Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In conjunction with shown in Fig. 1 to Fig. 4, be the utility model one preferred embodiment, a kind of pick-up unit based on PCB radiofrequency signal, comprises shell 1 and inner wire 2, shell 1 is sheathed on inner wire 2.Inner wire 2 comprises insulating element 21, female part 22 and probe 23.Shell 1 is set on insulating element 21, female part 22 is interspersed in insulating element 21, and probe 23 is interspersed in shell 1, and insulating element 21, female part 22 and probe 23 form enclosed construction, electromagnetic field is limited between female part 22 and insulating element 21, thereby has avoided radiation loss.
Concrete, probe 23 is five, and one of them probe is interspersed in female part 22, and all the other four probes are interspersed in shell 1 and are fixed on shell 1.Female part 22 adopts resilient beryllium-bronze to make, and the oral area of the port of female part 22 is oval.In the time making, after dimensioned is complete, close up at port, make oral area become ellipse, then thermal treatment, makes oral area sizing, can make like this insertion force of probe 23 softer, and the life-span of female part 22 is longer.
Shown in Fig. 4, probe 23 comprises movable part 233, fixed part 231, package parts 232, sharp-pointed joint 234 and spring (not marking in the drawings).Spring is placed in fixed part 231, and movable part 233 embeds in fixed part 231 and is connected on fixed part 231 by spring.Package parts 232 cover in one end of fixed part 231, and spring is encapsulated in fixed part 231.Contact with tested wiring board contact with the probe 23 of spring owing to adopting, can protection circuit plate be subject to the impact of external force.Sharp-pointed joint 234 is fixed on one end of movable part 233, and sharp-pointed joint 234 adopts the mode with tin contact of thrusting tested wiring board to be connected with tested wiring board.Adopt sharp-pointed joint 234 to thrust in the contact with tin, thereby ensured that probe 23 can reliably be connected with wiring board.
Shell 1 is connected by the mode of a riveting with probe 23.With putting uniformly riveting in the position that special tooling is installed probe 23 on shell 1 surface, the pick-up unit having assembled, can ensure to be connected with probe 23 reliably, can ensure that again probe 23 easily dismantles, so that change the probe of other type, increase the serviceable life of pick-up unit, reduced client's cost.On shell 1, offer embedding mouth 3, shell 1, insulating element 21 and female part 22 are fixed by epoxy resin, and epoxy resin carries out embedding from embedding mouth 3, as shown in Figure 1.
