Detailed implementation manners

[0033] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Next, in conjunction with Figures 1-5 , the connector provided in the embodiment of the present utility model will be described.

[0035] Specifically, the connector includes a base 100, a first conductive member 210, and a second conductive member 220.

[0036] Among them, the first conductive member 210 and the second conductive member 220 are both disposed on the base 100. One ends of the first conductive member 210 and the second conductive member 220 are respectively connected to a power supply device. For example, one end of the first conductive member 210 is connected to the positive electrode of the battery, and one end of the second conductive member 220 is connected to the negative electrode of the battery. The other ends of the first conductive member 210 and the second conductive member 220 are respectively connected to an electrical device. For example, the other ends of the first conductive member 210 and the second conductive member 220 are respectively connected to a vehicle, so as to form a complete current loop among the battery, the first conductive member 210, the vehicle, and the second conductive member 220. A fusing structure 300 is formed on at least one of the first conductive member 210 and the second conductive member 220. When the fusing structure 300 does not reach the temperature threshold, the form of the fusing structure 300 does not change, and it is used to connect and maintain the complete current loop among the battery, the first conductive member 210, the vehicle, and the second conductive member 220. When a serious fault such as a short circuit occurs in the battery, the fusing structure 300 reaches the temperature threshold, and the fusing structure 300 is melted to actively cut off the current loop, ensuring the safety of the battery pack.

[0037] In some embodiments, the fusing structure 300 is formed on the first conductive member 210 connected to the positive electrode of the battery.

[0038] In some embodiments, the fusing structure 300 and the first conductive member 210 are of an integral structure. For example, the fusing structure 300 is a part of the structure of the first conductive member 210 itself. By melting the fusing structure 300, the first conductive member 210 is disconnected to cut off the current loop.

[0039] In some embodiments, the fusing structure 300 is an external structure connected to the first conductive member 210. For example, the fusing structure 300 is a metal wire welded to the first conductive member 210. By melting the metal wire, the first conductive member 210 is disconnected to cut off the current loop.

[0040] By using the technical solution provided by the present utility model, a fusing structure 300 is formed on at least one of the first conductive member 210 and the second conductive member 220. The fusing structure 300 is used to connect the current loop where the first conductive member 210 and the second conductive member 220 are located, and the fusing structure 300 can be melted when the temperature it receives reaches the threshold to automatically cut off the current loop. By integrating the fusing structure 300 into the structure of the first conductive member 210 and / or the second conductive member 220 itself, and integrating the fusing structure 300 with the connector, compared with the existing connector that requires an additional fuse to be installed, the structure of the connector is simpler, and the assembly efficiency of the connector can be improved.

[0041] In some embodiments provided by the present utility model, the fusing structure 300 is a sheet-like structure and / or a wire-like structure. For example, the fusing structure 300 can be set as a relatively thin sheet-like structure, the fusing structure 300 can also be set as a relatively thin wire-like structure, or the fusing structure 300 can also be set as a structure combining a relatively thin sheet-like structure and a relatively thin wire-like structure. By setting the fusing structure 300 as a sheet-like structure or a wire-like structure, the cross-sectional area of the fusing structure 300 can be reduced, the fusing time can be shortened, so that the fusing structure 300 can be fused in time when heated. In addition, by changing the thickness or diameter of the fusing structure 300, the fusing of the fusing structure 300 at different currents can also be controlled.

[0042] In some embodiments provided by the present utility model, through holes 310 arranged at intervals are provided on the fusing structure 300, and fusing portions 320 are formed between adjacent through holes 310. Multiple fusing portions 320 can be fused simultaneously when the temperature threshold is reached. By providing the through holes 310 arranged at intervals on the fusing structure 300, a narrow connecting portion is formed between adjacent through holes 310, which is beneficial to simplifying the manufacturing process of the fusing structure 300 and reducing the processing difficulty of the fusing structure 300.

[0043] In some embodiments provided by the present utility model, an arc extinguishing chamber 400 is formed inside the base 100, and the fusing structure 300 is arranged in the arc extinguishing chamber 400. By arranging the arc extinguishing chamber 400 inside the base 100, the fusing of the fusing structure 300 occurs in the arc extinguishing chamber 400. By providing a relatively airtight environment through the arc extinguishing chamber 400, rapid arc extinguishing can be achieved, and accidents and accidents can be avoided to the greatest extent.

[0044] In some embodiments provided by the present utility model, an arc extinguishing medium is filled in the arc extinguishing chamber 400. The arc extinguishing medium can be a gas or a liquid or a solid with excellent arc extinguishing ability and insulating ability.

[0045] Preferably, the arc extinguishing medium is quartz sand. Quartz sand has high thermal conductivity and insulating properties, and has a large contact area with the arc, which is convenient for absorbing arc energy, using quartz sand to limit the expansion of the arc column and quickly cooling the arc to extinguish it.

[0046] In some embodiments provided by the utility model, the connector further includes a first terminal 510 and a second terminal 520, both of which are arranged on the base 100, one end of the first terminal 510 is connected to the first conductive member 210, and the other end of the second terminal 520 is connected to the second conductive member 220. The other ends of the first terminal 510 and the second terminal 520 are respectively connected to the electrical equipment, for example, the other ends of the first terminal 510 and the second terminal 520 are respectively connected to the vehicle, so that a complete current loop is formed between the battery, the first conductive member 210, the first terminal 510, the vehicle, the second terminal 520, and the second conductive member 220. By providing the first terminal 510 and the second terminal 520, it is convenient to connect the connector to the electrical equipment or the power supply equipment.

[0047] In some embodiments provided by the present utility model, the base 100 includes a support plate 110, a mounting shell 120 and an end plate 130. One end of the first conductive member 210 penetrates the support plate 110 and is connected to the first terminal 510, and one end of the second conductive member 220 penetrates the support plate 110 and is connected to the second terminal 520. The mounting shell 120 is arranged on a side of the support plate 110 close to the first conductive member 210 and the second conductive member 220. The end plate 130 is arranged on a side of the mounting shell 120 away from the support plate 110, and the end plate 130, the support plate 110 and the inner wall of the mounting shell 120 enclose an arc extinguishing chamber 400. The end plate 130 is provided with a through hole, and the first conductive member 210 and the second conductive member 220 penetrate the through hole and are fixed on the end plate 130. By setting the end plate 130 and the mounting shell 120, the first conductive member 210 and the second conductive member 220 can be installed at the same time as the end plate 130, which is beneficial to improving the installation efficiency. After the arc extinguishing is completed, the end plate 130 is opened to remove and replace the first conductive member 210 and the second conductive member 220 in the arc extinguishing chamber 400.

[0048] The connector provided by the utility model further includes two insulating shells 140, both of which are arranged on the side of the support plate 110 away from the first conductive member 210 and the second conductive member 220, and the insulating shell 140 is open at one end away from the support plate 110, and the first terminal 510 and the second terminal 520 are respectively arranged in one insulating shell 140. By respectively arranging the insulating shells 140 outside the first terminal 510 and the second terminal 520, it is convenient to connect with the power supply device or the power consumption device.
