Abstract
The utility model is related to mahjong machine technical field; disclose a kind of safety switch control circuit of mahjong machine; switched with ship type using the switch security of button switch and relay substitution prior art; work as circuit abnormality; such as voltage or electric current is excessive, short circuit when; insured by double-break; live wire and zero line are cut off simultaneously; the control circuit of safer protection mahjong machine; simultaneously by the pre-set programs control relay of mahjong machine control mainboard, delayed-breaking-off function is capable of achieving, when mahjong machine never has operation; time delay is automatically powered off, and prevents hidden danger；Using with the connecting plate for installing buckle and mounting post, it is integrally connected relay and button switch are compact, save space is easy to repair；By above measure, the security of the larger mahjong machine control circuit for improving prior art of the utility model.
Description
Technical field
The utility model is related to mahjong machine technical field, more particularly to a kind of safety switch control circuit of mahjong machine.
Background technology
In existing mahjong machine control circuit, mahjong machine on-off circuit is generally made up of switch security, ship type switch, external
Transformer, control mainboard inside mahjong machine constitute the main body switch control circuit of mahjong machine, but this kind of simple switch control
Circuit has larger potential safety hazard, and switch security can only realize that single channel is insured, i.e. circuit abnormality, such as voltage or electric current mistake
Greatly, during short circuit, switch security by the live wire or zero line of line disconnection realize safety precaution act on, and it is actually used in,
Only cut-out live wire could realize security protection or so, if but install wiring when switch security wiring when live wire it is reversed with zero line,
Circuit abnormality cuts off zero line, however it remains second short circuit even circuit potential safety hazard on fire.
The content of the invention
The utility model proposes a kind of new peace for the not enough defect of mahjong machine control circuit security in the prior art
Full switch controls circuit.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
One button switch and relay substitution switch security are switched with ship type, work as circuit abnormality, such as voltage or electric current it is excessive,
During short circuit, insured by double-break, while live wire and zero line are cut off, the safer control circuit for protecting mahjong machine, together
When by the pre-set programs control relay of mahjong machine control mainboard, delayed-breaking-off function is capable of achieving, when mahjong machine never has
During operation, time delay is broken automatically, prevents hidden danger.
As preferred：It is connected by electric wire with road relay to solve button switch, is positioned over inside mahjong machine, easily
Generation wire intertwist, the problem of repair and replacement inconvenience, the utility model, will using the connecting plate with installation buckle and mounting post
Relay is compact with button switch to be integrally connected, save space, is easy to maintenance.
The utility model as a result of above technical scheme, with significant technique effect：Circuit control is safe and reliable,
Compact conformation rationally, is easy to maintenance and installation.
Brief description of the drawings
Fig. 1 is the assembling figure that button switch of the present utility model is assembled with relay by connecting plate.
Fig. 2 is the connecting board structure front view in Fig. 1.
Fig. 3 is the three-dimensional view of the connecting board structure in Fig. 1.
Fig. 4 is circuit interconnect pattern of the present utility model.
The toponym that each number designation is referred in accompanying drawing is as follows：1- button switches, 2- connecting plates, 21- mounting posts,
22- installs buckle, 3- relays, 31- relays mounting hole, 4- power supplys, 5- mahjong mainboard, 51- speech interfaces, 52- fans
Interface, 6- binding posts, 7- transformer wiring terminals.
Specific embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1 to 4, the safety switch control circuit of a kind of mahjong machine, including power supply 4, button switch 1, mahjong
Mainboard 5, relay 3, transformer wiring terminal 7, wherein mahjong mainboard 5 are provided with speech interface 51, fan interface 52, circuit
Connected mode is connected with power supply 4, relay 3 respectively for the terminals of button switch 1, relay 3 also with speech interface 51, fan
Interface 52 is connected, and using the security of button switch, two point controls the live wire and zero line of main circuit, double on and off, while passing through
The pre-set programs control relay of mahjong machine control mainboard, can realize delayed-breaking-off function.Circuit wiring group dress also includes simultaneously
Connecting plate 2, button switch 1 is connected with relay 3 by connecting plate 2, and connecting plate 2 is fastened on button switch by installing buckle 22
On 1, relay 3 is fixed in mounting post 21 by screw through relay mounting hole 31, compact conformation safety.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute
The impartial change of work and modification, should all belong to the covering scope of the utility model patent.
