The electric connector of flat type vibration source
Technical field
The present invention relates to a kind of electric connector of flat type vibration source; Especially also relate to a kind of vibration source, this vibration source has and is installed to specified position quickly and easily gets under the prerequisite of not sacrificing overall dimensions.
Background technology
Along with the fast development that science and technology is maked rapid progress, also carrying out in the mobile phone in the Portable, personal communication system, the beep-pager etc. to volume trend development littler, with better function; And the flat type vibration source that provides vibrating function to use to above-mentioned utensil is the keen competition of unit carrying out one with the micron order also.As you know, have in the person communication system one very important function remind the user that the information incoming call is arranged exactly, be exactly to adopt music at present the most widely, ringer function also has and a kind ofly reminds the user that the information incoming call is arranged by the mode that machine itself is trembled exactly.This function is particularly useful at the environment that the crowd is dense, perhaps night after people sleep soundly, alarms other people and produces noise avoiding.Theme of the present invention is exactly the flat type vibration source that vibrating function is provided to above-mentioned person communication system.
Mobile phone in the market can be divided into several types: plate; Flip-type and slide cover type.This class mobile phone is again based on the flip-type mobile phone because the flip-type mobile phone no matter on external form still structurally, perhaps spatially all have than plate mobile phone more superiority.Plate mobile phone is owing to be an integral body on itself structure, therefore it can install cylindrical motor, flip-type then different with mobile phone slide cover type, this is because the direction of vibration of column type motor is vertical vibration, and the direction of vibration of flat type vibration source is a horizontal vibration, if the column type vibrating motor is installed on flip-type and mobile phone slide cover type, can fuselage with cover between cause resonance, thereby can produce vibrating noise.Simultaneously the diameter of the aspect ratio column type vibrating motor of flat type vibration source is little, and it has the more space advantage aspect installation, and it does not have the requirement height of similar cylinder motor on manufacturing process, also has advantage on manufacturing cost.
As shown in Figure 1, flat type vibration source (1A) also claims the button-type vibration source, is an entity that the aspect ratio diameter is little.Flat type vibration source (1A) all is to link to each other with power supply in the communication appliance by lead (85), (83) usually, described lead (85), (83) are again that the mode by welding is connected an end of lead with pad (10), (10A) on the flat type vibration source (1A), described pad (10), (10A) are positioned at flat type vibration source (1A) and stretch out internally and cover on the soft pcb board circuit (9) on lower casing afterbody (20) plane, and the other end is connected with power supply in the communication appliance.Make flat type vibration source (1A) and communication appliance become a complete circuit by this connection.But, owing to be subjected to the influence of the useful space in the communication appliance, it is very difficult that this connection becomes, its reason is that the coverage between two pads (10), (10A) can be above 0.5 millimeter, this is far smaller than the height of pad in the actual welding (10), (10A), if misoperation will cause that the tin between two pads (10), (10A) connects, thereby cause short circuit.Simultaneously, because the diameter of wire that is connected is little and quality is soft, require the employee in practical operation, to take lead on the other hand, take flatiron to weld on the other hand, task difficulty is big, inefficiency, and the defective products that causes thus is high, thereby has directly caused the raising of production cost.
Engineers and technicians have designed a kind of electric connector for this reason, and as shown in Figure 2: described electric connector comprises; A ring-type insulating body (90); The pedestal (95) that links to each other with ring-type insulating body (90).A plane of described ring-type insulating body (90) overlaps and fixes by double faced adhesive tape with flat type vibration source (1A) upper casing.A pair of contact flat spring (92), (87); Described contact flat spring (92), (87) one are " Y " font, and one is " one " font, and have a certain degree and extend to the opposite direction of pedestal (95), and its end face contact point be semicircle (86), (94); The part that contact flat spring (92), (87) other end extend is wrapped up by described ring-type insulating body (90).Two welding endss (93A), (93B): described welding ends (93A), (93B) are positioned at the top of pedestal (95) extension and extend a part to pedestal (95) outside, and parallel with described ring-type insulating body (90).Described two welding endss (93A), (93B) link to each other with above-mentioned a pair of contact flat spring (92), (87) by the interior circuit of pedestal (95) and ring-type insulating body (90), form a complete circuit.Described welding ends (93A), (93B) overlap with pad (10), (10A) that flat type vibration source (1A) lower casing (18) afterbody (20) is gone up (9) on the soft PCB circuit board that extends.
Can see that from above-mentioned accompanying drawing this connector can be installed to specified position fast and get on, thereby improve operating efficiency owing to omitted wire bonds.But also there is some problem; As the fixing of ring-type insulating body (90) and flat type vibration source (1A) upper casing as fixing and unstable, be subjected to temperature bigger, and the accuracy of installation is also inconsistent with artificial influence by double faced adhesive tape.And be installed in the height that ring-type insulating body (90) on flat type vibration source (1A) upper casing has improved whole parts beyond doubt, this change is very unfavorable concerning flat type vibration source (1A), and the original ceiling advantage of flat type vibration source (1A) is disappeared totally.
