Cylindrical plug-in element

Abstract

The invention discloses a cylindrical plug-in element. The cylindrical plug-in element comprises a female plug-in element, a male plug-in element and a locking rod, wherein the female plug-in element comprises a cylindrical first shell and at least three groups of electric conductors, wherein one end of each electric conductor is arranged in the first shell, a first blind groove and a second blind groove which have unequal cross sections are symmetrically arranged on the first shell, a jack is limited between arbitrary two groups of electric conductors, the male plug-in element comprises a cylindrical second shell and at least three insertion sheets, one end of each insertion sheet is arranged in the second shell, the inner diameter of the second shell is slightly larger than the external diameter of the first shell, a first bulge and a second bulge which are matched with the first blind groove and the second blind groove are arranged on the second shell, and the insertion sheets are matched with the jacks and are the same in quantity, so that the male plug-in element and the female plug-in element can be plugged with each other. The plug-in element disclosed by the invention has the advantages of shaking prevention, connection stability, long service lifetime and the like, directional plug can be achieved, and misplug is prevented.

Description

technical field [0001] The invention relates to the technical field of electrical connectors. More particularly, the present invention relates to a securely connected cylindrical connector. Background technique [0002] An electrical connector is a component used to connect two sections of power lines or data lines together for power or electronic data transmission. Its structure is that one section of the line is provided with a male connector, and the other section of the line connected to it is provided with a female connector. Insert the male connector into the female connector to connect the two lines. Because the male connector and the female connector are often plugged and pulled out, the connection is loose and unstable. If this happens for a long time, the connection between the plug on the male connector and the terminal on the female connector will be unstable, which will affect the normal operation of the circuit. In addition, since the male connector of some c...

AI Technical Summary

Problems solved by technology

Because the male connector and the female connector are often plugged and pulled out, the connection is loose and unstable. If this happens for a long time, the connection between the plug on the male connector and the terminal on the female connector will be unstable, which will affect the normal operation of the circuit.

In addition, since the male connector of some connectors is often provided with multiple inserts, which correspond to multiple terminals on the female connector, the correct connection between the connector and the circuit board is unique. , when the insertion direction is correct, the circuit connection can only be realized by connecting with the corresponding terminal, which requires high requirements. However, the existing connector has no guide, and it is easy for the operator to insert it wrongly, resulting in damage to the circuit board.
