Abstract
The utility model relates to a power plug, in particular to a two-core power plug with a two-phase conductor; the two-core power plug comprises a shell; a pair of conductive jacks are arranged on the end face of the shell; two pluggable conductors connected with two leads at the rear end are respectively arranged in the conductive jacks; a square hole with a square section is also formed on the end face of the shell; the square hole corresponds with the E pole of a three-core socket; and the side length of the section of the square hole is not less than the maximum length of the section of the E pole of the three-core socket. The two-core power plug disclosed by the utility model can be matched with the two-core or three-core socket in a pluggable manner and is applied to the vertical or transverse E pole simultaneously; furthermore, the E pole is allowed to have position deviation in a certain range in the thickness direction, and therefore, the precision requirement and the manufacturing cost are reduced.
Description
Technical field
The utility model relates to a kind of attaching plug, specifically a kind of two core attaching plugs with two phase conductors.
Background technology
Attaching plug has two cores and three core two class formations conventionally, the common two core attaching plugs with jack generally include a plug casing coordinating with Socket casing, on plug casing end face, be provided with pair of conductive jack (the N utmost point and the L utmost point), in conductive jack, be respectively arranged with two grafting conductors that are connected with two of rear ends lead-in wire.This two core attaching plugs can only coordinate grafting with the socket with two conduction poles, and for the socket with three conduction poles (the N utmost point, the L utmost point and the E utmost point), cannot peg graft, and have affected its scope of application.In order to improve the versatility of two core attaching plugs, existing a kind of two core attaching plugs at its housing end face except arranging pair of conductive jack, also have the dead slot of a flat rectangular matching with the E utmost point pole cross sectional shape of three core sockets, but because there is horizontally set in the cross section of the E utmost point pole of three core sockets and two kinds of versions are vertically set, the two core plug that therefore only has a direction flat rectangular groove can not adapt to all situations.In order to overcome above-mentioned defect, existing a kind of two core attaching plugs are at the dead slot that a cross section relative with the E utmost point pole of three core sockets is " T shape " or " cross " that arranges of housing, horizontal or the vertical E utmost point pole arranging with simultaneous adaptation, but the dead slot structure of this structure is more complicated, machine-shaping difficulty, requirement on machining accuracy is also higher, thereby manufacturing cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can be applicable to two cores or three core sockets, and two core attaching plugs simple in structure, required precision is low, cost is low.
Two core attaching plugs of the present utility model include a housing, are provided with pair of conductive jack (the N utmost point and the L utmost point) on the end face of housing, are respectively arranged with two grafting conductors that are connected with two of rear ends lead-in wire in conductive jack; On described housing end face, also having a cross section is foursquare square hole, and the position of square hole is corresponding with the E utmost point pole of three core sockets, and the cross section length of side of square hole is not less than the maximum length in the E utmost point pole cross section of three core sockets.
The utility model by arranging the square hole corresponding with the E utmost point pole of three core sockets on housing, thereby all can peg graft and coordinate with two cores or three core sockets, simultaneously because the cross sectional shape of square square hole is all applicable to vertical or horizontal E utmost point pole, and allow E utmost point pole at its thickness direction, to there is the position deviation of certain limit, thereby reduced required precision and manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, this two cores attaching plug includes a housing 1, is provided with the pair of conductive jack 2(N utmost point and the L utmost point on the end face of housing), in conductive jack, be respectively arranged with and two of rear ends lead-in wire 3 two grafting conductors that are connected; On described housing 1 end face, also having a cross section is foursquare square hole 4, and the position of square hole is corresponding with the E utmost point pole of three core sockets, and the cross section length of side of square hole 4 is not less than the maximum length in the E utmost point pole cross section of three core sockets.
Claims (1)
1. two core attaching plugs, include a housing (1), are provided with pair of conductive jack (2) on the end face of housing, are respectively arranged with two grafting conductors that are connected with two lead-in wires in rear end (3) in conductive jack; It is characterized in that: on described housing (1) end face, also having a cross section is foursquare square hole (4), and the position of square hole is corresponding with the E utmost point pole of three core sockets, and the cross section length of side of square hole (4) is not less than the maximum length in the E utmost point pole cross section of three core sockets.
