Do you know that the electrical connector is divided into several parts? Electrical connector In order to meet the SMT process requirements, the terminal pad products are strictly required flatness and coplanarity, usually the industry standard coplanar 0.10max, otherwise it will lead to poor use of PCB welding products.

1.Rubber body

The structure is spaced from the plastic pallet fence, holding a small pitch and providing a holding force after the terminal assembly arrangement. According to the requirements of the product, the plastic body has sufficient strength and toughness, as well as before and SMT welding can not be warped. The following describes the specific design of the plastic body and the choice of materials.

2.the terminal FPC terminal / FFC connection contact member to achieve the use of narrow film material to select the conductivity and good mechanical strength of the phosphor bronze connector high density arrangement and more stable contact performance, FPC / FFC connector terminal contact The way.

Typically, the design of the terminal structure will be two ways, one is the flat material under the stamping end, the other is stamping after forming the terminal bending. Since the narrow gauge pitch terminal type needs to have sufficient flexibility and a relatively complex shape, it is difficult to control the size and accuracy of the difficulties caused by stamping and punching. Thus, the female terminal is usually used to form the pattern.

Because of the FPC / FFC connector application, which is characterized by a straight FFC / FFC compatible plug, the terminals are classified as female terminals. It is also often used to cut patterns.

3. latch

When the FPC / FFC is inserted, the FPC / FFC is locked with a spring lock to maintain a certain contact force. It needs a rigid part is not good enough, usually PPS raw material.

Step 1: Pull out the connector latch

Step 2: Insert the FPC / FFC

Step 3: Self-locking connector lock Small distance, multi-wall structure FPC / FFC connector Shaping mechanism

Used to enhance the aerosol plugs are firmly connected to the PCB, and can avoid the terminal, because the stress is too large terminals and PCB welding damage. After that, the requirements for assembling the welding plate are the same as those of the terminal. In the pin less electrical connector, the solder is not a mandatory part.
