Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described corresponding accompanying drawing.Obviously, described embodiment is only the application one
Section Example, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of the application protection.
Refer to shown in Fig. 1 to Fig. 4, the application USB socket includes some conducting terminals 10 and is shaped in described lead
Insulating body 20 on electric terminal 10.
The conducting terminal 10 include contact site 11, the holding parts 12 that are extended rearwardly to form from the contact site 11 and from
The weld part 13 that the holding parts 12 extend rearwardly to form.Some conducting terminals 10 are by being connected to the rear end of weld part 13
Material strip is combined as a whole.Defining the contact site 11 of the conducting terminal 10, to be embedded in side in the insulating body 20 be first
Side, the side that the external world is exposed to relative to contact site described in first side 11 is second side.
The insulating body 20 includes base portion 21, the docking hyoplastron 22 formed from before the base portion 21 to extension.It is described to lead
The first side of the contact site 11 of electric terminal 10 is exposed to a side surface of the docking hyoplastron 22, the end of the contact site 11
It is embedded in the docking hyoplastron 22.The first side of the base portion 21 corresponds to the opening position of holding parts 12 of the conducting terminal 10
Provided with fluting 23, the holding parts 12 that the second side of the base portion 21 corresponds to the conducting terminal 10 are provided with some locating slots 24,
The second side of docking hyoplastron 22, which is exposed, the contact site 11.The locating slot 24 with the fluting 23 in vertical direction extremely
Small part overlaps.
The locating slot 24 opens in upper end and towards docking hyoplastron 22 side, and the width of the locating slot 24 is equal to
The width of the conducting terminal 10.The injection mold keeper (not shown) positioned at the side of locating slot 24 is laid in described connect
In the second side of contact portion 11.
The USB socket injection molding forming method of the application comprises the following steps：
Conducting terminal 10 described in S101, punch forming；
S102, the conducting terminal 10 connected by material strip inserted in injection mold and fixed；
This step is to be pulled conducting terminal in the injection mold by automatic machine, and the injection mold passes through built-in
Keeper fixes the conducting terminal 10.The keeper includes the first keeper being held in the first side of holding parts 12
(not shown), in plug orientation it is attached at the second keeper in the holding parts 12 and the second side of contact site 11 (not
