Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting plate used for connecting printed wiring boards, for example, and particularly to a connecting plate suitable for connecting connectors provided at one end of printed wiring boards.

In the case of connecting the pins 4 of the same bin number of the adjacent connectors 4 by winding the electric wire 6 around each connector bin 5 and connecting the pins 4 of the same bin number of the adjacent connectors 4, as shown in FIG. This is done by winding the electric wire 6 around the attached post 3b of the connection plate 7 and soldering it.

Each boss) 3b is made of the same material and is integrated into a connecting plate 7 made of an insulating material.

FIG. 1 is a diagram showing a state in which a conventional connecting fitting is attached to a wrapping post. The structure of the connecting fitting is such that the attachment fitting 2 is attached to the seat 1 by caulking.

Attachment to the wrapping post is done by passing the wrapping post through a cutout hole in the upper part of the accessory 2.

The disadvantage of the former method is that when connecting the connector bins having the same pin number, it is necessary to connect the vias 5 and the posts 3b one by one with the electric wires 6 as shown in FIG. 2, which clearly results in poor work efficiency.

The latter only uses the spring properties of the attachment tool 2 to hold down the post 3a, so it has poor vibration resistance, and only the corner parts that hold down the post 3a are in contact with the post.
If the contact area is small and the current carrying capacity is large, there is a problem in terms of reliability. Furthermore, it is expensive because it is gold plated to reduce contact resistance.

An object of the present invention is to provide a connection board that can easily connect pins of the same pin number when a plurality of printed wiring board connectors are adjacent to each other.

In the present invention, a large number of printed wiring board connectors are installed adjacently, and the number of connections between each printed wiring board is small, and the number of wires and soldering locations are reduced to connect pins of the same pin number of each connector. A special connection plate was invented in order to increase work efficiency by minimizing the number of connections.

An embodiment of the present invention will be described below with reference to FIGS. 3, 4, and 5.

As shown in FIG. 5, the printed wiring board 9 is attached to the connector 4 and electrically connected to each other. The connecting plates 10 are according to the present invention, and are each provided with semi-cylindrical extruded parts 11 (hereinafter referred to as extruded parts 11), into which the pins 5 of each connector 4 are inserted and attached by soldering. At this point, the pins 5 attached to the connectors 4 and the connection plate 10 are electrically connected, and the pins 5 of the same number -e of the adjacent connectors 4 are also connected at the same time. FIG. 3 is an enlarged view of the connecting plate 10 according to the invention. [Extrusion part] In order to smoothly insert the pin 5 attached to the connector 4, the extrusion dimensions are the same as the dimensions between the pins 5 of the connector 4, and the size of the extrusion part 11 is slightly larger to match the shape of the pin 5. It is manufactured.

FIG. 4 is an enlarged view of the extrusion part 11, and the connecting plate '10

is formed.

According to this embodiment, since the connecting plate IO and the extruded portion 11 are formed as one piece, it is possible to save material costs, shorten the work process, and reduce costs.

According to the present invention, it is possible to easily connect the pins of adjacent connectors by using a connecting board, which greatly reduces the number of wires and reduces the number of locations with solders, which significantly reduces work time. A significant shortening can be obtained.
