Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a connector with a shield electrode mainly used in electronic computers and communication equipment, and particularly to improvements in the structure of the shield electrode.

fbl Technology Background Computers and communication equipment are becoming increasingly faster and more compact in recent years, and related electronic components are also required to be suitable for high-density packaging.

The connectors that removably connect a large number of circuit blocks of the electronic equipment described above are also becoming more densely packed.

tel Conventional Technology and Problems As the circuit packaging of electronic devices becomes more dense, it is becoming increasingly difficult to prevent noise disturbances caused by electrical interference between circuit wiring and external circuits from adversely affecting the operation of the electronic devices. Ta.

Therefore, in multi-element connectors, noise is suppressed by using a method in which, for example, the terminals on both sides of one signal terminal are grounded terminals, and signal terminals are arranged every other terminal. A part of the connector terminal is used as a ground terminal, which goes against the trend toward higher density, and the electrical shielding is insufficient.

In addition, as shown in FIG.
1 (or jack terminal), there is an example in which the seal 1 and the electrode 2 are individually interposed between the shield electrodes 2, but the structure of the connector becomes complicated because the shield electrodes 2 are connected to each other.

This has the disadvantage of increasing the number of steps required for connection.

(di) Purpose of the Invention The present invention has been made in view of the above-mentioned points, and provides an improved structure capable of electrically shielding each connecting terminal of a connector having a plurality of sets of connecting terminals from each other effectively and inexpensively. The purpose of this invention is to provide a unique shield electrode.

tel Structure of the Invention An object of the invention described above is to provide a shield electrode formed of a continuous meandering metal plate on either one of the connector jack and the connector jack. and a plurality of housings each comprising a plurality of plug terminals and a jack terminal for conveying electrical signals on the connector plug and the one-way connector socket, respectively, and holding the plug terminal, jack terminal, and shield electrode at predetermined positions, respectively. and has a structure in which each set of terminal combinations constituted by each of the plug terminal and jack end A is individually partially surrounded by the shield electrode.

Furthermore, this can be easily achieved by using a shield electrode connector characterized in that it has means for connecting the seal 1 electrode to ground potential.

(“) Examples of the invention Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows an embodiment in which the present invention is applied to the conventional sole-equipped connector plug having one row of terminals shown in FIG. As can be easily seen in the figure, conventional individual shield electrodes 2
is one shield electrode 2a formed from a corrugated metal plate.
has been replaced by The electrodes are easy to manufacture, and it is also easy to incorporate them into the connector. Of course, the structure of the mating connector jack is also changed to correspond to the connector plug. These details will be omitted and will be explained in detail in the case of a two-row terminal arrangement described below.

FIG. 3 shows a layout diagram in which the continuously meandering shield electrode according to the present invention is applied to connectors with various terminal arrangements. If the terminal arrangement is two or more rows, it is possible to solve the problem by using only the continuous meandering shield electrode described above, but it will become more complicated than lightning, so divide the shield electrode into two and use the shield electrode jack part 3 and the shield electrode plug. It is extremely convenient to combine it with section 5. Figure 3 (a) is the same as section 1 shown in figure 2.
1 seat 1 child arrangement of the column, (bl shows the 2 row terminal arrangement of the base grain type, ((old) shows the 2 row terminal arrangement of the staggered pattern, (d) shows the 3 row end r arrangement of the base grain type, respectively. , is an explanatory diagram of a method in which a shield electrode plug section 5 is also used.

5. As a specific structural example, let us explain a staggered connector with two rows of terminals (FIG. 3(C)).

FIG. 4 is a perspective view showing only the terminal structures on the plug terminal side and the jack terminal side of the connector and showing the main parts of an embodiment based on the present invention for an explanation terminal arrangement.

On the connector plug side, in addition to the conventional plug terminal 1, there is a meandering continuous shield electrode jack part 3 as shown in the figure.
are arranged between the plug terminals 1 so as to separate them from each other, and in the case of FIG. 9, a slit 3a is formed exactly at the center of the height of the shield electrode jack portion 3.

In addition, 3b is a grounding terminal that directly grounds the seal 1'' electrode seat 3 when the ground potential of the seal 1 electrode is not taken from the connector plug side rather than from the connector plug 1 rule, as will be described later. It is.

On the connector jack side, a flat shield electrode plug portion 5 is provided outside the conventional seat-tock terminal 4 (not shown). The shield electrode plug part 5 is provided with a tongue-shaped plug contact part 5a that corresponds precisely to the slit 3a of the mating shield electrode jack part 3, and when connecting the connector plug and the connector jack. The seal (-plug contact portion 5a of the electrode plug portion 5) is inserted into the slot 3a of the shield electrode jack portion 3 and electrically connected, forming an electrical shield electrode.

The actual structure of the connector explained in Section 2 is conceptually explained in Section 5.
Shown in cross-section in the figure.

The connector plug connects the plug terminal 1 with the meandering seam.
The lead electrode jack part 3 is assembled into the synthetic resin housings 6 and 7 of the synthetic resin housing 8 and the flat plate-shaped The shield electrode plug part 5 is made of synthetic resin housing! 1. It is composed of 1+1.

A multi-element flat cable housing 9 and IO are fixed to the connector jack, and the signal line 118 is connected to the jack terminal 4. Ground wire 11
b is connected to the shield electrode plug 81-5.

Therefore, when a connector plug is inserted into a connector jack and connected, the jack terminal 4 and the plug terminal 1 are electrically connected as in a regular connector, and transmit electrical signals. The shield electrode plug part 5 and the shield electrode jack part 3 are integrally connected to the grounding wire 11b of the cable.
The FD open circuit is connected as a shield electrode to electrically shield it from the outside.

In the embodiment shown in Section 4 and 1, one plug terminal is accommodated in each meandering section of the shield' electrode jack section 3 (as schematically shown in the terminal arrangement diagram (C) in the figure). Ori.
In terms of electrical shielding, the seal 1-electrode plug part 5 is not necessary and merely serves the function of connecting to the ground wire of the cable. As shown in Figure 3 [b), fd), if the terminal arrangement of the connector is not staggered, it is clear from the figure.

It can be seen that the electrode plug part 5 of the seal 1 maintains the ground potential of the cable and is effective for electrical shielding.

The features that are common to the structure of the shield electrode described above are as follows.

Both have a continuous terminal structure and are made by punching out a highly elastic and conductive metal plate such as phosphor bronze using a press die.

This means that it can be press-formed using a bending die and can be easily delivered prematurely.

In the embodiment of the present invention shown in FIG. 5, the shield electrode plug part and the shield electrode jack part are respectively disposed on the plug side and the jack side of the connector. It is obvious that the above combination may be reversed, as will be easily understood upon consideration.

(g) Effects of the invention As is clear from the above explanation, the shield electrode of the shield electrode I' connector according to the present invention
If this method is adopted, both the plug and jack parts of the shield electrode can be formed using sheet metal processing from metal plates at ill+N/i degree and at low cost, and the assembly of the connector becomes easy. There are significant benefits in improving the reliability and reducing cost of the 1-1 connector with Li pole.
