Description
[technical field]
The present invention relates to a kind of manufacturing approach of terminal, particularly a kind of manufacturing approach 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 manufacturing approach 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 said terminals; Make these two kinds of said terminals be connected in said strip with different height; Thereby cause said strip of when material folding frangible and cause said terminal distortion not, cause said terminal to receive meaningless damage, thereby might influence normally the carrying out of said terminal successive process (be difficult for during such as said terminal assembling to hole etc.); Expend unnecessary man-hour and increased, also reduced production efficiency.
To the existing defective of the manufacturing approach of above electric connector terminal, the experience that this creator combines self research and development and makes, active research, improvement create a kind of manufacturing approach of new electric connector terminal, to overcome the problems referred to above.
[summary of the invention]
To the variety of problems that background technology faced; The object of the present invention is to provide a kind of manufacturing approach 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 that the assembling minimizing in man-hour of electric connector is half the, reduced mould development expense and production cost again, improved production efficiency; Utilize first to prejudge groove and second and prejudge groove and 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 manufacturing approach of electric connector terminal; It is characterized in that; May further comprise the steps: step 1: a sheet metal is provided, forms a strip, upwards arrange a plurality of first polyphone portions and a plurality of second polyphone portion of being provided with at interval by said strip through bar stock cutting by punching; And the height of the said first polyphone portion is lower than the said second polyphone portion; The top of the said first polyphone portion is connected to form a first terminal, and the top of the said second polyphone portion is connected to form one second terminal, and said the first terminal and said second terminal form a main part respectively; Said second terminal is provided with one second linking arm from its said main part extension, and said second linking arm just part is positioned at below the said main part of said the first terminal; Step 2: the connecting place with said the first terminal and said first polyphone portion top is first height; Highly the said first polyphone portion and the said second polyphone portion being carried out punching out from first forms first and prejudges groove; Connecting place with said second terminal and said second polyphone portion top is second height, highly the said second polyphone portion is carried out punching out formation second from second and prejudges groove; Step 3: highly each said first is prejudged groove and cut from first, the said first polyphone part of each said the first terminal and below is left, and the said second polyphone portion is separated with the said strip of below; Step 4: highly each said second is prejudged groove and cut from second, the said second polyphone part of each said second terminal and below is left.
Compared with prior art; The manufacturing approach of electric connector terminal of the present invention through in the said polyphone of each of said strip portion first highly the place be provided with said first and prejudge groove; And highly locate to be provided with said second in second of the said second polyphone portion and prejudge groove; Prejudge groove and successively cut thereby prejudge groove and said second, thereby avoid said terminal to take place because of discontinuity equalization causes the situation of said terminal distortion to said first; And be connected with the said terminal of two kinds of different sizes on the said strip; On a said strip, use a mold can produce two kinds of different said terminals simultaneously; Said electric connector one-shot forming two row's stitch; Man-hour has been saved half in assembling, has reduced mould development expense and manufacturing cost again, has improved production efficiency.
Your juror can all further understanding and understanding can be arranged for ease of, and to combine embodiment and accompanying drawing to elaborate the object of the invention, shape, structure, characteristic and effect thereof.
