Description
Technical field
The utility model relates to buzzer technical field more particularly to a kind of buzzers for electric energy meter.
Background technique
Buzzer is a kind of electro-acoustic transducing device, is mainly used in and is widely used in electric energy meter, computer, printer, answers
In the electronic products such as print machine, alarm, electronic toy, vehicle electronics, telephone set, timer.The buzzer of the prior art,
Its pin be direct riveting on circuit boards, it is bad with circuit board contacts to may result in pin because of technological reason in this way,
And then cause reliability lower, and the prior art easilys lead to buzzer peace there is no differentiation pin is removed well in this way
Wrong plug pin when dress.
Summary of the invention
It is not easy wrong plug when and a kind of installation higher the technical problem to be solved by the utility model is to provide reliability
Buzzer.
The technical scheme adopted by the utility model is a kind of buzzer, including shell, setting are in the intracorporal pcb board of shell
And two operational pins outside shell are riveted on pcb board and stretch out, at two operational pins and pcb board riveting also
Tin layers are enclosed with, and are additionally provided with an empty pin outside shell.
Preferably, the tin layers are high temperature resistant tin layers.
Preferably, the height of two operational pins is identical.
Preferably, the sky pin is identical as the height of two operational pins.
Preferably, the sky pin and two operational pins form an isosceles triangle.
Preferably, the sky pin is riveted at pcb board nonfunctional area.
Preferably, also needing to wrap up one layer of glue after the tin layers wrapped up at two operational pins and pcb board riveting
Layer.
Preferably, the glue layer is high-temperature-resistant glue layer.
It is made preferably, two operational pins are all made of copper product with an empty pin.
Preferably, chamfered is done in one end that two operational pins and an empty pin stretch out shell.
Using the above structure compared with prior art, the utility model has the advantage that at riveting in setting one
Layer tin layers, so that fixed between operational pin and PCB stronger, it is not easy to fall off, reliability is higher, and is provided with
One empty pin, such user can judge the positive anti-plug of buzzer according to the position of empty pin, can prevent from inserting in this way
It is wrong.
Be arranged to high temperature tin layers, in this way may high temperature resistant, reliability is higher.
The height of two operational pins is done identical, so that more convenient when installation.
Empty pin and two operational pins are formed into isosceles triangle, it is easier for installation for grafting in this way.
Empty pin is riveted at pcb board nonfunctional region, will not influence the normal function of pcb board, Er Qieyou in this way
The fixed empty pin of place installation.
One layer of glue layer is set, can to fix between operational pin and pcb board stronger.
Pin is made using copper product, such pin reliability is higher.
Chamfered is carried out to pin, can prevent pin from stabbing hand in this way.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of buzzer of the utility model.
It is as shown in the figure: 1, shell；2, operational pin；3, empty pin.
Specific embodiment
The utility model is described further below in conjunction with attached drawing and specific embodiment, but the utility model is not only
It is limited to following specific embodiments.
A kind of buzzer including shell 1, is arranged in the intracorporal pcb board of shell, is arranged on pcb board and stretches out outside shell
Two operational pins 2 and an empty pin 3, in which:
Two operational pins and an empty pin are riveted on pcb board, and two operational pins are to be riveted on
The working region of pcb board, and also need that one layer of high temperature resistant tin layers are arranged at two operational pin rivetings, later in one layer of setting
High-temperature-resistant glue layer, empty pin are the useless regions for being riveted on pcb board.
And two operational pins are using made of copper product, and empty pin can also use copper product, can also be with
Using other materials.
And two operational pins 2 and an empty pin 3 stretch out shell, and stretching out one end all is by chamfered
, or process in the arc-shaped.
And the processing method of this buzzer is as follows:
S1, magnet ring aging；
S2, clear magnetic；
S3, operational pin one end is riveted on pcb board, while empty pin is riveted on pcb board；
S4, by after riveting operational pin one end and the junction PCB add high temperature resistant tin；
S5, point skeleton；
S6, coiling；
S7, glue magnet ring；
S8, glue wiring board；
S9, on off test；
S10, solder joint cementing；
S11, clear magnetic；
S12, semi-finished product high/low temperature aging；
S13, assembly；
S14, primary test；
S15, epoxy resin is poured；
S16, audiometry；
S17, tooling aging；
S18, high temperature sonic test；
S19, second test；
S20, lettering；
S21, the operational pin other end dip in high temperature tin, remove the foreign matter on operational pin；
S22, the whole foot of the operational pin other end；
S23, visual examination；
S24, acceptance inspeciton；
S25, mouth is sealed；
S26, packaging.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
It can so modify to technical solution documented by previous embodiment, or part of technical characteristic is replaced on an equal basis
It changes；And these are modified or replaceed, and the essence of corresponding technical solution is not made to be detached from various embodiments of the utility model technical side
The spirit and scope of case.
