Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a connector assembly. Background Technology

[0002] In modern electronic devices and power systems, connector design is crucial for ensuring reliable electrical connections and signal transmission. Connector mating typically employs assist mechanisms to ensure a smooth and secure connection between the male and female connectors.

[0003] Currently, assist mechanisms sometimes use knobs to help connectors connect and mate. However, current knobs have some significant shortcomings. For example, current knobs generally cannot ensure a secure connection between the male and female connectors in the correct position, easily leading to loosening or disengagement of the connection, ultimately affecting the stability and reliability of the electrical connection between the male and female connectors. Furthermore, current knobs make it difficult for users to determine whether the correct locking position has been reached when rotating the knob, resulting in operational uncertainty, requiring multiple adjustments, increasing operational complexity, and leading to a poor user experience. Utility Model Content

[0004] This application provides a connector assembly that solves the problems of unstable connection and operational uncertainty caused by the lack of a pre-locking structure in current knobs, resulting in a poor user experience.

[0005] To achieve the above objectives, this application also provides a connector assembly, comprising: a first connector having a first mating end and a first non-mating end in a first direction; a second connector having a second mating end and a second non-mating end in the first direction, the second mating end being inserted into the first mating end along the first direction, the second connector having a helical track with the axis of the helical track parallel to the first direction; and a connecting knob having a first connecting end and a second connecting end in the first direction, the first connecting end being rotatably connected to the first connector, the connecting knob having a guide boss at the second connecting end, the guide boss being configured to slide along the helical track to drive the connecting knob to rotate so as to move the first connector toward or away from the second connector along the first direction; wherein, the first connector has a pre-locking hole at the first mating end, the connecting knob has a pre-locking buckle at the second connecting end, the pre-locking buckle being configured to engage in the pre-locking hole to pre-lock the connecting knob and the first connector.

[0006] The first connector of this application has a pre-locking hole at the first mating end, and the connecting knob has a pre-locking buckle at the second connecting end. The pre-locking buckle is configured to engage with the pre-locking hole to pre-lock the connecting knob and the first connector. The pre-locking of the connecting knob and the first connector is achieved through the cooperation of the pre-locking buckle and the pre-locking hole, preventing the connecting knob from rotating. This allows for the positioning of the guide boss on the connecting knob, facilitating precise alignment of the guide boss on the connecting knob and the spiral track on the second connector. This reduces the uncertainty of user operation, reduces the complexity of the connection operation of the connecting knob and the second connector, improves the user experience, and effectively ensures the connection stability of the connecting knob and the second connector, thereby improving the stability and reliability of the electrical connection between the first connector and the second connector.

[0045] Please see Figures 3-8 , Figure 9The connecting knob 3 has a first connecting end 301 and a second connecting end 302 in the first direction A. The first connecting end 301 is rotatably connected to the first connector 1.

[0046] Please see Figure 9 , Figure 12 , Figures 14-15 The first connector 1 is further provided with an annular groove 114, the axis of which is parallel to the first direction A. Specifically, the annular groove 114 is disposed on the outer wall of the first housing 11. The connecting knob 3 is provided with a rotating latch 31 at the first connecting end 301. The rotating latch 31 is configured to slide along the annular groove 114 to rotatably connect the connecting knob 3 to the first connector 1. The rotating latch 31 is also configured to cooperate with the annular groove 114 to fix the connecting knob 3 and the first connector 1 in the first direction A. In this embodiment, three rotating latches 31 are evenly provided circumferentially on the inner wall of the first connecting end 301 of the connecting knob 3. The three rotating latches 31 are the first rotating latch 311, the second rotating latch 312, and the third rotating latch 313.

[0047] Please see Figure 9 , Figure 12 , Figures 14-15 The first connector 1 also has position bosses 115, which are disposed within the annular groove 114 and arranged at intervals along the circumference of the annular groove 114. In this embodiment, the first connector 1 has three position bosses 115. The three position bosses 115 are a first position boss 1151, a second position boss 1152, and a third position boss 1153, which are arranged at intervals along the circumference of the annular groove 114.

[0048] Please see Figure 14 and Figure 15 When the connecting knob 3 is rotated, at least one rotating latch 31 is configured to slide along the annular groove 114 past the position boss 115. In this embodiment, the first rotating latch 311 is configured to slide along the annular groove 114 past the position boss 115, thereby providing a click feel on the rotating device of the connecting knob 3, making it easy for the user to identify the degree of rotation of the connecting knob 3.

[0049] Please see Figure 14 When the guide boss 32 slides to the starting point 2121, at least one position boss 115 is configured as a pre-locking boss and cooperates with the rotary latch 31 to pre-lock the connecting knob 3 with the first connector 1. Specifically, when the guide boss 32 slides to the starting point 2121 of the spiral track 212, the first position boss 1151 is configured as a pre-locking boss and cooperates with the first rotary latch 311 to pre-lock the connecting knob 3 with the first connector 1.

[0050] Please see Figure 15 When the guide boss 32 slides to the end point 2122, at least one position boss 115 is configured as a final locking boss and cooperates with the rotary latch 31 to final lock the connecting knob 3 to the first connector 1. Specifically, when the guide boss 32 slides to the end point 2122 of the spiral track 212, the third position boss 1153 is configured as a final locking boss and cooperates with the first rotary latch 311 to final lock the connecting knob 3 to the first connector 1.

[0051] Please see Figure 13 The connecting knob 3 has a guide boss 32 on the second connecting end 302. The guide boss 32 is configured to slide along the spiral track 212 to drive the connecting knob 3 to rotate, thereby causing the first connector 1 to move towards or away from the second connector 2 in the first direction A. In this embodiment, the connecting knob 3 has two guide bosses 32 on the inner wall of the second connecting end 302, and the two guide bosses 32 slide along the two spiral tracks 212 respectively. By the cooperation of the guide bosses 32 of the connecting knob 3 and the spiral tracks 212 of the second connector 2, the first connector 1 is driven towards or away from the second connector 2 in the first direction A, thereby facilitating the mating and disassembly of the first connector 1 and the second connector 2, making the mating and disassembly of the first connector 1 and the second connector 2 easy and effortless, and providing a better working experience. The connecting knob 3 can also improve the holding force between the first connector 1 and the second connector 2, and improve the reliability of the connection between them.

[0052] Please see Figure 13 The outer wall of the connecting knob 3 is provided with an operating rib 35. The operating rib 35 can improve the user's operating experience.

[0053] Please see Figure 13 , Figures 16-17 The first connector 1 has a pre-locking hole 116 at its first mating end 101, and the connecting knob 3 has a pre-locking buckle 33 at its second connecting end 302. The pre-locking buckle 33 is configured to engage within the pre-locking hole 116 to pre-lock the connecting knob 3 and the first connector 1. The pre-locking of the connecting knob 3 and the first connector 1 is achieved through the cooperation of the pre-locking buckle 33 and the pre-locking hole 116, preventing the connecting knob 3 from rotating. This allows for the positioning of the guide boss 32 on the connecting knob 3, facilitating precise alignment of the guide boss 32 on the connecting knob 3 and the spiral track 212 on the second connector 2. This reduces the uncertainty of user operation, simplifies the connection operation of the connecting knob 3 and the second connector 2, improves the user experience, and effectively ensures the connection stability of the connecting knob 3 and the second connector 2, thereby enhancing the stability and reliability of the electrical connection between the first connector 1 and the second connector 2.

[0054] Please see Figure 11 , Figure 13 , Figures 16-17 The second connector 2 has an unlocking rib 213 on the second mating end 201. When the first mating end 101 and the second mating end 201 are inserted and engaged, the unlocking rib 213 is configured to engage in the pre-locking hole 116 to push the pre-locking buckle 33 out of the pre-locking hole 116. In this embodiment, the pre-locking buckle 33 engages in the pre-locking hole 116 from the upper end, and the unlocking rib 213 engages in the pre-locking hole 116 from the lower end. When the unlocking rib 213 extends into the pre-locking hole 116, it pushes the pre-locking buckle 33 out of the pre-locking hole 116, thereby allowing the connecting knob 3 to rotate relative to the first connector 1. This allows the guide boss 32 to slide along the spiral track 212, ultimately driving the first connector 1 to move towards the second connector 2 along the first direction A, thus achieving the mating of the first connector 1 and the second connector 2.

[0055] Please see Figures 3-4 , Figure 18 The connector assembly also includes a limiting member 4. When the guide boss 32 slides to the end point 2122, the limiting member 4 is configured to lock the connecting knob 3 to the first connector 1. Specifically, the limiting member 4 has a limiting portion 41 at one end near the connecting knob 3, and a limiting mating portion 34 at one end near the limiting member 4. The limiting portion 41 is configured to cooperate with the limiting mating portion 34 to lock the connecting knob 3 to the first connector 1. In this embodiment, the limiting portion 41 is a limiting protrusion, and the limiting mating portion 34 is a limiting groove. The cooperation between the limiting portion 41 and the limiting mating portion 34 locks the connecting knob 3 to the first connector 1, preventing the connecting knob 3 from reversing, thereby improving the connection reliability of the first connector 1 and the second connector 2.

[0056] Please see Figure 9 , Figures 18-19 The limiting member 4 is slidably connected to the first connector 1 along the first direction A. The first connector 1 is also provided with a guide portion 117, which extends along the first direction A. The limiting member 4 is provided with a guide mating portion 42 that cooperates with the guide portion 117. In this embodiment, the guide portion 117 is a guide rib, and the guide mating portion 42 is a guide groove.

[0057] Please see Figure 9 , Figures 18-19The first connector 1 is further provided with a primary locking portion 118 and a secondary locking portion 119 arranged at intervals along the first direction A. The secondary locking portion 119 is located on the side of the primary locking portion 118 away from the first non-mating end 102. The limiting member 4 is provided with a locking buckle 43, which engages with the side of the primary locking portion 118 near the secondary locking portion 119 to lock the limiting member 4 to the first connector 1 in the first manner. When the guide boss 32 slides to the end point 2122, the locking buckle 43 engages with the side of the secondary locking portion 119 away from the primary locking portion 118 to lock the limiting member 4 to the first connector 1 in the second manner.

[0058] Please see Figure 9 , Figures 18-19 The first connector 1 is further provided with a snap-fit ​​portion 120, and the limiting member 4 is further provided with a snap-fit ​​mating portion 44 that cooperates with the snap-fit ​​portion 120. In this embodiment, the snap-fit ​​portion 120 is a snap-fit ​​protrusion, and the snap-fit ​​mating portion 44 is a snap-fit ​​groove. The snap-fit ​​portion 120 and the snap-fit ​​mating portion 44 cooperate with each other to prevent the limiting member 4 from rotating relative to the first connector 1.

[0059] Please see Figures 1-19 In this embodiment, both the first connector 1 and the second connector 2 are cylindrical. Compared with the existing cuboid-shaped first connector 1 and second connector 2, they have advantages such as compact structure, smaller outer contour space, and better hand grip operation experience.

[0060] During the assembly of the connecting components of this application, the limiting member 4 is sleeved on the outside of the first housing 11, and the locking buckle 43 cooperates with the primary locking part 118 to lock the limiting member 4 onto the first housing 11. The first sealing member 13 and the cable clamp 14 are sleeved on the first terminal assembly 12, and then the first terminal assembly 12 is inserted into the first housing 11 and fixed to the first housing 11. Then, the rear cover 15 is sleeved on the first terminal assembly 12, and the rear cover limiting hole 151 cooperates with the rear cover limiting protrusion 112 on the first housing 11 to fix the rear cover 15 and the first housing 11. The second sealing member 16 is sleeved on the first mating end 101 of the first housing 11, and then the sealing positioning member 17 is sleeved on the first mating end 101 of the first housing 11. The sealing positioning member 17 and the first housing 11 are fixed by the cooperation of the sealing limiting protrusion 171 and the sealing limiting hole 113 on the first housing 11. The connecting knob 3 is fitted onto the first housing 11. The rotating latch 31 of the connecting knob 3 engages with the annular groove 114 on the first housing 11 to rotatably connect the connecting knob 3 to the first housing 11. A pre-locking hole 116 and a pre-locking latch 33 engage to prevent accidental rotation of the connecting knob 3. An unlocking rib 213 on the second housing 21 extends into the pre-locking hole 116 and pushes up the pre-locking latch 33, allowing the connecting knob 3 to rotate relative to the first connector 1. A guide boss 32 on the connecting knob 3 engages with the spiral track 212 on the second housing 21 to drive the connecting knob 3 to rotate, thereby moving the first connector 1 toward the second connector 2, ultimately achieving the insertion and engagement of the first connector 1 and the second connector 2. When the guide boss 32 rotates to the end point 2122 of the spiral track 212, the first rotating latch 311 and the third position boss 1153 engage to finally lock the connecting knob 3 and the first connector 1 to prevent accidental rotation of the connecting knob 3. When the guide boss 32 rotates to the end point 2122 of the spiral track 212, the limiting member 4 slides along the guide portion 117 on the first housing 11 toward the second connector 2, and the limiting portion 41 cooperates with the limiting engagement portion 34 on the connecting knob 3 to lock the connecting knob 3 and the first connector 1 to prevent the connecting knob 3 from turning accidentally. At the same time, the locking engagement portion 44 on the limiting member 4 cooperates with the locking portion 120 on the first housing 11 to prevent the limiting member 4 from turning accidentally.
