Description

  The present invention relates to a cable harness suitably used for electrically connecting terminals of an electronic device or the like and a manufacturing method thereof.

  In recent years, in the field of the electronics industry, for example, electronic devices have been rapidly reduced in size, weight, functionality, etc., and with this, electrical cables used when connecting terminals of electronic devices are also being developed. Thinning and space saving are required. Here, as the electric cable, for example, a flexible printed circuit (FPC) board used in a connection part (bent part) between a personal computer body of a notebook type personal computer and a liquid crystal display, a bent part of a mobile phone such as a folding type, etc. It is well known.

  By the way, recently, rotary type mobile phones, specifically, mobile phones etc. in which a connection part between a liquid crystal display and a mobile main body is rotatably provided have been distributed in the market. In the connection part of a telephone, it has become difficult to apply the FPC board described above. The reason for this is that the entire FPC board is in the form of a film, so that it may be difficult to physically accommodate it at the connecting portion. In addition, for electronic devices such as mobile phones, it is expected that there will be an increasing demand for miniaturization in the future, and there is a limit to using an FPC board for the connection between each terminal of such electronic devices. There is a problem that there is.

  Therefore, coaxial cables have been used in connection portions that cannot be handled by such a film-like FPC board. As a coaxial cable, for example, an insulator is formed on the outer periphery of the central conductor, and an outer conductor is provided on the outer periphery of the insulator by braiding a thin metal wire, lateral winding, winding of a metal foil, etc. The thing provided with the protective coating layer is known (for example, refer patent document 1).

  In such a coaxial cable, the end portions are aligned and aligned at a predetermined pitch, and then the protective covering layer is partially removed with a predetermined width over the parallel direction of the coaxial cable, and a ground bar is formed on the exposed external conductor. Connected. Further, the end portion of each coaxial cable is processed so that the central conductor having a predetermined length is exposed by removing the insulator, the outer conductor, and the protective coating layer.

  And the connector for connecting with an external terminal is mounted | worn with the edge part of such a coaxial cable (for example, refer patent document 2). Specifically, the electrical connector disclosed in this publication includes a housing in which slots, which are U-shaped grooves, are arranged side by side, and the end of each coaxial cable is inserted into each slot, and each coaxial cable is inserted. By connecting the central conductor of the cable and the contact portion provided in the housing, an electrical connector with a coaxial cable is obtained.

  Such an electrical connector with a coaxial cable is a process in which a coaxial cable and an electrical connector are individually manufactured and then electrically connected when both are assembled. Specifically, each coaxial cable is inserted into the electrical connector. Thus, there is a problem that productivity is very poor because a process for electrical connection and a process for electrical connection between the ground bar and the electrical connector are necessary.

  In addition, the coaxial cable has been extremely thinned in the outer diameter of the cable, and a dedicated electrical connector has to be manufactured in accordance with the design of the coaxial cable.

  Note that since the FPC board generally has a structure in which wirings are provided on the board, it is difficult to prevent mutual interference of electromagnetic waves between the wirings.

In the tenth aspect, since a plurality of cables (coaxial cables) are independent from each other, it is possible to save space by bundling or twisting the plurality of cables. Thereby, for example, even if it is difficult to physically accommodate an FPC board such as a connection part in a rotary mobile phone or the like, it can be reliably accommodated by bundling a plurality of cables. .

  The cable harness of the present invention includes a plurality of cables and a fixing portion that fixes the vicinity of at least one end of these cable groups. Here, the cable in the present invention has at least a covered electric wire composed of a central conductor and an insulator layer provided around the central conductor. For example, an external conductor (shield) is provided around the covered electric wire. It includes a cable provided and a cable in which the outer conductor of such a covered electric wire is covered with an outer covering layer.

  Here, the central conductor (conductor) included in such a cable may be a single wire having a predetermined diameter, for example, a single wire having a diameter of about 30 μm to 0.1 mm, or a multi-core wire, for example, A plurality of ultrafine wires having a diameter of about 10 to 80 μm may be assembled. Further, the structure of the cable in which an insulator layer is provided around the central conductor may be a structure in which an insulator layer is covered on a single wire or a structure in which an insulator layer is covered on a multi-core wire.

  In the present invention, examples of the center conductor include a tin-containing copper alloy, a chromium-zirconium-containing copper alloy, or an in-situ fiber reinforced copper alloy. It is preferable in terms of bending resistance. Further, when the central conductor is a single wire made of an in-situ fiber reinforced copper alloy, the tensile strength of the central conductor is increased, and as a result, a cable harness in which the central conductor is difficult to break can be realized.

  Here, the conducting wire made of the in-situ fiber reinforced copper alloy is a copper matrix reinforced with fibers, and particularly refers to a wire formed in situ, that is, in a step of forming a wire. For example, it refers to a wire rod containing in-situ formed fibrous silver having a maximum diameter of 2.5 μm or less and an average diameter of 1.0 μm or less in a copper matrix.

  For example, the in-situ fiber reinforced copper alloy is formed by swaging an alloy material made of copper with a silver content of 1 to 25% by weight and the balance substantially, and then performing a first cold drawing. Applying wire processing, then solution treatment, and then applying a second cold wire drawing to form a wire silver in situ in a copper matrix to obtain a wire, using at least one wire It is obtained by forming a conducting wire. In addition, as an alloy material used as a material, it is not limited to what was mentioned above, For example, silver content rate is 1 to 25 weight%, zirconium content rate is 0.01 to 8 weight%, and remainder is substantially copper. An alloy material can also be used.

  The wire made of such a composite material can ensure high conductivity when current flows through the copper matrix, and mechanical strength can be ensured by fiber reinforcement, and has contradictory characteristics of high mechanical strength and high conductivity. It will have both.

  Examples of the insulator layer provided on the central conductor in the present invention include a coating layer made of acrylonitrile-butadiene-styrene (ABS) resin, polyester, fluorine resin, polyimide resin, polyolefin resin, or the like. And enamel coating. In terms of low dielectric constant, preferable for diameter reduction, and bending resistance, fluorine resin, polyethylene, or fluorine resin is preferable, and ABS resin is most preferable. In addition, when using the ABS resin as a material for forming the insulator layer as described above, the ABS resin may be used alone, but other than the ABS resin, for example, various resins such as polystyrene ( PS), polycarbonate (PC), nylon (PA) and the like may be used, and in addition, those added with various additives such as a curing agent and a thickener may be used.

  The cable harness of the present invention collects a plurality of the cables described above to form a cable group, and a fixing portion that is formed of an insulating material in the vicinity of one end portion in the longitudinal direction of the cable group and integrally fixes these cables. It has. Here, “the state in which the entire cable is fixed integrally” refers to a state in which the insulating material is in close contact with the outer peripheral surfaces of the plurality of cables and the movement between the cables is regulated (fixed). . Such a fixing | fixed part can be formed comparatively easily so that it may become a predetermined shape with a shaping | molding processing technique, for example. For this reason, the manufacturing process of a cable harness can be simplified.

  Further, in the present invention, a plurality of cables are aligned at a predetermined pitch, for example, 0.2 mm pitch, and in this state, the entire cable is fixed by the fixing portion, whereby the fixing portion is arranged in the parallel direction of the cables. It extends over and becomes a film shape. The thickness of the fixing portion varies depending on the outer diameter of the cable, but is preferably about 1 mm or less, more preferably about 0.5 mm or less. Thereby, a fixed part becomes a shape where the thickness is very thin. Moreover, since this fixing | fixed part is formed with the insulating material (for example, resin etc.), it has flexibility.

  Furthermore, in the present invention, the fixing portion for fixing at least one end portion of the cable group and the cable are covered with an outer conductor made of a material containing metal. For example, the outer conductor serves as a shield between cables and in a high frequency region. In particular, in the present invention, by continuously covering the fixing portion and the cable constituting the cable harness with the outer conductor, each cable is individually covered with the outer conductor, and the surface of the fixing portion is also covered with the outer conductor. Therefore, a cable harness having excellent shielding performance can be realized.

  In the present invention, it is preferable to form a metal plating layer as such an external conductor. This is because it is possible to realize a cable harness in which the desired shield performance (about 20 dB or more) is ensured and the flex resistance of the cable itself is improved. Thus, when forming a metal plating layer as an external conductor, it is preferable to perform a predetermined surface treatment on at least the surface of the insulator layer before forming the metal plating layer. Of course, you may perform the same surface treatment also on the surface of a fixing | fixed part.

  Here, the predetermined surface treatment is not particularly limited as long as it roughens the surface, improves the wettability of the surface, and improves the adhesion of the shield to the insulator layer. An etching process etc. are mentioned. For example, when an ABS resin is used as the material of the insulator layer, it is preferable to perform a surface treatment by chromic acid etching using chromic anhydride. Thereby, the wettability of the surface of the insulator layer made of ABS resin is increased, and the adhesion with the metal plating layer (shield) formed thereon is improved.

  In the present invention, it is preferable to form a metal plating layer as an outer conductor formed around the insulator layer. This metal plating layer may be formed by electroless plating or electroless plating and electroplating. And may be formed in combination. Examples of the metal plating layer include copper, silver, nickel, gold, etc., or composite plating or alloy plating thereof. The thickness of the metal plating layer thus formed is preferably 0.5 μm to 6 μm, more preferably 2 μm to 6 μm. This is because if it is thicker than this, there is a problem in bending resistance.

  In the present invention, since the fixed portion and the cable are continuously covered with the outer conductor as described above, the fixed portion becomes the ground bar by electrically connecting the outer conductor and the ground terminal. Therefore, a ground bar like a conventional product is not necessary. However, a ground bar may be separately provided in the cable harness.

  Furthermore, as the cable harness of the present invention, an outer covering layer (sheath) is preferably provided on at least the outer conductor, preferably on the surface including the fixing portion and the outer conductor of each cable, and more preferably, It is preferable that the fixing portion and each cable are integrally covered with the outer covering layer. This is because the strength of the entire cable harness is improved. Here, examples of the material for the outer coating layer include a fluorine-based resin, an olefin-based resin, a polyester, a polyurethane, an ABS resin, and a polyimide.

  In the present invention, it is preferable that each cable is individually covered with an outer conductor and then individually covered with an outer covering layer. Accordingly, the plurality of cables are individually independent, and the plurality of cables can be bundled or twisted to save space. Therefore, for example, even a portion that is difficult to physically accommodate in an FPC board such as a connection portion in a rotary cellular phone or the like can be reliably accommodated by bundling a plurality of cables.

  On the other hand, such a cable harness of the present invention is insulated near at least one end portion in the longitudinal direction of a cable group composed of a plurality of cables having at least a central conductor and an insulating layer provided around the central conductor. A plurality of cables are integrally covered with a material to form a fixing part for fixing the plurality of cables, and the plurality of cables protruding from the fixing part and the fixing part are continuously covered with an external conductor. After that, a part of the fixed part corresponding to one end of the cable group and a part of the plurality of cables are removed so that the central conductor is exposed, thereby forming a connection terminal to be a connection part with the external wiring. It is manufactured by.

  As described above, in the present invention, the coaxial cable and the fixed portion to be the connector portion are continuously manufactured on the same line, so that the coaxial cable and the electrical connector are separately manufactured as in the conventional case. The manufacturing cost can be greatly reduced. In addition, since the process of electrically connecting the coaxial cable and the electrical connector as in the prior art is not required, the cable harness can be manufactured with high productivity. The coaxial cable refers to a cable in which an outer conductor is provided around a covered electric wire or a cable in which the outer conductor of this cable is covered with an outer covering layer.

  In the present invention, the connection terminal is formed after the cable and the fixing portion are covered with the external conductor. However, of course, after the connection terminal is formed, the cable and the fixing portion may be covered with the external conductor. Good.

  According to the present invention, one end portion of the cable group is covered and fixed with an insulating material, and the connection terminal is formed by exposing the central conductor of the cable to the fixed portion. It can be provided with high productivity. In addition, since the cable and the fixed portion are continuously covered with the outer conductor, a cable harness having excellent shielding performance between cables and in a high frequency region can be realized. In particular, by making the plurality of cables individually independent, the plurality of cables can be bundled or twisted to save space. That is, for example, even a portion that is difficult to physically accommodate in an FPC board such as a connection portion in a rotary cellular phone or the like can be reliably accommodated by bundling a plurality of cables.

  Hereinafter, the best mode for carrying out the present invention will be described.

(Embodiment 1)
1A and 1B are schematic views illustrating a cable harness according to Embodiment 1 of the present invention, in which FIG. 1A is a plan view, FIG. 1B is an enlarged view of an end portion, and FIG. FIG. 2 is an enlarged cross-sectional view of the main part of FIG. 1, where (a) is a cross-sectional view along AA ′, (b) is a cross-sectional view along BB ′, and (c) is CC- It is sectional drawing. As shown in FIGS. 1 and 2, the cable harness 10 of the present embodiment includes a plurality of cables (covered electric wires) 20 having a center conductor 21 and an insulator layer 22 provided around the center conductor 21. To do. Each of these cables 20 is arranged in parallel in the width direction at a pitch of about 0.2 mm. Here, as the cable 20, in this embodiment, an ABS resin is formed by extrusion molding on the outer periphery of a central conductor 21 having an outer diameter of about 0.03 mm made of an in-situ silver fiber reinforced copper alloy (silver content: about 10%) The insulator layer 22 made of is formed to have an outer diameter of about 0.08 mm.

  Moreover, the fixing | fixed part 30 which is formed with an insulating material and fixes each cable 20 whole integrally is provided in the vicinity of the both ends of the longitudinal direction of the cable group 20A comprised by such each cable 20. FIG. In the present embodiment, the fixing portion 30 is formed along the direction in which the cables 20 are arranged side by side, has a thickness of about 0.5 mm, and has a film shape as a whole.

  Furthermore, the convex part 31 is provided in the edge part of the fixing | fixed part 30, ie, the upper end part which opposes the both ends of 20 A of cable groups, by removing continuously along the parallel arrangement direction of the cable 20. Yes. More specifically, the upper end portion of the fixing portion 30 and a part of each cable 20 are continuously removed along the direction in which the cables 20 are juxtaposed, and the center conductor 21 of each cable 20 is exposed. The center conductor 21 of each cable 20 exposed in this way becomes a connection terminal 32 which is a connection portion with an external terminal (not shown). The connection terminals 32 are arranged in parallel in the width direction. Thereby, the convex part 31 of the fixing | fixed part 30 functions as a connector part connected to an external terminal. In addition, although the convex part 31 is good also as a connection part as it is, it may be pressed from the upper and lower sides and crushed until it becomes desired thickness, and may be used as a connection part.

  Thus, in this embodiment, since each cable 20 and the fixing | fixed part 30 are provided integrally, and the connection terminal 32 is provided in the fixing | fixed part 30, a conventional coaxial cable and an electrical connector are connected. Not only does the assembly work such as the electrical connection process become unnecessary, but the overall structure is integrated, so the strength can be increased.

  In the present embodiment, the outer peripheral surface of each cable 20 and the surface excluding the upper surface and the front end surface of the convex portion 31 of the fixing portion 30 are continuously formed by the outer conductor 40 made of a metal plating layer and having a thickness of about 2 μm. Is covered. Each cable 20 is individually covered with the outer conductor 40 to become the coaxial cable 25 and is electrically connected via the outer conductor 40 formed on the surface of the fixed portion 30. The external conductor 40 is electrically connected to a ground terminal (not shown). For this reason, the fixing | fixed part 30 plays the role as a ground bar. Therefore, in the cable harness 10 of the present embodiment, it is not necessary to provide a ground bar separately from the fixing portion 30, so that the number of parts can be reduced and the cost can be reduced.

  On the other hand, such an external conductor 40 also serves as an electromagnetic wave shield. Specifically, since each cable 20 is individually covered with the outer conductor 40, mutual interference of electromagnetic waves between adjacent cables 20 can be prevented at a high level, and sufficient electromagnetic waves can be obtained even in a high frequency region. Shield performance (about 25 dB or more) can be obtained.

  Here, such an outer conductor 40 is preferably formed thick in order to enhance the electromagnetic shielding effect. However, although it varies depending on the material of the outer conductor 40, if the outer conductor 40 is too thick, the rigidity is increased, which is not preferable in terms of bending resistance. For this reason, the thickness of the outer conductor (metal plating layer) 40 is preferably in the range of 0.5 μm to 6 μm, more preferably in the range of 2 μm to 6 μm. In the present embodiment, the outer conductor 40 made of a metal plating layer having a thickness of 2.0 μm made of silver formed by electroless plating is provided. Thereby, the bending resistance of each coaxial cable 25 can be maximized while ensuring the electromagnetic wave shielding effect.

  Moreover, in this embodiment, each coaxial cable 25 and the fixing | fixed part 30 are covered with the outer coating layer (sheath) 50 which consists of polyurethane. Specifically, the outer covering layer 50 is formed on the surface of the outer conductor 40 that covers each cable 20 and the fixing portion 30, and continuously covers the fixing portion 30 and the coaxial cable 25. Thereby, the intensity | strength of the cable harness 10 whole can be improved. More specifically, each cable 20 is individually covered with an outer conductor 40 and is individually covered with an outer covering layer 50 from above. As a result, the plurality of coaxial cables 25 are individually independent, and the coaxial cables 25 can be bundled or twisted to save space. Therefore, for example, even if it is difficult to physically accommodate an FPC board such as a connection portion in a rotary cellular phone or the like, it can be reliably accommodated by bundling a plurality of coaxial cables 25. it can.

  Hereinafter, with reference to FIG.3 and FIG.4, an example of the manufacturing method of the cable harness 10 mentioned above is demonstrated. 3 and 4 are schematic views illustrating an example of a manufacturing process of the cable harness according to the first embodiment of the present invention.

  First, as shown in FIG. 3A, a plurality of cables 20 including a central conductor 21 and an insulator layer 22 are drawn out at a predetermined pitch width, for example, about 0.2 mm pitch width in this embodiment. Here, a plurality of cables 20 in which the insulator layer 22 is formed around the center conductor 21 may be prepared in advance, and a plurality of cables 20 may be drawn out. Alternatively, the cable 20 may be formed by forming the insulator layer 22 around the center conductor 21 by extrusion molding. Each cable 20 may be pulled out continuously while manufacturing the cable.

  Next, as shown in FIG. 3B, the vicinity of both ends of the aligned cable group 20A in the longitudinal direction (here, one end of the cable group 20A is illustrated and described) is covered with a resin material (molding). Then, the entire cable 20 is integrally fixed along the juxtaposed direction. In the present embodiment, the fixing portion 30 to which the plurality of cables 20 are fixed in this way is formed here by a molding technique.

  Next, as shown in FIG. 3C, the surface excluding the distal end surface of the fixing portion 30 and the respective surfaces of each cable 20 are covered with an external conductor 40 made of, for example, a metal plating layer. In the present embodiment, a metal plating layer made of silver having a thickness of 2.0 μm is formed as the outer conductor 40 by electroless plating. Thus, each cable 20 is individually covered with the outer conductor 40 to become the coaxial cable 25. Thus, in this embodiment, since each cable 20 is individually coat | covered with the outer conductor 40, the shield performance between adjacent cables 20 is obtained, and the shield performance outstanding also in the high frequency area | region is obtained. Can do.

  Subsequently, as shown in FIG. 4A, the surface excluding the front end face of the fixing portion 30 and the respective surfaces of the coaxial cables 25 are covered with an outer covering layer 50 made of polyurethane. For example, in the present embodiment, the outer coating layer 50 is formed by dipping. Here, the periphery of the coaxial cable 25 is individually covered by the outer covering layer 50. As a result, the coaxial cables 25 are in an independent state.

  Thereafter, as shown in FIG. 4B, the end of the fixed portion 30, specifically, the upper end facing the one end of the cable group 20 </ b> A is removed (cut) along the direction in which the coaxial cables 25 are juxtaposed. Etc.), the central conductor 21 of the coaxial cable 25 is exposed. Thereby, the connection terminal 32 used as a connection part with an external terminal is formed in the fixing | fixed part 30, and the fixing | fixed part 30 becomes a connector part. Then, the cable harness 10 in which the central conductor 21 of the coaxial cable 25 is used as the connection terminal 32 and the fixing portion 30 functions as a ground bar and the cable group 20A and the fixing portion 30 are integrally provided is completed.
