As shown in Fig. 2 the insulating body 1 has provided multiple accepting holes 11, multiple terminals 2, correspondence is immobilizated in institute
State in accepting hole 11；The one side of the accepting hole 11 is protruded out to form a stop section 111, and terminal 2 described in block is housed in described
Moved up and down in hole 11；The another side of the accepting hole 11 protrudes out to form a projection 112, the projection towards the solder 3
112 is concordant with the lower surface of the insulating body 1.
As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, the terminal 2 has a location division 21, the terminal horizontal of the location division 21
The convex portion 211 of projection one, top surface one locating surface 2111 of formation of the convex portion 211, the locating surface 2111 is located at the stop section
111 lower section, it is to avoid the terminal 2 is moved up.Torn upwards from the centre of the lower edge of location division 21 and be vertically bent to form a weldering
Socket part 22, (in certain other embodiments, the weld part 22 also can tear shape from the non-intermediate positions of the lower edge of location division 21
Into), and the location division 21 is formed a breach 27 in tear place, the projection 112 is located in the breach 27, and supports institute
State solder 3.Lower surface one solder side 221 of formation of the weld part 22, is soldered to the solder 3, and the locating surface 2111
Height between the solder side 221 and the minimum point 31 of the solder 3, make the solder side 221 sufficiently high, reduce institute
State the height of terminal 2；Further, the upper surface of the weld part 22 has a laser irradiation area 2221, and institute is irradiated by laser 6
State laser irradiation area 2221 and heat the weld part 22, the solder 3 is transferred heat to by the weld part 22, make described
The partial melting of solder 3 and be fixed on the solder side 221, it is to avoid the solder 3 all melts, and influence its subsequently with the electricity
The welding of road plate 5.
Upwardly extend to form a flat part 23 from the weld part 22, it is spacing that the side level of the flat part 23 protrudes out one
Portion, the top positioned at the stop section 111, it is to avoid the terminal 2 is moved up；The limiting section and the convex portion 211 are along level side
To the side for not contacting the accepting hole 11, the insulating body 1 can be avoided because excessively thin work as by the terminal 2 in level
Ruptured during the stress extruding in direction；Extension, which is folded upward at, from the flat part 23 forms an elastic arm 28, the elastic arm 28
A contact site 251 is connected, the chip module 4 is abutted upwards；Further, the floor projection of the elastic arm 28 and the laser
The floor projection of irradiated region 2221 is not overlapping；And the floor projection of the laser irradiation area 2221 is revealed in the accepting hole 11,
Laser 6 is set to be irradiated to the laser irradiation area 2221 by the accepting hole 11 from top to bottom.In addition, the elastic arm 28 is wrapped
Include and bend one first arm 24 that extension is formed towards away from the place perpendicular direction of flat part 23, and returned from the first arm 24
Bending extends across the second arm 25 of the place perpendicular of flat part 23, and the top of the second arm 25 forms the contact site
251 abut the chip module 4 upwards, and first arm 24 and the weld part 22 are put down vertically where being located at the flat part 23
The opposite sides in face, it is ensured that the integrally-built stability of the terminal 2.
From the top of flat part 23, extension forms a material portion 26 of company for connecting a material strip, the even material portion vertically upwards
The height on 26 tops is less than the top of the accepting hole 11；And the accepting hole 11 only covers the even material provided with a block 113
The part on the top of portion 26, reduces material strip and the width that even material portion 26 is connected, conveniently fracture material strip..
As shown in Figure 7 to 9, it is the second embodiment of the utility model electric connector 100, second embodiment is real with first
The difference for applying example is：The side of the accepting hole 11 does not protrude out towards the projection 112 of the solder 3 and supports the weldering
Material 3, the solder 3 directly supports the location division 21, it is to avoid the springing of location division 21, loses the skew of stop section 111
Go block function.In addition, the weld part 22 defines a back side 222, a through hole in the opposite one side of the solder side 221
2222, through the back side 222 and the solder side 221, the through hole 2222 is passed through from the back side 222 by the laser 6
The solder 3 is irradiated, the solder 3 is abutted a part of melted by heating of the solder side 221 and is fixed on the solder side
221, and remainder is not destroyed；Due to the setting of the through hole 2222, the laser 6 is may pass through the through hole 2222 and shine
The solder 3 is penetrated, accelerates speed of welding.Similarly, it is described logical to make laser 6 to be irradiated to from top to bottom by the accepting hole 11
Hole 2222, the floor projection of the elastic arm 28 is not overlapping with the floor projection of the through hole 2222；And the through hole 2222
Floor projection is revealed in the accepting hole 11.Remaining structure is identical with function with first embodiment, does not tire out state herein.
During the utility model electric connector 100 is assembled, the terminal 2 is first assembled to the receipts from the top down
Hold hole 11, then the solder 3 is extruded to the accepting hole 11 from bottom to up, it is abutted with the solder side 221, finally will
The laser 6 irradiates the laser irradiation area 2221 or the through hole 2222 by the accepting hole 11 from top to bottom, makes described
Solder 3 is soldered to the weld part 22.
In summary, the utility model electric connector 100 has following beneficial effect：
（1）The height of the locating surface 2111 makes between the solder side 221 and the minimum point 31 of the solder 3
The solder side 221 is sufficiently high, reduces the height of the terminal 2, meets the thin trend of electric connector 100；
（2）The limiting section and the convex portion 211 do not contact the side of the accepting hole 11 in the horizontal direction, it is to avoid institute
State insulating body 1 and be broken because crossing to be thinner than when horizontal direction is extruded by terminal 2；
(3）Laser 6 can be irradiated to the laser irradiation area 2221 by the accepting hole 11 from top to bottom, make the solder
3 abut a part of melted by heating of the solder side 221 and are fixed on the solder side 221, and remainder is not destroyed, is protected
Demonstrate,prove the flatness of solder 3, it is to avoid missing solder；
(4）The through hole 2222 runs through the weld part 22, the laser 6 is may pass through the direct irradiation of through hole 2222
The solder 3, accelerates speed of welding；
(5) projection 112 is located at the breach 27, can both position the solder 3, also can location division described in block
21, the location division 21 and the solder 3 can also be separated, prevents from climbing to the location division 21 during the welding of solder 3 melting
On, influence welding function.
Detailed description above is only the explanation of the preferred embodiment of the utility model, and non-therefore limitation the utility model is specially
Sharp scope, so, all with this creation specification and diagramatic content institute, equivalence techniques changes for it, is both contained in this creation specially
In sharp scope.
