  Now, when connecting an electronic device to a circuit board using a flexible cable as disclosed in Patent Document 1, an operator generally holds an intermediate position of the cable and inserts the cable terminal portion into the connector. However, in the flexible cable, the gap between the intermediate position held by the operator and the cable terminal portion at the tip is easily deformed due to the flexibility of the wiring portion. For this reason, since the position of the cable terminal portion is not fixed with respect to the intermediate position held by the operator, it becomes difficult to insert the cable terminal portion into the connector, and the connection workability is deteriorated.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic device with good workability of connecting an electronic device to a circuit board.

In order to achieve the above object, the invention described in claim 1 is a circuit board on which a connector is mounted, a flexible wiring part in which conductive wires are arranged, and a length projecting from the tip of the wiring part. A cable terminal part that electrically connects the conductor of the wiring part to the circuit board by being inserted into the connector, an opening formed at the leading end of the wiring part, and a fitting that protrudes from the leading end of the wiring part to both sides in the width direction A flexible cable, an electronic device that is attached to a base end opposite to the tip of the wiring portion and is electrically connected to the conductor of the wiring portion, and a first holding portion that holds the tip of the wiring portion A second holding portion that holds the electronic device, a groove portion that is formed on both sides in the width direction of the wiring portion in the first holding portion, and the fitting portion is slidably fitted along the length direction of the wiring portion, projecting the wiring portion side from the first bottom wall portion that forms one holding portion Comprising a fixed member having a projection extending through the mouth, a locking surface which is a connector-side in the protruding portion is formed so as to be substantially perpendicular to the first bottom wall portion, the protruding portion insertion surface of the locking surface and the opposite side is characterized Rukoto is formed to have an obtuse angle with respect to the first bottom wall portion at.

  According to this invention, in the flexible cable, the leading end of the wiring portion is held by the first holding portion of the fixing member. In addition, since the protrusion that protrudes from the first holding part to the wiring part side of the fixing member passes through the opening formed at the tip of the wiring part, the tip of the wiring part is longer than the first holding part The relative displacement in the direction and the width direction is restricted. Furthermore, since the fitting part which protrudes in the width direction both sides from the front-end | tip of a wiring part slide-fits to the groove part formed in the width direction both sides of the wiring part in the 1st holding part of a fixing member, On the other hand, the tip of the wiring part is restricted from relative displacement in the direction perpendicular to the length direction. Therefore, the position of the cable terminal portion protruding in the length direction from the tip of the wiring portion is determined with respect to the fixing member having the first holding portion, so that the operator holds the fixing member. Thus, the cable terminal portion can be easily inserted into the connector mounted on the circuit board. In addition, since the electronic device attached to the base end opposite to the distal end in the wiring portion of the flexible cable is held by the second holding portion of the fixing member, the cable terminal portion is inserted into the connector, and at the same time, The electrically connected conductors can also be electrically connected to the circuit board. According to the above, the connection workability of the electronic device to the circuit board using the flexible cable can be improved.

  When the operator grips the fixing member and inserts the cable terminal portion into the connector, the insertion force applied to the fixing member may damage the wiring portion at the periphery of the opening portion through the protruding portion that penetrates the opening portion. is there. However, in the invention described in claim 2, since the reinforcing portion for reinforcing the wiring portion is provided at the periphery of the opening, damage to the wiring portion when the cable terminal portion is inserted can be suppressed. As a result, the operator can insert the cable terminal portion into the connector without being aware of the strength of the insertion force, so that the connection workability can be improved.

  According to a third aspect of the present invention, the reinforcing portion and the fitting portion are integrally formed, and an elastically deformable plate having rigidity higher than that of the wiring portion is provided. And a projection part penetrates an opening part and a locking mouth part, and locks a locking mouth part. According to the present invention, the plate is restored together with the flexible wiring portion after the fitting portions on both sides in the width direction of the wiring portion are slide-fitted into the groove portions while being elastically deformed in the protruding direction of the protruding portion. Thus, the protruding portion penetrates into the locking opening that opens in the reinforcing portion. Therefore, improvement in connection workability is realized. In addition, according to the plate that integrally forms the reinforcing portion and the fitting portion, the tip of the wiring portion in the flexible cable can be easily held in the first holding portion of the fixing member, so that the connection work is also performed An improvement in performance can be realized.

  Further, the protruding portion of the fixing member passes through the opening portion and the locking port portion of the wiring portion, and locks the locking port portion that opens in the reinforcing portion of the plate. In addition, the fitting portion of the plate slides into the groove portion of the fixing member. As a result, the insertion force applied by the operator to the fixing member acts on the plate that integrally forms the reinforcing portion and the fitting portion via the protruding portion and the groove portion. However, since the periphery of the opening of the wiring part is reinforced by a reinforcing part formed by a plate having higher rigidity than the wiring part, the insertion force acting on the wiring part is reduced, and the wiring when inserting the cable terminal part is reduced. Damage to the part can be suppressed. As a result, the operator can insert the cable terminal portion into the connector without being aware of the strength of the insertion force, so that the connection workability can be improved.

  According to a fourth aspect of the present invention, the conducting wire is arranged so as to bypass the opening along the periphery of the opening. According to this invention, even if the insertion force applied to the fixing member by the operator acts on the wiring portion at the periphery of the opening via the protrusion that penetrates the opening, the opening is bypassed along the periphery of the opening. The conducting wire is less likely to receive a load. Therefore, disconnection of the conducting wire due to insertion of the cable terminal portion can be suppressed. As a result, the operator can insert the cable terminal portion into the connector without being aware of the strength of the insertion force, so that the connection workability can be improved.

  In the invention according to claim 5, the connector contacts the first holding portion as the cable terminal portion is inserted into the connector, and the connector terminal portion is electrically connected to the inserted cable terminal portion. And a pressing member that presses the cable terminal portion against the connector terminal portion. According to this invention, when the operator holds the fixing member and inserts the cable terminal portion into the connector, the first holding portion comes into contact with the pressing member of the connector, so that the pressing member becomes the connector terminal portion of the connector. Move to the side. As a result, since the cable terminal portion is pressed against the connector terminal portion by the pressing member and becomes conductive, the electrical connection state between the cable terminal portion and the connector terminal portion can be reliably obtained. Therefore, the electronic device can be reliably connected to the circuit board in spite of an easy insertion operation.

  The invention according to claim 6 includes a case member that accommodates the circuit board, and the fixing member is fixed to the case member. According to the present invention, by fixing the fixing member to the case member that accommodates the circuit board, the electronic device held by the second holding portion of the fixing member is electrically connected to the circuit board. It is possible to mechanically connect to the case member. According to the connection of such an electronic device, work man-hours can be reduced and connection workability can be improved.

According to this invention, since the wiring portion has flexibility, when the cable terminal portion is inserted into the connector, the cable terminal portion protruding from the distal end of the wiring portion contacts the display device attached to the proximal end of the wiring portion. As a result, there is a concern of causing wrinkles in the display device. However, since the second holding portion holds the display device at the proximal end of the wiring portion and the first holding portion holds the distal end of the wiring portion in the fixing member, the cable terminal portion can be prevented from coming into contact with the display device during insertion. . Therefore, the present invention is particularly suitable for an electronic device in which a display device that may cause a problem even if the function is not impaired is provided as the electronic device.

(Characteristic part)
Hereinafter, the characteristic part of the combination meter 100 by one Embodiment of this invention is demonstrated.

  As shown in FIGS. 2 to 4, the wiring portion 51 of the FPC 50 is provided with an opening 55 and a plate 57 at the tip 51 e. The opening 55 is provided at the center position in the width direction of the tip 51 e of the wiring part 51, and the wiring pattern 51 b formed in the wiring part 51 is arranged so as to bypass the opening 55. Therefore, a region where the wiring pattern 51b is not exposed is formed on the opposite side of the base end 51f across the opening 55 in the cable terminal portion 53.

  The plate 57 is made of, for example, a resin plate of about 0.4 mm, has higher rigidity than the wiring portion 51, and can be elastically deformed. The plate 57 is attached to the tip 51 e of the wiring part 51 along the film 51 a on the surface side of the wiring part 51. The plate 57 integrally forms a reinforcing portion 57b and a fitting portion 57c, and forms a locking port portion 57a and a biasing portion 57d. The reinforcing portion 57 b is located at the center portion in the width direction of the plate 57. The locking port portion 57 a is open to the reinforcing portion 57 b and is formed to overlap the opening portion 55 in a state where the plate 57 is attached to the wiring portion 51. The locking port portion 57a of the present embodiment is formed to be slightly smaller than the opening 55. The reinforcing part 57 b reinforces the wiring part 51 at the corresponding part by overlapping with the opening peripheral edge 55 a of the wiring part 51. A pair of fitting portions 57 c protrudes on both sides in the width direction of the tip 51 e of the wiring portion 51. The urging portion 57 d is located on the surface side of the cable terminal portion 53. The urging portion 57d can equalize the load acting from the side opposite to the cable terminal portion 53 due to the rigidity of the plate 57, and can urge the cable terminal portion 53 toward the connector terminal portion 73a.

  The first holding portion 61 of the fixing member 60 forms a protrusion 63, a groove 62, and a contact portion 61c in addition to the first bottom wall portion 61a and the first side wall portion 61b. As shown in FIG. 2, the protruding portion 63 protrudes from the first bottom wall portion 61 a to the wiring portion 51 side held by the first holding portion 61. The protrusion 63 passes through the opening 55 of the wiring portion 51 and the locking port 57a of the plate 57, and locks the locking port 57a. The locking surface 63a on the connector 73 side of the protrusion 63 is formed to be perpendicular to the first bottom wall portion 61a, and the insertion surface 63b opposite to the locking surface 63a is the first bottom wall portion 61a. Is formed to have an obtuse angle. The groove portions 62 are respectively formed along the length direction of the wiring portion 51 on the first side wall portions 61 b located on both sides in the width direction of the wiring portion 51 held by the first holding portion 61. In each of the groove portions 62, fitting portions 57c on both sides of the plate 57 are slidably fitted. The contact portion 61 c is a front end surface of each first side wall portion 61 b and contacts the slider 75 of the connector 73.

  A connection work method for connecting the liquid crystal panel 40 to the circuit board 70 in the present embodiment described above will be described below.

  First, the operator holds the gripped liquid crystal panel 40 from the side opposite to the wiring portion 51 of the FPC 50 to the holding claw 66 c of the fixing member 60, and the second bottom of the fixing member 60 from the front side. Press toward the wall 66a. As a result, the liquid crystal panel 40 is held by the second holding portion 66.

  Next, the operator elastically deforms the distal end 51 e of the flexible wiring portion 51 in the FPC 50 together with the elastically deformable plate 57 in the protruding direction of the protruding portion 63 of the fixing member 60. Further, the operator can connect each fitting portion 57c protruding from the wiring portion 51 to both sides in the width direction in the FPC 50 from the front side of the liquid crystal panel 40 while elastically deforming the wiring portion 51 and the plate 57. Slide fit into the groove 62. At this time, the leading end 51e of the wiring portion 51 can easily straddle the protruding portion 63 by the insertion surface 63b of the protruding portion 63 that forms an obtuse angle with respect to the first bottom wall portion 61a of the fixing member 60. Then, after the above, the operator restores the wiring portion 51 and the plate 57 at a position where the protruding portion 63 penetrates the opening portion 55 and the locking port portion 57a of the FPC 50, and makes the perpendicular to the first bottom wall portion 61a. The locking mouth portion 57a on the small edge side is locked by the locking surface 63a of the protruding portion 63 formed. As a result, the tip 51 e of the wiring part 51 is held by the first holding part 61.

  Thus, by holding the tip 51e of the wiring part 51 in the first holding part 61, the position of the cable terminal part 53 protruding in the length direction from the tip 51e of the wiring part 51 in the FPC 50 is the first holding part. The fixing member 60 having 61 is defined. Therefore, the operator can hold the fixing member 60 and insert the cable terminal portion 53 of the FPC 50 into the insertion port 73 b of the connector 73 mounted on the circuit board 70. Here, when the operator inserts the cable terminal portion 53 into the connector 73, the contact portion 61 c on the opposite side of the first holding portion 61 of the fixing member 60 from the second holding portion 66 is used as the slider 75 of the connector 73. Abut. Further, the operator continues to insert the cable terminal portion 53 into the connector 73 and moves the slider 75 to the connector terminal portion 73a side of the connector 73 by the contact portion 61c. As a result, the cable terminal portion 53 is pressed against the connector terminal portion 73a by the slider 75 via the urging portion 57d, and is electrically connected to the connector terminal portion 73a.

  In the present embodiment described so far, the protrusion 63 penetrates the opening 55 and the locking port 57a and locks the locking port 57a. The relative displacement of the tip 51e of the wiring part 51 with respect to the one holding part 61 can be restricted. Furthermore, by slidingly fitting each fitting portion 57c to each groove portion 62, the direction perpendicular to the length direction of the wiring portion 51 (that is, in the present embodiment, the width direction of the wiring portion 51 and the protruding direction of the protruding portion 63). The relative displacement of the tip 51e of the wiring part 51 with respect to the first holding part 61 can be restricted. According to these, since the tip 51e of the wiring portion 51 is easily and reliably held by the first holding portion 61, the position of the cable terminal portion 53 protruding from the tip 51e of the wiring portion 51 is the first holding position. The fixing member 60 having the part 61 is determined. Therefore, the operator can easily insert the cable terminal portion 53 of the FPC 50 into the connector 73 mounted on the circuit board 70 by holding the fixing member 60. In addition, since the liquid crystal panel 40 attached to the base end 51f of the FPC 50 is held by the second holding portion 66, the wiring pattern electrically connected to the liquid crystal panel 40 at the same time as the cable terminal portion 53 is inserted into the connector 73. 51 b can also be electrically connected to the circuit board 70. According to the above, the workability of connecting the liquid crystal panel 40 to the circuit board 70 by the FPC 50 can be improved.

  Here, in the present embodiment, the insertion force applied to the fixing member 60 when the cable terminal portion 53 is inserted into the connector 73 is connected to the wiring portion 51 on the peripheral edge 55a of the opening portion 55 via the projection portion 63 penetrating the opening portion 55. There is a concern that the wiring part 51 may be damaged if it is acted upon. When the wiring part 51 is damaged, problems such as disconnection of the wiring pattern 51b are caused. However, in the present embodiment, the protrusion 63 of the fixing member 60 locks the locking opening 57 a that opens to the reinforcing portion 57 b of the plate 57, and the grooves 62 of the fixing member 60 are fitted on both sides of the plate 57. The portions 57c are slidably fitted. As a result, the insertion force applied to the fixing member 60 by the operator acts on the plate 57 that integrally forms the reinforcing portion 57b and the fitting portion 57c via the protrusion 63 and each groove 62. However, since the opening peripheral edge 55a of the wiring part 51 is reinforced by the reinforcing part 57b formed by the plate 57 having higher rigidity than the wiring part 51, the insertion force acting on the wiring part 51 is reduced, and the cable terminal part. It is possible to suppress damage to the wiring part 51 when 53 is inserted.

  Furthermore, in this embodiment, even if the insertion force applied to the fixing member 60 acts on the wiring part 51 on the opening peripheral edge 55a via the protrusion 63, the wiring pattern 51b of the wiring part 51 that bypasses the opening 55 is provided. Has the effect of being less susceptible to load. According to the above, since the damage of the wiring part 51 resulting from the insertion of the cable terminal part 53 into the connector 73 is suppressed, the operator inserts the cable terminal part 53 without being aware of the strength of the insertion force. Thus, the connection workability can be improved.

  In addition, in the present embodiment, since the wiring part 51 has flexibility, the cable terminal part 53 protruding from the tip 51e of the wiring part 51 is the base of the wiring part 51 when the cable terminal part 53 is inserted into the connector 73. There is a concern that the liquid crystal panel 40 attached to the end 51f may come into contact with the panel 40 to cause wrinkles. However, in this embodiment, the liquid crystal panel 40 at the base end 51f of the wiring part 51 is held by the second holding part 66 and the tip 51e of the wiring part 51 is held by the first holding part 61. It can avoid that the terminal part 53 contacts the liquid crystal panel 40. Therefore, this embodiment can be said to be particularly suitable for the combination meter 100 provided with the liquid crystal panel 40 as a display device that may cause a problem even if the function is not impaired.

  In addition, in the present embodiment, as the cable terminal portion 53 is inserted into the connector 73, the cable terminal portion 53 is pressed against the connector terminal portion 73a by the slider 75. Moreover, since the urging portion 57d provided on the surface side of the cable terminal portion 53 can equalize the pressing force by the slider 75, the cable terminal portion 53 is equally urged by the connector terminal portion 73a. . Therefore, despite the easy insertion operation of the cable terminal portion 53, the electrical connection state between the cable terminal portion 53 and the connector terminal portion 73a can be reliably obtained.

  In addition, in this embodiment, the fixing portion 69 of the fixing member 60 is fixed to the fixing claw 23c of the internal structural member 23b by an operation in the same direction as the operation of inserting the cable terminal portion 53 positioned with respect to the fixing member 60 into the connector 73. It is possible to assemble to. Therefore, the liquid crystal panel 40 held by the second holding portion 66 of the fixing member 60 can be electrically connected to the circuit board 70 and simultaneously mechanically connected to the internal structural member 23b. According to such connection of the liquid crystal panel 40, the work man-hours can be reduced and the connection workability can be improved.
