Abstract

PURPOSE:To ensure electric connection cutting to/from a plurality of circuit units or peripheral equipment in a small mounting space by mounting and demounting an integrated group of connectors whose one side connectors have a function of coupling with other side connectors. CONSTITUTION:In the case of inserting a connector 2 and a connector 3 into a connector 1, the hook 22 of the connector 2 and the hook 33 of the connector 3 are coupled with the bar 11 of the connector 1. This process may prevent the connector 2 and the connector 3 from coming off the connector 1, and ensure the connection between a control circuit within a printed board (a) connected to the connector 1 and a plurality of circuit units, connected to the connector 2 and the connector 3, or peripheral equipment. In the case that a connector coupling plate 333 is removed in the condition that the connector 1 and the connector 2 and also the connector 3 are in their connected situation if the hook 33 is removed from the bar 11, the connector 3 can be mounted and demounted independently.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION Conventionally, control of a plurality of circuit units and peripheral devices added to an apparatus has been performed by electrically connecting them to one or a plurality of printed boards having the control circuit. In recent years, with the improvement in the degree of integration of logic circuits, it has become possible to electrically connect one smaller printed board having the control circuit to a plurality of circuit units and peripheral devices for control. Accordingly, it is required that a smaller printed board having the control circuit can be electrically connected to a plurality of circuit units and peripheral devices. However, when a conventional connector for one-to-one electrical connection is used, the connector mounting area in the printed board for electrically connecting to a plurality of circuit units and peripheral devices becomes large, and the control inside the printed board is increased. The circuit mounting area is limited.
Therefore, it is difficult to realize the miniaturization of the device by high-density mounting.

The present invention is particularly applicable to a limited connector mounting area in a printed circuit board by connecting connectors from a plurality of circuit units and peripheral devices to enable attachment / detachment with a connector mounted on the printed circuit board. The present invention relates to a connector that enables connection with a plurality of circuit units and peripheral devices and realizes downsizing of a device by high-density mounting.

2. Description of the Related Art FIG. 4 shows a block diagram of a prior art (Japanese Patent Laid-Open No. 63-43278).

The connector 5 is mounted on the printed board 4, and the terminals of the connector 5 are connected to signal lines in the printed board for electrical connection between a plurality of circuit units or peripheral devices and the control circuit of the printed board. ing. The relay connector 8 is
It is interposed between the connector 5 and the connector 6 and the connector 7, and is electrically connected to relay signals of both.

By connecting / disconnecting the relay connector 8 and the connector 5 with the connectors 6 and 7 inserted, it is possible to collectively electrically connect or disconnect a plurality of circuit units or peripheral devices. Further, by individually attaching or detaching the connector 6 or the connector 7 with the relay connector 8 inserted in the connector 5, it is possible to electrically connect or disconnect the required circuit unit or peripheral equipment.

[0006]

In recent years, as the degree of integration of logic circuits has improved, a plurality of circuit units or peripheral devices and a smaller printed circuit board having a control circuit therefor are electrically connected to each other to form an apparatus. Miniaturization is required.

In the prior art, a plurality of circuit units, peripheral devices, and a printed circuit board are provided by interposing a relay connector 8 between one connector 5 and the other connector 6 and connector 7, which correspond to each other. Connects and disconnects with the internal control circuit at once.

However, the following matters have not been taken into consideration.

(1) Since the relay connector 8 is interposed between the one connector 5 on the one hand and the plurality of connectors 6 and the connector 7 on the other hand, there is a space for accommodating the relay connector 8 in the connector attaching / detaching part. It is necessary and the device cannot be downsized. Further, when the relay connector 8 of the connector attaching / detaching part is housed in the printed board, it is necessary to secure an area for housing the relay connector 8 in the printed board, and the mounting area of the control circuit in the printed board is limited. receive.

(2) Since there is no disconnection prevention mechanism between one connector 5 on one side and a plurality of connectors 6 and connectors 7 on the other side and the relay connector 8, a reliable electrical connection cannot be guaranteed. As a result, it cannot be applied to important parts that require reliability that affect the operation of the system.

(3) When the relay connector 8 and the plurality of connectors 6 and 7 are attached and detached, the connector 6 and the connector 7 may be inserted into the relay connector 8 in reverse.
As a result, a problem may occur in electrical connection between the plurality of circuit units or peripheral devices and the control circuit in the printed board, and the circuit units, peripheral devices, or the control circuit in the printed board may be destroyed.

An object of the present invention is to enable electrical connection or disconnection by collectively attaching and detaching one connector on one side and a plurality of connector groups on the other side without using a relay connector, and prevent disconnection. By providing a mechanism and an erroneous insertion prevention mechanism, it is possible to obtain high reliability and realize miniaturization of the device by high-density mounting.

[0013]

SUMMARY OF THE INVENTION According to the present invention, one is for integrating one connector and the other is for collectively attaching and detaching a plurality of connector groups, and the other is for integrating a plurality of connector groups with each other. Provide a combining function. Further, after the connector group is inserted into one connector into the other connector group and the other connector group is inserted into the connector group, a disconnection prevention function is provided to prevent the connector from being disconnected unless it is manually removed. In addition, when one connector is inserted into one connector and a plurality of connector groups is inserted into the other connector, an erroneous insertion prevention function is provided to prevent insertion into positions other than mutually defined positions.

[0014]

According to the present invention, in one connector and the other in a plurality of connector groups, one is integrated with one connector by a coupling function, and the other is a relay connector in which a plurality of connector groups are attached and detached. It becomes possible without any, and electrical connection or disconnection can be performed collectively.

Further, the disconnection preventing function enables an electrically reliable connection between one connector on the one hand and a plurality of connector groups on the other hand. Here, if one connector is inserted into one connector and the other is inserted into multiple connector groups, the other connector connector can be attached / detached by releasing the connection function and disconnection prevention function of an arbitrary connector of multiple connector groups. Therefore, electrical connection or disconnection with a plurality of circuit units or peripheral devices can be performed individually. Further, by prohibiting insertion of one connector on one side and a plurality of connector groups on the other side at positions other than the determined positions, erroneous insertion is prevented and electrical connection or disconnection with a plurality of circuit units or peripheral devices is prevented. Can be carried out without error, and destruction of a plurality of circuit units, peripheral devices and their control circuits can be avoided.
