Fig. 2 is the stereogram according to the preferred embodiment of cylinder manifold device of the present utility model; Fig. 3 is the decomposition diagram of the preferred embodiment of cylinder manifold device of the present utility model shown in Figure 2.

Referring to Fig. 2 and Fig. 3, cylinder manifold device 300 comprises upper shell 310, lower house 320 and four T shapes of combination toward each other conductor 330～360 (seeing also Figure 4 and 5 in addition) that confluxes.These four T shapes conflux conductor 330～360 be contained in by upper shell 310 and lower house 320 in conjunction with and in the enclosure interior space that constitutes, and only exposed each terminal of the conductor 330～360 that respectively confluxes in the outside of cylinder manifold device 300, the end terminal 332～362 and 334～364 that has wherein exposed the conductor 330～360 that confluxes at the two ends of cylinder manifold device 300 1 sides has respectively exposed the middle part terminal 333～363 of the conductor 330～360 that confluxes at the middle part of cylinder manifold device 300 opposite sides.

Be that example comes each T shape to this cylinder manifold device 300 conductor 330～360 that confluxes to describe with the T shape conductor 330 that confluxes below.

As shown in Figure 4, the T shape conductor 330 that confluxes is tabular generally, and comprise tabular main part 331, in the end terminal 332 at main part 331 two ends and 334 and the middle part terminal 333 that is positioned at main part 331 middle

parts.End terminal

332 and 334 be arranged on main part 331 the same side and with the length direction vertical extent of main part 331, and middle part terminal 333 is arranged on the opposite side of main part 331 and also length direction vertical extent with it.But each terminal 332～334 might not with main part 331 on same plane.For the conductor that confluxes a plurality of T shapes pile up each other after with the respective terminal of other conductor 340～360 that confluxes on same plane, slightly bend in the coupling part of terminal 332～334 with main part 331, for example in Fig. 4, for the T shape conductor 330 that confluxes, terminal 332～334 bending that all makes progress in coupling part separately, and still keep flat shape in the other parts except that these coupling parts.

Covered by the insulating material 335 that the heat shrinkage insulation pipe constitutes in the main part between

terminal

332 and 333 and between

terminal

333 and 334 331, this heat shrinkage insulation pipe can suppress the wrinkle that thermal contraction produces.Except that the thermal contraction insulated tube, this insulating material can also be the insulation filler of insulating tape, loop-like epoxy resins etc.

All provide a connecting through hole 336 respectively at the conflux middle part of each terminal 332～334 of conductor 330 of T shape, this connecting through hole 336 is used for being connected with for example external device (ED) such as power converter, load, and this connecting through hole 336 can be a suitable shape such as circular, oval, square.

In addition, be formed with a fixing hole 339 at the

conflux end terminal

332 and 334 of conductor 330 of T shape near its coupling parts, this fixing hole 339 is used for the projection that provides on the surface of lower house 320 (will be below in conjunction with lower house 320 detailed descriptions to this) thereby matches and fix this T shape conductor 330 that confluxes.This fixing hole 339 for example is circular, also can be for square, oval, triangle etc.

Other the T shape conductor 340～360 that confluxes has and the T shape similar structure of conductor 330 of confluxing, therefore explanation no longer one by one, but compare with the T shape conductor 330 that confluxes, their end terminal and middle part terminal on the length direction of main part the position and the overbending direction of coupling part is different with bending degree separately, thereby conflux after conductor piles up each other these T shapes, each end terminal and middle part terminal are staggering each other on the stacking direction and are being positioned at (referring to Fig. 3 and Fig. 5) on the corresponding plane.
