Description

[0001]
[Technical field to which the invention belongs]
In the present invention, for example, when a plurality of manifold valves for driving an actuator by pneumatic pressure are connected in parallel, the relay line is used to relay a bus line for transmitting a control signal to each valve at the position of each valve. The present invention relates to a relay connector in which a connector is attached to each valve and adjacent ones are connected to relay a control signal.
[0002]
[Prior art]
Conventionally, as the above-described relay connector, as shown in FIG. 6, a male socket 2 and a female socket 3 each having an L-type connection terminal are mounted on a substrate 1, and connection wiring between these sockets 2 and 3 is provided. The printed wiring is formed on the substrate 1.
[0003]
Since the socket contacts of the male socket 2 and the female socket 3 described above are formed in two upper and lower stages as the number of signal lines increases, the L-type connection terminals 2a, 2b, 3a, 3b are arranged in two rows in the front and rear. Therefore, these contact terminals are connected on the substrate 1.
[0004]
FIG. 7 shows the wiring state of the L-type connection terminals 2a, 2b, 3a, 3b on the substrate 1, and these connection terminals 2a, 2b, 3a, 3b are soldered on the substrate 1, and further on the substrate 1 The outer connection terminals 2b and 3b facing each other are connected by a straight line 4a, and the inner connection lines 2a and 3a are connected to each other in order to avoid the outer connection terminals 2b and 3b. Connection is made by a bent wiring 4b passing between 3b.
[0005]
In such a connection state, since each connection terminal 2a, 2b, 3a, 3b is soldered, a soldering space for soldering is required around the hole into which the terminal is inserted. Further, since the connection between the inner connection terminals 2a and 3a is routed between the outer connection terminals 2b..., 3b.
[0006]
Therefore, ignoring these soldering space and wiring space, the pitch of each connection terminal 2a ... 2b ... 3a ... 3b ... cannot be reduced, in other words, the male socket 2 and the female socket There is a problem in that the width of the relay connector cannot be reduced in size by reducing the pitch of the connection contacts of the socket 3.
[0007]
Further, on the above-described substrate 1, the back surfaces of the male socket 2 and the female socket 3 are opposed to each other, and the four connection terminals 2a, 2b, 3b, 3a are arranged in a straight line between them. Since the soldering space and the wiring space cannot be neglected, in other words, the thickness direction of the relay connector (opposite direction of the male socket 2 and the female socket 3) cannot be formed small. Has a problem.
[0008]
[Problems to be solved by the invention]
In the present invention, the pitch interval of the connection contacts can be reduced as much as possible to reduce the interval in the pitch direction, that is, the width, and the width in the thickness direction where the male socket 2 and the female socket 3 are opposed to each other. An object of the present invention is to provide a relay connector that is small and compact and can be easily changed and assembled in signal wiring.
[0009]
[Means for Solving the Problems]
This invention is a relay connector with a board and a female contact member and the housing, the other end to the substrate, with the male contact portion is printed formed on one end edge side than the one end edge side edge to said connecting portion for connecting with a female contact member connects the male to contact portion electrically printed form, the female contact member, the substrate is connected to the connection portion of the substrate connection a Department, the female contact portion Ru extending outwardly of the other end edge side of the substrate are formed integrally with, the housing, the substrate of the female contact member and the connecting portion of the substrate holds the substrate and the female contact member in a state where the connecting portion is connected, have a opening in one side and the other side corresponding to the one edge side and the other end edge side of the substrate, one of said housing with the opening of the side the male contact portion is exposed, one Side connection fitting portion is formed, together with the opening of the other side of the housing to expose said female contact portion, the one side connection fitting portion capable other side connection fitting of the relay connector isomorphous A fitting portion is formed, and the one-side connection fitting portion and the other-side connection fitting portion are fitted, whereby the male contact portion and the female contact portion of the same-shaped relay connector are It is configured to be electrically connectable.
