Description
Technical field
The present invention relates to network transformer field, specifically relate to the diastrophic method of inspection of a kind of network transformer pin.
Background technology
The signal level produced when the chip operation of any CMOS processing procedure is always greater than (the depending on processing procedure and the design requirement of chip) of 0V, and the place that PHY output signal delivers to 100 meters even longer has the loss of very large DC component.If outside netting twine is directly connected with chip, electromagnetic induction and electrostatic are easy to the damage causing chip.Equipment ground method is different besides, power grid environment difference can cause the 0V level of both sides inconsistent, such signal passes to B from A, due to the 0V level of A equipment and the 0V level of B point different, very large electric current may be caused like this to flow to the low equipment of electromotive force from the equipment that electromotive force is high.Network transformer, also known as data pump, network isolation transformer etc., the coil coupling filtering that the differential signal that PHY exports is coupled with differential mode to strengthen signal, and is coupled to other one end of connected with network cable by the conversion of electromagnetic field.So not only make there is no connection physically between netting twine and PHY and change to deliver signal, cut off the DC component in signal, can also transmit data in the equipment of different 0V level, thus, network transformer has very important purposes in daily life.
Common network transformer comprises T1/E1 isolating transformer, ISDN/ADSL interface transformer, T3/E3, SDH, 64KBPS interface transformer; 10/100BASE, 1000BASE-TX network filter; RJ45 integrated transformer etc.It is mainly used in: good digital exchange; SDH/ATM transmission equipment; ISDN, ADSL, VDSL, POE power receiving equipment Integrated Digital Services equipment; FILT optical fiber loop equipment; Ethernet switch etc.Network transformer is provided with a lot to pin, when encapsulating network transformer, the irregular meeting of its pin arrangements brings very large trouble to encapsulation, and affects the use of user.Existing, mostly the detection whether vertically carried out for pin is to utilize artificial visual mode to check, but this mode is also unreliable, the multiple non-vertical situations such as the angle that pin often occurs is crooked, press down or upwarp all are difficult to make accurate judgement by range estimation, are easily passed through to detect by network transformer bending for pin by mistake; And due to pin number more, testing staff's visual fatigue can be caused, cause inefficiency.
Summary of the invention
The object of the present invention is to provide the diastrophic method of inspection of a kind of network transformer pin, solve when detecting whether network transformer pin is bending in prior art and rely on artificial visually examine, exist compared with the problem of big error, realize relying on numerical parameter to bend to network transformer pin the object that situation detects.
The present invention is achieved through the following technical solutions:
The diastrophic method of inspection of a kind of network transformer pin, described method of inspection comprises the following steps: (A), obtain network transformer in zero load, without hindrance extension situation, upper lift power when being carried at the uniform velocity; (B), by the pin of network transformer insert down in the vertical aperture mated with pin size, adopt the speed identical with step (A) at the uniform velocity on carry, obtain upper lift power now; (C) the upper lift power, in comparison step (A) and step (B), judges whether network transformer pin bends.For existing to network transformer pin whether bending detect time rely on artificial visually examine, there is the problem compared with big error, the invention provides the diastrophic method of inspection of a kind of network transformer pin, by to comparison different situations lower network voltage transformer lifting force value, thus judge whether pin occurs bending and deformation.The diastrophic method of inspection of described a kind of network transformer pin, first in zero load, without hindrance extension situation at the uniform velocity on put forward lift power on needed for network transformer and measure and record.Again the pin of network transformer is inserted down in the vertical aperture mated with pin size, for the common network transformer with multiple pin, this vertical aperture is set to all consistent with the network under test transformer lead pin multiple apertures of quantity, spacing, thus is convenient to all pins of network under test voltage transformer all to insert in vertical aperture.Now, adopt with in zero load, without hindrance extension situation at the uniform velocity on carry time identical speed, again at the uniform velocity on carry network transformer, acquisition upper lift power now.Pulling force when above-mentioned twice is carried is compared, when all pins of network transformer are all in completely vertical state, in the ideal case, twice that obtained lifting force value in theory should be equal, consider that inevitable resistance exists, can allow the upper lift force value measured by second time in zero load, without hindrance extension situation at the uniform velocity on fluctuate back and forth near the upper lift force value carried, this kind of situation also thinks that surveyed network transformer pin is in vertical state, does not bend.When the part or all of pin of network transformer to be measured is in case of bending, bending pin and the contact internal walls of described vertical aperture, larger friction drag can be produced when carrying network transformer at the uniform velocity, measured upper lift power is also just obviously greater than zero load, in without hindrance extension situation at the uniform velocity on the upper lift force value carried, and due to the lighter in weight of network transformer own, more can highlight the difference of this value of thrust, thus judge that the pin of this network transformer bends, staff needs to carry out inspection one by one and rectification to its all pin, could encapsulate and dispatch from the factory.
Further, the upper lift power acquisition order in described step (A), step (B) can be put upside down.Method of inspection of the present invention uses the upper lift force value in step (A), step (B) to compare, so when adopting identical at the uniform velocity upward strain speed, the upper lift power acquisition order in step (A), step (B) can be put upside down.
Further, the upper lift power obtained in described step (B), after repetitive measurement, removes peak and minimum, then the aviation value obtained.In described step (B), must vertically on carry network under test voltage transformer, otherwise the upper lift force value obtained easily be subject to vertical aperture hole wall impact and distortion.In order to eliminate the above-mentioned error that may exist, so repeatedly repeat step (B), drawing multiple value of thrust, then removing peak and minimum, remaining value of thrust is averaged, thus increase the accuracy of the upper lift power obtained.
To sum up, the present invention has following beneficial effect:
The diastrophic method of inspection of a kind of network transformer pin provided by the present invention, by obtaining network transformer in zero load, without hindrance extension situation, upper lift power when being carried at the uniform velocity; Again the pin of network transformer is inserted down in the vertical aperture mated with pin size, adopt identical speed at the uniform velocity on carry, obtain upper lift power now, by comparing value of thrust when twice is carried, judge that pin bends situation, thus realize relying on numerical parameter to bend to network transformer pin the object that situation detects.
