[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0045] The terms such as "upper", "lower", "left", "right", etc. cited in the specification are only for the convenience of clear description and are not used to limit the scope of the present application. The change or adjustment of the relative relationship without substantial change of the technical content is also regarded as the scope of the present application.

[0046] As Figure 1 and Figure 2As shown in the drawings, in an embodiment, the connector 10 comprises the terminal 1 and the temperature detection device 2a, the terminal 1 is used for electrically connecting the solar panel and the inverter, the terminal 1 is connected with the temperature detection device 2a, and the temperature of the terminal 1 can be detected through the temperature detection device 2a.

[0047] In this way, the temperature of the terminal 1 can be obtained in time, so as to reduce the security risks caused by the heat of the terminal 1.

[0048] In actual use, the temperature detection device 2a can also be in communication connection with the controller, and the detection result of the temperature detection device 2a can also be transmitted to the controller, so that when the temperature of the terminal 1 is too high, corresponding protection measures can be taken through the controller, such as cutting off the circuit where the terminal 1 is located, cooling the terminal 1, and sending an alarm to the outside, so as to reduce the security risks caused by the heat of the terminal 1.

[0049] It should be understood that, in addition to being connected to the terminal 1 for electrically connecting the solar panel and the inverter, the temperature detection device 2a can also be used to connect a terminal for electrically connecting other components in other application scenarios.

[0050] As shown in the drawings, Figure 1 and Figure 3 In an embodiment, the temperature detection device 2a comprises a temperature detector 2 and an insulating connecting piece 3; the temperature detector 2 is connected to the insulating connecting piece 3; the insulating connecting piece 3 is provided with a terminal connecting area 3a, the terminal connecting area 3a is used for connecting the terminal 1; the temperature detector 2 and the terminal connecting area 3a are spaced apart along a first direction, so as to electrically isolate the temperature detector 2 and the terminal 1 connected to the terminal connecting area 3a; the temperature detector 2 is used for detecting the temperature of the terminal 1 connected to the terminal connecting area 3a. Figure 3 to Figure 5 In the direction shown in the drawings, the first direction is parallel to the X axis.

[0051] After the temperature detection device 2a and the terminal 1 are assembled, the temperature detector 2 and the terminal 1 can be electrically isolated through the insulating connecting piece 3, so as to avoid the adverse effects of the large current on the terminal 1 on the temperature detector 2.

[0052] In addition, after the temperature detection device 2a and the terminal 1 are assembled, the terminal 1 and the temperature detector 2 are spaced apart along the first direction on the insulating connecting piece 3, and at least a part of the insulating connecting piece 3 is located between the terminal 1 and the temperature detector 2, so as to improve the electrical isolation effect of the terminal 1 and the temperature detector 2.

[0053] In one embodiment, the insulating connector 3 may be made of plastic, rubber, or ceramic, etc.

[0054] like Figure 3 to Figure 5 As shown, in one embodiment, the temperature detector 2 includes a temperature sensing part 21 and a signal line 22, which are electrically connected, and the signal line 22 extends along a second direction, and / or the temperature sensing part 21 and the signal line 22 are arranged along the second direction; wherein the first direction is perpendicular to the second direction. This can reduce the maximum size of the temperature detector 2 in the first direction, thereby facilitating the miniaturization design of the connector 10.

[0055] exist Figure 3 to Figure 5 Of the directions shown, the second direction is parallel to the Z-axis.

[0056] The temperature sensing element 21 can be a thermistor, and the signal line 22 is a lead of the thermistor. Alternatively, the temperature sensing element 21 may also include a thermistor and a package structure for encapsulating the thermistor. In this case, the signal line 22 can be the portion of the thermistor's lead located outside the package structure. Furthermore, the configuration of the temperature sensing element 21 and the signal line 22 can both employ existing technology, which will not be elaborated upon in this embodiment.

[0057] Furthermore, the signal line 22 extending along the second direction means that at least a portion of the signal line 22 extends along the second direction. Specifically, the entire signal line 22 extends along the second direction, or, in addition to having a portion extending along the second direction, the signal line 22 may also have portions extending along other directions, such as a portion extending along the first direction. Moreover, when a portion of the signal line 22 extends along a certain direction, the length of that portion may be parallel to that direction, or the length direction of that portion may form an acute or obtuse angle with that direction, meaning that the length of that portion has a component in that direction.

[0058] The temperature sensing element 21 and the signal line 22 are arranged along the second direction, that is, the signal line 22 is located on one side of the temperature sensing element in the second direction. This helps to further reduce the maximum size of the temperature detector 2 in the first direction.

[0059] It should be understood that there are two signal lines 22, which are the positive lead and the negative lead of the temperature sensing part 21, respectively.

[0060] In one embodiment, the two signal lines 22 may be spaced apart along a third direction, wherein the third direction is perpendicular to the first direction and perpendicular to the second direction. Figure 4 and Figure 5 In the direction shown, the third direction is parallel to the Y-axis.

[0061] likeFigure 4 and Figure 6 As shown, in one embodiment, the signal line 22 includes a lead 23 and a pin 24; wherein the lead 23 extends along a second direction and is electrically connected to the temperature sensing part 21; furthermore, in the second direction, the pin 24 is electrically connected to the end of the lead 23 opposite to the temperature sensing part 21. In use, the signal line 22 is electrically connected to the controller through the pin 24. Furthermore, the hardness of the pin 24 is greater than that of the lead 23.

[0062] In practical applications, since the hardness of pin 24 is greater than that of lead wire 23, pin 24 is less prone to deformation compared to lead wire 23. This effectively prevents pin 24 from deforming and short-circuiting with surrounding conductive parts after it is connected to electrical connection components, thus improving the safety of temperature detector 2.

[0063] In addition, the pin 24 has relatively high rigidity, which allows it to be plugged into and mated with the corresponding electrical connection parts in devices such as controllers, thereby improving the ease of use of the temperature detector 2.

[0064] Furthermore, the cross-section of the lead can be circular, elliptical, rectangular, or other various shapes, and the lead can be straight, curved, or bent. The cross-section of the pin can be circular, elliptical, rectangular, or other various shapes, and the lead can be straight, curved, or bent.

[0065] It should be understood that in other embodiments, the signal line 22 may also have only leads 23 and no pins 24. In this case, the leads 23 may be electrically connected to electrical connection components such as controllers, thereby realizing the electrical connection between the signal line 22 and the electrical connection components.

[0066] like Figure 7 and Figure 8 As shown, in one embodiment, in the second direction, the insulating connector 3 has a first surface 31 and a second surface 32 disposed opposite to each other; the second surface 32 is provided with a mounting hole 33 extending toward the first surface 31; the temperature sensing part 21 is located inside the mounting hole 33; in the second direction, one end of the signal line 22 near the temperature sensing part 21 is located inside the mounting hole 33 and connected to the temperature sensing part 21, and the other end of the signal line 22 away from the temperature sensing part 21 extends out of the mounting hole 33 from the second surface 32. In this way, the insulating connector 3 can shield and protect the temperature sensing part 21, preventing it from being damaged by impacts from external objects and improving the service life of the temperature detector 2.

[0067] Additionally, when the signal line 22 includes a lead 23 and a pin 24, the lead 23 may be completely located within the mounting hole 33, one end of the pin 24 may be located within the mounting hole 33 to be electrically connected to the lead 23, and the end of the pin 24 away from the lead 23 may extend from the second surface 32 into the mounting hole 33.

[0068] like Figure 8 As shown, in one embodiment, the mounting hole 33 is a blind hole that does not penetrate to the first surface 31.

[0069] like Figure 1 , Figure 8 and Figure 9 As shown, in one embodiment, the connector 10 further includes an insulating shield 4 connected to the insulating connector 3. At least a portion of the insulating shield 4 is located between the signal line 22 and the terminal 1 connected to the terminal connection area 3a. The portion of the insulating shield 4 located between the signal line 22 and the terminal 1 connected to the terminal connection area 3a (defined as the first portion) protrudes from the signal line 22 in a second direction and along the direction from the first surface 31 to the second surface 32.

[0070] The first part can also be located between the signal line 22 and the terminal connection area 3a, thereby making the first part located between the signal line 22 and the terminal 1 connected to the terminal connection area 3a.

[0071] Wherein, the first part protrudes the signal line 22 in the second direction and along the direction from the first surface 31 to the second surface 32, which can mean that in the second direction, the height of the end face of the first part away from the first surface relative to the second surface 32 is greater than the height of the end face of the signal line 22 away from the first surface 31 relative to the second surface 32. That is, in the second direction, the distance between the surface of the first part that is furthest from the first surface 31 and the second surface 32 is greater than the distance between the surface of the signal line 22 that is furthest from the first surface 31 and the second surface 32.

[0072] This improves the electrical isolation between the portion of the signal line 22 extending from the insulating connector 3 and the terminal 1, thereby enhancing the electrical isolation between the temperature detector 2 and the terminal 1. Furthermore, the insulating shield 4 allows the first portion of the signal line 22 to be closer to the terminal 1 in the first direction, facilitating the miniaturization of the connector 10.

[0073] The insulating shield 4 can be made of plastic, rubber, or ceramic, etc.

[0074] In one embodiment, the insulating connector 3 and the insulating shield 4 can be an integral structure, for example, both can be made of plastic, and in this case, they can be integrally molded by injection molding. Of course, in other embodiments, the insulating connector 3 and the insulating shield 4 can also be separate components, and they can be fixed together by snap-fitting or by connecting them with bolts or other connectors.

[0075] like Figure 8As shown in the embodiment, the insulating shield 4 is arranged on the second surface 32. In this way, the insulating shield 4 is arranged to protrude the signal line 22 in the direction from the first surface 31 to the second surface 32, which is more conducive to the signal line 22.

[0076] As shown in the embodiment, the insulating shield 4 is arranged on the second surface 32. In this way, the insulating shield 4 is arranged to protrude the signal line 22 in the direction from the first surface 31 to the second surface 32, which is more conducive to the signal line 22. Figure 1 As shown in the embodiment, the insulating shield 4 is arranged on the second surface 32. In this way, the insulating shield 4 is arranged to protrude the signal line 22 in the direction from the first surface 31 to the second surface 32, which is more conducive to the signal line 22.

[0077] In this way, the shielding and protection effect of the insulating shield 4 on the signal line 22 can be further improved, and the electrical connection between the signal line 22 and the external electrical connection component is also facilitated.

[0078] The axial direction of the open loop structure can be parallel to the first direction, or the axial direction of the open loop structure can also be an acute angle or an obtuse angle with the first direction.

[0079] In addition, the insulating shield 4 can also be arranged outside the opening formed by the avoidance hole on the second surface 32.

[0080] In the embodiment, the shape of the insulating shield 4 can match the insulating connecting member 3. For example, in the examples shown in Figure 1 and Figure 9 the insulating connecting member 3 is in a cuboid structure, wherein the first direction is the thickness direction of the insulating connecting member 3, the second direction is the length direction of the insulating connecting member 3, and the third direction is the width direction of the insulating connecting member 3. At this time, the insulating shield 4 can be a square ring, wherein the width direction of the insulating shield 4 is parallel to the width direction of the insulating connecting member 3, the width of the insulating shield 4 can be equal to the width of the insulating connecting member 3, the thickness direction of the insulating shield 4 is parallel to the thickness direction of the insulating connecting member 3, and the thickness of the insulating shield 4 can be equal to the thickness of the insulating connecting member 3.

[0081] In addition, the mounting hole 33 can be a rectangular hole, wherein the thickness direction of the mounting hole 33 is parallel to the first direction, the length direction of the mounting hole 33 is parallel to the second direction, and the width direction of the mounting hole 33 is parallel to the third direction.

[0082] As shown in the embodiment, the insulating shield 4 is arranged on the second surface 32. In this way, the insulating shield 4 is arranged to protrude the signal line 22 in the direction from the first surface 31 to the second surface 32, which is more conducive to the signal line 22. Figure 8 and Figure 10As shown, when the insulation connecting piece 3 is the above-mentioned cuboid and the mounting hole 33 is the above-mentioned rectangular hole, the hole wall of the mounting hole 33 includes a first side wall 331, a second side wall 332, a third side wall 333, a fourth side wall 334, and a top wall 335, and the first side wall 331, the second side wall 332, the third side wall 333, the fourth side wall 334, and the top wall 335 enclose the mounting hole 33; wherein the first side wall 331 and the second side wall 332 are arranged in the second direction, the third side wall 333 and the fourth side wall 334 are arranged in the third direction, the two ends of the first side wall 331 in the third direction are connected to the third side wall 333 and the fourth side wall 334 respectively, and the two ends of the second side wall 332 in the third direction are connected to the third side wall 333 and the fourth side wall 334 respectively; in the second direction, the first side wall 331, the second side wall 332, the third side wall 333, and the fourth side wall 334 are all connected to the same side of the top wall 335.

[0083] The first surface 31 is the surface of the top wall 335 away from the first side wall 331 in the second direction, and the bottom surface of the mounting hole 33 is at least a part of the surface of the top wall 335 close to the first side wall 331 in the second direction.

[0084] The second surface 32 includes the surface of the first side wall 331 away from the top wall 335, the surface of the second side wall 332 away from the top wall 335, the surface of the third side wall 333 away from the top wall 335, and the surface of the fourth side wall 334 away from the top wall 335. In addition, the surface of the first side wall 331 away from the top wall 335, the surface of the second side wall 332 away from the top wall 335, the surface of the third side wall 333 away from the top wall 335, and the surface of the fourth side wall 334 away from the top wall 335 can be arranged flush, at this time, the second surface 32 is a plane, and the plane can be perpendicular to the second direction.

[0085] Wherein, in the first direction, at least a part of the area of the surface of the first side wall 331 away from the second side wall 332 is the terminal connecting area 3a. After assembly, in addition, in the first direction, the first side wall 331 is located between the second side wall 332 and the terminal 1.

[0086] As shown in Figure 8 , Figure 10 and Figure 11 In an embodiment, the inner surface of the insulation connecting piece 3 is provided with a mounting groove 34, and the mounting groove 34 penetrates to the second surface 32; wherein the inner surface of the insulation connecting piece 3 is used to enclose the mounting hole 33; the signal line is arranged in the mounting groove 34 and extends out of the mounting hole 33 from the mounting groove 34.

[0087] Wherein, the signal line 22 is clamped in the mounting groove 34, at this time, the two side walls in the width direction of the mounting groove 34 can respectively abut against the signal line 22, which can avoid the temperature detector 2 from shaking in the mounting hole 33.

[0088] In addition, in the first direction, the mounting hole 33 can be located between the mounting groove 34 and the terminal 1, so that the signal line 22 is farther away from the terminal 1, and the electrical isolation effect of the two is improved.

[0089] Specifically, the mounting groove 34 can be arranged on the second side wall 332 and located on the surface of the second side wall 332 close to the first side wall 331. At this time, the width direction of the mounting groove 34 is parallel to the third direction.

[0090] As shown in Figure 8 , in an embodiment, in the second direction, the mounting groove 34 is arranged spaced from the bottom surface of the mounting hole 33, that is, in the second direction, the mounting groove 34 does not extend to the bottom surface of the mounting hole 33.

[0091] In addition, the signal line 22 includes a first connecting portion 25, a second connecting portion 26 and a third connecting portion 27 connected in sequence; in the first direction, the first connecting portion 25 is located between the second connecting portion 26 and the terminal 1, and the second connecting portion 26 is located between the third connecting portion 27 and the terminal 1; in the second direction, the first connecting portion 25 is located between the second connecting portion 26 and the temperature sensing portion 21, and the second connecting portion 26 is located between the third connecting portion 27 and the temperature sensing portion 21; the first connecting portion 25 is electrically connected with the temperature sensing portion 21; the second connecting portion 26 is located in the mounting groove 34, and in the second direction, the second connecting portion 26 abuts against the groove wall of the mounting groove 34; the third connecting portion 27 is located in the mounting groove 34 and extends out of the mounting hole 33.

[0092] Among them, the signal line 22 is in a Z-shaped structure, after assembly, one end of the first connecting portion 25 away from the second connecting portion 26 connects the temperature sensing portion 21, and one end of the third connecting portion 27 away from the second connecting portion 26 extends out of the mounting hole. In addition, through the abutment of the second connecting portion 26 and the groove wall of the mounting groove 34, the movement of the signal line 22 along the direction from the second surface 32 to the first surface 31 relative to the insulating connecting piece 3 can be avoided, so that the plug-in cooperation of the signal line 22 and the electrical connecting component is more facilitated.

[0093] As shown in Figure 10 and Figure 11 , in an embodiment, the groove wall of the mounting groove 34 is provided with a first limiting structure 35, and the signal line 22 is provided with a second limiting structure 28 (refer to Figure 6 ); the first limiting structure 35 and the second limiting structure 28 cooperate to limit the position of the signal line 22 in the depth direction of the mounting groove 34. This arrangement can better limit the installation position of the signal line 22 on the insulating connecting piece 3.

[0094] The depth direction of the mounting groove 34, the width direction of the mounting groove 34 and the length direction of the mounting groove 34 can be perpendicular to each other. In addition, the length direction of the mounting groove 34 can be the first direction.
