[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model bayonet connector is described further.

Please be simultaneously referring to figs. 1 through shown in Figure 4, the utility model bayonet connector is used to accept memory module (not icon) and comprises the insulating body 1 that is longitudinal, offers central slot 10 along its longitudinally; Plurality of conductive terminals 2 is located at the both sides of central slot 10, with machinery and electric connection memory module; Pair of catches device 3, it is terminal relatively to be located at 1 liang of insulating body, and each locker 3 includes working of plastics 30 and metalwork 31 two parts.

This working of plastics 3O extends and forms from insulation body 1 two ends, and its front end further extension is provided with fastening arm 32, this working of plastics 30 fastens terminal inboard also being provided with to projecting inward holding parts 33 with the fixing memory module of arm 32, these working of plastics 30 outsides also are provided with groove 36, to match with metalwork, this metalwork 31 is positioned at the outside that fastens arm 32.

Described metalwork 31 is formed by the first arm 341 and by second arm 342 that the first arm 341 is bent to form, second arm 342 is positioned at the first arm 341 outsides, and which is provided with and can limit the stop sections 35 that the first arm 341 excessively moves, described two metalworks are and are oppositely arranged, and shape is identical.Wherein, the holding section 40 that the end of the first arm 341 extends upward and bends, described working of plastics 30 fastens arm 32 ends and is provided with the support slot 401 that holds mutually with described holding section 40, described the first arm 341 is fitted to be fixed in and is fastened arm 32 outsides, and move along with fastening moving of arm 32, described second arm 342 is formed by the first arm 341 doublings extension, described second arm 342 comprises the connecting portion 343 that connects stop section 35 and the first arm 341, stop section 35 is outwards to be bent to extend by connecting portion 343 to form, 35 terminal extensions downwards are provided with weld part 38 in the stop section, this weld part 38 is approximately perpendicular to stop section 35, described weld part 38 is provided with through hole 380, correspondingly, on working of plastics 30, be provided with the accommodation hole 390 of correspondence with it, one scolder (not shown) is set in the accommodation hole 390, this weld part 38 is welded mutually, with circuit board to realize the electric connection of this bayonet connector and circuit board.

Please refer to Fig. 5 to shown in Figure 7, second embodiment for the utility model bayonet connector, it is with the foregoing description difference: described second arm 342 by at least one lateral bucklings of the first arm 341 extend and form (second arm 342 described in the present embodiment by the first arm 341 both sides relative bend to extend form), described two stop sections 35 are formed by symmetrical relatively extension the in second arm, 342 both sides, such two stop sections 35 are identical, so production cost has been saved in repeatedly die sinking; Described electric connector comprises a weldment 38 in addition, it is installed on the insulating body 1, described weldment 38 comprises a main body 381 and bends the fixed block 382 that extension forms relatively by main body 381 both sides, described fixed block 382 ends are provided with the holding section 383 of bending, correspondingly, insulating body 1 is provided with the slot 11 that cooperates with it, the height of this slot 11 is greater than the height of holding section 383, and it is gapped between the main body 381 of weldment 38 and the insulating body 1, so that weldment 38 can relatively move at above-below direction with insulating body 1, make this weld part 38 weld fixing mutually by scolder again with circuit board.
