Description

Technical Field

[0001] The utility model relates to the technical field of wire harness sheaths, in particular to a waterproof wire harness sheath which is easy to install and prevents from falling off. Background Art

[0002] Existing wiring harness sheaths usually adopt a bellows structure, but relying solely on the bellows for protection, the overall strength is low and cannot withstand large extrusion pressure. At the same time, the overall sealing of the wiring harness sheath is poor, and it is not easy to seal at both ends, and the waterproof protection effect is not ideal.

[0003] Prior art CN220585910U discloses a waterproof wiring harness sheath that is easy to install and prevents from falling off, comprising a first corrugated tube, hard joints are fixedly installed at both ends of the first corrugated tube, and a second corrugated tube is sleeved on the outside of the first corrugated tube, a first wiring harness connector is arranged on the right side of the first corrugated tube, and a second wiring harness connector is arranged on the left side of the first corrugated tube, and connecting tubes are fixedly installed at the proximal ends of the first wiring harness connector and the second wiring harness connector, and a sealing plate is arranged at the outer end of the hard joint. The waterproof wiring harness sheath that is easy to install and prevents from falling off can improve the overall strength of the wiring harness sheath, enhance the ability to resist extrusion and deformation, and improve the protection effect on the wiring harness by arranging a hard protective structure composed of a movable ring and a connecting rod on the outside of the first corrugated tube of the wiring harness sheath body, and the two ends of the wiring harness sheath can be sealed and connected to the wiring harness connectors, thereby increasing the service life of the internal wiring harness, and the disassembly is convenient and quick.

[0004] However, when the above-mentioned waterproof wire harness sheath which is easy to install and prevent from falling off is actually used, the wire harness is used in angle setting and in straight line setting. When the wire harness needs to be used at an angle, the prior art can undergo a certain deformation to facilitate the setting of the wire harness. However, when the wire harness is set in a straight line, its connecting rods are arranged at intervals around the outside of the corrugated tube, resulting in more directly exposed areas of the corrugated tube, and the strength of the corrugated tube itself is also relatively low, which greatly reduces the protective effect and stability of the wire harness.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] Embodiment 1:

[0023] like Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the overall structure of the waterproof harness sheath that is easy to install and prevent from falling off. Figure 2 is a schematic structural diagram of the lower sheath 101, Figure 3 is a schematic structural diagram of the upper sheath 102, Figure 4 It is a structural schematic diagram of the connecting screw 107. The utility model provides a waterproof wire harness sheath that is easy to install and prevent from falling off: it includes a lower sheath 101, an upper sheath 102 and an auxiliary device, the inner surface of the lower sheath 101 is provided with a lower insulating layer 103, the inner surface of the upper sheath 102 is provided with an upper insulating layer 104, the auxiliary device includes a first sealing gasket 105, a second sealing gasket 106, a connecting screw 107, an O-ring 108 and a stabilizing component, and the stabilizing component includes a fixing block 111 and a clamping block 112. The above scheme can be used to improve the protection effect and protection stability of the wire harness when the wire harness is set in a straight line. It can be understood that the above scheme can improve the protection effect and protection stability of the wire harness set in a straight line.

[0024] In this embodiment, the upper sleeve 102 is detachably connected to the lower sleeve 101 and is located above the lower sleeve 101. The upper sleeve 102 and the lower sleeve 101 respectively have semicircular cavities and are respectively stamped from thin steel plates to achieve lightweight. The sleeves can be limited by clamping so that the lower sleeve 101 is at the bottom.

[0025] The lower insulating layer 103 is disposed on the inner surface of the lower jacket 101, and the upper insulating layer 104 is disposed on the inner surface of the upper jacket 102; the lower insulating layer 103 and the upper insulating layer 104 can improve the insulation protection capability when protecting the wiring harness.

[0026] The first sealing gasket 105 is detachably connected to the lower sleeve 101 and is located on one side of the lower sleeve 101. The second sealing gasket 106 is detachably connected to the lower sleeve 101 and is located on a side of the lower sleeve 101 away from the first sealing gasket 105. The connecting screw 107 is detachably connected to the upper sleeve 102 and is threadedly connected to the lower sleeve 101 and is located on a side of the upper sleeve 102 close to the lower sleeve 101. The O-ring 108 is sleeved on the outside of the connecting screw 107, and the stabilizing components are respectively arranged on both sides of the lower sleeve 101 and the upper sleeve 102. Rectangular grooves are provided on both sides of the lower sheath 101 to facilitate direct installation of the first sealing gasket 105 and the second sealing gasket 106. A connecting threaded hole is provided on the lower sheath 101, and a limit platform structure is provided on the upper sheath 102 for installation and limitation of the connecting screw 107. The O-ring 108 can be directly sleeved on the outside of the connecting screw 107.
