Description

  The present invention relates to a connector, and more particularly to a connector having a thinning effect.

  The connector is mainly used to connect two different devices, and is one of the indispensable parts especially for electronic products. As electronic products become lighter and thinner, connectors have evolved following changes in the times.

  The metal terminal of the conventional connector is assembled to the insulation body using a pin (PIN) insertion method. Mainly, a wide contact is provided on the metal terminal, and it interferes with the insulation body with the contact, and the metal terminal is effectively fixed to the insulation body.

  However, since this means fixes the metal terminal inside the insulating main body, it is necessary to secure a large space, increasing the volume of the entire connector, and it is impossible to realize a lightweight and thin electronic product.

  Therefore, connectors for fixing metal terminals using an injection molding method have been introduced into the market. This type of connector is mainly assembled to an insulating body after fixing different rows of metal terminals by an injection molding method.
