(Problem to be Solved by the Invention) The compression mold device according to the above-described configuration can perform compression connection of the branch connection compression sleeve of the flat cable, but the compression is performed because the mold is divided. Each time a connection is made, it is necessary to incorporate each divided piece into the holder, which requires considerable setup time.

The present invention has been made based on the above circumstances, and it is an object of the present invention to provide a compression mold device capable of making a compression connection of a branch connection portion of a flat cable and further minimizing a setup time. The purpose is.

[Means for Solving the Problems] The present invention provides a compression sleeve which is mounted on an exposed conductor of a flat cable and has a connection terminal protruding on one side along the width direction of the flat cable. A compression mold device for compressively connecting the exposed conductor to the exposed conductor, wherein the flat cable is passed between the side walls, and the connection terminal is escaped to one side wall. A holder having a recess of
A lower side on which the compression sleeve is placed while being positioned in the holder; and a first side having a recess positioned along the other side wall in the holder and into which the other side of the compression sleeve is engaged. A mold and a second side having a recess positioned along one side wall in the holder and vertically divided into two parts to sandwich the connection terminal from above and below, and into which one side of the compression sleeve is engaged. A mold, and an upper mold pressed against the upper surface of the compression sleeve, wherein the upper mold and the second armature are formed integrally with the holder including the lower mold or the first armature. Is characterized in that the upper divided piece is integrally formed.

[Action]

The first side mold and the second side mold are fixedly held in the holder by engaging both sides of the compression sleeve. Further, the second side mold has a two-part configuration in which the connection terminal protruding from the compression sleeve is sandwiched from above and below, and the holder allows the connection terminal to enter into the recess on the side wall of the compression sleeve so as not to obstruct the sleeve compression.

On the other hand, since the holder and the lower mold or these and the first armpit are integrally formed, and the upper divided pieces of the upper mold and the second armature are integrally formed, the arrangement of the compression sleeve, and The mold can be assembled with good workability so as not to hinder the holding of the connection terminal and the securing of the escape.

(Embodiment) FIG. 1 is a cross-sectional view of one embodiment of the present invention, in which the same parts as in FIG. In this figure, a holder 11 (hereinafter A), a lower die 12 (hereinafter B), and a first side die 13
(Hereinafter referred to as "C") is bonded and integrated in their assembled state by, for example, an instant adhesive or the like. Further, the second side mold split piece 14A (hereinafter, E) and the upper mold 15 (hereinafter, F) are bonded and integrated in their assembled state by an instant adhesive or the like as described above. In addition, the second armpit type split piece 14B (hereinafter, D) is not integrated with any part but is separated independently.

If the above configuration is integrated in parentheses, and the relationship between the components is indicated by +, (ABC) +
D + (EF).

The compression connection of the branch portion of the flat cable is performed as follows by the mold device of the present invention having the above configuration. That is, the compression sleeve 31 for branch connection, which is compression-connected to the conductor 30 of the flat cable, is a blade terminal to which the branch conductor is to be connected.
It has 31a. First, the integrated holder of the present invention, the lower die, the first side die, that is, (ABC) is mounted on the lower fixing base of the appropriately configured press device, and then, the divided piece of the second side die
14B, that is, the blade terminal 3 of the sleeve 31 for branch connection of D
Engage with the root of 1a, engage with the positioning guide 17 of the holder A of (ABC), mount on the lower die B and attach to the holder A {(ABC) + D}. At this time, the side edge of the sleeve 31 is engaged with the concave groove 13a of the first side die C.

Further, the split piece 14A (E) of the second side mold 14 and the upper mold 15 (F) integrated with the split piece 14A are arranged from above, and the split piece 14A
(E) is aligned on the segment 14B (D). Thus, the root of the blade terminal 31a can be sandwiched from above and below by the split pieces 14A and 14B via the recesses 14b and 14b. Further, the blade terminal 31a, which protrudes in the horizontal direction in the sandwiched state, enters the recess 11a of the holder 11, so that it does not hinder the compression work.

Accordingly, since the upper die 15 is in contact with the compression sleeve 31, the compression sleeve 31 can be compression-connected to the conductor 30 of the flat cable by operating a press (not shown).

As described above, according to the compression mold apparatus of the present invention, a branch connection of a flat cable can be made. Thus, in the present invention, since the components constituting the mold apparatus are integrated into the maximum number of parts that can be put together due to the function of the mold, assembly of the mold apparatus at the start of the connection work is simplified. Thus, the setup time can be significantly reduced.

The holder 11 and the divided pieces 14A of the lower mold 12 and the second side mold 14
The upper die 15 and the upper die 15 may be integrated, and the first side die 13 and the split piece 14B of the second side die 14 may be formed separately.

[Effects of the Invention] As is clear from the above, since the mold device of the present invention is of a split configuration, it is possible to connect a compression sleeve for branch connection with connection terminals protruding sideways. Further, in the mold apparatus of the present invention, since the parts are integrated in groups, the assembly of the mold apparatus at the start of the connection work is simple, and the setup time is significantly reduced.
