[0025] The connector assembly 100 according to the first aspect of the present application is described below with reference to the accompanying drawings.

[0026] As shown in Figure 1 and Figure 2 The connector assembly 100 according to the first aspect of the present application comprises a circuit board 1, a plug-in part 2 and an anti-disengagement structure 3. One end of the plug-in part 2 is plugged into the circuit board 1. The plug-in part 2 and the circuit board 1 are arranged along a first direction e1. The anti-disengagement structure 3 comprises a plurality of limiting structures 30 arranged along the circumference of the plug-in part 2. The limiting structure 30 comprises an elastic connecting arm 31 provided on the circuit board 1. The free end of the elastic connecting arm 31 is provided with a limiting protrusion 32. The limiting protrusion 32 is located on the side of the plug-in part 2 away from the circuit board 1. At least part of the limiting protrusion 32 is arranged opposite to the plug-in part 2 along the first direction e1.

[0027] That is, the anti-disengagement structure 3 is fixed on the circuit board 1. During the process of plugging the plug-in part 2 into the circuit board 1, that is, during the process of the plug-in part 2 approaching the circuit board 1 along the first direction e1, after the plug-in part 2 contacts the limiting protrusion 32, the plug-in part 2 can drive the elastic connecting arm 31 to elastically deform by pushing the limiting protrusion 32, so that the free end of the elastic connecting arm 31 moves away from the plug-in part 2, so that the plug-in part 2 can smoothly pass through the space between the plurality of limiting protrusions 32, and move to the side of the limiting protrusion 32 on the circuit board 1 along the first direction e1, and complete the alignment and plugging with the circuit board 1. After the plug-in part 2 and the limiting protrusion 32 are disengaged, the pushing force of the plug-in part 2 acting on the limiting protrusion 32 disappears, and the elastic connecting arm 31 restores the elastic deformation and automatically rebounds to the initial position. The initial position here refers to the position of the elastic connecting arm 31 under the action of other forces. The limiting protrusion 32 is moved to the side of the plug-in part 2 away from the circuit board 1 along the first direction e1. At this time, at least part of the limiting protrusion 32 is arranged opposite to the plug-in part 2 along the first direction e1, so that the limiting protrusion 32 can better limit the movement of the plug-in part 2 away from the circuit board 1, to prevent the plug-in part 2 from disengaging from the circuit board 1. In addition, the limiting structure 30 is provided with a plurality of limiting structures arranged along the circumference of the plug-in part 2, which can improve the fixing effect of the anti-disengagement structure 3 on the plug-in part 2, and improve the reliability of the connection between the plug-in part 2 and the circuit board 1.

[0028] In addition, by arranging the anti-disengagement structure 3, the anti-disengagement structure 3 can be flexibly applied to connector structures of various specifications, such as a connector structure without a locking structure between the plug-in part 2 and the circuit board 1, a connector with a one-stage locking structure between the plug-in part 2 and the circuit board 1, and a connector with a multi-stage locking structure between the plug-in part 2 and the circuit board 1, and the application range is wide. It should be noted that the connector structure here is a conventional wire harness connection structure including a male end and a female end in plug-in connection, and the plug-in part 2 can be the male end or the female end, which is not specifically limited here.

[0029] According to the connector assembly 100 of the first aspect of the present application, the limiting protrusion 32 can better limit the movement of the plug-in part 2 in the direction away from the circuit board 1, so as to prevent the plug-in part 2 from being disconnected from the circuit board 1. In addition, the limiting structure 30 is arranged in multiple along the circumferential direction of the plug-in part 2, which can improve the fixing effect of the anti-disengagement structure 3 on the plug-in part 2, so as to improve the reliability of the connection between the plug-in part 2 and the circuit board 1. In addition, the anti-disengagement structure 3 can be flexibly applied to connector structures of various specifications, and the application range is wide.

[0030] According to some embodiments of the present application, the circuit board 1 is provided with a plug-in end 4, and the plug-in part 2 is plugged into the plug-in end 4. That is, the plug-in part 2 is fixed on the circuit board 1 through plug-in connection with the plug-in end 4. The plug-in part 2 can be the male end in the connector structure, and the plug-in end 4 can be the female end in the connector structure, which is not specifically limited here.

[0031] According to some embodiments of the present application, the side of the limiting protrusion 32 away from the plug-in part 2 in the first direction e1 is formed as a guide surface 321, and the guide surface 321 extends obliquely towards the elastic connecting arm 31 in the direction from the plug-in part 2 to the limiting protrusion 32. That is, in the direction of the plug-in part 2 inserted into the circuit board 1, the guide surface 321 is formed as an inclined surface inclined towards the circuit board 1. Therefore, after the plug-in part 2 contacts the guide surface 321, the plug-in part 2 can be guided by the guide surface 321 to correct the positional deviation of the plug-in part 2 relative to the plug-in position on the circuit board 1 in the reference surface direction, wherein the reference surface is perpendicular to the first direction e1, so that the plug-in part 2 can be relatively arranged with the plug-in position on the circuit board 1 along the first direction e1, and the plug-in part 2 can be smoothly butted with the plug-in position on the circuit board 1. In addition, the obliquely arranged guide surface 321 can convert part of the thrust of the plug-in part 2 acting on the guide surface 321 into a thrust for pushing the limiting protrusion 32 to move in the reference surface direction away from the plug-in part 2, so as to reduce the resistance of the limiting protrusion 32 to the plug-in part 2, and to reduce the difficulty of the plug-in part 2 passing through the limiting protrusion 32.

[0032] According to some embodiments of the present application, the side of the limiting protrusion 32 in the first direction e1 towards the plug-in part 2 is a limiting surface 322, and the limiting surface 322 is arranged in the first direction e1 away from the plug-in part 2. That is, after the plug-in part 2 is connected with the plug-in end 4, the limiting protrusion 32 is arranged away from the plug-in part 2. Thus, it is ensured that the plug-in part 2 can pass through the limiting protrusion 32 completely, so as to avoid that the plug-in part 2 blocks the reset of the elastic connecting arm 31, thereby ensuring that the limiting protrusion 32 can move to the side of the plug-in part 2 away from the circuit board 1 after the reset of the elastic connecting arm 31, so as to ensure the limiting effect of the limiting structure 30 on the plug-in part 2. In addition, the space between the limiting surface 322 and the plug-in part 2 can provide space for the machining tolerance of the plug-in part 2, the plug-in end 4, the circuit board 1 and the limiting structure 30, so as to prevent the plug-in part 2 from not passing through the limiting protrusion 32 due to the machining tolerance.

[0033] In one specific example, the side of the plug-in part 2 in the first direction e1 towards the limiting protrusion 32 is a limiting matching surface 21, and the limiting matching surface 21 and the limiting surface 322 are both planes perpendicular to the first direction e1. It can be understood that, since the limiting surface 322 and the limiting matching surface 21 are both planes perpendicular to the first direction e1, when the limiting surface 322 contacts the limiting matching surface 21, the plug-in part 2 only exerts a pushing force on the limiting protrusion 32 in the first direction e1, thereby avoiding the sliding of the limiting surface 322 relative to the limiting matching surface 21 towards the outer circumferential side of the plug-in part 2, which causes the limiting failure of the limiting structure 30, so as to ensure the limiting effect of the limiting structure 30 on the plug-in part 2.

[0034] According to some embodiments of the present application, the distance range of the limiting surface 322 and the plug-in part 2 in the first direction e1 is 0.2mm-0.6mm. It can be understood that, in the first direction e1, the smaller the distance between the limiting surface 322 and the plug-in part 2, the better the limiting effect of the limiting surface 322 on the movement of the plug-in part 2 towards the direction away from the circuit board 1, but the higher the risk of interference that the contact between the limiting protrusion 32 and the plug-in part 2 causes the elastic connecting arm 31 to fail to rebound smoothly; on the contrary, the larger the distance between the limiting surface 322 and the plug-in part 2, the worse the limiting effect of the limiting surface 322 on the movement of the plug-in part 2 towards the direction away from the circuit board 1, but the lower the risk of interference that the contact between the limiting protrusion 32 and the plug-in part 2 causes the elastic connecting arm 31 to fail to rebound smoothly. Therefore, by setting the distance range of the limiting surface 322 and the plug-in part 2 in the first direction e1 to be within the range of 0.2mm to 0.6mm, the limiting effect of the limiting surface 322 on the movement of the plug-in part 2 towards the direction away from the circuit board 1 can be ensured, and the risk of interference that the contact between the limiting protrusion 32 and the plug-in part 2 causes the elastic connecting arm 31 to fail to rebound smoothly can be reduced.

[0035] The distance between the limiting surface 322 and the plug-in part 2 in the first direction e1 can be 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, etc., which is not specifically limited here.

[0036] According to some embodiments of the present application, the plurality of limiting structures 30 at least includes two distributed on opposite sides of the plug-in part 2. Therefore, by the two limiting structures 30 distributed on opposite sides of the plug-in part 2, the parts on opposite sides of the plug-in part 2 can be limited respectively, which can prevent the plug-in part 2 from being separated due to insufficient single-side limiting strength, so as to improve the limiting effect of the anti-separation structure 3 on the plug-in part 2.

[0037] According to some embodiments of the present application, the size of the plug-in part 2 in the second direction e2 is smaller than the size of the plug-in part 2 in the third direction e3, and the limiting structure 30 is distributed on the opposite sides of the plug-in part 2 in the third direction e3. The second direction e2 is perpendicular to the first direction e1, and the third direction e3 is perpendicular to the second direction e2 and the first direction e1. That is, the two limiting structures 30 are respectively used to limit the two ends of the plug-in part 2 in the length direction. Compared with setting the limiting structure 30 on the two sides in the width direction, setting the two limiting structures 30 on the two ends of the plug-in part 2 in the length direction can save the number of limiting structures 30 while ensuring the limiting effect on the plug-in part 2, so as to reduce the cost of the anti-separation structure 3.

[0038] According to some embodiments of the present application, the plug-in part 2 is formed with a locking structure 22 connected with the circuit board 1, the locking structure 22 is located on one side of the plug-in part 2 in the second direction e2, and the at least two limiting structures 30 are distributed on the opposite sides of the plug-in part 2 in the third direction e3. That is, through the fixed connection of the locking structure 22, the movement of the plug-in part 2 in the direction away from the circuit board 1 on one side in the second direction e2 can be limited, and through the two limiting structures 30 located on the opposite sides of the plug-in part 2 in the third direction e3, the movement of the plug-in part 2 in the direction away from the circuit board 1 on the two sides in the third direction e3 can be limited. Therefore, through the anti-separation structure 3, the part of the plug-in part 2 outside the locking area of the locking structure 22 can be limited, so as to improve the comprehensiveness of the limiting, thereby improving the limiting effect of the anti-separation structure 3 on the plug-in part 2.

[0039] In a specific example, the locking structure 22 on the plug-in part 2 is a clamping structure connected with the plug-in end 4, that is, the plug-in end 4 and the plug-in part 2 are clamped and connected to realize primary locking, and the limiting of the plug-in part 2 by the anti-separation structure 3 can realize secondary locking, so as to ensure the stable connection of the plug-in end 4 and the plug-in part 2.

That is, the first connecting arm 311 and the second connecting arm 312 jointly form the elastic connecting arm 31 in the shape of "L", which can effectively extend the length of the second connecting arm 312, reduce the stress requirement of the deformation of the second connecting arm 312 relative to the first connecting arm 311, and thus reduce the resistance of the limiting structure 30 to the insertion of the connector 2.

[0041] According to some embodiments of the utility model, the connector assembly 100 further includes a fixed frame 5 arranged on the circuit board 1, the fixed frame 5 is located on the outer peripheral side of the connector, and the limiting structure 30 is integrally formed with the fixed frame 5. Among them, the fixed frame 5 can be other components distributed around the connector, by integrally forming the limiting structure 30 with the fixed frame 5, the process of separately arranging the mounting structure for the limiting structure 30 is saved, not only the structure and performance stability of the limiting structure 30 and the fixed frame 5 can be ensured, but also the molding is convenient, the manufacturing is simple, the connecting parts and the connecting process used between the limiting structure 30 and the fixed frame 5 are saved, the production cost is low, the assembly efficiency of the limiting structure 30 and the fixed frame 5 is greatly improved, the connection reliability of the limiting structure 30 and the fixed frame 5 is ensured, and the overall strength and stability of the integrally formed structure is higher and the service life is longer.
