Problems solved by technology

However, although this connection method is simple in design, it is not very ideal. There are unreliable factors such as easy connection disconnection, or stress deformation, etc., and the installation efficiency is low, and the connection is easy to loose. predicted failure
On the other hand, the clamping pieces are generally installed separately on the existing terminal blocks. The clamping pieces for testing required by the industry are all fixed on the copper terminals by screws, and the screws are used for crimping. When crimping, clamping loose
The clamping piece is very inconvenient during assembly and use, which affects signal transmission

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1-3 As shown, the present invention includes a housing 1, at least one terminal assembly 2 is installed inside the housing 1, the terminal assembly 2 includes a terminal 3, and one end of the terminal 3 is provided with a terminal hole 4. There is a downward crimping screw 5 above the terminal post 3, and the crimping screw 5 penetrates into the terminal hole 4; between the crimping screw 5 and the terminal post 3 A thin metal sheet 6 is provided, and an elastic slot 7 is arranged on the thin metal sheet 6 . The elastic slot 7 is formed by clamping two bent elastic small metal sheets on the metal sheet 6 . The metal sheet 6 is bent and extended at one end close to the connection terminal hole 4 to form a clamping piece 9 . The housing 1 is an integrated structure. The housing 1 includes slots for installing terminal a...

Abstract

The invention provides a plug-in terminal strip used for an ammeter. The plug-in terminal strip comprises a housing. The housing is internally provided with at least one terminal assembly. Each terminal assembly comprises a binding post. One end of the binding post is provided with a wiring terminal hole. A downward wire pressing screw is arranged above the binding post. The wire pressing screw penetrates into the wiring terminal hole. A metal thin sheet is arranged between the wire pressing screw and the binding post. The metal thin sheet is provided with an elastic slot. The plug-in terminal strip is reasonable in structure, safe and reliable, and high in installation efficiency.

Description

technical field [0001] The invention relates to the technical field of electronic distribution wire connection devices, in particular to a plug-in terminal block for electric meters. Background technique [0002] In the field of electrical equipment, terminal blocks, as important components, carry and fix multiple or multiple sets of mutually insulated components for line connection and signal transmission, which play a very critical role. [0003] The terminal blocks generally used in the electrical equipment industry mostly use a number of two-two conductive terminals on the terminal block, and use crimping screws to compress and fix the soft wires connected to the terminals, or use connecting pins or The PCB is hardwired to achieve the connection. However, although this connection method is simple in design, it is not very ideal. There are unreliable factors such as easy connection disconnection, or stress deformation, etc., and the installation efficiency is low, and th...
