All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention, fig. 2 is a schematic specific structure diagram of a first mounting plate 3 shown in fig. 1, and fig. 3 is a schematic specific structure diagram of a second mounting plate 4 shown in fig. 1.
In one embodiment of the invention, the elastic pretension connector device mainly comprises a first mounting plate 3, a second mounting plate 4 and a locking assembly 5.
The first mounting plate 3 is mainly used for mounting the plug 1, the second mounting plate 4 is mainly used for mounting the socket 2, and the first mounting plate and the second mounting plate are opposite to each other, so that the plug 1 and the socket 2 are opposite to each other, and the plug-in matching connection can be conveniently formed.
The locking assembly 5 is a core component, sequentially penetrates through the first mounting plate 3 and the second mounting plate 4, connects the first mounting plate 3 and the second mounting plate 4 to each other, and simultaneously tightens the first mounting plate 3 and the second mounting plate 4 to keep a certain pretightening force between the first mounting plate 3 and the second mounting plate 4, and further keep a certain pretightening force between the plug 1 and the socket 2 after being connected in a plugging manner.
So, the elasticity pretension that this embodiment provided connects and inserts the device, through locking Assembly 5 to first mounting panel 3 with the connection of second mounting panel 4 with taut effect each other, can make plug 1 and socket 2 keep certain pretightning force on keeping the stable basis of inserting and connecting, can strengthen the stability of being connected of plug 1 and socket 2 through this pretightning force, avoid plug 1 and socket 2 to receive the vibration influence and lead to being connected not hard up simultaneously.
In a preferred embodiment regarding the first mounting plate 3 and the second mounting plate 4, the first mounting plate 3 and the second mounting plate 4 may be rectangular plates, and the surface areas of the two may be equal for the convenience of manufacturing. Of course, the specific shape of the first mounting plate 3 and the second mounting plate 4 is not limited to a rectangle, and other shapes such as a circular plate may be used. The relative area of the first mounting plate 3 and the second mounting plate 4 can be adjusted as needed.
For the installation of making things convenient for plug 1 and socket 2, the mounting groove has all been seted up on first mounting panel 3 and second mounting panel 4 to this embodiment. Specifically, the mounting groove may be opened in the middle area between the first mounting plate 3 and the second mounting plate 4, and the plug 1 and the socket 2 may be connected with the mounting groove in a snap-fit manner or detachably connected with a fastening member such as a screw.
In addition, for making things convenient for locking Assembly 5 to run through first mounting panel 3 and second mounting panel 4 with both taut connections, a plurality of mounting hole 6 has all been seted up to this embodiment on first mounting panel 3 and second mounting panel 4. Here, it is preferable that the mounting holes 6 are simultaneously provided in a plurality, for example, 2 to 4, on the first mounting plate 3 and the second mounting plate 4. And, each mounting hole 6 evenly distributed is in the both sides position of mounting groove, and for guaranteeing that locking Assembly 5 can run through first mounting panel 3 and second mounting panel 4 in proper order, each mounting hole 6 that sets up on the two is vertical corresponding each other, and the concrete distribution form of each mounting hole 6 of setting up on the first mounting panel 3 promptly is the same with the concrete distribution form of each mounting hole 6 of setting up on the second mounting panel 4 completely. So set up, after each locking Assembly 5 runs through first mounting panel 3 and second mounting panel 4 and when taut with it, because each locking Assembly 5 distribution position on first mounting panel 3 and second mounting panel 4 is located the both sides position of plug 1 and socket 2, consequently the atress point symmetry, average, the atress of first mounting panel 3 and second mounting panel 4 is balanced, prevents because of the too big slope, the sunken condition that leads to of local atress.

The expansion chuck 52 is disposed at the end (bottom end) of the mounting column 51, and mainly includes a plurality of elastic pieces distributed along the circumferential direction and a tapered structure disposed at the end of the elastic pieces. Each elastic sheet has elasticity, and can be gathered inwards to form a bundle along the circumferential direction or outwards expand to form a petal shape along the circumferential direction. Before the expansion chuck 52 passes through the mounting hole 6, the elastic pieces are first gathered to reduce the diameter passing through the mounting hole 6, and after passing through the mounting hole 6, the elastic pieces are unfolded outwards under the action of elastic force so as to be abutted against the bottom surface of the second mounting plate 4 by using a tapered structure.
The spring 53 is disposed at the head end (top end in the figure) of the mounting post 51, and is mainly used for abutting against the surface of the first mounting plate 3, so that when the mounting post 51 is pressed down through the mounting hole 6, the spring is elastically deformed under pressure, and an upward acting force in the axial direction is generated on the mounting post 51 by using the elastic force, thereby tensioning the expansion chuck 52 at the bottom end of the mounting post 51, so that the expansion chuck 52 is pressed on the bottom surface of the second mounting plate 4, and further the first mounting plate 3 and the second mounting plate 4 are mutually tensioned, and the plug 1 and the socket 2 are also mutually tensioned.
Further, in order to facilitate the installation of the spring 53 at the head end position of the mounting post 51, the present embodiment adds an abutting plate 54 at the head end position of the mounting post 51. Meanwhile, the spring 53 is integrally fitted over the mounting post 51, and the top end of the spring 53 is connected to the bottom surface of the abutting plate 54, while the bottom end of the spring 53 is still abutting on the surface of the first mounting plate 3.
The embodiment further provides a plug-in connection structure, which mainly comprises a plug 1, a socket 2 and an elastic pre-tightening plug-in device, wherein the specific content of the elastic pre-tightening plug-in device is the same as the related content, and the details are not repeated here.
