Abstract

The utility model discloses a converted connecting and inserting piece for power sources, which is a power source inserting and connecting device universally used for various two-foot, and three-foot power sockets and plugs. The utility model has or does not have an additional protective ground connector. A current carrying pin and a current carrying sheet, the shafts of which are parallel, are connected with the sliding match work of a socket. The utility model is provided with a plurality of pins groups which are connected in parallel and jacks. Turnover grounding pins are arranged among the pins groups or in the crossed positions of the pins groups, and six inserting forms can be formed by matching with circular pins and sheet pins which can be rotated in an axial mode. The problem of matching connection of the existing various power sockets and plugs is solved.

Description

The power source conversion connector

The power source conversion connector is an interconnective device between a kind of multiple bipod that is common to same current capacity, tripod supply socket, the plug; be to be with or without the connection of supplementary protection ground connection, and have two axle current-carrying pin, sheets parallel to each other to be slidingly matched being connected of work with socket.Be mainly used in being connected between electrical equipment and the power supply.

Mostly existing power supply general connector is to be provided with the various jack of many groups.The pin of the bag plug-in source plug that also has and the metal jack and the housing of supply socket, pin and jack are formed one group or array respectively, every group of pin connects with the corresponding one by one conduction of each group metal jack, and wherein grounding pin removably links to each other with housing by helicitic texture.The universal plug of No. 88211004.7 bulletins of Chinese patent application specification on September 20th, 1989, two inserted sheets that are bipod or three-pin plug can rotational angle, inserted sheet becomes whole rotating cylinder to put into the guide hole of housing guide hole plate with a plastic cylinder, end that grounding insert-pin is porose and the stator on the housing rotate riveted joint.When not using grounding insert-pin, insert in the turning groove of going into housing of ground inserted sheet.These conversion connectors can be two, three kind socket, plug conversion pegged graft, but the socket of existing market power supply output has six kinds, appliance plug commonly used also can have six kinds of forms, these conversion connectors also have can not change grafting between more kinds of, the plug of electrical equipment can not be inserted on the socket of being run into as a rule easily use.

The purpose of this utility model is to solve between supply socket and the plug of a great variety, is difficult for pegging graft mutually, and a kind of power source conversion connector that can be connected between multiple plug, socket is provided.

Power source conversion connector of the present utility model still is made up of the pin that housing and back segment pass the housing connecting hole.Two pin back segment cylinder axis of sheet pin group still are connected with housing one side shaft hole.Its design feature is: two pins of circle pin group in the parallel connection of housing opposite side; Housing has jack, and correspondence is parallel with the jack guide card; Between circle pin group, the pin position, sheet pin winding ground or the intersection pivot pin connecting the upset grounding pin.The grounding pin of front and back upset can be turned to sheet pin group, circle pin group respectively, as the grounding pin of circle pin group or sheet pin group, forms three-pin plug.Grounding pin turn over from the time, two pins of circle pin group or sheet pin group are separately as two-pin plug.Two pins that cooperate the sheet pin group of changeable angle like this can form the plug of six kinds of forms, are inserted in easily on corresponding six kinds of sockets.It is multi-form that the jack of power source conversion connector can be provided with many groups, and the appliance plug of same form just can be inserted in corresponding jack.The power source conversion connector can conveniently combination in any connection between multiple plug, socket.Certainly also can directly be connected the electrical equipment lead on the power source conversion plug-in unit, the plug of power source conversion connector as electrical equipment.

The upset grounding pin can be sheet pin or circle pin, and the rear end is an axis hole, is enclosed within pivot pin.Pivot pin can overlap upset ground connection circle pin and upset ground strip pin side by side.Grounding pin can have two positions in one group of pin, and they are in other laterally zygomorphic two positions of two pin line perpendicular bisectors.Two upset grounding pins can be set respectively up and down, and one is the sheet pin, and one is the circle pin.Two grounding pins can connect with conductor.Upset grounding pin rear end can be connected housing or fixing guide card by axle, straight pin, screw, rivet etc.Upset grounding pin position and upset the shell position of process have groove.Preferably use guide rod in parallel between two pins of circle pin group and two pins of sheet pin group, have guide rod as two circle pin rear ends, guide rod does not hold correspondence to dock with the rear end of two pins.Circle pin and sheet pin can fuse with guide rod, also can form butt joint in relative rotation.Sheet pin rear end is preferably with cap, and cap sleeve is at the end of circle pin rear end guide rod.Guide rod can in parallelly overlap the then parallel connected end of jack guide card.Can have the multi-form jack of many groups at housing, to adapt to existing six kinds of plugs.The tripod jack can be set, and the jack aperture is greater than the width with current capacity sheet pin, and jack is fitted with flexible guide card, patches circle, two kinds of pins of sheet to adapt to.The tripod jack also can insert the plug of two pins.Many group jacks can be for the use of pegging graft simultaneously of the plug of a plurality of electrical equipment, and are very convenient.The pivot pin position of upset grounding pin rear end is not in the fixedly connected position of existing three-pin plug grounding pin, is not to be positioned at the link position of respectively organizing pin, but between each pin position, winding ground or the position of vertically intersecting, each pin position, winding ground.The upset grounding pin just can be turned to the position of each winding ground pin, as the grounding pin of each group.For the pin that wouldn't use is not exposed on the outside, housing has the insulation cover cap, covers around the pin that wouldn't use, to guarantee safety.The insulating cover cover tape has the transition bayonet socket, is stuck in housing.

Power source conversion connector of the present utility model is compared with existing power supply general connector has following advantage:

1. can make between more kinds of plugs, the socket to interconnect, the plugs and sockets of existing six kinds of forms is interconnected arbitrarily.Brought convenience for the electrical equipment use of various plugs.

2. the upset grounding pin can reduce part respectively as the grounding pin of each group, simplifies the structure.Use also more convenient, safe and reliable.

In the accompanying drawing, Fig. 1 has represented a kind of power source conversion connector package assembly schematic diagram of the present utility model, and Fig. 2 is inside and outside pin, jack guide card and a connector structural representation of its housing.

Further specify the utility model below in conjunction with the accompanying drawing example, power source conversion connector shown in the drawings is made up of hexahedral plastic casing and the pin, jack guide card and the connector 19,34 that are assembled in housing.Two panels 2, the 8 middle part same positions that plastic casing is relative have two connecting holes 10, respectively have U-shaped up and down and lack 3.The rear end is threaded the connecting hole of two round pins 1 insertion one panels 2 of guide rod 19, clamps with nut 20.The sheet pin 11 that two back segments are with nylon ladder cylinder axis passes the connecting hole of another panel 8 from the inboard, with the connecting hole interference fits, can rotate in connecting hole under external force, to change the relative angle of two pins.Sheet pin rear end has the conical cap 29 of open type, contacts with the terminal 28 pairs of covers of threaded guide rod.Accompany dividing plate 5 between the two panels, and be connected in series with bolt 12.The
