Description

Electronic component, ceramic antenna and electronic device using the same

technical field

The invention relates to an electronic component, a ceramic antenna and an electronic device using the same, in particular to an electronic component with elastic parts, a ceramic antenna and an electronic device using the same.

Background technique

With the development of science and technology, the application of various electronic components is becoming more and more common in daily life. Generally speaking, in order to integrate the application of various electronic components, the electronic components are further used by being electrically connected to a circuit board. Therefore, the way of assembling the electronic component and the circuit board often affects the electrical connection relationship between the two and the cost and time of assembling.

Take a ceramic antenna assembled on a circuit board as an example. Please refer to FIG. 1 , which shows a schematic diagram of a traditional ceramic antenna assembled on a circuit board. The ceramic antenna 10 is assembled on the circuit board 30 through an iron frame 20 and a clamping member 40 . The iron frame 20 and the clamping member 40 are generally fixed on the circuit board 30 by Surface Mount Technology (SMT). The iron frame 20 has a hole 21 , so that the two curved surfaces 41 of the clip 40 are exposed through the hole 21 . When the ceramic antenna 10 is to be assembled on the circuit board 30, the ceramic antenna 10 is adhered to the iron frame 20 by double-sided adhesive (not shown), so that the signal transmission port 11 of the ceramic antenna 10 is clamped through the hole 21 The two curved surfaces 41 of the holder 40 are clamped. In this way, the ceramic antenna 10 can not only be fixed on the circuit board 30 , but also can be electrically connected to the circuit board 30 through the clamping part 40 and the iron frame 20 .

However, the manner in which the ceramic antenna 10 is assembled on the circuit board 30 as shown in FIG. 1 often requires complicated steps. In addition, the signal transmission port 11 clamped by the two curved surfaces 41 is often prone to poor contact. The signal transmission port 11 is generally cylindrical, that is, a cylinder with a curved surface. Therefore, when the two curved surfaces 41 sandwich the signal transmission port 11 which also has a curved surface, the contact mode is point contact. When the ceramic antenna 10 is bumped, the contact between the signal transmission port 11 and the two curved surfaces 41 is likely to be slightly displaced, resulting in poor signal transmission. Furthermore, since the traditional ceramic antenna 10 must be assembled on the circuit board 30 through the iron frame 20 and the clamping member 40 respectively, it is difficult to greatly reduce the production cost.

Therefore, how to make the ceramic antenna or the electronic components to be assembled on the circuit board electrically connected to the circuit board under the premise of meeting the consideration of time and material cost is one of the subjects that the related industry strives for.
