Description
Relevant a kind of electric connector of the present invention and manufacture method thereof, referring in particular to a kind of is the electric connector and the manufacture method thereof of one with conducting terminal and insulating body fluid-tight engagement by ejection formation.
Continuous development along with communication network technique and portable computer, data transmission between distinct electronic apparatuses is more and more frequent, the data transmission quantity of its unit interval is more and more big, and the trend of computer miniaturization makes computer itself only have limited inner space, make that relatively the interval between its intraware volume and the assembly is more and more little, therefore, be widely used in the electric connector of data transmission on the computer, had more than the numbers of poles and the telecommunication terminal of very high density.In existing electric connector making method, usually adopt inserted mode that terminal in a row directly is inserted in Primary Location in the electric connector insulating body, exert pressure and terminal further is pressed into interfere and combines in terminal tails again, with the surface adhering technology terminal tails is soldered on the circuit board more afterwards with insulating body.Relative manufacturing process can be consulted cases such as No. the 77208350th, 79204276,80213361,80209366, TaiWan, China patent application and disclose.But, machinery through so being pressed into the finished connector product that the winding mode obtained and electric property possibly can't reach predetermined standard, one, because of the terminal containing slot of insulating body more and more many, and arrange more and more close, so the uniformity that each accepting groove cell wall penetrates situation on processing procedure is difficult for guaranteeing, when making interval between wall and the wall wide in case the accepting groove wall is crossed thin, terminal shows can't obtain strong fix therein.Moreover, inserting the fixing mode of winding must can realize by mutual extrusion effect between terminal and insulating body, but this kind squeezing action very easily causes mechanical damage to terminal and accepting groove wall, as producing crack or burr on the terminal, accommodating wall by scratch, terminal can't be isolated each other effectively mutually even, and then influences the joint electrical quality of electric connector.In addition, the adhesion technology is the many and high electric connector of density for number of terminals, require its terminal to have very high same flatness, so can guarantee to have good welding quality, yet existing forced winding mode, it can make the welding afterbody of terminal stressed and bend and cause its same flatness to reduce when being pressed into terminal inevitably, thereby is unfavorable for that it is engaged to the operation of circuit board.
For solving these problems, industry adopts interior mold forming that electric connector terminal and insulating body are bonded together, relevant prior art can be consulted United States Patent (USP) the 5th, 274,918,4,775,333,5,052,936,5,074,039,5,653, cases such as No. 611, conducting terminal is positioned in the mould by terminal material belt but these technology are many, yet too high relatively because of conducting terminal density, conducting terminal size and mechanical strength are less, under plastic solution impacts, conducting terminal can produce certain deformation, and this distortion also can cause the location of conducting terminal in insulating body deviation or make the conducting terminal weld part irregular to some extent, and is unfavorable for this electric connector and docks butt joint between the electric connector or the welding operation between conducting terminal and circuit board.
The object of the invention is to provide a kind of conducting terminal that makes firmly to be mounted in the mould, and the manufacture method of conducting terminal distortion reaches the electric connector of method manufacturing thus when preventing injection moulding.
According to the foregoing invention purpose, electric connector making method of the present invention may further comprise the steps:
Terminal material belt and shielding casing with connecting band and positioner are provided, wherein this conducting terminal comprise the fixed part that is immobilizated in the insulating body, in fixed part one end and with the vertically extending docking section of fixed part bearing of trend and in the connecting portion of the relative end of fixed part;
The terminal material belt of certain-length is inserted in the mould, connecting band by conducting terminal and conducting terminal fixed part cooperate with the mould relative configurations and conducting terminal firmly are mounted in the mould, and the back is by being fixed in the terminal material belt group in the insulating body by ejection formation;
The connecting band of terminal material belt removed and the insulating body group that group is provided with conducting terminal is gone in the shielding casing.
Compare prior art, electric connector of the present invention connecting band by terminal material belt in forming process cooperates with the relative configurations of mould to realize Primary Location, then the firm clamping of conducting terminal fixed part is further strengthened the fixing effect of conducting terminal, can prevent effectively that like this conducting terminal from deforming when the injected plastic liquation by the upper and lower die of mould; Moreover, cooperate with the connecting band and the conducting terminal of terminal material belt by the upper and lower die of mould, but just strong fix of conducting terminal, its mould general structure relatively simply and not needs other servicing unit and can effectively reduce die cost.
