Problems solved by technology

When the mold is opened, the position where the side key is ejected from the two-shot mold cannot be set on the appearance surface. Generally, a protruding surface is formed at the connection between the key body and the support body to be supported by the ejector mechanism, which is easy to cause ejection. The side key is damaged when the mechanism is ejected, making it difficult to demould the side key, reducing the molding yield of the side key, and even damaging the double-material injection molding mold in severe cases

Abstract

The invention discloses a side key, which is used for an electronic device of a printed circuit board with a shell or arranged inside a shell. The side key comprises a support and a key body which are molded by double-material injection. The support is connected with the shell of the electronic device, a contact used for triggering the printed circuit board of the electronic device is formed on the support, and the contact and the support are respectively formed on two opposite sides of the support. A groove used for the ejection of the side key during double material injection molding is formed on the surface of the side key, which is connected with the support. The groove enables the molded side key to be ejected out of an injection mold conveniently, thereby improving molding yield, avoiding the damage to the mold if that the side key is kept in the injection mold, and prolonging the service life of the mold. The invention also provides an electronic device applying the side key.

Description

technical field [0001] The invention relates to a side key and an electronic device using the side key, in particular to a side key using double injection molding and an electronic device using the side key. Background technique [0002] Electronic devices such as mobile phones, digital cameras, MP3 and MP4 are usually equipped with side buttons, and users can realize a specific function by operating the side buttons, such as taking pictures, adjusting volume, playing music, etc., thereby enhancing the convenience of use. [0003] Existing side keys generally include a support body and a key body combined with the support body. The supporting body is arranged on the side of the printed circuit board of the electronic device, and the side of the supporting body facing the printed circuit board is formed with outwardly protruding contacts. By pressing the key body of the side key, the operator triggers the contact on the support body to trigger the side key switch arranged on...
