Abstract
A sensor connector is combined by a high-density flexible connector and a hollow flexible insulating sealing material. A certain number of conductive mental wires or conductive microspheres are arranged inside the high-density flexible connector, wherein the mental wires are mutually insulated through a silica gel. Pressure is applied between the sensor and a circuit board, and tight fitting among the circuit board, the novel connector and the sensor can be realized through pressure contact, and transmission of electrical signals, environmental sealing of the circuit pins and environmental sealing of a sensing interface are realized. With the novel connector provided by the utility model, the connection structure of the sensor and the circuit board is simpler, the circuit board is simplified, and assembly and sealing techniques of the sensor are optimized, and when something is wrong with the sensor, the disassembly is convenient and the replacement is easy.
Description
Affiliated technical field
The utility model relates to the new technique field of transducer, is specifically related to a kind of novel connector and is used for being connected of transducer and circuit board.
Background technology
At present, common transducer is that gold thread is perhaps broken aluminum steel and circuit board welds through beating, but welding is not firm, problems such as rosin joint, crackle, pore, slag inclusion can occur.If the signal that transducer need transmit is many, itself and circuit board need routing a lot, make structure complicated, and technological requirement is high, and cost increases.Because circuit board is the side that is welded on transducer, it is big that occupation space becomes.Common transducer is connected with circuit board, in case occur damaging, owing to, be difficult for changing in fact through what be welded to connect.In addition, sensor electrical signal coupling part receives outside contamination easily, can cause the electric signal noise to raise, and will consider extra Seal Design usually.Moreover; Many transducers need be to the interface of sensing seal protection in addition; Its sensing interface can not receive the interference (such as being applied in pressure, biology, the top transducer of chemistry) of external environment; Therefore the sealing that needs will be got well (we claim environmental sealing the sealing here), and common transducer is to guarantee sealing through sealing ring or fluid sealant fitted seal technology.But above-mentioned encapsulating method has increased the complexity to other technical process of transducer, influences sealing reliability easily.
Summary of the invention
To use traditional welding technology connecting circuit plate and transducer in order solving, the transmission of electric signals that brings, to seal problems such as unreliable, the utility model provides a kind of novel connector that is used in transducer.This product need not welding, when guaranteeing the reliable transmission signal of telecommunication, has guaranteed the sealing of electric signal coupling part and the sealing at sensor sensing interface, and has greatly reduced the manufacturing complexity of transducer.
The utility model solves the technical scheme that its technical problem adopted: a kind of sensor connector is provided; Be used for carrying out being connected of circuit board and transducer; Soft encapsulant by soft connector of high density and hollow combines this novel connector and circuit board and the tight pressing of transducer.
Preferably, the structure of the soft connector of said high density is to pass the conductive wire or the metallic microspheres of some in the middle of the block soft insulating material, and conduction is to lean on these wires or the metallic microspheres that contacts with each other is realized.
The beneficial effect of the utility model is: can avoid problems such as rosin joint that solder technology causes, bridge joint; The syndeton of transducer and circuit board is simpler, and the space occupancy of circuit board is reduced, and optimizes the packaging technology of transducer; Transducer goes wrong, and easy accessibility is prone to change; Sealing technology is simple, and sealing medium is integrated in the novel connector.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sectional view that the utility model is used for transducer
Fig. 2 is the vertical view of the utility model connector
Fig. 3 is the sectional view of the soft connector of the utility model middle-high density
Among the figure, the soft connector 3. transducer conductive contacts of 1. soft encapsulant 2. high density 4. transducers 5. circuit boards 6. soft insulating material hollow spaces (can be made into difformity according to demand) are conductive wire or conductive micro-balloons 9. soft insulated parts in 8. connectors of sensor sensing interface 7.
Embodiment
In Fig. 1; The soft connector of circuit board 5, soft insulating material 1, high density 2, sensor contact district 3, transducer 4 as figure connect; When signals such as chemistry, biology, pressure got into sensor sensing interface 7 through breach 6, transducer got an electric shock signal and distinguishes 3 outputs from transducer, be transferred to circuit board 5 through soft connector 2; Circuit board that soft encapsulant is tight and top and following transducer; Mechanical force guarantees fitting tightly of top and bottom, thereby guarantees sealing, has strengthened the accuracy of transducer.
In Fig. 2, soft encapsulant 1 has been realized environmental sealing, prevents the interference of extraneous environment.
In Fig. 3, conductive metal wire or metallic microspheres 8 are accomplished the signal transmission, and soft insulating material 9 guarantees and the applying degree of top and bottom that conduction is reliable.
