[0038] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0039] 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 utility model, and the change or adjustment of the relative relationship is also considered as the scope of the utility model without substantial change of the technical content.

[0040] As shown in Figure 1 In an embodiment, the connector 10 includes a terminal 1 for electrically connecting the solar panel and the inverter and a temperature detection device 2a, 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.

[0041] The temperature of the terminal 1 is detected through the temperature detection device 2a, so that the temperature of the terminal 1 can be obtained in time, thereby reducing the safety hazards caused by the heating of the terminal 1.

[0042] In actual use, the temperature detection device 2a can also be in communication connection with a 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, thereby reducing the safety hazards caused by the heating of the terminal 1.

[0043] It should be understood that in addition to the terminal 1 for electrically connecting the solar panel and the inverter, the temperature detection device 2a can also be used to connect the terminal for electrically connecting other components in other application scenarios.

[0044] As shown in Figure 1 and Figure 3 In an embodiment, the temperature detection device 2a includes 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 for connecting the terminal 1; the temperature detector 2 and the terminal connecting area 3a are spaced apart along a first direction to electrically isolate the temperature detector 2 and the terminal 1 connected to the terminal connecting area 3a; the temperature detector 2 is used to detect the temperature of the terminal 1 connected to the terminal connecting area 3a. Figures 3 to 5Of the directions shown, the first direction is parallel to the X-axis.

[0045] After the temperature detection device 2a and the terminal block 1 are assembled, the temperature detector 2 and the terminal block 1 can be electrically isolated by the insulating connector 3 to avoid the large current on the terminal block 1 from having an adverse effect on the temperature detector 2.

[0046] In addition, after the temperature detection device 2a and the terminal block 1 are assembled, the terminal block 1 and the temperature detector 2 are spaced apart on the insulating connector 3 along the first direction. Moreover, at least a part of the insulating connector 3 is located between the terminal block 1 and the temperature detector 2, which can improve the electrical isolation effect between the terminal block 1 and the temperature detector 2 and avoid the large current on the terminal block 1 from having an adverse effect on the temperature detector 2.

[0047] In one embodiment, the insulating connector 3 may be made of plastic, rubber, or ceramic, etc.

[0048] like Figures 1 to 3 As shown, in one embodiment, the temperature detector 2 includes a temperature sensing element 21 and a signal line 22; the temperature sensing element 21 and the signal line 22 are electrically connected and arranged along a first direction; and / or, the signal line 22 extends along the first direction, and in the first direction, the temperature sensing element 21 is located between the signal line 22 and the terminal 1. This allows the signal line 22 to be farther away from the terminal 1 in the first direction, improving the electrical isolation effect between the two. Furthermore, the temperature sensing element 21 is communicatively connected to the controller via the signal line 22, which also allows the controller to be farther away from the terminal 1 in the first direction, thereby avoiding adverse effects of large currents on the terminal 1 on the controller.

[0049] exist Figures 1 to 3 Of the directions shown, the first direction is parallel to the X-axis.

[0050] 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.

[0051] In addition, there are two signal lines 22, which are the positive lead and the negative lead of the temperature sensing part 21, respectively.

[0052] like Figure 2 and Figure 3As shown, in one embodiment, the signal line 22 extends along a first direction, specifically, the signal line 22 extends along the direction from the terminal 1 to the temperature sensing part 21. This allows the end of the signal line 22 used to connect to the controller (i.e., the end of the terminal 1 facing away from the temperature sensing part 21) to be farther away from the terminal 1. Moreover, this helps to reduce the size of the connector 10 in other directions, which is beneficial for the miniaturization design of the connector 10.

[0053] The signal line 22 extends along a first direction, meaning that at least a portion of the signal line 22 extends along the first direction. Specifically, the entire signal line 22 extends along the first direction, or the signal line 22 may have portions extending along other directions in addition to the portion extending along the first direction. Furthermore, 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.

[0054] The temperature sensing element 21 and the signal line 22 are arranged along the first direction, which means that the signal line 22 is located on one side of the temperature sensing element in the first direction.

[0055] like Figure 2 and Figure 4 As shown, in one embodiment, the signal line 22 includes a lead 23 and a pin 24; wherein the lead 23 extends along a first direction and is electrically connected to the temperature sensing part 21; in the first direction, the pin 24 is electrically connected to the side of the signal line 22 away from the temperature sensing part 21. In this case, in the first direction, the pin 24 is connected to the side of the temperature sensing part 21 away from the terminal 1. 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 the hardness of the signal line 22.

[0056] In practical applications, since the hardness of pin 24 is greater than that of signal line 22, pin 24 is less prone to deformation compared to signal line 22. 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] like Figure 1 , Figure 5 and Figure 6 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 first surface 31 is provided with a mounting hole 33, which extends toward the second surface 32; the temperature sensing part 21 is located inside the mounting hole 33; one end of the signal line 22 is located inside the mounting hole 33 and connected to the temperature sensing part 21; the other end of the signal line 22 is located outside the mounting hole 33; the first direction is perpendicular to the second direction. In this way, the insulating connector 3 can shield and protect the temperature sensing part 21 and the signal line 22, preventing them from being damaged by collisions with external objects and improving the service life of the temperature detector 2.

[0061] exist Figure 1 Of the directions shown, the second direction is parallel to the Z-axis.

[0062] Furthermore, the portion of the temperature sensing element 21 and the signal line 22 located within the mounting hole 33 can be shielded by the insulating connector 3, isolating them from the terminal 1. The portion of the signal line 22 extending out of the mounting hole 33 (defined as the first portion) is located outside the insulating connector 3. Since the first portion is the end of the signal line 22 facing away from the temperature sensing element 21, this arrangement creates a larger gap between the first portion and the terminal 1. Thus, an insulating shielding structure is not required between the first portion and the terminal 1, ensuring electrical isolation between them.

[0063] Furthermore, when a component is mentioned in this article as being located inside a hole, it can mean that the entire component is located inside the hole, or that only a portion of the component is located inside the hole.

[0064] like Figure 4 and Figure 7As shown, in an embodiment, in the second direction, the mounting hole 33 comprises a first hole 331 and a second hole 332; the first hole 331 extends from the first surface 31 to the second surface 32; the second hole 332 is disposed on the bottom surface of the first hole 331 and penetrates to the second surface 32; the pin 24 comprises electrically connected first and second connecting portions 25 and 26; the first connecting portion 25 extends along the first direction, the second connecting portion 26 extends along the second direction, and the first connecting portion 25 is electrically connected to the temperature sensing portion 21; the temperature sensing portion 21 and the first connecting portion 25 are both located within the first hole 331; and the second connecting portion 26 extends out of the mounting hole 33 from the second hole 332.

[0065] In an embodiment, the first hole 331 is a blind hole. In the first direction, the size of the first hole 331 is greater than the size of the second hole 332. The first connecting portion 25 can abut against the bottom surface of the first hole 331.

[0066] Such arrangement can make the temperature detector 2 more stable when mounted in the mounting hole 33.

[0067] In an embodiment, the cross-sectional shape and size of the second hole 332 can match the cross-sectional shape and size of the second connecting portion 26, where the cross-sections of the two are perpendicular to the second direction. For example, the second hole 332 can be a circular hole, and the second connecting portion 26 can be a cylinder, and the diameter of the second hole 332 is equal to, slightly greater than, or slightly smaller than the diameter of the second connecting portion 26. For another example, the second hole 332 can be a rectangular hole, and the second connecting portion 26 can be a cuboid structure, and the thickness of the second hole 332 in the first direction is equal to, slightly greater than, or slightly smaller than the thickness of the second connecting portion 26 in the first direction, the width of the second hole 332 in the third direction is equal to, slightly greater than, or slightly smaller than the width of the second connecting portion 26 in the third direction, and the length of the second hole 332 in the second direction is less than the length of the second connecting portion 26 in the second direction.

[0068] In an embodiment, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction. That is, the first direction, the second direction, and the third direction are all perpendicular to each other. Figure 4 And Figure 7 In the shown direction, the third direction is parallel to the Y-axis.

[0069] In addition, when the signal line 22 is two, the two signal lines 22 can be spaced apart along the third direction. For example, Figure 6 And Figure 7As shown, in an embodiment, the bottom surface of the first hole 331 is provided with a limiting structure 34, which is used to limit the position of the first connecting part 25 relative to the insulating connecting piece 3 in the third direction. This can further improve the stability of the connection of the signal line 22 on the insulating connecting piece 3. The limiting structure 34 includes a plurality of limiting blocks 341, each of which is located on the two sides of the first connecting part 25 in the third direction, and the two sides of the first connecting part 25 can respectively abut against the corresponding limiting blocks 341 in the third direction, so as to limit the position of the signal line 22 in the third direction. "A plurality of" means greater than or equal to two, and the meaning of the term "a plurality of" in each embodiment is the same, which will not be repeated hereinafter.

[0070] In addition, after assembly, the first connecting part 25 can abut against the bottom surface of the first hole 331, so as to limit the position of the signal line 22 in the second direction, facilitating the installation of the temperature detector 2 on the insulating connecting piece 3.

[0071] It should be understood that when the number of signal lines 22 is two, the two sides of the two signal lines can abut against the limiting blocks 341 in the third direction.

[0072] In Figure 6 In the example shown, the number of limiting blocks 341 is three, and the three limiting blocks 341 are arranged at intervals along the third direction, and the signal line 22 is arranged between the two adjacent limiting blocks 341.

[0073] As Figure 7 shown, in an embodiment, the mounting hole 33 further includes a third hole 333, which is arranged on the bottom surface of the first hole 331 and is arranged at intervals with the first hole 331; in the first direction, the third hole 333 is located between the first hole 331 and the terminal 1; at least one of the temperature sensing part 21 and the signal line 22 is opposite to the third hole 333 in the second direction; and / or, at least one of the temperature sensing part 21 and the signal line 22 is located in the third hole 333.

[0074] In which, the temperature sensing part 21 opposite to the third hole 333 in the second direction can mean that at least a part of the temperature sensing part 21 is located in the first hole 331, and in a vertical projection of a plane perpendicular to the second direction, the projection of the temperature sensing part 21 and the projection of the opening formed by the third hole 333 on the bottom surface of the first hole 331 at least partially coincide.

[0075] The signal line 22 opposite to the third hole 333 in the second direction can mean that at least a part of the signal line 22 is located in the first hole 331, and in a vertical projection of a plane perpendicular to the second direction, the projection of the signal line 22 and the projection of the opening formed by the third hole 333 on the bottom surface of the first hole 331 at least partially coincide.

[0076] The third hole 333 allows the temperature sensing element 21 and the signal line 22 to be avoided, making it easier to install them inside the mounting hole 33.

[0077] Alternatively, the third hole 333 can be a blind hole that does not penetrate to the second surface 32; or, the third hole 333 can also be a through hole that penetrates to the second surface 32.

[0078] When signal line 22 includes lead 23 and pin 24, pin 24 actually extends out of mounting hole 33. At this time, pin 24 is located in second hole 332, and insulating connector 3 extends out of second hole 332. Meanwhile, in this embodiment, the first connecting part 25 and the second connecting part 26 are both part of the structure of pin 24, that is, pin 24 actually includes the first connecting part 25 and the second connecting part 26. Moreover, at this time, lead 23 is located in first hole 331, and at least one of temperature sensing part 21 and lead 23 is opposite to third hole 333 in the second direction; and / or, at least one of temperature sensing part 21 and lead 23 is located in third hole 333.

[0079] Wherein, the fact that the lead 23 is opposite to the third hole 333 in the second direction can mean that at least a portion of the lead 23 is located inside the first hole 331, and in an orthographic projection of a plane perpendicular to the second direction, the projection of the signal line 22 and the projection of the opening formed by the third hole 333 on the bottom surface of the first hole 331 at least partially overlap.

[0080] When signal line 22 includes lead 23 but not pins, lead 23 is actually located inside the second hole 332 and extends out of the mounting hole 33. Meanwhile, in this embodiment, the first connecting portion 25 and the second connecting portion 26 are both part of the lead 23 structure; that is, lead 23 actually includes the first connecting portion 25 and the second connecting portion 26.

[0081] like Figure 5 and Figure 7 As shown, in one embodiment, a notch 35 is provided on the first surface 31; in a first direction, the notch 35 unidirectionally penetrates the insulating connector 3 along the direction from the terminal connection area to the temperature detector 2; in a third direction, the notch 35 completely penetrates the insulating connector 3; in a second direction, the notch 35 is spaced apart from the bottom surface of the first hole 331, that is, it does not penetrate to the bottom surface of the first hole 331. Furthermore, in the first direction, both the insulating connector 3 and the mounting hole 33 have portions located between the notch 35 and the terminal connection area.

[0082] like Figure 1 As shown, in one embodiment, the connector 10 further includes an insulating filler 4, which fills the mounting hole 33 and covers the temperature sensing part 21, the signal line 22, and the pin 24.

[0083] The temperature sensing part 21 and the signal line 22 can be prevented from shaking in the mounting hole 33 and the signal line 22 can be prevented from deforming by the setting of the insulation filler 4, so that the temperature sensing part 21 and the signal line 22 can be kept in fixed positions, and the stability of the temperature detection of the terminal 1 can be improved.

[0084] The material of the insulation filler 4 can be epoxy resin or the like.

[0085] In addition, the insulation filler 4 can be filled in at least one of the first hole 331, the second hole 332 and the third hole 333. The insulation filler 4 can be completely filled in the mounting hole 33, or can be filled in only a part of the mounting hole 33, for example, the insulation filler 4 can be completely filled in any one of the first hole 331, the second hole 332 and the third hole 333, or the insulation filler 4 can be filled in only a part of any one of the first hole 331, the second hole 332 and the third hole 333.

[0086] In addition, the insulation filler 4 covering the temperature sensing part 21 can mean that the insulation filler 4 completely covers the temperature sensing part 21, or can mean that the insulation filler 4 covers a part of the temperature sensing part 21.

[0087] The insulation filler 4 covering the signal line 22 can mean that the insulation filler 4 covers a part of the signal line 22.

[0088] When the signal line 22 includes the lead 23 and the pin 24, the insulation filler 4 covers the lead 23, and / or the insulation filler 4 covers the pin 24.

[0089] The insulation filler 4 covering the lead 23 can mean that the insulation filler 4 completely covers the lead 23, or can mean that the insulation filler 4 covers a part of the lead 23.

[0090] The insulation filler 4 covering the pin 24 can mean that the insulation filler 4 covers a part of the pin 24.

[0091] In an embodiment, the opposite ends of the terminal 1 are respectively used for connecting a solar panel and an inverter. Specifically, in the first direction, the opposite ends of the terminal 1 are respectively used for connecting a solar panel and an inverter.

[0092] In an embodiment, the terminal 1 and the insulation connector 3 are detachably connected, so that only the damaged one can be replaced when one of them is damaged, thereby reducing the maintenance cost; or the terminal 1 and the insulation connector 3 are an integral structure, for example, when the insulation connector 3 is plastic, the insulation connector 3 and the terminal 1 can be integrally formed by injection molding.

[0093] It should be understood that when the terminal block 1 and the insulating connector 3 are an integral structure, the terminal block 1 and the insulating connector 3 cannot be disassembled.

[0094] In other embodiments, when the terminal block 1 and the insulating connector 3 are not detachable, the terminal block 1 and the insulating connector 3 can also be separately configured, but they cannot be detached after being connected.
