If it is divided according to the material, there should be more copper terminals. According to the style, there should be more plug-in terminals and spring-type terminals.
      Spring-type terminal blocks are new types of terminal blocks that utilize spring-loaded devices and have been widely used in the world's electrical and electronic engineering industries: lighting, elevator lift control, instrumentation, power, chemical and automotive power. The spring-type series terminal metal parts are all spring device design, and the plastic body is made of PA66 insulation material. The spring-loaded series of terminals are easy to operate, free to service and have a gas-tight contact system that is durable, reliable and cost-effective.
     The plug-in series terminal block PTB is made up of two parts plugged and unplugged, one part is pressed and then inserted into another part, which is soldered to the PCB board. This bottom mechanical principle, this anti-vibration design ensures long-term airtight connection and reliability of the finished product. The ears can be assembled at both ends of the socket. The mounting ears can largely protect the tabs and prevent the tabs from being placed in a poor position. At the same time, the socket design ensures that the socket can be correctly inserted into the maternal body. The socket can also have an assembly buckle and a locking buckle. The mounting buckles provide a more secure attachment to the PCB, and the locking tabs lock the parent and socket after installation. A variety of socket designs can be used with different mating methods, such as horizontal, vertical or tilted printed circuit boards, etc., depending on the customer's requirements. You can choose either a metric wire gauge or a standard wire gauge.
