Abstract

The utility model relates to a resisting surge current plug and socket fixed by the connection, and belongs to the field of power supply plug and socket. The surge current resisting plug and socket includes a plug comprising a main structure composed of a wide inserting piece, a narrow inserting piece, a wire port and a thermistance, and a socket comprising the main structure composed of a wide faucet corresponding to the wide inserting piece, a narrow faucet corresponding to the narrow inserting piece and the thermistance. The utility model produces a wide structure and a narrow structure between the inserting piece or an inserting pole of the plug without positional correspondence which is widely used at present and a plug jack of the socket in a respectively corresponding way; a high potential line and a low potential line of a power supply are respectively fixed and electrically connected with corresponding connection pin of the plug and the socket; the inset is completed only when connecting correctly, thereby ensuring the correct and stable connection between the power supply and each electrode of appliances; the two grading thermistance replaces a fuse and clips peak the resisting surge current in a grading way, therefore, the utility model has the great value of safe power utilization, convenient use, simple and easy operation and wide application and market prospect.

Description

Wiring is Antisurge current plug and socket fixedly

Technical field:

The utility model belongs to power supply base and plug field.

Background technology:

One of alternating current and galvanic notable feature are the branches that the former does not have positive and negative electrode, the substitute is fire, ground wire, but the two from the high and low of current potential and the opinion then similar, promptly positive pole or live wire are that high potential, negative pole or ground wire are electronegative potentials; Also similar from the loop analysis of forming circuit, promptly positive pole or live wire are that outlet, negative pole or ground wire are inlet wire or loop line for power supply, and be then just the opposite with respect to electrical appliance.Therefore, many general character and extremely important to safety utilization of electric power and operate as normal are arranged also between the two class power supplys,, high and low current potential difference is arranged, otherwise equally easily be damaged though do not have the positive and negative electrode requirement as many capacitors.In actual applications, DC power supply is because of must distinguish and fix the positive and negative electrode wiring of they and electrical appliance in advance, could drive electrical appliance and self normal and trouble free service, so just the positive and negative electrode wiring is fixed during in advance as manufacturing or installation, AC power also has similar safety utilization of electric power requirement and regulation.Yet to using extremely extensively and the AC power of enormous amount and in fact be the socket and plug that the AC and DC power supply all can be general, present product is difficult to all generally ensure that it buries many major hidden dangers with permanent correct the fixedlying connected of the high and low current potential of electrical appliance to safety utilization of electric power.Such lesson is a lot, sometimes or even very serious as fatal, cause great permanent disability etc., as because of plug to the freedom of socket and jack position thereof repeatedly conversion cause shell such as many household electrical appliances such as TV or sole plate metal is charged and use damage and use and maintenance personal's electric shock and injures and deaths with maintenance, because of thunder and lightning and circuit are opened, the powerful destruction of surge currents such as pass or excess load and short circuit need artificial replacing or maintenance just can restore electricity after burning fuse, and often, all should be paid much attention to and be properly settled because of not having suitable even not having fuse to use the dangerous and inconvenient problem of electricity consumptions such as wire replacement.

Summary of the invention:

The purpose of this utility model provides a kind of wiring fixedly Antisurge current plug and socket, with solve above-mentioned because of plug and the high electronegative potential wiring of socket fixing and surge current and change fuse cause electricity consumption dangerous with Electrical Safety potential problem such as inconvenience.

The technical scheme in the invention for solving the technical problem is: will not have the inserted sheet of plug of position correspondence or the jack of inserting column and socket and all manufacture to correspondence a wide narrow structure respectively, the high and low equipotential line of power supply fixedly is connected electrically in respectively on the leg of corresponding with it socket or plug; Series thermal-sensitive resistance on an electrode of plug and socket respectively.

The beneficial effects of the utility model are: design all manufactures to correspondence a wide narrow structure respectively with the inserted sheet of the plug of present widely used no position correspondence or the jack of inserting column and socket, when the jack of the inserted sheet of plug or inserting column and socket by correspondence when manufacturing a wide narrow structure, have only patching just of same correspondence to inject, so just only need height with power supply, the electronegative potential line fixedly is connected electrically in respectively can be finished and ensure on the leg of corresponding with it socket or plug and correctly patch and fool proof, and product uses not only very convenient, make and also need not to increase any operation and cost substantially and simple; Inserted sheet and jack divide width to make the differentiation and the application of height equipotential line become easy, feasible, embodied thereby make such as serial great practical significances such as safety utilization of electric power and use value, and easily standardization and standardization, thereby realized more and more by the highest goal of all trades and professions confessed " standard is sold by first-class enterprise "; Series thermal-sensitive resistance can anti-respectively overcurrent be surge (peak value) electric current and infringement thereof just on an electrode of plug and socket respectively; air; the instant cut-off of almost present all insurances such as electromagnetic type or switchgear all causes the impact of overcurrent to electrical appliance and electrical network; infringement and damage; a host of facts prove a lot of electrical equipment and electronic devices and components such as transistor; the damage of chip etc. is not to occur in the insurance outage as before the blown fuse; but the surge peak energy that promptly produces therefrom in the moment of blown fuse damages; cause insurance " non insurance " even play damage effect on the contrary; this product weakens the surge current peak energy because of the thermistor two-stage of connecting respectively on the electrode of plug and socket; and be translated into heat absorption and self temperature and resistance are raise; when being raised to the outage degree, cut off circuit voluntarily; only need this moment of short duration powered-down or electrical appliance switch to wait for that resistance falls in the thermistor auto-radiating; automatic recovery of power supply ability when dropping to normal degree; only need close a switch again this moment and connect circuit with regard to automatic recovery of power supply; power-off protection mechanism when overload or short circuit is identical with principle; so need not and change fuse; and because of this outage is a kind of slow time-delay continuity process; not so that instant cut-off is no surge current; coefficient of safety is very high; be the inconvenience that power supply or electrical appliance overload can not produce fire and replacing fuse; more can (this class situation is report and often endanger wide often because of power supply damages electrical appliance; suffer heavy losses) so fool proof; product uses very convenient; make and also need not to increase any operation substantially with cost and simple, so its application and market prospects are extremely wide; promptly satisfactorily finish above-mentioned utility model purpose.
