What Components Do Automotive Connectors Have?
Typically, contact pins, insulating housings, shells, and accessories make up automotive connectors. The contact pin is the essential component of the connector that makes up the electrical connection function. In general, the terms “connector contact” and “female connector contact” refer to the male and female connectors, through whose secure connection the signal transmission is completed. Insulators, also referred to as base or mounting plates, are used to position and space pins as desired, as well as to guarantee insulation between pins and between pins and shells.
Basic specifications for insulating materials include good insulation resistance, voltage resistance, and machinability. The housing is the connector’s outer casing. It protects the pins and built-in insulating mounting plate from mechanical damage and ensures that the plug and socket inserts are properly aligned to keep the connector attached to the object.
It is anticipated that the market for automotive connectors will continue to expand due to the global ratio of new energy vehicles and the continued uptake of automotive intelligence. However, when using automotive connectors, pins frequently need to be taken out for inspection or replacement. We therefore need to understand how to remove pins from connectors.
How Do I De-pin From The Connector Using A Specialized Tool?
Numerous automakers have introduced their own new energy vehicle products, such as hybrid and pure electric vehicles, in response to the new energy vehicle industry’s rapid development. A crucial component of the vehicle’s power transmission system is the wire harness, and the connector serves as the wire harness’s crucial connecting element. The locking structures on the pins of strong electric connectors are locked by opening the locking plate. They cannot be pushed out in the direction of insertion when they are locked.
Because of this, disassembly or repair without specialized tools is extremely time-consuming and difficult, or it can only result in the destruction of the plug pins. Please don’t be concerned; we have specialized disassembly tools. We can easily remove the connector’s pins thanks to this unique disassembly tool. The special tools on the right side of the handle are fixed with an internal empty sleeve, which is inserted into the connector socket head and set on the outside of the pin, forward extrusion lock until the lock pieces together, the pin into the sleeve inside whole again, and finally drive the pin back together, releasing the fixed clamping groove of the pin to achieve the goal of de-pin from the connector.
It is significant to note that it is challenging to fully insert the pin into the deep position of the sleeve and insert the sleeve into the retaining clamp groove of the connector socket at the same time. The sleeve cannot be inserted into the fixed clamping groove at all when the outer diameter of the pin is close to the inner diameter of the fixed clamping groove of the connector socket. It cannot be quickly and conveniently pushed out of the pin even if it can be inserted because pulling it out in the opposite direction is more challenging. When in the assembled state, the front end of the auto connector unlocking sleeve protrudes from the front end of the thimble. To unlock, the connector’s locking sheet can be compressed back to the contraction position.
After completing the disassembly of the pin under pressure spring of rebound, the thimble can promote launch socket connector pins and recover the pin; the entire launch process using a single action is very accurately rapid, efficient, convenient, saves time and effort, and the pin is in good condition to be used again. According to various connector pin types, you can alter the unlock sleeve’s size.
De-pin And Re-pin Technique
Step 1: Find The Right Tools
Ensure that you have the appropriate tools for the repair. Having the appropriate connector repair tools is essential whether you decide to solder and shrinkwrap your repair or use the depin/repin technique. The majority of the ones you require are already here. These connector and wire repair tools will work just as well for a much lower cost than the well-known brands while maintaining the high quality you expect.
Step 2: Take Off The Front Cap.
The green covering is referred to as the front cap (see red arrow).
Using a depin tool, carefully pull out and pull off the front cap to expose the “catches”
Step 3: Release The “catch”
The “catches” are the tiny plastic components that firmly secure the terminals/pins (observe the blue circles).
Either a connector depin tool or a small screwdriver can be used to gently lift up the catch.
Step 4: Release And Pull
With your other hand, carefully pull the wire that goes with the terminal you are releasing as you release the catch by gently lifting it up or away from the terminal.
*important note: pulling the wire and lifting up the catch has to be done at the same time so you do not risk damaging the pigtail by pulling with too much force.
Step 5: Insert The Terminal/pin Back Into The Pigtail (rear Side)
If you want the terminal to fit neatly into the back of the pigtail, make sure you line it up properly. Once it is properly inserted into the slot, you will hear a slight “click.”
Step 6: Check The “catches”
Verify that each catch is snugly fastened next to the terminal and sits flush next to it.
Step 7: Insert Green Cap Back On And Inspect
Check to make sure all seals and the green cap are in place.
In the world of new energy vehicles, the automotive wiring harness connector is a crucial component that directly affects the capacity of signal and power transmission. The development of the new energy automotive industry in recent years has had a significant impact on the gradual advancement of the automotive parts industry, which in turn has had an impact on the development of automobile connectors for reliability and refinement. A crucial component of signal transmission, the automotive connector pin’s dependability is crucial, and strict control is required. Summarizing the issues with connector pin usage, we discovered that the pin is susceptible to damage during assembly or disassembly, so it’s important to know how to remove the pin from the connector properly.
