Description

Use the meter case of wire frame

Affiliated technical field

The utility model relates to a kind of structure of ammeter watchcase.Relate in particular to the wiring position universal air sky of packing into and close a kind of meter case of wire frame assembly or similar mechanism.

Background technology

At present, the ammeter of family expenses and industrial usefulness all contains the binding post that is useful on termination input and output electric wire, in the prior art, has designed multiple different connection terminal wire ends is fastenedly connected, and the modal connection terminal of ammeter is that a metal column is made hollowing out in the middle of it for comprising long piece wiring chamber and wiring pile that binding post is in order to reach certain intensity, tie-in line is big more, binding post must do more, and the material of use is more, consume more resource; And be electric wire to be stretched into screw fasteningly in the post again from above when installing, because screw is directly to be screwed on the conductor of electric wire, make lead impaired even twist into two parts during the turn of the screw easily, cause easily that loose contact and transmission are steady suffers from.

Summary of the invention

For saving cost, and the enhancing ammeter is installed the reliability of wiring, the utility model patent provides a kind of ammeter watchcase, assemble by last watchcase and following watchcase, adopt the ammeter watchcase of this structure not increase the complexity that watchcase is made and assembled, and this watchcase can pack the wire frame assembly of normal air switch into, and then saves the used material cost of connector assembly, and makes that lead inserted more reliable when ammeter was installed.

The utility model patent solves the technical scheme that its technical matters adopts: be made into a meter case with insulating material, when making shell, be divided into a upper casing and a lower casing, upper casing and lower casing assembling back form a main installation room, necessary device and the circuit board of enough laying ammeter reserved in the inner space of main installation room, the housing header board can be made a window that shows usefulness, three wiring chambers are made on meter case top, the independent respectively and reliable mutually insulation in wiring chamber, and being the equal word order of spacing, the direction of opening is identical with the space of installation.The wiring chamber of wire frame being packed into during assembling is used to be respectively charged into the wire frame of electric power live wire incoming line, live wire output line and zero line.After using this wiring cell structure, ammeter can be used wire frame fixture replaces traditional binding post, framework in the wire frame assembly that adopts is that formed by conductive metal sheet die casting and identical with air switch commonly used with the wiring tongue, when realizing connecting lead, external terminal is stretched into wire frame, and the Luo silk of tightening again on the wire frame makes line end get final product with fastening being pressed over of wire frame.This wire frame assembly is common in the assembly of air switch, is to be cast into wire frame and wiring tongue respectively with bullion, and the tail end of wiring tongue connects the lead and the circuit of ammeter inside with the mode of punching press.The wire frame structure that the utility model patent specification is enumerated described shell is mainly used in the electronic electricity meter, uses but be not limited to electronic electricity meter; Cited described shell has three wiring chambers in the utility model patent specification, but the utility model patent is not limited to have only three wiring chambers.

The beneficial effects of the utility model are, because described ammeter housing can use the wire frame of air switch commonly used to replace binding post in traditional ammeter, thereby utilize the advantage of wire frame, overcome waste material and the increase tie-in line problem directly of using binding post to exist in traditional ammeter, ammeter is installed and can be satisfied bigger tie-in line line footpath when having reduced material cost.Simultaneously owing to the wiring tongue is installed when fastening is not followed screw and turn, screw and wiring tongue be to electric power tie-in line conductor not damaged, overcome the traditional wired post use in the fastening impaired problem of wire conductor, improved the reliability that ammeter is connected with electrical network.Because the wire frame assembly that adopts can be identical with air switch commonly used, do not increase the difficulty of making and purchasing in addition, make both manufacturings and procurement method more unified.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the structural drawing after the meter case assembling in the utility model patent, for single wire connecting portion is divided local sectional view.
