[0007] Preferably, the heat dissipation base plate is stepped, and the middle connecting portion between the left and right table surfaces of the heat dissipation base plate is inclined.

[0008] Preferably, the elastic holding plate is connected and arranged on the right side table of the heat dissipation base plate.

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are the same as Figure 1 The view direction is consistent in front, back, left, right, up and down. Figure 1The direction shown is consistent with the front, back, left, right, up and down directions of the device of the utility model when viewed from the front.

[0024] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of at least two elements or the interaction relationship between at least two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] See also Figure 1-6 The utility model provides an embodiment: a charging connector auxiliary device, comprising a charging connector 10, a heat dissipation base plate 33 and an elastic holding plate 31, wherein the heat dissipation base plate 33 is made of high-strength metal material and has good heat dissipation, durability and safety, and is fixed to the bottom of the connector 11 in the charging connector 10,

[0027] It should be noted that the heat dissipation bottom plate 33 is stepped, and the middle connecting part of the left and right tables of the heat dissipation bottom plate 33 is inclined. The upper end surface of the connector 11 is connected to a curved handle 20, and bolts 21 are respectively fixedly inserted on both sides of the curved handle 20. Each of the bolts 21 passes through the fixing holes on both sides of the connector 11 and is fixedly connected to the left table of the heat dissipation bottom plate 33.

[0028] The elastic clamping plate 31 is then fixedly mounted on the right side surface of the heat dissipation base plate 33 by passing through the through holes in the straight plate portions at both ends of the elastic clamping plate 31 with screws 32. Since the middle portion of the elastic clamping plate 31 is arched, the cable 12 connected to the tail end of the charging connector 10 passes through the arched portion in the middle, so that the cable 12 is compressed by the elastic clamping plate 31 to achieve stable fixation of the cable. In addition, the overall structural design is compact and easy to operate.

[0029] In specific implementation, it is only necessary to fix the heat dissipation base plate 33 and the connector 11, place the cable 12 on the heat dissipation base plate 33, and then tightly fix it with the elastic clamping plate 31 through the screws 32. The stable fixation of the cable is achieved through the synergistic effect of the heat dissipation base plate 33 and the elastic clamping plate 31. When the base plate and the charging connector are locked and fixed by screws, it is effectively prevented that the cable is loosened or falls off in the charging connector during the plugging and unplugging process of the charging connector due to improper human operation, thereby ensuring the stability and reliability of charging. At the same time, the auxiliary device of the charging connector also has the function of effectively reducing the temperature of the charging connector, which can effectively dissipate the heat generated by the cable during charging work, thereby reducing the temperature of the charging connector. This innovative design not only protects the life of the charging connector, but also avoids safety hazards caused by high temperature.

[0030] In summary, the auxiliary device of the utility model has the following advantages:

[0031] (1) Good stability, which can effectively prevent the cable and charging connector from separating and falling off;

[0032] (2) Easy to operate, no special skills or tools required;

[0033] (3) The material is durable and can withstand use in harsh environmental conditions;

[0034] (4) Can significantly reduce overheating of the charging connector.

[0035] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
