Description

Technical Field

[0001] The 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] As an important component for interconnecting the power system of new energy vehicles, connectors are related to the safety and reliability of vehicles during driving. Among them, corner connectors are widely used in new energy vehicles because they can make the plug-in direction different from the extension direction of the cable and are suitable for compact wiring spaces. However, as people's requirements for the performance of new energy vehicles gradually increase, the performance of traditional corner connectors must also be gradually improved to adapt to this trend.

[0003] CPA (secondary locking structure) and HVIL (high voltage interlocking structure) are two more important structures on vehicle-mounted connectors. The former is used to ensure that the plug-in locking mechanism between the plug connector and the socket connector will not be easily unlocked, and to prevent the plug-in locking mechanism between the socket connector and the plug connector from failing due to factors such as vibration, thereby avoiding the plug-in failure of the plug connector and the socket connector. The latter is used to ensure that the signal circuit on the vehicle-mounted connector is turned on later than the power circuit and disconnected earlier than the power circuit, to prevent the vehicle-mounted connector from arcing and other damage during the plug-in and unplugging process.

[0004] The invention publication number CN111585103A Chinese invention patent application discloses a corner connector assembly, which adds a handle (i.e., a locking shell) to the socket of a traditional corner connector assembly. The handle is slidably mounted on the socket and cooperates with the plug through a lock slot (i.e., a guide linkage structure) and a lock column (i.e., a linkage matching structure), so that the sliding of the handle can drive the plug and the socket to be plugged in through the cooperation of the lock slot and the lock column. When the handle is pushed to the locking position, the plug connector and the socket connector begin to be plugged in under the linkage of the handle. After the handle is pushed in place, the plug connector and the socket connector also complete the plugging and locking between the two are achieved through the handle. At this time, the power circuit on the corner connector assembly is turned on. The corner connector assembly also includes a signal short-circuit component. After the handle is pushed in place, the insertion hole of the signal short-circuit component on the connector can be exposed. The signal short-circuit component is inserted into the insertion hole to conduct the signal circuit, and the position of the handle is locked and fixed to achieve the purpose of secondary locking. The above structure organically integrates 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 arrangement of the signal short-circuit component will cause the signal short-circuit component to be lost or accidentally damaged during assembly, and also complicate the plugging and mating operation of the connector assembly.

[0009] 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 portion in a downward direction and an escape position for leaving space under the end.

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 when plugging.

DETAILED DESCRIPTION

[0026] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0027] The principle of the connector assembly in the present invention is as follows:

[0028] A connector assembly, the structure of which can refer to Figure 1 As shown, it 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 shell 3. The connector body 4 is provided with a power terminal for plugging with the socket connector 2 to form a power circuit, and the locking shell 3 is slidably assembled on the connector body 4. The locking shell 3 can be referred to Figure 2 or Figure 3As shown, a guiding linkage structure is arranged thereon to cooperate with the linkage matching structure of the socket connector 2. Such a setting can drive the connector body 4 to be plugged in or disconnected with the socket connector 2 by sliding the locking housing 3 relative to the connector body 4.

[0029] In the present invention, the outer structure of the connector body 4 can refer to Figure 4 As shown, a signal terminal 5 for plugging with the socket connector 2 and forming a signal circuit is arranged inside. On this basis, the locking shell 3 has a complete locking position, an incomplete locking position and a complete separation position in its sliding stroke. When the locking shell 3 is in the complete locking position, the connector body 4 and the socket connector 2 are completely plugged in, and the signal terminals 5 and power terminals of both are kept in contact and form corresponding signal circuits and power circuits. When the locking shell 3 is in the incomplete locking position, the connector body 4 and the socket connector 2 are partially plugged in, and the signal terminals 5 of the two are disconnected and the signal circuit is disconnected. When the locking shell 3 is in the complete separation position, the connector body 4 and the socket connector 2 are completely disconnected, and the signal terminals 5 and power terminals of both are disconnected.

[0030] 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 the fully locked position and the incompletely locked position, so that the connector body 4 and the socket connector 2 can change from the fully plugged state to the incompletely plugged state, or from the incompletely plugged state to the fully plugged state; when the secondary lock of the secondary interlocking mechanism is unlocked, the locking housing 3 can slide between the incompletely locked position and the completely separated position, so that the connector body 4 and the socket connector 2 can change from the incompletely plugged state to the fully disengaged state, or from the fully disengaged state to the incompletely plugged state, thereby meeting the needs of high-voltage interlocking.

[0031] In the above structure, the signal terminal 5 is always located on the connector body 4, which reduces the number of components and does not cause the risk of loss or accidental damage due to the separate arrangement of the signal terminal 5. When performing the plug-in operation, the high-voltage interlocking requirement can be met by simply moving the locking housing 3 so that the locking housing 3 is locked in the desired position under the action of the secondary interlocking mechanism, and the operation is simple. Therefore, the connector assembly using the above high-voltage interlocking corner connector 1 is easy to perform the plug-in operation.

[0032] Based on the above-mentioned principle, the embodiment 1 of the connector assembly of the present invention is:

[0033] A connector assembly, the structure of which can refer to Figure 1As shown, it 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 shell 3. The connector body 4 is provided with a power terminal for connecting with the socket connector 2 and forming a power circuit, and the locking shell 3 is slidably assembled on the connector body 4. The specific structure of the locking shell 3 can be referred to Figure 2 or Figure 3 As shown, a guide linkage structure is provided thereon so as 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 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 elaboration is required.

[0034] The appearance and structure of the connector body 4 can be referred to Figure 4As shown, a signal terminal 5 for connecting with the socket connector 2 and forming a signal circuit is arranged inside. On this basis, the locking housing 3 has a complete locking position, an incomplete locking position and a complete separation position in its sliding stroke. Since the conduction position of the signal terminal 5 is later than the conduction position of the power terminal, and the electrical contact length between the power terminal and the power terminal on the socket connector 2 is longer than the electrical contact length between the signal terminal 5 and the signal terminal 5 on the socket connector 2, when the connector assembly is plugged in, the power terminal can achieve electrical contact and conduct the power circuit before the signal terminal 5; when the connector assembly is separated, the power terminal can be disconnected from the electrical contact later than the signal terminal 5, so that the power circuit is disconnected later than the signal circuit. When the locking housing 3 is in the complete locking 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 housing 3 is in the incomplete locking position, the connector body 4 is partially plugged in with the socket connector 2, and the signal terminals 5 of both are disconnected to disconnect the signal circuit. When the locking shell 3 is in the completely 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 the fully engaged state to the incompletely engaged state, or from the incompletely engaged state to the 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 completely separated position, so that the connector body 4 and the socket connector 2 can change from the incompletely engaged state to the fully disengaged state, or from the fully disengaged state to the incompletely engaged state, thereby meeting the needs of high-voltage interlocking. The above structure enables the signal terminal 5 to always be located on the connector body 4, reduces the number of components, and does not cause the risk of loss or accidental damage due to the separate arrangement of the signal terminal 5, and also simplifies the plugging operation of the connector assembly.

[0035] The key point of this embodiment is that Figure 5 , Figure 6As shown, the secondary interlocking mechanism includes a locking rocker 8 rotatably arranged on the locking housing 3, and a primary lock 9 and a secondary lock 10 arranged on the connector body 4 and arranged along the sliding direction of the locking housing 3. A primary lock hook 11 that can be hooked and matched with the primary lock 9 is provided on the lower side surface of one end of the locking rocker 8 facing the connector plug-in part, and a secondary lock hook 12 that can be hooked and matched with the secondary lock 10 is provided on the lower side surface of the other end. When the high-voltage interlocking angle connector 1 is plugged into the socket connector 2, the primary lock hook 11 releases the hooking and matching with the primary lock when the locking rocker 8 swings upward, and the secondary lock hook 12 releases the hooking and matching with the secondary lock when it swings downward. In this embodiment, the specific structure of the secondary interlocking mechanism can refer to the technical solution disclosed in the Chinese invention application with the invention publication number CN111641077A, that is, the locking seesaw 8 can specifically adopt the locking plate structure described in the invention application, and can be rotatably assembled on the locking housing 3 through an axis arranged perpendicular to the sliding direction of the slider of the locking housing 3, so that when one end of the locking seesaw 8 rotates close to the locking housing 3, the other end can be synchronously rotated and away from the locking housing 3. The primary lock hook 11 and the secondary lock hook 12 on the locking seesaw 8 can specifically refer to the primary lock hook 11 and the secondary lock hook 12 on the locking plate described in the invention application, and the primary lock buckle 9 and the secondary lock buckle 10 on the connector body 4 can specifically refer to the primary lock buckle and the secondary lock buckle on the socket connector 2 in the invention application, so that the locking housing 3 and the connector body 4 can have a double locking effect as the plug connector and the socket connector 2 described in the invention application.

[0036] like Figure 5As shown, when the high-voltage interlocking corner connector 1 and the socket connector 2 are plugged into place, the primary lock hook 11 and the primary lock buckle 9 are hooked and matched with each other to keep the locking housing 3 in the fully locked position. At this time, the power terminal and the signal terminal 5 in the high-voltage interlocking corner connector 1 are respectively electrically contacted with the power terminal and the signal terminal 5 in the socket connector 2, so that both the power circuit and the signal circuit are conductive. When pulling out, first press the end of the locking rocker 8 facing away from the connector plug-in part to disengage the primary lock hook 11 from the primary lock buckle 9, and the locking housing 3 can move from the fully locked position to the incompletely locked position. When the locking housing 3 moves from the fully locked position to the incompletely locked position, the guide groove 6 on the locking housing 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 fully plugged state to the incompletely plugged state, and the signal terminal 5 is first disengaged from the electrical contact to disconnect the signal circuit. At this time, the secondary lock hook 12 and the secondary lock buckle 10 are hooked and matched with each other to keep the locking housing 3 in the incomplete locking position. When continuing to pull out, first press the end of the locking rocker 8 toward the connector plug-in part to disengage the secondary lock hook 12 from the secondary lock buckle 10, and the locking housing 3 can move from the incomplete locking position to the complete separation position. When the locking housing 3 moves from the incomplete locking position to the complete separation position, the high-voltage interlocking corner connector 1 and the socket connector 2 also change from the incomplete plug-in state to the complete disengagement state through the linkage of the guide groove 6 on the locking housing 3 and the guide ear column 7 on the socket connector 2, 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 only needs to control the locking rocker 8 to control the segmented movement of the locking housing 3, thereby achieving the technical purpose of making the signal circuit and the power circuit on the connector assembly disconnect in steps according to the high-voltage interlocking requirements, which greatly simplifies the operation of the connector assembly when plugging and disconnecting.

[0037] It is easy to think that the aforementioned secondary interlocking mechanism can also be a first spring claw and a second spring claw arranged on the connector body 4 and along the sliding direction of the locking shell 3, and a buckle window arranged on the locking shell 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 buckle window are snapped with each other to keep the locking shell 3 in the fully locked position. At this time, the power terminal and the signal terminal 5 in the high-voltage interlocking corner connector 1 are respectively electrically contacted with the power terminal and the signal terminal 5 in the socket connector 2, so that the power circuit and the signal circuit are both turned on. When pulling out, press the first spring claw from the buckle window to force it to retreat, so that the first spring claw and the buckle window are disengaged, and the locking shell 3 can move from the fully locked position to the incompletely locked position. When the locking housing 3 moves from the fully locked position to the incompletely locked position, the guide groove 6 on the locking housing 3 and the guide ear column 7 on the socket connector 2 are linked and cooperated, and the high-voltage interlocking corner connector 1 and the socket connector 2 also change from the fully plugged state to the incompletely plugged state, and the signal terminal 5 is first disengaged from the electrical contact to disconnect the signal circuit. At this time, the second buckle claw and the buckle window are mutually engaged to keep the locking housing 3 in the incompletely locked position. When continuing to pull out, continue to press the second spring claw from the buckle window to force it to retreat, so that the second spring claw and the buckle window are disengaged, and the locking housing 3 can be moved from the incompletely locked position to the completely separated position. When the locking housing 3 moves from the incompletely locked position to the completely disengaged position, the guide groove 6 on the locking housing 3 and the guide ear column 7 on the socket connector 2 are linked and cooperated, and the high-voltage interlocking corner connector 1 and the socket connector 2 also change from the incompletely plugged state to the completely disengaged state, and the power terminal is disengaged from the electrical contact to disconnect the power circuit.

[0038] Based on the above-mentioned principle and embodiment 1, embodiment 2 of the connector assembly of the present invention is:

[0039] Compared with the first embodiment, the key point of the present embodiment is that the secondary interlocking mechanism further includes a locking block 13 slidably mounted on the locking housing 3. Figure 7 , Figure 8 As shown, the locking block 13 has a stop position for blocking the end of the locking rocker 8 facing away from the connector plug-in part in the downward direction and a evasion position for leaving space under the end within its movement range. The locking block 13 is inserted under the end of the locking rocker 8 facing away from the connector plug-in part when the connector assembly is fully plugged in to prevent the end from moving downward, 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 being disengaged due to misoperation of the locking rocker 8, and effectively ensuring the reliability of the plug-in of the connector assembly.

[0040] Based on the above structure, Figure 7 , Figure 8As shown, the locking block 13 may be provided with a barb 14 on one side facing the locking housing 3. The barb 14 has a straight surface on one side facing the insertion direction of the locking block 13, and a curved surface connected to the straight surface on the other side. The locking housing 3 is provided with a corresponding boss 15 on one side facing the locking block 13, and the boss 15 is provided with a straight surface on the side facing away from the insertion direction of the locking block 13, so as to cooperate with the barb 14 when the locking block 13 slides from the avoidance position to the blocking position, so as to prevent 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 aforementioned inclined surface and the curved surface. Of course, the aforementioned inclined surface and the curved surface can also be interchangeable, or they can be both inclined surfaces, or they can be both curved surfaces, which will not be repeated here.

[0041] On this basis, the locking block 13 may be provided with a sliding portion, and the locking housing 3 and / or the connector body 4 may 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 housing 3 and a second lifting portion 19 provided on the connector body 4. The first lifting portion 18 is provided on the locking housing 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 arc head 16 and the barb 14 can smoothly slide over the top portion under the guidance of the arc surface of the first top portion 18, until the straight surface of the barb 14 and the straight surface of the boss 15 are blocked and matched to prevent 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 are blocked and matched to prevent the locking block 13 from slipping out. The second top portion 19 is provided with an inclined surface on one side facing and 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 external force, the inclined surface of the second top portion 19 cooperates with the arc surface of the arc head 16 to lift the locking block 13 and make the barb 14 and the boss 15 disengage from the blocking cooperation. The locking block 13 can be provided with a stop surface 20 in place to stop and match with the straight surface of the boss 15 after the locking block 13 slides to the stop position to prevent 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 on the side 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 make the blocking surface 20 and the boss 15 disengage from the blocking cooperation. At this time, the locking block 13 can continue to slide to the avoidance position. Such a setting can make the locking block 13 have a clear position 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.

[0042] Of course, the first protruding portion 18 and the second protruding portion 19 can both be provided on the locking housing 3, or only the second protruding portion 19 can be provided on the connector body 4. On this basis, it is easy to imagine that when the cost is limited, the locking block 13 can also include only its block body. The locking block 13 is kept in the blocking position or the avoidance position by friction. Based on this, the locking block 13 is preferably made of a material with a large friction coefficient, such as rubber.

[0043] The parts not mentioned in this embodiment are consistent with those in Embodiment 1.
