Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a water-electricity combined connector. Background Art

[0002] Traction converter systems and auxiliary converter systems with high-power heating units need to use water cooling to assist in heat dissipation when the original air cooling and auxiliary heat sinks cannot meet the heat dissipation requirements. Existing water cooling generally uses a solution that combines terminal blocks with fluid connectors. On this basis, in order to facilitate installation, use, maintenance and modular expansion, water-electric combined connectors are now often used to dissipate heat for traction converter systems and auxiliary converter systems.

[0003] The hydroelectric combined connector integrates the fluid connector and the electrical connector into one. By controlling the plugging and separation of the fluid connector and the electrical connector, the cooling liquid and electrical signals inside the locomotive inverter module system can be connected and disconnected. The hydroelectric combined connector has various forms, is easy to operate, has reliable connection, and is easy to maintain. It is currently the most widely used solution for traction inverter systems and auxiliary inverter systems in the rail transit field.

[0004] However, with the development of intelligent and high-speed electrified railways, traditional converters can no longer meet the requirements of lightweight and miniaturization in some special applications, so reducing volume and weight has become a new development trend. High frequency is the most commonly used method at this stage, but it is accompanied by an increase in AC loss of electrical connectors due to high frequency and a decrease in effective heat dissipation area due to miniaturization, which ultimately leads to serious heating or even burning of the system.

[0005] The existing water-electric combined connector only sets a fluid connector at a certain distance around the electrical connector for cooling, but cannot directly cool the heat-generating core part of the electrical connector. Due to the distance between the fluid connector and the electrical connector and the isolation of the connector housing, the cooling efficiency is low and the cooling effect is poor, which seriously limits the development of high power, miniaturization and lightweight of the system.

[0034] The present invention provides a water-electricity combined connector, such as Figures 1 to 4 As shown, the water-electricity combined connector includes a fixed side module 100 and a movable side module 200 .

[0035] In the following description, reference will be made to Figures 1 to 4 The specific structure of the above components of the water-electricity combined connector and the connection relationship of the above components are specifically described.

[0036] like Figures 1 to 4 As shown, in the embodiment, a plurality of plugs 2 may be provided on the fixed side module 100. A second cavity 20 may be formed inside the plug 2. The first end of the plug 2 (which may be Figure 3 The right end shown in FIG. 1 ) and the second end of the plug 2 (which may be Figure 3The left end as shown) can be connected through the second cavity 20, so that the coolant can flow from the first end of the plug 2 to the second end of the plug 2 through the second cavity 20. Preferably, the coolant is an insulating coolant. The first end of the plug 2 can be connected to a pipeline for the coolant to flow in. And the first end of the plug 2 can be conductively connected to the cable. The active side module 200 can be installed on the converter power module, and the converter power module can be a power module of the traction converter system or the auxiliary converter system of the vehicle. A plurality of sockets 1 can be provided on the active side module 200. A first cavity 10 is formed inside the socket 1. The first end of the socket 1 (which can be as shown Figure 2 The right end shown in FIG. 1 is connected to the second end of the socket 1 (which can be Figure 2 The left end shown in the figure) can be connected through the first cavity 10, so that the coolant can flow from the second end of the socket 1 to the first end of the socket 1 through the first cavity 10. The first end of the socket 1 can be connected to the pipeline for flowing out the coolant. And the first end of the socket 1 can be conductively connected to the copper busbar of the converter power module. In addition, the second end of the plug 2 can be plugged and matched with the second end of the socket 1, so that the second cavity 20 of the plug 2 is connected to the first cavity 10 of the socket 1, so that the coolant can flow inside the plug 2 and the socket 1 to dissipate heat. And the plug 2 can be conductively connected to the socket 1, so that the cable is conductively connected to the copper busbar of the converter power module. In this way, while the plug 2 and the socket 1 are conducting, the coolant can directly dissipate heat from the inside of the plug 2 and the socket 1, greatly enhancing the heat dissipation capacity.

[0037] like Figure 1 As shown, in an embodiment, the fixed side module 100 may include a fixed side mounting plate 3. A plurality of plugs 2 may be provided on the fixed side mounting plate 3. The movable side module 200 may include a movable side mounting plate 4. A plurality of sockets 1 may be provided on the movable side mounting plate 4. Specifically, the shape and size of the fixed side mounting plate 3 and the movable side mounting plate 4 may be the same. Among them, the fixed side mounting plate 3 may be installed on a coolant pipeline, and the coolant pipeline may be connected to the plug 2 on the fixed side mounting plate 3. The movable side mounting plate 4 may be installed on a converter power module, and the socket 1 on the movable side mounting plate 4 may be connected to a copper busbar of the converter power module. Further preferably, as Figure 1 In the embodiment shown, four plugs 2 may be provided on the fixed side mounting plate 3, and four sockets 1 may be provided on the movable side mounting plate 4. The plugs 2 and the sockets 1 may be provided in a one-to-one correspondence, so that four plugs 2 and four sockets 1 can be plugged and matched simultaneously. Providing multiple plugs 2 to match multiple sockets 1 can further improve the heat dissipation capacity of the water-electricity combined connector.

[0038] More preferably, Figure 1As shown, in an embodiment, the active side module 200 can be installed on the liquid cooling plate of the converter power module. Specifically, a guide pin 5 (which can be threaded) can be installed on the liquid cooling plate of the converter power module, and the axial direction of the guide pin 5 can be perpendicular to the plate surface of the active side mounting plate 4. A through hole can be opened on the active side mounting plate 4, and the guide pin 5 can be inserted into the through hole to position the active side mounting plate 4. A guide sleeve 30 can be installed on the fixed side mounting plate 3, and the guide sleeve 30 can be threadedly connected to the fixed side mounting plate 3. The position of the guide sleeve 30 corresponds to the position of the guide pin 5, so that when the plug 2 is plugged in with the socket 1, the guide pin 5 can be inserted into the guide sleeve 30 to play a guiding role. Preferably, the number of the guide pin 5 and the guide sleeve 30 can be two, and the two guide sleeves 30 can be respectively arranged at the upper and lower parts of the fixed side mounting plate 3.

[0039] In addition, preferably, Figure 1 As shown, in the embodiment, an error-proofing component 6 may also be provided on the fixed side mounting plate 3 and the movable side mounting plate 4. Specifically, a plurality of first threaded holes may be provided on the side of the fixed side mounting plate 3 facing the movable side mounting plate 4, and a plurality of second threaded holes may be provided on the side of the movable side mounting plate 4 facing the fixed side mounting plate 3, wherein the first threaded holes are equal in number to the second threaded holes and are arranged in alignment. The error-proofing component 6 may be a rod with an external thread provided at the end, and the error-proofing component 6 may be installed in the first threaded hole or the second threaded hole. When in use, the operator may install the error-proofing component 6 in part of the first threaded hole on the fixed side mounting plate 3, and install the error-proofing component 6 in part of the second threaded hole on the movable side mounting plate 4, and make the setting positions of the error-proofing components 6 on the fixed side mounting plate 3 and the movable side mounting plate 4 arranged in groups not overlap. With such an arrangement, in the case of having multiple groups of fixed side modules 100 and movable side modules 200, incorrect docking of fixed side modules 100 and movable side modules 200 of different groups may be avoided. For example, in the case of Figure 1 In the illustrated embodiment, the threaded holes on the fixed side mounting plate 3 and the movable side mounting plate 4 are arranged in two vertical rows. The movable side mounting plate 4 is installed with the error-proofing component 6 in the second threaded hole in one row, while the fixed side mounting plate 3 is installed with the error-proofing component 6 in the first threaded hole in the other row, so that when the fixed side mounting plate 3 is docked with the movable side mounting plate 4, the error-proofing component 6 in the first threaded hole will not abut against the error-proofing component 6 in the second threaded hole, so as to confirm that the two are the fixed side mounting plate 3 and the movable side mounting plate 4 set in the same group. On the contrary, if the error-proofing component 6 abuts against each other during the docking process, it means that the fixed side module 100 and the movable side module 200 are not set in the same group. In this way, the operator can avoid docking errors.

[0040] Preferably, Figure 1 , Figure 2 and Figure 4 As shown, in an embodiment, the socket 1 may include a socket back sleeve 11, a socket insulator 12, a socket spring 13, a first adapter sleeve 14 and a first sealing assembly 15.

The socket insulator 12 may be a jacket made of PPT (plastic). The socket insulator 12 may be sleeved on the outside of the socket back sleeve 11. The socket back sleeve 11 may be clamped inside the socket insulator 12 by a retaining ring, and the first end of the socket back sleeve 11 (which may be as shown in FIG. Figure 2 The right end shown in FIG. 1 ) may extend from the first end of the socket insulator 12 (which may be as shown in FIG. Figure 2 The socket insulator 12 can be mounted on the movable side mounting plate 4 by means of a retaining ring. The socket spring 13 can be formed in a ring shape. The socket spring 13 can be arranged inside the socket back cover 11. The socket spring 13 can be located at the second end of the socket 1 (i.e., as shown in FIG. 1 ). Figure 2 As shown, the jack spring 13 is arranged at the left end of the jack rear sleeve 11). The jack rear sleeve 11 may have an installation groove formed inside, and the jack spring 13 may be clamped in the installation groove. The first adapter sleeve 14 may be installed at the end of the jack rear sleeve 11. The first adapter sleeve 14 is located at the first end of the socket 1 (i.e., Figure 2 As shown in the figure, the first adapter sleeve 14 is installed at the right end of the socket rear sleeve 11). The first sealing component 15 can be arranged inside the socket rear sleeve 11. Preferably, the first sealing component 15 is arranged between the socket spring 13 and the first adapter sleeve 14. The first sealing component 15 can block the first cavity 10, so that the coolant cannot flow from the first end of the socket 1 to the second end. When the plug 2 is plugged into the socket 1, the first sealing component 15 no longer blocks the first cavity 10, so that the two ends of the socket 1 can be connected.

The end of the sealing rod 16 close to the second end of the socket 1 (i.e., Figure 2 The left end of the sealing rod 16 shown in FIG. 1 may be formed as a stop end 161. The end of the sealing rod 16 away from the second end of the socket 1 (i.e., as shown in FIG. 1 ) may be formed as a stop end 161. Figure 2 The right end of the sealing rod 16 shown in FIG. 1 may be formed as a fixed end 162. Preferably, the stop end 161 may be formed as a columnar structure with a gradually decreasing diameter. Specifically, the diameter of the stop end 161 may be as follows: Figure 2As shown, it gradually decreases from left to right. The diameter of the stop end 161 is smaller than the aperture of the jack rear sleeve 11, so that the coolant can flow between the stop end 161 and the inner wall of the jack rear sleeve 11. The fixed end 162 can be formed into a circular plate-shaped structure. The fixed end 162 can be fixed in the jack rear sleeve 11 by a retaining ring. In addition, a through hole 163 can be provided on the fixed end 162 for the circulation of coolant. The sealing ring 17 can be sleeved on the stop end 161 of the sealing rod 16, that is, the sealing ring 17 can be arranged between the inner wall of the jack rear sleeve 11 and the sealing rod 16. Preferably, an O-ring is arranged between the sealing ring 17 and the inner wall of the jack rear sleeve 11, and an O-ring is arranged between the sealing ring 17 and the stop end 161 to play a sealing role. In addition, the sealing ring 17 can move along the axial direction of the sealing rod 16. When the sealing ring 17 is sleeved at the largest diameter of the stop end 161, the first sealing assembly 15 can block the first cavity 10. When the sealing ring 17 moves to the smaller diameter of the stop end 161, the coolant can flow between the stop end 161 and the inner wall of the rear sleeve 11 of the jack. The first spring 18 can be arranged between the sealing ring 17 and the fixed end 162 of the sealing rod 16. The two ends of the first spring 18 can respectively abut against the sealing ring 17 and the fixed end 162, and are used to drive the sealing ring 17 to reset, so as to ensure that the first sealing assembly 15 can block the first cavity 10 under normal conditions.

An O-ring for sealing may be disposed between the front housing 23 and the inner wall of the plug pin 21. The second adapter sleeve 24 may be installed at the end of the plug pin 21. The second adapter sleeve 24 is located at the first end of the plug 2 (i.e., Figure 3 As shown, the second adapter sleeve 24 is installed at the right end of the pin 21). The second sealing component 25 can be partially arranged inside the front housing 23. The second sealing component 25 can block the second cavity 20, so that the coolant cannot flow from the first end of the plug 2 to the second end. When the plug 2 is plugged into the socket 1, the second sealing component 25 no longer blocks the second cavity 20, so that the two ends of the plug 2 can be connected.

Preferably, a first inclined surface 231 may be formed inside the front housing 23, that is, Figure 3 As shown, the inner diameter of the left end of the front shell 23 gradually increases from left to right to form a first inclined surface 231. The side of the sealing block 26 facing the first inclined surface 231 may be formed with a second inclined surface 261. The second inclined surface 261 is arranged parallel to the first inclined surface 231. When the first inclined surface 231 abuts against the second inclined surface 261, the second sealing assembly 25 can block the second cavity 20. Preferably, an O-ring for sealing may be arranged between the sealing block 26 and the inner wall of the front shell 23.

The second end of the first adapter sleeve 14 can be formed with an external thread for connection with a coolant pipeline. The first adapter sleeve 14 can be connected to the liquid cooling plate of the converter power module through the coolant pipeline, so that the coolant flowing into the socket 1 can flow into the liquid cooling plate. Preferably, the outer wall of the first adapter sleeve 14 can be formed with a first boss portion 140 protruding in the radial direction, and the first boss portion 140 can be an annular boss. When the first end of the first adapter sleeve 14 is screwed into the first end of the socket rear sleeve 11, the first boss portion 140 is close to the end of the socket rear sleeve 11, and the copper busbar of the converter power module can be clamped and fixed between the first boss portion 140 and the end of the socket rear sleeve 11 to achieve conductive connection between the socket 1 and the converter power module.

[0047] More preferably, Figure 1 , Figure 3 and Figure 4 As shown, in the embodiment, the first end of the second adapter sleeve 24 (which can be Figure 3 The left end shown in FIG. 1 may be connected to the first end of the pin 21 (which may be Figure 3 The right end as shown) is threadedly connected, and the second end of the first adapter sleeve 14 (which can be Figure 3 The left end shown in the figure) can be connected with the pipeline thread. Specifically, the first end of the second adapter sleeve 24 can be formed with an external thread, and the first end of the pin 21 can be formed with an internal thread, and the first end of the second adapter sleeve 24 can be screwed into the first end of the pin 21. Preferably, an O-ring for sealing can be provided between the outer wall of the second adapter sleeve 24 and the inner wall of the pin 21. The second end of the second adapter sleeve 24 can be formed with an external thread for connection with a coolant pipeline. The coolant can flow into the plug 2 through the coolant pipeline, and then flow from the plug 2 to the socket 1, so as to cool the plug 2 and the socket 1. Preferably, the outer wall of the second adapter sleeve 24 can be formed with a second boss portion 240 protruding in the radial direction, and the second boss portion 240 can be an annular boss. When the first end of the second adapter sleeve 24 is screwed into the first end of the pin 21, the second boss portion 240 is close to the end of the pin 21, and the cable terminal can be clamped and fixed between the second boss portion 240 and the end of the pin 21 to achieve a conductive connection between the plug 2 and the external cable, and then the converter power module is conductively connected to the external cable through the plug 2 and the socket 1.

[0048] During use, the water-electricity combined connector connects the converter power module to the external cable through the plug 2 and the socket 1, and a passage is provided in the plug 2 and the socket 1 to circulate the coolant, so as to dissipate heat from the inside of the plug 2 and the socket 1, thereby greatly enhancing the heat dissipation capacity of the water-electricity combined connector. Compared with the traditional water-electricity combined connector, which sets a fluid connector at a certain distance around the electrical connector for cooling, the water-electricity combined connector has a better cooling effect, thereby reducing the volume of components such as the cooling pump, so as to achieve the purpose of miniaturization and lightness of the overall system.
