Specific implementation mode
To keep the above objects, features and advantages of the present invention more obvious and easy to understand, below in conjunction with the accompanying drawings and specific embodiment party
The present invention is described in further detail for formula.
As shown in Figure 1, a kind of spacecraft provided in an embodiment of the present invention power-supply controller of electric power flow concentration device, including the
One circuit for power conversion plate 11, the second circuit for power conversion plate 12, fastening assembly 3, the positive interface 4 of input power, output power are just
Interface 5, power bear interface 6 and short-term weld assembly 7.
As shown in Fig. 2, another kind spacecraft power-supply controller of electric power flow concentration device provided in an embodiment of the present invention, including
The positive interface 4 of first circuit for power conversion plate 11, copper component 2, fastening assembly 3, input power, the positive interface 5 of output power, power are negative
Interface 6 and transition copper component 8.
Composition and the basic size design of the power flow concentration device of the embodiment of the present invention are as follows：
On the basis of the input of clear power-supply controller of electric whole system, output, in conjunction with system power size and power transmission
Situation determines the composition and basic size of power flow concentration device, i.e., in addition to fastening assembly 3, the positive interface 4 of input power, output work
The positive interface 5 of rate, power bear whether need short-term weld assembly 7, transition steel structure 8 and copper component 2 outside interface 6.Meanwhile according to electricity
Stream size, drop volume situation determine the minimum sectional area of bus structure.In Spacecraft guidance and control, which uses fine copper material
Expect, minimum sectional area size should be greater than in transmission path：Electric current (A)/5 (A/mm2).
The method of fixed short-term weld assembly 7 can be as follows：
As shown in Figure 1, during power transfer, it is limited to the paving copper face product of the first circuit for power conversion plate 11 so that
Partial Power can not be passed to the positive interface 4 of input power, defeated in the case where meeting drop volume by the first circuit for power conversion plate 11
Go out the positive interface 5 of power and power bears interface 6.Therefore, from 11 other positions of the first circuit for power conversion plate by a small amount of cable
Be solded into short-term weld assembly 7, then with fastening assembly 3 by the structure and the positive interface 4 of input power, the positive interface 5 of output power and
Power is born interface 6 and is connected.7 one end of short-term weld assembly by the positive interface of through-hole and the positive interface 4 of input power, output power 5 with
And power is born interface 6 and is connected, the other end designs for welding hole, and the diameter of each welding hole is bigger 0.3mm than corresponding every cable size.It is short
Wire bonding connected components 7 also use pure copper material, but in view of that must be welded, to prevent tin from should use table with the contact corrosion of gold
Face silver-plated mode reduces impedance.
The use of the short-term weld assembly 7 can avoid caused by the same current potential in printed board is spot welded more power conductors
Share pad problem.
Following methods may be used in fixed 2 and second circuit for power conversion plate 12 of copper component：
As shown in Figure 2, it is contemplated that the sequence and detachability of installation, it must be by copper component 2 and the second circuit for power conversion plate
12 connections are integral, and this is integrally attached in power-supply controller of electric structure.Meanwhile consider with the positive interface 4 of input power,
The positive interface 5 of output power and power bear the connection of interface 6, and copper component 2 is connect one end with the second circuit for power conversion plate 12
Be designed to through-hole, the other end is the structure type of threaded hole, in order to reduce the impedance between bus structure, must to copper component 2 into
The processing of row surface gold-plating.Through-hole one end is fixed in using fastening assembly 3 on the second circuit for power conversion plate 12, and position is pressed
The location determination after interface 6 is spirally connected is born with the positive interface 4 of input power, the positive interface 5 of output power and power, by adjusting through-hole
Its installation site of tolerance values can be finely tuned accordingly, to reduce the possibility for filling and unmatching caused by accumulated error；Threaded hole one end
Using fastening assembly 3 and the positive interface 4 of input power, the positive interface 5 of output power and power interface 6 is born to be spirally connected, with reduce due to
Other circuit boards are difficult to install caused by blocking.
The method of fixed transition copper component 8：
As shown in Figures 2 and 3, in power transmittance path, if copper component 2 can not be with the positive interface 4 of input power, output work
When the positive interface 5 of rate and power are born interface 6 and is directly connected to, generally use transition copper component 8 is attached.Such case is mainly sent out
It is raw to there are 2 circuit for power conversion plates and the feelings between the two for having 1 capacitance battle array plate of power transfer or 1 power change-over panel band
Under condition.Consider it and bears the peace of interface 6 with the copper component 2 and positive interface 4 of input power, the positive interface 5 of output power and power
Situation is filled, the mounting hole of transition copper component 8 is both designed as through-hole, so that it during the installation process can be in copper component 2 and input
The positive interface 4 of power, the positive interface 5 of output power and power borrow between bearing interface 6, the operability of installation are realized, in order to subtract
Impedance between small bus structure must carry out surface gold-plating processing to transition copper component.
The method of whole sealing can be as follows：
Device debugging is completed, after sizing, and one pack system silica gel, epoxy or locking glue sealing are used on fastening assembly 3.
Power flow concentration device disclosed by the embodiments of the present invention for improving spacecraft power-supply controller of electric power-mass ratio,
Medium using the steel structure of surface gold-plating as power flow concentration, passes through the power input with different structure form, conversion, output
The power flow concentration path of entire power-supply controller of electric is established in the connection of interface, realizes the power conversion and output of power-supply controller of electric.It should
The modes such as design is by being spirally connected, short-term welds realize the reliable installation of structure, repeated removal, reduce Denso difficulty and centre
