Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a connector device, and particularly to a connector device for distributing the same signal to a plurality of devices or circuits.

BACKGROUND OF THE INVENTION In systems that include multiple circuits or devices with similar functionality, the same signal may be distributed to each of the devices. For example, a color video projector uses three cathode ray tubes (R, G, B), each of which receives the same horizontal and vertical deflection signals. Conventionally, such signal distribution has been achieved by using a plurality of connectors 2,
3 and 4, which takes up space. Although only three connectors are shown in the diagram, in reality, a total of 12 connectors are arranged in parallel to accommodate two supply lines for each horizontal and vertical deflection signal for each deflection yoke, which takes up a considerable amount of space. . Since connectors for sending common signals to other cathode ray tube power supply circuits, electron tube heater circuits, etc. are similarly arranged in parallel, this space problem cannot be ignored.

DISCLOSURE OF THE INVENTION The present invention was created in view of the above-mentioned problems, and provides a connector device that requires less space, is easy to handle, and has high safety for supplying the same signal to multiple devices or circuits. The purpose is to provide.

To achieve this objective, the connector device of the present invention includes a conductive unit body formed into a substantially cylindrical shape to be fitted into a common terminal post;
A conductor piece is integrally formed on one side of the unit body so as to be coupled to the conductor portion of the two lead wires, and a conductive protrusion is integrally formed on the inner surface of the unit body so as to press into contact with the common terminal post. A plurality of connector units arranged so as to surround a common terminal post and each connected to a plurality of lead wires are accommodated in a stacked state in the axial direction of the common terminal post. The structure includes an insulating casing that is formed into a cylindrical shape and has an opening on the side surface for passing each lead wire.

In the present invention, signal transmission between the common terminal post and each lead wire is performed via a connector unit coupled to the lead wire. That is, the signal from the common terminal post passes through the protrusion of each connector unit, the unit body, and the conductor piece to reach the conductor portion of the lead wire.

In the present invention, since a plurality of connector units are stacked in the axial direction of the common terminal post, the overall required space remains constant and small regardless of the number of lead wires. Furthermore, since no special mounting hardware or screws are required, it is easy to attach and detach the lead wires. Further, since the connector unit forming the contact portion between the common terminal post and each lead wire is housed in an insulating casing, it is safely electrically isolated and protected from the outside.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to FIGS. 2 to 6.

FIG. 2 shows the appearance of a connector device according to an embodiment of the present invention. Three supply lines or lead wires 12, 13, 14 are connected in a vertical line to a connector device 11 mounted on a printed circuit board 10. The other terminals of these leads 12, 13, 14 are respectively connected to similar functional circuits or devices, such as three cathode ray tubes R, G, B (not shown) of a color video projector. These connector devices 11 and lead wires 12,1
3 and 14 provide one transmission conductive means for one common signal, for example a horizontal deflection signal, and in fact are similar connector devices 11' and leads 12', 13 which provide the other transmission conduction means. ′、
14' (not shown) is also attached.

Components of the connector device 11 are shown in FIG.
Three connector units 16, 17, 1 are connected to one common terminal post 15 installed upright on the printed circuit board 10.
8 are stacked and fitted in a vertical line in the axial direction of the terminal post. The terminal post 15 is made of brass, for example, and is connected to a signal source (not shown) via printed wiring on the back side of the board. terminal post 15
The height of the connector unit is selected depending on the total height of the plurality of (three in this embodiment) connector units arranged there. The connector units 16, 17, 18 are
For example, the unit body is made of brass or phosphor bronze and has a substantially cylindrical hollow rectangular parallelepiped body with an open bottom and top (only the bottom of the top unit 16), and a corresponding lead wire in the lateral direction. 12,1
3 and 14, respectively, mechanically and electrically. In this embodiment, this connection is made by conductor pieces 16a, 17a, 18a integrally formed on one side of the unit body of the connector units 16, 17, 18.
Conductor portions 12a, 1 of lead wires 12, 13, 14
Although this is done by wrapping 3a and 14a and crimping them together, other suitable means, such as soldering, may be used. connector unit 16,
The casing 20 housing 17 and 18 together is
A cylindrical body made of a suitable insulating material, with an opening 20e on one side for passing lead wires connected to each unit.
and is arranged so as to surround the common terminal post 15. As shown in FIG. 4, inner protrusions 16b and 17 are provided on both sides of the unit body of each connector unit 16, 17, and 18 adjacent to the lead connection surface.
b, 18b are provided, and when the unit is inserted into the common terminal post 15, the inner projections 16
b, 17b, and 18b come into pressure contact with the terminal post 15, thereby forming an electrical connection. Also, on the side facing the lead connection surface, an outward lance 16 is provided.
c, 17c, 18c are formed, and these step portions 20a, 20 formed on the corresponding wall surfaces of the casing 20
b, 20c to prevent detachment from the casing 20. However, if the connector unit is to be removably housed in the casing 20, the lances can be retracted inward so that they do not engage with the step.

As described above, in this embodiment, three connector units are arranged in a vertical line on one common terminal post, and the required space is approximately 1/3 of that of the conventional individual parallel arrangement type. It has been reduced to

FIG. 5 shows an example in which two connector devices as shown in FIG. 1 are integrally connected. Such a continuous connector structure is convenient in practice since pairs of connector devices are typically attached as a set, as described above. It should be noted that a larger number (for example four) of consecutive structures is of course also possible.

FIG. 6 shows an example of a structure in which openings are provided on three sides of the casing 20' so that the directions of the lead wires are different, which is convenient when the directions in which external devices are arranged are greatly different.

Effects of the invention As described above, according to the invention, the conductor portion of each lead wire is connected to a conductive connector unit that can be fitted into a common terminal post, and each connector unit is connected to the common terminal post. They are housed in an insulating casing while stacked in the axial direction, and the electrical connection between each lead wire and the common terminal post is made by the conductor piece of the connector unit,
It is obtained through the unit body and the inner protrusion.

As a result, the space required for the entire device is constant and small regardless of the number of lead wires, the lead wires can be easily attached and detached because no special mounting brackets or screws are used, and the common terminal post and each lead Since the contact portion (connector unit) between the wires is housed in an insulating casing, remarkable effects such as safe electrical isolation and protection from the outside can be obtained.
