Abstract
The two-pin changeover plug consists of conductive pins, a shell, an insulated wire, a changeover device and a lead protection head 8. The conversion device consists of a conversion wheel and a limiter. The conversion wheel 2 is installed on the conductive pins, and two ring teeth of the position limiter fixed on the shell are matched with two ring grooves opposite in position on the conversion wheel, so that the two conductive pins are limited to rotate in the ranges of parallel position and 60-degree angle position, and the two conductive pins can be inserted into a three-hole socket and a three-hole socket, thereby realizing two functions of a plug, replacing the existing two-pin plug without a ground wire, and being conveniently used for various instruments and meters and various electrical appliances.
Description
The utility model belongs to the electric elements class, belongs to the plug class particularly.
The used attaching plug of existing various instrument and meter and electric equipment all is Two-feet plug or three-pin plug, Two-feet plug can not insert Three-hole socket in use, and three-pin plug can not insert two hole socket, the two can not be general, work is extremely inconvenient, often join socket in addition, increased expense.
The purpose of this utility model is the problem at above-mentioned existence, designs a kind of two pin changeover plugs, and this plug only needs former Two-feet plug is made improvements slightly, can make it to insert two hole socket, can insert Three-hole socket again.
The purpose of this utility model realizes in the following manner; two pin changeover plugs are made up of conductive feet 1, shell 4, set screw 5, terminal screw 6, insulated conductor 7, pilot protection head 8; respectively adorn a conversioning wheel 2 on two conductive feet 1; have on the conversioning wheel 2 two positions relatively, radian is 60 ° cannelure 9; two annular tooth 10 that are fixed on the stop 3 on the shell 4 match with cannelure 9, and extend in it.
Disposable two pin changeover plugs are made up of conductive feet 1, shell 4, insulated conductor 7, pilot protection head 8; shell 4, insulated conductor 7, pilot protection head 8 are one; conversioning wheel 2 is installed on the conductive feet 1; have on the conversioning wheel 2 two positions relatively, radian is 60 ° cannelure 9; two annular tooth 10 that are fixed on the stop 3 on the shell 4 match with cannelure 9, and extend in it.
Content of the present utility model is described in detail in detail with reference to the accompanying drawings.
Fig. 1 the utility model structural representation
The horizontal cut-away view of Fig. 2 conversioning wheel
Fig. 3 cannelure, annular tooth working state schematic representation
With reference to accompanying drawing, the terminal screw 6 on the conductive feet 1 connects insulated conductor 7.Set screw 5 works to regulate the degree of tightness clearance plane fixed housing 4 of conversioning wheel 2.On two conductive feet 1, respectively adorn a conversioning wheel 2 and form the conductive feet conversion equipment with the stop 3 that is fixed on the shell 4, relative two cannelures 9 in position match with two annular tooth 10 on the stop 3 on the conversioning wheel 2, and limiting two conductive feet 1 can only rotate in parallel position and 60 ° of angle position ranges.Change conductive feet with have gentle hands, when it is horizontal, two conductive feet can be inserted in the two hole socket, gently change conductive feet again when position, 60 ° of angles, two conductive feet then can be inserted in the Three-hole socket, realized that a plug has the characteristics of two kinds of functions, can replace existing Two-feet plug, and is used for various instrument and meters and various electrical equipment.
Conversioning wheel 2 can adopt insulating material or conductor material, and stop 3 adopts insulating material.Stop 3 also can be integral with shell 4.
Disposable two pin changeover plugs, shell 4, insulated conductor 7,8 injection mouldings of pilot protection head and be molded into one, insulated conductor 7 directly is welded on the conductive feet 1, and does not need set screw 5, terminal screw 6.Conversioning wheel 2 is installed on the conductive feet 1, between conversioning wheel 2 and shell suitable space must be arranged, to make things convenient for the rotation of conductive feet 1 in horizontal level and position, 60 ° of angles.
The utility model both can insert two hole socket, can insert in the Three-hole socket again, had realized that a plug has two kinds of functions, can replace existing two pin, not be widely used for the three-pin plug of ground wire on various instrument and meters and the various electrical equipment.
