[0033] See also Figure 1 , Figure 2 as well as Figure 8 In the charging pile cable drag test, the pulling and dragging conditions that the cable may suffer in daily use are usually simulated to ensure that it can withstand various stresses in actual scenarios without being damaged or affecting performance.
[0034] When testing cable samples, due to the inconsistency of cable sample sizes, the connection position needs to be fixed. The traditional connection process is to use cable ties or other fixing methods, but the later disassembly will be very troublesome, and the later connection needs to be fixed again, and the fixing method of the cable tie is not conducive to the test. Based on this, the present application provides a charging pile cable dragging test device, including a test box 1 for a dragging test, a combination part 3 arranged in the test box 1, and a second terminal 6 and a first terminal 5 installed in the test box 1 and at the combination part 3;
[0035] A driving assembly 4 is provided near the top of the inner side of the test box 1, and a combination part 3 is slidably connected to the driving assembly 4, a test sample 2 is clamped to the combination part 3, and one end of the test sample 2 is connected to the second terminal 6;
[0036] The combination includes a docking block 31, the top of which is adapted to the driving assembly 4, and is used to drive the docking block 31 to move along a preset stroke for a dragging experiment;
[0037] An installation area 32 is provided inside the docking block 31, a card block 35 is installed inside the installation area 32, and plug pins 38 are provided on both sides of the card block 35, one group of plug pins 38 is connected to the charging gun, and the other group of plug pins 38 is adapted to the wiring group;
[0038] The wiring assembly includes a circular plate 33 , and one or more wiring ports 34 are provided on the circular plate 33 for clamping with the other end of the test sample 2 .
[0039] First of all, the test box 1 is the basis of the whole system and is used for dragging experiments. The size and structure of the test box 1 should be strong enough to accommodate the drive assembly 4 and the combination part 3, and keep the test sample 2 stable. The drive assembly 4 is installed near the top of the inner side of the test box 1. This assembly is one of the key components for realizing the dragging experiment. It drives the combination part 3 to move through a sliding connection with the combination part 3, thereby applying force to the test sample 2. The combination part 3 includes a docking block 31, which is located at one end of the test sample 2 and is fixed to the drive assembly 4 by a snap-on method. An installation area 32 is provided on the inner side of the docking block 31, and a card block 35 is installed in this area. The function of the card block 35 is to ensure that the test sample 2 will not fall off or shift during the dragging process. Pins 38 are provided on both sides of the card block 35, one group of which is connected to the charging gun for providing power or signal transmission, and the other group of pins 38 is adapted to the wiring group.
[0040] The wiring group is a key component for connecting the other end of the test sample 2. It includes one or more circular plates 33, on which are arranged wiring ports 34 for connecting with the corresponding interfaces of the test sample 2. Through this connection mode, power or signals can be smoothly transmitted to the test sample 2 while maintaining the stability and reliability of the connection.
[0041] Moreover, the connection method is convenient enough and can meet the needs of use compared to the cable tie fixing method.
[0042] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 A protrusion 310 is provided at the bottom of the installation area 32 of the docking block 31 , and a slot 36 is provided at the top of the block 35 at the protrusion 310 . The slot 36 is adapted to the protrusion 310 to maintain the stability of the block 35 .
[0043] A flange 37 is provided on the top of the docking block 31 , and the flange 37 is adapted to the driving assembly 4 through fasteners.
[0044] A protrusion 310 is provided at the bottom of the installation area 32 of the docking block 31. This design is to ensure that the docking block 31 is firmly positioned in the test box 1. The presence of the protrusion 310 enables the block 35 to be accurately positioned in the installation area 32, thereby maintaining the fixity and stability of the test sample 2. At the top of the block 35, there is a structure with a slot 36. The slot 36 is adapted to the protrusion 310, so that the block 35 can be tightly embedded therein, further enhancing its stability. This design ensures that the connection between the docking block 31 and the test sample 2 is firm and reliable when performing a drag test.
[0045] Secondly, a flange 37 is provided on the top of the docking block 31, and the flange 37 is adapted to the drive assembly 4 through fasteners. The flange 37 is an important component connecting the docking block 31 and the drive assembly 4. It is fixed by fasteners to ensure a stable connection between the docking block 31 and the drive assembly 4. This design enables the drive assembly 4 to accurately control the movement of the docking block 31, thereby realizing the dragging operation of the test sample 2. At the same time, the presence of the flange 37 also improves the structural stability and durability of the entire system, ensuring the accuracy and reliability of the test process.
[0046] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 Slide bars are provided on both sides of the block 35 , which are adapted to the installation area 32 at the bottom of the docking block 31 . Sealing grooves 39 are provided at the pins 38 on both sides of the block 35 , which are adapted to the rubber ring 311 provided on the outer side of the circular plate 33 .
[0047] Slide bars are provided on both sides of the block 35, and these slide bars are adapted to the mounting area 32 at the bottom of the docking block 31. The design of the slide bars enables the block 35 to slide smoothly in the mounting area 32 of the docking block 31, thereby ensuring the stability and reliability of the block 35 during the dragging experiment. This design enables the block 35 to move along a preset stroke under the action of the driving assembly 4, thereby realizing the dragging operation of the test sample 2.
[0048] Secondly, sealing grooves 39 are provided at the pins 38 on both sides of the block 35. The function of the sealing grooves 39 is to ensure that the connection between the pins 38 and the block 35 is sealed reliably to prevent foreign matter from entering and causing unstable or damaged connections. Such a design enhances the reliability and durability of the connection, while protecting the safety of the internal circuit and wiring.
[0049] Finally, the sealing groove 39 is adapted to the rubber ring 311 provided on the outer side of the circular plate 33. The presence of the rubber ring 311 increases the sealing of the connection, and at the same time improves the stability and shock resistance of the connection. This design effectively prevents the influence of vibration and impact that may occur in the dragging test on the connection, and ensures the accuracy and reliability of the test process.
[0050] See also Figure 1 as well as Figure 8 The driving assembly 4 includes a slider 41 , the bottom of which is adapted to the fastener through a flange 37 , and two sets of guide rails 42 and tracks 43 for limiting the path are installed on the outer side of the slider 41 , and the tracks 43 are located above the guide rails 42 .
[0051] A driving motor is provided at the crawler belt 43 , and the driving motor drives the crawler belt 43 to drive the slider 41 to reciprocate linearly along the guide rail 42 .
[0052] The bottom of the slider 41 is matched with the fastener through the flange 37. Such a design ensures a stable connection between the slider 41 and the test box 1. Two sets of guide rails 42 and tracks 43 are installed on the outside of the slider 41. These guide rails 42 and tracks 43 are set to limit the moving path of the slider 41 and ensure that it performs linear reciprocating motion along the predetermined track. The guide rails 42 are located on the outside of the slider 41, and the tracks 43 are located above the guide rails 42. Such a layout enables the slider 41 to move stably under the guidance of the guide rails 42. At the same time, the setting of the tracks 43 increases the stability and smoothness of the movement of the slider 41.
[0053] Secondly, a driving motor is provided at the crawler 43 in the driving assembly 4. The driving motor is the power source for driving the slider 41 to perform linear reciprocating motion. By controlling the rotation of the crawler 43, the driving motor can drive the slider 41 to perform smooth linear movement along the guide rail 42. This design ensures that the force applied to the test sample 2 in the dragging experiment can be continuously and stably transmitted, thereby ensuring the accuracy and reliability of the experiment.
