Description
Technical field
The present invention has about a kind of electric connector, refers to a kind of USB socket electric connector especially.
Background technology
Universal serial bus (UniversalSerialBus is called for short USB) is the three C products such as computer, mobile phone, camera are commonly the most the popular specification used at present.Current system has the highest city with USB2.0 transmission standard and accounts for rate.Along with the demand of transmission speed, current developed new spec, transmission speed faster USB3.0 also little by little come into the market.
In general, USB comprises the second terminal of quaternate the first terminal and five group, considering at present due to assembling, normally assemble with the mode of insert molding (insert-molding) and insulating body for one group, and another group plugs mode to assemble.The pin that such existence plugs is easily skew, and the cost of labor of assembling is higher.
If for automatically, assembled in order by two kinds of terminals with ejection formation, current technology must be developed a set of new mould and develop the excision tool automatically cut more than material strip.But the cost of mold developing and excision tool is high thus add the cost of making, must sells with higher price and lose the competitiveness in market.
Therefore, it is desirable to a kind ofly to reduce cost of manufacture, and the USB socket electric connector of high yield, high assembling quality can be maintained.
Summary of the invention
Because the problems referred to above, the invention provides a kind of USB socket electric connector.A plurality of dull and stereotyped terminal, a plurality of flexible terminal and an insulating body.Dull and stereotyped terminal comprises one first contact-segment, one first linkage section and one first welding section, wherein a side-line of the first linkage section is extended by the first contact-segment, and with the first contact-segment in bending, the first welding section is extended by the opposite side of the first linkage section, and with the first linkage section in bending.Flexible terminal is arranged between dull and stereotyped terminal alternately, and flexible terminal comprises one second contact-segment, one second linkage section and one second welding section.One side-line of the second linkage section is extended by the second contact-segment, and with the second contact-segment in bending, the second welding section is extended by the opposite side of the second linkage section, and with the second linkage section in bending.Insulating body comprises a hyoplastron and a pedestal, and hyoplastron is extended by one end of pedestal.First contact-segment and the second contact-segment system are fixed on hyoplastron, and expose at least one part, and the first weld part and the second weld part system protrude from pedestal.Hyoplastron comprises a plurality of cut-off point, pedestal comprises a plurality of disconnecting unit, wherein a part for the first linkage section and a part for the second linkage section are arranged adjacent, and the front end system of the first contact-segment corresponds to cut-off point between disconnecting unit.
In one embodiment, before dull and stereotyped terminal, flexible terminal and insulating body are assembled, dull and stereotyped terminal and elastic tip subsystem connect material strip with one first and one second connection material strip is connected and is a material strip plate.First connects material strip comprises a plurality of material contact, material contact corresponds to cut-off point, connects the first contact-segment in a mode connected, and the second connection material strip comprises a plurality of material and meets portion, the material portion of connecing corresponds to disconnecting unit, each material portion of connecing connect the first linkage section and the second linkage section at least one of them.
In one embodiment, insulating body is fixed on insert molding (insertingmolding) in material strip plate system, makes dull and stereotyped terminal, elastic tip subsystem modelling fixes, and the pedestal of insulating body comprises an opening, insert for tool.After completing insert molding, the mode of turnover or backfin up and down can be utilized, make the first connection material strip and second connect material strip and depart from insulating body.
In one embodiment, second connects material strip comprises a plurality of fluting, and fluting corresponds respectively to the first welding section and the second welding section.Namely, the first welding section and the second welding section system connect material strip by second and go out shape, after the first welding section and the bending of the second welding section, leave fluting.
In one embodiment, the first welding section and the second welding section system connect material strip by second and to bend in (tearing) mode of tearing and formed.So, only need once to bend, the pin position alignment of the first welding section and the second welding section, and be easy to dip (dualin-linepackage, DIP).
In one embodiment, dull and stereotyped terminal, flexible terminal, first connect material strip, second and connect material strip system with integration stamped molded.
In one embodiment, the second connection material strip also comprises a plurality of protection pin, and protection pin and the second material strip bend at angle.
In one embodiment, USB socket electric connector more comprises a metal shell, and metal shell is located in the outside of insulating body.Further, metal shell also has a bonnet.To increase the area of shielding, promote the effect suppressing electromagnetic interference (electromagneticinterference, EMI) or radio frequency interference (radiofrequencyinterference, RFI).
Further, metal shell comprises one first wall, one second wall, one the 3rd wall and a wall.First wall, the second wall, the 3rd wall and wall are connected and surround a grafting space, the below that first wall is positioned at the top of insulating body, the second wall is positioned at insulating body, first wall and the second wall are formed with at least one projection, and projection is extended towards grafting space by the first wall.
Further, metal shell first wall is formed with a short slot.Short slot at least makes the power supply terminal in dull and stereotyped terminal or flexible terminal expose.So, when avoiding USB socket electric connector to be connected with plug, power supply terminal contacts with metal shell and produces short circuit, more avoids the problem of the overheated or element damage caused because of short circuit.
In sum, in above embodiment, be that dull and stereotyped terminal, flexible terminal are connected form material strip plate through the first connection material strip, the second connection material strip, and directly can carry out insert molding, and decrease mould development cost.In addition, the welding section of dull and stereotyped terminal and flexible terminal is directly directly bend shaping by metal sheet, comparatively can align and be beneficial to encapsulation in pin position.And unnecessary materials and parts, directly with pulling folding and separable up and down, thus not needing exploitation excision tool, making in overall process more economical, and can better the market competitiveness.
