Device.
Background technology
The cylindrical connector of in the market mass selling, simply it is only capable of connecting the ordinary connector of signal or power supply.Connecting
Installing electric capacity on device additional makes it become a special joining device, and method is to install one additional outside the bonding wire end of connector greatly earlier
Electric capacity, this mode are that method is simple, easily operation, and cost is low, and shortcoming is the increase in product weight and volume.And because it is
Easily there is seam, make signals leakiness toward docking together in two kinds of products.Practical function is bad.Closely during the last ten years, market is again pottery
Porcelain tube formula electric capacity introduces connector.Ceramic pipe type condenser welding is on the contact pin in connector, make connector do not change volume and
Under profile and weights, filter function is realized, but for the small space in earthenware opposing connector, volume is a little
Greatly, and must ground copper need the groove of connector inwall one 1 mm wide of car, this is in the market of product miniaturization
In be impossible to accomplish.That is, a lot of small-sized connectors are can not to realize filtering by installing ceramic pipe type electric capacity additional
Function.Especially ceramic pipe type electric capacity is enclosed on the contact pin in connector, and contact pin is copper, the receipts of both materials
