Description
Technical field
It the utility model is related to electric energy meter component technology field, more particularly to a kind of spring compression joint type terminal box.
Background technology
With the development of society, the continuous transformation and innovation of electric utility, various functions ammeter constantly produce, current electricity
Energy table, either mechanical or electronic electric energy meter, the mode of connection of its terminal box is mostly the Current Mutual Inductance inside meter
Electric current copper core in device is all that the input and output wire outside meter is with screws tighten on the wiring copper bar on the inside of terminal box
Penetrate in the electric current wiring hole of copper bar, then directly compress wire with screw again, such mode of connection, be all manually to tighten
, loose contact caused by not tightening be present, or even cause the adverse consequences such as burn；Other screw is tightened in rotation
When, the spiral of screw is easily damaged wire；Need to turn fastening screw during this wiring, whole process operational ton is big, and leads to
Normal electric energy meter installation site is higher, and such mode of connection can undoubtedly bring many unnecessary troubles to the maintenance in later stage, increase
The workload of staff is added so that human capital increase, in addition, can not be completely secured when turning fastening screw
The reliability of wiring connection.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of simplified mounting process, and facilitate the bullet of plug wiring
Spring compression joint type terminal box.
In order to solve the above technical problems, the utility model is addressed by the following technical programs：A kind of spring compression joint type
Terminal box, including the binding post being arranged on terminal box, the binding post include housing, the terminal being arranged in housing
Seat, the terminal base is internally provided with cavity, elastic compression joint structure setting on the cavity top, and with an end set in
The binding post copper sheet of the cavity bottom coordinates.
In such scheme, it is preferred that the terminal base can set terminal base at least provided with one according to being actually needed
Quantity.
In such scheme, it is preferred that alignment pin is provided with the cavity wall, for the elastic compression joint knot in cavity
Structure positions, crimping failure caused by preventing its sliding.
In such scheme, it is preferred that the elastic compression joint structure is Y types including the rotational handle with bayonet socket and section
Spring pressuring plate, by rotational handle drive spring pressuring plate elastic deformation after dock the end of a thread realize crimping, replace spiral shell so as to reach
The effect of bolt.
In such scheme, it is preferred that the positioning finger setting in the rotational handle and the spring pressuring plate transit chamber body, bullet
Spring tabletting by with the bayonet fittings in rotational handle, realize compression and the release of spring pressuring plate butted line.
In such scheme, it is preferred that be provided with locating button on the spring pressuring plate, when locating button is used for crimpless state with
Step-like position limiting structure in cavity wall coordinates, and ensureing that spring pressuring plate will not glide causes to fail.
The utility model compared with prior art, has the advantages that：By setting elasticity inside binding post
Crimping structure, connecting wire, which can not only be effectively ensured, to be damaged because of when fixing, and be able to ensure that good between wire and copper core
It is good reliably to contact, while make that wire installment work is greatly simplified, installation quality has obtained basic guarantee, or even subsequently tieed up
Shield is more convenient when disassembling.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 6, a kind of spring compression joint type terminal box, including the binding post being arranged on terminal box, it is described to connect
Line terminals include housing 1, the terminal base 2 being arranged in housing, and the terminal base is internally provided with cavity, and elastic compression joint structure is set
Put on the cavity top, and coordinate with copper lug 3 of the end set in the cavity bottom, the terminal base 2 is set
Four are equipped with, alignment pin 23 is provided with the cavity wall, the elastic compression joint structure includes the rotation hand with bayonet socket 211
Handle 21 and section are the spring pressuring plate 22 of Y types, the positioning in the rotational handle 21 and the transit chamber body of the spring pressuring plate 22
Pin 23 is positioned, and locating button 221 is provided with the spring pressuring plate 22.
During elastic compression joint structure initial position, spring pressuring plate 22 root card of the section for Y types and the card in rotational handle 21
In mouthfuls 211, be provided with the spring pressuring plate 22 locating button 221 block and the step-like position limiting structure 24 in cavity wall on, prevent
Loosen, after connecting wire is assembled, rotational handle 21 is pulled towards the bottom direction of terminal base 2, now, bayonet socket 211 is with rotation
Handle 21 rotates clockwise, and the side of bayonet socket 211 pushes to spring pressuring plate 22, drives the y-type structure of spring pressuring plate 22 towards wiring copper
The direction movement of piece 3, so as to realize the crimping to connecting wire, it is necessary to when extracting connecting wire, it is only necessary to by rotational handle 21
Counterclockwise pull, with release of the side of bayonet socket 211 to the pressure of spring pressuring plate 22, spring pressuring plate 22 recoils to bayonet socket again
In 211, the y-type structure of spring pressuring plate 22 leaves the wire of crimping therewith, now, you can easily extracts connecting wire.
In such scheme, terminal base 2 is provided with four, in practice environment, terminal base can increase according to demand or
Reduce, to coordinate actual functional requirement, coordinate elastic compression joint structure, it is more stable effectively to realize that the connecting wire for exempting from bolt is consolidated
It is fixed, it is applicable to multiple fields.
The scope of protection of the utility model includes but is not limited to embodiment of above, and the scope of protection of the utility model is to weigh
Sharp claim is defined, and any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement are each fallen within
The scope of protection of the utility model.
