Wherein corresponding relation is, insulating body 101, weld cap 102, resistance wire 103, shell 104, pin electrode 105, framework
106, supporting part 107.
Detailed description of the invention
Referring to accompanying drawing 1, a kind of wire resistor, including fuse, shell, pin electrode, fuse includes insulating body 101, weldering
Cap 102, resistance wire 103, insulating body 101 can use the material such as ceramic matrix, cement matrix, insulating body according to actual needs
101 two ends installation settings have weld cap 102.Resistance wire 103 is wrapped on insulating body 101, and two ends are respectively welded at insulating body
On the weld cap 102 at 101 two ends.Weld cap 102 bottom welding has pin electrode 105, pin electrode 105 end to have supporting part 107,
Weld cap 102 bottom welding is on supporting part 107, and weld cap 102 can be made cylindric, and correspondingly, supporting part 107 makes arc plate
Shape, is beneficial to carry weld cap 102.
Insulating body 101, weld cap 102 and resistance wire 103 covering are partially exposed at institute equipped with shell 104, pin electrode 105
State outside shell 104.Shell 104 can use resin material, or plastic material, makes the shape such as square being easy to attachment, all
For common sense in the field.
Also provide for the manufacturing process of the wire resistor of the present embodiment, referring to accompanying drawing 2.
Step 201, installs weld cap.Weld cap 102 is arranged on the two ends of insulating body 101.
Step 202, is wound around and welding kesistance silk.Resistance wire 103 is wrapped in insulating body according to the requirement of resistance value
101, then the two ends of resistance wire 103 are welded on the weld cap 102 at insulating body 101 two ends, form fuse.
Some fuses are installed in the load bearing unit of framework by step 203.Framework 106 is for set previously according to wire resistor
Meter, takes the mode of blocking, each framework 106 to may be designed to some load bearing units, and each load bearing unit carries a fuse,
Can be according to the quantity needing design load bearing unit of technique and the shape of framework 106.Each load bearing unit is designed with pin electricity
Pole 105, pin electrode 105 end is designed with supporting part 107, to carry two ends weld cap 102.If weld cap 102 is cylindric, carrying
Portion 107 may be designed as circular arc sheet, to carry fuse in corresponding position.Pin electrode 105 is one-body molded with framework 106
, circular arc sheet supporting part 107 also with framework 106 integrated punching molding.Fuse is installed to each load bearing unit of framework 106
In, each weld cap 102 is all to there being pin electrode 105.Therefore, each framework 106 carries several fuses.
Step 204, welding pin electrode.The supporting part 107 of pin electrode 105 is welded together with weld cap 102.Due to
Each framework 106 carries several fuses, therefore can realize multi-point welding technique, simultaneously multiple in lead frame 106
Fuse, it is achieved multi-point welding, rapid shaping pin electrode.Butt-joint technique can be used to weld.
Step 205, plastic shell.Plastic packaging pressure is carried out in the framework 106 welding pin electrode 105 is put into plastic sealed mould
Film, with shell molds 104.Shell 104 can use resin material, or plastic material, makes the shape such as square being easy to attachment,
It is common sense in the field.After shell molds 104, pin electrode 105 is partially exposed at outside shell 104, in order to attachment.
Step 206, Trim Molding.The monoblock framework 106 of forming shell 104 is put into bar shear rib cutting and is separated into list
Individual wire resistor product.In this step, pin electrode 105 cuts off separation from framework 106.Due to pin electrode 105 and weldering
The solder joint of cap 102 is by shell 104 plastic packaging, and therefore the cut-out of this step does not interferes with the stability of solder joint.
Certainly, after the single wire resistor of molding, also it can be electroplated, then detect, pack shipment.
Pin electrode is arranged on the traditional wire resistor structure in the middle part of weld cap by present invention change, and is moved on to by pin electrode
Bottom weld cap, more utilize general frame to weld metal pins, in batches welding pin, it is achieved automatic welding, reduce traditional structure
The single pin welding of technique and the pin of single resistance flatten technique, production efficiency is greatly improved, it is to avoid during flattening
The impact of butt welding point, also improves finished product yields.
Certainly, this invention can also have other to convert, it is not limited to above-mentioned embodiment, those skilled in the art are had
Standby knowledge, it is also possible to various changes can be made without departing from the inventive concept of the premise, such change all should fall at this
In bright protection domain.
