Abstract
The invention discloses a printed circuit board test connector. The printed circuit board test connector comprises an inner conductor, an outer conductor and an insulator, wherein the outer conductor is provided with a hollow cavity; the insulator and the inner conductor are arranged in the hollow cavity of the outer conductor; the inner conductor is isolated from the outer conductor by the insulator; the inner conductor comprises a first inner conductor and a second inner conductor which is inserted into the first inner conductor; a spring is nested in the first inner conductor; one end of the spring is resisted against the first inner conductor; and the other end of the spring is resisted against the second inner conductor. The printed circuit board test connector is simple and reliable in structure, and capable of realizing quick insertion and extraction, and connecting stability.
Description
Technical field
The present invention relates to a kind of radio frequency (RF) coaxial connector, be specifically related to a kind of printed substrate test connector.
Background technology
In communication system, a lot of passive device inside has a lot of printed substrate circuit, plate can be reserved porose and copper strips for solder connector, after a lot of, add-in connectors is all nonstandard connector, or leave equipment vendor for go to install, when carrying out the electrical property pretest of printed substrate and device interface, test connector will weld on a printed-wiring board usually, to realize the connection with printed substrate, this method is difficult to realize fast insert-pull, and connection reliability is poor.
Summary of the invention
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provides a kind of and can realize the printed substrate test connector of fast insert-pull with printed substrate.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of printed substrate test connector, comprise inner wire, outer conductor and insulator, described outer conductor has hollow cavity, insulator and inner wire are all placed in the hollow cavity of outer conductor, inner wire is insulated by insulator and outer conductor and isolates, described inner wire comprises the first inner wire and is inserted in the second inner wire in the first inner wire, first inner wire has been nested with spring, one end of spring is connected on the first inner wire, and the other end is connected on the second inner wire.
Stroke further in order to limit the second inner wire is avoided coming off, and one end tight fit near the second inner wire on the first described inner wire has the 3rd inner wire, and the second described inner wire has bar portion and end, and the 3rd inner wire is enclosed within described bar portion.
Further, the end of described outer conductor is press-fitted the elasticity outer conductor matched with the aperture on printed substrate.
After have employed technique scheme, elasticity outer conductor is inserted the aperture on printed substrate, second inner wire is squeezed, spring contraction, under the effect of spring-return power, the second inner wire abuts on a printed-wiring board, thus ensure the close contact of the second inner wire and printed substrate, make connection more reliable and more stable; Inner wire is designed to double-body bike by the present invention, and arranges spring in centre, can realize the second inner wire and stretch up and down, thus ensure the contact of the copper strips on itself and printed substrate; One end of outer conductor arranges elasticity outer conductor, thus ensures outer conductor and printed substrate close contact; The present invention is simple and reliable for structure, can realize fast insert-pull and stable connection, is especially suitable for the electric performance test of printed substrate and device interface.
