Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

See also Fig. 1 and Fig. 2, this two width of cloth figure is the exploded view and assembling schematic diagram of connector improvement structure of the present utility model, connector improvement structure 1 of the present utility model is by conducting terminal 6, insulation framework 2, elastic parts 5, slide block 3, a pull bar 4 and a metal baffle 7 are formed, being provided with terminal groove 22 in the insulation framework 2 is arranged on wherein for conducting terminal 6, one side of insulation framework 2 is provided with a slide block 3, one pull bar 4 and an elastic parts 5, the periphery is provided with trip 24 and fastens with metal baffle 7, wherein elastic parts 5 is fixed on the elastic parts seat 21, the other end is being replaced slide block 3, when memory card 8 inserts, the elastic force that this elastic parts 5 provides card to withdraw from; Slide block 3 is provided with guide channel 32 and makes pull bar 4 follow guide channel 32 to slide, and slide block 3 is established a trip 31, in order to the groove of buckle memory card 8; Pull bar 4 one ends are fixed on the pull bar fixing hole 23 of insulation framework 2, and the other end is in guide channel 32, when slide block 3 pushes with memory card 8 and when sliding, pull bar follows guide channel 32 and slides, and support slipper 3 is in the fixed position; Metal baffle 7 covers on the insulation framework 2, establish an elastic pressuring plate A71 corresponding to pull bar 4 tops, be unlikely to leave guide channel 32 with compacting pull bar 4, and establish elastic pressuring plate B72 in the middle of the metal baffle 7 in order to compacting memory card 8, side is established a conducting strip 73, in order to contact the conducting checking circuit with switch terminal 61, and button hole 74 is established in the position of the trip 24 of corresponding insulation framework 2, utilize trip 24 and button hole 74 that insulation framework 2 is fastened with metal baffle 7, and form a connector structure-improved 1.
