Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a DVI connector with an auxiliary pull-out function. Background Technology

[0002] With the rapid development of information technology, the demand for data transmission between display devices and video sources is increasing daily. To meet this demand, various digital video interface standards have emerged. Among them, the Digital Video Interface (DVI) is an important display interface standard that occupies a significant position in the field of high-definition video transmission. Since its introduction, DVI cables have undergone technological evolution from single-link to dual-link. Dual-link DVI cables can provide higher data transmission rates, thereby supporting higher resolution and refresh rate display requirements, making DVI cables widely used in personal computers, workstations, high-end monitors, and projectors.

[0003] Despite the excellent performance of DVI cables in video transmission, users often face operational challenges in practical use, especially in office environments or home entertainment systems. Particularly when disconnecting the DVI cable, the DVI ports on most monitors and computer hosts are located on the back of the device, where space is often very limited. For example, the back panel of the monitor and the cramped space behind the computer host cause significant inconvenience for users.

[0004] When unplugging the DVI cable, the user must first loosen or unscrew the screws securing the connector on both sides before pulling the cable out of the socket. This requires precise manual operation within a very limited space, increasing the difficulty and potentially causing the user to apply excessive force to overcome the space constraints. This could damage the DVI cable, and the user's hand may also hit the back panel of the workspace after unplugging the cable, resulting in injury.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a DVI connector cable with an auxiliary pull-out function, comprising a connector cable, connectors at both ends of the connector cable, a top plate on one side of the connectors, and an interface on the top plate. The connectors have a built-in circuit board electrically connected to the connector cable, and the interface passes through the top plate and is electrically connected to the circuit board.

[0008] Each of the four corners of the top plate near the joint is provided with a sleeve post, and a knob is provided on the side of the sleeve post away from the top plate. The knob is connected to a bolt, and the bolt passes through the sleeve post and the top plate.

[0009] Fixed posts are provided at the four corners of the top plate away from the interface. The fixed posts have movable grooves on the side facing the top plate. An ejector rod is provided in the movable groove. Through holes for the ejector rod to extend are provided at the four corners of the top plate. An elastic element is provided between the ejector rod and the inner wall of the movable groove. The elastic element uses elastic force to push the ejector rod out of the through hole.

[0010] As a further embodiment of this utility model: the movable groove is provided with a movable plate, and the two sides of the movable plate are respectively connected to the ejector rod and the elastic element;

[0011] Wherein, the diameter of the perforation is smaller than that of the movable groove, and the diameter of the movable plate is larger than that of the perforation.

[0012] As a further embodiment of this utility model: a guide hole is provided on the inner wall of the movable groove on the side opposite to the movable plate, and a guide rod is slidably connected in the guide hole, and the guide rod is connected to the movable plate.

[0013] As a further embodiment of this utility model: the elastic element is a spring, and the elastic element is sleeved outside the guide rod.

[0014] As a further embodiment of this utility model: the top plate is provided with two ejector plates at the end away from the joint, the two ejector plates are respectively close to the two sides of the top plate in the length direction, and the two adjacent ejector rods in the length direction are respectively connected to the two sides of the corresponding ejector plate.

[0015] As a further embodiment of this utility model: the top plate has two storage slots on one side near the interface, which correspond to the two top plates, and the storage slots are connected to the perforations.

[0016] As a further embodiment of this utility model: the surface of the connector has anti-slip texture.

[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: When it is necessary to pull the interface of the connector out of the socket, the bolt is first disengaged from the screw hole at the socket end by turning. Then, at the same time as the user pulls out the connector, the elastic element inside the movable groove uses elastic force to push the ejector rod, which pushes the ejector plate to apply a pushing force to the bottom plate at the socket end, thereby generating a reaction force. This causes the connector to be subjected to a pushing force away from the socket, thereby reducing the force required for the interface to separate from the socket. By reducing the force required for the user to pull out the connector, the user is assisted in pulling the interface of the connector out of the socket, avoiding the risk of equipment damage or hand injury caused by excessive force.

[0018] While the interface is inserted into the socket, the ejector plate is pushed back into the storage slot, and the ejector rod presses against the elastic element inside the movable slot. After the interface is inserted into the through hole, the knob is turned to screw the bolt into the screw hole at the socket, so as to form a fixed relationship between the interface and the socket, and avoid the interface from falling out of the socket during daily use due to the influence of the elastic element.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-3A DVI connector cable with an auxiliary pull-out function includes a connector cable 1, connectors 2 at both ends of the connector cable 1, a top plate 3 on one side of the connector 2, and an interface 4 on the top plate 3. The connector 2 has a circuit board that is electrically connected to the connector cable 1, and the interface 4 passes through the top plate 3 and is electrically connected to the circuit board to enable the normal connection and use of the DVI connector cable.

[0028] Each of the four corners of the top plate 3 near the joint 2 is provided with a sleeve post 16. A knob 17 is provided on the side of the sleeve post 16 away from the top plate 3. The knob 17 is connected to a bolt 18. The bolt 18 passes through the sleeve post 16 and the top plate 3.

[0029] Fixed posts 5 are provided at the four corners of the top plate 3 on the side away from the interface 4. Movable grooves 6 are opened on the side of the fixed posts 5 facing the top plate 3. Ejector rods 7 are provided in the movable grooves 6. Through holes 8 are opened at the four corners of the top plate 3 for the ejector rods 7 to extend out. Elastic members 9 are provided between the ejector rods 7 and the inner wall of the movable grooves 6. The elastic members 9 use elastic force to push the ejector rods 7 out of the through holes 8.

[0030] Specifically, when it is necessary to pull the interface 4 of connector 2 out of the socket, first turn the knob 17 to turn the bolt 18 out of the screw hole at the socket end of the equipment and into the sleeve 16. At this time, the fixed relationship between the interface 4 and the socket formed by the bolt 18 is released. Then, while the user applies the force to pull out the connector 2, the elastic element 9 inside the movable groove 6 uses the elastic force to push the ejector rod 7, so that the ejector rod 7 passes through the through hole 8 of the top plate 3 and applies a pushing force to the bottom plate at the socket, thereby generating a reaction force, so that the connector 2 is subjected to a pushing force away from the socket, thereby reducing the force required for the interface 4 to separate from the socket. By reducing the force required for the user to pull out, the user is assisted in pulling the interface 4 of connector 2 out of the socket, avoiding the risk of equipment damage or hand injury caused by excessive force.

[0031] When it is necessary to insert the interface 4 into the socket, align the interface 4 with the device socket and insert it. At the same time, the ejector rod 7 is pushed back into the through hole 8 and squeezes the elastic element 9 inside the movable groove 6. After the interface 4 is inserted into the through hole, turn the knob 17 to screw the bolt 18 into the screw hole at the socket to form a fixed relationship between the interface 4 and the socket, so as to avoid the interface 4 from falling out of the socket during daily use due to the influence of the elastic element 9.

[0032] Preferably, the movable groove 6 is provided with a movable plate 10, and the two sides of the movable plate 10 are respectively connected to the ejector rod 7 and the elastic element 9;

[0033] Among them, the diameter of the perforation 8 is smaller than that of the movable groove 6, and the diameter of the movable plate 10 is larger than that of the perforation 8.

[0034] By adding a movable plate 10 inside the movable groove 6 to receive the thrust of the elastic element 9, the movable plate 10 will be restricted by the top plate 3 when pushing the ejector rod 7 and moving to the opening of the movable groove 6. The diameter of the through hole 8 is smaller than that of the movable groove 6, while the diameter of the movable plate 10 is larger than that of the through hole 8, so as to prevent the ejector rod 7 from disengaging from the movable groove 6 and causing the ejector rod 7 to be unable to retract back into the movable groove 6.

[0035] Meanwhile, the movable plate 10 is restricted by the top plate 3, which can prevent the movable plate 10 from detaching from the movable groove 6, so that the elastic element 9 does not need to be fixedly connected and can be directly placed between the movable plate 10 and the inner wall of the movable groove 6, which facilitates assembly.

[0036] More preferably, a guide hole 11 is provided on the inner wall of the movable groove 6 on the side opposite to the movable plate 10, and a guide rod 12 is slidably connected in the guide hole 11, and the guide rod 12 is connected to the movable plate 10.

[0037] By connecting the guide rod 12, which is slidably connected within the guide hole 11, to the movable plate 10, it is ensured that the movable plate 10 and the ejector rod 7 move in a straight line under the push of the elastic element 9, preventing deviation or jamming. This helps improve the reliability and service life of the device.

[0038] Furthermore, the elastic element 9 is a spring, and the elastic element 9 is sleeved outside the guide rod 12. The use of a spring for the elastic element 9 sleeved outside the guide rod 12 can ensure that the elastic element 9 remains straight during the extension and retraction movement, utilizing the transmission of thrust.

[0039] Furthermore, two ejector plates 13 are provided at the end of the top plate 3 away from the joint 2. The two ejector plates 13 are respectively close to the two sides of the top plate 3 in the length direction, and the two adjacent ejector rods 7 in the length direction are respectively connected to the two sides of the corresponding ejector plate 13.

[0040] Specifically, by setting two ejector plates 13, and then using two ejector rods 7 to connect and push one ejector plate 13, the thrust on the bottom plate at the equipment socket end is made more uniform, so that the reaction thrust on the connector 2 is greater.

[0041] Among them, the top plate 3 has two storage slots 14 on one side near the interface 4, which correspond to the two top plates 13, and the storage slots 14 are connected to the through holes 8.

[0042] Specifically, the retracted ejector plate 13 is stored in the storage slot 14, thereby preventing the interface 4 from being obstructed by the ejector plate 13 when it is plugged into the socket.

[0043] The connector 2 has anti-slip texture 15 on its surface. When the user inserts or pulls out the interface 4, the anti-slip texture 15 on the connector 2 allows the user to apply force more easily and makes insertion and removal easier.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
