Abstract

The utility model relates to a terminator structure for a coaxial linker to insert terminators into both sides of an insulated body by erectly inserting an on-off terminator component. The terminators can be fixed and positioned in the occupancy groove of the insulated body. The on-off terminator component uses the proximal of a vertical mainboard as an insert-firmware, and an interference part and a slant part are respectively arranged at the two sides of the mainboard so as to increase the fixedness of the terminator. Impelled by the insertion of a socket, the stretchy touch spot of a movable terminator and the semi-protruding touch spot of a fixed terminator meet and form an on-off device with a disconnection. As simple technological design, the utility model has the efficacies that the assembly is easy and the manufacturing costcan be saved.

Embodiment

Please refer to shown in Figure 1ly, be a specific embodiment of the utility model coaxial connector terminal structure, the parts of this coaxial connector 6 include: metal shell 1, insulating body 2, fixed terminal 3, movable terminal 4, base 5.This metal shell 1 of Fig. 4, Fig. 5 is coated on the periphery of insulating body 2, metal shell 1 is provided with buckle 11, and form some cramps 13 at the extension of side, when these buckles 11 combine with insulating body 2 at metal shell 1, can fasten the formed holding of fin 51 portion 55 on the base 5, these cramps 13 then are grasped in by the perpendicular mode of inserting and are inserted with on the lower concave part 29 of fixed terminal 3, movable terminal 4 insulating bodies 2, whole therefrom fixing moulding, prevent that metal shell 1 both sides grasp shakiness and resilience in the processing procedure of back, and be convenient to assembling.

Please refer to shown in Fig. 1 and 3, described insulating body 2 is divided into the cylindrical portion 22 of top and the pedestal portion of below, cylindrical portion 22 has the hollow cavity that runs through inside, as the jack 21 that cooperates connection-peg to insert, pedestal portion is seen as a middle recess that forms from looking up angle, the stage of two lateral processes, middle recess region is provided with a recessed ledge frame 212 vertical with recess, this recessed ledge frame 212 extends to the stage district of both sides, system is as the disposal area of switch terminal, the stage two bottom sides of insulating body 2 has accepting groove 25 straight down respectively, 26, accepting

groove

25,26 1 sides are respectively equipped with a

positioning port groove

27,28 draw end parts 35 as location fixing terminal, 44, also have chamfering 210 lower concave parts 29 that grasp for corresponding cramp 13 at the two ends of stage.
