Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
Example one
As shown in fig. 1-3, in one embodiment of the present application, a terminal 500, the terminal 500 comprising: a fillet part 100, an intermediate bent part 200 and a wiping part 300 connected in this order,

the sliding part 300 is provided with a second interference area adjacent to the middle bending part 200, and the second interference area is further provided with a twisting position 400.
In this embodiment, by providing the torsion portion 400 in the second interference region, the contact area of the sliding part 300 above the second interference region can be increased, and there are advantages that a fine cutting process is not required, the requirement for the precision of the mold is low, the contact surface is flat, and the like; if the terminal 500 is not twisted, the terminal needs to be in contact with the blanking surface, and the blanking surface generally has problems of small contact area, large surface roughness, poor flatness, corner collapse, high manufacturing cost, poor production stability, and the like.
Further preferably, in this embodiment, the twist angle of the twist position 400 is 90 °, and by setting the twist of 90 °, the characteristic impedance of the contact area terminal 500 can be reduced, which is favorable for high-speed transmission and the like.

The application is applied to plate-to-plate connection, and the welding foot part 100, the middle bending part 200 and the sliding part 300 are arranged, wherein the middle bending part 200 is provided with at least one first bending structure 200A and one second bending structure 200B in the vertical direction and the horizontal direction, and the structures are beneficial to increasing the floating capacity of the application in a limited space;
in the present application, the at least one first bending structure 200A and the at least one second bending structure 200B are arranged to achieve multiple vibration reduction, and are suitable for high vibration environments; on the other hand, due to the deformability of the conductor material of the terminal 500, even if the offset within the preset range occurs at the center position when the plates are connected in a plate-to-plate manner, the effective connection and conduction between the terminal and accessories such as plug conductors can be effectively ensured; on the other hand, the structure is simple, so that the device is suitable for working in certain low-temperature environment and high-temperature environment.
In the description of the present application, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like are used based on the orientations and positional relationships shown in the drawings only for convenience of description and simplification of operation, and do not indicate or imply that the referred device or element must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present application. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
The above embodiments are merely to illustrate the technical solutions of the present application and are not limitative, and the present application is described in detail with reference to preferred embodiments. It will be understood by those skilled in the art that various modifications and equivalent arrangements may be made in the present invention without departing from the spirit and scope of the present invention and shall be covered by the appended claims.
