Abstract
The invention discloses a rolling terminal and a manufacturing method thereof. The rolling terminal is provided with a columnar structure and comprises a base part and a pressing part, wherein the base part and the pressing part are formed integrally, and the pressing part is defined to be a closed cylinder. According to the rolling terminal, on the premise that a product function and a final structure of the terminal are unaffected, a metal material tablet is subjected to punch forming, continuous electroplating and secondary punch forming, so that an adhesion effect of an electroplated layer in the rolling terminal is stable, and the electroplating effect is uniform.
Description
Technical field
The present invention relates to the manufacture method of electrical connector assembly, especially relate to a kind of volume nose circle and manufacture method thereof.
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 plating method to satisfy the conduction demand.In the prior art, after the sheet material process diel moulding, in electroplating bath, terminal is carried out immersion plating and forms film plating layer, owing to the full-closed structure reason of volume nose circle, adopting the immersion plating mode to carry out when gold-plated, because the restriction of the sub-inner space of volume nose circle, immersion plating liquid in volume nose circle lacks convection current, cause the inner inhomogeneous phenomenon of film plating layer thickness meeting of volume nose circle, the zone that has almost is not attached with Gold plated Layer, has reduced product quality.
Summary of the invention
Based on this, be necessary the problem for the existence of above-mentioned background technology, a kind of volume nose circle and manufacture method thereof of Improving The Quality of Products is provided.
For achieving the above object, the invention discloses a kind of volume nose circle, volume nose circle is prismatical structure, and described volume nose circle attached bag is drawn together base portion and pressing section, and described base portion and pressing section are one-body molded, and described pressing section encloses and is the closed cylinder.
Among embodiment, described volume nose circle is cylindrical structure therein, and described pressing section encloses and is the closed cylinder.
Therein among embodiment, described pressing section junction one side is provided with and holds protuberance, and described pressing section junction opposite side is provided with and holds recess, describedly holds protuberance and holds the recess coupling and dock.
Among embodiment, described base portion one side is connected with strip therein.
Among embodiment, offer gear hole on the described strip therein.
For achieving the above object, the invention discloses a kind of manufacture method of volume nose circle, it may further comprise the steps:
(1), forms a coil type metal material tablet;
(2), punching press, the metal material tablet is struck out semiclosed terminal structure by the diel that has the terminal forming panel;
(3), continuous electroplating, the semiclosed terminal structure that step (2) is produced is electroplated the setting of electric current and the electroplate liquid concentration of dip plating machine being carried out according to different electrodeposited coating thickness by electroplating assembly line;
(4), punch forming, the semiclosed terminal structure of the plating in the step (3) is carried out post forming, become volume nose circle.
Among embodiment, described metal material tablet is copper or aluminium matter therein.
Among embodiment, described semiclosed terminal structure cross section is the U-shaped shape therein.
In sum, the present invention rolls up nose circle and manufacture method thereof under the prerequisite that does not affect product function and final terminal structure, the metal material tablet is by punch forming, continuous electroplating and two times punch moulding, so that the inner electrodeposited coating adhesion effect of volume nose circle is stablized, electroplating effect is even.

Embodiment
For further understanding feature of the present invention, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
As shown in Figures 1 to 4, the present invention rolls up nose circle and is cylindrical structure, described volume nose circle attached bag is drawn together base portion 10 and pressing section 20, described base portion 10 is one-body molded with pressing section 20, described pressing section 20 encloses and is the closed cylinder, and described pressing section 20 junctions, one side is provided with and holds protuberance 21, and described pressing section 20 junction opposite sides are provided with and hold recess 22, the described protuberance 21 that holds docks with holding recess 22 couplings, so that pressing section 20 is fixed-type; Described base portion 10 1 sides are connected with strip 30, offer gear hole 31 on the described strip 30, with the position that holds as the sub-transmission of volume nose circle, the convenient transmission.
A kind of manufacture method of volume nose circle comprises the steps:
(1), forms the copper or aluminum metal material tablet of a coil type;
(2), punching press, namely for the first time moulding strikes out semiclosed terminal structure with the metal material tablet by the diel that has the terminal forming panel, described semiclosed terminal structure cross section is the U-shaped shape;
(3), continuous electroplating, the semiclosed terminal structure that step (2) is produced is electroplated by electroplating assembly line, according to different electrodeposited coating thickness electric current and the electroplate liquid concentration of dip plating machine are carried out the setting of analog value, reduce the translational speed of semiclosed terminal structure, the electric current that increases electroplating machine gets final product the thickness of corresponding increasing electrodeposited coating, semiclosed terminal structure is electroplated in dip plating machine, so that the electroplate liquid in the dip plating machine fully contacts with the inner space of semiclosed terminal structure, reduce the problem that semiclosed terminal structure inside fully is not attached with electrodeposited coating;
(4), punch forming, the semiclosed terminal structure of the plating in the step (3) is carried out post forming, become volume nose circle, strip 30 parts of removing out more semiclosed terminal structure.
Particularly, immersion plating technology is identical with existing immersion plating technology, stamping forming semiclosed terminal structure places on the electroplating assembly line for the first time, the gear hole 31 of semiclosed terminal structure places on the production line gear, place in the electroplate liquid of electroplating machine, the for the first time stamping forming semiclosed terminal structure of gear driven transmits, and finishes electrodeposited coating in the transport process and adhere to operation in electroplate liquid.
During the punch forming of metal material tablet process step (2), the semiclosed terminal structure of formation is U-shaped, is convenient to electroplate.In the situation that does not change existing electroplating technology, whole technique can be so that the electrodeposited coating adhesion effect of volume nose circle be stable, and electroplating effect is even.
The above embodiment has only expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
