Abstract
The utility model relates to a limit switch for aircraft radome test contains insulating strip, fixed metal sheet, metal shrapnel, shell fragment metal connecting strip. Metal shrapnel passes through the connecting piece to be fixed on the insulated strip, and shell fragment metal connecting strip is through many metal shrapnel connection of welding mode for all metal shrapnels switch on, and shell fragment side binding post is compressed tightly on metal shrapnel through the screw, and under the normal condition, radome and other parts do not take place the contact, if radome touches, at first touch metal shrapnel, press metal shrapnel to fixed metal sheet on, will communicate the circuit, control stop action. The embodiment of the utility model provides a can prevent effectively that aircraft radome from causing the damage in the test process, guarantee radome and receiving antenna's safety.
Description
Technical Field
The utility model relates to a limit switch for test of aircraft radome.
Background
Aircraft radomes require electrical thickness testing before leaving the factory. In the testing process, the airplane radome is precisely positioned under the drive of special testing equipment. In order to prevent the collision between the radome and the receiving antenna caused by the problem of the program of the radome special equipment in the using process, a special limit switch is designed around the receiving antenna.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem do: the radome is prevented from being damaged due to hard collision between the radome and the receiving antenna.
The utility model discloses technical scheme as follows:
the utility model provides a limit switch for aircraft radome test, contain receiving antenna 1, shell fragment side binding post 2, mount pad 6 under the receiving antenna, fixed metal board side binding post 8, metal bracket 9, insulating pad 10, gland 11 on the receiving antenna, radome 12, a serial communication port, still contain insulating strip 3, fixed metal board 4, 5 shell fragment metal connecting strips of metal shell fragment 7, fixed metal board 4 structure passes through the connecting piece to be fixed on insulating pad 10, insulating strip 3 passes through the connecting piece to be fixed on fixed metal board 4, metal shell fragment 5 passes through the connecting piece to be fixed on insulating strip 3, make the one end of metal shell fragment 5 align with the border of receiving antenna 1, 5 end connection of many metal shell fragments are passed through welding mode to shell fragment metal connecting strip 7, shell fragment side binding post 2 compresses tightly on metal shell fragment 5 through the connecting piece.
The beneficial effects of adopting the above scheme are as follows: the damage of the airplane radome in the test process is effectively prevented, and the safety of the radome and the receiving antenna is ensured.

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
FIG. 1 is a schematic view of a limit switch and peripheral structure connection for aircraft radome testing
As shown in fig. 1, a connection mode of a limit switch and a peripheral structure for an aircraft radome test is shown, and the connection mode can meet the effect of protecting a receiving antenna and a radome.
The method comprises the following steps: receiving antenna 1, shell fragment side binding post 2, insulator strip 3, fixed metal sheet 4, metal shrapnel 5, mount pad 6 under the receiving antenna, shell fragment metal connecting strip 7, fixed metal sheet side binding post 8, metal bracket 9, insulating pad 10, gland 11 on the receiving antenna, radome 12.
The receiving antenna lower mounting seat 6 is fixed on the metal bracket 9 through a screw, the receiving antenna upper gland 11 is connected with the receiving antenna lower mounting seat 6 through a screw, and the receiving antenna 1 is fixed between the receiving antenna lower mounting seat and the receiving antenna upper gland;
the insulating pad 10 is fixed on the lower mounting seat 6 of the receiving antenna and the upper gland 11 of the receiving antenna through screws;
the fixed metal plate 4 structure is fixed on the insulating pad 10 through screws;
the fixed-metal-plate-side connection terminal 8 is pressed against the fixed metal plate 4 by a screw;
the insulating strip 3 is fixed on the fixed metal plate 4 through a screw;
the metal elastic sheets 5 are fixed on the insulating strip 3 through screws, so that one ends of the metal elastic sheets 5 are aligned with the edge of the receiving antenna 1;
the elastic sheet metal connecting bars 7 connect the tails of the metal elastic sheets 5 in a soldering mode, so that all the metal elastic sheets 5 are conducted;
the terminal 2 at the side of the elastic sheet is pressed on the metal elastic sheet 5 through a screw;
FIG. 2 is a schematic diagram of the position relationship between a limit switch and the outer wall of a radome for testing the aircraft radome
As shown in fig. 2, a spatial position relationship between a limit switch and a radome for an aircraft radome test is shown, so that the whole limit switch can be conveniently explained and understood.
Under normal conditions, the radome 12 does not contact with other parts, if the radome 12 touches, touch metal shrapnel 5 at first, press metal shrapnel 5 to fixed metal sheet 4 on, will communicate the circuit, control stop action.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
