Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the invention in any way.

[0032] See attached document Figure 1 As shown, a photovoltaic connector wrench includes a wrench body, which is divided into different functional areas according to its function, including a connector unlocking area 100, a connector fixing area 200, and a nut mounting area 300. The connector unlocking area 100 and the nut mounting area 300 are located at opposite ends of the wrench body, and the connector fixing area 200 is located between the connector unlocking area 100 and the nut mounting area 300.

[0033] like Figure 2 As shown, the connector unlocking area 100 is provided with two pairs of unlocking forks that are not on the same plane. Each pair of unlocking forks includes two symmetrically arranged unlocking pins, thus there are a total of four pairs of opposite unlocking pins in the connector unlocking area 100. The two unlocking pins of one pair of unlocking forks are the first unlocking pins 1, and the two unlocking pins of the other pair of unlocking forks are the second unlocking pins 2. The two first unlocking pins 1 are spaced apart, and the two second unlocking pins 2 are spaced apart, thus forming a clamping groove 8 for holding the photovoltaic connector within the same pair of unlocking forks. The first and second unlocking pins located on the same side of the clamping groove 8 are perpendicular to each other, or form other specific angles as needed, such as 120°. Therefore, the two pairs of unlocking forks are not on the same plane. The unlocking forks are used to unlock the unlocking mechanism connecting the two photovoltaic connectors during the unlocking operation.

[0034] The four unlocking clamping columns in the connector unlocking area 100 have the same structure, as shown in Figures 2-4 . The unlocking clamping column includes three different structures, namely the guide section 5, the first clamping column section 6 and the second clamping column section 7. The second clamping column section 7 is fixedly connected with the wrench body, and the first clamping column section 6 is located between the guide section 5 and the second clamping column section 7. The guide section 5 is wedge-shaped, and the two sides of the width direction of the guide section 5 are respectively provided with first guide inclined surfaces 51, and the inner side of the guide section 5 is provided with a second guide inclined surface 51. The inner side of the guide section 5 refers to the side of the guide section 5 facing the clamping groove 8. The large diameter end of the guide section 5 is connected with the first clamping column section 6, and the width of the unlocking clamping column is A. Because the first clamping column section 6 and the second clamping column section 7 have different widths, the width of the first clamping column section 6 is A1, and the width of the second clamping column section 7 is A2, so A1 < A2. The distance between the two unlocking clamping columns is B. Because the first clamping column section 6 and the second clamping column section 7 have different thicknesses, the distance between the two unlocking clamping columns at the first clamping column section 6 is B1, and the distance between the two unlocking clamping columns at the second clamping column section 7 is B2, so B1 > B2. Therefore, the clamping groove 8 has different widths at different clamping column sections, which can adapt to photovoltaic connectors of different sizes.

[0035] It should be noted that the width A of the unlocking clamping column and the distance B between the two unlocking clamping columns in this embodiment are applicable to the first unlocking clamping column 1 and the second unlocking clamping column 2.

[0036] In other embodiments, in addition to the guide section, the number of clamping column sections can be adjusted according to actual conditions. When the number of clamping column sections is more than 2, the widths of the multiple clamping column sections gradually increase from the guide section to the wrench body, and the widths of the clamping grooves corresponding to the different clamping column sections gradually decrease from the guide section to the wrench body.

[0037] Continuing to refer to Figure 2 , the connector fixing area 200 is provided with at least one connector fixing hole 3 for fixing the corresponding photovoltaic connector to avoid rotation during disassembly. Therefore, as shown in Figure 4 , a rotation stopping surface 31 formed by a plurality of convex and concave structures is arranged in the connector fixing hole 3. After the photovoltaic connector is inserted into the corresponding connector fixing hole 3, it can be blocked by the rotation stopping surface 31 to avoid rotation of the photovoltaic connector around its own axis in the connector fixing hole 3. The number and size of the rotation stopping surface are matched with the adapted photovoltaic connector. In this embodiment, two connector fixing holes 3 of different shapes are provided to match different photovoltaic connectors.

[0038] Continuing to refer to Figure 2 , 4As shown in FIG. 5, the nut mounting area 300 has a nut locking sleeve 4 protruding from the wrench body plate surface, the side of the nut locking sleeve 4 is provided with an opening 43, when the nut at the tail of the photovoltaic connector is disassembled and assembled, the cable at the tail of the photovoltaic connector can enter the nut locking sleeve 4 through the opening 43, so that the nut locking sleeve 4 can be axially moved forward to be sleeved on the nut, avoiding the interference between the cable and the nut locking sleeve 4. The inner side of the nut locking sleeve 4 is provided with a plurality of convex-concave edges 44 for matching the nut to be mounted, the convex-concave edges 44 extend along the axial direction of the nut locking sleeve 4. The inner side of the nut locking sleeve 4 is divided into two sections along the axial direction, which are a first locking section 41 and a second locking section 42, the second locking section 42 is connected with the wrench body, the inner diameter of the first locking section 41 is D1, the inner diameter of the second locking section 42 is D2, and D1≥D2; the heights of the first locking section 41 and the second locking section 42 are C1 and C2 respectively.

[0039] In other embodiments, the inner side of the nut locking sleeve 4 can be divided into more sections along the axial direction, regardless of the number of sections, the sections are smoothly transitioned. And in the axial direction, the inner diameters of the plurality of sections gradually decrease in the direction close to the wrench body, so that blind operation can be performed when locking the nut, the nut locking sleeve 4 is directly sleeved on the nut until the nut is clamped with the matched section, and the wrench is operated to tighten the nut.

[0040] Further, the outer side of the nut locking sleeve 4 is also provided with a plurality of axially extending reinforcing ribs 45, the plurality of reinforcing ribs 45 are distributed in a circumferential direction, so as to strengthen the strength of the nut locking sleeve 4.

[0041] Figure 6 The operation principle of the present application for unlocking two photovoltaic connectors is given. The two photovoltaic connectors are a first connector 400 and a second connector 500, and the first connector 400 and the second connector 500 are locked and connected through the buckling of the elastic buckle 501 and the locking hole. In this embodiment, the elastic buckle 501 is arranged on the second connector 500, and two symmetrically arranged elastic buckles 501 are arranged; the locking hole is arranged on the locking part 401 of the first connector 400, and two symmetrically arranged locking holes are arranged, and each elastic buckle 501 is inserted into the corresponding locking hole for locking. Figure 6The rear of the locking part 401 is provided with an annular unlocking groove 402, and the elastic buckle 501 is located in the unlocking groove 402 after passing through the locking hole, and the inner side of the elastic buckle 501 has a certain gap with the groove bottom of the unlocking groove 402, so that the elastic buckle 501 can be extruded from the outer side of the elastic buckle 501, so that the elastic buckle 501 as a whole can be withdrawn from the unlocking hole, and the unlocking of the two photovoltaic connectors is realized. The distance between the outer sides of the two elastic buckles 501 is L1, and the width of the unlocking groove 402 is L2. When the photovoltaic connector wrench of the application is used to unlock the two photovoltaic connectors in the connected and locked state, the first unlocking clamping column 1 or the second unlocking clamping column 2 is inserted into the unlocking groove 402 of the connector until the distance B between the two unlocking clamping columns is less than L1, at this time, the two unlocking clamping columns can extrude and deform the two elastic buckles 501 inward, and the unlocking of the two photovoltaic connectors is realized. In this process, the first guide slope 51 and the second guide slope 52 can guide the insertion of the unlocking clamping column, facilitating the realization of blind insertion operation, and according to the distance between the unlocking clamping columns and the width change of the unlocking clamping column, with the deepening of the insertion, the distance between the unlocking clamping columns gradually decreases, and the width of the unlocking clamping column gradually increases, facilitating the adaptation to different connectors.

[0042] As Figure 7 , 8 shown, when installing the nut 600 at the tail of the connector, two photovoltaic connector wrenches are needed, one of which fixes the photovoltaic connector through the connector fixing hole 3, and the other tightens or loosens the nut 600 at the tail of the photovoltaic connector through the nut locking sleeve 4 of the nut installation area 300. When the nut locking sleeve 4 of the photovoltaic connector wrench of the application is matched with different nuts 600, it is sleeved on the nut 600 from the end with the larger inner diameter of the nut locking sleeve 4, and gradually matched with the nut 600 in the axial direction until the nut 600 is matched with the inner diameter of a certain section of the nut locking sleeve 4, and the nut 600 is engaged with the convex and concave edges 44 on the section. As Figure 7 shown, the small-sized nut 600 has a smaller diameter, the nut 600 is engaged with the second locking section 42 with the inner diameter D2, and the wrench is rotated along the axis of the nut 600, so that the installation of the nut 600 is completed; as Figure 8 shown, the large-sized nut 600 has a larger diameter, the nut 600 is engaged with the first locking section 41 with the inner diameter D1, and the wrench is rotated along the axis of the nut 600, so that the installation of the nut 600 is completed.

[0043] The above embodiments are only used to illustrate the technical solutions of the application but not to limit it, and those skilled in the art should understand that the specific embodiments of the application can be modified or replaced by equivalents according to the above embodiments, and any modification or equivalent replacement without departing from the spirit and scope of the application is within the protection scope of the claims.
