DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of 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.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] The energy storage line integrated connector has two parts: male plug and female plug:

[0029] The male plug part is as follows:

[0030] like Figure 2 As shown, a plurality of plug plates 2 are evenly distributed in an annular manner at the end of the cylindrical male shell 1. The inner side of the plug plate 2 connected to one end of the male shell 1 has a fracture that reduces its width. A first electrode sheet 21 is embedded and fixed on the surface of each plug plate 2. The integrated cable connected to the male shell 1 is composed of a plurality of lines, and each first electrode sheet 21 is independently connected to a line.

[0031] like Figure 5 As shown, the axis portion of the male shell 1 is provided with a shaft frame 63 through the axial elastic sliding of a spring, the shaft frame 63 penetrates the end surface of the male shell 1 to fix the edge block 6, the end surface of the male shell 1 has a receiving groove 61 for receiving the edge block 6, the surface of the male shell 1 is provided with an L groove 65, a part of the L groove 65 is parallel to the axis of the male shell 1, and the other part of the L groove 65 extends in an arc shape along the surface of the male shell 1, the rotary handle 64 is fixedly connected to the shaft frame 63, the torsion ring 62 is sleeved on the outside of the male shell 1, the rotary handle 64 penetrates the L groove 65 and is fixedly connected to the torsion ring 62, and under normal conditions, the shaft frame 63 is subjected to the elastic force to retract the edge block 6 into the receiving groove 61;

[0032] The female plug part is as follows:

[0033] like Figure 3As shown, the end surface of the mother shell 3 is evenly distributed in an annular manner to open a plurality of slots 4, and the inner wall of each slot 4 is provided with a second electrode sheet 41, and the integrated cable connected to the mother shell 3 is also composed of a plurality of lines, and each second electrode sheet 41 is independently connected to a line;

[0034] like Figure 3 , Figure 7 As shown, the baffle plate 5 is elastically rotated at the center position of the end face of the mother shell 3 by a torsion spring, and a guide groove 51 is provided around the edge of the baffle plate 5 to align with the slot 4. The radius of the baffle plate 5 is larger than the minimum distance between the slot 4 and the axis of the mother shell 3, and the distance between the inner end of the guide groove 51 and the axis of the mother shell 3 is smaller than the minimum distance between the slot 4 and the axis of the mother shell 3. An angular groove 52 is provided at the center position of the end face of the baffle plate 5, and a spiral groove 31 is provided on the end face of the mother shell 3. A positioning column 53 is fixed on the surface of the baffle plate 5, and the positioning column 53 is inserted into the spiral groove 31 to limit the torsion angle of the baffle plate 5, so that the baffle plate 5 can be twisted to control the guide groove 51 to be aligned or misaligned with the slot 4.

[0035] like Figure 4 As shown, in the non-paired state, the baffle 5 is subjected to the elastic force so that the guide groove 51 and the slot 4 are in a misaligned state, and the ends of each plug board 2 are respectively inserted into each guide groove 51, and then the male shell 1 is rotated so that the plug board 2 drives the baffle 5 to overcome the elastic force and twist until the guide groove 51 is aligned with the slot 4, and then the plug board 2 is inserted into the slot 4. When the plug board 2 is fully inserted into the slot 4, the fracture of the plug board 2 is aligned with the guide groove 51, so that the baffle 5 is not blocked by the plug board 2 and rotates. The guide groove 51 is misaligned with the slot 4, and the edge of the baffle 5 blocks the fracture edge of the plug board 2, so that the plug board 2 cannot be pulled out of the slot 4. At this time, the first electrode sheet 21 and the second electrode sheet 41 are fitted one by one, so that all circuits are connected;

[0036] When disassembling the plug-in, hold the twist ring 62 and push the handle 64 and the shaft frame 63 along the L-slot 65 to overcome the elastic force and move axially, so that the edge block 6 is inserted into the edge groove 52, and then rotate the twist ring 62 to make the handle 64 drive the shaft frame 63 and the edge block 6 to twist, and the edge block 6 drives the baffle 5 to twist, so that the guide groove 51 is aligned with the slot 4, and the plug-in board 2 can be pulled out from the slot 4.

[0037] like Figure 8 As shown, a carrier block 42 is rotatably arranged on the inner wall of the slot 4, and a second electrode sheet 41 is arranged on the surface of the carrier block 42. The inner side surface of the carrier block 42 contacts the inner wall of the slot 4 through a spring sheet 43, so that the inner end of the carrier block 42 is tilted. When the plug-in board 2 is inserted into the slot 4, the first electrode sheet 21 is squeezed and contacted with the second electrode sheet 41, so that the circuit conduction is more stable.

[0038] like Figure 1 As shown, the end of the female shell 3 is provided with an extension portion 32 . During the plug-in operation, the extension portion 32 fits on the outside of the male shell 1 to seal and protect the connection between the male shell 1 and the female shell 3 .

[0039] like Figure 1 As shown, a positioning mark 7 is provided on the surface of the extension portion 32 and the surface of the male shell 1 to align with the positioning mark 7, so as to avoid the plug-in board 2 and the slot 4 from being inserted into the wrong position, thereby ensuring that each circuit is correctly connected.

[0040] like Figure 4 , Figure 6 As shown, a cavity 33 is opened inside the mother shell 3, and the slots 4 are distributed on the periphery of the cavity 33. A through opening 34 penetrating the cavity 33 is opened on the surface of the mother shell 3. The first electrode sheet 21 and the second electrode sheet 41 distributed in an annular shape have a large density, and heat is easily accumulated in the mother shell 3. The heat in the cavity 33 is evacuated through the through opening 34, so that the temperature in the mother shell 3 is appropriately reduced, thereby reducing the failure rate.
