Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, and in particular to a wire harness wiring device and an automotive antenna structure. Background Technology

[0002] As is well known, automotive AM / FM / DAB / TV antennas are usually located on the rear windshield and rear spoiler of a vehicle, and often integrate multiple antenna functions. In practical applications, the antenna located on the rear windshield can serve as the terminal for receiving signals in the entire vehicle. It can transmit signals to the antenna amplifier through the intermediate medium antenna connector, and then transmit them to the vehicle's central control unit.

[0003] Currently, the multiple functions of automotive antennas necessitate the antenna connector to have multiple pins, leading to the complexity and diversity of antenna connector designs. Traditional antenna connectors typically consist of multiple wire harnesses connected to the rear window antenna and spoiler antenna respectively. When the relevant antennas are far from the amplifier, longer wire harnesses are required for connection. In this case, due to mutual interference between various antenna signals, if two parallel antenna wire harnesses are too long, the installation posture of the antenna wire harnesses may become uncontrollable, and they may come into contact with each other.

[0004] Therefore, it is usually necessary to add a ribbon cable support connector between the two antenna harnesses to ensure that a certain distance is maintained between the two antenna harnesses. The antenna harnesses are usually purchased as standard harnesses, but the ribbon cable support connector will cause the harnesses to need to be customized or reprocessed.

[0005] Research has found that currently available cable support connectors typically include the following two types:

[0006] (1) Add a connecting rubber between the two antenna wire harnesses to ensure a certain gap between the two antenna wire harnesses; the length, width and position of the rubber on the antenna wire harness can be customized, but the customized connecting rubber is not universal and will increase the price cost several times.

[0007] (2) See Figure 1 As shown, an injection block is added between the two antenna wire harnesses to cover the two adjacent antenna wire harnesses. This solution requires an additional injection block mold, and the injection block needs to be 4mm thick. On the one hand, this will cause the connector to occupy more design space in the whole vehicle installation. On the other hand, this injection block will prevent the wire harness connector from being bent at will, which restricts the wiring path during installation.

[0008] It can be seen that the existing traditional technology has the following disadvantages: (1) It requires additional investment in molds and increases production processes, resulting in high manufacturing costs; (2) There are many design limitations, making it impossible to achieve design universality; (3) The process is complex; (4) It cannot flexibly realize the bending and routing of the wiring harness path, which limits the feasibility of installation on the whole vehicle. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a wire harness wiring device and an automotive antenna structure to solve the problems of complex process, high manufacturing cost and poor applicability of existing traditional solutions for automotive antenna wire harness wiring.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a wire harness wiring device, which includes a main support, and both ends of the main support in the length direction are provided with open slots. The open slots are arc-shaped open slots, the arc length of the open slots is 1 / 5 to 1 / 3 of the total arc circumference, and the diameter of the open slots is equal to the outer diameter of the insulation of the wire harness.

[0011] In the above technical solution, this utility model designs a new wire harness wiring device, which specifically has opening slots at both ends in the length direction of the main support, and the opening slots are set to be arc-shaped opening slots, so as to be used for antenna wire harnesses respectively. It is simple to install, and the manufacturing process is relatively simple and the manufacturing cost is low. In subsequent use, it can effectively match the existing wire harnesses as standard parts, so as to lock the standard wire harnesses in the opening slots, and use the main support to ensure the spacing between two adjacent wire harnesses.

[0012] To ensure the applicability of the aforementioned wire harness facilitator and its ease of use, this invention specifically limits the arc length of the opening slot to 1 / 5 to 1 / 3 of the total arc circumference. This ensures that the angle between the opening of the slot and its arc center is controlled within the range of 72° to 120°, facilitating the insertion and release of the wire harness from the facilitator. Furthermore, to ensure a secure locking effect and prevent the wire harness from easily detaching from the opening slot, in practical applications, the diameter of the opening slot is also controlled to be equal to the outer diameter of the wire harness insulation.

[0013] Therefore, the wire harness cable assemblies designed in this utility model can be understood as a universal structure clip. The opening slots at both ends can quickly snap into the corresponding positions of two adjacent antenna wire harnesses and limit the center distance between the two antenna wire harnesses to meet the antenna signal requirements. It is simple to manufacture, easy to install and has good versatility. It can be applied to a variety of antenna connectors.

[0014] Furthermore, in the wire harness wiring device of this utility model, the opening slot includes an arc-shaped slot portion and a guide portion, one end of the arc-shaped slot portion is connected to the guide portion, and the guide portion extends in a direction away from the arc center of the arc-shaped slot portion.

[0015] Furthermore, in the wire harness wiring device of this utility model, the arc-shaped slot is connected to a guide portion at each end of the main support in the thickness direction.

[0016] In the above-mentioned technical solution of this utility model, in order to facilitate installation and reduce the difficulty of inserting the antenna wire harness into the opening slot, a guide part can also be provided on the opening slot in practical applications. That is, the opening slot specifically includes an arc-shaped slot and a guide part. The arc-shaped slot is specifically used to accommodate the antenna wire harness, and one end of the arc-shaped slot can be connected to the guide part. The guide part can be extended away from the arc center of the arc-shaped slot to guide the installation and locking of the antenna wire harness by the guide part, thereby making it easy for the operator to quickly insert the arc-shaped slot of the wire harness connector into the antenna wire harness.

[0017] Furthermore, in the wire harness assembly described in this utility model, the distance between the ends of the two guide portions away from the arc-shaped groove in the opening groove is greater than the diameter of the arc-shaped groove.

[0018] In the above-mentioned technical solution of this utility model, the distance between the ends of the two guide parts away from the arc-shaped slot is greater than the diameter of the arc-shaped slot. This is to make it easier to let the antenna wire harness enter the distance between the two parts and enter the arc-shaped slot through the guiding function of the guide parts connected to the two ends of the arc-shaped slot in the thickness direction of the main support. This can greatly reduce the installation difficulty of the wire harness wiring device.

[0019] Furthermore, in the wire harness assembly described in this utility model, the distance between the two guide portions and the other end of the arc-shaped groove portion connected in the opening groove is less than the diameter of the arc-shaped groove portion.

[0020] In the above-mentioned technical solution of this utility model, controlling the distance between the two guide portions and the other end of the arc-shaped slot portion to be less than the diameter of the arc-shaped slot portion is to ensure the locking effect of the arc-shaped slot portion on the antenna wire harness and prevent the antenna wire harness from coming loose from the arc-shaped slot portion during subsequent use.

[0021] Furthermore, in the wire harness assembly of this utility model, the main bracket extends along a first direction, and the opening slot is provided through the main bracket along a second direction perpendicular to the first direction; wherein, the opening slots opened at both ends of the main bracket along the length direction are both oriented along the first direction, and the two opening slots are oriented in opposite directions.

[0022] Furthermore, in the wire harness wiring device described in this utility model, the main support is an elastic plastic frame.

[0023] In the above-mentioned technical solution of this utility model, in order to ensure the safety of the wire harness wiring harness, the main support needs to be specifically selected as an insulating frame; at the same time, in order to improve the applicability of the wire harness wiring harness, the main support can be specifically selected as an elastic plastic frame, which can flexibly adjust the position according to the actual assembly requirements while meeting the insulation requirements, and can be effectively applied to different antenna wire harness products.

[0024] Accordingly, this utility model also discloses an automotive antenna structure, which includes: multiple antenna harnesses and the above-mentioned harness wiring harness assembly of this utility model; wherein, the harness wiring harness assembly is disposed between two adjacent antenna harnesses.

[0025] Furthermore, in the automotive antenna structure described in this utility model, a plurality of the wire harness ribbon cables are arranged sequentially along the extension direction of the antenna wire harness and disposed between two adjacent antenna wire harnesses, and the two adjacent wire harness ribbon cables are spaced apart by a predetermined distance in the extension direction of the antenna wire harness.

[0026] Furthermore, in the automotive antenna structure described in this utility model, two adjacent antenna harnesses are respectively arranged to pass through the opening slots at both ends of the main bracket of the harness wiring harness along the length direction, and are engaged with the opening slots.

[0027] The beneficial effects of this utility model are as follows: This utility model designs a novel wire harness assembly, which has opening slots at both ends along the length of the main support, and these opening slots are set to be arc-shaped to accommodate antenna wire harnesses. Its manufacturing process is relatively simple and the manufacturing cost is low. In subsequent use, it can effectively match existing standard antenna wire harnesses to lock these standard antenna wire harnesses in the opening slots, and the main support is used to ensure the spacing between two adjacent antenna wire harnesses to meet the antenna signal requirements. It is easy to install and has good versatility, and can be applied to various antenna connectors. It has good prospects for promotion and application value. Attached Figure Description

[0035] 2. Antenna harness. Detailed Implementation

[0036] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] like Figures 2-5 As shown, in this embodiment, the present invention designs a new wire harness ribbon device 1, which is used in the automotive antenna structure to lock the spacing between two adjacent antenna wire harnesses in the automotive antenna wire harness structure.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the designed antenna harness structure may specifically include: multiple antenna harnesses 2 and the harness wiring device 1 described above; wherein, the harness wiring device 1 is disposed between two adjacent antenna harnesses 2, and the two adjacent antenna harnesses 2 can respectively pass through the opening slots 12 at both ends of the main support 11 of the harness wiring device 1 in the length direction.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, the designed wire harness 1 specifically includes a main support 11, and both ends of the main support 11 in the length direction are provided with opening slots 12. The opening slots 12 are specifically arc-shaped opening slots to accommodate the antenna wire harness 2. In practical applications, the arc length of the opening slot 12 can be specifically controlled to be 1 / 5 to 1 / 3 of the total arc circumference, and the diameter of the opening slot 12 is limited to be equal to the insulation outer diameter of the antenna wire harness 2.

[0040] It should be noted that the structure of the wire harness 1 is relatively simple, easy to install, and has a low manufacturing cost. In subsequent use, it can effectively match existing standard antenna harnesses 2 to lock them in the opening slot 12, and the main support 11 ensures the spacing between adjacent antenna harnesses 2. To ensure the wire harness 1 has good applicability and is convenient for users, the arc length of the opening slot 12 is limited to 1 / 5 to 1 / 3 of the total circumference. This ensures that the angle between the opening of the slot 12 and its arc center can be controlled within the range of 72° to 120°, facilitating the insertion of the antenna harness 2 or the release of the wire harness 1 from the antenna harness 2.

[0041] Of course, in order to ensure the locking effect and prevent the wire harness from easily coming loose from the opening slot 12 of the wire harness 1, in practical applications, the diameter of the opening slot 12 is also controlled to be equal to the outer diameter of the insulation of the antenna wire harness 1, so that the opening slot 12 can effectively match the antenna wire harness 2.

[0042] Based on this design, the wire harness ribbon cable 1 of this utility model can be specifically understood as a universal structure clip. The opening slots 12 at both ends of the wire harness ribbon cable 1 can quickly snap into the corresponding positions of two adjacent antenna wire harnesses 2, thereby limiting the center distance between the two antenna wire harnesses 2 to meet the antenna signal requirements. It has good versatility and can be applied to various antenna connectors to meet the needs of automotive antenna wiring.

[0043] It should be noted that in practical applications, the wire harness ribbon cable 1 can be made of a specific insulating material to meet insulation requirements. For example, the wire harness ribbon cable 1 can be made of elastic plastic material, that is, the main support 11 of the wire harness ribbon cable 1 can be made of elastic plastic frame, which can flexibly adjust the position according to actual assembly requirements and has insulation properties. This ensures the safety of the wire harness ribbon cable 1 and makes it convenient for users to match different types of antenna wire harnesses 2 during installation by utilizing the flexibility of the wire harness ribbon cable 1, thereby improving the applicability of the wire harness ribbon cable 1 and applying it to different types of antenna wire harness 2 products.

[0044] Accordingly, see further Figure 5As can be seen, in this embodiment, in order to facilitate installation and reduce the difficulty of inserting the antenna harness 2 into the opening slot 12, a guide portion 122 can also be provided on the opening slot 12 in practical applications. That is, the opening slot 12 specifically includes an arc-shaped slot portion 121 and a guide portion 122. The arc-shaped slot portion 121 is specifically used to accommodate the antenna harness 2, and one end of the arc-shaped slot portion 121 can be connected to the guide portion 122. The guide portion 122 can be extended in a direction away from the arc center of the arc-shaped slot portion 121, so as to guide the installation and locking of the antenna harness 2 by the guide portion 122, thereby making it easier for the operator to quickly insert the arc-shaped slot portion 121 of the harness wiring harness 1 into the antenna harness 2.

[0045] like Figure 5 As shown, in practical applications, both ends of the arc-shaped slot 121 of the wire harness wiring harness 1 in the thickness direction of the main support can be connected to a guide portion 122, and the distance d2 between the ends of the two guide portions 122 away from the arc-shaped slot 121 can be specifically controlled (e.g., ...). Figure 5 The diameter of the arc-shaped slot 121 is larger than that of the antenna harness 2, so that when the diameter of the arc-shaped slot 121 matches the outer diameter of the antenna harness 2, it is easier to let the antenna harness 2 enter the gap between the two and enter the arc-shaped slot 121 through the guidance of the two guides 122. This can greatly reduce the installation difficulty of the harness wiring device 1.

[0046] At the same time, such as Figure 5 As shown, in this embodiment, the distance d1 between the two guide portions 122 and the other end of the arc-shaped groove portion 121 can be further controlled (e.g., ...). Figure 5 The diameter of the arc-shaped slot 121 is smaller than that of the antenna harness 2, as shown, to ensure the locking effect of the arc-shaped slot 121 on the antenna harness 2 and to prevent the antenna harness 2 from coming loose from the arc-shaped slot 121 during subsequent use.

[0047] Accordingly, see Figure 2 , Figure 4 As shown, based on the above configuration, the matching and installation of the antenna harness 2 with the opening slot 12 of the harness wiring harness 1 designed in this invention can be greatly simplified; wherein, in practical applications, in order to ensure that the spacing between two adjacent antenna harnesses 2 after the harness wiring harness 1 is installed is uniform, the main support 11 can also be specifically controlled along the first direction (e.g., Figure 2 The opening groove 12 extends along a second direction perpendicular to the first direction (as shown in the X direction), and extends along a second direction perpendicular to the first direction (as shown in the X direction). Figure 2 The Y-direction shown is provided through the main support 11; wherein, the openings 12 at both ends of the main support 11 along the length direction are both oriented along the first direction, and the two openings 12 are oriented in opposite directions.

[0048] It should be noted that, as Figure 2 and Figure 4 As shown, in this embodiment, the first direction is specifically the extension direction of the main support 11, which is also the width direction of the wire harness 1; the second direction is specifically the length extension direction of the antenna wire harness 2 of the wire harness 1, that is, the length direction of the wire harness 1.

[0049] At the same time, such as Figure 2 As shown, in actual installation, to achieve better implementation results, multiple wire harness ribbon cables 1 can be arranged sequentially along the extension direction of the antenna wire harness 2, and these wire harness ribbon cables 1 can be positioned between two adjacent antenna wire harnesses 2, with a preset distance between adjacent wire harness ribbon cables 2 in the extension direction of the antenna wire harness 2. This preset distance can be adjusted according to the specific installation situation, and this invention does not impose any special limitations.

[0050] Based on this setup, it can be ensured that two adjacent antenna harnesses 2 pass through the opening slots 12 at both ends of the main bracket 11 of the harness wiring harness 1 along the length direction, and establish a snap-fit ​​engagement with the opening slots 12.

[0051] In summary, this utility model designs a novel wire harness 1, specifically with opening slots 12 at both ends of the main support 11 along its length. These opening slots 12 are arc-shaped and are used to accommodate antenna wire harnesses 2. The manufacturing process is relatively simple and the manufacturing cost is low. In subsequent use, the antenna wire harnesses 2 can be locked in the opening slots 12, and the main support 11 ensures the spacing between two adjacent antenna wire harnesses 2 to meet the antenna signal requirements. It is easy to install, has good versatility, and can be applied to various antenna connectors, showing good prospects for promotion and application value.
