Ejector headers are usually made of head shaped plastic and square needles similar to animal cattle. The difference of the ejector connector is that the simple ejector has more clips on both sides. According to the requirements, the external dimensions of the ejector connector commonly include 1.27 spacing, 2.0 spacing and 2.54 spacing; According to the different spacing, the diameter of the square row of needles used will be changed accordingly. The contact surface between the bottom and PCB board can be designed as SMT patch type or DIP direct insertion 180 degrees. Function: After the ejector is welded on the PCB, connect the IDC flat cable of the corresponding specification, and then form the circuit connection mode required by the designer with other circuits, usually used to transmit control signals and weak currents.

The ejector connector is one of the connector categories. It is called the ejector connector because its shape is similar to the ejector. The ejector connector is a very simple internal wiring device. This article mainly introduces the usage of the ejector connector for the connector manufacturers.

How to use the ejector connector:

When using the ejector connector, it is usually necessary to pay attention to the insertion direction, perpendicular to the insertion direction and inclination.

1. Insertion direction:

When the connector is fully inserted to U=14.2, the specified contact resistance shall be guaranteed.

2. Perpendicular to the insertion direction:

If the printed board or fixed board mounted connector is floating mounted, the design of free and fixed board mounted connectors shall give an adjustable displacement of at least 1mm.

3. Inclination:

The design of free and fixed board mounted connectors allows inclination error, with longitudinal axis of ± 4 ° and transverse axis of ± 4 °.

4. Type C, R and M shall be preferred, and their overall dimensions and installation methods shall comply with relevant provisions of IEC60603-2. PCB punching drawing shall refer to relevant drawings in connector parameter library.

5. On the mounting surface of the European connector's reference frame fixed plate connector, the line passing through the center of the mounting hole is used as the reference line, and the nominal center near the mounting hole of No. 32 contact is used as the reference point.

6. For RF mixed type ejector connector, the frequency range, impedance characteristics, VSWR and insertion loss of RF terminals should meet certain requirements, and the impedance must match with the connector.

7. If there are EMC requirements, the connector must meet EMC requirements.

8. Connector termination forms include crimping, PCB welding and other forms, which can be selected according to actual needs.
