Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a hybrid high-voltage connector. Background Technology

[0002] Traditional connectors typically consist of male and female terminals that can be separably plugged in to transmit current or signals. Currently, hybrid connectors used in high-voltage industries further secure the male and female terminals with locking mechanisms after plugging in, ensuring a good connection. However, the current locking mechanisms for electrical connectors are cumbersome to assemble, and secondary disassembly and reassembly affect the locking effect, resulting in relatively low production efficiency and significantly impacting the connector's lifespan. Utility Model Content

[0003] The main purpose of this utility model is to provide a hybrid high-voltage connector, which aims to solve the technical problems of the current electrical connector locking structure being difficult to assemble and affecting the service life of the connector.

[0004] To achieve the above objectives, the present invention proposes a hybrid high-voltage connector, comprising:

[0005] A first connector is used to connect a first wire group, and the first connector is provided with a slot.

[0006] A second connector is used to connect a second wire group. The first connector and the second connector are in a plug-in connection state, in which the first wire group and the second wire group are connected. The second connector has a groove and a notch. The groove extends circumferentially along the second connector. A blocking block is provided in the groove. The blocking block has a first clearance surface, which is inclined. The notch is disposed opposite to the first clearance surface.

[0007] The locking sleeve has a cavity adapted to the second connector. The inner wall of the cavity is provided with a limiting block and a locking block. The locking sleeve moves along the axial direction of the second connector, so that the limiting block passes through the notch and slides along the first clearance surface into the slide groove. In the connected state, the locking block engages with the slot. The blocking block is also used to prevent the limiting block from leaving the slide groove on its own.

[0008] In one embodiment, the second connector is further connected to an elastic element. A fixing block is provided at one end of the slide groove away from the blocking block. One end of the elastic element is connected to the fixing block, and the other end is used to press against the limiting block. The locking sleeve rotates circumferentially along the second connector to drive the limiting block to slide along the slide groove and squeeze the elastic element. The locking sleeve has a locked state and an unlocked state. In the locked state, the elastic element drives the locking sleeve to rotate in the opposite direction so that the locking block is engaged in the slot. In the unlocked state, the locking block leaves the slot.

[0009] In one embodiment, the limiting block is further connected to a positioning block, and the second connector is provided with a positioning groove. The positioning groove is provided with a first positioning surface and a second positioning surface that are opposite to each other and cooperate with the positioning block. The extending directions of the first positioning surface and the second positioning surface are consistent with the extending direction of the slide groove. The positioning groove communicates with the slide groove. The locking sleeve moves along the axial direction of the second connector, so that the positioning block slides into the positioning groove and slides along the positioning groove.

[0010] In one embodiment, the locking block is provided with a first guide wall, the slot includes a guide groove and a limiting groove that are interconnected, the guide groove is provided with a second guide wall, when switching from the unlocked state to the locked state, the first guide wall slides along the second guide wall, and the elastic element also drives the locking sleeve to rotate so that the locking block is engaged in the limiting groove.

[0011] In one embodiment, the outer wall of the locking sleeve is further provided with two symmetrically arranged drive ears.

[0012] In one embodiment, the first connector is connected to a plurality of first signal pins and two first power pins, and the second connector is connected to a plurality of second signal pins and two second power pins. The second connector has a second connecting portion, in which the second signal pins and the second power pins are disposed. The locking sleeve is at least partially movably fitted onto the second connecting portion. The first connector has a first connecting portion with a slot. The slot is located on the side wall of the first connecting portion. In the connected state, the first signal pins are inserted into the second signal pins, the first power pins are inserted into the second power pins, the second connecting portion is inserted into the slot, and the locking sleeve is fitted onto the first connecting portion, with the first connecting portion located between the locking sleeve and the second connecting portion.

[0013] In one embodiment, there are eight first signal pins and eight second signal pins, and two first power pins and two second power pins.

[0014] In one embodiment, the second connection portion includes a first region, a second region, and a third region, with a space between each pair of the three regions. A partition is provided in the slot and is inserted into the space. One second power pin is located in the first region, another power pin is located in the second region, and eight second signal pins are located in the third region.

[0015] In one embodiment, the second power pin is provided with a crown spring, the thickness of which is 0.25mm-0.3mm.

[0016] In one embodiment, the second connecting portion is provided with a sealing ring; and / or,

[0017] The first connector has a receiving groove at one end away from the first connecting part. The first wire group is electrically connected to the first signal pin and the first power pin respectively. The first wire group is also at least partially located in the receiving groove. A sealing block is formed in the receiving groove by potting sealant.

[0018] This utility model's technical solution connects the first and second wire groups by interlocking a first connector and a second connector. The second connector has a groove and a notch. A locking sleeve is used to movably fit over the second connector. Specifically, when installing the locking sleeve, the locking sleeve moves along the axial direction of the second connector, causing the limiting block to pass through the notch and slide along the first clearance surface into the groove, thus facilitating the installation of the locking sleeve. When disassembling the locking sleeve, rotating the sleeve causes the limiting block to slide towards the blocking block and disengage from the groove, then leave through the notch. This makes disassembly and assembly convenient, and does not affect the subsequent locking effect, ensuring the service life of the connector. It also improves production and assembly efficiency.

[0035] In current technology, the male and female terminals of hybrid connectors used in the high-voltage industry are secured by a locking structure after insertion to ensure a good connection. However, the current locking structure of electrical connectors is cumbersome to assemble, and secondary disassembly and reassembly affect the locking effect, resulting in relatively low production efficiency and severely impacting the lifespan of the connector.

[0036] This utility model proposes a hybrid high-voltage connector.

[0037] Please see Figures 1 to 5 In one embodiment of this utility model, the hybrid high-voltage connector includes: a first connector 100, a second connector 200, and a locking sleeve 300. The first connector 100 is used to connect a first wire group and has a slot 110. The second connector 200 is used to connect a second wire group. The first connector 100 and the second connector 200 are in a mutually plugged connection state, where the first wire group and the second wire group are connected. The second connector 200 has a groove 210 and a notch 220. The groove 210 extends circumferentially along the second connector 200, and a blocking block is provided within the groove 210. 230, the blocking block 230 is provided with a first clearance surface 231, the first clearance surface 231 is inclined, and the notch 220 is provided opposite to the first clearance surface 231; the locking sleeve 300 is provided with a cavity adapted to the second connector 200, the inner wall of the cavity is provided with a limiting block 310 and a locking block 320, the locking sleeve 300 moves along the axial direction of the second connector 200, so that the limiting block 310 passes through the notch 220 and slides along the first clearance surface 231 into the slide groove 210. In the connected state, the locking block 320 engages with the slot 110, and the blocking block 230 is also used to prevent the limiting block 310 from leaving the slide groove 210 on its own.

[0038] It should be noted that the first wire group and the second wire group respectively include an electrical connection wire and a signal wire, so as to realize the transmission of electricity and signal through the plugging and connection of the first connector and the second connector. In this embodiment, the slot 110 is provided on the outer wall of the first connector 100, and the locking block 320 is provided on the inner wall of the locking sleeve 300, and cooperates with the slot 110 to lock together, so as to prevent the first connector 100 from automatically disengaging from the second connector 200.

[0039] In the specific implementation process, the outer wall of the second connector 200 is provided with a groove 210 and a notch 220. It can be understood that the notch 220 is located on one side of the groove 210 and communicates with the groove 210. The limiting block 310 slides into the groove 210 from the notch 220 to achieve installation. Specifically, a blocking block 230 is also provided in the groove 210. The blocking block 230 is used to prevent the limiting block 310 from automatically disengaging from the groove 210, thereby ensuring the connection stability between the locking sleeve 300 and the second connector 200. Furthermore, the blocking block 230 is adjacent to the notch 220, and the top surface of the blocking block 230 is inclined. Specifically, the end of the top surface of the blocking block 230 away from the slide groove 210 is close to the central axis of the second connector 200. In this way, the side wall of the blocking block 230 facing the slide groove 210 can prevent the limiting block 310 from leaving the slide groove 210, and can also avoid interference with the blocking block 230 entering the slide groove 210, thereby facilitating the assembly of the locking sleeve 300.

[0040] In this embodiment, the slide groove 210 extends circumferentially along the second connector 200. The locking sleeve 300 rotates, causing the limiting block 310 to slide along the slide groove 210, thereby allowing the locking block 320 to engage with and disengage from the slot 110. In the connected state, the locking block 320 engages with the slot 110 to prevent the first connector 100 and the second connector 200 from automatically disengaging. The locking block rotates in the opposite direction, causing the locking block 320 to disengage from the slot 110, allowing the first connector 100 and the second connector 200 to disengage.

[0041] This utility model's technical solution connects the first wire group and the second wire group by interlocking the first connector 100 and the second connector 200. The second connector 200 is provided with a groove 210 and a notch 220. A locking sleeve 300 is used to movably fit on the second connector 200. Specifically, when installing the locking sleeve 300, the locking sleeve 300 moves along the axial direction of the second connector 200, causing the limiting block 310 to pass through the notch 220 and slide along the first clearance surface 231 into the groove 210, thus facilitating the installation of the locking sleeve 300. When disassembling the locking sleeve 300, the sleeve is rotated to make the limiting block 310 slide towards the blocking block 230 and disengage from the groove 210, and then leave from the notch 220. The disassembly and assembly are convenient, and the subsequent locking effect is not affected after disassembly and assembly, ensuring the service life of the connector. It is also convenient to install and improves production assembly efficiency.

[0042] refer to Figure 1 and 2 As shown, in one embodiment, the second connector 200 is also connected to an elastic member 400. The end of the slide groove 210 opposite to the blocking block 230 is provided with a fixing block. One end of the elastic member 400 is connected to the fixing block, and the other end is used to press against the limiting block 310. The locking sleeve 300 rotates circumferentially along the second connector 200 to drive the limiting block 310 to slide along the slide groove 210 and squeeze the elastic member 400. The locking sleeve 300 has a locked state and an unlocked state. In the locked state, the elastic member 400 drives the locking sleeve 300 to rotate in the opposite direction so that the locking block 320 is engaged in the slot 110. In the unlocked state, the locking block 320 leaves the slot 110.

[0043] In practical implementation, the elastic element 400 can be configured as a spring or other compressible and resilient component. Taking a spring as an example, one end of the spring is connected to the fixing block to fix the spring. After the locking sleeve 300 is sleeved on the second connector 200, the other end of the spring abuts against the limiting block 310, and the limiting block 310 also slides in the groove 210. In this way, as the first connector 100 and the second connector 200 gradually approach and insert, the locking sleeve 300 rotates, causing the limiting block 310 to compress the spring. Then, under its own elastic force, the spring drives the locking sleeve 300 to rotate in the opposite direction through the limiting block 310, causing the locking block 320 to engage in the slot 110, thereby completing the locking. When unlocking, drive the locking sleeve 300 to rotate, causing the locking block 320 to leave the slot 110, and pull the first connector 100 or the second connector 200 to separate them.

[0044] In one embodiment, the limiting block 310 is also connected to a positioning block 330. The second connector 200 is provided with a positioning groove 240. The positioning groove 240 is provided with a first positioning surface 241 and a second positioning surface 242 that are arranged opposite to each other. The extending directions of the first positioning surface 241 and the second positioning surface 242 are consistent with the extending direction of the slide groove 210. The positioning groove 240 is connected to the slide groove 210. The locking sleeve 300 moves along the axial direction of the second connector 200, so that the positioning block 330 slides into the positioning groove 240 and slides along the positioning groove 240.

[0045] In the specific implementation process, the positioning block 330 and the limiting block 310 are integrally formed. The height of the positioning block 330 protruding from the inner wall of the cavity is less than the height of the limiting block 310 protruding from the cavity, so as to facilitate the installation of the locking sleeve 300 and avoid interference. The first positioning surface 241 and the second positioning surface 242 of the positioning block 330 groove are arranged opposite to each other, and the extension direction of the positioning groove 240 is located in the rotation direction of the locking sleeve 300. The rotation of the locking sleeve 300 drives the positioning block 330 to slide in the positioning groove 240. The first positioning surface 241 is used to prevent the positioning block 330 from continuing to slide and to prevent the limiting block 310 from over-compressing the spring and causing failure. The second positioning surface 242 is used to limit the sliding direction of the positioning block 330, so that when the locking sleeve 300 is installed, after the positioning block 330 passes through the notch 220, it rotates in the limited direction, causing the limiting block 310 to slide into the slide groove 210.

[0046] In one embodiment, the locking block 320 is provided with a first guide wall 321, and the slot 110 includes a guide groove 111 and a limiting groove 112 that are interconnected. The guide groove 111 is provided with a second guide wall 113. When switching from the unlocked state to the locked state, the first guide wall 321 slides along the second guide wall 113, and the elastic member 400 also drives the locking sleeve 300 to rotate so that the locking block 320 is engaged in the limiting groove 112.

[0047] In the specific implementation process, the locking block 320 protrudes towards the cavity, and the first guide wall 321 is one side wall of the locking block 320. The slot 110 is recessed on the outer wall of the first connector 100, and the guide groove 111 extends to the end of the first connector 100. During the insertion and connection of the first connector 100 and the second connector 200, the first guide wall 321 slides along the second guide wall 113, causing the locking sleeve 300 to rotate and compress the spring. When the first guide wall 321 leaves the second guide wall 113 and reaches the limiting groove 112, the locking sleeve 300 is driven to rotate in the opposite direction and reset under the elastic action of the spring, so that the locking block 320 enters the slot 110, thereby achieving locking. When unlocking, the locking sleeve 300 is rotated away from the slot 110 and the first connector 100 or the second connector 200 is pulled. In the specific implementation process, two sets of slide 210, limit block 310 and locking block 320 are respectively symmetrically provided to ensure the stability and balance of the connection between the first connector 100 and the second connector 200.

[0048] In practical implementation, to facilitate the rotation of the locking sleeve 300, two symmetrically arranged drive ears 340 are provided on the outer wall of the locking sleeve 300. The drive ears 340 are protruding to achieve the purpose of saving effort and facilitating driving. In addition, it is understandable that a greater driving force is required during the assembly and disassembly of the locking sleeve 300, and the arrangement of the drive ears 340 also facilitates the rotation of the locking sleeve 300 for assembly and disassembly.

[0049] refer to Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the first connector 100 is connected to a plurality of first signal pins 120 and two first power pins 130, and the second connector 200 is connected to a plurality of second signal pins 250 and two second power pins 260. The second connector 200 is provided with a second connecting portion 270, in which the second signal pins 250 and the second power pins 260 are disposed. The locking sleeve 300 is at least partially movably fitted on the second connecting portion 270. The first connector 100 is provided with a first connecting portion 140, in which a slot 141 is formed. A slot 110 is provided on the side wall of the first connecting portion 140. In the connected state, the first signal pins 120 are inserted into the second signal pins 250, the first power pins 130 are inserted into the second power pins 260, the second connecting portion 270 is inserted into the slot 141, and the locking sleeve 300 is fitted on the first connecting portion 140, with the first connecting portion 140 located between the locking sleeve 300 and the second connecting portion 270.

[0050] In this embodiment, the first wire group and the second wire group are connected for communication through the insertion of the first signal pin 120 and the second signal pin 250, and for power transmission through the insertion of the first power pin 130 and the second power pin 260. The first connecting part 140 and the second connecting part 270 are opposite to each other and inserted into each other. The portion of the locking sleeve 300 with the limiting block 310 is fitted around the outer periphery of the first connecting part 140 and engages with the slot 110 on the outer wall of the first connecting part 140. After the first connecting part 140 and the second connecting part 270 are inserted, the portion of the first connecting part 140 with the slot 141 is located between the second connecting part and the locking sleeve 300 to achieve a tight insertion. The first power terminal is a 6mm signal terminal, and the first signal terminal is a 1mm signal terminal.

[0051] In the specific implementation, the second power pin 260 is provided with a crown spring 261, the thickness of which is 0.25mm-0.3mm. The first power pin 130 protrudes and is inserted into the crown spring 261 of the second power pin 260, making contact with the crown spring 261 to achieve electrical connection. It should be noted that, due to the large number of power terminals and signal terminals, insertion and removal difficulties may occur. In this embodiment, the thickness of the crown spring 261 is made to 0.25mm-0.3mm to reduce insertion and removal resistance and facilitate the insertion and removal of the first connection terminal.

[0052] Furthermore, in this embodiment, there are eight first signal pins 120 and eight second signal pins 250, and two first power pins 130 and two second power pins 260. The eight first signal pins 120 and two second signal pins 250 are connected one-to-one to realize the transmission of different functional commands, and the first power pins 130 and two power pins 260 are connected one-to-one to realize the transmission of power.

[0053] In one embodiment, the second connection portion 270 includes a first region 271, a second region 272 and a third region 273, with a space between each pair of the three regions. A partition 160 is provided in the slot 141 and is inserted into the space. A second power pin 260 is provided in the first region 271, another power pin is provided in the second region 272, and eight second signal pins 250 are provided in the third region 273.

[0054] Specifically, the two second power pins 260 are separated, and simultaneously separated from the eight second signal pins 250. The power supply current is relatively large, preventing short circuits and potential hazards. Understandably, the first signal terminal and the first power terminal are also correspondingly separated.

[0055] In one embodiment, the second connecting part 270 is provided with a sealing ring 500, which also provides waterproofing when the first connecting part 140 is inserted into the second connecting part 270.

[0056] In one embodiment, the first connector 100 has a receiving groove 150 at the end opposite to the first connecting portion 140. The first wire group is electrically connected to the first signal pin 120 and the first power pin 130 respectively. The first wire group is also at least partially located within the receiving groove 150, and a sealing block is formed within the receiving groove 150 by potting sealant. Specifically, after the first wire group is electrically connected to the first power pin 130 and the first signal pin 120, sealant is potted into the first receiving groove 150 to achieve sealing and waterproofing.

[0057] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the inventive concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
