Abstract
The utility model provides a memory slot detector. A power adaptor comprises a pin extension socket, a plurality of leads, and a plurality of display lamps; a plurality of test pins are arranged on the pin extension socket, and are mutually matched with corresponding internal pins in a memory slot; the number of the leads is the same with that of the test pins, and the leads are electrically connected with each test pin respectively; and the number of the display lamps is the same with that of the leads, and each display lamp is electrically connected with each lead respectively. Compared with the prior art, a checker does not need to use a multimeter to measure the memory slot and external pins adjacent to a north bridge one by one through utilizing the memory slot detector, thereby detecting conveniently; and in addition, the internal pins of the memory slot can be detected, thereby achieving comprehensive detection.
Description
[technical field]
The relevant a kind of memory slot detector of the utility model, particularly a kind of portable memory slot detector.
[background technology]
When engineering analysis, run into booting computer and do not have apparent fault through regular meeting; measuring voltage and coherent signal are normal; and BIOS is in work; the Debug card is shown as the internal memory cisco unity malfunction; just need this moment the circuit between measurement memory slot and the north bridge whether normal; usually the practice is with multimeter the external pin of memory slot and north bridge adjacent part to be measured one by one, and the method needs long time too much because of the memory slot number of pins and is easy to make mistakes.
The maintenance personal also can meet this situation when the maintenance trouble mainboard, according to above method, the maintenance personal can spend a lot of time, and not necessarily can measure problem, therefore can accumulate a lot of down iron plates that show of not having.
And, more than be that the external pin of memory slot and north bridge adjacent part is measured, if the inside pin oxidation of memory slot is inconvenient to go deep into owing to multimeter, we just can't measure.
In view of this, be necessary to provide a kind of memory slot detector in fact, utilize this memory slot detector tester to need not the external pin of memory slot and north bridge adjacent part to be measured one by one with multimeter, can reach the convenience of detection, on the other hand, can also the inside pin of memory slot be detected, can reach the comprehensive of detection.
[summary of the invention]
The purpose of this utility model is to provide a kind of memory slot detector, utilize this memory slot detector tester to need not the external pin of memory slot and north bridge adjacent part to be measured one by one with multimeter, can reach the convenience of detection, on the other hand, can also the inside pin of memory slot be detected, can reach the comprehensive of detection.
For reaching above-mentioned purpose, the memory slot detector that the utility model provides, this power-supply adapter comprises:
One pin insert row which is provided with plurality of test pins, and each test pin inside pin corresponding with memory slot cooperatively interacts;
Some leads, the number of these leads is identical with above-mentioned test pin number, and each lead electrically connects with a test pin respectively;
Several display lamps, the number of these display lamps is identical with above-mentioned lead number, and each display lamp electrically connects with a lead respectively.
Especially, above-mentioned display lamp is a light emitting diode, and each display lamp is located on the display board, and on display board each display lamp is carried out label, so can make things convenient for the tester to understand which the in-problem inner pin of memory slot is.
Compared with prior art, utilize memory slot detector tester of the present utility model to need not the external pin of memory slot and north bridge adjacent part to be measured one by one with multimeter, can reach the convenience of detection, on the other hand, can also the inside pin of memory slot be detected, can reach the comprehensive of detection.
[description of drawings]
Fig. 1 illustrates the circuit diagram into one preferred embodiment of the utility model memory slot detector.
[embodiment]
See also Fig. 1, Fig. 1 illustrates the circuit diagram into one preferred embodiment of the utility model memory slot detector.
For reaching above-mentioned purpose, the memory slot detector that the utility model provides, in present embodiment, this memory slot detector comprises:
One pin insert row which is provided with plurality of test pins 1, and each test pin 1 inside pin 2 corresponding with memory slot cooperatively interacts;
Some leads 3, the number of these leads 3 is identical with above-mentioned test pin 1 number, and each lead 3 electrically connects with a test pin 1 respectively;
Several display lamps 4, the number of these display lamps 4 is identical with above-mentioned lead 3 numbers, and each display lamp 4 electrically connects with a lead 3 respectively.
Certainly, above-mentioned each display lamp 4 all is in series with a current-limiting resistance 5, and each memory slot is to all there being a resistance 6 between mainboard ground.
Here, above-mentioned display lamp 4 is a light emitting diode, and each display lamp 4 is located on the display board, and on display board each display lamp 4 is carried out label, so can make things convenient for the tester to understand which the in-problem inner pin of memory slot is.
In test time, if during inner pin 2 shorted to earths of certain of above-mentioned memory slot, this inside pin 2 is zero to the resistance between mainboard ground 6, and display lamp 4 that then should inside pin 2 correspondences can be brighter much than other display lamp 4.And if during the empty weldering of certain inner pin 2,4 of the display lamps of these inside pin 2 correspondences can conducting and not luminous.Thereby we can judge whether each inner pin 2 is normal by above-mentioned phenomenon.
Compared with prior art, utilize memory slot detector tester of the present utility model to need not to use universal meter External pin to memory slot and north bridge adjacent part is measured one by one, can reach the convenience of detection, On the other hand, can also the inside pin 2 of memory slot be detected, can reach the comprehensive of detection.
