The terminal 2 have in U-shaped include interior plate portion 211, outer panel portion 212 and connection interior plate portion 211 and
The U-shaped portion 21 of the interconnecting piece 213 in outer panel portion 212 and from the bottom end in interior plate portion 211 in the lateral direction on outside extend
Weld part 22.The lower end in the outer panel portion 212 is formed with pair being used for docking connector that inside pressing and bending is formed
The locking part 2121 that connecting terminal (not shown) mutually connects.
The terminal 2 arranges on the left and right directions of electric connector 100 in symmetrical two, and along the insulating body 1
It is buried in the state of front-rear direction arrangement and is held in the insulating body 1.The U-shaped portion 21 passes through integrated with insulating body 1
It forms and is held in the side wall 121.The interior plate portion 211 is immobilizated in 121 inside of side wall and reveals towards reception space 13
Out.The outer panel portion 212 is immobilizated in 121 outside of side wall and is exposed to 121 outer surface of side wall and enables the locking part
2121 are revealed in the outside of the side wall 121.The interconnecting piece 213 is immobilizated in 121 top of side wall and is exposed to the side wall 121
Dome top surface.The weld part 22 extends along bottom wall 11 towards left and right directions to 1 outside of insulating body is linearly.This Shen
Please in each terminal 2 outer panel portion 212 and weld part 22 between there is certain distance in the height direction and be formed with it is certain between
Every when terminal 2 to be molded on insulating body 1, the interval between outer panel portion 212 and weld part 22 is by insulating materials
Filling, can prevent when electric connector 100 to be soldered on a circuit board (not shown) with this, the tin being welded on weld part 22
Cream, which climbs tin, influences electric conductivity to outer panel portion 212.
Also referring to shown in Fig. 5 and Fig. 7, the metal reinforcement 3 includes main board portion 31, from before and after the main board portion 31
Outer on direction be sloped downwardly the body part 32 extended to form, extends shape from the two sides downward bending of body part 32 and inwardly
At a pair of of pars convoluta 33, extend internally from the end of the pars convoluta 33 after outside in the lateral direction bend the leg extended to form
34 and the left and right directions from the main board portion 31 the latch portion 35 that is downwardly extending of both side edges.The latch portion 35 is equipped with shape
The convex closure 351 that the outside projection in the surface Cheng Yuqi is formed, the recess portion which is used to be arranged with docking connector mutually engage with
Realize the firm fixing (not shown) of electric connector 100 and docking connector.
The metal reinforcement 3 is each provided with one at the both ends of insulating body 1.It is specific: the master of metal reinforcement 3
Plate portion 31 is covered on the upper surface of the end wall 122 of the insulating body 1, the body part 32 be revealed in the end wall 122
Outer surface on front-rear direction, the pair of pars convoluta 33 are embedded in the insulating body 1, and the leg 34 is exposed to described
The bottom wall 11 of insulating body 1 simultaneously extends the insulating body 1 in the lateral direction.The latch portion 35 is exposed to the end wall
122 side positioned at the left and right sides.
The lateral margin of latch portion 35 from the left and right sides of main board portion 31 in the application, which is bent downward, to be extended to form, in the application
Leg 34 from the outer rim of main board portion 31 in the longitudinal direction bend downward after again inwardly bending extend to form, add by metal
After strong part 3 is immobilizated on insulating body 1, apart there is a Duan Yuewei in the up-down direction between the latch portion 35 and leg 34
The region L of 0.05-0.10mm, during plastic material profiled insulation ontology 1, part plastic material is packed into the exclusion region
In the L of domain, it can also be not provided with plastic material certainly and be packed into exclusion region L, only need to meet latch portion 35 and leg 34 apart has
A distance, to prevent the tin cream when electric connector 100 to be soldered on a circuit board (not shown) on leg 34 from connecting
It is connected in latch portion 35, certainly, this section of region L is not limited with 0.05-0.10mm.In addition, body part 32 is from 31 front and back of main board portion
The upward outer two sides for being sloped downwardly extension and being revealed in 122 outer surface of end wall and pars convoluta 33 from body part 32 are downward
Bending and inwardly extension are embedded in insulating body, can be further strengthened metal reinforcement 3 and are immobilizated in 1 both ends of insulating body
Fixing effect.
To enable metal reinforcement 3 to be immobilizated in the both ends of insulating body 1, also for preventing and docking connector
The stability between metal reinforcement 3 and insulating body 1 is impacted after carrying out repeatedly docking plug.Lock in the application
The two sides in the front-back direction in portion 35 are extended with a pair of of holding part 36, and for the holding part 36 after thinning processing, thickness is less than lock
The thickness of buckle 35, then by holding part 36 to 13 inner bending of reception space of electric connector 100 be arranged to form inner buckle structure,
During being molded insulating body 1, plastic material can wrap the holding part 36 of the infolding so that the holding part 36 is curved
Folding is embedded in the insulating body 1.Certainly may also occur following two embodiment in other embodiments, the first
(please referring to shown in Fig. 8): holding part 36 ' is arranged after thinning processing without bending, which prolongs in the longitudinal direction
It stretches and is embedded in insulating body 1, there is good fixing effect；Second (not shown): holding part do not thin processing and
With the latch portion 35 thickness having the same, but still it is carried out to handle to 13 inner bending of reception space and with this not thin
The holding part of setting can also bend and be embedded in insulating body 1.
The foregoing is merely some embodiments of the utility model, the embodiment being not all of, the common skill in this field
Art personnel are by reading any equivalent variation taken technical solutions of the utility model of the utility model specification
The claim of the utility model is covered.
