[0025] The embodiments described below are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0026] Refer to Figures 1 to 5 , this embodiment provides a highly efficient heat dissipating connector, which includes a connector body 100 made of heat-conducting plastic, an outer terminal 200, an inner terminal 300, a heat conducting sheet 400 and a heat dissipation component. One end of the connector body 100 is open and extends towards the opposite end to form an accommodating cavity 110. The outer terminal 200 is arranged in the accommodating cavity 110, the inner terminal 300 is arranged in the outer terminal 200, the heat conducting sheet 400 is arranged on the inner side wall of the accommodating cavity 110 through heat dissipation silicone grease and a snap component, and the heat dissipation component is wrapped around the outer side wall of the connector body 100. The heat dissipation component includes a circular ring-shaped heat dissipation substrate 140 covering the outside of the connector body 100 and a plurality of heat dissipation protrusions 150 annularly arranged on the outside of the circular ring-shaped heat dissipation substrate 140.

[0027] Refer to Figure 4, Preferably, a mesh groove 160 is provided on the side of the annular heat dissipation substrate 140 away from the connector body 100. In this application, the mesh groove 160 is arranged by recessing a plurality of holes on the surface of the annular heat dissipation substrate 140. Through the arrangement of the mesh groove 160, the channels for air flow can be increased, making it easier for the surrounding cold air to enter the surface of the heat dissipation substrate, effectively taking away the heat on the heat dissipation substrate, and thus enhancing the heat dissipation performance of the connector.

[0028] , Preferably, the thermally conductive plastic is ABS thermally conductive plastic or BN / PBT composite engineering thermally conductive plastic. It should be noted that the ABS thermally conductive plastic or BN / PBT composite engineering thermally conductive plastic has excellent thermal conductivity, can effectively conduct the heat inside the connector, disperse the heat to the surface of the connector body 100, and helps to improve the overall heat dissipation effect. At the same time, the ABS thermally conductive plastic and BN / PBT composite engineering thermally conductive plastic have good heat resistance, mechanical strength and corrosion resistance, can meet the requirements of the connector in different working environments, and ensure the stability and reliability of the connector.

[0029] , Preferably, the heat dissipation sheet 400 is a thermally conductive silicone sheet, a graphite heat dissipation sheet 400 or a phase change heat dissipation gasket. The heat dissipation sheet 400 made of the above materials has excellent thermal conductivity, can effectively absorb and conduct the heat inside the connector to the connector body 100, thereby helping to achieve the heat dissipation effect of the connector. Preferably, the heat dissipation assembly can adopt a heat dissipation assembly with good heat dissipation effect such as insulated magnesium alloy, PEEK or PS, and is arranged outside the connector body 100 through an integrated or snap-fastening setting. It should be noted that the heat dissipation protrusion 150 can be set as a heat dissipation fin with a certain arc cross-section, arranged along the axial direction of the connector body 100 and evenly arranged along the circumferential direction of the side surface of the connector body 100 outside the connector body 100. The heat dissipation protrusion 150 can also be set as a convex wavy shape and densely arranged on the outer surface of the connector body 100. Of course, it can also be in the shape of a cylinder, a frustum of a cone or a convex block and densely arranged on the side surface of the housing.

[0030] Refer to Figure 1 , Preferably, a square mounting plate 170 is provided outside the open end of the connector body 100. One end of the mounting plate 170 is hinged with a connector cover 180, and the other end of the mounting plate 170 is detachably connected to the other end of the connector cover 180. It should be noted that mounting holes 190 are provided at the four corners of the mounting plate 170. During installation, the mounting holes 190 are aligned with the mounting holes 190 at the mounting position, and screws are screwed in to achieve installation and use. The setting of the connector cover 180 enables the opening of the accommodating cavity 110 to be shielded when the connector is not in use, playing a role in dust and water prevention.

[0031] Refer toFigure 1 Furthermore, the mounting plate 170 is rotatably connected to the connector cover 180 by a rotating shaft 500. A spring is provided outside the rotating shaft 500. One end of the spring is connected to the mounting plate 170, and the other end of the spring is connected to one end of the spring. When the connector is not in use, the connector cover 180 can automatically cover the opening of the accommodation cavity 110 under the action of the spring. Specifically, the function of the spring is to provide a restoring force, so that the connector cover 180 can automatically close after use and maintain the sealing and dust-proof properties of the connector.

[0032] Refer to Figure 1 Preferably, a hook 510 and a first locking hole 520 are provided at one end of the connector cover 180 away from the rotating shaft 500. A clamping groove 530 and a second locking hole 540 that cooperate with the hook 510 and the first locking hole 520 are provided on the mounting plate 170. The cooperation between the hook 510 and the clamping groove 530 can initially fix the connector cover 180 to the connector body 100, and the settings of the first locking hole 520 and the second locking hole 540 enable a lock to be inserted to further fix the connector cover 180 to the connector body 100.

[0033] Refer to Figure 1 Preferably, an annular accommodation groove is annularly provided on the side of the mounting plate 170 close to the connector cover 180. An annular rubber ring 550 is provided in the annular accommodation groove, and the center of the annular rubber ring 550 coincides with the center of the opening of the accommodation cavity 110. The setting of the annular rubber ring 550 can effectively prevent external impurities such as dust and water vapor from entering the connector, thereby protecting the normal operation of the internal components of the connector.

[0034] Refer to Figures 1 to 3 Preferably, a metal sleeve cap is provided at the bottom of the inner terminal 300, and a return spring is sleeved outside the metal sleeve cap. The bottom of the return spring abuts against the outer terminal 200. When the connector is inserted into the mating male socket plug, first the return spring is compressed, which facilitates the insertion of the male socket plug. Then the male socket plug rotates a certain angle. At this time, the positioning pin on the male socket plug aligns with the positioning hole provided in the outer terminal 200. Then the return spring provides an upward squeezing force, which enables the positioning pin to abut in the positioning hole, thereby making the connection between the male socket plug and the connector firm.

[0035] Refer to Figure 2 Preferably, a through hole 560 is provided through the middle of the side of the connector body 100, and a micro switch is connected to the through hole 560. When the male socket plug is connected to the connector, the micro switch is connected to the male socket plug, thereby sending a signal to the connector to activate the power supply.

[0036] Preferably, a screw rod 570 is provided at one end of the connector body 100 away from the opening of the accommodation cavity 110, and the screw rod 570 is connected to the bottom of the outer terminal 200.

[0037] The utility model provides a connector with high heat dissipation efficiency, which comprises a connector body 100 made of heat-conducting plastic, an outer terminal 200, an inner terminal 300, a heat-conducting sheet 400 and a heat dissipation assembly. The heat-conducting sheet 400 is installed on the inner side wall of the connector body 100 and can effectively absorb and conduct the heat inside the connector to the connector body 100 made of heat-conducting plastic. The connector body 100 made of heat-conducting plastic has good heat-conducting performance and can effectively receive and disperse the heat generated inside the connector. The heat dissipation assembly arranged outside the connector body 100 adopts a circular heat dissipation substrate 140 and a structure of annularly arranged heat dissipation protrusions 150, which effectively increases the heat dissipation surface area, improves the heat dissipation efficiency, helps to quickly dissipate the heat generated inside the connector, thereby effectively reducing the working temperature of the connector. At the same time, the arrangement of the heat dissipation protrusions 150 also plays a role in anti-slip when the connector is installed. Therefore, the connector with high heat dissipation efficiency can effectively disperse the heat generated inside the connector, extend the service life of the connector, and improve the reliability and stability of the product.

[0038] The above-disclosed are only several preferred embodiments of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby.
