Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention has one crimp terminal of the crimp terminal strip for the end of the electric wire.
In connecting and crimping while separating them one by one, at a time before or after the crimping operation in cooperation with the crimping operation or as an independent operation, a wire end identification tool suitable for being attached to the wire end and a continuous band thereof. Regarding

<Prior Art> A method in which a large number of electric wires with conductive terminals attached are collectively attached to one centralized connector (for example, male type), and can be freely connected and disconnected from another similar centralized connector (for example, female type). Although wire connection methods are widely used, in this case, it is common to attach a mark to each wire in order to prevent incorrect connection. In addition, it is often desired to add the above-mentioned mark even when a large number of complicated electric wire ends are connected close to each other.

However, in the past, since labeling is done manually,
This is extremely inefficient in the case of mass-producing concentrated connectors of the same type, which reaches tens of thousands to hundreds of thousands, and in the case of giving identification symbols to a very large number of wire ends.

<Problems to be Solved by the Invention> Therefore, in view of the above situation, the object of the present invention is to use the automatic continuous crimping system for crimp terminals which has already been widely used, or to cooperate with the system. Or, to provide an electric wire end identification tool that can be used in an automatic machine or a highly efficient manual tool that can be operated independently without cooperation, and a continuous band of the electric wire end identification tool in which a large number of these are connected. It is in.

<Means for Solving the Problems> In order to achieve this object, the wire end identification device according to the present invention is a flexible synthetic resin sheet having an area capable of listing a plurality of identification symbols having visible dimensions. Inside, at least one end portion in the axial direction of the electric wire end portion of the mounting target or a portion in the vicinity thereof is embedded and sealed with a plastically deformable metal body, and the synthetic resin in the portion where the metal body is sealed. The width of the sheet in the direction intersecting with the axial direction is formed to have a length width substantially corresponding to the circumference of the electric wire end portion, and the sealed metal body in the portion extends over substantially the entire width. It is characterized by having a continuous shape.

The present invention also includes a configuration in which a tongue piece having a width smaller than the above-mentioned width is extended from the main body portion at either one of the both ends in the axial direction, and the tongue piece is at least the above-mentioned one. Any width may be used as long as the identification mark can be given.

Further, the continuous band according to the present invention is characterized in that a large number of the wire end identification tools having the above-mentioned configuration are continuously formed in the axial direction or the width direction intersecting with the axial direction. When the tongue piece (tail) is extended to the main body portion (head), it may be continuous by a head-to-tail connection method, or only the head portion is continuously provided in the length direction. The tail portion may be provided so as to intermittently project like a comb.

The metal strip of the wire end identification device according to the present invention may be a sheet-like member which is planarly extended over substantially the entire surface of the synthetic resin sheet in which the wire strip is embedded. It may be a wire-like member located near both ends in the direction or a strip (strip) having an appropriate width or the like.

The material of the metal strip may be any metal that is not difficult to plastically deform, and for example, copper, copper alloys such as brass, aluminum or its alloys, and further mild steel can be preferably used. In short, fragile or high hardness iron alloys such as "imono" and "hagane" are unsuitable because plastic deformation is impossible or extremely difficult.

Various types of synthetic resin can be used as the above synthetic resin for sealing metal strips, but in addition to the "glue" of the identification ink, it is also excellent in heat resistance, flexibility, insulation, etc. and is suitable for melt extrusion molding. Suitable thermoplastics such as polypropylene, polyethylene, polyvinyl chloride and the like are preferred.

The thickness of the synthetic resin sheet has a relationship with the wire diameter or thickness of the metal strip, but generally about 1 mm or less is sufficient.

The continuous strip of the wire end identification device of the present invention is one in which a metal strip continuous in the lengthwise direction is sealed, one in which each identification device is discontinuously sealed, and further a U-shaped groove. The single identification tool formed on the side wall may be temporarily attached to its adjacent side walls.

<Operation> The wire end identification device of the present invention configured as described above is
In the case of the one provided with the above-mentioned tongue piece, the metal strip which is plastically deformable is sealed in the flexible synthetic resin in the vicinity of both ends of the main body portion in the case of the one without the tongue piece. If a bending pressing force in the wire end surrounding direction is applied while being attached to the wire end, it will be deformed into a shape surrounding the wire end, and the deformed shape will be retained even after releasing the upper pressing force. .

It is convenient to perform the imprinting or engraving of the identification mark in the flat state before the deformation, but it may be performed after the deformation depending on the imprinting mechanism.

In order to attach the identification tool according to the present invention to a large number of wire ends in succession, for example, according to the applicant's earlier application, Japanese Utility Model Publication No. 60-
It is preferable to link with the conventionally known crimping machines described in Japanese Patent Publication No. 19344 and Japanese Utility Model Publication No. 60-19345.

When supplying the identification tool as a continuous band, it is necessary to cut and separate the identification tools one by one before the attachment. Also,
It is also possible to adopt a system in which a large number of pre-separated single identification tools are stacked one on top of the other, stored in a cartridge, and then taken out one by one from below. Of course, it is also possible to adopt a method of attaching to the end of the electric wire with a highly efficient automatic or manual tool as a completely separate process without linking with the crimping machine.

In the identification tool of the type having a tongue piece, the tongue piece occupies a position distant from the conductive terminal, and the main body portion is installed so as to occupy a position close to the terminal. It is preferable in the case of simultaneous pressure bonding.

As a marking machine for giving an identification symbol such as alphanumeric characters to the outer surface of the wire end identification device of the present invention, a type of printing using printing ink or a type of engraving with heating type is suitable. Stuff available.

<Embodiment> Each embodiment of the present invention will be described below with reference to the drawings.

In the first embodiment of the present invention shown in FIGS. 1 to 3, a metal strip made of brass, which is similar in shape to the polypropylene sheet (12) and has a slightly smaller size, is formed inside the substantially rectangular polypropylene sheet (12). 14) is sealed as shown in Fig. 3. This wire end identification tool (10)
As shown in FIGS. 1 and 2, the central portion of the wire end portion (W) to be attached is applied to the end portion, and both side portions along the axial direction of the wire end portion are indicated by arrows (Y) and (Y). When bent, the metal strip
The width of the wire (14) in the direction crossing the axis is the wire end (W).
Since it is substantially equal to the circumference, the posture surrounding the end is maintained in a self-sustaining manner.

The identification symbol (S) printed on the surface of the sheet (12) thus displays the number of the electric wire, and is used as a means for preventing erroneous operation in the electrical connection work of many electric wire end portions. Since the sheet (14a) has a matte surface as a rough surface, it is difficult to cause relative sliding between the sheet and the insulating coating on the end of the wire.Therefore, the identification symbol (S) may be displaced toward the back side of the end of the wire. Few.

The crimping attachment of the conductive metal terminal (T) to the electric wire end (W) may be performed simultaneously with or before or after the identification tool (10) is attached.

In the example of FIG. 4, the above-mentioned wire end identification device (10) is a continuous strip integrally formed in parallel with a plurality of long sides thereof joined together, and two adjacent identification devices (10) are provided. Between (10),
In the region where the metal strip (14) does not exist, cuts (16) and (16) are formed on both side edges of the strip so as to face each other. These notches (16) ensure the feeding operation by engaging and disengaging the teeth of a feeding means such as a sprocket wheel when feeding the continuous band to a cutter or the like, and also a pair of facing notches ( 16), the imaginary line connecting (16) is the planned cutting line (C), which acts as a mark when the cutting blade is applied at a predetermined position.
It is also (C).

The embodiment shown in FIG. 5 has a rectangular wire end identification tool (10).
Is a continuous band in which a large number of the identifying tools are formed endlessly in a state where the short sides are joined together, and is the same as the example of FIG. 4 except that the joining direction is different.

In the embodiment shown in FIG. 6, the above-mentioned notch (16) is omitted, and a sheet-shaped aluminum plate which is easy to cut as a metal strip (14) is sealed in a polyethylene sheet (12). It is the body. It is possible to make a large number of wire end identification devices (10), (10) by sequentially cutting at the planned cutting line (C). In this case, unlike the above examples, the cut end face of the metal strip (14) is exposed, so that the metal conductive terminal (T) (Fig. 2) and the strip are attached to the end of the wire. Care must be taken to prevent contact with the end surface of the belt (14). However, the continuous zone of this example has an advantage that it can be easily melt-extruded.

The difference between the example of FIG. 7 and that of FIG. 6 is that the extruded width, that is, the width of the continuous band is increased so that the identification mark can be printed in that direction. There is no risk of contact between (T) and the end surface of the metal strip (14).

The difference between the example of FIG. 8 and that of FIG. 7 is that one aluminum wire is sealed in parallel to both side edges of the continuous strip to make extrusion molding easier. Also in this case, as in all of the above examples, the width of the synthetic resin, for example, the polycarbonate sheet (12) having good heat resistance in this example, in at least a part in the axial direction of the wire end is the circumference of the wire end (W). A metal strip (1
Since 4) also extends over the entire width, the posture in which the wires are cut one by one as shown by the arrow (X) and surrounded by the wire ends as shown by the arrows (Y), (Y) is the ninth position. As shown in the figure, this posture is also maintained independently.

In the embodiment shown in FIG. 10, a pair of aluminum wires, which are slightly shorter than the width of the continuous band, are sealed at a constant pitch, and cut by the line connecting the cuts (16) and (16), and the axis (A) is Since the wire is wound around the wire end in the direction shown in the figure as described above, the identification symbol (S) is in a posture along the circumferential direction of the wire end.

The embodiment of FIG. 11 is a continuous band in which a large number of wire end portion identification tools (10), (10) already formed in a U-shaped groove are temporarily attached to their adjacent side faces to facilitate separation. After separation, it has an advantage that it can be easily deformed when attached to the wire end (W) as shown by the arrow (Y) in FIG. The synthetic resin sheet (1
The surface (12a) of 2) has a satin finish for the reason explained in FIG.

In the example of FIG. 13, the tongue piece (tail) (10a) is extended from the main body part (head) (10a), and a large number of wire identification tools (10) are integrally connected by head-to-tail coupling. It is a continuous belt. 1
The width of the body part (10a) that sealed the pair of aluminum wires (14) (Fig. 14) is equivalent to the circumferential length of the wire end (W), but similarly sealed the pair of wires. (Fig. 14) The width of the tongue piece (10b) is about 1/2 of the circumference length, and the identification symbol (S) is printed on both parts (10a) and (10b). The lock (FIG. 15) is carried out by the main body part (10a).

In the embodiment shown in FIG. 16, a sheet-shaped metal strip (14) is sealed, and a head-to-head connection and a tail are formed by a continuous body portion (1
Although it differs from that of FIG. 13 in that it protrudes like a comb from 0a), it is cut off at the planned cutting line (C) and used in the same manner.

In the case of FIG. 17, the wire in the embodiment of FIG. 8 is changed to a strip (strip), whereby the sealing strength of the metal strip is improved and the planned cutting line (C )
Not only is it easy to cut off, but its thickness can be reduced,
There is an advantage that winding work around the end of the wire is easier and more reliable.

The embodiment shown in FIG. 18 is also a system in which two adjacent wires in the structure shown in FIG. 10 are changed into a single strip and the strip is separated by a line (C) which cuts the strip longitudinally. It is similar to that in the figure.

The embodiment shown in FIG. 19 is a modification of the structure shown in FIG. 6, in which a sawtooth-shaped uneven strip (12b) is formed on the surface of the synthetic resin sheet on the side in contact with the coating (H) of the electric wire (D). Since it is formed so as to be along the axial direction of the end (W), the bending at the time of mounting is the second
It has the advantage of being easy as shown in FIG.

Various modifications can be made to the above-described embodiment of the present invention, for example, a modification in which the shape of each wire end identification device is an "E" shape and the wire is wound around the upper and lower sides of the shape. .

<Effect of the Invention> Since the wire end identification device of the present invention is configured to be attached to the end of the wire by the plastic deformation of the metal strip, the sleeve part into which the end is inserted is not required, and not only is it easy to manufacture. ,
The flat shape before use has not only the operation of printing or engraving the identification symbol but also the general feature of facilitating the handling by the automatic mounting machine.

Further, in addition to the above-mentioned advantages of the individual identifying tool, the continuous strip of the wire end identifying tool of the present invention has a melt extrusion molding particularly in the configurations of FIGS. 6 to 8, 17 and 19. It also has the advantage of being easy to feed into an automatic mounting machine.
