Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is further described:

[0016] figure 2 , image 3 , Figure 4 As shown, a combined lightning protection shunt strip includes a button-type lightning protection shunt strip 2 and an electrical lap joint 3; the electrical lap joint 3 forms a groove, and the lightning protection shunt strip 2 is inserted into the recess In the groove, it is fixedly connected with the electrical lap joint 3 to form a whole. The distance between the groove entrance end surface and the first button of the button-type lightning protection shunt strip is not more than 0.5mm, and the gap between the groove and the lightning protection shunt strip 2 It should be within the range of 0.2 mm to 0.5 mm. The depth of the lightning protection shunt strip 2 inserted into the groove is not less than 9 mm. 1 surface. The material of the electrical lap joint 3 is made of aluminum or copper; the electrical lap joint 3 and the lightn...

Abstract

The present invention belongs to the technical field of structure design, especially relates to a combined anti-lightning shunt bar. The combined anti-lightning shunt bar comprises a button anti-lightning shunt bar (2) and an electric lapping joint (3). One end of the button anti-lightning shunt bar and the electric lapping joint are fixedly connected through an adhesive to form one body, and at the same time, the distance between the end face of the inlet of the groove of the electric lapping joint and a first button of the button anti-lightning shunt bar is not larger than 0.5mm, so that ina required range, the anti-lightning effect of the button anti-lightning shunt bar is greatly improved, and the combined anti-lightning shunt bar can ensure that a radome is smoothly installed on an aircraft, simplifies the craft process of installation of the button anti-lightning shunt bar and saves the assembling time.

Description

technical field [0001] The invention belongs to the technical field of structural design, and in particular relates to a combined lightning protection shunt strip. Background technique [0002] In the existing technology, the lightning protection shunt bar and the grounding sheet are usually connected and fixed by electric lap screws. In this way, during assembly, it is easy to cause the distance between the grounding piece and the button of the lightning protection shunt bar to be out of tolerance. Unpredictable impact on lightning protection. In addition, if the position of the electrical lap screw is improperly selected, it is very easy to interfere with the aircraft structure, causing problems such as the repair of the radome. Contents of the invention [0003] Purpose of the present invention: In the present invention, the lightning protection shunt strip and the grounding plate structure are first fixed, and then the shunt strip is bonded and other processes are pe...
