It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0043] Embodiment 1

[0044] Figure 1 FIG. 1 is a block diagram of an insertion state detection module for a memory stick plug-in test provided by an embodiment of the present invention, such as Figure 1 As shown, this embodiment provides an insertion state detection module for a memory stick plug-in test, the insertion state detection module is integrated on a memory stick plug-in test motherboard, the memory stick plug-in test motherboard is provided with a memory slot 1, and the insertion state detection module includes:

[0045] Two detection contact groups, both detection contact groups are arranged in the memory slot, each detection contact group includes two detection contacts 2, and the two detection contacts 2 of each group are normally closed structures, such as Figure 2 As shown;

[0046] The detection unit, each group of two detection contacts 2 is electrically connected to the detection unit, and is used to determine the opening and closing state of the two detection contacts 2 of each group, and to display the opening and closing state of the two detection contacts 2 of each group.

[0047] In this embodiment, the memory slot 1 is divided into a pin area and a non-pin area. The pin area is located in the middle of the memory slot 1, and the non-pin area is located at both ends of the memory slot 1, that is, the pin area is located between the two non-pin areas. The pin area of ​​the conventional memory slot 1 (socket) has 288 pins (288-pin). 144 pins are arranged on one side of the memory slot 1, and 144 pins are arranged on the other side. There is a gap between each pair of pins. When the memory stick is inserted into the memory slot 1, the pins contact the gold fingers on the memory stick. , realizing the electrical connection between the memory stick and the pins; after the memory stick is inserted into the memory slot 1, the insulating area of ​​the memory stick is located in the non-pin area, at this time, the two groups of detection contact groups are respectively arranged at the bottom of the two non-pin areas, and the two detection contacts 2 of each group are respectively fixed on the inner wall of the memory slot; since the two detection contacts 2 of each group are normally closed, that is, when the memory stick is not inserted into the memory slot 1, the two detection contacts 2 of each group are in contact with each other, and when the memory stick is fully inserted into the memory slot 1, the two detection contacts 2 of the two groups will be separated.

[0048] Therefore, when the present invention tests the memory stick, after the operator inserts the memory stick into the memory slot 1 of the test motherboard, since the memory slot 1 is provided with two groups of detection contact groups, and the two detection contacts 2 of each group are of a normally closed structure, when the memory stick is fully inserted into the memory slot 1, the two detection contacts 2 of the normally closed structure will separate, and when the memory stick is tilted after insertion or is not fully inserted, there will be two detection contacts 2 that remain in the connected state; at this time, the detection unit can detect the open and closed state of the two detection contacts 2 of each group, and can determine whether the memory stick is fully inserted into the memory slot 1; therefore, before the test machine starts to execute the test task, the operator can understand whether the contact between the memory stick and the memory slot 1 is good, thereby eliminating the failure caused by poor contact and greatly improving the pass rate; and it can avoid repeated testing and save a lot of time cost for repeated testing.

[0049] As a further optimization of this embodiment, the two detection contacts 2 in each group are both spring pieces, which are made of copper material and have good elasticity.

[0050] As a further optimization of this embodiment, Figure 3 As shown, the detection unit includes: a power module, a logic controller and an indicator light;

[0051] The power module is used to provide working power for the logic controller, the power output end of the power module is electrically connected to the power input end of the logic controller, and the four detection contacts 2 are electrically connected to the four signal ports of the logic controller respectively; the power input end of the indicator light is electrically connected to the power output end of the logic controller;

[0052] The logic controller is used to: obtain the level signals of the four signal ports, determine the opening and closing states of the two detection contacts 2 of each group according to the level signals of the four signal ports, generate a brightness adjustment instruction based on the opening and closing states of the two detection contacts 2 of each group, adjust the brightness level of the indicator light based on the brightness adjustment instruction, and display the opening and closing states of the two detection contacts 2 of each group with the brightness level of the indicator light.

[0053] In this embodiment, the four signal ports of the logic controller are A+ port, A- port, B+ port and B- port respectively; the logic control can adjust the voltage output by the power output end of the logic control according to the brightness adjustment instruction to realize the brightness adjustment of the indicator light, so as to facilitate the display of different opening and closing states and facilitate the operator to observe.

[0054] For the first detection contact group: the A+ port of the logic controller is electrically connected to one of the detection contacts 2 of the first detection contact group, and the A- port is electrically connected to the other detection contact 2 of the first detection contact group. After the A+ port outputs a high level, when the two detection contacts 2 of the first group are closed, the A- port can detect a high level, and when the two detection contacts 2 of the first group are disconnected, the A- port can detect a low level.

[0055] For the second group of detection contacts: the B+ port of the logic controller is electrically connected to one of the detection contacts 2 of the second group of detection contacts, and the B- port is electrically connected to the other detection contact 2 of the second group of detection contacts. After the B+ port outputs a high level, when the two detection contacts 2 of the second group are closed, the B- port can detect a high level, and when the two detection contacts 2 of the second group are disconnected, the B- port can detect a low level.

[0056] Therefore, the opening and closing states of the two detection contacts 2 of the two groups can be determined according to the level changes of the A-port and the B-port. When the two detection contacts 2 of the two groups are disconnected at the same time, it indicates that all the memory sticks are inserted into the memory slots 1, thus avoiding poor contact failure caused by the memory sticks being inserted offset or not fully inserted.

[0057] As a further optimization of this embodiment, the opening and closing states of the two detection contacts 2 of each group include: the two detection contacts 2 are in the connected state or the two detection contacts 2 are in the separated state, and the brightness level includes: the indicator light is fully on, the indicator light is slightly on, or the indicator light is off;

[0058] Among them, when the two detection contacts 2 of the two groups are in the connected state, the brightness level is that the indicator light is off; when the two detection contacts 2 of one group are in the connected state and the two detection contacts 2 of the other group are in the separated state, the brightness level is that the indicator light is slightly bright; when the two detection contacts 2 of the two groups are in the separated state, the brightness level is that the indicator light is fully bright.

[0059] In this embodiment, the indicator light may be an LED light, which may emit colored light, such as yellow light. When the two detection contacts 2 of the two groups are not separated, the LED light is off, indicating that the memory stick is not inserted into the memory slot 1, for example, it is placed between the two slots, or is lightly placed in the memory slot 1 but not pressed down.

[0060] When only one set of two detection contacts 2 are not separated, the LED light is dark yellow, indicating that the memory stick is inserted into the memory slot 1, but the level is not flat, one side is high and the other side is low (this situation occurs most frequently in Failure);

[0061] When the two detection contacts 2 of the two groups are separated, the LED light is yellow, indicating that the memory stick is normally inserted into the memory slot 1.

[0062] The insertion state detection module of the present invention has the advantages of simple structure, convenient insertion state detection and strong practicality.
