A mounting piece (159) is provided. On the left and right ends of the mounting piece (159), there are provided bent pieces (159a) that are bent upward and engageable with the lower front portion of the second case body (13).

  The fixed portion (152) includes a front plate portion (153) that forms a front surface, upper and lower surfaces, and left and right side surfaces, and a rear plate portion (154) that forms a rear surface. The front plate portion (153) has a front surface corresponding to each of the third sealing portions (134), and the first elastic claws (163) of the sealing pins (16) can enter while being elastically deformed 4 A single locking hole (156) is formed.

  The substrate case (14) is slid to the right in a state where it is placed on the mounting piece (159) of the base bracket (15), so that each third sealing portion (134) is fixed to the fixed portion (152). It is set at a position where it overlaps with each locking hole (156).

  With the substrate case (14) set in the above-described position, each sealing pin (16) is temporarily fixed to each sealing portion (133) (134) as shown in FIG. When it is pushed deeper from the position, it is stopped as shown in FIG.

  As shown in FIG. 8, when the sealing pin (16) is in the temporarily fixed position, the front surface of the flange portion (161) of the sealing pin (16) is the second sealing portion (133) (and third). It penetrates into the second sealing portion (133) (and the third sealing portion (134)) to the extent that it does not protrude from the front edge of the sealing portion (134). The first elastic claw (163) elastically deforms the reduced diameter hole (133c) of the second sealing portion (133) (and the reduced diameter hole (134c) of the third sealing portion (134)) inwardly. Pass through and engage with the rear side of the partition wall (133b) (and the partition wall (134b)). The second elastic claw (164) approaches or slightly enters the reduced diameter hole (133c) (and the reduced diameter hole (134c)). Further, the thin piece portion (165) comes close to or abuts on the front edge of the cutting portion (136) or in the vicinity thereof. Thereby, the sealing pin (16) is in a state where the partition wall (133b) (and the partition wall (134b)) is sandwiched between the first elastic claw (163) and the second elastic claw (164). There is no rattling and it is securely held temporarily in the second sealing portion (133) (third sealing portion (134)).

As shown in FIG. 9, if the sealing pin (16) is in the fully latched position, the first elastic claw of the sealing pin (16) (163), the condensation of the first sealing portion (124) diameter hole ( 124b) (and the locking hole (156) of the base bracket (15)) while being elastically deformed inwardly, and a retaining member on the rear side of the front wall (124a) (and the front plate (153)) Match. The second elastic claw (164) elastically deforms the reduced diameter hole (133c) of the second sealing portion (133) (and the reduced diameter hole (134c) of the third sealing portion (134)) inwardly. Pass through and engage with the rear side of the partition wall (133b) (and the partition wall (134b)). Further, the thin piece portion (165) is pushed between the upper and lower cut portions (136) and (136) to be plastically deformed or broken.

  The first elastic claw (163) of the sealing pin (16) engaged with the fixed portion (152) of the base bracket (15) is engaged with the front plate portion (153) and the rear plate portion (154). ). Thereby, the first elastic claw (163) is illegally deformed inward by using a fraudulent tool, and illegal acts such as removing the sealing pin (16) from the fixed part (152) can be reliably prevented. it can.

  Furthermore, even when the rear plate portion (154) of the fixed portion (152) is illegally processed, it is possible to prevent the substrate case (14) from being illegally opened. That is, even if the first elastic claw (163) of the sealing pin (16) can be illegally deformed so as to come out of the locking hole (156) of the fixed portion (152), the second elastic claw ( 164) is engaged with the third sealing portion (134) so that the sealing pin (16) cannot be removed from the third sealing portion (134). The shaft portion (162) including the first elastic claw (163) cannot be removed from the fixed portion (152). As a result, as long as the shaft portion (162) is inserted into the locking hole (156), the board case (14) cannot be displaced from the mounting position, and the second case body (13) cannot be opened. .

  Next, the assembly procedure and operation of the control board unit (100) will be described. First, the main control board (8) is accommodated between the first case body (12) and the second case body (13), and the engagement claw (122) is engaged with the engagement hole (132) to form the board. Close the case (14).

  Next, the connecting plate (18) to which each sealing pin (16) is connected is fitted in the fitting groove (13a) provided in the second case body (13), and the sealing pin (16) As shown in FIG. 8, the shaft portion (162) is shallowly inserted into the second sealing portion (133) (and the third sealing portion (134)) and temporarily fixed. When the sealing pin (16) is in the temporary fixing position, as described above, the first elastic claw (163) has the reduced diameter hole (133c) (and the third seal) of the second sealing portion (133). Passing through the diameter-reduced hole (134c) of the stopper (134) while being elastically deformed, the partition wall (133b) (and partition wall (134b)) in the tube hole (133a) (and tube hole (134a)) Is engaged with the back side of the plate. At almost the same time, the second elastic claw (164) approaches or slightly enters the reduced diameter hole (133c) (and the reduced diameter hole (134c)), and the thin piece (165) is cut vertically. It approaches or abuts the front edge of the part (136). Therefore, if the sealing pin (16) is inserted deeper than the temporary fixing position, the force for deforming the thin piece portion (165) and the first elastic claw (163) are reduced to the reduced diameter hole (133c) (and the reduced diameter hole). (134c)) Since the force to enter is a resistance force, the sealing pin (16) can be reliably stopped at the temporary stop position, and the situation where it is accidentally pushed to the final stop position is prevented. Can do. Further, in the temporarily fixed state, the partition wall (133b) (and the second sealing portion (133)) between the first elastic claw (163) and the second elastic claw (164) of the sealing pin (16). Since the partition wall (134b) of the third sealing portion (134) is sandwiched, the sealing pin (16) is placed in the second sealing portion (133) (and the third sealing portion (134)). It is securely held temporarily without rattling and will not fall off. The sealing pin (16) may be temporarily fixed to the second and third sealing portions (133) and (134) in advance before setting the substrate case (14) to the base bracket (15). .

  FIG. 9 shows only the sealing pin (16) temporarily held by the second sealing portion (133) corresponding to the symbol (137) “A” after the sealing pin (16) is temporarily fixed. As shown in the figure, push it deeper into the full stop position. As a result, the flange portion (161) of the sealing pin (16) contacts the front surface of the partition wall (133b) of the second sealing portion (133), and the first elastic claw (163) moves to the first sealing portion. It passes through the diameter-reduced hole (124c) of the stopper (124) while being elastically deformed, and is engaged with the rear surface side of the front wall (124a) to prevent it from being removed, and the second elastic claw (164) is second sealed. It passes through the diameter-reduced hole (133c) of the portion (133) while being elastically deformed, and engages with the back side of the partition wall (133b). As a result, the second sealing portion (133) corresponding to the symbol (137) “A” is fixed to the first sealing portion (124), and the substrate case (14) is sealed. Further, the thin piece portion (165) corresponding to the symbol (137) “A” is pushed into the upper and lower cut portions (136) to be plastically deformed or broken.

  In order to attach the substrate case (14) sealed with the sealing pin (16) to the housing (2), first, a mounting piece of the base bracket (15) fixed in advance in the housing (2). In (159), with the lower part of the substrate case (14) placed, slide it to the right and set it to the mounting position. In the mounting position, the protrusion (125) of the first case body (12) is the blocking portion (157) of the base bracket (15), and the protrusion (138) of the second case body (13) is the base bracket. Engage with the notch (158) of (15). In this state, the board case (14) is fixed to the front surface of the base bracket (15) by tightening the screw (19) that engages with the notch (126) of the first case body (12).

  Next, only the sealing pin (16) temporarily fixed to the third sealing portion (134) corresponding to the symbol (137) “B” is brought into contact with the front surface of the partition wall (134b). Push deeply until touching. As a result, the first elastic claw (163) of the sealing pin (16) passes through the locking hole (156) of the base bracket (15) corresponding to the symbol (137) “B” while being elastically deformed inward. The fixed portion (152) enters the space portion (155) and engages with the back side of the front surface portion (153) of the fixed portion (152), and the second elastic claw (164) It passes through the diameter-reduced hole (134c) of the third sealing portion (134) while being elastically deformed inward, and engages with the back side of the partition wall (134b). As a result, the third sealing portion (134) corresponding to the symbol (137) “B” is fixed to the fixed portion (152) of the base bracket (15), and the substrate case (14) is sealed. Further, the thin piece portion (165) corresponding to the symbol (137) “B” is pushed into the upper and lower cut portions (136) to be plastically deformed or broken.

  In a state where the third sealing portion (134) is fixed to the fixed portion (152) of the base bracket (15), the first elastic claw (163) of the sealing pin (16) is connected to the front surface portion (153). And the rear surface portion (154). As a result, the sealing pin (16) can be pulled out by deforming the first elastic claw (163) engaged with the space portion (155) of the fixed portion (152) with the unauthorized tool inward. Can not.

  Further, even if an attempt is made to forcibly remove the sealing pin (16) from the third sealing portion (134), the two locations of the first elastic claw (163) and the second elastic claw (164) are the respective parts. Therefore, it cannot be easily removed. Even if some measure is taken and the first elastic claw (163) engaged with the fixed portion (152) is prevented from coming out of the locking hole (156), the second elasticity Since the claw (164) is engaged with the third sealing portion (134) in a retaining manner, the second case body (13) cannot be opened by removing the sealing pin (16). Furthermore, since the blocking portion (158) and the bent piece (159a) of the base bracket (15) are engaged so as to block the opening of the first case body (12), the board case (14) Even if it tries to open forcibly, the second case body (13) cannot be opened.

  When the electronic component (81) of the main control board (8) is to be inspected after the board case (14) is fixed to the base bracket (15), the first corresponding to the symbol (137) "B" The third sealing portion (134) is formed by cutting each of the cutting portion (136) of the three sealing portion (134) and the cutting portion (18a) connected to the sealing pin (16) with a tool such as a nipper. Are separately separated from the second case body (13) and the sealing pin (16) from the connecting plate (18). Thereafter, the screw (19) is loosened and the substrate case (14) is moved to the left to be removed from the base bracket (15).

  After the substrate case (14) is removed from the base bracket (15), the cutting part (136) of the second sealing part (133) and the sealing pin (16) corresponding to the symbol (137) “A” are cut. Each part (18a) is cut. As a result, the second sealing portion (133) and the sealing pin (16) corresponding to the symbol (137) “A” are separated from the first case body (12), so that the substrate case (14) is opened. The main control board (8) can be taken out and inspected.

  When the main control board (8) is inspected by an external inspection organization, the second sealing part (133) corresponding to the symbol (137) “F” is sealed by the sealing pin (16). The pin 16 is transported to an external inspection organization while being fixed to the first sealing portion 124. As a result, the substrate case (14) is not tampered with during the transfer of the substrate case (14).

  After the inspection, the substrate case (14) is discarded. Then, an unused board case (14) is prepared, the main control board (8) is accommodated in the board case (14), and the second sealing portion (133) corresponding to the symbol (137) “A” is provided. Then, it is sent back in a state of being fixed to the first sealing portion (124) by a separately prepared unused sealing pin (16).
