Description

Technical Field

[0001] This utility model relates to the field of electronic device interface technology, and more specifically, to a DVI-24+1 pin connector with hot-swappable function. Background Technology

[0002] The DVI-24+1 pin connector consists of several key components, including mechanical structure, electrical interface, and shielding design. The housing and mechanical structure include a metal shielding shell, fixing screws, and plastic insulator. The electrical interface includes digital signal pins, analog signal pins, and hot-plug detection pins. By delaying power supply, after detecting the HPD signal, the TMDS signal is activated after a delay of 100-500ms to avoid current surges during insertion and removal. At the same time, a TVS diode (such as PESD5V0S1BT) is added to the HPD pin to prevent electrostatic damage. A low-impedance grounding path is used to ensure that the DVI metal housing is directly connected to the device ground, reducing common-mode noise during hot-plugging, thus realizing the hot-plug function.

[0003] When the DVI-24+1 pin connector is idle, the electrical interface with 24 digital pins and 1 analog pin is fully exposed. Since the DVI interface needs to maintain plug-and-play compatibility, it cannot be completely sealed like a waterproof USB interface, which makes it easy for dust to enter. When dust enters the TMDS (Digital Signal) pins, it can cause poor contact, signal interference leading to flickering and black screen, and reduce the service life. Utility Model Content

[0004] The purpose of this invention is to provide a DVI-24+1 pin connector with hot-swappable function to solve the problems mentioned in the background art.

[0005] When the electrical interface is fully exposed, dust can easily get in. When dust gets into the TMDS (Digital Signal) pins, it can cause poor contact, signal interference leading to flickering and black screen, and also reduce the lifespan of the device.

[0006] To achieve the above objectives, this utility model provides a DVI-24+1 pin connector with hot-swappable functionality, comprising a connector body, with screws threaded through the inner walls of both sides of the connector body, an electrical interface end fixedly connected to the end of the connector body, and an auxiliary protective mechanism provided outside the electrical interface end. The auxiliary protective mechanism is used to protect the electrical interface end when it is not plugged in. The auxiliary protective mechanism includes a protective cover sleeved on the outside of the electrical interface end, with a fixed frame fixedly connected to the opening end of the protective cover near the screws. A support plate is fixedly connected to the side wall of the connector body at the electrical interface end, and two legs are symmetrically fixedly connected to the top of the support plate. A clamping plate is hinged between the side walls of the two legs and above the surface of the support plate. A torsion spring is sleeved inside the hinge point between the clamping plate and the two legs. Several support plates, legs, and clamping plates are symmetrically and evenly arranged on the side wall of the connector body with the electrical interface end as the axis.

[0007] Using a protective cover can protect the electrical interface from dust and water when it is not in use. At the same time, if the electrical interface is accidentally dropped to the ground, the protective cover can cushion the impact and prevent further damage to the electrical interface.

[0008] As a further improvement to this technical solution, several rectangular grooves are provided on the surface of the multiple clamping plates away from the electrical interface end, and the ends of the multiple support plates and clamping plates are all arc-shaped.

[0009] The rectangular groove increases the surface friction of the clamping plate, making it easier to press with your fingertips. The curved design facilitates the insertion and removal of the fixing frame.

[0010] As a further improvement to this technical solution, protective caps are fixedly connected to both outer walls of the protective cover. Each of the two protective caps is inserted into one end of two fixing screws near the electrical interface. Several support rods are evenly fixedly connected to the open ends of the two protective caps. A positioning ring is provided on one side of the open end of each of the two protective caps. The two positioning rings are fixedly connected to the multiple support rods respectively.

[0011] Using a protective cap can prevent water droplets and dust from affecting the fixing screws. At the same time, before the protective cover is put on, the positioning ring is used to initially put the fixing screw near the electrical interface end, thereby playing a positioning role and making it easy for the protective cover to be accurately put on the outside of the electrical interface end.

[0012] As a further improvement to this technical solution, a rectangular ring is fixedly connected to the outer wall of the electrical interface end near the connector body. An installation groove is provided on the inner wall of the rectangular ring, and a sealing ring is fixedly connected inside the installation groove.

[0013] Under the pressure, the gap between the electrical interface end located at one end of the rectangular ring and the port of the equipment is sealed, thus achieving the function of sealing and dust prevention.

[0014] As a further improvement to this technical solution, water guide plates are fixedly connected to the top and bottom of the protective cover, and the surfaces of both water guide plates are designed with an angled surface.

[0015] The inclined water guide plate allows water droplets to quickly slide off the surface of the protective cover, ensuring the surface of the protective cover is dry and thus improving the protection effect on the electrical interface.

[0016] As a further improvement to this technical solution, an elastic rope is fixedly connected to the side wall of the fixed frame, and the end of the elastic rope away from the fixed frame is fixedly connected to the outer wall of the connector body.

[0017] An elastic cord is incorporated to prevent the protective cover from falling off when removed, ensuring it remains connected to the connector body, reducing the probability of loss, and facilitating future use.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In this hot-swappable DVI-24+1 pin connector, an auxiliary protective mechanism is incorporated. Under the return of the torsion spring, the clamping plate resets and, together with the support plate, presses against the fixing frame, thus firmly securing the protective cover to the outside of the electrical interface. The protective cover protects the electrical interface from dust and water during idle periods, preventing issues such as poor contact, signal interference causing flickering, and black screens. Furthermore, if the electrical interface is accidentally dropped, the protective cover acts as a buffer, preventing further damage and extending the lifespan of the electrical interface.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-5As shown, this embodiment provides a DVI-24+1 pin connector with hot-swappable functionality, including a connector body 1. Two fixing screws 2 are threaded through the inner walls of both sides of the connector body 1. An electrical interface terminal 3 is fixedly connected to the end of the connector body 1. The hot-swappable connector body 1 is inserted into the device port via the electrical interface terminal 3, and then threadedly connected to the device port using the two fixing screws 2 to complete the installation. An auxiliary protection mechanism 4 is provided on the outside of the electrical interface terminal 3 to protect the electrical interface terminal 3 when it is not inserted. The connector body 1 includes a protective cover 41 fitted outside the electrical interface end 3. A fixing frame 42 is fixedly connected to the opening end of the protective cover 41 near the fixing screw 2. A support plate 43 is fixedly connected to the side wall of one end of the connector body 1 located at the electrical interface end 3. Two legs 44 are symmetrically fixedly connected to the top of the support plate 43. A clamping plate 45 is hinged between the side walls of the two legs 44 and above the surface of the support plate 43. Torsion springs are fitted inside the hinge joints between the clamping plate 45 and the two legs 44. Several support plates 43, legs 44 and clamping plates 45 are symmetrically and evenly arranged on the side wall of the connector body 1 with the electrical interface end 3 as the axis.

[0030] When the connector body 1 is idle, the protective cover 41 is fitted over the electrical interface terminal 3, allowing the frame of the fixing frame 42 to be inserted into the gap between the clamping plate 45 and the support plate 43. Since the clamping plate 45 is hinged to the two legs 44, when the clamping plate 45 is pushed, it flips on the surface of the support plate 43 and simultaneously compresses the torsion spring. As the fixing frame 42 is inserted into place, the clamping plate 45 returns to its original position under the rebound of the torsion spring and presses the fixing frame 42 with the support plate 43, thereby firmly fixing the protective cover 41 to the outside of the electrical interface terminal 3. The protective cover 41 can protect the electrical interface terminal 3 from dust and water during idle periods, preventing poor contact, signal interference causing flickering and black screen phenomena. At the same time, when the electrical interface terminal 3 is accidentally dropped to the ground, the protective cover 41 can act as a buffer, preventing greater damage to the electrical interface terminal 3, thereby extending the service life of the electrical interface terminal 3.

[0031] Several rectangular grooves 51 are provided on the surface of the clamping plates 45 away from the electrical interface end 3. When the protective cover 41 needs to be removed from the outside of the electrical interface end 3, it can be pulled out by force. If the clamping is too tight, it is necessary to manually press the surface of the clamping plate 45 away from the fixed frame 42. The rectangular grooves 51 can increase the surface friction of the clamping plate 45, making it easier to press with fingertips. The ends of the multiple support plates 43 and the clamping plates 45 are all arc-shaped. The arc design facilitates the insertion and removal of the fixed frame 42.

[0032] Protective caps 52 are fixedly connected to both outer walls of the protective cover 41. Each protective cap 52 is inserted into the end of the two fixing screws 2 near the electrical interface end 3. Several support rods 53 are evenly fixedly connected to the open ends of the two protective caps 52. A positioning ring 54 is provided on one side of the open end of each of the two protective caps 52. The two positioning rings 54 are fixedly connected to the multiple support rods 53 respectively. The protective caps 52 are installed synchronously with the protective cover 41, so that the protective caps 52 can protect the end of the fixing screws 2 located at the electrical interface end 3, preventing water droplets and dust from affecting the fixing screws 2. At the same time, before the protective cover 41 is put on, the positioning rings 54 are used to preliminarily put on the end of the fixing screws 2 near the electrical interface end 3, thereby playing a positioning role, so that the protective cover 41 can be accurately put on the outside of the electrical interface end 3.

[0033] A rectangular ring 61 is fixedly connected to the outer wall of the electrical interface terminal 3 near the connector body 1. An installation groove 62 is provided on the inner wall of the rectangular ring 61, and a sealing ring 63 is fixedly connected inside the installation groove 62. When the connector body 1 connects the electrical interface terminal 3 to the device port using the fixing screw 2, after the electrical interface terminal 3 is fully inserted, the sealing ring 63 will fit against the outer wall of the device port. Under the pressure, the gap between the electrical interface terminal 3 at one end of the rectangular ring 61 and the device port is sealed, thus providing a dustproof seal. Water guide plates 11 are fixedly connected to the top and bottom of the protective cover 41. Both water guide plates 11 have a beveled surface design. When the connector body 1… When not in use, the protective cover 41 is fitted over the outside of the electrical interface end 3. The inclined water guide plate 11 allows water droplets to quickly slide off the surface of the protective cover 41, ensuring that the surface of the protective cover 41 is dry, thereby improving the protective effect on the electrical interface end 3. An elastic rope 71 is fixedly connected to the side wall of the fixing frame 42. The end of the elastic rope 71 away from the fixing frame 42 is fixedly connected to the outer wall of the connector body 1. When the connector body 1 needs to be used, the protective cover 41 is removed from the outside of the electrical interface end 3. By setting the elastic rope 71, the protective cover 41 will not fall off when it is removed and will always be connected to the connector body 1, reducing the probability of loss and facilitating the next use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
