Description

One kind is easy to identify the accurate binding post of wiring

Technical field

The utility model is related to one kind and is easy to identify the accurate binding post of wiring.

Background technology

With the raising of social industrialized level and people's nontimber forest, more and more various types of household electrics Device occurs in daily life, also includes various electric equipments, such as switch board, switch cubicle, switch, instrument box, Computer, TV, air-conditioning, refrigerator, washing machine, electric automobile etc..The internal strong power part of these electric equipments is usually used and carries Two-phase or three-phase power line carry out power input, and the two-pin plug socket of China have the shortcomings that up and down regardless of.For Ensure the stable of control source and the consideration for Electrical Safety, being even more for some large power-consuming equipments needs using band There are four hole the plugs even power line of five pore area ground wire plugs although giving to mark with strongly professional English initial or symbol Know, ordinary person is easily malfunctioned or does not know how correct wiring in wiring, wiring error situation easily occurs.In addition from The electric equipment of user terminal, whole circuit transmission mistake are arrived again to booster stations, transformer station, switchyard, low-tension transformer in power station Need in journey to carry out circuit switch using substantial amounts of binding post, change-over switch, fuse, arrester etc., wiring easily occurs wrong Situation by mistake.The live wire of transmission line, zero line, ground wire and phase sequence will be arranged during generating, electricity consumption or circuit switch Row are distinguish between, however selling in the market and be currently in use various types of generating equipments, potential device or The binding post of person's electrical equipment is not all effectively identified to it, is shown turnover relation and color sequence.For not yet done For knowing technical staff and the domestic consumer of relevant regulations, it is easy to that access live wire, zero line, the intersection of ground wire or phase occur The confusion of sequence arrangement, general user also cannot accurately identify live wire, zero line and name placement.And for light current multidigit connection end Son, such as military connection plugs and sockets, aviation jack, TV, computer plug socket etc. (more than 10-20 hole) assembling wiring is more held Error-prone, detection difficulty is also higher, when multiple disconnection fault, recovers difficulty greatly, especially military connection plugs and sockets is in war In the environment of field, after damage, quick reparation is extremely important.

Content of the invention

Effectively do not identified to solve existing binding post, corresponding display electric power polarity and color sequence Technical problem, the utility model provides one kind to have obvious color box mark, color lump, colour band, line pattern, numeral, direction arrow Head, color guide line or national words identification and projection are to improve the binding post of wiring accuracy.

Technical solution of the present utility model is：One kind be easy to identify the accurate binding post of wiring, include shell with Multiple terminals, described terminals are stretched out by enclosure, and it is characterized in that：Multiple marks are provided with described shell Area；Described tag slot and terminals are one-to-one relation.

Above-mentioned tag slot is in plane mark on outer surface of outer cover or inner surface, projection, groove or overall many Color is molded.

Above-mentioned tag slot is the group of one or more of color lump, colour band, direction arrow, line pattern, numeral and character Close.

Above-mentioned color lump is generally circular in shape, annulus, the color lump of square or square frame being surrounded on around terminals.

Above-mentioned colour band is the guide line connecting with one end terminals.

Above-mentioned character be " fiery ", " ", " zero ", " entering ", " going out ", " control ", " on ", D score, one of " N " and " L " or Several combinations.

Above-mentioned binding post be socket, plug, knife-like switch, air switch, breaker, ammeter, motor, connection terminal, Binding post on generator or transformer.

The surface that above-mentioned direction arrow is arranged on binding post itself or connects power line or shell.

Above-mentioned direction arrow quantity is multiple, embodies turnover relation.

Above-mentioned raised or groove is one or more, raised or groove generally circular in shape or square.

The beneficial effects of the utility model are：The utility model is in socket, plug, knife-like switch, air switch, open circuit Device, ammeter, motor, transformer, the binding post of all kinds of circuit such as power line, generator or transformer connection equipment sets Put the tag slot of easy identification, the different color of tag slot corresponding from different terminals setting and sequence, character energy side of various countries Just technical staff or domestic consumer carry out accurately distinguishing identification to the difference terminals such as live wire, zero line, ground connection, colored mark Know the power line of the corresponding different colours in area, the unification of color, phase sequence can be accomplished, can also be easily after unexpected broken string Accurately take back, ordinary person also can correctly connect.Not only increase wiring security and also increase wiring convenience, significantly Improve technical staff or domestic consumer carries out the efficiency of wiring, be also applied to the signals such as optical fiber switch, netting twine switch Transmission network.In addition, sub-thread or multiply power line setting direction arrow, display power supply trend, the band face that the utility model provides The binding post of color marker is applied to socket, insert row, plug etc., easily identifies, improves accurate wiring success rate, and two-pin plug sets Put color mark, make socket live wire accurate connecting circuit equipment fusible link end, it is to avoid lead to after fusible link fusing entirely because reversed Power circuit is powered, improves electrical safety, and especially the binding post of generator and motor has been carried out with color, position arrangement Mutually permitted to limit, that is, binding post yellow from left to right, green, red, light blue (blue), phase sequence turn clockwise, that is, be easily achieved and send out from source Motor carries out the unification of parallel transmission, tag slot color and sequence to terminal motor, and no matter centre is through how many booster stations, change Power station, switchyard, low-tension transformer, transmission circuit etc., can realize the purpose of this utility model, guide correct wiring, this reality That is, and generator after new enforcement, access the present embodiment motor in any one load end and can realize rotating clockwise, Turn to identical, also avoid existing AC three-phase A B C be equal to AC three-phase B C A and AC three-phase C B A, that is, turn to consistent and The problem of crossing elimination, by colour code area be easily achieved AC three-phase A B C is uniquely parallel or multichannel multilayer connects, therefore Barrier reports circuit for repairment accurately, is particularly suitable for underground cable and frequently transfers.

Above improvement is applied in electrical equipment such as knife-like switch, air switch, breaker, ammeter, A.C. contactor, the joints of optical fibre Turnover terminals position wire colors are defined simultaneously, then define the color of power line by the binding post of equipment And direction, serve the effect formed a connecting link, even if the wiring of domestic consumer also can reach specially with reference to color, direction arrow correspondence Industry personnel's wiring level, understand power supply trend, can specification existing product, can be widely used in electrical power control cabinet, switch cubicle, instrument In the equipment such as case, switch, advantage is power supply or signal turnover relation is clear and definite, eliminates wiring error, installation specification, domestic consumer Also operable, security greatly enhances, and is particularly suitable for battlefield clutter environment.
