Description
Technical field
The invention relates to a kind of terminal module be applied on electric connector, refer to especially a kind of terminal board after punch forming is listed in two row after, then impose the terminal module that injection molding method fixed.
Background technology
Electric connector is a kind of transmission medium of electric signal, mainly utilizes terminal as the transmission between electric signal.In general, electric connector is mainly arranged on circuit board, as the expansion of ancillary equipment, as memory module etc.
The existing electric connector being used for being connected to by memory module on circuit board, is commonly called as DDR, and roughly distinguishing has two profiles state, and one is vertical DDR, and one is horizontal DDR.So-called vertical DDR is exactly, after inserting electric connector, form stand-type meaning and be namely formed with an angle with circuit board.And after horizontal DDR inserts electric connector exactly, be parallel to each other with circuit board.Due in vertical DDR use, easily cause the waste in space, therefore rare on the electronic product in less space, mostly replaced by horizontal DDR.
Horizontal DDR electric connector common at present, general differentiation has two classes again, and the molding mode primarily of metal terminal is distinguished, and one is plug-in type, and another kind is bendable.
As shown in Figures 1 and 2, the manufacturing process schematic diagram of electric connector made by known employing plug in terminals and the schematic diagram of plug in terminals.As shown in the figure, those plug in terminalss A, mainly one-body molded by impact style, this kind of plug in terminals A mainly forms an inserting part B on plug in terminals A, and at least protruded out a hangnail C at the upper lower edge of inserting part B, after inserting insulating body (not representing in diagram) by inserting part B, utilize hangnail C to thrust in plastic body, and then reach fixing effect.
This kind uses the electric connector of plug in terminals, in preparation technology, mainly out of the ordinary by terminal punch forming and by after plastic body ejection formation, then is fixed on plastic body with inserted mode by terminal one by one.
Only, this kind of plug in terminals A is when carrying out signal transmission, when signal is transmitted by terminal, signal can be caused to branch in inserting part B, thus when signal is in the process transmitted, cannot fast directly by plug in terminals A, and be delivered on circuit board, therefore this kind of plug in terminals only can provide the electric connector of general transmission speed to use, and cannot be used in the electric connector of high-speed transfer.
Moreover, when plug in terminals A is when inserting plastic body, needing to fix in plastic body by hangnail C, therefore in the process inserted, also can cause the destruction of plastic body, making plug in terminals A have loosening possibility.
Referring to shown in Fig. 3 and Fig. 4, is the manufacturing flow chart of electric connector and the schematic diagram of bendable terminal of known use bendable terminal.As shown in the figure, those bendable terminals D, after mainly utilizing impact style shaping, then in pressing and bending mode, after bending goes out required form, those bendable terminals D is linked by the mode of recycling ejection formation.
Use the electric connector of this kind of bendable terminal, need the first terminal module, the second terminal module and plastic body is distinctly shaping after, assembled.
Only, this kind of bendable terminal D, need can reach shaping effect by the mode of bending.But, because metal itself has certain stress, when terminal is in Forging Process, the phenomenons such as easy generation stress is concentrated; Moreover, because metal itself has certain ductility, when the strength of exerting pressure in Forging Process is greater than the ductility of metal material itself, easily cause the phenomenon of resilience, cause the evenness of those injection-molded terminals poor, and also easily have the phenomenon of distortion.Especially in an assembling process, more easily accidentally cause collision because of what assemble, and cause the distortion of terminal.
This kind of mode, easily causes technologic bad, not only have impact on process yields, cause the raising of fraction defective, more can cause the increase in manufacturing cost.
In known technology, due to the terminal module of electric connector, according to the terminal molding mode of various different kenel, create the problem of various different kenel, such as cannot carry out high-speed transfer, terminal stress is concentrated, technique rate is not good, terminal is easily out of shape etc.
