Describe the power interface 100 according to this utility model embodiment referring to Fig. 1-Figure 10 in detail.It is worth understanding
It is described below to be merely illustrative, rather than to concrete restriction of the present utility model.
For convenience of describing, so that power interface 100 is as Type-C as a example.Type-C interface full name is USB Type-C interface,
It is a kind of interface shape, is that USB standard has been organized as solution USB interface physical interface specification disunity for a long time, electricity
Can the drawback such as one-way transmission and formulate brand-new data, video, audio frequency, electric energy coffret specification.
The feature of Type-C is：The equipment of standard can be by the CC pin in interface specification come another to connect
Side declares oneself to take the wish (i.e. the anode connecting line of traditional USB) of VBUS, and a side of stronger wish finally exports to VBUS
Voltage and current, the opposing party then accepts the power supply of VBUS bus, or still refusal accepts power supply, but does not affect transfer function.
In order to more easily using this bus definition.Type-C interface chip (such as LDR6013), is typically divided into four equipment
Plant role：DFP、Strong DRP、DRP、UFP.The wish that these four roles take VBUS bus is successively decreased successively.
Wherein, DFP is equivalent to adapter, can persistently want to VBUS output voltage, and Strong DRP is equivalent to mobile electricity
Source, only when meeting adapter, just abandons exporting VBUS.DRP is equivalent to mobile phone, under normal circumstances, all expects other side to certainly
Oneself powers, but when meeting the equipment also weaker than oneself, then that also undertakes to do what is apparently beyond one's ability exports to other side, and UFP is externally not export electricity
Can, generally light current pool equipment, or no battery apparatus, such as bluetooth earphone.USB Type-C supports positive anti-plug, due to just
Anti- two sides has altogether four groups of power supplys and ground, can significantly be lifted on power is supported again.
Power interface 100 in the present embodiment can be USB Type-C interface, and it goes for quick charge
The power supply adaptor of function, is also applied for common power adapter.Here, it should be noted that quick charge can refer to charge
Electric current is more than the charged state of 2.5A or rated output power is not less than the charged state of 15W；Common charging can refer to charge
Electric current is less than or equal to the charged state of 2.5A or rated output power is less than the charged state of 15W.That is, when using tool
When the power supply adaptor having quick-charge function charges to power interface 100, charging current is more than or equal to 2.5A or specified defeated
Go out power and be not less than 15W；When being charged to power interface 100 using common power adapter, charging current be less than 2.5A or
Rated output power is less than 15W.
In order that the power supply adaptor standardization that power interface 100 is adapted with power interface 100, need to make power supply connect
The size of mouth 100 meets the design requirement of standard interface.For example, pin foot 121 number is 24 power interface 100, and its design will
The width (width on the left and right directions of power interface 100, as shown in Figure 1 left and right directions) asked is a, in order that the present embodiment
In power interface 100 meet design standard, the width (right and left of power interface 100 of the power interface 100 in the present embodiment
Width upwards, left and right directions as shown in Figure 1) also it is a.For enabling power supply pin foot 121a to carry in limited space
Part pin foot 121 in 24 pin feet 121 can be saved by larger charging current, increases power supply pin foot 121a's simultaneously
Cross-sectional area is used for carrying larger charging current, and what power supply pin foot 121a increased partly can be arranged in the pin foot being omitted
At 121 position, on the one hand achieve the optimization layout of the part to power interface 100, on the other hand increase power supply pin foot
130 can hold current-carrying ability.
Specifically, as Figure 1-Figure 8, power interface 100 includes：Insertion shell 110 and grafting main body 120.Wherein, insert
Connect main body 120 to include：First encapsulated portion 130, the second encapsulated portion 150 and 14 pin feet 121.First encapsulated portion 130 and the second bag
Glue portion 150 can adopt the material of good heat dissipation effect to make, for example, polyamide (such as stanyl PA46).Polyamide resin
Fat has the property that：
| Thermal properties | dry/cond | ||
| Thermal conductivity in plane | 2.1 | W/(mK) | ASTM E1461 |
| Thermal conductivity through plane | 0.9 | W/(mK) | ASTM E1461 |
It should be noted that by arranging two encapsulated portions in grafting main body 120, grafting main body 120 can be made to have
Different performances, for example, the first encapsulated portion 130 and the second encapsulated portion 150 can be fabricated by, by making using different materials
Grafting main body 120 can be made to meet different strength demands with different materials, alternatively, it is also possible to by from different materials
