Embodiment

Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit the scope of the utility model.

Fig. 1 is a kind of batch of control instrument guidance panel block diagram of the present utility model.Criticizing control instrument guidance panel includes the He of operation keyboard 1 Display device 2, operation keyboard 1 and display device 2 connect.

Fig. 2 is the operation keyboard structural representation for criticizing control instrument guidance panel in the prior art.As shown in Fig. 2 existing Criticize in control instrument guidance panel, the metal key-press 12 on key panel 11 is directly abutted by threaded rod 13 is located at operation keyboard Touch-switch 16 on PCB bottom plates 17.

Because touch-switch 16 is to realize its plunger return by the shell fragment of its own, applied to batch control instrument operating surface When in plate, if metal key-press 12 and threaded rod 13 are to be abutted straight down with touch-switch 16, due to Action of Gravity Field, Press when unclamping after metal key-press 12 again, metal key-press 12 and threaded rod 13 may not parking position accuracy, both influenceed this behaviour Make, influence subsequent operation again.Simultaneously as threaded rod 13 directly abuts with touch-switch 16, penetrated into from key panel 11 Liquid will likely corrode touch-switch 16 and operation keyboard PCB bottom plates 17.

Fig. 3 is the operation keyboard structural representation of of the present utility model batch of control instrument guidance panel, and Fig. 4 is of the present utility model Criticize the operation keyboard schematic surface of control instrument guidance panel.As shown in Figure 3, Figure 4, in one embodiment of the present utility model, Operation keyboard 1, which includes key panel 11, operation keyboard PCB bottom plates 17 and at least one button assembly, the button assembly, to be included Metal key-press 12, threaded rod 13, spring 14, rubber blanket 15 and touch-switch 16, it is provided with key panel 11 at least one Through hole, one end of threaded rod 13 are fixedly connected through through hole with metal key-press 12, the other end and rubber blanket of threaded rod 13 15 one side abuts, and the another side of rubber blanket 15 and the surface of touch-switch 16 abut, and rubber blanket 15 covers touch-switch 16, gently Touch switch 16 to be arranged on operation keyboard PCB bottom plates 17 and electrically connect with operation keyboard PCB bottom plates 17, spring 14 is sheathed on screw thread Outside connecting rod 13, one end of spring 14 and key panel 11 abut, and the other end and rubber blanket 15 of spring 14 abut, PCB bottom plates 17 Electrically connected with display device 2.

Specifically, different literals or symbol can be set in the different zones of key panel 11, to indicate the work(of respective metal button Energy.Through hole on key panel 11 can be configured according to being actually needed, such as be arranged to 3 rows 3 and arranged totally 9 through holes, right respectively 9 button assemblies are answered, set 9 button assemblies to correspond to digital 1-9 respectively, and are identified on key panel 11, by dividing Not An Ya metal key-press 12, display device 2 will show digital 1-9 respectively.

Metal key-press 12 and threaded rod 13 are threadably secured connection, when metal key-press 12 is pressed, pass through screw thread The abutting of connecting rod 13 and rubber blanket 15, touch-switch 16 will also be pressed, so as to realize the connection of related circuit.Internal diameter is more than spiral shell The spring 14 of the external diameter of line connecting rod 13 is sheathed on outside threaded rod 13, and the natural length of spring 14 is more than the length of threaded rod 13, After spring 14 is sheathed on into 13 outer of threaded rod, one end of spring 14 and key panel 11 abut, the other end and rubber blanket 15 abut, and now spring 14 is in compressive state.When metal key-press 11 is released, on the one hand, the bullet of itself of touch-switch 16 Piece will realize the plunger return of touch-switch 16, and on the other hand, the spring 14 of compressive state also can drive gold by negative drawing Category button 12 and threaded rod 13 reset.

Meanwhile rubber blanket 15 is additionally provided between threaded rod 13 and touch-switch 16, rubber blanket, which completely covers, to be touched Switch 16.When there is liquid to be penetrated into from the through hole of key panel 11, rubber blanket 15 can make touch-switch 16 shadow such as not weather Ring.

Preferably, if operation keyboard 1 includes multiple button assemblies, have on operation keyboard PCB bottom plates 17 multiple light Switch 16 is touched, now rubber blanket 15 is an entirety, not only covers each touch-switch 16, is also covered between each touch-switch 16 The part of operation keyboard PCB bottom plates 17.

Fig. 5 is the pcb board attachment structure schematic diagram for criticizing control instrument guidance panel in the prior art.Operated in existing batch of control instrument In panel, if LCD display and touch-switch array are located on same pcb board, cloth can be carried out on one piece of PCB Line, if LCD display and touch-switch array are not located on same pcb board, as shown in figure 5, display device PCB bottom plates 22 Connected with operation keyboard PCB bottom plates 17 by socket pin 31.

Being connected by socket pin 31, structure may be relatively more firm, but because the socket pin of side is insertion opposite side Socket hole, if as reasons in structure, socket pin can not fully-inserted socket hole, although the two still has Metal contacts Point, but after long-time use, situations such as having oxidation unavoidably and corrode, cause between operation keyboard 1 and display device 2 Stable signal transmission declines.Further, since structure is relatively fixed, the problem of there is also spatial spread between each part is not suitable for.

Fig. 6 is the pcb board attachment structure schematic diagram of of the present utility model batch of control instrument guidance panel.As shown in fig. 6, display dress Putting 2 includes LCD display 21 and display device PCB bottom plates 22, and LCD display 21 is arranged on display device PCB bottom plates 22 simultaneously Electrically connected with the display device PCB bottom plates 22, display device PCB bottom plates 22 and operation keyboard PCB bottom plates 17 pass through winding displacement 32 Electrical connection.

Specifically, due to the better tightness of winding displacement, and length can adjust, flexible also bigger, and prior art phase Than after the socket pin 31 of connection is replaced by into winding displacement 32, can not only ensure the letter between operation keyboard 1 and display device 2 Number transmission stability, while be also convenient for according to the actual requirements being adjusted the relative position between operation keyboard 1 and display device 2 It is whole.

Preferably, display device 2 also includes processor and communication chip, at LCD display 21 and communication chip electrical connection Manage device.

Specifically, display device 2 can be carried out by processor and communication chip and ambient systems, such as PLC control system Interactive connection, improve the function expansibility of batch control instrument guidance panel.

Provided by the utility model batch of control instrument guidance panel, enable the metal key-press parking position accuracy on key panel, and The contact-making switch on PCB bottom plates is protected, while can ensure that the stable signal transmission between display device and operation keyboard connects.

Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in Within the scope of shield.
