Wherein, the upside of the 1st printed circuit board (PCB) (54) and the 2nd printed circuit board (PCB) (56) is respectively arranged with various electric-controlled parts (70), and electric-controlled parts (70) includes chip (70a), radiator (70b), electric capacity (CONDENSER) (70c) and resistance (70d) etc.Mainly be provided with on the 1st printed circuit board (PCB) to exchange and use electric-controlled parts; In addition, mainly be provided with the direct current electric-controlled parts on the 2nd printed circuit board (PCB).
On the one hand, be formed with hole, angle (57) respectively on the 1st printed circuit board (PCB) (54) and the 2nd printed circuit board (PCB) (56), the effect of hole, angle (57) is the insulation distance that shortens between the electric-controlled parts (70), improves the integrated level of circuit.
In addition, compressor relay (58) is formed on the inside upper part of Box Cover (60); Power supply terminal (58a) exposes the upside in compressor relay (58), and power supply terminal (58a) is used to link the end of power line (62), and electric current is flowed.
In addition, signal transfer line (64) links with each electric-controlled parts (70) or links to the outside, and signal transfer line (64) is connected with power line and electric-controlled parts (70), transmits the various signals that are used for the outer machine spare of control cabinl pulpit.Portion of terminal (68,76) be formed on the following side of control cabinet (90) and lateral surface one side of Box Cover (60), portion of terminal (68,76) constitute by a plurality of signal terminals (76a), a plurality of signal terminals (76a) are connected with power line (62) and the signal transfer line (64) of supply power supply, to as the device work of electric-controlled parts (70) etc. supply power supply or transmission signal.
On the one hand, the medial surface edge of Box Cover (60) is formed with and inserts line (60a), the insertion line (60a) that can be inserted in casing (52) inboard, front after casing (52) is gone up, can interdict Box Cover (60) secure bond air and flow in the casing (52) as seal.
In addition, when compressor relay (58) was gone up generation flame, on other inflammability parts of preventing something from spreading, Box Cover (60) was formed by flame resistant material.
Below, the assembling process of the control cabinet of off-premises station of the present invention with structure is carried out simple declaration.
At first, electric-controlled parts (70) is separately positioned on the upside of printed circuit board (PCB) (54,56); Partition wall (52a) with casing (52) is a benchmark, and printed circuit board (PCB) (54,56) is separately positioned on the upper and lower.
In addition, the power line (62) that will run through the inboard power supply wire harness (66) of casing (52) inserts and is attached on the power supply terminal (58a) of compressor relay (58), and compressor relay (58) is arranged on the inboard of Box Cover (60).
Wherein, when power line (62) being inserted on the power supply terminal of compressor relay (58), need apply certain strength, but because compressor relay (58) and Box Cover (60) firmly formation integratedly, so can prevent the breakage of compressor relay (58) and other circumferential component.
On the one hand, for the various devices to compressor relay (58) and off-premises station transmit signal, signal transfer line (64) is attached on the electric-controlled parts (70).
When finishing printed circuit board (PCB) (54, after the binding of setting 56) and power line (62) and signal transfer line (64), the insertion line (60a) that then will be formed on Box Cover (60) inside edge, front is inserted into the medial surface of casing (52), secure bond Box Cover (60).
After finishing the secure bond of Box Cover (60), interdicted to the air that with partition wall (52a) is casing (52) top of benchmark and flowed into, when high pressure causes compressor relay (58) to produce flame, owing to limited the amount of oxygen in the casing (52), so can prevent that propagation of flame is to other inflammability parts of periphery.
The control cabinet of air conditioner outdoor unit provided by the invention can bring following effect.
In the control cabinet of air conditioner outdoor unit of the present invention, compressor relay is arranged on the Box Cover, Power line firmly is attached on the power supply terminal of compressor relay, prevents from linking at power line Cause the parts breakage owing to apply strength in the process on the power supply terminal of compressor relay. Because will Compressor relay is not arranged on the printed circuit board (PCB), not only can easily guarantee establishing of printed circuit board (PCB) Put the space, and can make printed circuit board (PCB) with small size, dwindled the whole size of control cabinet.
In addition and since can with Box Cover and casing closely secure bond be in the same place, when the compressor relay When producing flame on the device, the damage that can prevent from being arranged on the inflammability electric-controlled parts on the printed circuit board (PCB) with And breaking out of fire.
