Description

[0001] The present invention relates to a cap for a slide switch having a trip coil unit,

The present invention relates to a slide switch cap provided in a leak current trip coil unit of an earth leakage breaker, more specifically, to a slide switch provided in a leakage current trip coil unit and coupled to the slide switch, And the switch interlocking member is configured so as to enclose the switch interlocking member so that soot and dust or the like due to a short-circuit or the like are prevented from flowing into the inside of the electric leakage trip coil unit.

Typically, an earth leakage breaker is one of the safeguards to shut off the circuit by hiding the occurrence of abnormal current such as leakage current, ground fault and human electric shock accident.

The operation of the earth leakage breaker as described above is as follows.

When an abnormal current such as a leakage current, a ground fault, and a human body is generated from the load side, the ZCT (Zero Current Transformer) stored in the circuit portion detects the abnormal current and transmits the sensed signal to the substrate. The IC judges whether the circuit is blocked or not.

1 is a perspective view of a general earth leakage breaker. 1, the earth leakage breaker includes a cover 1 and a case 2 forming an outer shape, a handle 3 provided on the upper surface of the cover 1 for opening and closing a circuit, A leakage current test button 5 for preliminary checking, and a leakage current trip coil unit for sensitivity and time setting are formed on one side of the earth leakage breaker.

Further, the electric trip trip coil unit is provided with a slide switch 6, and the switch cover 15 is coupled thereto while exposing the slide switch 6.

Fig. 2 is a sectional view II-II of Fig. 1. Fig. 2, a cover 1 and a case 2 of the earth leakage breaker are provided with an electrical leak detecting portion 7 for detecting a leakage current generated in a load, An overcurrent detecting unit 10 for detecting an overcurrent or a shortcircuit current in addition to a leakage current, and an overcurrent detecting unit 10 for detecting an overcurrent or a shortcircuit current, And a power source side terminal block 12, a load side terminal block 13, and the like.

Referring to FIG. 2, when an abnormal current such as a short circuit, a ground fault, and a human body is generated from the load side, the ZCT (Zero Current Transformer) . When it is determined to be a fault current, the signal is transmitted to the electronic device section 8. At this time, the electronic device section 8 quickly drives the switch device 9 to shut off the circuit.

However, in the case of the above-described earth leakage breaker, when a short-circuit accident occurs, the soot flows inward, and the contact between the elements and the substrates is not smooth due to the soot, There has been a problem that frequent accidents occur.

Also, even if there is no short-circuiting accident, dust and foreign matter enter into the clearance of the switch cover 15, so that the contact of the elements and the substrates is not smooth, and the circuit breaker is not operated.

In addition, when the switch cover 15 is opened, the cap 6 may be detached at the same time, which may cause the cap 6 to be lost.
