Description

Technical Field

[0003] The existing negative ion generator usually includes an emission end that generates high-voltage corona and a main control module. The emission end is connected to the main control module through a wire harness. When installing the negative ion emitter, the wire harness will be subjected to a certain pulling force between the emission end and the main control module. If the wire harness is not fixed properly, the wire harness is likely to move when being pulled, which will cause the emission end to be pulled and move accordingly, thus easily causing damage to the emission end.

[0004] Therefore, there is an urgent need for a wire harness fixing device to solve the above problems. Summary of the Utility Model

[0036] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0037] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements.

The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0039] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] When installing the negative ion emitter, the wire harness will be subjected to a certain pulling force between the emitting end and the main control module. If the wire harness is not fixed properly, the wire harness is likely to move when being pulled, which will cause the emitting end to be pulled and move accordingly, thus easily resulting in the damage of the emitting end. For this reason, a wire harness fixing device is proposed in this embodiment, which can fix the wire harness from two different directions to ensure the stability of the wire harness when it is fixed.

[0041] Specifically, please refer to Figure 1 and Figure 2, the wire harness fixing device includes a housing 1, a first positioning structure 2 and a second positioning structure 3. The housing 1 has an inlet 11 for the wire harness 100 to penetrate into and an outlet 12 for the wire harness 100 to penetrate out. The first positioning structure 2 is arranged inside the housing 1. A clamping groove 21 is formed between the first positioning structure 2 and the inner side wall of the housing 1. The clamping groove 21 can clamp the wire harness 100 in the first direction at the first position. The second positioning structure 3 is arranged inside the housing 1. The second positioning structure 3 can extrude the wire harness 100 in the second direction at the second position. Wherein, the first position and the second position are sequentially arranged between the inlet 11 and the outlet 12. The first direction and the second direction are perpendicular to each other and are respectively perpendicular to the extending direction of the wire harness 100.

[0042] In this embodiment, the wire harness 100 penetrates into the interior of the housing 1 from the inlet 11 of the housing 1 and penetrates out of the housing 1 from the outlet 12. When the wire harness 100 located inside the housing passes through the clamping groove 21 at the first position and the second positioning structure 3 at the second position in sequence, the clamping groove 21 can apply a clamping force in the first direction to the wire harness 100, and the second positioning structure 3 can apply an extrusion force to the wire harness 100, so as to avoid the movement of the wire harness 100 when being pulled and improve the stability of the wire harness 100.

[0043] Please refer to Figure 2 With Figure 3 , the first positioning structure 2 includes a clamping portion 22. A clamping groove 21 is formed between the clamping portion 22 and the inner side wall of the housing 1. It can be understood that the inner side wall of the housing 1 is a structure originally possessed by the housing 1 itself. In this embodiment, it is used as a part of the clamping groove 21, which can reduce the processing of the clamping structure, improve the production efficiency of the wire harness fixing device, and also reduce the production cost.

[0044] In addition, it should be noted that the diameters of the wire harnesses 100 used under different working conditions will be different. Therefore, during the production process, the interval between the clamping portion 22 and the inner side wall of the housing 1 is determined according to the diameter of the wire harness 100.

[0045] Further, the first positioning structure 2 further includes a bent portion 23 connected to the clamping portion 22. The wire harness 100 passing through the bent portion 23 closely adheres to the bent portion 23 to form a bend with respect to the wire harness 100 clamped in the clamping portion 22. Since the wire harness 100 has a certain elasticity and has elastic potential energy to return to its initial position after being bent, when the wire harness 100 is bent, it applies a resisting force to the bent portion 23. Relatively speaking, the bent portion 23 applies a reaction force to the wire harness 100. When the direction of this reaction force is the same as the direction of the pulling force received by the wire harness 100, at this time, the wire harness 100 is separated from or about to be separated from the bent portion 23, then this reaction force decreases or even disappears, and the wire harness 100 is fixed under the action of its own elastic potential energy and the clamping force of the clamping groove 21. When the direction of this reaction force is different from the direction of the pulling force received by the wire harness 100, the reaction force can offset part or even all of the pulling force received by the wire harness 100, so as to further ensure the stability of the wire harness 100 and further prevent the wire harness 100 from being pulled and moved.

[0046] Specifically, please refer to Figure 4 , the bent portion 23 includes a first bent portion 231 and a second bent portion 232. The first bent portion 231 and the second bent portion 232 are respectively connected to both ends of the clamping portion 22 and jointly form a C-shaped structure, and the opening of this C-shaped structure faces away from the inner side wall of the housing 1. The wire harness 100 passing through the first bent portion 231 and the second bent portion 232 respectively closely adheres to the first bent portion 231 and the second bent portion 232 to form a bend with respect to the wire harness 100 clamped in the clamping portion 22. When the wire harness 100 is bent, both the first bent portion 231 and the second bent portion 232 can apply reaction forces to the wire harness 100, and the directions of the two reaction forces are different, so as to cope with the pulling forces received by the wire harness 100 under different working conditions.

[0047] Please refer to Figure 5 and Figure 6 , in this embodiment, the housing 1 includes a first cover body 13 and a second cover body 14 which are snap-fitted. The first positioning structure 2 is arranged on the first cover body 13, and the second positioning structure 3 is arranged between the first cover body 13 and the second cover body 14. Among them, the first cover body 13 and the second cover body 14 are connected by a snap-fitting component. The first positioning structure 2 can form a clamping groove 21 with the inner side wall of the first cover body 13. After the first cover body 13 and the second cover body 14 are snap-fitted, the second positioning structure 3 can squeeze the wire harness 100 along the second direction, so as to fix the wire harness 100.

[0048] Exemplarily, a plurality of fastening components are provided, and the plurality of fastening components are evenly distributed on the outer side wall of the housing 1 to ensure the connection strength between the first cover 13 and the second cover 14. Any one of the fastening components includes a male buckle and a female buckle, the male buckle and the female buckle are adapted to each other, the male buckle is provided on the first cover 13, the female buckle is provided on the second cover 14, and is correspondingly arranged with the male buckle.

[0049] In addition, the wire inlet 11 and the wire outlet 12 are respectively arranged on two opposite side walls of the first cover 13, so as to facilitate the operator to perform preliminary positioning on the wire harness 100, thereby facilitating the fixing of the wire harness 100 in the clamping groove 21 and the second positioning structure.

[0050] Please refer to Figure 5 , in this embodiment, the second positioning structure 3 includes a wire pressing portion 31, the wire pressing portion 31 is arranged on the second cover 14, and after the second cover 14 is buckled on the first cover 13, the wire pressing portion 31 can press the wire harness 100 towards the first cover 13 in the second direction. It can be understood that when the second cover 14 is buckled, it can drive the wire pressing portion 31 to approach the wire harness 100. After contacting the wire harness 100, it can push the wire harness 100 to move towards the first cover 13. When the wire harness 100 is blocked and cannot move, the second cover 14 can apply a squeezing force to the wire harness 100 to fix the wire harness 100.

[0051] Furthermore, a clamping structure is arranged on the side of the wire pressing portion 31 facing the wire harness 100 to prevent the wire harness 100 from detaching from the wire pressing portion 31 when the wire harness 100 is being squeezed, thereby further improving the stability of the wire harness 100.

[0052] Exemplarily, the clamping structure is serrated, and the serrated setting can increase the contact area between the wire pressing portion 31 and the wire harness 100, thereby further improving the stability of the wire harness 100.

[0053] In addition, in this embodiment, the second positioning structure 3 further includes a wire clamping plate 32, the wire clamping plate 32 is arranged on the first cover 13 and has a wire clamping groove 321 through which the wire harness 100 passes, and the wire pressing portion 31 is correspondingly arranged with the wire clamping groove 321. When the operator threads the wire harness 100, the wire harness 100 is passed out from the wire clamping groove 321 to perform preliminary positioning on the wire harness 100 to avoid the wire harness 100 from shifting during the buckling process of the first cover 13 and the second cover 14. During the buckling process, the second cover 14 can squeeze the wire harness in the wire clamping groove 321 in the second direction, thereby fixing the wire harness at the second position.

[0054] Based on the above, in this embodiment, a negative ion generator is further proposed, which includes a transmitting end, a main control module and the above-mentioned wire harness fixing device. The transmitting end and the main control module are connected by a wire harness 100. One end of the wire harness 100 is connected to the main control module, and the other end passes through the wire harness fixing device and then is connected to the transmitting end. Under the action of the wire harness fixing device, the wire harness 100 is fixed, so as to prevent the transmitting end from being pulled along when the wire harness 100 is pulled and moved, and further prevent the transmitting end from being damaged.

[0055] Among them, the wire harness 100 of the negative ion generator includes a high-voltage wire harness and a ground wire harness. When the wire harness 100 is fixed by the wire harness fixing device, two wire inlet ports 11 and two wire outlet ports 12 are opened on the housing 1 to facilitate the penetration of the high-voltage wire harness and the ground wire harness respectively; correspondingly, there are two first positioning structures 2, and two clamping grooves 21 are formed between the two first positioning structures 2 and the two opposite inner side walls of the housing 1 respectively, and the two clamping grooves 21 can clamp the high-voltage wire harness and the ground wire harness respectively.

[0056] In addition, since the diameters of the high-voltage wire harness and the ground wire harness are different, the width of one of the clamping grooves 21 needs to be greater than the width of the other clamping groove 21, so as to fix the high-voltage wire harness and the ground wire harness respectively. During the production process, the width of the clamping groove 21 is determined according to the diameter of the wire harness to be clamped, and no specific limitation is made here.

[0057] Furthermore, a blocking member 4 is connected between the two first positioning structures 2. The blocking member 4 can block the area between the two first positioning structures 2 to prevent the operator from accidentally passing the high-voltage wire harness and the ground wire harness through between the two first positioning structures 2, so that the high-voltage wire harness and the ground wire harness cannot be clamped by the clamping grooves 21. Among them, the blocking member 4 is preferably a baffle, and both ends of the baffle are connected to the two first positioning structures 2 respectively.

[0058] In addition, the second positioning structure 3 can simultaneously squeeze the high-voltage wire harness and the ground wire harness. Specifically, two wire clamping grooves 321 are provided on the wire clamping plate 32, and the width of one of the wire clamping grooves 321 is greater than the width of the other wire clamping groove 321 to adapt to the high-voltage wire harness and the ground wire harness.

[0059] Correspondingly, there are two wire pressing parts 31, which are respectively arranged corresponding to the two wire clamping grooves 321. In some other feasible embodiments, the two wire pressing parts 31 are of an integral structure.

[0060] During the assembly process of the negative ion generator, the assembly steps of the high-voltage wire harness and the ground wire harness are the same. Here, the assembly method of the high-voltage wire harness is described: One end of the high-voltage wire harness is sequentially passed through the wire inlet port 11, the clamping groove 21, the wire clamping groove 321 and the wire outlet port 12, and then the second cover body 14 and the first cover body 13 are buckled together, so as to complete the assembly of the high-voltage wire harness.

[0061] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
