Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1 and Fig. 2, a kind of backboard jockey being applicable to direct current power allocation units, comprise backboard 2, backboard 2 is provided with at least two female female inserted terminal subgroups, female female inserted terminal subgroup comprises positive female female inserting terminal and negative power female female inserting terminal, and positive female female inserting terminal and negative power female female inserting terminal are respectively equipped with some backboard positive power terminal 4 for connection mode blocking direct current power allocation units 1 and backboard negative power terminal 5;
Described backboard 2 is also provided with the electrical system negative power terminal 7 that at least two are used for the negative power line of electrical system power source to cause for the electrical system positive power terminal 6 and at least two the positive line of electrical system power source module being caused positive female female inserting terminal negative power female female inserting terminal; Described electrical system positive power terminal 6 and electrical system negative power terminal 7 are blade inserting terminal, backboard 2 is also provided with the signal terminal 8 for realizing electrical system and modularized dc power distributing unit 1 information interaction, described signal terminal 8 is male type socket;
Be positioned at same horizontally-arranged backboard positive power terminal 4 to be connected with corresponding electrical system positive power terminal 6 by positive line, be positioned at same horizontally-arranged backboard negative power terminal 5 to be connected with corresponding electrical system negative power terminal 7 by negative power line, described backboard 2 is six layers of PCB (PrintedCircuitBoard, printed circuit board) backboard, positive line is located at the second layer and the third layer of six layers of PCB backboard; Negative power line is located at the 4th layer and layer 5 of six layers of PCB backboard, and vice versa.
When deployed, backboard 2 is connected with the system interpolation frame 3 that female female inserting terminal component can be separated, each female female inserted terminal subgroup is connected with a modularized dc power distributing unit 1, and the positive female female inserting terminal of each female female inserted terminal subgroup is connected to the positive plate of modularized dc power distributing unit 1 by backboard positive power terminal 4; The negative power female female inserting terminal of each female female inserted terminal subgroup is connected to the negative power plate of modularized dc power distributing unit 1 by backboard negative power terminal 5.
Below operating process of the present utility model is described in detail:
With 10 power modules in accompanying drawing 2, i.e. 10 positive lines and 10 negative power lines, 5 modularized dc power distributing unit are example, describe execution mode of the present utility model in detail.
In figure, J1A, J2A are respectively positive female female inserting terminal and the negative power female female inserting terminal of 1# female female inserted terminal subgroup, by that analogy, J9A, J10A are respectively positive female female inserting terminal and the negative power female female inserting terminal of 5# female female inserted terminal subgroup.Wherein, J1A, J3A, J5A, J7A, these 5 positive female female inserting terminals of J9A, top-down 10 the backboard positive power terminal 4 of each positive female female inserting terminal, 10 electrical system positive power terminal Vin1+ to Vin10+ of electrical system are connected respectively by positive line, and J2A, J4A, J6A, J8A, these 5 negative power female female inserting terminals of J10A, top-down 10 the backboard negative power terminals 5 of each negative power female female inserting terminal, 10 electrical system negative power terminal Vin1-to Vin10-of electrical system are connected to respectively by negative power line.As in figure two connect line illustrated, walk positive line by the layers 2 and 3 in 6 layers of PCB backboard, and walk negative power line by the 4th layer and the 5th layer, do not walk power line for the 1st layer and the 6th layer.
In order to realize such scheme, in the utility model, on backboard 2 each positive power terminal each stitch between distance, depend on the use protection distance of electric safety Distance geometry reality, such as prevent dust, creepage etc.In addition, due in system use, direct current power allocation units need wind-cooling heat dissipating, need the guide groove opening a large amount of enough width on backboard to ventilate.Therefore, the copper sheet that 4 internal layers in fact on backboard walk power line has above-mentioned two constraints.Determine in each power stitch distance, under the prerequisite that groove width is determined, four actual maximum currents that can bear of internal layer are determined.
But consider suitably to relax above-mentioned two constraintss, four actual maximum currents that can bear of internal layer can have certain flexibility ratio.
This 4 internal layers walk power line, and power line is not walked on 2 top layers, and tool has the following advantages: one is a simplified back board structure, avoid using busbar and the welding procedure problem brought and electric safety problem; Two are that of avoiding the integrity problem that humidity, salt fog etc. bring for the corrosion of PCB itself.
