[0058] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0059] In the description of this application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0061] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0062] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0063] To improve vehicle range, an increasing number of vehicles are adopting 48V power supply systems to replace traditional 12V systems. This shift is primarily based on the advantages of 48V power supply systems in power transmission efficiency and system design. Firstly, 48V power supply systems can significantly reduce current intensity for the same power output, thereby reducing power loss in the power supply system. Since power loss is proportional to the square of the current, reducing current can significantly reduce energy loss, which is crucial for extending vehicle range. Secondly, the application of 48V power supply systems helps reduce the weight of wiring harnesses inside the vehicle. In traditional 12V systems, thicker wires are needed to meet higher current demands, which not only increases the overall weight of the vehicle but also occupies more space. In 48V systems, due to the increased voltage, the current required for the same power output is significantly reduced, allowing the use of thinner wires, effectively reducing wiring harness weight and optimizing vehicle design. However, compared to 12V power supply systems, 48V power supply systems also face some challenges in practical applications. Especially inside low-voltage connectors, conductive components in 48V power supply systems are more prone to electrical breakdown and creepage. This phenomenon mainly occurs because the increased voltage leads to an increased electric field strength, making it easier for arcing or surface discharge to occur between conductive components inside the connector or between conductive components and insulating materials. These phenomena can cause electrical breakdown or creepage in the conductive components inside the low-voltage connector, increasing the probability of power supply system failure and potentially even causing safety issues. How to solve these problems has become a pressing challenge for those skilled in the art. To address these issues, this application provides an insulating component, an electrical connector with the insulating component, and a vehicle with the electrical connector.

[0064] Please see Figure 1 The insulating component 10 of the electrical connector 100 in this embodiment includes an insulating pad 11. The insulating pad 11 includes a first insulating surface 111 and a second insulating surface 112 facing each other. The second insulating surface is adapted to be disposed facing the circuit board. The insulating pad 11 also includes a clearance hole 113 and an insulating member 114. The clearance hole 113 connects the first insulating surface 111 and the second insulating surface 112. The clearance hole 113 is used to pass through a conductive component. The insulating member 114 is disposed at least on the second insulating surface 112 and between adjacent clearance holes 113.

[0065] Electrical connector 100, commonly referred to as a power connector or electrical connector, is a device used to form a separable electrical connection. Its main function is to provide a reliable conductive path between two or more electrical components, allowing current to flow between the devices. Electrical connector 100 typically consists of two mating parts; one part is mounted at one end of a circuit, and the other part can be inserted into or connected to this part to form a complete circuit. Insulating component 10 is the core protective structure in electrical connector 100 used to prevent electrical breakdown and creepage. Insulating component 10 includes insulating pad 11, which is a core component for isolating the conductive pads 22 of circuit board 20 and is made of insulating material.

[0066] Specifically, the insulating pad 11 in this application includes a first insulating surface 111 and a second insulating surface 112 disposed opposite to each other. The first insulating surface 111 and the second insulating surface 112 are two opposing surfaces of the insulating pad 11, located at the top and bottom of the insulating pad 11, respectively (specifically, the first insulating surface 111 can be either the top or bottom of the insulating pad 11, and the second insulating surface 112 is the other surface opposite to the first insulating surface 111). Both the first insulating surface 111 and the second insulating surface 112 have insulating properties. For example, the first insulating surface 111 typically faces the circuit board 20 or other conductive components, and can be used to directly isolate the pads 22 or conductive components. The second insulating surface 112 faces the external environment or associated components (such as the insulating cover 12) to form a protective barrier for the conductive components. The first insulating surface 111 and the second insulating surface 112 together ensure that current cannot leak laterally through the surface of the insulating pad 11 (i.e., prevent creepage).

[0067] Furthermore, the insulating pad 11 also includes clearance holes 113 and insulating elements 114. The clearance hole 113 is a perforated structure penetrating the insulating pad 11, with its two openings connecting to the first insulating surface 111 and the second insulating surface 112, respectively. The clearance hole 113 is used to pass through conductive components (such as terminals, wires, or pad 22 pins) to achieve electrical connection between the conductive components (such as terminals, wires, or pad 22 pins) and the circuit board 20. An insulating gap is maintained between the inner wall of the clearance hole 113 and the conductive components to prevent electrical breakdown of the conductive components under high voltage. The insulating element 114 is disposed on the second insulating surface 112 and between adjacent clearance holes 113. The insulating element 114 is an isolation structure disposed between the insulating surfaces, located between adjacent clearance holes 113. The insulating element 114 increases the creepage distance between conductive components by physically separating adjacent clearance holes 113 (i.e. adjacent conductive components). In this application, the insulating element 114 is designed as a raised rib-like or wall-like structure (e.g., the first insulating rib 1121 below). The height and width of the insulating element 114 can be set by relevant personnel according to the safety standards of the 48V system.

[0068] It is understood that this application provides an insulating component 10, which includes an insulating pad 11. The insulating pad 11 includes a first insulating surface 111 and a second insulating surface 112 facing each other. The insulating pad 11 also includes clearance holes 113 and insulating elements 114. The openings of the clearance holes 113 are respectively connected to the first insulating surface 111 and the second insulating surface 112, so that conductive components can pass through the clearance holes 113 to pass through the insulating pad 11, ensuring the normal installation of the conductive components. The insulating elements 114 are disposed on the second insulating surface 112 and between adjacent clearance holes 113, so as to independently isolate the conductive components passing through the insulating pad 11, thereby avoiding electrical breakdown and creepage phenomena of the conductive components during use.

[0069] In some implementations, please refer to Figure 1 The insulating element 114 is also disposed on the first insulating surface 111.

[0070] It is understood that the insulating element 114 can also be disposed on the first insulating surface 111 and between adjacent clearance holes 113. In this case, the insulating element 114 is disposed on both the first insulating surface 111 and the second insulating surface 112. The insulating element 114 is an isolation structure disposed between the insulating surfaces and is located between adjacent clearance holes 113. The insulating element 114 on the first insulating surface 111 and the second insulating surface 112 forcibly increases the creepage distance between conductive components by physically separating adjacent clearance holes 113 (i.e., adjacent conductive components). In this application, the insulating element 114 is designed as a raised rib-like or wall-like structure (e.g., the first insulating rib 1121 hereinafter). The height and width of the insulating element 114 can be set by relevant personnel according to the safety standards of the 48V system.

[0071] In some implementations, please refer to Figure 1 The insulating element 114 includes a first insulating rib 1121 protruding from the second insulating surface 112.

[0072] Specifically, the insulating element 114 includes a first insulating rib 1121 protruding from the second insulating surface 112. The first insulating rib 1121 itself is an insulating object. When conductive components or the like pass through the clearance hole 113, the first insulating rib 1121 can increase the creepage distance on the surface of the insulating pad 11, thereby avoiding electrical breakdown.

[0073] In some implementations, please refer to Figure 2 and Figure 3 The insulating assembly 10 also includes an insulating cover 12. An insulating pad receiving groove 1211 is provided on the third insulating surface 121 of the insulating cover 12. The insulating pad receiving groove 1211 is used to receive the insulating pad 11, with the first insulating surface 111 facing the insulating cover 12. A first through hole 12111 is provided at the bottom of the insulating pad receiving groove 1211. The projection of the first through hole 12111 on the third insulating surface 121 coincides with the projection of the clearance hole 113 on the third insulating surface 121.

[0074] Specifically, the insulating assembly 10 also includes an insulating cover 12, which is a protective structure covering the insulating pad 11. The insulating cover 12 can be connected to the insulating pad 11 via a snap-fit ​​structure 1212 (which will be explained in detail below) to form a double insulating barrier for conductive components such as terminals, wires or pad 22 pins.

[0075] More specifically, the insulating cover 12 has a third insulating surface 121, which is the surface of the insulating cover 12 that contacts the insulating pad 11. The third insulating surface 121 has insulating properties and is used to form a physical fit with the insulating pad 11. An insulating pad receiving groove 1211 is provided on the third insulating surface 121. The insulating pad receiving groove 1211 is a groove structure located on the third insulating surface 121 of the insulating cover 12, which can be used to accommodate and fix the insulating pad 11. The insulating pad 11, through the insulating pad receiving groove 1211 designed on the surface of the third insulating surface 121, can prevent the insulating pad 11 from shifting during installation. The shape of the groove 1211 is consistent with the outer contour of the insulating pad 11, thereby preventing misalignment during assembly that could lead to insulation failure.

[0076] More specifically, the bottom of the insulating pad receiving groove 1211 is provided with a first through hole 12111, which ensures that the conductive components can penetrate the insulating cover 12 and the clearance hole 113 of the insulating pad 11 to complete the electrical connection.

[0077] In some implementations, please refer to Figure 1 and Figure 2 The first insulating surface 111 is provided with a first protrusion 1111, and the bottom of the insulating pad receiving groove 1211 is provided with a first mating part 12112. The first protrusion 1111 is used to connect the first mating part 12112.

[0078] Specifically, the first insulating surface 111 of the insulating pad 11 is provided with a first protrusion 1111. The first protrusion 1111 is a raised structure located on the first insulating surface 111 of the insulating pad 11, and is used to form a physical connection with the first mating part 12112 of the insulating cover 12. During assembly, the first protrusion 1111 can be inserted into the first mating part 12112 of the insulating cover 12 to provide lateral restraint and prevent the insulating pad 11 from shifting or loosening in the receiving groove.

[0079] Specifically, the bottom of the insulating pad receiving groove 1211 is provided with a first mating part 12112. The first mating part 12112 is a groove or hole structure located at the bottom of the insulating pad receiving groove 1211 of the insulating cover 12, which is used to match and connect with the first protrusion 1111 of the insulating pad 11. The groove shape of the first mating part 12112 is complementary to the first protrusion 1111 (e.g., a circular groove corresponds to a cylindrical boss), thereby ensuring that the assembly direction is unique.

[0080] In some implementations, please refer to Figure 1 and Figure 2The insulating pad receiving groove 1211 has a first side 12113 and a second side 12114 with anti-mistake mating part 12115, and the insulating pad 11 has an anti-mistake protrusion 117 with a third side 115 and a fourth side 116 with a mistake mating part 117. The anti-mistake mating part 12115 is used to connect the anti-mistake protrusion 117.

[0081] Specifically, the first side 12113 and the second side 12114 of the insulating pad receiving groove 1211 are provided with a foolproof mating part 12115. The foolproof mating part 12115 is a groove or guide structure located on the first side 12113 and the second side 12114 of the insulating pad receiving groove 1211 of the insulating cover 12, and is used to match and connect with the foolproof protrusion 117 of the insulating pad 11. Since the foolproof protrusion 117 needs to be installed in conjunction with the foolproof mating part 12115, the insulating pad 11 can be installed into the insulating pad receiving groove 1211 in the correct shape. If the insulating pad 11 is installed into the insulating pad receiving groove 1211 in the wrong direction, the locking pin 1171 on the foolproof protrusion 117 cannot be aligned with the mating hole 12116 on the foolproof mating part 12115. Therefore, this foolproof design can be used to force the operator to install the insulating pad 11 in the correct direction and avoid human error.

[0082] In some implementations, please refer to Figure 1 , Figure 2 and Figure 3 The anti-foolproof protrusion 117 is provided with a locking pin 1171, and the bottom of the insulating pad receiving groove 1211 is provided with a mating hole 12116. When the insulating pad 11 is housed in the insulating pad receiving groove 1211, the locking pin 1171 is connected to the mating hole 12116.

[0083] For example, the first protrusion 1111 mentioned above can be a locking pin 1171, and the first mating part 12112 can be a mating hole 12116 (the mating hole 12116 is a hole structure located at the bottom of the insulating pad receiving groove 1211, the shape of the mating hole 12116 matches the locking pin 1171, and the mating hole 12116 is used to receive and fix the locking pin 1171). The foolproof protrusion 117 is provided with a locking pin 1171, which is a columnar or conical protrusion provided on the foolproof protrusion 117, used to form a physical lock with the mating hole 12116 at the bottom of the insulating pad receiving groove 1211. When the insulating pad 11 is inserted into the insulating pad receiving groove 1211, the locking pin 1171 can be inserted into the mating hole 12116 provided at the bottom of the insulating pad receiving groove 1211, thereby providing longitudinal fixation for the insulating pad 11 and preventing the insulating pad 11 from falling out under vibration or impact.

[0084] In some implementations, please refer to Figure 4 The insulating cover 12 has pressing handles 122 on opposite sides.

[0085] Specifically, the insulating cover 12 has pressing handles 122 on opposite sides. These pressing handles 122 are operable components located on both sides of the insulating cover 12, symmetrically distributed at opposite ends. During the installation of the electrical connector 100, personnel can apply external force to the pressing handles 122 to control the locking or unlocking of the latching structure 1212. For example, by pressing the pressing handles 122 on both sides, personnel can deform the latching structure 1212 (such as a pre-lock / final lock latch) of the insulating cover 12, thus fixing it in the final lock position. Personnel can also release the final lock by pressing in the opposite direction (if it is necessary to disassemble the electrical connector 100), facilitating the repair or adjustment of the electrical connector 100. This process will be explained in more detail below.

[0086] In some implementations, please refer to Figure 2 The side of the insulating pad receiving groove 1211 is provided with a second insulating rib 12117.

[0087] Specifically, the second insulating rib 12117 is a protruding structure provided on the side of the insulating pad receiving groove 1211 to prevent the insulating pad 11 from falling out of the insulating pad receiving groove 1211.

[0088] In summary, the insulating component 10 in this embodiment includes an insulating pad 11, which includes a first insulating surface 111 and a second insulating surface 112. The insulating pad 11 also includes clearance holes 113 and an insulating element 114. The openings of the clearance holes 113 are respectively connected to the first insulating surface 111 and the second insulating surface 112, allowing conductive components to pass through the clearance holes 113 and through the insulating pad 11, ensuring proper installation of the conductive components. The insulating element 114 is disposed on the first insulating surface 111 and the second insulating surface 112, and between adjacent clearance holes 113, to independently isolate the conductive components passing through the insulating pad 11, thereby preventing electrical breakdown and creepage during use.

[0089] In some implementations, please refer to Figure 5 and Figure 6 This application also provides an electrical connector 100. The electrical connector 100 includes a circuit board 20 and an insulating component 10 as described in any of the above embodiments. The number of insulating components 10 is at least two, and different insulating components 10 are connected to both sides of the circuit board 20.

[0090] Specifically, an electrical connector 100, often referred to as a power connector or electrical connector, is a device used to form a separable electrical connection. Its main function is to provide a reliable conductive path between two or more electrical components, allowing current to flow between the devices. An electrical connector 100 typically consists of two mating parts, one of which is mounted at one end of a circuit, and the other part can be inserted into or connected to this part to form a complete circuit.

[0091] Furthermore, the electrical connector 100 includes a circuit board 20 and an insulating component 10 as described in any of the above embodiments. The number of insulating components 10 is at least two, with different insulating components 10 connected to both sides of the circuit board 20. Since the conductive components need to pass through the circuit board 20, insulating components 10 are required on both sides of the circuit board 20 to prevent electrical breakdown and creepage between the conductive components on both sides of the circuit board 20.

[0092] In some implementations, please refer to Figure 7 The circuit board 20 has a second through hole 21 and a pad 22, with the pad 22 surrounding the opening of the second through hole 21. The projection of the second through hole 21 onto the third insulating surface 121 coincides with the projection of the first through hole 12111 onto the third insulating surface 121.

[0093] Specifically, the circuit board 20 has a second through-hole 21. The second through-hole 21 is a through-hole in the circuit board 20, and there are at least two of them. The second through-hole 21 is used to pass conductive components (such as conductive terminals 40, pins, etc.). The second through-hole 21 provides a fixing channel for the conductive components, ensuring precise soldering between the conductive components and the circuit board 20. The circuit board 20 also has pads 22, which are metallized areas surrounding the openings of the second through-holes 21. The pads 22 are used to solder conductive components (such as conductive terminals 40, pins, etc.). By soldering and fixing the conductive components, the pads 22 create a current conduction path between the conductive components and the circuit board 20.

[0094] In some implementations, please refer to Figure 4 and Figure 8 The third insulating surface 121 is provided with a snap-fit ​​structure 1212, and the insulating cover 12 is fixed in a pre-locked position or a final-locked position by the snap-fit ​​structure 1212. In the pre-locked position, the snap-fit ​​structure 1212 is fixed to the circuit board 20 to provide an isolation space between the insulating component 10 and the circuit board 20. In the final-locked position, the snap-fit ​​structure 1212 is fixed to another insulating cover 12 on the opposite side of the circuit board 20 to ensure that the circuit board 20 and the insulating component 10 are in close contact.

[0095] Specifically, a snap-fit ​​structure 1212 is provided on the third insulating surface 121. The snap-fit ​​structure 1212 is a fixing device located on the third insulating surface 121 of the insulating cover 12. The snap-fit ​​structure 1212 consists of a first snap 12121, a second snap 12122, and a third snap 12123, and is used to fix the insulating cover 12 in a pre-locked position or a final-locked position. The pre-locked position refers to the position where the insulating cover 12 is initially fixed. In this state, the operator can perform operations such as solder joint inspection. The final-locked position refers to the position where the insulating cover 12 is finally fixed. In this state, the operator cannot perform operations such as solder joint inspection. The insulating component 10 forms a sealed insulating barrier to protect the conductive component and prevent electrical breakdown or creepage of the conductive component.

[0096] In some implementations, please refer to Figure 4 and Figure 8 The snap-fit ​​structure 1212 includes a first snap-fit ​​12121, and the circuit board 20 has a snap-fit ​​hole 23. The first snap-fit ​​12121 passes through the snap-fit ​​hole 23.

[0099] Specifically, the first buckle 12121 is the main fixing buckle located on the third insulating surface 121. There are at least two first buckles 12121. The first buckles 12121 are arranged diagonally on the third insulating surface 121. The diagonal arrangement of the first buckles 12121 can provide a symmetrical stress distribution and prevent the insulating cover 12 from tilting due to force on one side.

[0100] In some implementations, please refer to Figure 4 and Figure 8The first latch 12121 includes a first latch arm 121211 and a first locking part 121212. The first latch arm 121211 is located on the side of the first locking part 121212 near the third insulating surface 121, and the first latch arm 121211 and the first locking part 121212 are integrally connected. When the insulating cover 12 is fixed in the pre-locked position, the first latch arm 121211 passes through the latch hole 23, and the bottom surface of the first locking part 121212 abuts against the surface of the circuit board 20.

[0101] Specifically, the first latch 12121 includes a first latch arm 121211 and a first locking portion 121212. The first latch arm 121211 is an elastically deformable component on the first latch 12121, located between the first locking portion 121212 and the third insulating surface 121, for passing through the latch hole 23 and transmitting locking force to the insulating cover 12. The first locking portion 121212 is the end structure of the first latch 12121, integrally formed with the first latch arm 121211, and can be used to limit the longitudinal displacement of the insulating cover 12. When the insulating cover 12 is fixed in the pre-locked position, the first latch arm 121211 passes through the latch hole 23, and the bottom surface of the first locking portion 121212 abuts against the surface of the circuit board 20.

[0102] In some implementations, please refer to Figure 4 and Figure 8 The buckle structure 1212 also includes a second buckle 12122 and a third buckle 12123. The circuit board 20 is provided with a buckle hole 23. The second buckle 12122 and the third buckle 12123 are both inserted through the buckle hole 23. The second buckle 12122 is connected to the third buckle 12123 of the other insulating cover 12 on the opposite side of the circuit board 20, and the third buckle 12123 is connected to the second buckle 12122 of the other insulating cover 12 on the opposite side of the circuit board 20.

[0103] Specifically, a snap-fit ​​structure 1212 is provided on the third insulating surface 121. The snap-fit ​​structure 1212 is a fixing device located on the third insulating surface 121 of the insulating cover 12. The snap-fit ​​structure 1212 consists of a second snap 12122 and a third snap 12123, used to fix the insulating cover 12 in a pre-locked position or a final-locked position. The pre-locked position refers to the position where the insulating cover 12 is initially fixed. In this state, the operator can perform operations such as solder joint inspection. The final-locked position refers to the position where the insulating cover 12 is finally fixed. In this state, the operator cannot perform operations such as solder joint inspection. The insulating component 10 forms a sealed insulating barrier to protect the conductive component and prevent electrical breakdown or creepage. The snap-fit ​​hole 23 is a hole on the circuit board 20 for the snap-fit ​​structure 1212 to pass through. The snap-fit ​​hole 23 can cooperate with the second snap 12122 and the third snap 12123 to jointly fix the insulating component 10. The snap-fit ​​structure 1212 will be explained in more detail below.

[0104] In some implementations, please refer to Figure 4 and Figure 8 The number of second buckles 12122 is at least two, and the second buckles 12122 are arranged diagonally opposite each other. The number of third buckles 12123 is at least two, and the third buckles 12123 are arranged diagonally opposite each other.

[0105] Specifically, the second latch 12122 is an auxiliary latch located on the third insulating surface 121. There are at least two second latches 12122, arranged diagonally opposite each other. The second latches 12122 are used to interlock with the third latches 12123 of other insulating covers 12 to prevent the insulating assembly 10 from loosening due to vibration. The third latch 12123 is also an auxiliary latch located on the third insulating surface 121. There are at least two third latches 12123, arranged diagonally opposite each other. The third latches 12123 are used to interlock with the second latches 12122 of other insulating covers 12 to prevent the insulating assembly 10 from loosening due to vibration. The diagonal arrangement of the first latches 12121, second latches 12122, and third latches 12123 ensures even distribution of assembly pressure, thereby preventing overload damage to one side of the electrical connector 100 during use.

[0106] In some implementations, please refer to Figure 4 and Figure 8The second latch 12122 includes a second latch arm 121221 and a second locking portion 121222. The second latch arm 121221 is located on the side of the second locking portion 121222 near the third insulating surface 121, and the second latch arm 121221 and the second locking portion 121222 are integrally connected. When the insulating cover 12 is fixed in the pre-locked position, the second locking portion 121222 is connected to the third latch 12123. The second locking portion 121222 also has a pre-locking locking surface 121223, and the third latch 12123 also has a pre-locking mating surface 121231. The pre-locking locking surface 121223 is used to abut against the pre-locking mating surface 121231.

[0107] Specifically, the second latch 12122 includes a second latch arm 121221 and a second locking portion 121222. The second latch arm 121221 is an elastically deformable component on the second latch 12122. The second latch arm 121221 is located between the second locking portion 121222 and the third insulating surface 121 for engaging with the third latch 12123 to form an interlocking mechanism. The second locking portion 121222 is the end structure of the second latch 12122. The second locking portion 121222 is integrally formed with the second latch arm 121221 for engaging with the third latch 12123 to form an interlocking engagement.

[0108] Furthermore, when the insulating cover 12 is fixed in the pre-locked position, the second locking part 121222 is connected to the third buckle 12123. The second locking part 121222 also has a pre-locking locking surface 121223, and the third buckle 12123 also has a pre-locking mating surface 121231. The pre-locking locking surface 121223 is used to abut against the pre-locking mating surface 121231.

[0109] In some implementations, please refer to Figure 3 , Figure 8 and Figure 9 The insulating cover 12 also includes a snap-fit ​​groove 123, which contacts the third snap-fit ​​12123. When the insulating cover 12 is fixed in the final locked position, the second locking part 121222 is accommodated in the snap-fit ​​groove 123 of another insulating cover 12, and the two sides of the circuit board 20 respectively contact the third insulating surface 121 of the two different insulating covers 12.

[0110] Specifically, please combine Figure 10The latching groove 123 is a recessed structure used to accommodate the second locking part 121222 of another insulating cover 12, thus forming an interlocking mechanism. When the insulating cover 12 is in the pre-locked position on the circuit board 20, relevant personnel can solder the conductive components to the circuit board 20. After the soldering is completed, relevant personnel can check whether there are any problems with the soldering position. At this time, the pre-locking surface 121223 and the pre-locking mating surface 121231 are in contact with each other, and the side of the first locking part 121212 near the first latching arm 121211 (i.e., the bottom surface of the first locking part 121212) is in contact with the circuit board 20. The first latching arm 121211 passes through the latching hole 23.

[0111] Furthermore, please combine Figure 11 The operator can press the pressing handles 122 of the upper and lower insulating covers 12 respectively to change the insulating cover 12 from the pre-locked position to the final locked position. During the process of the insulating cover 12 entering the final locked position, the pre-locking locking surface 121223 is subjected to the interference force of the pre-locking mating surface 121231 on the third latch 12123 of the insulating cover 12 on the other side of the circuit board 20. The second latch arm 121221 deforms in the opposite direction of the interference, so that the second locking part 121222 can pass over the pre-locking mating surface 121231 and engage with the latch groove 123. At the same time as the engagement is completed, the third insulating surface 121 on the insulating cover 12 contacts the board surface of the circuit board 20. At this time, the insulating cover 12 remains in the final locked position.

[0112] Furthermore, please combine Figure 10 and Figure 11 When the insulating cover 12 is in the final locked position, the insulating cover 12 and the circuit board 20 clamp the insulating pad 11 in the middle. The insulating component 114 interferes with and is compressed against the insulating cover 12 and the circuit board 20, and isolates all the solder pads 22 independently, thereby preventing electrical breakdown and creepage.

[0113] In some implementations, please refer to Figure 1 , Figure 2 , Figure 12 and Figure 13 The electrical connector 100 also includes a sheath 30 and a conductive terminal 40. The conductive terminal 40 passes through the first through hole 12111, the clearance hole 113 and the second through hole 21. The sheath 30 partially accommodates the conductive terminal 40.

[0114] Specifically, the electrical connector 100 also includes a sheath 30 and conductive terminals 40. The conductive terminals 40 are devices used to connect and disconnect wires or cables in a circuit. The conductive terminals 40 can be configured in various forms, such as screw type, socket type, pin type, and spring clip type. The application of conductive terminals 40 facilitates the installation, removal, and replacement of wires, while ensuring the stability and safety of the circuit. Therefore, they are widely used in various electronic devices, power systems, automation equipment, and other fields. In this application, the conductive terminals 40 are designed as socket type or pin type.

[0115] Specifically, the sheath 30 is an insulating shell that wraps around and secures the conductive terminal 40. The sheath 30 is used to partially accommodate the conductive terminal 40, so as to provide mechanical support and electrical isolation for the conductive terminal 40.

[0116] In some implementations, please refer to Figure 7 , Figure 14 and Figure 15 The sheath 30 includes a terminal cavity 31 and a positioning post 32. The circuit board 20 is also provided with a positioning hole 24. The terminal cavity 31 partially accommodates the conductive terminal 40, and the positioning post 32 passes through the positioning hole 24.

[0117] Specifically, the sheath 30 is an insulating shell used to enclose the conductive terminal 40. The sheath 30 includes a terminal cavity 31 and a positioning post 32, used to fix the conductive terminal 40 and ensure assembly accuracy. The terminal cavity 31 is a cavity structure inside the sheath 30 used to accommodate the conductive terminal 40. The terminal cavity 31 partially encloses the conductive terminal 40 to fix the installation position of the conductive terminal 40. The positioning hole 24 is a hole on the circuit board 20 used to pass through the positioning post 32 of the sheath 30 to ensure the accuracy of the assembly position of the sheath 30.

[0118] In summary, the insulating component 10 in this embodiment includes an insulating pad 11, which includes a first insulating surface 111 and a second insulating surface 112. The insulating pad 11 also includes clearance holes 113 and an insulating element 114. The openings of the clearance holes 113 are respectively connected to the first insulating surface 111 and the second insulating surface 112, allowing conductive components to pass through the clearance holes 113 and through the insulating pad 11, ensuring proper installation of the conductive components. The insulating element 114 is disposed on the first insulating surface 111 and the second insulating surface 112, and between adjacent clearance holes 113, to independently isolate the conductive components passing through the insulating pad 11, thereby preventing electrical breakdown and creepage during use.
