Brief description of the drawings
Fig. 1 is the phantom of structure described in the utility model；
Fig. 2 is Fig. 1 schematic side view；
Fig. 3 is the schematic diagram of welding piece described in the utility model.
In figure：Resin containment vessel 1, thermal vias 1-1, groove 1-2, PN piece 2, welding piece 3, blind hole 3-1, pin 4, through hole
A4-1, through hole B4-2, projection 5.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of diode for being conveniently replaceable PN pieces, including shell, the shell is by two trees
Fat containment vessel 1 forms, and the joint places of two resin containment vessels 1 is provided with groove 1-2, by recessed between the resin containment vessel 1
Gluing is fixed in groove 1-2, and PN pieces 2, welding piece 3 and pin 4, the one side and PN of the welding piece 3 are fixed with the shell
Piece 2 connects, and another side is provided with blind hole 3-1, in one end insertion blind hole 3-1 of the pin 4 and with the company of fitting of welding piece 3
Connect, the welding piece 3 is made of an electrically conducting material, and the outer wall of pin 4 is provided with projection 5, be provided with the resin containment vessel 1 with
The groove that the size of projection 5 is mutually matched, the pin 4 are provided with through hole A4-1 and through hole B4-2, the through hole A4-1 and protected with resin
The distance of protective case 1 is 1mm-2mm, and the through hole B4-2 is located at the side of pin 4.
The welding piece 3 is identical with the making material of pin 4.
The glue uses PUR.
The flanking central of the resin containment vessel 1 is provided with seal groove, and diaphragm seal is provided with the seal groove.
The shell is provided with multiple thermal vias 1-1.
Operation principle：The PN pieces 2 of the present utility model for being mainly characterized by being conveniently replaceable inside resin containment vessel, change PN pieces
When, the glue between groove 1-2 is removed first, then resin containment vessel 1 above is removed, allows pin 4 and welding piece 3 to separate
The PN pieces 2 to break down are taken out afterwards, and the PN pieces then more renewed are easy to disassemble because welding piece 3 can slide with pin 4, more
Cover resin containment vessel 1 after changing, then by groove 1-2 gluing two resin containment vessels 1 are fixed, so diode
Do not have to newly change diode after interior PN pieces damage, can avoid making circuit board damage when changing diode, but also be avoided that replacing
The problem of pin 4 and circuit board terminals not prison welding are leaned on during diode, projection 5 avoids pin 4 from being slided out out of resin containment vessel 1
Go, through hole A is easy to allow pin bending, is preferably fixed with circuit board terminals beneficial to pin in through hole B, because welding pen solder
After thawing, tin by through hole B and circuit board contacts, can add the stationarity of pin.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
The principle of utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change
