Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of wire harness, and particularly relates to a wire harness fixing device. BACKGROUND

[0002] In today's many industrial and technological fields, wire harness fixing devices play a crucial role. Whether in the automotive manufacturing industry, to ensure the orderly layout and stable connection of various wire harnesses in the complex electrical system of the automobile, to avoid short circuit and other faults caused by wire harness shaking and displacement; or in the field of electronic equipment production, such as the regulation of internal fine wire harness of computer and mobile phone, to ensure the reliable and efficient signal transmission between electronic components; or in the power system, to maintain the safety fixation of a large number of high and low voltage wire harnesses in various harsh environments and electromagnetic interference in transformer substations and power stations, wire harness fixing devices are indispensable key components. It can effectively improve the stability and safety of the system, and facilitate the maintenance and repair work of the equipment.

[0003] However, many existing wire harness fixing devices have many limitations in practical application. For example, the structure of some traditional wire harness fixing devices is often simple, and single clips or simple slot forms are often used. The design of such simple structure can only bind and fix a single group of wire harnesses. When facing the situation of fixing multiple groups of wire harnesses at the same time, it is not enough. For example, in the electrical control cabinet of large-scale automated production line, there are often a large number of wire harnesses with different functions and directions. Since the existing simple structure wire harness fixing device cannot bind multiple groups of wire harnesses at the same time, it can only be fixed one by one, which not only leads to extremely tedious installation process, time-consuming and laborious, but also makes it difficult to ensure the neatness and stability of the fixed multiple groups of wire harnesses, which is easy to cause mutual entanglement and interference between wire harnesses, increases the probability of line fault, and seriously affects the normal operation and maintenance efficiency of the equipment. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a wire harness fixing device capable of binding multiple groups of wire harnesses at the same time to solve the problems mentioned in the background.

[0008] The first fixing assembly comprises:

[0009] The boss protrudes from the bottom of the fixing frame.

[0010] A plurality of through holes are arranged on the fixing frame and the boss in the front-rear and up-down directions.

[0011] A rolling belt is arranged between adjacent through holes, and the rolling belt cooperates with the through holes to bind the wire harness in the rolling belt.

[0012] The buckle assembly comprises:

[0013] A clamping block is arranged on the top of the connecting block, the clamping block is internally provided with a clamping groove, and an elastic positioning column is arranged in the clamping groove.

[0014] An outwardly buckling strip is arranged on one side of the clamping block, one side of the outwardly buckling strip is provided with a first barb, the clamping groove is internally provided with a second barb matched with the first barb, and the second barb and the elastic positioning column form a hook groove matched with the first barb.

[0015] The second fixing assembly comprises:

[0016] Fixing columns are symmetrically arranged on the bottom of the clamping block.

[0017] A fixing clamping groove is arranged on the top of the connecting block and matched with the fixing columns, and a third fixing assembly is arranged between the fixing clamping groove and the fixing columns.

[0018] The third fixing assembly comprises:

[0019] An elastic ring is sleeved on the fixing column, and a fixing clamping table for preventing the elastic ring from being separated from the fixing clamping groove is arranged in the clamping groove.

[0020] An elastic reset member is fixedly connected to the bottom of the fixing clamping groove at one end and abuts against the elastic ring at the other end.

[0021] The first barb and the second barb are made of magnetic materials that attract each other.

[0022] The fixing sheet is made of a shape memory alloy.

[0023] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0024] 1. Through the cooperation of the boss, multiple through holes and the strip in the first fixing component, the strip can be wound between adjacent through holes. By utilizing the synergistic effect of the through holes and the strip, multiple groups of wire harnesses can be stably bound in the strip, thereby realizing the simultaneous fixing of multiple groups of wire harnesses on the fixing frame. This greatly improves the convenience and stability of wire harness fixing, makes the wire harnesses neatly arranged in the fixing frame, and reduces the possibility of wire harnesses tangling and interfering with each other.

[0025] 2. In the snap-fit ​​assembly, the snap block has a slot and an elastic positioning post. A first barb is provided on one side of the outward-opening snap strip, and a second barb mates with the first barb within the slot. A hook groove is formed between the second barb and the elastic positioning post. When the outward-opening snap strip is engaged, the first barb engages with the hook groove. Furthermore, since the first and second barbs are made of mutually attracting magnetic materials, the tightness of the connection is further enhanced, making the snap-fit ​​assembly less prone to loosening after connection. This ensures the reliability of the connection between the fixing mechanisms and prevents the wire harness fixing device from failing due to loose connection.

[0026] 3. The fixing post of the second fixing component cooperates with the fixing slot at the top of the connecting block. Through the elastic ring, fixing plate, and elastic reset member in the third fixing component, the elastic ring is sleeved on the fixing post. Under the resistance of the elastic reset member at the bottom of the fixing slot, the fixing post is more firmly fixed in the fixing slot. At the same time, when disassembly is required, a certain external force can be applied to overcome the resistance of the elastic reset member, and the fixing post can be easily removed from the fixing slot. This improves the stability of the connection and facilitates operation, ensuring the stability of the connection between the components of the second fixing mechanism, and indirectly improving the reliability of the entire wire harness fixing device.

[0059] The clamping block 40 serves as the main bearing structure of the buckle assembly 4, and provides a basic framework for the clamping groove, the elastic positioning column 41 and the cooperation with the outwardly-upward buckle strip 42. It plays a role in integrating and positioning other related components, so that the buckle assembly 4 can realize stable connection and locking function, ensure the connection firmness between the connecting block 30 and other components, and further guarantee the structural stability of the whole wiring harness fixing device. The clamping block 40 is generally a block structure in the shape of a cuboid or a square, and has a hollow or recessed part inside to form a clamping groove. The clamping block 40 can be connected with the connecting block 30 through the second fixing assembly 5.

[0060] The elastic positioning column 41 plays a role in positioning and auxiliary locking in the clamping groove.

[0066] The fixed clamping groove 51 is arranged on the top of the connecting block 30 and cooperates with the fixed column 50, and the third fixing assembly 6 is arranged between the fixed clamping groove 51 and the fixed column 50.

[0067] The fixed column 50 is a key structural part for connecting the clamping block 40 and the connecting block 30, and bears the important task of transmitting force and keeping the relative position stable. It stably installs the clamping block 40 on the connecting block 30 through cooperation with the fixed clamping groove 51, ensures that the buckle assembly 4 does not displace or shake due to external force under various working conditions, thereby guaranteeing the structural integrity and reliability of the entire wiring harness fixing device, and enabling the wiring harness to be reliably fixed and protected.

[0070] Embodiment 5:

[0071] The wiring harness fixing device provided in the embodiment further has the following technical features in addition to the technical solutions of the above embodiments.

[0072] The third fixing assembly 6 comprises:

[0073] The elastic ring 60 is sleeved on the fixed column 50, and the fixed clamping groove 51 is provided with a fixed clamping groove 61 for preventing the elastic ring 60 from being pulled out of the fixed clamping groove 51;

[0074] The elastic reset member 62 is fixed to the bottom of the fixed clamping groove 51 at one end and abuts against the elastic ring 60 at the other end.

[0075] The elastic ring 60 is sleeved on the fixed column 50, and under the cooperation of the elastic reset member 62, a radial holding force is applied to the fixed column 50, thereby enhancing the stability of the fixed column 50 in the fixed clamping groove 51 and preventing loosening or displacement of the fixed column 50 due to external force. It can buffer the impact of external force to a certain extent, reduce the wear between the fixed column 50 and the fixed clamping groove 51, ensure the reliability and durability of the connection between the clamping block 40 and the connecting block 30, and further ensure the structural integrity and functional stability of the entire wiring harness fixing device. The elastic ring 60 is generally a circular ring structure so as to be sleeved on the fixed column 50. The elastic ring 60 is sleeved on the fixed column 50 through elastic deformation of the elastic ring 60, and forms a close contact with the fixed column 50.

The axial displacement is limited, and the elastic ring 60 interacts with the elastic reset member 62 to realize the holding function of the fixed column 50.

[0076] The elastic reset member 62 plays a role of energy storage and release. When the fixed column 50 is inserted into the fixed clamping groove 51, the elastic reset member 62 is compressed and stores elastic potential energy. When the external force disappears or decreases, the elastic reset member 62 releases the elastic potential energy and pushes the elastic ring 60 to return to the state of holding the fixed column 50, thereby ensuring the stable fixation of the fixed column 50 in the fixed clamping groove 51 and enhancing the reliability of the connection between the clamping block 40 and the connecting block 30. At the same time, it can also buffer the impact of external force on the connecting structure to a certain extent. The elastic reset member 62 is generally a spring or an elastic rubber block having elastic recovery capability. When a spring is used, one end can be fixed at the bottom of the fixed clamping groove 51 by welding, riveting or inlaying, and the other end is in contact with the elastic ring 60.

[0079] The first barb 43 and the second barb 44 are made of mutually attractive magnetic materials.

[0080] In the locked state, the mutual attraction of the first barb 43 and the second barb 44 can provide additional holding force. When the wiring harness fixing device is subjected to external force, such as vibration, collision or slight pulling during normal use, the magnetic attraction force can prevent the first barb 43 from accidentally coming out of the hook groove. For example, in the wiring harness fixing device in the engine compartment of a vehicle, continuous vibration will occur during vehicle driving, and the magnetic attraction force helps to maintain the locking of the clasp assembly 4, so that the wiring harness will not loosen due to vibration.
