting.

Effects of the invention When a terminal is correctly cut from the chain terminal of this invention, the remaining length of the connecting part of the connecting member is not too long, and therefore there is no risk of failure even if the attached electric wire is bent. . In addition, defective products are less likely to be produced due to mistakes in cutting too short. Further, in product inspection, since the cutting reference position is clear, there is an advantage that judgment can be easily made by visual inspection.
