Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-pole crimp connector, and particularly to a multi-pole crimp connector for flat display devices such as plasma display panels and liquid crystal panels.

Various types of display devices have been proposed.

Among them, the planar shape has the advantage of being smaller, so
Their development is progressing, and plasma display panels, for example, are advantageous in that they have a memory function.

In such flat display devices, it is desired that the means for connecting them to peripheral circuits be simple and inexpensive.

For example, in a plasma display panel in which a plurality of electrodes are provided on a substrate in each of the X and Y directions and are faced to each other with a discharge gas space in between, as shown in FIG. Generally, this terminal is connected to, for example, a flexible lead 3, and connected to peripheral circuits via the flexible lead 3.

However, since the terminal spacing is narrow, it is not easy to connect the flexible leads, and the mechanical strength is not sufficient.

Furthermore, the flexible lead 3 has the disadvantage of being expensive.

FIGS. 2a to 2c are cross-sectional views for explaining conventional connection means, and FIG. 2a shows the terminal 1a on the board 1 and the flexible connector. This shows a case where a lead wire 3a such as a lead is connected with a conductor 4 such as solder or silver paint, and reinforced with a synthetic resin layer 5, and when the lead wire 3a is a flexible lead covered with an insulating layer. In this case, it is not easy to remove the insulating layer for connection, and as mentioned above, the soldering work is not easy.

FIG. 1B shows a case in which a connector 6 is used, in which the contact pieces 6a come into contact with the terminals 1a while sandwiching the board 1, and are connected to peripheral circuits by lead wires or connecting pins 6b.

However, connectors with this configuration have the advantage of not requiring soldering and are easy to connect and disconnect when the number of pins is relatively small, but when the number of pins is large and the pinch is small, it is not reliable. It is not easy to make the connection.

Also, Figure C shows a crimp connection between the terminal 1a on the board 1 and the lead wire 3a by tightening the frame plates 1 and 8 with screws 9, and it is relatively easy to attach and detach as in the case of a connector. However, since the contact between the terminal 1a and the lead wire 3a is made by applying pressure to avoid applying uneven stress to the substrate 1, such as glass, great care is required to ensure a reliable pressure contact. .

The present invention is a novel invention that improves the conventional drawbacks as described above, and its purpose is to connect a flat display device in which a large number of terminals are led out on a substrate at minute intervals and its peripheral six-sided circuit. ,
It is an object of the present invention to provide an inexpensive multi-pole crimp connector that can be connected reliably and easily.

Examples will be described in detail below. FIG. 3, FIG. 4, and FIG. 5 are explanatory diagrams of one embodiment of the present invention, and in a flat display device such as a plasma display panel,

By alternately arranging these two types of connection pieces 12, including those with different lead-out positions for each cV,
The connecting portions 12b are led out in a staggered manner.

Therefore, connection to peripheral circuits by wrapping, soldering, etc. is facilitated.

2b and 15b can be inserted into a printed board and connected by soldering or the like, or by wrapping lead wires around the connecting portions 12b and 15b, connections with peripheral circuits can be made.

As mentioned above, in this embodiment, the elastic force of the connecting pieces 12 and 15 and the tightening pressure between the upper frame 10 and the lower frame 13 are used to make crimp connections with the terminals on the substrates p 1 and P 2 , resulting in an expensive Reliable connection is possible without using flexible leads.
