[embodiment]
The ginseng Figure 1 and Figure 2, the utility model electric connector is installed on the circuit board 4, it comprises insulating body 1, somely is contained in the conducting terminal 2 of insulating body 1 and is assembled on the insulating body 1 and plugs a pair of fixture 3 that is positioned on the circuit board 4, is from top to bottom direction in this definition electric connector to the direction of circuit board 4.
Ginseng Fig. 2,3, the roughly rectangular structure of insulating body 1, it comprises the base portion 10 adjacent with circuit board 4 and from base portion 10 upwardly extending hyoplastrons 11, four limits of base portion 10 extend to form header board 12 and back plate 13 and a pair of side plate 14 that is connected forward and backward plate 12,13 that be arranged in parallel with described hyoplastron 11 straight up, and this forward and backward plate 12,13 and side plate 14 enclose the host cavity 15 that forms an encirclement hyoplastron.Base portion 10 and circuit board 4 relative one sides are installed surface 101, hyoplastron 11 is provided with some terminal containing slots 16 that run through base portion 10 downwards, described conducting terminal 2 is contained in these terminal containing slots 16 and extends installed surface 101 downwards, is inserted in then in the jack 41 corresponding set on the circuit board 4.Base portion 10 two ends are protruding with the brace table 102 that is installed on circuit board downwards, and the front and back width of this two brace table 102 is unequal.Be equipped with an elongated slot 103 parallel with described side plate 14 on each brace table 102, this groove 103 is provided with the accepting groove 17 a pair of spaced apart from each other that upwards runs through base portion 10.In conjunction with shown in Figure 5, each accepting groove 17 includes near the outer wall 171 of insulating body 1 outer rim and the inwall 172 relative with outer wall 171, described outer wall 171 is provided with the boss 173 that protrudes to inwall 172 at accepting groove 17 tops, defining these boss 173 end faces to the distance of inwall 172 at this is groove width t, and outer wall 171 to the distance of inwall 172 is groove width T.
Ginseng Fig. 4, fixture 3 is Metal Flake structure, a pair of fixing arm 32 and a pair of plate holding part 33 that long and narrow main part 31 in the middle of it comprises and autonomous body 31 middle parts make progress respectively, extend to form downwards.In conjunction with Fig. 5 and Fig. 6, fixture 3 inserts in the accepting groove 17 through described groove 103 from bottom to top, main part 31 is arranged in the groove 103, a pair of fixing arm 32 corresponding inserted are positioned in two accepting grooves 17, each fixing arm 32 and described inwall 172 relative sides are provided with some hangnails 34, the relative side of fixing arm 32 and described outer wall 171 from the top to the direction diagonally extending of described boss 173, then the direction to inwall 172 is bent to form an elasticity holding section 321 with curved portions 3211, this curved portions 3211 and boss 173 end face Elastic Contact.The Breadth Maximum of fixing arm 32 greater than groove width t, is arm wide d in the outermost end of this definition curved portions 3211 and the horizontal range of described hangnail 34 outermost end less than groove width T
Ginseng Fig. 3, the plate holding part 33 of fixture 3 extend installed surface 101 downwards and are plugged in the set location hole 42 of circuit board 4 correspondences.Two location holes 42 are non-being symmetrical set on circuit board 4, for guaranteeing that two plate holding parts 33 can accurately insert in the positioning hole corresponding 42, two pairs of accepting grooves 17 of accommodating two fixtures 3 are separated with certain distance mutually on fore-and-aft direction, wherein, the pairing brace table of a pair of accepting groove that is provided with by the back extends back the certain width of another brace table.
During assembling, earlier conducting terminal 3 is installed on insulating body 1, secondly fixture 3 is assembled in insulating body 1, the electric connector that assembling is finished is mounted on the circuit board 4 at last.During assembling fixture 3, ginseng Fig. 5 and shown in Figure 6, fixing arm 32 inserts accepting groove 17 from bottom to top, fixing arm 32 is in the process that is not inserted to boss 173, though hangnail 34 is in contact with one another with inwall 172, but amount of interference between the two very little (about 5 μ m), the interfering edge that this amount of interference produced can be ignored, in addition, because the wide d of arm is less than groove width T, therefore have the gap between the outer wall 171 of fixing arm 32 and accepting groove 17, whole fixing arm 32 does not almost have the effect of interfering edge at boss 173 lower zones and accepting groove 17, can guarantee that so the accepting groove 17 of boss 173 belows can not be subjected to the wearing and tearing of metal fixing 3.After fixing arm 32 upwards is inserted into boss 173, because groove width t is less than the wide d of arm, elasticity holding section 321 will be subjected to the lateral compression of boss 173 and make fixing arm 32 be forced to inwall 172 flexural deformations, also make simultaneously the interfering edge enhancing of 172 of hangnail 34 and inwalls.Because the radian of curved portions 3211 is bigger on the elasticity holding section 321, this curved portions 3211 can not thrust in the boss 173, is the relation of Elastic Contact between the two.Move along with on the continuing of fixing arm 32, be resisted against in the process of boss 173 end faces until curved portions 3211 outermost end, the lateral compression power that elasticity holding section 321 is subjected to boss 173 strengthens gradually, fixing arm 32 also increases to the bending deformation quantity of inwall 172 thereupon, thereby force hangnail 34 progressively to thrust in the insulating body of boss 173 walls, be inserted into accepting groove 17 fully until fixing arm 32.So, fixture 3 just firmly combines with insulating body 1 by the dual fixing effect of the resilient abutment between the interference engagement between hangnail 34 and the accepting groove 17 and boss 173 and the accepting groove 17.
The groove width T of accepting groove 17 is greater than the wide d of the arm of fixing arm 32 in the utility model electric connector, thereby guarantees that hangnail 34 can not thrust 172 li of the inwalls of the accepting groove 17 of boss 173 belows, guarantees the integrality of accepting groove 17 to the full extent; In addition, because groove width t is less than the wide d of arm, so, make not only that hangnail 34 is stressed to be thrust 172 li of the inwalls of accepting groove 17 and realize the fixing of 1 of fixture 3 and insulating body, and be subjected to the lateral compression of boss 173 that the retain strength of 1 of fixture 3 and insulating body is further promoted, thereby guarantee fixture 12 stable being immobilizated in the insulating body 1 by elasticity holding section 321.
