Electric connection terminal and relay socket thereof

Abstract

The invention discloses an electric connection terminal and a relay socket thereof. The electric connection terminal is provided with at least one extension arm at the head part of the free end of a spring plate along the extension direction of the free end from the side, one side of the holding part of a connecting piece is at least provided with a first gap, the extension arm passes through thefirst gap of the corresponding side of the holding part of the connecting piece, and is pressed on the top end of the corresponding first gap elastically and is pushed to supporting legs at the bottom of an operating lever. When the two sides of the spring plate are respectively provided with one extension arm and the two sides of the connecting piece are respectively provided with two first gaps, the free end of the spring plate, the extension arm and the connecting piece form a square socket hole to make an electric conductor be inserted into a holding cavity and pressed with the holding part of the connecting piece. The structure of the invention can achieve the installing and dismounting of the electric conductor without the tools preferably, as well as can prevent the electric conductor from rolling out from the two sides of the free end of the spring plate and from the two sides of the connecting piece, further, the invention has the advantages of less application force, safe and reliable connection, simple structure, and the like.

Description

technical field [0001] The invention relates to an electric connection terminal, in particular to an electric connection terminal for connecting electric conductors and a relay socket thereof. Background technique [0002] The electrical connection terminal is one of the commonly used components in electrical equipment. Its function is to connect the electrical conductor. The traditional electrical connection terminal usually uses screws to lock the electrical conductor to the terminal. When disassembling, it is necessary to unscrew the screw to The electric conductor is removed, thus causing a lot of inconvenience to the disassembly and assembly of the electric conductor. In order to facilitate the disassembly and assembly of electrical conductors, an existing electrical connection terminal includes a connecting piece, a clamping elastic piece and an operation button. The clamping elastic piece has a fixed end and a free end. The fixed end of the clamping elastic piece is u...

Problems solved by technology

The advantage of this kind of electrical connection terminal is that the electrical conductor can be tightly connected to the connecting piece. The disadvantage is that in order to ensure that the electrical conductor can be firmly connected in the terminal composed of the elastic piece and the connecting piece, the elastic force of the elastic piece must be large enough. , since the button is arranged in the free end close to the fixed end, when installing and disassembling the electric conductor and needing to open the accommodation cavity between the shrapnel and the connecting piece, a large operating force is required, and sometimes tools are needed to open it; One disadvantage is that the free end of the clamping shrapnel uses its elastic force to directly abut the electrical conductor against the connecting piece, which cannot effectively prevent the electrical conductor from slipping out from both sides of the free end of the shrapnel and the two sides of the connecting piece
