Description

Circuit detects card device

Technical field

The utility model relates to a kind of circuit detection card device, and especially a kind of flexibility is high, is able to detect difference The circuit at interface detects card device.

Background technique

The method of detection circuit mainboard traditional at present is to need to do different detection cards for different mainboard interfaces, because It is different for the interface socket of many mainboards, so that the mode of connection of connection socket is also different, so to select corresponding wiring side The testing jack of formula, and be the judgement for showing different colors by LED light to make result, such test after the completion of testing Mode there are the shortcomings that have:

(1) tool kind is more, causes unnecessary waste, while using and arranging inconvenience.

(2) detection cannot show actual value, can only judge by the way that whether LED light is lighted, signaling point is short to signaling point Road is unable to measure, and line impedance is bigger than normal to be unable to measure.

(3) as server product upgrades, the type at interface constantly increases, and the PIN foot at interface is more and more, transmission Rate and semaphore request are also higher and higher, so current tool has been unable to satisfy present product.

It is high that in view of this, the present invention provides a kind of flexibilities, is able to detect the circuit detection card device at different interfaces.

Summary of the invention

The technical problems to be solved in the utility model is to be to provide a kind of flexibility height, is able to detect the electricity at different interfaces Detect card device in road.

In order to solve the above technical problems, a kind of circuit detects card device, be used to detect a motherboard circuit opens short-circuit feelings Condition, an interface socket is provided on the motherboard circuit, and circuit detection card device includes:

One free interface module is used for the free winding displacement connection of a testing jack, which can be with this The electrical connection of interface socket, the testing jack other end are connected with several connecting lines, are provided in the free interface module several A interface, the connecting line can be electrically connected with the interface, which can be according to the different selections pair of the interface socket type The testing jack answered, and the quantity of the interface is more than or equal to the quantity of the connecting line；

One main control module is used to control the operating of whole device, which is electrically connected the master control molding Block, the main control module include: Single port scan module, an AD conversion module and a contrast module, the port scan module electricity The AD conversion module is connected, which is electrically connected the contrast module, and the port scan module is for scanning mainboard electricity The analog signal scanned is converted to a digital signal by the AD conversion module by road, should by contrast module comparison Digital signal and a preset signals obtain a test result；And

One display module is electrically connected the main control module, and the display module is for showing the test result.

Preferably, the free interface module, the main control module and the display module are integrated on one block of plate and use.

When using circuit detection card device, first according to the type of the interface socket on the motherboard circuit, phase is selected The type for the testing jack answered, then several connecting lines of the testing jack are correctly connected in the free interface module The testing jack is inserted into the relevant test of interface socket progress after the completion of connection and obtains relevant survey by several interfaces The test to the motherboard circuit is completed in test result.

Compared to the prior art, the utility model circuit detection card device can by the design of the free interface module It is different according to interface socket on the motherboard circuit, select the corresponding testing jack and by the connection on the testing jack Line correctly connects the interface in the free interface module, realizes and is detected card using the same circuit and selected the different tests Socket can test the motherboard circuit with the different interface sockets, such to set to reach Universal combination test effect It is high to count flexibility, the idle waste of tool can be reduced, is conducive to save cost.

[Detailed description of the invention]

Fig. 1 is the module composition figure that the utility model circuit detects one embodiment of card device.

[specific embodiment]

Refering to Figure 1, the utility model provides a kind of circuit detection card device, it is used to detect a motherboard circuit (not shown) opens short-circuit conditions, and an interface socket (not shown) is provided on the motherboard circuit, which detects card device packet It includes:

One free interface module 1 is used for the free winding displacement connection of a testing jack 4, and 4 one sections of the testing jack can be with Interface socket electrical connection, 4 other end of testing jack are connected with several connecting lines 41, are arranged in the free interface module 1 There are several interfaces 11, which can be electrically connected with the interface 11, which can be according to the interface socket type Difference select the corresponding testing jack 4, and the quantity of the interface 11 is more than or equal to the quantity of the connecting line 41；

One main control module 2, is used to control the operating of whole device, which is electrically connected the main control Module 2, the main control module 2 include: Single port scan module 21, an AD conversion module 22 and a contrast module 23, the port Scan module 21 is electrically connected the AD conversion module 22, which is electrically connected the contrast module 23, the port scan mould The analog signal scanned is converted to a number by the AD conversion module 22 and believed by block 21 for scanning the motherboard circuit Number, which is compared by the contrast module 23 and a preset signals obtain a test result；And
