[0001] This utility model relates to the field of power supply technology, specifically to wire connection components and power supply devices. Background Technology

[0002] With the widespread use of electronic devices and the ever-increasing demand for electricity, power supply devices have become an indispensable infrastructure in modern life. People widely use various power supply devices, such as chargers, adapters, and power banks, to meet the diverse power supply needs of everything from smartphones to industrial equipment.

[0003] Existing power supply devices typically consist of wires and circuit boards. The wires are soldered onto the circuit board to transmit electrical energy. However, in actual operation, users need to strip the insulation layer of the wires and then tin the exposed wires. This operation is not only cumbersome, but also prone to unstable soldering quality due to improper operation.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

The connector assembly includes a wire at one end and a conductor at the other end connected to the wire. The conductor extends into the receiving cavity and is soldered to the circuit board.

[0009] Furthermore, the lower housing includes a connecting through hole communicating with the accommodating cavity, and the anti-rotation mechanism includes an anti-rotation groove located on the side of the stress relief portion near the conductor, and an anti-rotation protrusion located on the connecting through hole and inserted into the anti-rotation groove.

[0010] Furthermore, the anti-loosening mechanism includes an anti-loosening groove located on the side of the stress relief section near the conductor, and an anti-loosening buckle located on the side of the upper box near the receiving cavity and engaging with the anti-loosening groove. The anti-loosening buckle extends from the upper box towards the lower box.

[0011] Furthermore, the stress relief portion extends obliquely and is arc-shaped near the conductor.

[0012] Furthermore, the stress relief part is provided with a mounting groove, and a waterproof sealing ring is provided on the mounting groove.

[0013] Furthermore, the inner side wall of the lower box is provided with a limiting protrusion, and the stress relief part is provided with a limiting groove that engages with the limiting protrusion.

[0014] The conductor has an extension connection portion, which protrudes towards the circuit board and is cylindrical in shape. The circuit board has a connection hole corresponding to the extension connection portion, and the extension connection portion passes through the connection hole and is soldered to the circuit board.

[0015] This invention also provides a power supply device, including the wire connection assembly described above.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features a connecting connector assembly, which includes an electric wire and a conductor.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 9 The wire connection assembly shown includes a housing 1 and a connector assembly 2. The housing 1 has a receiving cavity 3, and the receiving cavity 3 has a circuit board 4. The connector assembly 2 includes a wire 21 at one end and a conductor 22 at the other end and connected to the wire 21. The conductor 22 extends into the receiving cavity 3 and is soldered to the circuit board 4.

[0030] This invention features a connecting connector assembly, which includes an electric wire and a conductor. The electric wire and conductor are connected, and the conductor can be standardized during the manufacturing process. Users can directly insert the conductor into the receiving cavity to solder it to the circuit board, which helps to eliminate tedious processes such as wire stripping and tinning, improves soldering efficiency, and ensures soldering quality.

[0031] Furthermore, by setting conductor 22, conductor 22 can extend into the receiving cavity 3 and be directly soldered to circuit board 4. Compared with the existing wire soldering process, it is beneficial to avoid the difficulties in wire threading and soldering caused by the shortness of the reserved wire material. The length of conductor 22 can be standardized during the manufacturing process to ensure that users can easily extend conductor 22 directly into the receiving cavity 3 and complete the soldering with circuit board 4, thereby significantly improving work efficiency.

[0032] Furthermore, the conductor 22 can be standardized during the manufacturing process, so that the external dimensions, end shape and pin spacing of the conductor 22 connected to the circuit board 4 can be uniform, which not only ensures the stability of the welding between the conductor 22 and the circuit board 4, but also effectively improves the welding efficiency.

[0033] Furthermore, in existing wire welding processes, users typically leave excessively long wires 21 to ensure that the wires 21 can pass smoothly through the connection holes on the circuit board 4 and complete the welding. However, this practice not only wastes wire materials but may also cause excessively long wires to come into contact with other components, thereby affecting safety distances and posing safety hazards. This utility model, by setting a conductor 22, can extend into the receiving cavity 3 and be directly welded to the circuit board 4, eliminating the need to leave excess wire materials. This not only saves resources but also avoids the impact of excessively long wires on safety distances, thereby improving the safety and reliability of the circuit board 4 assembly.

[0034] Furthermore, the housing 1 provides physical protection for the soldering points of the internal circuit board 4 and conductor 22. The housing 1 can prevent damage to the circuit board 4 and soldering points caused by collisions and scratches from external objects, reduce the risk of failures such as loose soldering and broken wires due to accidental impacts, and effectively extend the service life of the equipment.

[0035] Optionally, in some embodiments, the conductor 22 is a hard metal sheet, such as a copper alloy stamped pin or blade, with barbs or protrusions at the end of the conductor 22. The circuit board 30 is provided with preset solder holes or sockets, and the conductor 22 can be directly inserted into the preset solder holes or sockets and fixed by soldering.

[0036] Optionally, in some embodiments, conductor 22 is a composite insulated conductor with an inner copper core and an outer layer covered with a high-temperature resistant insulating material, such as polytetrafluoroethylene. Only one end of conductor 22 near circuit board 4 is exposed. Circuit board 22 has a pre-set connecting hole 41. The exposed part of conductor 22 passes through the connecting hole 41 and is fixed by welding.

[0037] Specifically, the wire 21 on one side of the box 1 is connected to the power input terminal 201, and the wire 21 on the other side of the box 1 is connected to the power output terminal 202. By placing the power input terminal 201 and the power output terminal 202 on the two sides of the box 1 respectively, mutual interference between the input and output wires can be avoided. Users can more clearly distinguish between the input power and the output power during installation, which helps to reduce the risk of incorrect wiring.

[0038] like Figures 1 to 9 The connector assembly 2 shown includes a stress relief part 23 that is integrally injection molded and located between the wire 21 and the conductor 22;

[0039] Specifically, the wire 21 and conductor 22 are first connected together, and then the stress relief part 23 is integrally injection molded on the outside of a local area of ​​the wire 21 and conductor 22 to make the connection between the wire 21 and conductor 22 more stable. The stress relief part 23 can effectively prevent the wire 21 from loosening or separating from the conductor 22 due to frequent bending, stretching or twisting during daily use.

[0040] Furthermore, the wire 21 will inevitably bend during use, and the integrally injection-molded stress relief part 23 can enhance the flexibility and bending resistance of the connection between the wire 21 and the conductor 22. The stress relief part 23 can buffer the stress generated during bending and reduce the risk of breakage of the internal wires of the wire 21.

[0041] Furthermore, the stress relief part 23 can enhance the connection stability between the wire 21 and the conductor 22, ensuring that they always maintain good electrical contact, which helps to reduce changes in contact resistance. Stable contact resistance helps to reduce power loss and effectively improve power transmission efficiency. At the same time, it can also reduce safety hazards such as overheating and arcing caused by poor contact.

[0042] Optionally, the stress relief part 23 may be made of polyvinyl chloride (PVC), a common plastic material with a relatively low price. PVC has a certain mechanical strength, provides good stress relief, and also has good electrical insulation properties.

[0043] Optionally, the stress relief part 23 may be made of semi-rigid polyvinyl chloride (PVC), which is harder than ordinary PVC and has higher tensile strength.

[0044] Optionally, the stress relief part 23 may be made of rubber material. Rubber has excellent flexibility, elasticity and tear resistance, which can effectively buffer the impact of external forces on the connection between the wire 21 and the conductor 22, reduce stress concentration. At the same time, rubber has good insulation properties, which can effectively prevent current leakage.

[0045] Optionally, the stress relief part 23 can be made of ABS (acrylonitrile-butadiene-styrene copolymer). ABS material has high tensile strength and impact strength, and can withstand large mechanical stress, ensuring that the stress relief part 23 will not be damaged by external forces during use. Secondly, ABS material has good toughness, and can maintain structural integrity under a certain degree of bending and twisting, reducing the risk of breakage caused by mechanical vibration or external forces. Finally, ABS material has good flowability, which is suitable for injection molding process, and can accurately manufacture complex shapes and structures.

[0046] like Figures 1 to 9 The box 1 shown includes an upper box 11 and a lower box 12, which are connected to form the receiving cavity 3. The stress relief part 23 extends through the lower box 12 into the receiving cavity 3. An anti-rotation mechanism 51 is provided between the lower box 12 and the stress relief part 23, and an anti-loosening mechanism 52 is provided between the upper box 11 and the stress relief part 23.

[0047] Furthermore, the anti-rotation mechanism 51 is provided between the lower housing 12 and the stress relief part 23, which can effectively prevent the stress relief part 23 from rotating during use.

[0048] Furthermore, the anti-loosening mechanism 52 is disposed between the upper housing 11 and the stress relief part 23, which can prevent the stress relief part from loosening from the housing, thereby further enhancing the mechanical stability of the entire device.

[0049] Optionally, the upper box 11 and the lower box 12 can be connected by threaded connection, snap-fit ​​connection, slot connection, or other connection methods.

[0050] Optionally, in some embodiments, the anti-rotation mechanism 51 includes one or more pin holes located on the inner sidewall of the lower housing 12, and a pin located on the outer sidewall of the stress relief part 23 and corresponding to the pin holes. When the stress relief part 23 is inserted into the lower housing 12, the pin is inserted into the pin hole to restrict the rotation of the stress relief part 23.

[0051] Optionally, in some embodiments, the hole through which the stress relief part 23 passes on the lower box 12 is a polygon, such as a triangle, quadrilateral, hexagon, etc., and the connection between the stress relief part 23 and the lower box 12 is correspondingly set as a polygon. The sides of the polygons restrict each other to limit the rotation of the stress relief part 23.

[0052] Preferably, and not limited to, the lower housing 12 includes a connecting through hole 121 communicating with the accommodating cavity 3, and the anti-rotation mechanism 51 includes an anti-rotation groove 511 located on the side of the stress relief part 23 near the conductor 22, and an anti-rotation protrusion 512 located on the connecting through hole 121 and inserted into the anti-rotation groove 511.

[0053] Optionally, in some embodiments, the anti-loosening mechanism 52 includes one or more pins located on the outer wall of the stress relief part 23 and one or more pin holes located on the inner wall of the upper box 11. The pins extend from the lower box 12 toward the upper box 11. When the stress relief part 23 extends into the receiving cavity 3, the upper box 11 and the lower box 12 are closed. At this time, the pins on the stress relief part 23 are engaged with the pin holes on the inner wall of the upper box 11, thereby preventing the stress relief part from loosening.

[0054] Optionally, in some embodiments, the anti-loosening mechanism 52 includes a wedge-shaped block located on the inner sidewall of the upper box 11 and an inclined structure located on the stress relief part 23. The wedge-shaped block has an inclined surface that matches the inclined structure. When the upper box 11 and the lower box 12 are closed, the inclined surface of the wedge-shaped block and the inclined surface on the stress relief part 23 are pressed against each other. As the closing process proceeds, the wedge-shaped block gradually penetrates deeper, pressing the stress relief part 23 tightly. Through the friction between the inclined surfaces and the wedge-shaped action, the stress relief part 23 is prevented from loosening.

[0055] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the anti-loosening mechanism 52 includes an anti-loosening groove 521 located on the side of the stress relief part 23 near the conductor 22, and an anti-loosening buckle 522 located on the side of the upper box 11 near the receiving cavity 3 and engaging with the anti-loosening groove 521.

[0056] like Figures 1 to 9 The lower housing 12 shown includes a connecting through hole 121 communicating with the accommodating cavity 3. The anti-rotation mechanism 51 includes an anti-rotation groove 511 located on the side of the stress relief part 23 near the conductor 22, and an anti-rotation protrusion 512 located on the connecting through hole 121 and inserted into the anti-rotation groove 511.

[0057] Furthermore, the insertion and engagement of the anti-rotation groove 511 and the anti-rotation protrusion 512 can physically prevent the stress relief part 23 from rotating relative to the lower housing 12. When the equipment is affected by external forces, vibrations, or other factors that may cause the stress relief part 23 to rotate during operation, this structure can ensure that the position of the stress relief part 23 is fixed, thus ensuring the mechanical stability of the entire device.

[0058] Furthermore, the connection through hole 121, the anti-rotation groove 511, and the anti-rotation protrusion 512 make the installation process of the stress relief part 23 simpler and more intuitive. Users only need to insert the stress relief part 23 into the connection through hole 121 and ensure that the anti-rotation protrusion 512 is correctly embedded in the anti-rotation groove 511 to complete the assembly, which helps to reduce assembly steps and time and effectively improve production efficiency.

[0059] Furthermore, the cross-section of the anti-rotation groove 511 is in the shape of an "eight". The opening of the "eight"-shaped groove has a natural expanding shape. When installing the stress relief part 23, the anti-rotation protrusion 512 is easier to align with the anti-rotation groove 511. Even if there is a certain positional deviation during the installation process, the "eight"-shaped groove can also play a guiding role, allowing the anti-rotation protrusion 512 to slide into the anti-rotation groove 511 along the inclined surface of the groove, reducing the installation difficulty and improving the installation efficiency. Secondly, after the "eight"-shaped anti-rotation groove 511 and the anti-rotation protrusion 512 are combined, they can provide anti-rotation constraints in multiple directions, which helps to enhance the anti-rotation effect.

[0060] like Figures 1 to 9 The anti-loosening mechanism 52 shown includes an anti-loosening groove 521 located on the side of the stress relief part 23 near the conductor 22, and an anti-loosening buckle 522 located on the side of the upper box 11 near the receiving cavity 3 and engaged with the anti-loosening groove 521. The anti-loosening buckle 522 extends from the upper box 11 toward the lower box 12.

[0061] Furthermore, the engagement of the anti-loosening groove 521 and the anti-loosening buckle 522 can effectively prevent the stress relief part 23 from being released from the anti-loosening buckle 522. When the stress relief part 23 is inserted into the lower box 12 and the upper box 11 is closed with the lower box 12, the anti-loosening buckle 522 is engaged in the anti-loosening groove 521, thereby fixing the position of the stress relief part 23 and preventing it from loosening during use.

[0062] Furthermore, the anti-loosening buckle 522 extends from the upper box 11 toward the lower box 12, which can achieve the anti-loosening function in a limited space, avoiding the need for excessive space due to additional anti-loosening structures, so as to make the structure of the whole device more compact.

[0063] Furthermore, the extension of the anti-loosening buckle 522 plays a guiding role in the installation process. During installation, simply align the upper box 11 with the lower box 12, and the anti-loosening buckle 522 will gradually insert into the anti-loosening groove 521 in a certain direction, making the installation process smoother and reducing installation time and operation difficulty.

[0064] like Figures 1 to 9 The stress relief section 23 shown extends obliquely and is arranged in an arc shape near the conductor 22;

[0065] Furthermore, the arc shape can effectively disperse stress and avoid stress concentration. Under mechanical vibration or external force, the stress will be evenly distributed along the arc surface, rather than concentrated at a certain point.

[0066] Furthermore, the arc-shaped structure has a natural curved shape. When the stress relief part 23 approaches the connecting through hole 121, its arc-shaped front end can play a guiding role, so that the stress relief part 23 can smoothly pass through the connecting through hole 121 and enter the lower box 12. Compared with the straight-shaped stress relief part, the arc-shaped setting can avoid rigid collision or interference with the edge of the connecting through hole 121 during the insertion process.

[0067] Furthermore, since the arc-shaped stress relief part 23 can more easily extend into the connecting through hole 121, the installer does not need to spend too much time adjusting the position and angle of the stress relief part 23 during the assembly operation, thereby greatly improving the installation speed.

[0068] like Figures 1 to 9 The stress relief part 23 shown is provided with a mounting groove, and a waterproof sealing ring 231 is provided on the mounting groove;

[0069] Furthermore, the waterproof sealing ring 231 is installed in the mounting groove of the stress relief part 23. When the stress relief part 23 is inserted into the connecting through hole 121 of the lower housing 12, the waterproof sealing ring 231 can fit tightly against the inner wall of the connecting through hole 121 to form an effective waterproof seal, effectively preventing moisture from entering the accommodating cavity 3 and protecting the internal circuit board 4 and conductor 22 from the influence of the humid environment.

[0070] Furthermore, the waterproof sealing ring 231 not only provides waterproofing but also effectively prevents dust and other particles from entering the accommodating cavity 3, reducing dust contamination of internal components, extending the service life of the equipment, ensuring that the internal circuit board 4 and conductor 22 operate in a clean environment, and improving electrical performance.

[0071] Furthermore, the waterproof sealing ring 231 can provide a certain mechanical support in the installation groove, reducing the shaking of the stress relief part 23 in the connecting through hole 121, which is conducive to improving the mechanical stability of the equipment and reducing poor contact or damage caused by mechanical vibration.

[0072] like Figures 1 to 9 The inner wall of the lower box 12 shown is provided with a limiting protrusion 531, and the stress relief part 23 is provided with a limiting groove 532 that engages with the limiting protrusion 531.

[0073] Furthermore, the snap-fit ​​between the limiting protrusion 531 and the limiting groove 532 can effectively limit the position of the stress relief part 23 within the lower housing 12, preventing it from loosening or shifting during use. Through the limitation of the physical structure, the risk of poor contact or damage to the welding point caused by loosening is reduced, thereby improving the reliability of the entire device.

[0074] Furthermore, the limiting function can be achieved by the snap-fit ​​of the limiting protrusion 531 and the limiting groove 532, without the need for additional complex parts or processes, which helps to reduce manufacturing costs, reduce the use of additional parts, and effectively reduce material and assembly costs.

[0075] like Figures 1 to 9 The conductor 22 shown is provided with an extension connection portion 221. The extension connection portion 221 protrudes towards the circuit board 4 and is cylindrical. The circuit board 4 is provided with a connection hole 41 corresponding to the extension connection portion 221. The extension connection portion 221 passes through the connection hole 41 and is soldered to the circuit board 4.

[0076] Furthermore, the extension connection 221 passes through the connection hole 41 for welding, which can ensure that the extension connection 221 and the circuit board 4 form a good electrical contact. The welding process can make the extension connection 221 and the circuit board 4 tightly bonded, reduce contact resistance, reduce signal attenuation and heat generation caused by poor contact, and improve the reliability and stability of the circuit connection.

[0077] Furthermore, the way the cylindrical extension connection 221 and the connecting hole 41 are fitted together gives the extension connection 221 good mechanical stability after it is inserted into the connecting hole 41. During the welding process, the solder can fully fill the gap between the extension connection 221 and the connecting hole 41 to form a strong connection structure, which is beneficial to improving the connection strength between the circuit board 4 and the conductor 22 and ensuring the normal operation of the equipment in complex environments.

[0078] Furthermore, the cylindrical extension connection 221 matches the shape of the connecting circular hole 41. When the extension connection 221 is inserted into the connecting circular hole 41, the inner wall of the connecting circular hole 41 can play a clear guiding role, so that the extension connection 221 can quickly and accurately reach the designated position on the circuit board 4, avoiding electrical connection problems caused by installation deviation.

[0079] Specifically, the extension connection 221 passes through the connection hole 41 vertically from bottom to top.

[0080] like Figures 1 to 9 The power supply device shown includes the wire connection assembly as described above;

[0081] Specifically, applying the aforementioned wire connection components to power supply devices can improve their stability, ensuring stable operation in various complex environments. Secondly, it facilitates efficient and stable power transmission, effectively reducing electromagnetic interference and other issues. Thirdly, in terms of protection, excellent waterproof and dustproof features create a reliable protective barrier for the power supply device, reducing the risk of malfunctions caused by moisture and dust intrusion. Finally, the assembly process is greatly simplified, allowing users to assemble the power supply device more quickly and accurately, saving time and labor costs.

The pins extend from the lower box 12 toward the upper box 11. When the stress relief part 23 extends into the accommodating cavity 3, the upper box 11 and the lower box 12 are closed. At this time, the pins on the stress relief part 23 are engaged with the pin holes on the inner wall of the upper box 11, thereby preventing the stress relief part from loosening.

[0110] The implementation method of Example Fourteen is as follows:

[0111] The difference between Embodiment Fourteen and Embodiment Five is that the anti-loosening mechanism 52 includes a wedge-shaped block located on the inner wall of the upper box 11 and an inclined structure located on the stress relief part 23. The wedge-shaped block has an inclined surface that matches the inclined structure. When the upper box 11 and the lower box 12 are closed, the inclined surface of the wedge-shaped block and the inclined surface on the stress relief part 23 are pressed against each other. As the closing process proceeds, the wedge-shaped block gradually penetrates deeper and tightly presses the stress relief part 23. Through the friction between the inclined surfaces and the wedge-shaped action, the stress relief part 23 is prevented from loosening.
