On, because the length of input, output lead is shorter, and it is metal material.When Switching Power Supply is assembled in subscriber line cards, in weldering
When connecing Switching Power Supply input, output lead, the high temperature of generation easily melts lead and the scolding tin of epoxy circuit board, it may appear that draw
Line loosens phenomenon, can drop to enclosure interior for tack lead, other electronic components are contacted with enclosure interior, cause short
Road；For bottom then the weldering in epoxy circuit board can be extracted with stepped lead with the level when with subscribers' line plate weld
Disk, cause subscriber line cards and Switching Power Supply to input, the contact of output lead it is unreliable, the use to Switching Power Supply brings safety
Hidden danger.
The content of the invention
It is an object of the invention to provide the assembly method of Switching Power Supply pin configuration and Switching Power Supply lead, to solve to open
Powered-down source is arranged in subscriber line cards, when welding Switching Power Supply input, output lead, the loosening of Switching Power Supply lead occurs
Problem.
In order to solve the above technical problems, the technical solution used in the present invention is：
A kind of Switching Power Supply pin configuration, it includes shell, is sequentially provided with aluminium base line from the bottom to top in the inner chamber of shell
Road plate, epoxy circuit board, insulation board, cover plate of outer casing, the both sides of the epoxy circuit board are provided with several first lead pad, described
The subjacent both sides of epoxy circuit board are respectively equipped with welding lead wiring board, the welding lead wiring board be provided with it is described
Position the second lead pad of corresponding number identical of first lead pad, stepped lead is welded on second lead pad
In after insertion first lead pad, the stepped lead is described outer with being extended upward after first lead pad welding
Shell.
As a further improvement on the present invention, the epoxy line that the length of the welding lead wiring board is close to it
The length of side of road plate is consistent.
As the further improvement of the present invention, the stepped portions of the stepped lead are arranged on the welding lead circuit
Between plate and the epoxy circuit board.
The assembly method of above-mentioned Switching Power Supply lead, it comprises the following steps：
Step 1: will be inserted with stepped lead in each corresponding second lead pad, the stepped lead
It is close to the surface of the welding lead wiring board in stepped portions bottom surface；
Step 2: the good stepped lead of the welding lead wiring board and grafting is overturn into 180 °, by the stepped lead
Top be positioned over horizontal plane, each stepped lead is welded successively in the bottom surface of the welding lead wiring board；
Step 3: the stepped lead after welding is inserted in the epoxy circuit board each corresponding described first
In lead pad, the stepped portions top surface of the stepped lead is close to the bottom surface of the epoxy circuit board, in the epoxy circuit
The surface of plate is welded successively to the stepped lead, completes being welded and fixed for the stepped lead.
Stepped lead is first welded on welding lead wiring board by the present invention, is then again welded it with epoxy circuit board
Connect, blocked stepped lead using two wiring boards, prevent it from moving up and down, reach the purpose of anchor leg, in switch electricity
Even if scolding tin when source and subscriber line cards erection welding between stepped lead and the first lead pad melts, the platform of stepped lead
Rank position is stuck between epoxy circuit board and welding lead wiring board, and stepped lead will not also be pulled out from the first lead pad
Go out, also do not fall out into shell inner cavity.The lead that the present invention is assembled is fixed, is difficult to come off from lead pad, enhancing
The reliability that is connected between Switching Power Supply and subscriber line cards.Simple in construction, install convenient of the invention, it is safe and reliable.
