Abstract

An electric connector safety choke plug capable of changing an initiating explosive device resistor comprises a connector, a printed plate jack assembly, a first printed plate, a second printed plate, a needle connector, a hole connector and the initiating explosive device resistor, wherein the front end of the printed plate jack assembled component is in abutting joint with the connector, and the tail end of the same is fixedly connected with the first printed plate; the needle connector and the hole connector are respectively fixed on the first printed plate and the second printed plate, and the initiating explosive device resistor is fixed on the second printed plate; and the first printed plate is in abutting joint with the second printed plate through the needle connector and the hole connector and connected with the second printed plate through a fastening piece so as to realize fixation and electric conduction. After the electric connector safety choke plug capable of changing the initiating explosive device resistor is connected with an electric connector, when the initiating explosive device resistor is burned down, only the second printed plate needs to be disassembled to change the initiating explosive device resistor, thereby the maintainability of the electric connector with the initiating explosive device resistor is enhanced, and the use cost of the same is reduced.

Description

technical field [0001] The invention relates to a safety plug for an electrical connector, belonging to the technical field of electromechanical components. Background technique [0002] Usually, the method of connecting the pyrotechnic resistor at the end of the electrical connector is to directly weld the resistor to the wire with the contact piece, connect a pyrotechnic resistor through the wire to the defined two holes, and finally pot the silicone rubber. Protect it with a tail cover. The disadvantage of this structure is that there is no maintainability. When the resistance of the pyrotechnic product is burned, the entire connector is also scrapped. cause considerable waste. Contents of the invention [0003] The object of the present invention is to provide a new safety plug for electrical connectors that can replace the resistance of pyrotechnics, aiming at the defect that the above-mentioned technology cannot be repaired. This structure can be conveniently plug...
