Abstract
The utility model relates to the technical field of isolation amplifier casings, and specifically relates to a metal casing for an isolation amplifier. The metal casing comprises a metal shielding box. The upper surface of the metal shielding box is provided with a rectangular hole, and a metal cover plate is arranged on the rectangular hole. The metal casing further comprises metal lead wires which are arranged on two sides of the lower surface of the metal shielding box. The metal lead wires pass through the lower surface of the metal shielding box and protrude into the metal shielding box. The periphery of the rectangular hole is provided with grooves, and the periphery of the metal cover is plugged into the grooves on the periphery of the rectangular hole and connected with the metal shielding box. According to the utility model, the shielding box is provided with the rectangular hole, and connected with the metal cover by the rectangular hole in a plug-in manner, so that the rectangular hole facilitates the put-in and replacement of a substrate, and the defects that the conventional connection structure of the casing cover and the casing is achieved by welding and can be used for only once, and the material is greatly wasted are overcome. The metal casing is simple in structure and convenient in use.
Description
Technical field
The utility model relates to the technical field of isolated amplifier shell, especially a kind of isolated amplifier metal shell.
Background technology
Use the shell of the isolated amplifier on rocket, air equipment, mainly for isolation voltage, metal cover board is mainly to suppress to ridicule sound release and invade, but the structure of the isolated amplifier metal shell using is at present divided into two parts, be respectively metal shell and cover plate, cover plate and shell adopt welding, and this shell can only use once, have wasted greatly material when having reduced the utilization rate of shell.
Utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of isolated amplifier metal shell.
The utility model solves the technical scheme that its technical problem adopts: a kind of isolated amplifier metal shell, comprise metal shielding box, described metal shielding box upper surface is provided with rectangular opening, described rectangular opening is provided with metal cover board, also comprise metal lead wire, described metal lead wire is arranged on metal shielding box lower surface both sides, and described metal lead wire passes metal shielding box lower surface and stretches in metal shielding box.
According to another embodiment of the present utility model, further comprise that described rectangular opening surrounding is provided with groove, in the groove of described metal cover board surrounding by insertion rectangular opening surrounding, be connected with metal shielding box.
The beneficial effects of the utility model are, on shielding box, have rectangular opening, and on rectangular opening, adopt plug-in type mode connection metal cover plate, rectangular opening facilitates putting into and changing of substrate, solve present shell lid and shell and be the connected mode of welding and can only use once, greatly waste the drawback of material and simple in structure, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
1. metal shielding boxes in figure, 2. rectangular opening, 3. metal cover board, 4. metal lead wire, 5. groove.
Embodiment
As depicted in figs. 1 and 2, a kind of isolated amplifier metal shell, comprise metal shielding box 1, metal shielding box 1 upper surface is provided with rectangular opening 2, rectangular opening 2 is provided with metal cover board 3, also comprise metal lead wire 4, metal lead wire 4 is arranged on metal shielding box 1 lower surface both sides, and described metal lead wire 4 passes metal shielding box 1 lower surface and stretches in metal shielding box 1.Wherein rectangular opening 2 surroundings are provided with groove 5, in the groove 5 of metal cover board 3 surroundings by insertion rectangular opening 2 surroundings, are connected with metal shielding box 1.
The utility model in use, first in metal shielding box 1, put into substrate, then metal cover board 3 is inserted in the groove 5 of rectangular opening 2 surroundings and built, as changed substrate, open metal cover board 3, the electric current of shielding flows out by metal lead wire 4.
The utility model has rectangular opening 2 on metal shielding box 1, and on rectangular opening 2, adopt plug-in type mode connection metal cover plate 3, rectangular opening 2 facilitates putting into and changing of substrate, solve present shell lid and shell and be the connected mode of welding and can only use once, greatly waste the drawback of material and simple in structure, easy to use.
