[0060] Now, refer to Figures 1 to 3 Exemplary embodiments according to the present invention will be described in more detail below.
[0061] refer to Figure 1 This application provides a BPC box testing fixture 100, which includes a base 110, a driving device 120, and a mounting plate 130. The base 110 has a first end 101 and a second end 102 opposite to each other along a first direction D1. The base 110 has a test area 111 for supporting the BPC box 10 under test. The test area 111 is closer to the second end 102 than the first end 101. The driving device 120 is disposed on the base 110 and spaced apart from the test area 111. The driving device 120 is closer to the first end 101 than the second end 102. The mounting plate 130 is connected to the output end of the driving device 120. The driving device 120 can drive the mounting plate 130 to move closer to or away from the test area 111. The mounting plate 130 is provided with a probe 131. The side of the probe 131 closer to the test area 111 is used to mate with an interface on the BPC box 10, and the side of the probe 131 away from the test area 111 is used to connect with a testing system. The detection part 131 can be a probe or a contact, preferably a probe that penetrates the insert plate 130.
[0062] According to the BPC box testing fixture 100 of this utility model, the detection unit 131 can be connected to the relevant interface of the BPC box 10 under test in one go by the drive device 120, which greatly improves the production speed and reduces the labor intensity.
[0063] More specifically, a first fixing plate 112 is provided on the base 110, and the first fixing plate 112 is located near the first end 101. The driving device 120 is fixedly mounted on the first fixing plate 112. Preferably, the driving device 120 is constructed as a cylinder.
[0064] A guide rail assembly 113 is provided on the base 110, and the guide rail assembly 113 extends along a first direction D1. Preferably, two guide rail assemblies 113 are provided on the base 110 at intervals along a second direction D2. The second direction D2 is perpendicular to the first direction D1. Alternatively, the first direction D1 can be the front-back direction of the BPC box testing fixture 100, and the second direction D2 can be the left-right direction of the BPC box testing fixture 100.
[0065] The BPC box testing fixture 100 also includes a second fixing plate 114, which is movably mounted on the guide rail assembly 113. In other words, the guide rail assembly 113 passes through the second fixing plate 114, and the second fixing plate 114 can slide along the guide rail assembly 113. An insert plate 130 is disposed on the side of the second fixing plate 114 closest to the test area 111, and the driving end of the driving device 120 is connected to the side of the second fixing plate 114 furthest from the test area 111, so that the second fixing plate 114 can move along the first direction D1 under the action of the driving device 120. As one implementation, both the first fixing plate 112 and the fixing plate have through holes 115.
[0066] refer to Figure 1 and Figure 3 The BPC box testing fixture 100 also includes a power supply device 160, which is used to electrically connect to the BPC box 10 under test for charge-discharge testing. The power supply device 160 is preferably disposed on both sides of the second fixing plate 114 along the second direction D2, or the power supply device 160 can be disposed on the left and right sides of the second fixing plate 114. Preferably, the BPC box testing fixture 100 also includes a cover plate 150, which is connected to the edge of the base 110 along the second direction D2. Specifically, it has a top plate 151 and two side walls 152, which are connected to the left and right edges of the base 110. The top plate 151 is spaced apart from the base 110 and connected between the two side walls 152. Thus, a channel is formed between the cover plate 150 and the base 110, specifically between the top plate 151 and the base 110, extending along the first direction D1. Preferably, the first fixing plate 112 is located outside the channel, and the second fixing plate 114 is located in the channel. In other words, the power supply device 160 is also located in the channel.
[0067] The insert plate 130 is connected to the second fixed plate 114 via at least two support portions 132, thus both creating a gap between the insert plate 130 and the second fixed plate 114 and being able to stably receive the thrust from the second fixed plate 114. The side of the insert plate 130 near the second fixed plate 114 is used for wiring; cables are led out from the gap between the two and pass through the through hole 115 of the second fixed plate 114. Cables can also pass through the through hole 115 of the first fixed plate 112, thereby connecting to the testing system. Preferably, a support plate 118 is provided at the opening 117 of the first fixed plate 112, located on the side of the first fixed plate 112 near the first end 101. The support plate 118 preferably has baffles 119 extending to both sides of the through hole 115 along the second direction D2, thereby facilitating cable coiling.
[0068] refer to Figure 1 , Figure 2 and Figure 3Two limiting plates 116 are provided on the base 110, located on both sides of the test area 111 along the second direction D2, i.e., one limiting plate 116 is provided on each of the left and right sides of the test area 111. Preferably, the distance between the two limiting plates 116 matches the size of the BPC box 10. Furthermore, each limiting plate 116 has an opening 117 for signal lines to pass through. Signal transmission cables, power cables, etc., led out from the test system can be connected to the BPC box 10 through this opening 117.
[0069] In addition, the BPC box test fixture 100 also includes a control unit 140, which is connected to the drive device 120 by signal. The control unit 140 has an operating lever 141 for operation by personnel.
