Abstract

PURPOSE:To obtain a connector which has the same function as that of a coaxial contact and a smaller size by storing male and female connectors in insulating material molded frames which have respective spaces inside and have the overall wall faces given conductive plating. CONSTITUTION:Insulating frames 2, 5 have spaces 2a, 5a formed inside and have the overall wall faces given conductive plating. A connector consists of male and female connectors 1, 4 that insulators 8 supporting male and female contacts 6 shaped the same as the spaces 2a, 5a are pressed into the frame 2. The arrangement is made in order that when both connectors are fitted, the contact portion 3a of the male contact has contact with the contact spring 6a of the female contact for electrical connection. This is fitted to a printed board 7 to connect the frames 2, 5 to an earth circuit on the board 7 via a terminal 9. It is thus possible to shut off the contact from the other adjacent contact at earth potential, provide the same function as that a coaxial connector and form the connector without increasing its size.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector having a function similar to that of a coaxial connector.

0002

Conventionally, this type of connector has a structure in which a conductive male contact and a conductive female contact are press-fitted into a set of insulators molded into a predetermined shape. There is.

[0003] Such a connector will be explained using figures.

FIG. 4 is a sectional view of a conventional male connector and female connector in a fitted state, FIG. 5 is a perspective view of the female connector, and FIG.
is a perspective view of a male connector.

As shown in the figure, a male contact 53 is housed in an insulator 52 of a male connector 51 by a method such as press-fitting, and a female contact 56 is similarly housed in an insulator 55 of a female connector 54 by a method such as press-fitting. accommodated by the method. One end of the male contact 53 is connected to the female contact 56.
It is configured as a contact portion 53a that electrically and mechanically contacts a contact spring 56a formed at one end of the contact spring 56a. Further, the other ends 53b and 56b of the male contact 53 and the female contact 56 protrude from the insulators 52 and 54, respectively.
It is inserted into a through hole formed in the printed circuit board 57 and connected by soldering.

However, in the conventional connector described above, since adjacent and opposing contacts are separated only by an insulator, it is difficult to transfer high frequency electrical signals due to crosstalk.

Furthermore, if it is preferable to use a coaxial connector to transfer high-frequency electrical signals, it is difficult to miniaturize the coaxial connector to the same terminal pitch as a conventional connector, and even if it were possible, it would be expensive. Currently, it has not been put into practical use due to the price.

[0008] An object of the present invention is to provide a miniaturized connector that has the same functions as a coaxial connector.

[0009]

[Means for Solving the Problems] The connector of the present invention has a frame molded from an insulating material, forming a space therein, and having conductive plating applied to the inner and outer wall surfaces,
A male connector and a female connector are provided, each of which is configured by accommodating an insulator holding a conductive contact in a space formed in the frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of the present invention.
A state in which the male connector and female connector are mated is shown. FIG. 2 is a perspective view of the female connector, and FIG. 3 is a perspective view of the male connector.

Frame 2 of male connector 1 and female connector 4
The frame bodies 5 are each formed into a predetermined shape from an insulating material, such as a synthetic resin material. A plurality of spaces 2a, 5a having predetermined shapes and dimensions are formed inside these frames 2, 5. Also spaces 2a, 5
Conductive plating is applied to the entire wall surface of the wall a and the outer wall surfaces of the frames 2 and 5. As this conductive plating, there are methods such as electroless plating and electrolytic plating after electroless plating, and any method can be used.

The male contacts 3 constituting the male connector 1 and the female contacts 6 constituting the female connector 4 are formed in the same shape as the spaces 2a and 5a formed in the frames 2 and 5, respectively, and are It is supported by an insulator 8 molded with slightly larger dimensions than 2a and 5a. Then, by press-fitting the insulator 8 supporting the respective contacts 3 and 6 into the frames 2 and 4, the male connector 1
and a female connector 4.

One end of the male contact 3 facing the female connector 4 is formed as a contact portion 3a, and the other end 3b is formed to protrude from the frame 2. . Further, one end of the female contact 6 facing the male connector 1 is provided with a contact spring 6a having spring properties, and the other end 6b is formed to protrude from the frame 5. has been done. Therefore, when the male connector 1 is fitted to the female connector 4, the contact portion 3 of the male contact 3
a contacts the contact spring 6a of the female contact 6 and is electrically
It is possible to connect mechanically.

In order to attach the male connector 1 and female connector 4 configured as described above to the printed circuit board 7, the ends 3b and 6b of the male contact 3 and the female contact 6 are respectively inserted into through holes formed in the printed circuit board 7. It can be attached and fixed by soldering.

The frames 2 and 5 of the male connector 1 and female connector 4 attached to the printed circuit board 7 are connected to a ground circuit provided on the printed circuit board 7 via terminals 9. Therefore, it becomes possible to disconnect each contact 3, 6 from the other adjacent contacts 3, 6 at the ground potential.

[0017]

As explained above, the present invention provides a connector in which contacts are held by an insulator and this insulator is housed inside an insulating frame whose wall surface is conductive plated. Therefore, by attaching this connector to a printed circuit board and connecting the frame to a ground circuit, each contact can be cut off at ground potential. Therefore, it is possible to achieve the same function as a coaxial connector, and it has the effect that high frequency electrical signals can be exchanged without increasing the size of the connector.

Another advantage is that the characteristic impedance can be easily set by appropriately setting the shape and dimensions of the contact, the inner diameter of the space formed inside the frame, the dielectric constant of the insulator supporting the contact, etc. There is.
