Description

Cable harness, cable harness with connector and connection structure of cable harness

The present invention relates to a cable harness having a plurality of coaxial cables and insulating cables arranged in parallel and an outer conductor of the coaxial cable being grounded, a cable harness with a connector, and a connection structure of the cable harness.

In recent years, with the widespread use of mobile phones, small video cameras, etc., in addition to making these electronic devices smaller and lighter, higher speed and higher image quality are required. To meet these requirements, extremely thin coaxial cables are used to connect the device main unit and the liquid crystal display, and wiring in the devices. Also, for ease of wiring, multiple coaxial cables are integrated together. A cable harness is used.

A coaxial cable used for a cable harness is configured by arranging a central conductor, an inner insulator, an outer conductor, and a jacket from the inside in a coaxial manner. The central conductor is formed, for example, by twisting seven copper alloy wires, and the outer surface thereof is covered with an insulating material such as Teflon (registered trademark) resin to form an internal insulator.

The outer conductor disposed on the outer peripheral surface of the inner insulator is formed by, for example, spirally winding a copper alloy wire, and, for example, two polyester tapes are wound on the outer surface and fused together to form a jacket. . In addition, the copper vapor-deposited tape may be wound around the outer surface of the outer conductor with the copper vapor-deposited surface inside, and the outer conductor may be wound in two layers with the winding direction of the copper alloy wire reversed. In addition, a braided structure may be used.

Various types of cable harnesses have been proposed. For example, a plurality of signal transmission coaxial cables and a plurality of power transmission (power supply) cables are ribbon-formed by heat fusion or adhesive. It is known that it is formed by adhering to (see, for example, Patent Document 1).

In addition, for example, a cable harness in which a signal coaxial cable and a power supply coaxial cable are arranged in parallel at a predetermined pitch and integrated with a tape having an adhesive layer on both surfaces thereof is also known (for example, , See Patent Document 2).

Japanese published patent: JP-A-62-86611 Japanese published patent: JP 2000-322943

By the way, as described above, electronic devices such as mobile phones and small video cameras have been further improved in performance, and the amount of information to be processed has also increased. On the other hand, because there is a demand for miniaturization and weight reduction, cable harnesses used in such electronic devices are also required to be mounted with high density, and there is a tendency to form cable harnesses with extremely thin coaxial cables (extremely fine coaxial cables). . Since the coaxial cable is configured to have a center conductor, an inner insulator, an outer conductor, and a jacket, the cross-sectional area of the center conductor is small, and it is necessary to use a coaxial cable as a power cable like the cable of Patent Document 2. Many coaxial cables may be required to supply current.

Also, the cable harness is conductively bonded such that its terminal portion is soldered to terminals arranged at a predetermined pitch on a connector or a board. For this reason, it is required that all the cables constituting the cable harness are arranged on the terminal by being aligned at a predetermined pitch. In particular, when the cables are extremely thin, the arrangement pitch of the cables is small, and positional displacement in sub-millimeter units tends to be a problem.

Therefore, it is required that the cables constituting the cable harness are arranged with high accuracy. Therefore, it is important to fix each cable to the ground bar at a predetermined pitch.

In addition, as a cable harness other than the above Patent Documents 1 and 2, there are some signal cables and power cables that are arranged separately, and only the signal cables are connected to the ground bar and fixed, When connecting the terminal portion, it is necessary to perform positioning with the signal cable and the power cable, and the workability is not good.

Therefore, the present invention satisfies the performances of signal cables and power cables, and includes a cable harness including a micro coaxial cable that can be easily and accurately connected to a connector terminal of a terminal portion, a cable harness with a connector, and a cable. An object is to provide a connection structure for a harness.

The cable harness according to the present invention capable of solving the above-described problems is a center conductor, an inner insulator disposed on the outer periphery of the center conductor, an outer conductor disposed on the outer periphery of the inner insulator, and the outer A plurality of coaxial cables having a jacket disposed on the outer periphery of the conductor, a central conductor, and an insulated cable having a jacket disposed on the outer periphery of the center conductor are arranged in parallel, The exposed portion of the outer conductor of the coaxial cable and the jacket of the insulated cable are fixed by being sandwiched by a common ground bar, and the exposed portion is electrically connected to the ground bar.

In the cable harness according to the present invention, the outer diameter Di of the jacket of the insulated cable and the outer diameter Dc of the outer conductor portion of the coaxial cable satisfy Dc (mm) ≦ Di (mm) ≦ Dc + 0.18 (mm). Preferably there is.
Furthermore, it is preferable that the cross-sectional area of the central conductor of the insulated cable is larger than the cross-sectional area of the central conductor of the coaxial cable.

A cable harness with a connector according to the present invention includes the cable harness according to the present invention, wherein each central conductor of the coaxial cable and a central conductor of the insulated cable are connected to a connection terminal of the connector. .

The connection structure of the cable harness according to the present invention includes the cable harness according to the present invention, and each central conductor of the coaxial cable and a central conductor of the insulated cable are connected to a connection terminal provided in an electric circuit. It is characterized by that.
The cable harness connection structure is, for example, a connection structure to a printed circuit board (FPC: Flexible Printed Circuit, PWB: Printed Wire Board, etc.).

Since the insulated cable included in the cable harness of the present invention is composed of the center conductor and the jacket, it has a structure that can easily secure a large cross-sectional area of the center conductor and can satisfy the performance as a power cable.

Also, since the outer conductor of the coaxial cable and the jacket of the insulated cable are sandwiched and fixed by the ground bar, the arrangement state of each cable is not disturbed when the terminal portion is connected to the connector terminal or the like.

The cable harness with a connector provided with the cable harness of the present invention is a highly reliable connector in which the central conductor of the coaxial cable and each central conductor of the insulated cable are connected to the connection terminal of the connector with high accuracy, and the power supply performance is excellent. It is a cable harness with. Moreover, the connection structure of the cable harness in which the cable harness of the present invention is connected to the printed circuit board has the same effect.

Hereinafter, the example of embodiment of the connection structure of the cable harness which concerns on this invention, the cable harness with a connector, and a cable harness is demonstrated.
FIG. 1 is a view showing an example of a cable harness according to the present invention, in which (A) is a plan view of the cable harness, and (B) is an end view as viewed from the F direction in (A). In FIG. 1A, the second ground bar 30 to be described later is not shown in order to simplify the drawing. FIG. 5 shows an enlarged cross-sectional view near the arrow V in FIG.

As shown in FIG. 1, the cable harness 10 has a plurality of coaxial cables 11 and at least one insulated cable 40, which are arranged in parallel.

The coaxial cable 11 is used as a signal cable for signal transmission. In the present embodiment, 37 are provided.
As shown in FIG. 2, the coaxial cable 11 includes a center conductor 15, an inner insulator 14 disposed on the outer periphery of the center conductor 15, an outer conductor 13 disposed on the outer periphery of the inner insulator 14, And an insulating sheath 12 disposed on the outer periphery of the conductor 13, and these are arranged coaxially.

As the coaxial cable 11, for example, a cable corresponding to AWG 44 based on the standard of AWG (American Wire Gauge) is used. In the coaxial cable 11 of the AWG 44, the central conductor 15 is formed by twisting seven strands 15a of silver-plated copper alloy having an outer diameter of 0.020 mm, for example. The internal insulator 14 is made of a fluororesin such as PFA that covers the outer peripheral surface of the center conductor 15 and is formed to a thickness of 0.04 mm by extrusion coating. Further, the outer conductor 13 is formed to have an outer diameter of 0.21 mm, for example, by winding a strand 13a of a tin-plated copper alloy around the outer peripheral surface of the inner insulator 14 in a spiral manner. In addition, the outer cover 12 is made of a fluororesin such as PFA that covers the outer peripheral surface of the outer conductor 13, and in the case of the AWG 44, the outer cover 12 is formed with an outer diameter of 0.26 mm.

The end portion of the coaxial cable 11 is subjected to lead processing, and the center conductor 15, the inner insulator 14, and the outer conductor 13 are exposed in predetermined steps in order from the tip side.

Further, three insulated cables 40 are provided in the present embodiment.
As shown in FIG. 3, the insulated cable 40 has a center conductor 41 and an insulating jacket 42 disposed on the outer periphery thereof, and is configured by coaxially arranging these.

For example, when the coaxial cable 11 has a size corresponding to AWG 44, the insulated cable 40 is a cable corresponding to AWG 38 according to the AWG standard, and the central conductor 41 is, for example, a tin-plated copper alloy wire The outer cover 42 is made of a fluororesin such as PFA that covers the outer peripheral surface of the central conductor 41, and has an outer diameter of 0.21 mm. The diameter of the portion of the center conductor 41 is 0.11 mm, and the thickness of the jacket 42 is 0.05 mm. The thickness of the jacket 42 is thicker than the thickness of the inner insulator 14 of the coaxial cable 11 of the AWG 44.

The insulated cable 40 is a cable used for supplying power, and the cross-sectional area of the central conductor 41 is larger than the cross-sectional area of the central conductor 15 of the coaxial cable 11. Since the insulated cable 40 has a structure including the center conductor 41 and the jacket 42, it is easier to ensure a larger cross-sectional area of the center conductor 41 than the coaxial cable 11.

When the jacket 42 of the insulated cable 40 is formed to have the same outer diameter as the outer conductor 13 layer of the coaxial cable 11, it is sandwiched and fixed by the two

ground bars

20, 30 together with the outer conductor 13 of the coaxial cable 11. Therefore, it is preferable. The jacket 42 has a sufficient thickness so that the jacket 42 does not melt and the insulation characteristics cannot be maintained due to heat generated when the ground bars 20 and 30 are fixed to the coaxial cable 11 and the insulated cable 40. Have When the outer conductor 13 and the insulated cable 40 of the coaxial cable 11 are fixed to the ground bars 20 and 30 by soldering using pulse heat, it is preferable that the jacket 42 of the insulated cable 40 has a thickness of 0.03 mm or more. If a low melting point solder having a melting point of about 230 ° C. is used, even if the insulation cable 40 having a thickness of 0.03 mm is soldered to the ground bars 20 and 30, the jacket 42 does not melt, so that the insulation characteristics are improved. Kept.

Further, the end portion of the insulated cable 40 is also exposed, and the center conductor 41 is exposed to a predetermined length (for example, a length equivalent to the center conductor 15 of the coaxial cable 11) on the end side in the length direction.

As shown in FIG. 1, in the cable harness 10, the outer conductor 13 and the jacket 42 are sandwiched between the ground bars 20 and 30 via solder so that the center conductor 15 and the center conductor 41 are arranged in parallel at a predetermined pitch. The positions of the cable harness 10 and the coaxial cable 11 are fixed.

The ground bars 20 and 30 are plates formed to have a length that covers the outer conductor 15 of all the coaxial cables 11 and the jacket 42 of the insulated cable 12. For example, a conductive metal plate such as a copper plate.

Further, as shown in FIG. 4, the opposing surfaces of the ground bars 20, 30 are fixed to the

cables

11, 40 by the joining member 24 (see FIG. 5). As the bonding member 24, for example, plate solder can be used, but in addition to the plate solder, an anisotropic conductive film (ACF), a non-conductive film (NCF), or the like can also be used. By these joining members 24, the ground bars 20 and 30 and the outer conductor 13 of the coaxial cable 11 are fixed and simultaneously electrically connected. Even when a non-conductive film is used for the joining member 24, the joining member 24 moves so as to fill the gaps between the ground bars 20 and 30 and the

cables

11 and 40 as shown in FIG. Thus, there is a portion where 13 is in direct contact with the ground bars 20 and 30, and electrical connection between the ground bars 20 and 30 and the external conductor 13 is achieved. In this way, the outer conductors 13 can be grounded together in common with the ground bars 20 and 30.

Further, although the joining member 24 does not adhere to the jacket 42 of the insulated cable 40, the joining member 24 moves and solidifies so as to fill the periphery of the jacket 42, so that the insulated cable 40 is orthogonal to the axial direction. It will prevent the movement of the direction. That is, the insulated cable 40 is fixed by the ground bars 20 and 30 and the joining member 24 at least in the direction other than the axial direction.

Since the outer conductor 13 of the coaxial cable 11 and the jacket 42 of the insulated cable 40 are sandwiched and fixed between the ground bars 20 and 30, all the

cables

11 and 40 constituting the cable harness 10 are aligned with high accuracy. And the arrangement state is not disturbed. Therefore, it is possible to accurately connect the terminal portion of the cable harness 10 to the connector terminal or the like. Moreover, while ensuring the large cross-sectional area of the center conductor 41 of the insulated cable 40, the insulation characteristic is also maintained favorable, and the performance as a power cable is good.

A form in which solder is used for both the coaxial cable 11 and the insulated cable 40, a form in which solder is used for the coaxial cable 11 and ACF or NCF is used for the insulated cable 40, the coaxial cable 11 and the insulated cable A configuration in which ACF or NCF is used for both of the members 40 can be employed, but in any configuration using solder, when the joining member (solder) 24 is thermally melted, the ground bars 20 and 30 are used. May be heated once by pulse heat or the like.

The difference between the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 sandwiched between the ground bars 20 and 30 and the outer diameter of the jacket 42 of the insulated cable 40 is when the coaxial cable 11 is AWG42 or narrower than AWG42. Is allowed to be at least 0.18 mm. When the outer diameter of the outer conductor 13 portion of the coaxial cable 11 is 0.17 mm, the outer diameter of the insulated cable 40 is allowed to be at least 0.35 mm. Taking the ratio of the two diameters, it can be said that the outer diameter of the thicker one is allowed to be at least about twice the outer diameter of the thinner one. Since the insulated cable 40 is used as a power cable, the larger the cross-sectional area of the central conductor 41 (the larger the diameter), the better. As a result of thickening the central conductor 41, the outer diameter of the insulated cable 40 may be larger than the outer diameter of the outer conductor 13 of the coaxial cable 11. As shown in FIG. 6, the outer diameter of the insulated cable 40 is allowed to be about twice as large as the outer diameter of the outer conductor 13 portion of the coaxial cable 11. If the outer diameter difference is up to 0.18 mm, the portion sandwiched between the ground bars 20 and 30 can be filled with the joining member 24 by adjusting the amount of the joining member (solder) 24. When the insulated cable 40 is thicker than the diameter of the outer conductor 13 portion of the coaxial cable 11, the insulated cable 40 may be disposed on both sides of the parallel coaxial cables 11. As a result, the coaxial cable 11 is disposed between the insulated cables 40 that are thicker than the coaxial cable 11.

Next, a method for manufacturing the cable harness 10 will be described.
First, all the

cables

11 and 40 constituting the cable harness 10 are arranged in parallel and held by a jig or an adhesive tape. For example, as shown in FIG. 1, the

cables

11 and 40 are arranged from the first center (upper end position in FIG. 1) to the third core, and the power insulation cable 40 is used. Is the signal coaxial cable 11. Further, the positions of the ends of all the

cables

11 and 40 are matched.

Then, the end portions of all the

cables

11 and 40 are subjected to the lead processing. This lead-out process is performed using a laser processing machine such as a YAG laser or a CO ₂ laser. First, the wavelength and intensity of the CO ₂ laser are adjusted, and the jacket 12 of the coaxial cable 11 is moved from the end to a predetermined position. Cut at a distance, and pull out the end to remove. When the CO ₂ laser is applied, it is retracted by bending a predetermined length from the end so as not to hit the insulated cable 40.

Next, by adjusting the wavelength and intensity of the YAG laser, the outer conductor 13 of the coaxial cable 11 is cut at a position closer to the end portion by a predetermined length from the jacket cutting position, and the outer conductor 13 on the end side is pulled out and removed. To do. At this time, the insulated cable 40 may or may not be retracted.

Further, by adjusting the wavelength and intensity of the CO ₂ laser, the inner insulator 14 of the coaxial cable 11 and the outer sheath 42 of the insulated cable 40 are further cut at a position closer to the end, and the inner insulator 14 on the end side and The outer cover 42 is pulled out and removed. Thus, since all the

cables

11 and 40 are processed together, a lead-out process can be performed efficiently.

Then, after performing the lead-out process, the outer conductor 13 and the jacket 42 are sandwiched between the ground bars 20 and 30 and positioned at a predetermined pitch, and the ground bars 20 and 30 and the outer conductor 13 and the jacket 42 are joined by the joining member 24. Fix it. When the joining member 24 is solder, the ground bars 20 and 30 are heated by pulse heat or the like, and the solder is thermally melted and fixed. Note that when ACF or NCF or the like is used instead of solder, the heating temperature is lower than that of soldering, so that the influence of heat on the insulating layer due to heating can be reduced.

It should be noted that the number and arrangement of various cables in the above embodiment are merely examples, and can be changed as appropriate.

In particular, if the diameter of the outer conductor 13 portion of the coaxial cable 11 and the outer diameter of the insulated cable 40 are substantially equal, both can be handled in terms of dimensions at locations fixed to the ground bars 20, 30. High degree of freedom.

The cable harness 10 of the above embodiment can take various forms such as a case where connectors are attached to both ends, a case where only one end is attached, and the other end is connected to a substrate. Next, a cable harness with a connector in which a connector is attached to the end of the cable harness 10 will be described.

In FIG. 7, the schematic plan view of the one end side of the cable harness with a connector is shown. FIG. 8 is a cross-sectional view taken along the arrow VII-VII in FIG.
As shown in FIGS. 7 and 8, in the cable harness with connector 50, the

central conductors

15 and 41 at the end of the cable harness 10 are independently connected to connection terminals 52 provided in the connector housing 51. ing. The

center conductors

15 and 41 can be connected to the connection terminal 52 by, for example, batch soldering by pulse heat. In FIG. 7, the ground bar 30, the shape of the connector housing, and the shell are not shown.

As shown in FIG. 8, in the terminal portion of the cable harness 10, the shell 53 is connected to the connector housing so as to cover the cables 11 and 40 (the coaxial cable 11 is shown in FIG. 8) placed on the connector housing 51. The shell 53 is electrically connected to the ground bar 30 via solder or ACF. The shell 53 and the ground bar 30 are connected to each other by, for example, providing an opening 53 a in a part of the shell 53 facing the ground bar 30 and covering the ground bar 30 with the shell 53. This can be done by introducing solder or ACF from the opening 53a and filling the space between the lower surface of the shell 53 and the upper surface of the ground bar 30 (reference numeral 54) and conducting mutual conductive bonding.

When the cable harness 50 with a connector configured in this way is connected to the receptacle, it is connected to the ground circuit in the vicinity of both ends in the longitudinal direction of the shell 53. When the shell 53 is connected to the ground circuit, the ground bars 20 and 30 of the outer conductor 13 of the coaxial cable 11 are grounded via the shell 53.

In the cable harness 10 before being connected to the connection terminal 52, all the

cables

11 and 40 constituting the cable harness 10 are aligned with high accuracy, and the outer conductor 13 of the coaxial cable 11 and the jacket 42 of the insulated cable 40 are arranged. Since it is sandwiched and fixed between the ground bars 20 and 30, the arrangement is not disturbed. Therefore, the cable harness 50 with a connector has each center conductor positioned with respect to each connection terminal 52 with high accuracy. In addition, as described above, the performance of the insulated cable 40 as a power cable is good.

A structure in which the cable harness 10 according to the present invention is connected to a connection terminal of an FPC or PWB is also possible. It can also be connected to the circuit of the device body via the FPC.

The example of the dimension of each cable in the cable harness 10 which concerns on this invention is shown.
(Example 1) When the coaxial cable 11 is an AWG 44 The outer diameter of the outer conductor 13 of the coaxial cable 11 is about 0.21 mm, and the outer diameter of the central conductor 15 of the coaxial cable 11 is about 0.06 mm. .
On the other hand, the insulated cable 40 is preferably AWG 44 or thicker than the AWG 44, and the jacket 42 is preferably 0.03 mm or more in thickness, so that the outer diameter of the insulated cable 40 is 0.12 mm. The above is preferable. Moreover, since the outer diameter of the insulated cable 40 may be 0.18 mm thicker than the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11, the outer diameter of the insulated cable 40 is allowed to be 0.39 mm. In this case, the outer diameter of the central conductor 41 of the insulated cable 40 is allowed to 0.33 mm. When the outer diameter of the insulated cable 40 is equivalent to that of the outer conductor of the coaxial cable 11 and the thickness of the jacket 42 is 0.03 mm, the outer diameter of the central conductor 41 of the insulated cable 40 can be 0.15 mm. The insulated cable 40 is thinner than the outer diameter of the outer conductor portion of the coaxial cable 11, but the difference is within 0.18 mm, so that it does not matter.

(Example 2) When the coaxial cable 11 is an AWG 46 The outer diameter of the outer conductor 13 of the coaxial cable 11 is about 0.17 mm, and the outer diameter of the central conductor 15 of the coaxial cable 11 is about 0.05 mm. .
On the other hand, the insulated cable 40 is preferably AWG 46 or thicker than the AWG 46, and the jacket 42 is preferably 0.03 mm or more in thickness, so that the outer diameter of the insulated cable 40 is 0.11 mm. The above is preferable. Moreover, since the outer diameter of the insulated cable 40 may be 0.18 mm thicker than the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11, the outer diameter of the insulated cable 40 is allowed to be 0.35 mm. In this case, the outer diameter of the central conductor 41 of the insulated cable 40 is allowed up to 0.29 mm. If the outer diameter of the insulated cable 40 is equivalent to that of the outer conductor of the coaxial cable 11 and the thickness of the jacket 42 is 0.03 mm, the outer diameter of the central conductor 41 of the insulated cable 40 can be 0.11 mm.

So far, we have explained an example in which each cable is sandwiched between a common ground bar and arranged in a row. However, each cable harness is divided into two or more terminals and each is sandwiched between a common ground bar. It may be arranged in two or more rows horizontally or vertically. Moreover, in parts other than a terminal part, each cable may be wound with a tape etc. and bundled.

Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
