Description

Technical Field

[0001] This utility model belongs to the field of wire harness technology, and in particular to a novel high-sealing wire harness. Background Technology

[0002] A wiring harness is a group of metal wires and cables bundled together, used for signal and power connections between transport equipment. It is a wiring component in automotive circuits that connects various electrical devices, consisting of an insulating sheath, terminals, wires, and insulating wrapping material. Existing wiring harnesses are designed with sealing devices for protection; however, if threaded connections are used, it can affect the performance of flat wiring harnesses, and the sealing performance is generally poor.

[0003] A search revealed a Chinese patent document (authorization announcement number CN213734858U) entitled "A Novel High-Sealing Wire Harness," comprising a conductor, a male buckle, and a female buckle. The outer surface of the conductor is fitted with a tubing, and a sealing mechanism is provided on the outside of the tubing. The sealing mechanism includes a first housing and a second housing. A first groove is formed on one side of the first housing, and a first through hole is formed on the other side. A second groove is formed on one side of the second housing, and a second through hole is formed on the other side. This utility model relates to the field of wire harness technology. This novel high-sealing wire harness, through the combined use of the first housing, second housing, first groove, first through hole, second groove, and second through hole, utilizes the threaded fixation between the first and second housings to enclose the male and female buckles, achieving a sealing effect. This solves the problem of gaps and poor sealing effects in existing male and female buckle insertion methods. While the aforementioned patent uses a threaded connection for sealing, this can affect the performance of flat wire harnesses, and the sealing performance is generally poor. Utility Model Content

[0004] The purpose of this invention is to provide a novel high-sealing wire harness to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel high-sealing wire harness, comprising: a flexible wire harness body, with a first connector and a second connector respectively connected to both sides of the wire harness body for mating; two protective tubes are also sleeved on the outer periphery of the wire harness body, and auxiliary plates are fixedly connected to the outer periphery of the protective tubes.

[0006] One of the auxiliary plates is connected to an outer sealing frame on its outer periphery, and the other auxiliary plate is connected to an inner sealing frame that is adapted to the outer sealing frame on its side. A high sealing sleeve that improves the sealing effect is bonded to the outer periphery of the inner sealing frame. A threaded channel is opened on the outer periphery of the outer sealing frame, and a T-shaped fixing threaded rod is threadedly connected to the threaded channel. The outer periphery of the inner sealing frame and the high sealing sleeve are provided with round holes for the fixing threaded rod to pass through.

[0007] In a preferred embodiment, the size of the inner sealing frame is larger than the size of the first connector and the second connector.

[0008] In a preferred embodiment, both protective tubes are connected to a winding rod on their outer periphery, and a pull rope is wound together around the outer periphery of both winding rods.

[0009] As a preferred embodiment, the actual length of the anti-pull rope is less than the length of the wire harness body, in order to prevent the wire harness body from being pulled by external force.

[0010] In a preferred embodiment, a rubber post is bonded to the top of the winding rod, and the outer diameter of the rubber post is larger than the outer diameter of the winding rod.

[0011] As a preferred embodiment, the outer periphery of the rubber column is fitted with a sleeve for protecting the winding rod, and the outer periphery of the sleeve has a notch for the anti-pull rope to pass through.

[0012] In a preferred embodiment, the outer periphery of the wire harness body is further fitted with a plurality of binding ropes for binding and restraining, and the high-sealing sleeve is made of rubber.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This new type of high-sealing wire harness, after the first connector and the second connector are connected and mated, inserts the inner sealing frame into the outer sealing frame and fixes it with a fixed threaded rod. Compared with the threaded connection, it has more stability. In addition, the outer periphery of the inner sealing frame is designed with an elastic high-sealing sleeve to further improve the sealing effect.

[0015] This new type of high-sealing wire harness, through the installation of an anti-pull rope, can prevent the wire harness body from being pulled straight and damaged by external forces. The anti-pull rope is wound and adjusted on the winding rod to meet the anti-pull requirements of different lengths. Through the installation of rubber posts and sleeves, the anti-pull rope on the winding rod can be protected.

The dimensions of the outer sealing frame 6 and the inner sealing frame 7 are adapted to the dimensions of the wire harness body 1, and are not based on the illustration. The dimensions of the inner sealing frame 7 are larger than the dimensions of the first connector 2 and the second connector 3, thereby meeting the assembly requirements. A high sealing sleeve 8 for improving the sealing effect is bonded to the outer periphery of the inner sealing frame 7. The high sealing sleeve 8 is made of rubber. The outer periphery of the outer sealing frame 6 has a threaded channel, and the threaded channel is threadedly connected to a T-shaped fixing threaded rod 9.

[0030] To prevent pulling and protect the wire harness, a winding rod 10 is connected to the outer periphery of each of the two protective tubes 4. A pull-resistant rope 11 is wound around the outer periphery of both winding rods 10. The actual length of the pull-resistant rope 11 is less than the length of the wire harness body 1 to prevent the wire harness body 1 from being pulled by external force. A rubber post 12 is glued to the top of the winding rod 10. The outer diameter of the rubber post 12 is larger than the outer diameter of the winding rod 10. A sleeve 13 for protecting the winding rod 10 is fitted around the outer periphery of the rubber post 12.

The winding degree of the pull-resistant rope 11 is adjusted, and then the sleeve 13 is fitted around the outer periphery of the rubber post 12. The pull-resistant rope 11 can prevent the wire harness body 1 from being pulled straight and damaged by external force.

[0031] The outer periphery of the wire harness body 1 is also fitted with a plurality of binding ropes 14 for binding and restraining.

[0032] Working principle

[0033] This new type of high-sealing wire harness, after the first connector 2 and the second connector 3 are connected and engaged, inserts the inner sealing frame 7 into the outer sealing frame 6 and fixes it with the fixing threaded rod 9 to achieve sealing;

[0034] Adjust the winding degree of the anti-pull rope 11, and then put the sleeve 13 on the outer periphery of the rubber column 12. The anti-pull rope 11 can prevent the wire harness body 1 from being pulled straight by external force and damaged.
