Description
Technical field
The present invention relates to the electrostatic discharge testing technology, particularly a kind of electro-static discharge test device, system and method.
Background technology
When two different objects were in contact with one another, an object was positively charged owing to lose electronics, and another object is electronegative owing to obtain electronics.When two objects separate, if on the object with electric charge be not neutralized, thereby electric charge will make static on the object band in accumulation on the object.In network communication field; Be easy to produce static on the various device; For avoiding static discharge to make equipment produce electrostatic damage, adopt common static discharge standard method of test (the electrostatic discharge testing method of for example stipulating in the national standard) that equipment is carried out electrostatic discharge testing usually.But the static discharge that the electrostatic discharge testing method in the national standard has been produced when only having considered to simulate the metal chassis of human body contact arrangement is to the harm of equipment.Common employing can produce the static gun (or claiming electrostatic discharge simulation device) of the high-pressure electrostatic of conformance with standard definition according to user's requirement equipment is carried out static discharge.For example; Hole wall, slit and the non-conducting portion that can adopt static gun to be directed against metal chassis are carried out atmospherical discharges; Perhaps adopt static gun that the metallic conduction of metal chassis is partly carried out contact discharge, perhaps adopt static gun that horizontal coupling plate and vertical coupled plate are carried out contact discharge.After employing is carried out static discharge by static gun to equipment, if equipment work thinks then that normally the antistatic test of equipment passes through.But the test result that existing various method of testing draws all is a static that the simulation human body produces when the metal chassis of equipment is carried out static discharge; The antistatic effect of equipment that is to say that existing method of testing only can draw the test result of device external being carried out static discharge.
But in the practical application, a lot of electrostatic damages are that static is introduced in the inside of equipment when occurring in slave unit plug cable through cable.The passage of static access arrangement is not merely the signal wire that network over the ground also comprises cable in this case; Static on the signal wire of cable must be sought a shortest path over the ground and release; If the equipment inner structure design is improper; Static is probably released through chip, thereby causes the damage of chip.Port with equipment is an example, and a kind of situation is that the electric charge on the cable can enter into port inside through cable, thereby equipment is caused electrostatic hazard when being inserted into the cable of having assembled a certain amount of electric charge in the port of equipment.Another kind of situation is that the end when cable is inserted in the port of equipment, and human body is when touching the metal pins on the other end of cable, and the static that human body produces can enter into port inside through cable, thereby equipment is caused electrostatic hazard.Adopt existing method of testing that equipment is carried out electrostatic discharge testing; No matter be that metal chassis or port to equipment carries out static discharge; Static gun all can only touch the outside of equipment, can't touch the inside or the inner signal pins of mainboard of port, and the ground wire that the high-pressure electrostatic that static gun produces is actually through equipment exports to the earth; And can't therefore all only be equivalent to device external is carried out electrostatic discharge testing through the inside or the inner signal pins of mainboard of port.
In sum; In realizing process of the present invention; The inventor finds to exist at least in the prior art following problem: electrostatic discharge testing scheme of the prior art only can realize electrostatic discharge testing is carried out in the equipment under test outside, and does not also have a kind of scheme that can realize equipment under test inside is carried out electrostatic discharge testing in the prior art.

Embodiment
The structural representation of a kind of electro-static discharge test device that Fig. 1 provides for the embodiment of the invention one; As shown in Figure 1; This electro-static discharge test device comprises at least one test port, and this test port is connected the port that forms for one or more pin with particular port with shell.
In the present embodiment, the pin that forms the particular port of each test port can be different.In the present embodiment, can one or more pin of particular port be connected with the shell pin to realize being connected of one or more pin and shell.Particular port can be the port identical with tested port.When the electro-static discharge test device in adopting the embodiment of the invention carries out electrostatic discharge testing to the tested port of equipment under test; Can test port be connected with the tested port of equipment under test through the test cable; Through static gun the shell of test port is carried out static discharge again; Make static get into tested port through testing cable; Because static normally gets into tested port through a right signal wire of differential lines in the test cable or through differential lines in the test cable to getting into tested port, and the signal wire in the test cable is corresponding with the pin of tested port, therefore; Test port can be connected with shell with realization for a pin in the differential pairs pins in the particular port being connected with the shell pin or the differential pairs pins in the particular port being connected with the shell pin.Wherein, differential pairs pins can be differential pairs pins of sending signal and the differential pairs pins that receives signal.
Adopting the RJ45 interface with the tested port of equipment under test below is example, and the test port of electro-static discharge test device is elaborated.
Tested port in the present embodiment is an example with the RJ45 interface.The RJ45 interface refers to the standardization by IEC, uses modular jack or plug by 8 positions (8 pin) of international connector standard definition, and in 802.3 standards, this RJ45 interface definition is the Ethernet that is used for the twisted-pair feeder transmission.Fig. 2 is the structural representation of RJ45 interface, and is as shown in Figure 2, and this RJ45 interface comprises 12 pins, specifically is defined as pin pin1 to pin12.Pin9 and pin10 are the plastics angles of RJ45 interface, and pin9 and pin10 be definition signal not, and its effect is merely the location.Pin11 and pin12 are the pins of the shell of RJ45 interface, can be described as the shell pin, and this shell is a metal shielding.These 8 pins of pin1 to pin8 are corresponding to 8 signal wires in the cable; To transmit 100,000,000 signals is example; Pin1 and pin2 are the differential pairs (TX+/TX-) that sends signal; Pin3 and pin6 are the differential pairs (RX+/RX-) that receives signal, and all the other pin4, pin5, pin7 and pin8 are not used when transmission 100,000,000 signals.
Correspondingly, adopt the RJ45 interface to equipment under test, the test cable can be for comprising 4 pairs of cables that differential lines is right, and this differential lines is to being respectively signal wire 1/2, signal wire 3/6, signal wire 4/5 and signal wire 7/8.Wherein, signal wire 1/2 is corresponding to pin1 in the RJ45 interface and pin2, and signal wire 3/6 is corresponding to pin3 in the RJ45 interface and pin6, and signal wire 4/5 is corresponding to pin4 in the RJ45 interface and pin5, and signal wire 7/8 is corresponding to pin7 in the RJ45 interface and pin8.Static can get into the pin in the corresponding RJ45 interface by right signal wire through each differential lines in the test cable.Particularly, static can get into the pin in the corresponding RJ45 interface through a signal wire of differential lines centering, also can get into two pins in the corresponding RJ45 interface simultaneously through two right signal wires of differential lines.For example; For pin1 and the pin2 in the RJ45 interface of signal wire 1/2 and correspondence, static can can get into pin1 and pin2 in the RJ45 interface through signal wire 1 and signal wire 2 through pin2 or the static that signal wire 2 gets in the RJ45 interfaces simultaneously through pin1 or the static that signal wire 1 gets in the RJ45 interface.
