As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items, unless specifically stated or otherwise defined.

For convenience of description, unless otherwise specified, the right-left direction hereinafter is identical to the right-left direction of fig. 1 itself, and the up-down direction hereinafter is identical to the up-down direction of fig. 1 itself.

The connector, also called high voltage connector, comprises means for electrically connecting two cables by plugging the male and female terminals into each other, i.e. by plugging between a plug and a socket.

As shown in fig. 1 to 8, the present embodiment provides a connector including a first base 1, a second base 2 for sliding on the first base 1, and a first unlocking seat 3, a second unlocking seat 4 mounted on the second base 2. The first base 1 corresponds to a socket, the second base 2 corresponds to a plug, and it is understood that the first base 1 may be a plug, and the second base 2 may be a socket.

When the second base 2 is connected to the first base 1, the second base 2 slides on the first base 1 to a predetermined position, and the connection is completed. When the second base 2 is separated from the first base 1, the second base 2 slides away from the first base 1. The first unlocking seat 3 and the second unlocking seat 4 are respectively movably arranged on the second base 2. The second base 2 can drive the first unlocking seat 3 and the second unlocking seat to slide when sliding.

The first unlocking seat 3 and the second unlocking seat 4 are each swingable with respect to the first base 1 to switch between a locked state in which the first base 1 and the second base 2 are locked and an unlocked state in which the locking of the first base 1 and the second base 2 is released. The first unlocking seat 3 and the second unlocking seat 4 are both in a locking state and an unlocking state, when the first unlocking seat 3 is in the locking state, the first base 1 and the second base 2 can be locked, the second base 2 can not slide relative to the first base 1, when the first unlocking seat 3 is in the unlocking state, the first base 1 and the second base 2 can be unlocked, and the second base 2 can slide relative to the first base 1; when the second unlocking seat 4 is in the locking state, the first base 1 and the second base 2 can be locked, the second base 2 can not slide relative to the first base 1, and when the second unlocking seat 4 is in the unlocking state, the first base 1 and the second base 2 can be unlocked, and the second base 2 can slide relative to the first base 1. When the first unlocking seat 3 and the second unlocking seat 4 lock the first base 1, the connection between the first unlocking seat 3 and the second unlocking seat 4 and the first base 1 includes, but is not limited to, detachable connection such as buckling, clamping connection and the like.

When the connector is unlocked, the first base 1 and the second base 2 are separated from each other, the second base 2 moves in a direction of separating from the first base 1, and the locking state of the first unlocking seat 3 and the locking state of the second unlocking seat 4 are sequentially performed. That is, when the first base 1 and the second base 2 are separated from each other, it is necessary to switch the first unlocking seat 3 from the locked state to the unlocked state and then switch the second unlocking seat 4 from the locked state to the unlocked state. Specifically, when the connector is in operation, the first unlocking seat 3 is kept in a locked state, so that the first base 1 is electrically connected with the second base 2, and when the connector is unlocked, the first unlocking seat 3 needs to be switched to an unlocked state. After the first unlocking seat 3 is switched to the unlocking state and then drives the second base 2 to slide for a certain distance along the direction separated from the first base 1, the electrical connection between the first base 1 and the second base 2 is disconnected, but the second unlocking seat 4 enters the locking state, and the first base 1 and the second base 2 are also kept in physical connection. Finally, the second unlocking seat 4 is required to be switched to an unlocking state, so that the physical connection between the first base 1 and the second base 2 can be disconnected, and the first base 1 and the second base 2 are separated.

In order to avoid that the second unlocking seat 4 is also switched to the unlocking state when the first unlocking seat 3 is switched to the unlocking state, and to prevent the electrical connection and the physical connection between the first base 1 and the second base 2 from being simultaneously disconnected, that is, to avoid that the second base 2 is pulled out in a live mode, the first unlocking seat 3 of the connector of the present application can lock the second unlocking seat 4 to limit the unlocking state of the second unlocking seat 4 when the first unlocking seat 3 is switched to the unlocking state, thereby preventing the second unlocking seat 4 from being switched to the unlocking state. The first unlocking seat 3 locks the second unlocking seat 4 in various manners, for example, the first unlocking seat 3 moves to a swinging path where the second unlocking seat 4 is switched to an unlocking state, so that the second unlocking seat 4 is prevented from unlocking the locking state, when the first unlocking seat 3 finishes switching to the unlocking state to disconnect the connection between the first unlocking seat 3 and the first base 1, the first unlocking seat 3 is separated from the unlocking state and the unlocking state of the second unlocking seat 4 is not limited any more, and the second unlocking seat 4 can be switched to the unlocking state, so that the physical separation between the first base 1 and the second base 2 is realized. It will be appreciated that the first unlocking seat 3 may be moved to the unlocking state to push other intermediate members to move to the swing path when the second unlocking seat 4 is switched to the unlocking state, so that the swing of the second unlocking seat 4 may be restricted.

Therefore, the connector can realize that the electrical connection between the first base 1 and the second base 2 is disconnected firstly, so that the connector is prevented from being pulled out in a live mode, and then the physical connection between the first base 1 and the second base 2 is disconnected, so that the contact or the connector is prevented from being ablated, the occurrence of safety accidents is prevented, and the operation safety of the connector is improved.

In one embodiment, the connector further comprises an unlocking prevention seat 5 slidably provided on the second base 2. The unlocking prevention seat 5 is a CPA locking mechanism. The second base 2 is detachably connected with the first base 1 through the first unlocking seat 3 and the second unlocking seat 4, primary locking is achieved when the second base 2 is connected with the first base 1 through the second unlocking seat 4, secondary locking is achieved when the second base 2 is connected with the first base 1 through the first unlocking seat 3, and the second base 2 is connected with the first base 1. When the first unlocking seat 3 is separated from the first base 1, the first unlocking is realized, when the second unlocking seat 4 is separated from the second base 2, the second unlocking is realized, and the second base 2 can be separated from the first base 1. When the second base 2 is connected with the first base 1, the second base 2 is slidably arranged on the first base 1, and the second base 2 is locked respectively through the first unlocking seat 3 and the second unlocking seat 4 when sliding to different positions.

It is conceivable that the first unlocking seat 3 and the second unlocking seat 4 may also be mounted on the first base 1, both the first unlocking seat 3 and the second unlocking seat 4 being detachably connected with the second base 2.

Specifically, the second base 2 has a full lock state, a half lock state, and a free state; in the fully locked state, the first unlocking seat 3 and the second unlocking seat 4 are connected with the first base 1, and the second base 2 is connected with the first base 1 and cannot slide. In the half-locking state, the first unlocking seat 3 is separated from the first base 1, the second unlocking seat 4 is connected with the first base 1, the second base 2 can be still connected with the first base 1, in the free state, the first unlocking seat 3 and the second unlocking seat 4 are both separated from the first base 1, the second base 2 can freely slide on the first base 1, and the second base 2 can also slide off from the first base 1.

The first unlocking seat 3 and the second unlocking seat 4 are switched between a locking state and an unlocking state; the first unlocking seat 3 is in a locking state, the first unlocking seat 3 is connected with the first base 1, the first unlocking seat 3 is in an unlocking state, and the first unlocking seat 3 is separated from the first base 1; similarly, the second unlocking seat 4 is in a locking state, the second unlocking seat 4 is connected with the first base 1, the second unlocking seat 4 is in an unlocking state, and the second unlocking seat 4 is separated from the first base 1.

The unlocking prevention seat 5 is switched between a first position and a second position; when the unlocking prevention seat 5 is at the first position, the unlocking prevention seat 5 can prevent the first unlocking seat 3 from switching positions. When the unlocking prevention seat 5 is in the second position, the first unlocking seat 3 can be switched between the locked state and the unlocked state.

When the second base 2 is in the full-locking state, the unlocking prevention seat 5 slides to the first position, the unlocking prevention seat 5 locks the first unlocking seat 3 to limit the first unlocking seat 3 to be out of the locking state, the unlocking prevention seat 5 enables the first unlocking seat 3 to be kept connected with the first base 1, and at the moment, the second unlocking seat 4 is also kept connected with the first base 1.

When the second base 2 is in the half-locking state, the unlocking prevention seat 5 slides to the second position, the first unlocking seat 3 moves to the unlocking state and locks the second unlocking seat 4 to limit the second unlocking seat 4 to be out of the locking state; the first unlocking seat 3 can move to the moving path of the second unlocking seat 4 when moving to the unlocking state so as to prevent the second unlocking seat 4 from moving; when the first unlocking seat 3 moves to the unlocking state, a part of the unlocking preventing seat 5 or other parts can be driven to move to the moving path of the second unlocking seat 4, so that the second unlocking seat 4 can be prevented from moving, and the second unlocking seat 4 can not be switched between the unlocking state and the locking state. When the first unlocking seat 3 is in an unlocking state, the second base 2 is slid, so that the first unlocking seat 3 is separated, the second unlocking seat 4 is locked in the process, and the second unlocking seat 4 is kept connected with the second base 2. After the first unlocking seat 3 is separated from the first base 1, the first unlocking seat 3 can be separated from the unlocking state, at this time, the locking of the second unlocking seat 4 is released, and the second unlocking seat 4 can be switched between the unlocking state and the locking state.

When the second base 2 is in the free state, the unlocking prevention seat 5 is located at the second position, and the unlocking prevention seat 5 releases the restriction on the first unlocking seat 3. The first unlocking seat 3 and the second unlocking seat 4 respectively move to an unlocking state; that is, the first unlocking seat 3 is firstly switched to the unlocking state, after the first unlocking seat 3 is separated from the first base 1, the first unlocking seat 3 is separated from the unlocking state, the locking of the second unlocking seat 4 is released, the second unlocking seat 4 can be switched from the locking state to the unlocking state, and finally, the second unlocking seat 4 is separated from the first base 1, and the second base 2 is switched to the free state.

The second base 2 is kept connected with the first base 1 when the second base 2 is in the full-lock state or the half-lock state, and the second base 2 can be separated from the first base 1 when the second base 2 is in the free state.

In one embodiment, the fully locked state, the half locked state, and the free state of the second base 2 are sequentially switched when the second base 2 slides in a direction away from the first base 1. The second base 2 is in a free state when the second base 2 is separated or when the second base 2 is just slidably provided on one end of the first base 1. Then slide the second base 2 for the second base 2 continues to be close to first base 1, then is connected with first base 1 with second unblock seat 4, accomplishes once locking, and second base 2 switches to half locking state, and is connected with first base 1 with first unblock seat 3 at last, accomplishes the secondary locking, and second base 2 switches to full locking state, and the electric connection of first base 1 and second base 2 is put through this moment. When the second base 2 is in the full locking state, the first unlocking seat 3 is separated from the first base 1, the second base 2 is switched to the half locking state, then the second unlocking seat 4 is separated from the first base 1, the second base 2 is switched to the free state, and finally the second base 2 is separated from the first base 1 by sliding the second base 2.

In one embodiment, the first unlocking seat 3 and the second unlocking seat 4 are detachably connected with the first base 1. Alternatively, the first base 1 has a first engaging portion 101, the first unlocking seat 3 has a second engaging portion 301, and the second unlocking seat 4 has a third engaging portion 401. The second engaging portion 301 and the third engaging portion 401 may be engaged with the first engaging portion 101, and the first unlocking seat 3 and the first base 1, and the second unlocking seat 4 and the first base 1 may be detachably connected. Specifically, when the first unlocking seat 3 is in the locked state, the second engaging portion 301 engages with the first engaging portion 101, and when the second unlocking seat 4 is in the locked state, the third engaging portion 401 engages with the first engaging portion 101; when the first unlocking seat 3 is in the unlocked state, the second engaging portion 301 is separated from the first engaging portion 101, and when the second unlocking seat 4 is in the unlocked state, the third engaging portion 401 is separated from the first engaging portion 101.

It should be understood that in other embodiments, the first base 1 may be provided with a fourth engaging portion, where the first engaging portion 101 and the second engaging portion 301 are engaged with each other to realize the detachable connection between the first unlocking seat 3 and the first base 1, and the fourth engaging portion and the third engaging portion 401 are engaged with each other to realize the detachable connection between the second unlocking seat 4 and the first base 1.

In order to realize the function of disconnecting the electrical connection and then disconnecting the physical connection of the connector, the second clamping portion 301 and the third clamping portion 401 are sequentially arranged along the sliding path of the second base 2, so as to realize one-time unlocking of the first unlocking seat 3 and the second unlocking seat 4. Alternatively, the third engaging portion 401 and the second engaging portion 301 are sequentially arranged along the sliding direction in which the second base 2 is separated from the first base 1, and when the second base 2 is separated from the first base 1, the second engaging portion 301 is separated from the first engaging portion 101, and then the second base 2 is slid by a distance to separate the third engaging portion 401 from the first engaging portion 101; when the second base 2 is connected to the first base 1, the third engaging portion 401 and the first engaging portion 101 are engaged with each other, and then the second base 2 is slid by a distance, and the second engaging portion 301 and the first engaging portion 101 are engaged with each other; the second engagement portion 301 and the third engagement portion 401 are sequentially along the sliding path of the second base 2, so that the secondary locking and the secondary unlocking are sequentially performed.

In one embodiment, when the unlocking prevention seat 5 is in the first position, the unlocking prevention seat 5 may also prevent the second unlocking seat 4 from switching positions. The unlocking prevention seat 5 can also lock the second lock seat to limit the second unlocking seat 4 to be separated from the locking state, so that the second unlocking seat 4 is kept connected with the first base 1, and the second base 2 is kept stably connected with the first base 1 when the second base 2 is in the full locking state.

In one embodiment, the second base 2 has a supporting portion 201, the supporting portion 201 is used for supporting the first unlocking seat 3 and the second unlocking seat 4, the first unlocking seat 3 and the second unlocking seat 4 are movably installed on the supporting portion 201, and by driving the first unlocking seat 3 and the second unlocking seat 4 to move, the first unlocking seat 3 and the second unlocking seat 4 can be switched between an unlocking state and a locking state.
