DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basics of the utility model in a schematic manner, so it only shows the structure related to the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Please refer to Figure 1-6 A wire harness heat shrink device 100 for protecting a heat protector comprises a mounting plate 10, a baffle 20 rotatably connected to the mounting plate 10, a heating mechanism 30 for heating a heat shrink sleeve 203 on the wire harness 200, and a guide plate 40. The heating mechanism 30 is disposed on one side of the mounting plate 10, and the guide plate 40 is used to position the mounting plate 10.

[0026] The wiring harness 200 involved in this embodiment includes a wire 201 and a thermal fuse 202 arranged at one end of the wire 201 , and a heat shrink sleeve 203 arranged at the connection between the wire 201 and the thermal fuse 202 .

[0027] The mounting plate 10 is provided with a first mounting groove 11, a second mounting groove 12 and a third mounting groove 13 in sequence, a positioning block 14 is provided at one end in the length direction of the mounting plate 10, and an ear plate 15 is fixed to both ends in the length direction of the mounting plate 10 by screws. The first mounting groove 11, the second mounting groove 12 and the third mounting groove 13 are arranged in sequence along the width direction of the mounting plate 10, and the first mounting groove 11 is closer to the frame 31 than the third mounting groove 13. The width of the first mounting groove 11 is greater than the length of the thermal fuse 202 on the wiring harness 200, and the width of the second mounting groove 12 is greater than the length of the heat shrink sleeve 203 on the wiring harness 200.

[0028] An installation partition 16 is provided between the first installation slot 11 and the second installation slot 12, and an installation partition 2 17 is provided between the second installation slot 12 and the third installation slot 13. The installation partition 1 16 is provided with a plurality of clamping slots 1 161 adapted to the thermal protector, and the installation partition 2 17 is provided with a clamping slot 2 171 adapted to the clamping slot 1 161. When heating, the wire harness 200 is sequentially placed in the clamping slot 1 161 and the clamping slot 2 171. In this embodiment, the clamping slot 1 161 and the clamping slot 2 171 are provided in plurality and correspond to each other, so as to place a plurality of wire harnesses 200 at the same time for heating.

[0029] The groove wall of the first clamping groove 161 and the groove wall of the second clamping groove 171 are both provided with a limiting protrusion 1611. When the thermal protector is placed in the first clamping groove 161 and the second clamping groove 171, the limiting protrusion 1611 and the top of the wire harness 200 are abutted. Since the coating layer of the wire harness 200 has a certain elasticity, when placing the wire harness 200, the wire harness 200 can be inserted into the first clamping groove 161 and the second clamping groove 171.

[0030] The guide plate 40 is provided with a threaded hole 41 and a positioning groove 42 adapted to the positioning block 14. When the wiring harness 200 is heated, the positioning block 14 is clamped in the positioning groove 42 to facilitate positioning of the mounting plate 10 during heating, thereby increasing the accuracy of the heating position of the heating mechanism 30, thereby reducing the influence of the hot air blower 32 on the thermal fuse 202 of the wiring harness 200.

[0031] The baffle 20 can rotate to abut against the mounting partition 16, and the baffle 20 can rotate to cover the first mounting groove 11. Specifically, in this embodiment, the baffle 20 is provided with a rotating shaft 21, and the rotating shaft 21 is rotatably connected to the ear plates 15 on both sides of the mounting plate 10 in the length direction.

[0032] The heating mechanism 30 includes a frame 31 disposed on one side of the mounting plate 10 and a hot air blower 32 disposed on the frame 31 . The hot air blower 32 is disposed toward the second mounting groove 12 .

[0033] The frame 31 is provided with an adjustment slot 311, which is arranged along the length direction of the mounting plate 10. The adjustment slot 311 is provided with a threaded hole 2 that matches the threaded hole 1 41, and the threaded hole 2 is not shown in the figure. The guide plate 40 is provided with a fixing screw 43 that is threadedly connected to the threaded hole 1 41 and the threaded hole 2. The guide plate 40 is slidably arranged in the adjustment slot 311 and fixed by the fixing screw 43.

[0034] The heating mechanism 30 further includes a driving assembly 33 and a sliding block 34 disposed on the frame 31, and a temperature controller 35 disposed on the frame 31. The sliding block 34 is provided with a sliding groove 341. The driving assembly 33 includes a moving block 331 connected to the hot air blower 32, a rotating screw 332 rotatably disposed in the sliding groove 341, and a rotating motor 333 driving the rotating screw 332 to rotate. The moving block 331 is slidably disposed in the sliding groove 341, the rotating screw 332 passes through the moving block 331 and is threadedly connected to the moving block 331, and the output shaft of the rotating motor 333 is coaxially fixed with the rotating screw 332. The temperature controller 35 is electrically connected to the hot air blower 32, and the temperature controller 35 is used to control the heating temperature of the hot air blower 32. The temperature controller 35 is a prior art, and the accompanying drawings corresponding to this embodiment do not show the specific structure of the temperature controller 35.

[0035] When the hot air blower 32 is moved, the rotating motor 333 can be started to rotate the rotating screw 332, so that the moving block 331 drives the hot air blower 32 to move along the length direction of the second installation groove 12, thereby heating the heat shrink sleeve 203 located in the second installation groove 12.

[0036] Beneficial effect: When heating, the wire harness 200 is sequentially placed in the first installation groove 11 and the second installation groove 12, and the thermal fuse 202 of the wire harness 200 is completely located in the first installation groove 11, and the heat shrink sleeve 203 of the wire harness 200 is completely located in the second installation groove 12, and then the baffle 20 is rotated to block the thermal fuse 202 of the wire harness 200, and then the hot air blower 32 is started to heat the heat shrink sleeve 203 located in the second installation groove 12. In this way, the influence of the hot air blower 32 on the thermal fuse 203 during heating can be reduced, thereby improving the quality of the wire harness 200.
