Description

Technical Field

[0001] This utility model relates to the technical field of automotive wiring, and more specifically, to an anti-corrosion structure for grounding wire harnesses. Background Technology

[0002] Grounding harnesses in automobiles are primarily used to connect the vehicle body to the negative terminal of the battery, and the engine and transmission to the negative terminal of the battery. They are divided into two types: body grounding harnesses and engine grounding harnesses. A body grounding harness connects the vehicle body to the negative terminal of the battery; an engine grounding harness connects the engine to the negative terminal of the battery (or the vehicle body itself).

[0003] Currently, grounding harnesses are susceptible to corrosion in applications such as automobiles and ships. However, the anti-corrosion structure of common automotive harnesses is usually integrated with the harness. When a portion of the anti-corrosion structure is heavily corroded, it is difficult to replace the corroded part. Replacing the entire anti-corrosion structure or the entire grounding harness is costly and not conducive to the reuse of the grounding harness.

[0004] Therefore, in view of this, we have studied and improved the existing structure to provide a corrosion-resistant structure for grounding wire harnesses, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an anti-corrosion structure for grounding wire harnesses. It can achieve anti-corrosion wrapping of grounding wire harnesses, facilitate the bending and laying of grounding wire harnesses, and eliminate the need to replace the entire anti-corrosion structure or the entire grounding wire harness when corrosion occurs, thereby reducing the cost of using grounding wire harnesses and realizing the reuse of grounding wire harnesses.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A corrosion-resistant structure for grounding wire harness includes a corrosion-resistant skin wrapped around the outside of the grounding wire harness, and a plurality of clamping components are provided on the outside of the corrosion-resistant skin, with the clamping components being adjacent to each other and tightly fitted together.

[0010] The clamping assembly consists of a clamp head, a connecting mesh, and a clamp tail. The clamp head and clamp tail have the same structure. The clamp head consists of a left half-circle and a right half-circle. The bottom ends of the left half-circle and the right half-circle form a hinge structure. The bottom ends of the left half-circle and the top ends of the right half-circle are close together and are fitted with locking bolts.

[0011] Furthermore, the anti-corrosion coating is wrapped around the outside of the grounding wire harness in a coiled manner, and the number of coils of the anti-corrosion coating is not less than two layers.

[0012] Furthermore, the top and bottom of the left half-circle are provided with strip-shaped slots, and both strip-shaped slots are located on one side of the inner circle of the left half-circle.

[0013] Furthermore, the top and bottom ends of the right half-circle are fixedly installed with locking strips, which are inserted into the corresponding strip-shaped slots;

[0014] Both strip-shaped slots are located on the inner side of the right half of the circle.

[0015] Furthermore, a plate is fixedly installed at the top of both the left and right halves of the ring. A threaded hole is provided on the inner side of the plate on the left half of the ring, and the threaded hole is threadedly connected to the locking bolt.

[0016] Furthermore, a sliding hole is provided on the inner side of the plate located on the right half of the circle, and the diameter of the sliding hole is equal to the diameter of the threaded hole.

[0017] Furthermore, the connecting mesh is composed of twenty-four aluminum alloy wires and six aluminum alloy arc-shaped wires;

[0018] The number of aluminum alloy wires distributed at the bottom of the left half circle and on the right half circle is twelve each, and the number of aluminum alloy arc wires distributed at the bottom of the left half circle and on the right half circle is three each.

[0019] The same aluminum alloy curved wire is fixed simultaneously with twelve aluminum alloy wire strips.

[0020] 3. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] In this solution, the grounding wire harness is protected against corrosion by an anti-corrosion structure, which consists of an anti-corrosion sheath and clamping components. The anti-corrosion sheath is wrapped around the outside of the grounding wire harness in a coiled manner, and multiple clamping components are used to tighten the outside of the anti-corrosion sheath, thus achieving anti-corrosion wrapping of the grounding wire harness. At the same time, since aluminum alloy wires and aluminum alloy curved wires can be deformed to a certain extent, it is convenient to bend and lay the grounding wire harness.

[0023] When a significant amount of corrosion occurs in the anti-corrosion structure, only the anti-corrosion coating and clamping components in the corroded areas need to be replaced. In this case, it is not necessary to replace the entire anti-corrosion structure or the entire grounding harness, which reduces the cost of using the grounding harness and enables its reuse.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] Please see Figure 1 - Figure 4 A corrosion-resistant structure for grounding wire harness includes a corrosion-resistant skin 2 wrapped around the outside of the grounding wire harness 1, and a plurality of clamping components 3 are provided on the outside of the corrosion-resistant skin 2, with the clamping components 3 being adjacent to each other and tightly fitted together.

[0038] The clamping assembly 3 consists of a clamp head 301, a connecting mesh 302, and a clamp tail 303. The clamp head 301 and the clamp tail 303 have the same structure. The clamp head 301 consists of a left half-circle 3011 and a right half-circle 3012. A hinge structure is formed between the bottom end of the left half-circle 3011 and the bottom end of the right half-circle 3012. The bottom end of the left half-circle 3011 and the top end of the right half-circle 3012 are close together and are fitted with locking bolts 3013.

[0039] See Figure 1 , Figure 2 Specifically, the anti-corrosion skin 2 is wrapped around the outside of the grounding wire harness 1 in a coiled manner, and the number of coils of the anti-corrosion skin 2 is not less than two layers.

[0040] The length of a single section of the anti-corrosion skin 2 only needs to be greater than the length of a single clamping component 3. The two-layer winding method can avoid the presence of anti-corrosion dead corners on the outside of the grounding wire harness 1.

[0041] See Figure 1 , Figure 3 , Figure 4 Specifically, the top and bottom of the left half-circle 3011 are provided with strip-shaped slots 3014, and both strip-shaped slots 3014 are located on the inner side of the left half-circle 3011.

[0042] Specifically, the top and bottom of the right half-circle 3012 are fixedly installed with a retaining strip 3015, which is inserted into the corresponding strip slot 3014.

[0043] Both strip-shaped slots 3014 are located on one side of the inner ring of the right half-circle 3012.

[0044] When the left half-circle 3011 and the right half-circle 3012 are pressed together, the locking strip 3015 is inserted into the strip groove 3014. After the left half-circle 3011 and the right half-circle 3012 are locked, a hoop structure can be formed between the left half-circle 3011 and the right half-circle 3012. Then, the locking relationship between the locking strip 3015 and the strip groove 3014 can enhance the fixing effect of the left half-circle 3011 and the right half-circle 3012 on the anti-corrosion skin 2.

[0045] See Figure 1 , Figure 3 , Figure 4 Specifically, a plate 3016 is fixedly installed at the top of the left half-circle 3011 and the top of the right half-circle 3012. A threaded hole 3017 is opened on the inner side of the plate 3016 on the left half-circle 3011, and the threaded hole 3017 is threadedly connected to the locking bolt 3013.

[0046] Specifically, a sliding hole is provided on the inner side of the plate 3016 located on the right half circle 3012, and the diameter of the sliding hole is equal to the diameter of the threaded hole 3017.

[0047] Locking between the two plates 3016 is achieved by passing a locking bolt 3013 through the sliding hole and locking it with the threaded hole 3017.

[0048] See Figure 3 , Figure 4Specifically, the connecting mesh 302 is composed of twenty-four aluminum alloy wires 3021 and six aluminum alloy arc wires 3022;

[0049] The number of aluminum alloy wires 3021 distributed at the bottom of the left half circle 3011 and on the right half circle 3012 is twelve each, and the number of aluminum alloy arc wires 3022 distributed at the bottom of the left half circle 3011 and on the right half circle 3012 is three each.

[0050] The same aluminum alloy curved wire 3022 and twelve aluminum alloy wire strips 3021 are fixed at the same time.

[0051] Both aluminum alloy wire strip 3021 and aluminum alloy curved wire 3022 are aluminum alloy wires, which have high corrosion resistance. The aluminum alloy wire strip 3021 and aluminum alloy curved wire 3022 form a mesh structure connecting net 302, which can effectively bind the anti-corrosion skin 2 inside the connecting net 302, ensuring that the anti-corrosion skin 2 tightly wraps the grounding wire harness 1. At the same time, both aluminum alloy wire strip 3021 and aluminum alloy curved wire 3022 can be deformed freely to a certain extent, which facilitates the bending and laying of the grounding wire harness 1.

[0052] Working principle:

[0053] The anti-corrosion structure consists of an anti-corrosion sheath 2 (a common wire harness anti-corrosion sheath material, which will not be described in detail here) and a clamping assembly 3. When the grounding wire harness 1 is in use, the anti-corrosion sheath 2 is wrapped around the outside of the grounding wire harness 1 in a coiled manner, and the number of coils of the anti-corrosion sheath 2 is not less than two layers. At this time, the clamp head 301 and clamp tail 3 of the clamping assembly 3 are both put on the outside of the anti-corrosion sheath 2.

[0054] Then, the clamp head 301 is locked. Specifically, the clamp head 301 rotates through the hinge structure, causing the left half-circle 3011 and the right half-circle 3012 to close. At this time, the locking strip 3015 is inserted into the strip-shaped locking groove 3014, and a clamp ring structure can be formed between the left half-circle 3011 and the right half-circle 3012. Then, a locking bolt 3013 passes through the sliding hole and is threadedly locked with the threaded hole 3017, thereby achieving the locking between the two plates 3016.

[0055] Then, pull the position of the hoop tail 303 to tighten the connecting net 302, and then lock the hoop tail 303. The locking method of the hoop tail 303 is the same as that of the hoop head 301.

[0056] Repeat the above steps to tighten the outer side of the anti-corrosion skin 2 with multiple clamping components 3. In this way, the grounding wire harness 1 can be wrapped with anti-corrosion coating. At the same time, since the aluminum alloy wire strip 3021 and the aluminum alloy arc wire 3022 can be deformed to a certain extent, it is convenient to bend and lay the grounding wire harness 1.

[0057] Secondly, when a significant amount of corrosion occurs in the anti-corrosion structure, the anti-corrosion sheet 2 and clamping component 3 in the corroded part can be replaced. In this case, it is not necessary to replace the entire anti-corrosion structure or the entire grounding harness 1, which reduces the usage cost of the grounding harness 1 and enables the reuse of the grounding harness 1.

[0058] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
