Abstract
The utility model discloses a single phase two poles positioning plug-in unit. The present single phase two poles power supply plug and socket don't distinguish between the zero wire and the fire wire of the power supply so as to easily cause an electric appliance to leak electricity after the electric appliance is turned off and shorten the service life of the devices of the electric appliance. The utility model is the single phase two poles positioning plug-in unit, the inserting holes of the socket are composed of a flat-square hole and a flat-round universal hole, and a plug is composed of a flat-square pin and a long cylinder pin. So when the plug and the socket are plugged, the single phase two poles positioning plug-in unit realizes the positioning plug-in so as to eliminate the leaking phenomenon of the electric appliance after the electric appliance is turned off and simultaneously raise the standardizing degree of the power supply plug-in unit.
Description
The utility model belongs to electrotechnical apparatus.
Single-phase two utmost point power connectors that present institute produces and uses, be single phase alternating current power supply plug, socket, do not distinguish for live wire and zero line, often think that alternating current needs strictly to distinguish positive and negative electrode unlike direct current, thereby ignored live wire and zero line location in use connects.Because most appliance switches are the single line switch, often after electric equipment cut out, electrical equipment inside was still charged, thereby caused the generation of electric leakage accident.The aging of components and parts quickened in glow discharge meeting after closing as fluorescent tube, and power consumption is also shortened its useful life.Now though two-wire safety-type switch is arranged, avoid electrical equipment closing the back electric leakage, but because its structure is complicated, the cost height, and be difficult to large-scale popularization use in electrical equipment.
The purpose of this utility model provides a kind of single-phase two utmost points location connector, realizes that the location of live wire and zero line connects, thereby eliminates the leaky after electrical equipment cuts out, and take compatible design, and the old and new's device can compatiblely be used.
This single-phase two utmost points location connector is achieved like this, and one of two jack of its socket are flat square holes, and another is a circular port, and the live wire of flat square hole and power supply joins, and circular port and zero-power line join; One of two pin of plug are flat side's pin, and another is the cylinder pin, and the end that insulation property are high in flat side's pin and the electrical equipment is connected, and the end that insulation property are low in cylinder pin and the electrical equipment is connected.When plug insertion socket, just form the location and connect.Be live wire can only connecting circuit in the high end of insulation property, after electrical equipment cut out, leaky no longer took place in electrical equipment.To use in order solving, the circular port of socket can be changed into oblate general hole, thereby also can use two flat side's n pin package ns with the compatibility of existing connector.Zero line is connected earlier when patching for making, and to improve the security appliance performance, can make plug cylinder pin be longer than flat side's pin slightly.For this connector is conformed to national standard, and use with the primary standard part is compatible, the flat utmost point of this location connector receptable and plug and the centre-to-centre spacing of the circular utmost point can be designed to the 13-16 millimeter, the diameter of plug cylindrical pin is the 3-5 millimeter.
This single-phase two utmost points location connector is owing to realized the location grafting of plugs and sockets, prevented from effectively to leak electricity after electrical equipment from cutting out, improved the coefficient of safety of electric equipment, prevented the aging and energy waste of the appliance component that causes by electric leakage, also be convenient to power line is carried out color separation processing etc.Improved the standardization level of power connector.Owing to adopt compatible design, also can satisfy being used alternatingly of excessive the old and new's device in period simultaneously.
Description of drawings.Fig. 1 is single-phase two utmost point positioning socket schematic diagrames, and wherein (1) is flat square hole, and (2) are oblate general hole; Fig. 2 is single-phase two utmost point polarized plug schematic diagrames, and wherein (3) are flat side's pin, and (4) are the cylinder pin.
Best implementation of the present utility model is: socket, and 12.7 millimeters of the flat square hole centre-to-centre spacing in flat square hole and oblate general hole, the circular port centre-to-centre spacing in flat square hole and oblate general hole is 14.7 millimeters; Plug, long 16 millimeters of flat side's pin, wide 6.3 millimeters, thick 1 millimeter, long 21 millimeters of cylinder pin, 4 millimeters of diameters, flat side's pin and cylinder pin centre-to-centre spacing are 14.7 millimeters, and the design's polarized plug socket and standard GB 1002-67 and GB1003-67 regulation keep certain compatible.
