How to ensure the various retention forces in the production of pin and row mother

Ensure the state (position) of the contact terminal (conductor) during the manufacturing or use of the pin and the female processing, and avoid external forces (such as pulling when the wire is welded during the manufacturing process; The thermal deformation force of the SMT process.

The force during plugging and unplugging, the force generated by impact or vibration during use, etc.) cause the contact terminal (conductor) to deviate from the working position, resulting in loss of connection function.

Test Method: EIA-364-29

Test points:

Test the image for the entire connector.

The test action point is the direction in which the connector is normally used (the reverse direction of terminal assembly).

Unless otherwise specified, the speed is 25.4mm/minute.

for destructive testing.

Specification requirements: generally set the minimum value (5.0N Min.).

The terminal retention force is defined to ensure that the terminal (conductor) is fixed in the plastic. The terminal assembled in the plastic is in the manufacturing process (such as welding/pulling during product handling/SMT process) and in the use process (such as male and female insertion process).

The pin row mother processing is subject to vibration and impact) will receive external force, so the holding force of the terminal and plastic must be sufficient to not cause the terminal to withdraw PIN after receiving unexpected force, resulting in connection interruption and connection function failure.

Role:

What is the role of the row pin in the electronics industry?

Widely used in computer motherboards, video phones, automotive electronics, rail transit, display screens, power meters, electronic toys, medical equipment and optoelectronic products and many other fields.

In the current industry, almost every electronic consumer product has a standard interface and a corresponding card point interface connector. A problem that cannot be ignored with the use of such an interface in a car.

Because the specifications required by different products are not the same, there are also many types and specifications of pin headers. According to the standard classification of pin headers in the electronic industry, they can be roughly divided into 0.8mm,1.27mm,2.0mm,2.2mm,2.5mm,2.54mm,3.96mm and 5.06mm types. According to the number of rows, there are single-row needles, double-row needles, three-row needles, etc.

According to the packaging rules, there are SMT (horizontal/vertical), plug-in DIP (straight/bent), etc.

The purpose of the connector

Improve the production process The electrical connector simplifies the installation process of electronic products. It also simplifies the mass production process. Easy to repair. If an electronic component fails, it can quickly replace the failed component when a connector is installed. It is convenient for promotion to follow the progress of skills. When connectors are installed, they can update the components and replace the old ones with new and more perfect components. The flexibility of progressive design enables engineers to design and integrate new products and use components to form systems, there is more flexibility. Because the structure of the connector is increasingly diversified, new structures and application areas continue to appear, trying to use a fixed form to deal with classification and naming problems, it has become difficult to get used. Nevertheless, some fundamental classifications are still useful.

Take you to know the connector

Connector, namely CONNECTOR. Domestic also known as connectors, plugs and sockets. Generally refers to the connector. That is, a device that connects two active devices and transmits current or signals. It is widely used in aviation, aerospace, defense and other military systems. The connector is a component that our electronic engineering technicians often touch. The SIM card connector is a common smaller connector, which is used in electronic products such as mobile phones and computers. Its effect is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to complete the function of the reservation. Connectors are components that cannot be missing in electronic equipment. If you investigate the path of current flow, you will always find one or more connectors. Connector mode and structure is ever-changing, with the use of different targets, frequency, power, the use of the environment, there are a variety of different ways of connectors. For example, the connector used to light the lights on the court is very different from the connector of the hard drive, and the connector used to light the rocket. However, no matter what kind of connector, it is necessary to ensure that the current flows smoothly and reliably. In general, the connector is not limited to the current. Today, with the rapid development of optoelectronic skills, in the optical fiber system, the carrier of the signal is light. Glass and plastic replace the wires in the general circuit. However, connectors are also used in the optical signal path, and their effect is the same as that of the circuit connector.
