Ⅰ  Terminal Connector

1）Female Terminal

2）Female Connectors/Receptacle/Socket

3）Male Terminal/pin/tab

4）Male Connector/plug

Ⅱ  Lock part

1）ISL(Independent secondary lock).It is used for locking and fixing the terminals, which is the independent component out of the connector housing.【Picture A】

ISL of Molex643191219

2）TPA(Terminal position assurance). TPA is also the component which place the terminals in its right position,but it is different from the ISL,TPA is a part of the connector.【Picture A】

3）PLR(Primary lock reinforce). PLR‘s function is almost similar as TPA.【Picture B】

4）Latch. It is the lock structure between two mating connectors. In general, we call it primary lock of connector.

5）CPA(Connector position assurance). Just like TPA, CPA assure the two connectors connect and fix in the right position. CPA is as the secondary lock for connectors precisely.But CPA is not necessary to be applied in all environments. Usually Latch is adequate to assure the connect well, but if the vibration is frequent, we suggest to use CPA for doubling guarantee

6）Lever/Lever lock. This component is often found on some big connector, like the “big” CPA, but it works much better than the former.

Ⅲ Seal

1）Mat Seal. Play a role of waterproof protection in the connector housing.

2）Ring Seal. It is seated between female and male connector for waterproof protection

3）Wire Seal. Crimped with wire in the end of terminals for waterproof protection

4）Plug. Insert it in the unoccupied hole of connector for waterproof protection.

Ⅳ  Polarization Options

We also call it Coding. It is aFool-proofing design, and different polarization has different color.

Connector Base Structure

1) The bridge structure protect the connector latch.

2) The guide avoid the tilt when the connectors are connecting

3) All the angles have the big diameter and chamfer

4) The polarization structure assure the correct match between connector and connector and device,

5) Good Ergonomic structure is in favor of connector moving.

6) Good auditory and vision feedback

7) Fix the blank positon to assure the terminal is on the same plane.
