Description
Technical field
This utility model relates to a kind of guide rail type electrical energy meter, particularly a kind of single-phase double-loop pre-payment guide rail meter.
Background technology
Now with client, the demand of pre-paying kilowatt-hour meter is increasing, the demand of pre-payment guide rail meter also accordingly increases.Traditional pre-payment guide rail meter is generally adopted the mode of connection of upper entering and lower leaving, and the screw of beating that assembling mode is common is fixed.Can there is bigger problem in such design, be difficult to meet the degree of protection of customer requirement on degree of protection.
Summary of the invention
The technical problems to be solved in the utility model is: provide, for above-mentioned Problems existing, the single-phase double-loop pre-payment guide rail meter that a kind of degree of protection is high, effectively to reduce the impact of external environment condition his-and-hers watches internal components, extend ammeter service life, increase stability and reliability.
This utility model be the technical scheme is that unidirectional double loop pre-payment guide rail meter, it includes gauge stand, table cover, terminal base and the pcb board being arranged in gauge stand, the described gauge stand back side offers guide-track groove, described terminal base is made up of input terminal and outlet terminal, and described input terminal and outlet terminal are respectively positioned on gauge stand bottom；The position being connected on described terminal base, with gauge stand and table cover has been integrally machined inserts, and on gauge stand and table cover inwall, corresponding position processing has the scarfing slot matched with described inserts simultaneously, and described inserts embeds the connection realizing terminal base and gauge stand and table cover in scarfing slot.
The cross section of described inserts is step-like, forms the Waterproof passages that a cross section is square waveform between itself and scarfing slot.
Described terminal base is provided with transparent end cap.
Ultrasonic welding process is adopted to be weldingly connected between described gauge stand and table cover.
Described input terminal and outlet terminal adopt upper and lower double-layer structure to arrange.
The beneficial effects of the utility model are: 1, this utility model changes the position of line, namely the mode of connection gone out under entering under adopting, stop the possibility of the wiring hole water inlet of the water point of incoming cables, upper end from product, simultaneously, table cover is attached with the structure of employing inserts and scarfing slot between terminal base with at the bottom of terminal base and table, not only fundamentally improve the degree of protection (degree of protection reaches IP54) of product, and facilitate the assembling of whole table.2, the cross section of inserts is step-like, forms the Waterproof passages that a cross section is square waveform between itself and scarfing slot, it is possible to effectively prevent after external water pressurized inside refluence entrance table meter.3, adopting ultrasonic welding process to be weldingly connected between gauge stand and table cover, after the long-time water spray caused by the assembling mode adopting sealing strip assembling, screw to fix at present, water penetrates into the event within table meter, further increases the water resistance of product.4, the design of the mode of connection and terminal base with at the bottom of table and the coordinating of gauge stand, make product compare with conventional double loop ammeter, overall structure size reduces, and overall appearance is generous.

Detailed description of the invention
As shown in Figure 1-Figure 3, a kind of unidirectional double loop of the present embodiment pre-payment guide rail meter, it includes gauge stand 1, table cover 2, terminal base 3 and is arranged at the pcb board in gauge stand 1, and described gauge stand 1 back side offers guide-track groove 4, and described terminal base 3 is provided with transparent end cap.
Ultrasonic welding process is adopted to be weldingly connected between described gauge stand 1 and table cover 2.Described ultrasonic welding process is the body surface utilizing dither wave loops to two need to weld, when pressurization, and the fusion making two body surface phase mutual friction and being formed between molecular layer.
Described terminal base 3 is formed (adopting upper and lower double-layer structure to arrange) by input terminal 3-1 and outlet terminal 3-2, and described input terminal 3-1 and outlet terminal 3-2 is respectively positioned on gauge stand 1 bottom, namely the mode of connection gone out under entering under adopting, stop the possibility of the wiring hole water inlet of the water point of incoming cables, upper end from product, improve degree of protection.
The position being connected on described terminal base 3, with gauge stand 1 and table cover 2 has been integrally machined inserts 5, simultaneously on gauge stand 1 and table cover 2 inwall, corresponding position processing has the scarfing slot 6 matched with described inserts 5, and described inserts 5 embeds the connection realizing terminal base 3 in scarfing slot 6 with gauge stand 1 and table cover 2.In this example, the cross section of described inserts 5 is step-like, forms the Waterproof passages that a cross section is square waveform between itself and scarfing slot 6, it is possible to effectively prevent from, after external water pressurized inside refluence entrance table meter, improving degree of protection；The degree of protection of this example guide rail meter reaches IP54.
