Embodiment
Embodiment 1:
Consult Fig. 1.The utility model high temperature high voltage resistant multicore insulated enclosure plug connecting line mainly is made up of seven core plugs, injecting glue die sleeve 4, seven core fluoroplastics line groups 5, rubber outer 6 and O RunddichtringO 7.
Consult Fig. 2.Seven core plugs are by contact pin 1, and insulating case 2 and shell 3 are formed, at seven contact pins 1 of insulating case 2 parcels.1.5 millimeters of the diameters of contact pin 1,45 millimeters of length.Six roots of sensation contact pin 1 circle distribution in seven contact pins 1 evenly distributes, and another root contact pin 1 is in the center.Insulating case 2 ends are exposed at the identical and two ends seven contact pins 1 of the length of seven contact pins 1 respectively, and the length that seven contact pins 1 expose insulating case 2 ends is 10 millimeters.At outer 3, seven contact pins 1 of shell that are with of insulating case 2 outer walls, insulating case 2 and shell 3 adopt the HTHP injection-compression molding.The bipassage ring connected in star is arranged on the cylindrical of shell 3, an O RunddichtringO 7 is arranged in each groove.
Consult Fig. 1.Two ends in seven core fluoroplastics line groups 5 connect one seven core plug respectively, in seven core fluoroplastics line groups 5 and seven core plug junctions an injecting glue die sleeve 4 are arranged; Injecting glue die sleeve 4 is seven lead mutually insulateds of seven core fluoroplastics line groups 5 and parcel, seven contact pins 1 of seven core plugs respectively with seven core fluoroplastics line groups 5 in a wire bonds.
