Abstract

The utility model relates to a password circuit switch, which comprises a casing, a digital rotating disk assembly and a digital display window. The utility model makes up the disadvantages of a plurality of prior circuit switches of being unsuitable for the electrical apparatus with a normally open circuit such as an alarm and other electric appliances and disables the tripping off the circuit without the correct input of the password, thus ensuring the normal use of the electric appliances. The utility model also has the advantages of low manufacturing cost, stable performance, long service life and low failure rate.

Description

Password circuit breaker

The utility model relates to a kind of password circuit breaker.

We generally adopt the contactor (as automobile, motorcycle etc.) of locking-type, but there am following technological deficiency in this prior art at present for for the purpose of making the contactor security personnel: the one, and it in use must the outfit key, and is cumbersome; The 2nd, its security personnel's poor-performing.Though the safety digital circuit switch that I have declared has overcome above technological deficiency, but it can only be suitable for the electrical equipment, the equipment that generally are under the normally closed situation of circuit and (that is to say that these electrical equipment, equipment are when inactive, circuit is to be in off-state, its selected digital position is to connect circuit), otherwise the more like electric equipment (as alarm etc.) that circuit is in often open just can not be suitable for.

The utility model just can remedy above prior art defective, provide a kind of needs normal open circuit, and its selected password position is the password circuit breaker of open circuit.

The utility model comprises: the profile housing with install within it digital rotating disk assembly and device at the digital display window (main distinction of the safety digital circuit switch that the utility model and I have declared is that the insulated part of former digital rotating disk assembly is changed into electric conductor, and conductiving point becomes insulating point: an electrode is divided into several and the corresponding conductive contact of the rotation number of turns) on its surface.

Owing to adopted above technical solution, the utility model just can remedy existing various contactor and safety digital circuit switch can not be applicable to the technological deficiency that some need the electric equipment of normal open circuit, to guarantee that this electric appliances equipment can be in the state that circuit is often opened in use, be unlikely to make other people open circuit easily of not knowing password, and make it lose due function.

Now further illustrate principle of the present utility model and feature again in conjunction with Figure of description.

Accompanying drawing 1: circuit interruption state diagram

Accompanying drawing 2: circuit on-state figure

Shown in the accompanying drawing 1: the utility model comprises external form housing (1), (digital figure place and turning collar number are corresponding for digital rotating disk assembly (2) (comprising turning collar and central shaft that several inside and outside discs amplexiform mutually) and digital display window (3), high more its privacy degrees of figure place is good more, here being example with three figure places) all to set an insulating point (being the password setting position) on each turning collar be the insulating point except that these three points (or several), the remainder of turning collar is all electric conductor (comprising axis), one electrode inserts axis, and another electrode is divided into three (or several) conductive contacts, and each contacts with three (or several) turning collars.When all numbers are turn-taked when all forwarding the password position that sets to, because of three of an electrode (or several) contacts all are on the insulating point that three (or several) turn-take, like this, circuit just has been interrupted.

As shown in Figure 2: as long as turn-take when not being in the password position that sets more than one, circuit is all connected when all three (or several).

Claims (1)

1, a kind of password circuit breaker comprises: profile housing (1) and the digital rotating disk assembly (2) (comprising several turning collars and central shaft) and digital display window (3) installed within it;

It is characterized in that an electrode is divided into several and the conductive contact of respectively turn-taking and touching mutually, another electrode inserts central shaft, the inside and outside disc of all turning collars all phase mutual connection pastes, a certain desired location at all turning collars all is provided with an insulating point, and the insulating point position of all turning collars all has password separately to show.
