In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0041] The following will describe the air-cooled connector of the present invention in conjunction with Figure 1-Figure 6 Describe the air-cooled connector of the present invention.

[0042] As Figure 4 shown, the air-cooled connector in the embodiment of the present invention mainly includes a contact body 1 and a sleeve 2. The contact body 1 is used to connect the end of a cable, and the sleeve 2 is sleeved outside the contact body 1. An air-cooling cavity 3 is formed between the inner side wall of the sleeve 2 and the outer side wall of the contact body 1. An air inlet 4 and an air outlet 5 communicating with the air-cooling cavity 3 are provided on the surface of the sleeve 2. Among them, the air inlet 4 is connected to an air inlet pipe 21, and the air inlet pipe 21 is adapted to be connected to an air-cooling unit.

[0043] In this embodiment, the circuit is conducted by connecting the end of the cable with the contact body 1. The sleeve 2 is sleeved outside the contact body 1, and an air-cooling cavity 3 is formed between the sleeve 2 and the contact body 1. The air-cooling unit and the air inlet pipe 21 are used to provide a cooling air flow for the air-cooling cavity 3. When the cooling air flow passes through the contact body 1 in the air-cooling cavity 3, the Joule heat generated by the contact body 1 can be taken away, thereby cooling the contact body 1 to avoid hazards such as thermal failure, electric leakage, and fire caused by the inability of the contact body 1 to dissipate heat, and ensuring the safe use of the connector.

[0044] For the air-cooled connector adopting the above method, compared with the traditional high-current connector, the operating temperature is significantly reduced, and the service life of its components is longer. Moreover, the structure of this liquid-cooled connector is simple, and almost no additional volume is increased, and the impact on the occupied space is small.

[0045] It can be understood that the air-cooling unit provides a cooling air flow. The cooling air flow enters the air-cooling cavity 3 through the air inlet pipe 21. After the cooling air flow blows over the surface of the contact body 1, the heat of the contact body 1 can be taken away, reducing the working temperature of the contact body 1, and then the heat is discharged with the air flow from the air outlet 5 to achieve the heat dissipation of the contact body 1.

[0046] To ensure the air-cooling effect, the air inlet 4 and the air outlet 5 are located on opposite sides of the sleeve 2, so that after the cooling air flow enters the air-cooling cavity 3 from the air inlet 4, the cooling air flow can at least cover half of the outer surface of the contact body 1. Among them, the air inlet 4 can be located on the upper surface of the sleeve 2, and at this time the air outlet 5 can be located on the lower surface of the sleeve 2. The air inlet 4 can also be located on the lower surface of the sleeve 2, and at this time the air outlet 5 can be located on the upper surface of the sleeve 2. That is, the cooling air flow can enter from the top and exit from the bottom or enter from the bottom and exit from the top. Of course, the cooling air flow can also adopt other inlet and outlet methods, which will not be elaborated here.

[0047] The sleeve 2 is an insulating sleeve. For example, the sleeve 2 can be made of rubber.

[0048] The air outlet 5 may also be connected to an air outlet pipe 22, so as to guide the airflow to a specific area for discharge, thereby avoiding airflow disturbance. It should be noted that a valve is provided on the air outlet pipe 22 or the air outlet 5 to control the conduction of the air outlet pipe 22 or the air outlet 5. When the air cooling unit is not started, the valve controls the air outlet pipe 22 or the air outlet 5 to be closed, so as to prevent dust from entering the air cooling chamber 3.

[0049] like Figure 4 and Figure 5 As shown, the inner wall of the sleeve 2 is configured with a first annular groove 6, and the outer wall of the contact body 1 is configured with a second annular groove 7. The positions of the first annular groove 6 and the second annular groove 7 correspond to each other, and the area between the first annular groove 6 and the second annular groove 7 forms an air-cooling chamber 3.

[0050] The first annular groove 6 is recessed in the inner wall of the sleeve 2, and the second annular groove 7 is recessed in the outer wall of the contact body 1. The first annular groove 6 and the second annular groove 7 are arranged opposite to each other so that the notches of the first annular groove 6 and the second annular groove 7 are connected to form an air-cooling chamber 3.

[0051] Correspondingly, both the air inlet 4 and the air outlet 5 are provided with areas on the sleeve 2 corresponding to the first annular groove 6 .

[0052] like Figure 5 As shown, an annular heat sink 8 is provided in the second annular groove 7, and the annular heat sink 8 can increase the heat exchange area between the cooling airflow and the contact body 1, thereby accelerating the heat dissipation and ensuring the heat exchange efficiency. Among them, at least two annular heat sinks 8 are provided, one of which abuts against the inner side wall of the first annular groove 6, or two of which abut against the inner side walls of the first annular groove 6 on opposite sides. The annular heat sink 8 increases the heat dissipation area on the one hand, and can fix the contact body 1 in the sleeve 2 on the other hand.

[0053] In order to further increase the heat dissipation area, heat dissipation fins may be connected to the outer surface of the contact body 1 , and the heat dissipation fins are located in the air cooling cavity 3 , thereby accelerating the heat dissipation.

[0054] like Figure 4 As shown, the left side of the contact body 1 is engaged with the stepped groove on the inner wall of the sleeve 2, and the right side of the contact body 1 forms a second annular groove 7. The right side of the second annular groove 7 is provided with an annular heat sink 8 and then abuts against the right side of the first annular groove 6. Thus, both the left and right sides of the contact body 1 can be fixed.

[0055] According to the air-cooled connector provided by the present invention, the air-cooled unit includes a fan, the air outlet of the fan is connected to the air inlet pipe 21, and the air inlet pipe 21 or the air inlet end of the fan is provided with an air filter. It can be understood that the air filter can filter dust, sand and the like in the cooling air flow, so as to prevent dust and sand from entering the air-cooling chamber 3 and affecting the heat dissipation of the contact body 1, and also to prevent dust and sand from entering the air-cooling chamber 3 and wearing the contact body 1.

[0056] The filtration efficiency of the air filter is not less than 99%. The air filter can be a straight-through cyclone tube air filter or other types of air filters, which are not limited in this embodiment. The model of the fan can be selected according to the air volume of the cooling air flow. The fan can be equipped with a power control system, which can adjust the appropriate air volume according to the working temperature of the connector, thereby ensuring the cooling performance and achieving energy saving effect.

[0057] like Figure 1 and Figure 2 As shown, the air-cooled connector in the embodiment of the present invention also includes a shell 9, the sleeve 2 is suitable for being fixed in the shell 9 through a connecting mechanism, the shell 9 is provided with a clearance hole, the air inlet pipe 21 is suitable for being inserted into the clearance hole, and is fixed to the shell 9 through a locking mechanism.

[0058] The position of the sleeve 2 and the connector can be fixed and protected by the housing 9, and the interior of the housing 9 is hollow to facilitate the placement of the sleeve 2. Figure 1 As shown, the left and right sides of the housing 9 are respectively formed with openings, so that the ends of the cables can be inserted into the housing 9 from both ends, thereby connecting with both ends of the contact body 1. The upper and lower sides of the housing 9 are respectively formed with clearance holes, so as to respectively penetrate the air inlet pipe 21 and the air outlet pipe 22.

[0059] like Figure 1 As shown, both upper and lower sides of the housing 9 are provided with inclined surfaces, the inclined surfaces on the upper and lower sides are inclined close to each other, and the relinquishing holes are respectively arranged on the two inclined surfaces. This shape design facilitates the housing 9 to avoid other parts during installation, and facilitates the installation and fixing of the housing 9.

[0060] In this embodiment, the locking mechanism includes an annular connecting portion 10 and a locking portion 12. The annular connecting portion 10 is fixed to the outer side of the housing 9. A connector 11 is extended from a part of the annular connecting portion 10 away from the housing 9 in a direction away from the annular connecting portion 10. The locking portion 12 is suitable for being connected to the connector 11 through a locking member. The air inlet pipe 21 is suitable for being inserted into the annular connecting portion 10. The locking portion 12 and the connector 11 form an annular structure to lock the air inlet pipe 21.

[0061] like Figure 1As shown, one end of the air inlet pipe 21 is connected to the air inlet 4, and the other end passes through the clearance hole. The air inlet pipe 21 is locked at the position of the clearance hole by a locking mechanism to fix the position of the air inlet pipe 21.

[0062] It is understandable that the central part of the annular connecting portion 10 forms an opening, and the shape and size of the opening are the same as the shape and size of the air inlet pipe 21. When the air inlet pipe 21 is a round pipe, the opening is a round hole, and when the air inlet pipe 21 is a square pipe, the opening is a square hole. Ensure that the air inlet pipe 21 can pass through the annular connecting portion 10.

[0063] The annular connecting portion 10 extends out of a connecting head 11 from a partial area on one side of the outer shell 9 and is used to connect to the locking portion 12. After the locking portion 12 is closed and connected to the connecting head 11, it can form the same shape as the annular connecting portion 10, thereby embracing the air inlet pipe 21, and cooperates with the fasteners to form a tight connection between the locking piece and the connecting head 11, so as to firmly clamp the air inlet pipe 21.

[0064] like Figure 6 As shown, the connector 11 is integrally formed on the side of the annular connecting portion 10 away from the outer shell 9. The connector 11 is configured as a semicircular ring structure, and correspondingly, the locking member is also configured as a semicircular ring structure. At this time, the connector 11 and the locking member are connected to form an annular structure, thereby clamping and fixing the air inlet pipe 21.

[0065] The connector 11 is provided with a first locking hole 13, and the locking portion 12 is provided with a second locking hole 14. The first locking hole 13 and the second locking hole 14 are adapted to each other, and the first locking hole 13 and the second locking hole 14 are suitable for being fixed by a fastener. For example, the fastener is a bolt.

[0066] It is understandable that the first locking hole 13 on the connector 11 and the second locking hole 14 on the locking portion 12 are located at corresponding positions and have the same size. When the locking portion 12 is connected to the connector 11, the first locking hole 13 and the second locking hole 14 are aligned, and the connector 11 and the locking portion 12 are securely fixed by inserting a fastener through the first locking hole 13 and the second locking hole 14.

[0067] To ensure the penetration of the fastener, the first locking hole 13 and the second locking hole 14 are both through-holes.

[0068] like Figure 6 As shown, the outer circumference of the annular connecting portion 10 is provided with a connecting ear 15, the connecting ear 15 is provided with a connecting hole 16, the surface of the housing 9 is configured with a mounting hole, and the connecting hole 16 and the mounting hole are suitable for being connected by a fastener. Exemplarily, the fastener is a screw.

[0069] The annular connecting part 10 is fixed in position by providing a connecting ear 15 on the outer circumferential surface of the annular connecting part 10 and using a fastener to penetrate the connecting hole 16 and the mounting hole. In this way, the annular connecting part 10 can be detachably connected to the housing 9, so as to facilitate the maintenance and replacement of the annular connecting part 10.

[0070] A plurality of connecting ears 15 are arranged at intervals on the outer peripheral surface of the annular connecting part 10. Correspondingly, a plurality of mounting holes are arranged in an annular shape on the surface of the outer shell 9. The plurality of connecting ears 15 are connected to the plurality of mounting holes to achieve reliable connection of the annular connecting part 10.

[0071] According to the air-cooled connector provided by the present invention, the connection mechanism includes a connection column 17, an adapter 18, a connection member 19 and a fixing plate 20. The connection column 17 is arranged on the inner side wall of the housing 9. The adapter 18 is connected to the connection column 17 through a fastener. The connection member 19 is connected to the adapter 18. The fixing plate 20 is provided with a sleeve hole. The fixing plate 20 is suitable for being sleeved on the outside of the sleeve 2 through the sleeve hole. The fixing plate 20 and the connection member 19 are suitable for being connected by fasteners. Exemplarily, the fastener is a screw.

[0072] like Figure 2 As shown, the connecting column 17 can be arranged along the length direction of the housing 9, and a threaded hole is provided on the side of the connecting column 17 facing the adapter 18. The adapter 18 is set to be L-shaped, and a through hole is provided on the side of the adapter 18 connected to the connecting column 17, so that the through hole and the threaded hole are connected by fasteners to achieve a reliable connection between the adapter 18 and the connecting column 17. The other end of the adapter 18 is bent downward and connected to the connecting plate, and the connecting plate is connected to the fixing plate 20 through the fasteners, and then the fixing plate 20 is sleeved on the outside of the sleeve 2 through the sleeve hole to achieve the connection between the two, so as to fix the sleeve 2 to the inside of the housing 9.

[0073] The L-shaped adapter 18 is suitable for being integrally formed with the connecting member 19 .

[0074] The connecting piece 19 can be set to be long and strip-shaped, and installed vertically in the housing 9, and the adapter 18 is integrally formed on both the upper and lower sides of the connecting piece 19. At the same time, two connecting pieces 19 can be set, and the two connecting pieces 19 are respectively located on both sides of the sleeve 2. In this case, the inner wall of the housing 9 is respectively provided with two connecting columns 17 on both sides of the sleeve 2, so as to connect the adapters 18. In this way, multi-point connection and fixation can be formed, so that the position fixation of the sleeve 2 is more secure.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
