Description

Technical Field

[0001] The utility model relates to the technical field of connecting wires, in particular to an anti-interference VGA connecting wire capable of preventing pin bending. Background Art

[0002] VGA cable is a common video transmission cable, mainly used for video signal transmission between computers and monitors, projectors or other display devices. It includes the use of HDMI connector to connect with VGA cable to form a VGA cable that can convert high-definition video HDMI digital signal into VGA analog signal, which is suitable for all devices with standard HDMI output interface.

[0003] The interface and socket of the VGA cable are designed in a specific shape, and it is usually not easy to insert it upside down. However, in real life, when people insert the interface of the VGA cable into the socket, the sockets are located on the back of the computer host and the monitor, which limits the operator's field of vision. Therefore, it is easy for the interface of the VGA cable to be in the wrong direction. Without knowing that the interface of the VGA cable is in the wrong direction, the operator will continue to push the interface of the VGA cable toward the socket with force. At this time, the interface of the VGA cable is easy to slide on the socket to the back panel of the computer component or the display screen. During the sliding process, the pins inside the interface of the VGA cable are likely to collide with the corners of the socket, causing the pins to bend, making the interface of the VGA cable unable to be used normally.

[0004] In addition, the interface of the VGA cable transmits analog signals, which means that image distortion or color deviation may occur during long-distance transmission or when the signal quality is poor. However, the existing VGA cable signal anti-interference performance is poor and is easily interfered by electromagnetic waves from external electronic devices, which often affects the transmission quality of the VGA cable. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the problem that the operator cannot find out when the plug is in the wrong direction, causing the pins to collide and bend; and the VGA connection line has poor anti-interference performance and is easily interfered by electromagnetic waves from external electronic equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-interference VGA connecting cable that prevents pin bending, comprising a VGA connecting cable, wherein two ends of the VGA connecting cable are respectively connected to an HDMI interface and a plug, the plug is provided with a VGA interface, handles are provided on both sides of the plug, the handles are connected to fixing bolts that pass through the plug, positioning cylinders fixedly connected to the plug are provided on both sides of the VGA interface, a sliding cylinder is provided on the positioning cylinder, and the positioning cylinder and the sliding cylinder can wrap a nut on the VGA socket, and the fixing bolt is located inside the positioning cylinder; the VGA connecting cable is provided with a transmission line, an inner electromagnetic wave absorption layer, an electromagnetic wave shielding layer, an outer electromagnetic wave absorption layer and a plastic outer layer in sequence from the inside to the outside.

[0007] As a further solution of the utility model: a sliding groove is provided on the positioning cylinder, and the sliding groove and the positioning cylinder are both cylindrical, and the sliding cylinder is slidably connected to the sliding groove.

[0008] As a further solution of the utility model: multiple rows of springs are circumferentially arranged on the sliding cylinder, the vertical position of the outermost portion of the spring is greater than the vertical position of the outermost inner wall of the sliding groove, and the spring is made of rubber material.

[0009] As a further solution of the utility model: the positioning cylinder and the sliding cylinder are both made of high-hardness plastic material.

[0010] As a further solution of the utility model: the electromagnetic wave shielding layer is made by spraying the electromagnetic wave shielding material.

[0011] As a further solution of the utility model: an anti-bending block is provided at the connection between the VGA connecting cable and the HDMI interface, and an extension groove is provided on the anti-bending block.

[0012] As a further solution of the utility model: a raised anti-slip strip is provided on the plug.

[0013] Compared with the prior art, the beneficial effects of this technical solution are:

[0014] (i) When the user inserts the plug into the corresponding VGA socket, when the direction of the VGA interface is opposite to that of the VGA socket, the sliding cylinder will first cover the nut on the VGA socket. Since the sliding cylinder 501 is slidably connected with the sliding groove 502 provided in the positioning cylinder 5, the position of the plug can be restricted by the two sliding cylinders. When the user does not know that the VGA interface is inserted in reverse and continues to apply force, the VGA interface cannot slide off the VGA socket, thereby preventing the pins from colliding and bending.

[0015] (ii) In the process of transmitting analog signals by the VGA connecting cable, the outer electromagnetic wave absorption layer is used to absorb electromagnetic wave interference from the outside world, and the inner electromagnetic wave absorption layer is used to absorb electromagnetic waves generated by the internal transmission line. At the same time, the electromagnetic wave shielding layer located between the inner electromagnetic wave absorption layer and the outer electromagnetic wave absorption layer is used to shield the electromagnetic waves that are not completely absorbed, thereby preventing the internal transmission line from generating electromagnetic waves that interfere with external electronic equipment, and preventing external electromagnetic waves from interfering with the transmission quality of the transmission line, thereby avoiding image distortion or color deviation problems in the display device.

[0016] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-4 An anti-interference VGA cable that prevents pin bending includes a VGA cable 1, wherein two ends of the VGA cable 1 are respectively connected to an HDMI interface 2 and a plug 3, a VGA interface 301 is provided on the plug 3, and handles 4 are provided on both sides of the plug 3, and the handles 4 are connected to fixing bolts 401 that penetrate the plug 3.

[0031] Embodiment 1

[0032] Please refer to Figure 1-Figure 2 and Figure 4 , positioning cylinders 5 fixedly connected to the plug 3 are provided on both sides of the VGA interface 301, a sliding cylinder 501 is provided on the positioning cylinder 5, and the positioning cylinder 5 and the sliding cylinder 501 can wrap the nut on the VGA socket, the fixing bolt 401 is inside the positioning cylinder 5, a sliding groove 502 is opened on the positioning cylinder 5, and the sliding groove 502 and the positioning cylinder 5 are both cylindrical, the sliding cylinder 501 is slidably connected with the sliding groove 502, and the length of the sliding cylinder 501 is longer than that of the VGA interface 301.

[0033] When the user is inserting the plug 3 into the corresponding VGA socket, when the direction of the VGA interface 301 is opposite to that of the VGA socket, the sliding cylinder 501 will first cover the nut on the VGA socket. Since the sliding cylinder 501 is slidably connected with the sliding groove 502 provided in the positioning cylinder 5, the position of the plug 3 can be restricted by the two sliding cylinders 501, so that when the user does not know that the VGA interface 301 is inserted upside down and continues to apply force, the VGA interface 301 cannot slide off the VGA socket, thereby preventing the pins from colliding and bending.

[0034] On the contrary, if the user inserts in the correct direction, the sliding cylinder 501 first covers the nut, and then as the user continues to apply force, the sliding cylinder 501 presses against the bottom of the VGA socket, and the VGA interface 301 and the positioning cylinder 5 move at the same time. At this time, the VGA interface 301 and the VGA socket are plugged in, and the positioning cylinder 5 is inserted into the nut. At the same time, due to the movement of the positioning cylinder 5, the sliding groove 502 can insert the sliding cylinder 501 inside, and then the handle 4 is turned to screw the fixing bolt 401 into the nut, thereby fixing the plug 3 on the socket.

[0035] Preferably, a spring 503 is fixedly connected to the sliding cylinder 501 , and the spring 503 is fixedly connected to the inner bottom end of the sliding groove 502 .

[0036] When the user inserts the VGA interface 301, if the sliding cylinder 501 is not aligned with the nut on the VGA socket, the body of the sliding cylinder 501 will press against the nut. When the plug 3 is continuously pushed in, the sliding cylinder 501 is likely to slide into the sliding groove 502 in advance. At this time, the spring 503 uses its elastic potential energy to block. When the VGA interface 301 is fully inserted into the VGA socket, the spring 503 is squeezed and deformed when the sliding cylinder 501 moves into the sliding groove 502. After tightening the fixing bolt 401, the reaction force of the spring 503 can be used to improve the firmness of the fixing bolt 401 and the nut, thereby preventing the fixing bolt 503 from loosening.

[0037] Furthermore, the positioning cylinder 5 and the sliding cylinder 501 are both made of high-hardness plastic material. The material used for the positioning cylinder 5 and the sliding cylinder 501 can be PPS (polyphenylene sulfide), so that the positioning cylinder 5 and the sliding cylinder 501 can be insulators while having sufficient strength, thereby preventing the positioning cylinder 5 and the sliding cylinder 501 from interfering with the signal transmission of the VGA connecting line.

[0038] The plug 3 is provided with a raised anti-slip strip 7 , which makes it easier to grasp the plug 3 .

[0039] Embodiment 2

[0040] Please refer to Figure 1-Figure 3 The VGA connecting cable 1 is provided with a transmission line 101, an inner electromagnetic wave absorbing layer 102, an electromagnetic wave shielding layer 103, an outer electromagnetic wave absorbing layer 104 and a plastic outer layer 105 in sequence from the inside to the outside, and the electromagnetic wave shielding layer 103 is made by spraying with an electromagnetic wave shielding material.

[0041] During the process of transmitting analog signals by the VGA connecting cable 1, the outer electromagnetic wave absorption layer 104 is used to absorb electromagnetic wave interference from the outside, and the inner electromagnetic wave absorption layer 102 is used to absorb electromagnetic waves generated by the internal transmission line 101. At the same time, the electromagnetic wave shielding layer 103 located between the inner electromagnetic wave absorption layer 102 and the outer electromagnetic wave absorption layer 104 is used to shield the electromagnetic waves that are not completely absorbed, thereby preventing the internal transmission line 101 from generating electromagnetic waves that interfere with external electronic equipment, and preventing external electromagnetic waves from interfering with the transmission quality of the transmission line 101, thereby avoiding image distortion or color deviation problems in the display device.

[0042] In the embodiment of the present utility model, reference Figure 1-Figure 2An anti-bending block 6 is provided at the connection between the VGA connecting cable 1 and the HDMI interface 2, and an extension groove 601 is provided on the anti-bending block 6. When the HDMI interface 2 is used, the extension groove 601 provided on the anti-bending block 6 can be utilized to improve the bending resistance of the anti-bending block 6, thereby avoiding breaking or rupture at the connection between the VGA connecting cable 1 and the HDMI interface 2.
