Abstract

The utility model relates to a contact spring sheet for a double timed multipurpose timer, which comprises a power supply contact spring sheet (5), a load contact spring sheet (11) and an electric motor contact spring sheet (7) and is characterized in that an action contact spring sheet (6) is arranged, one end of the action contact spring sheet is connected with the electric motor contact spring sheet (7), and a contact (4) on the other end corresponds to a contact (3) on the power supply contact spring sheet (5). The improved contact spring sheet for a double timed multipurpose timer has the advantage that the timer keeps the prior performance and adds stability so that the service is reliable and is more convenient for manufacture and application.

Description

Contact spring sheet for double timed multipurpose timer

The utility model relates to the improvement of the contact reed that a kind of plesichronous multipurpose timer uses, (application number is 91215445.4 to the patent plesichronous multipurpose timer that is proposed by me, 91230864.8, ZL9221523.3.0 ZL92215232.2) applied, but find that in making and using original contact reed is higher to material property and manufacturing assembly precision, the contact contact stabilization is relatively poor, owing to when the dynamic duty of inside recess wheel, require two contact points on the reed of motor contact to have better elastic and dimensional stability with the load contact reed simultaneously, thereby the wayward stable performance that might influence the plesichronous multipurpose timer in manufacturing and assembling.

The purpose of this utility model is in order to overcome the weak point of former patent plesichronous multipurpose timer upper contact reed, and it is easily manufactured to be used in the stable performance of plesichronous multipurpose timer upper contact reed.

The technical solution of the utility model is that the contact reed that a kind of plesichronous multipurpose timer is used has a power contact and load contact reed and motor contact reed, it is characterized in that having one one end to be connected, other end upper contact and the corresponding action of power contact reed upper contact contact reed with motor contact reed.

The utility model embodiment is further specified in conjunction with the accompanying drawings.

The contact reed schematic diagram that Fig. 1 uses for the plesichronous multipurpose timer;

Fig. 2 arranges schematic diagram for the contact reed that the plesichronous multipurpose timer is used;

Contact reed state diagram when Fig. 3 is plesichronous multipurpose timer initial condition;

Contact reed state diagram when Fig. 4 is load of plesichronous multipurpose timer and power supply normal open state;

Fig. 5 is contact reed state diagram when inside recess is taken turns dynamic duty on the plesichronous multipurpose timer;

Fig. 6 is contact reed state diagram when dynamic duty is taken turns in the evagination hole on the plesichronous multipurpose timer.

Shown in Fig. 1,2, new improved dual timer contact reed and former design are provided with relatively that one one end is connected with motor contact reed 7, other end upper contact 4 and power contact reed 5 upper contacts 3 corresponding action contact reeds 6.With former design in addition 2 points of having any different, the first on former motor reed 7 corresponding to action contact reed 6, one fulcrum piece 4 is set, and it two is provided with one one end and is connected with load reed 11, other end upper contact 2 and the corresponding normal open load of power contact reed 5 upper contacts reed 1.

Operation principle to the contact reed after improving is summarized as follows that by shown in Figure 3, dual timer is in initial condition, load 14 and timer motor 15 equal no powers.By shown in Figure 3, when dual timer was in load 14 with the power supply normal open state, power contact reed 5 upper contacts 3 contacted with load normal open reed 1 upper contact 2, made load 14 and power supply normal open state, motor 15 no powers, and timer is not worked.By shown in Figure 5, (timer is in load energising work to the time range of cutting out that regularly has a power failure) power contact reed 5 upper contacts 3 contacted with the contact 4 of moving on the contact reed 6 when inside recess was taken turns 13 dynamic duties on the plesichronous multipurpose timer, because motor contact reed 7 one ends are connected with action contact reed 6 one ends, other end upper contact 10 is in contacted normally off with load contact reed 11 upper contacts 9, makes time motor 15 and load 14 all be in the energising operating state.By shown in Figure 6, when on the plesichronous multipurpose timer during 12 dynamic duties of evagination hole wheel (in the time range that timer begins regularly to connect to load) power contact reed 5 upper contacts 3 contact with the contact 4 of moving on the contact reed 6, and push motor contact reed 7 open by the fulcrum piece 8 that acts on the motor contact reed 7, contact 10 is separated with the contact 9 of load contact reed 11, make time motor 15 be in the energising definition status, and load 14 no powers have been finished plesichronous work like this.All the other operation principles of the utility model are the same with former patent application, no longer explain.

The utility model has the advantages that by improving the contact reed of Double timed multi-purpose timer, make more reliable, the manufacturing of being more convenient for of Double timed multi-purpose timer work.
