Description

[Detailed Description of the Invention] The present invention relates to a ribbon cable splitting device that splits and spreads a ribbon cable according to the pitch of a terminal to be crimped to the tip of the ribbon cable.

In ribbon cables, in accordance with this number of core wires, terminals are crimped to the tips of each wire at the same time to simplify the work process.

That is, to explain this with reference to FIGS. 3 and 4, the terminals T are connected to the carrier C at regular intervals, and the ribbon cable R is
The tips of the terminals are spread out in line with the pitch of the terminals T, and the tips of each wire S are aligned and fixed in a straight line. After the terminal T is attached to the tip of each wire S, crimping and After crimping, the carrier C is removed and each wire S
Terminals T are attached to the ends of the respective terminals.

The ribbon cable R is divided into lines and arranged at predetermined intervals by holding the ribbon cable R between the line separation guide 9 and the wire receiver 3, sliding the separator 5 to separate the lines with the branch teeth 7, and then each wire rod. S to wire insertion path 8
However, in a conventional wire separating device of this type, as shown in FIG. The R branch lines were made almost simultaneously, and the troughs of the wire insertion path 8' were spaced at regular intervals.

However, in this case, since the ribbon cables are separated almost simultaneously, there are disadvantages in that not only does the pushing pressure become large, but the wire S is easily damaged, and the mold shape becomes complicated and expensive. Ta.

In view of the above, the present invention has been devised to provide a device that not only does not require a large indentation pressure but also can prevent the occurrence of scratches on the wire, is relatively simple in shape, and can be manufactured at low cost. The gist of this is that in a wire splitting device that clamps a ribbon cable between a wire clamp and a wire holder and separates it by sliding a separator, the branch teeth protruding from the separator are designed to have a pointed overall shape. A ribbon cable splitting device characterized in that when formed into a shape, a slit-like wire insertion path is provided so that the ribbon cable splitting is performed step by step from the center as the separator slides. It is in.

This will be explained in detail based on the illustrated embodiment. In the figure, reference numeral 1 denotes an electric wire clamp, which is composed of two plates 2, 2 facing each other with a predetermined distance between them.
Recesses 2a, 2a for holding the ribbon cable R are formed at the lower end of this plate.

3 is a wire holder with a U-shaped cross section that opens upward;
This upper end surface and the lower end surface of the plates 2, 2 of the electric wire clamp 1 are brought into contact with each other to sandwich the ribbon cable R in the recesses 2a, 2a, thereby configuring a clamping mechanism 4 that restricts its vertical movement. belongs to.

5 is a rectangular frame-shaped separator, which is connected to the wire receiver 3 above.
The rear edge is fitted into the opening of the wire receptacle 3 and is slidably installed, and the front edge is located in front of the wire receiver 3, and at its upper end there are holes arranged at intervals that match the pitch of the terminal T with the carrier C. A wire support groove 6 is provided.

Further, at the upper end of the rear edge, a branch tooth 7 is provided which is formed into a pointed shape as a whole and has a slit-like wire insertion path 8, and the trough of this wire insertion path 8 extends upward. It has a prominent arc shape.

The branching tooth 7 is for separating the ribbon cable R into each wire S, and by making the whole into a pointed shape and providing a wire insertion path 8, the branching line can be separated into stages. That is, as the separator 5 slides, first a dividing line is made at the center to divide it into two parts, and each of these two divided parts is further divided into two parts at the center side, and this is repeated sequentially to make all the dividing lines. , the split wire S is inserted into the wire insertion path 8, respectively, thereby reducing the pushing pressure during splitting and preventing the occurrence of scratches on the wire.

Moreover, the reason why the trough of the wire insertion path 8 is shaped into an upwardly protruding arc is that the separator 5 is slid so that the trough protrudes from the upper surface of the wire receiver 3, especially in the center, and the wire S is This is to bend the ends of the wire S in a straight line by bending the wire S in a manner that increases toward the center.

Reference numeral 9 denotes a wire segment guide which is slidably interposed between the plates 2, 2 of the wire clamp 1, and has a notch 10 formed so as to surround the branch tooth 7 of the separator 5. This is to guide the wire rods S into the respective wire rod insertion paths 8 on both sides of the branch teeth 7 without difficulty.

In a usage example of the present invention, the tip of the ribbon cable R is inserted between the wire receiver 3 equipped with the separator 5 and the wire clamp 1 with the wire separation guide 9 interposed therebetween.

Then, as shown in FIG. 2, the wire clamp 1 is lowered, the ribbon cable is clamped by the clamping mechanism 4 with the wire receiver 3, and its vertical movement is restricted.
The segment guide 9 is lowered to bring its lower end surface into contact with the upper surface of the separator 5.

In this state, as shown in Figure 3, the separator 5
is lifted together with the wire separating guide 9 until its upper surface coincides with the upper surface of the wire receiver 3, the ribbon cable R is separated into each wire S by the branch teeth 7, and this is inserted into the wire insertion path 8. The ends of the wires are inserted into the wire rods to spread them apart, and the tips are guided into the wire support grooves 6 of the separator 5 to form a constant pitch.

At this time, the branches of the ribbon cable R are spread out step by step as shown in FIG. Therefore, the extrusion pressure can be reduced and the wire rod S can be prevented from being damaged.

Moreover, the wire rods S on the center side are pushed upward by the valleys of the wire insertion path 8 and are subjected to an upwardly convex bending process, and this process becomes larger toward the center, so that the tip of each wire rod S is straight. It will be arranged in a shape.

Then, terminals T connected at regular intervals are supplied to the carrier C, and after these are attached to the tips of each wire S, they are simultaneously crimped using a crimping jig (not shown).
Cut carrier C in the width direction.

Next, as shown in FIG. 4, the wire clamp 1 and the wire segment guide 9 are raised, and the separator 5 is lowered to release the ribbon cable R and take it out.

Thereafter, the carrier C is removed and the terminals T are attached to the ends of the wires S, respectively.

Since the present invention has the above-mentioned configuration, the ribbon cable is separated gradually from the center outward as the separator rises, so there is no need to increase this pushing pressure so much. It is also possible to prevent the occurrence of scratches on the wire.

Moreover, the shape of the branch teeth is relatively simple and can be manufactured at low cost.
