The present invention relates to an auxiliary contactor of an electronic switch or an auxiliary relay, and more particularly, to an auxiliary contactor which makes it easy to switch a contact for contact to an open b contact or vice versa.

In the battery control system, when an electric signal is used to control the operation of an electric appliance of the control system, an auxiliary contact or an auxiliary relay of an electronic switch is used to connect or open an electric signal applied to the electric appliance. In order to change the operation of the electrical equipment of the control system, it is possible to change the contact state of the electrical circuit to which the electrical equipment is connected. That is, when the relay is to be operated (suction) from the control system to which the circuit is connected, and when the auxiliary relay is to be operated (suction), the contact operation of the auxiliary relay is changed to the contact point (contact a). It is possible to change from open contact (b contact) to. In a common auxiliary relay, as shown in FIG. 3, the movable core 5 and the fixed core 6 are separated from each other by the spring 8 in normal time, but when the voltage is applied to the coil 7, the movable core ( 5) and the fixed core 6 is magnetized to generate attraction between each other, and as a result, the movable core 5 moves toward the fixed core 6. At this time, the movable contactor support 1 connected to the movable core 5 moves together, and the movable contactor 2 installed on the movable contactor support 1 moves together to come into contact with the fixed contactor 3 fixed to the outer case. Both ends of the contact ends 3 and 3 'are electrically connected.

In order to change the connection state of the electric fan of the control system with the auxiliary contact of the conventional switchgear or the contact relay, the fixed contactor 3 having the contact a contact as shown in FIGS. The fixed contactor 4 having an open b contact or a rotating contactor 3 as shown in Figs. 2A and 2B was possible by changing the assembly form.

That is, in the case of the conventional FIG. 1, in the case of changing from the contact a contact to the open b contact, the fixed contact 3 of the contact a contact is replaced with the fixed contact 4 of the open b contact, and the movable contactor is installed. The assembly position of (2) should be changed.

In the case of the conventional fixed contactor rotation method of FIG. 2, when the contact a contact is to be changed to the open b contact, the fixed contact 3 must be reversed and assembled, and the movable contact 2 is also assembled. Should be changed to be on top.

However, when the contact structure of the conventional auxiliary relay has the structure shown in FIG. In the case of 2 degrees, the fixed contactor that is already installed can be used as it is, but since it must be assembled upside down after dismounting from the product, the shape of the fixed contactor may be deformed, especially when checking the contact state of the contact during use. It was difficult to check with the naked eye, and there was an uneconomical disadvantage in the processing of the fixed contact.

The present invention is to use a separate fixed contactor as a conventional problem described above, or to solve the deformation of the fixed contactor, increase the cost, the difficulty of contact inspection, etc., and will be described in detail with the accompanying drawings.

According to the present invention, the contacts 13A and 13B are attached to the upper and lower sides of the fixed contact 13 as shown in FIGS. 4 and 5 at the auxiliary contact of the electronic switch or the auxiliary calculator, and the movable contact 12 ) Is caught by an intermediate portion of the movable contactor support 11 so that the movable contactor support 11 operates as the contact a contact (FIG. 4A) or as the opening b contact (FIG. 4B) along the up and down moving state. When the fixed contact member 11A is attached and the movable contact 12 is switched from the contact a contact state as shown in FIG. 4A to the open b contact state as shown in FIG. 4B, only the installation position is changed.

Referring to the operation example of the present invention by the above configuration, Figure 4a shows a case of using as a contact for the contact, the movable contactor 11 is installed as the movable contactor (11) moves downwards ( 12) moves in the same manner so that the contact a closes to the contacts 13A and 13B of the fixed contacts 13 and 13 ', so that the fixed contacts 13 and 13' on the side are in an electrically energized state.

FIG. 4B shows that the movable contactor 11 moves downward by changing the installation position of the movable contactor 12 in the lower position of the fixed contactors 13 and 13 '. The contacts b of 12 and 12 'are closed by the contacts 13A and 13B of the fixed contacts 13 and 13' provided on both outer cases, so that the fixed contacts 13 and 13 'on the side are electrically energized. .

As described above, the present invention can facilitate the conversion of the contact a contact to the opening b contact or vice versa in the auxiliary contactor of the electronic switch or auxiliary relay, and additionally use or fix the fixed contact as in the prior art. There is an effect that can solve the inconvenience in the deformation of the contact.
