Description

Technical Field

[0001] This invention relates to the field of pin detection technology, and in particular to a terminal detection device, a terminal detection assembly, a slot connector, and an apparatus. Background Technology

[0002] A slot connector is a connector that serves as the electrical connection medium between a circuit board and the motherboard, consisting of a slot plastic and metal terminals. Multiple metal terminals are inserted into the slot plastic. After the external circuit board is inserted into the slot plastic, it achieves signal transmission and electrical connection with the motherboard through the metal terminals. Pin collapse refers to the phenomenon where the metal terminals in a slot connector collapse, deform, bend, or break due to external force.

[0003] With the continuous increase in information processing speed and system functions, the number of terminal pins on a single slot connector has increased significantly, while the pin spacing has decreased to achieve high-density connections. For example, compared to the traditional PCIe X16 slot connector (164 pins, 1.0mm pin spacing), the existing GenZ 8C slot connector has expanded to 280 pins, with the pin spacing reduced to 0.6mm, resulting in a significant increase in terminal density. During board insertion and removal, the high-density slot connector, due to the large number of terminals and small spacing, increases the probability of pin failure.

[0004] Existing slot connectors lack effective detection methods for pin failure events. When a signal terminal fails, system functionality will fail, requiring maintenance personnel to spend considerable time troubleshooting each fault, often relying on visual inspection to confirm if a pin failure is the cause. This inefficient troubleshooting process impacts system maintainability. When a ground terminal fails, because multiple ground terminals are typically connected in parallel in a circuit, the system can still function normally even if a single ground terminal fails, easily masking the pin failure and making it difficult to detect in time. In this situation, the failed terminal may shift due to vibration during handling or use, short-circuiting adjacent terminals and causing a short circuit; or the failed terminal may break due to metal fatigue, with broken pieces randomly scattered inside the chassis, potentially causing electrical short circuits or even burning out the entire device, posing a serious safety hazard. Summary of the Invention

[0005] The main objective of this invention is to provide a terminal detection device, a terminal detection assembly, a slot connector, and an equipment, which are designed to automatically detect whether the terminals inside the connector slot plastic are abnormal or deformed.

[0009] In one embodiment, the first detection component is an L-shaped conductive sheet, and the second detection component is a groove-shaped conductive sheet; or, The first detection component is a groove-shaped conductive sheet, and the second detection component is an L-shaped conductive sheet.

[0010] In one embodiment, the insulating layer is any one of a polyimide insulating layer, a polyester insulating layer, an epoxy resin insulating layer, an organosilicon insulating layer, or a ceramic insulating layer.

[0011] The present invention also provides a terminal detection assembly, comprising: a detection circuit and a terminal detection device as described in any of the preceding claims; The detection circuit is connected to the first conductive pin and the second conductive pin of the terminal detection device, respectively. The detection circuit is used to determine that the terminal detection device is being squeezed by a pin when an electrical connection path is detected between the first conductive pin and the second conductive pin. The detection circuit is also used to determine that the terminal detection device is not squeezed by the pin when it is detected that no electrical connection path is established between the first conductive pin and the second conductive pin.

[0012] In one embodiment, the first conductive pin of the terminal detection device is grounded, and the detection circuit includes: Resistors, power supply terminals, and control circuitry; The first end of the resistor is connected to the power supply terminal, and the second end of the resistor is connected to the control circuit and the second conductive pin, respectively. If no electrical connection is established between the first conductive pin and the second conductive pin, the second conductive pin is connected to the power supply terminal through the resistor, and the control circuit detects that the second conductive pin is in a first level state. When an electrical connection is established between the first conductive pin and the second conductive pin, the second conductive pin is grounded through the first conductive pin. The control circuit detects that the second conductive pin is in a second level state, and the control circuit generates an alarm signal based on the second level state.

[0013] The present invention also proposes a slot connector, including a terminal detection device as described in any of the preceding claims; The slot connector includes a slot plastic and a connecting terminal disposed within the slot connector, wherein the terminal detection device is disposed relative to the slot connector; When the slot plastic is inserted into the pin, the pin establishes an electrical connection path with the connection terminal and the pin presses against the terminal detection device to establish an electrical connection path for the terminal detection device; When the pin is not inserted into the slot plastic, the pin and the connection terminal do not establish an electrical connection path, and the pin does not press against the terminal detection device, so that the terminal detection device does not establish an electrical connection path.

[0014] In one embodiment, the slot connector is any one of a PCIe slot, a Gen Z slot, an MCIO slot, a Slim-SAS slot, or a DDR memory slot.

[0015] The present invention also proposes an apparatus comprising: a terminal detection device as described in any of the preceding claims; and / or, a terminal detection assembly as described in any of the preceding claims; and / or, a slot connector as described in any of the preceding claims.

[0016] The technical solution of this invention employs a first detection component, a second detection component, and a movable metal contact. It utilizes the positional changes of the movable metal contact under compressed and natural states to determine whether an electrical connection is established between the first and second detection components. When the connecting piece of the movable metal contact is compressed, the first contact point connects to the second component, and the second contact point connects to the fourth component, establishing an electrical connection between the first and second detection components. When the connecting piece is not compressed, there is a gap between the second component and the first contact point of the movable metal contact, and a gap between the fourth component and the second contact point of the movable metal contact, indicating no electrical connection is established between the first and second detection components. This terminal detection device achieves the determination of electrical connection continuity through a simple mechanical structure, eliminating the need for manual visual inspection, improving insertion efficiency, and its simple structure makes it easy to integrate into various slot connectors. Furthermore, the insulating layers on the surfaces of the first and third components prevent accidental contact between the first and second contact points of the movable metal contact in an uncompressed state, thus ensuring more reliable detection results.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] A slot connector is a connector that serves as the electrical connection medium between a circuit board and the motherboard, consisting of a slot plastic and metal terminals. Multiple metal terminals are inserted into the slot plastic. After the external circuit board is inserted into the slot plastic, it achieves signal transmission and electrical connection with the motherboard through the metal terminals.

[0023] With the continuous increase in information processing speed and system functions, the number of terminal pins on a single slot connector has increased significantly, while the pin spacing has decreased to achieve high-density connections.

[0024] Existing slot connectors lack effective detection methods for pin failure events.

This inefficient troubleshooting process impacts system maintainability.

[0025] Therefore, the present invention proposes a terminal detection device, which aims to automatically detect whether the terminals inside the connector slot plastic are abnormal or deformed.

[0026] Please see Figures 1 to 7 In one embodiment of the present invention, the terminal detection device 100 is applied to a slot connector 300. The slot connector 300 has a slot plastic 50 and multiple terminals inside. An external circuit board is electrically connected to the motherboard by inserting into the slot connector 300. The device includes: The first detection component 10 includes a first component 11, a second component 12, and a first conductive pin 13; the surface of the first component 11 is an insulating layer. The second detection component 20 includes a third component 21, a fourth component 22, and a second conductive pin 23; the surface of the third component 21 is an insulating layer. The movable metal contact 30 is disposed between the first detection component 10 and the second detection component 20. The movable metal contact 30 includes a first contact 31, a second contact 32 and a connecting piece 33. When the connecting piece 33 is compressed, the first contact 31 of the movable metal contact 30 is connected to the second component 12, and the second contact 32 of the movable metal contact 30 is connected to the fourth component 22, so that an electrical connection path is established between the first detection component 10 and the second detection component 20. When the connecting piece 33 is not compressed, the first component 11 abuts against the first contact angle 31 of the movable metal contact 30, and there is a gap between the second component 12 and the first contact angle 31 of the movable metal contact 30, so that no electrical connection is established between the first detection component 10 and the second detection component 20; and / or, When the connecting piece 33 is not compressed, the third component 21 abuts against the second contact 32 of the movable metal contact 30, and there is a gap between the fourth component 22 and the second contact 32 of the movable metal contact 30, so that no electrical connection path is established between the first detection component 10 and the second detection component 20.

[0027] Optionally, the terminal detection device 100 includes a first detection component 10, a second detection component 20, and a movable metal contact 30. The first detection component 10 is disposed on one side of the bottom of the slot plastic 50 and includes a first component 11, a second component 12, and a first conductive pin 13. The first component 11 is fixedly connected to the second component 12, and an insulating layer is provided on the surface of the first component 11. One end of the first conductive pin 13 is connected to the first component 11, and the other end extends outward from the first detection component 10 for connecting to an external circuit. The second detection component 20 is disposed on the other side of the bottom of the slot plastic 50 and includes a third component 21, a fourth component 22, and a second conductive pin 23. The third component 21 is fixedly connected to the fourth component 22, and an insulating layer is provided on the surface of the third component 21. One end of the second conductive pin 23 is connected to the third component 21, and the other end extends outward from the second detection component 20 for connecting to an external circuit. The movable metal contact 30 is disposed between the first detection component 10 and the second detection component 20, and is an elastic conductive sheet, including a first contact 31, a second contact 32, and a connecting piece 33. The connecting piece 33 is located in the middle area of ​​the movable metal contact piece 30. The first contact 31 is connected to the end of the connecting piece 33 near the first detection component 10 and extends in the direction of the first detection component 10. The second contact 32 is connected to the end of the connecting piece 33 near the second detection component 20 and extends in the direction of the second detection component 20.

[0028] Optionally, in the natural state where the connecting piece 33 of the movable metal contact 30 is not compressed, the first contact 31 of the movable metal contact 30 abuts against the first component 11, and a gap is provided between the first contact 31 and the second component 12; the second contact 32 of the movable metal contact 30 abuts against the third component 21, and a gap is provided between the second contact 32 and the fourth component 22. Because both the surface of the first component 11 and the surface of the third component 21 are provided with an insulating layer, there is no electrical connection between the first contact 31 and the first component 11 and between the second contact 32 and the third component 21. In this state, the first conductive pin 13 and the second conductive pin 23 are in an open circuit state, and no electrical connection path is established between the first detection component 10 and the second detection component 20.

[0029] Optionally, when the connecting piece 33 of the movable metal contact 30 is under pressure, the connecting piece 33 deforms under force. Since the first contact 31, the second contact 32, and the connecting piece 33 are an integral structure of the same movable metal contact 30, and the first contact 31 and the second contact 32 are fixedly connected by the connecting piece 33, the deformation of the connecting piece 33 causes the first contact 31 and the second contact 32 to move synchronously. The first contact 31 moves towards the second component 12 and contacts the second component 12 as the connecting piece 33 deforms. The second contact 32 moves towards the fourth component 22 and contacts the fourth component 22 as the connecting piece 33 deforms. Since the second component 12 is connected to the external circuit through the first conductive pin 13, and the fourth component 22 is connected to the external circuit through the second conductive pin 23, when the first contact 31 contacts the second component 12 and the second contact 32 contacts the fourth component 22, an electrical connection path is established between the first detection component 10 and the second detection component 20, and the first conductive pin 13 and the second conductive pin 23 are in a conductive state.

[0030] Optionally, when the connecting piece 33 is not compressed or the compressive force is insufficient to deform the movable metal contact 30, the movable metal contact 30 maintains its natural state due to its own elasticity. In its natural state, there is a gap between the first contact 31 and the second component 12, and a gap between the second contact 32 and the fourth component 22. Since the first contact 31 and the second contact 32 are fixedly connected as a single structure by the connecting piece 33, the first contact 31 and the second contact 32 move synchronously. Therefore, only when the connecting piece 33 is subjected to sufficient compressive force to deform the movable metal contact 30 will the first contact 31 and the second contact 32 synchronously contact and connect with the corresponding second component 12 and fourth component 22, establishing an electrical connection path between the first detection component 10 and the second detection component 20, making the detection results accurate and reliable.

[0031] It should be noted that the first conductive pin 13 is connected to the first component 11, and the second conductive pin 23 is connected to the third component 21. Both the first and third components have insulating layers on their surfaces. Although the insulating layers are located on the surfaces of the first and third components 11 and 21, the internal components 11 and 21 still maintain conductivity. Since the first conductive pin 13 is connected to the first component 11, the first component 11 is electrically connected to the second component 12 through its internal conductivity; similarly, the second conductive pin 23 is connected to the third component 21, and the third component 21 is electrically connected to the fourth component 22 through its internal conductivity. The insulating layers are only used to block the electrical connections between the surface of the first component 11 and the first antenna 31, and between the surface of the third component 21 and the second antenna 32; they do not affect the conductivity between the first and second components 11 and 12, or between the third and fourth components 21 and 22.

[0032] Optionally, the connection position between the first conductive pin 13 and the first detection component 10 can be adjusted according to actual needs. For example, the first conductive pin 13 can be connected to the first component 11 or the second component 12, as long as an electrical connection can be formed between the first conductive pin 13 and the second component 12. When the first conductive pin 13 is connected to the first component 11, since there is a conductive connection between the first component 11 and the second component 12, the current can be conducted to the second component 12 through the first component 11; when the first conductive pin 13 is connected to the second component 12, the second component 12 directly forms an electrical connection with the first conductive pin 13. Similarly, the second conductive pin 23 can be connected to the third component 21 or the fourth component 22, as long as an electrical connection can be formed between the second conductive pin 23 and the fourth component 22. When changing the connection positions of the first conductive pin 13 and the second conductive pin 23, the position of the insulating layer also needs to be adjusted accordingly to ensure that the surfaces of the first component 11 and the third component 21 are still provided with an insulating layer, thereby blocking the electrical connection between the first antenna 31 and the first component 11 and between the second antenna 32 and the third component 21. This ensures that under natural conditions, the first detection component 10 and the second detection component 20 will not accidentally establish an electrical connection path due to the first antenna 31 abutting against the first component 11 or the second antenna 32 abutting against the third component 21. Regardless of which component the first conductive pin 13 and the second conductive pin 23 are connected to, as long as the surfaces of the first component 11 and the third component 21 are provided with an insulating layer, the technical effect of the present invention can be achieved, and all are within the protection scope of the present invention.

[0033] The technical solution of this invention employs a first detection component 10, a second detection component 20, and a movable metal contact 30. It utilizes the positional changes of the movable metal contact 30 under compressed and natural conditions to determine whether an electrical connection is established between the first detection component 10 and the second detection component 20. When the connecting piece 33 of the movable metal contact 30 is compressed, the first contact 31 of the movable metal contact 30 connects to the second component 12, and the second contact 32 of the movable metal contact 30 connects to the fourth component 22, establishing an electrical connection between the first detection component 10 and the second detection component 20. When the connecting piece 33 is not compressed, there is a gap between the second component 12 and the first contact 31 of the movable metal contact 30, and a gap between the fourth component 22 and the second contact 32 of the movable metal contact 30, indicating that no electrical connection is established between the first detection component 10 and the second detection component 20. The terminal detection device 100 achieves the determination of the continuity of the electrical connection through a simple mechanical structure, eliminating the need for manual visual inspection, improving insertion efficiency, and its simple structure makes it easy to integrate into various slot connectors 300. In addition, the insulating layers on the surfaces of the first component 11 and the third component 21 can prevent the first contact 31 and the second contact 32 of the movable metal contact 30 from making a false connection due to accidental contact when not under pressure, thus making the detection results more reliable.

[0034] In one embodiment, the first detection component 10 is an L-shaped conductive sheet, and the first contact angle 31 of the movable metal contact 30 is disposed on the inner side of the bend of the L-shaped conductive sheet; and / or, The second detection component 20 is an L-shaped conductive sheet, and the second contact 32 of the movable metal contact 30 is located on the inside of the bend of the L-shaped conductive sheet.

[0035] Optionally, the first detection component 10 is an L-shaped conductive sheet. The L-shaped conductive sheet has a first arm and a second arm, wherein the first arm extends along the width direction of the slot connector 300, and the second arm bends and extends from one end of the first arm along the height direction of the slot connector 300, with the first arm and second arm together forming an inner bent area. A first contact 31 is disposed in the inner bent area. The first arm of the L-shaped conductive sheet is connected to the first conductive pin 13. Except for the upper surface of the first arm and the inner surface of the second arm, the remaining surfaces of the L-shaped conductive sheet are provided with an insulating layer. The upper surface of the first arm is the surface facing the movable metal contact 30, and the inner surface of the second arm is the surface facing the first contact 31. The insulating layer is disposed on the surface of the L-shaped conductive sheet, but the interior of the L-shaped conductive sheet still maintains conductivity. The insulating layer is only used to block the electrical connection between the first contact 31 and the area of ​​the L-shaped conductive sheet other than the upper surface of the first arm and the inner surface of the second arm; it does not affect the conductivity of the interior of the L-shaped conductive sheet along the first and second arms. In its uncompressed natural state, the connecting piece 33 has a gap between the first antenna 31 and the inner surface of the second arm, and the first antenna 31 does not contact the L-shaped conductive piece, thus no electrical connection is established. In the compressed state, the connecting piece 33 deforms under pressure, and the first antenna 31 moves towards the L-shaped conductive piece as the connecting piece 33 deforms. The first antenna 31 then contacts the inner surface of the second arm, establishing an electrical connection.

[0036] Optionally, the second detection component 20 and the first detection component 10 are both L-shaped conductive sheets. The working principle of the second detection component 20 is similar to that of the first detection component 10, and will not be described in detail here.

[0037] In one embodiment, the first detection component 10 is a groove-shaped conductive sheet, and the first contact angle 31 of the movable metal contact 30 is disposed inside the groove of the groove-shaped conductive sheet; and / or, The second detection component 20 is a groove-shaped conductive sheet, and the second contact 32 of the movable metal contact 30 is disposed inside the groove of the groove-shaped conductive sheet.

[0038] Optionally, the first detection component 10 is a groove-shaped conductive sheet. The groove-shaped conductive sheet has a bottom wall, a first side wall, and a second side wall, which together form a groove. A first contact 31 is disposed inside the groove. The bottom wall of the groove-shaped conductive sheet is connected to the first conductive pin 13. Except for the inner surfaces of the first and second side walls, the surface of the groove-shaped conductive sheet is provided with an insulating layer. The insulating layer is disposed on the surface of the groove-shaped conductive sheet, and the interior of the groove-shaped conductive sheet still maintains its conductivity. The insulating layer is only used to block the electrical connection between the first contact 31 and the area of ​​the groove-shaped conductive sheet other than the inner surfaces of the first and second side walls, and does not affect the conductivity along the bottom wall, first side wall, and second side wall inside the groove-shaped conductive sheet. In the natural state where the connecting piece 33 is not compressed, the first contact 31 is located inside the groove, with a gap between the first contact 31 and the inner surfaces of the first and second side walls. The first contact 31 does not contact the groove-shaped conductive sheet, and no electrical connection is established. When the connecting piece 33 is under pressure, the connecting piece 33 deforms under force, and the first antenna 31 moves towards the groove-shaped conductive piece as the connecting piece 33 deforms. The first antenna 31 contacts the inner surface of the first sidewall or the inner surface of the second sidewall to establish an electrical connection path.

[0039] Optionally, the second detection component 20 and the first detection component 10 are both groove-shaped conductive sheets. The working principle of the second detection component 20 is similar to that of the first detection component 10, and will not be described in detail here.

[0040] Optionally, the shapes of the first detection component 10 and the second detection component 20 can be different. For example, the first detection component 10 can be the aforementioned groove-shaped conductive sheet, and the second detection component 20 can be an L-shaped conductive sheet; or, the first detection component 10 can be an L-shaped conductive sheet, and the second detection component 20 can be a groove-shaped conductive sheet. The specific shapes of the first detection component 10 and the second detection component 20 can be selected according to actual needs, as long as they can cooperate with the first contact 31 and the second contact 32 respectively to complete the establishment and disconnection of electrical connection.

[0041] In one embodiment, the insulating layer is any one of a polyimide insulating layer, a polyester insulating layer, an epoxy resin insulating layer, a silicone insulating layer, or a ceramic insulating layer.

[0042] Optionally, the insulating layer on the surface of the first component 11 is an insulating coating applied to the surface of the first component 11, and the insulating coating is made of any one of polyimide, polyester, epoxy resin, silicone or ceramic material. The insulating layer on the surface of the third component 21 is configured in the same way as the first component 11.

[0043] Optionally, the insulating layer on the surface of the first component 11 is an insulating sleeve fitted around the outer periphery of the first component 11, and the insulating layer on the surface of the third component 21 is an insulating sleeve fitted around the outer periphery of the third component 21.

[0044] Optionally, the insulating layer on the surface of the first component 11 is an insulating plastic layer that is coated on the surface of the first component 11 by injection molding, and the insulating layer on the surface of the third component 21 is an insulating plastic layer that is coated on the surface of the third component 21 by injection molding.

[0045] It should be noted that, regardless of the insulation method used, as long as an insulating layer can be formed on the surface of the first component 11 to block the electrical connection between the first antenna 31 and the first component 11, and an insulating layer can be formed on the surface of the third component 21 to block the electrical connection between the second antenna 32 and the third component 21, it is acceptable.

[0046] like Figure 8 The present invention also provides a terminal detection assembly 200, comprising: a detection circuit 40 and a terminal detection device 100 as described above; The detection circuit 40 is connected to the first conductive pin 13 and the second conductive pin 23 of the terminal detection device 100, respectively. The detection circuit 40 is used to determine that the terminal detection device 100 is pressed by the pin when an electrical connection path is detected between the first conductive pin 13 and the second conductive pin 23. The detection circuit 40 is also used to determine that the terminal detection device 100 is not squeezed by the pin if no electrical connection path is established between the first conductive pin 13 and the second conductive pin 23.

[0047] Optionally, the detection circuit 40 is used to detect the continuity between the first conductive pin 13 and the second conductive pin 23. When an electrical connection is detected between the first conductive pin 13 and the second conductive pin 23, the detection circuit 40 determines that the terminal detection device 100 is being squeezed by a pin. Specifically, when the connecting piece 33 is squeezed, the connecting piece 33 deforms under force, the first contact 31 contacts the second component 12, and the second contact 32 contacts the fourth component 22, thus establishing an electrical connection between the first conductive pin 13 and the second conductive pin 23. After detecting this electrical connection, the detection circuit 40 determines that the terminal detection device 100 is being squeezed by a pin and determines that there is an abnormality in the terminal within the slot connector 300.

[0048] Optionally, when it is detected that no electrical connection is established between the first conductive pin 13 and the second conductive pin 23, the detection circuit 40 determines that the terminal detection device 100 is not being squeezed by the pins. Specifically, when the connecting piece 33 is not being squeezed, the movable metal contact 30 is in its natural state, there is a gap between the first contact 31 and the second component 12, a gap between the second contact 32 and the fourth component 22, and the first conductive pin 13 and the second conductive pin 23 are in an open circuit state. Since the detection circuit 40 does not detect an electrical connection, it determines that the terminal detection device 100 is not being squeezed by the pins and determines that the terminals within the slot connector 300 are in a normal state.

[0049] The terminal detection assembly 200 includes a detection circuit 40 and a terminal detection device 100. The specific structure of the terminal detection device 100 is as described in the above embodiments. Since the terminal detection assembly 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] like Figure 9 As shown, in one embodiment, the first conductive pin 13 of the terminal detection device 100 is grounded, and the detection circuit 40 includes: Resistor R1, power supply terminal 41, and control circuit 42; The first end of resistor R1 is connected to power supply terminal 41, and the second end of resistor R1 is connected to control circuit 42 and second conductive pin 23 respectively. If no electrical connection is established between the first conductive pin 13 and the second conductive pin 23, the second conductive pin 23 is connected to the power supply terminal 41 through the resistor R1, and the control circuit 42 detects that the second conductive pin 23 is in the first level state. When an electrical connection is established between the first conductive pin 13 and the second conductive pin 23, the second conductive pin 23 is grounded through the first conductive pin 13. The control circuit 42 detects that the second conductive pin 23 is in a second level state, and the control circuit 42 generates an alarm signal based on the second level state.

[0051] Optionally, the first conductive pin 13 of the terminal detection device 100 is grounded, and the detection circuit 40 includes a resistor R1, a power supply terminal 41, and a control circuit 42. The first end of the resistor R1 is connected to the power supply terminal 41, and the second end of the resistor R1 is connected to the control circuit 42 and the second conductive pin 23. The power supply terminal 41 provides a voltage signal, such as a 3.3V or 5V DC voltage. The resistor R1 acts as a pull-up resistor, maintaining the voltage level of the second conductive pin 23 at the high level corresponding to the voltage provided by the power supply terminal 41 when the second conductive pin 23 is not electrically connected to the first conductive pin 13. Simultaneously, it limits the current in the circuit when the first conductive pin 13 and the second conductive pin 23 are electrically connected, thus protecting the circuit.

[0052] Optionally, if no electrical connection is established between the first conductive pin 13 and the second conductive pin 23, the second conductive pin 23 is connected to the power supply terminal 41 through a resistor R1, and the control circuit 42 detects that the second conductive pin 23 is in a first level state. Since there is an open circuit between the first conductive pin 13 and the second conductive pin 23, the second conductive pin 23 is pulled up to the first level state (e.g., a high level state) by the power supply terminal 41 through the resistor R1. After the control circuit 42 detects the high level state, it determines that the terminal detection device 100 is not squeezed by the pin, and the terminal in the slot connector 300 is in a normal state.

[0053] Optionally, when an electrical connection is established between the first conductive pin 13 and the second conductive pin 23, the second conductive pin 23 is grounded through the first conductive pin 13. The control circuit 42 detects that the second conductive pin 23 is in a second level state and generates an alarm signal based on the second level state. Since the first conductive pin 13 is grounded, when an electrical connection is established between the first conductive pin 13 and the second conductive pin 23, the second conductive pin 23 is pulled to ground level through the electrical connection, i.e., the second level state (e.g., a low level state). After the control circuit 42 detects the low level state, it determines that the terminal detection device 100 is being squeezed by the pin, and that there is abnormal deformation of the terminal in the slot connector 300. It then generates an alarm signal based on the low level state. The alarm signal can be used to notify the system or maintenance personnel to handle the situation.

[0054] Optionally, the control circuit 42 can be implemented using a main controller, such as an MCU (Micro Controller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or a SOC (System On Chip).

[0055] like Figure 8 and Figure 10 The present invention also provides a slot connector 300, including a terminal detection device 100 as described in any of the above claims; The slot connector 300 includes a slot plastic 50 and a connection terminal 60 disposed within the slot connector 300, and the terminal detection device 100 is disposed relative to the slot connector 300. When the pin is inserted into the slot plastic 50, the pin and the connecting terminal 60 establish an electrical connection path and the pin presses against the terminal detection device 100, so that the terminal detection device 100 establishes an electrical connection path. When the pin is not inserted into the slot plastic 50, no electrical connection is established between the pin and the connecting terminal 60, and the pin does not press against the terminal detection device 100, so that the terminal detection device 100 does not establish an electrical connection.

[0056] Optionally, the slot connector 300 includes a terminal detection device 100 as described in any of the above embodiments. The slot connector 300 is provided with slot plastic 50 and connection terminals 60 disposed within the slot connector 300. The terminal detection device 100 is disposed relative to the slot connector 300. Specifically, the terminal detection device 100 is disposed at the bottom of the slot connector 300.

[0057] Optionally, when the pin is inserted into the slot plastic 50, the pin establishes an electrical connection path with the connecting terminal 60, and at the same time, the pin presses against the terminal detection device 100 to establish an electrical connection path. Specifically, when an external board is inserted into the slot plastic 50, the pins (i.e., gold fingers) on the board contact the connecting terminal 60 inside the slot connector 300 to establish an electrical connection path; at the same time, if the connecting terminal 60 is abnormally deformed, the deformed connecting terminal 60 or the pin will press against the connecting piece 33 of the movable metal contact 30, causing the movable metal contact 30 to deform. The first contact 31 contacts and connects with the second component 12, and the second contact 32 contacts and connects with the fourth component 22. An electrical connection path is established between the first detection component 10 and the second detection component 20, and the first conductive pin 13 and the second conductive pin 23 switch to a closed state, thereby triggering the detection circuit 40 to generate an alarm signal.

[0058] Optionally, when the pin is not inserted into the slot plastic 50, no electrical connection is established between the pin and the connecting terminal 60, and the pin does not press against the terminal detection device 100, so that the terminal detection device 100 does not establish an electrical connection. Specifically, when the external board is not inserted into the slot plastic 50, there is no contact between the connecting terminal 60 and the pin, and no electrical connection is established; at the same time, the connecting terminal 60 is not pressed, the connecting piece 33 of the movable metal contact 30 is not pressed, the movable metal contact 30 remains in its natural state, a gap is maintained between the first contact 31 and the second component 12, a gap is maintained between the second contact 32 and the fourth component 22, the first conductive pin 13 and the second conductive pin 23 are in an open circuit state, and the detection circuit 40 does not generate an alarm signal.

[0059] Optionally, the slot connector 300 can be any one of a PCIe slot, Gen Z slot, MCIO slot, Slim-SAS slot, or DDR memory slot. It can be understood that the terminal detection device 100 can be applied to various types of slot connectors 300, as long as the slot connector 300 has connection terminals 60 and sufficient space for installing the terminal detection device 100; no specific limitation is made here.

Since the slot connector 300 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
