Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a program switch device that includes contact portions that perform switch functions in the vertical and horizontal directions and connects and separates them using pins.

Conventionally, so-called DIP switches that have ultra-small DUAL-INLINERACKAGE array pins that have a switching function and are programmed have already been known as seesaw types, slide types, toggle types, etc., which are classified according to the switch operation part. It is widely used for programming the connection and disconnection of signal lines.

However, the above-mentioned DIP switch has a movable part such as a switch operation part, but is made to be extremely small, making it difficult to assemble and expensive.
There are drawbacks such as being limited to turning off the device and also requiring a locking mechanism.

In addition, like the above-mentioned DIP switch, a large number of pins are arranged and protruded from the insulator in two rows, and the pins facing each other are connected in advance with a short-circuit body, and when used, the short-circuit body is connected as appropriate. Disconnectable connectors are also known.

However, although the above-mentioned connector does not have the drawbacks described above, it has a fatal drawback in that once it is programmed for use by cutting off the short-circuiting member, it cannot be changed.

The present invention eliminates the above-mentioned drawbacks, has a normally closed type mechanism in addition to a normally open type mechanism, and uses insulated pins in addition to conductive pins to connect and disconnect circuits, making it easier to program. The present invention proposes a program switch device that is easy to set and change, has no moving parts like a DIP switch, has a simple and inexpensive mechanism, and provides stable contact resistance.

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

As shown in FIG. 1, this program switch device consists of a socket A, and a plurality of conductive pins B and insulating pins C, each of which is provided in plural numbers, although only one of each is shown.

Socket A has a plurality of contacts 1 arranged in two rows in front along the longitudinal direction (lateral direction) in a horizontally elongated housing a made of an insulating material.

The housing a is constructed by covering a base 2 with a cover 3.

These base 2 and cover 3 have recesses 2 and protrusions 3 provided on both sides of the base 2 and cover 3 that fit into each other.
As shown in FIG. 2, the groove 22 on the side of the recess 2 and the protrusion 32 on the side of the protrusion 3 are fitted into each other, and the cover 3 is attached to the base 2.
This prevents it from coming off carelessly.

Each contactor 1 has a parallel contact portion 1 □ for short-circuiting contactors 1 in two rows that are opposite to each other, that is, contacts in the vertical direction, and a contactor 1 in the same row.
The serial contact portions 1□ for short-circuiting adjacent ones, that is, the ones in the horizontal direction, are formed upright, and the connecting terminal portions 13 are bent downward and used as a base. 2 and protrudes outward.

The distance X between the connecting terminal portions 13 of the contactors 1 divided into two rows is, for example, 7.62 mm, and the distance between the connecting terminal portions 13 of the adjacent contactors 1 of the same row is 7.62 mm. 13 is, for example, 2.54 mm.

Of the contactors 1 divided into two rows, those located at mutually opposing positions have their parallel contact portions 1 □ facing each other at their intermediate positions, and the opposite parallel contact portions 1 There are two types of combinations: one set that is in contact with each other due to spring force, and the other set that is separated from each other and simply faces each other.

Therefore, it can be said that a set of contacts 1 whose parallel contact parts 1□ are in contact with each other forms a so-called normally closed circuit, and a set of contacts 1 whose parallel contact parts 1□ are in contact with each other constitutes a so-called normally open circuit. It can be said that it is composed of

Also, among adjacent contacts 1 in the same row, the serial contact portion 1□ has the same relationship as the parallel contact portion 1□ described above, and the serial contact portion 1
There are sets in which the angles are in contact with each other and sets in which they are far apart.

The cover 3 of the housing a has through holes 4 at respective locations corresponding to the parallel contact portions 1 facing each other as described above, and between the serial contact portions 1 □.
It is perforated.

The conductive pin B and the insulating pin C have exactly the same external shape and size, but are made of different materials; one is made of a conductive material while the other is made of an insulating material.

Therefore, the conductive pin B is inserted through the through hole 4 between the parallel contact parts 1
If you insert it between 2, the normally open circuit will be closed.

Further, the insulating pins C are connected to a pair of parallel contact portions 1. which are in contact with each other through the through holes 4. If it is forcibly inserted between the two or serial contact parts 12, the contact will be separated and the normally closed circuit will be opened.

Incidentally, a circuit for preventing backflow of current may be formed by incorporating a diode, a resistor, or other electromagnetic electronic component inside the conductive pin B in the above embodiment. In this way, the application of the electronic circuit can be improved. It can be made even wider.

Therefore, according to the present invention, for example, if the horizontal direction of the socket is made a normally open circuit and the vertical direction is made a normally closed circuit in advance, and the circuit is configured with conductive pins or insulated pins, the entire socket becomes a normally open circuit. The number of conductive pins used is significantly smaller than that of the conventional type, and the degree of contact failure caused by the conductive pins is reduced, improving reliability.

In this way, the circuit can be disconnected and connected by a simple operation of inserting and removing the insulating pin in addition to the conductive pin into the through hole, and the program can be easily set and changed.

In addition, the structure is simple and inexpensive, and stable contact resistance can be obtained.
