Background

With the increasing demand for fast charging and the demand for miniaturization and portability of power adapters for consumers of electronic products, the power adapters implement technical innovation of high frequency and high power, but also bring about the problem of heat dissipation of high-density heat source devices with small sizes. The shell material of the power adapter is usually plastic, and the plastic has lower heat conductivity coefficient and poorer temperature equalizing capability, so that the overall heat dissipation capability of the power adapter cannot be greatly improved, and the service life of internal devices can be influenced. Therefore, a technician invents a power adapter of glue-pouring heat storage technology, namely, heat generated by the heating device during high-power short-time operation is absorbed by the heat-conducting pouring material by wholly or partially pouring heat-conducting materials in the internal device, so that the temperature of the shell of the adapter is reduced. However, the heat dissipation function of the power adapter in such a design is limited by the filling amount of the potting heat conduction material and the heat capacity of the material, and the heat dissipation purpose cannot be achieved under the condition of long high-power charging time. Therefore, it is the key and difficult point in the present technical field to solve the heat dissipation problem of the small-sized high-power adapter.

As shown in fig. 2, the pins 40 include a first pin 41 and a second pin 42. The first pin 40 includes a body 411, a slot 412 and a U-shaped pin 413, the slot 412 is symmetrically disposed on two sides of the body 411, and is a connection portion between the first pin 41 and the plastic structure, and the U-shaped pin 413 is connected to the bottom of the body 411.

The structure of the main body 421 is the same as that of the first pin 41, but this is not necessary, and the structure of the main body 421 may be designed differently from that of the first pin 41 according to practical requirements. The connecting portion 422 and the heat conducting portion 423 are made of the same material as the main body portion 421, and may be made of a copper alloy material, but this is not essential, and the connecting portion 422 and the heat conducting portion 423 may be made of a non-metal heat conducting material.

Referring back to fig. 1, the connecting portion 422 increases the total length of the second pin 42 to be greater than the length of the first pin 41, so that the heat conduction portion 423 extends into the vicinity of the heat generating device 11.

The structure of the main body 521 is the same as that of the first pins 51, but this is not necessary, and the structure design of the main body 521 can be different from that of the first pins 51 according to actual requirements. The material of the connecting portion 522 and the heat conducting portion 523 is the same as that of the main body portion 521, and is, for example, a copper alloy material, but this is not essential, and the material of the connecting portion 522 and the heat conducting portion 523 may be a non-metal heat conducting material.

And there is no direct electrical connection between the second pins 42 and the heat generating device 11 due to the insulating property of the heat conductive insulator 43. The thermally conductive insulator 43 may be an L-shaped mylar tab (shown in fig. 6). The heat-conducting insulating member 43 may also be an L-shaped hollow sleeve (as shown in fig. 7), and the heat-conducting insulating member 43 is sleeved on the second pin 42.
