Abstract

A device having anti-demolition functions includes a housing and an electronic apparatus. The housing includes a first cover and a second cover. The first cover has a first connection part disposed thereon. The electronic apparatus is disposed in the housing and is fixed on the second cover. The electronic apparatus includes a first block, a second block and a join part. The second block has a second connection part disposed thereon, wherein second connection part fastens first connection part when first cover is engaged with second cover. The join part connects first block and second block, and has at least one circuit wire passing there through, wherein when the first cover and the second cover are separated from each other, the join part is separated from at least one of the first block and the second block, such that the at least one circuit wire forms an open circuited status.

Claims

1. A device having anti-demolition functions, comprising:

a housing, comprising a first cover and a second cover, wherein the first cover comprises a first connection part disposed thereon, wherein the first connection part is fixed on the first cover; and

an electronic apparatus, disposed in the housing and fixed on the second cover, the electronic apparatus comprising;

a first block;

a second block, comprising a second connection part disposed thereon, wherein the second connection part fastens the first connection part when the first cover is engaged with the second cover, wherein the first block and the second block are printed circuit boards (PCB); and

a join part, for connecting the first block and the second block and having at least one circuit wire passing through, wherein when the first cover and the second cover are separated from each other, the join part is separated from at least one of the first block and the second block, such that the at least one circuit wire are broken into more than one pieces.

2. The device of claim 1, wherein the first connection part is an anti-dismantle fastener and the second connection part is a hole;

and when the first cover is engaged with the second cover, the anti-dismantle fastener is inserted into the hole in order to fasten each other.

3. The device of claim 2, wherein an axis of the anti-dismantle fastener comprises a pillar, and a top of the pillar comprises at least one blocking part disposed outwardly and a gap disposed inwardly;

and when the anti-dismantle fastener is inserted into the hole, the blocking part penetrates the hole and fastens the hole.

4. The device of claim 1, wherein the second connection part is an anti-dismantle fastener and the first connection part is a hole;

and when the first cover is engaged with the second cover, the anti-dismantle fastener is inserted into the hole in order to fasten each other.

5. The device of claim 4, wherein an axis of the anti-dismantle fastener comprises a pillar, and a top of the pillar comprises at least one blocking part disposed outwardly and a gap disposed inwardly;

and when the anti-dismantle fastener is inserted into the hole, the blocking part penetrates the hole and fastens the hole.

6. The device of claim 1, wherein there is a U-type groove existed between the first block and the second block.

7. The device of claim 1, wherein the second cover further comprises at least one supporting stilt for supporting the second block.

8. The device of claim 1, wherein when the first cover and the second cover are separated from each other, the first connection part still fastens the second connection part, thereby the join part is separated from at least one of the first block and the second block.
