Description
The present invention relates to a kind of adapter and manufacture method thereof, refer in particular to the telecommunication conducting between a kind of different size electric connector of realizing distinct electronic apparatuses, and can realize the adapter and the manufacture method thereof of good ground connection and shield effectiveness.
For realizing the telecommunication transmission between the distinct electronic apparatuses, the electric connector on two electronic equipments electrically need be connected in series usually.When the electric connector specification was identical, the electric connector on the distinct electronic apparatuses can directly dock; When the electric connector specification is different, then usually need to utilize an adapter that it electrically is connected in series, in the environment of high speed, high frequency, this adapter must have good shielding and the ground connection effect could realize good telecommunication transfer function.
Early stage adapter is with flat cable or lead two adaptor connectors to be coupled together, but the function of shielding and ground connection is not provided.After this, the design of two adaptor connectors has appearred again connecting by circuit board, it adopts tinplate to strike out the shield member of cover cap shape to realize function of shielding usually, the Taiwan patent application promptly discloses this prior art No. 82206792, as shown in Figure 1, adapter 6 includes two adaptor connectors 60,61, the circuit board 62,63 of realizing electric connection between two adapters 60,61, metallic shield lid 64 and outer cover 65.Two adaptor connectors 60,61 adopt the longitudinally deploying, and metallic shield lid 64 adopts tinplate to strike out the cover cap shape, and its two ends are equipped with some contact feets 641 and fastening piece 642.During assembling, two metallic shields lid 64 fastens the outside that is coated on circuit board 62,63 by fastening piece 642, and contacts the metal shell of adaptor connectors 60,61 by contact feet 641, thereby realizes the function of shielding and ground connection.Though this shielding mode is easy to assembly, simple in structure, this two-piece type screening cover can produce the phenomenon of poor sealing, causes shield effectiveness relatively poor, moreover because the tinplate price is higher, also can increase the cost of adapter.
When the deploying mode of this kind adapter is changed into the deploying of " Z " font from the longitudinally deploying after, just produced more shortcoming.Another Taiwan patent that the applicant of present patent application applied on March 31st, 2000 has promptly disclosed the correlation technique of this deploying mode, and this patent still is in inspection phase, and its application number is 88121901A01 number.As shown in Figure 2, adapter 7 comprises adaptor connector 70,71, connects the circuit board 72 and the shell 75 of two adaptor connectors 70,71, and shell 75 adopts ejection formation.This adapter is if still take tinplate to strike out the shielding construction of cover cap shape, and its shortcoming is quite obvious, because the restriction of the shape of adapter makes the two-piece type screening cover be not easy driving fit, and also needs between the cover cap to add retainer in addition, so shield effectiveness is not good; In addition, because the shell of this adapter adopts ejection formation, so pressure in the time of need resisting ejection formation by the rigidity of tinplate, again because the terminal supportor 73,74 of adaptor connector 70,71 stretches out switching circuit board 72, therefore the moulding meeting for shell causes difficulty, and shielding construction is difficult for close transition circuit board 72 and terminal supportor 73,74, in addition when the ejection formation shell, the pressure of its generation may make the inside bending of shielding construction, then might touch terminal supportor 73,74 and the formation short circuit; Again just like more expensive with the described because tinplate price in front and need die sinking in addition when making, so cost is higher, and economy is not good.
Therefore, be necessary to provide a kind of manufacture method of adapter, to solve the above problem that is faced.
The purpose of this invention is to provide a kind of manufacture method that is used to realize the adapter of telecommunication conducting between the electric connector on the distinct electronic apparatuses.
Another object of the present invention provides a kind of manufacture method that realizes the adapter of good shielding and ground connection effect.
The objective of the invention is to realize by following technical step: (1) prunes the conducting terminal of electric connector, when making electric connector be installed on the switching circuit board, its conducting terminal pin front end flushes with apparent surface away from the switching circuit board on surface, connector place, and electric connector is welded on the switching circuit board; (2) attach dielectric isolation layer in the welding portion position of switching circuit board, and dielectric isolation layer covers whole solder joints; (3) the connecting portion clad metal screen of welding portion and electric connector on switching circuit board; (4) boxing metal screen layer and make the screen of welding portion on the switching circuit board and the screen of electric connector connecting portion electrically connects; (5) profile that ejaculation type adapter is required.
Compared with prior art, the advantage of manufacture method of the present invention is: can realize the shielding and the grounding function of adapter effectively, and any profile variation of adapter manufacture method of all not influencing shield member with and the shielding and the ground connection effect that are realized.
