Description
Technical field
The utility model is related to it is gold-plated use belt, specifically disclose a kind of belt for reducing invalid gold-plated area.
Background technology
Terminal is a kind of wiring terminal, also known as binding post, and main serve transmits electric signal or conductive, and terminal is usual
It will carry out gold-plated just coming into operation.The gold-plated main method using point plating of terminal, putting the process of plating is：Plating solution is from anode
Water pocket high pressure is ejected to annular distance and contacted with plated region, and under electric field action, main salt metal ion obtains electronics and sunk in plating solution
Product forms coating in terminal, the region that terminal contacts with plating solution.
According to the principle of plating and the structure of terminal, traditional plane belt plates with that can not be bonded at terminal back side recess
Liquid can infiltrate into the back side of terminal, and terminal can also be coated with layer gold without the gold-plated back side, i.e., gold-plated, the back of the body is carried out in inactive area
The invalid gold-plated region in face will cause valuable metals resources to be wasted, and increase production cost.
Utility model content
Based on this, it is necessary to for prior art problem, there is provided a kind of belt for reducing invalid gold-plated area, can be notable
The invalid gold-plated area in the terminal back side is reduced, reduces the wasting of resources of precious metal.
To solve prior art problem, the utility model discloses a kind of belt for reducing invalid gold-plated area, including belt
Body, belt body are in annular, and the outer surface of belt body is fixed with raised band, and the section of raised band is triangle, raised
The section triangle of band matches with the shape size of terminal back side recess.
Further, raised band is formed in one with belt body.
Further, the outer surface of belt body and raised band is fixed with layer of silica gel.
Further, the height of projection of raised band is H, 1mm≤H≤2mm.
Further, the width of raised band is L, 3mm≤L≤8mm.
Further, the section triangle drift angle of raised band is α, 90 °<α<180°.
Further, the spacing of raised band and the side of belt body one is d, between raised band and another side of belt body
Away from for D, D ≠ d.
Further, the section of raised band is isosceles triangle.
The beneficial effects of the utility model are：The utility model discloses a kind of belt for reducing invalid gold-plated area, according to
The shape of terminal back side recess is designed with the belt of pictograph projection band, and raised band, can with being brought into close contact at terminal back side recess
It is gold-plated effectively to prevent that plating solution from being carried out to the recess at the terminal back side, significantly reduces the invalid gold-plated area in the terminal back side, invalid plating
Golden area about reduces by 60%, reduces the wasting of resources of precious metal, and production cost is low, environmentally friendly.
Brief description of the drawings
Fig. 1 is overlooking the structure diagram of the present utility model.
Fig. 2 is the schematic cross-section of the A-A along Fig. 1.
Fig. 3 is conventional belt and use state comparison diagram of the present utility model.
Reference is：Belt body 100, layer of silica gel 110, raised band 200, terminal 300.
Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be further appreciated that, below
The utility model is described in further detail with embodiment with reference to accompanying drawing.
Referring to figs. 1 to Fig. 3.
The utility model embodiment discloses a kind of belt for reducing invalid gold-plated area, including belt body 100, preferably
Ground, the width of belt body 100 is 20mm, thickness 2mm, and belt body 100 is in annular, the outer surface of belt body 100
Raised band 200 is fixed with, the section of raised band 200 is triangle, and the section triangle of raised band 200 and the back side of terminal 300 are recessed
Sunken shape size matching.
Terminal 300 is disposed across on belt, is the structure of accommodating terminal 300 in conventional belt as shown in the upper figure in Fig. 3
Schematic diagram, as shown in figure below in Fig. 3, for the structural representation of accommodating terminal 300 on the utility model belt, raised band 200
It is brought into close contact with the recess at the back side of terminal 300, it is gold-plated effectively prevents that plating solution from being carried out to the recess at the back side of terminal 300, can
The invalid gold-plated area in the back side of terminal 300 is significantly reduced, reduces the wasting of resources of precious metal, reduces production cost.
Based on above-described embodiment, raised band 200 is formed in one with belt body 100, and it is new can to effectively improve this practicality
The overall stability of type.
Based on above-described embodiment, the outer surface of belt body 100 and raised band 200 is fixed with layer of silica gel 110, it is preferable that
Layer of silica gel 110 is 2mm, and layer of silica gel 110 can shield to belt body 100 and raised band 200, while can effectively carry
The high frictional force with terminal 300, the position of terminal 300 is more stable, improves machining accuracy.
Based on above-described embodiment, according to the specification of conventional terminal 300, every size of raised band 200, raised band are designed
