Description

Technical Field

[0001] This utility model relates to the field of CCS withstand voltage insulation testing technology, specifically a CCS rapid testing fixture. Background Technology

[0002] CCS (Cells Contact System), also known as wire harness board integration, is a whole composed of signal acquisition components, plastic structural parts, copper and aluminum busbars, etc., connected by processes such as hot pressing or riveting to realize the functions of high voltage series and parallel connection of battery cells, battery temperature sampling, battery cell voltage sampling, and short circuit protection of sampling lines. During the production process of CCS, it is necessary to perform withstand voltage and insulation tests.

[0003] Currently, when testing CCS, the CCS wire ends need to be inserted into the board of the testing equipment so that the testing equipment can perform withstand voltage insulation tests. However, during frequent insertion and removal, the wire ends may carry dust and impurities into the board. Therefore, after repeated insertion and removal, dust and impurities will gradually accumulate in the board. If there are too many impurities, it is easy to cause poor contact. However, due to the small internal space of the board, it is inconvenient to clean the inside of the board. Utility Model Content

[0004] The purpose of this invention is to provide a CCS rapid measurement fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CCS rapid measurement fixture, comprising a plate end housing and a cleaning assembly. A conductor is fixed inside the plate end housing. The cleaning assembly is connected to the top of the plate end housing. The cleaning assembly includes a fixing plate, an airbag, a pressure plate, an inlet one-way valve, a filter cover, an outlet one-way valve, a jet plate, and a jet groove. The fixing plate is mounted on the top of the plate end housing, and an airbag is fixed on the top surface of the fixing plate. A pressure plate is connected to the upper part of the airbag, and an inlet one-way valve is mounted on one end of the top of the pressure plate. A filter cover is provided on the upper end of the inlet one-way valve. An outlet one-way valve is connected to the bottom of the fixing plate, and an jet plate is connected to the lower end of the outlet one-way valve through a pipe. A jet groove is provided on one side of the jet plate.

[0006] Furthermore, the jet plate has a hollow structure and is fixedly connected to the end shell of the plate.

[0007] Furthermore, telescopic columns are fixed at both ends of the top of the fixed plate, and a return spring is sleeved on the outer side of the telescopic columns.

[0008] Furthermore, the telescopic column is fixedly connected to the pressure plate, and the pressure plate abuts against the return spring.

[0009] Furthermore, a limiting strip is fixed to the top of the pressure plate, and the cross-section of the limiting strip is an isosceles trapezoid.

[0010] Furthermore, a baffle is provided at the end of the limiting strip, and the baffle is fixedly connected to the pressure plate.

[0011] Furthermore, a retaining plate is slidably connected to the outer side of the limiting strip, and the retaining plate is C-shaped.

[0012] Furthermore, a slot is provided on one side of the plate end housing, and the slot is L-shaped.

[0013] This utility model provides a rapid CCS measurement fixture, which has the following beneficial effects:

[0014] 1. This utility model, through the design of the cleaning component, allows for easy cleaning of the inside of the board end housing during use. Simply press the airbag to allow the internal air to enter the jet plate through the exhaust one-way valve and blow it towards the surface of the conductor from the jet groove. This strong airflow blows out impurities and dust from inside the board end housing, improving the efficiency of conductor cleaning and facilitating subsequent rapid testing. After releasing the airbag, the return spring pushes the pressure plate upward to reset under the limit of the telescopic column and the fixed plate. At this time, external air is filtered through the filter cover and replenished into the airbag through the intake one-way valve, allowing for reuse and improving the convenience of maintenance.

[0015] 2. This utility model, through the setting of the card plate and the card slot, allows the card plate to be pressed down when the cleaning component is not in use, causing it to move from the opening of the card slot to the bottom. Then, the card plate can be moved away from the baffle along the length of the limiting strip, so that the card slot can limit the vertical direction of the card plate, thereby locking the height of the pressure plate. Therefore, when the cleaning component is not in use, the airbag can be contracted, thereby reducing the overall space occupied and preventing accidental shaking. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2 As shown, a CCS rapid measurement fixture includes a plate end housing 1 and a cleaning assembly 3. A conductor 2 is fixed inside the plate end housing 1. The cleaning assembly 3 is connected to the top of the plate end housing 1. The cleaning assembly 3 includes a fixing plate 301, an airbag 302, a pressure plate 303, an inlet one-way valve 304, a filter cover 305, an outlet one-way valve 306, a jet plate 307, and a jet groove 308. The fixing plate 301 is placed on the top of the plate end housing 1, and the airbag 302 is fixed on the top surface of the fixing plate 301. The pressure plate 303 is connected to the upper part of the airbag 302, and the inlet one-way valve 304 is placed at one end of the top of the pressure plate 303. The filter cover 305 is provided at the upper end of the inlet one-way valve 304. The filter cover 305 filters out dust and impurities in the air. The outlet one-way valve 306 is connected to the bottom of the fixing plate 301, and the lower end of the outlet one-way valve 306 is connected to a jet groove through a pipe. The plate 307 has a jet groove 308 on one side. The jet plate 307 has a hollow structure and is fixedly connected to the plate end housing 1. Pressing the airbag 302 allows the internal air to enter the jet plate 307 through the exhaust one-way valve 306 and blow it onto the surface of the conductor 2 from the jet groove 308. This allows the strong airflow to blow out impurities and dust from the inside of the plate end housing 1, thus improving the efficiency of cleaning the conductor 2. The top two ends of the fixed plate 301 are fixed with telescopic columns 4, and the outside of the telescopic columns 4 is fitted with a return spring 5. The telescopic columns 4 are fixedly connected to the pressure plate 303, and the pressure plate 303 abuts against the return spring 5. After releasing, the return spring 5 will push the pressure plate 303 to move upward and reset under the limit of the telescopic columns 4 and the fixed plate 301. At this time, the external air will be replenished into the airbag 302 from the intake one-way valve 304.

[0022] like Figure 1 and Figure 3As shown, a limiting strip 6 is fixed to the top of the pressure plate 303, and the cross-section of the limiting strip 6 is an isosceles trapezoid. A baffle 7 is provided at the end of the limiting strip 6, and the baffle 7 is fixedly connected to the pressure plate 303. A locking plate 8 is slidably connected to the outside of the limiting strip 6, and the locking plate 8 is C-shaped. The limiting strip 6 will limit and guide the locking plate 8, while the baffle 7 will restrict the movement path of the locking plate 8. A locking groove 9 is provided on one side of the plate end housing 1, and the locking groove 9 is L-shaped. Pressing the pressure plate 303 will drive the locking plate 8 to move down, so that it moves from the opening of the locking groove 9 to the bottom. Then, the locking plate 8 can be moved away from the baffle 7 along the length direction of the limiting strip 6, so that the locking groove 9 can limit the vertical direction of the locking plate 8, thereby locking the height of the pressure plate 303.

[0023] In summary, this CCS rapid measurement fixture, when used, should first be based on... Figure 1 , Figure 2 and Figure 3 The structure shown allows for the following steps before testing: First, press the pressure plate 303 to move the clamping plate 8 downwards, allowing it to move from the opening of the clamping slot 9 to the bottom. Then, move the clamping plate 8 away from the baffle 7 along the length of the limiting strip 6. This allows the clamping slot 9 to limit the vertical direction of the clamping plate 8, thereby locking the height of the pressure plate 303. Therefore, when the cleaning component 3 is not used, the overall space occupied can be reduced. Then, when it is necessary to clean the inside of the plate end housing 1, simply push the clamping plate 8 to make it fit against the baffle 7. The return spring 5 will then be engaged with the telescopic column 4 and the fixed... When the fixed plate 301 is in the limit position, the pressure plate 303 is pushed upward to reset. At this time, the external air will be filtered by the filter cover 305 and then replenished into the air bag 302 through the air inlet one-way valve 304. Finally, by simply pressing the air bag 302, the internal air can enter the jet plate 307 through the air outlet one-way valve 306 and be blown onto the surface of the conductor 2 from the jet groove 308. This allows the strong airflow to blow out impurities and dust from the inside of the plate end housing 1, thereby improving the efficiency of cleaning the conductor 2 and facilitating the subsequent rapid determination of the withstand voltage insulation performance of CCS using equipment.
