The embodiment relates to a wire harness protection structure, which comprises a protection main body 1, wherein the protection main body 1 can be fixed in a mounting hole of a workpiece 2 and used for shielding the inner wall of the mounting hole. A through hole 101 is formed in the protective body 1, a restraining portion 102 is arranged on the inner wall of the through hole 101, and the restraining portion 102 is used for limiting the radial movement of the wire harness 3.

The arrangement of the via hole 101 on the protection main body 1 can facilitate the passing of the wiring harness 3, and meanwhile, the wiring harness 3 can be conveniently fixed by arranging the restriction part 102 on the inner wall of the via hole 101, so that mutual friction between the wiring harness 3 and the protection main body 1 is prevented, and the outer skin of the wiring harness 3 is protected from being worn.

Based on the above design concept, an exemplary structure of the wire harness protection structure of the embodiment is as shown in fig. 1, the protection main body 1 is detachably fixed on the workpiece 2, and the protection main body 1 is more convenient to replace when damaged, so that the use convenience is improved.

As shown in fig. 2, a limiting portion 104 and a clamping portion 105 are formed on the protection body 1, and when the protection body 1 is inserted into the mounting hole, the limiting portion 104 and the clamping portion 105 are respectively blocked at two sides of the product 2, so as to fix the protection body 1 on the product 2.

In the present embodiment, the protection body 1 includes a protection plate 106, and the protection plate 106 is U-shaped so that it can be attached to the inner wall of the installation hole. The limiting portion 104 includes a flange formed on the front side of the protection plate 106, the flange extends to the outside of the protection plate 106, and the flange follows the shape of the workpiece 2, so that the flange is attached to the workpiece 2. The turn-ups arrange that on the one hand can fix the guard plate 106 on the mounting hole with the cooperation of joint portion 105, on the other hand can increase the structural strength of protection main part 1.

The three clamping portions 105 are formed on the protection plate 106 and comprise one arranged on the horizontal part of the U-shaped protection plate 106 and one arranged on each of the two vertical parts of the protection plate 106, and the clamping portions 105 are arranged at intervals along the protection plate 106 along the bending direction of the inner wall, so that the protection plate 106 can be more firmly fixed on the product 2. Particularly, joint portion 105 is the wedge and arranges, and joint portion 105 sets up from thick to thin from being close to the one end of turn-ups to keeping away from the one end of turn-ups, can be convenient for protect the main part 1 in the inserting of mounting hole. Of course, the number of the snap-in portions 105 is not limited to three, and may be other suitable numbers such as four, five, six, and the like.

As shown in fig. 3, a wire harness restricting hole 1026 is formed in the restricting portion 102, a slit 1023 is formed on a side wall of the wire harness restricting hole 1026, and the wire harness 3 can enter the wire harness restricting hole 1026 through the slit 1023 under the action of external force, so as to limit and fix the wire harness 3. And a cutout 1023 is formed in a side wall of the wire harness restraint hole 1026 to facilitate passage of the wire harness through the cutout 1023 into the wire harness restraint hole 1026.

Specifically, the restraint portion 102 includes two grip arms 1021 arranged at a left-right pitch, and an elastic arm 1022 molded on each grip arm 1021. So set up, can be convenient for enclose synthetic pencil restraint hole 1026 to carry out spacing fixed to the pencil.

Meanwhile, as the elastic arms 1022 have elasticity, certain deformation can occur, the gap 1023 is temporarily enlarged to allow the wire harness to enter, and then the elastic arms 1022 reset, the gap 1023 becomes small, so that the wire harness can not leave the wire harness restriction hole 1026 from the gap 1023 under the condition without external force. The cross section of the elastic arm 1022 is in an arc shape with the middle part bending towards the interior of the wire harness restriction hole 1026, so that the elastic arm 1022 can deform to change the size of the gap 1023 on one hand, and on the other hand, when the wire harness is accommodated in the wire harness restriction hole 1026, the wire harness can be prevented from shaking up and down.

In addition, first rounded corners 103 are formed at front and rear sides of the shielding plate 106, second rounded corners 1024 are formed at front and rear sides of the grip arm 1021 and the elastic arm 1022, and third rounded corners 1025 are formed at the other side of the elastic arm 1022 to the side where the grip arm 1021 is connected. When the pencil is retrained in pencil restraint hole 1026, first fillet 103, second fillet 1024 and third fillet 1025's setting, the friction of reducible edge department of protecting main part 1 to the pencil prevents that the protection crust of pencil from being damaged.

Finally, the wire harness protection structure is integrally formed by adopting an injection molding process, so that the processing and forming of the wire harness protection structure can be facilitated, and the wire harness protection structure is made of a nylon material (such as PA66), so that the weight can be reduced while the structural strength is ensured.

The utility model discloses a pencil protective structure through set up via hole 101 in protection main part 1, can be convenient for the passing through of pencil, simultaneously through set up the pars constraining 102 on the inner wall at via hole 101, can be convenient for fix the pencil, prevent that the pencil from along the radial movement of self, has prevented to advance to take place the looks mutual friction between pencil and the protection main part 1, and the crust of protection pencil is not worn and torn, and then prevents that the circuit from taking place the short circuit.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
