Description

Technical Field

[0001] This utility model relates to the technical field of wire harness fixing devices, specifically, to an insulated wire code for fixing wire harnesses of different outer diameters in vehicles. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] With the rapid development of the new energy vehicle industry, high-voltage wiring harnesses, as key components connecting high-voltage parts in new energy vehicles, have gradually attracted widespread attention in their design and application. The main function of high-voltage wiring harnesses is to transmit high-voltage electrical energy. Different high-voltage components require different power, and consequently, different current requirements. Therefore, the wire diameter of the high-voltage wiring harness needs to be selected according to the actual application, and the outer diameter of the outermost corrugated tube corresponding to different wire diameters also varies. During the production and design process, the wire diameter of the wiring harness may change due to various factors. At the same time, as the number of companies producing high-voltage wiring harnesses continues to increase, there are certain differences in production standards between manufacturers. Even wiring harnesses with the same wire diameter may have slight differences in outer diameter dimensions produced by different manufacturers. These factors pose challenges to the selection of insulating wire clips (i.e., wire clamps that secure the wiring harness during vehicle assembly) for fixing the high-voltage wiring harness. Because the fixing wire clips need to adapt to changes in the outer diameter of the wiring harness, this process increases the complexity of design selection, further affecting production efficiency and cost control.

[0004] The inventors discovered in their research that current single-wire fixed wire code designs on the market are typically only suitable for wire harnesses of a specific outer diameter. This type of fixed wire code lacks versatility for high-voltage wire harnesses of different diameters. During the design process, technicians need to match the fixed wire code one by one for different wire diameters, increasing the complexity of selection. Because existing fixed wire codes have a limited range of adaptability to wire diameters, deviations are prone to occur during selection or installation, thus affecting the overall vehicle assembly quality. Construction is inconvenient; workshop workers need to constantly adjust the fixed wire code according to wire harnesses of different diameters, increasing the difficulty of construction. The difficulty in selection and the inconvenience of construction indirectly prolong the production cycle and increase the company's manufacturing costs. Utility Model Content

[0005] To solve the above problems, this utility model proposes an insulated wire code for fixing wire harnesses of different outer diameters in vehicles. By setting a spring piece on the inner wall of the wire code, the insulated wire code can be used to fix wire harnesses of different outer diameters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] One or more embodiments provide an insulated wire code for fixing wire harnesses of different outer diameters in a vehicle, including a wire code body, a main body groove on the wire code body, a snap cover that can be opened and closed on the main body groove, the main body groove and the snap cover are connected to form a receiving space for accommodating the wire harness; spring pieces are provided on the inner walls of the main body groove and the snap cover.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This utility model's insulated wire clip incorporates a spring clip within the space accommodating the wire harness, allowing the clip to adapt to wire harnesses within a certain diameter range. This enables the fixing of wire harnesses of different diameters. The height of the spring clip can be adjusted to accommodate different wire harness diameters. The design includes a main body groove for fixing the wire harness and a locking cover. The locking cover, which can be opened and closed, allows the wire harness to be placed on the main body groove. Pressing the cover into the groove, combined with the elastic force of the spring clip, provides stable fixing of the wire harness, while also enabling quick installation and removal of the wire harness.

[0010] The advantages and additional benefits of this utility model will be described in detail in the following specific embodiments. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0018] It should be noted that the terminology used herein is for descriptive purposes only and is not intended to limit the exemplary embodiments according to this invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. It should be noted that, without conflict, the various embodiments and features within those embodiments can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0019] In one or more of the technical solutions disclosed in the embodiments, such as Figures 1 to 2 As shown, an insulated wire code for fixing wire harnesses of different outer diameters in a vehicle includes a wire code body, a main body groove 2 is provided on the wire code body, and a cover 4 is provided on the main body groove 2 that can be opened and closed. The main body groove 2 and the cover 4 are connected to form a receiving space for accommodating the wire harness; a spring piece 3 is provided on the inner wall of the main body groove 2 and the cover 4.

[0020] In this embodiment, a spring piece 3 is provided in the accommodating space of the wire harness, which enables the insulated wire code to adapt to wire harnesses within a certain wire diameter range, thereby realizing the fixing of wire harnesses of different wire diameters. The range of wire diameters that can be adapted can be adjusted by adjusting the height of the spring piece 3. A main body groove 2 for fixing the wire harness and a locking cover 4 are provided. The locking cover 4 is openable and closable on the main body groove 2. After the wire harness is placed on the main body groove 2, the locking cover 4 is pressed and locked into the main body groove 2. With the elastic force of the spring piece 3, the wire harness can be stably fixed, and the wire harness can also be quickly installed and removed.

[0021] This implementation significantly improves installation speed through the combination of quick-connect holes and elastic clips 3, avoiding the complex procedures required for traditional bolt connections. The simple design of the insertion holes and elastic clips facilitates manufacturing, reduces production costs, and enhances the connection stability between the insulated wire code and the bracket.

[0022] In this embodiment, the high-voltage wiring harness refers to the wiring harness that supplies power to the high-voltage devices of the vehicle, such as the air conditioner. Generally, corrugated pipes are installed to improve the safety of the wiring harness.

[0023] In some embodiments, one end of the main body groove 2 and the cover 4 are connected by soft plastic, and the other end is connected by a snap fastener.

[0024] In this embodiment, soft plastic is used for connection, which ensures the integrity of the insulated wire code and avoids the pairing part when installing separately. At the same time, the use of soft plastic for fixing the wire harness with a pressing method provides a buffered rebound force when pressing, avoiding excessive rigid compression of the wire harness and causing damage.

[0025] Furthermore, at one end of the soft plastic connection, a protrusion 2-1 is provided on the main body groove 2, and a receiving groove 4-1 is provided on the cover 4, with the protrusion 2-1 matching the receiving groove 4-1;

[0026] Optionally, the main groove 2 includes a vertically protruding main body 2-2, and the side arm 2-3 extending laterally from the end of the vertically protruding main body 2-2 forms an L-shaped structure;

[0027] Furthermore, the side arm 2-3 extending laterally from the end of the protrusion 2-1 has a certain tilt angle, so that the included angle between the vertical protrusion body 2-2 and the side arm 2-3 extending laterally from the end is less than 90°.

[0028] In the above solution, the connection point of the main groove 2 and the cover 4 through the soft plastic forms the first locking structure, which can not only prevent the wire code cover from moving up and down, but also ensure that the cover 4 and the main groove 2 of the wire code do not have relative displacement in the left and right direction, thus improving the stability of the wire harness fixing.

[0029] In some embodiments, the main body groove 2 and the other end of the cover 4 are connected by a snap-fit ​​connection, the snap-fit ​​connection structure being as follows: Figure 1 As shown, a slot 6 is provided on the end face of the main groove 2, and a retaining plate 5 is provided on the cover 4; the width of the slot 6 is adapted to the thickness of the retaining plate 5, a retaining hole 6-1 is provided on the outer side wall of the slot 6, and a buckle 5-1 is provided on the retaining plate 5, with the retaining hole 6-1 matching the buckle 5-1.

[0030] Specifically, the snap-fit ​​hole 6-1 is set as a quadrilateral through hole, and the buckle 5-1 is set as an inverted triangular cone with the top extending inward and forming a hook shape, which is used to insert and fix in the corresponding snap-fit ​​hole 6-1 to form a second locking structure.

[0031] In a further technical solution, the two sides of the card plate 5 are provided with first protruding ribs 5-2, and a limiting space is formed between the two first protruding ribs 5-2. The upper end of the outer wall of the card slot 6 is provided with a sheet-like structure, and the width of the sheet-like structure is equal to that of the limiting space, so that the sheet-like structure can be set in the limiting space.

[0032] In the above embodiment, the upper end of the outer wall of the slot 6 is a sheet-like structure. There is an outward protrusion on each side of the outer shell of the cover 4. After the cover 4 is closed and connected to the main body groove 2, it forms a structure that prevents the cover 4 from wobbling left and right. The first locking structure between the main body groove 2 and the cover 4 serves as an auxiliary fixing mechanism. After the second locking structure takes effect, it further ensures the reliability of the wire code fixing.

[0033] A further technical solution is to provide second ribs on both sides of the top of the main groove 2, which are parallel to the spring piece 3 and protrude into the main groove 2. The second ribs serve to slightly narrow the opening, so as to prevent the wire harness from moving up and down and coming off after the wire code is installed.

[0034] It is feasible that the second rib and the top wall of the main groove 2 are connected by a smooth arc transition to facilitate the insertion of the wire harness into the main groove 2;

[0035] In this embodiment, the main groove 2 is a semi-enclosed structure, which can play a temporary fixing role when the wire harness is arranged in the actual vehicle, solving the problem that the wire harness corrugated tube is too smooth and difficult to fix.

[0036] In some embodiments, after the spring piece 3 is provided, the extension and retraction of the spring piece 3 can be used to adapt to high voltage wire harnesses of different wire diameters. The spring piece 3 can be provided by setting a limiting groove on the inner wall of the main body groove 2 and the cover 4, with both ends of the spring piece 3 abutting against the inner wall of the limiting groove.

[0037] Optionally, multiple spring pieces 3 can be arranged in a symmetrical structure. The number of spring pieces can be set as needed. In one specific arrangement, one spring piece 3 is set on the inner wall of the cover 4 and two spring pieces 3 are set on the inner wall of the main body groove 2. The three spring pieces form an isosceles triangle to ensure the stability of the fixation.

[0038] In some embodiments, the insulated wire code further includes a bracket mounting structure for mounting the wire code bracket 7. The bracket mounting structure includes an insertion hole 1 provided on the wire code body. An elastic locking structure 8 is provided in the insertion hole 1. The elastic locking structure 8 is configured as an elastic suspension piece. A triangular protrusion is provided on the elastic suspension piece. The triangular protrusion is adapted to the triangular groove on the wire code bracket.

[0039] like Figure 1 and Figure 2As shown, the wire code bracket 7 is inserted into the insertion hole 1. During insertion, the suspension piece of the elastic locking structure 8 is pressed down, thus providing a receiving space for the wire code bracket 7. When the triangular groove reaches the position of the triangular protrusion, the suspension piece of the elastic locking structure 8 springs upward, connecting the elastic locking structure 8 and the wire code bracket 7 together through elastic force. The portion of the elastic locking structure 8 exposed in the main body groove 2 can be manually pressed, thereby separating the elastic locking structure 8 from the wire code bracket 7 after pressing. In this embodiment, the elastic locking structure 8 is set in the form of a suspension piece, which can further improve the efficiency and convenience of assembling and disassembling the wire code on the bracket.

[0040] It is possible to use insulating material on the surface of the insulated wire code that contacts the wire harness.

[0041] The usage process of the above-mentioned insulating wire code is explained as follows:

[0042] The wire code bracket 7 is connected to the vehicle body. Before installing the wiring harness, the insulated wire code is first pre-installed on the wire code bracket 7. The insertion hole 1 of the insulated wire code base is connected to the wire code bracket 7. When the insertion is in place, the elastic locking structure 8 will lock the bracket to prevent the insulated wire code from moving.

[0043] After installing the insulated wire code onto the wire code bracket 7, confirm the reserved length of the high-voltage wire harness according to the positioning label, and place the wire harness into the main groove 2 of the insulated wire code. The main groove 2 can temporarily fix the high-voltage wire harness. If the length of the wire harness needs to be adjusted, the wire harness can be moved at this time. After the reserved length of the wire harness is confirmed, the cover 4 is fastened to the main groove 2. At the same time, the spring 3 located in the main groove 2 and the cover 4 will adjust the elasticity according to the different corrugated pipe outer diameters of the high-voltage wire to adapt to different corrugated pipe outer diameters. The larger the outer diameter, the greater the elasticity of the spring 3, and the more firmly the wire harness is fixed. There are 3 spring 3 in total, two in the main groove 2 and one in the cover 4. After the cover is closed, the 3 spring 3 will form an isosceles triangle structure to ensure that the wire harness is firmly fixed. Finally, the clamping plate 5 and the clamping slot 6 are closed to prevent the wire harness from moving left and right or up and down.

[0044] The insulated wire clips are also easy to remove. The elastic locking structure 8 is a suspended plate type. To remove them, simply push the suspended plate outward to allow the lock to avoid the bracket groove, and move the wire clip outward from the bracket to remove it. The insulated wire clips have a quick-install structure, which allows for rapid installation and avoids the need for bolt connections as with other wire clips. This reduces the complexity of the process, improves work efficiency, and lowers construction costs.

[0045] The insulated wire code of this embodiment has an insertion hole structure for easy installation onto the wire code bracket, an elastic locking structure 8 when the wire code is installed in a suitable position on the bracket, a wire fixing structure formed by the main body groove 2 and the cover 4 for fixing the high voltage wire harness, a buckle structure for preventing the wire harness from falling off, and a spring sheet structure that adapts to different wire diameters. This spring sheet can adjust its internal elasticity according to the outer diameter of different high voltage wire harnesses to fix the wire harness; it is especially suitable for fixing a single high voltage wire harness.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0047] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
