Utility model content
The purpose of this utility model is to provide a kind of stay preventing type electric connector, the generation of adverse consequences when it can avoid off-gauge plug to misplug.
Another object of the present utility model is to provide a kind of stay preventing type electric connector, strengthens the holding capacity of its fool proof shell fragment.
The purpose of this utility model is achieved through the following technical solutions.
A kind of stay preventing type electric connector, comprises plastic body, is installed in the terminal group of plastic body inside and is sheathed on the shell of plastic body outside, in described plastic body, be also provided with shell fragment jack, shell fragment jack interpolation is provided with fool proof shell fragment;
Described fool proof shell fragment is one to have flexible bending lamellar body, comprises junction and Access Division; The free end of described junction is provided with sliding portion and the stop part that left and right is set up in parallel; The inner side of junction is also provided with stressed supporting construction, in the time that junction is stressed and the end face of Access Division/plastic body inconsistent using as bearing fulcrum.
Wherein, the both sides on described plastic body be respectively equipped with one described in shell fragment jack, in each shell fragment jack, be all inserted with a fool proof shell fragment, and the free end that is installed in two fool proof shell fragments of shell fragment jack is symmetrical structure.
Wherein, described fool proof shell fragment is one to have flexible lamellar body by junction and Access Division one brake forming.
Wherein, described Access Division is provided with a draw-in groove, in order to this electric connector is fixed in the shell fragment jack of described plastic body.
Wherein, described sliding portion is a lamellar body forming to Access Division direction bending extension.
Wherein, the two edges of the inner side of junction are respectively equipped with a stressed supporting construction.
Wherein, described stressed supporting construction is specially a bending structure.
The utility model compared with prior art, beneficial effect is: the stay preventing type electric connector that the utility model provides, by be provided with stop part and cunning portion in one end of fool proof shell fragment, in the time that off-gauge and size are inserted body compared with small plug, this plug can fasten mutually with stop part, makes by this this plug to enter in body, and the plug conforming to when specification is while inserting body, this plug can promote cunning portion towards the top of body, make by this this plug can be inserted in body; Meanwhile, after this plug is extracted, the elasticity of fool proof shell fragment itself can make it return back to its initial position, therefore need be by external force, and can make fool proof shell fragment get back to its initial position.In addition, fool proof shell fragment is also provided with stressed supporting construction, this stressed supporting construction in the time that shell fragment is stressed and the inconsistent formation of the end face of plastic body bear fulcrum, can greatly increase the holding capacity of this fool proof shell fragment, anti-mis-insertion power can reach 9kgf min.
