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 is all contact with male usually, and in order to improve the conductivity of terminal, contact zone all can adopt gold plating method with satisfied conduction demand.In prior art, sheet material is after diel is shaping, in electroplating bath, immersion plating carried out to terminal and form film plating layer, due to the full-closed structure reason of volume nose circle, when adopting immersion plating mode to carry out gold-plated, owing to rolling up the restriction of the sub-inner space of nose circle, immersion plating liquid in volume nose circle lacks convection current, cause volume circle terminal inner film plating layer thickness can be uneven phenomenon, some regions are not almost attached with Gold plated Layer, reduce product quality.
Summary of the invention
Based on this, be necessary for above-mentioned background technology Problems existing, a kind of volume nose circle and manufacture method thereof of Improving The Quality of Products are 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 draws together base portion and nip portion, described base portion and nip portion one-body molded, described nip portion encloses as closed cylinder.
Wherein in an embodiment, described volume nose circle is cylindrical structure, and described nip portion encloses as closed cylinder.
Wherein in an embodiment, side, described nip portion junction is provided with and holds protuberance, and described nip portion junction opposite side is provided with and holds recess, described in hold protuberance and hold recess and mate and dock.
Wherein in an embodiment, described base portion side is connected with material strip.
Wherein in an embodiment, described material strip offers gear hole.
For achieving the above object, the invention discloses a kind of manufacture method of volume nose circle, it comprises the following steps:
(1) a coil type metal material tablet, is formed;
(2), punching press, metal material tablet is struck out semiclosed terminal structure by the diel with terminal forming panel;
(3), continuous electroplating, the semiclosed terminal structure that step (2) is produced is electroplated by electroplating assembly line, according to the setting that different plating thickness carries out the electric current of dip plating machine and bath concentration;
(4), punch forming, the semiclosed terminal structure of the plating in step (3) is carried out post forming, become volume nose circle.
Wherein in an embodiment, described metal material tablet is copper or aluminium matter.
Wherein in an embodiment, described semiclosed terminal structure cross section is U-shape.
In sum, the present invention rolls up nose circle and manufacture method thereof under the prerequisite not affecting product function and final terminal structure, metal material tablet is shaping by punch forming, continuous electroplating and two times punch, and the electrodeposited coating adhesion effect rolling up round terminal inner is stablized, and electroplating effect is even.

Embodiment
For feature of the present invention, technological means and the specific purposes reached, function can be understood further, 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 for cylindrical structure, described volume nose circle attached bag draws together base portion 10 and nip portion 20, described base portion 10 is one-body molded with nip portion 20, described nip portion 20 encloses as closed cylinder, and side, described nip portion 20 junction is provided with and holds protuberance 21, and described nip portion 20 junction opposite side is provided with and holds recess 22, describedly hold protuberance 21 and hold recess 22 and mate and dock, with by fixed-type for nip portion 20; Described base portion 10 side is connected with material strip 30, and described material strip 30 offers gear hole 31, to hold a position as volume nose circle transmission, conveniently to transmit.
A manufacture method for volume nose circle, comprises the steps:
(1) the copper or aluminum metal material tablet of a coil type, is formed;
(2), punching press, namely first time is shaping, and metal material tablet is struck out semiclosed terminal structure by the diel with terminal forming panel, and described semiclosed terminal structure cross section is U-shape;
(3), continuous electroplating, the semiclosed terminal structure that step (2) is produced is electroplated by electroplating assembly line, according to different plating thickness, the electric current of dip plating machine and bath concentration are carried out to the setting of analog value, reduce the translational speed of semiclosed terminal structure, the electric current increasing electroplating machine gets final product the thickness of corresponding increasing electrodeposited coating, semiclosed terminal structure is electroplated in dip plating machine, electroplate liquid in dip plating machine is fully contacted with the inner space of semiclosed terminal structure, reduces the problem that semiclosed terminal structure inside is not fully attached with electrodeposited coating;
(4), punch forming, the semiclosed terminal structure of the plating in step (3) is carried out post forming, becomes volume nose circle, then go out material strip 30 part of semiclosed terminal structure.
Particularly, immersion plating technology is identical with existing immersion plating technology, first time stamping forming semiclosed terminal structure is placed on electroplating assembly line, the gear hole 31 of semiclosed terminal structure is placed on production line gear, be placed in the electroplate liquid of electroplating machine, gear driven first time stamping forming semiclosed terminal structure transmission, completes electrodeposited coating attachment operation in electroplate liquid in transport process.
Metal material tablet is through step (2) punch forming, and the semiclosed terminal structure of formation is U-shaped, is convenient to plating.When not changing existing electroplating technology, whole technique can make the electrodeposited coating adhesion effect rolling up nose circle stablize, and electroplating effect is even.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It 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.
