Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The embodiment 1 of connector of the invention, as shown in Figure 1 to Figure 2, the connector include housing unit 1, housing unit
1 includes insulator 4, and contact installation cavity 41 is equipped in insulator 4, installs in contact installation cavity 41 and is fixed with contact 2,
In the present embodiment, which is rectangular connector, the contact installation cavity 41 on insulator 4 have it is multiple, along insulator 4
Length direction arranged for interval, certainly, in other embodiments, the connector can be Square Connector or cylindrical connector,
Form is not specifically limited, and those skilled in the art can select specific connector form according to the actual needs.
Contact 2 in the rectangular connector is the prior art, and specific structure and the assembly between insulator 4 are closed
System is no longer described in detail, and metal heat-conducting layer 3 is fixed on the outer peripheral surface of insulator 4, the metal heat-conducting layer 3 and insulator 4 it
Between be fixedly connected by insert structure, meanwhile, in order to reduce the temperature rise of contact 2, on insulator 4 be equipped with connection contact peace
It behave affectedly the insulator heat release hole 42 of 41 and 4 outer peripheral surface of insulator, while being provided with heat-conducting layer heat release hole on metal heat-conducting layer 3
31, heat-conducting layer heat release hole 31 is connected to insulator heat release hole 42 and forms the heat dissipation channel that heating load distributes, and design can be in this way
It realizes contact 2 because the heat that temperature rise generates is dispersed into the external world from heat dissipation channel, to reduce the temperature rise for releasing part.
Meanwhile in order to guarantee heat dissipation effect, the aperture edge of heat-conducting layer heat release hole 31 has to be dissipated for being blocked in insulator
Heat conducting part 32 in the pore diameter range of hot hole 42, the setting of heat conducting part 32 can be realized heat is logical by heat dissipation
On the basis of road freely distributes, additionally it is possible to heat transfer is carried out by 3 pairs of heat of metal heat-conducting layer, it will using the high-termal conductivity of metal
Heat carries out heat loss through conduction, is acted on by the dual composite radiating of heat dissipation channel and the heat conducting part 32 of metal heat-conducting layer 3 real
Now to the inhibition of 2 temperature rise of contact, so that 2 temperature rise of contact reduces, the heat dissipation of connector is faster.
In the present embodiment, insulator heat release hole 42 is with heat-conducting layer heat release hole 31 along the axially staggered of contact installation cavity 41
Arrangement, and in the aperture edge of heat-conducting layer heat release hole 31 along the axial two sides of contact installation cavity 41 side constitute it is above-mentioned
Heat conducting part 32, the setting that heat passes to portion enable to the heat distributed when 2 temperature rise of contact that can directly lead with metal
Thermosphere 3 contacts, so that heat distributes faster, effect is more preferable.
There are two the heat dissipation channels of the same contact installation cavity 41 of above-mentioned correspondence, and two heat dissipation channels are in insulator 4
Opposite two sides it is positioned opposite, and in order to further expand contact 2 and extraneous contact area, in the present embodiment, often
Insulator heat release hole 42 in one heat dissipation channel all has two, and above-mentioned heat-conducting layer heat release hole 31 is long pore structure, meanwhile,
Two heat release holes are connected to the same heat-conducting layer heat release hole 31, can either increase contact 2 and extraneous contact area in this way,
It can guarantee heat conduction efficiency of the metal heat-conducting layer 3 to the heat given out.
In order to guarantee that metal heat-conducting layer 3 conducts the high efficiency of heat, in the present embodiment, metal heat-conducting layer 3 is led for height
The contact resistance of electric rate material, the metal heat-conducting layer 3 of high conductivity material is smaller, therefore heat-conducting effect is more preferably.
It in the actual working process, can be real by the setting of heat dissipation channel and the heat conducting part 32 of metal heat-conducting layer 3
Dual composite radiating now is carried out to the heat that 2 temperature rise of contact distributes, and then accelerates connector internal heat dissipating, reduces contact 2
Temperature rise.
The embodiment 2 of connector of the invention, difference from example 1 is that, as shown in figure 3, above-mentioned metal
Heat-conducting layer 3 can be sticked on the inner wall for being fixed on insulator 4, also can be realized the heat generated to 2 temperature rise of contact in this way
Effectively control.
The embodiment 3 of connector of the invention, difference from example 1 is that, as shown in figure 4, the same heat dissipation
Metal heat-conducting layer 3 in channel can there are two, corresponding insulator heat release hole 42 has one, and two heat-conducting layer heat release holes 31
It is connected to the same insulator heat release hole 42, thus realize distributing for heat, meanwhile, the company between two heat-conducting layer heat release holes 31
Socket part can also form heat conducting part 32.
In other embodiments, heat conducting part 32 can be by pacifying in the aperture edge of heat-conducting layer heat release hole 31 along contact
The 41 axially extending two side portions of behaveing affectedly are formed, and any portion in the aperture edge of heat-conducting layer heat release hole 31 also can be set
Divide and formed, heat-conducting layer heat release hole 31 can also be designed as anisotropic hole, there is the pore diameter range for being blocked in insulator heat release hole 42
Within conducting part.
Shell in any embodiment of the embodiment of housing unit according to the present invention, structure and above-mentioned connector
The structure of body component is consistent, is no longer developed in details.
