Description

Technical Field

[0001] This application relates to the field of electronic and electrical connections, and in particular to integrated interface harness structures. Background Technology

[0002] The integrated interface harness structure integrates electrical connection components such as wires, connectors, and terminals through integrated design, combined with auxiliary components such as insulating sheaths and fixing brackets, to form a modular component with signal transmission, power supply, and mechanical protection functions. In order to meet the new demands of the automotive industry, the connector industry will continue to innovate technologically, as different car manufacturers and models have different requirements for connectors and more connector options.

[0003] However, traditional connector types (such as injection molding or non-detachable splicing) are prone to electrical performance failure due to vibration and displacement after assembly, which limits the flexibility of maintenance and adjustment and affects the overall reliability and service life of the connection. Utility Model Content

[0004] To address the issue that traditional connectors are prone to electrical performance failure due to vibration and displacement after assembly, this application provides an integrated interface harness structure.

[0005] The integrated interface harness structure provided in this application adopts the following technical solution:

[0006] The interface wire harness integrated structure includes a first card block and a second card block that is fixed at the lower end of the first card block. The first card block has symmetrical slots at both ends on one side, and the second card block has symmetrical protrusions fixed at both ends on one side that are fixed in the slots. A wire harness body first is fixed inside one end of the first card block and the second card block. A wire harness block is fixed inside the end of the first card block and the second card block away from the wire harness body first. Multiple wire harness bodies second that are welded and fixed to the wire harness body first are fixedly inserted into the internal array of the wire harness block.

[0007] By adopting the above technical solution, the first and second card blocks are tightly engaged through the hook-wedge structure of the slot and the protrusion, providing protection and fixed support for the internal wire harness; the end retaining ring and annular groove of the wire harness body are respectively embedded in the circular hole and arc groove formed by the first and second card blocks to achieve radial positioning and tensile fixation; the wire harness block is engaged in the elliptical groove of the first and second card blocks through the elliptical block and elliptical groove to guide the internal wire harness body; the wire harness body and the wire harness body are fixed inside the card blocks by welding to ensure the reliability of the electrical connection.

[0008] Preferably, both the first card block and the second card block have two ends, one large and one small. The smaller end of the first card block has multiple arc-shaped blocks fixed in an array, and the larger end of the first card block has symmetrically fixed semi-elliptical blocks. The smaller end of the second card block has multiple arc-shaped blocks that match the arc-shaped blocks, and the larger end of the second card block has symmetrically fixed semi-elliptical blocks that match the semi-elliptical blocks.

[0009] By adopting the above technical solution, the first and second locking blocks are interlocked by the matching arc-shaped blocks one and two at one end and the symmetrical semi-elliptical blocks one and two at the other end, achieving precise positioning and stable connection, thus ensuring the stable fixation of the wire harness and internal components.

[0010] Preferably, the first locking block has an arc groove between every two arc blocks, and the second locking block has an arc groove between each arc block. The arc blocks and the second arc blocks close together to form a block with a circular hole in the middle, and the arc grooves close together to form a complete circular groove.

[0011] By adopting the above technical solution, the first and second locking blocks are closed by the first and second arc-shaped blocks to form a block with a circular hole for fixing the first wire harness. At the same time, the first and second arc-shaped grooves are closed to form a complete circular groove, providing further support and positioning for the first wire harness.

[0012] Preferably, the first locking block is provided with a semi-elliptical groove between two semi-elliptical blocks, and the second locking block is provided with a semi-elliptical groove between two semi-elliptical blocks. The first and second semi-elliptical blocks are closed to form a block with an elliptical hole, and the first and second semi-elliptical grooves are closed to form a complete elliptical groove.

[0013] By adopting the above technical solution, the first and second locking blocks are closed by the semi-elliptical blocks to form a block with an elliptical hole for fixing components such as the wire harness block. At the same time, the semi-elliptical grooves are closed to form a complete elliptical groove, providing positioning and stable support for the wire harness block.

[0014] Preferably, one end of the wire harness body located inside the first and second locking blocks is fixedly fitted with a plurality of locking rings that are locked inside the first and second arc-shaped grooves. The wire harness body has a plurality of annular grooves on one side of the locking rings, and the first and second arc-shaped blocks are locked in the annular grooves.

[0015] By adopting the above technical solution, the retaining ring at one end of the wire harness body is initially fixed by being inserted into the arc-shaped groove formed by the closing of the first and second retaining blocks. At the same time, the annular groove on the wire harness body is fitted with the first retaining block and the arc-shaped block of the first retaining block. The double-clamping structure ensures that the wire harness body is stable and does not shift in the integrated structure of the interface wire harness.

[0016] Preferably, one end of the wire harness block located inside the first and second locking blocks is symmetrically fixed with an elliptical block that is locked in the semi-elliptical groove one and the semi-elliptical groove two. An elliptical groove is opened between the two elliptical blocks, and the semi-elliptical block one and the semi-elliptical block two are locked in the elliptical groove.

[0017] By adopting the above technical solution, the wire harness block is initially positioned by the end elliptical block being inserted into the semi-elliptical groove formed by the closure of the first and second locking blocks. At the same time, the elliptical groove on the wire harness block engages with the semi-elliptical block of the locking block to form a double locking structure, ensuring that the wire harness block is firmly fixed in the integrated interface wire harness structure.

[0018] Preferably, the protrusion is a wedge-shaped block with barbs, and the protrusion achieves a tight engagement between the first and second locking blocks through the barb structure.

[0019] By adopting the above technical solution, the barbed structure of the protrusion can be engaged into the corresponding slot and locked when the first and second locking blocks are closed, effectively preventing the first and second locking blocks from loosening.

[0020] Preferably, one end of the plurality of wire harness bodies 2 located inside the first and second locking blocks is fixed to the end of the first wire harness body 1 near the second wire harness body 2 by welding.

[0021] By adopting the above technical solution, the two ends of multiple wire harness bodies are permanently electrically connected to the corresponding ends of wire harness bodies by welding inside the first and second clamp blocks. The closed structure of the clamp block assembly provides support, anti-displacement, and dust protection for the welding points, ensuring the stability and reliability of signal transmission.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By pushing the second locking block into the first locking block, the barbed protrusions on both sides of the second locking block quickly align and engage with the slots of the first locking block. This causes the first arc-shaped block and the second arc-shaped block, as well as the first semi-elliptical block and the second semi-elliptical block, to close and form complete circular and elliptical locking holes, respectively. This stabilizes and secures the retaining ring on the first wire harness body and the elliptical block on the wire harness block. This structure is suitable for connector and wire harness combinations under different environmental conditions. It solves the problem of electrical performance failure that easily occurs under vibration and displacement in traditional injection-molded or non-removable splicing connectors, improves the flexibility of maintenance and adjustment, and makes the entire wire harness interface form a vibration-resistant and displacement-resistant integrated stable connection. This effectively ensures the reliability of the welding points, reduces fatigue damage to internal components of the wire harness caused by long-term vibration, extends service life, reduces manufacturing and operation difficulty and manufacturing costs, and improves mass production feasibility.
