Description

Technical Field

[0001] The invention relates to the field of connectors, in particular to a composite unlocking connector. 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. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a composite unlocking connector which is convenient for assembly and disassembly, has strong stability and is not easily damaged.

[0004] To achieve the above-mentioned purpose, the present invention provides a composite unlocking connector, including a male end sleeve and a female end sleeve, a stabilizing frame is arranged in the male end sleeve, the female end sleeve is plugged into and matched with the male end sleeve, a connecting cavity for inserting the female end sleeve is arranged in the male end sleeve, a first mounting position and a second mounting position are arranged in the connecting cavity, the first mounting position is arranged near the middle of the connecting cavity, the stabilizing frame can be clamped at the first mounting position of the connecting cavity, and the female end sleeve can cause the stabilizing frame to release the clamping fit with the connecting cavity and drive it to move to the second mounting position during the process of inserting the female end sleeve into the connecting cavity, when the stabilizing frame is located at the second mounting position, the two end faces of the stabilizing frame can respectively abut against the bottom of the connecting cavity and the end of the female end sleeve, and can form a clamping fit with the female end sleeve, and the process of the female end sleeve withdrawing from the connecting cavity can drive the stabilizing frame to reset and be clamped at the first mounting position of the connecting cavity.

[0005] The advantages of adopting the above technical solution are: a connecting cavity and a stabilizing frame are set on the male end sleeve, and a first installation position and a second installation position are set in the connecting cavity, so that the stabilizing frame can be clamped at the first installation position, and when the male end sleeve and the female end sleeve are not inserted and connected, the stabilizing frame can assist in maintaining the position of the male terminal pin. Later, when the female end sleeve is inserted into the connecting cavity, the female end sleeve can prompt the stabilizing frame to release the clamping fit with the connecting cavity, and then push the stabilizing frame to the bottom of the connecting cavity, which will not hinder the insertion process, and when the female end sleeve is subsequently withdrawn from the connecting cavity, the female end sleeve can drive the stabilizing frame to reset and clamp it at the first installation position of the connecting cavity, which makes it possible to insert the male end sleeve and the female end sleeve again without adjusting the stabilizing frame, and can play an auxiliary guiding and protecting effect on the pin, thereby simplifying the operation and avoiding the risk of ignoring the stabilizing frame and directly installing the pin to cause damage, making the product more stable.
