Description

Technical Field

[0001] The present application relates to the technical field of computer equipment, and in particular to a connector terminal structure and a terminal state control method. Background Art

[0002] A RAM stick, or random access memory module, is a storage device installed on a computer motherboard. The RAM stick serves as a temporary data storage device that can read and write data quickly. A RAM stick connector is an interface used to connect the RAM stick to the motherboard, ensuring that the computer can read and write data normally. It provides a stable electrical connection, allowing the CPU (Central Processing Unit) to quickly access data in the RAM stick, thereby improving the overall performance of the computer.

[0003] In some related technologies, in order to ensure a stable connection between the memory stick and the motherboard, a certain plug-in force is required for the memory connector during installation and removal. For example, the plug-in force of the DDR5 memory connector currently in use is fixed when production is completed. When the plug-in force is below 10kg, production line workers or automated tools will save effort when installing or removing the memory, but the contact performance between the connector terminal and the gold finger will be reduced, affecting the signal transmission quality; when the plug-in force exceeds 20kg, it will be more laborious and difficult to complete manually. In the scenario of automated machine plug-in and pull-out, when the plug-in force is too large, the machine will alarm due to excessive torque, thereby affecting the efficiency of the entire production line.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] In one embodiment, Figure 1 As shown, a connector terminal structure is provided, wherein the connector is a DIMM connector and the memory stick is a DIMM (Dual-Inline-Memory-Modules) as an example for explanation, comprising a connector housing 1, two connector terminals 2 and a control circuit 4, wherein the bottoms of the two connector terminals 2 are fixedly connected to the connector housing 1 at intervals, and a memory stick 3 is movably clamped between the two connector terminals 2, and the DIMM memory stick is vertically plugged between the two connector terminals 2, wherein the connector terminals 2 are shape memory alloys plated with a metal layer, and a heating component 5 is wrapped on the connector terminals 2, wherein the heating component 5 in this embodiment is configured as a resistance wire, and both ends of the heating component 5 are electrically connected to the control circuit 4. It should be noted that, as shown in FIG. Figure 2As shown, the metal layer outside the connector terminal 2 includes but is not limited to a copper layer or a gold layer, the memory stick 3 is a rectangular parallelepiped, and gold fingers 6 are respectively provided on both sides of the memory stick 3 in the plugging direction toward the two connector terminals 2 .

[0043] like Figure 3 As shown, before the DIMM memory stick 3 is connected to the connector, the initial shape of the DIMM connector terminal 2 is in an inclined state, that is, the initial distance between the two connector terminals 2 is smaller than the distance between the gold fingers 6 on both sides, so that after the memory stick 3 is inserted into the connector, the connector terminals 2 on both sides can elastically contact with the gold fingers 6, thereby forming a positive pressure on the memory stick 3 to ensure a stable connection between the memory stick 3 and the connector.

[0044] Further, such as Figure 4 As shown, the positive and negative electrodes of the control circuit 4 are respectively connected to the two ends of the heating component 5, so that the control circuit 4 outputs current to the heating component 5 to heat the heating component 5. The heat is conducted to the connector terminal 2 through the heating component 5 to heat the connector terminal 2 made of shape memory alloy. The connector terminal 2 heated to a preset temperature is deformed so that the two connector terminals 2 move away from each other. At this time, the friction between the gold fingers 6 outside the memory stick 3 and the connector terminals 2 of the DIMM connector is greatly reduced. The DIMM memory stick 3 is inserted between the two connector terminals 2. There is no positive pressure between the DIMM connector and the DIMM gold fingers 6. Therefore, the friction between the DIMM terminal and the gold fingers 6 is almost zero, thereby greatly reducing the insertion and extraction force.

[0045] At the same time, after the control circuit 4 disconnects the current, the two connector terminals 2 move toward each other so that the shape memory alloy connector terminals 2 return to their initial shape, and the gold fingers 6 on both sides of the memory stick 3 elastically contact the corresponding connector terminals 2 respectively to ensure the stability of the electrical connection, thereby ensuring the signal transmission quality. The above method can realize the insertion of DIMM under a small plug-in and pull-out force, and can achieve a high-reliability electrical connection after plugging.

[0046] In a specific embodiment, the upper part of the connector has a connector shell 1, the bottoms of the two connector terminals 2 are fixedly connected to the connector shell 1, the connector terminals 2 are sequentially provided with a base section 201 and an extension section 202 in a direction away from the connector shell 1, and the heating component 5 is attached to the connector terminal 2 of the base section 201, wherein the length ratio of the base section 201 to the extension section 202 ranges from 1:0.5 to 1:5; in this embodiment, the length ratio of the base section 201 to the extension section 202 is 1:1.

[0047] It should be noted that a bending portion is provided in the middle of the extension section 202, and the opening of the bending portion is toward the direction in which the two connector terminals are away from each other. The setting of the bending portion increases the contact area between the connector terminal 2 and the gold finger 6 on the memory stick 3, thereby strengthening the stable connection between the memory stick 3 and the connector.

[0048] In this embodiment, in order to further achieve precise control of the shape of the connector terminal 2, a control circuit 4 is provided including a temperature detection component 401, a power supply 402, a drive circuit 403 and a baseboard management control 404, wherein the temperature detection component is configured as a temperature sensor, and the temperature detection component 401 is placed in the connector housing 1, and the temperature detection component 401 is used to detect the temperature of the connector terminal 2, the temperature detection component 401 is also communicatively connected to the baseboard management controller 404 via an i2C bus, the power supply 402 is placed in the connector housing 1, and the positive and negative poles of the power supply 402 are electrically connected to the two ends of the heating component 5 respectively, the drive circuit 403 is communicatively connected to the baseboard management controller 404 via a control signal, and one control circuit 4 can be connected to several connector terminals 2 at the same time, so as to achieve that the deformation states of several connector terminals 2 can be controlled simultaneously by one control circuit 4.

[0049] Among them, Figure 5 As shown, the driving circuit 403 in this embodiment includes two transistors 4031 and a micro control unit 4032. The upper transistor 4031 is an N-channel IGBT (Insulate-Gate Bipolar Transistor), and the lower one is a P-channel IGBT. The G poles of the two IGBTs are connected to each other and connected to the GPIO pin of the micro control unit 4032. The baseboard management controller 404 sends a control signal to the micro control unit 4032 according to the temperature detected by the temperature detection component 401, and the control signal is used to control the output current of the driving circuit 403 or disconnect the output current.

[0050] Furthermore, when the pin level of the microcontroller unit 4032 is high, the upper transistor 4031 is turned on and the lower transistor 4031 is turned off. At this time, current is output to the heating component 5, and the connector terminal 2 is in a heating state; when the pin level of the microcontroller unit 4032 is low, the upper transistor 4031 is turned off and the lower transistor 4031 is turned on. At this time, the output current to the heating component 5 is stopped and it is in a closed state. Through this structure, the duty cycle of the control signal can be adjusted to achieve regulation of the heating intensity of the heating component 5.

[0051] Specific implementation process: first confirm the connector to which the memory stick 3 is to be plugged, adjust the driving circuit 403 through the baseboard management controller 404 to pass current to the heating component 5, and the heating component 5 conducts current to the connector terminal 2 to achieve heating of the connector terminal 2, and collects the temperature of the connector terminal 2 through the temperature detection component 401. When the collected temperature reaches the preset temperature, the two connector terminals 2 move away from each other at this time, so that the friction between the DIMM terminal and the gold finger 6 is almost zero, and the memory stick 3 is plugged between the two connector terminals 2. After the control circuit 4 disconnects the current, the two connector terminals 2 move toward each other to achieve the shape memory alloy connector terminal 2 to restore to the initial shape, and the gold fingers 6 on both sides of the memory stick 3 are elastically contacted with the corresponding connector terminals 2. The scheme in this implementation can not only achieve a small plug-in and pull-out force when the memory stick 3 is plugged in and out, which is convenient for assembly, but also ensure that there is a large positive pressure between the assembled memory stick 3 and the connector terminal 2 to ensure the stability of the electrical connection, thereby ensuring the signal transmission quality.

[0052] In one embodiment, Figure 6 As shown, a terminal state control method is provided, which is applied to the connector terminal structure as described above, and is described by taking the memory stick 3 as a DIMM (Dual-Inline-Memory-Modules) and the connector as a DIMM connector as an example, wherein the connector terminal structure includes at least two connector terminals 2, a heating component 5, and a control circuit 4, wherein the control circuit 4 includes a temperature detection component 401, a drive circuit 403, and a baseboard management controller 404, and the method includes the following steps:

[0053] Step 101 : adjusting the substrate management controller 404 to control the driving circuit 403 to pass current to the heating component 5 , so as to heat the connector terminal 2 wrapped by the heating component 5 .

[0054] Step 102: collecting the real-time temperature of the connector terminal 2 through the temperature detection component 401, and comparing and analyzing the real-time temperature with a preset first threshold;

[0055] Step 103 : When the real-time temperature exceeds a first threshold, the two connector terminals 2 move away from each other, and the memory stick 3 is adjusted to be inserted between the two connector terminals 2 .

[0056] The baseboard management controller 404 obtains the real-time temperature of the connector terminal 2 collected by the temperature detection component 401, and compares and analyzes the real-time temperature with the first threshold. If the real-time temperature value exceeds the first threshold, it means that the connector terminal 2 has reached the standard for deformation. At this time, the two connector terminals 2 can easily move to both sides during the insertion of the memory stick 3, which facilitates the connection between the memory stick 3 and the connector.

[0057] Step 104 , the baseboard management controller 404 controls the driving circuit 403 to be disconnected, and the two connector terminals 2 move toward each other, and the gold fingers 6 on the memory stick 3 are in elastic contact with the connector terminals 2 .

[0058] After the memory stick 3 is inserted between the two connector terminals 2, the gold fingers 6 on the outside of the memory stick 3 are in elastic contact with the connector terminals 2 to achieve electrical connection between the memory stick 3 and the connector. At this time, the baseboard management controller 404 controls the drive circuit 403 to disconnect, that is, stops supplying current to the heating component 5. At this time, the temperature of the connector terminals 2 drops below the first threshold, and the two connector terminals 2 move toward each other and return to their initial positions. At the same time, the gold fingers 6 on the memory stick 3 are in elastic contact with the connector terminals 2.

[0059] It should be noted that, in this embodiment, before the two connector terminals 2 move away from each other, the initial distance between the two connector terminals 2 is maintained; the initial distance between the two connector terminals 2 is smaller than the minimum distance between the gold fingers 6 on both sides of the memory stick 3, further ensuring that there is positive pressure between the connector terminal 2 and the memory stick 3 after returning to the initial position, that is, ensuring that the terminal and the DIMM gold fingers 6 return to a tightly fitted state, thereby achieving the stability of the stable electrical connection.

[0060] In a specific embodiment, in order to achieve accurate control of the terminal state of the connector to be plugged, a second threshold and a third threshold are preset, wherein the second threshold is greater than the value of the first threshold, and the third threshold is less than the value of the first threshold. When the real-time temperature exceeds the second threshold, the duty cycle of the first preset circuit signal sent by the baseboard management controller 404 to the drive circuit 403 is adjusted to reduce the output current of the drive circuit 403 by the duty cycle of the first preset circuit signal. When the temperature of the connector terminal 2 is too high during the heating process, the output current of the drive circuit 403 is reduced by adjusting the duty cycle of the PWM wave, thereby reducing the heat generation power of the heating component 5, that is, reducing the temperature of the terminal, so as to avoid the temperature of the connector terminal 2 being too high.

[0061] Alternatively, when the real-time temperature is lower than the third threshold, the duty cycle of the second preset circuit signal sent by the baseboard management controller 404 to the drive circuit 403 is adjusted to increase the output current of the drive circuit 403 through the duty cycle of the second preset circuit signal. When the temperature of the connector terminal 2 is too low during the heating process, that is, lower than the third threshold, the output current of the drive circuit 403 is increased by the duty cycle of the PWM wave, thereby increasing the heat generation power of the heating component 5, that is, increasing the temperature of the terminal.

[0062] Furthermore, the connector terminals 2 are provided with a plurality of them, and the power supply 402 in the driving circuit 403 is connected in parallel with the heating components 5 in the plurality of the connector terminals 2, that is, the shape states of the plurality of connector terminals 2 are realized simultaneously through the control circuit 4 in this embodiment, specifically including: setting the connector terminals 2 to have serial numbers respectively, and marking the temperature numbers in the baseboard management controller 404; the temperature numbers are associated with the serial numbers to form marking numbers, and the marking numbers are used to indicate the temperature detection components 401 corresponding to the connector terminal 2; in response to the real-time temperature collected by one of the temperature detection components 401 exceeding the first threshold value, the serial number of the connector terminal 2 to be plugged in corresponding to the temperature detection component 401 is obtained by querying the marking number; and the connector terminal 2 to be plugged in is configured to be plugged in correspondingly to the corresponding memory stick 3.

[0063] In this embodiment, the marking number of the temperature detection component 401 associated with the connector to be plugged in is used to adjust the driving circuit 403 through the baseboard management controller 404 to pass current to the heating component 5, and the heating component 5 conducts current to the connector terminal 2 to achieve heating of the connector terminal 2. The temperature of the connector terminal 2 is collected by the temperature detection component 401. When the collected temperature reaches the preset temperature, the two connector terminals 2 move away from each other at this time, so that the friction between the DIMM terminal and the gold finger 6 is almost zero. At this time, the memory stick 3 is plugged between the two connector terminals 2. After the control circuit 4 disconnects the current, the two connector terminals 2 move towards each other to achieve the shape memory alloy connector terminal 2 to restore to its initial shape, and the gold fingers 6 on both sides of the memory stick 3 are elastically in contact with the corresponding connector terminals 2 respectively.
