There are two guiding isolation boards 12, the two guiding isolation boards 12 are arranged in a one-to-one correspondence with two sheet metals 4, and the guiding is isolated
The pilot hole of perforation is provided in plate 12 along the extending direction of its corresponding sheet metal 4, it is right that the sheet metal 4 is threaded through its
In the pilot hole for the guiding isolation board 12 answered.
It is understood that two guiding isolation boards 12 are arranged in the upper housing 1 of the present embodiment signal supervisory instrument, and every
The extending direction of sheet metal 4 is provided with pilot hole respectively in a guiding isolation board 12, such two metal sheets 4 can directly be distinguished
It is threaded through in the pilot hole of a guiding isolation board 12, since two guiding isolation boards 12 are independent from each other, is led so being threaded through
Two metal sheets 4 into the pilot hole of isolation board 12 can naturally also be isolated.Setting two in the upper housing 1 of the present embodiment detection device
Root guiding isolation board 12 avoids the extension in upper housing 1 of two metal sheets 4 and contacts to produce due to mobile or dislocation
The generation of raw short-circuit conditions.
In order to facilitate the setting in telephone connection hole and the patching operations of telephone wire, the length of the guiding isolation board 12 is small
It is located at the length in the upper housing 1 in its corresponding sheet metal 4, and the two guiding isolation board 12 is each attached to upper casing
The same side of body 1, and the corresponding sheet metal 4 of pilot hole of each guiding isolation board 12 is solid in the guiding isolation board 12
Determine the connection setting of sheet metal socket 13 on the shell of side.
Correspondingly, as shown in figure 4, the telephone line string holes 14 setting is isolated in the upper housing 1 away from the guiding
On the side of plate 12.In this way specifically carry out telephone wire wiring when, can directly by telephone wire by telephone line string holes 14 with
The exposed sheet metal 4 in upper housing 1 and outside guiding isolation board 12 connects.
In order to guarantee that the isolation of the exposed two metal sheets 4 in guiding 12 outer portion of isolation board is fixed, the inspection of the present embodiment signal
It surveys in the upper housing 1 of device and is additionally provided with sheet metal fixed plate 5.The setting of sheet metal fixed plate 5 is separate in the upper housing 1
Inside the side of guiding 12 affixed side of isolation board, and corresponding two sheet metals 4 are set respectively in the sheet metal fixed plate 5
It is equipped with guiding isolation channel, the sheet metal 4 is fixed in the guiding isolation channel far from one end of the guiding isolation board 12.
And corresponded in the sheet metal fixed plate 5 the telephone line string holes 14 be provided with the connection telephone line string holes 14 with it is upper
Recess hole inside shell 1.
It is understood that the present embodiment signal supervisory instrument, passes through the group of sheet metal fixed plate 5 and guiding isolation board 12
It closes and uses, the generation of short-circuit conditions can be occurred due to dislocation by effectively avoiding two metal sheets 4 in 1 inner part of upper housing, together
When can be convenient again telephone wire is connect by the recess hole on telephone line hole and sheet metal fixed plate 5 with two metal sheets 4.
As shown in the figures 1 and 2, the indicator light wiring hole 11 includes two be arranged on the upper face of the upper housing 1,
Two indicator light wiring holes 11 are able to be connected to a piece of copper sheet.Accordingly as shown in figure 3, every piece of guiding isolation board 12
It is respectively set and respectively corresponds there are two column type through-hole as an indicator light wiring hole 11.
And the indicator light wiring hole 11 of the present embodiment signal supervisory instrument is preferably provided at close to telephone line string holes 14
Side.
As a preferred embodiment, the upper housing 1 is structure as a whole with the two guiding isolation boards 12；The guiding
Isolation board 12 is structure as a whole with the column type through-hole being correspondingly arranged thereon.
The present embodiment signal supervisory instrument, when specifically used, by the copper sheet at 1 both ends of the upper housing end with VDF frame respectively
Mouth connection, connects phone by access telephone wire；Telephone current signal, signal isolator can be observed by being inserted into indicator light
3 realize signal isolation.It should be noted that the present embodiment signal supervisory instrument when specifically used, is connected telephony feature, is seen
Examining semiotic function and signal isolation function can according to need and carry out selecting single or be applied in combination, that is, can only exist
