Description

High-voltage interlocking corner connector and connector assembly

Technical Field

The invention belongs to the field of electric connectors, and particularly relates to a high-voltage interlocking corner connector and a connector assembly.

Background

The connector is used as an important part of the power system interconnection of the new energy automobile, and safety and reliability of the automobile in the running process are concerned. The corner connector is applicable to a compact wiring space because the plugging direction is different from the extending direction of the cable, and therefore, the corner connector has extremely wide application in new energy automobiles. However, as the performance of new energy automobiles increases, the performance of conventional corner connectors must also increase to accommodate this trend.

CPA (secondary locking structure) and HVIL (high voltage interlocking structure) are two structures which are important on the existing vehicle-mounted connector, the former is used for ensuring that a plugging locking mechanism between a plug connector and a socket connector cannot be unlocked easily, preventing the plugging locking mechanism between the socket connector and the plug connector from being invalid due to factors such as vibration and the like, and further avoiding the situation that the plugging of the plug connector and the socket connector is invalid. The signal loop on the vehicle-mounted connector is guaranteed to be conducted later than the power loop, and is disconnected earlier than the power loop, so that damage conditions such as arc discharge and the like of the vehicle-mounted connector in the plugging process are prevented.

Chinese patent application publication No. CN111585103a discloses a corner connector assembly in which a handle (i.e., a locking housing) is added to a socket of a conventional corner connector assembly. The handle is slidably arranged on the socket and is matched with the plug through a locking groove (namely a guide linkage structure) and a locking column (namely a linkage matching structure), so that the sliding of the handle can drive the plug to be inserted into the socket through the matching of the locking groove and the locking column. When the handle is pushed to the locking position, the plug connector and the socket connector start to be inserted under the linkage of the handle. After the handle is pushed in place, the plug connector and the socket connector are synchronously inserted, and the insertion locking between the plug connector and the socket connector is realized through the handle. At this point the power loop on the corner connector assembly is conductive. The corner connector assembly also includes a signal shorting member. The handle can expose the plug-in hole site of the signal shorting member on the connector after being pushed in place. The signal short circuit part is inserted into the inserting hole site to conduct the signal loop, and meanwhile, the position of the handle is locked and fixed to achieve the purpose of secondary locking. The structure organically integrates CPA and HVIL onto the corner connector, so that the service performance of the corner connector is effectively improved. However, this structure involves a large number of components, which is disadvantageous for processing and production. The separate arrangement of the signal shorting member may result in the risk of losing or accidentally damaging the signal shorting member during assembly, and may also complicate the mating operation of the connector assembly.

Detailed Description

The features and capabilities of the present invention are described in further detail below in connection with the examples.

The scheme principle of the connector assembly in the invention is as follows:

a connector assembly, the structure of which can be seen with reference to figure 1, comprises a high voltage interlocking corner connector 1 and a receptacle connector 2. Wherein the high-voltage interlock corner connector 1 comprises a connector body 4 and a locking housing 3. The connector body 4 is provided with power terminals for plugging with the receptacle connector 2 and forming a power circuit, and the lock housing 3 is slidably fitted to the connector body 4. The locking housing 3 may be referred to as shown in fig. 2 or 3, and is provided with a guide interlocking structure so as to cooperate with the interlocking mating structure of the receptacle connector 2. Such an arrangement may actuate the insertion or disconnection of the connector body 4 with the receptacle connector 2 by sliding the lock housing 3 relative to the connector body 4.

In the present invention, the connector body 4 has an external structure as shown in fig. 4, and is internally provided with a signal terminal 5 for plugging with the receptacle connector 2 and forming a signal circuit. On the basis of this, the locking housing 3 has a full locking position, an incomplete locking position and a full release position in its sliding travel. When the locking housing 3 is in the fully locked position, the connector body 4 and the receptacle connector 2 are fully plugged together, and the signal terminals 5 and the power terminals of the two remain in contact and form corresponding signal circuits and power circuits. When the lock housing 3 is in the incompletely locked position, the connector body 4 is partially inserted into the receptacle connector 2 at this time, and the signal terminals 5 of the two are disconnected and the signal circuit is disconnected. When the lock housing 3 is in the completely separated position, the connector body 4 and the receptacle connector 2 are completely disengaged at this time, and the signal terminals 5 of both are disconnected from the power terminals.

A secondary interlocking mechanism is provided between the connector body 4 and the lock housing 3. When the secondary lock of the secondary interlocking mechanism is unlocked, the locking shell 3 can slide between the complete locking position and the incomplete locking position, so that the connector body 4 and the socket connector 2 can be changed from the complete plugging state to the incomplete plugging state or from the incomplete plugging state to the complete plugging state, and when the secondary lock of the secondary interlocking mechanism is unlocked, the locking shell 3 can slide between the incomplete locking position and the complete separating position, so that the connector body 4 and the socket connector 2 can be changed from the incomplete plugging state to the complete breaking plugging state or from the complete breaking plugging state to the incomplete plugging state, and the requirement of high-pressure interlocking is met.

In the above structure, the signal terminals 5 are always located on the connector body 4, and the risk of losing or accidental damage due to the independent arrangement of the signal terminals 5 is avoided while the components are reduced. When the plugging operation is carried out, the requirement of high-voltage interlocking can be met by only moving the locking shell 3, so that the locking shell 3 is locked at a required position under the action of the secondary interlocking mechanism, and the operation is simple. The connector assembly employing the high-voltage interlock corner connector 1 described above is thus easy to perform the plugging operation.

Based on the above scheme principle, embodiment 1 of the connector assembly of the present invention is:

A connector assembly, the structure of which can be seen with reference to figure 1, comprises a high voltage interlocking corner connector 1 and a receptacle connector 2. Wherein the high-voltage interlock corner connector 1 comprises a connector body 4 and a locking housing 3. The connector body 4 is provided with power terminals for making contact with the receptacle connector 2 and forming a power circuit, and the lock housing 3 is slidably fitted to the connector body 4. The locking housing 3 may be specifically structured as shown in fig. 2 or 3, and is provided with a guide-linkage structure so as to cooperate with the linkage-cooperation structure of the receptacle connector 2. In this embodiment, the guiding linkage mechanism is specifically a guiding groove 6 provided on the locking housing 3, and the linkage mating structure is a guiding lug 7 provided on the receptacle connector 2. The guide groove 6 is specifically a chute or an arc groove, and is in guiding sliding fit with the guide lug post 7, so that the sliding of the locking shell 3 relative to the connector body 4 can drive the connector body 4 and the socket connector 2 to move in the plugging direction, and further the mutual plugging or disconnection of the connector body 4 and the socket connector 2 is realized. The guiding linkage mechanism and the linkage matching structure are consistent with the prior art, so that redundant description is omitted.

The connector body 4 has an external configuration as shown with reference to fig. 4, and is internally provided with signal terminals 5 for making contact with the receptacle connector 2 and forming a signal circuit. On the basis of this, the locking housing 3 has a full locking position, an incomplete locking position and a full release position in its sliding travel. Since the conductive position of the signal terminal 5 is later than the conductive position of the power terminal and the length of the electrical contact between the power terminal and the power terminal on the receptacle connector 2 is longer than the length of the electrical contact between the signal terminal 5 and the signal terminal 5 on the receptacle connector 2, the power terminal may make electrical contact and conduct the power circuit prior to the signal terminal 5 when the connector assembly is plugged in, and the power terminal may be out of electrical contact later than the signal terminal 5 when the connector assembly is disconnected, so that the power circuit is disconnected later than the signal circuit. When the locking housing 3 is in the fully locked position, the connector body 4 and the receptacle connector 2 are fully plugged together, and the signal terminals 5 and the power terminals of the two remain in contact and form corresponding signal circuits and power circuits. When the lock housing 3 is in the incompletely locked position, the connector body 4 is partially inserted into the receptacle connector 2 at this time, and the signal terminals 5 of the two are disconnected to disconnect the signal circuit. When the lock housing 3 is in the completely separated position, the connector body 4 and the receptacle connector 2 are completely disengaged at this time, and the signal terminals 5 of both are disconnected from the power terminals. A secondary interlocking mechanism is also arranged between the connector body 4 and the locking shell 3. When the secondary lock of the secondary interlocking mechanism is unlocked, the locking shell 3 can slide between the complete locking position and the incomplete locking position, so that the connector body 4 and the socket connector 2 can be changed from the complete plugging state to the incomplete plugging state or from the incomplete plugging state to the complete plugging state, and when the secondary lock of the secondary interlocking mechanism is unlocked, the locking shell 3 can slide between the incomplete locking position and the complete separating position, so that the connector body 4 and the socket connector 2 can be changed from the incomplete plugging state to the complete breaking plugging state or from the complete breaking plugging state to the incomplete plugging state, and the requirement of high-pressure interlocking is met. The above structure makes the signal terminal 5 always located on the connector main body 4, reduces the risk of losing or accidentally damaging the signal terminal 5 when the components are independently arranged, and simplifies the plugging operation of the connector assembly.

The key point of this embodiment is that the secondary interlocking mechanism includes, as shown in fig. 5 and 6, a lock seesaw 8 rotatably provided on the lock housing 3, and a primary lock catch 9 and a secondary lock catch 10 provided on the connector main body 4 and arranged in the sliding direction of the lock housing 3. The lower side surface of one end of the locking seesaw 8, which faces the connector plugging position, is provided with a primary lock hook 11 which can be hooked and matched with the primary lock catch 9, and the lower side surface of the other end is provided with a secondary lock hook 12 which can be hooked and matched with the secondary lock catch 10. When the high-voltage interlocking corner connector 1 is inserted with the socket connector 2, the first-stage latch hook 11 is released from hooking engagement with the first-stage latch when swinging upwards along with the locking seesaw 8, and the second-stage latch hook 12 is released from hooking engagement with the second-stage latch when swinging downwards. In this embodiment, the specific structure of the secondary interlocking mechanism may refer to the technical solution disclosed in the chinese application of the invention with publication number CN111641077a, that is, the locking seesaw 8 may specifically adopt the locking plate structure described in the application of the invention, and may be rotatably assembled on the locking housing 3 through a shaft arranged perpendicular to the sliding direction of the sliding block of the locking housing 3, so that when one end of the locking seesaw 8 rotates to be close to the locking housing 3, the other end may synchronously rotate and be far away from the locking housing 3. The primary latch hook 11 and the secondary latch hook 12 on the locking seesaw 8 can refer to the primary latch hook 11 and the secondary latch hook 12 on the locking plate in the application of the invention, and the primary latch 9 and the secondary latch 10 on the connector main body 4 can refer to the primary latch and the secondary latch on the socket connector 2 in the application of the invention, so that the plug connector and the socket connector 2 between the locking shell 3 and the connector main body 4 can have the effect of twice locking.

As shown in fig. 5, after the high-voltage interlocking corner connector 1 and the receptacle connector 2 are inserted in place, the primary latch hook 11 and the primary latch 9 are hooked with each other, so that the latch housing 3 is maintained in the fully latched position. At this time, the power terminal and the signal terminal 5 in the high-voltage interlocking corner connector 1 are respectively in electrical contact 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 conducted. When the locking device is pulled out, one end of the locking seesaw 8, which is opposite to the plugging part of the connector, is pressed first, so that the primary lock hook 11 is disengaged from the primary lock catch 9, and the locking shell 3 can move from the complete locking position to the incomplete locking position. When the locking shell 3 moves from the complete locking position to the incomplete locking position, the high-voltage interlocking corner connector 1 and the socket connector 2 also change from the complete plugging state to the incomplete plugging state through the linkage fit of the guide groove 6 on the locking shell 3 and the guide lug post 7 on the socket connector 2, and the signal terminal 5 is firstly separated from electrical contact to disconnect a signal circuit. The secondary lock hook 12 and the secondary lock catch 10 are hooked and matched with each other at this time, so that the locking shell 3 is kept at an incomplete locking position. When the connector is pulled out continuously, the locking seesaw 8 is pressed towards one end of the connector plugging position, so that the secondary lock hook 12 is disengaged from the secondary lock catch 10, and the locking shell 3 can move from the incomplete locking position to the complete separation position. When the locking shell 3 moves from the incomplete locking position to the complete disengaging position, the high-voltage interlocking corner connector 1 and the socket connector 2 are also changed from the incomplete plugging state to the complete disengaging state through the linkage fit of the guide groove 6 on the locking shell 3 and the guide lug post 7 on the socket connector 2, and the power terminal is separated from electrical contact to disconnect the power circuit. The structure simplifies the technical scheme of secondary locking, so that when the connector assembly is inserted and separated, the locking shell 3 can be controlled to move in a segmented mode only by controlling the locking seesaw 8, the technical purpose that a signal loop and a power loop on the connector assembly are opened and closed step by step according to high-voltage interlocking requirements is achieved, and the operation when the connector assembly is inserted and separated is greatly simplified.

It is easily conceivable that the aforementioned secondary interlocking mechanism may also be a first latch and a second latch provided on the connector body 4 and arranged in the sliding direction of the lock housing 3, and a latch window provided on the lock housing 3 for snap-fitting with the first latch and the second latch. When the high-voltage interlocking corner connector 1 and the socket connector 2 are inserted in place, the first elastic claw and the buckling window are mutually in snap fit, so that the locking shell 3 is kept in the complete locking position. At this time, the power terminal and the signal terminal 5 in the high-voltage interlocking corner connector 1 are respectively in electrical contact 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 conducted. When the locking shell 3 is pulled out, the first elastic claw is pressed from the inside of the buckling window to make the first elastic claw forcedly retract so as to separate from the buckling window, and at the moment, the locking shell 3 can move from the complete locking position to the incomplete locking position. When the locking shell 3 moves from the complete locking position to the incomplete locking position, the high-voltage interlocking corner connector 1 and the socket connector 2 also change from the complete plugging state to the incomplete plugging state through the linkage fit of the guide groove 6 on the locking shell 3 and the guide lug post 7 on the socket connector 2, and the signal terminal 5 is firstly separated from electrical contact to disconnect a signal circuit. The second catch then engages with the catch window in a snap fit to hold the locking housing 3 in the incompletely locked position. When the locking shell 3 is pulled out continuously, the second elastic claw is pressed from the buckling window continuously to make the second elastic claw forcedly retract so as to enable the second elastic claw to be separated from the buckling window, and the locking shell 3 can move from the incomplete locking position to the complete separation position. When the locking shell 3 moves from the incomplete locking position to the complete disengaging position, the high-voltage interlocking corner connector 1 and the socket connector 2 are also changed from the incomplete plugging state to the complete disengaging state through the linkage fit of the guide groove 6 on the locking shell 3 and the guide lug post 7 on the socket connector 2, and the power terminal is separated from electrical contact to disconnect the power circuit.

Based on the above scheme principle and embodiment 1, embodiment 2 of the connector assembly of the present invention is:

The key point of this embodiment is that the secondary interlocking mechanism further includes a locking block 13 slidably mounted on the locking housing 3, compared to embodiment 1. As shown in fig. 7 and 8, the lock block 13 has a stop position for stopping an end of the lock rocker 8 facing away from the connector insertion portion in a downward direction and a relief position for letting off a space below the end in a movement stroke thereof. The locking block 13 is inserted into the lower part of one end of the locking seesaw 8, which is opposite to the connector plugging part, when the connector assembly is completely plugged in, so as to prevent the downward movement of the end, further the primary lock hook 11 and the primary lock catch 9 are kept in a locked state at all times, the primary lock hook 11 and the primary lock catch 9 are prevented from being separated from being matched due to misoperation of the locking seesaw 8, and the plugging reliability of the connector assembly is effectively ensured.

In addition to the above-described structure, as shown in fig. 7 and 8, the lock block 13 may be provided with a barb 14 on a side facing the lock housing 3. One side of the barb 14 facing the insertion direction of the locking piece 13 has a straight surface, and the other side has an arc surface connected with the straight surface. The side of the locking shell 3 facing the locking block 13 is provided with a corresponding boss 15, and the side of the boss 15 facing away from the insertion direction of the locking block 13 is provided with a straight surface so as to be in stop fit with the barb 14 when the locking block 13 slides from the avoidance position to the stop position, so that the movement of the locking block 13 is prevented. The other side of the boss 15 is provided with an inclined plane so that the barb 14 can slide over the boss 15 through the guiding of the inclined plane and the cambered surface when the locking block 13 moves from the blocking position to the avoiding displacement. Of course, the inclined plane and the cambered surface can be interchanged, or both the inclined plane and the cambered surface are the same, and the description is omitted here.

In addition, the lock block 13 may be provided with a sliding portion, and the lock housing 3 and/or the connector body 4 may be provided with a jack-up portion. In this embodiment, the sliding portion comprises in particular an arcuate head 16 at the end of the locking block 13 facing in the direction of insertion thereof, and an arcuate tail 17 at the end of the locking block 13 facing away from the direction of insertion thereof. Both sides of the arc-shaped head 16 facing and facing away from the insertion direction of the locking block 13 are provided with cambered surfaces, and one side of the arc-shaped tail 17 facing the insertion direction of the locking block 13 is provided with a cambered surface, and the other side is a straight surface. The jack-up portion includes a first jack-up portion 18 provided on the lock housing 3 and a second jack-up portion 19 provided on the connector body 4. The first jack-up portion 18 is provided on the lock housing 3, and specifically includes a straight surface facing the insertion direction of the lock block 13 and an arc surface disposed on the other side. When the locking block 13 is inserted, the arc-shaped head 16 and the barb 14 can smoothly slide over the jacking portion under the guidance of the cambered surface of the first jacking portion 18 until the straight surface of the barb 14 is in stop fit with the straight surface of the boss 15, so as to prevent the locking block 13 from sliding from the avoidance position to the stop position. The straight surface of the first jack-up part 18 is in stop fit with the straight surface of the sliding tail so as to prevent the locking block 13 from falling out. The second jack-up portion 19 all is provided with the inclined plane towards and the one side of locking piece 13 direction of inserting that is away from, and when locking piece 13 received the exogenic action to slide to the fender position from dodging the position, the inclined plane of second jack-up portion 19 cooperates with the cambered surface of arc head 16 to jack-up locking piece 13 and make barb 14 and boss 15 break away from the fender cooperation. The lock block 13 may be provided with a stop surface 20 in place to stop engagement with the straight surface of the boss 15 after the lock block 13 is slid to the stop position to prevent further sliding of the lock block 13. When the locking block 13 slides from the blocking position to the avoiding position, the cambered surface of one side of the cambered head 16, which is opposite to the insertion direction of the locking block 13, is matched with the second jacking part 19 so as to jack the locking block 13 and enable the in-place blocking surface 20 to be separated from the blocking fit with the boss 15, and at the moment, the locking block 13 can continue to slide to the avoiding position. The arrangement can make the locking block 13 have a definite position relation relative to the locking shell 3, so that the locking block 13 can be stably kept in the blocking position or the avoiding position to ensure the blocking or avoiding effect.

Of course, the first jack-up portion 18 and the second jack-up portion 19 may be provided on the lock housing 3, or only the second jack-up portion 19 may be provided on the connector body 4. On this basis, it is easily conceivable that the locking block 13 can also comprise only its blocks when the costs are limited. The locking piece 13 is held in the blocking position or in the yielding position by friction. Based on this, the lock block 13 is preferably made of a material having a large friction factor such as rubber.

The parts not mentioned in this example remain identical to example 1.
