Casing 22 has the maintenance case 32 of holding circuit substrate 21 and the lid 33 that sealing keeps case 32.The front openings of casing 22, rear side is provided with and keeps case 32.Lid 33 covers the opening of front sides, and can install and remove and be installed on maintenance case 32.Circuit substrate 21 is installed along fore-and-aft direction.

As shown in Figure 8, on casing 22, be provided with a pair of maintaining part 40,41 for holding circuit substrate 21.One side's maintaining part 40 can move with respect to circuit substrate 21, and the opposing party's maintaining part 41 is held in circuit substrate 21 can move.Each maintaining part 40,41 is separately positioned on front side and the rear side that keeps case 32.Front side as the maintaining part 40 hook holding circuit substrates 21 of the front side of a side maintaining part.Described maintaining part 40 possesses the pawl 42 of flexible.Relative with the upper and lower a pair of pawl 42 being formed on casing 22, keeping being formed with respectively bearing 43 on case 32.By pressed the circuit substrate 21 with bearing 43 butts by pawl 42, come the front side of holding circuit substrate 21.Pawl 42, by elastic bearing, is bent upwards in front and back.That is, the maintaining part 40 of front side can move with respect to circuit substrate 21.By making pawl 42 lateral bend mobile forward, pawl 42 leaves circuit substrate 21, thereby has removed the maintenance of 40 pairs of circuit substrates 21 of maintaining part of front side.

As the maintaining part 41 of the rear side of the opposing party's maintaining part, clamp the rear side of holding circuit substrate 21.Described maintaining part 41 has the gap 45 that the rear side of the circuit substrate of insertion 21 is clamped.Rib 46 and pedestal 47 that gap 45 is oppositely arranged by left and right directions form.Rib 46 relies on outside than pedestal 47.Opposed faces rib 46 and pedestal 47 tilts, and gap 45 becomes taper.As shown in Figure 9, when the rear side of circuit substrate 21 embeds in gap 45, if remove the maintenance to the front side of circuit substrate 21, circuit substrate 21 can move to the state of inclination laterally.When circuit substrate 21 tilts, terminal base 24 is left in the front side of circuit substrate 21.That is, the maintaining part 41 of rear side allows that the inclination of circuit substrate 21 moves.

By the upside and the downside that are arranged at the upper and lower guide wall 48 holding circuit substrates 21 that keep case 32.In casing 22, circuit substrate 21 is fixed on assigned position by the maintaining part 40,41 of front and back and upper and lower guide wall 48.

The lid 33 of casing 22 covers upper surface, lower surface, front surface and the right flank of the opening of casing 22.Outer wall 50 and the relative formation of perforated wall 49 that keeps case 32 front sides, the rear side of lid 33 is by opening edge 49 and outer wall 50 clampings.The front side of lid 33 is by compressing tablet 51 clampings of pawl 42 and formation relative to pawl 42.By front side and the rear side of clamp cover 33, lid 33 is installed on and keeps case 32.

Lid 33 front side insert cover 33 and compressing tablet 51 between.Thus, pawl 42 is pressed towards circuit substrate 21.The movement of pawl 42 is restricted, and can from circuit substrate 21, throw off by anti-claw stop 42, thereby circuit substrate 21 can not rocked.

On circuit substrate 21, be mounted with the electronic components such as connector.Connector is connected with from the wire of terminal base 24 with towards the wire of fan electromotor.Wire, from the outside wraparound of casing 22, is connected with the connector in casing 22.On lid 33 front surface and lower surface, be formed with the pilot hole 52 for break-through wire.From the outstanding toward the outer side wire support 53 that is provided with of terminal base 24.From many wires of terminal base 24, by described support 53 boundlings, and insert in casings 22 from covering 33 pilot hole 52.

In addition, a part for terminal base 24 is positioned at the place ahead of casing 22.By terminal base 24 being relied on to outside configuration, the width of the left and right directions of electrical box 20 diminishes, and can reduce receiving space.And the position corresponding to casing 22 forms insertion passage 29, to determine the position of insert port 30.Owing to can making terminal base 24 reach the place ahead of casing 22, so connector 31 can be relied on to outside configuration.Therefore, can make the connector 31 of terminal base 24 and insert port 30 be positioned on straight line.Electric wire 23 can be connected up as the crow flies, make the connection operation of electric wire 23 become easy.

Terminal base 24 reaches the place ahead of casing 22.While therefore, taking in, in the place ahead of circuit substrate 21, there is terminal base 24.In order to place under repair etc., from casing 22, take out circuit substrates 21 sometimes.At this, utilize the idle space of the front side of casing 22, make circuit substrate 21 can avoid terminal base 24 and pass in and out.

When taking off front panel 11 from cabinet 3, taking off while covering 33 from casing 22, idle space is opened to, upper side direction and lateral direction towards front side.Circuit substrate 21 depart from position while taking in and laterally direction move.Thus, when circuit substrate 21 turnover, terminal base 24 can not become obstacle.Circuit substrate 21 can pass in and out by any direction from the place ahead, top, below, lateral direction by idle space.During turnover, there is not in any direction barrier.There is not this barrier of wire support 53 in the top of casing 22 for example.Operator can, corresponding to operator position, make circuit substrate 21 with respect to the smooth and easy turnover of casing 22 from the direction of easy operation.

On circuit substrate 21, be mounted with highly different electronic components.There is idle space in the front side of casing 22.Therefore the electronic component arrangements that, transformer, capacitor, noise filter equal altitudes are high is in the front side of circuit substrate 21.Highly low electronic component is mainly configured in the rear side of circuit substrate 21.Owing to configuring large electronic component at idle space, so the heat producing from electronic component can not be accumulated and can dispel the heat.

When operator takes out circuit substrate 21, first take off front panel 11, and pull down and cover 33 from casing 22.As shown in Figure 5, circuit substrate 21 presents.When taking off while covering 33, removed the restriction to pawl 42.Operator makes pawl 42 forward during side shifting, and pawl 42 leaves circuit substrate 21.

As shown in Fig. 9,10, operator topples over circuit substrate 21 laterally.Rear side original state at circuit substrate 21 is embedded under the state in gap 45, and the front side of circuit substrate 21 tilts laterally.Circuit substrate 21 leaves upper and lower guide wall 48.Because highly high electronic component is loaded in the front side of circuit substrate 21, so even if circuit substrate 21 tilts, electronic component can not contact yet and keep case 32.Thus, circuit substrate 21 becomes the state that can take out from casing 22.

Operator shifts to outside by the front side of circuit substrate 21, and forwards takes out circuit substrate 21.From gap, 45 extract the rear side of circuit substrate 21, thereby take out circuit substrates 21 from maintenance case 32.Thus, utilize the movement of circuit substrate 21, can avoid being positioned at the terminal base 24 in the place ahead, make the turnover operation of circuit substrate 21 become easy.

When mounting circuit substrate 21, circuit substrate 21 is inserted from the place ahead of casing 22, and the rear side of circuit substrate 21 is inserted to gap 45.Circuit substrate 21 in heeling condition is laterally by when inner side is pressed into, and pawl 42 is bent by circuit substrate 21, and pawl 42 is crossed in the front side of circuit substrate 21, and is finally stuck on pawl 42.Lid 33 is installed to and keeps after case 32, and pawl 42 is pressed, and circuit substrate 21 is firmly fixed, thereby is accommodated in casing 22.

In addition, the invention is not restricted to above-mentioned embodiment, certainly can to above-mentioned embodiment, carry out various modifications and changes within the scope of the invention.The maintaining part that can be front side is held in the front side of circuit substrate can move, and the maintaining part of rear side can move.Now, keep case to be arranged on the front side of circuit substrate, lid is arranged on the rear side of circuit substrate.The maintaining part that can move in addition, also can adopt the pawl that can slide.By pawl being applied to active force by spring, pawl is moved to circuit substrate.

The turnover direction of circuit substrate can also be top, below and lateral direction except the place ahead.But, in the situation that the turnover direction of circuit substrate is lateral direction, keep case to become obstacle.At this, maintenance case is reduced and will cover increasing.Thus, can be by the circuit substrate smooth and easy taking-up of direction laterally.

Not only the maintaining part of front side can move, and can also make the maintaining part of rear side also can move.The rib that is formed with pyramidal space is for example displaceably set on maintenance case.Rib applies active force by spring and can move.When taking off while covering, removed the restriction to the maintaining part of front side, when the maintaining part of front side moves, the rib of the rear side of holding circuit substrate utilizes the active force of spring and moves.For example rib is mentioned, and direction moves or direction slip up and down to the left and right.Thus, by circuit substrate is moved up in the side different from fore-and-aft direction, circuit substrate becomes the state easily taking out from casing.

Maintaining part at least front and back is a pair of, but can be also more than three.And, front side or the rear side of at least one the maintaining part holding circuit substrate in a plurality of maintaining parts.The opposition side of fore-and-aft direction of other maintaining part holding circuit substrate, in the upside of the downside of circuit substrate, circuit substrate more than one.

In the above embodiments, electrical box is configured in the right side of cabinet, but also electrical box can be configured in to the left side of cabinet.Now, the structure of electrical box left and right is inverted.
