This facilitates the alignment operation between the lock pin insertion hole 52 of the cover body 50 and the lock pin insertion hole 924 of the engaging portion 92 of the sealed member 90.

  Finally, the circuit board 70 is sealed while being sandwiched between the frame body 4 and the cover body 50 by engaging the lock pin 100 with the engaging portion 92 of the sealed member 90. Specifically, the lock pin insertion hole 52 of the cover body 50 and the lock pin insertion hole 924 of the engagement portion 92 of the sealed member 90 are inserted in this order while pushing the shaft portion 102 of the lock pin 100. At this time, the shade 103 of the shaft portion 102 is reduced in diameter by a pressing resistance against the lock pin 100 generated when passing through the lock pin insertion holes 52 and 924, and the lock pin insertion hole on the sealed member 90 side is reduced. When it passes through 924, it is released from the pushing resistance against the lock pin 100, and its blade piece expands. Then, the free end surface of the shade 103 is engaged with the inner surface of the top plate 921 of the engagement portion 92 in the engagement space defined between the circuit board 70 and the engagement portion 92. Thus, when the lock pin 100 is engaged with the sealed member 90, both the fitting recess 53 on the cover body 50 side and the engaging portion 92 on the sealed member 90 side are fitted as described above. Both the lock pin insertion hole 52 on the cover body 50 side and the lock pin insertion hole 924 on the sealed member 90 side are already positioned. Therefore, the engagement operation of both the lock pin 100 and the sealed member 90 can be easily performed.

  Through the above steps, the sealing operation of the circuit board 70 is completed in the state shown in FIGS.

[Action / Effect]
According to the first embodiment, the following operations and effects are achieved.

Since the lock pin 100 as a sealing member is engaged with the engaging portion 92 of the soldered sealing member 90, the circuit board 70 and the cover body 50 cannot be separated. Therefore, the connector 60 mounted on the circuit board 70 together with the indicators 14 to 16 cannot be approached from outside the machine. As a result, it is possible to prevent an illegal act on the control unit connected to the connector 60. In addition, since it is not necessary to make any particular changes to the assembly method, the conventional design can be fully utilized.

  (2) Since the screw insertion hole 911 is formed in the base 91 of the sealed member 90 and the frame body 4 and the circuit board 70 are screwed together by the screw 300 inserted into the screw insertion hole 911, the frame body 4 And the fixing force with respect to the circuit board 70 sandwiched between both of the cover bodies 50 is further enhanced.

<Embodiment 2>
Referring to FIG. 14, the second embodiment is characterized in that circuit board 70 is sealed using a binding band 500 as a sealing member and a metal fitting having a substantially L-shaped side surface as sealing member 600. The other configurations are substantially the same as those of the first embodiment.

  The binding band 500 is an insulok-type band for fastening the cover body 50 and the circuit board 70 together, and is an integrally molded product made of synthetic resin such as plastic. The binding band 500 includes a longitudinal band body 501 having flexibility, a cylindrical insertion portion 502 into which the band body 501 is inserted, and the like. When the band body 501 having a loop formed in the insertion portion 502 is inserted, The band body 501 is configured to be coupled so as not to come off.

  Although not specifically shown, the band body 501 has a serrated engaging claw group in a predetermined region on the main surface thereof. On the other hand, although the insertion portion 502 is not particularly illustrated, a connection mechanism such as an engaging claw for preventing the band body 501 inserted into the insertion portion 502 from being pulled out is provided therein.

  The sealed member 600 includes a base 601 and an engagement portion 602 that is bent at a substantially right angle from the base end of the base 601.

Fixed. The screw insertion hole 603 is a hole through which a screw 300 for screwing the circuit board 70 to the back side of the frame body 4 is inserted.

  The engagement portion 602 is a flat plate in which a strip-like (vertically long) engagement hole 604 with which the binding band 500 is engaged is formed. The height of the engaging portion 602 is set so that the upper region of the engaging hole 604 is exposed from the cover body 50 when the circuit board 70 is sealed. On the other hand, a fitting hole 55 for the engaging portion 602 is formed on the cover body 50 side. In particular, a counterbore 56 is machined on the inlet side of the fitting hole 55.

  Next, a procedure for sealing the circuit board 70 according to the second embodiment will be described.

  First, when the indicators 14 to 16 and the connector 60 are mounted on the circuit patterns on both surfaces of the circuit board 70, the sealed member 600 is also placed on the surface opposite to the surface facing the frame body 4 of the circuit board 70.

  Next, the screw 300 is inserted through the screw insertion hole 603 of the base portion 601 of the sealed member 600 and the screw insertion hole 72 of the circuit board 70 in this order, and is screwed into the screw hole 45 of the frame body 4. 4 is fixed. The sealed member 600 on the circuit board 70 tries to rotate together with the screw 300 due to the torque generated when the screw 300 is screwed, but the base 601 is brought into surface contact with the circuit board 70 and fixed by soldering. The sealing member 600 does not rotate with the screw 300, and the solder fillet F formed around the base portion 601 is not broken. Therefore, the circuit board 70 can be sealed without reducing the effective area of the circuit board 70 as much as possible.

  Then, the cover body 50 is attached so as to seal the circuit board 70 against the back side of the frame body 4. Specifically, as in the first embodiment, the screw 200 is inserted through the screw insertion hole 51 of the cover body 50 and the screw insertion hole 71 of the circuit board 70 in this order and screwed into the screw hole 44 of the frame body 4. The cover body 50 is fixed to the back side of the frame body 4. At this time, the engaging portion 602 of the sealed member 600 is fitted into the fitting hole 55 formed in the cover body 50, and the upper portion of the engaging hole 604 of the engaging portion 602 passes through the fitting hole 55. It is exposed from the cover body 50. Thereby, the alignment operation | work of the cover body 50 and the engaging part 602 of the to-be-sealed member 600 becomes easy.

  Finally, the circuit board 70 is sealed in a state where it is sandwiched between the frame body 4 and the cover body 50 by engaging the binding band 500 with the engaging portion 602 of the sealed member 600. Specifically, the band body 501 of the binding band 500 is bent, and the distal end portion thereof is inserted into the insertion portion 502 through the engagement hole 604 of the engagement portion 602. Then, a loop is formed by the band body 501, and the engaging claw of the insertion portion 502 is locked to the engaging claw group of the band body 501 in the pulling direction. The band body 501 cannot be pulled out from the insertion portion 502 due to the connecting action of the locking claw group of the band body 501 and the locking claw of the insertion portion 502. As a result, both the cover body 50 and the circuit board 70 are tightened. Thus, when the binding band 500 is engaged with the sealed member 600, the fitting hole 55 of the cover body 50 and the engaging portion 602 of the sealed member 600 are fitted and engaged as described above. The engagement portion 602 of the sealed member 600 is already positioned with respect to the cover body 50 so that the engagement hole 604 of the cover 602 is exposed, and a counterbore 56 is formed on the entrance side of the fitting hole 55 of the cover body 50. Therefore, the engagement work of both the binding band 500 and the sealed member 600 can be easily performed.

Thus, in the second embodiment, as the sealing structure of the circuit board 70, a sandwich structure in which the circuit boards 70 on which the indicators 14 to 16 and the connector 60 are mounted is sandwiched between both the frame body 4 and the cover body 50 is used. Further, the binding band 500 as a sealing member is engaged with the engaging portion 602 of the sealing member 600 soldered to the circuit board 70, thereby making it impossible to separate both the circuit board 70 and the cover body 50. Therefore, the same operations and effects as in (1) of the first embodiment are achieved.
Further, since the screw insertion hole 603 is formed in the base portion 601 of the sealed member 600 and the frame body 4 and the circuit board 70 are screwed together by the screw 300 inserted into the screw insertion hole 603, the above embodiment is described. The same operation and effect as 1 (2) are produced.

On the other hand, a pair of left and right screw insertion holes 75 through which the screws 500 are inserted are formed on the circuit board 70 side so as to communicate with the screw insertion holes 611H. A pair of left and right screw holes 48 into which the screws 500 are screwed are formed so as to communicate with the screw insertion holes 75 on the substrate 70 side.

  The engaging portion 612 protrudes forward from both left and right end portions of the housing main body 611 on the pin accommodating portion side so as to sandwich the contact pin 62, and a lock pin insertion through which the lock pin 100 is inserted is provided on the top plate. A hole 612H is formed. The engaging portion 612 is open forward and downward, and its cross-sectional shape is substantially U-shaped as shown in FIG. On the other hand, a lock pin insertion hole 58 through which the lock pin 100 is inserted is formed on the cover body 50 side, and a fitting recess 59 into which the upper portion of the engagement portion 612 is fitted is formed on the back side of the cover body 50. Has been. A lock pin insertion hole 58 is communicated with the fitting recess 59. The hole diameter of the lock pin insertion hole 612H is set slightly smaller than the hole diameter of the lock pin insertion hole 58.

  The contact pin 62 is fitted into a pin hole formed in the circuit board 70, and the tip thereof is soldered onto the circuit pattern on the surface of the circuit board 70 facing the frame body 4.

  Next, the screw 500 is inserted through the screw insertion hole 611H of the connector 60 and the screw insertion hole 611H of the circuit board 70 in this order, and is screwed into the screw hole 48 of the frame body 4, thereby fixing the circuit board 70 and the frame body 4. . At this time, a rotational moment is applied to the connector 60 on the circuit board 70 due to the torque generated when the screw 500 is screwed. The connector 60 has a large number of contact pins 62 fixed to the circuit board 70 by soldering. It will not be affected.

  Then, the cover body 50 is attached so as to seal the circuit board 70 against the back side of the frame body 4. Specifically, as in the first embodiment, the screw 200 is inserted through the screw insertion hole 51 of the cover body 50 and the screw insertion hole 71 of the circuit board 70 in this order and screwed into the screw hole 44 of the frame body 4.
