Work.
As shown in Figs. 1-2, in one embodiment according to the present utility model, connector 1 is used to connect 2 He of supply module
Electronics heating tube 3.Connector 1 includes male connector 11 and female 12, and supply module 2 and fixed thereto is stretched into one end of wherein male connector 11
Connection, one end of female 12 are stretched into electronics heating tube 3, the other end of male connector 11 and the other end adaptation connection of female 12, with
Realize that supply module 2 is connected with the quick of electronics heating tube 3.During adaptation connection, directly female 12 is inserted to male connector 11, male connector 11
Can by female 12 up and down shrapnel formed elliptical openings jack up become round opening, after grafting, in female 12 above and below shrapnel
Elliptical openings state is returned to again, so that male connector 11 be clamped, is realized male connector 11 and is connected with the quick of female 12.Discharging
During connection, by pressing the button 13 in female 12, the elliptical openings that shrapnel is formed up and down in female 12 are made to become round again
Opening, so as to which male connector 11 is extracted from female 12.
However, when supply module 2 is connected by connector 1 with electronics heating tube 3, female 12 is towards the end of supply module 2
There is airspace between portion and supply module 2, causes a part for male connector 11 to be externally exposed in environment.In addition, female 12
On button 13 also have the air gap with female 12 around it.This airspace and the air gap exists connector 1 at two
The insulation in the region is unfavorable.

Connected to the end of supply module 2.It will be appreciated by those skilled in the art that the heat insulating mattress is not necessarily limited to be arranged on 12 court of female
To on the end face of supply module 2, with female 12 can also be arranged on towards at the other positions of the end of supply module 2.Separately
Outside, which can be preferably fixed to realize with some insertion female 12 towards the end face of supply module 2.
For the air gap around the button of female 12, the circle insulation ring 5 of increase by one, the insulation ring 5 is using flexible heat-insulated
Material, to lift heat insulation effect.The insulation ring 5 is enclosed in 13 surrounding of button, and fills the air gap of 13 surrounding of button, so that
The heat insulation effect of connector 1 can be effectively improved.The flexible insulant material can also use above-mentioned rubber-plastic sponge heat-insulating material, put down
When equal temperature is 0 degree Celsius, material thermal conductivity is less than 0.036W/ (m2*K).During installation, button 13 is pulled down first, and leads to
Insulation ring 5 is bonded in the surrounding of button 13 by the mode for crossing bonding, and then the button 13 for being bonded with insulation ring 5 is freezed,
Make its volume-diminished, then button 13 is installed in female 12, after recovering room temperature, button 13 is interference fitted with female 12.
By the above-mentioned end set heat insulating mattress 4 in female 12 towards supply module 2, and around the button 13 of female 12
Insulation ring 5 is set, can be effectively improved and the intermediate region that module 2 and electronics heating tube 3 cover is not supplied on connector 1
Heat insulation effect.The energy provided needed for heater on supply module 2 and electronics heating tube 3 can be so provided.Also, supply
Thermal transfer construction between module 2 and connector 1 can be also simplified.
Certainly, it will be appreciated by those skilled in the art that connector according to the present utility model 1 can only be arranged close to supply
The heat insulating mattress 4 of the end of module 2, or the insulation ring 5 around the button 13 of female 12 is only set, so as to fulfill above-mentioned effect
Fruit.
By thawing, test finds that, compared to existing connector, the connector of the utility model is in -40 degrees Celsius of environment
At a temperature of its heat insulation effect can improve 10 degrees Celsius.
