Description
[technical field]
The present invention relates to a kind of manufacture method of terminal, particularly a kind of manufacture method of the connector terminals in order to the plant electronic cards.
[background technology]
As everyone knows, terminal is as the medium of signal of telecommunication transmission, and its effect is that the signal of telecommunication with an end is sent to the other end, makes two ends form a path.The opinion with electric connector, its terminal that is provided with is that an electronic component is electrically connected on the circuit board.
At present, the way that industry is general is that punching press forms a kind of terminal on a strip.When if this electric connector need be installed the terminal of two kinds of difformity specifications, then need adopt two molds to come these two kinds of terminals of moulding respectively, thereby increase the mould development expense, and then improve production cost.
For addressing the above problem, the follow-up manufacture method of developing another kind of electric connector terminal again, it uses two kinds of different terminals of a mold moulding on a strip.Planform difference because of two kinds of described terminals, make these two kinds of described terminals be connected in described strip with different height, thereby cause described strip of when material folding frangibility and cause described terminal distortion not, cause described terminal to be subjected to meaningless damage, thereby might influence normally the carrying out of described terminal successive process (be difficult for during such as described terminal assembling to hole etc.), expend unnecessary man-hour and increased, also reduced production efficiency.
At the existing defective of the manufacture method of above electric connector terminal, this creator is in conjunction with self research and development and the experience made, and active research, improvement create a kind of manufacture method of new electric connector terminal, to overcome the problems referred to above.
[summary of the invention]
At the variety of problems that background technology faced, the object of the present invention is to provide a kind of manufacture method of electric connector terminal, it is connected with a plurality of terminals of two kinds of different sizes on a strip, can on a strip, use a mold to produce two kinds of different terminals, electric connector is once assembled two kinds of different terminals, make the assembling of electric connector reduce half man-hour, reduced mould development expense and production cost again, improved production efficiency; Utilize the first pre-fault trough and the second pre-fault trough to carry out priority folding material, to avoid the electric connector terminal strip directly to roll over when material discontinuity equalization and cause the terminal distortion, can solve the problem that the company material place of electric connector terminal strip has differing heights to cause strip to fracture together again.
To achieve these goals, in the present invention to adopt following technical scheme:
A kind of manufacture method of electric connector terminal, it is characterized in that, may further comprise the steps: step 1: a sheet metal is provided, form a strip through bar stock cutting by punching, upwards arrange a plurality of first polyphone portions and a plurality of second polyphone portion of being provided with at interval by described strip, and the height of the described first polyphone portion is lower than the described second polyphone portion, and the top of the described first polyphone portion is connected to form a first terminal, and the top of the described second polyphone portion is connected to form one second terminal; Step 2: the connecting place with described the first terminal and described first polyphone portion top is first height, highly described first polyphone portion and the described second polyphone portion are carried out the punching out formation first pre-fault trough from first, connecting place with described second terminal and described second polyphone portion top is second height, highly the described second polyphone portion is carried out punching out from second and forms the second pre-fault trough; Step 3: highly each described first pre-fault trough is cut from first, the described first polyphone part that makes each described the first terminal and below from, and the described second polyphone portion is separated with the described strip of below; Step 4: highly each described second pre-fault trough is cut from second, the described second polyphone part that makes each described second terminal and below from.
Compared with prior art, the manufacture method of electric connector terminal of the present invention by in the described polyphone of each of described strip portion first highly the place be provided with the described first pre-fault trough, and in the described second polyphone portion second highly the place be provided with the described second pre-fault trough, thereby the described first pre-fault trough and the described second pre-fault trough are successively cut, thereby avoid described terminal to take place because of discontinuity equalization causes the situation of described terminal distortion; And be connected with the described terminal of two kinds of different sizes on the described strip, on a described strip, use a mold can produce two kinds of different described terminals simultaneously, described electric connector one-shot forming two row's stitch, man-hour has been saved half in assembling, reduce mould development expense and manufacturing cost again, improved production efficiency.
Your juror can all further understanding and understanding can be arranged for ease of, and to elaborate with accompanying drawing in conjunction with the embodiments purpose of the present invention, shape, structure, feature and effect thereof.
