The utility model has the beneficial effects that (1) the utility model is that Combined fireproof is spent electric connector and is commonly electrically connected It connects device and Combined fireproof flower electric connector is individually directly either carried out integrated injection forming, Combined fireproof flower electrical connection Device is wrapped by insulated plastic, thus prevented electric connector in sparkproof female and sparkproof male plug it Between, the touching of electric connector in single type sparkproof female, single type sparkproof male plug electric leakage or short circuit occur together The phenomenon that, so as to avoid the generation of safety accident.(2) notification number is sparkproof electric connector disclosed in CN109301612A It is equivalent to knockdown electric connector, size is almost similar with general electric connector, and the utility model is namely based on this Any has devised Spark-proof plug that is a kind of relatively simple for structure and being convenient for injection molding, sparkproof female and common female plug Head, sparkproof male plug and common male plug, single type sparkproof female and the common female of single type, single type sparkproof The size of male plug and the common male plug of single type be it is the same, can thus accomplish injection molding Spark-proof plug and Both productions can be molded by not needing more mold exchange when ordinary plug, single type Spark-proof plug and single type ordinary plug Product, to improve the efficiency of production.(3) insulating body of the utility model is divided into first female main body, second female main body or the One princess's body, second princess's body, that is to say, that each electric connector is individually to have carried out integrated injection forming in the first master It is fixed after being attached in body or the second main body, between them simply by the first connecting bridge, the second connecting bridge, third connecting bridge Together, thus first female main body, second female main body, first princess's body, second princess's body be equivalent to single type female or Single type male plug.The advantages of designing in this way is exactly external the electric connector for welding positive circumscripted power line and welding cathode The electric connector of power supply line is isolated after being equivalent to individually progress injection molding separately, to avoid positive electric connector and negative electricity There is a phenomenon where electric leakage or short circuits together for connector touching.(4) rear cover of the utility model is divided into the first nut cap, the second lid Cap, the first nut cap snap onto the rear end of the first main body, and the second nut cap snaps onto the rear end of the second main body, and the first nut cap and second Nut cap is fixed together after being attached by front end connecting bridge, middle part connecting bridge, rear end connecting bridge, the purpose designed in this way It is separated also for the first nut cap and the second nut cap, to realize the electric connector and handle for welding positive circumscripted power line The electric connector of welding cathode circumscripted power line, which is thoroughly isolated, to be separated, along with the first sealing ring is screwed into respectively by its internal screw thread Latter snaps onto the rear end of the first main body and the second main body in the inner wall external screw thread of the first nut cap and the second nut cap of rear cover；When When influence of the plug face to rugged environments such as the erosion of medical fluid, the infiltrations of moisture, it is main that medical fluid and moisture etc. may not flow into first The inside of body and the second main body, but along the sky formed between the first main body and the second main body, the first nut cap and the second nut cap Chamber is fallen on ground, avoid positive electric connector and cathode electric connector to touch to greatest extent in this way together with occur electric leakage or The phenomenon of short circuit.(5) side of the rear cover of the utility model is connected with the first dustproof cover and the second dustproof cover, and the first dustproof cover can To be inserted into sparkproof male plug or common male plug, the second dustproof cover is inserted into sparkproof female or common female plug Head, and the second dustproof cover is inserted into the first dustproof cover；The side of single type rear cover is connected with the big dustproof cover of single type With the small dustproof cover of single type, the big dustproof cover of single type is inserted into single type sparkproof male plug or the common male plug of single type In head, the small dustproof cover of single type is inserted into single type sparkproof female or the common female of single type, and single The small dustproof cover of formula is inserted into again in the big dustproof cover of single type.The purpose designed in this way mainly has both sides to consider, and first Aspect is unmanned plane when not carrying out flight, and dustproof cover can play dustproof effect to the electric connector in plug；The Two aspects are unmanned planes under the influence of flying surface is to rugged environments such as the erosion of medical fluid, the infiltrations of moisture in the sky, sparkproof Female is inserted into common male plug, common female is inserted into sparkproof male plug, the insertion of single type sparkproof female In to the common male plug of single type, when the common female of single type is inserted into single type sparkproof male plug in the work of sealing ring Play the role of waterproof under, and since the second dustproof cover is inserted into the first dustproof cover or the small dustproof cover insertion of single type Having arrived in the big dustproof cover of single type to play prevents medical fluid and moisture etc. to be flowed into dustproof cover, to avoid stopping in unmanned plane When work, when the first dustproof cover is inserted into sparkproof male plug or common male plug, the second dustproof cover be inserted into sparkproof When female or common female, the big dustproof cover of single type be inserted into single type sparkproof male plug or the common male plug of single type When, single type small dustproof cover is when being inserted into single type sparkproof female or the common female of single type, medical fluid and moisture will not It is flowed into the electric connector in plug either single type plug, has prevented the generation of safety accident.
