[0036] Example 1. As... Figures 1-6A thermoformed isolation tray 1 includes a tray body 11 and a first elongated groove 12 disposed on the upper side of the tray body 11. Multiple second mounting grooves 13 are spaced apart on both sides of the first elongated groove 12. A temperature measuring groove 121 is disposed on the first elongated groove 12, and a first bracket 4 is mounted on the temperature measuring groove 121. The connecting components include a flexible printed circuit board 2 (FPC) and an electrical connector 3. The first elongated groove 12 mates with the flexible printed circuit board 2, the second mounting grooves 13 mate with the electrical connector 3, and the first bracket 4 mates with a temperature sensor (not shown in the figure). The flexible printed circuit board 2 is connected to the temperature sensor.
[0037] A first long groove 12 that mates with the flexible circuit board 2 and a second mounting groove that mates with the electrical connector 3 are pre-set on the blister tray 1. A first bracket 3 for mounting the temperature sensor is also provided. This facilitates the installation and integration of the flexible circuit board 2, the electrical connector 3 and the temperature sensor, meeting the needs of temperature detection as well as the needs of large-scale production and assembly.
[0038] The first elongated slot 12, the second mounting slot 13, and the temperature measuring slot 121 are each provided with a mating boss 14. The flexible circuit board 2 is mounted on the first elongated slot 12 via at least one mating boss 14. The connecting piece 36 of the electrical connector 3 is mounted on the second mounting slot 13 via at least one mating boss 14. The first bracket 4 is mounted on the temperature measuring slot 121 via at least one mating boss 14. The mating bosses 14 facilitate welding, fixing, riveting, or bonding.
[0039] like Figure 2 The second mounting groove 13 has a battery cell mounting position 16 on its back side for mounting the battery cell. After mounting, the electrodes of the battery cell are connected to the connecting piece 36 of the electrical connector 3.
[0040] like Figure 1 and Figure 5 The flexible circuit board 2 is electrically connected to the connecting piece 36 of the electrical connector 3 via the fifth connecting piece 21, such as... Figure 3 A connecting groove 122 is provided between the first long groove 12 and the second mounting groove 13 to cooperate with the fifth connecting piece 21; a connector 25 is provided at the free end of the flexible circuit board 2.
[0041] The outer side of the disk body 11 is provided with at least one second through hole 19 for removing material and achieving weight reduction. Figure 1 A flexible circuit board was removed from the middle. Figure 2-4 Two flexible circuit boards were removed.
[0042] The connecting piece 36 of the electrical connector 3 includes a first connecting piece 31, an end connecting piece 33, an intermediate connecting piece 32, and a fourth connecting piece 35. A second mounting groove 13, which mates with the first connecting piece 31, extends obliquely from one side of the first long groove 12 to the other. Figure 4 The end connecting piece 33 cooperates with one electrode of the battery cell, and the second mounting groove 13 that cooperates with the end connecting piece 33 is located outside the first long groove 12; the middle connecting piece 32 has a dividing boss 321 in the middle, and the two sides of the dividing boss 321 are respectively connected to one electrode of one battery cell and another electrode of another battery cell; the two sides of the fourth connecting piece 35 are respectively connected to the fifth connecting pieces 21 of the two flexible circuit boards 2.
[0043] An insulating component 351 is provided on the central protrusion of the fourth connecting piece 35. The insulating component 351 includes insulating powder (not shown in the figure) disposed in the central part of the fourth connecting piece 35 and insulating silicone on the outside of the insulating powder.
[0044] The temperature measuring groove 121 can be set on the bottom wall of the first long groove 12. One end of the first bracket 4 extends into the second mounting groove 13, and the connecting piece 36 is installed on the outside of the first bracket 4, which facilitates the fixing of the first bracket 4 and the transfer of temperature of the connecting piece 36 to the first bracket 4 and the temperature sensor.
[0045] Example 2. A plurality of first through holes 15 are provided at intervals on the first long groove 12. The first bracket 4 is installed on the first through holes 15. The first through holes 15 can be used for ventilation and removal of material from the disc 11, and can also provide installation space for the temperature sensor.
[0046] Example 3. (As shown) Figure 5 A mounting boss 61 is provided on one side of the disc body 11, and the connector 25 is mounted on the mounting boss 61; a crease 6 is provided between the disc body 11 and the mounting boss 61. This allows for an advantageous mounting of the connector 25, which is used to connect to downstream detection and power supply mechanisms. The flexible circuit board is used for low-voltage connections; more specifically, the flexible circuit board is used to receive temperature sampling signals and voltage / current sampling signals. The electrical connection structure of the flexible circuit board 2 is prior art and will not be described further in this invention.
[0047] Two first long grooves 12 are respectively provided on both sides of the disc body 11, and a tear 5 is provided between the two first long grooves 12; the connecting components include a first connecting component 17 and a second connecting component 18, and the first connecting component 17 and the second connecting component 18 are respectively provided on a first long groove 12 and a second mounting groove 13 on one side.
[0048] The two first long grooves 12 can be torn open through tear 5, allowing for independent installation of the connecting components. This reduces capacity / voltage, enabling mold reuse and reducing the cost of molding the disc body 11. After tearing, the original installation positions of the fourth connecting piece 35 can be filled with the two end connecting pieces 33. Multiple through holes are spaced apart on tear 5 and crease 6 to reduce the intensity of tearing or bending.
[0049] The thermoformed isolation tray of this utility model has a pre-set first elongated groove 12, a second mounting groove 13, and a temperature measuring groove 121, which facilitates the installation and assembly of connecting components and temperature sensors; through the design of two sets of first elongated grooves 12, in Figure 1 Two sets of battery cells can be installed horizontally, with each set capable of holding 16 battery cells, but this is not the only possibility.
[0050] Compared to pipe connections, flexible circuit boards can increase wiring density, achieve lightweight design, and offer better flexibility. The blister pack of this invention can be mass-produced using molds, facilitating large-scale assembly after production.
[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
