Description

[Detailed Description of the Invention] So-called DIP switches are already known in which ultra-small DUAL-IN-LINE array pins with switching functions such as follower, seesaw type, slide type, and toggle type are provided in a printed circuit board. .

Such DIP switches are widely used in computers, automatic control, vending, etc. because they can be easily switched when programming to disconnect or connect signal lines.

Also, connect a large number of pins to the above DIP switch in the same way.
Conventionally, there have been connectors in which connectors are arranged in rows, and those facing each other are connected in advance with a short-circuit body, and the short-circuit body is appropriately cut off when used. However, the above-mentioned IP switch is difficult to assemble and is expensive because the switch mechanism is made ultra-small.

(o) Circuit switching is limited to turning on and off opposing pins or adjacent pins; turning on and off diagonally is not possible, and if you try to do it forcibly, you will sacrifice vertical and horizontal pins. It has to be sexual. However, the current capacity is inevitably small due to the mechanism, and the operating temperature range is narrow. 9 Lock machine side may be required.

{Village) There are drawbacks such as the need to operate a switch for each circuit when changing the program. Also, although the above connector does not have the drawbacks mentioned above,
On the other hand, since the short-circuit body is cut and used, there is a fatal drawback that once the program is programmed, it cannot be changed.

The present invention does not have the above-mentioned drawbacks; in other words, it is possible to connect multiple circuits at the same time with a single operation of attaching a connector to a socket, and it is also possible to switch diagonally. Since it has no moving parts, the paulownia mechanism is simple and inexpensive, and stable contact resistance can be obtained, and it is also possible to switch between small currents, and Dm type I
We have proposed a completely new programming device that can be equipped with C and of course allows easy program changes.

In the following, the invention will be described in detail with reference to illustrated embodiments.

As shown in FIG. 1, this programming device consists of a socket A, which is its main body, and several conductive connectors B, which can be detachably connected to the socket A.

The socket A has a horizontally elongated recess 1 formed on the upper surface of its housing a made of an insulating material, and a plurality of grooves 2, 22 (grooves 22, 22) at regular intervals along both sides of the recess 1. In Figure 1, 7 pieces each) are arranged in a row.

The grooves 2, 22 on both sides of the recess 1 face each other in a one-to-one relationship. As shown in FIGS. 2 and 3, each groove 2,
, 22 is equipped with a contact 3 having a support portion 3', and an output terminal portion 3'' of the contact 3 penetrates through the housing a and projects outward from the lower surface of the housing a.Connection. The child B is removable from the recess 1, and seven identical pieces are shown in FIG. 1, each having the groove 2 on both sides.
, , 22 each have one protrusion 0 and Q that can be retracted freely. Therefore, by arranging all seven of these in the recess 1, the respective protrusions q and b2 will be seated in the opposing grooves 2, 22, and the clamping portion 3' of the contact 3 therein will The contacts 3 on both sides of the recess 1 are connected to each other in pairs as shown in FIG. 5. After loosening the connector B into the recess 1 in this way, in order to prevent the connector B from coming off and to position it, a plate-shaped inner cover 4 is ironed onto the housing a from above, and the upper side is then covered with a casing. It is covered with a transparent dustproof cover 5 screwed onto A.

The inner lid 4 has a closure 6 and grooves 2, which correspond to the recess 1.
22 are formed with corresponding grooves 7, 72 in a one-to-one relationship, and are numbered in the vicinity of the grooves 7, 72. In addition, a plurality of connectors B placed in the recess 1 are -
To enable simultaneous extraction, an extraction bar 8 is provided as shown in FIGS. 3 and 4.

This extraction bar 8 is slidably fitted into a long groove 1' formed on the bottom surface of the recess 1, and is attached to the oblique protrusions 8, 82 on both the left and right sides.
By sliding it along the inclined recesses 1, 12 of Saicho 1', it floats and lifts the connector B. The connector B shown in FIG. 1 has one protrusion b, , etc. so that the contacts 3 on both sides of the recess 1 can be connected in pairs to each other. , 6th
~ As shown in Figure 18, for one connector B, the number of protrusions 0 and b2 on both sides is increased to a plurality, or those protrusions q and Q
Various types of circuit connections can be made by preparing various connectors B, such as having different numbers of connectors B, using only one side, or providing protrusions b or b2 at intervals.

In addition, in the above example, the connectors 3 can be short-circuited by making the connector B itself conductive and ironing it. It may also be equipped with a fuse to prevent overcurrent, and it may also be made of insulating material, which normally keeps the circuit open and prevents malfunctions. It may be possible to prevent this.

Therefore, according to the present invention, multiple circuits can be connected at the same time by a single operation of placing a contact on a socket, and diagonal switching is possible, so programming can be simplified.

In addition, since there are no moving parts and the circuit is semi-fixed, experimentation is simplified and stable contact resistance can be obtained at low cost. Furthermore, it has many effects such as being able to turn off all circuits at the same time using the extractor bar.
