Wire harness sealing structure for meeting IP68 protection grade of fault indicator

Abstract

The utility model relates to a wire harness sealing structure for meeting the IP68 protection grade of a fault indicator, which comprises a main shell, a wire harness, polyurethane glue, a protective cover and screws, and is characterized in that the protective cover 4 presses the wire harness 2 into the polyurethane glue 3 through peripheral ribs 4.1, so that the IP68 protection inside and outside the main shell is realized. The wire harness sealing structure solves the problem of glue leakage of a traditional rubber sealing structure, and is high in reliability, simple to assemble and operate and low in cost.

Description

Technical Field

[0001] This utility model relates to the field of fault indicators, and in particular to a wire harness sealing structure for meeting the IP68 protection level of fault indicators. Background Technology

[0002] Fault indicators primarily measure the current in overhead lines using Rogowski coils. These coils consist of upper and lower Rogowski coils, which are connected via a wiring harness. The fault indicator requires IP68 protection. Existing wiring harness sealing structures include gland seals and rubber ring potting seals. Gland seals are costly and require a certain torque to ensure a tight seal. Rubber ring potting seals are complex to manufacture and often carry the risk of leakage. This invention designs a wiring harness sealing structure that uses a plastic reinforcing rib to seal the wiring harness within polyurethane adhesive, achieving IP68 protection for the fault indicator. Utility Model Content

[0003] This invention addresses the deficiencies and shortcomings of existing technologies by achieving IP68 protection level sealing for wiring harnesses in fault indicators. Using this structure, the product's IP68 protection level requirement is met, and the risk of adhesive leakage during manufacturing is eliminated. This wiring harness sealing structure is simple to operate, low in cost, and offers high sealing reliability.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A wire harness sealing structure for meeting the IP68 protection rating of a fault indicator comprises five parts: a main housing, a wire harness, polyurethane adhesive, a protective cover, and screws.

[0006] The upper protective cover is fixed to the main housing with four screws; the protective cover and part of the wiring harness are in polyurethane adhesive; the polyurethane adhesive covers the perimeter ribs of the protective cover and is lower than the height of the through-hole ribs and the potting ribs of the main housing.

[0007] Furthermore, the ribs around the protective cover serve a sealing function.

[0008] Furthermore, the two rings of ribs in the main shell serve to store polyurethane adhesive.

[0009] Furthermore, the through-hole rib of the main housing is a through hole, through which the wire harness enters the interior of the main housing.

[0010] Furthermore, a portion of the wiring harness serves as a sealant within the polyurethane adhesive.

[0011] The IP68 protected wire harness sealing structure of this utility model solves the problem of leakage risk of traditional rubber sleeve sealing structure. The modified sealing structure is simple, highly reliable and low cost. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 2 As shown, this utility model is a wire harness sealing structure for meeting the IP68 protection level of a fault indicator, including a main housing 1, a wire harness 2, polyurethane adhesive 3, a protective cover 4, and screws 5; the main housing 1 and the protective cover 4 are fixed together by four screws 5.

[0019] The through-hole rib 1.1 of the main housing 1 is a through hole through which the wire harness 2 enters the interior of the main housing 1; the through-hole rib 1.1 has a U-shaped groove 1.2 structure, which serves to hold the wire harness; the through-hole rib 1.1, the glue-filled bottom surface 1.3, and the glue-filled rib 1.4 of the main housing 1 form a cavity, which serves to store the polyurethane glue 3; the glue-filled rib 1.4 has a U-shaped groove 1.5 structure, which serves to hold the wire harness.

[0020] The ribs 4.1 around the protective cover 4 press the wire harness 2 into the polyurethane adhesive 3, achieving IP68 protection and sealing between the inside and outside of the main housing 1.

[0021] The above description is only one embodiment of the present utility model, and not all embodiments. Therefore, it does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
