Description

Exempt from to weld mao button millimeter wave connector

Technical Field

The utility model relates to an electric connector field, concretely relates to exempt from to weld mao button millimeter wave connector.

Background

The millimeter wave connector is widely applied to radio frequency microwave devices, is used for realizing millimeter wave (K wave band and U wave band) connection and conversion between a printed circuit board and a coaxial transmission line, and generally consists of an inner conductor, an insulating medium and an outer conductor; in the prior art, when a millimeter wave band signal is transmitted, the electrical performance of a product can be greatly changed due to the small (0.01mm) size change of the product, and in order to ensure good contact between an inner conductor and a printed board, the existing millimeter wave connector generally adopts two modes: firstly, the inner conductor is welded with the printed board; and secondly, the inner conductor is pressed on the printed board.

When the inner conductor and the printed board are welded together, the size change caused by welding points can bring great changes to the electrical performance of the product, and meanwhile, the device is inconvenient to maintain and replace, and even can be damaged;

when the inner conductor is pressed against the printed board, the inner conductor protruding from the outer conductor must be hard-pressed against the printed board, and the more the inner conductor protrudes, the more reliable the contact is. At the same time, however, more protrusions will result in greater deformation of the printed board, resulting in poorer overall electrical performance.

Disclosure of Invention

To the technical problem, the utility model provides an exempt from to weld mao button millimeter wave connector.

A welding-free fuzz button millimeter wave connector is used for realizing millimeter wave (K wave band and U wave band) connection and conversion between a printed circuit board and a coaxial transmission line and comprises an inner conductor component, an insulating medium sleeved on the inner conductor component and an outer conductor sleeved outside the insulating medium; the inner conductor assembly comprises an inner conductor and a fuzz button; the fuzz button is fixed in a hole at the tail part of the inner conductor, and one end of the fuzz button protrudes out of the end surface of the tail part of the inner conductor and the end surface of the outer conductor; the end surface of the tail part of the inner conductor is not higher than the end surface of the outer conductor.

The fuzz button is an elastic contact body which is woven by elastic metal wires according to a certain method, and signal transmission is carried out by means of elastic contact after the fuzz button is compressed along the axial direction.

When the welding-free fuzz button millimeter wave connector is installed on a printed board, the fuzz button fixed in the tail hole of the inner conductor is compressed to be flush with the end face of the outer conductor, abuts against the printed board by means of elasticity of the fuzz button millimeter wave connector and is in reliable contact with the printed board.

The utility model has the advantages that: through the hair button arranged in the end face hole of the inner conductor, stable elastic pressure contact between the inner conductor and a printed board circuit is realized, good contact is guaranteed, the printed board circuit and mechanical deformation are not caused, and the electrical performance of the product is effectively improved. Meanwhile, the inner conductor and the outer conductor of the welding-free fuzz button millimeter wave connector are connected with the printed board without adopting a welding mode, so that the assembly, the disassembly and the maintenance are very convenient.

Drawings

The present invention will be further described with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an overall structure of a welding-free fuzz button millimeter wave connector;

FIG. 2 is a schematic view of an installation of a solderless fuzz button millimeter wave connector;

in the figure: 1 insulating medium, 2 outer conductor, 3 inner conductor, 4 hair button and 5 printed board.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, a welding-free fuzz button millimeter wave connector comprises an inner conductor assembly, an insulating medium 1 sleeved on the inner conductor assembly, and an outer conductor 2 sleeved outside the insulating medium 1; an insulating medium 1 and an outer conductor 2; the inner conductor assembly comprises an inner conductor 3 and a fuzz button 4; the fuzz button 4 is fixed in a hole at the tail part of the inner conductor 3, and one end of the fuzz button 4 protrudes out of the end surface of the tail part of the inner conductor 3 and the end surface of the outer conductor 2; the end surface of the tail part of the inner conductor 3 is not higher than the end surface of the outer conductor 2.

As shown in fig. 2, when the solderless fuzz button millimeter wave connector is mounted on the printed board 5, the fuzz button 4 fixed in the hole at the tail part of the inner conductor 3 is compressed to be flush with the end face of the outer conductor 2, and is propped against the printed board 5 by means of the elasticity of the fuzz button millimeter wave connector to be reliably contacted with the printed board 5.

The utility model provides a exempt from to weld hair button millimeter wave connector is through at 3 afterbody downtheholess installation high-accuracy elastic component hair button 4 of inner conductor, realized inner conductor 3's stable pressure contact, can not arouse printed circuit board circuit and mechanical deformation when guaranteeing the good contact of inner and outer conductor, very big improvement has been had to product electrical property, especially more obvious in the U wave band, almost improved one time on original basis, stability and uniformity have also increased substantially, the contact of hardly because of inner conductor appears product electrical property's unstability and inconsistent.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
