A high-speed signal transmission cable plug connection guide structure

Abstract

The utility model relates to the field of transmission cables, and in particular to a high-speed signal transmission cable plug connection guide structure. Technical problem: The transmission cable plug is repeatedly connected and unplugged, which makes it loose and misaligned inside, causing the plug and the socket to be easily misaligned or not plugged in properly during the connection process, resulting in a broken contact and reducing the overall connection effect. Technical solution: A high-speed signal transmission cable plug connection guide structure includes a cable plug end, an extension cable, a guide plug assembly, a mating plug assembly and a connection protection plug assembly; unlike the previous method of repeatedly connecting and unplugging, which makes it loose and misaligned inside, the connection protection plug assembly is used to form a pre-external insertion protection operation. As the insertion goes deeper, the protection ring sleeve and the mating connection sleeve are mutually adapted and snap-fitted, and the cable plug end is simultaneously re-entered to connect with the plug core to maintain the guiding connection performance.

Description

Technical Field

[0001] The utility model relates to the field of transmission cables, in particular to a high-speed signal transmission cable plug connection guide structure. Background Art

[0002] A high-speed signal transmission cable plug is a plug used to transmit high-speed signals. There are many kinds of high-speed signal transmission cable plugs, such as HDMI plugs, VGA plugs, Ethernet RJ45 interfaces, etc. The function of the high-speed signal transmission cable plug connection guide structure is to enable the plug and the socket to be connected accurately and quickly. The guide structure can make the plug and the socket perform reinforced connection operations, thereby ensuring the stability and reliability of high-speed signal transmission. During the plugging process, the existing transmission cable plug is loose and misaligned internally due to repeated insertion and removal, which makes it easy for the plug and the socket to be misaligned or not plugged in properly during the connection process, resulting in a broken contact and reducing the overall connection effect. Therefore, we propose a high-speed signal transmission cable plug connection guide structure to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that the transmission cable plug becomes loose and misaligned due to repeated insertion and removal, the plug and socket are easily misaligned or not properly plugged in during the connection process, causing contact breakage and reducing the overall connection effect.

[0004] The technical solution of the utility model is: a high-speed signal transmission cable plug connection guide structure, including a cable plug-in end, an extension cable, a guide plug-in component, a matching plug-in component and a connection protection plug-in component; the lower end of the cable plug-in end is provided with an extension cable for conducting signal connection, the upper end of the cable plug-in end is provided with a guide plug-in component for guiding the plug-in operation, the upper part of the guide plug-in component is provided with a matching plug-in component adapted for installation and connection, and the upper end of the matching plug-in component is provided with a connection protection plug-in component that is integrally formed and connected to protect the connection.

[0005] Preferably, as the insertion goes deeper, the protective ring sleeve and the matching connecting sleeve are adapted and snap-fitted to each other, so that the ring rail rotates circumferentially along the adapting groove, so that the spring column pops out quickly and enters the pressing sleeve to perform a locking operation, and simultaneously enters the cable plug-in end again to connect with the plug-in core to maintain the guiding connection performance.

[0006] Preferably, a sealed insulation sleeve connected to the extension cable is provided at the bottom of the cable plug-in end, an insulating plate is provided around the lower outer end of the cable plug-in end, air holes are provided transversely through the insulating plate, a porcelain sleeve is provided in the center of the sealed insulation sleeve, and plug-in cores are evenly distributed in the middle of the porcelain sleeve. As the environment affects, the airflow is dissipated through the air holes.

[0007] Preferably, a barrier ring is provided along the extension cable for preventing shaking and contact protection, and barrier grooves are provided on both sides of the barrier ring. The barrier ring is used to prevent the extension cable from deflecting, reduce pulling and tearing, and form protective performance.

[0008] Preferably, the guide plug-in assembly includes a guide movable sleeve, a positioning column and a guide spring sleeve. A movable groove is provided between the guide movable sleeve and the cable plug-in end. A positioning column is provided around the inner side of the guide movable sleeve. The guide movable sleeve is elastically adjusted along the positioning column through the guide spring sleeve. A spring damping is provided inside the guide spring sleeve so that the spring column can pop out quickly and enter the pressing sleeve.

[0009] Preferably, the mating plug-in assembly includes a mating connecting sleeve, a spring column, a ring rail, a center through ring and a stacked sleeve. A center through ring is provided in the center of the mating connecting sleeve, a ring groove is provided between the mating connecting sleeve and the center through ring, a ring rail is provided on the inner side of the mating connecting sleeve near the edge, a spring column is provided in a circumferential direction on the ring rail, a spring damper is provided inside the spring column, and multiple groups of stacked sleeves are provided between the mating connecting sleeve and the guide plug-in assembly.

[0010] Preferably, the connection protection plug-in assembly includes a toggle handle, an anti-sliding block, a limiting sleeve, a pressing sleeve and a protective ring sleeve. An adaptation groove is provided at the bottom of the protective ring sleeve, a toggle handle is provided at the bottom outer end of the protective ring sleeve, and an anti-sliding block is provided at the center of the toggle handle. Through the toggle handle, the protective ring sleeve and the matching connecting sleeve are adapted and snapped together to enable the ring rail to rotate circumferentially along the adaptation groove.

[0011] Preferably, a limiting sleeve is provided in an annular direction at the bottom center of the adapter groove, a pressing sleeve is provided at the upper end of the limiting sleeve, the pressing sleeve is provided in two sets, and a snap-in groove is provided in an annular direction on the outer side of one end of the protective ring sleeve away from the limiting sleeve. Due to the different lengths and thicknesses of cables, the snap-in groove can be used for annular buckling.

[0012] Beneficial effects of the utility model:

[0013] 1. Different from the previous practice of repeated insertion and removal, which causes internal loosening and misalignment, the use of a connection protection plug-in assembly can form a pre-external insertion protection operation. As the insertion goes deeper, the protection ring sleeve and the matching connection sleeve are adapted and connected to each other, so that the ring track rotates circumferentially along the adaptation groove, so that the spring column quickly pops out and enters the pressing sleeve to perform a locking operation, and simultaneously enters the cable plug-in end and connects with the plug core again to maintain the guided connection performance.

[0014] 2. Due to the different lengths and thicknesses of cables, the snap-in groove can be used for circumferential buckling, and then the insulating plate can be grabbed for circumferential holding. The guide sleeve is elastically adjusted along the positioning column through the guide spring sleeve, which can better connect the plug core, and then rebound to provide in-depth protection and increase the overall installation performance.
