Technical Field

The invention belongs to the technical field of airplane accessory structure design, and relates to a button type flow distribution strip root connecting structure.

Background

due to the stable lightning protection effect and the advantage that the radar antenna housing wave-transmitting performance is less affected, the button type lightning protection shunt strip is widely applied to the lightning protection of airplanes, particularly military airplane radar antenna housings. Button type reposition of redundant personnel strip need be connected at the root with cover metal structure such as inner ring, collector ring, bond strap, realizes electric intercommunication, takes to realize reposition of redundant personnel strip and cover body root metal structure's being connected through the flat button head bolt at reposition of redundant personnel strip root usually.

The connection mode of the metal structure at the root of the shunt strip and the root of the cover body through the flat round head bolt is adopted, a root connection hole needs to be manufactured after the shunt strip is installed, and the flat round head bolt is installed. In order to ensure the protection effect of the shunt strip, the gap between the last button of the shunt strip and the nail head of the oblate bolt needs to meet the relevant requirements, the gap cannot be too large, the gap is ensured by the size of the nail head and the position of a connecting hole, the phenomenon that the gap between the button and the connecting hole is small often exists in the actual assembly process, the button is contacted with the button or even interfered, the button structure or the surface coating of the button structure is damaged, and the button is corroded or even falls off in the long-term use process.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the defects in the prior art, the invention provides a button type shunt strip root connecting structure which can meet the requirements of connection and fixation and electric lap joint of a button shunt strip and simultaneously avoid the damage of a connecting bolt to a button nail head in the assembling process.

The technical scheme is as follows: the invention provides a button type shunt strip root connecting structure which comprises a clamp and a connecting fastener, wherein the clamp is arranged on the upper surface of the button type shunt strip root, a through hole is formed in the clamp, and the fastener penetrates through the through hole to fix the clamp, the button type shunt strip root and a cover body on a cover body root metal piece.

the clamp is made of metal materials with good conductivity, such as copper, aluminum, stainless steel and the like, the lower surface of the clamp is provided with a convex groove, the upper end of the clamp is provided with a through hole for a fastener to pass through and be connected, the form of the through hole is determined by the type of the fastener, and the position is determined by the position of a connecting point;

The connecting fastener can be a countersunk head bolt, an oblate head bolt and the like.

When the device is used, the button type shunt strip is arranged on the surface of the cover body, the clamp is arranged above the root part of the button type shunt strip, and the groove below the root part of the button type shunt strip is sleeved on the root part of the shunt strip to fix the shunt strip; the front and back positions of the clamp are adjusted according to the connection point position of the root of the cover body, and the clamp, the cover body and the metal piece at the root of the cover body are connected through the connecting fastener, so that electric lap joint is realized.

The clamp is made of copper materials, so that on one hand, the electric conductivity is excellent, and on the other hand, the high-temperature resistance is strong.

The hoop circumference chamfer is handled, strengthens corrosion resistance, prevents that sharp-pointed edges and corners may cause personnel's equipment's injury.

The fastening screw adopts a straight flat screw, and the straight opening is axially vertical to the shunt strip, so that the lightning erosion of the fastening screw can be reduced.

The beneficial technical effects are as follows: the problem of the connection of button reposition of redundant personnel strip root is solved, can finely tune the connecting piece position, when realizing button reposition of redundant personnel strip connection fixation and electric overlap joint requirement, avoid the damage of connecting bolt to the button pin fin in the assembling process.
