[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of protection of the present invention.

[0029] The application principle of the present invention is described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-2 As shown, the present invention provides a jack assembly, comprising a shell conductor 1, and a first elastic sheet 2 and a second elastic sheet arranged in the shell conductor 1;

[0031] like Figure 7 As shown, in a specific embodiment of the present invention, the shell conductor 1 is a hollow structure with a rectangular cross section, and notches are provided on the four side walls for inserting the plug 3; when the spring piece is installed longitudinally or transversely, the plug 3 is inserted from the corresponding notch accordingly; in other embodiments of the present invention, the cross section of the shell conductor 1 can also be other shapes, as long as it can cooperate with the first spring piece 2 and the second spring piece to realize multi-directional insertion of the plug;

[0032] like Figure 8 As shown, the first spring piece 2 and the second spring piece are arranged opposite to each other, and the gap between them is used for inserting the insert piece 3. The first spring piece 2 and the second spring piece have the same structure, and both include two oppositely arranged connecting pieces, a plurality of contact components arranged in sequence, and a plurality of first contact cantilevers 23;

[0033] Each contact assembly includes an arc-shaped contact strip 24 and a second contact cantilever 241. The extension direction of the arc-shaped contact strip 24 is consistent with the plug direction of the jack assembly. Two second contact cantilevers 241 arranged opposite to each other are respectively provided on both sides of the arc-shaped contact strip 24. One end of the second contact cantilever 241 is connected to the arc-shaped contact strip 24, and the other end is in a suspended state for contacting the housing conductor 1.

[0034] Two oppositely arranged first contact cantilevers 23 are provided between adjacent arc-shaped contact strips 24, one end of each first contact cantilever 23 is connected to the corresponding connecting piece, and the other end is in a suspended state for contacting the plug-in; that is, the first contact cantilever 23 and the second contact cantilever 2411 are both inclined, and the two are respectively located on both sides of the arc-shaped contact strip 24.

[0035] It can be seen that based on the above design, when the spring sheet is installed in different directions, multi-directional insertion of the adapter plug can be achieved, and the contact position between the spring sheet and the plug is divided into three layers along the plug-in direction, wherein the first contact cantilever 23 is the first layer, the arc-shaped contact strip 24 is the second layer, and the second contact cantilever 241 is the third layer, which effectively reduces the plug-in force while ensuring reliable contact.

[0036] In a specific implementation of this embodiment, in order to fix the first spring piece 2 and the second spring piece to the shell conductor 1, a through hole 22 is provided on the connecting piece, and a protrusion 11 corresponding to the through hole 22 is provided on the shell conductor 1. When the protrusion 11 is located in the corresponding through hole 22, the first spring piece 2 and the second spring piece are fixed to the shell conductor 1.

[0037] In a specific embodiment of the present invention, Figure 8 As shown, the connector is strip-shaped, symmetrically arranged on both sides of each contact component, and connected to the end of each contact component. In a specific embodiment of the present invention, the connector can also be in other shapes as long as it can connect the contact components.

[0038] In a specific implementation of this embodiment, Figure 5 and 8 As shown, the two opposite ends of the first elastic sheet 2 and the second elastic sheet are both provided with flange structures 21, and the extension direction of the line connecting the two ends is the same as the insertion direction of the jack assembly, which is used for guiding and limiting functions.

[0039] In a specific implementation of this embodiment, in order to improve the connection uniformity of the jack assembly and facilitate production and manufacturing, each second contact cantilever 241 is connected to the arc-shaped contact strip 24 at equal intervals.

[0040] In a specific implementation of this embodiment, the cross-section of the arc-shaped contact strip 24 is cross-shaped, including a first section and a second section that are perpendicular to each other, and one end of each second contact cantilever 241 is connected to a portion of the first section located on both sides of the second section, thereby increasing the contact points with the shell conductor 1 and improving electrical connectivity, that is, four second contact cantilevers 241 are connected to one arc-shaped contact strip 24.

[0041] In a specific implementation of this embodiment, there is a gap between the first contact cantilevers 23 that are arranged opposite to each other, so as to reduce the possibility of interference between the first contact cantilevers 23 .

[0042] like Figure 1-2 The figure shows a schematic diagram of a jack assembly with springs installed longitudinally. Figure 3 The insert piece 3 can be inserted longitudinally into the socket assembly in the manner described above. Figure 4-5 The figure shows a schematic diagram of a jack assembly with a horizontally mounted spring. Figure 6 In this way, the insert piece 3 can be longitudinally inserted into the jack assembly.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
