Description
Technical field
This utility model belongs to test fixation clamp, especially a kind of DC terminal row's test wire fixation clamp.
Background technology
Along with social economy's development, electricity needs is increasing, and electrical network the most constantly expands.Newly-built transformer station and power transformation
Improvement project of standing increases year by year, and this brings great pressure all to relay protection secondary debugging efforts.Duration is tight, task weight,
How to improve work efficiency extremely the most urgent.
In transforming plant protecting debugging efforts, along with the improvement of protection in station, intelligent, needed for automatization, number of signals is all with day
Increasing, it is serious that the verification of direct current signal and test occupy a critically important part for automation of transformation substations test, i.e. this part work
Constrain the duration.Meanwhile, DC terminal is discharged into toward the too small universal test line that cannot insert of jack, the test of direct current signal simultaneously
Journey often there is DC earthing dangerous, so developing a kind of DC terminal that direct current signal can be facilitated to test row's test fixed mount pair
Important effect is had in debugging test.
Summary of the invention
The purpose of this utility model is to overcome current DC terminal row and test wire loose contact situation, is adapted to Multiple Type direct current
Terminal block, while DC earthing situation will not occurring in ensureing experimentation, facilitates the carrying out of signal transmission test.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of DC terminal row's test wire fixation clamp, it is characterised in that: include insulation positioning board, testing terminal, contact, insulation
Jig arm, handle and spring assembly, on insulation positioning board, interval is fixed with two testing terminals, and testing terminal is fixed through insulation
The contact of plate connection insulation positioning board lower end, position, is the most relatively hinged with an insulation jig arm, insulating blanked clamper at the two ends of insulation positioning board
The upper end of arm is all shaped with a upwardly extending handle, handle to clamping both sides, middle part thus drive insulation jig arm to open to both sides；
Between insulation jig arm and insulation positioning board, spring assembly is installed.
And, it is also equipped with a standby insulating end sub-aperture in the middle part of the insulation positioning board between two testing terminals.
And, described contact uses pin contact.
Advantage of the present utility model and good effect be:
1, this utility model volume is little, be convenient for carrying, safe and reliable characteristic, it is not necessary to supernumerary holds walkie-talkie and checks with a distant place
Signal, more ensure that the personal safety of staff and the safe operation of electrical network while improve work efficiency, prevents direct current
The generation of ground connection.
2, this utility model DC terminal row test fixation clamp has easy to use, advantage time saving and energy saving during operation, it is ensured that operation
Personnel can vacate a hands and use walkie-talkie, reduce the feature of debugging test personnel amount.Testing crew is utilizing DC terminal
Row's test fixation clamp is possible not only to conveniently test, and more can guarantee that and will not cause DC earthing because of test, prevents mistaking signal, simultaneously
It is greatly shortened the operating time, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following example are illustrative,
It not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of DC terminal row's test wire fixation clamp, including insulation positioning board 3, testing terminal 4, contact 6, insulation jig arm 7,
Handle 1 and spring assembly 2, on insulation positioning board 3, interval is fixed with two testing terminals 4, and testing terminal is fixed through insulation
The contact 6 of plate connection insulation positioning board lower end, position, the contact of the present embodiment uses pin contact to have telescopic resilience, it is ensured that not
During when doing experiment, contact shrinks in insulating sheath；
Being also equipped with a standby insulating end sub-aperture 5 in the middle part of insulation positioning board between two testing terminals, insulating end sub-aperture can be used
In installing standby testing terminal, increase number of contacts.Require that test clamp test wire jack has enough electric conductivity.
For the ease of being fixed on by insulating blanked clamper on DC terminal row, the most relatively it is hinged with an insulation at the two ends of insulation positioning board 3
Jig arm 7, insulation jig arm lower end is the arcuate structure to center bending, and insulation jig arm goes for the direct current of multiple different in width
Terminal block, convenient reality application；This utility model requires that enough test clamps have enough insulating properties, it is ensured that will not pass through
Test clamp produces DC earthing situation, and test clamp has enough dynamics and intensity, will not take off under test wire depending condition
Fall.
The upper end of insulation jig arm is all shaped with a upwardly extending handle 1, and the handle to clamping both sides, middle part drives insulating blanked clamper arm to two
Side is opened；
Insulation jig arm with insulation positioning board jointed shaft are provided with spring assembly 2 and ensure that insulation jig arm resets, the bullet of the present embodiment
Spring assembly uses conventional torque spring structure.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that:
Without departing from this utility model and spirit and scope of the appended claims, various replacements, to change and modifications be all possible,
Therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
