Description

Electric connection assembly structure of terminal device

Technical Field

The present invention relates to a power connection assembly structure for a terminal device, and more particularly to a power connection assembly structure for a terminal device that is easy and convenient to manufacture and assemble and is stable in combination.

Background

It is known in the art to use metal components or metal spring pieces coated in an insulating housing (usually made of plastic material) to press the wires entering the terminals to form electrically connected connection terminals, and to make the connection terminals snap-fit in an array on a grounding rail (or conductive rail) to establish a common grounding device for electrical or mechanical devices to conduct out the residual voltage or static electricity of those devices.

US 2014/0127932 A1 "electric CONNECTION TERMINAL" discloses that in an electronic CONNECTION TERMINAL (ELECTRICAL CONNECTION TERMINAL), a contact leg (contact leg) at one end of the clamping spring (clamping spring) extends into a space between two protrusions (projections) inside the plastic shell (plastic housing) to form a limit, so that the contact leg (clamping leg) at the other end of the clamping spring can cooperate with the current grid (current bar) to clamp an extended conducting wire, so that the conducting wire is conducted with the grounding rail (or the conducting rail) through the current grid; however, in this structure, since the clamping spring is only positioned by the internal structure of the plastic shell, and there is no connecting and positioning structure between the contact pin and the current grid, in practical applications, the contact pin of the clamping spring and the current grid are easily displaced and separated from each other due to the deformation of the plastic shell (especially after long-term use).

In US 2013/0143433 A1 "CONNECTION TERMINAL" patent, it is disclosed to arrange conductive elastic pieces at two sides inside a housing seat (housing), the conductive elastic pieces are positioned by using the structure inside the housing seat, and one end of the conductive elastic pieces is connected with two ends of a bus bar in a contact manner; the structure is easy to cause the situation that the conductive elastic sheet is separated from the bus and is broken due to the deformation of the plastic shell.

In order to improve the above situation, the prior art discloses a spring plate assembled conductive frame (or current grid) structure; the embodiment provides a state that a person operates the compression and/or rotation elastic sheet to buckle into the conductive frame to form electrical connection. However, as those skilled in the art will appreciate, the above-described combination operation mode is cumbersome and inconvenient.

Typically, the above-mentioned reference data shows that in the related electrical connection terminal, at least one conductive elastic sheet located beside the end of the current grid (or bus) is fixed by using the structure inside the plastic casing seat, so that one end of the conductive elastic sheet is abutted against the current grid (or bus) to form a communication, and the other end of the conductive elastic sheet can elastically contact against the extended wire to form a communication structure, or the elastic sheet is compressed and rotated by the operation of a person to be buckled into the conductive frame; in practical applications, the deformation of the plastic shell easily causes a safety problem of disconnection between the end of the conductive elastic sheet and the current grid (or bus bar), and a problem of troublesome assembly operation, which results in a loss of use.

In order to solve the above problems, a novel electrical connection assembly structure of the terminal device needs to be provided.
