Abstract

The utility model relates to a time relay which comprises an output terminal, a base, a housing, an executing relay, a transformer, a digital display board and a dial switch. The utility model is characterized in that by improving the inserting mode of a numerical code display panel and a dial switch and selecting large scale integrated circuit block to substitute an element with single function, the circuit board is arranged in parallel corresponding, in this way, the volume is reduced by 2-3 times as compared with similar products, structure is still more compact, and the operating anti-interference ability is more high. The utility model is particularly suitable for a machine tool circuit or an automatic control circuit.

Description

Time relay

The utility model relates to the low-voltage electrical apparatus field, particularly a kind of time relay that improves internal structure.

The existing time relay, though auxiliary groups such as display panel and time are provided with are housed, has the function that the time of implementation shows and is provided with, but because display panel and time are provided with the output pin of auxiliary group all is to draw from afterbody, and the installation site of terminal block is the back of letting nature take its course to follow at the output pin, also be welded with many electronic components on the terminal block, thereby cause the overall dimension of the time relay bigger, internal structure is staggered complicated.In addition, the integrated package of the simple function on the terminal block is many, reaches the 7-8 piece, thereby has also taken bigger space, makes the relay volume bigger, Installation and Debugging inconvenience, and interference free performance is poor, and reliability is low.

The purpose of this utility model is to overcome the weak point of above-mentioned technology, provides a kind of not only multiple functional but also time relay that volume is little by improving internal structure.

The purpose of this utility model is achieved by the following technical solution: the time relay comprises lead-out terminal, base, shell, execution relay, transformer, digital display panel, toggle switch, two wiring boards that are parallel to each other are arranged on the direction perpendicular to base, shell is pressed close in the bottom of wiring board, the output pin of toggle switch is drawn from self side, directly be inserted on the wiring board, directly be inserted on the wiring board behind crooked 90 ° of the output pin of digital display panel, have only an extensive integrated package, and patch on wiring board.

Because digital display panel and toggle switch adopt the mounting means of directly pegging graft, and have saved a large amount of mixed and disorderly connecting lines, and the wiring board arranged parallel, each parts utilizes the space as far as possible, and arrangement of elements is in picturesque disorder, makes compact conformation, rigorous, saved a large amount of spaces, reduced volume.In addition, substituted the single 7-8 piece integrated package of original function with an extensive integrated package, it is many that the more complete and overall dimension of relay function is reduced, and interference free performance strengthens, and Installation and Debugging are convenient.Therefore, compare with original time relay, the utility model be a kind of more practical, range of application is wider, the relay of superior performance.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the arrangements of elements figure of wiring board 12 among Fig. 1;

Fig. 4 is the arrangements of elements figure of wiring board 11 among Fig. 1;

Fig. 5 is 4 a schematic diagram among Fig. 1;

Fig. 6 is the left view of Fig. 5.

See figures.1.and.2, present embodiment is made up of the indicator light 9 on shell 13, base 1, lead-out terminal 10, the panel, reset button 3, functional switch 8, digital display panel 4, toggle switch 5 etc.Carry out relay 6 and be plugged in (as shown in Figure 3) on the wiring board 12 near transformer 7 with toggle switch 5, the output pin of toggle switch 5 is drawn from self side and directly is inserted on the wiring board 12; Digital display panel 4, extensive integrated package 2 and other electronic component are welded in (as shown in Figure 4) on the wiring board 11, and the output pin of digital display panel 4 changes single 12 pin into by double 24 pin, and (as shown in Figure 6) behind crooked 90 ° of the output pin just inserted on the wiring board 11; Two wiring boards 11,12 are parallel to each other and perpendicular to base 1, shell 13 is pressed close in the bottom of wiring board 11,12.

During present embodiment work, can at first lead-out terminal 10 be inserted in the respective socket, energized, indicator light 9 is bright, presses the class that functional switch 8 is selected time-delay again, present embodiment is divided into 0.1 second, second, divide, hours 4 grades, corresponding 4 toggle switchs, selectable reference time delay was from 0.1 second--and 1999 hours, after seclected time, large scale integrated circuit 2 is delivered to various signals respectively digital display panel 4, is carried out relay 6, reaches with the operating state that shows relay and presses each contact of setting-up time break-make.If necessary, can press return-to-zero button 3, the set time is reset or suspends relay work.Its circuit theory and prior art principle are similar.But compare with similar products at home and abroad, volume reduces 2～3 times.

Claims

1, a kind of time relay, comprise lead-out terminal (10), base (1), shell (13), carry out relay (6), transformer (7), digital display panel (4), toggle switch (5), it is characterized in that: two wiring boards that are parallel to each other (11,12) are arranged on the direction perpendicular to base (1), shell (13) is pressed close in the bottom of wiring board (11,12), the output pin of toggle switch (5) is drawn from self side, directly be inserted on the wiring board (12), be plugged on the wiring board (11) behind crooked 90 ° of the output pin of digital display panel (4); Have only an extensive integrated package (2), and patch on wiring board (11).
