According to the capacity of a factory, if one production line produces ten thousand battery packs per day, the connector of the production line needs to be plugged and unplugged ten thousand times per day, and the loss of the connector is large.

Currently, every time the connector loss reaches a threshold value, it is necessary to replace the new connector, and some industrial connectors themselves are expensive, causing a rise in cost.

In this embodiment, optionally, the inserting portion 210 is fixedly connected to the copper bar 220, and since the inserting portion 210 is a relatively fine and small component, the inserting portion 210 is directly set to be fixedly connected to the copper bar 220 in the processing process, so as to ensure that the inserting portion and the copper bar 220 are properly connected, thereby avoiding the situation that the inserting portion 210 and the copper bar 220 are not in contact with each other due to improper operation of field workers. In the process of replacing the electric connection unit 200, the copper bar 220 is only required to be connected with the cable connector 310, the two parts are flat or flaky, the size is large, the installation and connection are convenient, and the condition of poor contact is not easy to occur.

However, with the method of recording the number of times of plugging and unplugging, a large amount of work is generated during the process of plugging and unplugging for many times. As for the method of measuring the circuit current, the change in current occurs, and a portion not meaning an abnormality must occur in the electrical connection unit 200. Therefore, the embodiment of the present application further provides a method, which can detect the operating condition of the electrical connection unit 200 on one hand and the operating state of the connector on the other hand.

Therefore, accurate and real-time judgment is realized.

It should be noted that, for the specific implementation of the temperature sensor 500, the embodiments of the present application are not limited to, and include but are not limited to, a thermistor or a thermocouple sensor, etc.

Further, as for the installation manner of the temperature sensor 500 in the housing 100, the present embodiment further provides the following preferred embodiments.

Optionally, the temperature sensor 500 is tightly attached to the copper bar 220, the temperature sensor 500 is provided with a connecting portion 510, and the connecting portion 510 is fixed to the screw hole 512 of the copper bar 220 through the second screw 511, so that the temperature sensor 500 is ensured to be tightly attached to the copper bar 220 all the time, and the temperature sensor 500 is prevented from being loose relative to the copper bar 220.

Optionally, a receiving sub-groove 111 for receiving the bolt assembly 400 is further disposed in the receiving groove 110, and the nut of the first screw 410 and the first nut 420 of the bolt assembly 400 are respectively disposed in the receiving sub-groove 111.

Further, in order to facilitate replacement of the electrical connection unit 200 in the receiving groove 110, the housing 100 includes an upper shell 101 and a lower shell 102, and the upper shell 101 and the lower shell 102 surround the receiving groove 110. Alternatively, the upper casing 101 and the lower casing 102 are respectively provided with mounting through holes 100a, the connection is achieved by a connecting rod 100b passing through the mounting through holes 100a of the upper casing 101 and the lower casing 102, one end of the connecting rod 100b is provided with a nut, the other end is provided with a thread, and the upper casing 101 and the lower casing 102 are fixed by screwing a second nut 100c with the thread.

On the basis, the embodiment of the present application further improves the insertion part 210 in the electrical connection unit 200, thereby extending the service life of the insertion part 210 and further extending the replacement cycle of replacing the electrical connection unit 200. For the purpose of understanding, the following detailed description is to be read in connection with the accompanying drawings.

Referring to fig. 5 and 6, fig. 5 is a schematic view of an electrical connection unit in an alternative connector of the electrical connection unit provided in the embodiments of the present application; fig. 6 is an exploded view of an electrical connection unit in an alternative connector of the electrical connection unit provided in the embodiments of the present application. As shown in fig. 5 and 6, the plugging portion 210 includes two symmetrically disposed conductive assemblies 211, the two conductive assemblies 211 are used for clamping a plug of an electric device from two sides, wherein each conductive assembly 211 includes a first conductive plate 2111 and a second conductive plate 2112, an end of the first conductive plate 2111 forms a first tooth portion 2111a, and an end of the second conductive plate 2112 forms a second tooth portion 2112a; the first conductive plate 2111 and the second conductive plate 2112 are stacked, and the first tooth portion 2111a and the second tooth portion 2112a are staggered with each other.

In this embodiment, the lower ends of the first conductive plate 2111 and the second conductive plate 2112 are respectively and fixedly connected to the copper bar 220, the upper ends of the first conductive plate 2111 and the second conductive plate 2112 respectively form a first tooth-shaped portion 2111a and a second tooth-shaped portion 2112a, and meanwhile, the first tooth-shaped portion 2111a and the second tooth-shaped portion 2112a are staggered with each other. When a plug is inserted into the mating portion 210, the interleaved first and second teeth 2111a, 2112a contact and grip the plug. For traditional conducting strip through the connected mode of parallel and level tip centre gripping plug, the conducting strip that this application embodiment provided passes through dentate structure centre gripping plug, and its beneficial effect includes: on the one hand, the clamping force of the tooth-shaped structure to the plug in the plugging process is smaller, so that the friction loss of the plug to the conducting strip in the plugging process is reduced. On the other hand, each tooth of the tooth structure forms an independent conductive contact respectively, so that the tooth structure can be contacted with the plug more firmly, and meanwhile, the tooth part formed after the first conductive plate 2111 and the second conductive plate 2112 are overlapped enables the contact area of the conductive plates and the plug not to be lower than that of the common conductive plates, thereby ensuring that the contact between the plug and the conductive plates is not reduced due to the reduction of clamping force. Further, the first conductive plate 2111 and the second conductive plate 2112 are respectively in contact with the plug through respective teeth, and when one of the conductive plates fails, the other conductive plate can still work normally. Therefore, the conductive sheet provided by the embodiment of the present application reduces the insertion friction between the plug and the insertion portion 210 under the condition of ensuring the contact yield, thereby reducing the use loss of the insertion portion 210 and prolonging the service life of the electrical connection unit 200.

Further, as shown in fig. 5 and 6, as a preferred implementation, an inner side of the first conductive sheet 2111 is used for contacting with a plug of an electric device, and the second conductive sheet 2112 is provided on an outer side of the first conductive sheet 2111; the second tooth portion 2112a is bent inward of the first conductive sheet 2111, so that the second tooth portion 2112a extends into the inside of the first conductive sheet 2111 through the slot of the first tooth portion 2111 a.

In this embodiment, the second tooth portion 2112a located at the outer side is bent and extends into the inner side of the first conductive plate 2111, and after the plug is inserted into the plug portion 210, the plug first contacts and presses the second tooth portion 2112a outwards, and then contacts the first tooth portion 2111a, thereby ensuring that the first tooth portion 2111a and the second tooth portion 2112a are respectively and fully contacted with the plug. Otherwise, if the plug contacts the first tooth 2111a first, and the first conductive plate 2111 is spread, the second conductive plate 2112 is far from the plug, and the second conductive plate 2112 may be in poor contact. The above-described solution shown in figures 5 and 6 overcomes this problem.

Alternatively, as shown in fig. 5 and 6, a support sheet 212 is respectively disposed at an outer side of each of the conductive members 211; the support sheet 212 is stacked outside the first conductive sheet 2111 and the second conductive sheet 2112.

In this embodiment, support plates 212 are disposed outside the first conductive plate 2111 and the second conductive plate 2112, so as to provide elasticity to the first conductive plate 2111 and the second conductive plate 2112, and prevent the first conductive plate 2111 and the second conductive plate 2112 from being deformed due to multiple times of insertion and removal. Alternatively, the conductive sheet may have a higher conductivity and wear resistance than the support sheet 212, and may be made of a copper material, such as highly conductive copper or copper-silver-titanium alloy. The support sheet 212 is more resilient than the conductive sheet, such as a stainless steel material. Through the cooperation of the first conductive sheet 2111 and the second conductive sheet 2112, the advantages of high conductivity and wear resistance are exerted, and the support sheet 212 makes up for the deficiency of the toughness of the conductive sheets, so that the conductivity, wear resistance and elasticity of the inserting part 210 are optimized through the combination of the first conductive sheet and the second conductive sheet.

It should be noted that, as for the supporting sheet 212, it only needs to be wrapped outside the conductive component 211 to achieve the purpose of supporting, and the specific structure and installation manner thereof are not limited in the embodiments of the present application. Preferably, the embodiments of the present application provide the following solutions.

Referring to fig. 5 and 6, as shown in the figure, the lower end of the supporting sheet 212 is connected to the copper bar 220, optionally, the supporting sheet 212, the second supporting sheet 212 and the first supporting sheet 212 are respectively provided with mounting holes 10, and the three are fastened to the copper bar 220 by passing through the three mounting holes 10 in sequence through the third screws 20. Further, the upper end of the support plate 212 may be provided as a flat end, or, preferably, as shown in fig. 5 and 6, the upper end of the support plate 212 is formed with a third tooth 212a, and the third tooth 212a is used to support at least one of the first tooth 2111a or the second tooth 2112 a.

In this embodiment, the upper end of the support plate 212 is also configured as a toothed end, and corresponds to a tooth portion of at least one of the first toothed portion 2111a or the second toothed portion 2112a, so as to support the first toothed portion 2111a and/or the second toothed portion 2112a and avoid deformation thereof.
