Creating Custom Knockout Holes in the Electronic Enclosures

There are ladies that are not ready to be called and perceived as a “girlie” girl. They have the tendency to exemplify the disgracing attitude of a drunk three legged bull making them not ready for sports. Boys can have the tendency to teach women about the rules, stats, and terminology of nearly every sport imaginable on the planet. Just by watching the episode of a sports commentary show – the commentators will discuss about the recent boxing match that just happened. The new terms that one can get are TKO (technical knock out.) It is easy to figure this out but it is not common to know the T in TKO. Because it is more common to hear KO in these scenarios.

So imagine if someone who are well versed in technology heard about the knockouts in enclosures. Obviously, it is not the same TKO or knock out in boxing however, the concept is quite similar when it comes to enclosures. A customer was looking for two different versions of a same case. The other versions should have one hole on the left while the other should have one on the right. In effort to be cost-efficient, the customer is looking for a way to produce one version in larger batches rather than just producing enclosures in two small batches. In order for them to do this, they should look for a way on how to only have one hole showing at a time.

To be able to do this, there is an option to make a machine knockout on the enclosure to make a thru-hole. The knockout should be essentially look like a round hole except that there are 2 small webs of plastic material that can hold the plastic slug in the hole. If the end users want to use the hole, they should simply break the webs of material to be able to remove the slug. This is what they call knocking out the material.

In other terms, companies can use machines that makes both holes as thru-holes and they can just simply cover the un-needed hole. There are enclosure manufacturing companies that does not carry products that cover or plug holes. There are different companies offering that type of products. Just by searching on Google, one can easily find a cover or plug holes for the enclosures.

How to Capture a PCB Using Two Screw Towers?

Just recently, I instantly decided to get rid of my unneeded furniture placed in the basement. It was already old, out of style and it so happens that my cats are living down in the basement. The furniture was completely covered in my cat’s fur because my two white cats loves to sit on the (then blue) white couch. Anyone who will see my furniture will tell me that it looks completely gross. And it is.

And because of presence of fleas, I decided to move the chairs by myself. I cannot wait for my boyfriend to arrive even if he is just 20 minutes away from my house. I almost got near the carpet but for once I decided to drag it upstairs. I just don’t have the energy to turn it to then haul it out open to the door.

When I carefully looked at the chair, I hefted the back of the chair onto the stair to make it leveled up to the front end whilst stepping up to the next level of the stairs. I said to myself, “one step at time.” I just patiently keeps on repeating this mantra as I slowly inch my way up to the stairs just balancing the two legs of the chair. When I finally got to the landing of the chair, I had to make the turn. I just hefted the back left leg of the chair onto the landing platform just in front of the right leg on the front end. While the chair is recently balanced like this on opposing legs, I just have to push it all the way to make a safe landing.

With this in mind, why should my impatience about furniture hauling matter? This is because without the ability to balance the chair on two opposing legs, I should have not succeeded. I recently got this idea from an enclosure making company that just launched their hand-held plastic enclosures. The unique enclosure design shows how it sandwiches a PCB between two screw towers.

There are customers who have asked how this works and they show a doubtful face that says “How does this keep the board from flexing?” The place of the board on the enclosure, then insert (and tighten) the screws into the screw holes on the enclosure. Which is now threaded unto the screw towers. This is primarily because the enclosure is so slim, that it leaves no room for the board to easily flex or twist like that inside the enclosure.

The screws can easily hold down the opposing corners of the PCB board. Thus making it just level and stable once the enclosure is successfully screwed together. This also allows the end user to use the space that surrounds the PCB without the need for the mounting attachments of bosses made in most sizes. However, because of the extra length of the KT-70, the mounting bosses are finally included for the additional stability.
