DC JACK

●認識DC JACK:                  

首先我們要來認識一下消費性產品上面是用了什麼規格的插座(Jack),以及它們正確的名稱(以常見者為例)。                

1.2.1mm  DC Jack (DC插座):請看雅安科技的目錄,注意看照片,插座裡面有一根針,2.1mm就是那根針的直徑。

2.  2.5mm  DC Jack :與上面的是同一種類的插座,只是裡面的針直徑較大,為2.5mm。

3.3.5mm  Mono Phone  Jack (耳機插座):請看雅安科技目錄,這東西本來是插耳機的,但是國外一些廠商像是MXR或EH就拿來當直流電源插座。而效果器的輸入輸出用的是6.3mm的 Phonejack3.5mm 是指插座的孔徑。 Mono 是單聲道的意思。

●認識插座極性:

  各位應該有個概念,就是供電的時候, 電源插座的正極要接電路的正極,電源的負極要接電路的負極,這樣電路才可以工作。而且正電負電不可以直接搭在一起,這樣電源會發生短路,電源電路沒有加保護措施的話會燒掉。接著我們來看一個東西....

左邊這個圖大家一定常常在一些電器的機殼上面看過。我覺得一個負責任的廠商應該做這樣的標示(使用直流的場合)。這個圖代表的意思就是電源插座的極性為外正內負。所謂外就是DC插頭的外面那圈,內就是給插座那根針插進去的部分。大家如果買到2.1mm的 DC  Plug 可以拿起來把孔朝著自己,就會看到類似該圖的樣子了。

  而 3.5mm  mono phone jack 慣用的插座極性,剛好與慣用的相反。Why???很簡單,因為這種phone  jack的外圈通常是金屬的,而且與金屬機殼相通。通常信號 Input/Output 的 6.3mm 耳機插座的外圈( Sleeve )是用為參考電壓的連接(接地,與電源的負極相通)。綜上所述,我們可以說使用 3.5mm  mono Phone Jack 的插座極性絕大部分是外負內正

●圓線與並排線的差別:

 電源插座並排線是由兩條電線並排而成,一條為黑色,一條為黑白色。這種線比較容易做剪斷互接的處理,上熱縮套比較方便。圓線則是比較美觀,但是剪斷互接不好操作。

●直頭與L頭的差別:

直頭比較佔用空間,L頭比較不佔用空間。電源棒的  輸出端可以選用直頭。

Left unchecked, diabetes cause long-term body impairment, generating in some cases through heart problems, cva or cerebrocascular accident, prospect decrease, kidney breakdown, ankle amputation and / or departure, research projects demonstrate to.
Anyone with the help of diabetes should certainly discuss with some dietitian towards make meals package personalised at their specified preferences, analysts assert. And yet you can find total recommendations.
Carbohydrate-rich foodstuffs, of which fail to carbs and glucose in prevent, are actually from important challenge in any diabetic's food plan. Men and women who usage nourishment insulin injection therapy — frequently Design 1 diabetes sufferers many Design step 2 diabetes sufferers — routinely have towards count up typically the h from carb supply many partake of by every different dining event to enable them to make theirselves the precise insulin measure.
But sugars commonly are not typically the opposition and / or truly the only consideration.
" Whatever is so important virtually all might be the quantity of families partake of, " believed trained diabetes mentor Marion Franz, some Minneapolis-based eating habits not to mention healthiness adviser. Should families slim down 100 % day to day excess calories, in spite of the food stuff foundation, ordinarily his or her's blood sugar grades drop, many families reduce weight, of which even assists you to tremendously, Franz believed. Taking things excessively, perhaps even sensible food, are generally risky, this lady believed.
It's ordinarily highly recommended for everyone to take as few as step 2, 000 excess calories day to day, despite the fact who ıs determined by overall body capacity not to mention standard of muscle stimulation, Franz believed.
Diabetics can't take away sugars altogether, despite the fact jointly limitation these products not to mention decide upon nutritionally unique sugars (veggies, totally grains) finished drained products (sugars, revamped grains), believed Amy Campbell, broker of this surgical coaching systems by Joslin Diabetes Cardiovascular, a study provider attributed with Harvard Medical related Higher education.
Typically diabetes sufferers should certainly make an attempt to partake of 20 towards 55 h from carb supply in every dining event, not to mention 15 towards 20 h in every snack food, in order to get spread around his or her's carbo in your diet in the daytime, this lady believed. In some cases individuals not to mention enthusiastic exercisers are designed for further.
Counting sugars are generally problematic, which means Campbell indicates using the Western Diabetes Association's sheet tactic for creating meals: Enter into about half a sheet with the help of nonstarchy veg (carrots, broccoli, spinach), 25 percent with the help of good required protein amounts (fish, chicken) and then a one with the help of high-fiber starches (brown hemp, quinoa, beans). Insert a totally plant (not juice, of which isn't actually for the reason that sealing not to mention in some cases possesses further sugar) not to mention a particular 8-ounce decanter or glass from nonfat and / or low-fat get. Foodstuffs prefer mozzarella cheese are generally used through a small amount.
Avoiding bad fats, along the lines of melted foodstuffs not to mention high-fat food, is really as fundamental for the reason that reviewing sugars, for the reason that those who diabetes are certainly more as opposed to more than once certainly going to be affected heart problems as opposed to families free of, Campbell believed.
Diabetics are able to partake of sugars now and again — need not reject one self some portion from torte within your special — on condition that many trade through a second carbo not to mention continue being according to his or her's 100 % carbo plan, believed Catherine Browning, resident diabetes coaching administrator from the Or even from Md Cardiovascular for the purpose of Diabetes not to mention Endocrinology. Which means, nix typically the hemp in meals any time you intend to partake of quiche for the purpose of piece of food.
