Description

Utility model field [001] The present utility model is situated in the fields of engineering and agriculture. More specifically, the present utility model relates to a constructive arrangement in a cover for the protection of electrical connectors of agricultural machinery, ensuring protection against weathering and wear. Fundamentals of the utility model [002] Electrical connectors and cables are widely used in agricultural machinery to power the numerous components present, such as valves, actuators, motors, sensors, among others, which are fundamental to their operation. [003] During operation, cables and connectors are exposed to various environmental conditions, such as rain and humidity, which can cause oxidation; dust and debris, which can cause poor contact and wear; contact with chemicals, which can cause corrosion; and solar radiation and extreme temperatures, which can cause drying and degradation of materials, damaging these components and potentially leading to total or partial interruption of the machine's operation. [004] During machine maintenance there may also be exposure to damaging factors, such as the application of water jets and chemicals during cleaning, or oils and lubricants applied to mechanical components, also posing a risk to cables and connectors. State of the art [005] To protect the connectors, protective covers are already known in the state of the art, which are mounted over the connectors, and covers for automotive use or specific for agricultural use can be used. [006] However, existing sheaths end up being damaged as well, needing to be constantly replaced to prevent the wires from being exposed, and suffering permanent damage if they are held in place only by clips, fittings and connecting membranes made of the same material as their main bodies, such as high-density polyethylene, which suffers from drying out and degradation when exposed to environmental factors. [007] Furthermore, the covers are complex to assemble and disassemble, requiring the connector to be completely disconnected and its terminals disconnected in order to be assembled or removed, which considerably increases working time, given the high number of connectors present in agricultural machinery. [008] The already known sheaths also have unfavorable geometries, in which the connector outlets and cables form 90-degree angles that make assembly difficult and cause mechanical interference, requiring the cables to be bent and risk being crushed and damaged during bending, or are completely straight, requiring locking systems to prevent them from sliding along the cables. [009] Document CN216389918 U describes a cover for an automotive wiring harness connector to protect it from impacts from debris such as glass fragments and sand, and from water ingress. However, the cover has a complex system of shock absorbers and cylinders to seal and retain the connectors, is complex to install, does not describe whether it provides chemical resistance, and has a rectilinear geometry. [0010] Document CN219202820 U describes a sealed wiring harness for agricultural machinery, with connectors at both ends protected from debris, corrosion and water ingress by a sheath and a sealing cap. The sheath described, however, has a rectilinear geometry and requires screws to secure the cables. Utility model objectives [0011] Based on the problems in the state of the art pointed out, the objective of the present utility model is to provide a constructive arrangement in a protective cover for electrical connectors of agricultural machinery that has high resistance and can be easily installed and removed. Utility model summary [0012] An object of the present utility model is a cover for connectors of agricultural machinery consisting of two halves divided longitudinally, having an angled shape, so that the cables and the end of the connector form an angle of more than 90 degrees. [0013] Also an object of the present utility model is a cover for connectors of agricultural machinery made of chemically and mechanically resistant material. [0014] Also an object of the present utility model is a cover for connectors of agricultural machinery that can be joined by screws, rivets, or other fastening means with high resistance.
