Embodiment

Below existing cited in conjunction with the accompanying drawings embodiment, to electric connector structure of the present utility model, feature and effect describe in detail as after.

See also shown in Figure 1ly, be the specific embodiment of the utility model electric connector structure, this electric connector 100 is by base 1, some conducting terminals 2, supports shell fragment 3 and protective covers 4 are constituted; This base 1 is a cuboid form, the wide slightly agent structure 11 of narrow slightly two ends in the middle of having one, extend interlaced row in opposite directions at the narrow slightly part front/rear end of main body 11 and offer the fixedly terminal groove 12 of plurality of conductive terminals 2, these terminal grooves 12 are to be made of jointly a sipes 121 and a slit 122, each has the accepting groove 13 with terminal groove 12 a fixed support shell fragment 3 in the same way in terminal groove 12 2 sides, and accepting groove 13 has close planform with terminal groove 12; Be provided with guide sleeves 14 in wide of main body 11 2 ends, be provided with on these guide sleeves 14 with so that to the deep hole 141 of socket, connector positioning and fixing, described guide sleeves 14 has location, fixes, the many efficacy effects of fool proof; Be provided with edge-on projection 16 in the middle part of 11 wide side arm faces 15 of main body, these edge-on projection 16 upper end band arcuate structures, be interrupted certain distance in edge-on projection 16 2 sides and installed a formula projection 17, be provided with button portion 171 in each formula projection 17 top to outer rim, to provide and protective cover 4 buckle mutually.

The semicircular arc portion 22 that plurality of conductive terminals 2 has fixed part 21, the bending that is connected with fixed part 21 forms and along semicircular arc portion 22 oblique extended elastic contact parts 23 has weld part 24 at fixed part 21 tail ends in addition.

Support shell fragment 3 has equivalent structure basically with conducting terminal 2, and because of the two role difference, it is bigger to support shell fragment 3 support picking-up protective covers 4 required strength, so the elastic contact part cross section width of support shell fragment 3 is greater than conducting terminal 2; Another difference is to be the consideration in response to elastic strength, and the oblique arm length of elastic contact part is different with conducting terminal 2.

Protective cover 4 is covered on base 1, concrete structure sees also shown in Fig. 1,2, this protective cover 4 is provided with a substrate 41, in this substrate 41 be provided with run through up and down and with the corresponding and vertical perforation 42 of base 1

terminal groove

12,42 vertical up and down corresponding because of boring a hole with the terminal groove 12 of base 1, if when assembling conducting terminal 2 deflections take place, perforation 42 can be spacing to the tram with conducting terminal 2, avoids the terminal deflection and influence the connector result of use; A pair of location hole 43 is arranged at the guide sleeves 14 corresponding positions with base 1, side end edge near location hole 43 is provided with the through hole 44 of walking for 1 formula projection 17 of base, protective cover 4 substrates 41 two side faces are extended with side arm 45, described side arm 45 is that the skewback 47 by middle square 46 and middle square 46 2 sides constitutes, each skewback 47 inner arm face has the grab 471 of buckle mutually with base button portion 171, square 46 is provided with for edge-on square 16 and puts the fluting 461 of appearance in the middle of being communicated with between through hole 44 in addition, and grab 471 is to combine with base 1 is more close in order to reach protective cover 4 with the structural design of fluting 461.

Now please join shown in the diagrammatic sketch 3, with plurality of conductive terminals 2 and support shell fragment 3 and be individually fixed among base 1 terminal groove 12 and the accepting groove 13, the fixed part 21 of conducting terminal 2 is fixed in the sipes 121 of terminal groove 12, fixed part 21 upper ends are contained among the slit 122, protective cover 4 from base 1 top aimed at and be inserted in thereafter, location hole 43 is cooperated with guide sleeves 14 reach the location, protective cover 4 is under guide sleeves 14 effects, about and fore-and-aft direction be restricted and can't rock, and under fluting 461 effect, produce contrapositions with the edge-on square 16 of base 1, form the effect of location; At this moment, support shell fragment 3 protective cover 4 is supported picking-up, make protective cover 4 and base 1 keep certain distance, make conducting terminal elastic contact part 23 not exceed protective cover 4 end faces, structure as shown in Figure 4; Because of the effect of supporting shell fragment 3 makes protective cover 4 be in quick condition, hold down by the grab 471 and the button of the button portion 171 of base 1, define protective cover 4 the moving of vertical direction, make protective cover 4 and base 1 connect into an assembly, its structure sees also shown in Figure 5.

Electric connector 100 is comparatively simple with butt connector 200 connected modes, shown in Fig. 6,7, the deep hole 141 that butt connector 200 reference columns 60 are inserted electric connector 100 guide sleeves 14 gets final product, protective cover 4 disturbs downward slippage in external force, the elastic contact part 23 of plurality of conductive terminals 2 is exposed with butt connector 200 conducting terminals 50 to contact, to realize the signal transmission between two circuit boards, as shown in Figure 8.Taking two connectors apart only needs to extract with slight strength; support shell fragment 3 bounces are upspring protective cover 4 after losing external force; this moment; protective cover 4 grabs 471 fasteners are in button portion 171; protective cover 4 can only slide in allowed band; protective cover 4 end faces of upspringing surpass conducting terminal 2 elastic contact parts 23, and the conducting terminal protective effect is provided.

The utility model institute for embodiment and accompanying drawing, it just is made for the structure of explanation the utility model, the utility model structure is not limited, the utility model still can have other variation execution mode, everyly be familiar with purpose and the effect that this operator can understand the utility model strictly according to the facts, carry out other pattern under this case spirit and implement not breaking away from, the equivalence that all should be considered as this case claim is implemented.
