[0002] Currently, an electronic connector (also often referred to as a circuit connector or electrical connector) is a conductor device that bridges two conductors in a loop so that current or signal can flow from one conductor to another.

[0003] This high-voltage, high-current connector is mainly used in energy storage systems. It can also be used to supply high-voltage current to pure electric vehicles, hybrid (electric) vehicles, fuel cell electric vehicles and other models; it is also suitable for connections between electrical systems of other industrial equipment.

[0004] The existing high-voltage and high-current connectors currently on the market usually include two plugs and sockets that are inserted into each other, a push-on locking switch, and a clamp is set at the connection between the plug and the socket. The clamp is pulled by the locking switch to unlock the plug and the socket at the connection. After multiple operations, the clamp is easy to bend and deform, and due to the setting of the clamp, the locking switch needs to be connected to the clamp. At the same time, the clamp as an additional part increases the assembly steps, resulting in inconvenience in operation. Utility Model Content

[0040] 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.

[0041] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0042] like Figure 1-12 As shown, a safety lock connector comprises: a plug assembly 1 and a socket assembly 2 plugged into each other, and an electrical connection assembly 3 arranged in the plug assembly 1 and the socket assembly 2, and also comprises a locking assembly, the locking assembly comprises a locking member 4, and a pressing portion 4.2 exposed outside the connector;

[0043] The locking member 4 has a locking position that blocks the separation path of the plug assembly 1 and locks the plug assembly 1 on the socket assembly 2, and the locking member 4 is moved to the unlocking position by actuating the pressing portion 4.2 to allow the plug assembly 1 to leave the socket assembly 2.

[0044] The socket assembly 2 is provided with a mounting cavity 2.2 for accommodating the locking assembly.

[0045] The utility model provides a locking member 4 in the socket assembly 2. Under normal conditions, the locking member 4 is retained in the space in the socket assembly 2 for the plug assembly 1 to be plugged in, unplugged and separated, thereby obstructing the separation path of the plug assembly 1, thereby achieving locking between the socket assembly 2 and the plug assembly 1 and stable matching of the electrical connection assembly 3 therebetween. When the lock needs to be released, the locking member 4 is driven to leave the separation path of the plug assembly 1 by actuating the pressing portion 4.2, and the plug assembly 1 can be pulled out at this time. The operation is simple and convenient.

[0046] like Figure 8 and Fig. 9 As shown, the above-mentioned electrical connection component 3 is usually a conductive column arranged in the plug component 1, and a conductive sleeve arranged in the socket component 2. The electrical connection component 3 realizes electrical connection when the plug component 1 and the socket component 2 are assembled in place. Of course, it can also be other forms of electrical connection components, which will not be elaborated here.

[0047] Specifically, from Figure 3 , Figure 5 , Figure 6 It can be seen that the locking member 4 always remains in the locked position when the button portion is released, that is, when no artificial unlocking force is applied to the pressing portion 4.2, the locking member 4 always remains locked, thereby stabilizing the state stability of the connector.

[0048] Among them, when the plug assembly 1 is not assembled to the socket assembly 2, the locking member 4 is also located in the assembly path of the plug assembly 1. At this time, the locking member 4 is pressed in the assembly path of the plug assembly 1, and then moved to the unlocked position by the force in the assembly direction.

[0049] As an example, the assembly path and the separation path are in opposite directions and are both located inside the socket assembly 2 .

[0050] The socket assembly 2 is provided with a connection seat 2.1 for inserting the plug assembly 1, an assembly path and a separation path of the plug assembly 1 are formed in the connection seat 2.1, and the locking member 4 is acted in the connection seat 2.1 to lock the plug assembly 1.

[0051] Reference Figure 3 , Figure 4 and Fig. 9 In the present embodiment, as an implementation mode in which the locking member 4 is moved to the unlocked position by the assembly action of the plug assembly 1, the locking member 4 is provided with a first guide surface 4.41 facing the assembly path of the plug assembly 1, and the first guide surface 4.41 is preferably arranged obliquely, and the plug assembly 1 abuts against the first guide surface 4.41 and drives the locking member 4 to move to the unlocked position.

[0052] The locking member 4 is provided with a locking surface 4.42 facing the separation path of the plug assembly 1. The locking surface 4.42 is preferably a plane, thereby effectively preventing the plug assembly 1 from being separated.

[0053] Of course, the first guide surface 4.41 mentioned above can be in other forms, and it only needs to provide a component force for guiding the force in the assembly direction of the plug assembly 1, and drive the locking member 4 away from the assembly path.

[0054] By providing a guide surface on the assembly path of the locking member 4 facing the plug assembly 1, when the plug assembly 1 is inserted into the socket assembly 2 from the outside, the assembly connection between the two and the conduction of the electrical connection assembly 3 can be achieved without operating the pressing portion 4.2.

[0055] like Figure 3 and Figure 4 In the embodiment, as an implementation method of the movement of the locking member 4 between the locking position and the unlocking position, the locking member 4 moves to the unlocking position along a swinging trajectory away from the action of the plug assembly 1. In order to compress the overall volume of the connector, a locking assembly is usually provided on one side of the connection portion between the plug assembly 1 and the socket assembly 2. Compared with setting the locking member 4 to a linear movement, the locking member 4 in this embodiment is a swinging movement, which is more conducive to space optimization and reduces the size of the connector occupied by the locking member 4 in the linear direction. At the same time, this setting method is more conducive to the locking member 4 to bear the pressure force of the plug assembly 1 from the assembly direction, forcing the locking member 4 to swing to the unlocking position. The reason is that for the linearly moving locking member 4, a resetting elastic member needs to be provided so that the locking member 4 can return to the locking position. When the plug assembly 1 is directly plugged in for assembly, it is also necessary to overcome the resistance from the elastic member. Therefore, by setting the locking member 4 to a swinging movement, the resistance of the elastic member can be better overcome.

[0056] It should be noted that the locking member 4 is restricted from swinging in the locked position, and when the pressing portion 4.2 is pressed by a finger, the locking member 4 can be driven to move, so as to allow the locking member 4 to swing to the unlocked position.

[0057] Based on the above embodiment, the locking member 4 is supported by a spring 7, and the spring 7 exerts a force to restore the locking member 4 to the locking position.

[0058] One end of the spring 7 abuts against the installation cavity 2 . 2 , and the other end abuts against the locking member 4 .

[0059] Preferably, the spring 7 is arranged to be parallel to the direction of the manual actuation pressing portion 4 . 2 , and the locking member 4 is abutted to the locking position with the action of the spring 7 and is in a posture parallel to the spring 7 .

[0060] Continue to refer to Figures 3 to 5Specifically, the spring 7 is arranged on one side of the pressing portion 4.2 and the locking piece 4, and the pressing portion 4.2 is arranged close to the locking piece 4, so that when the pressing portion 4.2 is pressed, one side of the locking piece 4 is abutted by the spring 7, and the side of the locking piece 4 corresponding to the pressing portion 4.2 is deflected toward one side of the spring 7 due to the pressing effect, thereby forcing the spring 7 to be compressed on one side of its axis to reduce the resistance of the spring 7 to the locking piece 4, while ensuring the restoring force of the spring 7 on the locking piece 4. When the plug assembly 1 is directly inserted into the socket assembly 2, the deflection of the locking piece 4 overcomes less resistance of the spring 7, making the direct insertion of the plug assembly 1 more convenient and quick, and when the locking piece 4 is moved from the locked position to the unlocked position through the pressing portion 4.2, it is also easier, thereby optimizing the overall operating feel.

[0061] Preferably, the locking member 4 is maintained in a linear posture parallel to the spring 7 in the locked position and is limited to swing. When the locking member 4 is moved under the action of the pressed portion 4.2, the locking member 4 is allowed to perform a swinging action.

[0062] like Figure 6 and Figure 7 As shown, based on the above, a limiting structure for keeping the locking member 4 in the locked position is further provided in the socket assembly 2 .

[0063] Specifically, the limiting structure includes a first limiting edge 2.4 and a second limiting edge 2.5 which are arranged on both sides corresponding to the main body 4.1 of the locking member 4. The first limiting edge 2.4 is arranged close to the plug assembly 1, and the second limiting edge 2.5 is arranged away from the plug assembly 1 corresponding to the swing direction of the locking member 4. The second limiting edge 2.5 is provided with an inclined surface 2.6 which is arranged opposite to the main body 4.1 of the locking member 4. A swing spacing is formed between the second limiting edge 2.5 and the locking member 4 for the locking member 4 to swing toward the second limiting edge 2.5. In the locked position, the locking member 4 is spaced apart from the inclined surfaces 2.6 on the second limiting edge 2.5, so that the locking member 4 and the second limiting edge 2.5 still maintain a straight limiting surface fit. When the locking member 4 is pressed, the locking member 4 is opposite to the inclined surfaces 2.6 on the second limiting edge 2.5. By swinging, the locking portion 4.4 on the locking member 4 is away from the separation path of the plug assembly 1, and the plug assembly 1 can be pulled out.

[0064] like Fig.11As shown, as a further embodiment of the locking member 4, the locking member 4 includes a rod-shaped main body 4.1, and a limiting portion 4.3 extending on one side of the end of the main body 4.1, a pressing portion 4.2 is arranged on the same side of the main body 4.1, and an abutment portion 4.5 for the spring 7 to be inserted is further provided on the limiting portion 4.3 at a distance from the main body 4.1, and a locking portion 4.4 is provided on the end of the main body 4.1 away from the pressing portion 4.2, and the locking portion 4.4 is placed in the separation path or the assembly path of the plug assembly 1.

[0065] like Figure 8 and Fig. 9 As shown, specifically, the socket assembly 2 is provided with a connecting seat 2.1 for inserting the plug assembly 1, the connecting seat 2.1 is provided with a slot, the locking member 4 is provided with a locking portion 4.4 passing through the slot and entering into the connecting seat 2.1, the locking portion 4.4 obstructs the separation path of the plug assembly 1, wherein the first guide surface 4.41 and the locking surface 4.42 are relatively arranged on the locking portion 4.4, and the locking portion 4.4 is away from the separation path of the plug assembly 1 in the unlocked position.

[0066] like Fig.10 As shown, specifically, a second guide surface 4.43 is provided on the slot and / or the locking part 4.4. The second guide surface 4.43 is set corresponding to the pressing direction of the pressing part 4.2, and guides the locking part 4.4 to move to the unlocking position. When the locking member 4 is pressed, the locking member 4 will still produce a stroke movement in the pressing direction. Through the setting of the second guide surface 4.43, it is ensured that the locking member 4 can be deflected away from the separation path of the plug assembly 1 during the pressing process, so that the unlocking action is smoother.

[0067] Reference Figures 3 to 7 Specifically, the socket assembly 2 is provided with an installation cavity 2.2 for accommodating the locking assembly, and a limiting rib 2.3 is provided in the installation cavity 2.2. The limiting rib 2.3 separates the installation cavity 2.2 and forms a first area and a second area 6. The locking member 4 is constrained to deflect in the first area, and the spring 7 is confined in the second area 6.

[0068] Among them, the limiting rib 2.3 is arranged in an L shape, the limiting rib 2.3 constitutes the above-mentioned limiting structure, and the second limiting edge 2.5 and the inclined surface 2.6 are arranged on the limiting rib 2.3, and correspond to one side boundary of the first area, the first limiting edge 2.4 corresponds to the other side boundary of the first area, and forms a space in the first area for the locking member 4 to swing after being pressed, thereby realizing the limitation of the locking member 4 between the locking position and the unlocking position.

[0069] The limiting rib 2.3 constitutes one side of the second area 6, the mounting cavity 2.2 constitutes the other side of the second area 6, and the limiting rib 2.3 is also provided with a bottom edge corresponding to the second area 6, so as to limit the radial and axial directions of the spring 7. On the basis of inserting the spring 7 into the positioning portion as mentioned above, the position stability of the spring 7 in the mounting cavity 2.2 is ensured.

[0070] In other embodiments, the limiting structure further includes a supporting rib 2.9 disposed in the mounting cavity 2.2. In the locked position, the locking portion 4.4 of the locking member 4 is linearly fitted with the supporting rib 2.9, thereby preventing the locking member 4 from swinging. Figure 6 The dotted line in the middle is the support rib 2.9 position. Fig.10 The constraint of the locking member 4 by the supporting rib 2.9 can be further seen in FIG.

[0071] As a further implementation of the installation cavity 2.2, one end of the installation cavity 2.2 is open, the locking member 4 has a limiting portion 4.3 abutted against the connecting wall 2.21 of the installation cavity 2.2, the pressing portion 4.2 is penetrated through the connecting wall 2.21 of the installation cavity 2.2, and the limiting rib 2.3 corresponds to the end between the pressing portion 4.2, and a movable gap 9 is provided between the limiting rib 2.3 and the connecting wall 2.21 of the installation cavity 2.2 for the locking member 4 to move between the locking position and the unlocking position.

[0072] Specifically, the movable gap 9 is used to allow the pressing part 4.2 to move between the locking position and the unlocking position.

[0073] By improving the mounting cavity 2.2, the locking member 4 can be pre-positioned in the mounting cavity 2.2 through the pressing portion 4.2 and the locking portion 4.4, so that the spring 7 can be more easily and quickly fitted between the locking member 4 and the socket assembly 2. At the same time, the mounting cavity 2.2 with one end open further expands the assembly space of the locking member 4.

[0074] like Figure 5 and Fig.12 As shown, on the basis of the above embodiment, a protective cover 8 is further closed outside the installation cavity 2.2, so as to shield the locking member 4 and the spring 7 and play a protective role.

[0075] Specifically, the contour of the protective cover 8 matches the contour of the installation cavity 2.2, and two bosses 2.7 are provided on the limiting rib 2.3. The two bosses 2.7 are plug-fitted with the protective cover 8 through interference fit, and the assembly direction of the protective cover 8 is defined.

[0076] In addition, a buckle platform 2.8 in the same direction as the assembly direction of the protective cover 8 is provided on the open side corresponding to the installation cavity 2.2, and a buckle groove 8.1 cooperating with the buckle platform 2.8 is provided on the protective cover 8, so that the protective cover 8 is limited on the socket assembly 2 by snapping.

[0077] Among them, a recessed portion is provided on the socket assembly 2 corresponding to the pressing portion 4.2, and the recessed portion is preferably arc-shaped to adapt to the shape of the finger, while increasing the actuating stroke of the pressing portion 4.2, which is convenient for operation.

[0078] Reference Figure 8 and Fig. 9 In the above embodiment, a protruding ring 1.1 is provided on the plug assembly 1 and is inserted into the socket assembly 2. The locking member 4 acts on the protruding ring 1.1 to prevent the plug assembly 1 from being separated from the socket assembly 2.

[0079] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
