Abstract
The invention discloses a plug with concave inner sides. The plug with the concave inner sides structurally comprises a plug seat and plug rods, wherein the two plug rods are symmetrical and of a metal block-shaped structure, the inner side of each plug rod is concave and arc, and the front end of each plug rod is conical. The plug with the concave inner sides have the advantages that the concave structures of the inner sides of the plug rods can be bitten by arc metal pieces in the plug seat, the biting stability between the metal pieces and the plug rods is increased, the contact area of metal conductors between the metal pieces and the plug rods is increased, and the bearable maximum current intensity is increased.
Description
Technical field
The present invention relates to a kind of plug, relate in particular to a kind of inner side female plug that is difficult for becoming flexible and increasing load in socket that is inserted into.
Background technology
As shown in Fig. 1 and Fig. 3 in Figure of description: the front view that Fig. 1 is traditional plug, its inserted link 12 is direct rod shape; Fig. 3 is that the traditional plug shown in Fig. 1 is inserted into the structural representation in socket 3.The occlusion structure schematic diagram of the sheet metal 31 in inserted link 12 and the socket 3 of the traditional plug from Fig. 3 can find out that the shortcoming of traditional plug is: 1, and after sheet metal 31 elasticity weaken, the inserted link 12 of traditional plug just cannot cause with sheet metal 31 close contacts loosening and can not conduct electricity; 2, the inserted link 12 of traditional plug and contacting of sheet metal 31 are dotted line contact, and the shortcoming of the mode of this contact is large thereby the circulation that can not bearing great current of contact area small resistor.
Summary of the invention
Problem to be solved by this invention is to provide a kind of inner side female plug, and it is simple in structure, and cost is low, easy to use, is inserted into the use that is difficult for becoming flexible and meeting high-power electric appliance in socket.
In order to solve above technical problem, technical scheme of the present invention is as follows:
A kind of inner side female plug, its structure comprises connector assembly and plug bar.Described plug bar is provided with symmetrical two, and described plug bar is the block structure of metal, and the inner side of described plug bar is the arc shape of spill; The front-end-cone shape of described plug bar.
The invention has the beneficial effects as follows: the concave structure of plug bar inner side can be by the sheet metal interlock of the curved shape in socket, thereby has increased the stability of the interlock between sheet metal and plug bar and can increase the contact area of the metallic conductor between sheet metal and plug bar and increase the maximum current intensity that can carry simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of traditional plug.
Fig. 2 is the structural representation of the embodiment of the present invention.
Fig. 3 is the interlock schematic diagram of the sheet metal in inserted link and socket after traditional plug is inserted in socket.
Fig. 4 is the interlock schematic diagram that the embodiment of the present invention is inserted into the sheet metal in plug bar and socket in socket.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 2 and Figure 4, its structure of the present invention comprises connector assembly 21 and plug bar 22.Plug bar 22 is provided with symmetrical two, and plug bar 22 is the block structure of metal, and the inner side of plug bar 22 is the arc shape of spill; The front-end-cone shape of plug bar 22.
As shown in Figure 3 and Figure 4, the concave shape arcuate structure of the inner side of plug bar 22 can with socket 3 in arc shape sheet metal 31 be cambered surface interlock, this cambered surface interlock can increase the stability of the interlock between sheet metal 31 and the plug bar 22 in connector assembly 3, and cambered surface interlock simultaneously increases the contact area between plug bar 22 and sheet metal 31 and increased the maximum current intensity that can carry between plug bar 22 and sheet metal 31.
As shown in Figures 2 and 3, the tapered shape of plug bar 22 front end, this shape can make plug bar 22 successfully be inserted in socket 3.
Claims (2)
