[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] like Figure 1-4 As shown, the utility model provides a turntable type multi-model tension testing device for automobile wiring harnesses, comprising: a first tension head 1 and a second connecting head 3, a harness clamp 2 is installed at the end of the first tension head 1, a mounting plate 4 is provided at the end of the second connecting head 3, a turntable 5 is connected to the front side of the mounting plate 4 through a rotating shaft 58, the turntable 5 comprises a turntable body 51, a side wall is provided at the edge of the turntable body 51, a plurality of slots 55 of different widths are provided around the circumference of the side wall, a plurality of positioning holes 52 corresponding to the slots 55 are provided around the rotating shaft 58 on the turntable body 51, a plugging hole 41 is provided at a position corresponding to the positioning hole 52 on the mounting plate 4, and a plug post 53 which passes through any one of the positioning holes 52 and is plugged into the plugging hole 41 is movably provided on the turntable 5.

[0017] Specifically, when in use, one end of the wire harness is fixed by the wire harness clamp 2, the turntable body 51 is rotated to a position where the slot 55 corresponding to the diameter of the wire harness is aligned with the wire harness clamp 2, the terminal at the other end of the wire harness is clamped on the slot 55, and then the tension test can be achieved by pulling the first tension head 1.

[0018] The corresponding diameter data is marked on one side of the positioning hole 52 on the end surface of the turntable body 51 , and the plug post 53 inserted between the positioning hole 52 and the plug hole 41 can keep the turntable body 51 at the corresponding tensile test position.

[0019] In order to facilitate the use of the plug post 53 and prevent it from being lost, the plug post 53 is connected to the second connector 3 via a connecting rope.

[0020] In order to realize the positioning of the connecting ring at the end of the wiring harness, a threaded hole is provided on the turntable body 51, and a screw 57 is connected to the threaded hole. The screw 57 is connected to one end of the handle 54, and the screw 57 passes through the pressure plate 56. A spring 6 is provided between the pressure plate 56 and the turntable body 51, and the pressure plate 56 can cooperate with the connecting ring for positioning, so that the connecting ring can be fixed on the turntable body 51 to maintain the tension test state. When the handle 54 drives the screw 57 to rotate, the pressure plate 56 can be pressed down and tightened. When the handle 54 rotates, the spring 6 can automatically push the pressure plate 56 up, and the connecting ring can be separated from the pressure plate 56. In addition, one end of the pressure plate 56 is inserted into the side wall on the edge of the turntable body 51, so that the pressure plate 56 can be prevented from rotating.

[0021] In order to facilitate the clamping of the wire harness, the wire harness clamp 2 includes two side-by-side clamping plates, and an adjusting screw is disposed transversely through the clamping plates.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
