Description

Technical Field

[0001] The utility model relates to the field of hot plugging, in particular to an in-position signal connector supporting hot plugging, a board card, and an electronic device. Background Art

[0002] In server systems, the continuous operation of equipment is crucial, and any downtime may bring huge losses. Hot-swap technology can meet the high reliability, high availability and flexibility requirements of server systems, especially playing a huge role in the replacement and upgrade of components without interrupting system power supply and normal operation.

[0003] With the development of server systems, the introduction of the PCIE bus into the system bus has initially met the needs of hot plugging. Hot plugging technology has been widely used in servers, workstations, and various electronic devices, especially in disk mirroring systems, where it has become a standard feature and has greatly improved the flexibility of the system. Currently, hot plug connectors implement hot plugging functionality through the design of a long or short PIN for the in-position signal. This is especially true in hardware interfaces that require high reliability and stability, such as the PCIe interface. The long or short PIN design ensures that the system can accurately detect the device status when the device is plugged in and out, and controls the power-on and power-off timing, thereby improving the security and reliability of the hardware interface.

[0004] However, the long and short PIN design currently used in connectors has defects. During the plugging and unplugging process, uneven force may cause oblique insertion. Once oblique insertion occurs, the PRSNT# signal will take precedence over other signals to complete the connection, resulting in the risk of signal interference, signal attenuation, and even device damage during the subsequent connection process due to power. Similarly, the unplugging process may also cause timing and data loss or even hardware damage due to direct disconnection of power. Summary of the Invention

[0005] Aiming at the problem that data loss and equipment damage may occur due to the uneven force during hot plugging and the occurrence of oblique plugging, the long and short PIN solutions currently used in hot plugging, the utility model provides an in-position signal connector that supports hot plugging.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is to provide an in-position signal connector supporting hot plugging, comprising a connector body;

[0007] The connector body is provided with an in-position signal pin;

[0008] The presence signal pin has a snap-fit ​​structure and is located on the outside of the connector body. This ensures that during the connector connection process, the snap-fit ​​presence signal pin is connected last, and during the connector disconnection process, the snap-fit ​​presence signal pin is disconnected first. In this solution, by designing the snap-fit ​​presence signal pin and placing it on the outside of the connector body, the snap-fit ​​presence signal pin is connected last during the connector connection process and disconnected first during the disconnection process. This avoids the problem of skew insertion caused by uneven force during the plug-in and unplug process, thereby reducing the risk of signal interference, signal attenuation, and equipment damage.

[0009] Preferably, the connector body includes a first connector and a second connector;

[0010] The first connector and the second connector each include a side surface and a plug-in surface;

[0011] Functional pins are provided in the plugging surfaces of the first connector and the second connector, and the functional pins of the first connector are plugged into the functional pins of the second connector;

In this preferred embodiment, the connector body is divided into a first connector and a second connector, and mateable presence signal pins with snap-fit ​​structures are provided on the sides of both connectors. This improves the stability and reliability of the connectors. Furthermore, the functional pins are located within the mating surface, ensuring the normal transmission of functional signals.

[0015] Preferably, the first connector is provided on a board, and the functional pins of the first connector are pin structures;

In this preferred embodiment, by configuring the functional pins of the first and second connectors in a pin-and-slot configuration, the connectors are more suitable for connecting the board with external devices, thereby improving the versatility and practicality of the connectors.

[0017] Preferably, the number of the first presence signal pin ends is two, including a first A+ presence signal pin and a first B+ presence signal pin;

[0018] The first A+ in-place signal pin is oppositely arranged with the first B+ in-place signal pin on both sides of the first connector;

[0019] The number of the second in-place signal pin ends is two, including a second A- in-place signal pin and a second B- in-place signal pin;

[0020] The second A- in-place signal pin is oppositely arranged with the second B- in-place signal pin on both sides of the second connector;

[0021] The first A+ in-place signal pin and the second A- in-place signal pin are in a matching buckle structure, and the first B+ in-place signal pin and the second B- in-place signal pin are in a matching buckle structure. In the preferred embodiment, by arranging two pairs of oppositely arranged in-place signal pins in the buckle structure, the stability and reliability of the connector are enhanced, and the convenience and accuracy of the plugging operation are also improved.

[0025] The hot plug controller is further connected with a functional pin of the first connector. In the preferred embodiment, by arranging the hot plug controller on the board card and connecting it with the in-place signal pin, real-time monitoring and control of the plugging operation are realized, and the connection of the pull-up resistor and the power supply also ensures the stability and reliability of the signal transmission.

In the preferred embodiment, by the specific arrangement of the male buckle structure and the female buckle structure, the buckle structure is more stable and reliable, and the plugging operation is also simplified, improving the user experience.

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

[0042] Example 1

[0043] like Figure 1 As shown, a hot-swappable in-position signal connector includes a connector body 1;

[0044] The connector body 1 is provided with a position signal pin 2;

[0045] The in-position signal pin 2 is in a snap-fit ​​structure and is arranged on the outside of the connector body 1, so that during the connection process of the connector body 1, the in-position signal pin 2 in a snap-fit ​​structure is connected last, and during the disconnection process of the connector body 1, the in-position signal pin 2 in a snap-fit ​​structure is disconnected first.

[0046] This embodiment uses a snap-fit ​​structure to achieve both fastening and release of the connection, resulting in a connector with excellent plug-in and unplugging performance and reusability. By designing the in-position signal pin in a snap-fit ​​structure and positioning it on the outside of the connector body, this ensures that the snap-fit ​​signal pin is connected last during the connector connection process and disconnected first during the disconnection process. This avoids the problem of skewed insertion caused by uneven force during the plug-in and unplugging process, thereby reducing the risk of signal interference, signal attenuation, and device damage. Furthermore, the snap-fit ​​structure ensures a fool-proof design. Since only plugs with a specific snap-fit ​​can be inserted into the corresponding receptacle, this prevents the mis-insertion of devices due to interface mismatches.

[0072] The accommodating space matches the male buckle structure, and the end of the bent portion is provided with a barb portion matching the protrusion;

[0073] It should be noted that the female buckle structure with a downward-inclined protrusion and a receiving space matching the barb portion further enhances the stability and reliability of the snap-on structure.
