Abstract

The invention discloses a rolling terminal and a making method thereof. The rolling terminal comprises a rolling bar; insertion bars vertically extended with the bar are uniformly arranged on the bar; tail ends of the insertion bars are outwards lapped over; and only one surface of the insertion bars is coated with a clad layer. On the premise of no influence on product function and a final terminal structure, a plate is formed by stamping, electroplated and formed by secondary stamping, so an electroplating process of the terminal is changed from immersion plating to brush plating, and the terminal provided with the insertion bars of which only one surface is coated with the clad layer is finally formed, and the electroplating cost is greatly reduced.

Description

Volume nose circle and preparation method thereof

Technical field

The present invention relates to a kind of volume nose circle and processing method thereof, relating in particular to is not a kind ofly influencing product function and final terminal structure, and the sub-manufacture method of volume nose circle that can significantly reduce cost.

Background technology

Volume nose circle all is to contact with male usually, and in order to improve the conductivity of terminal, the contact zone all can adopt gold-plated mode to satisfy the conduction demand.In the prior art, as shown in Figure 4, after the sheet material process diel moulding, in electroplating bath terminal is carried out immersion plating and forms coatings, because the reasons in structure of product, gold-plated mode all adopts the immersion plating mode, and just make that the surfaces externally and internally of terminal all can be gold-plated like this, and during actual the use, only need terminal and male contact site gold-plated, promptly only need the medial surface and the male contact site of terminal to carry out gold-plated getting final product.Existing mode has caused the increase of electroplating area, has improved gold-plated cost, and the coating loss is big.

Summary of the invention

The objective of the invention is to propose a kind of volume nose circle and preparation method thereof.

Purpose of the present invention will be achieved by the following technical programs:

A kind of volume nose circle comprises, a volume circle bar bar is evenly equipped with bar bar vertical extent on the bar bar and patches bar, and the described terminal outwards turnover that patches bar describedly patches that bar has and only have one side to be coated with coating.

A kind of manufacture method of rolling up nose circle comprises the steps,

Step 1: punching press strikes out sheet material the profile plate of terminal moulding bar by the diel that has the terminal forming panel;

Step 2: electroplate, the tabular terminal of section bar that step 1 is produced is electroplated by electroplating assembly line, according to different thickness of coating the speed and the electric current of brush plating machine carried out the setting of analog value, make the bonding pad that patches bar of terminal contact with the golden cloth of the brush on the plating line, make the one side of contact brush coating, reach single face and electroplate requirement; The size of the golden cloth of described brush is provided with according to the required Gold plated Layer size of bar that patches of terminal;

Step 3: punch forming, the electrodeposition-type sheet material in the step 2 is carried out post forming, become volume nose circle, remove all the other coupling parts of sheet material.

Beneficial effect of the present invention is mainly reflected in: under the prerequisite that does not influence product function and final terminal structure, adopt the mode of post forming, structure before the change terminal is electroplated earlier, make the terminal electroplating technology change brush plating into by immersion plating, thereby electroplate area by the two-sided single face that changes into, reduced electroplating cost greatly.

Embodiment

The invention provides a kind of volume nose circle, as shown in Figure 1, comprise, a volume circle bar bar 3 is evenly equipped with bar bar 3 vertical extent on bar bar 3 and patches bar 1, and the described end 11 that patches bar 1 outwards turn down, and the described bar 1 that patches has and only has and simultaneously is coated with coating.

A kind of manufacture method of rolling up nose circle as shown in Figure 5, comprises the steps,

Step 1: punching press, i.e. moulding for the first time strikes out the profile plate of terminal moulding bar with sheet material by the diel that has the terminal forming panel, as shown in Figure 2.

Step 2: electroplate, the tabular terminal of section bar that step 1 is produced is electroplated by electroplating assembly line, according to different thickness of coating the speed and the electric current of brush plating machine carried out the setting of analog value, reduce the translational speed of terminal sheet material, the electric current that increases the brush plating machine can strengthen the thickness of coating accordingly, make the bonding pad that patches bar of terminal contact, make the one side of contact brush coating, reach single face and electroplate requirement with the golden cloth of the brush on the plating line; The size of the golden cloth of described brush is provided with according to the required Gold plated Layer size of bar that patches of terminal;

Step 3: punch forming, the electrodeposition-type sheet material in the step 2 is carried out post forming, become volume nose circle, as shown in Figure 3, remove all the other coupling parts 2 of sheet material again.

Particularly, the brush-plating technique of brush-plating technique and prior art is identical, stamping forming sheet material places on the brush plating production line for the first time, gear hole 22 on the sheet material places on the production line gear, the gold-plated cloth of brush plating machine promptly contacts with male connecting portion 21 with the required brush of terminal Jin Qu, move on the gear driven punch forming for the first time sheet material level, start the brush plating machine, can finish the one side brush plating of sheet material.After brush plating is finished, carry out post forming, at last unnecessary coupling part 2 is removed.

During the punch forming of sheet material process step 1, the sheet material with terminal pre-profiling of formation is vertical bar shaped, is convenient to brush plating.Do not changing under the existing brush-plating technique situation, whole technology can make terminal change single-face plating into by existing two-sided coating, and convenient and swift, effect is remarkable.

The coating cost savings are more than 50%, because the difference of the thickness of coating, the shared product cost of electroplating cost be than regular meeting difference, so, the ratio that cost reduces is also different, for example gold-plated 0.025um cost can reduce by 8%, and the reduction of gold-plated 0.75um cost can reach 30%, that is to say and changes technology in this way, difference according to thickness of coating, cost is minimum to reduce by 8%, can reduce at most more than 30%, and actual and potential economic benefit promotes obviously.

And, in electroplating industry, the plating specification of same size, the electroplating velocity of brush plating is faster more than 15% than the electroplating velocity of immersion plating, and technology of the present invention has improved working (machining) efficiency greatly.

The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
