DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Please refer to Figs. 1-3 The utility model provides technical scheme: a durability test device for terminal block, including base 8, the top of base 8 is fixedly installed with slide rail 11, the top of slide rail 11 is slidably connected with first motor 12, the left side of first motor 12 is provided with control bin 13, the inside bearing of control bin 13 is connected with cam 14, the rotation shaft of cam 14 is connected with the output shaft of first motor 12, the inside bearing of cam 14 is connected with connecting rod 15, the inside of control bin 13 is slidably connected with push rod 16, connecting rod 15 and push rod 16 are bearing connected with each other, the rear side of push rod 16 is provided with detection machine 17, first motor 12 slides on slide rail 11 left and right, simultaneously drives control bin 13 to follow displacement, after reaching specified position, start first motor 12, then the output shaft drives the rotation of cam 14 in the inside of control bin 13, when cam 14 rotates, pull connecting rod 15 and drive push rod 16, which can only slide displacement forward and backward under the limitation of control bin 13, to slide displacement forward and backward, to realize the plug-in operation of simulation wire harness;

[0021] A first bracket 18 is fixedly installed on the rear side of the testing machine 17. A cylinder 20 is installed inside the first bracket 18. A testing plate 21 is installed in front of the cylinder 20. A spring 19 is welded to the rear side of the testing plate 21. The other end of the spring 19 is welded to the first bracket 18. A second bracket 22 is installed on the outer side of the testing plate 21. An insert plate 23 is installed on the rear side of the second bracket 22. When the first motor 12 drives the push rod 16 to slide back and forth, it will drive the testing machine 17 to reciprocate back and forth. When the testing machine 17 is pushed backward, the insert plate 23 will be inserted into the terminal block 6. After the fixing is completed, the testing machine 17 moves forward. When the insertion plate 23 is about to be removed, it is fixed and cannot be moved. The pulling force will pull the first bracket 18 forward, causing the air rod of the cylinder 20 to retract inward. At the same time, the spring 19 is compressed. The detection plate 21 will detect the degree of compression of the cylinder 20. If the terminal 6 can fix the insertion plate 23 normally, the cylinder 20 will retract the air rod inward by a fixed amount under a certain pulling force. Conversely, when the insertion plate 23 is pulled, it will disengage from the terminal 6. At this time, the cylinder 20 will not compress. Thus, it is determined that the terminal 6 cannot fix the insertion plate 23 normally, thereby achieving the effect of durability testing.

[0022] A support plate 9 is provided above the base 8. A fixing plate 10 is slidably connected to the right side of the support plate 9. A terminal block 6 is provided above the support plate 9. A fixing piece 24 is provided inside the terminal block 6. A screw 7 is provided above the terminal block 6. The terminal block 6 fixes the wire harness by inserting the wire harness into the fixing piece 24 and then tightening the screw 7 to fix it. Checking whether it can be fixed means whether tightening the screw 7 can fix the wire harness.

[0023] An extension frame 1 is fixedly installed on the top of the base 8. A control block 2 is slidably connected to the top of the extension frame 1. An extension device 3 is provided at the bottom of the control block 2. The control block 2 drives the extension device 3 to move left and right to the designated position for testing.
