[0002] The new energy industry has been booming in the global market. Among them, the most important component of new energy vehicles is the battery pack that is responsible for providing power to new energy vehicles. The busbar is the artery "blood vessel" of the battery pack, responsible for carrying the current of charging and discharging. The performance of the busbar itself and the reliability of its connection with the counterpart cannot be ignored. Poor reliability can cause excessive loop resistance, affecting power output, or even cause abnormal temperature rise, causing fire and other accidents.
[0003] At present, when the busbar is subjected to overcurrent temperature rise and temperature cycle tests, bolts are often used to connect the busbar samples to form a DUT (Device Under Test). However, in order to reasonably and fully utilize the space and facilitate transportation, the spacing between the busbar samples in the DUT is designed to be small, and the heat dissipation between each other will affect the measurement accuracy; in addition, the simple connection by bolts can easily cause the DUT to loosen as a whole during transportation.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A busbar testing device comprises a tray and a connecting seat arranged on the upper end surface of the tray, wherein: the tray is provided with slide grooves arranged in an array; the connecting seat comprises a connecting column and a connecting plate, one end of the connecting column is connected to the connecting plate, and the other end is connected to the slide groove through a first fastener; a second dividing groove is provided on the connecting plate, and the second dividing groove divides the connecting plate into a plurality of installation areas, and each installation area is provided with a first installation hole for connecting a busbar sample.
[0007] As a further solution of the utility model: a first dividing groove is provided between each adjacent row of sliding grooves.
[0008] As a further solution of the present invention: the number of the second dividing grooves is at least two, and the second dividing grooves are arranged parallel to each other.
[0009] As a further solution of the utility model: the length of the second dividing groove is 80%-95% of the length of the connecting plate.
[0010] As a further solution of the utility model: it also includes an isolation column connected to the bottom of the tray, and the isolation column is made of insulating material.
[0011] As a further solution of the utility model: a second mounting hole is opened between adjacent slide grooves; the isolation column is connected to the tray by a second fastener passing through the second mounting hole.
[0012] As a further solution of the utility model: the material of the tray is bakelite; the material of the connecting column is insulating material; the material of the connecting plate is conductive metal.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The utility model solves the problem that the mutual heat conduction of busbar samples affects the test results of current temperature rise, temperature cycle, etc. By opening a plurality of second separation grooves on the connection plate, the connection plate is divided into a plurality of installation areas, which effectively limits the heat conduction between different installation areas, avoids the heat from being conducted to the adjacent busbar samples through the connection plate, and reduces the error during the overcurrent temperature rise test.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0022] See also Figure 1-3 In an embodiment of the utility model, a busbar test device includes a tray 1 and a connection seat 2 for connecting a busbar sample arranged on the upper end surface of the tray 1, wherein the tray 1 is provided with an array of slide slots 11, and the connection seat 2 includes a connection column 21 and a connection plate 22, one end of the connection column 21 is connected to the connection plate 22, and the other end is connected to the slide slot 11 through a first fastener 4; by adjusting the position of the connection column 21 in the slide slot 11 and fixing it through the first fastener 4, the longitudinal spacing between adjacent connection seats 2 can be adjusted to adapt to the measurement and installation of busbars of different sizes. Two parallel second separation grooves 221 are provided on the connection plate 22, and the two second separation grooves 221 divide the connection plate 22 into three installation areas, and each installation area is provided with first installation holes 222 of different specifications, which can match M5 self-clinching screws, M6 self-clinching screws, and M8 self-clinching screws, respectively, for compatibility with busbar samples of different installation apertures.
