[0029] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] See attached Figure 1-6As shown, the battery connector supporting positive and negative insertion of the first embodiment includes: a male end and a female end that are adapted to each other, and a connection module for realizing the current mutual communication between the male end and the female end; the male end includes: an outer frame 1; a socket 2 embedded in the outer frame 1; and the female end includes: a plug 3 adapted to the socket.

In addition, the outer frame 1 is recessed with a groove 11 for the socket 2 to be embedded, and the bottom of the groove 11 is provided with a notch 12 for exposing the bottom of the socket 2, and the socket 2 can be engaged therein through the groove 11, and the bottom of the socket 2 is open when passing through the notch 12 at the bottom of the groove 11, which is convenient for inserting the connection module.

[0031] A connection module is used to realize the practical current interconnection between the plug 3 and the socket 2, and the connection module is arranged at the bottom of the outer frame 1. When the socket 2 is installed in the outer frame 1, the connection module can be plugged into the socket 2, and the plug 3 can be inserted into the socket 2, and finally connected to the connection module, so that the plug 3 can realize current transmission through the connection surface.

[0032] The socket 2, the outer frame 1 and the connection module are assembled. When a part of them is damaged, they can be repaired or replaced, making them easy to replace without purchasing new ones, thereby reducing costs.

[0033] The connection module includes: an integrated board 4 fixed to the bottom of the outer frame 1; a plurality of conductive tubes arranged at intervals on the integrated board 4, the conductive tubes are used to connect to the plug 3, and the other ends of the conductive tubes pass through the integrated board 4; a positive electrode sheet 42 embedded in the integrated board 4 and fixedly connected to the tail ends of the plurality of conductive tubes; a negative electrode sheet 43 crossing the positive electrode sheet 42 and fixedly connected to the tail ends of the plurality of conductive tubes, the negative electrode sheet 43 being arranged at intervals from the positive electrode sheet 42; and a wiring harness 44 for connecting the positive electrode sheet 42 and the negative electrode sheet 43. In this specific embodiment, the conductive cylinder includes: a cylinder body 41 fixed on the integrated board 4; a plurality of flower plates 411 extending outward from the opening of the cylinder body 41, and the plurality of flower plates 411 are distributed in a ring-shaped manner; and a movable groove 412 formed between every two flower plates 411, the flower plates 411 distributed in a ring-shaped manner can form a cylinder, and the flower plates 411 can make the opening of the cylinder body 41 active, so that the plug 3 can be tightly attached to it after being inserted and is not easy to loosen. Preferably, the flower plates 411 are arranged in an arc shape, and the flower plates 411 arranged in an arc shape can make the opening of the conductive cylinder slightly larger and narrower in the middle, thereby facilitating the insertion of the plug 3 while increasing the friction with the plug 3 and improving the stability of current transmission.

[0034] The number of conductive tubes can be changed according to the actual current that needs to be transmitted. The opening of the conductive tube is inserted into the interior of the socket 2. When the plug 3 is connected to the socket 2, the plug 3 can be inserted into the conductive tube, so that the plug 3 can realize current transmission through the conductive tube. The socket 2 is used to limit the conductive tube; the integrated board 4 is used to fix the conductive tube and integrate the conductive tube; the positive electrode sheet 42 can connect multiple conductive tubes in parallel, and the negative electrode sheet 43 can connect multiple conductive tubes in parallel, and the positive electrode sheet 42 and the negative electrode sheet 43 are cross-arranged, and the positive and negative poles can be switched, so as to realize the function of forward and reverse insertion between the plug 3 and the socket 2. When plugging forward, the positive electrode sheet 42 can be the positive pole and the negative electrode sheet 43 can be the negative pole. When plugging backward, the positive electrode sheet 42 can be the negative pole and the negative electrode sheet 43 can be the positive pole. The number of conductive tubes connected to the positive electrode sheet 42 and the negative electrode sheet 43 can be changed according to the actual situation to increase or reduce the transmission of current.

[0035] The middle of the socket 2 is recessed downward toward the plug 3 to form a slot 21. A limiting cylinder 22 with a through hole in the middle is integrally formed at the bottom of the slot 21. The limiting cylinder 22 is used for inserting the conductive cylinder. The inner wall of the limiting cylinder 22 is provided with limiting strips 23 at vertical annular intervals. The slot 21 is used for embedding the socket 2. The limiting cylinder 22 allows the conductive cylinder to be inserted therein, and the plug 3 is also inserted into the limiting cylinder 22.

[0036] The harness 44 is provided with a transmission line for electrically connecting to the conductive cylinders after grouping and electrically connecting, and the harness 44 is provided with positive and negative cables for connecting the positive electrode sheet 42 and the negative electrode sheet 43. The harness 44 can transmit the current transmitted by the conductive cylinder through the transmission line and the positive and negative cables, and then transmit it to the power demanding equipment or the power storage equipment.

[0037] The integrated board 4 is provided with an integrated cover 45 sleeved on a plurality of conductive cylinders, the integrated cover 45 is composed of a plurality of rings, and the integrated board 4 is provided with a fixture 46 for fixing the harness 44.

[0040] The battery connector can be installed in the box 5. When the battery is placed inside the box 5 through the battery rack, the battery input and output can be achieved through the battery connector, and the thin wire group 53 needs to be connected to the battery connector so that the current can be transmitted through the thin wire group 53. The thin wire group 53 can save space to the maximum extent, thereby increasing the energy density of the battery. When installing, the upper cover 51 of the box 5 can be covered on the box 5 and then fixed to the battery rack 52 by bolts, thereby completing the fixation of the box 5 and the battery rack 52. There is no need to fix the battery rack 52 before fixing the upper cover 51 and the box 5, which reduces the fastening structure and makes the installation steps simpler.

[0041] like Figure 7 As shown, the harness 44 can be optimized according to actual needs to add current conductors to replace the positive electrode 42 and the negative electrode 43 to achieve the same technical purpose, and the harness 44 changes the plug-in mode to a copper nose connection mode, which is more convenient when connecting and transporting the thin wire group 53.
