[embodiment]
For ease of better understanding the purpose of this utility model, structure, feature and effect etc., existing the utility model is described in further detail with embodiment by reference to the accompanying drawings.
As shown in Fig. 1 and Fig. 2 and Fig. 3, electric connector 100 of the present utility model is for electrically docking to realize the good transmission of telecommunication with a banjo 200, described electric connector 100 comprises: insulating body 1, one shielding casing 2 coated described insulating bodies 1 and multiple conducting terminal are contained in described insulating body 1.
As depicted in figs. 1 and 2, described banjo 200 has a docking part 3, comprise a head 31 and a main part 33 from described docking section 3, one neck 32 connects described main part 33 and described head 31, and relatively described main part 33 and described head 31 indents, its diameter is less than the diameter of described head 31 and described main part 33.
As shown in Figure 1, described insulating body 1 has an interface 11 and is positioned at the front end face of described insulating body 1, is further concaved with a host cavity 12 from described interface 11, and described host cavity 12 runs through the front and rear end of described insulating body 1 from front to back.Described insulating body 1 has top 13, two sidepieces 14 and is positioned at the relative both sides at described top 13, in the zone line of described top 13 and described two sidepieces 14 respectively indent form a first side wall 131 and 2 second sidewalls 141.Described the first side wall 131 offers a hollow hole 1311, described hollow hole 1311 is communicated with described host cavity 12, described in each, on the second sidewall 141, all there are two buckle pieces 1411, described in each, 14 of sidepieces are equipped with a stop block 142, and described in each, stop block 142 is positioned at the rear of corresponding described two buckle pieces 1411.
As shown in figures 1 and 3, described the first side wall 131 and described 2 second sidewalls 141 of described shielding casing 2 coated described insulating bodies 1, and spacing with described sidepiece 14 and described two stop blocks 142 by described top 13, avoid described shielding casing 2 to move forward and backward on described insulating body 1.One arch upward portion 211 is one-body molded with described shielding casing 2, and described in the portion 211 that arches upward be positioned at the upper shell wall 21 of described shielding casing 2, and corresponding with described hollow hole 1311.The described portion 211 that arches upward comprises a base portion 2111, one elastic contact chip 2112 extends (certainly do not get rid of and extend back) forward from described base portion 2111, described elastic contact chip 2112 has a free end 21121, described free end 21121 enters described host cavity 12 by described hollow hole 1311, contact with described main part 33, play ground connection and clamping.The described portion 211 that arches upward also comprises that a holding part is away from described free end 21121, described holding part is that a teat 2113 is formed by the inside punching press of described base portion 2111, be convexly set in described base portion 2111, described teat 2113 is positioned at the rear (according to circumstances also can be positioned at the front of described elastic contact chip 2112) of described elastic contact chip 2112, described teat 2113 also enters described host cavity 12 by described hollow hole 1311, contacts with described neck 32.The relatively described shielding casing 2 of the described portion 211 that arches upward inwardly arches upward and enters described hollow hole 1311(in the middle of other embodiment, the relatively described shielding casing 2 of the described portion 211 that arches upward outwards arches upward away from described hollow hole 1311), the elasticity of portion 211 arches upward described in can increasing, can make described elastic contact chip 2112 and described teat 2113 to the clamping of described banjo 200 with contact more stable, relatively described shielding casing 2 indents of the described portion 211 that arches upward, can also, from always reducing on the whole the volume of described electric connector 100, be conducive to the development trend of miniaturization.The described portion 211 that arches upward also comprises a breach 2114, and described breach 2114, away from described interface 11, closes on described teat 2113, and object is the elasticity that increases described teat 2113, makes described teat 2113 contact more stable with described neck 32.The elasticity that described elastic contact chip 2112 produces by its structure contacts with described banjo 200, and described teat 2113 contacts with described banjo 200 by the intrinsic elasticity of metal material.
As depicted in figs. 1 and 2, described shielding casing 2 has the two side shell walls 22 that are oppositely arranged, described in each, on side shell wall 22, be equipped with two through holes 221 corresponding with described buckle piece 1411 respectively, and be fixed with corresponding described buckle piece 1411, prevent that described shielding casing 2 is subjected to displacement on described insulating body 1.
When assembling, first multiple described conducting terminals are assembled into described insulating body 1, then described shielding casing 2 is placed on from the top down to described the first side wall 131 and described 2 second sidewalls 141 of described insulating body 1, described shielding casing 2 is limited between described top 13 and described two sidepieces 14 and described stopper section, make again described through hole 221 fasten with described buckle piece 1411, finally insert banjo 200.As Fig. 4 and Fig. 5, in the time that described banjo 200 inserts described host cavity 12, described teat 2113 is crossed the described head 31 that diameter is larger, finally falling into the described neck 32 that diameter is less contacts with described neck 32, owing to thering is obvious section of difference between described head 31 and described neck 32, so in the time that described banjo 200 insertions put in place, user can feel vibrations clearly to have good feel.Simultaneously, because the diameter of described neck 32 is less than the diameter of described main part 33, so described teat 2113 can, by described main part 33 backstops spacing, can effectively prevent that described banjo 200 from departing from described host cavity 12 under casual External Force Acting, so that affect telecommunication transmission.
In sum, the utility model electric connector has following beneficial effect:
(1) described elastic contact chip from described in the portion of arching upward extend, described in the relatively corresponding shell wall of the portion of arching upward arch upward, indirectly increased the length of the elastic arm of described elastic contact chip, make the elasticity of described elastic contact chip better, be difficult for occurring fracture damage.
(2) described elastic contact chip and the described holding part portion that arches upward described in being all positioned at is corresponding with same described hollow hole, has effectively reduced on described insulating body the number of corresponding described hollow hole with it, has guaranteed the intensity of described insulating body.
More than describing in detail is only the explanation of the preferred embodiment of the utility model utility model, non-ly therefore limit to the scope of the claims of the present utility model, so the equivalence techniques that all this creation of utilization specifications and diagramatic content are done changes, and is all contained in the scope of the claims of the present utility model.
