A kind of terminal board preventing mis-wired
Technical field
The utility model relates to O&M security technology area, is specifically related to a kind of terminal board preventing mis-wired.
Background technology
Connect in line at electrical production protection screen, in screen, equipment is will by some special binding posts with shielding that external equipment is electrically connected, and these binding posts combine and are called terminal board.The effect of terminal board is coupled together the line electricity of the circuit of equipment in screen with screen external equipment, plays signal of telecommunication transmission effect.When carrying out wiring to terminal board, by observing the wiring of terminal row wiring number check mark, because terminal row wiring number mark is not remarkable, often can there is the phenomenon of wiring dislocation, causing serious consequence in wiring personnel; Disclose a kind of protection screen terminal board with light-emitting diode prompting at CN204597005U, solve the inapparent problem of existing protection screen connecting terminal block number mark.Be included on terminal board body and be fixedly installed terminal block, terminal junction box is provided with in terminal block, the top end face of the terminal block in the outside in fastening jackscrew hole is fixedly installed fastening jackscrew passage cylindrical shell, fastening jackscrew is screwed onto in fastening jackscrew hole by fastening jackscrew passage cylindrical shell, normal open switch is provided with in the middle part of the madial wall of fastening jackscrew passage cylindrical shell, terminal block is respectively arranged with light-emitting diode group and button cell, and light-emitting diode group, button cell and normal open switch connect to form closed circuit; Although it is provided with prompting, still do not solve the phenomenon that can prevent mis-wired, but not yet solve the technical scheme of this problem at present.
Utility model content
Problem to be solved in the utility model is to provide a kind of terminal board preventing mis-wired, can not only meet and plug needs normally, and can solve the phenomenon of mis-wired.
To achieve these goals, the technical scheme adopted is:
A kind of terminal board preventing mis-wired, comprise terminal board body, described terminal board body arranges some interfaces, described interface arranges the lid being used for closing described interface, described interface week, side arranged coding groove, and described lid realizes opening with closed by the push switch in coding groove.
Described interface outer setting Signal aspects lamp, the switch-linear hybrid of described Signal aspects lamp is at interface internal lower surface.
The shape of described push switch and the mating shapes of coding groove.
The joint that described interface is arranged, the pressing key that the sheathed and corresponding groove of encoding of its avris matches.
Described joint arranges the step matched with described pressing key.
Described push switch comprises block and button, and described button rear portion is arranged in the mounting groove on described interface top by Compress Spring, and described block is arranged on button front end and is connected with interface top movable by torque spring.
Described button is H type.
The utility model, for existing terminal board, arranges lid at interface, and by the switch-linear hybrid of lid in the coding groove of interface week side, and coding groove can be arranged on different orientation for different interfaces, the effect distinguishing numbering can be played; And interface and joint are routine techniques, only adding at interface needs the pressing key of the shape of corresponding coding to open, and the pressing key adopted is arranged on the step place of existing joint by sheathed mode, it is made to form the joint of reference numeral, if the pressing key of not sheathed reference numeral, then joint can not inject in interface due to the stop of block, thus realizes the phenomenon preventing wrong plug.
In addition, stopping of employing is installed by torque spring, can the power of supplying the steadying hand be closed by lid, and button is set at its rear portion, stable support force can be provided to it, thus ensure when there is no pressing key trigger key, lid be stablized and is in sealing state.
In addition, at interface outer setting Signal aspects lamp, and by switch-linear hybrid at interface internal, when terminal board body inserts joint without any interface, then Signal aspects lamp is and lights, if after inserting joint in the interface of correspondence, then Signal aspects lamp extinguishes, make the normal interface connected send normal signal blinking light, the interface do not inserted then shows color or the sequence number of this interface reference numeral; This design makes the interface of non-connection-peg become very remarkable, can make operator from interface in a row, easily find out corresponding interface.
The utility model is coordinated with the dual of Signal aspects lamp by coding groove, can not only the looking for fast of convenient operation person, and can realize the generation of misoperation, and structure is simple, easy and simple to handle, is worth application and popularization.

Embodiment
Below in conjunction with accompanying drawing 1-4, the utility model is further detailed:
Embodiment one: a kind of terminal board preventing mis-wired, comprise terminal board body 1, described terminal board body 1 arranges some interfaces 2, described interface 2 place arranges the lid 4 being used for closing described interface, described interface 2 weeks sides arrange coding groove 3, and described lid 4 realizes opening with closed by the push switch in coding groove 3.
Described interface 2 outer setting Signal aspects lamp 6, the switch 7 of described Signal aspects lamp 6 is arranged on interface 2 inside.
The shape of described push switch and the mating shapes of coding groove 3.
The joint 10 that described interface 2 place is arranged, the pressing key 9 that the sheathed and corresponding groove 3 of encoding of its avris matches.
Described joint 10 place arranges the step 11 matched with described pressing key 9.
Described push switch comprises block 12 and button 5, and described button 5 rear portion is arranged in the coding groove 3 on described interface 2 top by Compress Spring 8, and described block 12 is arranged on button 5 front end and is connected with interface 2 top movable by torque spring.
The shape of described button 5 is H type.
Embodiment two: a kind of terminal board preventing mis-wired, comprise terminal board body 1, described terminal board body 1 arranges some interfaces 2, described interface 2 place arranges the lid 4 being used for closing described interface, described interface 2 weeks sides arrange coding groove 3, and described lid 4 realizes opening with closed by the push switch in coding groove 3.
Described interface 2 outer setting Signal aspects lamp 6, the switch 7 of described Signal aspects lamp 6 is arranged on interface 2 inside.
The shape of described push switch and the mating shapes of coding groove 3.
The joint 10 that described interface 2 place is arranged, the pressing key 9 that the sheathed and corresponding groove 3 of encoding of its avris matches.
Described joint 10 place arranges the step 11 matched with described pressing key 9.
Described Signal aspects lamp 6 is numeral number type LED.
Using method of the present utility model: find the interface needing grafting, the then pressing key of sheathed reference numeral on joint, then injected in corresponding interface, and corresponding Signal aspects lamp is extinguished, and then confirms the signal lamp flicker in it.
Although the utility model with preferred embodiment openly as above; so itself and be not used to limit the utility model; anyly have the knack of this those skilled in the art; not depart from spirit and scope of the present utility model make an amendment, change and retouching, the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.
