Description

A high-voltage interlocking corner connector and connector assembly Technical Field

[0001] The present invention belongs to the field of electrical connectors, and in particular relates to a high-voltage interlocking corner connector and a connector assembly. Background Art

[0002] Connectors, as crucial interconnect components for the powertrains of new energy vehicles, are crucial for vehicle safety and reliability. Angled connectors, which allow for insertion in a direction different from the cable's extension, are widely used in new energy vehicles because they accommodate compact wiring spaces. However, as performance requirements for new energy vehicles continue to rise, the performance of traditional angular connectors must also be improved to accommodate this trend.

[0003] CPA (Secondary Locking Arrangement) and HVIL (High Voltage Interlocking Arrangement) are two of the most important structures in automotive connectors. The former is used to ensure that the locking mechanism between the plug and receptacle connectors will not be easily unlocked, preventing the locking mechanism between the receptacle and plug connectors from failing due to factors such as vibration, thereby avoiding the plug and receptacle connector from failing. The latter is used to ensure that the signal circuit on the automotive connector is connected later than the power circuit and disconnected earlier than the power circuit, preventing damage such as arcing during the plug and unplug process.

[0004] A Chinese invention patent application, publication number CN111585103A, discloses a corner connector assembly that adds a handle (i.e., a locking housing) to the socket of a conventional corner connector assembly. The handle is slidably mounted on the socket and engages with the plug via a lock slot (i.e., a guide linkage structure) and a lock post (i.e., a linkage engagement structure), so that the sliding of the handle can drive the plug and socket to engage through the engagement of the lock slot and the lock post. When the handle is pushed toward the locking position, the plug connector and the socket connector begin to engage in conjunction with the handle. After the handle is pushed into place, the plug connector and the socket connector also simultaneously complete engagement, and the handle achieves a locking engagement between the two. At this point, the power circuit on the corner connector assembly is energized. The corner connector assembly also includes a signal shorting component. When the handle is pushed into place, the insertion hole for the signal shorting component on the connector is exposed. The signal shorting component is inserted into the insertion hole to energize the signal circuit, while simultaneously locking the handle in place to achieve a secondary locking function. The above structure organically integrates the CPA and HVIL into the corner connector, effectively improving the performance of the corner connector. However, this structure involves many components, which is not conducive to processing and production. The separate provision of the signal shorting component will increase the risk of loss or accidental damage during assembly, and also complicate the plugging and mating operation of the connector assembly.

[0006] The purpose of the present invention is to provide a high-voltage interlocking corner connector to solve the technical problem that the existing corner connector with CPA and HVIL involves many components and is not convenient for plugging with the adapter connector; the purpose of the present invention is also to provide a connector assembly to solve the technical problem that the corner connector assembly with CPA and HVIL is not convenient for plugging and unplugging operations.

[0007] The present invention adopts the following technical solutions:

[0009] Furthermore, the secondary interlocking mechanism includes a locking seesaw rotatably arranged on the locking shell, and a primary lock and a secondary lock arranged on the connector body and arranged along the sliding direction of the locking shell; the lower side surface of one end of the locking seesaw facing the connector plug-in part is provided with a primary lock hook that can be hooked and matched with the primary lock, and the lower side surface of the other end is provided with a secondary lock hook that can be hooked and matched with the secondary lock; the primary lock hook is released from the hooking cooperation with the primary lock when the locking seesaw swings upward, and the secondary lock hook is released from the hooking cooperation with the secondary lock when it swings downward.

[0010] Furthermore, the secondary interlocking mechanism also includes a locking block slidably mounted on the locking housing, and the locking block has a blocking position within its movement range for blocking the end of the locking rocker facing away from the connector plug-in part in the downward direction and an avoidance position for leaving space under the end.

[0011] Furthermore, a barb is provided on the lower side of the locking block, and a boss is provided on the locking shell that cooperates with the barb to prevent the locking block from sliding from the avoidance position to the blocking position; a sliding jump portion is provided on the locking block, and a lifting portion is provided on the locking shell and / or the connector body, and the lifting portion can cooperate with the sliding jump portion when the locking block slides from the avoidance position to the blocking position to lift the locking block and disengage the barb from the boss.

[0012] Beneficial effects: The present invention improves the existing corner connector with CPA and HVIL, and specifically proposes a high-voltage interlocking corner connector. The high-voltage interlocking corner connector includes a connector body and a locking shell, wherein the connector body is provided with power terminals for plugging with the adapter connector and forming a power circuit, and the locking shell is slidably assembled on the connector body. A guide linkage structure is provided on the locking shell to cooperate with the linkage matching structure of the adapter connector. Such a setting can drive the connector body and the adapter connector to be plugged in or disconnected by sliding the locking shell relative to the connector body. The key point of the present invention is that the connector body is provided with signal terminals for plugging with the adapter connector and forming a signal circuit.

In the above structure, the signal terminal is always located on the connector body, which reduces the number of components while also not causing the risk of loss or accidental damage due to the separate arrangement of the signal terminal. When performing the plugging operation, it is only necessary to move the locking shell so that the locking shell is locked in the required position under the action of the secondary interlocking mechanism to meet the high-voltage interlocking requirements. The operation is simple and is conducive to improving the plugging efficiency of the connector.

DETAILED DESCRIPTION

[0027] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0028] The principle of the connector assembly in the present invention is as follows:

[0029] A connector assembly, the structure of which can be seen with reference to FIG1 , includes a high-voltage interlocking angle connector 1 and a receptacle connector 2. The high-voltage interlocking angle connector 1 includes a connector body 4 and a locking housing 3. The connector body 4 is provided with power terminals for mating with the receptacle connector 2 to form a power circuit, and the locking housing 3 is slidably assembled onto the connector body 4. The locking housing 3, as shown in FIG2 or FIG3 , is provided with a guide linkage structure to mate with the linkage mating structure of the receptacle connector 2. This arrangement allows the connector body 4 to be mated or disconnected with the receptacle connector 2 by sliding the locking housing 3 relative to the connector body 4.

[0030] In the present invention, the external structure of the connector body 4 can be referred to as shown in FIG4 , and a signal terminal 5 for plugging in with the socket connector 2 and forming a signal circuit is provided inside the connector body 4. On this basis, the locking shell 3 has a fully locked position, an incompletely locked position, and a fully separated position in its sliding stroke. When the locking shell 3 is in the fully locked position, the connector body 4 is fully plugged in with the socket connector 2, and the signal terminals 5 and power terminals of both are in contact and form corresponding signal circuits and power circuits. When the locking shell 3 is in the incompletely locked position, the connector body 4 is partially plugged in with the socket connector 2, and the signal terminals 5 of both are disconnected and the signal circuit is disconnected. When the locking shell 3 is in the fully separated position, the connector body 4 is completely disconnected from the socket connector 2, and the signal terminals 5 and power terminals of both are disconnected.

[0031] A secondary interlocking mechanism is provided between the connector body 4 and the locking housing 3. When the primary lock of the secondary interlocking mechanism is unlocked, the locking housing 3 can slide between a fully locked position and an incompletely locked position, so that the connector body 4 and the receptacle connector 2 can change from a fully engaged state to an incompletely engaged state, or from an incompletely engaged state to a fully engaged state; when the secondary lock of the secondary interlocking mechanism is unlocked, the locking housing 3 can slide between an incompletely locked position and a completely separated position, so that the connector body 4 and the receptacle connector 2 can change from an incompletely engaged state to a fully disengaged state, or from a fully disengaged state to an incompletely engaged state, thereby meeting the requirements of high-voltage interlocking.

[0032] In the above structure, the signal terminals 5 are always located on the connector body 4, reducing the number of components while also eliminating the risk of loss or accidental damage caused by the separate placement of the signal terminals 5. During the mating operation, the high-voltage interlock requirement is satisfied simply by moving the locking housing 3 and locking it in the desired position under the action of the secondary interlocking mechanism. Therefore, connector assemblies using the above-described high-voltage interlocking angle connector 1 are easy to mate and mate.

[0033] Based on the above-mentioned principle, the embodiment 1 of the connector assembly of the present invention is:

[0034] A connector assembly, the structure of which can be referred to as FIG1 , includes a high-voltage interlocking angle connector 1 and a socket connector 2. The high-voltage interlocking angle connector 1 includes a connector body 4 and a locking housing 3. The connector body 4 is provided with power terminals for connecting with the socket connector 2 and forming a power circuit, and the locking housing 3 is slidably assembled on the connector body 4. The specific structure of the locking housing 3 can be referred to as FIG2 or FIG3 , and is provided with a guide linkage structure to cooperate with the linkage matching structure of the socket connector 2. In this embodiment, the guide linkage mechanism is specifically a guide groove 6 provided on the locking housing 3, and the linkage matching structure is a guide ear column 7 provided on the socket connector 2. The guide groove 6 is specifically an oblique groove or an arc-shaped groove, and is guided and slidably matched with the guide ear column 7, so that the sliding of the locking housing 3 relative to the connector body 4 can drive the connector body 4 and the socket connector 2 to move in the plugging direction, thereby realizing the mutual plugging or disconnection of the connector body 4 and the socket connector 2. The above-mentioned guide linkage mechanism and linkage matching structure are consistent with the prior art, so no further details are given.

[0035] The connector body 4, as shown in Figure 4, houses signal terminals 5 for connecting with the receptacle connector 2 and forming a signal circuit. The locking housing 3 has three positions during its sliding travel: a fully locked position, a partially locked position, and a fully disengaged position. Because the signal terminals 5 are positioned later than the power terminals, and the electrical contact length between the power terminals and the power terminals on the receptacle connector 2 is longer than the electrical contact length between the signal terminals 5 and the signal terminals 5 on the receptacle connector 2, the power terminals can establish electrical contact and establish the power circuit before the signal terminals 5 when the connector assemblies are mated. When the connector assemblies are disengaged, the power terminals can disengage electrical contact after the signal terminals 5, disconnecting the power circuit after the signal circuit. When the locking housing 3 is in the fully locked position, the connector body 4 is fully mated with the receptacle connector 2, and the signal terminals 5 and power terminals on both maintain contact, forming corresponding signal and power circuits. When the locking housing 3 is in the partially locked position, the connector body 4 is partially mated with the receptacle connector 2, and the signal terminals 5 on both disengage, disconnecting the signal circuit. When the locking shell 3 is in the fully separated position, the connector body 4 and the socket connector 2 are completely disengaged, and the signal terminals 5 of both are disconnected from the power terminals. A secondary interlocking mechanism is also provided between the connector body 4 and the locking shell 3. When the primary lock of the secondary interlocking mechanism is unlocked, the locking shell 3 can slide between the fully locked position and the incompletely locked position, so that the connector body 4 and the socket connector 2 can change from a fully engaged state to an incompletely engaged state, or from an incompletely engaged state to a fully engaged state; when the secondary lock of the secondary interlocking mechanism is unlocked, the locking shell 3 can slide between the incompletely locked position and the fully separated position, so that the connector body 4 and the socket connector 2 can change from an incompletely engaged state to a fully disengaged state, or from a fully disengaged state to an incompletely engaged state, thereby meeting the needs of high-voltage interlocking. The above structure allows the signal terminals 5 to always be located on the connector body 4, reducing components while also not risking loss or accidental damage due to the separate arrangement of the signal terminals 5. It also simplifies the plugging operation of the connector assembly.

[0036] The key point of this embodiment is that, as shown in Figures 5 and 6, the secondary interlocking mechanism includes a locking rocker 8 that is rotatably mounted on the locking housing 3, and a primary lock catch 9 and a secondary lock catch 10 that are mounted on the connector body 4 and arranged along the sliding direction of the locking housing 3. A primary lock hook 11 that engages with the primary lock catch 9 is provided on the lower side of the locking rocker 8 at one end facing the connector plug-in portion, and a secondary lock hook 12 that engages with the secondary lock catch 10 is provided on the lower side of the other end. When the high-voltage interlocking corner connector 1 is mated with the receptacle connector 2, the primary lock hook 11 releases its engagement with the primary lock catch as the locking rocker 8 swings upward, and the secondary lock hook 12 releases its engagement with the secondary lock catch as it swings downward. In this embodiment, the specific structure of the secondary interlocking mechanism can refer to the technical solution disclosed in Chinese invention application publication number CN111641077A. That is, the locking seesaw 8 can specifically adopt the locking plate structure described in that invention application and can be rotatably assembled to the locking housing 3 via an axis arranged perpendicular to the sliding direction of the slider of the locking housing 3. This allows one end of the locking seesaw 8 to rotate toward the locking housing 3 while the other end can synchronously rotate away from the locking housing 3. The primary locking hook 11 and secondary locking hook 12 on the locking seesaw 8 can specifically refer to the primary locking hook 11 and secondary locking hook 12 on the locking plate described in that invention application. The primary locking catch 9 and secondary locking catch 10 on the connector body 4 can specifically refer to the primary locking catch and secondary locking catch on the receptacle connector 2 described in that invention application. This allows the locking housing 3 and the connector body 4 to achieve a double locking effect, similar to the plug connector and receptacle connector 2 described in that invention application.

[0037] As shown in Figure 5, when the high-voltage interlocking corner connector 1 and the receptacle connector 2 are fully engaged, the primary locking hook 11 and the primary locking catch 9 engage with each other, maintaining the locking housing 3 in the fully locked position. The power terminals and signal terminals 5 in the high-voltage interlocking corner connector 1 are now in electrical contact with the power terminals and signal terminals 5 in the receptacle connector 2, respectively, ensuring that both the power and signal circuits are conductive. To remove the connector, first press the end of the locking rocker 8 facing away from the connector insertion area to disengage the primary locking hook 11 from the primary locking catch 9. This allows the locking housing 3 to move from the fully locked position to the partially locked position. When the locking housing 3 moves from the fully locked position to the partially locked position, the guide slots 6 on the locking housing 3 and the guide ears 7 on the receptacle connector 2 interact, causing the high-voltage interlocking corner connector 1 and the receptacle connector 2 to transition from a fully engaged state to a partially engaged state, with the signal terminals 5 first disengaging electrically to disconnect the signal circuit. At this time, the secondary lock hook 12 and the secondary lock catch 10 are hooked and matched with each other to keep the locking shell 3 in the incomplete locking position. When continuing to pull out, first press the locking rocker 8 towards one end of the connector plug-in part to disengage the secondary lock hook 12 from the secondary lock catch 10. At this time, the locking shell 3 can move from the incomplete locking position to the completely separated position. When the locking shell 3 moves from the incomplete locking position to the completely disengaged position, the guide groove 6 on the locking shell 3 and the guide ear column 7 on the socket connector 2 are linked and matched, and the high-voltage interlocking corner connector 1 and the socket connector 2 also change from the incomplete plug-in state to the completely disengaged state, and the power terminal is disconnected from the electrical contact to disconnect the power circuit. The above structure simplifies the technical solution of the secondary locking, so that when the connector assembly is plugged in and out, it is only necessary to control the locking rocker 8 to control the segmented movement of the locking shell 3, thereby achieving the technical purpose of making the signal circuit and the power circuit on the connector assembly connected and disconnected in steps according to the high-voltage interlocking requirements, greatly simplifying the operation of plugging and disconnecting the connector assembly.

[0038] It is easy to imagine that the aforementioned secondary interlocking mechanism can also be a first spring claw and a second spring claw provided on the connector body 4 and arranged along the sliding direction of the locking housing 3, as well as a snap-fit ​​window provided on the locking housing 3 for snapping with the first spring claw and the second spring claw. When the high-voltage interlocking corner connector 1 and the socket connector 2 are plugged into place, the first spring claw and the snap-fit ​​window snap-fit ​​with each other to keep the locking housing 3 in the fully locked position. At this time, the power terminals and signal terminals 5 in the high-voltage interlocking corner connector 1 are electrically contacted with the power terminals and signal terminals 5 in the socket connector 2, respectively, so that both the power circuit and the signal circuit are conductive. When unplugging, the first spring claw is pressed from the snap-fit ​​window to force it back, so that the first spring claw and the snap-fit ​​window are disengaged, and the locking housing 3 can now move from the fully locked position to the partially locked position. When the locking housing 3 moves from the fully locked position to the partially locked position, the guide slots 6 on the locking housing 3 and the guide lugs 7 on the receptacle connector 2 interact, causing the high-voltage interlocking corner connector 1 and receptacle connector 2 to transition from a fully engaged state to a partially engaged state. This causes the signal terminals 5 to first break electrical contact, disconnecting the signal circuit. At this point, the second latch engages with the latch window, maintaining the locking housing 3 in the partially locked position. To continue removing the locking housing 3, the second spring claw is further pressed from within the latch window, forcing it back and disengaging it. This allows the locking housing 3 to move from the partially locked position to the fully disengaged position. When the locking housing 3 moves from the partially locked position to the fully disengaged position, the guide slots 6 on the locking housing 3 and the guide lugs 7 on the receptacle connector 2 interact, causing the high-voltage interlocking corner connector 1 and receptacle connector 2 to transition from a partially engaged state to a fully disengaged state. This causes the power terminals to break electrical contact, disconnecting the power circuit.

[0039] Based on the above-mentioned principle and embodiment 1, embodiment 2 of the connector assembly of the present invention is as follows:

[0040] Compared with Example 1, the key point of this embodiment is that the secondary interlocking mechanism also includes a locking block 13 slidably mounted on the locking housing 3. As shown in Figures 7 and 8, the locking block 13 has a blocking position for blocking the end of the locking rocker 8 facing away from the connector plug-in part in the downward direction within its movement range, and an escape position for clearing the space below this end. When the connector assembly is fully plugged in, the locking block 13 is inserted under the end of the locking rocker 8 facing away from the connector plug-in part to prevent the downward movement of this end, thereby keeping the primary lock hook 11 and the primary lock buckle 9 locked at all times, preventing the primary lock hook 11 and the primary lock buckle 9 from disengaging due to misoperation of the locking rocker 8, and effectively ensuring the reliability of the connector assembly.

[0041] Based on the above structure, as shown in Figures 7 and 8, the locking block 13 can be provided with a barb 14 on the side facing the locking housing 3. The barb 14 has a straight surface on the side facing the insertion direction of the locking block 13 and a curved surface on the other side that connects to the straight surface. The locking housing 3 is provided with a corresponding boss 15 on the side facing the locking block 13. The boss 15 has a straight surface on the side facing away from the insertion direction of the locking block 13 so that it can block and cooperate with the barb 14 when the locking block 13 slides from the avoidance position to the blocking position, thereby preventing the movement of the locking block 13. The other side of the boss 15 is provided with an inclined surface so that when the locking block 13 moves from the blocking position to the avoidance position, the barb 14 can slide over the boss 15 through the guidance of the inclined surface and the curved surface. Of course, the inclined surface and the curved surface can also be interchangeable, or can be both inclined surfaces or both curved surfaces, which will not be repeated here.

[0042] On this basis, the locking block 13 can be provided with a sliding portion, and the locking shell 3 and / or the connector body 4 can be provided with a lifting portion. In this embodiment, the sliding portion specifically includes an arc-shaped head 16 located on the locking block 13 at one end facing the insertion direction thereof, and an arc-shaped tail 17 located on the locking block 13 at one end facing away from the insertion direction thereof. The arc-shaped head 16 has arc surfaces on both sides facing and away from the insertion direction of the locking block 13, and the arc-shaped tail 17 has an arc surface on one side facing the insertion direction of the locking block 13 and a straight surface on the other side. The lifting portion includes a first lifting portion 18 provided on the locking shell 3 and a second lifting portion 19 provided on the connector body 4. The first lifting portion 18 is provided on the locking shell 3, and specifically includes a straight surface facing the insertion direction of the locking block 13 and an arc surface arranged on the other side. When the locking block 13 is inserted, the arcuate head 16 and the barb 14 can smoothly slide over the top portion under the guidance of the arcuate surface of the first top portion 18 until the straight surface of the barb 14 and the straight surface of the boss 15 stop and cooperate, thereby preventing the locking block 13 from sliding from the avoidance position to the stop position. The straight surface of the first top portion 18 and the straight surface of the ski jump tail stop and cooperate to prevent the locking block 13 from slipping out. The second top portion 19 is provided with an inclined surface on both the side facing and the side facing away from the insertion direction of the locking block 13. When the locking block 13 slides from the avoidance position to the stop position under the action of an external force, the inclined surface of the second top portion 19 cooperates with the arcuate surface of the arcuate head 16 to lift the locking block 13 and disengage the barb 14 from the stop and cooperate. The locking block 13 can be provided with a stop surface 20 to stop and cooperate with the straight surface of the boss 15 after the locking block 13 slides to the stop position, thereby preventing the locking block 13 from sliding further. When the locking block 13 slides from the blocking position to the avoidance position, the arc surface of the arc head 16 facing away from the insertion direction of the locking block 13 cooperates with the second lifting portion 19 to lift the locking block 13 and disengage the blocking engagement between the positioning stop surface 20 and the boss 15. At this time, the locking block 13 can continue to slide to the avoidance position. This arrangement can ensure that the locking block 13 has a clear positional relationship with the locking housing 3, thereby ensuring that the locking block 13 can be stably maintained in its blocking position or avoidance position to ensure its blocking or avoidance function.

[0043] Of course, both the first and second protruding portions 18, 19 can be provided on the locking housing 3, or only the second protruding portion 19 can be provided on the connector body 4. Based on this, it is readily conceivable that, if costs are limited, the locking block 13 can also consist solely of its body. The locking block 13 is maintained in the blocking or avoiding position by friction. Therefore, the locking block 13 is preferably made of a material with a high friction coefficient, such as rubber.

[0044] The parts not mentioned in this embodiment are consistent with those in Example 1.
