Specifically, the orthographic projection of the metal reinforcing plate 202 on the conductive bar 1 covers and is larger than the groove 13, that is, the area of the metal reinforcing plate 202 is larger than that of the groove 13, so that the groove 13 can be completely covered; the metal reinforcing plate 202 can ensure the strength of the grooved conducting bar 1; moreover, the area of the metal reinforcing plate 202 is set to be larger, so that the heat transfer capacity of the metal reinforcing plate 202 can be improved, the heat of the conductive bar 1 can be quickly transferred to the temperature collector 6, the accuracy of the temperature collector 6 is improved, and the use safety performance of the battery device is improved.

Of course, the metal reinforcing plate 202 may also be fixedly connected to the conductive bar 1 by fastening screws, and the metal reinforcing plate 202 may also be fixedly connected to the conductive bar 1 by the second insulating film 201.

Because the buffer structure 12 is arranged between two adjacent conducting strips 11, the buffer structure 12 protrudes to the side close to the single battery 71, the metal reinforcing plate 202 is arranged at the side of the conducting strip 11 close to the single battery 71, and the orthographic projection of the metal reinforcing plate 202 on the conducting strip 11 is positioned in the conducting strip 11, that is, the orthographic projection of the metal reinforcing plate 202 on the conducting strip 11 is not overlapped with the buffer structure 12; under the condition that be provided with at least three conducting strip 11 and two buffer structure 12, metal stiffening plate 202 is located between two adjacent buffer structure 12, so set up for metal stiffening plate 202 can not occupy the inside space in the direction of height of battery device, avoids metal stiffening plate 202 to influence the assembly of other devices.

In the present exemplary embodiment, a first insulating film 2 is provided on the two rows of conductive bars 1 and on the side of the signal collection plate 4 facing away from the battery pack 7, and the first insulating film 2 may include an insulating film body 22 and an insulating film connection portion 23; the insulating film body 22 covers the signal acquisition board 4 and one end of the two columns of conductive rows 1 close to the signal acquisition board 4; a plurality of notch portions are formed in the insulating film body 22, the notch portions are disposed opposite to the gap between the signal collecting plate 4 and the two rows of conductive bars 1, the insulating film connecting portion 23 is disposed in the notch portions, the insulating film connecting portion 23 covers the first surface 44 of the branch portion 42, specifically, one end of the insulating film connecting portion 23 is connected to the insulating film body 22, and the other end thereof extends into the groove 13.

At least two relief portions 21 are provided on the first insulating film 2, specifically, the relief portions 21 are provided at one end portion of the insulating film connecting portion 23 extending into the recess 13.

Temperature collector 6 is located one side that first insulating film 2 deviates from signal acquisition board 4, specifically, temperature collector 6 is located one side that an end that insulating film connecting portion 23 extends to in the recess 13 deviates from signal acquisition board 4. The temperature collector 6 can collect the temperature of the conductive bar 1, and the conductive bar 1 is connected with the battery post 711, so that the temperature collector can collect the temperature of the conductive bar 1. The temperature collector 6 can collect the temperature of the battery post 711.

Because the temperature collector 6 has two connecting pins 61, and the two connecting pins 61 are correspondingly connected with the signal collecting plate 4 through two avoiding parts 21, one temperature collector 6 needs to be matched with the two avoiding parts 21, that is, under the condition that one temperature collector 6 is arranged, the two avoiding parts 21 are arranged on the first insulating film 2; under the condition that two temperature collectors 6 are arranged, four avoidance parts 21 are arranged on the first insulating film 2, every two of the four avoidance parts 21 form a group, and one group of avoidance parts 21 is matched with one temperature collector 6. The escape portion 21 may be provided as a through hole penetrating the first insulating film 2, and in the case where the escape portion 21 is provided at an edge portion of the first insulating film 2, the escape portion 21 may be provided in a notched shape penetrating the first insulating film 2.

The two connecting pins 61 are further isolated by the first insulating film 2, when water vapor enters the connecting pins 61, the two connecting pins 61 of the temperature collector 6 can be electrolyzed to generate metal ions, the metal ions need to reach the position between the first insulating film 2 and the NTC temperature sensor through the side wall of the avoiding part 21, and then the metal ions migrate between the first insulating film 2 and the NTC temperature sensor, so that the migration path of the metal ions is increased, the metal ions are difficult to connect and conduct, the sensitivity of the temperature collector 6 to the water vapor is reduced, and the reliability of the temperature collector 6 is improved.

In the present exemplary embodiment, the thickness of the first insulating film 2 is equal to the height of the connection pins 61, so that the NTC temperature sensor is attached to the side of the first insulating film 2 away from the battery pack 7, and the migration path of the metal ions is further blocked, so that the metal ions are not connected and conducted; the sensitivity of the temperature collector 6 to water vapor is further reduced, and the reliability of the temperature collector 6 is improved.

Of course, in other exemplary embodiments of the present disclosure, the thickness of the first insulating film 2 may be slightly greater or slightly less than the height of the connection pins 61, and in the case that the thickness of the first insulating film 2 is slightly less than the height of the connection pins 61, the NTC temperature sensor may also be attached to the side of the first insulating film 2 away from the battery pack 7, so as to further block the migration path of the metal ions.

The orthographic projection of the connecting pin 61 on the signal acquisition board 4 is located on the orthographic projection of the avoiding part 21 on the signal acquisition board 4, namely the opening area of the avoiding part 21 is larger than the cross-sectional area of the connecting pin 61, so that the connecting pin 61 and the signal acquisition board 4 are convenient to weld.

In the present exemplary embodiment, the wire harness board assembly 200 may further include a protection frame 3, the protection frame 3 is disposed on a side of the first insulating film 2 away from the signal collecting board 4 and surrounds an outer periphery of the temperature collector 6, a height of the protection frame 3 is higher than a height of the temperature collector 6, that is, a distance between a side of the protection frame 3 away from the first insulating film 2 and the first insulating film 2 is a first distance H1, a distance between a side of the temperature collector 6 away from the first insulating film 2 and the first insulating film 2 is a second distance H2, and the first distance H1 is greater than or equal to the second distance H2, so that the protection frame 3 can protect the temperature collector 6.

The material of the protective frame 3 can be foam. The protection frame 3 may be provided as a rectangular frame. The protection frame 3 can protect the periphery of the temperature collector 6. Of course, in some other exemplary embodiments of the present disclosure, the material of the protection frame 3 may also be plastic, rubber, resin, or the like; the protection frame 3 may also be provided in a circular shape, an oval shape, various polygonal shapes, etc., and the shape thereof is mainly set according to the shape of the temperature collector 6 as long as the temperature collector 6 can be accommodated.

Further, pencil board component 200 can also include protection glue film 5, and in protection glue film 5 located the bearer bar 3, and cover in the one side that temperature collector 6 deviates from signal acquisition board 4, protection glue film 5 can fill up the clearance in protection frame 3 promptly, and protection glue film 5 can further play the guard action to temperature collector 6, avoids steam to enter into temperature collector 6. The material of protection glue film 5 can be insulating silica gel, and insulating silica gel still has certain elasticity, can reduce external impact force and transmit to temperature collector 6, avoids the damage that causes temperature collector 6.

Moreover, since the orthographic projection of the connecting pin 61 on the signal acquisition board 4 is positioned on the orthographic projection of the avoiding part 21 on the signal acquisition board 4, a gap is formed between the connecting pin 61 and the side wall of the avoiding part 21; the protective adhesive layer 5 can also fill the gap between the connecting pin 61 and the side wall of the avoiding part 21, so that the waterproof performance of the temperature collector 6 is further improved.

Fusion bonding is a manufacturing process and technique that joins metals or other thermoplastic materials, such as plastics, by means of heat, high temperature or high pressure. Namely, the materials of the first insulating film 2 and the second insulating film are melted and then covered on the two opposite sides of the two conductive rows 1 and the signal collecting plate 4, and then cooled and solidified to form the first insulating film 2 and the second insulating film. The arrangement is such that the first insulating film 2 and the second insulating film are completely attached to the conductive bar 1 and the signal acquisition board 4, so as to improve the connection strength between the first insulating film and the second insulating film; furthermore, when moisture enters the connection pins 61 of the temperature collector 6, the two connection pins 61 of the temperature collector 6 are electrolyzed to generate metal ions, and the metal ions cannot migrate between the first insulating film 2 and the signal collection plate 4. It is necessary to reach between the first insulating film 2 and the temperature collector 6 through the side wall of the escape portion 21 and then to migrate between the first insulating film 2 and the temperature collector 6.

In addition, as shown in fig. 5, when the temperature collector 6 needs to collect the temperature of the casing of the single battery 71, that is, when the casing of the single battery 71 is used as a device to be measured, the metal reinforcing plate 202 may be directly attached to the casing of the single battery 71, and the temperature of the casing of the single battery 71 may be transmitted to the temperature collector 6 through the metal reinforcing plate 202; the metal reinforcing plate 202 has a high heat conductivity coefficient, and the temperature of the casing of the single cell 71 can be quickly transmitted to the temperature collector 6 through the metal reinforcing plate 202, so that the temperature collector 6 can quickly detect the temperature of a device to be measured, and the accuracy of temperature collection is improved.

The first insulating film 2 may be disposed on a side of the signal acquisition board 4 away from the single battery 71, the avoiding portion 21 may be directly disposed on the insulating film body 22, and the specific structure of the avoiding portion 21 is described in detail above, and therefore, no further description is provided herein.

The protection frame 3 is still arranged at the periphery of the temperature collector 6, and the specific structure of the protection frame 3 has been described in detail above, so that the detailed description is omitted here. Can set up protection glue film 5 in protection frame 3, protection glue film 5 can avoid steam to enter into temperature collector 6.
