Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an energy storage connector and a connection structure thereof. Background Art

[0002] Energy storage connectors are usually used as connecting components between energy storage devices and electrical equipment to realize high current transmission between the energy storage devices and electrical equipment. Existing energy storage connectors mainly include plug connectors and socket connectors that are mated together. After mating, the plug connector and the socket connector must be reliably locked to prevent the plug connector from accidentally detaching from the socket connector.

[0003] At present, the anti-mock design of the plug connector and the socket connector when mating mostly requires that they be mated at a fixed angle, and the plug connector is usually connected to the socket with an anti-mock cap to achieve locking of the plug connector and the socket connector. Since the anti-mock cap is also fixed to the socket shell by means of snaps, etc., the plug connector is not directly connected to the socket shell. After locking, the plug connector shakes a lot, and the locking strength also has hidden dangers. Moreover, after mating, the plug connector cannot be rotated relative to the socket connector, and the arrangement angle of the plug connector has great limitations. Utility Model Content

[0004] The purpose of the present utility model is to provide an energy storage connector and its connection structure, which are used to solve the technical problems in the prior art that the plug connector cannot be rotated relative to the socket connector after being plugged in, and the locking strength is insufficient when the plug connector is fixed with an anti-mock cap on the socket to achieve locking of the plug connector and the socket connector by means of a snap or the like.

[0005] The utility model solves the above problems through the following technical solutions:

[0006] An energy storage connector connection structure includes: a plug housing, a socket housing and an anti-foolproof cap. The socket housing is axially fixedly connected to the plug housing, and the anti-foolproof cap is circumferentially fixedly connected to the plug housing. The plug housing and the anti-foolproof cap are engaged with each other. The engagement position of the anti-foolproof cap and the socket housing is adjusted by rotating the plug housing, so that the plug housing can rotate relative to the socket housing.

[0007] As a further improvement, the fool-proof cap is arranged between the plug housing and the socket housing, and is formed with a plurality of anti-rotation key grooves therein; and a plurality of anti-rotation bosses engaged with the anti-rotation key grooves are formed outside the socket housing.

[0008] As a further improvement, the anti-rotation bosses are provided in no less than four pieces, the number of which is greater than the fourth boss of the fool-proof cap, and are spaced apart on the outer peripheral surface of the socket housing.

[0009] As a further improvement, the number of the anti-rotation key slots is no less than eight, and the number is an integer multiple of the anti-rotation bosses of the socket housing.

[0010] As a further improvement, the plug housing is connected to the socket housing by a hook, and the fool-proof cap is pressed between the plug housing and the socket housing, and the axial limit realizes the rotation function.

[0011] As a further improvement, the plug housing is provided with a plurality of fool-proof key slots, and the outside of the fool-proof cap is formed with a plurality of fool-proof convex keys that match the fool-proof key slots to achieve key connection.

[0012] As a further improvement, a third boss is formed on the outside of the socket housing and is connected to a hook and buckle in the plug housing;

[0013] An annular groove is formed between the third boss and the anti-rotation boss of the socket housing, and a plurality of fourth bosses matching the annular groove are arranged in the fool-proof cap.

[0014] As a further improvement, a first cavity and a second cavity connected to each other are formed in the plug housing, and a locking block is provided in the first cavity. The locking block can reciprocate between a locking position and an unlocking position in the first cavity to limit the hook away from the side of the socket housing.

[0015] As a further improvement, the locking block has a first boss and a second boss arranged in parallel. Before the plug housing and the socket housing are mated, the second boss abuts against the hook in the first cavity; after the plug housing and the socket housing are mated, the first boss is located in the second cavity, and the second boss abuts against the bottom of the hook in the first cavity.

[0016] At the same time, the present invention also solves the above problems through the following technical solutions:

[0017] An energy storage connector includes: a plug connector, a socket connector and an anti-foolproof cap, wherein the plug housing of the plug connector is axially fixedly connected to the socket housing of the socket connector, the anti-foolproof cap is circumferentially fixedly connected to the plug housing, the plug housing and the anti-foolproof cap are engaged, and the engagement position of the socket housing and the anti-foolproof cap is adjusted by rotating the socket housing, so that the plug housing can rotate relative to the socket housing.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] (1) The fool-proof cap of the present invention can be rotated circumferentially after being installed in the socket housing. The engagement of the anti-rotation keyway and the anti-rotation boss can provide a certain rotational resistance to lock the fool-proof cap, thereby allowing the plug connector to be maintained at a desired angle, thereby improving the stability of the electrical contact.

[0020] (2) The hook of the plug connector of the utility model is integrally formed with the socket housing, which effectively improves the locking strength of the plug connector and the socket connector. A locking block is also designed in the plug connector to perform secondary locking of the hook, which can prevent the hook from being separated from the socket connector due to accidental contact or misoperation, thereby reducing the risk of the plug connector accidentally falling off from the socket connector.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] Combined with attachment Figure 1-6As shown, an energy storage connector connection structure includes: a plug housing 3, a socket housing 4 and an anti-foolproof cap 6. The socket housing 4 is axially fixedly connected to the plug housing 3, and the anti-foolproof cap 6 is circumferentially fixedly connected to the plug housing 3. The plug housing 3 is engaged with the anti-foolproof cap 6. By rotating the socket housing 4, the engagement position of the socket housing 4 and the anti-foolproof cap 6 is adjusted, so that the plug housing 3 can be rotated relative to the socket housing 4, ensuring that the arrangement angle of the plug housing 3 is adjustable at multiple angles and avoiding shaking of the socket housing 4.

[0032] A further technical solution is that the anti-fouling cap 6 is arranged between the plug housing 3 and the socket housing 4, and a plurality of anti-rotation key grooves 602 are formed therein; the plug housing 3 and the socket housing 4 are hooked and connected to achieve axial fixation, and a plurality of anti-rotation bosses 402 are formed on the outside of the socket housing 4, and the anti-rotation bosses 402 are engaged with the anti-rotation key grooves 602 to adjust the engaging position by the amount of extrusion deformation.

[0033] Specifically, in this embodiment, the plug connector 1 includes a plug housing 3 and a locking block 5, a first cavity 301 and a second cavity 304 that are connected to each other are formed in the plug housing 3, the locking block 5 has a first boss 501 and a second boss 502 that are arranged in parallel and connected at one end, the locking block 5 is arranged in the first cavity 301 at the front end of the plug housing 3, and the locking block 5 can reciprocate between a locked position and an unlocked position in the first cavity 301 to limit the hook 302 away from the side of the socket housing 4.

[0034] The socket connector 2 includes a socket housing 4 and a fool-proof cap 6 . The fool-proof cap 6 is mounted on the outer peripheral surface of the socket housing 4 and can be rotated 360° on the socket housing 4 .

[0035] A further technical solution is that a first cavity 301 is provided at the front end of the plug housing 3 for placing the locking block 5. Before the plug connector 1 is mated with the socket connector 2, the second boss 502 on the locking block 5 abuts against the hook 302 formed in the first cavity 301, so that the locking block 5 can be maintained in the unlocked position. At this time, the second cavity 304 is a cavity, and the hook 302 has deformation space in the second cavity 304.

[0036] A circle of third bosses 401 is provided on the outer peripheral surface of the socket housing 4. After the plug connector 1 and the socket connector 2 are mated, the third boss 401 and the hook 302 form a detachable hook connection, and the second boss 502 on the locking block 5 is pressed against the hook 302 formed in the first cavity 301. At this time, the first boss 501 on the locking block 5 is located in the second cavity 304, and the hook 302 has no deformation space, providing secondary locking for the hook 302, which can prevent the hook 302 from detaching from the third boss 401 due to accidental contact or misoperation, thereby reducing the risk of the plug connector 1 accidentally detaching from the socket connector 2.

[0037] The outer circumferential surface of the socket housing 4 is provided with anti-rotation bosses 402 distributed at intervals, and correspondingly, the inner circumferential surface of the fool-proof cap 6 is provided with anti-rotation key grooves 602. In this embodiment, the number of anti-rotation bosses 402 is set to be no less than eight, so that the fool-proof cap 6 can be rotated at any angle, and at least four anti-rotation bosses 402 are located in the anti-rotation key grooves 602, that is, the number of anti-rotation bosses 402 is set to be no less than four. In this embodiment, since a plurality of anti-rotation key grooves 602 are spaced apart inside the fool-proof cap 6, in order to prevent the anti-rotation boss 402 from being located in the spaced position, and a fourth boss 603 is provided below the spaced position, thereby preventing the anti-rotation boss 402 from engaging with the anti-rotation key groove 602, the number of anti-rotation bosses 402 is set to be greater than the number of fourth bosses 603 provided on the fool-proof cap. When the plug connector 1 and the socket connector 2 are matched, the rotating plug connector 1 can drive the anti-fool cap 6 to rotate relative to the socket housing 4. During the rotation of the socket housing 4, the anti-fool cap 6 can engage with the anti-rotation boss 402 and the anti-rotation key slot 602 to provide a certain rotation resistance, so that the plug connector 1 can maintain the desired angle after the angle adjustment is completed, thereby increasing the stability of the connection between the plug connector 1 and the socket connector 2.

[0038] In this embodiment, the foolproof cap 6 is disposed between the plug connector 1 and the receptacle connector 2, and is pressed into position therebetween by a hook connection between the plug connector 1 and the receptacle connector 2. Only the circumferential position of the foolproof cap 6 and the plug connector 1 is required. Optionally, the inner circumferential surface of the plug housing 3 is further provided with a foolproof keyway 303. The number of foolproof keyways 303 is typically greater than or equal to two, and matching foolproof protrusions 601 arranged at the same angle are required to mate with the foolproof cap 6 to achieve a key connection. Of course, the foolproof cap 6 and the plug connector 1 can also be connected using other fixing methods to ensure both circumferential and axial fixation, such as a hook connection or other connection methods.

[0039] Optionally, to ensure the connection strength between the foolproof cap 6 and the socket housing 4 and further prevent the socket connector 2 from shaking, an annular groove 403 is formed between the third boss 401 and the anti-rotation boss 402 of the socket housing 4. Correspondingly, a plurality of fourth bosses 603 are spaced apart within the foolproof cap 6 below the anti-rotation key slot 602. The annular grooves 403 cooperate with the fourth bosses 603 to position the foolproof cap 6 outside the socket housing 4.

[0041] Refer to the attached Figure 1A energy storage connector includes: a plug connector 1 and a socket connector 2, the socket housing 4 of the socket connector 2 is axially fixedly connected to the plug housing 3 of the plug connector 1, the anti-foolproofing cap 6 of the socket connector 2 is circumferentially fixedly connected to the plug housing of the plug connector 1, and the socket housing 4 of the socket connector 2 is engaged with the anti-foolproofing cap 6. By rotating the socket connector 2 to adjust the engagement position of the socket housing 4 and the anti-foolproofing cap 6, the plug connector 1 can be rotated relative to the socket connector 2, ensuring that the arrangement angle of the plug connector 1 can be adjusted at multiple angles and avoiding shaking of the socket connector 2.

[0042] The fool-proof cap of the utility model can rotate circumferentially after being installed in the socket housing. The engagement of the anti-rotation key slot and the anti-rotation boss can provide a certain rotational resistance to lock the fool-proof cap, thereby allowing the plug connector to be maintained at a desired angle, thereby improving the stability of the electrical contact.

[0043] The hook of the plug connector of the utility model is integrally formed with the socket housing, which effectively improves the locking strength of the plug connector and the socket connector. A locking block is also designed in the plug connector to perform secondary locking of the hook, which can prevent the hook from being separated from the socket connector due to accidental contact or misoperation, and reduces the risk of the plug connector accidentally falling off from the socket connector.
