Drawings
FIG. 1 is a structural cross-sectional view of the present invention;
wherein: 1. a bonding sheet, 2, a button type lightning protection shunt strip, 3, a button, 4 and a base strip.
Detailed Description
The following detailed description of the embodiments of the present invention, such as the shapes, configurations, mutual positions and connection relationships of the components, the functions and operating principles of the components, the manufacturing processes and the operation and use methods thereof, will be further described in detail with reference to the accompanying drawings, so as to help those skilled in the art to more completely, accurately and deeply understand the concept and technical solutions of the present invention:
as shown in fig. 1, a lightning protection shunt bar connection structure which easily ensures a butt joint gap comprises a bond strap 1 and a button type lightning protection shunt bar 2;
the bonding sheet 1 is long and is used for conducting lightning current, two ends of the bonding sheet are arc end faces or rectangular end faces, the bonding sheet 1 has a certain thickness, enough mechanical strength is kept conveniently during installation, and the bonding sheet is not easy to damage in the installation process; the button strip 1 is made of metal copper or iron, a layer of anti-corrosion coating is coated on the surface of the button strip after polishing, an opening is formed in the joint of the button strip 1 and the electric overlapping end of the button lightning protection shunt strip 2 and is a rectangular opening or an arc opening, the opening is formed by machining, the width of the opening is matched with the diameter of the button 3 and needs to be slightly larger than the diameter of the button 3, the width of the opening is D-1.1D, D is the diameter of the button 3 and can ensure that the first button 3 on the base strip 4 can completely enter the opening, the preferred scheme is that the opening width is designed to be D, the first button 3 on the base strip 4 can completely enter the opening, the button 3 can be ensured to be in complete contact with the button strip 1, and the opening width precision can ensure the distance between the button strip 2 and the last lightning, so that a passage is formed.
The depth of the opening of the bonding sheet 1 is D, so that the opening forms a square groove, the first button 3 on the base strip 4 can be just placed, the space is not wasted, good contact can be ensured, and the opening penetrates through the top and the bottom of the bonding sheet 1.
In fig. 1, the lightning protection reposition of redundant personnel strip 2 of button formula includes base strip 4 and evenly arranges button 3 on base strip 4, all buttons 3 are located same straight line, the distance between per two adjacent buttons 3 is the same, button 3 is fixed on base strip 4 through riveted mode, the riveting mode belongs to the quiet cooperation and connects, firm in connection is difficult not hard up, before connecting button 3, set up the mounting hole on base strip 4 now, then scribble the one deck antirust agent on button 3 surface, install button 3 in the mounting hole again, button 3 is made by metal copper, metal copper electric conductive property is good, and good mechanical strength has, base strip 4 is made by glass steel, or also can select for use other have insulating properties good, fire prevention high temperature resistant combined material.
When the lightning protection device is installed, the button type lightning protection shunt strip 2 is firstly bonded at the corresponding position of the outer surface of the radome through the adhesive, then the bonding sheet 1 is installed, and the opening end of the bonding sheet 1 is required to be aligned with the corresponding button 3 of the button type lightning protection shunt strip 2 when the lightning protection device is installed. The first button 3 of the button type lightning protection shunt strip 2 close to the opening end of the bonding sheet 1 enters the opening in the bonding sheet 1, and the depth of the button 3 entering the opening in the bonding sheet 1 is at least 0.5D-D, preferably D.
