[0035] The technical solutions in the embodiments of the present application will be clearly and completely described in connection with the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0037] The present application will be further described below in connection with the drawings and specific embodiments, but not as a limitation of the present application. DETAILED DESCRIPTION

[0039] The multi-socket integrated device of the embodiment includes N groups of sockets, one positive connection conductive row 1, one negative connection conductive row 2, one positive large wire 3, one negative large wire 4, and one temperature sensing wire 6; wherein N is greater than 1.

[0040] Each group of sockets includes one positive insert pin 5-1 and one negative insert pin 5-2.

[0041] The positive insert pins 5-1 in all groups of sockets are connected in parallel through one positive connection conductive row 1.

[0042] The negative insert pins 5-2 in all groups of sockets are connected in parallel through one negative connection conductive row 2.

[0043] One end of the positive large wire 3 is electrically connected with the positive connection conductive row 1.

[0044] One end of the negative large wire 4 is electrically connected with the negative connection conductive row 2.

[0045] The temperature sensing wire 6 includes a temperature sensor and a temperature information transmission wire.

[0046] The temperature sensor can collect temperature information of the positive connection conductive row 1.

[0047] The temperature information output end of the temperature sensor is electrically connected with one end of the temperature information transmission line.

[0048] Specifically, the embodiment is a multi-socket integrated device (a plurality of groups of sockets correspond to one socket, but the plurality of sockets are not structurally independent, but are compactly combined into one).

[0049] As Figures 2-5 shown, it is a double 2+6 (2 electrodes and 6 communication interfaces) integrated socket. The wire harness inside the two 2+6 sockets is reduced by a conductive row (the positive connection conductive row 1 and the negative connection conductive row 2 can adopt a copper row), which reduces the overall volume. When applied in a battery pack, it no longer occupies the limited space inside the battery, reducing the risk of battery damage.

[0050] The temperature sensing line 6 can be a device using a thermocouple or a thermistor as a temperature sensor, and a corresponding wire as a temperature information transmission line.

[0051] The temperature sensing line 6 can be a device using a thermocouple or a thermistor as a temperature sensor, and a corresponding wire as a temperature information transmission line.

[0052] The temperature sensing line 6 can also be arranged in a separate three-level socket or a two-pole socket, directly connected with the positive needle, and the temperature of the positive needle is collected. Specific implementation method two

[0054] The embodiment is a further description of the first embodiment. In the embodiment, each group of sockets further includes a ground needle.

[0055] The other technical features of the embodiment are exactly the same as those of the first embodiment.

[0056] Specifically, each group of sockets can be combined in the form of a three-pole socket or a two-pole socket; or even a combination of a three-pole socket and a two-pole socket, without limiting the type of socket. The socket form represented by the plurality of groups of sockets in the multi-socket integrated device can be different, as long as it meets the parallel connection mode of the positive and negative poles in the first embodiment. Specific implementation method three

[0058] The embodiment is a further description of the second embodiment. In the embodiment, it further includes a communication circuit board 7 and a communication line 8; each group of sockets further includes a remote control unit;

[0059] The control signal input / output end of the remote control unit in all groups of sockets is electrically connected with one end of the communication circuit board 7 and the communication line 8.

[0060] Other technical features of the embodiment are the same as those of Embodiment Three.

[0061] Specifically, as shown in Figure 3 , 4 , the remote control unit has 6 communication ports (control signal input / output terminals) for receiving control signals transmitted by the controller or host computer and feeding back the corresponding working status to the controller or host computer.

[0062] Since the content to be protected by the present application does not include the specific functions of the remote control unit, it is not described in detail. The communication circuit board 7 (PCB) is provided with copper wires for connection with the communication ports. Specific Embodiment Four

[0064] This embodiment is a further description of Embodiment Three. In this embodiment, a socket shell 9 is further included.

[0065] The N groups of sockets, the positive connection conductive bar 1, the negative connection conductive bar 2, and the communication circuit board 7 are all fixed in the socket shell 9.

[0066] The insertion ends of the positive pins, the negative pins, and the ground pins of the sockets all face one side wall of the socket shell 9, and the side wall is provided with openings matching the positions of the insertion ends of the positive pins, the negative pins, and the ground pins.

[0067] The other ends of the positive large wires 3, the negative large wires 4, the communication wires 8, and the temperature information transmission wires all pass out of the socket shell 9.

[0068] Other technical features of the embodiment are the same as those of Embodiment Four.

[0069] Specifically, as shown in Figure 2 , 3 , 5, the external connection wire harness only needs to lead out one group of positive large wires 3, negative large wires 4, communication wires 8, and temperature information transmission wires (the number corresponds to one group of sockets). Compared with the wire harness led out by multiple sockets, the number of wire harnesses is reduced, the overall volume is reduced, the limited space inside the battery is no longer occupied, and the risk of battery failure is avoided.

[0070] And because of the reduced volume, more socket fixing points 10 can be provided, as shown in Figure 3 , 4 , there are 6 of them, which are more secure and better sealed. Specific Embodiment Five

[0072] This embodiment is a further description of Embodiments Two, Three, or Four. In this embodiment, a host computer is further included.

[0073] The other end of the communication line 8 is electrically connected with the control signal output / input end of the host computer.

[0074] The other end of the temperature information transmission line is electrically connected with the temperature information input end of the host computer.

[0075] Other technical features of the embodiment are completely same as those of the embodiments three, four or five. Specific embodiment six

[0077] The battery of the embodiment includes the multi-socket integrated device of the embodiment five, and a battery box and an electric core;

[0078] The multi-socket integrated device is fixed to the side wall of the battery box.

[0079] The other end of the positive large line 3 is electrically connected with the positive pole of the electric core.

[0080] The other end of the negative large line 4 is electrically connected with the negative pole of the electric core.

[0081] Other technical features of the embodiment are completely same as those of the embodiment six.

[0082] Specifically, since the multi-socket integrated device of the embodiment is applied on the battery, as shown in the figure, the multi-socket integrated device is arranged on the battery box cover of the battery, and the battery box cover is used as the socket shell 9. The multi-socket can play a role of hot backup, and after one is damaged, the other socket can continue to be used, so as to improve the service life of the battery; the internal wiring harness can be reduced, the heat dissipation space of the battery can be increased, and the damage risk of the internal wiring harness can be reduced.
