Abstract
Provided is a manufacturing method for a terminal module. According to the manufacturing method for the terminal module, terminals having undergone punch forming are arranged in two columns and then fixed in an injection molding mode. The terminal module comprises a first terminal group, a second terminal group and a first body. Every terminal of both the first terminal group and the second terminal group is integrally formed in a stamping mode and forms a fixed part, an elastic arm extending from one side of the fixed part and a welding part extending from the other side of the fixed part, and the longitudinal depth of every elastic arm is larger than the horizontal width. The first body is annularly arranged on the fixed part of every terminal in the injection molding mode, the terminals are fixed to form the two staggered columns, and the terminal module is formed.
Description
Technical field
The invention relates to a kind of terminal module being applied on electric connector, refer to especially and a kind of terminal board after punch forming is listed in after two row, then impose injection molding method fixing terminal module in addition.
Background technology
Electric connector is a kind of transmission medium of electric signal, is mainly to utilize terminal as the transmission between electric signal.In general, electric connector is to be mainly arranged on circuit board, as the expansion of ancillary equipment, as memory module etc.
Existing being used for is connected in the electric connector on circuit board by memory module, is commonly called as DDR, roughly distinguishes and has two kinds of kenels, and a kind of is vertical DDR, and a kind of is horizontal DDR.So-called vertical DDR, inserts after electric connector exactly, forms stand-type meaning and is formed with an angle with circuit board.And horizontal DDR inserts after electric connector exactly, be parallel to each other with circuit board.In vertical DDR use, easily cause the waste in space, therefore rare on the electronic product in less space, mostly by horizontal DDR, replaced.
Common horizontal DDR electric connector, probably distinguishes and has two classes again at present, mainly by the molding mode of metal terminal, is distinguished, and a kind of is plug-in type, and another kind is bendable.
As shown in Figures 1 and 2, be the manufacturing process schematic diagram of the made electric connector of 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 forms an inserting part B on plug in terminals A, and the upper lower edge at inserting part B has at least protruded out a hangnail C, to insert by inserting part B after insulating body (not representing in diagram), utilize hangnail C to thrust in plastic body, and then reach fixing effect.
This kind used the electric connector of plug in terminals, in preparation technology, is mainly distinctly by terminal punch forming and by after plastic body ejection formation, more one by one terminal is fixed on plastic body with inserted mode.
Only, this kind of plug in terminals A is when carrying out signal transmission, when signal transmits by terminal, can cause signal to branch in inserting part B, thereby in the process that signal is transmitting, cannot directly pass through fast 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 use in the electric connector of high-speed transfer.
Moreover, when plug in terminals A is when inserting plastic body, need to fix in plastic body by hangnail C, therefore, in the process of inserting, the destruction that also can cause plastic body, makes 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, is mainly to utilize after impact style moulding, then in pressing and bending mode, bending goes out after required form, and the mode of recycling ejection formation is linked those bendable terminals D.
Use the electric connector of this kind of bendable terminal, need, by after the first terminal module, the second terminal module and plastic body moulding out of the ordinary, assembled.
Only, this kind of bendable terminal D, need can reach the effect of moulding by the mode of bending.But, because metal itself has certain stress, when terminal is in Forging Process, easily produce stress and the phenomenon such as concentrate; Moreover, because metal itself has certain ductility, when the strength of exerting pressure is greater than the ductility of metal material itself, easily cause the phenomenon of resilience in Forging Process, cause the evenness of those injection-molded terminals poor, and also easily have the phenomenon of distortion.Especially in assembling process, more easily because assembling accidentally cause collision, and cause the distortion of terminal.
This kind of mode, easily causes technologic badly, has not only affected technique yield, causes 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 kenels, produced the problem of various different kenels, such as carrying out, high-speed transfer, terminal stress are concentrated, technique rate is not good, easily distortion etc. of terminal.
