Description

    The present invention relates to a wire processing structure wired inside an electronic device, and a television having the wire processing structure.

    A television for displaying and viewing a broadcasted video on a display (hereinafter simply referred to as a television) has been widely used in general households as a basic medium for viewing entertainment programs, movies, news, and the like. In recent years, digital television broadcasts have been started against the background of the advancement of semiconductor technology and electronic technology. Along with this, a digital tuner that can receive the digital television broadcasts has been provided, and signal processing has been digitized. On the other hand, digital televisions with many scanning lines are rapidly spreading.

    FIG. 11 shows an example of an internal circuit board mounting structure in a CRT digital television 1 that has been widely used.

    In the digital CRT television 1 shown in FIG. 11, a main board 2 is horizontally arranged below the back of a CRT display 1a that displays a predetermined video based on a digital video signal input from the outside. The main board 2 is a circuit board for performing various control processes such as video, audio, or power of the digital CRT television 1.

    The main board 2 is mounted with a digital tuner 3 that extracts and outputs a broadcast signal of a selected channel from a digital television broadcast signal received via an antenna (not shown). The digital tuner 3 has a substantially rectangular parallelepiped metal casing having, for example, a substantially rectangular lower surface and upper surface composed of short sides and long sides, and four leg portions 3a are provided in the vicinity of the four corners of the lower surface. The leg portions 3a are soldered at predetermined positions on the main board 2 so as to be vertically arranged on the main board 2.

    Further, the main board 2 includes a descrambling process for releasing the scramble of the digital TV broadcast signal output from the digital tuner 3, and a video signal and an audio signal from the multiplexed digital TV broadcast signal. In order to perform de-multiplex processing for extracting data signals, a sub-substrate 4 on which a plurality of processing IC chips (not shown) are mounted is vertically mounted with a structure to be described later.

    That is, a slot 5 is provided at a predetermined position of the main board 2, and a slot terminal 4a corresponding to the slot 5 is provided at the lower end of the sub board 4. The sub board 4 is a slot terminal. 4a is inserted into the slot 5 of the main board 2 to be vertically mounted.

    Also, an infrared light receiving board for receiving a control command transmitted by, for example, infrared rays from a remote controller (not shown) operating wirelessly for power on / off, channel selection, volume adjustment, and the like is provided in the vicinity of the main board. . The infrared light receiving substrate and the main substrate 2 are connected to each other by a wire 6, and control signals are transmitted and received between the two substrates.

    The wire 6 wired from the infrared light receiving substrate is placed on the main substrate 2 and, for example, a connector 7 provided at the tip is inserted into a connector mounted on the main substrate 2 to be connected by wiring. At this time, the wire 6 is fixed at a predetermined position on the substrate by, for example, a resin wire holder 8 so as not to move unnecessarily on the main substrate 2 and be damaged by contact with other components.

    The wire holder 8 has a structure in which, for example, a hole is formed in the end portion of the substrate, a band is inserted into the hole, and the periphery of the wire is circularly fastened with the band.

    However, in the wire holder 8 having such a structure, a new member has to be prepared separately, leading to an increase in cost. Further, there is a problem that workability for mounting the wire holder 8 on the substrate 2 is poor.

    In order to solve these problems, the following conventional techniques are disclosed.

    That is, in Patent Document 1, a substantially C-shaped wire holder is formed on a discarded substrate cut out from a printed circuit board. The wire holder is fixed with a screw so as to protrude from the end portion of the substrate, thereby fixing the wire.

    Further, in Patent Document 2, a holding tool having a substantially C-shaped holding portion for holding a wire is also used by effectively soldering a discarded plate portion of the substrate to a perforated wiring portion provided on the substrate by soldering. To fix the wire.

Further, in Patent Document 3, a fixing flat plate having leg portions formed with locking portions at both lower ends is manufactured on a lead wire that rises from the back surface to the upper surface through a through hole. Is inserted and slid into a substantially U-shaped through groove provided on the substrate so as to straddle the wire, and the lead wire is pressed onto the substrate and fixed.

    According to the configuration of Patent Document 1, since the wire holder is discarded and molded using the substrate, the cost is certainly reduced in that respect. However, in this structure, since the wire holder is fixed to the substrate using screws, there are problems that the assembling workability is poor and the cost is increased.

    Further, the position where the wire holder can be fixed to the substrate is limited to a state in which the wire holder protrudes from the end portion of the substrate, so that it is difficult to fix the wire holder to the optimal position on the substrate.

    According to the configuration of Patent Document 2, since the discard plate portion of the substrate is effectively used as the holder, the cost is surely reduced in that respect. However, in this structure, since solder is used to fix the holder to the substrate, the substrate must be perforated and wiring must be provided around it, leading to an increase in cost.

    Moreover, since it is necessary to perform soldering work, workability | operativity is bad. Furthermore, if the wire repeatedly vibrates or changes in temperature, stress is applied to the soldered portion, cracks may occur, and reliability may be impaired.

    According to the configuration of Patent Document 3, since the fixing flat plate material is manufactured by the surplus portion of the circuit board, it certainly leads to cost reduction. However, since the fixing flat plate material is fixed by sliding the inside of the through-groove and pressing the lead wire from above, the lead wire rising from the back surface to the top surface of the substrate as in this cited reference via the through-hole can be used. Can be fixed, but the above-described wire that is wired from the infrared light receiving substrate and fixed on the main substrate does not have a rising portion from the substrate, and such a fixing plate material can be fixed. Can not.

Optimal signal and sound from speaker 11g Controls treated to output state includes a voice processing section 11f, and a remote control receiver 11i for receiving a control command transmitted from the remote controller 11h.

    FIG. 2 shows a circuit board mounting structure inside the digital CRT television 11.

    As shown in the figure, the digital CRT television 11 has a main board 12 as a printed wiring board disposed horizontally below the back of the CRT display 11a. The main board 12 is a circuit board constituting the controller 11b for performing various control processes such as video, audio, or power of the digital CRT television 11.

    On the main board 12, the digital tuner 11c as a housing component is mounted. The digital tuner 11c has a metal casing 11c1 formed by bending, for example, an aluminum plate having a substantially rectangular parallelepiped shape having a substantially rectangular bottom surface and an upper surface, for example, having a short side and a long side, in the vicinity of the four corners of the bottom surface. Is provided with four leg portions 11c2. For example, the leg portion 11c2 is subjected to Sn plating, and the leg portion 11c2 is soldered to a predetermined position of the main substrate 12 so as to be vertically arranged on the main substrate.

    Further, the main board 12 includes a descrambling process for releasing the scramble of the digital TV broadcast signal output from the digital tuner 11c, and a video signal and an audio signal from the multiplexed digital TV broadcast signal. In addition, a sub-board 13 constituting the digital processing unit 11d, on which a processing IC (not shown) made into one chip is mounted for performing demultiplex processing for extracting data signals, is vertically mounted with a structure to be described later. The

    That is, a slot 14 is provided in parallel at a position adjacent to the position where the digital tuner 11c is erected on the main board 12, and the lower end of the sub board 13 corresponds to the slot 14. A convex slot terminal 13 a is provided, and the sub-board 13 is vertically mounted at a position adjacent to the digital tuner 11 c by inserting the slot terminal 13 a into the slot 14 of the main board 12.

    In addition, an infrared light receiving board (not shown) that receives a control command transmitted by, for example, infrared rays from a remote control (not shown) operated wirelessly for power on / off, channel selection, volume adjustment, etc. is provided in the vicinity of the main board. It has been. The infrared light receiving substrate is mounted with a light receiving element composed of, for example, a phototransistor or the like, and is connected to the main substrate 12 by a wire 16 so that a control signal based on a control command received by the light receiving element is sent to both substrates. Sent and received between.

    The wire 16 wired from the infrared light receiving substrate is placed on the main substrate 12 and, for example, a connector 17 provided at the tip is inserted into a connector mounted on the main substrate 12 to be connected. At this time, the wire 16 is fixed at a predetermined position on the substrate 12 via a spacer 17 described later so that the wire 16 does not move unnecessarily on the main substrate 12 and is not damaged by contact with other components.

    As shown in FIG. 3, the main board 12 before being assembled in the digital CRT television 11 has an unnecessary portion 19 (predetermined portion) in a substantially corner portion due to the wiring layout. In order to suspend the wire 16 on the substrate 12, for example, two spacers 17 that can be separated at the time of use are formed by die processing so as to be adjacent to each other. As shown in FIG. 4, each spacer 17 includes a holder portion 17a, a support portion 17b, and a locking portion 17c.

    That is, the holder portion 17a is formed in a substantially C shape having an open portion 17a1 having a width enough to allow the wire 16 to be inserted at an upper portion thereof and a horizontal portion 17a2 at a lower portion thereof. The opening portion 17a1 opens upward, and when the spacer 17 is erected on the main substrate 12, the wire 16 can be inserted into the ring of the holder portion 17a from above. The horizontal portion 17a2 is in contact with a rotation restricting protrusion 15 (described later) formed on the main substrate 12, and restricts the rotation direction of the spacer 17 when standing on the main substrate 12 to achieve a predetermined rotation. Functions to fix in position. That is, in this embodiment, the rotation restricting protrusion 15 and the horizontal portion 17a2 constitute a fixing mechanism.

    The support portion 17b is formed to extend downward from a position facing the opening portion 17a1 of the holder portion 17a so as to extend linearly by a length substantially the same as the substrate thickness of the main substrate 12, and the spacer 17 is formed as a main substrate. When erected on 12, it slides in a circular hole 18 b (described later) formed in the main board 12.

    The locking portion 17c is wider than the support portion 17b and is provided so as to be connected to the support portion 17b in a substantially inverted T shape, and when the spacer 17 is erected on the main substrate 12, The spacer 17 is engaged with the back surface to prevent the spacer 17 from coming off from a through hole 18b, which will be described later, of the main board 12. Further, the lower portion of the locking portion 17c is connected to the main substrate 12 through a perforation 17d so as to be separable when used.

    On the other hand, as shown in FIG. 5, at two predetermined places where the wire 16 of the main board 12 is suspended, a through hole 18 for standing the spacer 17 and a spacer 17 standing on the through hole 18 are provided. A rotation restricting protrusion 15 for restricting the rotation is formed.

    The through hole 18 has a rectangular hole 18a having a long side slightly larger than the width of the locking portion 17c of the spacer 17 and a short side slightly larger than the plate thickness of the locking portion, and a center of the rectangular hole 18a. The center of the spacer 17 is substantially coincident with the circular hole 18b having a diameter slightly larger than that of the support portion 17b of the spacer 17. That is, the locking portion 18c of the spacer 17 can be inserted into the square hole 18a, and the support portion 17b of the inserted spacer 17 can be rotated in the circular hole 18b.

    The rotation restricting projections 15 are formed by soldering, for example, the DIP method on four circular lands that are pattern-formed at positions to be described later. That is, the circular land is concentric with the circular hole 18b and has a diameter equal to or smaller than the length of the horizontal portion 17a2 of the holder portion 17a on a virtual circumference with the orthogonal line to the rectangular hole 18a interposed therebetween. A total of four patterns are formed on each side of the square hole 18a so as to face each other with a distance equal to or slightly larger than the thickness of the holder portion 17a.

    Next, when the digital CRT television 11 is assembled, the spacer 17, the through hole 18, and the rotation restricting protrusion 15 disposed on the main substrate 12 described above are used to connect the main substrate 12 and the infrared light receiving substrate. A configuration in which the wires 16 wired and connected in the above manner are suspended on the main board 12 will be described below.

    First, the two spacers 17 formed on the unnecessary portion 19 of the main substrate 12 are separated from the main substrate 12 main body by cutting the perforations 17d. Then, the locking portion 17 c of the spacer 17 is aligned with the rectangular hole 18 a of the through hole 18 provided in the main board 12 and inserted. As described above, the length of the long side and the short side of the rectangular hole 18a is slightly larger than the size of the corresponding locking portion 17c, so that the rectangular hole 18a can be smoothly inserted without rattling.

    The spacer 17 is inserted until the support portion 17b coincides with the plate thickness cross section of the main substrate 12, and is then rotated approximately 90 ° in the direction of the arrow A about the support portion 17b in the circular hole 18b. The At this time, as described above, the support portion 17b extends linearly by a length substantially the same as the substrate thickness of the main substrate 12, and the circular hole 18b has a slightly larger diameter than the support portion 17b. Since each of the locking portions 17c is formed, the upper end of the locking portion 17c can be smoothly rotated while being substantially in sliding contact with the back surface of the main substrate 12 and the horizontal portion 17a2 of the holder portion 17a with the surface of the main substrate 12, respectively. .

    When the spacer 17 is rotated, the horizontal portion 17a of the holder portion 17a eventually comes into contact with and interferes with the rotation restricting protrusions 15 formed in two pairs on both sides of the square hole 18a on the surface of the main board 12 respectively. To do. Here, the spacer 17 is further rotated so that both ends of the horizontal portion 17a2 get over only one of the corresponding pair of rotation restricting protrusions 15 and are sandwiched between the pair of rotation restricting protrusions 15 and 15, respectively.

    As described above, the pair of rotation restricting protrusions 15 are disposed so as to be opposed to each other by a distance equal to or slightly larger than the plate thickness of the horizontal portion 17a2, and thus are disposed between the pair. The horizontal portion 17a2 is restricted from interference by the rotation restricting projection 15 at 90 ° without rattling. Accordingly, the spacer 17 is easily and reliably erected and disposed without falling onto the main board 12 in a predetermined position and rotation direction.

    Thereafter, the wire 16 is inserted into the ring of the holder portion 17a of the spacer 17 erected on the main board 12 from above through the opening portion 17a1. As a result, the wire 16 is reliably and easily suspended and supported at a predetermined position on the main board 12.

    As described above, according to the configuration of this embodiment, the spacer 17 formed in the unnecessary portion 19 of the main substrate 12 is inserted and rotated into the through hole 18 provided at a predetermined position of the main substrate 12 to rotate the rotation restricting projection. Since the rotation direction is regulated and fixed at 15 and the wire 16 is suspended and supported by the spacer 17, wire processing for suspending the wire connected on the substrate at a predetermined position at low cost easily and reliably. It is possible to provide an excellent effect that a structure and a television to which the wire processing structure is applied can be provided.

  In addition, this invention is not limited to the structure of an Example, About the structure listed below, it can change suitably.

  1. In the embodiment, the case of a digital CRT television has been described as an example of the electronic device having the main board. However, the present invention is not limited to this, and includes televisions other than digital CRT televisions and household appliances other than televisions. You may make it apply to various board | substrates of various electric equipment.

    Also, the cable suspended on the board is not limited to the cable connected between the main board and the infrared light receiving board as in the embodiment, and can be applied to various cables wired in the electric equipment. is there.

  2. The opening provided in the holder portion of the spacer is not limited to a shape opening toward the upper side of the spacer, and may be provided at other positions as long as the wire inserted into the ring does not fall off. . For example, the upper part of the holder part, the side, the diagonally lower part, etc. are mentioned.

    The opening size of the opening is not particularly limited as long as the wire can be inserted and does not fall off.

  3. The shape of the holder portion of the spacer is not particularly limited as long as the wire can be inserted and does not fall off, and may be, for example, a substantially U shape other than the substantially C shape.

  4). The rotation restricting protrusion is not limited to the structure formed by soldering the land provided on the substrate as described in the embodiment, and the solder is provided at a predetermined position on the substrate that interferes with the horizontal portion of the spacer. You may make it arrange | position protrusion members other than. For example, a configuration in which a resin material is dropped onto a predetermined position and cured.

  5. The arrangement of the rotation restricting projections is not limited to the configuration in which the number of the two pairs is four as in the embodiment, and other arrangements may be used as long as the rotation direction of the spacer can be regulated and fixed. For example, as shown in FIG. 6, the pair of rotation restricting projections may be provided only on one side, not on both sides of the square hole.

    Alternatively, the rotation restricting protrusions are not paired, but pass through the center of the circular hole and are separated from the imaginary line orthogonal to the rectangular hole for restricting rotation by approximately ½ of the substrate thickness on the opposite rotation side. You may arrange | position at least 2 places so that the distance from the center of a circular hole may be located in the rotation locus circle of a horizontal part later mentioned. For example, an arrangement as shown in FIG.

  6). The rotation angle of the spacer regulated by the rotation regulating projection is not limited to 90 °, and can be appropriately changed to an angle suitable for suspending the wire. Of course, in that case, the arrangement position of the rotation restricting projection is changed so as to be the angle.

  7. The fixing mechanism provided between the substrate and the spacer inserted and rotated and locked in the through hole provided in the substrate and fixing the position in the rotation direction is provided on the main substrate as described in the embodiment. The configuration of the combination of the rotation restricting protrusion and the horizontal portion of the spacer that engages with the rotation restricting protrusion is not limited, and the rotation restricting protrusion may be provided on the spacer side and engaged with the substrate side.

    For example, at least one rotation restricting projection is formed not on the substrate side but on the lower part of the holder portion of the spacer, and at the corresponding surface position on the substrate side, a concave or penetrating engagement in which the projection is fitted and engaged. You may make it comprise by providing a joint hole. An example of this is a protrusion 17e shown in FIG.

    Alternatively, at least one rotation restricting projection is formed at the upper portion of the locking portion of the spacer, and a concave or penetrating engagement hole in which the projection is fitted is provided at a corresponding back surface position on the substrate side. You may make it comprise with. An example of this is a protrusion 17f shown in FIG.

  8). The shape of the through hole is not a simple circle instead of a circular hole combined with a square hole, but as shown in FIG. 10, the spacer is rotated by 90 ° so that the rotation position of the spacer can be regulated by the hole itself. Alternatively, the shape may be such that two substantially fan-shaped holes 18c formed by closing the remaining portion excluding the locus surface are combined.

    With such a substantially fan-shaped hole 18c, when the support portion of the inserted spacer is rotated, it is abutted against the fan-shaped hole 18c at a position of 90 ° and does not rotate any further.

    Even in this case, the rotational position is not limited to 90 °. In this case, it is needless to say that the central angle of the substantially sector-shaped hole is changed so that the angle can be regulated by the angle according to the rotational position.

  9. In the present embodiment, the substrate on which the cable is suspended has been described in the case where the spacer is formed in the unnecessary portion.
