Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, specifically a general-purpose tooling for testing the pull-out force of ECU connectors. Background Technology

[0002] During the development of the upper cover part of the electronic control unit (ECU) and in the EPS DVP experimental verification specifications of the vehicle manufacturer, it is necessary to ensure the electrical connection of the device power supply and CAN connector mating terminal of the upper cover part. This requires testing the number of plug-in / plug-out cycles and the insertion force.

[0003] In order to quickly respond to vehicle manufacturers' requirements for connector insertion force testing, a tooling that can accurately and efficiently test pull-out force is needed for standardized quantitative testing of product insertion and pull-out force, thereby reducing the risk to component performance.

[0004] Currently, there are no special testing fixtures on the market suitable for this scenario. Existing general-purpose fixtures are not suitable for clamping the test sample. The results of connector insertion and removal tests are unstable and greatly affected by the clamping position, insertion and removal position and method. They cannot be accurately used to evaluate the strength standards of connector terminals and mating ends.

[0005] Therefore, it is necessary to design a universal tooling for ECU connector pull-out force testing to solve the problems of unstable clamping and pull-out positions and low accuracy in connector insertion and removal testing. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a universal tooling for ECU connector pull-out force testing, so as to solve the problems of unstable clamping and pull-out position and low accuracy in connector insertion and removal testing.

[0007] To achieve the above objectives, this utility model is a general-purpose tooling for testing the pull-out force of ECU connectors, including a plug-in assembly, a mounting platform, a connecting rod, and a device connector. The bottom of the device connector is connected to the plug-in assembly by a connecting rod. A mounting platform is provided directly below the plug-in assembly, and the ECU connector is mounted on the mounting platform.

[0008] The plug-in assembly includes a connector, a tightening handle, a fixed clamping finger, a movable clamping finger, and a clamping finger mounting plate. The upper end of the connector has a mounting hole for connecting to the connecting rod. A fixed clamping finger is fixed at the opening of the connector. After the screw of the tightening handle passes through the connector, it connects to the movable clamping finger. The movable clamping finger and the fixed clamping finger are positioned face to face at the opening of the connector. A clamping finger mounting plate is installed on the front and rear sides of the opening of the connector. The mounting block on the side of the movable clamping finger is inserted into the oblong hole on the surface of the clamping finger mounting plate.

[0009] The upper end of the device connector is connected to the pull-out test device by a pin.

[0010] The movable and fixed clamping fingers clamp the terminals of the ECU connector.

[0011] The installation platform is mounted on a bidirectional adjustment platform.

[0012] The bidirectional adjustment platform includes an X-axis mounting plate, an X-axis adjustment mechanism, a Y-axis mounting plate, a Y-axis adjustment mechanism, and a platform mounting plate. The Y-axis mounting plate is slidably mounted on the X-axis mounting plate. The end of the X-axis adjustment mechanism is connected to the Y-axis mounting plate. The platform mounting plate is slidably mounted on the Y-axis mounting plate. The end of the Y-axis adjustment mechanism is connected to the platform mounting plate. An installation platform is mounted on the platform mounting plate.

[0013] The mounting platform has a contoured structure that matches the ECU connector.

[0014] Compared with existing technologies, this invention uses tooling to ensure the uniqueness of the ECU connector position under test, ensuring stable clamping and pulling positions and improving accuracy. It is simple to operate and unaffected by manual operation, allowing for quick and easy changeovers, thus greatly improving testing efficiency. This invention also has the advantages of simple structure and low cost. Attached Figure Description

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] See Figure 1 , Figure 2 and Figure 3 This utility model is a general tooling for testing the pull-out force of ECU connectors, including a plug-in assembly, a mounting platform, a connecting rod, and a device connector. The bottom of the device connector 5 is connected to the plug-in assembly 3 by a connecting rod 4. The mounting platform 1 is provided directly below the plug-in assembly 3, and the ECU connector 2 is mounted on the mounting platform 1.

[0021] The plug-in assembly 3 includes a connector 31, a tightening handle 32, a fixed clamping finger 33, a movable clamping finger 35, and a clamping finger mounting plate 34. The upper end of the connector 31 is provided with a mounting hole for connecting to the connecting rod 4. The fixed clamping finger 33 is fixed at the opening of the connector 31. After the screw of the tightening handle 32 passes through the connector 31, it is connected to the movable clamping finger 35. The movable clamping finger 35 and the fixed clamping finger 33 are arranged face to face at the opening of the connector 31. A clamping finger mounting plate 34 is installed on the front and rear sides of the opening of the connector 31 respectively. The mounting block on the side of the movable clamping finger 35 is inserted into the waist-shaped hole on the surface of the clamping finger mounting plate 34.

[0022] The upper end of the device connector 5 is connected to the pull-out testing device by a pin. The motor of the pull-out testing device can drive the insertion and extraction component 3 to move up and down. The pull-out force is on the same axis, which can ensure the accuracy of the pull-out force. It can be quickly clamped and tested with the movable clamp finger 35 and the fixed clamp finger 33. The control method is simple and the cost is low.

[0023] The movable clamp finger 35 and the fixed clamp finger 33 clamp the terminal 21 of the ECU connector 2.

[0024] join Figure 4 The mounting platform 1 is mounted on the bidirectional adjustment platform 6, which is located on the platform of the tensile testing equipment. The bidirectional adjustment platform 6 includes an X-axis mounting plate 63, an X-axis adjustment mechanism 61, a Y-axis mounting plate 64, a Y-axis adjustment mechanism 62, and a platform mounting plate 65. The Y-axis mounting plate 64 is slidably mounted on the X-axis mounting plate 63. The end of the X-axis adjustment mechanism 61 is connected to the Y-axis mounting plate 64. The platform mounting plate 65 is slidably mounted on the Y-axis mounting plate 64. The end of the Y-axis adjustment mechanism 62 is connected to the platform mounting plate 65. The mounting platform 1 is mounted on the platform mounting plate 65.

[0025] Mounting platform 1 has a contoured structure that matches ECU connector 2 to facilitate the installation of ECU connector 2.

[0026] The ECU connector 2 under test can be adjusted to any position by adjusting the height and front-back position of the bidirectional adjustment platform 6, and is compatible with multiple types of pull-out fixtures. After the position adjustment is completed, it can be ensured that the clamping position of the ECU connector 2 is consistent each time it is clamped. The equipment connector 5, connecting rod 4, and plug-in assembly 3 ensure the consistency of the pull-out position, making the pull-out force measurement results more accurate and stable.

[0027] In operation, the mounting platform 1 is placed on the bidirectional adjustment platform 6, and the ECU connector 2 under test is fixedly placed on the mounting platform 1. The position of the ECU connector 2 under test is adjusted by the bidirectional adjustment platform 6 to align it with the plug-in assembly 3. Under the action of the pull-out test equipment, the plug-in assembly 3 is lowered to the working height. Then, the tightening handle 32 is rotated, which moves the movable clamping finger 35 close to the fixed clamping finger 33, thereby clamping the terminal 21 of the ECU connector 2. This ensures that the plug-in assembly 3 and the ECU connector 2 are in a vertical position. The pull-out test equipment is then started, which moves the plug-in assembly 3 downward to measure the insertion force of the ECU connector 2 terminal into the connector sleeve; or it moves the plug-in assembly 3 upward to measure the pull-out force of the ECU connector 2 terminal out of the connector sleeve.

[0028] The movable clamp finger 35 and the fixed clamp finger 33 are interchangeable to adapt to different types of terminal insertion force testing; removing the movable clamp finger 35 and the fixed clamp finger 33 can also be used to measure the insertion force of mating ends of different types of connectors, and can be adapted to the testing of insertion and extraction forces of various connector terminals and mating ends.

[0029] This invention uses tooling to ensure the uniqueness of the ECU connector position under test, guaranteeing stable clamping and pulling positions and improving accuracy. It is simple to operate and unaffected by manual operation, allowing for quick and easy changeovers, thus greatly improving testing efficiency. This invention has the advantages of simple structure and low cost, and is suitable for rapid testing of connector terminal insertion sleeves and the mating and pulling forces of male and female connector ends.
