Next, FIG. 4 shows the external appearance of the terminal continuum 40 mounted on the cassette body 3. This terminal continuum 40 is
Each terminal connected to a cord terminal such as a communication line is arranged in a row in the lateral direction, and each terminal has a bifurcated connecting portion 42 and a ring portion 43 provided at the base thereof. And are connected to each other via a connecting edge 44 provided on the outer edge of the bifurcated connecting portion of each terminal. The connection edge 44 is formed with a notch 44a by a cutter member so as to be easily cut and separated. Although various methods can be considered as a method of manufacturing the terminal continuum 40, for example, a forked connection portion 42 is formed by punching a strip-shaped strip plate, and a notch for forming a ring portion 43 is formed. The ring portion 43 may be formed by bending the cut portion of the ring portion 43 by caulking or the like. As another method, each terminal is continuously produced by punching press molding, and thereafter, the outer edges of the connecting portions 42 are continuously connected by spot welding to form the terminal continuum 40. It may be one.

Next, the operation of actually connecting the terminal to the cord terminal by using the cord terminal connecting member having the above-mentioned structure will be described. First, assuming that the terminal continuum 40 is attached to the cassette body 3 in the first lever member 1, FIG.
As shown in FIG.
Attach 1. That is, the covering material covering the cable wire 45 is peeled off by using a nipper or the like to expose the internal cord wire. Therefore, the cord wire is inserted into the ring portion 43 of the forked terminal 41 arranged in the window portion 12 of the first lever member 1. At this time, as shown in FIG. 6, since the ring portion 43 of the bifurcated terminal 41 is located at the same height as the movable base 28, the tip of the cord wire when being inserted into the ring portion 43 causes the movable base 28 to move. Upon hitting, the exposed cord wire is positioned in the ring portion 43.

When the cord wire is inserted into the ring portion 43 and the grip portions 5 and 14 of the first lever member 1 and the second lever member 2 are grasped with a hand and a force is applied, the spring 25 is attached. The second lever member 2 approaches the first lever member 1 by rotating around the pin 24 against the power, and the movable blade 17 and the fixed blade 30 cause the leading edge of the terminal continuum 40 and the adjacent second terminal. The terminal located at is cut and separated. At this time, the movable blade 17 and the fixed blade 30 come into contact with the notch 44a of the connection edge 44 between the most distal terminal and the second terminal, so that they are easily cut and separated.

Further, when the leading edge terminal is separated in this way, the ring portion 43 is crushed by the crush plate 16 with the cord wire inserted. That is, when the second lever member 2 approaches the first lever member 1 against the urging force of the spring 25, the forked terminal 41 is pressed by the crush plate 16 from above. At this time, since the connecting portion 42 is on the movable base 28, it is lowered together with the movable base 28 by pressing the crush plate 16, but the ring portion 43 is fixed by pressing the crush plate 16 on the fixed base 35. It is crushed with the table 35. Therefore, the cord wire inserted in the ring portion 43 is pressure-contacted, and the terminal of the cord wire is joined in a state where the terminal does not fall out. At this time, if too much force is applied to the grips 5, 14, the cord wire may be cut off.
The connecting member 21 serves as a stopper.

After that, when the force applied to the grip portions 5 and 14 is released,
The first lever member 1 and the second lever member 2 are opened by the urging force of the spring 25, and the most distal forked terminal 41 located in the window 12 is pressed against the end of the cable wire 45. Separated and removed. In this way, when the most distal forked terminal 41 located in the window 12 is removed, the terminal continuum 40 pressed by the push-out tool 8 slides and the second forked terminal located in the second position. The terminals are arranged in the window portion 12. Then, the cord wire from which the covering material of the terminal has been peeled off is attached to the bifurcated terminal 41 arranged in the window 12.

As described above, after the bifurcated terminals are attached to the ends of the cable wires one after another and all the terminals attached in the cassette body 3 have been attached, a new terminal continuum is attached as follows. To be done. First, the cassette body 3 is taken out when the terminal continuous body 40 is mounted.
The fixing member 31 is removed from the lever member 1. To remove the fixing member 31, the claws 34 protruding to the outside of both side surfaces are used.
Is pushed inward, and the upright surface 31a of the fixing member 31 is deformed inward, a finger is inserted from the insertion opening 6 and the fixing member 31 is pulled out. Then, the fixing member 31 releases the cassette body 3 fixedly provided in the constituent portion 4 of the first lever member 1 and is taken out from the insertion opening 6.

Then, the terminal continuum 40 is mounted on the cassette body 3 taken out. At this time, as shown in FIG. 5, it is necessary to orient the connecting portion 42 of the bifurcated terminal 41 on the movable base 28 and the ring portion 43 on the fixed base 35. Terminal continuous body 40 to cassette body 3
After mounting the cassette body 3 in the first lever member 1, the cassette body 3 is inserted into the constituent portion 4 through the insertion opening 6 of the first lever member 1. Then, after the cassette body 3 is inserted, the convex portion 32a of the pressing member 32 of the fixing member 31 is inserted into the groove portion 27 of the cassette body 3 and pushed in. Then, the pressing member 32 comes into contact with the terminal continuum 40 in the cassette body 3, but when the fixing member 31 is further pushed in, the spring shaft 33 is compressed and the claw 31 is fitted into the fitting hole 9. At this time, since the pushing member 32 urges the terminal continuous body 40 toward the window portion 12 side of the first lever member 1, the most distal terminal of the terminal continuous body 40 has the component 4 as shown in FIG.
It comes into contact with the locking portion 4a of the above and is positioned in the window portion 12.

Although one embodiment of the cord terminal connector has been described above, the present embodiment has the following effects. The forked terminal 4 is provided in the window 12 of the first lever member 1.
Since 1s are sequentially sent, the troublesome handling of the fine terminals is eliminated. Further, since the bifurcated terminal to be attached is fixed to the window portion 12 of the first lever member 1 at the time of attachment, the cord wire of the cable can be easily inserted. Further, since the bifurcated terminal constitutes a series of terminal continuous bodies, continuous work can be easily performed.

By the way, the cord terminal connector of the present invention is
The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. For example,
In the above-mentioned embodiment, it is a hand-held type, but it may be a hand-held type. In that case, the first lever member is placed on the table, and the second lever member is grasped and pushed down,
The terminal will be coupled to the cord terminal. In the above embodiment, an example of connecting the forked terminals is shown, but it is of course applicable to connection of ring-shaped or hook-shaped terminals, and the point is to connect the terminals to a terminal cord such as a communication line. Anything that binds is included in the present invention.

[0023]

According to the cord terminal connector of the present invention, when the forked terminal is attached to the cable, the terminal continuum connected by the pressing member is moved to the window portion, and at the same time, the terminal member is separated by the cutter member. Since the ring portion formed on the terminal is pressed by a crushing member that crushes, it is possible to provide a cord terminal connector that can simply and quickly connect the terminal to the end of the cable wire in the wiring work,
As a result, the efficiency of cable wiring work was improved and the economic burden was reduced.
