Description

Technical Field

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

[0002] Threaded holes are a common connection structure, widely used in the field of connection and fixation technology. For example, threaded holes in vehicles can be threaded onto the screws of phone holders, allowing the phone to be indirectly fixed to the vehicle. When electrical devices such as phone holders require power, an additional connector connected to a power supply is needed to plug into the connector on the electrical device to supply power.

[0003] However, the operating conditions of vehicles or other terminal equipment with threaded holes are more complex and prone to vibration or impact. The two connectors that rely solely on plugging to achieve electrical connection are prone to loosening, which can lead to poor contact and other connection abnormalities, causing the connectors to be unable to provide power. Utility Model Content

[0004] In view of this, this application provides a connector assembly and a terminal device that can both securely connect electrical equipment and supply power to the electrical equipment.

[0005] In a first aspect, embodiments of this application provide a connector assembly, the connector assembly including a first connector and a second connector;

[0006] The first connector has a slot and a plurality of first wedge teeth. The slot wall is provided with internal threads, and the first wedge teeth are located on the side of the internal threads away from the bottom of the slot and protrude away from the bottom of the slot.

[0007] The second connector has an external thread and a plurality of second wedge-shaped teeth protruding toward the bottom of the slot, the second wedge-shaped teeth being located on the side of the external thread away from the bottom of the slot;

[0008] When the first connector and the second connector are in the plugged-in state, the internal thread and the external thread mesh with each other, and the plurality of first wedge teeth mesh with the plurality of second wedge teeth.

[0009] The connector assembly provided in this application includes a first connector and a second connector. When the first and second connectors are in a plugged-in state, they are not only fixed by the interlocking of the internal thread of the first connector and the external thread of the second connector, but also prevented from loosening by the interlocking of the first wedge teeth of the first connector and the second wedge teeth of the second connector, thus improving the stability of the connection between the two connectors. Furthermore, if the first connector is electrically connected to a power supply device and the second connector is electrically connected to a power user device, and the first and second connectors are in a plugged-in state, the power supply device can supply power to the power user device through the electrically connected first and second connectors. In other words, the connector assembly provided in this application not only provides a stable connection to the power user device but also supplies power to it.

[0010] In some possible implementations, the slope angle of the helical tooth surface of the second wedge tooth is greater than the thread helix angle of the external thread.

[0011] In the technical solution of this application, it can be ensured that when the internal thread and the external thread rotate relative to each other, the first wedge tooth and the second wedge tooth will not rotate relative to each other, so that the first wedge tooth and the second wedge tooth can play the role of preventing loosening.

[0012] In some possible implementations, a stepped hole is formed at the top of the slot, the stepped hole having a first side hole wall, a second side hole wall and a bearing surface connected in sequence, the first side hole wall and the second side hole wall both extending parallel to the insertion and extraction direction, the diameter of the first side hole wall being larger than the inner diameter of the internal thread and smaller than the diameter of the second side hole wall, and the bearing surface intersecting the insertion and extraction direction;

[0013] Multiple first wedge-shaped teeth are located on the bearing surface and are evenly distributed around the first side hole wall at preset intervals;

[0014] When the first connector and the second connector are in the plugging state, the outer surface of the second wedge-shaped tooth abuts against the wall of the second side hole.

[0015] In the technical solution of this application, when the second connector is screwed into the first connector, the second side hole wall can limit the circumferential movement of the second wedge-shaped teeth, thereby preventing the second connector from shifting and ensuring that the second connector can be screwed into place and achieve a stable electrical connection with the first connector.

[0016] In some possible implementations, the first connector includes a first base, a first housing, and a first terminal assembly, the first base having the slot and the plurality of first wedge teeth, the first housing being located within the slot, the first terminal assembly being located within the first housing, and the first housing having a first opening toward the slot opening;

[0017] The contact end of the second connector extends into the first housing through the slot and the first opening, and abuts against the first terminal assembly.

[0018] In the technical solution of this application, the first housing can position the first terminal assembly, and the slot can position the first housing, thereby improving the assembly efficiency of the first connector. The second connector, by inserting into the first opening, can abut against the first terminal assembly to achieve electrical connection with the first connector, thereby also improving the insertion efficiency of the first connector and the second connector.

[0019] In some possible implementations, the second connector includes a second base, a second housing, and a second terminal assembly. The second base has a through hole and the external thread. The second housing extends through the through hole. The second terminal assembly is embedded in the second housing. The solder end of the second terminal assembly protrudes from the top of the second housing, and the contact end of the second terminal assembly protrudes from the second housing.

[0020] When the first connector and the second connector are in the plugged-in state, the portion of the second housing extending out of the through hole is located inside the first housing, and the contact end of the second terminal assembly abuts against the first terminal assembly.

[0021] In the technical solution of this application, the second housing can fix the second terminal assembly. When the contact end of the second terminal assembly abuts against the first terminal assembly, the first connector and the second connector are electrically connected through the first terminal assembly and the second terminal assembly.

[0022] In some possible implementations, the first terminal assembly includes a first crown spring terminal, a second crown spring terminal, and a third crown spring terminal arranged sequentially along the insertion direction. The first crown spring terminal includes a first contact portion and a first welding portion, the second crown spring terminal includes a second contact portion and a second welding portion, and the third crown spring terminal includes a third contact portion and a third welding portion.

[0023] The first contact portion, the second contact portion, and the third contact portion are coaxially arranged and sleeved on the contact end of the second terminal assembly. The first welding portion, the second welding portion, and the third welding portion respectively protrude from the side wall of the second housing and are electrically connected to the corresponding first wire.

[0024] In the technical solution of this application, since the first terminal assembly includes three crown spring terminals, the contact area between the contact ends of the first terminal assembly and the second terminal assembly can be increased. Thus, when the soldered parts of the three crown spring terminals are electrically connected to the corresponding first wires, and the contact parts of the three crown spring terminals abut against the contact ends of the second terminal assembly, the current carrying capacity of the connector assembly can be increased.

[0025] In some possible implementations, the second terminal assembly includes a first terminal, a second terminal, and a third terminal extending in the insertion direction, the second terminal being disposed around the first terminal, and the third terminal being disposed around the second terminal;

[0026] The first terminal includes a fourth contact portion and a fourth solder portion, the second terminal includes a fifth contact portion and a fifth solder portion, and the third terminal includes a sixth contact portion and a sixth solder portion;

[0027] The fourth, fifth, and sixth welding portions are electrically connected to their respective second wires; the fourth contact portion extends through the bottom of the second housing, and the fifth and sixth contact portions extend through the sidewalls of the second housing, with the fifth contact portion located between the fourth and sixth contact portions;

[0028] The fourth contact portion abuts against the inner wall of the third crown spring terminal, the fifth contact portion abuts against the inner wall of the second crown spring terminal, and the sixth contact portion abuts against the inner wall of the first crown spring terminal.

[0029] In the technical solution of this application, the inner wall of the crown spring terminal abuts against the corresponding contact portion, thereby increasing the contact area between the first terminal assembly and the second terminal assembly, thereby increasing the current carrying capacity of the connector assembly. At the same time, since the crown spring terminal is elastic, it can also provide inward pressure to the corresponding contact portion, thereby enabling the first connector and the second connector to maintain a stable electrical connection.

[0030] In some possible implementations, the diameter of the first terminal gradually increases in the direction from the fourth welding portion to the fourth contact portion.

[0031] In the technical solution of this application, the first terminal with a gradually increasing diameter can improve the bending resistance of the second connector, thereby improving the strength and reliability of the second connector.

[0032] In some possible implementations, any one of the first terminal, the second terminal, and the third terminal is a detection terminal, and the first crown spring terminal, the second crown spring terminal, and the third crown spring terminal corresponding to the detection terminal is the target terminal;

[0033] The detection terminal is used to send a current conduction signal when it comes into contact with the target terminal.

[0034] In the technical solution of this application, it is possible to determine that the second terminal has been electrically connected to the corresponding crown spring terminal based on the current conduction signal emitted by the detection terminal. This avoids the situation where the terminal is not properly inserted and is misaligned with the crown spring terminal, thereby ensuring that the first connector and the second connector are properly inserted and improving the reliability of the connector assembly.

[0035] In some possible implementations, the first connector further includes a third housing;

[0036] The first base has a second opening on its side wall. The first housing extends into the slot through the second opening. The third housing is engaged with the side of the first housing facing the first opening and is connected to the first base. A wiring hole communicating with the inside of the first housing is formed between the third housing and the first housing. The wiring hole is used to accommodate the corresponding first wire.

[0037] In the technical solution of this application, the first terminal assembly can be assembled with the first housing first, and then the first housing can be inserted into the slot through the second opening, which can improve the assembly efficiency of the first connector. Furthermore, the wiring hole formed by the first housing and the third housing facilitates the positioning of the first wire, thereby improving the wiring efficiency between the first connector and the first wire.

[0038] In some possible implementations, the sidewall of the third housing has a drain hole, and the bottom of the first housing, the slot, and the drain hole are connected in sequence.

[0039] In the technical solution of this application, the drain hole can be used to discharge liquid or water vapor from the connector assembly in a timely manner, thereby ensuring that the connector assembly can maintain a normal working state.

[0040] In some possible implementations, the first connector further includes a seal for sealing the connection between the first welded portion and the corresponding first wire, the connection between the second welded portion and the corresponding first wire, and the connection between the third welded portion and the corresponding first wire.

[0041] In the technical solution of this application, the sealing element can seal the first wire and each welded part of the first terminal assembly, thereby improving the waterproof sealing between the first wire and the welded part. It can also prevent the first wire layer from falling off the welded part of the first terminal assembly, thereby improving the stability of the connection between the first connector and the first wire.

[0042] In some possible implementations, the first connector further includes a threaded rod and a first limiting plate, one end of which is connected to the outer wall of the first base and extends away from the first base.

[0043] The second connector also includes a second limiting plate, one end of which is connected to the outer wall of the second base and extends away from the second base;

[0044] When the first connector and the second connector are in the plugged-in state, the first limiting plate and the second limiting plate abut against each other.

[0045] In the technical solution of this application, the threaded rod can more conveniently fix the first connector on the corresponding thread, which is convenient for fixing the first connector. At the same time, the first limiting plate and the second limiting plate can limit each other to prevent the second connector from rotating excessively in the screw-in direction, thereby ensuring that the first connector and the second connector are inserted in place and maintain a good electrical connection.

[0046] On the other hand, embodiments of this application also provide a terminal device, the terminal device including a first device body and a first connector as described in any of the connector assemblies in the embodiments of this application above, wherein the first device body and the first connector are electrically connected; and / or,

[0047] The terminal device includes a second device body and a second connector in a connector assembly as described in any of the embodiments of this application above, wherein the second device body is electrically connected to the second device.

[0048] The terminal device provided in this application embodiment can not only use the connector assembly to firmly connect the first device body and the second device body together, but also enable electrical connection between the first device body and the second device body, thereby improving the versatility of the connector assembly's functions.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0065] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0066] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0067] Combination Figure 1 and Figure 2 As shown, this application embodiment provides a connector assembly, which includes a first connector 1 and a second connector 2. The first connector 1 has a slot 11 and a plurality of first wedge teeth 12. The slot 11 has an internal thread 111 on its groove wall. The first wedge teeth 12 are located on the side of the internal thread 111 away from the bottom of the slot 11 and protrude away from the bottom of the slot 11. The second connector 2 has an external thread 21 and a plurality of second wedge teeth 22 protruding toward the bottom of the slot 11. The second wedge teeth 22 are located on the side of the external thread 21 away from the bottom of the slot 11.

[0068] When the first connector 1 and the second connector 2 are in the plugging state, the internal thread 111 and the external thread 21 mesh with each other, and the multiple first wedge teeth 12 and the multiple second wedge teeth 22 mesh with each other.

[0069] The connector assembly provided in this application includes a first connector 1 and a second connector 2. When the first connector 1 and the second connector 2 are in the plugged-in state, they are not only fixed by the mutual engagement of the internal thread 111 of the first connector 1 and the external thread 21 of the second connector 2, but also by the mutual engagement of the first wedge tooth 12 of the first connector 1 and the second wedge tooth 22 of the second connector 2, thus preventing the two connectors from loosening and improving the stability of the connection between the two connectors. Simultaneously, if the first connector 1 is electrically connected to a power supply device and the second connector 2 is electrically connected to a power user device, and the first connector 1 and the second connector 2 are in the plugged-in state, the power supply device can supply power to the power user device through the electrically connected first connector 1 and second connector 2. In other words, the connector assembly provided in this application embodiment can not only securely connect the power user device, but also supply power to the power user device.

[0070] The following is in conjunction with the appendix Figures 1 to 8 The details and functions of the connector assembly provided in the embodiments of this application will be described in more specific and detailed manner.

[0071] like Figure 2 As shown, in some possible embodiments, the slope angle of the helical tooth surface of the second wedge tooth 22 is greater than the thread helix angle of the external thread 21. It should be noted that the slope angles of the helical tooth surfaces of the first wedge tooth 12 and the second wedge tooth 22 are the same, and the thread helix angle of the internal thread 111 is the same as or approximately the same as the thread helix angle of the external thread 21. This allows the first wedge tooth 12 and the second wedge tooth 22 to achieve a more stable meshing, ensuring a secure connection between the first connector 1 and the second connector 2. It should be understood that by setting the slope angle and thread helix angle as described above, it can be ensured that when the internal thread 111 rotates relative to the external thread 21, the first wedge tooth 12 and the second wedge tooth 22 will not rotate relative to each other, thus enabling the first wedge tooth 12 and the second wedge tooth 22 to play an anti-loosening role. The tension between the helical tooth surfaces of the first wedge tooth 12 and the second wedge tooth 22 achieves both anti-loosening and tightening effects. It should be noted that, in the embodiments of this application, the thread helix angle refers to the angle between the tangent of the thread helix and a plane perpendicular to the thread axis. The bevel angle refers to the angle between the beveled tooth surface and a plane perpendicular to the thread axis.

[0072] It should be noted that, in combination Figure 2 and Figure 5As shown, when the second connector 2 is inserted into the first connector 1 and fully inserted, the first wedge tooth 12 is located between two adjacent second wedge teeth 22, and the tip of the second wedge tooth 22 abuts against the vertical side 121 of the first wedge tooth 12 facing the tip. When the second connector 2 is screwed out of the first connector 1 by external force, the second wedge tooth 22 can rotate relative to the first wedge tooth 12 along the screwing direction of the external thread 21. At this time, the first helical tooth surface 221 of the second wedge tooth 22 can rotate relative to the second helical tooth surface 122 of the opposite first wedge tooth 12 to the separation position. When the internal thread 111 separates from the external thread 21, the second connector 2 can be smoothly pulled out of the slot 11 of the first connector 1 to separate from the first connector 1.

[0073] like Figure 3 As shown, in some possible embodiments, a stepped hole 13 is formed at the top of the slot 11. The stepped hole 13 has a first side hole wall 131, a second side hole wall 132, and a bearing surface 133 connected in sequence. The first side hole wall 131 and the second side hole wall 132 both extend parallel to the insertion and extraction direction. The diameter of the first side hole wall 131 is larger than the inner diameter of the internal thread 111 and smaller than the diameter of the second side hole wall 132. The bearing surface 133 intersects the insertion and extraction direction. A plurality of first wedge-shaped teeth 12 are located on the bearing surface 133 and are evenly distributed around the first side hole wall 131 at a preset interval. When the first connector 1 and the second connector 2 are in the insertion state, the outer surface of the second wedge-shaped teeth 22 abuts against the second side hole wall 132. It should be noted that when the second connector 2 is screwed into the first connector 1, the second side hole wall 132 can limit the circumferential movement of the second wedge-shaped teeth 22, thereby preventing the second connector 2 from shifting and ensuring that the second connector 2 can be screwed into place and achieve a stable electrical connection with the first connector 1.

[0074] like Figure 4As shown, in some possible embodiments, the first connector 1 includes a first base 14, a first housing 15, and a first terminal assembly 16. The first base 14 has a slot 11 and a plurality of first wedge-shaped teeth 12. The first housing 15 is located within the slot 11, and the first terminal assembly 16 is located within the first housing 15. The first housing 15 has a first opening 151 facing the slot 11. The contact end of the second connector 2 extends into the first housing 15 through the slot 11 and the first opening 151, and abuts against the first terminal assembly 16. In some embodiments, the first housing 15 includes two interlocking half-housings 152, which, when interlocked, form the first opening 151. It should be noted that the first housing 15 can position the first terminal assembly 16, and the slot 11 can position the first housing 15, thereby improving the assembly efficiency of the first connector 1. The second connector 2, by inserting into the first opening 151, can abut against the first terminal assembly 16 to achieve electrical connection with the first connector 1, thereby also improving the insertion efficiency between the first connector 1 and the second connector 2. In some embodiments, the first housing 15 can engage with the wall of the slot 11. The first terminal assembly 16 can engage with the inner wall of the first housing 15. This improves the assembly efficiency of the first connector 1.

[0075] like Figure 2 As shown, in some possible embodiments, the second connector 2 includes a second base 23, a second housing 24, and a second terminal assembly 25. The second base 23 has a through hole 231 and an external thread 21. The second housing 24 passes through the through hole 231. The second terminal assembly 25 is embedded in the second housing 24. The welding end of the second terminal assembly 25 protrudes from the top of the second housing 24, and the contact end of the second terminal assembly 25 protrudes from the second housing 24. The first base 14 and the second base 23 can both be made of metal. The second housing 24, the second base 23, and the second terminal assembly 25 can be injection molded into a single structure. When the first connector 1 and the second connector 2 are in the insertion state, the portion of the second housing 24 extending out of the through hole 231 is located within the first housing 15, and the contact end of the second terminal assembly 25 abuts against the first terminal assembly 16. It should be noted that the second housing 24 can fix the second terminal assembly 25. When the contact end of the second terminal assembly 25 abuts against the first terminal assembly 16, the first connector 1 and the second connector 2 are electrically connected through the first terminal assembly 16 and the second terminal assembly 25.

[0076] like Figure 4 and Figure 8As shown, in some possible embodiments, the first terminal assembly 16 includes a first crown spring terminal 161, a second crown spring terminal 162, and a third crown spring terminal 163 sequentially distributed along the insertion direction. The first crown spring terminal 161 includes a first contact portion 1611 and a first welding portion 1612; the second crown spring terminal 162 includes a second contact portion 1621 and a second welding portion 1622; and the third crown spring terminal 163 includes a third contact portion 1631 and a third welding portion 1632. The first contact portion 1611, the second contact portion 1621, and the third contact portion 1631 are coaxially arranged and sleeved on the contact end of the second terminal assembly 25. The first welding portion 1612, the second welding portion 1622, and the third welding portion 1632 respectively protrude from the side wall of the second housing 24 and are electrically connected to the corresponding first wire 3. It should be noted that the first wire 3 corresponding to the first welding portion 1612, the second welding portion 1622, and the third welding portion 1632 can be a ground wire, a live wire, and a neutral wire, respectively.

[0077] Since the first terminal assembly 16 includes three crown spring terminals, the contact area between the first terminal assembly 16 and the contact end of the second terminal assembly 25 can be increased. Thus, when the soldered parts of the three crown spring terminals are electrically connected to the corresponding first wires 3, and the contact parts of the three crown spring terminals abut against the contact end of the second terminal assembly 25, the current carrying capacity of the connector assembly can be increased.

[0078] Combination Figure 2 and Figure 6 As shown, in some possible embodiments, the second terminal assembly 25 includes a first terminal 251, a third terminal 253252, and a third terminal extending along the insertion direction. The third terminal 253252 is disposed around the first terminal 251, and the third terminal is disposed around the third terminal 253252. The first terminal 251 can be manufactured by CNC machining, and the third terminal 253252 and the third terminal can be manufactured by a drawing process.

[0079] The first terminal 251 includes a fourth contact portion 2511 and a fourth welding portion 2512, the third terminal 253252 includes a fifth contact portion 2521 and a fifth welding portion 2522, and the third terminal includes a sixth contact portion 2531 and a sixth welding portion 2532.

[0080] The fourth welding part 2512, the fifth welding part 2522 and the sixth welding part 2532 are electrically connected to the corresponding second wires 4. The fourth contact part 2511 extends through the bottom of the second housing 24, and the fifth contact part 2521 and the sixth contact part 2531 extend through the side wall of the second housing 24, with the fifth contact part 2521 located between the fourth contact part 2511 and the sixth contact part 2531.

[0081] The fourth contact portion 2511 abuts against the inner wall of the third crown spring terminal 163, the fifth contact portion 2521 abuts against the inner wall of the second crown spring terminal 162, and the sixth contact portion 2531 abuts against the inner wall of the first crown spring terminal 161. It should be noted that the abutment of the inner wall of the crown spring terminal with the corresponding contact portion increases the contact area between the first terminal assembly 16 and the second terminal assembly 25, thereby increasing the current-carrying capacity of the connector assembly. Simultaneously, due to the elasticity of the crown spring terminal, it can also provide inward pressure to the corresponding contact portion, thus ensuring a stable electrical connection between the first connector 1 and the second connector 2. It should be noted that the second conductor 4 corresponding to the fourth solder portion 2512, the fifth solder portion 2522, and the sixth solder portion 2532 can be the neutral wire, the live wire, and the ground wire, respectively. In some embodiments, the second connector 2 further includes a sealing block 27, which seals the connection between the second conductor 4 and the corresponding contact portion, improving the sealing performance of the second connector 2.

[0082] Combination Figure 6 and Figure 7 As shown, in some possible embodiments, the diameter of the first terminal 251 gradually increases in the direction from the fourth welding portion 2512 to the fourth contact portion 2511. It should be noted that the gradually increasing diameter of the first terminal 251 can improve the bending resistance of the second connector 2, thereby improving the strength and reliability of the second connector 2. In some embodiments, the first terminal 251 includes a first segment 2513, a second segment 2514, a third segment 2515, and a fourth segment 2516 connected in sequence. The second segment 2514 is frustoconical, and its diameter gradually increases in the insertion direction. The diameter of the first segment 2513 is smaller than the minimum diameter of the second segment 2514, the diameter of the third segment 2515 is larger than the maximum diameter of the second segment 2514, and the diameter of the fourth segment 2516 is larger than the diameter of the third segment 2515 and equal to the outer diameter of the second housing. The fourth segment 2516 can protrude from the bottom of the second housing. This configuration improves the bending resistance of the first terminal 251. In some embodiments, the diameter of the third terminal 253252 gradually increases in the insertion direction, and the diameter of the third terminal also gradually increases in the insertion direction. This improves the bending resistance of the third terminal 253252 and the third terminal, thereby increasing the strength of the second connector 2.

[0083] Combination Figure 6As shown, in some possible implementations, any one of the first terminal 251, the third terminal 252, and the third terminal is a detection terminal, and the one corresponding to the detection terminal among the first crown spring terminal 161, the second crown spring terminal 162, and the third crown spring terminal 163 is the target terminal. The detection terminal is used to send a current conduction signal when it comes into contact with the target terminal. It should be noted that the first wire 3 can be electrically connected to the power supply equipment, the second wire 4 can be electrically connected to the power consumption equipment, and the power supply equipment can be electrically connected to the controller used to control the current output state. When the first connector 1 and the second connector 2 are not plugged in, only the detection terminal is energized. When the detection terminal comes into contact with the target terminal, the detection terminal can send a current conduction signal to the controller. In response to receiving the current conduction signal, the controller outputs current to the second wire 4 corresponding to the two terminals other than the detection terminal, thereby enabling the two terminals other than the detection terminal to achieve electrical connection with the corresponding crown spring terminals, so that the power supply equipment can supply power to the power consumption equipment. It should be understood that the detection terminal can be the first terminal 251 connected to the neutral wire, and the target terminal can be the third crown spring terminal 163 connected to the neutral wire. The detection terminal can be used for charging detection and protocol communication. The third terminal 253 / 252 can be a power supply terminal. The third terminal can also be a grounding terminal. It should be noted that the first crown spring terminal 161, the second crown spring terminal 162, and the third crown spring terminal 163 have the same structural dimensions, which facilitates the improvement of the processing efficiency of the first connector 1.

[0084] Combination Figure 3 and Figure 4 As shown, in some possible embodiments, the first connector 1 further includes a third housing 17. The sidewall of the first base 14 has a second opening 141. The first housing 15 extends into the slot 11 through the second opening 141. The third housing 17 engages with the side of the first housing 15 facing the first opening 141 and is connected to the first base 14. A wiring hole 171 communicating with the interior of the first housing 15 is formed between the third housing 17 and the first housing 15. The wiring hole 171 is used to accommodate the corresponding first wire 3. This arrangement allows the first terminal assembly 16 to be assembled with the first housing 15 first, and then the first housing 15 to be extended into the slot 11 through the second opening 141, thus improving the assembly efficiency of the first connector 1. Furthermore, the wiring hole 171 formed by the first housing 15 and the third housing 17 facilitates the positioning of the first wire 3, thereby improving the wiring efficiency between the first connector 1 and the first wire 3.

[0085] like Figure 4As shown, in some possible embodiments, the side wall of the third housing 17 has a drain hole 172, and the bottom of the first housing 15, the slot 11, and the drain hole 172 are sequentially connected. The drain hole 172 allows liquids or moisture inside the connector assembly to be discharged in a timely manner, thereby ensuring that the connector assembly maintains its normal operating condition.

[0086] like Figure 4 As shown, in some possible embodiments, the first connector 1 further includes a seal 18, which is used to seal the connection between the first welded part 1612 and the corresponding first wire 3, the connection between the second welded part 1622 and the corresponding first wire 3, and the connection between the third welded part 1632 and the corresponding first wire 3. It should be understood that the seal 18 can seal both the first wire 3 and each welded part of the first terminal assembly 16, improving the waterproof sealing between the first wire 3 and the welded part, and also preventing the first wire 3 from detaching from the welded part of the first terminal assembly 16, thereby improving the stability of the connection between the first connector 1 and the first wire 3.

[0087] like Figure 4 As shown, in some possible embodiments, the first connector 1 further includes a threaded rod 19 and a first limiting plate 20. One end of the first limiting plate 20 is connected to the outer wall of the first base 14 and extends away from the first base 14. The second connector 2 further includes a second limiting plate 26. One end of the second limiting plate 26 is connected to the outer wall of the second base 23 and extends away from the second base 23. When the first connector 1 and the second connector 2 are in the insertion state, the first limiting plate 20 and the second limiting plate 26 abut against each other. It should be noted that the threaded rod 19 can more conveniently fix the first connector 1 onto the corresponding thread, for example, by installing the threaded rod 19 in the threaded hole of the vehicle's trim piece, thereby making it easier to fix the first connector 1. At the same time, the first limiting plate 20 and the second limiting plate 26 can limit each other, preventing the second connector 2 from rotating excessively in the screw-in direction, thereby ensuring that the first connector 1 and the second connector 2 are properly inserted and maintain a good electrical connection.

[0088] In summary, the connector assembly provided in this application not only enables electrical connection between the device connected to the first connector 1 and the device connected to the second connector 2, but also utilizes the threaded engagement and wedge-shaped tooth engagement of the first connector 1 and the second connector 2 to securely connect the device connected to the second connector 2 to the first connector 1, thereby stabilizing the installation position of the device connected to the second connector 2. For example, the device electrically connected to the first connector 1 can be a power supply device in a vehicle, and the device electrically connected to the second connector 2 can be an electrical device such as a mobile phone holder that powers electronic devices such as mobile phones. The vehicle can have a pre-drilled threaded hole for installing the first connector 1, and the threaded rod 19 at the bottom of the first base 14 can be screwed into the pre-drilled threaded hole in the vehicle, thereby fixing the first connector 1 to the vehicle. The electrical device can be equipped with a second connector 2. When the external thread 21 of the second connector 2 is screwed into the internal thread 111, and the second wedge tooth 22 engages with the first wedge tooth 12, the electrical device can be stably fixed on the vehicle and power can be supplied to the device. In this way, electrical devices such as mobile phone holders can supply power to mobile phones and other terminals, expanding the functionality of the vehicle-mounted mobile phone holder. Furthermore, the wiring terminal can abut against the inner wall of the corresponding crown spring terminal. Because the contact area of ​​the crown spring is large, the current carrying capacity of the connector assembly can be improved, thereby increasing the charging rate of the electrical device.

[0089] Combination Figures 1 to 8 As shown, on the other hand, embodiments of this application also provide a terminal device, which includes a first device body and a first connector 1 in the connector assembly as described in any of the above embodiments of this application, wherein the first device body and the first connector 1 are electrically connected. And / or, the terminal device includes a second device body and a second connector 2 in the connector assembly as described in any one of the above embodiments of this application, wherein the second device body and the second device are electrically connected. It should be noted that the terminal device may be, for example, a vehicle, and the first device body may be, for example, a power supply device in the vehicle. The second device body may be, for example, a power supply device such as a mobile phone holder that supplies power to electronic devices such as mobile phones, so that the mobile phone holder can supply power to the mobile phone to realize the charging function, or it may be a device that needs to be charged, such as a mobile phone, tablet, or smart wearable device, so that the power supply device can directly charge the second device body. Under normal conditions, the first connector 1 and the first device body can always remain in a fixed state, and the second connector 2 and the second device body can always remain in a fixed state. This can improve the functionality of the threaded hole reserved on the vehicle for threaded connection with the threaded rod 19, which may be, for example, a 1 / 4 threaded hole on the interior trim of the vehicle. After the first connector 1 and the second connector 2 are in the plugged state, they can both supply power to the second device body and prevent the first connector 1 and the second connector 2 from becoming loose, thereby stably installing the second device body on the terminal device with the reserved threaded hole.
