[0049] like Figures 1 to 11 As shown, a preferred embodiment of a connector with a secondary lock described in the utility model.

[0050] The utility model provides a connector with a secondary lock. During use, the connector may become loose or disconnected due to accidental contact. To address this problem, some manufacturers have improved the connector by adding a locking structure 30. However, the locking structure 30 may also be accidentally contacted during use, causing the connector to become loose. To solve this problem, the utility model is implemented according to the following technical solutions:

[0051] A connector with a secondary lock, the connector comprising: a plug 10, a socket 20, a locking structure 30 and a secondary lock structure 40; the plug 10 comprises a plug housing 11; the socket 20 comprises a socket housing 21; the locking structure 30 comprises a locking member 31 and a limiting member 32, the locking member 31 is connected to the plug housing 11, and the limiting member 32 is connected to the socket housing 21; the secondary lock structure 40 comprises a locking member 41 and a sliding groove 42, the sliding groove 42 is arranged on the plug housing 11, the locking member 41 has a stopper 411 and a sliding boss 412, and the sliding boss 412 can slide in the sliding groove 42;

[0052] Among them, the energy storage connector has a first locked state, a first unlocked state, a second locked state and a second unlocked state; in the first locked state, the locking member 31 and the limiting member 32 conflict with each other so that the plug 10 and the socket 20 are locked; in the first unlocked state, the locking member 31 and the limiting member 32 are released from conflict; in the second locked state, the stopper 411 stops the locking member 31, so that the locking member 31 and the limiting member 32 cannot be released from conflict; in the second unlocked state, the stopper 411 releases the stop of the locking member 31.

[0053] It can be understood that after the energy storage connector plug 10 and the socket 20 are plugged in, the locking member 31 on the plug shell 11 of the locking structure 30 and the limiting member 32 on the socket shell 21 interfere with each other, so that the plug 10 and the socket 20 cannot be separated, thereby achieving the first locking. In order to make the locking more stable, a secondary locking structure 40 is added for secondary locking.

[0054] The locking member 31 has a first end 311 and a second end 312 , and a middle portion of the locking member 31 is connected to the plug housing 11 ; a latching tooth 313 is formed inside the first end 311 of the locking member 31 .

[0055] It can be understood that the middle portion of the locking member 31 is connected to the plug housing 11 , and the first end 311 and the second end 312 of the locking member 31 are independent of the plug housing 11 .

[0056] The limiting member 32 is a snap ring or a slot. The limiting member 32 can be set as a slot, so that the latching teeth 313 on the locking member 31 can conflict with the inside of the slot to achieve the first locking. Figure 7 The limiting member 32 can be set as a snap ring, and the locking teeth 313 on the locking member 31 can conflict with the side wall of the snap ring to achieve the first locking, that is, the first locking state.

[0057] Locking members 31 are provided on both sides of the socket housing 21. When the second ends 312 of the locking members 31 on both sides of the socket housing 21 are pressed simultaneously, the first ends 311 of the locking members 31 will be tilted, and the interference between the card slots or the snap rings will be released, that is, the locking members 31 and the limiting members 32 are no longer in conflict, and the socket 20 and the plug 10 can be separated, which is the first unlocking state.

[0058] Stoppers 411 are disposed on both sides of the locking member 41 , and positions of the stoppers 411 correspond to the second ends 312 of the locking member 31 .

[0059] Combination Fig. 9 The stopper 411 is arranged at the inner side of the second locking end 312, and is used to stop the second end 312 of the locking member 31, so as to prevent the second end 312 from being accidentally pressed during use, resulting in the separation between the locking member 31 and the limiting member 32, and the separation between the socket 20 and the plug 10. The stopping of the second end 312 of the locking member 31 is the second locking state.

[0060] The locking member 41 has a sliding boss 412, which is preferably hemispherical in shape in this embodiment; the interior of the sliding groove 42 has an arc, which matches the sliding boss 412. The sliding boss 412 can slide in the sliding groove 42, and a backstop 421 is also provided in the middle of the sliding groove 42, which can be a protrusion; the backstop 421 divides the sliding groove 42 into an upper groove 422 and a lower groove 423. When the sliding boss 412 is in the lower groove 423, the stop member 411 is still on the inner side of the second end 312 of the locking member 31, and can stop the second end 312 of the locking member 31, and cannot press the second end 312 of the locking member 31; when the sliding boss 412 is slid to the upper groove 422, the position of the stop member 411 also rises accordingly, and at this time the second end 312 of the locking member 31 cannot be stopped, and it is in the second unlocking state, and the second end 312 of the locking member 31 can be pressed to unlock.

[0061] The socket housing 21 is provided with a first boss 111, and there is a gap between the first boss 111 and the socket housing 21; the locking member 41 is provided with a second boss 413, and the second boss 413 is placed in the gap; the first boss 111 is used to stop the first boss 111. The first boss 111 and the second boss 413 cooperate with each other to prevent the locking member 41 from being separated from the plug housing 11.

[0062] In a specific implementation, the plug housing 11 has a display block 112, and the display block 112 has a locking mark, such as Fig.10 As shown, the lock marks are "Lock" and "Unlock", which are used to indicate whether it is unlocked or locked; the secondary lock structure 40 has a hollow portion 43, and the hollow portion 43 reveals the display block 112, and the display block 112 is just placed in the hollow portion 43. The length of the hollow portion 43 is longer than the display block 112. When in the second locked state, the top of the display block 112 just contacts with the upper part of the hollow portion 43, and when in the second unlocked state, the bottom of the display block 112 just contacts with the lower part of the hollow portion 43.

[0063] The plug 10 further includes a connection terminal 12 connected to the plug housing 11 ; the connection terminal 12 is used to connect to a cable; the socket 20 further includes a pin 22 connected to the socket housing 21 .

[0064] A connector with a secondary lock, the connector comprising: a plug 10, a socket 20, a locking structure 30 and a secondary lock structure 40; the plug 10 comprises a plug housing 11; the socket 20 comprises a socket housing 21; the locking structure 30 comprises a locking member 31 and a limiting member 32, the locking member 31 is connected to the plug housing 11, and the limiting member 32 is connected to the socket housing 21; the secondary lock structure 40 comprises a locking member 41 and a sliding groove 42, the sliding groove 42 is arranged on the plug housing 11, the locking member 41 has a stopper 411 and a sliding boss 412, the sliding boss 412 The platform 412 can slide in the sliding groove 42; wherein, the energy storage connector has a first locking state, a first unlocking state, a second locking state and a second unlocking state; in the first locking state, the locking member 31 and the limiting member 32 conflict with each other so that the plug 10 and the socket 20 are locked; in the first unlocking state, the locking member 31 and the limiting member 32 are released from conflict; in the second locking state, the stopper 411 stops the locking member 31, so that the locking member 31 and the limiting member 32 cannot be released from conflict; in the second unlocking state, the stopper 411 releases the stop of the locking member 31.

[0065] The utility model has a double locking structure 30, which can effectively prevent the plug 10 and the socket 20 from being separated during the use of the connector, thereby improving the safety and practicality of the connector.
