[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The terms such as "upper", "lower", "left", "right", etc. cited in this specification are only for the convenience of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships should be regarded as within the scope of the invention without substantially changing the technical content.

[0024] like Figure 1 As shown, in one embodiment, the connector 10 includes a terminal 1 and a temperature detection device 2a, the terminal 1 is used to electrically connect the solar panel and the inverter, the terminal 1 is connected to the temperature detection device 2a, and the temperature of the terminal 1 can be detected by the temperature detection device 2a.

[0025] The temperature of the connection terminal 1 is detected by the temperature detection device 2a, so that the temperature of the connection terminal 1 can be obtained in time, which is helpful to reduce the safety hazard caused by the heating of the connection terminal 1.

[0026] In actual use, the temperature detection device 2a can also be connected to the controller for communication, 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, the controller can take corresponding protective measures, such as cutting off the circuit where the terminal 1 is located, cooling the terminal 1, and issuing an alarm prompt, etc., thereby reducing the safety hazards caused by the heating of the terminal 1.

[0027] It should be understood that, in addition to being connected to the wiring terminals 1 for realizing electrical connection between the solar panel and the inverter, in other application scenarios, the temperature detection device 2a can also be used to connect to the wiring terminals for realizing electrical connection of other components.

[0028] like Figure 1 and Figure 3 As shown, in one embodiment, the temperature detection device 2a includes a temperature detector 2 and an insulating connector 3; the temperature detector 2 is connected to the insulating connector 3; the insulating connector 3 is provided with a terminal connection area 3a, and the terminal connection area 3a is used to connect the wiring terminal 1; the temperature detector 2 and the terminal connection area 3a are arranged at intervals along a first direction so as to electrically isolate the temperature detector 2 and the wiring terminal 1 connected to the terminal connection area 3a; the temperature detector 2 is used to detect the temperature of the wiring terminal 1 connected to the terminal connection area 3a. Figures 3 to 5 In the directions shown, the first direction is parallel to the X-axis.

[0029] After the temperature detection device 2 a and the wiring terminal 1 are assembled, the temperature detector 2 and the wiring terminal 1 can be electrically isolated by the insulating connector 3 , so as to prevent the large current on the wiring terminal 1 from having an adverse effect on the temperature detector 2 .

[0030] 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 on the insulating connector 3 along the first direction, and at least a portion of the insulating connector 3 is located between the terminal 1 and the temperature detector 2, which can improve the electrical isolation effect of the terminal 1 and the temperature detector 2 and avoid the large current on the terminal 1 from having an adverse effect on the temperature detector 2.

[0031] In one embodiment, the insulating connector 3 may be made of plastic, rubber, ceramic or the like.

[0032] like Figures 1 to 3 As shown, in one embodiment, the temperature detector 2 includes a temperature sensing portion 21 and a signal line 22; the temperature sensing portion 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 portion 21 is located between the signal line 22 and the wiring terminal 1. In this way, the signal line 22 can be farther away from the wiring terminal 1 in the first direction, thereby improving the electrical isolation effect between the two. Moreover, the temperature sensing portion 21 is connected to the controller through the signal line 22, which can also make the controller away from the wiring terminal 1 in the first direction, thereby avoiding the adverse effect of the large current on the wiring terminal 1 on the controller.

[0033] exist Figures 1 to 3 In the directions shown, the first direction is parallel to the X-axis.

[0034] The temperature sensing portion 21 may be a thermistor, and the signal line 22 is a lead wire of the thermistor. Alternatively, the temperature sensing portion 21 may also include a thermistor and a packaging structure for packaging the thermistor, and in this case, the signal line 22 may be the portion of the lead wire of the thermistor that is located outside the packaging structure. In addition, the arrangement of the temperature sensing portion 21 and the signal line 22 may adopt the existing technology, and this embodiment will not be described in detail here.

[0035] In addition, the number of the signal lines 22 is two, and the two signal lines 22 are respectively a positive lead line and a negative lead line of the temperature sensing portion 21 .

[0036] like Figure 2 and Figure 3 As shown, in one embodiment, the signal line 22 extends along the first direction, specifically: the signal line 22 extends along the direction from the connection terminal 1 to the temperature sensing portion 21, so that the end of the signal line 22 used for connecting to the controller (i.e., the end of the connection terminal 1 away from the temperature sensing portion 21) is farther away from the connection terminal 1. Moreover, this is conducive to reducing the size of the connector 10 in other directions, and is conducive to the miniaturization design of the connector 10.

[0037] The signal line 22 extends along the first direction, which means 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, in addition to the portion extending along the first direction, the signal line 22 may also have a portion extending along other directions. Moreover, when a portion of the signal line 22 extends along a certain direction, the length of the portion may be parallel to the direction, or the length direction of the portion may also be an acute angle or an obtuse angle with the direction, that is, at this time, the length of the portion has a component in the direction.

[0038] The temperature sensing portion 21 and the signal line 22 are arranged along the first direction, which means that the signal line 22 is located at one side of the temperature sensing portion in the first direction.

[0039] 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 the lead 23 is electrically connected to the temperature sensing portion 21; in the first direction, the pin 24 is electrically connected to the side of the signal line 22 away from the temperature sensing portion 21. At this time, in the first direction, the pin 24 is connected to the side of the temperature sensing portion 21 away from the terminal 1. When in use, the signal line 22 is electrically connected to the controller through the pin 24. In addition, the hardness of the pin 24 is greater than the hardness of the signal line 22.

[0040] In actual application, since the hardness of the pin 24 is greater than that of the signal line 22, the pin 24 is less likely to deform than the signal line 22. In this way, after the pin 24 is connected to the electrical connection component, it can effectively prevent the pin 24 from being deformed and short-circuited with the surrounding conductive components, thereby improving the safety of the temperature detector 2.

[0041] In addition, the pin 24 has a relatively large hardness, and can be plugged into and matched with a corresponding electrical connection component in a device such as a controller, thereby improving the ease of use of the temperature detector 2.

[0042] In addition, the cross-section of the lead wire can be circular, elliptical, rectangular or other multiple deformations, and the lead wire can be straight or curved or bent. The cross-section of the lead wire can be circular, elliptical, rectangular or other multiple deformations, and the lead wire can be straight or curved or bent.

[0043] It should be understood that in other embodiments, the signal line 22 may only have a lead 23 but not a pin 24. In this case, the lead 23 may be electrically connected to an electrical connection component of a controller, etc., thereby achieving electrical connection between the signal line 22 and the electrical connection component.

[0044] 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 that are arranged opposite to each other; a mounting hole 33 is provided on the first surface 31, and the mounting hole 33 extends toward the second surface 32; the temperature sensing portion 21 is located in the mounting hole 33; one end of the signal line 22 is located in the mounting hole 33 and connected to the temperature sensing portion 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 temperature sensing portion 21 and the signal line 22 can be shielded and protected by the insulating connector 3 to prevent them from being damaged by collision with foreign objects, thereby increasing the service life of the temperature detector 2.

[0045] exist Figure 1 In the orientation shown, the second direction is parallel to the Z-axis.

[0046] In addition, the temperature sensing portion 21 and the portion of the signal line 22 located in the mounting hole 33 can be shielded by the insulating connector 3 to be separated from the wiring terminal 1. The portion of the signal line 22 extending out of the mounting hole 33 (this portion is defined as the first portion) is located outside the insulating connector 3. Since the first portion is the end of the signal line 22 away from the temperature sensing portion 21, this method will result in a larger spacing between the first portion and the wiring terminal 1. In this way, there is no need to set an insulating shielding structure between the first portion and the wiring terminal 1 to ensure the electrical isolation effect between the two.

[0047] In addition, when a certain component is mentioned in this article as being located in a certain hole, it may mean that the entire component is located in the hole, or only a portion of the component is located in the hole.

[0048] like Figure 4 and Figure 7 As shown, in one embodiment, in the second direction, the mounting hole 33 includes 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 arranged on the bottom surface of the first hole 331 and penetrates to the second surface 32; the pin 24 includes a first connecting portion 25 and a second connecting portion 26 that are electrically connected; the first connecting portion 25 extends along the first direction, and 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 in the first hole 331; the second connecting portion 26 extends from the second hole 332 to the outside of the mounting hole 33.

[0049] The first hole 331 is a blind hole. In the first direction, the size of the first hole 331 is larger than the size of the second hole 332. The first connecting portion 25 may be in contact with the bottom surface of the first hole 331.

[0050] This arrangement can make the temperature detector 2 installed in the installation hole 33 more stable.

[0051] In one embodiment, the shape and size of the cross section of the second hole 332 may match the cross section of the second connection portion 26, wherein the cross sections of the two are perpendicular to the second direction. For example, the second hole 332 may be a circular hole, in which case the second connection portion 26 may be a cylinder, and the diameter of the second hole 332 is equal to, slightly greater than, or slightly less than the diameter of the second connection portion 26. For another example, the second hole 332 may be a rectangular hole, in which case the second connection portion 26 may be a rectangular parallelepiped structure, and the thickness of the second hole 332 in the first direction is equal to, slightly greater than, or slightly less than the thickness of the second connection 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 less than the width of the second connection 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 connection portion 26 in the second direction.

[0052] 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 perpendicular to each other. Figure 4 and Figure 7 In the directions shown, the third direction is parallel to the Y-axis.

[0053] In addition, when there are two signal lines 22, the two signal lines 22 may be arranged at intervals along the third direction. Figure 6 and Figure 7 As shown, in one embodiment, a limiting structure 34 is provided on the bottom surface of the first hole 331, and the limiting structure 34 is used to limit the position of the first connection part 25 relative to the insulating connector 3 in the third direction. In this way, the stability of the connection of the signal line 22 on the insulating connector 3 can be further improved. Among them, the limiting structure 34 includes a plurality of limiting blocks 341, and in the third direction, each limiting block 341 is respectively located on both sides of the first connection part 25, and in the third direction, the two sides of the first connection part 25 can respectively contact the corresponding limiting blocks 341, so that the position of the signal line 22 in the third direction can be limited. "Multiple" means greater than or equal to two, and the word "multiple" has the same meaning in each embodiment, which will not be repeated in the following text.

[0054] In addition, after assembly, the first connecting portion 25 may be in contact with the bottom surface of the first hole 331 , so that the position of the signal line 22 in the second direction can be limited, and installation of the temperature detector 2 on the insulating connector 3 is facilitated.

[0055] It should be understood that when the number of the signal lines 22 is two, in the third direction, both sides of the two signal lines may abut against the limit block 341 .

[0056] exist Figure 6In the example shown, there are three limit blocks 341 , which are arranged at intervals along the third direction, and the signal line 22 is arranged between two adjacent limit blocks 341 .

[0057] like Figure 7 As shown, in one embodiment, the mounting hole 33 also includes a third hole 333, which is arranged on the bottom surface of the first hole 331 and is spaced apart from 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 portion 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 portion 21 and the signal line 22 is located in the third hole 333.

[0058] Among them, the temperature sensing portion 21 is opposite to the third hole 333 in the second direction, which may mean that: at least a portion of the temperature sensing portion 21 is located in the first hole 331, and in an orthographic projection of a plane perpendicular to the second direction, the projection of the temperature sensing portion 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 overlap.

[0059] The signal line 22 is opposite to the third hole 333 in the second direction, which may mean that at least a portion of the signal line 22 is located in 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.

[0060] The third hole 333 is provided to avoid the temperature sensing portion 21 and the signal line 22 , so that the two can be conveniently installed in the installation hole 33 .

[0061] In addition, the third hole 333 may be a blind hole that does not penetrate to the second surface 32 ; or, the third hole 333 may be a through hole that penetrates to the second surface 32 .

[0062] When the signal line 22 includes the lead 23 and the pin 24, the pin 24 actually extends out of the mounting hole 33. At this time, the pin 24 is located in the second hole 332 and extends the insulating connector 3 from the second hole 332. At the same time, in this embodiment, the first connection portion 25 and the second connection portion 26 are both part of the structure of the pin 24, that is, the pin 24 actually includes the first connection portion 25 and the second connection portion 26, and at this time, the lead 23 is located in the first hole 331, and at least one of the temperature sensing portion 21 and the lead 23 is opposite to the third hole 333 in the second direction; and / or, at least one of the temperature sensing portion 21 and the lead 23 is located in the third hole 333.

[0063] Among them, the lead 23 is opposite to the third hole 333 in the second direction, which may mean that: at least a portion of the lead 23 is located in the first hole 331, and in the 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.

[0064] When the signal line 22 includes the lead 23 but does not include the pin, the lead 23 is actually located in the second hole 332 and extends out of the mounting hole 33 from the second hole 332. At the same time, in this embodiment, the first connection portion 25 and the second connection portion 26 are both part of the structure of the lead 23, that is, the lead 23 actually includes the first connection portion 25 and the second connection portion 26.

[0065] like Figure 5 and Figure 7 As shown, in one embodiment, a notch 35 is provided on the first surface 31; in the 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 the third direction, the notch 35 completely penetrates the insulating connector 3; in the second direction, the notch 35 is spaced from the bottom surface of the first hole 331, that is, it does not penetrate to the bottom surface of the first hole 331. In addition, in the first direction, both the insulating connector 3 and the mounting hole 33 have a portion located between the notch 35 and the terminal connection area.

[0066] like Figure 1 As shown, in one embodiment, the connector 10 further includes an insulating filler 4 , which is filled in the mounting hole 33 and covers the temperature sensing portion 21 , the signal line 22 and the pin 24 .

[0067] The insulating filler 4 can prevent the temperature sensing portion 21 and the signal line 22 from shaking in the mounting hole 33 and from deforming the signal line 22, so that the temperature sensing portion 21 and the signal line 22 can be kept in a fixed position, thereby improving the stability of temperature detection of the terminal 1.

[0068] The insulating filler 4 may be made of epoxy resin or the like.

[0069] In addition, the insulating filler 4 may be filled in at least one of the first hole 331, the second hole 332, and the third hole 333. The insulating filler 4 may completely fill the mounting hole 33, or may only fill a portion of the mounting hole 33. For example, the insulating filler 4 may completely fill any one of the first hole 331, the second hole 332, and the third hole 333, or may only fill a portion of any one of the first hole 331, the second hole 332, and the third hole 333.

[0070] Furthermore, the insulating filler 4 covering the temperature sensing portion 21 may mean that the insulating filler 4 completely covers the temperature sensing portion 21 , or may mean that the insulating filler 4 covers a portion of the temperature sensing portion 21 .

[0071] The insulating filler 4 covers the signal line 22 , which may mean that the insulating filler 4 covers a portion of the signal line 22 .

[0072] When the signal line 22 includes a lead 23 and a pin 24 , the insulating filler 4 covers the lead 23 , and / or the insulating filler 4 covers the pin 24 .

[0073] The insulating filler 4 covers the lead 23, which may mean that the insulating filler 4 completely covers the lead 23, or may mean that the insulating filler 4 covers a portion of the lead 23; The insulating filler 4 covers the pin 24 , which may mean that the insulating filler 4 covers a portion of the pin 24 .

[0074] In one embodiment, two opposite ends of the connection terminal 1 are used to connect the solar panel and the inverter, respectively. Specifically, in the first direction, two opposite ends of the connection terminal 1 are used to connect the solar panel and the inverter, respectively.

[0075] In one embodiment, the connection terminal 1 and the insulating connector 3 are detachably connected, so that when one of them is damaged, only the damaged one needs to be replaced, thereby reducing maintenance costs; alternatively, the connection terminal 1 and the insulating connector 3 are an integral structure, for example, when the insulating connector 3 is plastic, the insulating connector 3 and the connection terminal 1 can be integrally formed by injection molding.

[0076] It should be understood that when the wiring terminal 1 and the insulating connector 3 are an integral structure, the wiring terminal 1 and the insulating connector 3 are not detachable.

[0077] In other embodiments, when the wiring terminal 1 and the insulating connector 3 are not detachable, the wiring terminal 1 and the insulating connector 3 may also be separately arranged, but they cannot be detached after being connected.
