[0027] Embodiment

[0028] As Figures 1-3 shown, a harness test fixture for an automotive temperature sensor proposed by the present utility model includes a bobbin 1. The bobbin 1 is a hollow cylinder with openings at both ends. It further includes a through hole 2 opened on the bobbin 1. A clamping plate 6 for clamping the harness is provided in the through hole 2. The clamping plate 6 is slidably installed in the through hole 2. A rubber pad 13 is fixedly installed at the bottom of the through hole 2. The rubber pad 13 is used to increase the friction between the harness and the through hole 2, thereby improving the clamping force. Moreover, the rubber pad 13 can also protect the integrity of the surface of the harness.

[0029] Wherein, fixing rods 11 are fixedly installed on both sides of the through hole 2. The clamping plate 6 is slidably sleeved on the two groups of fixing rods 11. Two groups of springs 12 are fixedly connected between the top of the through hole 2 and the top of the clamping plate 6. The springs 12 are respectively sleeved outside the fixing rods 11. A pull plate 9 is fixedly installed at the top of the clamping plate 6. By pulling the pull plate 9, the clamping plate 6 slides upward on the fixing rods 11, facilitating the harness to pass through the through hole 2. When the pull plate 9 is released, the clamping plate 6 presses on the harness under the action of the springs 12 to clamp the harness.

[0030] In addition, the length of the clamping plate 6 is 1 - 2 cm less than the length of the through hole 2. A plurality of semi-circular grooves 10 are opened at the bottom of the clamping plate 6. The radii of the semi-circular grooves 10 are 0.30 mm, 0.50 mm, 0.80 mm, 1.00 mm, 1.25 mm, and 2.00 mm respectively. When the pull plate 9 is released, the position of the harness can be adjusted according to the diameter of the harness, so that the harness is clamped in the appropriate semi-circular groove 10 and rubber pad 13, realizing the clamping of harnesses with different diameters, expanding the application range, and being conducive to popularization and use.

[0031] In this embodiment, the auxiliary structure includes a fixing plate 4 and a rotating plate 14, and arc-shaped holes 5 through which the wire harness can pass are formed in both the fixing plate 4 and the rotating plate 14. The fixing plate 4 is fixedly installed on the top of the wire reel 1, and the rotating plate 14 is rotatably installed on the bottom of the wire reel 1. The auxiliary component further includes a rotating column 8 fixedly installed on the top of the rotating plate 14. A circular hole through which the rotating column 8 can pass is formed in the fixing plate 4. Rotate the rotating block 3 to drive the rotating column 8 to rotate, so that the rotating plate 14 rotatably installed at the bottom of the wire reel 1 rotates, and the excess wire harness in the wire reel 1 is wound around the rotating column 8 during the rotation of the rotating plate 14, realizing that the wire harness is not easily slipped from the wire reel 1.

[0032] Among them, there are two groups of arc-shaped holes 5, and the two groups of arc-shaped holes 5 are symmetrically arranged. A rotating block 3 is fixedly installed at one end of the rotating column 8 passing through the fixing plate 4, and multiple anti-slip strips 7 are fixedly installed on the outside of the rotating block 3. The anti-slip strips 7 are used to increase the friction of the rotating block 3, facilitating the use by the staff.

[0033] Working principle: During the working process of the present utility model, first pass the wire harness through the arc-shaped hole 5 on the rotating plate 14, then pull the pull plate 9, and the clamping plate 6 slides on the fixed rod 11, so that one end of the wire harness is pulled out from the through hole 2. Release the pull plate 9, and the clamping plate 6 presses on the wire harness under the action of the spring 12 to clamp the wire harness. Secondly, rotate the rotating block 3 to drive the rotating column 8 fixedly connected to the rotating block 3 to rotate, so that the rotating plate 14 rotatably installed at the bottom of the wire reel 1 rotates, and the excess wire harness in the wire reel 1 is wound around the rotating column 8 during the rotation of the rotating plate 14. Thus, the wire harness is clamped and has the advantage of not being easily dropped. The structure is simple, the operation is convenient, and the work efficiency is improved. At the same time, when the pull plate 9 is released, the position of the wire harness can be adjusted according to the diameter of the wire harness, so that the wire harness is clamped in the suitable semi-circular groove 10 and the rubber pad 13, realizing the clamping of wire harnesses with different diameters, expanding the application range, and being conducive to popularization and use.

[0034] The above specific embodiments are only several alternative embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
