Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and more particularly to a connector capable of being unlocked obliquely. Background Art

[0002] Due to the frequent accidents of new energy small vehicles on the market, the state's control system for new energy vehicles has become increasingly strict; at the same time, as people rely more and more on new energy two-wheelers for travel, how to safely and quickly connect to the power supply has become the key to the development of existing new energy vehicles. Inspired by this, some new energy companies have begun to experiment with battery replacement models.

[0003] The connectors currently used in the battery swap market are divided into direct plug-in and non-locking structures and locking structures. The unlocking structures are mostly rotation unlocking, thread unlocking, and unlocking with the help of other structures. Rotation unlocking requires twisting the rotating cover to compress the locking spring inside the cover, causing the locking block to shift and leave the locking slot, while applying force to pull the connector outward.

[0004] Thread unlocking refers to an external thread locking structure. When plugging in, you need to lock the thread after the connector structure is connected, and open the thread before unlocking. Other unlocking methods require the use of some buckle structure, which can only be unlocked by pressing the buckle.

[0005] At present, connectors without locking structures often rely on a large plug-in and pull-out force to provide stable contact between terminals, which makes them feel bad to use. At the same time, connectors without locking structures are at risk of poor contact during severe bumps. Connectors with locking structures require users to master their unlocking methods, which is relatively time-consuming and labor-intensive for users in the battery swap market and does not conform to usage habits. In addition, it is difficult for users to unlock the device without understanding the unlocking method, so they may forcefully unlock the device, damaging the structure of the connector, which may easily lead to unstable connector contact and battery burns.

[0006] In summary, how to solve the problem that it is time-consuming and laborious to unlock a connector with a locking structure and that a connector without a locking structure has poor contact is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0007] In view of this, an object of the present invention is to provide a connector with an oblique unlocking function, wherein the second end connector and the first end connector are firmly connected and can be easily disassembled.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0024] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0025] The core of the present invention is to provide a connector that can be unlocked obliquely, and the connection between the second end connector and the first end connector is stable and easy to disassemble.

[0026] Please refer to Figures 1-2 , a connector for oblique unlocking, comprising a first end connector and a second end connector, wherein the second end connector is configured to be matched and inserted into the first end connector; characterized in that an elastic member 3 is provided between the first end connector and the second end connector, a first clamping portion is provided in the first end connector, and a second clamping portion is provided in the second end connector; the elastic member 3 and the second clamping portion are provided on different planes;

[0027] When the second end connector is inserted into the first end connector, the elastic member 3 is compressed to engage the first clamping portion with the second clamping portion; when the second end connector is subjected to a pulling force, the elastic member 3 is compressed to unlock the first clamping portion with the second clamping portion.

[0028] It should be noted that after the second end connector is inserted into the first end connector, the second end connector and the first end connector can transmit signals. After the second end connector is pulled out along the first end connector, the second end connector and the first end connector disconnect communication. The first end connector is divided into a head and a tail. The tail of the first end connector is connected to the components in the device, and the head of the first end connector is exposed from the device as a fixed plug-in terminal. The second end connector is divided into a head and a tail. The tail of the second end connector is connected to the wire, and the head of the second end connector forms a movable plug-in terminal.

[0029] A second clamping portion is arranged on the outer periphery of the second end connector, and the insertion direction of the second end connector into the first end connector can be straight insertion or oblique insertion, and the angle of the oblique insertion is greater than the angle at which the second end connector is obliquely pulled out when the second end connector is subjected to a pulling force. When the second end connector is inserted along the first end connector, the second clamping portion will gradually approach the first clamping portion. When the signals of the second end connector and the first end connector are connected, the first clamping portion and the second clamping portion are clamped with each other. When removing, the clamping of the first clamping portion and the second clamping portion can be released.

[0030] The obliquely unlocked connector provided by the present application is clamped by the elastic member 3 so that the first clamping part and the second clamping part are mutually clamped, so that the second end connector can be stably inserted into the first end connector to ensure the stability of signal transmission; when unplugging, the first clamping end and the second clamping end can only be released when the second end connector is subjected to a pulling force. The obliquely unlocked connector has a simple structure, is easy to process, has a low cost, is easy to unlock, and avoids forced unlocking to damage the connector structure.

[0031] When the connector with oblique unlocking is in use, the first end connector and the second end connector are plugged in and locked in a forward direction; when the connector with oblique unlocking is unlocked, the first end connector and the second end connector are in a locked state when being pulled out in a forward direction and cannot be unlocked, and need to be pulled out in an oblique direction to be unlocked.

[0032] On the basis of the above embodiment, as a further preference, the elastic member 3 is arranged on the second end connector, or arranged on the first end connector, or arranged independently. The structure and actual installation position of the elastic member 3 can be set according to the actual application situation. When the elastic member 3 is arranged independently, the elastic member 3 is not connected to the first end connector and the second end connector.

[0033] Regarding the structural form of the first end connector, based on the above embodiment, as a further preference, the first end connector includes a first housing 1, a first fixing member 2 and a first end connector sub-9, the first fixing member 2 is arranged in the first housing 1, the first end connector sub-9 is arranged on the first fixing member 2, and the first clamping portion is arranged at the bottom of the first housing 1. The first housing 1 is a cylindrical structure, and an annular mounting platform is arranged on the outer periphery. At least one screw hole is arranged on the mounting platform to mount the first housing 1 on the equipment by bolts. The first housing 1 is sleeved on the outside of the first fixing member 2, the first fixing member 2 is used to fix the position of the first end connector sub-9, and the first clamping portion is arranged at the bottom of the side wall of the cylindrical structure of the first housing 1.

[0034] Regarding the selection of the first clamping part, on the basis of the above embodiment, as a further preference, the first clamping part is a clamping hole 10 arranged at the bottom of the first shell 1. The clamping hole 10 is a hole that penetrates the side wall of the first shell 1. The size and shape of the hole can be set according to the structural shape of the second clamping part. In order to facilitate unlocking, the clamping hole 10 is set on the side wall of the first shell 1 outside the annular mounting platform. After the second clamping part is clamped into the clamping hole 10, the position of the second clamping part is fixed under the limiting effect of the side wall of the clamping hole 10, so that it cannot be unlocked in the horizontal direction. When unlocking, the second clamping part is pushed out of the clamping hole 10 and then moved horizontally; or the second end connector is moved vertically to make the second clamping part leave the clamping hole 10; or the second end connector can be pulled out by applying a force obliquely outward and upward to the second end connector without disassembling the first end connector.

[0035] Regarding the structural form of the second end connector, on the basis of the above embodiment, as a further preference, the second end connector includes a second housing 6, a second fixing member 7 and a second end connector sub-5, the second fixing member 7 is arranged in the second housing 6, the second end connector sub-5 is arranged on the second fixing member 7, and the second clamping portion is arranged at the lower part of the second fixing member 7. The second clamping portion is arranged at the outer peripheral bottom of the second housing 6, so that the positions of the second clamping portion and the first clamping portion correspond to each other. It should be specially explained here that the first clamping portion is not limited to being arranged at the bottom of the first housing 1, and the second clamping portion is not limited to being arranged at the lower part of the second housing 6. As long as the positions of the first clamping portion and the second clamping portion correspond to each other, after the second end connector is inserted into the first end connector, the first clamping portion and the second clamping portion can be clamped with each other.

[0036] Regarding the selection of the second clamping part, on the basis of the above embodiment, as a further preference, the second clamping part is a lock hook 8 arranged at the bottom of the locking kit 4. When the second end connector is inserted into the first end connector, the lock hook 8 is clamped into the clamping hole 10, and the locking kit 4 is sleeved on the second fixing member 7 protruding from the second housing 6. Since the lock hook 8 is a wearing part, if it is directly arranged on the periphery of the second fixing member 7, when the lock hook 8 is damaged and needs to be replaced, the second fixing member 7 needs to be replaced as a whole, which increases the cost and working hours. In order to solve this problem, in this embodiment, the locking kit 4 is sleeved on the outside of the second fixing member 7, and the lock hook 8 is arranged on the bottom periphery of the locking kit 4. The locking kit 4 and the second fixing member 7 are interference fit. When the lock hook 8 fails, the locking kit 4 can be removed for replacement without replacing the second fixing member 7.

[0037] When the second-end connector is not inserted into the first-end connector, the elastic member 3 is in a state of protruding upward along the locking kit 4. When the second-end connector is gradually inserted into the first-end connector, the top surface of the inner wall of the first shell 1 will press the elastic member 3 downward, and under the support of the inner wall bottom surface of the first shell 1 on the lock hook 8, the elastic member 3 is compressed until the lock hook 8 enters the snap-in hole 10, and the elastic member 3 recovers part of its deformation, but is still in an elastically compressed state. When unlocking, the second shell 6 is moved upward to further compress the elastic member 3 until the lock hook 8 leaves the snap-in hole 10, and then the second-end connector can be pulled out horizontally; or when a force is applied to the second shell 6 obliquely to the outside and upward, the elastic member 3 can also be compressed to make the lock hook 8 leave the snap-in hole 10 for unlocking.

[0038] The present application forms a new locking structure by combining rigid locking with elastic unlocking, which can ensure that the connector product will not fall out during use and ensure a reliable connection; however, when the connector is subjected to oblique force, the second end connector can be easily pulled out.

[0039] Since the locking kit 4, the lock hook 8 and the elastic member 3 are consumable parts, fatigue fracture may easily occur after long-term use. In order to increase the service life of the locking kit 4, the lock hook 8 and the elastic member 3, on the basis of the above embodiment, as a further preference, the locking kit 4 is a metal part, the lock hook 8 is a metal lock hook, and the elastic member 3 is a metal locking member.

[0040] Regarding the selection of materials for the first fixing member 2 and the second fixing member 7, based on the above embodiment, as a further preference, the first fixing member 2 and the second fixing member 7 are both plastic parts, which are low in cost, easy to process, easy to install, and lightweight.

[0041] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0042] The above is a detailed introduction to the oblique unlocking connector provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
