China utility model patent CN 201374430 Y have announced a kind of connector, comprise first connector body (1) and second connector body (2), this first connector body (1) is provided with inserted link (3), described second connector body (2) is provided with jack (4), is provided with barrel-shaped spring (5) in this jack (4).Advantage is, the connector that the utility model provides by barrel-shaped spring is set in jack, thereby better is fixed in the jack inserted link, makes the electrical connection of connector more stable, and cost simple in structure is low simultaneously.But the barrel-shaped spring of this utility model connector is not suitable for by big electric current, the long-term back barrel-shaped spring easy deformation of using, and its injection casing is excessive and built on the sand.
Summary of the invention
The utility model is in order to overcome the shortcoming that above prior art exists, its technical scheme that provides provided a kind of easy to assemble, patch simple little, the easy to assemble big electric current connector that can lead to big electric current of firm, volume.
For this reason, the utility model provides a kind of big electric current connector easy to assemble, it comprises female terminal, female terminal connects an end of lead, and the female terminal appearance is provided with injection casing, and an end of male terminal is embedded in injection casing inside and is electrically connected with female terminal, the end that male terminal is connected with female terminal is provided with a circle draw-in groove, injection casing is embedded with buckle, and the buckle middle part is provided with the insertable round tube hole of male terminal, and round tube hole one side is provided with the projection that can block the male terminal draw-in groove.
For further specifying of described big electric current connector easy to assemble, projection one side of buckle is provided with spring, and buckle connects the spring place and is provided with the spring inserting column.
For further specifying of described big electric current connector easy to assemble, the both sides of buckle are provided with the opening pawl, and the position of the corresponding opening pawl of injection casing is provided with groove.
For further specifying of described big electric current connector easy to assemble, buckle is provided with the hand end, and the hand end is exposed to the injection casing outside.
For further specifying of described big electric current connector easy to assemble, the lead that connector connects is metal knitted line, uses metal knitted line to make lead more soft, and the other end of metal knitted line can be made terminal, and electric conductivity is higher.
For further specifying of described big electric current connector easy to assemble, metal knitted thread end crimping becomes flat, and the middle part is provided with punching, and the female terminal crimping also is fixed in the punching, and this structure makes the electric conductivity of product better.
For further specifying of described big electric current connector easy to assemble, the injection casing injection molding is in female terminal and punching crimping place.The female terminal crimping and be fixed in the punching after, injection moulding injection casing again, assemble easier, structure is more solid, more volume is littler.
The beneficial effects of the utility model are: because the end that male terminal of the present utility model is connected with female terminal is provided with a circle draw-in groove, described injection casing is embedded with buckle, the buckle middle part is provided with the insertable round tube hole of male terminal, and round tube hole one side is provided with the projection that can block the male terminal draw-in groove.The docking apparatus that the utility model is simple in structure, easy to assemble, patch firm, overall dimension is little, be applicable to high-current circuit.
