Abstract

PURPOSE:To minimize a propagation delay time without a functional reduction by freely rotatably connecting and supporting a connector case holding a printed board side terminal and a connector case holding a contact-side terminal at a connection part. CONSTITUTION:A printed board side terminal 3 fixed to a connector case 1 and a connector side terminal 4 in a connector case 2 are provided to be freely rotatably connected and supported by a connection part 4. And the printed board side terminal 3 of a connector 7 is connected to a printed board 9 and, in a state where the contact side terminal 4 is sloped at a required angle, connected to a printed board 8. The angle of the connector side terminal 4 is set such that the space between the printed boards 9 and 10 becomes minimum. Thereby, the performance of the device is not lowered and high density mounting becomes possible and the propagation delay time of a signal can be minimized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector that can change the connection angle with a printed circuit board.

[Prior Art] Conventionally, this type of connector includes a connector 14 having a contact side terminal 16 and a printed circuit board side terminal 15 provided above and below, as shown in FIG. 5, and a contact side terminal 1 as shown in FIG.
6 and the printed circuit board side terminal 15 are arranged at right angles to each other. There is.

Both of these connectors 14 and 17 had a printed circuit board side terminal 15 and a contact side terminal 16 of an integral structure, and the angle was also unchanged.

[Problem to be solved by the invention] In recent years, with the development of device technology, ICs and LSIs have become more compact and their switching speeds have increased.In order to effectively utilize these, connections within and between printed circuit boards have been improved. The mounting structure has been designed to minimize the length.

Connection between printed circuit boards using the conventional connector 14 is as follows:
This is done by assembling the printed circuit boards 8 to 11 into a three-dimensional mounting structure using the connector 14 as shown in FIG. However, the distance between the printed circuit boards 9 and 10 mounted on a printed circuit board 1 is determined by the dimensions of the printed circuit board 8, so as the dimensions of the printed circuit board 8 increase, the distance between the printed circuit boards 9 and 10 also increases. Connection length increases. As a result, the signal propagation delay time increases, the performance of the device is not effectively utilized, and the performance of the device deteriorates.

On the other hand, in order not to deteriorate the performance, there is a device which uses the connector 17 shown in FIG. 6 and adopts a mounting structure as shown in FIG. 8. However, when the connector 17 is used to narrow the gap between the printed circuit boards 9 and 10, the printed circuit board 8 becomes horizontal, which reduces the number of printed circuit boards 8 that can be mounted on the printed circuit board 9, resulting in a decrease in functionality. .

[Means for Solving the Problems] The present invention has been made in order to solve the above-mentioned conventional problems, and as a means for solving the problems, a printed circuit board side terminal for connecting a printed circuit board held in a negative connector case is provided. and a contact side terminal for connecting a printed circuit board or cable connector, which is connected to the printed circuit board side terminal via a wire and held in another connector case,
The present invention provides a connector characterized in that both of the connector cases described above are rotatably connected and supported by a connecting portion.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a connector according to an embodiment of the present invention, and FIGS. 2 and 3 are sectional views of the connector shown in FIG. 1.

The connector includes printed circuit board side terminals 3 attached to a connector case 1 and contact side terminals 4 inside the connector case 2, as shown in FIG.

The printed circuit board side terminal 3 is used to electrically connect the printed circuit board and to fix the connector on the printed circuit board. As shown in FIG. 2, this printed circuit board side terminal 3 is attached to the connector case 1 with its upper end positioned inside the connector case 1 and its lower end positioned perpendicular to the bottom surface of the connector case 1. There is.

The contact side terminals 4 are used to make contact with other connectors on the printed circuit board, and are installed vertically within the connector case 2 as shown in FIG. Further, the contact side terminals 4 are electrically connected by a wire 6. The contact case 2 that accommodates the contact side terminals 4 is located directly above the connector case 1 and is pivotally supported by the connector case 1 by a connecting portion 5. Thereby, the contact side terminal 4 can be rotated to an appropriate angle as shown in FIG.

Next, an example of mounting a printed circuit board using the connector according to this embodiment will be described.

As shown in FIG. 4, the printed circuit board 9 and 10 are connected to the printed circuit board 11 via the connector 12° 12 with the distance between the printed circuit board 9 and 10 made as small as possible. A printed circuit board 8 on which ICl 3 and the like are mounted is mounted on a printed circuit board 9 shown in the lower part of the figure.

The printed circuit board 8 is mounted on the printed circuit board 9 using the connector 7 of this embodiment as shown. That is, connector 7
The printed circuit board side terminal 3 is connected to the printed circuit board 9, and the contact side terminal 4 is connected to the printed circuit board 8 while being tilted at a required angle. The angle of the connector side terminal 4 is set so that the distance between the printed circuit boards 9 and 10 is minimized. This allows high-density packaging without impairing device performance.

[Effects of the Invention] As explained above, the connector of the present invention has a structure in which the connector case holding the printed circuit board side terminal and the connector case holding the contact side terminal are rotatably connected and supported by the connecting part. The spacing between printed circuit boards can be narrowed, and all necessary printed circuit boards can be mounted.As a result, propagation delay time can be minimized without reducing functionality, and the performance and functionality of the device can be maximized. There is an effect that can be done.
