Abstract
The utility model discloses a fast checking tool clamp, which comprises a tabulate bracket body part, wherein a support part is arranged on the bracket body part, a power end A, a power end B and a notch through which a reed is inserted are arranged at one side on the support part; a PTC clamp is arranged at the other side of the support part, and a control drive piece is arranged at the lower end of the support part. Due to adoption of the technical scheme, when the fast checking tool clamp is used, two surfaces of a polymer PTC are clamped by the PTC clamp and are guided out from two poles of the clamp by power wires and connected to two input ends of testing equipment. The fast checking tool clamp is convenient and rapid and has a better technical effect; and the test accuracy is greatly improved.
Description
Technical field
The utility model designs a kind of anchor clamps, especially refers to a kind of frock clamp of checking fast.
Background technology
Landline telephone has that lamprophonia, rate are cheap, environmental protection, conversation are maintained secrecy, kind is abundant, preferential various multiple characteristics.Be fit to all kinds user's daily use, application is flexible, convenient, and business function is complete.It remains one of modern main means of communication.
Main frame (MDF) is an important composition part in the fixed telephone network, and its outside line side connects copper core double cut line local telephone communication cable, and the interior lines side connects the telecommunications exchange or connects the subscriber's line circuit of people's equipment, can carry out the wire size distribution through wire jumper and continue.And have the superpotential over-current protection, accuse for function and test port.
The capacity of main frame (MDF), big can be greatly to the machine room of more than 10 ten thousand loop lines, little can little outdoor cabinet to 200 loop lines, the installation site from the city office, to county telephone central office, to the rural area suboffice etc., it is very extensive to distribute.Because the overhead system of China is many, particularly the rural area is intricate; If aging circuit, or fortuitous event such as thunderbolt are in case touch external cable; Just might burn out main frame (MDF) and calculator room equipment, thereby cause machine room to catch fire, cause disaster.
Main frame (MDF) is made up of support body, safety wire connection row, test line bank, Security Unit, warning system five major parts; Wherein Security Unit is the core part in the main frame (MDF), and the high molecular PTC of forming in this unit is the core devices that in main frame (MDF), plays overcurrent protection.
When detecting high molecular actuation time and non-operating current, be originally to place it on the copper coin that another side is held test pencil with hand and pushed down and detect.The heat radiation that its defective one is a copper coin is very fast, the measurement data out of true, and the 2nd, each amount detection is more, takes test pencil to pin another side with hand for a long time, and is not only time-consuming but also hard.
The utility model content
The utility model provides a kind of frock clamp of checking fast to existing technical disadvantages, and it has the high technological merit of test accuracy.
It is following that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of anchor clamps of the instruments of inspection fast; Comprise flat rack body portion, be provided with a seat part above the said rack body portion, a side is provided with power supply A end, power supply B end and reed and inserts notch on the seat part; Opposite side is provided with the PTC anchor clamps, is provided with the control dialing part in the lower end of seat part.
Further, preferred construction is to electrically contact together between the two poles of the earth of said power supply A end, power supply B end and PCT anchor clamps.
Further, preferred construction is, locates to be provided with bolted fastener around the said rack body portion.
The utility model has been taked after the technique scheme; When in use, the PTC clamp clamps is used on the two sides of high molecular PTC, drawn two input ends that are connected to testing apparatus with power lead from the two poles of the earth of anchor clamps then; Both convenient; Quick again, test accurately improves greatly, has better technical effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is the synoptic diagram that the utility model is checked frock clamp fast.
Embodiment
Come the utility model is carried out detailed description below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the synoptic diagram that the utility model is checked frock clamp fast.
As shown in Figure 1, the said frock clamp of checking fast is primarily aimed in the prior art when detecting high molecular actuation time and non-operating current, is originally to place it on the copper coin, and another side is held test pencil with hand and pushed down and detect.The heat radiation that its defective one is a copper coin is very fast, and the coarse shortcoming of measurement data proposes.
Like Fig. 1; The said anchor clamps of the instruments of inspection fast; Comprise flat rack body portion 1, be provided with a seat part above the said rack body portion 1, the one of which side is provided with power supply A end 2, power supply B end 3 and reed and inserts notch 4; Opposite side is provided with PTC anchor clamps 5, is provided with control dialing part 7 in the lower end of seat part.
Wherein, electrically contact together between the two poles of the earth of said power supply A end 2, power supply B end 3 and PCT anchor clamps 5.In addition, around said rack body portion, locate to be provided with bolted fastener 6.
The use-pattern of the utility model is as shown below:
1, two metal sheets being inserted reed inserts among the notch;
2, two wiring on the anchor clamps are connected on the connection terminal of detecting instrument;
3, open power switch device, mix up the parameter knob that will detect;
4, high molecular PTC is put into anchor clamps;
5, press the testing tool button, the numerical value that show on the instrument this moment is exactly the test value of tested high molecular PTC.
And, detecting instrument and anchor clamps are lain on the work top, detect by above-mentioned the 5th requirement; After having surveyed one, only need the measured piece high molecular PTC is taken off, change another one and get on; Again click the detection button; The numerical value that shows on the instrument is exactly measured value, so back and forth, can measure a collection of product easily and efficiently.
Through on-the-spot test, and to contrast originally, same batch test duration has shortened nearly 50% than originally.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
