[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In order to solve the problem in the related art that an external force needs to be continuously input to keep the lock rotating in an unlocked state while being pulled apart in order to unplug the electrical connector, the embodiment of the utility model proposes an electrical connector that does not require continuous external force input when unlocking, and the electrical connector can be unplugged, which facilitates unlocking and improves the user experience.

[0019] Figure 1 The figure is a schematic structural diagram of an electrical connector according to an embodiment of the utility model.

[0020] Figure 2 The figure is a schematic structural diagram of a socket according to an embodiment of the utility model.

[0021] like Figure 1, Figure 2 As shown, the electrical connector comprises a lock catch 3 mounted on the socket 1 and at least one lock tongue 4 telescopically mounted on the plug 2. The lock catch 3 is rotatably sleeved on the socket 1 and a slot 5 for accommodating the lock tongue 4 is formed on the lock catch 3.

[0022] When the plug 2 and the socket 1 are in the plug-in state, the locking tongue 4 (under the compression of the lock catch 3 ) is retracted into the plug 2 and its position is offset from the notch 5 .

[0023] When the locking tongue 4 is aligned with the notch 5 , the locking tongue 1 extends from the plug 2 and into the notch 5 to limit the lock buckle 3 .

[0024] Specifically, the socket 1 and the plug 2 cooperate with each other to achieve connection and unlocking. The lock buckle 3 is a hollow tube and can be rotatably mounted on the plug 2. The lock tongue 4 can be telescopically installed on the socket 1. A slot 5 for accommodating the lock tongue 4 is provided on the lock buckle 3.

[0025] When connection is required, the plug 2 is inserted into the socket 1. During the insertion of the plug 2, the locking tongue 4 is compressed until it shrinks inside the plug 2. The plug 2 and the socket 1 are plugged in, that is, in an inserted state. In this state, the lock buckle 3 is in an initial position (the position of the lock buckle 3 refers to the position of the lock buckle 3 relative to the rotation direction of the socket 1), and the position of the locking tongue 4 is offset from the notch 5, so the locking tongue 4 is compressed and will not pop out.

[0026] When unlocking is required, the lock catch 3 is rotated. During the process of rotating the lock catch 3, when the lock tongue 4 is aligned with the notch 5, the lock tongue 4 pops out from the plug 2 and extends into the notch 5 to limit the lock catch 3 and restrict the lock catch 3 from returning to the initial position to prevent the socket 1 and the plug 2 from being plugged in again. At this time, there is no need to input external force to the lock catch 3 to rotate it. Instead, the lock catch 3 is kept in this position and the plug 2 is directly unplugged. During the unplugging process, the lock tongue 4 is still in the extended state, restricting the lock catch 3 from rotating. Until the socket 1 and the plug 2 are separated, the lock catch 3 returns to the initial position and the lock tongue 4 extends out of the plug 2.

[0027] In the related art, the requirement of continuous external force input often makes it difficult to unplug the plug 2 when the external force is insufficient, or the plug 2 is plugged in again due to the rotation of the lock catch 3 when it is halfway pulled out, resulting in a very poor user experience. However, due to the cooperation between the lock tongue 4 and the notch 5 of the utility model, in order to limit the rotation of the lock catch 3 when unlocking, there is no need to keep the lock catch 3 in a rotating state, and there is no need to continuously rotate the lock catch 3 while pulling out. Instead, the lock tongue 4 is extended into the notch 5 to limit the rotation of the lock catch 3, and the lock catch 3 is suspended at this position, thereby eliminating the need to continuously input external force to the lock catch 3, thereby avoiding the phenomenon that the electrical connector cannot be unplugged due to insufficient external force, interruption of external force, or loose rotation during the unlocking process. Moreover, suspending the lock catch does not affect the unlocking effect and facilitates unlocking.

[0028] Therefore, the electrical connector of the embodiment of the utility model uses the lock tongue and the slot to cooperate to limit the rotation of the lock when unlocking, and there is no need for the lock to rotate continuously, and there is no need to continuously input external force to the lock to achieve unlocking, thereby facilitating unlocking and improving the user experience.

[0029] In this example, the electrical connector further includes at least two sets of snap-fit ​​assemblies, referring to Figure 1 , Figure 2 Each set of buckle components includes a socket buckle 6 and a plug buckle 7 which cooperate with each other and are installed inside the socket 1 and the plug 2 respectively.

[0030] When the plug 2 and the socket 1 are in the plugged state, the socket buckle 6 and the plug buckle 7 are locked with each other to lock the plug 2 and the socket 1, and the socket buckle 6 and the corresponding plug buckle 7 are staggered to unlock.

[0031] Among them, the socket buckle 6 and the plug buckle 7 (also called male buckle and female buckle) are used to buckle with each other to achieve locking. The utility model does not limit their structure as long as they can buckle with each other.

[0032] Furthermore, when the locking tongue 4 is aligned with the notch 5, the socket buckle 6 is in a staggered state with the corresponding plug buckle 7. All the socket buckles 6 are evenly staggered in the circumferential direction inside the socket 1.

[0033] Reference Figure 2 , the electrical connector may also include:

[0034] A lock spring 8 is installed inside the socket 1, and the lock spring 8 is arranged along the circumferential direction inside the lock 3. When the plug 2 and the socket 1 are in the plugged state or the separated state, the lock 3 is kept in the initial position under the action of the lock spring 8;

[0035] A locking tongue spring is installed inside the plug 2 , and the locking tongue 4 extends out and into the slot 5 under the action of the locking tongue spring.

[0036] Specifically, after the plug 2 and the socket 1 are plugged together, the multiple sets of socket buckles 6 and plug buckles 7 are locked to prevent the plug 2 and the socket 1 from being loosened. At this time, the lock buckle 3 is in the initial position, and the lock buckle 3 can rotate clockwise within a fixed angle under the action of external force. When unlocking is required, the lock buckle 3 is rotated clockwise to stagger the socket buckle 6 and the corresponding plug buckle 7, and the plug 2 can be pulled out of the socket 1. Among them, when the lock buckle 3 is rotated, when the external force is interrupted and the lock tongue 4 has not yet aligned with the notch 5, the lock buckle 3 automatically returns to the initial position under the action of the lock buckle spring 8; the lock buckle 3 is continued to be rotated, and when the position of the lock tongue 4 is aligned with the notch 5, the lock tongue 4 pops out and extends into the notch 5 under the action of the lock tongue spring to limit the lock buckle 3 from returning to the initial position. At this time, the plug 2 can be pulled out without continuing to rotate the lock buckle 3, thereby achieving unlocking without continuously rotating the lock buckle 3.

[0037] Generally speaking, when the lock buckle 3 is rotated clockwise, the buckles that are locked or engaged with each other are first offset, and at the same time or after a period of time, the position of the lock tongue 4 is aligned with the notch 5, and the lock tongue 4 extends into the notch 5.

[0038] During the insertion process, the guide slopes of the socket buckle 6 and the corresponding plug buckle 7 are about to contact, and the lock buckle 3 is in the initial position. As the plug 2 is inserted, the lock buckle 3 rotates a certain angle under the action of the guide slope of the buckle, and the lock tongue 4 is compressed until it retracts into the plug 2. When the plug 2 is fully inserted, the buckle is buckled to lock the plug 2 and the socket 1. At the same time, the lock buckle 3 returns to the initial position under the action of the lock spring 8, and the plug 2 is plugged into the socket 1, and the electrical connector is locked.

[0039] like Figure 3 As shown, when the plug 2 and the socket 1 are plugged together, the socket buckle 6 and the corresponding plug buckle 7 are buckled together so that the plug 2 and the socket 1 cannot be separated. At this time, the lock tongue 4 is completely retracted in the plug 2, and the notch 5 is staggered with the lock tongue 4. When unlocking, the lock buckle 3 is slightly rotated clockwise. When the corresponding buckle has not been unhooked, it cannot be pulled out, and the notch 5 has not been aligned with the lock tongue 4. As long as the notch 5 has not reached the position of the lock tongue 4, the lock buckle 3 will return to the initial position under the action of the spring.

[0040] like Figure 4 As shown, continue to rotate the lock buckle 3 clockwise, the socket buckle 6 and the corresponding plug buckle 7 are staggered. Figure 3 On the basis of the above, if the lock is rotated further by an angle of about 20 to 30 degrees, the notch 5 is aligned with the lock tongue 4, so the lock tongue 4 pops out and extends into the notch 5. Even if the lock buckle 3 is released, the lock buckle 3 remains in this position and cannot be automatically rotated. Since the buckle position has been staggered, the plug 2 can be easily pulled out at this position without applying extra external force to the lock buckle 3. If the lock buckle 3 is rotated counterclockwise with a little force to disengage the notch 5 from the lock tongue 4, the lock buckle 3 will return to the initial position under the action of the spring.

[0041] like Figure 5 As shown, in Figure 4 On the basis of the lock catch 3 being suspended, the plug 2 is further pulled out, the lock tongue 4 is still in the extended state and gradually extends under the action of the lock tongue 4 spring, limiting the lock catch 3 from rotating, and the lock catch 3 remains in this position. If the plug 2 is further pulled out, when the plug 2 and the socket 1 are completely separated, the lock catch 3 will return to the initial position under the action of the lock catch spring 8, and the lock tongue 4 will return to the extended state under the action of the lock tongue 4 spring.

[0042] Generally, two or three pairs of socket buckles 6 and corresponding plug buckles 7 are designed to ensure that the restraining force is evenly distributed around the circumference when locked.

[0043] The shapes of the lock tongue 4 and the notch 5 are not limited to the triangular design shown in the figure, and other shapes such as a semicircle are also possible, as long as the lock tongue 4 can restrict the rotation of the lock buckle 3 after it is inserted into the notch 5. The position of the lock tongue 4 is not limited to the axial direction, as long as it can restrict the rotation of the lock buckle 3, facilitate the removal of the plug 2, and do not affect the lock buckle 3 from returning to the initial position after the plug 2 and the socket 1 are completely separated.

[0044] To sum up, the lock of the embodiment of the utility model can hover in the unlocking position of the electrical connector, and the electrical connector can be unplugged without continuously applying rotational force, which can avoid the problem of difficulty in unplugging due to insufficient rotational force, interrupted rotational force or loose rotation during unlocking. It is simple to use and easy to implement, and is convenient for unlocking. It can improve the user experience while ensuring the unlocking effect.
