Description

Control panel for air compressor easy to installation and wiring of eiectronic parts

The present invention, as well as the electronic switchgear, overload switch, pressure switch, power switch, driving light, etc. used for the control of the air compressor, assembling and installing a large number of electrical appliances, such as the outer panel to the control panel, as well as wiring work without further interference. The present invention relates to a technique for simplifying the overall structure of the control panel while being conveniently implemented.

A general piston type air compressor for producing compressed air is a type of assembly in which a compression pump and a motor for driving the compression pump are assembled on a horizontally arranged receiver tank and a control panel for controlling the air compressor is mounted. It consists of.

The control panel for the air compressor is the electronic switchgear, overload switch, automatic pressure switch, power lamp, driving lights, etc., and concentrated in one place electronic components, the most common control panel for air compressors are currently 8 and. Likewise, the front panel of the housing 2 made of steel or synthetic resin is fixed to the control panel mount 1b attached to the receiver tank 1a of the air compressor 1, and fixedly installed. The front cover 2b is installed on the front surface of the hinge shaft 2a so as to be opened and closed.

In addition, electrical appliances such as an electronic switch 3, a connection terminal 4, and a transformer are installed on the rear surface of the housing 2, and the selector switch 5 penetrates inside and outside of the front cover 2b. Attached electronic devices providing additional functions such as various lamps 6 and outer meters are installed, and the pressure switch installed on the receiver tank 1a operates to stop the power first by pressure. 5) and the selector switch 5 is connected to the intermittent field coil of the electromagnetic switch 3 via the connection terminal board 4.

However, even if the control panel opens the front cover 2b as shown in FIG. 8, the housing 2 is only open at the front, and thus the space is clogged so that the space required for the wiring work is very narrow and narrow. It was a lot of power and difficulty to do the complicated wiring work to connect and finish the wiring necessary for the electronic switch.

In addition, the front cover (2b) is necessary for the purpose of sealing the enclosure (2) even if the attached electronics (optional functions such as selector switch, lamp, etc.) providing additional functions to the front cover is not required, Since the separate control panel mount 1b for fixing (2) must be installed in the receiver tank 1a, a lot of unnecessary parts are required, resulting in a high cost of manufacturing.

In addition, the various types of accessory electrical appliances (selector switch, lamp, etc.) attached to the front cover and the connection terminal board 4 installed on the enclosure 2 are connected by several strands of control lines 7 so that the front surface can be inspected for internal inspection. Even if the cover is opened, the front cover 2b does not open completely due to the heavy weight of the control line 7 and the short length, and the front cover is automatically closed as the control line 7 is pulled out. The maintenance work is difficult and inconvenient.

In view of such a reality, a method of installing the electronic switch in the housing 2 after completing the wiring work for previously connecting the wires necessary for the electronic switch in advance has been proposed, but this has been extremely limited.

That is, the motor connection line and the power supply line (220V ~ 380V) must pass through the inside and outside of the enclosure (2), the cord formed at the end of the motor connection line or the end of the power supply line passes through the wire through hole formed in the bottom of the enclosure After entering inside, it was difficult to connect each wire connector by bending it more than 90 degrees at 90 ° while passing through a narrow place.

Therefore, it is easy to assemble and install electric appliances such as electronic switchgear, overload switch, pressure auto switch, selector switch, power lamp, driving lamp used for controlling air compressor, and control panel that can make wiring work conveniently without any interference. This situation is urgently required in the industry.

The present invention is to actively solve the problems that the control panel for the air compressor according to the prior art is contained, the installation and wiring work of the electrical equipment such as electronic switchgear on the top of the multi-base open all the way to the receiver tank and The control panel for the air compressor can be implemented by a simple method of convenient installation without interference in a separate work place and assembling and installing the multi-base where the assembly, installation, and wiring of the electric equipment are completed in a seated state on the electric base attached to the receiver tank. It is to be an object of the invention.

In addition, the present invention is a simple way to install a selector switch, a lamp (power indicator, operation indicator) in a complex manner on the front panel of the multi-base, while conveniently installing a high-quality control panel that meets the functions and economic needs, compact overall It is an object of the invention to achieve a structured.

In addition, the present invention is to solve the problem that the electronic switchgear can be safely protected by a method of closing the control panel cover on the upper portion of the electric base.

The present invention is a multi-installed integrally attached to the receiver tank, the electric base is formed in the receiver tank, the electric wire passage formed in the top plate and the front and rear plates in a continuous manner as a means for solving the above problems. The base is manufactured as a separate unit separated from the receiver tank, but a plurality of wiring holes penetrate up and down in the upper plate of the melty base, and a technique for assembling and installing an electronic switch on the upper part of the multi-base is devised.

In addition, the present invention provides a technique for installing a variety of accessories in the front plate of the multi-base, and freely connecting the control wire connected to the contact of the electronic switchgear through the wiring through the multi-base and the accessory.

In addition, the present invention devises a technique for seating and installing a control panel cover on the top of the multi-base to protect the electronic switch so as not to be exposed to the outside.

According to the present invention, the multi-base is open in all directions is manufactured in a separate unit separate from the receiver tank, the interference in the state in which the various electrical appliances, such as electronic switchgear to the multi-base in the dedicated work environment excellent in the work environment is open It provides the effect that can be easily assembled and installed without wires, and in particular, the assembly and installation and wiring of such electrical equipment to multi-base, mass production, speed up, while improving productivity while dramatically reducing labor and time Provide effect.

In addition, the multi-base assembly of the electrical installation and wiring is completed by assembling and installing in a seated state on the electric base attached to the receiver tank provides an effect that can implement a final control panel for the air compressor very quickly and conveniently.

In addition, the control panel by accommodating the electronic switchgear and the various accessories in the multi-base at the same time, while more easily connecting the control wires connected to the contacts of the electronic switch and the various electrical equipment (switch, lamp, etc.) installed on the front panel of the multi-base The overall structure of this provides a very simple effect.

In addition, by closing the control panel cover on the upper end of the multi-base so as to surround the outside of the electronic switch can provide an effect of protecting the electronic switch safe from external forces.
