Connectors and electrical equipment Technical Field
[0001] This application belongs to the field of connector technology, and particularly relates to a connector and electrical equipment. Background Technology
[0002] In related technologies, the connectors used at the input ports of electrical equipment are usually fastened to the panel of the electrical equipment by the threads and nuts on the housing. Since errors are inevitable in the manufacturing and assembly process of circuit boards and panels, the reliability of the electrical connection between the connector and the circuit board is affected by the stress caused by the positional error. Summary of the Invention
[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a connector and electrical device that compensates for positional errors between the panel and the circuit board of the electrical device, enabling a direct connection between the second conductor and the circuit board.
[0004] In a first aspect, this application provides a connector for use in electrical equipment, comprising:
[0005] A fixed housing having a mounting structure for mounting the connector to a panel of the electrical equipment;
[0006] A first conductor is disposed in the fixed housing for electrical connection with external equipment;
[0007] A floating housing is slidably mounted on the fixed housing along the axial direction of the fixed housing;
[0008] The second conductor is installed on the floating housing and is used for electrical connection with the circuit board of the electrical equipment;
[0009] A flexible component is disposed within the fixed housing and electrically connected between the first conductor and the second conductor.
[0010] According to the connector of this application, through the arrangement of the first conductor, the second conductor, and the flexible component, the flexible component can effectively compensate for the positional error between the panel and the circuit board of the electrical equipment. It eliminates the need for a soft wire to be connected to the end of the connector, realizing the direct connection between the second conductor and the circuit board, which significantly simplifies the installation process. At the same time, it reduces the number of wires required for the entire electrical equipment. The electrical equipment no longer needs to reserve a large space to meet the bending radius requirements of numerous wires, thereby reducing material and labor costs and realizing the miniaturization and compact design of the electrical equipment. In addition, compared with the use of elastic components such as metal springs for tolerance, the flexible component will not cause additional stress to the first and second conductors and can achieve a wider range of floating, thereby greatly improving the reliability and stability of the connector and extending the service life of the connector.
[0011] According to one embodiment of this application, the first conductor and the fixed housing are coaxially arranged, and the first conductor and the second conductor are staggered in both the axial and radial directions of the fixed housing. The flexible member is arranged between the first conductor and the second conductor in a configuration having at least one curved portion.
[0012] According to the connector of this application, through the bias design of the first conductor and the second conductor, combined with the curling design of the flexible component, a larger curling and storage space is provided between the first conductor and the second conductor for the flexible component, which increases the limit length of the flexible component, further enhances the floating ability of the connector, and enables the flexible component to be effectively distributed in a limited space, thereby improving the space utilization of the connector.
[0013] According to one embodiment of this application, the connector further includes:
[0014] A temperature sampling structure, installed on the floating housing, is used to collect the temperature of the second conductor.
[0015] According to the connector of this application, by integrating the temperature sampling structure into the connector as described above, the loss and interference in the heat transfer process are reduced, thereby achieving accurate and timely acquisition of the temperature of the second conductor, and simplifying the assembly process of electrical equipment, thereby reducing assembly complexity and assembly cost.
[0016] According to one embodiment of this application, the floating housing defines a first cavity and a second cavity separated by an insulating wall, the second conductor portion is mounted in the first cavity, and the temperature sampling structure portion is mounted in the second cavity.
[0017] According to the connector of this application, by introducing an insulating wall within the floating housing to form independent first and second cavities, the risk of high voltage leakage from the second conductor to the area where the temperature sampling structure is located is effectively reduced, significantly mitigating strong and weak current coupling interference caused by leakage, thereby improving the reliability of the connector and thus the reliability of the entire electrical equipment. At the same time, it reduces electromagnetic interference generated by strong electrical signals through conduction or radiation to the temperature sampling structure, further improving the accuracy of temperature sampling and maintaining the stable operation of the electrical equipment.
[0018] According to one embodiment of this application, the insulating wall is part of the floating shell.
[0019] According to one embodiment of this application, at least a portion of the temperature sampling structure is covered with an insulating encapsulation layer.
[0020] According to one embodiment of this application, the insulating encapsulation layer is made of a soft material and is filled between the temperature sampling structure and the wall of the second cavity.
[0021] According to one embodiment of this application, the second conductor is provided with a first limiting structure and a second limiting structure, and the floating shell is provided with a third limiting structure and a fourth limiting structure. The first limiting structure and the third limiting structure cooperate to restrict the second conductor from moving toward the first conductor, and the second limiting structure and the fourth limiting structure cooperate to restrict the second conductor from moving away from the first conductor.
[0022] According to one embodiment of this application, the flexible element is welded to the first conductor and the second conductor, and the circuit board is welded to the second conductor.
[0023] Secondly, this application provides an electrical device comprising:
[0024] Panels and circuit boards;
[0025] The connector, as described above, is mounted on the panel via the mounting structure, and the second conductor and temperature sampling structure of the connector are electrically connected to the circuit board.
[0026] According to the electrical equipment of this application, the flexible component can effectively compensate for the positional error between the panel and the circuit board by setting the connector as described above. It eliminates the need to connect a soft wire at the end of the connector, realizing the direct connection between the second conductor and the circuit board, which significantly simplifies the installation process. At the same time, it reduces the number of wires required for the entire electrical equipment. The electrical equipment no longer needs to reserve a large space to meet the bending radius requirements of numerous wires, thereby reducing material and labor costs. It also realizes the miniaturization and compact design of the electrical equipment. In addition, compared with the use of elastic components such as metal springs for tolerance, the flexible component will not cause additional stress to the first and second conductors, and can achieve a wider range of floating, thereby greatly improving the reliability and stability of the connector and extending the service life of the connector.

[0042] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0043] This application discloses a connector 10, which is used in electrical equipment.
[0044] The connector 10 according to an embodiment of this application is described below with reference to Figures 1-5.
[0045] In some embodiments, as shown in Figures 1 and 2, the connector 10 includes: a fixed housing 11, a first conductor 12, a floating housing 17, a second conductor 13, and a flexible member 14.
[0046] The fixed housing 11 has a mounting structure 111 for mounting the connector 10 to the panel 20 of the electrical equipment; a first conductor 12 is disposed in the fixed housing 11 and is used for electrical connection with an external device; a floating housing 17 is slidably mounted on the fixed housing 11 along the axial direction of the fixed housing 11; a second conductor 13 is floatingly assembled on the fixed housing 11 and is used for electrical connection with the circuit board 30 of the electrical equipment; a flexible member 14 is disposed in the fixed housing 11 and is electrically connected between the first conductor 12 and the second conductor 13.
[0047] The fixed housing 11 serves as the main structure of the connector 10, and is used to install and protect key components such as the first conductor 12, the second conductor 13, and the flexible component 14 inside. The fixed housing 11 can be made of insulating materials, such as polyamide or polycarbonate, but this application embodiment does not limit this.
[0048] The mounting structure 111 designed on the fixed housing 11 may include, but is not limited to, nuts, threads, snaps or mounting holes, so as to securely install the connector 10 on the whole electrical equipment.
[0049] For example, as shown in FIG2, the mounting structure 111 may include external threads and nuts. The mating external threads and nuts on the fixed housing 11 allow the operator to tighten the nuts using a tool, thereby firmly fixing the entire fixed housing 11 to the panel 20 of the electrical equipment, so that the entire connector 10 stably passes through the panel 20 and extends into the interior to electrically connect with the circuit board 30 of the electrical equipment.
[0050] The first conductor 12 is the part of the connector 10 that is electrically connected to the external device. It can usually be designed as a needle, a sheet, or a column, etc., but this application embodiment does not limit this.
[0051] For example, in some embodiments, as shown in FIG4, the first conductor 12 is generally designed to be columnar.
[0052] The first conductor 12 can be installed in the fixed housing 11 by means of snap-fit, interference fit or key connection, etc., and the embodiments of this application do not limit this.
[0053] For example, in some embodiments, as shown in Figures 2 and 4, the first conductor 12 and the fixed housing 11 are snap-fitted together. Specifically, the first conductor 12 may be riveted with a plurality of circumferentially spaced claws, and the inner wall of the fixed housing 11 may be provided with corresponding slots for engaging with the plurality of claws.
[0054] The second conductor 13 is the part that electrically connects the connector 10 to the internal circuit board 30 of the electrical equipment. It can usually be designed as a needle, a sheet, or a column, etc., but this application embodiment does not limit it.
[0055] For example, in some embodiments, as shown in FIG4, the second conductor 13 is generally designed as a sheet.
[0056] The second conductor 13 is floated and assembled with the fixed housing 11 via a floating housing 17. The floating housing 17 can fix the second conductor 13 and the temperature sampling structure 15 by means of snaps, threads, or crimping, etc., which is not limited in this embodiment. The flexible element 14 is used to provide mechanical flexibility and electrical connection between the first conductor 12 and the second conductor 13. Specifically, the flexible element 14 can be a soft wire, a flexible circuit board, conductive rubber, conductive fabric, or other conductive materials with flexibility, which is not limited in this embodiment.
[0057] For example, in some embodiments, as shown in Figures 2 and 4, the flexible element 14 is a soft wire.
[0058] The connection method between the flexible element 14 and the first conductor 12 and the second conductor 13 may include, but is not limited to, welding, crimping or bolting, etc., and the embodiments of this application do not limit this.
[0059] In related technologies, some connectors use elastic elements such as metal springs to connect the first and second conductors, or connect flexible wires to the conductor ends of the connector, in order to compensate for positional errors between the panel and the circuit board of the electrical equipment. However, the use of elastic elements such as metal springs has the following drawbacks: First, during the deformation process, due to their material properties and structural characteristics, elastic elements such as metal springs inevitably generate mechanical stress. With the increase of usage time and the number of deformations, fatigue damage may occur in the elastic elements, thereby affecting their elastic performance and connection stability. Second, elastic elements such as metal springs essentially rely on the elastic deformation of metal materials to achieve positional compensation. However, the elastic characteristics of metal materials determine that their deformation range is relatively limited. When faced with large positional errors, the metal springs may not be able to provide sufficient displacement compensation, causing the connector to be unable to effectively adapt to the positional deviation between the circuit board and the panel, thereby affecting the stability of the electrical connection. Using the tail-end access flexible wire method requires a large amount of cable, which increases material costs. The assembly process is extremely complicated, requiring operators to have high operating skills. Moreover, the assembly process is time-consuming and labor-intensive, which greatly increases production time and labor costs. In addition, when many flexible wires are wired inside the machine, a lot of space must be reserved to meet the bending radius requirements of the wires, which is not conducive to the miniaturization and compact design of electrical equipment.
[0060] In actual operation, as shown in Figure 2, when the mounting structure 111 against the panel 20 is tightened, since the second conductor 13 is fixed to the circuit board 30, the spatial position of the floating housing 17 will not change significantly when the operator tightens the mounting structure 111. However, the fixed housing 11, which is slidably connected to the floating housing 17, will slide relative to the floating housing 17. That is, under the action of the tightening force, the fixed housing 11 slides outward relative to the floating housing 17, thereby causing the first conductor 12 fixed in the fixed housing 11 to also slide outward. The flexible member 14 between the first conductor 12 and the second conductor 13 will be straightened. Due to the flexibility of the flexible member 14 itself, the movement of the first conductor 12 and the fixed housing 11 during the installation of the connector 10 will not generate stress, nor will it cause additional stress to the first conductor 12 and the second conductor 13. This ensures that the internal electrical connection structure of the connector 10 is always in a stable stress environment throughout the entire use process, which greatly improves the reliability of the connector 10 and maintains the normal service life of the connector 10. During the floating process, the flexible element 14 can freely extend or bend as the relative positions of the first conductor 12 and the second conductor 13 change, achieving a large range of axial and radial floating, and its floating range far exceeds the adjustable range of general elastic elements.
[0061] For example, in some embodiments, taking the flexible element 14 as a soft wire, the first conductor 12 can meet the axial floating capability of 4mm by relying on the flexibility of the soft wire.
[0062] The connector 10 provided in this application embodiment, through the arrangement of the first conductor 12, the second conductor 13 and the flexible member 14, can effectively compensate for the positional error between the panel 20 and the circuit board 30 of the electrical equipment. It eliminates the need for a soft wire to be connected to the tail end of the connector 10, realizing the direct connection between the second conductor 13 and the circuit board 30, which significantly simplifies the installation process. At the same time, it reduces the number of wires required for the entire electrical equipment. The electrical equipment no longer needs to reserve a large space to meet the bending radius requirements of numerous wires, thereby reducing material and labor costs and realizing the miniaturization and compact design of the electrical equipment. In addition, compared with the use of elastic members such as metal springs for tolerance, the flexible member 14 will not cause additional stress to the first conductor 12 and the second conductor 13, and can achieve a wider range of floating, thereby greatly improving the reliability and stability of the connector 10 and extending the service life of the connector 10.
[0063] In some embodiments, as shown in Figures 2 and 4, the first conductor 12 and the fixed housing 11 are coaxially arranged, the first conductor 12 and the second conductor 13 are staggered in both the axial and radial directions of the fixed housing 11, and the flexible member 14 is arranged between the first conductor 12 and the second conductor 13 with a configuration having at least one bent portion.
[0064] The specific configuration of the flexible component 14 can be, but is not limited to, multi-layered spiral nesting, wave-like curling, or petal-like curling, and this application does not impose any restrictions on it.
[0065] The first conductor 12 is designed to be coaxial with the fixed housing 11. In other words, the central axis of the first conductor 12 coincides with or substantially coincides with the central axis of the fixed housing 11. This design makes the connector 10 more compact in structure and easier to plug into external devices.
[0066] As can be understood, as shown in Figures 2 and 4, the first conductor 12 and the second conductor 13 are staggered in the axial direction of the fixed housing 11. Specifically, the first conductor 12 is positioned near one end of the fixed housing 11, while the second conductor 13 is positioned near the other end, meaning the first conductor 12 and the second conductor 13 are spaced apart along the axial direction of the fixed housing 11. Furthermore, the first conductor 12 and the second conductor 13 are also staggered in the radial direction of the fixed housing 11. Specifically, the first conductor 12 can be positioned near the central axis of the fixed housing 11, while the second conductor 13 is positioned eccentrically, meaning the first conductor 12 and the second conductor 13 are spaced apart radially along the fixed housing 11. In this case, combined with the coiled design of the flexible component 14, on the one hand, a larger coiled storage space is provided between the first conductor 12 and the second conductor 13 for the flexible component 14, increasing the maximum length of the flexible component 14 and further enhancing the floating capability of the connector 10; on the other hand, it allows the flexible component 14 to be effectively distributed within a limited space, improving the space utilization rate of the connector 10.
[0067] In some embodiments, as shown in Figures 2 and 3, the connector 10 further includes a temperature sampling structure 15.
[0068] Temperature sampling structure 15 is installed on floating housing 17 and is used to collect the temperature of second conductor 13.
[0069] The temperature sampling structure 15 is electrically connected to the circuit board 30 of the electrical equipment. The temperature sampling structure 15 includes at least a temperature sensor for measuring temperature and an output pin for transmitting the collected temperature signal to the circuit board 30. The temperature sensor can be, but is not limited to, a thermistor, a thermocouple, or an RTD (Resistance Temperature Detector). The connection method between the output pin and the circuit board 30 can be, but is not limited to, soldering, plugging, or crimping. This application embodiment does not limit this.
[0070] In related technologies, to detect the conductor temperature of a connector during operation, a temperature sampling structure is typically soldered separately onto the circuit board, and then the connector conductor and the temperature sampling structure are connected by a thermally conductive component (such as a thermally conductive copper busbar). However, in practical applications, the above structure suffers from significant heat loss and interference during heat transfer, resulting in low accuracy of the data collected by the temperature sampling structure. Furthermore, it requires additional space and soldering points for the temperature sampling structure, increasing assembly complexity and cost.
[0071] Understandably, since the temperature sampling structure 15 and the second conductor 13 are mounted on the floating housing 17, the temperature sampling structure 15 can directly contact or indirectly transfer heat with the second conductor 13 at close range. This effectively solves the problems of thermal resistance and signal delay caused by heat-conducting components in traditional solutions, reduces heat loss and interference during heat transfer, and allows the temperature sampling structure 15 to more directly and accurately sense the temperature change of the second conductor 13, thereby achieving accurate and timely acquisition of the temperature of the second conductor 13. Furthermore, there is no need to reserve additional space and soldering points for the temperature sampling structure 15, simplifying the assembly process of electrical equipment and reducing assembly complexity and costs.
[0072] The connector 10 provided in this application embodiment integrates the temperature sampling structure 15 into the connector 10 as described above, which reduces the loss and interference in the heat transfer process, thereby achieving accurate and timely acquisition of the temperature of the second conductor 13, and simplifies the assembly process of electrical equipment, thereby reducing assembly complexity and assembly cost.
[0073] In some embodiments, as shown in FIG3, the floating housing 17 defines a first cavity 171 and a second cavity 172 separated by an insulating wall 173, a second conductor 13 is partially mounted in the first cavity 171, and a temperature sampling structure 15 is partially mounted in the second cavity 172.
[0074] The insulating wall 173 can be made of a high-insulation-performance material, such as polycarbonate, polyphenylene sulfide, or ceramics, and the embodiments of this application do not limit this.
[0075] In actual operation, in high-voltage and high-frequency electrical equipment, the second conductor 13 carries high voltage. If there is no good electrical isolation between it and the temperature sampling structure 15, leakage will not only affect the normal operation of the temperature sampling structure 15, but may also cause serious safety accidents. At the same time, the high-frequency strong electrical signal transmitted by the second conductor 13 may generate a strong electromagnetic field in the surrounding space. If the temperature sampling structure 15 and the second conductor 13 are in the same space, they are easily interfered with, resulting in inaccurate temperature measurement. This embodiment of the application separates the first cavity 171 and the second cavity 172 by introducing an insulating wall 173 inside the floating housing 17. This effectively reduces the risk of high voltage leakage from the second conductor 13 to the area where the temperature sampling structure 15 is located, significantly alleviates strong and weak current coupling interference caused by leakage, enhances the electrical insulation performance of the connector 10, thereby improving the reliability of the connector 10 and thus the reliability of the entire electrical equipment. At the same time, it reduces the electromagnetic interference generated by strong electrical signals through conduction or radiation to the temperature sampling structure 15, enabling the temperature sampling structure 15 to be in a relatively independent electromagnetic environment, accurately collect the temperature data of the second conductor 13, and provide a reliable basis for the stable operation of the electrical equipment.
[0076] It should be noted that the wall thickness design of the insulating wall 173 needs to take into account both the insulation effect and the heat transfer effect, and can be customized according to the actual situation. This application embodiment does not limit this.
[0077] The connector 10 provided in this application embodiment, through the above-described structural design of introducing an insulating wall 173 within the floating housing 17 to form independent first cavity 171 and second cavity 172, effectively reduces the risk of high voltage leakage from the second conductor 13 to the area where the temperature sampling structure 15 is located, significantly alleviates strong and weak current coupling interference caused by leakage, thereby improving the reliability of the connector 10, and further improving the reliability of the entire electrical equipment. At the same time, it reduces electromagnetic interference generated by strong electrical signals through conduction or radiation to the temperature sampling structure 15, further improving the accuracy of temperature sampling and maintaining the stable operation of the electrical equipment.
[0078] In some embodiments, as shown in FIG3, the insulating wall 173 is part of the floating housing 17.
[0079] In this embodiment, as shown in FIG3, the insulating wall 173 is integrally formed with the other parts of the floating shell 17. Specifically, the floating shell 17 can be manufactured by integral molding processes such as injection molding, die casting, and 3D printing, directly forming the first cavity and the second cavity separated by the insulating wall 173 during the molding process. For example, by using plastic injection molding, the insulating wall 173 and the other parts of the floating shell 17 are made of the same material, resulting in good integration and a relatively simple manufacturing process.
[0080] In other embodiments, the insulating wall 173 and the floating shell 17 may also be separate structures, that is, the insulating wall 173 is fixed in the floating shell 17 by means of bonding, interference fit or snap-fit.
[0081] The connector 10 provided in this application embodiment, through the above-described structural design in which the insulating wall 173 is part of the floating shell 17, allows the insulating wall 173 to be seamlessly connected to other parts of the floating shell 17 without seams or gaps, thereby enhancing the overall mechanical strength. During use, the floating shell 17 with the integrated insulating wall 173 can withstand greater external impacts and vibrations, and is less prone to deformation or damage, thereby improving the reliability of the connector.
[0082] In some embodiments, as shown in FIG3, at least a portion of the temperature sampling structure 15 is covered with an insulating encapsulation layer 16.
[0083] In this embodiment, the temperature sensor of the temperature sampling structure 15 is entirely covered by an insulating encapsulation layer 16, while the output pins of the temperature sampling structure 15 are not covered by the insulating encapsulation layer 16.
[0084] In other embodiments, the temperature sensor of the temperature sampling structure 15 is entirely covered by an insulating encapsulation layer 16, and a local area of the output pin of the temperature sampling structure 15 is covered by the insulating encapsulation layer 16.
[0085] The insulating encapsulation layer 16 can be made of polymer materials, such as epoxy resin, polyimide or silicone, and the encapsulation process can be carried out by impregnation, spraying, dripping or molding, etc. The embodiments of this application do not limit this.
[0086] The connector 10 provided in this application embodiment, through the above-described structural design of covering the temperature sampling structure 15 with an insulating encapsulation layer 16, provides secondary protection for the temperature sampling structure 15 itself, based on the aforementioned insulating wall 173 blocking most of the strong electrical interference from the second conductor 13. This reduces the negative impact of possible minor electrical leakage or induced current on the temperature sampling structure 15, further enhancing the electrical isolation effect on the temperature sampling structure 15. This further improves the accuracy of temperature sampling and enhances the electrical safety and reliability of the connector 10 in high-voltage environments. In addition, the insulating encapsulation layer 16 also provides mechanical protection, reducing physical damage to the temperature sampling structure 15 during transportation, installation, and use.
[0087] In some embodiments, as shown in FIG3, the insulating encapsulation layer 16 is made of a soft material and is filled between the temperature sampling structure 15 and the wall of the second cavity 172.
[0088] In other words, the insulating encapsulation layer 16 needs to be made of a soft insulating material, such as epoxy resin, silicone, polyurethane foam or thermoplastic elastomer, etc., and this application embodiment does not limit this.
[0089] Understandably, since the insulating encapsulation layer 16 is made of soft material and is filled between the temperature sampling structure 15 and the wall of the second cavity 172, the insulating encapsulation layer 16, in addition to providing the original electrical isolation, can also form strong friction and constraint forces at the contact surfaces with the temperature sampling structure 15 and the wall of the second cavity 172. This can effectively limit the displacement and shaking of the temperature sampling structure 15 within the floating shell 17. During the operation of the electrical equipment, even if subjected to external forces such as vibration and impact, the temperature sampling structure 15 can remain stable, ensuring reliable acquisition of temperature data, thereby improving the accuracy of temperature monitoring and maintaining the normal operation of the equipment.
[0090] The connector 10 provided in this application embodiment, through the structural design of the soft insulating encapsulation layer 16 filling the space between the temperature sampling structure 15 and the wall of the second cavity 172, not only performs the original electrical insulation function of the insulating encapsulation layer 16, but also achieves the function of fixing the position of the temperature sampling structure 15 in the floating housing 17. The soft insulating encapsulation layer 16 can closely fit the walls of the temperature sampling structure 15 and the second cavity 172, effectively reducing the displacement and shaking of the temperature sampling structure 15 in the floating housing 17, thereby improving the stability and reliability of the connector 10.
[0091] In some embodiments, as shown in Figures 3-5, the second conductor 13 is provided with a first limiting structure 131 and a second limiting structure 132, and the floating shell 17 is provided with a third limiting structure 174 and a fourth limiting structure 175. The first limiting structure 131 and the third limiting structure 174 cooperate to restrict the movement of the second conductor 13 toward the first conductor 12, and the second limiting structure 132 and the fourth limiting structure 175 cooperate to restrict the movement of the second conductor 13 toward the direction away from the first conductor 12.
[0092] The limiting engagement form of the first limiting structure 131 and the third limiting structure 174 may include, but is not limited to, a protruding groove type limiting or a snap-on slot type limiting, etc. The limiting engagement form of the second limiting structure 132 and the fourth limiting structure 175 may include, but is not limited to, a protruding groove type limiting or a snap-on slot type limiting, etc. The embodiments of this application do not limit this.
[0093] For example, as shown in Figures 3-5, the second conductor 13 is designed as a sheet, and the normal of the large surface of the sheet-shaped second conductor 13 can be perpendicular to the axial direction of the fixed housing 11. The first limiting structure 131 can be provided on at least one side of the second conductor 13 along the thickness direction. For example, the first limiting structure 131 can be provided on the side of the second conductor 13 along the thickness direction and away from the temperature sampling structure 15. The first limiting structure 131 can be a limiting protrusion. The third limiting structure 174 can be a limiting groove for cooperating with the limiting protrusion. The second limiting structure 132 can be provided on at least one side of the second conductor 13 along the width direction. For example, the second limiting structure 132 can be provided on both sides of the second conductor 13 along the width direction. The second limiting structure 132 can be a limiting protrusion. The fourth limiting structure 175 can be a limiting groove for cooperating with the limiting protrusion.
[0094] The connector 10 provided in this application embodiment, through the setting of the first limiting structure 131, the second limiting structure 132, the third limiting structure 174 and the fourth limiting structure 175, realizes the bilateral limiting of the second conductor 13 within the floating housing 17 along the axial direction of the fixed housing 11. On the one hand, it can accurately control the position of the second conductor 13 within the floating housing 17, reduce installation errors and improve the assembly accuracy of the connector 10. On the other hand, it can minimize the displacement or shaking of the second conductor 13 within the floating housing 17, thereby significantly reducing the risk of the second conductor 13 loosening and falling off, and thus improving the stability and reliability of the connector 10.
[0095] In some embodiments, the flexible member 14 is welded to the first conductor 12 and the second conductor 13, and the circuit board 30 is welded to the second conductor 13.
[0096] The specific welding process between the flexible component 14 and the first conductor 12 and the second conductor 13 can be, but is not limited to, resistance welding, laser welding or reflow welding, etc., and the embodiments of this application do not limit this.
[0097] For example, in some embodiments, the flexible element 14 is connected to the first conductor 12 and the second conductor 13 by resistance welding.
[0098] The specific welding process between the circuit board 30 and the second conductor 13 can be, but is not limited to, wave soldering, laser soldering, or reflow soldering, etc., and this application embodiment does not limit this.
[0099] For example, in some embodiments, wave soldering is used between the circuit board 30 and the second conductor 13.
[0100] Understandably, by welding the flexible component 14 to the first conductor 12 and the second conductor 13, and welding the circuit board 30 to the second conductor 13, on the one hand, the complex external flexible wire system in the traditional connection method is eliminated, which can reduce the procurement, storage and installation costs of a large number of flexible wires. At the same time, since there is no need for external flexible wires, the internal wiring of electrical equipment is simpler, reducing the potential for faults caused by complex wiring and reducing maintenance costs. On the other hand, in the traditional connection method, external flexible wires need to undergo a series of complex operations such as stripping, twisting and crimping, while welding connection only requires accurately placing each component in the welding position and then welding. The connector 10 using welding connection can reduce operation steps, improve production efficiency and reduce labor costs. Furthermore, welding connection can achieve low resistance and stable connection between connected objects. Compared with external flexible wires, the electrical contact of the welding point is more reliable, which can effectively reduce problems such as increased resistance, overheating or even open circuit caused by poor contact. In addition, welding connection allows the second conductor 13 to be directly connected to the circuit board 30, reducing the interference that may be introduced by external flexible wires and improving the stability of electrical signal transmission.
[0101] This application also discloses an electrical device.
[0102] In some embodiments, as shown in Figures 1 and 2, the electrical device includes: a panel 20, a circuit board 30, and a connector 10 as described in any of the above embodiments.
[0103] The connector 10 is mounted on the panel 20 via the mounting structure 111, and the second conductor 13 and the temperature sampling structure 15 of the connector 10 are electrically connected to the circuit board 30.
[0104] It should be noted that panel 20 is part of the housing of electrical equipment, circuit board 30 is located inside the housing of electrical equipment, and connector 10 can pass through panel 20. In this way, part of connector 10 can extend into the housing and be electrically connected to circuit board 30, and the other part of connector 10 can be exposed outside the housing and be electrically connected to external equipment.
[0105] Electrical equipment can be power conversion devices, including but not limited to inverters, transformers, rectifiers, or DC-DC converters, etc., and the embodiments of this application do not limit this.
[0106] The electrical equipment provided in this application embodiment, through the aforementioned connector 10, allows the flexible component 14 to effectively compensate for the positional error between the panel 20 and the circuit board 30. It eliminates the need for a soft wire to be connected to the end of the connector 10, enabling direct connection between the second conductor 13 and the circuit board 30. This significantly simplifies the installation process and reduces the number of wires required for the entire electrical equipment. Furthermore, the internal space of the electrical equipment no longer needs to accommodate the bending radius requirements of numerous wires, thereby reducing material and labor costs. It also achieves miniaturization and compact design of the electrical equipment. Moreover, compared to using elastic components such as metal springs for tolerance, the flexible component 14 does not cause additional stress to the first conductor 12 and the second conductor 13, and can achieve a wider range of floating, thus greatly improving the reliability and stability of the connector 10 and extending its service life.
