Embodiment

See also Figure 1 and Figure 2, the improvement of bayonet connector of the present utility model comprises:

Insulating body 1, its front end face is provided with a spliced eye 11, the front and rear end is provided with plural terminals hole 12, this plural terminals hole 12 is connected with this spliced eye 11, wherein, this spliced eye 11 further is provided with a node 13 near middle position, these insulating body 1 both sides further are provided with a groove 14, and the end face two ends further are provided with a trip 15;

The first terminal group 2, be made up of plural terminals, this terminal has base portion 21, contact site 22 and weld part 23, wherein, this contact site 22 is bent downwards and is extended forward by below, base portion 21 rear ends and forms, and this weld part 23 is extended upward and be bent into backward the surface stuck pin by base portion 21;

Second terminal group 3, arrange terminal 32 by front-seat terminal 31 and back that plural terminals is formed, this terminal has base portion 311,321, contact site 312,322 and weld part 313,323, wherein, this contact site 312,322 is extended back and is bent forward by below, base portion 311,321 rear ends and forms, upwards bend after the weld part 313 of this front row terminal 31 is extended forward by base portion 311 and form, the weld part 323 of this back row's terminal 32, directly extended upward by base portion 321 and to form, the weld part 313,323 of described forward and backward row's
