The present invention provides a kind of manufacturing process of fuse integrated formula binding post, a kind of manufacturing process of fuse integrated formula binding post, including outer cap, binding post, comprises the following steps：A, the outer cap is forged and pressed so that it is recessed on the inside of the outer cap, and protrusion forms projection accordingly in outside；B, the binding post includes portion inside and external connection portion, and the portion inside stamps out the combined hole matched with projection described in step A, and the external connection portion stamps out the external hole with external electrical connections；C, the projection is put into the combined hole, and the projection is by being welded to connect the combined hole.The projection connects the combined hole by Surface Welding at High Temperature.The projection passes through combined hole described in ultrasonic bonding connection.Beneficial effect：Being welded to connect for outer cap and binding post is realized, increases contact area, so as to the voltage and current capacity of increased fuse.And combine simply, beneficial to follow-up fuse automated production.
Description
Technical field
The present invention relates to fuse technologies field, more particularly to a kind of manufacturing process of fuse integrated formula binding post.
Background technology
Fuse refers to when electric current exceedes setting, melt is fused with heat caused by itself, the one of disconnecting circuit
Kind electrical equipment, fuse are also known as fuse.Fuse is after exceeding setting for a period of time according to electric current, with heat caused by its own
Amount makes Melt molten, so that circuit disconnects；With a kind of circuit brake made of this principle.Fuse is widely used in height
It is using most common as short circuit and the protector of overcurrent in low-voltage distribution system and control system and electrical equipment
One of protector.In the prior art, typically directly it is processed with machine, so causes the waste of copper material.Separately fabricated cap out
And binding post, then outer cap and binding post are riveted；The connection terminal of fuse typically uses riveting to outer cap, this
Sample easily causes the insufficient contact of connection terminal and outer cap, can greatly be reduced by electric current, so as to reduce fuse
Electric property.
The content of the invention
The present invention provides a kind of manufacturing process of fuse integrated formula binding post, and outer cap and binding post integral type are connected
Connect, expand contact surface；While to realize that automatic assembling fuse provides early-stage preparations.
In order to solve the above-mentioned technical problem, the technical solution used in the present invention is：
A kind of manufacturing process of fuse integrated formula binding post, including outer cap, binding post, comprise the following steps：
A, the outer cap is forged and pressed so that it is recessed on the inside of the outer cap, and protrusion forms projection accordingly in outside；
B, the binding post includes portion inside and external connection portion, and the portion inside stamps out to be matched with projection described in step A
Combined hole, the external connection portion stamps out the external hole with external electrical connections；
C, the projection is put into the combined hole, and the projection is by being welded to connect the combined hole.
Further, the projection connects the combined hole by Surface Welding at High Temperature.
Further, the projection passes through combined hole described in ultrasonic bonding connection.
Further, solid solder flux auxiliary welding is used in welding process.
Further, the manufacturing process of the outer cap includes：
A, the metal derby of constant weight is cut out from metal bar；
B, the metal derby carries out hot forging pressure in profiling mould, extrudes predetermined outer cap shaped.
Preferably, the metal bar is cylindrical metal bar.
Further, the sheet metal of certain length is cut out, is extruded the sheet metal using bender or stamping technology
Portion inside and external connection portion, the portion inside and external connection portion are formed " L " shapes.
Preferably, the burr of the metal derby and sheet metal is polished using bobbing machine.
Preferably, the metal bar is copper, copper is silver-plated or copper nickel-plated metal material.
Preferably, the height of the projection is identical with the width size of the combined hole.
The present invention provides a kind of manufacturing process of fuse integrated formula binding post, and the technique realizes outer cap and terminals
Being welded to connect for son, increases contact area, so as to the voltage and current capacity of increased fuse.And combine simply, it is beneficial to
Follow-up fuse automated production.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of the manufacturing process of fuse integrated formula binding post of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, embodiments of the present invention are specifically illustrated, accompanying drawing is only for reference and explanation uses, and does not form pair
The limitation of scope of patent protection of the present invention.
As shown in figure 1, a kind of manufacturing process of fuse integrated formula binding post, including outer cap, binding post, it is described outer
The manufacturing process of cap includes：
A, the metal derby of constant weight is cut out from metal bar；
B, the metal derby carries out hot forging pressure in profiling mould, extrudes predetermined outer cap shaped.
The manufacture of binding post：The sheet metal of certain length is cut out, using bender or stamping technology by the metal
Piece extrudes portion inside and external connection portion, the portion inside and external connection portion are formed " L " shapes.
After outer cap and binding post are produced from metal material, subsequent technique comprises the following steps：
A, the outer cap is forged and pressed so that it is recessed on the inside of the outer cap, and protrusion forms projection accordingly in outside；Institute
It can be cuboid to state projection, or cylinder.
B, the binding post includes portion inside and external connection portion, and the portion inside stamps out to be matched with projection described in step A
Combined hole, the external connection portion stamps out the external hole with external electrical connections；
C, the projection is put into the combined hole, and the projection is by being welded to connect the combined hole.
In the present embodiment, the projection connects the combined hole by Surface Welding at High Temperature, or the projection passes through supersonic welding
The combined hole is connect in succession.Auxiliary welding is carried out using solid solder flux so that welding effect is more preferable in welding process；The metal
Bar is cylindrical metal bar, directly cuts out the sheet metal of round sheet, sheet metal is forged and pressed, and formation possesses lid
Outer cap.The burr of the metal derby and sheet metal is polished using bobbing machine, makes it more smooth；And beneficial to next
The processing of step.The metal bar is copper, copper is silver-plated or copper nickel-plated metal material.The height of the projection and the combined hole
Width size is identical；It ensure that the upper surface of projection is concordant with the top edge of combined hole.
Above disclosed is only presently preferred embodiments of the present invention, it is impossible to the rights protection model of the present invention is limited with this
Enclose, therefore the equivalent variations made according to scope of the present invention patent, still belong to the scope that the present invention is covered.
