Description

Technical Field

[0001] This utility model relates to the field of plug-in connection equipment technology, and in particular to a connector and a vehicle. Background Technology

[0002] In related technologies, wires are often electrically connected through connectors. A connector includes a male plug and a female socket. The male plug includes a male terminal and a plug housing, and the female socket includes a female terminal and a socket housing. The male terminal and the female terminal are plugged into each other to realize the electrical connection function of the connector.

[0003] In related technologies, in the insertion direction of the male plug and female socket, a limiting structure is provided on the side of the plug shell near the female socket, and correspondingly, a limiting structure is provided on the side of the socket shell near the male plug. During the insertion process of the male and female terminals, the limiting structures on the plug shell and the socket shell simultaneously engage. However, in the insertion direction of the plug and socket shells, because the limiting structures themselves occupy a large space, the engagement method of the limiting structures on the plug shell and the socket shell results in a large mating gap between them after insertion. Dust, water, and other impurities can enter the contact interface between the male and female terminals through this gap, leading to poor contact or even short circuits, affecting the overall reliability of the connector. Therefore, this issue needs to be addressed. Utility Model Content

[0054] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0055] The following is for reference. Figures 1-15 A connector 100 according to an embodiment of the present utility model is described.

[0056] Reference Figure 1 , Figure 7 and Figure 11 According to a first aspect of the present invention, a connector 100 includes a male plug 1, a female socket 2, and a connecting cover 3. The male plug 1 includes a plug shell 11 and a male terminal assembly 12, with the plug shell 11 sleeved on the outer periphery of the male terminal assembly 12. The female socket 2 includes a socket shell 21 and a female terminal assembly 22, with the socket shell 21 sleeved on the outer periphery of the female terminal assembly 22, and the female terminal assembly 22 being plugged into and connected to the male terminal assembly 22. The connecting cover 3 is located outside the plug shell 11 and the socket shell 21, and the connecting cover 3 is detachably connected to at least one of the plug shell 11 and the socket shell 21.

[0057] For example, the male plug 1 includes a male wire 13, the male terminal assembly 12 includes a male terminal 121, the male wire 13 is electrically connected to the male terminal 121, the female socket 2 includes a female wire 23, the female terminal assembly 21 includes a female terminal 221, the female wire 23 is electrically connected to the female terminal 221, and the male terminal 121 and the female terminal 221 are connected by plugging in the male terminal 121 and the female terminal 221, thereby realizing the electrical connection between the male wire 13 and the female wire 23.

[0058] The plug housing 11 supports and fixes the male terminal assembly 12. By fitting the plug housing 11 around the outer periphery of the male terminal assembly 12, it protects the male terminal assembly 12. The socket housing 21 supports and fixes the female terminal assembly 22. By fitting the socket housing 21 around the outer periphery of the female terminal assembly 22, it protects the female terminal assembly 22.

[0059] The connecting cover 3 is located on the outside of the plug housing 11 and the socket housing 21, providing support and protection for them to prevent damage from external impacts. The connecting cover 3 is snap-fitted to both the plug housing 11 and the socket housing 21, making the connection simple and stable. Furthermore, the connecting cover 3 can be detachably connected to both the plug housing 11 and the socket housing 21, allowing for a simpler connection between them. This reduces the assembly difficulty between the male plug 1 and the female socket 2, and also enhances the connection stability between the plug housing 11 and the socket housing 21. Furthermore, at least part of the connecting cover 3 can block the mating gap between the plug housing 11 and the socket housing 21, thereby reducing the possibility of dust entering the contact interface between the male terminal assembly 12 and the female terminal assembly 22 through this gap, resulting in poor contact, or water entering the contact interface between the male terminal assembly 12 and the female terminal assembly 22 through this gap, resulting in a short circuit. This is beneficial to enhancing the overall reliability of the connector 100.

[0060] For example, the assembly process of the male plug 1, the female socket 2, and the connecting cover 3 can be as follows: first, the male terminal 121 and the female terminal 221 are plugged in to achieve electrical connection between the male terminal 121 and the female terminal 221, and then the connection between the socket shell 21 and the plug shell 11 is achieved through the connecting cover 3 to ensure accurate assembly position between the male terminal 121 and the female terminal 221, and to enhance the connection stability between the socket shell 21 and the plug shell 11.

[0061] According to the connector 100 of this utility model embodiment, the connecting cover 3 is located outside the plug shell 11 and the socket shell 21, and the connecting cover 3 is detachably connected to at least one of the plug shell 11 and the socket shell 21. The connecting cover 3 can provide a certain degree of support and protection for the plug shell 11 and the socket shell 21. Furthermore, this can enhance the connection stability between the plug shell 11 and the socket shell 21. At least a portion of the connecting cover 3 can cover the mating gap between the plug shell 11 and the socket shell 21, thereby reducing the possibility of dust, water, etc. entering the contact interface between the male terminal 121 assembly 12 and the female terminal 221 assembly 22 through the mating gap between the plug shell 11 and the socket shell 21, which may lead to poor contact or short circuit. This is beneficial to enhancing the overall reliability of the connector 100.

[0062] Reference Figure 5 , Figure 6 , Figure 7 and Figure 11According to some embodiments of the present invention, the female terminal assembly 22 and the male terminal assembly 12 are adapted to be aligned along a first direction (e.g., see reference to...). Figure 1 In the first direction (e1 direction), the male terminal assembly 12 protrudes from the plug housing 11, and the protruding part of the male terminal assembly 12 is the male plug portion 122. The male plug portion 122 is inserted into the female terminal assembly 22 in the first direction. The male plug portion 122 protrudes from the plug housing 11 in the first direction. In the plugging direction of the female terminal assembly 22 and the male terminal assembly 12, compared with at least a part of the socket housing 21 being connected to at least a part of the plug housing 11 by an interlocking manner, the plugging difficulty between the male plug 1 and the female socket 2 can be reduced, making the plugging between the male plug portion 122 and the female terminal assembly 22 smoother and more convenient.

[0063] For example, the first direction intersects with the outer peripheral direction of the socket housing 21 or the plug housing 11, and the first direction can be orthogonal to the outer peripheral direction of the socket housing 21 or the plug housing 11.

[0064] Reference Figure 5 , Figure 6 , Figure 7 and Figure 11 According to some embodiments of the present invention, in a first direction, the end face of the plug shell 11 facing the socket shell 21 is a first end face 111, and the end face of the socket shell 21 facing the plug shell 11 is a second end face 211. The male plug portion 122 protrudes from the first end face 111 in the first direction, and the first end face 111 and the second end face 211 are opposite each other. Since the male plug portion 122 protrudes from the first end face 111 in the first direction, and the first end face 111 and the second end face 211 are opposite each other, in the insertion direction of the female terminal assembly 22 and the male terminal assembly 12, compared to at least a portion of the socket shell 21 being connected to at least a portion of the plug shell 11 by an interlocking manner, the insertion difficulty between the male plug 1 and the female socket 2 can be reduced, further making the insertion between the male plug portion 122 and the female terminal assembly 22 smoother and more convenient.

[0065] Reference Figure 2 , Figure 5 and Figure 6 According to some embodiments of the present invention, the first end face 111 and the second end face 211 are fitted together, which can make the plug shell 11 and the socket shell 21 fit together in the first direction. This can make the gap between the plug shell 11 and the socket shell 21 as small as possible, and make the overall structure of the plug shell 11 and the socket shell 21 more compact, so as to reduce the space occupied by the connector 100 in the first direction.

[0066] Reference Figure 1 , Figure 2 , Figure 14 and Figure 15According to some embodiments of the present invention, the connecting cover 3 has a receiving groove 31, and at least a portion of the plug shell 11 and the socket shell 21 are located within the receiving groove 31. The at least a portion of the plug shell 11 and the socket shell 21 being located within the receiving groove 31 can include the following situations: for example, a portion of the plug shell 11 and the socket shell 21 may be located within the receiving groove 31; or, for another example, the entire plug shell 11 and the socket shell 21 may be located within the receiving groove 31.

[0067] At least a portion of the plug housing 11 and the socket housing 21 are located within the receiving groove 31, which allows for a more compact overall structure of the plug housing 11, the socket housing 21, and the connecting cover 3. Additionally, for example, the outer peripheral wall of the plug housing 11 and / or the socket housing 21 can abut against the inner peripheral wall of the receiving groove 21. This can limit the relative movement between the plug housing 11 and the socket housing 21 and the connecting cover 3, reducing or preventing the possibility of relative movement between the plug housing 11 or the socket housing 21 and the connecting cover 3 along the first or second direction.

[0068] Reference Figure 1 , Figure 2 , Figure 14 and Figure 15 According to some embodiments of this utility model, there are two connecting covers 3. The plug shell 11 and the socket shell 21 are both accommodated in the receiving cavity defined by the two connecting covers 3. The receiving grooves 31 of the two connecting covers 3 together constitute the receiving cavity. The receiving cavity facilitates the insertion of the plug shell 11 and the socket shell 21. Moreover, the two connecting covers 3 jointly defining the receiving cavity allows for step-by-step assembly between the plug shell 11 and the socket shell 21 and the two connecting covers 3, making the assembly between the plug shell 11 and the socket shell 21 and the connecting covers 3 more convenient and reducing the assembly difficulty between the plug shell 11 and the socket shell 21 and the two connecting covers 3.

[0069] For example, the assembly process of the plug shell 11 and the socket shell 21 with the two connecting covers 3 can be as follows: first, the plug shell 11 and the socket shell 21 are placed into the receiving groove 31 of one of the connecting covers 3. At this time, the assembly position of the plug shell 11 and the socket shell 21 on the connecting cover 3 can be initially determined. Then, the other connecting cover 3 is assembled onto the plug shell 11, the socket shell 21 and one of the connecting covers 3, thereby completing the assembly process of the plug shell 11 and the socket shell 21 with the two connecting covers 3.

[0070] Reference Figure 1 , Figure 2 , Figure 5 , Figure 14 and Figure 15According to some embodiments of the present invention, the male plug 1 includes a male wire 13, the male terminal assembly 12 includes a male terminal 121, the male wire 13 is connected to the male terminal 121, the female socket 2 includes a female wire 23, the female terminal assembly 22 includes a female terminal 221, the female wire 23 is connected to the female terminal 221, the female terminal assembly 22 and the male terminal assembly 12 are adapted to be plugged into each other along a first direction, there are two connecting covers 3, each connecting cover 3 has a first wire notch 321 and a second wire notch 322 formed on opposite sides along the first direction, the first wire notches 321 of the two connecting covers 3 are joined to form a first wire hole 323, the male wire 13 passes through the first wire hole 323, the second wire notches 322 of the two connecting covers 3 are joined to form a second wire hole 324, the female wire 23 passes through the second wire hole 324.

[0071] The first wire through hole 323 can limit the movement of the male wire 13, reducing the possibility of the male wire 13 swinging significantly, thereby reducing the possibility of the male wire 13 causing the male terminal 121 to tilt or swing, and thus reducing the frictional wear at the contact point between the male terminal 121 and the female terminal 221 caused by the tilting or swinging of the male terminal 121. The second wire through hole 324 can limit the movement of the female wire 23, reducing the possibility of the female wire 23 swinging significantly, thereby reducing the possibility of the female wire 23 causing the female terminal 221 to tilt or swing, and thus reducing the frictional wear at the contact point between the male terminal 121 and the female terminal 221 caused by the tilting or swinging of the female terminal 221.

[0072] Reference Figure 1 , Figure 2 , Figure 14 and Figure 15 According to some embodiments of this utility model, the male wire 13 is fitted with the first wire passage hole 323 with a clearance fit. This makes the connection between the male wire 13 and the two connecting covers 3 simple and has strong stability. By fitting the male wire 13 with the first wire passage hole 323 with a clearance fit, the gap between the male wire 13 and the first wire passage hole 323 can be smaller, so as to reduce or avoid dust, water, etc. entering the receiving cavity through the gap between the first wire passage hole 323. At the same time, it can facilitate the male wire 13 to pass through the first wire passage hole 323, making the assembly between the male wire 13 and the connecting cover 3 more convenient. Moreover, the clearance fit between the male wire 13 and the first wire passage hole 323 allows the first wire passage hole 323 to be suitable for male wires 13 of different sizes, thus enhancing the adaptability of the connecting cover 3.

[0073] Reference Figure 1 , Figure 2 , Figure 14 and Figure 15According to some embodiments of this utility model, the female end wire 23 and the second wire passage hole 324 are fitted with a clearance, which can make the gap between the female end wire 23 and the second wire passage hole 324 smaller. This reduces or prevents dust, water, etc. from entering the receiving cavity through the gap between the second wire passage hole 324. At the same time, it facilitates the passage of the female end wire 23 through the second wire passage hole 324, making the assembly between the female end wire 23 and the connecting cover 3 more convenient. Furthermore, the clearance fit between the female end wire 23 and the second wire passage hole 324 allows the second wire passage hole 324 to be used for female end wires 23 of different sizes, thus enhancing the adaptability of the connecting cover 3.

[0074] Reference Figure 1 , Figure 2 , Figure 14 and Figure 15 According to some embodiments of this utility model, the inner periphery of both the first wire-passing hole 323 and the second wire-passing hole 324 is rounded. The rounded corners allow the inner periphery of the first wire-passing hole 323 and the hole wall surface, as well as the inner periphery of the second wire-passing hole 324 and the hole wall surface, to smoothly transition. This reduces friction and wear on the male wire 13 and the female wire 23 when the male wire 13 passes through the first wire-passing hole 323 and the female wire 23 passes through the second wire-passing hole 324, which is caused by the excessive sharpness at the connection between the inner periphery of the first wire-passing hole 323 and the hole wall surface, as well as the inner periphery of the second wire-passing hole 324 and the hole wall surface. This helps to extend the service life of the male wire 13 and the female wire 23.

[0075] Reference Figure 7 and Figure 9 According to some embodiments of the present invention, in the first direction, a first cable outlet 14 is formed on the side of the plug housing 11 opposite to the socket housing 21, and a second cable outlet is formed on the side of the socket housing 21 opposite to the plug housing 11. The first cable outlet 14 corresponds to the first cable through hole 323. The male wire 13 exits through the first cable outlet 14 and the first cable through hole 323. The second cable outlet corresponds to the second cable through hole 324, and the female wire 23 exits through the second cable outlet and the second cable through hole 324. The first cable outlet and the first cable through hole 323 facilitate the exit of the male wire 13, and the second cable outlet and the second cable through hole 324 facilitate the exit of the female wire 23. Furthermore, the correspondence between the first cable outlet 14 and the first cable through hole 323, and the correspondence between the second cable outlet and the second cable through hole 324, makes the routing of the male wire 13 and the female wire 23 more orderly, which is beneficial to the layout optimization within the connector 100.

[0076] Reference Figure 7 and Figure 9According to some embodiments of the present invention, the projection of the first wire through hole 323 on the reference surface is located within the projection of the corresponding first wire outlet 14 on the reference surface, and the projection of the second wire through hole 324 on the reference surface is located within the projection of the corresponding second wire outlet on the reference surface, and the reference surface is perpendicular to the first direction. By having the first outlet 14 correspond to the first wire passage hole 323, and the projection of the first wire passage hole 323 on the reference plane being located within the projection of the corresponding first outlet 14 on the reference plane, it can be ensured that the gap between the inner peripheral wall of the first wire passage hole 323 and the outer peripheral wall of the male wire 13 is smaller than the gap between the inner peripheral wall of the first outlet 14 and the outer peripheral wall of the male wire 13. This can effectively reduce or prevent dust, water, etc. from entering the receiving cavity through the first wire passage hole 323 or the second wire passage hole 324, and then entering the first outlet 14 through the receiving cavity. By making the gap between the outer peripheral wall of the male wire 13 and the inner peripheral wall of the first wire passage hole 323 as small as possible, the male terminal 121 in the receiving cavity can be protected, thereby enhancing the reliability of the male terminal 121.

[0077] By aligning the second outlet with the second wire passage hole 324 and ensuring that the projection of the second wire passage hole 324 onto the reference plane lies within the projection of the corresponding second outlet onto the reference plane, it can be ensured that the gap between the inner peripheral wall of the second wire passage hole 324 and the outer peripheral wall of the female terminal wire 23 is smaller than the gap between the inner peripheral wall of the second outlet and the outer peripheral wall of the female terminal wire 23. This effectively reduces or prevents dust, water, etc., from entering the receiving cavity through the second wire passage hole 324 and subsequently the second outlet through the receiving cavity. By minimizing the gap between the outer peripheral wall of the female terminal wire 23 and the inner peripheral wall of the second wire passage hole 324, the female terminal 221 within the receiving cavity can be protected, thereby enhancing the reliability of the female terminal 221.

[0078] Reference Figure 1 , Figure 7 and Figure 8 According to some embodiments of this utility model, both the first wire passage hole 323 and the second wire passage hole 324 are circular, and both the first wire outlet 14 and the second wire outlet are square. Since the cross-sections of the male wire 13 and the female wire 23 are circular, compared to the square first wire outlet 14 and the second wire outlet, the inner peripheral walls of the circular first wire passage hole 323 and the second wire passage hole 324 can fit more closely to the outer peripheral walls of the male wire 13 and the female wire 23. This allows the gaps between the male wire 13 and the first wire passage hole 323, and between the female wire 23 and the second wire passage hole 324, to be as small as possible, thereby reducing or preventing external dust, water, etc. from entering the first wire outlet 14 or the second wire outlet through the gap between the first wire passage hole 323 and the male wire 13 or the second wire passage hole 324 and the female wire 23.

[0079] Reference Figure 6 , Figure 14 and Figure 15 According to some embodiments of the present invention, the connecting cover 3 is snapped together with the plug shell 11 and the socket shell 21, which enables a detachable connection between the connecting cover 3 and the plug shell 11 and the socket shell 21, facilitating the maintenance or replacement of the connecting cover 3, the plug shell 11, or the socket shell 21.

[0080] Reference Figure 6 , Figure 14 and Figure 15 According to some embodiments of this utility model, the connecting cover 3 has a locking hole 331, and both the socket shell 21 and the plug shell 11 are provided with buckles that engage with the locking hole 331. By engaging the buckles with the locking hole 331, a snap-fit ​​connection can be achieved between the connecting cover 3 and the socket shell 21 and the plug shell 11.

[0081] Reference Figure 6 , Figure 7 , Figure 9 and Figure 13 According to some embodiments of the present invention, the buckle is provided on the outer periphery of the plug housing 11 and the outer periphery of the socket housing 21, which makes the assembly between the plug housing 11 and the socket housing 21 and the connecting cover 3 simpler and can avoid affecting the plugging operation between the male terminal 121 and the female terminal 221.

[0082] For example, if the latch is located in the insertion direction of the plug housing 11 and the socket housing 21, when the plug housing 11 and the socket housing 21 are oriented towards each other to facilitate the insertion of the male terminal 121 and the female terminal 221, the latch located in the insertion direction will hinder the connection between the plug housing 11 and the socket housing 21, thereby increasing the assembly difficulty between the plug housing 11 and the socket housing 21 and the connecting cover 3. By setting the latch on the outer periphery of the plug housing 11 and the outer periphery of the socket housing 21, the latching connection between the socket housing 21 and the plug housing 11 and the connecting cover 3 can be achieved without affecting the insertion operation between the male terminal 121 and the female terminal 221.

[0083] Reference Figure 5 , Figure 9 and Figure 13 According to some embodiments of the present invention, the male terminal 121 and the female terminal 221 are adapted to be inserted and connected along a first direction, and both the male terminal 121 and the female terminal 221 are along a second direction (for example, refer to...). Figure 1The plug housing 11 includes two first sidewalls 15 arranged opposite each other along the second direction (e2 direction), and the socket housing 21 includes two second sidewalls 25 arranged opposite each other along the second direction. A snap fastener is provided on the first sidewalls 15 and the second sidewalls 25. The second direction intersects the first direction. In the description of this utility model, "multiple" means two or more.

[0084] There are multiple male terminals 121 and multiple female terminals 221. Multiple male terminals 121 and multiple female terminals 221 can meet the electrical connection requirements of multiple wires, increasing the applicability of connector 100. The latch is provided on the two first sidewalls 15 and two second sidewalls 25 arranged opposite each other along the second direction. This ensures that the latch will not affect the insertion operation of male terminals 121 and female terminals 221 along the first direction, and facilitates the snap-fit ​​connection between the connector cover 3 and the plug shell 11 and the socket shell 21.

[0085] For example, the second direction can be orthogonal to the first direction.

[0086] Reference Figure 9 , Figure 13 , Figure 14 and Figure 15 According to some embodiments of the present invention, the plug housing 11 includes two first sidewalls 15 disposed opposite to each other along a second direction and a third sidewall 15 disposed along a third direction (e.g., refer to...). Figure 1 The socket housing 21 includes two third sidewalls 16 arranged opposite each other in the e3 direction. It also includes a second sidewall 25 arranged opposite each other in the second direction and a fourth sidewall 26 arranged opposite each other in the third direction. A latch is provided on the first sidewall 15 and the second sidewall 25. The third direction, the second direction, and the first direction intersect each other. The latch is located on the two first sidewalls 15 and the two second sidewalls 25 arranged opposite each other in the second direction. This ensures that the latch does not affect the insertion operation of the male terminal 121 and the female terminal 221 in the first direction. It also makes full use of the space in the plug housing 11 and the socket housing 21 in the second direction, facilitating the latching connection between the connecting cover 3 and the plug housing 11 and the socket housing 21. Furthermore, it reduces the external space occupied by the plug housing 11 and the socket housing 21 in the third direction, resulting in a smaller size of the connector 100 in the third direction.

[0087] For example, the third direction, the second direction, and the first direction can be orthogonal to each other.

[0088] Reference Figure 9 , Figure 13 , Figure 14 and Figure 15According to some embodiments of this utility model, the connecting cover 3 includes a cover body 34 and a side plate. The side plate is connected to the outer edge of the cover body 34 and is located on one side of the cover body 34 along a third direction. The cover body 34 covers the third side wall 16 and the fourth side wall 26, and the side plate is provided with a locking hole 331. By covering the third side wall 16 and the fourth side wall 26 with the cover plate located on one side of the cover body 34 along a third direction, it can better cover the outer periphery of the socket shell 21 and the plug shell 11, realize the connection between the male plug 1 and the female socket 2, and provide a certain degree of protection for the male plug 1 and the female socket 2.

[0089] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 According to some embodiments of the present invention, there are two connecting covers 3, which are arranged along a third direction. The plug shell 11 and the socket shell 21 have a first side 43 and a second side 44 arranged opposite to each other along a third direction. The cover body 34 of one connecting cover 3 covers the third side wall 16 and the fourth side wall 26 located on the first side 43, and the cover body 34 of the other connecting cover 3 covers the third side wall 16 and the fourth side wall 26 located on the second side 44. A portion of the buckles provided on the first side wall 15 and the second side wall 25 engage with the buckle hole 331 on one of the connecting covers 3, and another portion of the buckles provided on the first side wall 15 and the second side wall 25 engage with the buckle hole 331 on the other connecting cover 3.

[0090] One of the connecting covers 34 covers the third side wall 16 of the plug shell 11 and the fourth side wall 26 of the socket shell 21 located on the first side 43. A portion of the snap fasteners on the first side wall 15 and the second side wall 25 engage with the snap hole 331 on one of the connecting covers 3, enabling a snap-fit ​​connection between one of the connecting covers 3 and the socket shell 21 and the plug shell 11. Similarly, the other connecting cover 3 covers 34 on the third side wall 16 of the plug shell 11 and the fourth side wall 26 of the socket shell 21 located on the second side 44. Another portion of the snap fasteners on the first side wall 15 and the second side wall 25 engage with the snap hole 331 on the other connecting cover 3, enabling a snap-fit ​​connection between the other connecting cover 3 and the socket shell 21 and the plug shell 11. This process achieves a snap-fit ​​connection between both connecting covers 3 and the socket shell 21 and the plug shell 11.

[0091] Reference Figure 1 , Figure 5 and Figure 6According to some embodiments of this utility model, multiple latches located on the same side in the second direction include a first latch 41 and a second latch 42. The first sidewall 15 and the second sidewall 25 are both provided with the first latch 41 and the second latch 42. A latching hole 331 on one connecting cover 3 engages with the first latch 41, and a latching hole 331 on the other connecting cover 3 engages with the second latch 42. The latching hole 331 on one connecting cover 3 engages with the first latch 41 on the first sidewall 15 of the plug housing 11 and the second sidewall 25 of the socket housing 21, enabling one connecting cover 3 to be latched and connected to both the socket housing 21 and the plug housing 11. Similarly, the latching hole 331 on the other connecting cover 3 engages with the second latch 42 on the first sidewall 15 of the plug housing 11 and the second sidewall 25 of the socket housing 21, enabling the other connecting cover 3 to be latched and connected to both the socket housing 21 and the plug housing 11, thus achieving a complete connection between the two connecting covers 3 and the socket housing 21 and the plug housing 11.

[0092] Reference Figures 9-11 According to some embodiments of the present invention, the first buckle 41 has a first buckle surface 411, which abuts against the inner wall of the corresponding buckle hole 331 in a third-party upward direction. The second buckle 42 has a second buckle surface 421, which abuts against the inner wall of the corresponding buckle hole 331 in a third-party upward direction. The first buckle surface 411 and the second buckle surface 421 have opposite orientations. Since the two connecting covers 3 are arranged along the third direction, the first latching surface 411 of the first latch 41 abuts against the inner wall of the corresponding latch hole 331 in the third direction, which can limit the assembly between the first latch 41 and the corresponding latch hole 331, so that the first latch 41 is more stably kept in the corresponding latch hole 331, thereby reducing the possibility of one of the connecting covers 3 and the socket shell 21 and the plug shell 11 moving relative to each other in the third direction and toward the direction close to the second latching surface 421; and the second latching surface 421 abuts against the inner wall of the corresponding latch hole 331 in the third direction, which can limit the assembly between the second latch 42 and the corresponding latch hole 331, so that the second latch 42 is more stably kept in the corresponding latch hole 331, thereby reducing the possibility of the other connecting cover 3 and the socket shell 21 and the plug shell 11 moving relative to each other in the third direction and toward the direction close to the first latching surface 411.

[0093] Reference Figure 14 and Figure 15According to some embodiments of this utility model, each connecting cover 3 has a plurality of clearance notches 36 arranged at intervals along a first direction on its side plate. A connecting lug 35 is defined between two adjacent clearance notches 36 on the same side plate. The connecting lug 35 is provided with a locking hole 331. One of the connecting lugs 35 of the two connecting covers 3 is accommodated in the clearance notch 36 of the other connecting cover 3. The clearance notch 36 facilitates the accommodation of the connecting lug 35, making the assembly of the two connecting covers 3 more convenient. The clearance notch 36 also serves as a limit for the assembly between the two connecting covers 3, ensuring accurate assembly position between the two connecting covers 3. By arranging the plurality of clearance notches 36 at intervals along the first direction, and correspondingly, arranging the plurality of connecting lugs 35 at intervals along the first direction, the relative movement of the two connecting covers 3 along the first direction can be prevented, which is beneficial to improving the overall stability of the connector 100.

[0094] For example, the assembly process of the plug housing 11 and the socket housing 21 with the two connecting covers 3 can be as follows: First, insert the male terminal 121 and the female terminal 221 along the first direction, so that the first end face 111 of the plug housing 11 fits against the second end face 211 of the socket housing 21. Then, place the plug housing 11 and the socket housing 21 into the receiving groove 31 of one of the connecting covers 3, and make the first snapping surface 411 of the first buckle 41 abut against the inner wall of the corresponding snap hole 331 in the third direction. Then, assemble the other connecting cover 3 onto the plug housing 11 and the socket housing 21. On one of the connecting covers 3, the plug housing 11 and the socket housing 21 are placed into the receiving groove 31 of the other connecting cover 3, and the second snapping surface 421 of the second buckle 42 abuts against the inner wall of the corresponding snap hole 331 in the third direction, so that the connecting lug 35 of one of the connecting covers 3 is accommodated in the clearance notch 36 of the other connecting cover 3, and the connecting lug 35 of the other connecting cover 3 is accommodated in the clearance notch 36 of one of the connecting covers 3, thus completing the assembly process of the plug housing 11 and the socket housing 21 with the two connecting covers 3.

[0095] Reference Figure 1 , Figure 14 and Figure 15According to some embodiments of this utility model, the male plug 1 includes a male wire 13 connected to a male terminal 121; the female socket 2 includes a female wire 23 connected to a female terminal 221; the side plate includes a first side plate 32 and a second side plate 33; the first side plate 32 is located on opposite sides of the cover 34 along a first direction; the second side plate 33 is located on opposite sides of the cover 34 along a second direction; and a locking hole 331 is formed on the second side plate 33. A first wire-passing notch 321 is formed on the first side plate 32 on one side of the body 34 along the second direction, and a second wire-passing notch 322 is formed on the first side plate 32 on the other side of the cover 34 along the second direction. The first wire-passing notches 321 of the two connecting covers 3 are joined to form a first wire-passing hole 323, through which the male wire 13 passes. The second wire-passing notches 322 of the two connecting covers 3 are joined to form a second wire-passing hole 324, through which the female wire 23 passes.

[0096] Since the cover 34 covers the third sidewall 16 and the fourth sidewall 26 on opposite sides along the third direction, and the first side plate 32 is located on opposite sides of the cover 34 along the first direction, and the second side plate 33 is located on opposite sides of the cover 34 along the second direction, the first side plate 32, the second side plate 33 and the cover 34 can better cover the outer periphery of the socket shell 21 and the plug shell 11, so that the connecting cover 3 plays a protective and support role for the socket shell 21 and the plug shell 11. By forming a first wire-passing notch 321 on the first side plate 32 of the cover 34 along one side of the second direction, and a second wire-passing notch 322 on the first side plate 32 of the cover 34 along the other side of the second direction, a first wire-passing hole 323 can be formed on one side of the connecting cover 3 along the second direction to facilitate the passage of the male wire 13, and a second wire-passing hole 324 can be formed on the other side of the connecting cover 3 along the second direction to facilitate the passage of the female wire 23, thereby making the overall structure of the male plug 1, the female socket 2 and the connecting cover 3 more compact.

[0097] In addition, the first wire through hole 323 and the second wire through hole 324 can limit the male wire 13 and the female wire 23, reducing the possibility of the male wire 13 or the female wire 23 swinging significantly, thereby reducing the possibility of the male wire 13 causing the male terminal 121 or the female wire 23 causing the female terminal 221 to tilt or swing, and thus reducing the friction and wear of the contact point between the male terminal 121 and the female terminal 221 caused by the tilting or swinging of the male terminal 121 or the female terminal 221.

[0098] Reference Figure 2 , Figure 4 and Figure 8According to some embodiments of the present invention, the inner peripheral wall of the plug housing 11 is provided with a first limiting protrusion 17, and the male terminal 121 is provided with a first limiting spring piece 1211. The first limiting spring piece 1211 is located inside the plug housing 11 and extends obliquely toward the inner peripheral wall of the plug housing 11 in the direction from the female terminal socket 2 to the male terminal plug 1. In the first direction, the first limiting protrusion 17 is located on the side of the first limiting spring piece 1211 away from the female terminal socket 2 and the first limiting protrusion 17 abuts against the first limiting spring piece 1211. The first limiting boss 17 abuts against the first limiting spring 1211, which can make the connection between the plug shell 11 and the male terminal 121 simple and have strong stability. The first limiting boss 17 can limit the assembly between the male terminal 121 and the plug shell 11, which can enhance the connection stability between the male terminal 121 and the plug shell 11 and reduce or avoid the possibility of relative movement between the male terminal 121 and the plug shell 11 along the first direction.

[0099] For example, the assembly process between the male terminal 121 and the plug housing 11 can be as follows: the plug housing 11 and the male terminal 121 are inserted into each other along the first direction, and the first limiting spring 1211 undergoes elastic deformation along the third direction. This allows the male terminal 121 to be inserted into the plug housing 11 more smoothly. After the male terminal 121 is inserted into the plug housing 11, the first limiting spring 1211 returns to its original shape along the third direction due to its own elastic restoring force. At this time, it is convenient for the side of the first limiting spring 1211 away from the female socket 2 to abut against the first limiting boss 17, thereby enhancing the connection stability between the male terminal 121 and the plug housing 11.

[0100] Reference Figure 2 , Figure 4 and Figure 8 According to some embodiments of this utility model, the first limiting protrusion 17 includes two oppositely arranged along a third direction, and the first limiting spring piece 1211 includes two oppositely arranged along a third direction. The two first limiting spring pieces 1211 abut against the two first limiting protrusions 17 respectively. The abutting connection between the two first limiting protrusions 17 and the two first limiting spring pieces 1211 arranged oppositely along a third direction can further enhance the connection stability between the male terminal 121 and the plug housing 11, and reduce or avoid the possibility of relative movement between the male terminal 121 and the plug housing 11 along the first direction.

[0101] Reference Figure 2 , Figure 3 and Figure 12According to some embodiments of this utility model, the inner peripheral wall of the socket housing 21 is provided with a second limiting boss 27, and the female terminal 221 is provided with a second limiting spring piece 2211. The second limiting spring piece 2211 is located inside the socket housing 21 and extends obliquely towards the inner peripheral wall of the socket housing 21 in the direction from the male plug 1 to the female socket 2. In the first direction, the second limiting boss 27 is located on the side of the second limiting spring piece 2211 away from the male plug 1 and abuts against the second limiting spring piece 2211. The abutting connection between the second limiting boss 27 and the second limiting spring piece 2211 can simplify the connection between the socket housing 21 and the female terminal 221 and provide strong stability. The second limiting boss 27 can limit the assembly between the female terminal 221 and the socket housing 21, which can enhance the connection stability between the female terminal 221 and the socket housing 21 and reduce or avoid the possibility of relative movement between the female terminal 221 and the socket housing 21 in the first direction.

[0102] For example, the assembly process between the female terminal 221 and the socket housing 21 can be as follows: the socket housing 21 and the female terminal 221 are inserted into each other along the first direction, and the second limiting spring 2211 undergoes elastic deformation along the third direction. This allows the female terminal 221 to be inserted into the socket housing 21 more smoothly. After the female terminal 221 is inserted into the socket housing 21, the second limiting spring 2211 returns to its original shape along the third direction due to its own elastic restoring force. At this time, it is convenient for the side of the second limiting spring 2211 away from the female terminal socket 2 to abut against the second limiting boss 27, thereby enhancing the connection stability between the female terminal 221 and the socket housing 21.

[0103] Reference Figure 2 , Figure 3 and Figure 12 According to some embodiments of this utility model, the second limiting boss 27 includes two oppositely arranged along a third direction, and the second limiting spring piece 2211 includes two oppositely arranged along a third direction. The two second limiting spring pieces 2211 abut against the two second limiting bosses 27 respectively. The abutting connection between the two second limiting bosses 27 and the two second limiting spring pieces 2211 arranged oppositely along a third direction can further enhance the connection stability between the female terminal 221 and the socket housing 21, and reduce or avoid the possibility of relative movement between the female terminal 221 and the socket housing 21 along the first direction.

[0104] Reference Figure 8 According to some embodiments of the present invention, the male terminal 121 is further provided with a first cable routing buckle 18. The first cable routing buckle 18 is located inside the plug housing 11 and faces the side close to the first outlet 14 in the first direction. The first cable routing buckle 18 can fix and support the male terminal wire 13.

[0105] Reference Figure 13According to some embodiments of the present invention, the female terminal 221 is further provided with a second wiring buckle 28. The second wiring buckle 28 is located inside the socket housing 21 and faces the side closer to the second outlet in the first direction. The second wiring buckle 28 can fix and support the female terminal wire 23.

[0106] Reference Figure 1 The vehicle according to the second aspect of the present invention includes the connector 100 according to the first aspect of the present invention described above.

[0107] According to the vehicle of this utility model embodiment, by providing the above-mentioned connector 100, and by having a connecting cover 3 located outside the plug shell 11 and the socket shell 21 and detachably connected to at least one of the plug shell 11 and the socket shell 21, the connecting cover 3 can provide a certain degree of support and protection for the plug shell 11 and the socket shell 21. Furthermore, this can enhance the connection stability between the plug shell 11 and the socket shell 21, and at least a portion of the connecting cover 3 can cover the mating gap between the plug shell 11 and the socket shell 21, thereby reducing the possibility of dust, water, etc. entering the contact interface between the male terminal 121 assembly 12 and the female terminal 221 assembly 22 through the mating gap between the plug shell 11 and the socket shell 21, leading to poor contact or short circuit. This is beneficial to enhancing the overall reliability of the connector 100, thereby enhancing the overall reliability of the vehicle.
