Description

Terminal for electric dust collector {TERMINAL FOR ELECTRIC DUST PRECIPITATOR}

The present invention relates to a terminal for an electric dust collector, and more particularly, for an electric dust collector used to supply operating power to the positive and negative plates of an electric dust collector mounted on an air conditioner, an air cleaner, and the like to collect dust and pollutants to clean air. It's about the terminal.

In general, an electric dust collector is a device that generates electricity by applying an electric field to a gas, especially dust suspended in air, and collects particles with electrostatic force to clean the gas, from plant equipment such as a power plant to air conditioners, air cleaners, etc. It is widely used for electronic products.

That is, the electrostatic precipitator used in electronic products such as an air cleaner utilizes an operating principle of imparting polarity to the dust in a neutral state.

To this end, a corona discharge is generated by applying a high voltage in the air by using a wire or the like, and by the ions generated thereby, dust particles are charged to become charged particles, and then a lower anode plate to which an electric field is applied, The charged particles are attached to the surface of the negative electrode plate and removed by Coulomb force.

This electrostatic precipitating technique has the advantage of low pressure loss of flowing air, but should be configured to supply stable operating power to the positive and negative plates.

The connecting structure of the electrostatic precipitator according to the prior art may be provided in the electrostatic precipitator, as shown in FIG. 1 as Korean Patent Application No. 10-1997-020080.

The prior art electrostatic precipitator includes a front panel (not shown) in which a suction hole is formed and a plurality of wires are installed across the suction hole and provided with a + current; A lattice type positive electrode plate (1) and negative electrode plate (2), which are in close contact with the inside of the front panel and are spaced apart from each other by a predetermined interval and are respectively applied with + and − currents; It is coupled to the front panel and the screw, etc., and also comprises a back plate (not shown) which supports the positive electrode plate 1 and the negative electrode plate 2 and has a ventilation hole formed therein.

Prior to the prior art, in order to apply an electric current to the positive electrode plate 1 and the negative electrode plate 2, the fixing hole of the positive electrode plate 1, the fixing hole on one side of the negative electrode plate 2, and the annular terminal terminal formed at the ends of the + and-wires (Not shown).

On the contrary, in the related art, fitting portions 3 and 4 formed on one side of each of the positive electrode plate 1 and the negative electrode plate 2; Fitting connectors 5 and 6 for fastening to the fitting portions 3 and 4 were provided to provide a firm coupling while simplifying the assembly work.

However, since the connecting structure of the electrostatic precipitator according to the prior art uses only one connecting position and a fitting connector, which are one connection position, for the application of current to the positive electrode plate or the negative electrode plate, the plurality of positive electrode plates and the negative electrode plates are individually provided. There is a disadvantage that the current can not be supplied, the operating efficiency may be reduced.

For example, the plurality of the positive electrode plates and the negative electrode plates of the prior art are combined in a lattice shape to be physically or electrically simply contacted, but a region of local contact, non-contact, etc. may occur during the product assembly step according to a simple contact state, so that the positive electrode plate And the negative plate have the disadvantage that the unstable current supply can be made.

Since the connecting structure of the prior art electrostatic precipitator is arranged in tens to hundreds of positive and negative plates in the electrostatic precipitator, it is very difficult to separately provide current supply to each of these positive or negative plates.

For this reason, the connecting structure of the prior art electrostatic precipitator has a process of assembling the positive electrode plate and the negative electrode plate in a lattice form, and the electrical connection that connects the fitting connector of the current supply wire to the fitting portion of any one of the assembled positive or negative plates. There is still a disadvantage in that the efficiency of the work is still reduced since the connecting process and the assembly work for joining the front panel and the back plate must be performed.

In addition, the prior art electrostatic precipitator is very difficult to expect innovative working efficiency because the combination of the front panel and the back plate does not improve the lattice state of the positive and negative plates, or the electrical connection state does not affect well. There is this.

As such, the prior art electrostatic precipitator does not include any technical configuration that can provide stable contact performance while individually applying current to the positive electrode plate or the negative electrode plate, and can also stabilize the electrical contact state through assembly. There are disadvantages in that electrical connection state or current supply state is relatively unstable, high quality electric precipitator cannot be produced, and problems such as frequent AS service or replacement due to poor contact quality can be produced.

An object of the present invention was devised to solve the problems of the prior art as described above, by providing a terminal pressing portion of one case for the dust collector, a contact terminal of the case installation type, and a terminal support portion of the other case for the dust collector, By simply combining the dust collecting plate and the negative electrode collecting plate with the other case, the physical arrangement and the electrical contact of the collecting plates can be made separately at the same time, and then the electrical contact state can be maintained more firmly according to the combination of the case and the other case. We want to provide a terminal for an electrostatic precipitator that can provide work and excellent connection quality.

An object of the present invention as described above, in the terminal for the electric dust collector for supplying current to each of the plurality of positive electrode dust collector plate or the negative electrode dust collector plate arranged inside the separate case of the electric dust collector, it is installed in the case, the positive electrode dust collector plate or A contact terminal having a plurality of terminal contacts arranged at equal intervals corresponding to the negative electrode dust collecting plate, a terminal stand connected to the terminal contacts integrally with each other, and a terminal base at which the terminal stands are connected at equal intervals. Achieved by a terminal for an electrostatic precipitator.

In addition, according to the present invention, it is preferable that a plurality of terminal support portions respectively supporting the terminal contacts are formed on the other side of the case.

In addition, according to the present invention, it is preferable that a plurality of terminal pressurizing portions are formed at one side of the case to insert and engage in a space between the terminal support portions to press the positive electrode collecting plate or the negative electrode collecting plate toward the terminal contact.

Therefore, the terminal for electric dust collector according to the present invention is composed of a contact terminal, a terminal support part, and a terminal pressing part installed on the left and right sides of the inside of the other case for supplying current of the positive electrode and the negative electrode collector plates, corresponding to the number of dust collector plates. While maintaining a constant gap between the positive electrode collector plate and the negative electrode collector plate through a contact terminal having a terminal contact that can be contacted at equal intervals, there is an advantage that the current can be stably supplied to the positive electrode collector plate or the negative electrode collector plate.

In addition, the terminal for the electrostatic precipitator according to the present invention may be fitted to the corresponding second plate guide protrusion and the third plate guide protrusion arranged in the other case, and each positive electrode collector plate or the negative electrode collector plate may be energized to the contact terminal. In this case, the assembly process and the wiring process of the positive electrode collector plate or the negative electrode collector plate can be simultaneously performed, and thus, there is an advantage that the wires can be robust and stable while shortening the entire assembly process.

In addition, the terminal for the electrostatic precipitator of the present invention is inserted and engaged with the space between the terminal support portion of the other case when the one case and the other case is coupled, so that the positive electrode collector plate or the negative electrode collector plate is the contact terminal By being closer to the, it is possible to strengthen and maintain a more reliable contact state, to mass-produce a high-quality electric dust collector without error, there is an advantage that can solve the problem of poor contact quality.
