Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector which is easy to assemble and disassemble. Background Art

[0002] A connector is a device used to form a current or signal connection between two active devices. The connector usually includes a male connector and a female connector. The male connector includes a male sheath and a male terminal. The female connector includes a female sheath and a female terminal. The male terminal and the female terminal are respectively installed in the male sheath and the female sheath. By plugging and matching the male sheath and the female sheath, the two corresponding terminals are connected and positioned. With the development of connectors, a connector often needs to realize the connection between more functional devices. More male terminals and female terminals are also required in the corresponding connector, which makes the intervals between these terminals smaller, and the male terminal pins are often used. The slender structure is easily bent and damaged during the process of plugging and connecting the male connector and the female connector. For this reason, a connecting cavity for the female sheath to be inserted and a stabilizing frame corresponding to the position of the pin end are often provided on the male sheath. The insertion direction of the female sheath is guided by the connecting cavity, and the position of the pin end is maintained by the stabilizing frame. During the process of plugging the male connector and the female connector, the female sheath drives the stabilizing frame to abut against the male sheath to complete the connection. However, this also means that during the installation of the connector, the operator is often required to move the stabilizing frame to the predetermined position, which is very inconvenient and easy to be overlooked, causing the stabilizing frame to lose its function and causing greater damage to the pin during use.

[0005] The advantage of adopting the above technical solution is that a stabilizing frame and elastically swinging first locking pieces located on both sides of the stabilizing frame are provided in the male end sleeve, and the stabilizing frame can be clamped at the front end of the connecting cavity corresponding to the first locking piece. When inserting the female end sleeve, the female end sleeve can cause the first locking piece to swing laterally to release the clamping of the stabilizing frame, and then drive the stabilizing frame to move together until the stabilizing frame abuts against the bottom of the connecting cavity to complete the installation. Since the stabilizing frame can be clamped at the front end of the female end sleeve, when the male end sleeve and the female end sleeve are separated, the female end sleeve can drive the stabilizing frame back to the front end of the corresponding first locking piece, and as the female end sleeve is withdrawn, the first locking piece is positioned again, which is convenient for the subsequent reinstallation of the female end sleeve and avoids damage caused by the operator ignoring the stabilizing frame.
