The polyamide resin has a good heat dissipation effect, so that the heat dissipation requirement of the plug main body 120 can be met. It should be noted that the power interface 100 generates a large amount of heat during the charging process, especially during the fast charging process, and the influence of the heat accumulation on the current transmission is more obvious.

On one hand, the plug main body 120 and the plug housing 110 can be firmly and stably assembled together, and on the other hand, the plug main body 120 and the plug housing 110 are connected together by using the adhesive layer, so that the plugging strength of the power interface 100 can be improved, and the fatigue damage of the power interface 100 caused by repeated plugging operation can be delayed.
As shown in fig. 1-4, according to one embodiment of the present application, the plug body 120 further includes: and a second encapsulant portion 150. Wherein, the second encapsulating part 150 is embedded on the first encapsulating part 130, and part of the peripheral wall of the second encapsulating part 150 is configured to be inserted into the front end face 120a of the main body. It should be noted that, two rubber coating portions are arranged on the plug main body 120, so that the plug main body 120 has different performances, for example, the first rubber coating portion 130 and the second rubber coating portion 150 can be made of different materials, the plug main body 120 can meet different strength requirements by using different materials, and in addition, the plug main body 120 can meet different heat dissipation requirements by selecting different materials. Of course, the first and second adhesive coating portions 130 and 150 may also provide the plug body 120 with an aesthetic appearance.
According to one embodiment of the present application, as shown in fig. 3-4, the first adhesive wrapping portion 130 is provided with a main body embedding notch 134 and an extended embedding notch 135. Accordingly, the second encapsulating portion 150 includes a main body embedding portion 151 and an extension embedding portion 152, the main body embedding portion 151 is connected with the extension embedding portion 152, the main body embedding portion 151 is matched with the main body embedding notch 134, the extension embedding portion 152 is matched with the extension embedding notch 135, and a front end surface 152a of the extension embedding portion is configured to be inserted into the front end surface 120a of the main body. Thereby, the first and second wrapping portions 130 and 150 can be stably connected together. It can be understood that the first and second adhesive coating portions 130 and 150 wrap and connect the pins 121 to form the plug main body 120, and the pins 121, the first and second adhesive coating portions 130 and 150 can be firmly assembled together by using the main body embedding portion 151 and the main body embedding notch 134, the extension embedding portion 152 and the extension embedding notch 135, so that the structural strength and the assembling stability of the plug main body 120 can be improved.
Further, as shown in fig. 8, one of the first wrapping portion 130 and the second wrapping portion 150 is provided with an insertion protrusion 153, and the other is provided with an insertion groove 136 adapted to the insertion protrusion 153. Thereby, the connection stability and reliability of the first and second wrapping portions 130 and 150 can be further enhanced. For example, in the example shown in fig. 8, the first adhesive covering portion 130 is provided with an insertion groove 136, and the second adhesive covering portion 150 is provided with an insertion protrusion 153 adapted to the insertion groove 136.
According to an embodiment of the present application, as shown in fig. 3, an insert protrusion 153 may be provided on the extended insert portion 152. Further, as shown in fig. 8, the plurality of insertion protrusions 153 may be spaced apart, and correspondingly, the plurality of insertion grooves 136 are also provided and correspond to the plurality of insertion protrusions 153 in a one-to-one manner. Thereby, the connection stability and reliability of the first and second wrapping portions 130 and 150 can be further enhanced.
According to an embodiment of the application, the pin 121 comprises a power pin 121a and a data pin 121b, the power pin 121a having a widened section 1211, the widened section 1211 having a cross-sectional area larger than a cross-sectional area of the data pin 121b for increasing a current load of the power pin 121 a. By setting the widened section 1211 on the power pin 121a, the current load of the power pin 121a can be increased, so that the transmission speed of the current can be increased, the power interface 100 has a function of fast charging, and the charging efficiency of the battery is improved.
According to an embodiment of the present application, the widened section 1211 is provided with a recess 1212 at a position near the front end of the power pin 121 a. It should be noted that, when the power interface 100 performs fast charging, the power pin 121a with the widened section 1211 can be used to carry a larger charging current; the recess 1212 on the widened section 1211 prevents the power pin 121a from contacting the corresponding pin 121 on the power adapter when the power interface 100 is normally charging. Thus, the power interface 100 in the present embodiment can be applied to different power adapters. For example, when the power interface 100 performs fast charging, the power interface 100 may be electrically connected to a corresponding power adapter having a fast charging function; when the power interface 100 is normally charged, the power interface 100 may be electrically connected to a corresponding normal power adapter. Here, it should be noted that the rapid charging may refer to a charging state in which the charging current is 2.5A or more or a charging state in which the rated output power is not less than 15W; ordinary charging may refer to a state of charge with a charging current of less than 2.5A or a state of charge with a rated output power of less than 15W.
According to one embodiment of the present application, as shown in FIGS. 9 and 10, the widened section 1211 has a cross-sectional area S, S ≧ 0.09805mm2. Proved by experiments, when S is more than or equal to 0.09805mm2At this time, the current load amount of the power pin 121a is at least 10A, so that the charging efficiency can be improved by increasing the current load amount of the power pin 121 a. Further experiments prove that when S is 0.13125mm2In this case, the current load amount of power pin 130 is 12A or more, thereby improving the charging efficiency.
According to an embodiment of the present application, as shown in fig. 9 and 10, the thickness of power pin 121a is D, and D satisfies: d is more than or equal to 0.1mm and less than or equal to 0.3 mm. Through experimental verification, when D is larger than or equal to 0.1mm and smaller than or equal to 0.3mm, the current load capacity of the power pin 121a is at least 10A, and therefore the charging efficiency can be improved by improving the current load capacity of the power pin 121 a. Further experiments verify that when D is 0.25mm, the current load of the power pin 130 can be greatly increased, and the current load of the power pin 121a is 12A or more, so that the charging efficiency can be improved.
According to an embodiment of the present application, as shown in fig. 9 and 10, the power pin 121a has a contact surface adapted to be electrically connected to the conductive member, and the width of the contact surface in a width direction (a left-right direction shown in fig. 9 and 10) of the power pin 121a is W, where W satisfies: w is more than or equal to 0.24mm and less than or equal to 0.32 mm. Through experimental verification, when W is larger than or equal to 0.24mm and smaller than or equal to 0.32mm, the current load capacity of the power pin 121a is at least 10A, and therefore the charging efficiency can be improved by improving the current load capacity of the power pin 121 a. Further experiments verify that when W is 0.25mm, the current load of the power pin 121a can be greatly increased, and the current load of the power pin 121a is 12A or more, so that the charging efficiency can be improved.
The power interface 100 according to an embodiment of the present application is described in detail below with reference to fig. 1-10. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting.
For convenience of description, the power interface 100 is taken as Type-C as an example. The Type-C interface is called as a USB Type-C interface, is an interface form, and is a brand new data, video, audio and electric energy transmission interface specification established by a USB standardization organization for solving the defects that the USB interface is not unified in physical interface specification and only can transmit electric energy in one way for a long time.
Type-C is characterized in that: standard devices can announce their intention to occupy VBUS (i.e. positive terminal connection line of conventional USB) to the other connected party through CC pin in interface specification, and the stronger intention of the party finally outputs voltage and current to VBUS, and the other party accepts power supply of VBUS bus or refuses to accept power supply, but does not affect transmission function. In order to enable more convenient use of this bus definition. Type-C interface chips (e.g., LDR6013) generally divide a device into four roles: DFP, Strong DRP, UFP. The willingness of the VBUS bus occupied by the four roles is decreased in sequence.
Among them, DFP is equivalent to an adapter and continuously wants to output a voltage to VBUS, Strong DRP is equivalent to a portable power source, and the output of VBUS is abandoned only when the adapter is encountered. The DRP is equivalent to a mobile phone, and normally, the other party is expected to supply power to the other party, but when a device weaker than the other party is encountered, the device is just difficult to output to the other party, and the UFP does not output power to the outside, and is generally a weak battery device or a battery-free device, such as a bluetooth headset. The USB Type-C supports positive and negative insertion, and because the positive and negative surfaces are provided with four groups of power supplies and ground, the power support can be greatly improved.
In order to standardize the power interface 100 and the power adapter adapted to the power interface 100, the size of the power interface 100 needs to meet the design requirements of the standard interface. For example, in the power interface 100 having 24 pins 121, the width required for design (the width in the left-right direction of the power interface 100, as shown in fig. 1) is a, and in order for the power interface 100 in the present embodiment to satisfy the design criteria, the width of the power interface 100 in the present embodiment (the width in the left-right direction of the power interface 100, as shown in fig. 1) is also a. In order to enable the power pin 121a to carry a large charging current in a limited space, a part of the 24 pins 121 may be omitted, and meanwhile, the cross-sectional area of the power pin 121a is increased to carry a large charging current, and the increased part of the power pin 121a may be arranged at the position of the omitted pin 121, so that on one hand, the optimized layout of the components of the power interface 100 is realized, and on the other hand, the current carrying capacity of the power pin 130 is increased.
Specifically, as shown in fig. 1 to 8, the power interface 100 includes: a plug housing 110 and a plug body 120. Wherein, the insertion body 120 includes: first gel-coated portion 130, second gel-coated portion 150, and 14 pins 121. The first and second wrapping portions 130 and 150 may be made of a material having a good heat dissipation effect, for example, polyamide resin (e.g., stanyl PA 46). The polyamide resin has the following characteristics:
| Thermal properties | dry/cond | ||
| Thermal conductivity in plane | 2.1 | W/(m K) | ASTM E1461 |
| Thermal conductivity through plane | 0.9 | W/(m K) | ASTM E1461 |
it should be noted that, two rubber coating portions are arranged on the plug main body 120, so that the plug main body 120 has different performances, for example, the first rubber coating portion 130 and the second rubber coating portion 150 can be made of different materials, the plug main body 120 can meet different strength requirements by using different materials, and in addition, the plug main body 120 can meet different heat dissipation requirements by selecting different materials. Of course, the first and second adhesive coating portions 130 and 150 may also provide the plug body 120 with an aesthetic appearance.
The 14 pins 121 include six data pins 121b and eight power pins 121 a. The six data pins 121B are a5, a6, a7, B5, B6 and B7, respectively, and the eight power pins 121a are a1, a4, a9, a12, B1, B4, B9 and B12, respectively. The eight power pin pins 121a include four VBUS and four GND therein. The middle patch 122 is sandwiched between the two opposing GNDs. The rear ends of the six data pins 121b and the rear ends of the eight power pins 121a are electrically connected to the circuit board 160, respectively.
