Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing, in particular to a water splash-proof wire harness fixing device. Background Art

[0002] Wire harness holders are widely used in wiring fixation of various electrical systems. The main function of the wire harness holder is to fix the wire harness to a specific structure to prevent the wire harness from moving or rubbing during the operation of the equipment, thereby avoiding damage or breakage of the wire harness.

[0003] Traditional wire harness holders usually adopt an integrated structure, including a threading body and a sealing ring. The threading body is provided with a threading hole for threading the wire harness. The sealing ring is sleeved on the threading body to seal the gap between the wire harness and the threading body to prevent water or dust from entering the wire harness.

[0004] However, the wire harness holder in the prior art has the following problems:

[0005] Poor sealing performance: Due to the limitation of the integrated structure, the matching accuracy between the sealing ring and the threading body is low, which easily leads to gaps, resulting in reduced sealing performance and failure to effectively prevent water or dust from entering the wiring harness.

[0006] Inconvenient installation: Existing wire harness holders usually adopt a snap-on installation method, which requires the wire harness to pass through the threading hole and then snap into the snap, which is inconvenient to operate and inefficient.

[0007] Poor applicability: The diameters of wire harnesses of different devices are different. Existing wire harness holders are usually only suitable for wire harnesses of specific diameters and cannot achieve universal installation.

[0008] Low reliability: Existing harness holders are prone to loosening or falling off during equipment operation, and cannot ensure reliable fixation of the harness.

[0009] Therefore, it is necessary to provide a wire harness holder with simple structure, good sealing performance, convenient installation, strong applicability and high reliability to solve the problems existing in the prior art. Utility Model Content

[0010] In order to solve the problems of poor sealing, inconvenient installation, poor applicability and low reliability in the prior art, the utility model provides a splash-proof wire harness holder.

The first cavity is connected to the second cavity through the circular connection module. The circular connection module includes an inner ring and an outer ring, and the diameter of the inner ring is equal to the diameter of the first cavity.

[0016] Furthermore, the threading main body unit also includes a mounting seat, and the mounting seat is arranged on the inner wall of the circular connection module.

[0017] Specifically, the mounting seat is a rectangular mounting seat, comprising two side plates and a connecting rod, the two side plates are arranged on the inner wall of the circular connection module, and the connecting rod connects the two side plates.

[0018] Furthermore, the movable connection unit is installed on the mounting seat by means of a snap connection.

[0019] Preferably, the sealing unit is a rubber sealing sheet.

[0020] In addition, the utility model further comprises a second locking unit, which is movably fixed on the outer wall of the threading main body unit and can move axially along the outer wall of the threading main body unit.

[0021] Furthermore, the first locking unit is a cylindrical cavity that penetrates from top to bottom, with threads provided on the outer wall and a protrusion provided on one end.

[0022] The utility model can achieve the following beneficial effects:

[0023] The utility model provides a splash-proof harness fixture, which effectively solves the problem of poor sealing performance in the prior art by providing an independent sealing unit, an active connection unit and a first locking unit. The sealing unit is made of elastic rubber material, is reliably fixed to the active connection unit, and can realize axial movement in the threading main unit. Through the fastening and support of the first locking unit, not only the matching accuracy between the sealing unit and the threading main unit is improved, but also the harness can be tightly wrapped, effectively preventing water or dust from entering the interior of the harness, thereby improving the sealing protection performance of the harness fixture.

[0024] In addition, the utility model adopts the design of a movable connection unit and a locking unit, making the installation of the harness holder more convenient and quick. The movable connection unit is connected to the mounting seat of the threading main unit through a snap-on structure that is easy to assemble and disassemble quickly, and the position can be flexibly adjusted. The locking unit is reliably fixed to the threading main unit by a threaded connection, and can be locked or released by a simple rotation operation. These designs not only improve the installation efficiency, but also provide convenience for subsequent maintenance and replacement, saving time and labor costs.

[0025] At the same time, the utility model provides a first cavity and a second cavity of different diameters, as well as an adjustable movable connection unit and a locking unit, so that the harness holder can be applied to harnesses of different diameters, greatly enhancing its scope of application. The two-stage design of the first cavity and the second cavity can be flexibly selected according to actual needs, and is convenient for matching harnesses of different specifications. The movable connection unit and the locking unit can adjust the position and locking force within a certain range, further improving the adaptability to different harnesses and making it have a wider range of application scenarios.

[0026] In addition, the utility model makes full use of the functions of the first locking unit and the second locking unit to ensure the reliable fixation of the wire harness during the operation of the equipment, and significantly improves the reliability of the wire harness fixture. The first locking unit is arranged on the inner wall of the threading main unit, and can stably support the movable connection unit through threaded connection and axial movement to prevent it from shaking or falling off. The second locking unit is arranged on the outer wall of the threading main unit, and can firmly lock the entire fixture on the equipment installation hole, effectively resisting external vibration and impact, and ensuring that the wire harness can still be stably and reliably fixed under harsh working conditions.

[0027] In summary, the splash-proof wire harness holder provided by the utility model has many advantages, such as simple structure, good sealing performance, convenient installation, strong applicability and high reliability, by virtue of its unique structural design and excellent performance. It effectively solves the problems existing in the prior art, such as poor sealing, inconvenient installation, narrow scope of application, low reliability, etc., and is of great significance for improving the performance and ease of use of the wire harness holder.
