Technical Field

[0001] This utility model relates to the technical field of pull-out testing equipment, and in particular to a terminal pull-out force testing device. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They are used to clamp the ends of stripped wires to facilitate wire connection. As the application of terminal blocks expands, the types of terminal blocks on the market are gradually increasing, including pin terminals, Y-type terminals, etc. However, terminal blocks are generally clamped to the ends of wires by external force, which can easily lead to undervoltage, causing the terminals to frequently fall off. This results in poor contact at the wire connection point, affecting the final wiring effect. Furthermore, current technology makes it difficult to quickly test the pull-out force of different types of terminals, resulting in poor practicality. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a terminal pull-out force testing device, including a base frame 1, a fixed platform 2 on one side of the top of the base frame 1, a mounting groove 3 in the middle of the fixed platform 2, a terminal fixing seat 4 detachably installed in the mounting groove 3, a testing component 5 in the middle of the base frame 1, a guide sliding component 6 at the bottom of the testing component 5, and a winding component 7 on the top of the base frame 1 away from the fixed platform 2. By moving the locking rod 11, the terminal side of the terminal is overlapped into the fixing cavity 9 in the terminal fixing seat 4, and then the wire end of the terminal is connected to the testing component. The corresponding pull ring 52 in component 5 is used for binding, thereby enabling quick installation of the terminal block. The testing personnel drive the winding shaft 72 to wind the steel wire rope 73 by cranking the turntable 74 in the hand-cranked winding assembly 7. Then, through the corresponding pull ring 52, the tension sensor 51 is moved along the guide rail 61 to straighten the terminal block. By continuously rotating the turntable 74 to wind the steel wire rope 73, the terminal block is pulled until it is separated from the wire. Then, the tension sensor 51 detects the tension value when it is separated, which quickly realizes the detection of the pull-out force of the terminal block and improves the convenience of the equipment.

[0020] Specifically, the base frame 1 is provided with mounting feet 8 at each of its four corners. The base frame 1 is fixed to the mounting base surface by bolts passing through the mounting feet 8, thereby improving the stability of the equipment.

[0021] like Figure 3 As shown, specifically, the terminal fixing base 4 has a fixing cavity 9 on its top, and a telescopic cavity 10 on one side of the fixing cavity 9. A locking rod 11 is movable inside the telescopic cavity 10. One side of the locking rod 11 is connected to the bottom wall of the telescopic cavity 10 by several springs 12. The side of the terminal fixing base 4 has a locking hole 13 that is inserted and fitted with the locking rod 11. The side of the terminal fixing base 4 has a lever 14. By levering the locking rod 11, the springs 12 are compressed, and the fixing cavity 9 is opened, which facilitates the quick connection of the terminal side of the wiring terminal to the fixing cavity 9, thereby improving the efficiency of wiring terminal replacement and installation.

[0022] Specifically, the opening of the mounting groove 3 is symmetrically provided with elastic protrusions 15, and the terminal fixing seat 4 is provided with a groove 16 that engages with the elastic protrusions 15. By moving the lever 14 on the side of the terminal fixing seat 4, the groove 16 of the terminal fixing seat 4 can be disengaged from the elastic protrusions 15, which makes it easy to replace the corresponding terminal fixing seat 4 according to the wires of different diameters or models of wiring terminals, thereby improving the practicality of the equipment.

[0023] Specifically, the detection component 5 includes a tension sensor 51 located in the middle of the base frame 1. Pull rings 52 are connected to the output ends on both sides of the tension sensor 51. A pad block 53 is provided at the bottom of the tension sensor 51. The pull rings 52 on both sides are connected to the wires of the corresponding steel wire rope 73 and the terminal block, respectively, so as to facilitate the detection of the data value when the terminal block is pulled out by the tension sensor 51.

[0024] Specifically, the guide slide assembly 6 includes a guide rail 61 located in the middle of the base frame 1. The shim block 53 is slidably connected along the guide rail 61 via a slider 62. Buffer pads 63 are symmetrically provided at the ends of the guide rail 61. During the detection process, the slider 62 drives the tension sensor 51 to move along the guide rail 61, thereby improving the stability of the equipment. When the terminal block is pulled out, the buffer pads 63 buffer and block the slider 62, reducing the instantaneous impact force.

[0025] Specifically, the winding assembly 7 includes winding plates 71 symmetrically arranged on the side of the base frame 1 away from the fixed platform 2. The winding plates 71 on both sides are rotatably mounted on a winding shaft 72. A steel wire rope 73 is provided on the outer circular wall of the winding shaft 72. A turntable 74 is provided at one end of the winding shaft 72. The inspection personnel drive the winding shaft 72 to wind the steel wire rope 73 by manually turning the turntable 74. In the process of gradually winding, the terminal is separated from the wire, which improves the convenience of terminal pull-out force detection.

[0026] The working principle of this utility model is as follows: In use, by moving the locking lever 11, one side of the terminal of the wiring terminal is connected to the fixing cavity 9 in the terminal fixing seat 4, and then the wire end of the wiring terminal is tied to the corresponding pull ring 52, thereby realizing the quick installation of the wiring terminal. The tester drives the winding shaft 72 to wind the steel wire rope 73 by hand-cranking the turntable 74. Then, through the corresponding pull ring 52, the tension sensor 51 is driven to move along the guide rail 61 to straighten the wiring terminal. By continuously rotating the turntable 74 to wind the steel wire rope 73, the wiring terminal is pulled until the terminal is separated from the wire. Then, the tension sensor 51 detects the tension value when it is separated, which quickly realizes the detection of the pull-out force of the wiring terminal and improves the convenience of the equipment.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
