Description

The coaxial cable connector

Technical field

A kind of coaxial cable connector refers to that especially mode that terminal in a kind of terminal base penetrates with inserts embeds the connector of glue core.

Background technology

Science and technology is maked rapid progress, the variation of product design also more and more is difficult to imagination, but change a trend is always arranged, and an important trend dimensionally, that is exactly that weight is lighter, thickness is thinner, length is shorter, size is littler, but four above-mentioned big emphasis, but with the variation of work function, mechanism complicated and more augment difficulty.In communications industry, coaxial connector is a connector that often is used in the mobile phone, since the mobile phone of a new generation be required to have only several centimeters less than thickness, therefore the various electric connectors that wherein used also are forced to microminiaturization, so its project organization also produces greatest variation.

A kind of coaxial connector that has been disclosed, as No. 01125198.0, Chinese patent, comprise first resin piece, second resin piece, metal fixed terminal, removable terminal and outside terminal, this first resin piece has a female parts, the center sub of corresponding coaxial connector inserts this female parts, and this second resin piece and first resin piece constitute insulation crust, and fixed terminal and removable terminal are sandwiched between between first and second resin pieces.For allow fixed terminal and removable terminal between first and second resin piece, reach advantages of good positioning effect, fixed terminal and removable terminal are provided with semi-circular indentation, the plush copper of one of them resin piece is used to pack into, soldering tip with welder is pressed into cheese with adhesive fixedly fixed terminal and removable terminal with each plush copper weldering again, another resin piece then is provided with and the corresponding rounding of cheese top connected in star, so that first resin piece and second resin piece can corresponding combinations, this kind structure and assembling mode, though increased fixed terminal and the removable terminal fixedly precision between first resin piece and second resin piece, but the flow process and the time of making assembling have also been increased, in fact when soldering tip welds the plush copper of pressurizing resin spare, if producing, moves terminal, even be small skew, after the weldering pressure is finished, the soldering tip melt that is out of shape because of temperature has made the skew of terminal fix, and this point has also caused the lifting of product fraction defective.

Because the size of this coaxial connector is very small, in welding, weldering slurry and flux can be inhaled between first resin piece and second resin piece because of siphonage, though this coaxial connector is provided with the groove of V-arrangement cross section in resin piece, to prevent that weldering slurry and flux from infiltering in the insulation crust, but the size of therefore planting connector is very small, and the deal of weldering slurry and flux is difficult to be controlled at and can never makes weldering slurry or flux infiltrate insulation crust.

Moreover this outside terminal is to cover the chucking insulation crust with the leg on four angles, and meaning i.e. this connector need be controlled the precision at four angles that bend, and this connector contacts with PCB with four angles, more easily produces bad on the flatness.
