Description

A kind of earpiece erecting device

Technical field

The utility model relates to mobile phone device installing area, particularly a kind of earpiece erecting device.

Background technology

Mobile phone is more and more universal in the life of people, and the requirement of terminal use to mobile phone is also more and more higher! Production and assembly are simple and fast more and more, in this case, the assembling of electronic devices and components needs design more convenient, needing at utmost to reduce the operational error of operator brings cell-phone function to lose efficacy, and the way of contact that connects that on current mobile phone, receiver is conventional is spring-piece type, should be noted that the assembly direction of receiver during assembling, if anti-loaded, can cause disabler, this mode by operating personnel's manual control, there will be the risk of inefficacy in production and assembly process.

In order to solve the problems of the technologies described above, prior art is by increasing silk-screen layer at the enterprising line identifier of pad, this scheme is when PCB makes, increase manufacture craft, the corresponding increase of PCB Production Time, cost also increases thereupon, Given this, needs a kind of without the need to increasing technique, guaranteeing to install errorless low cost pad again.

Utility model content

For mentioned problem, the utility model provides a kind of earpiece erecting device, comprising:

Receiver substrate, its location is arranged in handset front case;

Two panels shell fragment, it is arranged on the same side of described receiver substrate, and described two panels shell fragment one side is connected with described receiver substrate, the contact pads of another side and circuit board;

Pad, it is separately positioned on circuit board of mobile phone, on pad covering board corresponding shell fragment and with the region of shell fragment along described receiver substrate center line mirror image.

Preferred version is: described pad is rectangle.

It is larger than circular pad solder intensity that pad is generally circular and square, square pad, and reliability is high.

Preferred version is: described pad is 2 rectangular pads, its respectively on covering board corresponding shell fragment and with the region of shell fragment along described receiver substrate center line mirror image.

Two pieces of rectangular pads cover the join domain corresponding to described shell fragment and mirror point thereof on circuit boards respectively, even if receiver substrate is anti-loaded like this, also can not reduces the anti-device of weldering and cause doing over again or circuit board damage.

Preferred version is: described pad is 4 rectangular pads, its respectively on covering board corresponding shell fragment and with the region of shell fragment along described receiver substrate center line mirror image.

4 rectangular pads cover the region corresponding to described shell fragment and mirror point thereof on circuit boards respectively, even if receiver substrate is anti-loaded like this, also can not reduces the anti-device of weldering and cause doing over again or circuit board damage.

The utility model adopts the mode of the overlay area increasing pad on circuit board, not only increase the efficiency of assembling, and reduce the anti-device of weldering and cause doing over again or circuit board damage, simultaneously, pad mark is carried out in making and the production that need not increase silk-screen layer, decrease the manufacture craft of circuit board, reduce the cost of circuit board.

Accompanying drawing explanation

Fig. 1 is receiver substrate of the present utility model and handset front case installation diagram;

Fig. 2 is the location drawing of shell fragment of the present utility model at receiver substrate;

Fig. 3 is the pad location drawing on circuit boards in prior art;

Fig. 4 is the utility model embodiment 1 location drawing on circuit boards;

Fig. 5 is the utility model embodiment 2 location drawing on circuit boards.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.

Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.

The way of contact that on current mobile phone, receiver is conventional is spring-piece type, the assembly direction of receiver is should be noted that during assembling, as shown in Figure 3, pad 3,4 is fixed on a position, if receiver substrate is anti-loaded, can cause disabler, this mode by operating personnel's manual control, there will be the risk of inefficacy in production and assembly process.

Embodiment 1

The utility model provides a kind of earpiece erecting device, as shown in Fig. 1,2,4, comprising:

Receiver substrate 11, its location is arranged in handset front case 12;
