Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric wire formed by forming a military path for conducting current on at least a portion of the fastening surface itself of a band-like or sheet-like EE peelable fastener, particularly on the corrugated strips thereof. and its manufacturing method.

In general, the internal wiring of various electronic and electrical devices and the electrical equipment of various types of vehicles involve a large number of intertwined wires, and the work of bundling each wire into bundles is quite a tedious task.

For the attachment, a special binding odor was prepared inside the chassis or body, but the cost and effort of fixing this binding odor in advance was not prohibitive, and of course, the design of the binding tool itself,
Production was also an extra effort. Particularly in computer terminal equipment, etc., flat wires made of multiple pongee wires lined up horizontally are commonly used, but since these wires are quite wide, when you try to fasten them, the binding smell itself is quite bad. It was large, and the situation was extremely disadvantageous in terms of space factors.

The present invention has been made in view of the above, and provides an electric wire in which a crimp is formed on at least a part of the attachment surface itself of a crimp-peelable fastener that does not distinguish between male and female, and in order to fasten this electric wire. , all you have to do is stick an appropriate length of a crimp-peel type fastener with the same fastening surface configuration as that used for the above-mentioned electric wire to the part where you want to fasten it, making installation and fixing more convenient. Due to its nature, it can be cut freely, the length can be set freely, and it can be made thin, so it can be used in any mounting location, and the space factor has also been significantly improved. It is something.

Therefore, according to the present invention, it can be said that the electric wire itself constitutes the crimp-peel type fastener, and it can also be said that the crimp-peel type fastener itself has an electric path. It is possible to configure the electric wire with the anchoring surface to have substantially the same minimum dimensions.

Moreover, if necessary, if at least a portion of the length of the tortoise path is left bare, both the locking surfaces can be connected at the same time by simply physically engaging or joining the locking surfaces of the turtles formed in the same way. Since the electric lines provided on the surface can be electrically connected to each other, electric lines can be branched or integrated without the need for a separate connector.

The crimp-peel fastener that can be used in the present invention has crests and recesses arranged continuously and alternately in the length direction to form a single wavy strip, and this wavy strip is arranged in a direction perpendicular to the length direction. multiple,
It is sufficient that they are arranged side by side to form a band-like structure as a whole, and that the peaks and recesses of adjacent corrugated stripes are shifted in a predetermined phase relationship.

The most basic type of pressure-peel fastener is disclosed in Japanese Patent Publication No. 49-37967, as shown in Figures 1A to 1C of the drawings attached to this book. , the concave portions 2 that are continuous with respect to the peak portions 1 of each waveform strip a form valley portions having the same shape as the peak portions turned upside down.

Adjacent wavy strips are indicated by a and a', respectively, and as can be seen from the perspective in Figure 1B, these adjacent wavy strips are
There is a certain phase difference between the peaks and troughs of the other, and in the case shown, the peak of one wavy strip is at the peak of the trough of the other waveform. There is. When two such fasteners A are used and they are crimped together, as shown in FIG. It is filled with iron, and together with the frictional force between the adjacent corrugated stripes a and the green on the side a, they come to engage with each other.

This fastener can also be engaged to maintain the loop by drawing a loop and then overlapping both ends of the loop as shown in Figure 1C; In addition to being able to bundle electrical wires and cables, it is the first
As seen in fastener A' stacked from above in Figure C, when viewed from the back of a single fastener, the ridges and recesses are reversed and become recesses and ridges, respectively, so it is difficult to stack many fasteners together. You can also go.

However, since these points have no direct relation to the present invention, further explanation will be omitted. In contrast to this basic shape, there are cases where the recess 2 is located between the peaks 1 and has an acute angle shape, as shown in the second figure, and a recess 2 as shown in the third figure.
has a flat shape (Hakama Seki Sho 47-224 Bulletin), and as shown in Figure 4, a laminate layer 3 is applied to cover the back side of this flat part to increase physical strength ( (Japanese Patent Publication No. 52-44251), etc., go further and attach an adhesive layer to the back surface 3, or as shown in Figure 5, install an anchor-type or canoe-type mounting fastener 4 in the gutter to attach the mounting body. There are also products that can be attached to P with one touch. FIG. 5 is a cross-sectional view of the fastener A viewed in the longitudinal direction, and for only the fastener A, it is a cross section taken along the line V-V in FIG. 1A.・In addition to the above-mentioned various modifications, as disclosed in Japanese Patent Publication No. 52-44249, a projection 4 protruding in the machine direction is provided at the apex of the valley part, and this is used as a locking pawl to increase the anchoring force. , from the same point of view, disclosed in Japanese Patent Publication No. 52-4425, in which a locking pawl is provided that extends laterally on the sloped portion from the peak to the concave portion, with the phase difference between adjacent waveform strips being suppressed slightly. Something like this has also been developed.

Embodiments of the electric wire of the present invention and its manufacturing method using such existing crimp-peel fasteners are shown in FIGS. 6 and subsequent figures.

In the embodiment shown in FIG. 6, the press-release type fastener A shown in FIG. 3 or FIG.
K of the corrugated strips a consisting of flat portions 2 alternately continuous in the length direction, grooves C'' made of thin bare conductors such as steel strips on the surface of the concave portions (flat portions), It is assumed that it will be pasted.

In the above, when we consider the three lotus waveforms a1, a2, and a3 in Figure 6A, the middle waveform a2 is skipped and the strips are applied to the waveforms al, a3 on both sides. Of course, this is to prevent short circuits between adjacent wavy lines.In other words, the wavy lines c'' are pasted on each of the plurality of wavy lines on which the wavy lines are attached. Moreover, it is possible to form current lines and signal lines that are separate and independent from each other.

However, on the contrary, when the entire surface of one crimp-peelable fastener A functions as a single crab track, it is not necessary to limit the number of strips to every other strip, and furthermore, in order to reduce the line resistance, the surface of all the corrugated strips should be The above-mentioned strip-like electric circuit configuration may be applied to the circuit. FIG. 6B is an enlarged view of one waveform strip a to which the electric circuit c'' has been attached in this way, and the end portion of the wire is intentionally turned up. Various existing techniques can be used to attach the curved path c'' by following the uneven shape formed by the peaks 1 and the recesses 2 of the corrugated stripes a, for example. There are methods such as using plastic deformation of the strip-shaped member used as the electric circuit and gradually adhering it with an appropriate adhesive.
Of course, such a method may be used, but one desirable attachment method is the manufacturing method as the second aspect of the present invention, as described below.

This type of crimp-peel fastener is already disclosed in the official gazette No. 4424 of 1983 and the official gazette of 4425 of 1987, so the details will be omitted. An embodiment of the manufacturing method of the present invention will be explained based on the premise that the process starts after the formation of the fastener geometric shape by such diamond straightening. First, as shown in FIG. The fastener A, which has been formed, is advanced in the direction of the arrow shown in the figure and placed between at least a pair of opposing haze road application rollers 11a and 11b.

In this case, it is assumed that the fastener is as shown in FIG. 6, and is flowing with the peak 1 facing upward in the drawing. Upper roller 1
Reference numeral 1a is a roller having a configuration that does not damage the shapes of the ridges and recesses (flat parts) of the molded fastener. That is, this loaf may have the same configuration as the forming roller in the molding machine seen in the above publication, and to put it simply, the loaf has an annular tooth row contour with a complementary shape to the peaks and recesses of the corrugated strip a of the fastener A. It is said that the thickness is the same as the width of a single wavy strip, and that multiple wavy strips are arranged in parallel so that the tooth rows of adjacent ones have the same phase difference as the phase difference between adjacent wavy strips of the fastener. It is made up of Between this pair of rollers,
One or more military strips c'' such as copper foil strips sent out from a separate feeding mechanism are aligned and wound around the corrugated strips a to be attached.

Prior to this, a suitable hot melt agent or the like is applied to this strip by a known method, and roller pairs 11a, 1 are applied.
It is preferable to heat it with an appropriate heating source 12 immediately before rolling it between the layers 1b.

According to the above process, Huasuna A! When passing through the Zenigata roller la, each strip or electromagnetic c'' is plastically deformed to conform to the shape of the corresponding fastener corrugated strip a, thereby physically crimping or, as described above, If hot-melt agent application and heating steps are included, each corresponding corrugated strip a can be melted and bonded more reliably.

The electric wire with the fastening surface 7 formed in this way has the same shape and thickness as the conventional peel-off type fastener, and does not become unnecessarily thick or lose its appearance. .

Therefore, when using this electric wire for routing wiring inside a car or various electronic or electrical equipment, special binding tools are not required to secure it so that it does not dangle as necessary.
Attach a crimp-peel fastener that has the same shape as the attaching surface of the crimp-peel fastener A, which is the basic member of the electric wire, to the part to be fastened, and cut it to an appropriate length. It is convenient for maintenance and inspection because it is easy to remove and remove.

In particular, it has excellent space fixity, and is ideal for internal wiring of electronic computers, etc., which generally use flat wires with many core wires arranged side by side. You are free to increase or decrease it depending on your needs.

Additionally, the flexibility required for routing can be fully explored. Another great advantage is that, as shown in FIG. 8, if you prepare another electric wire of the present invention using a similar fastener A', you can physically crimp and fix the two, and the exposed circuit between the two can be fixed. It is also possible to make an electrical connection between the two directions. This means that, for example, in FIG. 8, the groove from the x direction can be reversibly branched to the x, x2 directions.

In addition, in the above description, in order to prevent lateral short circuits between exposed circuits on different waveform strips a, it is sufficient to attach a mist circuit to every other strip, for example, but if the width of each electrical circuit c'' is As long as the width is narrower than the width of each corresponding corrugated strip a on which the wavy strips a are placed, it is not necessarily necessary to have every other strip, and on the other hand, when spacing is provided, it is of course possible to use every second strip, every third strip, etc.

Also, as mentioned earlier, if a single line t is sufficient, in the forming method shown in Fig. 7, the haze path c'' is made into a sheet shape such as a thin plate of copper foil, and the corrugated strip group and complementary shape are formed. The grooves may be completely attached to all the corrugated stripes of the fastener, as if slightly press-molded, by the shaping roller la.

On the other hand, when it is formed into multiple lines, it is most suitable for use in the above-mentioned electronic computer.

This is because although a large number of lines are required, the current per each line is generally small. In such a case, the terminals of the outlines on each waveform strip may be soldered to the red wires to be connected, but usually they are used to process multi-line core wires lined up in a straight line. You may use the connector with some modifications. In addition, as shown in Figure 8, in order to find continuity between two electric wires, it is necessary to position the corrugated stripes that are connected to each other and then press and engage them. In order to do this, if you place marks on the fastener parts of both, or if you regularize the wavy strips in advance that have the same width and provide a lightning path, you can crimp them together by matching the marks or matching the width. The desired crimping and connection between electrical circuits can be ensured by simply using the following method.

In the above embodiment, the pressure release type fastener A in which the concave portion 2 is a flat portion is used as the starting member, but of course, the fastener A shown in FIG. 1 and FIG. It is possible to use one appropriately selected from the following.

In particular, when a fastener with peaks and valleys on both sides is used as shown in Figures 1 and 2, the lower roller 11 in Figure 7 is
b may also be provided with a complementary tooth structure that does not disturb the peaks and valleys.

Furthermore, using the same logic as that of attaching the electric circuit c'' to one side in FIG. 7, it is also possible to make an electric wire having electric circuits c'' and c'' on both sides of a fastener shape, as shown in FIG.

In this way, in addition to the main blade flow path extending from the x direction to the X2 direction, reversible branch lines X, , x3 can be provided from both sides.

In addition, when designing by predetermining branch points in Figures 8 and 9, even if the tortoise route is not exposed over its entire length, it may be exposed at the part where it should branch. Good.

Conversely, this means that if branching is not required, an appropriate coating may be applied over the entire length of the fin tract. As described in detail above, even when the electric wire having a crimp-peelable attachment surface of the present invention is fixed as necessary, such as during routing, the fixed side is a crimp-peelable type that is complementary to the attachment surface. Fasteners can be used, there is no need for specially designed or space-consuming binding, and at least between wires of the same configuration. By making some of the conductors bare, it is easy to branch out or integrate the cable channels as necessary, and the product value is high in terms of appearance, and it can be used well even when multiple lines are required. It can have many and remarkable effects.
