Abstract
An electrophysiological faraday box includes a main body, a work board, and a foldable door. The main body is able to provide an electromagnetically isolated space at the time when it is grounded by a bonding wire. The work board is mounted in the space of the main body and is an insulator. The foldable door is fastened to one side of the main body such that the foldable door can be opened partially or completely to enable a person to gain access to the work board. The foldable door is formed of a plurality of door units which are formed of metal screens electrically interconnected by a bonding wire. The side walls, the top, and the bottom of the main body are formed of framed metal screens electrically interconnected by a bonding wire.
Description
FIELD OF THE INVENTION
The present invention relates generally to an electrophysiological faraday box for use in an animal electrophysiological experiment, and more particularly to an electrophysiological faraday box having an electromagnetic isolation main body, an electromagnetic isolation folding door, and an electrically insulated work table.
BACKGROUND OF THE INVENTION
In light of an animal subject being susceptible to interference by the electromagnetic wave, the experimental result of an animal electrophysiological experiment is often compromised. It is therefore imperative that such experiment must be carried out in an environment which is electromagnetic isolation to ensure that the animal subject is immune from the electromagnetic interference.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide an electrophysiological faraday box which provides a space electromagnetically shielded.
It is another objective of the present invention to provide an electrophysiological faraday box which has an adjustable work space.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by the electrophysiological faraday box comprising:
an upright electromagnetic isolation main body which is provided with a bonding wire adapted to be grounded;
an electrically non-conductive work board mounted horizontally in said main body; and
a foldable door fastened to one side of said main body such that said foldable door can be opened or closed partially or completely;
wherein said main body is provided in a top, a bottom, a left side, a right side, and a rear side with a metal frame and a metal screen held in said metal frame, wherein said metal screens of said main body are electrically interconnected by a bonding wire;
wherein said foldable door is formed of a plurality of door units, with each being formed of a metal frame and a metal screen held in said frame, wherein said metal screens of said door units of said foldable door are electrically interconnected by a bonding wire.
Preferably, said work board is mounted on the bottom of said main body.
Preferably, the electrophysiological faraday box of the present invention further comprises a base which is located under said main body for keeping articles.
The foregoing objectives, features, and functions of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
shows a perspective view of an electrophysiological faraday box of the preferred embodiment of the present invention.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
As shown in
FIG. 1
, the electrophysiological faraday box constructed according to one of the preferred embodiments of the present invention comprises an upright electromagnetic isolation main body
10
, a foldable door
20
, an electrically non-conductive horizontal work board
30
, and a bonding wire
40
adapted to be connected with the ground.
With the exception of the foldable door
20
, the top
15
, the bottom (not shown in the drawing), and three side walls
12
of the main body
10
are made of a frame of aluminum alloy and a copper screen
17
which is held in the frame and is electroplated with chromium. The screens
17
of the side walls
12
, the top
15
, and the bottom are electrically interconnected with a bonding wire
18
fastened therewith by soldering. The screen
17
of one side wall is electrically connected with the bonding wire
40
which is connected with the ground.
The foldable door
20
is fastened to the fourth side of the main body
10
and is formed of three door units
21
which are hinged together. Each of the door units
21
is formed of a frame
24
of aluminum alloy and a copper screen
25
held in the frame
24
and electroplated with chromium. The screens
25
of the three screen units
21
are electrically interconnected by a bonding wire
22
. The third door unit
29
of the foldable door
20
is hinged with the main body
10
. A bonding wire
23
is provided to electrically connect the main body
10
and the foldable door
20
. The second and third door units
28
and
29
are provided with a latch
26
for locking with the main body
10
, so that the foldable door
20
can be opened or closed completely or only with the first door unit
27
being used.
The work board
30
is horizontally mounted on the bottom of and inside the main body
10
. Further, an additional electrically non-conductive board
35
is horizontally mounted inside the main body
10
and above the work board
30
at a predetermined distance.
The present invention further comprises a base
50
which is located under the bottom of the main body
10
and is provided with a plurality of drawers and the like for keeping articles.
The experiment of the animal subject is done on the work board
30
without the interference of the electromagnetic wave. Depending on the requirements of the experiment, the foldable door
20
can be partially or fully opened, thanks to the first door unit
27
, the second door unit
28
, and the third door unit
29
.
Claims
