Description

DETAILED DESCRIPTION OF THE INVENTION The present invention connects a plurality of circuits by inserting a plurality of pin terminals into a conductive insertion portion provided on a printed circuit board and selectively making them conductive. This invention relates to a program connection device that can be disconnected.

Conventional connection devices of this type include the following.

(A) As is known from Japanese Utility Model Publication No. 52-1498y, a shorting contact incorporated in an insulating cliff body is soldered directly to a pin of a specified terminal board mounted on a printed circuit board or to a printed circuit board. (o) As is known from Japanese Utility Model Publication No. 51-22255, there are plugs that protrude paired pin terminals that are connected to each other in advance, and sockets that have pin terminal holders. The pin terminal of the plug is inserted into the pin terminal receiving part of the socket to short-circuit the pin terminal receiving part.

1. A so-called structure in which a large number of pins are arranged and protruded in two rows, and the opposing pins are connected in advance with a short-circuit body, and the short-circuit body is appropriately cut when used. The circuit is fixed.

However, each of the conventional connection devices has the following points.

That is, in the case of (A), it is necessary to prepare a variety of short-circuiting contacts with different connection directions, such as facing, left, right, and diagonal directions, and one pin cannot be connected overlappingly.

Also, similar to [〇〇's one], in addition to having to prepare various plugs, it is not possible to connect multiple pin terminals. Furthermore, since Shiichi's method uses a short circuit by cutting it, it cannot be changed once it has been programmed.

Therefore, the present invention does not have the above-mentioned drawbacks, that is, the connection/disconnection of multiple circuits can be programmed in a semi-fixed manner, making it very easy to program, and the program can be changed very easily by inserting and removing pin terminals. Furthermore, we have proposed a program connection device that allows for duplicate connections.

The invention will now be described in detail with reference to the illustrated embodiments.

In FIG. 1, A is a printed circuit board according to the present invention, B is a temporary dustproof bar that can be placed over the printed circuit board A, and C is a socket into which the printed circuit board A is inserted.

In the printed circuit board A, a conductive material 2 is printed on the surface of an insulating substrate 1, through holes arranged in two rows are bored on the conductive material 2, and a sleeve 3 manufactured by Dendenmura is installed as a shield. .

As shown in detail in FIG. 2, the sleeve 3 has flanges 3a and 3b at both upper and lower ends of a cylindrical shape, and the sleeve 3 has flanges 3a and 3b that penetrate through the insulating substrate 1.
a and 3b face the outside of the upper and lower surfaces of the insulating substrate 1. A large number of pin terminals 4 made of conductive material are removably inserted into the sleeve 3.

As shown in detail in FIG. 3, the pin terminal 4 has an almost round bar shape as a whole, but it has an enlarged part 4a that is crushed and swelled laterally in the middle of the upper part, and the upper end is also shaped like a round bar. The pin terminal 4 is crushed to form a flat knob 4b, and by pinching the knob 4b and inserting the enlarged part 4a into the sleeve 3, the tip 4c penetrates the top and bottom of the printed circuit board 1, and the enlarged part 4a is inserted into the sleeve 3. The portion 4c is adapted to lie closely adjacent to the sleeve 3. The socket C has pin terminal through-holes 6 arranged in two rows in the insulating shell 5, and female pins 7 corresponding to the pin terminal through-holes 6 arranged in rows inside the insulating lotus body 5. Become.

Incidentally, grooves 5a and la are formed in the insulating shell 5 and the insulating substrate 1 to align them with each other.

The dustproof cover B is box-shaped with an opening on the bottom, made of transparent insulating material, and has numbers on the top surface that match the sleeves 3 so that the sleeves 3 can be identified from the outside when covered with the printed circuit board A. It is displayed.

In the present invention having the above configuration, in order to program the circuit connection/disconnection using the printed circuit board A,
The printed circuit board A is remounted on the upper surface of the socket C with the grooves la and 5a aligned, and the pin terminal 4 is selectively inserted into the sleeve 3 and the tip end 4a of the pin terminal 4 is inserted into the terminal through hole 6.

In this way, the enlarged portion 4a of the pin terminal 4 comes into contact with the inner surface of the sleeve 3, and the tip end 4c comes into contact with the female pin 7, so that electrical conduction is established between the conductive material 2 and the female pin 7. Therefore, according to the present invention, in order to change the program after inserting the pin terminal into the sleeve, it is only necessary to insert or pull out the pin terminal into another sleeve as appropriate, and programming can be done with a simple operation. Can be done.

Furthermore, even if the sleeves are once connected to each other by a conductive substance, the connection can be broken by cutting the conductive substance.

Furthermore, circuit elements such as semiconductor elements, resistors, and capacitors can be printed or mounted on the insulating substrate.

Therefore, according to the present invention, the connection/disconnection of multiple circuits can be easily programmed in a semi-fixed manner, and the program can also be changed by a simple operation of inserting and removing pin terminals, which has the effect of allowing redundant connections. .
