Realize the printed wiring board test connector of fast insert-pull.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of printed wiring board test connector, including
Inner wire, outer conductor and insulator, the outer conductor have hollow cavity, and insulator and inner wire are placed in outer conductor
In cavity body, inner wire is dielectrically separated from by insulator and outer conductor, and the inner wire includes the first inner wire and is inserted in the
The second inner wire in one inner wire, the first inner wire, which embeds, is cased with spring, and one end of spring is connected on the first inner wire, separately
One end is connected on the second inner wire.
Avoid coming off further for the stroke of the second inner wire of limitation, led on first inner wire in second
One end tight fit of body has the 3rd inner wire, and second inner wire has bar portion and end, and the 3rd inner wire is sleeved on described
In bar portion.
Further, the end press-fitting of the outer conductor has with being led outside the matched elasticity of aperture in printed wiring board
Body.
After employing above-mentioned technical proposal, by elastic outer conductor be inserted into printed wiring board on aperture, the second inner wire by
To extruding, spring contraction, the second inner wire is abutted on a printed-wiring board, so as to ensure second under the action of spring-return power
The close contact of inner wire and printed wiring board, makes connection more stable and reliable；Inner wire is designed to double-body bike by the present invention, and
Centre sets spring, it can be achieved that the second inner wire is flexible up and down, so as to ensure its contact with the copper strips in printed wiring board；Outside
One end of conductor sets elastic outer conductor, so as to ensure that outer conductor is in close contact with printed wiring board；The configuration of the present invention is simple can
Lean on, can realize fast insert-pull and stable connection, be especially suitable for the electric performance test of printed wiring board and device interface.
