The second mating joint 82 is formed on the outer side of the housing main body 810 and communicates with the inner cavity 803. The first mating joint 81 is used for mating connection with a pipe joint 20 on an insulating cap 2 of the power transmission member 1, and the second mating joint 82 is used for mating connection with a connecting pipe (not shown) of a cooling circuit (not shown), so that a cooling passage 10 (see Figure 17 ) in the power transmission member 1 can be connected to the cooling circuit via the fluid transfer module 8.

[0059] As Figures 1 to 11 shown, in the illustrated embodiment, two inner cavities 803 separated from each other are defined in the housing main body 810, and the housing 80 includes two first mating joints 81 respectively communicating with the two inner cavities 803. The two first mating joints 81 are used for respectively mating connection with two pipe joints 20 on an insulating cap 2 of the power transmission member 1.

[0060] As Figures 1 to 11 shown, in the illustrated embodiment, the housing 80 includes two second mating joints 82 respectively communicating with the two inner cavities 803. The two second mating joints 82 are used for respectively mating connection with two connecting pipes of the cooling circuit.

[0061] As Figures 1 to 11 shown, in the illustrated embodiment, the first mating joint 81 has a first jack 801 for inserting the pipe joint 20, the second mating joint 82 has a second jack 802 for inserting the connecting pipe, and the first jack 801 and the second jack 802 communicate with the inner cavity 803.

The screw 85 passes through the front cover 83 and is threadedly connected to the front side of the housing body 810 to fix the front cover 83 to the front side of the housing body 810. The sealing ring 86 is squeezed between the front cover 83 and the housing body 810 to achieve sealing therebetween.

[0064] As Figures 1 to 11 shown, in the illustrated embodiment, the fluid transfer module 8 further includes a locking member (not shown) which is inserted into the first pair of fittings 81 for locking the pipe joint 20 to the first pair of fittings 81. The locking member is capable of moving axially along the first pair of fittings 81 between a locking position engaged with the pipe joint 20 and an unlocking position separated from the pipe joint 20. The aforementioned locking member can adopt any suitable locking member in the prior art. Therefore, reference can be made to the locking members in the prior art. For the sake of brevity, the locking member will not be described herein.

[0065] As Figures 1 to 11 shown, in the illustrated embodiment, the fluid transfer module 8 further includes an unlocking member 84 which is mounted on the housing body 810 and is capable of moving radially along the first pair of fittings 81. An inclined surface 84b inclined axially with respect to the first pair of fittings 81 is formed on the unlocking member 84. The inclined surface 84b is used to convert the radial movement of the unlocking member 84 into an axial movement of the locking member so that the locking member can be axially pushed from the locking position to the unlocking position by the unlocking member 84.

[0066] As Figures 1 to 11 shown, in the illustrated embodiment, the unlocking member 84 is capable of moving radially along the first pair of fittings 81 between a first position ( Figure 9 the position shown) and a second position ( Figure 10 the position shown). When the unlocking member 84 is moved to the first position, the unlocking member 84 axially pushes the locking member to the unlocking position through the inclined surface 84b thereon. When the unlocking member 84 is moved to the second position, the unlocking member 84 is separated from the locking member and the locking member automatically elastically returns to the locking position.

Both sides of the unlocking member 84 are respectively inserted into the slots 82b of the pair of side plates 821 and can move along the slots 82b between a first position and a second position.

The unlocking member 84 has an elastic buckle 840 passing through the slot hole 82a. A first rib 841 and a second rib 842 located below the first rib 841 are formed on the elastic buckle 840. When the unlocking member 84 is moved to the first position, the first rib 841 abuts against the lower edge portion of the slot hole 82a to hold the unlocking member 84 in the first position. When the unlocking member 84 is moved to the second position, the second rib 842 abuts against the upper edge portion of the slot hole 82a to hold the unlocking member 84 in the second position.

[0070] As Figures 1 to 11 shown, in the illustrated embodiment, an annular clamping groove 81a is formed on the outer peripheral surface of the end of the first pair of fittings 81. The unlocking member 84 further has an arc-shaped plate 84a located above the annular clamping groove 81a. When the unlocking member 84 is moved to the first position, the arc-shaped plate 84a of the unlocking member 84 is inserted into the annular clamping groove 81a to prevent the unlocking member 84 from moving axially on the first pair of fittings 81, so that the unlocking member 84 is reliably held in the first position.

[0071] As Figures 1 to 11 shown, in the illustrated embodiment, when the unlocking member 84 is moved to a pre-installed position ( Figure 11 the position shown) between the first position and the second position, the first rib 841 abuts against the upper edge portion of the slot hole 82a to hold the unlocking member 84 in the pre-installed position. When the unlocking member 84 is in the pre-installed position, the unlocking member 84 does not interfere with the locking member and the pipe joint 20, allowing the pipe joint 20 to be inserted into the first pair of fittings 81.

[0072] As Figures 1 to 11As shown, in the illustrated embodiment, the housing 80 includes a plurality of first mating connectors 81 for respectively matingly connecting with a plurality of pipe connectors 20. The fluid transfer module 8 includes a plurality of locking members respectively installed in the plurality of first mating connectors 81. The unlocking member 84 can axially push the plurality of locking members from the locked position to the unlocked position simultaneously.

[0073] As Figures 1 to 11 shown, in the illustrated embodiment, the first mating connectors 81 and the second mating connectors 82 are the same, such that either the first mating connectors 81 or the second mating connectors 82 can not only matingly connect with the pipe connectors 20, but also matingly connect with the connecting pipes.

The insulator 13 has an intermediate partition wall 13a separating the two cooling passages 10. The two cooling passages 10 are adjacent to the first metal row 11 and the second metal row 12 respectively, so that the first metal row 11 and the second metal row 12 can be cooled by the cooling fluid flowing through the two cooling passages 10 respectively.

[0077] As Figures 1 to 19 shown, in the illustrated embodiment, the insulator 13 has a partition wall 13b separating the cooling passage 10 from the first metal row 11 and the second metal row 12, so that the cooling fluid flowing through the cooling passage 10 cannot physically contact the first metal row 11 and the second metal row 12.

[0078] As Figures 1 to 19 shown, in the illustrated embodiment, the insulator 13 is an injection molded part directly formed on the first metal row 11 and the second metal row 12 by an insert injection molding process, so that the first metal row 11, the second metal row 12 and the insulator 13 become an integral part.
