In the display module 51, the movement of the printed circuit board 52 to the rear side is restricted by the front surface of the return shelf 3b3c in the substrate abutting portion 3b3.
Further, the upper end of the printed circuit board 52 abuts against the wall 3b3b, and the upward movement is restricted and the upper side is positioned.

Panel body abutting portion 3b4 is formed as a wall piece that rises forward from end portion 3bt.
The upper surface of the display panel body 1 comes into contact with the lower surface of the panel body abutting portion 3b4, and the upward movement of the display panel body 1 and the cushion 2 is restricted.

  In the assembled display module 51 shown in FIGS. 1 to 3, the front cover portion 3a and the rear cover portion 3b are parallel to each other (arranged in parallel), and the engaging protrusions 3b1 and 3b2 are the front cover. It is maintained by engaging with the long holes 3a2d and 3a3d of the portion 3a.

In this state, the display panel body 1 and the cushion 2 are held between the front cover portion 3a and the rear cover portion 3b with the cushion 2 being slightly crushed.
That is, the display panel body 1 urges the front cover portion 3 a by the elastic repulsive force of the cushion 2, and is held between the front cover portion 3 a and the rear cover portion 3 b together with the cushion 2 in the front-rear direction.

A wiring pattern 52c serving as a ground is provided in the vicinity of the periphery of the holes 52a and 52b.

  Next, the assembly operation of the display module 51 described above will be described with reference mainly to FIGS.

For the assembly work of the display module 51, the display panel body 1, the cushion 2, the shield case intermediate processed body 3t (hereinafter, intermediate processed body 3t), and the printed circuit board 52 are supplied.
The shield case 3 in the finished product of the display module 51 is supplied from the shield case forming process to the assembling process as an intermediate processed body 3t in an intermediate processed state.

Specifically, the shield case 3 is subjected to a press process in which a metal plate material such as stainless steel is punched into a predetermined shape in the forming process, and in the next bending process, the bending process with the connecting portion 3c side as a fulcrum is performed halfway. The intermediate processed body 3t is supplied to the assembly site.
That is, the intermediate processed body 3t is a shield case for assembling the display module 51.

  Specifically, as shown in FIG. 4, the state of the intermediate processed body 3t is the bending of the engaging arm portions 3a2 and 3a3, the fixing arm portions 3a4 and 3a5, the substrate abutting portion 3b3, and the panel body abutting portion 3b4. The processing is completed, and the bending processing with the connecting portion 3c side as a fulcrum is performed halfway.

The bending process of the connecting portion 3c that is performed halfway will be described in detail.
The intermediate processed body 3t is a punched intermediate body in which the front cover portion 3a and the rear cover portion 3b are connected in a flat plate shape via the connecting portion 3c in a state where the press work before bending is completed ( (See two-dot chain line LN2 in FIG. 4).

This flat punched intermediate body is bent with the connecting portion 3c side as a fulcrum as indicated by an arrow DR3 in FIG.
Specifically, the connecting portion 3c or both ends of the connecting portion 3c are bent as main fulcrums, but this bending stops when the angle formed by the front cover portion 3a and the rear cover portion 3b becomes a predetermined angle θa.

The predetermined angle θa is set at an angle of at least less than 90 °. Moreover, it sets with the angle which engagement arm part 3a2, 3a3 and the rear cover part 3b space apart.
In a state where the bending is stopped at the angle θa, the front cover portion 3a and the rear cover portion 3b are in a non-parallel facing posture in which the connecting portion 3c side is narrow and the distal end side is widened at the angle θa.

  More preferably, the angle θa is set as an angle at which the display panel body 1 and the cushion 2 can be inserted as if inserted between the front cover portion 3a and the rear cover portion 3b. For example, it is 7 ° to 10 °.

In assembling the display module 51, the operator first places the display panel body 1 and the cushion 2 between the front cover portion 3a and the rear cover portion 3b of the intermediate processed body 3t opened by the angle θa. 1 is set to the front cover portion 3a side, and the display screen 1a is inserted in a posture facing the opening 3a1 (FIG. 4: operation A1).
The operator inserts the display panel body 1 until it comes into contact with the connecting portion 3c.

Next, as shown in FIG. 5A, the operator opens the engaging arm 3a2 and the engaging arm 3a3 (not shown in FIG. 5) outward with a finger or a jig. (Arrow DR4).
Then, the front cover part 3a and the rear cover part 3b are bent with the connecting part 3c side as a fulcrum in the direction of decreasing the angle θa, and the rear cover part 3b is inserted between the base parts 3a2a and 3a3a (arrow DR5).

  The deformation of the engaging arm portions 3a2 and 3a3 that occurs at this time is elastic deformation, and the bent portion P is mainly used as the starting point of bending.

  When the engaging protrusions 3b1 and 3b2 come into contact with the bases 3a2a and 3a3a, the opening operation of the engaging arm portions 3a2 and 3a3 with a finger or a jig can be released.

  When the rear cover 3b is bent by the operator and reaches the position where the rear cover 3b enters the front cover 3a between the bases 3a2a and 3a3a to some extent and is spaced apart and parallel to each other, the cushion 2 is slightly crushed. Further, the engagement protrusions 3b1 and 3b2 of the rear cover portion 3b engage with the long holes 3a2d and 3a3d formed in the base portions 3a2a and 3a3a of the front cover portion 3a.

  By this engagement, the engaging arm portions 3a2 and 3a3 are automatically returned to the natural state (arrow DR6). The shield case 3t becomes the shield case 3 in a completed state. This state is shown in FIG.

In the holding state by the shield case 3, the display panel body 1 is pressed against the front cover portion 3a by the elastic repulsive force of the cushion 2, and is sandwiched and held in the front-rear direction without causing a displacement movement due to the frictional force generated by the pressing. Is done.
Even if an unintended shift movement occurs, a small amount of movement is caused by the panel body abutting portion 3b4 on the upper side, the engaging arm portions 3a2 and 3a3 on the left and right sides, and the connecting portion 3c on the lower side. Therefore, there is no problem in use.

When the operator sandwiches and holds the display panel body 1 and the cushion 2 by deformation from the intermediate processed body 3t to the shield case 3, the printed circuit board 52 is attached next.
Specifically, as shown in FIG. 6A, the upper end portion of the printed circuit board 52 is deformed so that the engaging arm portions 3a2 and 3a3 are opened outward by the left and right edges (arrow DR7). Then, the rear cover portion 3b is pushed in (arrow DR8).
The engaging arm portions 3a2 and 3a3 are formed such that the distal end portions of the bent portions 3a2c and 3a3c on the distal end side have an outward opening shape, and the dimensions are such that the left and right end portions of the printed circuit board 52 are in contact with the outward opening portion. Since it is set, the engaging arm portions 3a2 and 3a3 are naturally elastically deformed so as to open outward by the entry of the printed circuit board 52.

The elastic deformation of the engaging arm portions 3a2 and 3a3 is a deformation that opens outward from the bent portion P as a whole, including deformation starting from the bent portions P1 and P2.
The shapes and dimensions of the engaging arm portions 3a2 and 3a3 and the engaging projection portions 3b1 and 3b2 are related even when the engaging arm portions 3a2 and 3a3 are bent outwardly by the entry of the printed circuit board 52 and opened. The mating protrusions 3b1 and 3b2 are set so as not to disengage the elongated holes 3a2d and 3a3d.
Therefore, the engagement between the engagement protrusions 3b1 and 3b2 and the long holes 3a2d and 3a3d performed earlier is maintained without being released even if the printed board 52 is attached later.

When the approach of the printed circuit board 52 is advanced to some extent and passes through the top portion T1 of the bent portions 3a2c, 3a3c, which are the inwardly convex portions, the engaging arm portions 3a2, 3a3 are indicated by an arrow DR9 in FIG. 6 (b). To return to the natural state.
That is, the printed circuit board 52 is urged and guided by the bent portions 3a2c and 3a3c at positions where the printed circuit boards 52 are in contact with the shelves 3a2b and 3a3b, and is held between the contact positions in the width direction (left and right direction).
In other words, the bent portions 3a2c and 3a3c function as a substrate engaging portion that engages and holds the printed circuit board 52.
This held state is shown in FIG. 6 (b).

  In this way, the assembly of the display module 51 holding both the display panel body 1 and the cushion 2 and the printed board 52 is completed with the shield case 3.

As described above in detail, the display module 51 has a structure in which the display panel body 1 is covered with one shield case 3 so as to be sandwiched from both the front and rear surfaces.
Therefore, the mold cost and parts management cost of the shield case 3 are kept low.

Further, the shield case 3 is not a completed body in which the front cover part 3a and the rear cover part 3b are parallel to each other by bending at the connecting part 3c, but before the front cover part becomes the completed body. 3a and the rear cover part 3b are supplied to work as an intermediate processed body 3t having an angle θa of less than 90 °.
As a result, the operator inserts the display panel body 1 between the front cover portion 3a and the rear cover portion 3b that are connected in a non-parallel state in which the front end side extends at the connecting portion 3c, and the front cover portion 3a and the rear cover portion are inserted. The assembling work for holding the display panel body 1 by the shield case 3 is completed by bending the angle θa at a parallel facing posture with the 3b apart and engaging the engaging protrusions 3b1 and 3b2 with the long holes 3a2d and 3a3d. .

Therefore, the operator can perform the bending operation of the shield case 3 with the minimum necessary man-hours. In this bending operation, it is not necessary to position the front cover portion 3a and the rear cover portion 3b with high accuracy, and positioning is performed by simply bending.
Therefore, the assembly operation of the display module 51 is easy.

As described above, the holes 52a and 52b of the printed board 52 and the through holes 3a4a and 3a4a in the fixing arm portions 3a4 and 3a5 of the shield case 3 at the position where the upper end of the printed board 52 is brought into contact with the board abutting portion 3b3. 3a5a are located substantially concentrically.
Therefore, the operator inserts the shaft portions of the male screws NJ and NJ into the through holes 3a4a and 3a5a of the shield case 3 and the holes 52a and 52b of the printed circuit board 52 and screws them into the female screw portions provided in the chassis 53, thereby screwing them. Conclude.
Thereby, the display module 51 is attached to an electronic device such as a portable wireless device including the chassis 53.

In this screw fastening, the wiring pattern 52c serving as the ground formed around the holes 52a and 52b of the printed circuit board 52, the shield case 3 and the chassis 53 are electrically connected at the ground level only by fastening with a pair of screws NJ. Connected to.
Therefore, variation in ground potential is small, and electrical performance including unnecessary radiation performance is stabilized.

  The embodiment described in detail above is not limited to the above-described configuration and procedure, and may be modified without departing from the gist of the present invention.

The cushion 2 is for biasing the display panel body 1 against the front cover portion 3a of the shield case 3 so as not to be displaced.
Therefore, the cushion 2 can be replaced with a member or a structure that urges the display panel body 1.
For example, a rising piece that can be elastically deformed in the undulation direction by cutting and raising is formed in a part of the rear cover portion 3b, and the back surface of the display panel body 1 may be urged by the rising piece.

  The concavo-convex relationship of the concavo-convex engaging portion KB may be reversed. That is, a protrusion may be provided on the engagement arm portions 3a2 and 3a3 side, and a recess into which the protrusion enters may be formed on the rear cover portion 3b side. The recesses in this case can be formed by forming side walls bent in the front-rear direction on the left and right edges of the rear cover portion 3b and providing the side walls.
