Description

Technical Field

[0001] The utility model belongs to the technical field of lightning protection and guidance of airborne electronic products, and in particular relates to a lightning protection and guidance device. Background Art

[0002] A jettisonable airborne electronic device is installed on the outer surface of the aircraft. Since the shell material of the device is a wave-transmitting composite material, which is itself insulated, the material itself cannot guide the current to the ground wire when it encounters a lightning strike. There may be a risk of current accumulation after the lightning strike, causing damage. Therefore, it is necessary to connect the jettisonable airborne electronic device to the airborne ground wire.

[0003] However, if it is directly connected to the onboard ground wire, the jettisonable airborne electronic equipment will not be able to separate in an emergency. Utility Model Content

[0032] The lightning protection guide device provided by the utility model is explained below in conjunction with the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides a lightning protection guide device, comprising: an airborne electronic device 1, a mounting frame component 2; wherein,

[0034] The airborne electronic device 1 comprises: a cover plate 11, a base 12, a conductive mesh 13 and electronic components, wherein the electronic components are arranged in a housing formed by the cover plate 11 and the base 12, and a conductive ejector pin seat 121 is arranged on the base 12;

[0035] The mounting frame component 2 is fixedly arranged on the aircraft, and a conductive top pin 21 is arranged on the mounting frame component 2, and the conductive top pin 21 is connected and conducted with a grounding wire component 22 of the aircraft;

[0036] The onboard electronic device 1 is arranged in the mounting frame component 2, and the conductive ejector pin 21 is inserted into the conductive ejector pin seat 121;

[0037] The conductive mesh 13 is laid on the cover plate 11 and the base 12, and conducts the outer surface of the cover plate 11 and the conductive top pin seat 121, so as to realize lightning protection and guide the lightning to the grounding wire.

[0038] The lightning protection guide device provided by the utility model utilizes the original airborne electronic equipment and the mounting frame components of the original airborne electronic equipment. It only needs to modify the top pin on the original mounting frame component to a conductive top pin, and connect the grounding wire, and then arrange the conductive net and the conductive top pin seat on the outer casing of the airborne electronic equipment, so as to retain the original airborne electronic equipment's launching structure and realize the lightning protection of the launched electronic equipment at the same time.

[0039] Optionally, the cover plate 11 is provided with a through hole;

[0040] The outer surface and the inner surface of the cover plate 11 are both paved with a conductive mesh 13, and are electrically connected via a conductive electrode 111 disposed in the through hole;

[0041] The conductive mesh 13 on the inner surface of the cover plate 11 extends to the contact portion between the cover plate 11 and the base 12 . The conductive mesh 13 is also laid on the contact portion between the base 12 and the cover plate 11 and extends to the conductive ejector pin seat 121 .

[0042] Optionally, the through hole is located in the middle of the cover plate 11 .

[0043] Optionally, the conductive mesh 13 on the outer surface of the cover plate 11 is in the shape of a long strip passing through the through hole.

[0044] Optionally, there are multiple conductive ejector pin seats 121 , and a conductive mesh 13 is laid on each conductive ejector pin seat 121 .

[0045] Optionally, the conductive mesh 13 is a conductive copper mesh, and the conductive electrode 111 is a conductive copper electrode.

[0046] like Figure 1 The airborne electronic equipment is divided into a cover plate and a base. The base is provided with a push pin seat for non-rigid connection. The mounting frame component is provided with a push pin at the corresponding position of the push pin seat, which can realize the fixation of the equipment and complete jettisoning and separation in emergency situations.

[0047] When the airborne electronic equipment is struck by lightning, the lightning current is transferred from the conductive copper mesh on the outer surface of the cover plate to the inner surface of the cover plate through the conductive copper electrode, and then transferred to the conductive top pin seat of the base through the contact position between the cover plate and the base. The contact between the conductive top pin on the mounting frame component and the conductive top pin seat can transfer the current to the grounding wire component behind the conductive top pin to achieve grounding, thereby protecting the airborne electronic equipment.

[0048] like Figure 3 and Figure 4 As shown in the figure, the ejector pin seat is installed on the rear end face of the equipment, and the ejector pin is installed on the rear end face of the mounting frame, and cooperates with the ejector pin seat. Both the ejector pin and the ejector pin seat are made of metal materials, and the two cooperate through the conical surface. When the equipment is working on the machine, the ejector pin and the ejector pin seat cooperate closely to fix the equipment. In an emergency, the front end of the equipment is lifted up by the power equipment, and the rear end is flipped around the ejector pin to achieve the ejection action. Until it is completely separated.

[0049] The conductive copper mesh of the equipment extends to the top pin seat and contacts the top pin. When a lightning strike occurs, the current can be guided to the mounting frame through the top pin seat.

[0050] Since the equipment needs to be completely separated from the mounting frame in an emergency, if the grounding wire of the equipment is directly connected to the mounting frame or the machine body, a device for cutting off the grounding wire should be added when the equipment is separated. By using the structure of the top pin and the top pin seat, the connection between the equipment and the mounting frame can be achieved, and the reliable separation in an emergency can be achieved, and the lightning current can be guided to the machine body without adding additional devices or parts.
