[0020] Below with reference to the embodiment and the attached Figures 1 to 3 , the technical solution of the utility model is further elaborated.
[0021] Example 1
[0022] An improved multifunctional photovoltaic connector installation tool comprises: a wrench body 1 and a limit assembly 4, wherein the left end of the wrench body 1 is provided with an opening 11, wherein two groups of plug blocks 12 are symmetrically arranged in the opening 11, the right end of the wrench body 1 is provided with an opening 2 13, wherein the opening 2 13 is provided with an inner tooth 14, a positive electrode plug rod 21 with a hole is provided on the left side of the middle of the wrench body 1, and the positive electrode plug rod 21 with a hole is provided with a positive connector buckle through hole 22 on the upper and lower sides, and a negative electrode plug rod 31 with a hole is provided on the right side of the middle of the wrench body 1, wherein the negative electrode plug rod 31 with a hole is provided. Negative connector blocks 32 are provided on the upper and lower sides. The limit assembly 4 is provided with two groups. The limit assembly 4 includes symmetrically arranged elastic limit rods 41. The wrench body 1 is provided with a fixed rod 42. The elastic limit rod 41 includes a sliding rod 43, a clamping plate 44, a spring 45 and a push rod 46. The sliding rod 43 is slidably set on the fixed rod 42. The clamping plate 44 is fixed to the front end of the sliding rod 43. The push rod 46 is fixed to the inner side of the sliding rod 43. The spring 45 is sleeved on the sliding rod 44 and is located between the push rod 46 and the fixed plate 42.
[0023] like Figures 1 to 3 As shown, the working principle of the present invention is: when the negative connector needs to be separated from the positive connector, the plug-in block 12 of the wrench body 1 is inserted into the slot of the negative connector, so that the plug-in block of the positive connector in the slot is pushed out, thereby separating the negative connector from the positive connector.
[0024] When pre-tightening the negative nut of the negative connector and the negative connector body thread, the inner teeth 14 of one wrench body 1 are sleeved on the negative nut, and the sliding rods 43 on both sides of the perforated negative plug 31 of the other wrench body 1 are driven to move outward by the push rod 46 and compress the spring 45. The sliding rod 43 opens the card plate 44, which is larger than the size of the negative connector. Then, the perforated negative plug 31 is inserted into the inner hole of the negative connector and the negative connector block 32 is inserted into the guide hole of the negative connector. The push rod 46 is loosened and moved in the opposite direction under the action of the spring 45 so that the card plate 44 is clamped in the groove on the surface of the negative connector to prevent the wrench body from being accidentally pulled out. Finally, the two wrenches are rotated in opposite directions to pre-tighten the negative nut 44 and the negative connector body thread, which is convenient and efficient to use.
[0025] When the positive nut of the positive connector is pre-tightened with the positive connector main body thread, the inner teeth 14 of one wrench body 1 are sleeved on the positive nut, and the sliding rods 43 on both sides of the positive plug-in rod 21 with a hole of the other wrench body 1 are driven to move outward by the push rod 46 and compress the spring 45. The sliding rod 43 opens the card plate 44, which is larger than the size of the negative connector. The positive plug-in rod 21 with a hole is sleeved on the inner rod of the positive connector. At the same time, the positive connector buckle passes through the positive connector buckle through-hole 22, and the push rod 46 is released. Under the action of the spring 45, it moves in the opposite direction to clamp the card plate 44 in the groove on the surface of the positive connector to prevent the wrench body from being accidentally pulled out. The two wrenches are rotated in opposite directions to pre-tighten the positive nut and the positive connector main body thread, which is convenient and efficient to use.
[0026] The nuts of the positive and negative connectors of different structures can be tightened by using two identical wrenches without changing tools, which is easy to use. The negative connector and the positive connector can be quickly separated by inserting two sets of plugs in the opening of the wrench body into the slots of the negative connector, which is easy to use. In addition, the position of the elastic limit rod can be adjusted during use to prevent the wrench body from being accidentally pulled out and slipping, thereby affecting assembly.
[0027] As a further embodiment, the push rod 46 has an L-shaped cross section for easy pushing.
[0028] As a further embodiment, the perforated positive electrode insert rod 21 and the perforated negative electrode insert rod 31 are provided with racetrack holes 5. The racetrack holes 5 of the perforated positive electrode insert rod 21 more closely match the inner rod shape of the positive electrode connector, reducing the gap between them and improving the fit of the connection. The racetrack holes 5 of the perforated negative electrode insert rod 31 more closely match the inner hole shape of the negative electrode connector, reducing the gap between them and improving the fit of the connection.
[0029] As a further embodiment, the center of the clamping plate 44 of the left elastic limiting rod 41 is in the same straight line as the center of the positive electrode plug rod 21 with a hole, and the center of the clamping plate 44 of the right elastic limiting rod 41 is in the same straight line as the center of the negative electrode plug rod 31 with a hole, thereby ensuring centering and improving the accuracy of fixation.
[0030] As a further embodiment, a card slot 441 is provided inside the card plate 44 , and the card slot 441 is matched and inserted into the grooves on the surface of the positive connector and the negative connector.
[0031] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
