Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a connecting device for connecting input/output signals to a circuit unit such as a printed circuit board included in a measuring instrument, a communication device, or the like.

In general, measuring instruments, communication devices, and the like are required to be smaller and lighter in order to make the devices more economical and easier to transport, install, and the like.

Conventionally, in the above-mentioned electronic device, the connection configuration of input/output signals to the circuit unit is, for example, the first
As shown in the figure, a connector mounting panel 4 is provided in a subrack 2 disposed in a device housing 1, and a plurality of signal processing printed circuit boards 3 on which transistors, integrated circuits, etc. are mounted are provided on the front surface of the subrack 2. The input/output wiring for these printed circuit boards 3 is connected, for example, by connecting external equipment to the small multi-connector 5 into which the printed circuit board 3 is inserted. Because it is not possible to directly connect thick input/output cables from
The small multi-connector 5 for the printed circuit board and the large multi-connector 7 provided on the relay connector collection panel 6 are connected by a relay wire bundle 8, and further connected to external equipment via the large multi-connector 7. I was trying to make a physical connection.

However, in the above-mentioned input/output signal connection configuration, as shown in the figure, there is a small multi-connector 5 for printed circuit board and a large multi-connector 7 for relay.
The relay wire bundle 8 that connects the cables between the terminals and the terminals becomes complicated as the wires extend outside the housing, and a large multi-connector for relaying is required. Therefore, it has been difficult to miniaturize these devices.

Therefore, the present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to improve input/output between a signal processing circuit unit disposed within a device housing, for example, a printed circuit board and external equipment. Connections do not require wire bundles or relay connector collection panels, etc.
A compact and extremely rational circuit unit connection device that integrates a printed circuit board connection connector and an external connection connector into the same molded structure with a reduced connection volume, thereby making it possible to downsize electronic equipment. is to provide.

In order to achieve the above object, the circuit unit connecting device of the present invention includes a frame-shaped main body having a guide groove on one side surface for allowing a circuit unit having a connecting connector at one end to be inserted from the entire surface. A unit connection connector for connection to the connector of the circuit unit is provided at the rear end of the main body, and an external connection connector for external connection is provided on the entire surface of the main body. An electrical connection means is provided on the side opposite to the unit insertion side so that the signal line from the unit connection connector and the signal line from the external connection connector can be connected from the outside. It is something.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a circuit unit connecting device according to the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a perspective view showing the structure of an embodiment of the circuit unit connecting device of the present invention, in which 21 is a frame-shaped main body made of an insulating material such as polycarbonate;
On the front side thereof, an insertion guide groove 23 is provided so that a plug connector, for example, a circuit unit having a small multi-connector 31 for printed circuit boards at one end, that is, a printed circuit board 30 can be inserted, and the rear end of the guide groove 23 A jack connector 24 is disposed in such a way that a small multi-connector (plug connector) 31 for a printed circuit board provided on the printed circuit board 30 can be inserted and connected thereto. Further, as shown in the figure, a large multi-connector 25 for external connection is provided near the front end of the guide groove 23, and a frame-shaped body is provided between the jack connector 24 and the large multi-connector 25 for external connection. Electrical connections are made within 21 by buried conductors (not shown). However, an electrical connection means is provided between the jack connector 24 and the large multi-connector 25 for external connection, that is, as shown in FIG. A recessed electrical connection portion 26 is provided with a plurality of conductor terminals 27a, 27b, . . . , and a plurality of conductor terminals 28a, 28b, .

Therefore, if the circuit unit connecting device having the above-mentioned structure is arranged in a sub-rack or the like installed in the housing of an electronic equipment device, the circuit unit, for example, a printed circuit board having a small multi-connector 31 for printed circuit boards at one end, can be installed. 30 is inserted along the guide groove 23 provided in the frame-shaped main body 21, and inserted into the jack connector 24 provided at the rear end of the guide groove 23.
The input/output signals are connected to the inserted printed circuit board 30 through the guide groove 21 of the frame-shaped main body 21.
It is only necessary to connect a thick input/output cable from an external device directly to the large multi-connector 25 for external connection provided near the front end of the There is no need to use large relay multi-connectors, wire bundles, etc. for connection. In addition, each connection terminal of the jack connector 24 into which a circuit unit such as a printed circuit board 30 is inserted can be easily connected to each connection terminal of the large multi-connector 25 for external connection in the recessed electrical connection portion 26. It can be replaced.

As is clear from the above description, the circuit unit connecting device of the present invention has a circuit unit jack connector, an external connection connector, and an electrical connection part integrated into a frame-like body. If used in an electronic device or the like, the wiring structure within the device can be simplified and the device can be easily miniaturized. In addition, the electrical connections between each connection terminal of the inserted circuit unit and each connection terminal of the external connection connector can be easily changed to any connection within this device, making it extremely easy to use. It has excellent effects.
