In new energy vehicles, the welding points of the wiring harness are key nodes for power transmission. The welding quality directly affects the safety and service life of the system. Tensile testing can verify the firmness of the welding points to ensure that they can withstand the expected mechanical stress and will not break due to vibration, pulling and other factors.

The description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] See also Figures 1 to 4 The utility model relates to a portable new energy line tension detection device, including a support 1 and two tensile members. A stroke component is provided on the support 1, and the two tensile members are movably arranged on the support 1 in an opposing manner through the stroke component; one of the tensile members is used to connect one end of the line, and the other tensile member is used to connect the other end of the line. The two tensile members are driven by the stroke component to move along the tensile path on the support 1 and away from each other to perform tensile detection on the line.

[0027] There are two groups of stroke components, namely the first stroke component and the second stroke component. The first stroke component is arranged on the support 1, the second stroke component is arranged on the first stroke component, and the stretching member is arranged on the second stroke component; wherein, the first stroke component is used to drive the two stretching members to stretch the line once to straighten the line in a folded or bent state; the second stroke component is used to drive the two stretching members to stretch the line for a second time to complete the stretching test.

[0028] Specifically, the support 1 includes a top plate 101 and two vertical plates 102 arranged on the bottom surface of the top plate 101, and the two vertical plates 102 are parallel to each other; the top plate 101 and the two vertical plates 102 enclose a accommodating chamber, and the accommodating chamber forms openings at both ends of the length direction of the support 1; the first stroke component includes a guide groove 103 arranged on the top plate 101 of the support 1, and a bidirectional manual screw arranged in the accommodating chamber inside the support 1; the guide groove 103 is connected to the accommodating chamber inside the support 1 and is parallel to the length direction of the support 1; the bidirectional manual screw includes a bidirectional screw body 2 parallel to the length direction of the support 1, and the top plate 101 of the support 1 is at both ends in the length direction A support block 3 is provided, and an axial hole is provided on the two support blocks 3.

[0029] During one stretching, the bidirectional screw body 2 is driven to rotate forward by operating the hand wheel 4, and the two moving blocks 5 on the bidirectional screw body 2 slide along the guide groove 103 and move away from each other, correspondingly driving the two stretching parts to move away from each other to complete the line straightening; by manually driving the bidirectional manual screw, the stretching parts can gradually move away from each other, effectively avoiding the line from being quickly straightened from a folded or bent state, resulting in stress concentration at the end of the line and premature breakage, thereby ensuring the smooth progress of the stretching test and the detection accuracy.

[0030] A locking mechanism is provided on the support 1, which is used to limit the rotation of the bidirectional screw body 2 after the line is straightened; the locking mechanism includes a locking block 6 arranged in an internal accommodating chamber of the support 1, and a locking rod cavity is provided on the locking block 6, and the bidirectional screw body 2 of the bidirectional manual screw can be rotatably inserted through the locking block 6; the top of the locking block 6 extends out of the top surface of the top plate 101 of the support 1 through the guide groove 103 and is provided with a fixing plate 7, which is fixedly installed on the top plate 101 of the support 1 by bolts, and a threaded through hole connected to the locking rod cavity is provided on the fixing plate 7, and the inner thread of the threaded through hole is matched with a first locking bolt 8, and the first locking bolt 8 is used to enter the locking rod cavity after the line is straightened and abut against the bidirectional screw body 2 to complete the locking.

The guide block is parallel to the length direction of the support 1 and slides with the guide block through the matching groove so that the moving seat 9 can slide relative to the moving block 5; a threaded through hole is provided at the bottom of the vertical plate, and the threaded through hole on the vertical plate is threadedly matched with the one-way screw body 13.

[0034] During clamping, one end of the line is clamped and fixed with the clamping claw 16 of the detector, and the other end of the line passes through the internal clamping cavity of the jacket 17 from the line inlet 17a of the jacket 17, and passes through the outside from the line outlet 17b of the jacket 17, and cooperates with the bolt hole on the locking plate 17d through the third locking bolt 20 to make the two locking plates 17d close to each other, and correspondingly drive the line inlet 17a of the jacket 17 to contract and clamp the line; when the line inlet 17a of the jacket 17 contracts, the two opposite groove side walls of the U-shaped avoidance groove 17c approach each other, and the inner side wall of the line inlet 17a of the jacket 17 forms a surface contact with the outer side wall of the line, so that the line is evenly stressed at the clamping point; in this embodiment, the jacket 17 is made of elastic material, such as copper, so that after the tensile test is completed and the bolts are loosened, the line inlet 17a of the jacket 17 can be restored to open.
