[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires, usually a rope-like cable twisted together by several or several groups of wires (at least two in each group), each group of wires is insulated from each other, and often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power supply and external insulation. Before installing the cable, it is necessary to test the performance of the cable, such as transmission loss, durability and reliability. The simulation test device provides an important means for studying and testing cables. It can test the cable in a laboratory environment, simulating the actual operating environment.

[0003] The cable performance simulation test device in the prior art can often only perform a single tensile performance test, but this is far from meeting the needs of comprehensive performance inspection. In particular, the current simulation test device cannot simulate and adjust the temperature environment well, and therefore cannot test the performance of the cable in a high temperature environment. Because the electrical properties, mechanical properties and even life of the cable will be affected by temperature changes, there is a problem of inconvenience in adjusting to the high temperature environment.

[0004] The main purpose of the utility model is to provide a simulation test device for testing cable performance, which can effectively solve the problems raised in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] In order to adjust the test environment of the cable, the simulation mechanism 5 also includes a cooler 501 fixedly connected to the upper surface of the test shell 1, and the output port of the cooler 501 is fixedly connected to a connecting pipe 503, the other end of the connecting pipe 503 is fixedly connected to the inner wall of the test shell 1, and an air outlet 507 is provided on the outer surface of the test shell 1. The connecting pipe 503 can be used to cool the inside of the test shell 1, so that the hot air in the test shell 1 can be discharged from the air outlet 507. A temperature sensor 505 is fixedly connected to the side of the door panel 2 away from the plc control panel 506, and the outer surface of the temperature sensor 505 is electrically connected to the outer surface of the plc control panel 506 through a wire. The temperature sensor 505 is used to detect the temperature inside the test shell 1 and to adjust the temperature inside the test shell 1 in time.

[0025] It is worth mentioning that the temperature inside the test housing 1 can be detected by the set temperature sensor 505, and then the resistance heating rod 504 can be started. The resistance heating rod 504 can heat the inside of the test housing 1, and the high temperature resistance and service life of the cable can be evaluated by testing the performance changes of the cable body 4 in a high temperature environment for a long time. Then, the air cooler 501 is started to reduce the temperature inside the test housing 1. Under low temperature conditions, the temperature of the cable body 4 drops, which makes it easy to adjust the temperature of the cable body 4, thereby preventing the user from getting burned when taking out the heated cable.

[0026] In order to facilitate the simulation of the tensile performance of the cable, the test mechanism 3 includes a limit frame 306 fixedly connected to the inner wall of the test shell 1, and the outer surface of the limit frame 306 is slidably connected to the sliding plate 302, and the lower surface of the sliding plate 302 is fixedly connected to the detection plate 303, wherein the outer surface of the detection plate 303 is also electrically connected to the outer surface of the temperature sensor 505 through a wire, and then through the integrated detection current, voltage and resistance detection functions in the temperature sensor 505, it is convenient to detect the current, voltage and resistance of the cable body 4. This technology is a prior art. There are two groups of detection boards 303, and the other group of detection boards 303 is fixedly connected to the inner wall of the test shell 1, and the outer surfaces of the detection boards 303 are fixedly connected to the mounting frames 305. The outer surfaces of the two groups of detection boards 303 are fitted with the two ends of the cable body 4. The two groups of detection boards 303 are convenient for measuring the current and voltage of the cable body 4 during the detection process, wherein the inner side surface of the mounting frame 305 is slidably connected to the outer surface of the cable body 4, and the mounting frame The outer surface of the frame 305 is threadedly connected with a bolt 304, and the other end of the bolt 304 passes through the outer surface of the mounting frame 305 and is rotatably connected to a locking block 308. The outer surface of the locking block 308 fits the outer surface of the cable body 4. By rotating the bolt 304, the bolt 304 can drive the locking block 308 to move toward the center of the mounting frame 305, thereby facilitating the clamping of cable bodies 4 of different sizes. The testing mechanism 3 also includes a reduction motor 301 fixedly connected to the upper surface of the testing housing 1, and the output shaft of the reduction motor 301 passes through the outer surface of the testing housing 1 and is fixedly connected to a threaded rod 307, the lower end of the threaded rod 307 is rotatably connected to the inner wall of the testing housing 1, and the outer surface of the threaded rod 307 is threadedly connected to the outer surface of the sliding plate 302. By starting the reduction motor 301, the output shaft of the reduction motor 301 drives the threaded rod 307 to rotate, thereby enabling the sliding plate 302 to drive the detection plate 303 and the upper end of the cable body 4 to move upward, thereby facilitating the tensile test of the cable body 4.

[0027] It is worth mentioning that the two ends of the cable body 4 are respectively inserted into the mounting frame 305, and then the bolt 304 is rotated. The rotation of the bolt 304 drives the locking block 308 to move toward the outer surface of the cable body 4, thereby facilitating the clamping of the two ends of the cable body 4. Then, by starting the reduction motor 301, the output shaft of the reduction motor 301 drives the threaded rod 307 to rotate, and the rotation of the threaded rod 307 drives the sliding plate 302 to slide on the outer surface of the limit frame 306, thereby facilitating the tensile test of the outer surface of the cable body 4.

[0028] Working principle: The temperature inside the test housing 1 can be detected by the set temperature sensor 505, and then the resistance heating rod 504 is started. The resistance heating rod 504 can heat the inside of the test housing 1, which is convenient for detecting the performance of the cable body 4 in a high temperature environment. The high temperature resistance and service life of the cable are evaluated by testing the performance changes of the cable body 4 in a high temperature environment for a long time. Then the air cooler 501 is started. The air cooler 501 processes the external hot air into cold air and blows it into the test housing 1, thereby facilitating the reduction of the temperature inside the test housing 1, facilitating the protection of the users, and reducing the occurrence of users being scalded by the cable. By inserting the two ends of the cable body 4 into the mounting frame 305 respectively, and then rotating the bolt 304, the rotation of the bolt 304 drives the locking block 308 to move toward the outer surface of the cable body 4, thereby facilitating the clamping of the two ends of the cable body 4, and then starting the reduction motor 301, the output shaft of the reduction motor 301 drives the threaded rod 307 to rotate, and the rotation of the threaded rod 307 drives the sliding plate 302 to slide on the outer surface of the limit frame 306, thereby facilitating the tensile test of the outer surface of the cable body 4.
