Hello, I'm Josh Bloom.
2
Welcome back to the RSP Supply Education Series.
3
In today's video, we're going to be talking about different types of terminal block connection types.
4
More specifically, we're going to be focusing on the Phoenix Contact Clip Line Terminal Blocks.
5
So today, we're going to talk about the five different connection types that Phoenix Contact offers with their terminal blocks.
6
The first type of connection is the screw type connection terminal block.
7
That is shown right here.
8
This is the most common type of connection that you'll find with terminal blocks.
9
It's been in the industry for a very long time.
10
You simply use a precision screwdriver to make the connection with a stripped wire.
11
Let me demonstrate how you make the connection.
12
You insert the wire into the terminal port and simply tighten your screw until your wire has been properly torqued.
13
The next type of terminal block connection we're going to talk about is the spring cage connection, which are located right here.
14
The benefits of using the spring cage connection are going to be, it's a much quicker way to terminate and disconnect wires.
15
They're very safe and sturdy and secure, much like the screw type connection.
16
Let me demonstrate how to make the connection.
17
We first take a wire and strip that back about one half inch.
18
We are going to need to use a precision screwdriver, which we will insert into the spring cage.
19
And then we can simply insert our wire, make sure that's fully seated, and then remove our precision screwdriver.
20
We now have a very secure, safe, tight connection.
21
The next type of terminal block connection we want to talk about today is referred to as PIT or push -in terminal.
22
The benefit of using this type of terminal block connection is a tool -free connection.
23
This allows operators to easily remove and reinsert wires without the need for any type of tool.
24
For the wire that's used on a PIT or push -in terminal connection, we need to make sure that we're using a ferrule.
25
The ferrule allows for the connection to work properly and seat properly.
26
We simply take the wire with the ferrule connected, we insert it into the push -in terminal, make sure it is seated fully,
27
and there we have a fully seated, safe, secure connection.
28
To remove this connection, we simply take a precision screwdriver, push down on the spring, which allows us to remove the wire very simply.
29
The next type of terminal block connection we want to talk about today is referred to as Fast Connect.
30
The benefit of using this type of terminal block connection is
31
it allows the operator to terminate the wire without the need for stripping the insulation.
32
This is also a gas -sealed connection, which helps us prevent the wire from becoming corroded or degraded in any way.
33
Let me demonstrate how we make this connection.
34
Simply take a wire that has not been stripped of its insulation, insert it into the proper terminal, make sure the wire is fully seated.
35
Take a precision screwdriver, insert it into the slot, pry that terminal back to the center of the terminal block.
36
What this does is it allows the terminal block to displace the insulation to make proper contact with the wire.
37
Once we've done this, we have a very secure, safe connection that required no tools.
38
The last type of terminal block connection we want to talk about today is referred to is a barrier terminal block.
39
The benefit of being able to use a barrier terminal block is it allows us to use a ring
40
or spade terminal at the end of our wire.
41
This type of terminal block is commonly used in the rail and transportation industries or where vibration might become a common problem.
42
Let me demonstrate how we make this type of connection.
43
We first want to make sure that our wire has either a spade or ring terminal properly crimped and connected.
44
Then we are going to insert the ring terminal over the bolts on the barrier terminal block.
45
We're going to push the lever down on the top of the terminal block until it is fully seated.
46
Then we're going to take a common flathead screwdriver and secure the nut over the bolt.
47
At this point we have a secure connection that will resist loosening due to vibration we might encounter.
48

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
