As automation develops, the electronics industry also progresses, and the application range of wire harness terminals is becoming wider and wider, with more and more types.

[0003] Chinese patent CN220086519U discloses an automotive wiring harness terminal structure. When connecting two wiring harness terminals, the connector block is simply inserted into the connector slot. The connector rod slides into the snap-fit ​​cylinder, and the annular snap-fit ​​block is locked in the snap-fit ​​groove. When the two wiring harness terminals are held and the outer ends are pulled outwards, the snap-fit ​​block will disengage from the snap-fit ​​groove, thereby achieving a quick separation effect. This design facilitates the rapid assembly of two wiring harness terminals.

[0004] In complex operating environments, such as humid, dusty, or corrosive environments, terminals are easily corroded, leading to poor contact or even short circuits, which affects the normal operation of electrical equipment. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that in complex usage environments, such as humid, dusty, or corrosive gas environments, the terminals are easily corroded, leading to poor contact or even short circuits.

[0006] To address the aforementioned issues, this utility model provides a wire harness terminal housing, comprising a terminal, a wire harness fixedly connected to the side of the terminal, a protective cover that passes through the wire harness on the terminal, a side plate and a collar detachably connected to both ends of the protective cover, a sealing gasket fixedly connected to the end of the collar away from the side plate, multiple mounting blocks fixedly connected at equal intervals in a ring on the side wall of the sealing gasket, multiple damping telescopic rods detachably connected at equal intervals in a ring between the side plate and the collar, and the sealing gasket covering the outer surface of the damping telescopic rods, retaining rings symmetrically fixedly connected to both ends of the protective cover, and retaining grooves corresponding to the retaining rings being opened at the ends of the side plate and the collar, and the retaining rings engaging with the retaining grooves and being fixed by screws, a wire hole being opened in the middle of the side plate, and a sealing sleeve being connected to the side plate at the outer ring of the wire hole by screws, and the sealing sleeve being designed in multiple sizes.

[0007] In the aforementioned wire harness terminal housing, a detachable protective cover and a damping telescopic rod are installed to protect the terminals, preventing damage to the terminals in harsh environments and thus affecting their service life.

[0008] As a further improvement of this application, the side plate and the collar are symmetrically provided with multiple screw holes corresponding to the damping telescopic rod at one end, and the damping telescopic rod is threadedly connected to the screw holes, and a compression spring is sleeved on the surface of the damping telescopic rod.

[0009] As a further improvement of this application, the protective cover surface is detachably connected to two symmetrical clamps, and a cleaning brush is fixedly connected to the inner wall of the clamps, and the cleaning brush is in contact with the protective cover surface.

[0010] As a further improvement of this application, one of the clamp sidewalls is fixedly connected with a handle, and the clamp cross-section with the handle is symmetrically fixedly connected with a limit block.

[0011] As another improvement of this application, the other clamp has a groove symmetrically formed on its cross section, and the groove engages with the limiting block, and both the groove and the limiting block are made of magnetic materials that attract each other.

[0012] As a further improvement to this application, a vibration sensor and an alarm are fixedly connected to the damping telescopic rod, and a controller for the vibration sensor and the alarm is fixedly connected to one end of the side plate located inside the protective cover.

[0013] As a further improvement to this application, the protective cover is made of a transparent, foldable, waterproof material, and both the sealing sleeve and the inner wall of the slot are fixedly connected with sealing rings.

[0014] In summary, first, select a sealing sleeve with an inner diameter matching the cable harness and fix it to the side plate with screws. Then, put the protective cover over the terminal and cable harness. After inserting the terminal into the wiring port on the equipment, the sealing gasket will be in contact with the equipment, and a sealing sheet will be placed at the contact point. Then, fix the mounting block with screws to fix the protective cover on the equipment and cover the terminal surface. At this time, the sealing sleeve is tightly in contact with the cable harness surface through the sealing ring. When the terminal is used in a humid environment for a long time, it can seal and prevent corrosion. The damping telescopic rod and compression spring protect the terminal and prevent damage caused by collision and vibration of foreign objects. By setting a removable protective cover and damping telescopic rod, the terminal can be protected from damage in harsh environments, which can affect its service life. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figures 1-4 This diagram illustrates a wire harness terminal housing, comprising a terminal 1, a wire harness 2 fixedly connected to the side of the terminal 1, a protective cover 5 extending through the wire harness 2 onto the terminal 1, side plates 3 and collars 9 detachably connected to both ends of the protective cover 5, a sealing gasket 6 fixedly connected to the end of the collar 9 away from the side plate 3, a plurality of mounting blocks 7 equidistantly fixedly connected to the side wall of the sealing gasket 6, and a plurality of damping telescopic rods 10 detachably connected equidistantly between the side plates 3 and the collar 9, with the sealing gasket 6 covering the outer surface of the damping telescopic rods 10. The protective cover 5 has two ends facing... The device is fixedly connected with a retaining ring 8. The side plate 3 and the collar 9 are both provided with a retaining groove 11 corresponding to the retaining ring 8 at one end. The retaining ring 8 and the retaining groove 11 are engaged and fixed by screws. The side plate 3 has a wire hole 13 in the middle. The side plate 3 is connected to the outer ring of the wire hole 13 by screws. The sealing sleeve 4 is designed in multiple sizes. The protective cover 5 is made of transparent, foldable and waterproof material. The sealing sleeve 4 and the inner wall of the retaining groove 11 are fixedly connected with sealing rings. The surface of the damping telescopic rod 10 is fitted with a compression spring 12.

[0026] Working principle: First, select a sealing sleeve 4 with an inner diameter that matches the wire harness 2 and fix it to the side plate 3 with screws. Then, put the protective cover 5 on the terminal 1 and the wire harness 2. After inserting the terminal 1 into the wiring port on the equipment, the sealing gasket 6 is attached to the equipment, and a sealing sheet is placed at the attachment point. Then, fix the mounting block 7 with screws, thereby fixing the protective cover 5 on the equipment and covering the surface of the terminal 1. At this time, the sealing sleeve 4 is tightly attached to the surface of the wire harness 2 through the sealing ring. When the terminal 1 is used in a humid environment for a long time, it can be sealed and protected against corrosion. The damping telescopic rod 10 and the compression spring 12 protect the terminal 1 and prevent damage caused by collision and vibration of foreign objects to the terminal 1.

[0027] By setting a detachable protective cover 5 and a damping telescopic rod 10, the terminal 1 is protected, which can prevent the terminal 1 from being damaged in harsh environments and affecting its service life.

[0028] Second implementation method:

[0029] Figures 3-6 The side plate 3 and the collar 9 are symmetrically provided with multiple screw holes 14 corresponding to the damping telescopic rod 10 at one end, and the damping telescopic rod 10 is threaded to the screw holes 14. The protective cover 5 is detachably connected to two symmetrical clamps 15. A cleaning brush 16 is fixedly connected to the inner wall of the clamp 15 and contacts the surface of the protective cover 5. One clamp 15 has a handle 17 fixedly connected to its side wall. The clamp 15 with the handle 17 has a limit block 19 fixedly connected to its cross section symmetrically. The other clamp 15 has a groove 18 symmetrically provided on its cross section, and the groove 18 engages with the limit block 19. Both the groove 18 and the limit block 19 are made of magnetic material that attracts each other. A vibration sensor and an alarm are fixedly connected to the damping telescopic rod 10. The side plate 3 is located inside the protective cover 5 and a controller for the vibration sensor and the alarm is fixedly connected to one end.

[0030] Working principle: When terminal 1 is subjected to a strong impact from an external object, the vibration sensor detects the impact and sends a signal to the controller, which automatically activates the alarm to alert the staff to come and check. During the check, the two clamps 15 can be put on the surface of the protective cover 5 and fixed by the engagement of the groove 18 and the limit block 19. Then, the clamps 15 can be moved by holding the handle 17 to clean the dust on the surface of the protective cover 5. At this time, the inside can be viewed through the transparent protective cover 5. If the damping telescopic rod 10 is deformed by the impact, the protective cover 5 can be quickly removed and the deformed damping telescopic rod 10 can be twisted off and replaced.

[0031] Vibration sensors and alarms can promptly alert personnel to check when terminal 1 is impacted. Cleaning brush 16 can be used to clean dust from the surface of the protective cover 5, making it easy to check the condition of the internal terminal 1. Damping telescopic rods 10 that need to be replaced due to deformation can be removed and replaced individually.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
