Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The present application will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] In related technologies, the controller is an important component of thermal management devices, including circuit board assemblies and connector assemblies. The pins of the connector assembly are mounted on the circuit board assembly. However, the connector assembly lacks a protective structure for the pins, which makes the pins prone to being bent during transportation or installation on the circuit board assembly.

[0025] Based on the above-mentioned technical problems, embodiments of this application provide a controller 100, including a circuit board assembly 110 and a connector assembly 120. The connector assembly 120 includes a pin 121 and a housing 122. The pin 121 is electrically connected to the circuit board assembly 110. The housing 122 includes a protective part 1222, which is disposed around the pin 121. The protective part 1222 is in contact with or has a gap with the circuit board assembly 110.

[0026] In this controller, the protective part 1222 is arranged around the pin 121, so that the protective part 1222 can protect the pin 121. This helps to reduce the defect of the pin 121 being bent during the transportation or installation of the connector assembly 120 on the circuit board assembly 110, and thus helps to reduce the failure rate of the controller 100.

[0027] Embodiments of this application also provide a connector assembly 120, including a pin 121 and a housing 122. The housing 122 includes a protective portion 1222, a base 1221, and an interface portion 1223. The pin 121 includes a plug section 1213, an insert section 1212, and an interface section 1211. The interface portion 1223 is disposed around the interface section 1211. The base 1221 is injection molded with the insert section 1212 as an insert. The protective portion 1222 is disposed around the plug section 1213.

[0028] In the connector assembly 120, the interface portion 1223 is arranged around the interface section 1211, and the protective portion 1222 is arranged around the plug section 1213. This allows the protective portion 1222 and the interface portion 1223 to protect the pins, which helps to reduce the defect of the pins 121 being bent during the transportation or installation of the connector assembly 120 on the circuit board assembly 110, and thus helps to reduce the failure rate of the connector assembly 120.

[0029] The following is combined with Figures 1 to 13 This application provides a detailed description of a connector assembly 120 and a controller 100. The controller 100 includes a circuit board assembly 110, a connector assembly 120, a housing assembly 130, a first fastener 140, a second fastener 150, and a third fastener 160. The circuit board assembly 110 includes a substrate 111 and circuit elements 112. The connector assembly 120 includes pins 121 and a housing 122.

[0030] In one possible implementation, the housing 122 includes a protective portion 1222, which surrounds the interface segment pin 121. The protective portion 1222 is in contact with or spaced from the circuit board assembly 110, so that the protective portion 1222 can protect the pin 121. This helps to reduce the defect of the pin 121 being bent during the transportation or installation of the connector assembly 120 on the circuit board assembly 110, and thus helps to reduce the failure rate of the controller 100.

[0031] In one possible implementation, the opening of the protective portion 1222 faces the substrate 111, and the pin 121 is electrically connected to the substrate 111 through the opening of the protective portion 1222, with at least a portion of the pin 121 located inside the protective portion 1222.

[0032] For ease of understanding, such as Figures 2 to 4 As shown, the protective part 1222 is tubular in shape. The opening of the protective part 1222 is defined as the first opening 1222a. The first opening 1222a faces the substrate 111. The pin 121 is electrically connected to the substrate 111 through the first opening 1222a. This arrangement facilitates the electrical connection between the pin 121 and the substrate 111. Figure 1 In the Cartesian coordinate system shown, the X-axis direction is defined to be consistent with one inner and outer direction of the controller 100, and the Z-axis direction is defined to be consistent with another inner and outer direction of the controller 100. Some of the pins 121 are located inside the protective part 1222, that is, inside the cavity of the protective part 1222, so that the protective part 1222 can protect the pins 121. This is beneficial to reduce the defect of the pins 121 being bent during the transportation or installation of the connector assembly 120 on the substrate 111, etc., and thus helps to reduce the failure rate of the connector assembly 120 and the failure rate of the controller 100.

[0033] In one possible implementation, the housing 122 includes a base 1221, the bottom wall of which is disposed opposite to the top wall of the substrate 111, the opening of the protective portion 1222 faces the top wall of the substrate 111, and the protective portion 1222 extends from the bottom wall of the base 1221 toward the top wall of the substrate 111.

[0034] For ease of understanding, such as Figures 2 to 4 In the Cartesian coordinate system shown, the Y-axis direction is defined as pointing upwards from the controller 100, and the direction away from the Y-axis direction is pointing downwards from the controller 100. The substrate 111 is located below the base 1221. The extension direction of the protective part 1222 is consistent with the direction away from the Y-axis. The protective part 1222 extends downwards from the base 1221, that is, it extends towards the base 1221. This arrangement makes the structure of the protective part 1222 and the substrate 111 more compact, which is conducive to the protective part 1222 being closer to the substrate 111, and thus conducive to the protective part 1222 better protecting the pin 121.

[0035] In one possible implementation, the opening of the protective part 1222 is located on the bottom wall of the protective part 1222, and a gap is provided between the bottom wall of the protective part 1222 and the top wall of the substrate 111, with the opening of the protective part 1222 communicating with the gap.

[0036] For ease of understanding, such as Figures 2 to 4 As shown, the gap between the bottom wall of the protective part 1222 and the top wall of the substrate 111 is defined as the first gap E1, and the first gap E1 is connected to the first opening 1222a. When the pin 121 is energized, the pin 121 can generate heat, and this heat can be dissipated through the first opening 1222a and the first gap E1. This arrangement is beneficial for the pin 121 to dissipate heat.

[0037] In one possible implementation, the housing 122 includes a first protrusion 1224 that extends from the bottom wall of the protective portion 1222 toward the top wall of the substrate 111 and is able to abut against the substrate 111.

[0038] For ease of understanding, such as Figures 2 to 4 , Figures 6 to 12 As shown, the first protrusion 1224 is located below the protective portion 1222. The first protrusion 1224 extends downward from the bottom wall of the protective portion 1222. The bottom wall of the first protrusion 1224 can abut against the top wall of the substrate 111. The first protrusion 1224 can provide support, which helps to improve the stability of the housing 122 on the substrate 111, and thus helps the protective portion 1222 to better protect the pin 121.

[0039] In one possible implementation, the bottom wall of the first protrusion 1224 can abut against the top wall of the substrate 111. A plane obtained by cutting the first protrusion 1224 along a direction perpendicular to its extension is defined as the first cross-section D1. The first cross-section D1 is closer to the bottom wall of the base 1221 than the bottom wall of the first protrusion 1224. The area of ​​the bottom wall of the first protrusion 1224 is smaller than the area of ​​the first cross-section D1.

[0040] For ease of understanding, such as Figures 6 to 12 As shown, the cross section pointed to by D1 is a first cross section, which is parallel to the X-axis and Z-axis and perpendicular to the Y-axis. The plane pointed to by D2 is the bottom wall of the first protrusion 1224. The area of ​​the bottom wall of the first protrusion 1224 is smaller than the area of ​​the first cross section D1. On the one hand, this arrangement helps to reduce the contact area between the first protrusion 1224 and the substrate 111, thereby improving the support stability between the housing 122 and the substrate 111. On the other hand, this arrangement helps to increase the flow area of ​​the first gap, thereby improving the heat dissipation effect of the pin 121.

[0041] Furthermore, the first protrusion 1224 includes a wide plate segment 1224a and a narrow plate segment 1224b, with a portion of the wide plate segment 1224a located on the upper side of the narrow plate segment 1224b, and the bottom wall of the narrow plate segment 1224b being able to abut against the top wall of the substrate 111.

[0042] For ease of understanding, such as Figure 9 As shown, the protective part 1222, the wide plate segment 1224a, the narrow plate segment 1224b, and the rod part 1226 are arranged sequentially from top to bottom. The width direction of the wide plate segment 1224a is perpendicular to the Y-axis direction, and the width direction of the wide plate segment 1224a is consistent with the width direction of the narrow plate segment 1224b. The width of the wide plate segment 1224a is greater than the width of the narrow plate segment 1224b, which makes the bottom wall of the narrow plate segment 1224b smaller. The smaller bottom wall of the narrow plate segment 1224b can abut against the top wall of the substrate 111, thereby reducing the contact area between the first protrusion 1224 and the substrate 111, which is more conducive to improving the positioning accuracy of the connector assembly 120 and the substrate 111. The width direction of the protective part 1222 is consistent with the width direction of the wide plate segment 1224a. The width of the protective part 1222 is greater than the width of the wide plate segment 1224a. The widths of the protective part 1222, the wide plate segment 1224a and the narrow plate segment 1224b decrease step by step. On the one hand, this helps to reduce the contact area between the first protrusion 1224 and the substrate 111. On the other hand, it also helps to improve the structural strength of the first protrusion 1224.

[0043] In one possible implementation, the housing 122 includes a rod 1226, and the base plate 111 has a positioning hole 1111. The extending direction of the positioning hole 1111 and the extending direction of the rod 1226 are consistent with the extending direction of the first protrusion 1224. The outer wall of the rod 1226 and the inner wall forming the positioning hole 1111 can be matched for limiting.

[0044] For ease of understanding, such as Figure 9 As shown, the rod 1226 extends downward from the narrow plate segment 1224b. The length direction of the rod 1226 is the extension direction of the rod 1226. The axial direction of the positioning hole 1111 is the extension direction of the positioning hole 1111. The extension direction of the first protrusion 1224 is consistent with the direction away from the Y-axis. The rod 1226 is approximately located in the positioning hole 1111. The outer wall of the rod 1226 is matched with the inner wall of the positioning hole 1111, so that the housing 122 is positioned on the base plate 111, which is more conducive to the protective part 1222 better protecting the pin 121.

[0045] In one possible implementation, there are two first protrusions 1224, which are located on opposite sides of the first opening 1222a, and the two first protrusions 1224 serve as multi-point supports.

[0046] In one possible implementation, the housing 122 further includes a second protrusion 1225, the cross-sectional area of ​​which gradually decreases from the protective portion 1222 toward the substrate 111, and the bottom wall of the second protrusion 1225 is able to abut against the top wall of the substrate 111.

[0047] For ease of understanding, such as Figure 6 , Figure 9 and Figure 12 As shown, there are two second protrusions 1225, which are respectively disposed on opposite sides of the first opening 1222a. The second protrusions 1225 are generally plate-shaped, and their outer contours are generally triangular or trapezoidal. The bottom wall of the second protrusion 1225 is parallel to its cross-section, and the cross-section of the second protrusion 1225 is also parallel to the bottom wall of the protective part 1222. Along the direction away from the Y-axis, the cross-sectional area of ​​the second protrusion 1225 gradually decreases, making the bottom wall of the second protrusion 1225 smaller. The smaller bottom wall of the second protrusion 1225 can abut against the top wall of the substrate 111, thereby reducing the contact area between the second protrusion 1225 and the substrate 111 and improving the support stability between the housing 122 and the substrate 111.

[0048] In one possible implementation, the housing 122 includes an interface portion 1223, which is disposed around the pin 121. The opening of the interface portion 1223 faces away from the substrate 111, and a portion of the pin 121 is located inside the interface portion 1223.

[0049] For ease of understanding, such as Figure 1 , Figure 2 and Figure 13 As shown, the interface portion 1223 is also tubular in shape, extending upward from the top wall of the base 1221. A portion of the pins 121 are located within the interface portion 1223. The opening of the interface portion 1223 is defined as the second opening 1223a, which faces upward. When the controller 100 is used as a component of a thermal management device, the wiring harness 200 of the thermal management device can be inserted into the interface portion 1223 and electrically connected to the pins 121 within it.

[0050] In one possible implementation, the pin 121 includes an interface segment 1211, an insert segment 1212, and a plug segment 1213. At least a portion of the interface segment 1211 is located inside the interface portion 1223. The housing 122 is injection molded with the insert segment 1212 as an insert. The plug segment 1213 is welded and fixed to the substrate 111. A portion of the plug segment 1213 is located inside the protective portion 1222.

[0051] For ease of understanding, such as Figures 9 to 11As shown, interface segment 1211 is located at one end of insert segment 1212, and plug segment 1213 is located at the other end of insert segment 1212. Interface segment 1211 is basically located in the inner cavity of interface portion 1223. Base 1221 is injection molded with insert segment 1212 as an insert. This insert injection molding structure makes the positional accuracy of pin 121 and housing 122 higher, which is beneficial to improving the assembly quality of connector assembly 120 and circuit board assembly 110, and thus more beneficial to reducing the failure rate of connector assembly 120 and controller 100. Part of plug segment 1213 is located in the inner cavity of protective portion 1222. The substrate 111 has metal through hole 1112, and part of plug segment 1213 is located in metal through hole 1112. Plug segment 1213 is welded and fixed to the inner wall forming metal through hole 1112.

[0052] In one possible implementation, the circuit board assembly 110 includes a circuit element 112 electrically connected to the substrate 111. The circuit element 112 is located outside the protective portion 1222. The housing 122 includes a flange portion 1228 that protrudes outward from the outer peripheral wall of the housing 122. A portion of the circuit element 112 is located between the bottom wall of the flange portion 1228 and the top wall of the substrate 111.

[0053] For ease of understanding, such as Figure 6 , Figure 8 and Figure 12 As shown, circuit element 112 is soldered and fixed to substrate 111. Circuit element 112 includes, but is not limited to, at least one of capacitor, resistor, and driver chip. Circuit element 112 is basically located outside of protective part 122, so that protective part 122 separates circuit element 112 and pin 121. On the one hand, it helps to reduce the defect of pin 121 being bent by circuit element 112 during the installation of connector assembly on substrate 111, and thus further helps to reduce the failure rate of controller 100. On the other hand, when current flows through pin 121, heat is generated. Protective part 122 can reduce the impact of heat generated by pin 121 on circuit element 112, which helps to reduce the problem of overheating of circuit element 112, and thus further helps to reduce the failure rate of controller 100.

[0054] The circuit element 112 is located below the flange 1228 and above the substrate 111, so that the circuit element 112 can utilize the space between the flange 1228 and the substrate 111. This is beneficial to improving the structural compactness of the connector assembly 120 and the circuit board assembly 110, which in turn is more beneficial to improving the effective utilization rate of the substrate 111 and more beneficial to reducing the size of the controller 100.

[0055] In one possible implementation, the controller 100 includes a housing assembly 130, a flange 1228 and a protective portion 1222 located in a receiving cavity 133 of the housing assembly 130, the flange 1228 being sealed to the inner wall forming the receiving cavity 133. The flange 1228 is generally annular and located outside the outer peripheral wall of the interface portion 1223. The housing assembly 130 includes an opening 1311 through which the interface portion 1223 extends outside the housing assembly 130. The opening 1311 is substantially located inside the flange 1228, such that the opening of the opening 1311 is separated from the receiving cavity 133 of the housing assembly 130, which helps to improve the sealing effect of the housing assembly 130.

[0056] In one possible implementation, the circuit element 112 is spaced apart from the outer wall of the protective part 1222, and the pin 121 is spaced apart from the inner wall of the protective part 1222.

[0057] For ease of understanding, such as Figure 2 , Figure 3 , Figure 8 and Figure 13 As shown, the gap between the circuit element 112 and the outer wall of the protective part 1222 is very small, so that the circuit element 112 and the protective part 1222 are very close. The gap between the pin 121 and the inner wall of the protective part 1222 is also small, so that the pin 121 and the protective part 1222 are very close. This improves the compactness of the layout of the circuit element 112 and the pin 121 on the substrate 111, which in turn helps to improve the effective utilization of the substrate 111 and further helps to reduce the size of the controller 100.

[0058] In one possible implementation, the flange portion 1228 is located in the receiving cavity 133 of the housing 122. The flange portion 1228 includes a washer portion 1228a, which protrudes upward from the top wall of the flange portion 1228. The washer portion 1228a abuts against the inner wall forming the receiving cavity 133 and is in a compressed state.

[0059] For ease of understanding, such as Figure 3 , Figure 9 and Figure 11 As shown, the washer portion 1228a and the flange portion 1228 are integral structures. The washer portion 1228a is approximately ring-shaped and is located between the top wall of the flange portion 1228 and the inner wall forming the receiving cavity 133. The washer portion 1228a is compressed by the flange portion 1228 and the housing assembly 130, making the housing assembly 130 fit more tightly with the housing 122, which is more conducive to improving the sealing effect of the controller 100.

[0060] In one possible implementation, the first fastener 140 is engaged with the flange portion 1228 and the housing assembly 130, with at least a portion of the first fastener 140 located inside the washer portion 1228a.

[0061] For ease of understanding, such as Figure 6 As shown, the flange portion 1228 has a first connecting hole 1228b, and the housing assembly 130 has a second connecting hole 1312. A portion of the first fastener 140 is located in the first connecting hole 1228b and the second connecting hole 1312. The axial direction of the first connecting hole 1228b and the axial direction of the second connecting hole 1312 are aligned with the Y-axis direction. The first fastener 140 can be a bolt. The first fastener 140 can be in a limiting fit with the inner wall forming the first connecting hole 1228b and the inner wall forming the second connecting hole 1312, which helps to improve the fit between the flange portion 1228 and the housing assembly 130. The first fastener 140 is located inside the washer portion 1228a, and the washer portion 1228a also provides a sealing effect for the first fastener 140, the first connecting hole 1228b, and the second connecting hole 1312.

[0062] In one possible implementation, the second fastener 150 is positioned in a limiting engagement with the substrate 111 and the housing assembly 130.

[0063] For ease of understanding, such as Figure 6 , Figure 7 , Figures 9 to 11 As shown, the substrate 111 has a third connecting hole 1113, the housing assembly 130 has a fourth connecting hole 1313, and a portion of the second fastener 150 is located in the third connecting hole 1113 and the fourth connecting hole 1313. The axial direction of the third connecting hole 1113 and the axial direction of the fourth connecting hole 1313 are consistent with the Y-axis direction. The second fastener 150 can be a bolt. The second fastener 150 can be limited and engaged with the inner wall forming the third connecting hole 1113 and the inner wall forming the fourth connecting hole 1313. This is beneficial to improving the fit between the pin 121 and the substrate 111.

[0064] In one possible implementation, the housing assembly 130 includes an upper cover 131, a lower cover 132, and a third fastener 160.
