Description
Technical field
This application involves electric connector field, the positive anti-plug USB connector of espespecially a kind of post forming formula and its manufacturing method.
Background technique
For universal serial bus (USB) universally present in daily life, the transmission of electronic device data is most
Using this general standard；The appearance of USB3.0 standard greatly improves the transmission speed of data, in standard A Type class
In the USB interface design of type, USB3.0 can ideally realize change in design without influencing downward compatibility and constructional appearance.But
It is to guarantee that constructional appearance is constant while the field Micro USB of mobile terminal application then cannot achieve function upgrading,
3.0 standard of Micro USB finally complicates surface structure, that is, mode side by side is used to increase an interface to accommodate and increase
The function leg added, but bigger space is occupied, it is limited to the development trend of smart phone ultrathin, Micro USB3.0 is made to exist
Application on mobile phone is greatly limited, and is badly in need of the completely new high speed serialization versabus of one kind to solve the problems, such as this.
In the case, USB association is proposed completely new USB3.1 Type c-type interface connector, has combined size
With performance, the application on intelligent terminal is adapted to, but it cannot be backward compatible.It is limited to product structure complexity, exists simultaneously metal
Plate and it is located at the first, second terminal group of plate two sides in metal isolation in isolation, in current manufacturing process,
The thimble of mold can not in mold the relative position of the above-mentioned three of stationary positioned simultaneously, namely single injection-molded can not be passed through
Above-mentioned three is molded as one structure.No. 201410395693.9 patent application of the People's Republic of China (PRC) discloses one kind
USB3.1 Type C type connector, the manufacturing process for using upper and lower plastic body fission molding finally to assemble solve small size
The manufacture problem of complex structural member, but its in terms of the Structural Integrity of connector entirety there is also some problems, upper and lower two groups
Conducting end submodule group needs to be integrated by metalwork to hold.For another example the People's Republic of China (PRC) the 201510379998.5th is special
Benefit application is solves the problems, such as above structure integraty, by middle plate and above and below middle plate by the way of injection molding three times
Two groups of conductive terminals of two sides are shaped to an entirety, but its injection molding process is more, has an impact to the yield of product, and excessive
Ground occupies injection molding machine resource, keeps cost of goods manufactured high.
Summary of the invention
The application's is designed to provide a kind of positive anti-plug USB connector of post forming formula and its manufacturing method, the USB
Connector only needs injection molding twice that can produce product, significantly reduces manufacturing cost, improves production efficiency and produce
Product yield.
For this purpose, this application provides a kind of positive anti-plug USB connectors of post forming formula, including in first end subgroup, isolation
Plate, by the first end subgroup be isolated in plate vertical direction interval superposition after injection molding first insulator, be installed on
The first insulator is located at second end subgroup in the isolation on plate side and by the first insulator and described second
The second insulator that terminal group injection molding is integrated, first, second terminal group are located at described in vertical direction
The two sides of plate in isolation, the first insulator are being formed with terminal position slot close to plate side in the isolation and are being spaced convex
Platform, first, second terminal group respectively include the first, second holding parts and distinguish from first, second holding parts both ends
The first, second weld part and the first, second contact portion extended to form, the holding parts of the second end subgroup at least partly position
In in the terminal position slot of the first insulator, second contact portion is molded again after being resisted against on the spaced-apart bosses surface
Form the second insulator.
For this purpose, present invention also provides a kind of positive anti-plug USB connector manufacturing methods of post forming formula, including walk as follows
It is rapid:
Step 1: plate in offer first end subgroup, isolation, the first end subgroup is including the first holding parts and described in
First holding parts both ends each extend over to form the first contact portion, the first weld part, the first contact portion of the first end subgroup,
One weld part is connected separately with material strip, and plate corresponds to first contact portion side and is connected with middle sheet feeding belt in the isolation；By institute
State first end subgroup be isolated in plate in vertical direction be spaced superposition after carry out first time injection molding operate to be formed first absolutely
Edge body, the first insulator are located at plate side in the isolation and are formed with terminal position slot and spaced-apart bosses；
Step 2: the material strip of excision first end subgroup both ends connection, provides second end subgroup, the second end subgroup includes
It second holding parts and each extends over to form the second contact portion, the second weld part from second holding parts both ends, second weldering
Socket part one end is connected with material strip；Second holding parts of several conductive terminals of the second end subgroup are at least partially positioned in institute
It states in terminal position slot, the second contact portion of the second end subgroup is resisted against on the surface of the spaced-apart bosses；
Step 3: by plate is formed with first insulator in the first end subgroup, isolation the first assembly and being installed on
Second end subgroup in the first insulator carries out second of injection molding operation and forms second insulator, and described second absolutely
First assembly and second end subgroup cladding fixing are an entirety by edge body.
Compared to the prior art, the positive anti-plug USB connector of the application post forming formula and its manufacturing method are first by first end
Subgroup be isolated in plate be integrally formed to form first insulator, and on the surface of first insulator plate side in the isolation
Terminal position slot and spaced-apart bosses are formed, then the second end subgroup for cutting off front end material strip is positioned in the terminal position slot
, short circuit at random to prevent not-go-end, meanwhile, the second end subgroup that will be positioned in first insulator carries out injection molding again
Complete the Shooting Technique of product.Solve the prior art, because can not the first, second terminal group of stable position, need to carry out repeatedly
Injection molding operates brought complicated process and poor efficiency.
