DETAILED DESCRIPTION

[0033] The following will be described in combination with the drawingsFigures 1-3 The application is further described in detail.

[0034] The application discloses a kind of photovoltaic panel junction box coil structure. Refer to Figure 1 , photovoltaic panel junction box coil structure includes first clamping piece 1, connecting piece 2 and second clamping piece 3, first clamping piece 1 and second clamping piece 3 are used for clamping cable near photovoltaic panel junction box one end and near connector one end respectively, and connecting piece 2 is used for winding cable in middle part. First clamping piece 1, connecting piece 2 and second clamping piece 3 are sequentially connected, and first clamping piece 1, connecting piece 2 and second clamping piece 3 are integrally formed in this embodiment.

[0035] First clamping piece 1 and second clamping piece 3 are provided with clamping port 4 and clamping groove 5, and clamping port 4 and clamping groove 5 are mutually penetrated, the opening width of clamping port 4 is less than the opening width of clamping groove 5, that is, after cable is clamped into clamping groove 5 through clamping port 4, it can be avoided as far as possible that cable drops out of clamping port 4, that is, cable can be positioned. When fixing cable, first, photovoltaic panel junction box is fixed, then cable is clamped into first clamping piece 1 through first clamping piece 1, then middle section is wound through connecting piece 2, then it is clamped from second clamping piece 3, then connector is connected, so that cable can be conveniently fixed, and after being fixed, it can also be conveniently released, so that the waste of cable tie is reduced, and the length of cable that needs to be stretched can be conveniently changed by changing winding turns, so that connector can be conveniently connected to different positions. The problem that cable needs to be damaged when being released can also be overcome, and the use cost is reduced.

[0036] In some embodiments, the clamping port 4 of the first clamping piece 1 and the clamping port 4 of the second clamping piece 3 are both provided at a position away from the connecting piece 2. In this embodiment, the clamping port 4 of the first clamping piece 1 is provided at the upper end surface of the first clamping piece 1 away from the connecting piece 2, and the clamping port 4 of the second clamping piece 3 is provided at the upper end surface of the second clamping piece 3 away from the connecting piece 2. When the cable is pulled towards the connecting piece 2, a misalignment can be formed between the cable and the clamping port 4, which can better avoid the phenomenon that the cable is separated from the clamping port 4.

[0037] Refer to Figure 2 In some embodiments, the opposite two side wall surfaces of the clamping port 4 are provided with first guide portions 6, and the opposite two side wall surfaces of the clamping port 4 refer to the wall surfaces of the first clamping piece 1 or the second clamping piece 3 corresponding to the clamping port 4. In this embodiment, the first guide portions 6 are integrally formed with the first clamping piece 1 and the second clamping piece 3. The distance between the first guide portions 6 of the two side wall surfaces gradually increases from one side close to the clamping groove 5 to one side away from the clamping groove 5, so that the clamping of the cable can be guided, so that the cable can be conveniently clamped into the first clamping piece 1 or the second clamping piece 3.

[0038] In some embodiments, the first limiting strip 7 is arranged on the opposite two side walls of the card interface 4. The opposite two side walls of the card interface 4 refer to the walls of the first card connector 1 or the second card connector 3 corresponding to the card interface 4, and the first limiting strip 7 is integrally formed with the first card connector 1 and the second card connector 3. The first limiting strip 7 can better limit the cable, so that the cable can be more stably placed in the first card connector 1 or the second card connector 3.

[0039] Referring again to Figure 1 In some embodiments, the photovoltaic panel junction box wire arrangement further comprises a first fixing member 8 and a second fixing member 9, and the first fixing member 8 and the second fixing member 9 are respectively connected to the first card connector 1 and the second card connector 3. In this embodiment, the first fixing member 8 and the first card connector 1, and the second fixing member 9 and the second card connector 3 are integrally formed. The first fixing member 8 and the second fixing member 9 are both provided with a fixing hole 10 and a fixing groove 11, and the opening width of the fixing hole 10 is smaller than the opening diameter of the fixing groove 11. The center axis of the fixing hole 10 and the card interface 4 are in the same plane.

[0040] In some embodiments, the distance between the fixing hole 10 of the first fixing member 8 and the card interface 4 of the first card connector 1 is greater than the distance between the fixing hole 10 of the second fixing member 9 and the card interface 4 of the second card connector 3, so that the cable can be more conveniently and stably clamped into the fixing hole 10 of the second fixing member 9 after being wound around the connecting member 2.

[0041] The cable is clamped into the fixing groove 11 through the fixing hole 10 of the first fixing member 8, then clamped into the clamping groove 5 through the card interface 4 of the first card connector 1, wound around the connecting member 2, clamped into the fixing groove 11 through the fixing hole 10 of the second fixing member 9, and then clamped into the clamping groove 5 through the card interface 4 of the second card connector 3, so that the cable is fixed. The first fixing member 8 and the second fixing member 9 can better fix the two ends of the cable, so that the photovoltaic panel junction box and the connector can be more stably connected.

[0042] Referring again to Figure 2 In some embodiments, the opposite two side walls of the fixing hole 10 are provided with a second guide portion 12, and the opposite two side walls of the fixing hole 10 refer to the walls of the first fixing member 8 or the second fixing member 9 corresponding to the fixing hole 10. The distance between the second guide portions 12 of the two side walls gradually increases from the side close to the fixing groove 11 to the side away from the fixing groove 11. When the cable is clamped along the fixing hole 10, the cable can be guided, so that the cable can be more stably clamped into the first fixing member 8 or the second fixing member 9.

[0043] In some embodiments, the second limiting strip 13 is connected to the two opposite side walls of the fixed opening 10. In the embodiment, the second limiting strip 13 is integrally formed with the first fixing member 8 and the second fixing member 9. Through the limitation of the second limiting strip 13, the cable can be more stably fixed after being clamped, so that the cable can be better protected.

[0044] With reference to Figure 3 In some embodiments, the connection between the first fixing member 8 and the first clamping member 1 and the connection between the second fixing member 9 and the second clamping member 3 are provided with inclined surfaces. Thus, the cable can be guided and buffered, so that the cable extending from the first fixing member 8 to the first clamping member 1 can be better protected.

[0045] The implementation principle of the wire arrangement structure of the photovoltaic panel junction box according to the embodiment of the application is as follows: after the photovoltaic panel junction box is fixed, the cable is clamped into the clamping groove 5 of the first clamping member 1 through the clamping port 4 of the first clamping member 1, then the cable is clamped into the clamping groove 5 of the second clamping member 3 through the clamping port 4 of the second clamping member 3, and finally the connector is connected to the connecting port. Therefore, when the cable is released, the cable only needs to be taken out from the clamping port 4 of the first clamping member 1 and the second clamping member 3 and wound off from the connecting member 2, so that the cable can be conveniently released.

[0046] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
