Detailed Embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] A heat dissipation structure of a terminal, as Figure 1 - Figure 2 shown, includes a sheet-shaped connection terminal 3 and a first terminal 1 and a second terminal 2 respectively connected to both ends of the connection terminal 3;

[0025] The connecting terminal 3 has a first surface 31 and a second surface 32 facing away from each other. A heat dissipation protrusion 4 is provided on the first surface 31, and a thermal conductive silicone 5 is provided on the second surface 32.

[0026] In power transmission, terminals are often provided at the ends of cables to connect with other cable electrical appliances. During power transmission, the heat generated by external influences and its own operation will accelerate the temperature rise, which will increase the resistance of the terminals and thus affect the power transmission efficiency and the safety of the electrical environment. The first terminal 1 and the second terminal 2 of the present application are used to connect with other cables or electrical appliances, and the connecting terminal 3 is used to connect the first terminal 1 and the second terminal 2. A heat dissipation protrusion 4 is provided on the first surface 31 of the connecting terminal 3. The heat dissipation protrusion 4 can increase the contact area between the connecting terminal 3 and the air. A thermal conductive silicone 5 is provided on the second surface 32. The thermal conductive silicone 5 can quickly absorb the heat of the connecting terminal 3 and dissipate it into the air, so as to effectively dissipate the heat of the entire terminal to ensure the transmission of large-current electric energy.

[0027] In some embodiments, the first terminal 1 and the second terminal 2 are respectively vertically connected to the first surface 31 and / or the second surface 32. The vertical connection to the first surface 31 or the second surface 32 can reduce the overall length of the terminal and is suitable for installation in more installation environments.

[0028] In some embodiments, at least one of the first terminal 1 and the second terminal 2 is a barrel-shaped terminal. The barrel-shaped terminal is convenient for plugging with a column-shaped terminal and can achieve rapid installation or replacement.

[0029] In some embodiments, at least one of the first terminal 1 and the second terminal 2 is a column-shaped terminal. The column-shaped terminal is convenient for plugging with a barrel-shaped terminal and can achieve rapid installation or replacement.

[0030] In some embodiments, the extending direction of the first terminal 1 is parallel to the extending direction of the second terminal 2. This can ensure that the original line direction does not change.

[0031] In some embodiments, there are a plurality of the heat dissipation protrusions 4 which are uniformly arranged on the first surface 31. The uniformly arranged heat dissipation protrusions 4 can better dissipate heat and make the temperature of each part of the terminal more uniform.

[0032] In some embodiments, the extending directions of the plurality of heat dissipation protrusions 4 are parallel. The parallel arrangement facilitates the generation of air convection. When the terminal is arranged in various devices, such as in a connector, the heat dissipation protrusions 4 are arranged along the heat dissipation port direction of the connector, so that the cooling air flow can circulate faster in the heat dissipation protrusions 4 and a faster cooling speed can be obtained.

[0033] In some embodiments, the connection terminal 3 has at least one bending portion 33, as Figure 2 shown. The bending portion 33 can avoid other devices in the installation environment, facilitating installation.

[0034] The present application also provides an adapter, as Figure 3 and Figure 4 shown, for respectively plugging into an automotive charging socket and a charging gun. Two terminals with a heat dissipation structure as described above are provided in the adapter. The two first terminals 1 are respectively used for plugging into the first positive terminal 6 and the first negative terminal 7 of the automotive charging socket, and the two second terminals 2 are respectively used for plugging into the second positive terminal 8 and the second negative terminal 9 of the charging gun. The adapter is used to connect the charging socket and the charging gun and adjust the conversion voltage between the charging socket and the charging gun. During the process of transmitting a lot of large current, the terminals will quickly heat up, and the present application can quickly reduce the temperature of the terminals in the adapter.

[0035] In some embodiments, the two connection terminals 3 are staggeredly arranged in the adapter, and the second surfaces 32 of the two connection terminals 3 are oppositely arranged and have a preset distance, as Figure 4 shown. The opposite arrangement of the two second surfaces 32 can enable the thermal conductive silicone 5 to obtain a larger heat dissipation space, and the heat dissipation is more sufficient.

[0036] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom are still within the protection scope of the present invention.
