[0001] This utility model relates to the technical field of connector testing devices, and in particular to a testing device for IDC terminals. Background Technology

[0002] IDC (Insulated Conductor Connector) is a method of crimping insulated or unstripped wires onto a connector. IDC terminals achieve electrical connection between the terminal and the wire by piercing the enamel coating of the wire, which consists of an outer enamel layer and an inner conductor layer. After production, IDC terminals typically undergo connection performance testing. Workers perform simulated wire connection tests on sampled IDC terminals.

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] refer to Figures 1 to 6 An IDC terminal testing device includes a testing frame 1, a tensioning assembly 2, and a bending and swinging mechanism 3. A protective shell 103 is provided on the outer side of the testing frame 1. A protective door 104 is rotatably connected to the front opening of the protective shell 103 and has a transparent observation window 105. The protective door 104 protects the testing frame 1 inside the protective shell 103. A telescopic cylinder or electric push rod can be pivotally connected between the protective door 104 and the protective shell 103 to automatically open or close the protective door 104. A terminal clamp 101 is fixedly connected to the upper part of the testing frame 1, and the terminal clamp 101 is used to clamp and position the IDC terminal 10. A movable groove 102 is provided through the testing frame 1 below the terminal clamp 101, extending along the width direction of the testing frame 1.

[0028] The tension assembly 2 includes a lifting mechanism 21 and a tension sensor 22. The lifting mechanism 21 includes a fixed platform 211, a movable platform 212, a drive rod 213, and a locking element 214. The fixed platform 211 is fixedly connected to the testing frame 1 and has a vertically extending stroke groove 202. The movable platform 212 is provided with a stroke bar 203 that is slidably connected to the stroke groove 202. The drive rod 213 passes through the stroke groove 202 and is rotatably connected to the fixed platform 211. The portion of the drive rod 213 located in the stroke groove 202 and the stroke bar 203 are engaged by a rack and pinion transmission. The drive rod 213 extends to the end of the fixed platform 211 and serves as an operating handwheel for the operator. The locking element 214 is a screw knob that passes through the travel groove 202 and is rotatably connected to the locking plate 204. The tension sensor 22 is mounted on the movable platform 212. The operator rotates the drive rod 213 to move the movable platform 212 up, down, and horizontally relative to the fixed platform 211. When the tension sensor 22 moves to the corresponding height position, the operator tightens the locking element 214 to drive the locking plate 204 to press against the travel bar 203 to lock the height position of the movable platform 212.

[0029] The tension sensor 22 is mounted on the lifting end of the lifting mechanism 21, and its height can be adjusted by the lifting mechanism 21. The sensing end of the tension sensor 22 is detachably connected to the end of the wire 11 away from the IDC terminal 10.

[0030] The bending swing mechanism 3 includes a swing mounting frame 31, a swing arm 32 mounted on the swing mounting frame 31, and a rotary drive device 33. The swing mounting frame 31 is fixedly connected to the testing frame 1. A centering frame 4 and a transmission frame 5 are spaced apart on the swing mounting frame 31. A centering disk 401 is pivotally connected to the centering frame 4. One end of the swing arm 32 is pivotally connected to the centering disk 401, so that one end of the swing arm 32 is rotatably connected to the swing mounting frame 31. The rotating end of the rotary drive device 33 is connected to the drive disk 501. Next, the rotary drive device 33 is offset from the drive disk 501. The rotary drive device 33 is a rotary motor. A synchronous transmission assembly 6 is provided between the rotating end of the rotary drive device 33 and the drive disk 501. The synchronous transmission assembly 6 includes a drive pulley 61, a driven pulley 62 and a synchronous belt 63.

[0031] A drive disc 501 is pivotally connected to the transmission frame 5. An eccentric shaft 502 is provided on the drive disc 501. A transmission groove 302 extending along the length direction passes through the swing arm 32. The eccentric shaft 502 is slidably connected in the transmission groove 302, thereby limiting the horizontal swing stroke of the swing arm 32. The other end of the swing arm 32 passes through the movable groove 102 and extends to the outside of the detection frame 1. Furthermore, a limiting slot 301 for the wire 11 to enter is provided at the other end of the swing arm 32.

[0032] A control console 106 is installed on the side of the testing frame 1. A controller 107 is installed on the control console 106. The tension sensor 22 and the rotation drive device 33 are both connected to and controlled by the controller 107. The controller 107 is a control panel, which is existing technology and will not be described in detail here. The tension sensor 22 senses the tension on the wire 11 and converts it into an electrical signal, which is then transmitted to the controller 107 for display.

[0033] When in use, the testing device connects the IDC terminal 10 to the wire 11. The terminal clamp 101 holds the IDC terminal 10 in place, and the wire 11 is located in the limiting slot 301 of the swing arm 32. The end of the wire 11 away from the IDC terminal 10 is connected to the sensing end of the tension sensor 22. The tension assembly 2 adjusts the height of the tension sensor 22 through the lifting mechanism 21 to stretch the wire 11 and make it straight. Then, the bending swing mechanism 3 drives the swing arm 32 to swing horizontally through the rotation drive device 33 to apply pressure to the wire 11 and bend it, thereby simulating the bending deformation that the wire 11 may encounter in actual use. The tension sensor 22 detects the tension generated when the wire 11 is stretched. In this process, the connection between the IDC terminal 10 and the wire 11 can be seen intuitively. There is no need to manually apply force to bend the wire 11. The device automatically realizes the pressure simulation test after the IDC terminal 10 and the wire 11 are connected, saving time and effort, improving testing efficiency and accuracy, and solving the technical problems of time-consuming and labor-intensive manual operation and difficulty in accurate measurement.

[0034] An elastic buffer 7 is provided between the sensing end of the tension sensor 22 and the end of the wire 11 away from the IDC terminal 10. A first mounting member 201 is provided at the sensing end of the tension sensor 22, and a second mounting member 8 is detachably connected to the end of the wire 11 away from the IDC terminal 10. The two ends of the elastic buffer 7 are detachably connected between the first mounting member 201 and the second mounting member 8, respectively. The elastic buffer is a tension spring structure, with hooks 701 at both ends. Both the first mounting member 201 and the second mounting member 8 have through holes 9 for the hooks 701 to insert into. When the wire 11 is bent by the horizontal swing of the swing arm 32, the elastic buffer 7 is compressed and expands to buffer the instantaneous impact force when the wire 11 is bent, ensuring continuous and reliable tension data collected by the tension sensor.

[0035] The first mounting component 201 has a columnar structure. The second mounting component 8 includes a first clamping part 81, a second clamping part 82, and a clamping fastener 83. The first clamping part 81 has a mating groove 801. The second clamping part 82 is inserted into the mating groove 801 so that the first clamping part 81 and the second clamping part 82 have a concave-convex fit. The outer wall of the second clamping part 82 and the outer wall of the first clamping part 81 fit together to form a columnar whole.

[0036] The first clamping part 81 and the second clamping part 82 are detachably connected by a clamping fastener 83. Preferably, the clamping fastener 83 is a bolt structure. The first clamping part 81 has a through-hole 802, and the second clamping part 82 has a through-hole 803. The rod of the clamping fastener 83 passes through the mounting hole 803 of the second clamping part 82, and the rod of the clamping fastener 83 is threadedly connected to the through-hole 802 of the first clamping part 81, so that the opposite sides of the first clamping part 81 and the second clamping part 82 abut against each other to clamp the wire 11. The through hole 9 of the second mounting member 8 is provided in the first clamping part 81 or the second clamping part 82. The second clamping part 82 has a V-shaped bayonet groove 804 for the wire 11 to be inserted into. The bayonet groove 804 limits the wire 11, and the V-shape of the bayonet groove 804 can be used for wires 11 of different diameters.

All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
