Technical Field

[0001] This utility model relates to the technical field of testing the connection strength of cable harness terminals, and in particular to a device for testing the connection strength of cable harness terminals. Background Technology

[0002] With the rapid development of modern industry, automotive electronics, aerospace and new energy fields, cable harnesses, as key connection components in electrical systems, have their terminal connections whose reliability directly affects the safety and stability of equipment.

[0003] Currently, in the testing of wire harness terminal connection strength, as disclosed in the prior art patent with authorization announcement number CN222258965U, a terminal connection strength testing device is provided, including a platform. One end of the platform is rotatably provided with a retaining ring. The upper end of the retaining ring is provided with a number of retaining grooves of different widths circumferentially spaced. The other end of the platform is slidably connected to a placement plate. The placement plate is provided with a wire clamping mechanism. The lower end of the platform, away from the retaining ring, is provided with a telescopic rod that drives the placement plate to move. The other end of the platform is provided with a tension gauge connected to the placement plate.

[0004] However, during use, it was found that the device's detection effect on terminal connection strength was rather limited, which reduced the accuracy and effectiveness of the detection. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cable harness terminal connection strength testing device that facilitates the testing of cable harness terminal connection strength while simultaneously detecting current continuity under different tensile forces, thereby improving the diversity and accuracy of testing.

[0006] This utility model discloses a cable harness terminal connection strength testing device, comprising a base and a groove, with the groove mounted on the base; it also includes a moving device, a power device, a plug, a handle, and clamping blocks. The side of the groove has a wire-passing groove. The groove is mounted on the base via the moving device, which is used to drive the groove horizontally and to test the tensile strength of the cable harness terminals. The plug is slidably mounted on the groove and connected to an external power source. The handle slides through the inside of the groove, with its end connected to the plug. Two sets of clamping blocks are mounted on the base and moved in opposite directions via the power device. When a cable harness terminal is placed inside the groove, the wire harness connecting the terminal passes through the groove... The cable tray extends outwards, and a power device drives two sets of clamping blocks to move closer to each other, clamping and fixing the cable harness. Then, a moving device moves the tray away from the clamping blocks, thereby performing a tensile test on the cable harness terminals and the cable harness itself, thus detecting the connection strength of the cable harness terminals. Before testing, the plug is pushed into the tray by the operating handle. After the plug is connected to the tray, the cable harness is energized. By connecting the other end of the cable harness to a current detection device, it is possible to detect the current continuity under different tensile forces while simultaneously testing the connection strength of the cable harness terminals, thus improving the diversity and accuracy of the testing.

[0007] Preferably, the power unit includes a guide groove, support members, a lead screw, a worm gear, a worm, and a handwheel. The guide groove is installed on the outer wall of the base. Both sets of support members are slidably installed on the guide groove. Two sets of clamping blocks are respectively installed on the outer walls of the two sets of support members. The lead screw is rotatably installed on the inner wall of the guide groove. The two sets of support members are screwed onto the lead screw. The worm gear is installed at the end of the lead screw. The worm is rotatably installed on the guide groove and meshes with the worm gear. The handwheel is installed at the end of the worm. The operator rotates the worm by operating the handwheel. After the worm rotates, it drives the lead screw to rotate through meshing with the worm gear. After the lead screw rotates, it drives the two sets of support members to move in opposite directions, thereby facilitating the movement of the two sets of clamping blocks to clamp and fix the wire harness.

[0008] Preferably, the moving device includes a guide rail, a first electric cylinder, and a pressure sensor. The guide rail is disposed on the outer wall of the base, and the tank is horizontally slidably mounted on the guide rail. The first electric cylinder is mounted on the outer wall of the base, and the output end of the first electric cylinder is connected to the outer wall of the tank through the pressure sensor. The pressure sensor is pushed by the extension of the moving end of the first electric cylinder, causing the pressure sensor to push the tank to move. The pressure sensor measures the pressure intensity between the first electric cylinder and the tank, thereby facilitating the measurement of the tensile strength of the cable harness terminals and realizing the detection of the connection strength of the cable harness terminals.

[0009] Preferably, it also includes a bracket, a pressing component, and a second electric cylinder. The bracket is installed on the outer wall of the tank, the pressing component is slidably installed on the bracket, and the second electric cylinder is installed on the outer wall of the bracket. The moving end of the second electric cylinder is connected to the pressing component. The pressing component is driven to move downward by the second electric cylinder, so that the pressing component presses and fixes the terminal placed in the tank, thereby improving the positional stability of the cable harness terminal during detection.

[0010] Preferably, it also includes a display, which is mounted on the outer wall of the base. The display is connected to the pressure sensor via a processor. The signal from the pressure sensor is processed by the processor and then sent to the display, so as to facilitate the display of pressure data.

[0012] Preferably, the groove is provided with a positioning groove to improve the positioning effect after the terminal is placed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The cable harness terminal is placed inside the groove, and the cable harness connecting the terminal extends out of the groove through the wire passage. A power device drives two sets of clamping blocks to move closer to each other, clamping and fixing the cable harness. Then, a moving device moves the groove away from the clamping blocks, thereby performing a tensile test between the cable harness terminal and the cable harness, thus detecting the connection strength of the cable harness terminal. Before testing, the plug is pushed into the groove by the operating handle. After the plug connects to the groove, the cable harness is energized. By connecting the other end of the cable harness to a current detection device, it is convenient to simultaneously detect the current flow under different tensile forces while testing the connection strength of the cable harness terminal, improving the diversity and accuracy of the testing.
