[0002] Currently, connection devices are widely used in various industries and are essential components in industrial and daily life. With the advent of the electrification era, the types of electrical connection devices have gradually increased, and people's requirements for electrical connection devices have become higher and higher.

[0003] However, existing connection devices have the following drawbacks:

[0004] Conventional magnetic or snap-fit ​​connections are generally unable to withstand shearing forces to varying degrees, and cannot be reversed, resulting in poor practicality. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a rotary connection device that can solve the problems of being unable to withstand shear force and being unable to reverse the connection.

[0006] One of the objectives of this invention is achieved through the following technical solution:

[0007] A rotary connection device includes a male rotary connection assembly and a female rotary connection assembly. The male rotary connection assembly includes a male base, a protrusion on the male base, and at least two insertion connection ends. The insertion connection ends are arranged around the side of the protrusion, and the protrusion is provided with elastic conductive contacts. The female rotary connection assembly includes a female base, which is provided with a recess corresponding to the protrusion. The recess is provided with a conductive connecting piece, and the female base is provided with at least two engagement grooves. Rotating the male or female rotary connection assembly causes the insertion connection ends to slide into the engagement grooves, making the conductive contacts contact the conductive connecting pieces, thereby engaging and fixing the male and female rotary connection assemblies.

[0008] Furthermore, a sliding gap is provided between adjacent insertion connection ends, and the length of the sliding gap is greater than the length of the insertion connection end.

[0009] Furthermore, the height of the protrusion relative to the surface of the male connector is less than the height of the insertion connection end.

[0010] Furthermore, the number of the insertion connecting ends is the same as the number of the engagement grooves, and the number of the insertion connecting ends is at least two and is evenly surrounding the protrusion or the recess, with the number of the protrusions being the same as the number of the recesses.

[0011] Furthermore, each of the inserted connection ends is provided with a male guide end face on its side, and each of the engagement grooves is provided with a rotary guide end face corresponding to the male guide end face on its side.

[0012] Furthermore, each of the engagement grooves has a sliding guide end face at its front end for guiding sliding in, and the sliding guide end face is in the shape of an inclined plane.

[0013] Furthermore, the male connector body is provided with a mating protrusion, and the female connector body is provided with a mating groove corresponding to the mating protrusion.

[0014] Furthermore, the mating groove is cross-shaped.

[0015] Furthermore, the height of the protrusion corresponds to the depth of the recess, the protrusion is located in the middle of the male seat, and the recess is located in the middle of the female seat.

[0016] Furthermore, the male port seat is provided with a plurality of male port extensions, and the female port seat is provided with a plurality of female port extensions.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The male rotary connector assembly includes a male base, a protrusion on the male base, and at least two insertion connectors. The insertion connectors are arranged around the side of the protrusion, and the protrusion has conductive contacts. The female rotary connector assembly includes a female base with a recess corresponding to the protrusion. The recess has a conductive connecting piece, and the female base has at least two engagement grooves. Rotating the male or female rotary connector assembly causes the insertion connector to slide into the engagement groove, making the conductive contacts contact the conductive connecting pieces, thus engaging the male and female rotary connector assemblies. By using the engagement of the insertion connector and the engagement grooves for the engagement of the male and female rotary connector assemblies, the problem of existing magnetic or snap-fit ​​connectors being unable to withstand shear forces is solved. This method offers high practicality, low production cost, convenient installation, improved electrical performance stability, strong shear resistance, enhanced scalability, and a wide range of applications.

The male rotary connection assembly 10 and the female rotary connection assembly 20 are installed by the cooperation of the insertion connection end 13 and the engagement groove 24. This solves the problem that the magnetic connection device or snap-fit ​​connection device in the prior art cannot withstand shear force.
