[0002] Connectors are essential components for all types of electrical and electronic systems. They have become essential for interconnecting complex product modules and are widely used in industries such as aerospace, aviation, nuclear power, weapons, ships, electronics, transportation, computing, communications, healthcare, and oil exploration. In circuits, electrical connectors serve as the "nerve hub" and connection point of electrical signal transmission systems, playing a crucial role in signal transmission. Their quality directly impacts product performance and quality. Electrical connectors are primarily used to connect cables and cables, and cables and equipment, in electrical and electronic equipment, enabling the transmission of low-frequency and high-frequency signals, as well as electrical energy and power.

[0003] Common electrical connectors consist of two parts: a fixed electrical connector and a free-end electrical connector. The fixed electrical connector is a passive connection part installed on the panel and the base, also known as a socket; the free-end electrical connector is an active connection part with a connecting nut or other locking device, which cooperates with the fixed-end electrical connector, also known as a plug. The electrical connector connects and disconnects the circuit through the engagement and separation between the plug and the socket. In order to make the electrical connector connection more secure, a threaded connection method is usually adopted. A rotatable threaded sleeve is provided on the outside of the free-end electrical connector, and an external thread is provided on the surface of the fixed electrical connector. The free-end electrical connector and the fixed electrical connector are tightly connected by the thread. In order to increase the speed of connection, a snap-on method is usually adopted for quick connection.

[0004] However, when the common electrical connector snap-in method is used on some equipment with large vibrations, the electrical connector can easily be loosened due to the vibration of the equipment, resulting in connection interruption, and the threaded connection method is not fast enough. In view of this, the present application proposes a rotary snap-in electrical connector. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a rotary snap-on electrical connector, which has the advantages of quick connection through rotary snap-on and improved connection reliability. It solves the problem that the common electrical connector snap-on method is easy to loosen the electrical connector due to vibration of the equipment when used on some equipment with large vibrations, resulting in connection interruption, while the threaded connection method is not fast enough.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a rotary clamping electrical connector, comprising a movable body and a fixed body, a connecting ring fixedly mounted on the surface of the movable body, a connecting housing rotatably mounted on the surface of the connecting ring, and a connecting structure disposed inside the connecting housing;

[0007] The connection structure includes four positioning grooves opened on one side of the connection shell, and the inner side wall of the connection shell is provided with an annular groove, the positioning groove is connected to the annular groove, and a stopper is fixedly installed inside the annular groove on one side of the positioning groove.

[0008] Furthermore, a rotation groove is formed on the inner side wall of the connecting shell, and the connecting shell is rotatably mounted on the surface of the connecting ring through the rotation groove.

[0009] Furthermore, a connecting column is fixedly installed on one side of the fixed body, and four clamping columns are fixedly installed on the surface of the connecting column, and the clamping columns are adapted to the positioning groove and the annular clamping groove.

[0010] Furthermore, a pin is fixedly mounted on one side of the movable body, and a socket adapted to the pin is provided on one side of the connecting column.

[0011] Furthermore, a fixed ring plate is fixedly installed on the surface of the movable body, and a fixed spring is fixedly installed on a side of the fixed ring plate away from the connecting shell.

[0012] Furthermore, a fixed rod is inserted into the interior of the fixed spring, a movable ring plate is slidably installed on the surface of the movable body, one end of the fixed rod is fixedly connected to the movable ring plate, and one end of the fixed spring is fixedly connected to one side of the movable ring plate.

[0013] Furthermore, a fixing hole adapted to the fixing rod is opened on one side of the connecting shell, the fixing rod is slidably connected to the connecting shell through the fixing hole, and a wire is fixedly installed on one side of the movable body.

[0014] Compared with the prior art, the present invention provides a rotary clamping electrical connector with the following advantages:

[0015] The rotary snap-fit ​​electrical connector is constructed by arranging a connecting shell on the surface of a movable body, arranging a connecting structure inside the connecting shell, aligning a positioning groove with a snap-fitting column on the surface of a connecting column on one side of the fixed body, inserting the connecting column into the interior of the connecting shell, and then rotating the connecting shell so that the snap-fitting column is snapped into the annular snap-fitting groove, thereby realizing a quick connection between the movable body and the fixed body. At the same time, a fixing rod is inserted into a fixing hole on one side of the connecting shell to fix the connecting shell and prevent the connecting shell from rotating. This solves the problem that a common electrical connector snap-fitting method, when used on some equipment with large vibrations, is prone to loosening the electrical connector due to the vibration of the equipment, resulting in connection interruption, while a threaded connection method is not fast enough.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 A rotary snap-fit ​​electrical connector includes a movable body 1 and a fixed body 5. A connecting ring 2 is fixedly mounted on the surface of the movable body 1, a connecting shell 3 is rotatably mounted on the surface of the connecting ring 2, and a connecting structure 4 is provided inside the connecting shell 3.

[0023] At the same time, the connecting structure 4 includes four positioning grooves 41 opened on one side of the connecting shell 3, and the inner wall of the connecting shell 3 is provided with an annular groove 42. The positioning grooves 41 are connected to the annular grooves 42, and a stopper 43 is fixedly installed inside the annular groove 42 on one side of the positioning groove 41.

[0024] The inner side wall of the connecting shell 3 is provided with a rotation groove 31 , and the connecting shell 3 is rotatably mounted on the surface of the connecting ring 2 through the rotation groove 31 .

[0025] Secondly, a connecting column 6 is fixedly installed on one side of the fixed body 5 , and four clamping columns 7 are fixedly installed on the surface of the connecting column 6 . The clamping columns 7 are adapted to the positioning groove 41 and the annular clamping groove 42 .

[0026] A pin 8 is fixedly mounted on one side of the movable body 1, and a socket 9 is formed on one side of the connecting post 6 to accommodate the pin 8. Align the connecting post 7 with the positioning slot 41, then press the movable body 1 toward the fixed body 5, inserting the pin 8 into the socket 9. Simultaneously, the connecting post 7 passes through the positioning slot 41 and enters the annular groove 42. The connecting housing 3 is then rotated to engage the connecting post 7 in the annular groove 42.

[0027] At the same time, a fixed ring plate 10 is fixedly installed on the surface of the movable body 1 , and a fixed spring 11 is fixedly installed on a side of the fixed ring plate 10 away from the connecting shell 3 .

[0028] Among them, a fixed rod 12 is passed through the interior of the fixed spring 11, and a movable ring plate 13 is slidably installed on the surface of the movable body 1. One end of the fixed rod 12 is fixedly connected to the movable ring plate 13, and one end of the fixed spring 11 is fixedly connected to one side of the movable ring plate 13.
