Description

Technical Field

[0001] The utility model relates to the technical field of wire harness sheaths, in particular to a punched hole waterproof wire harness sealing sheath. Background Art

[0002] The power supply of the vehicle's external electrical appliances requires the wiring harness to be led out from the body, and the through-hole wiring harness is a part that assists the wiring harness assembly to pass through the holes in the body or vehicle panels. The through-hole wiring harness can prevent the wiring harness from colliding and wearing with the wall holes, and can also play a role in waterproofing, dustproofing and noise isolation.

[0003] Existing wiring harness sheaths are generally applied to the sheet metal hole sealing of the vehicle by gluing. After long-term use, the colloid that fixes the wiring harness sheath is prone to cracking, causing the wiring harness sheath to fall off, resulting in failure of the sheet metal hole sealing, water seepage, leakage, etc., which will cause corrosion to the decorative parts in the vehicle, which is very inconvenient. Utility Model Content

[0004] Based on the above description, the utility model provides a punched waterproof harness sealing sheath to solve the problem that the existing harness sheath is easily aged and falls off in the installation method of fixing it with glue.

[0005] The utility model solves the above-mentioned technical problem through the following technical scheme: a through-punch waterproof wire harness sealing sheath, comprising a sealing cover body and a sealing cover neck arranged on the top of the sealing cover body, a plug-in is arranged at the bottom of the sealing cover body, a wire groove with structural splitting and size adjustment is arranged on the outside of the plug-in, a closed groove is arranged on the outside of the plug-in, a ratchet which can be adjusted inside and outside the plug-in is arranged in the closed groove, and the ratchet is fixed to the sheet metal hole by snapping.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the sealing cover body is conical, the sealing cover neck is arranged at the end of the sealing cover body with a smaller diameter, and an annular groove is arranged on the outer side of the sealing cover neck.

[0008] Furthermore, the plug-in is composed of an insert ring, which is arranged at the end of the sealing cover with a larger diameter, and the wire grooves are opened on the outside of the insert ring and are distributed in a circular shape with equal distances around the center of the insert ring.

[0009] Furthermore, the closed grooves are arranged at equal distances on the outside of the insert ring and are located between two adjacent wire grooves.

[0010] Furthermore, the ratchet is installed at the bottom of the inner wall of the closed groove, the top of the ratchet faces the top of the closed groove, and extends obliquely to the outside of the insert ring.

[0011] Furthermore, a cable tie is installed in the annular groove, a sealing member is installed in the sealing cover neck, and a wiring hole is opened through the top of the sealing member.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model uses an insert ring and a wire groove, in conjunction with a closed groove and a ratchet. Under the setting of the wire groove, the insert ring is divided into a plurality of arc-shaped petals, which can be gathered together to adjust the diameter of the insert ring when inserted and installed, so that the insert ring is convenient to insert into the sheet metal hole for installation. The inserted insert ring can be buckled and fixed with sheet metal holes of different thicknesses through ratchets at different positions on the outside. The ratchets located on the inside of the sheet metal hole can be received in the closed groove without affecting the fixation of the wire harness sheath, thereby ensuring the fixing strength of the wire harness sheath and avoiding the wire harness sheath from falling off in the sheet metal hole due to aging, resulting in sealing failure. At the same time, with the gathering adjustment of the insert ring, the wire harness sheath can be repeatedly disassembled and assembled, which is convenient for the staff to subsequently adjust the disassembly and assembly without affecting the fixing strength of the wire harness sheath.

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] See also Figure 1-4 The utility model discloses a through-punch waterproof harness sealing sheath, comprising a sealing cover body 1 and a sealing cover neck 2 arranged on the top of the sealing cover body 1, a plug-in is arranged at the bottom of the sealing cover body 1, a wire groove 51 with a structure split and used for size adjustment is arranged on the outside of the plug-in, a closed groove 52 is arranged on the outside of the plug-in, a ratchet 6 that can be movably adjusted inside and outside the plug-in is arranged in the closed groove 52, and the ratchet 6 is fixed to the sheet metal hole by buckling.

[0023] The sealing cover body 1 is conical, and the sealing cover neck 2 is arranged at the end of the sealing cover body 1 with a smaller diameter. An annular groove 21 is arranged on the outer side of the sealing cover neck 2. The plug-in is composed of an insert ring 5, and the insert ring 5 is arranged at the end of the sealing cover body 1 with a larger diameter. The wire groove 51 is opened on the outer side of the insert ring 5 and is distributed in a circular shape with the center of the insert ring 5 as the center point. The opening of the wire groove 51 divides the insert ring 5 into a plurality of arc-shaped petals, and the separated arc-shaped petals can gather and diffuse each other. When the sealing cover body 1 is installed with the sheet metal hole through the insert ring 5, the insert ring 5 can be gathered through the wire groove 51 first, so that the insert ring 5 is smaller than the sheet metal hole, and then inserted into the sheet metal hole. After loosening, the insert ring 5 can be restored to its original size and installed with the sheet metal hole, which is convenient for the installation and use of the insert ring 5.

[0024] The closed grooves 52 are equidistantly arranged on the outside of the plug ring 5 and are located between two adjacent wire grooves 51. The ratchet 6 is installed at the bottom of the inner wall of the closed groove 52. The top of the ratchet 6 faces the top of the closed groove 52 and extends obliquely to the outside of the plug ring 5. The ratchet 6 extends obliquely to the outside of the closed groove 52 in a normal state. When the plug ring 5 is inserted into the sheet metal hole, the ratchet 6 can be buckled on the outside of the sheet metal hole to form a fixation, and the ratchet 6 located in the sheet metal hole can be folded into the closed groove 52, which does not affect the plug-in installation of the plug ring 5 and the sheet metal hole. The equidistant distribution of the ratchet 6 allows the plug ring 5 to be installed with sheet metal holes of different sizes.

[0025] A cable tie 3 is installed in the annular groove 21, a seal 4 is installed in the sealing cover neck 2, a wire hole 41 is opened through the top of the seal 4, the seal 4 is a rubber part, the wire hole 41 can pass a single wire harness for sealing, the cable tie 3 can fasten the sealing cover neck 2 and the seal 4, ensure that the wire harness in the wire hole 41 is tightly fitted with the seal 4, so that the sealing cover body 1 produces a sealing effect.
