413 and connection passageway 414 formed fluid course 401 when also by contact produce heat take away, the contact element that achieves a butt joint it is cold
But.
Conductive contact piece 4 also includes adapter 3, and adapter 3 is the tubular structure with inner passage, and its one end has outer
Screw thread, uses for the screw-internal thread fit with inlet 421 and liquid outlet 422, and the other end of adapter 3 has conehead, so as to
Convenient docking when being connected with inlet tube 1 and outlet 2.
Connector of the invention is in use：
Conductive contact piece is screwed on inlet 421 and liquid outlet 422 two adapters 3 in assembling respectively, due to what is coordinated
Screw thread is the screw thread of elastically deformable, is connected through a screw thread and sealing is capable of achieving after screwing, anti-silicone oil leakage；Inlet tube 1 and outlet
After pipe 2 is inserted on the conehead of adapter 3, by welding manner fixation；When pressure connection terminal is assembled with contact pin end 41, will press
Connect in the shoulder hole at the insertion contact pin of catch 423 end 41 at end 42, rotation pressure connection terminal 42 or contact pin end 41 equal both positioning
Face correctly aligns, to ensure that catch 423 is on the symmetrical plane of inlet 421 and liquid outlet 422, then by the He of pressure connection terminal 42
Contact pin end 41 is welded and fixed.
When using, the insulating and cooling liquid in tank for coolant（Such as silicone oil）Into inlet tube 1, then through inlet 421 at
Adapter 3 enters feed liquor runner 412 through inlet 421 again, then enters liquid runner 413 by connection passageway 414, most passes through afterwards
Liquid outlet 422, adapter 3 and outlet 2 are flowed back in tank for coolant, in coolant during the entire process of contact is flowed through
A part of heat that contact is produced is taken out of, the cooling of the contact element that achieves a butt joint.
In other embodiments：Silicone oil also can be replaced other has the liquid medium of insulating properties；Fluid course also may be used
Only include one connection inlet and liquid outlet interface channel, i.e., back-turning section is no longer set, now coolant because with contact
Contact area diminish, it is therefore good not as setting back-turning section to the cooling effect of contact；At adapter and inlet and liquid outlet
Connection can be also attached using directly welding or using crimping mode, using crimping, such as bolt crimping mode when, it is necessary to
Sealing structure is set, in case silicone oil is revealed；Two adapters can also one using sealing threaded connection, another is using welding
Or crimping mode is connected；The mode that catch is integrally fixedly connected with pressure connection terminal also can be replaced and catch be not provided with pressure connection terminal, and
It is that catch is individually welded in the shoulder hole at contact pin end, is welded by end during welding；Shoulder hole inside contact pin end also may be used
Cylinder straight hole is replaced with, that is, is not provided with step, correspondingly catch is without setting narrow section and section wide, but this structure may be for
It is more suitable when contact is larger.
The embodiment of self-cooled conductive contact piece of the invention connects with the conduction in each embodiment of connector of the invention
Each embodiment of contact element is identical, repeats no more.
