The present invention relates to a lead cable for electrically connecting a substrate or the like of an electronic device.

The substrate mainly installed inside the various electronic devices is assembled with electronic accessories to perform a specific operation for driving the device. Many of these substrates are connected to complete the electronic device. Therefore, a lead cable made of electric wire is used as an application for inputting and outputting an electrical signal between the substrates.

The lead cable may be used not only for interconnecting the substrates but also for applying a signal on one side to a driving position on the other side in the substrate. The line number of the lead cable applied according to the type of the input / output signal may be used. It is decided to use the lead cable branched to the required number.

The lead cable has a plurality of wires in a group to connect to the substrate, and both ends of the lead cable are peeled off so that the inner core wire is exposed to a predetermined length, and the connection hole is already drilled to the installation position on the substrate. Directly connected by a method to be inserted into, or indirectly connected using a connector or the like is known.

In the conventional lead cable, a flat multi-core flat cable having a structure in which core wires are arranged at regular intervals to be integrally wrapped around the outside thereof is mainly used.

The flat cable has a structure in which a relatively flexible synthetic resin material is molded outside the core wires arranged at a predetermined interval, and has flexibility in one direction. The reason for this is to have a flat shape with a relatively thin thickness, so that it is somewhat free to bend up and down in the perpendicular direction of the plane, while it is impossible to bend left and right in the front direction. Therefore, in consideration of such one-way bendability, the position where the substrates are in contact with each other should be kept at a constant position. In other words, when the substrate and the other substrate are designed to be connected by the flat cable, the connection position is necessarily limited to be on the same straight line, so that there is a lot of difficulty in the circuit configuration and arrangement of the electronic accessories arranged inside the substrate. It causes the size of to increase.

Then, after limiting the input and output positions between the substrates to a predetermined position in the limited sized substrate, it takes a lot of time and effort to arrange the remaining accessories such as the IC chip and to configure the circuit, resulting in a circuit design cost. There is an increasing disadvantage. This difficulty in circuit configuration leads to greater design and fabrication difficulties in circuit configurations that allow the flat cable to connect to different locations within the same substrate.

When the flat cables are connected to the substrate, the core wires arranged therein as conductors are exposed to allow electrical signals to be input and output. Therefore, both ends of the flat cable to be cut in consideration of the spacing and the connection position, etc. in the case of connecting between the substrates and in the substrate is accompanied by the peeling of the skin to a certain length.

The method of exposing the core wire to expose the core wires in order to connect the conductors in this way is to remove the end portion of the core in advance at the time of manufacture, so that the core wire is exposed, and the worker may peel off one by one during use. When the coated end is peeled off during the manufacturing process as described above, the exposed core wires may be bent or even cut during the distribution process, so that normal connection to the connection of the perforated substrate may be impossible to maintain a certain interval. . In addition, even if it is distributed without being damaged, such as bending, foreign matter comes into contact with the core wire and causes a bad connection state, which causes malfunction.

In addition, as in the latter case, when the user peels off the end directly during connection, it takes a lot of time, and makes the worker feel troublesome, and peeling off the coating is relatively easy. Or irregularly peeling off the coating, resulting in poor connection.

Therefore, in recent years, as shown in Japanese Utility Model Publication No. 63-202012 and Japanese Patent Application Laid-open No. Hei 1-217802, holders are formed as a means for preventing the cutting of the coating and the spreading of the coating part easily to be peeled off at the end of the cable. One is known to have the effect that the connection work can be made easily and quickly.

However, according to this structure, the number of the wires must be made differently according to a wide variety of electronic devices and uses, and thus, there are closed ends in which production costs required for producing the molds and producing them in different processes are greatly increased.

An object of the present invention is to provide a lead cable to protect the core wire to be connected, it is possible to perform a quick connection work by simply removing the protective body to protect it.

Another object of the present invention is to provide a lead cable that can be connected to bend to a free position to reduce the production cost, by cutting and using the appropriate number of core strands.

It is still another object of the present invention to provide a lead cable that can be firmly connected to prevent malfunctions and failures such as cutting of core wires during use.

Another object of the present invention is to provide a lead cable which is capable of connecting a plurality of input signals to a required position on the input side.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention and the cable line portion 100 is wrapped around the outer surface of the core wires 110 to be insulated (120); The sheath 120 is cut into the both ends of the cable line part 100 so that the sheath 120 is formed inside the preparative line 330 formed at a position in consideration of the length of the core wire 110 to be connected to the substrate. Holders 200 and each molded to be wrapped in a body 210 having a predetermined width on the outer surface; Supported with a predetermined width in the middle of the protective coating 320, which is located outside the divider 330 cut at both ends of the cable line portion 100, and protects the end of the core wire 110 exposed to be connected to the substrate It consists mainly of the protection part 300 which shape | molded the piece 310. As shown in FIG.

The cable line part 100 is a structure part for connecting core wires 110 therein to be parallelly spaced at regular intervals and electrically connecting between the electromagnetic plates or between the substrate and the electronic device to apply input and output signals. . Accordingly, the core wires 110 wired therein select a single wire from among the wires having good electrical conductivity, so that the core wires 110 can be directly connected to another substrate while partially exposing the ends of the core wires 110. The core 110 has a thickness of about 1 mm or less, and relatively thin lines are generally used to minimize the total volume of the lead cable in which the multiple cores 110 are repeated in parallel. Therefore, when the cores 110 are formed by twisting very thin wires into multiple strands, the multicores may be scattered or bent when the thin wires constituting the multiple wires are scattered or bent. The one of the disconnected wire having the necessary thickness is mainly used.

The cable line part 100 which mainly connects between board | substrates has the core wires 110 exposed at both ends, and is connected to the board | substrate 10 directly or through the connector 20 for connection, respectively. The outside of the core wires 110 are covered with an insulator coating 120 to protect electricity from being conducted only through the core wires 110 therein. The core wires 110 are used according to the purpose of the substrate and the number of signals input and output. A different number of is selected.

Therefore, in the conventional case, the number of core wires 110 to which a signal is applied according to the type and use of the electronic device to be installed in the related art is already determined at the time of manufacture, and a flat cable type having an appropriate number of core wires 110 is selected. It was used. In this case, very many kinds of core wires 110 are required according to various electronic models and designs, and the production cost is increased because each core player must be manufactured at the time of manufacture, and the use of other than the proper number of core wires is used. Not doing so, there was a discomfort that makes you feel uncomfortable.

The most important structural feature of the present invention is to allow each of the core wires 110 to be branched at both ends of the cable line part 100, and then simply expose the core wire 110 to a length necessary for connection, and to a free position. The cable line unit 110 is bent to connect an electrical signal to a desired position.

That is, in FIG. 1, the completed state of the present invention is shown as an example, and one end of the protective coating 320 and the support piece 310 which are protecting the end of the core wire 110 for connection to the substrate 10 or the like. This shows the separated state.

The cable line part 100 mainly used in the present invention forms a sheath 120 so as to surround each core wire 110 separately as shown in FIGS. 1 and 2 and each of the plurality of separated unit wires 130 is provided. It is desirable to combine and use it as a lead cable for unit use. The reason is that the cable line portion 100 composed of the respective wires 130, as shown in the figure, has no directivity in bending, and thus maintains autonomy freely bent, bent, or twisted, so that the user can easily This is because an electrical signal can be connected in a state.

When the cable line unit 100 is formed of separate wires 130 as described above, the body 210 is formed at both ends of the synthetic resin material to prevent the wires from scattering, and the core wires necessary for connection ( Molding the body 210 to maintain the interval of 110.

The holder part 200 couples the respective ends of the wires 130 as the body 210 to both ends thereof, so as to accurately maintain the gap between the core wires 110 necessary for the connection, and to fix the substrate 10 to the substrate 10. It is a structure that performs a role that helps to do the work conveniently.

Therefore, the body 210 is molded by a method of injecting the wire 130 at both ends of the cable line part 100 into the synthetic resin material into the synthetic resin material 330 in consideration of the length to be connected. The body 210 has a width and a height to the extent that each of the wires 130 are wrapped, mainly when molded by the injection method, is partially melted with the outer surface of the wire 130 made of a synthetic resin, integrated It is fixed and attached as shown.

As such, the body 210 fixed to the inner side of the core wire 110 exposed for the connection not only helps to hold a worker's hand when connecting to the substrate 10 but also has a intensive force applied during the connection. It is convenient.

The protection part 300 is a structure part that protects the exposed part so that the core wire 110 of the cable line part 100 is connected to the substrate 10.

As shown in FIG. 1, the core wire 110 is positioned when the substrate 10 is connected to the outside of the divider line 330 formed by cutting the coating 120 at both ends of the cable line part 100 to a predetermined length. By forming the support piece 310 in the middle so as to integrally connect the protective coating 320 to protect them at the same time, the core wires 110 are exposed during flow to prevent foreign matters from being buried at the same time, the core wires 110 It will protect the warp.

The support piece 310 is molded by a method of injection mainly to surround the outer surface of the protective coating 320 with a synthetic resin material, it is fixed and attached integrally with the protective coating 320. Therefore, when a force is applied in a direction to be separated from the body 210 by using the support piece 310 during the connection operation, as a result of the respective protective coatings 320 are peeled off at the same time, the inside of the protective coating 320 Protected core wires 110 are exposed.

Thus, both ends of the support pieces 310 and the body 210 are simultaneously molded in a state in which the wires 130 of the cable line part 100 are placed in parallel, so that the shapes and configurations of both sides have the same symmetrical shape. When the cover 120 is cut to the intermediate position between the support piece 310 and the body 210 and separated using the support piece 310, the core wires 110 are simultaneously exposed to a length necessary for connection. will be.

According to the use and the kind of the electronic device installed as in the prior art of the present invention having the above configuration, the number of the wires 130 of the cable line portion 100 is already determined, and both ends of the support piece 310 There is a method to be wrapped in the body and the body 210, but it is possible to manufacture a number of molds in accordance with the number of the wires (130) of each, it is cumbersome and costly, which is undesirable.

Accordingly, in the present invention, as shown in FIG. 1 and FIG. 4, the notch grooves 211 and 311 are dug into the same position in the middle of the support piece 310 and the body 210, respectively, in the required position. The support piece 310 and the body 210 are to be cut. The cutout grooves 211 and 311 are positioned at the intermediate positions through which the respective wires 130 pass, as shown in FIGS. 2 and 3, so that the cutout grooves 211 can be easily cut. It can be artificially bent by the user in position.

As such, the reason why the notch grooves 211 and 311 are dug into the upper and lower surfaces of the body 210 and the support pieces 310 on both sides, respectively, is a core wire 110 that is commonly used when manufacturing a lead cable. In order to form a plurality of core wires 110 in consideration of the maximum number of uses, the user can cut and use the body 210 and the support piece 310 of both ends at the required position with the number of the required capacity. will be.

According to the effects, first, a lead cable in which core wires 110 are formed can be immediately prepared and connected to a suitable use in a connection operation of the substrates 10, and a second end of the cable line part 100 is connected to the substrate 10. After the connection, the other side is divided into the core wire 110 of the required number and divided into several to be connected separately. That is, for example, in the case where ten core wires 110 of the cable line part 100 are formed and want to branch them to other positions in the substrate 10, the terminal on the output side is designed by the core wires 110 at the same time. In the case where the other side to which the signal is applied requires only two signals out of the ten output signals, the other position requires three signals, and the other position requires the application of five signals. Accordingly, after one side of the core wire 110 is connected in a state passing through the inside of the wires 130, the other side of the support piece 310 and the body at the position of the notch grooves 211, 311 in the same manner as described above. By cutting 210, the two branches and three and the remaining five wires 130 are respectively connected to the required position. Therefore, the variety of circuit design and operator's convenience will be induced. Third, since the core wire 110 of the maximum capacity can be used without making a number by each core wire 110, the production cost is cheap, intermediate distributors also have a core player for each use with many unnecessary specifications Since it is not possible to prevent economic profits and inventory, and when the user also purchases, to prevent the need to buy a variety of choices that are always appropriate, it is possible to prevent the case of throwing away due to the wrong purchase.

Then, after connecting the core line 110 to the substrate 10 at all times, the cable line portion 100 continues to flow and the core line 110 is bent or cut, and the core line 110 is formed by the flow during use. In order to prevent the malfunction due to the departure from the (10), as a rule of the body 210 as shown in Figure 3 it is possible to add a hook 220 separately.

As illustrated in FIG. 7, the hook 220 protrudes the locking piece 221 to the front end, and protrudes the guide 224 up and down to face the rear end of the hook groove 223 so as to pass through the rail groove 223. . The shape of the engaging piece 221 is inclined backward from the end surface, the jaw portion 222 perpendicular to the end is formed and assembled into a hole 11 drilled in the substrate 10, the back surface of the substrate 10 Let it hang

As shown in FIG. 1, the rail groove 223 is drilled to a corresponding width and height to engage the body 210 of the holder 200. At this time, the groove 210 is excavated vertically to one side both sides of the body 210 for a more complete coupling with the body 210, when assembled to the hook 220 and the body 210, the guide 224 Let the inside of the hook hang. Therefore, the hook 220 coupled to the body 210 is to be coupled in a state in which the left and right movements are prevented, and the coupling of the hook 220 is connected to one side of the body 210 or up and down the wires ( It forms an extension 230 that is independent of surrounding 130.

The extension 230 is formed to have a position to couple the hook 220. Therefore, the wire 130 is not passed through the extension portion 230 to the center, and instead the hook 220 is installed.

As shown in FIG. 4, the triangular protrusion 225 is integrally protruded into the middle portion of the rail groove 223 in which the hook 220 is prevented from flowing in the state in which the hook 220 is installed. By being caught in the notch groove 211 dug into the body 210 as described above, the hook 220 is prevented from flowing in the upper and lower directions to the substrate 10 in a state that is firmly coupled to the body 210. It is fitted. Therefore, the hook 220 is expected to smoothly operate the electronic device by preventing the core wire 110 from being bent or separated as a result of firmly fixing the body 210 to the substrate 10.

Although the hook 220 may be installed at both ends of the body 210 as shown in FIG. 3, even if only one is installed at one side thereof, the hook 220 may be firmly supported.

2 illustrates a state in which the core wire 110 is manufactured in consideration of the case in which the core wire 110 is used to the maximum (typically, the core wire is used within 40), and the hook 220 is installed at the center thereof. The extension portion 230 is formed in the body 210 so that the hook 220 may be used to connect to the hook 220, and the user cuts the necessary position in consideration of the required number of wires 130. Do it.

5 illustrates another embodiment of the present invention, and shows an example in which the holder part 200 and the protection part 300 are applied to a flat multi-core flat cable. In this case, a divider line 330 is formed between the body 210 and the support piece 310 to separate the protection part 300 during use to expose the core wire 100 to be used for connection. This is difficult to expect the function of branching to the required number of core wires 110 and freely bent to connect to the desired position, but it is possible to have the convenience and effect of protecting and connecting the core wires 110.

First, as described above, the present invention can be manufactured by integrating the maximum number necessary for connecting the core wires 110, and then cutting the required number of signals, thereby simplifying manufacturing and lowering the cost. By reducing the burden and secondly bending or twisting freely to connect to the desired position, the circuit configuration is simple, and the design cost can be reduced, and the third hook can be installed at the proper position and firmly connected to the board so that the core wire To prevent damage or departure from the substrate. Fourth, the cores to be connected should be manufactured and distributed in a protected state with a protective coating, and separated and connected during use, thereby preventing malfunctions such as damaging the core wires and contact with foreign substances. Is a very useful invention such as designing a circuit configuration and a component configuration in a free position by allowing the other side to be freely branched and connected after connecting to the same position as a whole.
