The first embodiment exemplifies a mounting structure of a ROM 60 as an electrical component mounted on the wiring unit 10. Although not shown in detail, the wiring unit 10 is provided in an automatic transmission of an automobile and performs a part of control related to a shift operation.

As shown in FIG. 6, the wiring unit 10 includes a metal plate 11 formed by bending a metal plate material. The plate 11 has a flat electric wire holding surface 12 for holding a plurality of electric wires (not shown), and a flat sliding surface 13 for slidingly mounting the ROM 60 at a position different from the electric wire holding surface 12. . The electric wire holding surface 12 is configured to be elongated in the wiring direction of each electric wire. Each electric wire is bound by a binding band (not shown) and fixed to the plate 11.

The ROM 60 is a medium for storing data related to the speed change operation, and has a flat block shape having a rectangular shape in plan view as shown in FIG. In the case of the first embodiment, a commercially available ROM 60 is used. Although not shown in detail, one end of the electric wire is connected to the rear surface of the ROM 60 (the rear surface in the sliding direction described later).

As shown in FIG. 2, the sliding surface 13 of the plate 11 is provided on a plate body 14 having a rectangular shape in plan view corresponding to the ROM 60. The plate body 14 includes a front edge 15 along the left-right direction that defines the sliding surface 13 in front of the ROM 60 in the sliding direction, and a side edge 16 along the front-rear direction that defines the sliding surface 13 on the side in the sliding direction of the ROM 60. And a rear edge 17 along the left-right direction that defines the sliding surface 13 behind the ROM 60 in the sliding direction. The leading edge 15 and the trailing edge 17 are arranged in parallel to each other, and the side edges 16 are arranged in parallel to each other. In addition, the rear edge 17 is continuous with the side where the electric wire holding surface 12 is located via a connecting portion 18 that is bent downward from the rear edge 17 and continues.

As shown in FIG. 2, the plate 11 has a stopper portion 19 that bends and rises from the front edge 15 of the plate main body 14 and a pair of left and right guide portions 21 that bend and rise from both side edges 16 of the plate main body 14. ing. On the other hand, the plate 11 does not have a portion that bends and rises from the rear edge 17 of the plate body 14.

The stopper portion 19 has a rectangular shape when viewed from the front, and has a configuration in which the stopper body 19 is bent at a right-angle central portion of the front edge 15 of the plate body 14 and bent at a substantially right angle. Both guide portions 21 have a rectangular shape in a side view, and are disposed so as to be displaced from each other in the front-rear direction. One of the guide portions 21 is bent at a substantially right angle to a portion near the front edge 15 of the one side edge 16 of the plate body 14, and the other is a portion near the rear edge 17 of the other side edge 16 of the plate body 14. Are bent substantially at right angles to each other. The stopper portion 19 and both guide portions 21 have substantially the same rising dimensions, and are configured such that the height positions of the respective upper ends are aligned.

The plate 11 also includes a separation regulating portion 22 that protrudes inward from the upper ends of the stopper portion 19 and both guide portions 21 and an extension that continuously extends rearward from the upper rear ends of both guide portions 21. It has a protruding portion 23 and a return regulating main body portion 24 that bends inwardly from the extending end (rear end) of the extending portion 23 and projects. The extension part 23 and the return restriction main body part 24 constitute a return restriction part 25 of the present invention.

Each separation regulating portion 22 has a rectangular shape in plan view having the same plate width dimension as each of the corresponding stopper portion 19 and both guide portions 21, and is substantially parallel to the sliding surface 13 with the plate thickness direction facing up and down. It is arranged facing each other. The left and right separation regulating portions 22 bent from the upper ends of both guide portions 21 have a slightly larger overhanging dimension than the front separation regulating portions 22 bent from the upper ends of the stopper portions 19. The extending portion 23 has a rectangular shape in a side view that is long in the front-rear direction, and the plate surface is continuous with the plate surface of the guide portion 21 without a step, with the plate thickness direction facing left and right.

Both return regulating main body portions 24 have a rectangular shape in front view having the same plate width dimension as that of the extending portion 23, and the lower end thereof is disposed substantially parallel to the sliding surface 13 with the plate width direction facing up and down. The As shown in FIG. 3, the both return regulating main body 24 has a tapered shape in plan view so as to incline forward toward the tip (projecting end).

As shown in FIG. 2, the stopper portion 19 and the front side separation restricting portion 22 are formed by sequentially bending portions extending from the front edge 15 of the plate body 14 substantially at a right angle. Similarly, the guide portion 21 and the left and right side separation restriction portions 22 are formed by sequentially bending portions extending from the side edges 16 of the plate body 14 at substantially right angles. Further, the extension part 23 and the return regulation main body part 24 are formed by bending a part extending rearward of the guide part 21 at a right angle. Therefore, the stopper portion 19, the guide portion 21, the separation restriction portion 22, the extension portion 23, and the return restriction main body portion 24 are integrally formed by bending work continuously from the plate main body 14.

During assembly, the ROM 60 is pushed from the rear of the plate 11 toward the stopper portion 19. Then, the front surface (the front surface in the sliding direction) of the ROM 60 interferes with the both return restricting main body 24, and the both return restricting main body 24 is pressed by the ROM 60 and is expanded and deformed according to the taper shape. At this time, the extending portion 23 connected to the return-restricting main body portion 24 is elastically deformed with a portion near the guide portion 21 as a fulcrum. As shown in FIG. 4, when the push-in operation proceeds, the lower surface of the ROM 60 slides on the sliding surface 13 of the plate main body 14, and both side surfaces (surfaces on the side in the sliding direction) of the ROM 60 extend along the guide portions 21. And slidably guided. Further, the left and right separation control portions 22 are opposed to the upper surface of the ROM 60 and the lifting from the sliding surface 13 of the ROM 60 is restricted. In the sliding process of the ROM 60, the tip of the return restriction main body 24 interferes with both side surfaces of the ROM 60, and the extended portion 23 is elastically deformed.

As shown in FIGS. 1 and 5, when the ROM 60 reaches the proper assembly position, the entire lower surface of the ROM 60 is supported by being in contact with the sliding surface 13 of the plate body 14, and the front surface of the ROM 60 is supported by the stopper portion 19. It abuts and the further pushing of the ROM 60 is restricted. Further, when the ROM 60 reaches the proper assembly position, the leading ends of the two return regulating main body portions 24 are dissociated from both side surfaces of the ROM 60, the two extending portions 23 are elastically restored, and the leading ends of the two return regulating main body portions 24 are restored. Is arranged so as to be able to come into contact with the rear surface of the ROM 60, and the backward movement of the ROM 60 is restricted. Furthermore, in addition to the left and right side separation restricting portions 22, the front side separation restricting portion 22 is disposed on the upper surface of the ROM 60 so as to be able to face and come into contact therewith, so that the floating of the ROM 60 from the sliding surface 13 is reliably restricted. . Furthermore, both guide portions 21 are arranged so as to be able to face and come into contact with both side surfaces of the ROM 60, and the positional deviation of the ROM 60 to the left and right sides is restricted. Thus, the ROM 60 is attached to the plate 11 in a state in which displacement in the front-rear, upper- and left-right directions is restricted.

As described above, according to the first embodiment, the ROM 60 is attached and fixed to the plate 11 in the displacement restricted state by the stopper part 19, the guide part 21, the separation restriction part 22 and the return restriction part 25. At this time, it is only necessary to slide the ROM 60 on the sliding surface 13 of the plate 11, and the caulking process can be omitted. Therefore, the cost and man-hour required for the caulking process can be reduced.

Further, since the return restricting portion 25 is elastically deformable, the backward displacement of the ROM 60 can be restricted with a relatively simple structure.

Furthermore, since the guide part 21, the stopper part 19, the separation restricting part 22 and the return restricting part 25 are constituted by a plate-like part continuous from the plate main body 14, the ease of manufacturing can be ensured. Further, since it is not necessary to newly install a special structure for attaching to the plate 11 in the ROM 60, the structure of the ROM 60 is not complicated.

Furthermore, the plate 11 to which the ROM 60 is attached is mounted on the wiring unit 10 for the automatic transmission and has the electric wire holding surface 12 for holding the electric wires separately from the sliding surface 13, so that the sliding surface The number of parts can be reduced and the overall structure can be simplified as compared with the case where 13 and the electric wire holding surface 12 are provided on separate members.

<Example 2>
7 to 14 show a second embodiment of the present invention. Unlike the first embodiment, the second embodiment does not have portions that bend and rise from the front edge 15A and both side edges 16A of the plate body 14A, and the structure of the ROM 60A is also different from the first embodiment. Other parts are the same as those in the first embodiment. Although not shown, the connecting portion 18 is bent downward and connected to the rear edge 17A of the plate main body 14A in the same manner as in the first embodiment.

As shown in FIG. 8, the ROM 60 </ b> A includes a flat block-shaped ROM main body 61 that is rectangular in plan view, and a pair of left and right locking pieces 62 that protrude downward from the left and right ends of the lower surface of the ROM main body 61. Both locking pieces 62 are formed in an L-shaped plate shape when viewed from the front, and are substantially horizontally so as to approach each other from the lower end of the leg portion 63 on the distal end side and the leg portion 63 hanging from the lower surface of the ROM main body 61 on the proximal end side. It has the latching claw 64 which protrudes. The locking claw 64 has a rectangular shape when viewed from the bottom, and has a facing surface 65 that faces the lower surface of the ROM main body 61. As shown in FIGS. 12 to 14, the facing surface 65 of the locking claw 64 is configured to incline linearly so as to gradually approach the lower surface of the ROM main body 61 toward the rear in the sliding direction. As shown in FIGS. 9 to 11, the sliding direction of the ROM 60A of the second embodiment is defined as the direction around the rotation axis RC on the sliding surface 13A of the plate body 14A.

As shown in FIG. 7, the plate body 14A has a flat plate shape that is rectangular in plan view. One rotation axis RC is set at an appropriate position in the center of the plate body 14A.

The plate main body 14A has a slide groove 31 having a circular arc shape in a plan view along the circumferential direction around the rotation axis RC. The slide groove 31 is paired at a symmetrical position with the rotation axis RC in between, and penetrates the plate main body 14A at an angle range of approximately 90 degrees. At one end in the circumferential direction of both the slide grooves 31, an insertion port 32 having an extended groove width so that the locking piece 62 can be inserted is provided. Further, as shown in FIGS. 9 and 12, a pair of square protrusions is formed on the lower surface (back surface) of the plate body 14 </ b> A at a position near the other circumferential end of both slide grooves 31 and close to both slide grooves 31. 25A (return restricting portion) is provided.

Here, the ROM 60A is pulled down to the plate body 14A from above and is kept at the slide start position. As shown in FIG. 12, at the slide start position, the ROM main body 61 is supported by the sliding surface 13A of the plate main body 14A, the both locking pieces 62 are inserted through the both insertion openings 32, and the locking claws 64 are moved to the plate. It protrudes downward (back side) of the main body 14A. In this state, the ROM 60A is rotated around the rotation axis RC from the slide start position to the slide completion position. Then, the leg portion 63 slides on both side groove surfaces 21A (guide portions) of the slide groove 31, and the slide operation of the ROM 60A is guided. Further, as shown in FIG. 10, the locking claw 64 is arranged to face the opening edge 22A (separation regulating portion) of the slide groove 31 on the lower surface of the plate main body 14A, so that from the sliding surface 13A of the ROM 60A. Is lifted.

Immediately before the ROM 60A reaches the slide completion position, as shown in FIG. 13, the protrusion 25A enters the inside of the facing surface 65 of the locking claw 64, and further protrudes into the facing surface 65 of the locking claw 64 by a sliding operation. The portion 25A slides, and the locking piece 62 is slightly bent and deformed. When the ROM 60A reaches the slide completion position, the locking claw 64 moves over the protrusion 25A and the locking piece 62 returns elastically, and the rear surface of the locking claw 64 contacts the protrusion 25A as shown in FIG. It is arranged so that it can contact. As a result, the ROM 60A is restricted from being displaced in the direction of returning to the slide start position. Further, when the front surface of the leg portion 63 comes into contact with the groove surface 19A (stopper portion) on the other circumferential side end (back side) of the slide groove 31, further sliding operation of the ROM 60A is restricted. Further, the state in which the locking claw 64 is disposed to face the opening edge 22A of the slide groove 31 on the lower surface of the plate main body 14A is also maintained.

As described above, in the case of the second embodiment, the plate 11A is provided with the slide groove 31 along the slide direction, and the ROM 60A is bent from the leg 63 passing through the slide groove 31 and the tip of the leg 63. And the guide portion is constituted by the groove portions 21A on both sides of the slide groove 31 slidable with the leg portion 63, and the stopper portion is a slide that can come into contact with the leg portion 63 forward in the sliding direction. The back side of the groove 31 is constituted by the groove surface 19A, the separation regulating part is constituted by the opening edge 22A of the slide groove 31 facing the locking claw 64 on the back side of the plate 11A, and the return regulating part is formed on the back side of the plate 11A. It is constituted by a protrusion 25A that protrudes to the side and can come into contact with the locking claw 64 in the return direction of the ROM 60A. For this reason, the protrusion part for attaching ROM60A to plate 11A is not provided, and it can avoid that the structure of plate 11A is complicated and enlarges.

Further, since the locking piece 62 of the ROM 60A interferes with the protrusion 25A serving as the return restricting portion and elastically deforms, the return movement of the ROM 60A to the rear can be restricted with a relatively simple structure.
