Description

[Detailed Description of the Invention] (1) Field of the Invention The present invention relates to a mechanism for preventing erroneous insertion when an electronic circuit package is inserted into an electronic circuit package shelf, and in particular, a means for visually preventing this erroneous insertion is provided. 4L of prevention of incorrect insertion of Kameko enclosure package using visible method! Regarding Sakaki.

(2) Conventional technology and assembly point As shown in FIG. Display label 2l or electronic enclosure package product name display label 2
When inserting the electronic circuit package 1 into the electronic circuit package shelf 2, the electronic circuit package 1
A maintenance person can refer to the above electronic circuit package product name display 11 and these column number display labels 21 or electronic circuit package product name display labels 22 and check whether they match or not. This prevents the package l from being erroneously inserted into a position other than the crease contact position or the horizontal row on the electronic circuit package shelf 2.

However, such a conventional electronic circuit package insertion prevention mechanism prevents incorrect insertion of the electronic circuit package due to the He-Man error caused by mistaking each display label.
The drawback was that there was no way to prevent it.

(3) Object of the Invention The object of the present invention is to provide a mechanism for preventing erroneous insertion of an electronic circuit package, which improves the above-mentioned conventional drawbacks.

(4) Discrepancies of the Invention The electronic circuit baggage insertion prevention mechanism of the present invention, when an electronic circuit package is inserted into the electronic circuit package shelf, detects one of the insertion positions t (column) using a visual display means of the lamp number. By displaying the information, it is possible to prevent incorrect insertion of the electronic circuit package.

(5) Embodiments of the Invention FIG. 2 is a circuit diagram of a mechanism for preventing insertion of an electronic circuit package according to the present invention, and FIG. 3 is a structural diagram of a mechanism for preventing incorrect insertion of an electronic circuit package according to the present invention. The electronic circuit package misinsertion prevention mechanism shown in these figures includes contact lands 10a\rn on the upper and lower parts of the electronic circuit package 10,
The preliminary insertion position mark 10b is made smoothly and with a common mask pattern, and the light emitting diode IOC mounted on the electronic circuit bank 710 and the contact land 10JI on the top and part 1 of the electronic circuit package 10 are connected. , jumper ll1li to correspond to the nma electronic circuit package.
15, and a pair of vibrating lands 10m on the upper and lower parts of the electronic circuit package 1o are regarded as one woodcutter, and the n4m type wire pattern is determined.

Next, set the contact springs 20a at positions corresponding to the contact lands lO& on the upper and lower parts of the electronic circuit package 10 described above in the image of the upper and lower grooves of the electronic circuit package shelf 20. Alternatively, in the case of electronic circuit packages and IWJ, it is possible to assume a set pattern of the ridge contact springs 2°a in n different positions.

This nma set pattern is for electronic circuit package 20
and electronic circuit package shelf 30 with 35 screws, power supply (+5V) 30m and ground (E) 30m.
b to the upper and lower contact springs 20a of the electronic circuit package shelf 20.

In such a configuration, when inserting the electronic circuit package IO into the electronic circuit package shelf 20, first insert the electronic circuit package 10 into the preliminary insertion position, that is, the preliminary insertion position marks on the upper and lower parts of the front side of the electronic circuit package 10. 10b and electronic circuit package shelf 2
If the light-emitting tie IOC mounted on the electronic circuit package 10 ignites at this time, the electronic circuit package 10 will be placed in the correct position k (column). Since it shows that it has been inserted, insert the electronic path package 10 to the depth of the hole. What if the electronic circuit package 10? If the light emitting diode IOC mounted on the column does not light up, it means that the electronic circuit package 10 is not inserted in the correct position (column). Reinsertion of package 10 is performed in the same manner.

(6) As described in detail, the present invention prevents errors and errors that conventional electronic circuit package insertion prevention and sliding doors had no means to prevent. , the insertion position (column) of the electronic circuit package for one insertion of the 61 child circuit package.
Visually displaying the positive side of the problem has the effect of preventing it.
