[0024] Example 1:

[0025] like Figure 1-8 As shown, the connectivity detection device for automotive cables provided by this utility model includes: a control box 1, a mounting platform 5, a cable positioning mechanism, and a branch tensioning mechanism;

[0026] Vertical support feet 6 are fixed at the four top corners of the lower side of the mounting platform 5; the cable positioning mechanism is installed on the rear side of the upper side of the mounting platform 5 to position the main terminals of the automotive cable 40; two longitudinally extending docking guide slots 17 are provided on the mounting platform 5; the two docking guide slots 17 are located on the left and right sides of the cable positioning mechanism respectively; multiple terminal docking mechanisms are longitudinally slidably installed on the two docking guide slots 17; the terminal docking mechanisms are used to dock with the branch terminals of the automotive cable 40 to detect the continuity of the branches of the automotive cable 40; the branch tensioning mechanism is installed on the mounting platform 5 to tension the branch cables of the automotive cable 40; a controller, a memory, and a power supply module are provided in the control box 1; the memory is electrically connected to the controller; the power supply module is used to supply power; the power supply module, the cable positioning mechanism, the automotive cable 40, and each terminal docking mechanism constitute a power circuit.

[0027] The automotive cable 40 is positioned and clamped using a cable positioning mechanism and a terminal docking mechanism. A power supply circuit is formed by the power supply module, cable positioning mechanism, automotive cable 40, and various terminal docking mechanisms. Each terminal docking mechanism detects the continuity of each branch terminal of the automotive cable 40. Workers can judge the continuity of the automotive cable 40 by observing the terminal docking mechanisms, simplifying the testing process and eliminating the need for workers to test each branch terminal individually, thus improving testing efficiency. A branch tensioning mechanism tightens each branch of the automotive cable 40, effectively improving the neatness of the mounting platform 5.

[0028] Furthermore, the upper side of the control box 1 is configured as a ramp 4 for easy observation; a display screen 3 and a button panel 2 electrically connected to the controller are installed on the ramp 4.

[0030] Furthermore, the cable positioning mechanism includes a main connector 10, a positioning U-shaped seat 8, and two L-shaped positioning seats 11; both ends of the positioning U-shaped seat 8 are fixed to the rear side of the upper side of the mounting platform 5; a main terminal positioning bolt 9 is threaded through the positioning U-shaped seat 8; a main pressing piece 13 for pressing on the main connector 10 is rotatably installed on the lower end of the main terminal positioning bolt 9; the main connector 10 is electrically connected to the power supply module and is used for mating and inserting into the main terminal of the automotive cable 40; an electric control switch is provided in the control box 1, which is connected in series between the main connector 10 and the power supply module, and the electric control switch is electrically connected to the controller; the two L-shaped positioning seats 11 are fixed relative to each other on the mounting platform 5; clearance slots 12 are provided on the opposite side edges of the L-shaped positioning seats 11.

[0031] The positioning and fixing of the main terminal of the automotive cable 40 is achieved by using the positioning U-shaped seat 8, the main terminal positioning bolt 9, the main pressing plate 13, and the two L-shaped positioning seats 11. After the main connector 10 is inserted into the main terminal of the automotive cable 40, the main terminal positioning bolt 9 is tightened so that the main pressing plate 13 presses tightly onto the main connector 10. At the same time, the two L-shaped positioning seats 11 limit the front side of the main terminal of the automotive cable 40, thereby positioning the main terminal of the automotive cable 40 and preventing the branch tensioning mechanism from pulling the main terminal of the automotive cable 40 and causing displacement when tightening the branch cable of the automotive cable 40.

By adjusting the position of the tensioning adjustment seat 15 in the tensioning adjustment slot 14, the tensioning column 16 tightens the branch cables of the automotive cable 40. Then, the tensioning column 16 is screwed on so that the lower end of the tensioning column 16 is pressed tightly against the bottom of the tensioning adjustment slot 14, ensuring the cleanliness of the mounting platform 5 and facilitating the acquisition device to acquire images of the automotive cable 40.

[0034] Furthermore, the terminal docking mechanism includes a clamping unit, a clamping moving seat 20, a docking mounting seat 33, an adapter 38, and a connector locking bolt 35;

[0037] The adapter 38 allows the terminal connection mechanism to be replaced according to different types of automotive cables, improving versatility. The mating of the movable docking seat 32 and the adjusting docking slot 31 enables the movable installation of the docking mounting seat 33, facilitating insertion and removal. Terminal blocks help form a power circuit, making it easy to add or remove terminal clamping mechanisms. Indicator lights 34 help operators determine the on / off status. The power supply module, electronic control switch, main connector 10, automotive cable 40, docking pins 39, docking springs, fixed pins 37, indicator lights 34, and terminal blocks constitute a power circuit. The controller connects the electronic control switch to energize the power circuit. If all the indicator lights 34 corresponding to the fixed pins 37 connected to the adapter on the same terminal docking mechanism are lit, it is determined that there is no abnormality in the branch terminal and branch cable of the automotive cable 40. If one or more indicator lights 34 are not lit, it is determined that there is an abnormality in the branch terminal and branch cable of the automotive cable 40. If all indicator lights 34 are not lit, the staff should first check the connection and try to manually connect and disconnect to eliminate the disconnection. If all indicator lights 34 are still not lit, it is determined that there is an abnormality in the branch terminal and branch cable of the automotive cable 40.

[0038] Furthermore, the clamping unit includes a clamping positioning seat 21, two clamping positioning rods 22, and two branch terminal clamping seats 25; the lower ends of the two clamping positioning rods 22 are respectively fixed to the two apex corners of the clamping moving seat 20 adjacent to the branch tensioning mechanism, and respectively slide through both ends of the clamping positioning seat 21; a limit plate 23 is fixed to the upper end of each of the two clamping positioning rods 22; a clamping spring 24 is sleeved on each of the two clamping positioning rods 22; the clamping spring 24 is elastically supported between the clamping positioning seat 21 and the corresponding limit plate 23, and is used to drive the clamping positioning seat 21 to press the branch terminal of the automotive cable 40 onto the clamping moving seat 20; a clamping drive groove 29 is provided on the vertical side of the clamping positioning seat 21 adjacent to the branch tensioning mechanism; the two branch terminal clamping seats 25 slide through both ends of the clamping positioning seat 21. The clamping drive screw 30 is rotatably mounted on the clamping drive slot 29. The front and rear threads of the clamping drive screw 30 have the same pitch but opposite directions, and the front and rear threads respectively thread through the two branch terminal clamping seats 25.
