In addition, be connected by PCB web joint at existing terminal base with ammeter functional template, connecting line is many, and ammeter loop is long, and hot polymerization point is many, and has the quality problems of temperature rise; The built-in on-load switch of existing ammeter is that individual components form is arranged on ammeter terminal base, and the connection of two parts is fixed by securing member, and securing member fixedly exists the instability factor on genetic prerequisite; Metering sampling in intelligent electric meter is easily subject to power frequency magnetic field and disturbs, and easily causes metering distortion; Existing ammeter loop elongated workpieces is many, complex process, and reliable long-term working is not high.

Summary of the invention

The purpose of this utility model is to provide the upper cover of a kind of ammeter terminal base, and this upper cover designs simplification solves ammeter loop long and cause the problem of temperature rise, can realize integrated mechanical with the pedestal of terminal base and install, fixed, use safety, improved product reliability, production cost is low.

For achieving the above object, the utility model is to realize like this, a kind of ammeter is characterized in that by the upper cover of terminal base, comprise cover body, be provided with the wiring hole being connected with outside in the bottom of cover body, be provided with the fixed orifice corresponding with wiring hole in the bottom of cover body, be provided with several binding posts on cover body top, at the fixed head that link post is installed with binding post corresponding position below of cover body, on several binding posts, be all fixed with the contact pin being connected with ammeter functional template, be provided with the jack corresponding with contact pin at fixed head, the side of the left and right sides of cover body is equipped with draw-in groove.

The upper cover of the Novel end stroma that the utility model provides, has following beneficial effect:

From structural member itself, (1), by improving the structural design of upper cover of terminal base, is directly connected with ammeter functional template by contact pin, can reduce a terminal block and Duo Gen connecting contact pin, reduced production cost+, reduced ammeter connecting line; (2) simplify terminal base and subsequent handling production process, significantly reduce required manpower; (3) cancel original PCB web joint and contact pin, directly use plugging mode fix and process, realize shorter loop design, improve the reliability of product, pulling capacity increases by 500 above, does not have the possibility that comes off not destroying under moulding condition; ; (4) improve water proof and dust proof performance, (5) space availability ratio improves, global design compactness.From loop: the design of (6) shortest path, reduces temperature-rise effect thereby reduce impedance loop; (7) reduce hot polymerization effect, electric current bottleneck, improve product reliability; (8) reduce metering sampling error value; (9) simplified processing process, reduces number of parts; (10) fully phase out the use of signal wire or wire, adopt plug-in type to connect to improve quality problems, and manufacturability, simplify manufacturing procedure simultaneously and reduce manpower requirement.
