Abstract

The utility model relates to a mechanical timing combined switch which is formed by the combination of a mechanical timer with a main and an auxiliary double contacts and two power sockets, wherein, the mechanical timer with the main and the auxiliary double contacts is formed in the way that an existing movable cut type mechanical timer of a single contact is retrofitted into a conversion type mechanical timer of double contacts, which is firstly cut and then closed. The utility model has the advantages of low manufacture cost, simple use method, particular stable and reliable timing and the avoidance of the influence of power failure.

Description

Mechanical timing combined switch

The utility model relates to and has can the adjusting so that measure the device in the time interval that can set up of mechanical driving mechanism, relates in particular to a kind of mechanical timer unit switch.

Existing machinery formula timer only has one group of contact, and its range of application is restricted.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art to propose a kind of mechanical timer unit switch.

The purpose of this utility model is achieved by the following technical programs.

The utility model is combined by major and minor double-contact mechanical timer and two supply sockets.Described major and minor double-contact mechanical timer is the conversion hysteria double-contact mechanical timer that existing moving fault single contact mechanical timer is repacked into break-before-make, the single face moving contact that is about on the former spring leaf makes two-sided moving contact into, in inactive state and timing process, make-before-break fixed contact closure on its one side contact and the former stem, when regularly finishing, the folder in limited time that is driven its afterbody by timer spindle breaks away from latch in limited time, make the spring leaf tripping, the break-before-make fixed contact closure on its another side contact and the stem set up.Main, the compound mode of secondary double-contact mechanical timer and two supply sockets is, the two-sided moving contact of main double-contact mechanical timer is connected to the power supply phase line, its make-before-break fixed contact both was connected with the break-before-make fixed contact of secondary double-contact mechanical timer, again with first supply socket mutually line end be connected, and the break-before-make fixed contact is connected with the two-sided moving contact of secondary double-contact mechanical timer, the make-before-break fixed contact of secondary double-contact mechanical timer and second supply socket line end mutually are connected first, the zero line side of two supply sockets all is connected to zero-power line.

During actual the use, the timing TD2 that the timing TD1 that requires main double-contact mechanical timer to set sets less than secondary double-contact mechanical timer, promptly TD1＜TD2 has only when TD2=0, just allows TD1〉TD2.

The utility model cost of manufacture is cheap, and using method is easy, has wide range of applications, and is especially regularly reliable and stable, and not influenced by power failure.

The utility model has the following drawings:

Fig. 1 is an electrical schematic diagram of the present utility model;

Fig. 2 is a double-contact mechanical timer structure partial cutaway view of the present utility model.

Below in conjunction with embodiment and accompanying drawing the utility model is made an explanation.

Main double-contact mechanical timer D1 had both controlled the on/off of supply socket CZ1 and CZ2, also control the on/off of secondary double-contact mechanical timer D2, and secondary double-contact mechanical timer D2 only controls the on/off of supply socket CZ1 and CZ2, the timing of major and minor double-contact mechanical timer D1, D2 is set at TD1 and TD2 respectively, requires TD2〉TD1.

During use, at first set timing TD1 and TD2, behind the access power supply, supply socket CZ1, CZ2 are in power connection, off-state respectively, and behind the elapsed time TD1, supply socket CZ1, CZ2 change into respectively and be in power supply disconnection, on-state.And behind the elapsed time TD2, supply socket CZ1, CZ2 return to initial connection, off-state again respectively, thereby have realized the regularly function of break-make power supply.

Spring leaf 1 end of above-mentioned double-contact mechanical timer is provided with two-sided moving contact 2(A), in inactive state and timing process, make-before-break fixed contact 3(B on its one side contact and the former stem) closure, when regularly finishing, drive pressing from both sides of its afterbodys 5 in limited time by timer spindle 4 and 6 break away from latch 7 in limited time, make spring leaf 1 tripping, the break-before-make fixed contact 8(C on its another side contact and the stem set up) closure.

Claims

1, a kind of mechanical timer unit switch comprises major and minor mechanical timer and two supply sockets, it is characterized in that:
