Description
Technical field
The utility model belongs to the testing tool technical field of communication cabinet, more particularly to a kind of rack direct current reserves line
Test fixture.
Background technology
In the production detection of communication cabinet, the direct current in rack reserves line and is usually whether all universal meters measure voltage
It is qualified, but operative employee in the case of careless can not accurate judgement direct current reserve line both positive and negative polarity it is whether reversed, itself survey
- 48 volts during the voltage of amount, in voltage in the case of reversed 48 volts, and the test pencil of universal meter also connects to the both positive and negative polarity for reserving line
Wrong possibility, can so influence testing efficiency, damage universal meter sometimes, cause cost to waste.
Utility model content
The purpose of the utility model embodiment is the test fixture for providing a kind of reserved line of rack direct current, can be quick
Complete the test to reserving line.
What the utility model embodiment was realized in：
A kind of rack direct current reserves the test fixture of line, including shell, buzzer, light emitting diode, crocodile clip, frock
Lid and cable, crocodile clip are electrically connected by cable with buzzer and light emitting diode, and buzzer and light emitting diode are arranged side by side
Covered in frock, shell is fixedly connected to form square with frock lid, and the top surface of shell offers exposed buzzer and luminous two
The opening of pole pipe, the side of shell offer the opening passed through for cable.
The utility model embodiment in frock by setting crocodile clip, buzzer and light emitting diode, when crocodile clamping connection
To rack reserve line it is correct when, buzzer can alarm while lumination of light emitting diode, intuitive judgment reserve line whether correctly reserve,
The efficiency of test is improved, improves product quality, ensures personnel's safe operation.
Brief description of the drawings
Fig. 1 is the overall structure figure of test fixture of the present utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Specific implementation of the present utility model is described in detail below in conjunction with specific embodiment：
As shown in figure 1, a kind of rack direct current reserves the test fixture of line, including shell 1, buzzer 2, light emitting diode
3rd, crocodile clip 4, frock lid 5 and cable 6, crocodile clip 4 are electrically connected by cable 6 with buzzer 2 and light emitting diode 3, buzzer 2
It is disposed side by side on light emitting diode 3 on frock lid 5, shell 1 is fixedly connected to form square, the top surface of shell 1 with frock lid 5
The opening of exposed buzzer 2 and light emitting diode 3 is offered, the side of shell 1 offers the opening passed through for cable 6.It is luminous
Diode 3 can be two, this test fixture small volume, easy to carry, when rack is tested, can make as conventional tool
With improving the efficiency of test, flexibly used in producing line.
The process that rack reserves line test is as follows：
A., the crocodile clip of frock electrode line cable is clamped to OT terminal (or the cold pressing end that line electrode line cable is reserved in rack
Son), the crocodile clip of frock negative line cable clamps the OT terminal (or cold end terminal) that line negative line cable is reserved in rack, cable
The contactless short-circuit risks of both positive and negative polarity are checked after clipping；
B. open direct current and reserve and switched corresponding to line, now the buzzer in frock sends sound, bright light diode
Indicator lamp green light Chang Liang；
C. after passed examination, close direct current and reserve switch corresponding to line, remove the crocodile clip on the reserved line of direct current, inspection
Look into and whether there is scratch on OT terminal (or cold end terminal).
In embodiment of the present utility model, frock, the color of frock cable are formulated according to the color that line is reserved in product
The color cable of frock both positive and negative polarity need to be docked according to the color of reserved line, can be prevented just with the solid colour of reserved line
Negative pole cable wrong, the other end of frock is using buzzer, light emitting diode, resistance, by the sound of buzzer, bright after energization
Lamp diode indicator lamp come judge direct current reserve line whether energization.The alternative reserved line of universal meter detection of this frock whether there is
Voltage, the detectable reserved line both positive and negative polarity wrong of direct current is reversed, ensures that product ensures that electrical property is good in use.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, it is all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
