Description

Technical Field [0001] The present invention relates to a connector and a mobile terminal including the connector,

The present invention relates to a connector and a mobile terminal including the same.

A terminal can be divided into a mobile terminal (mobile / portable terminal) and a stationary terminal according to whether the terminal can be moved. The mobile terminal can be divided into a handheld terminal and a vehicle mounted terminal according to whether the user can directly carry the mobile terminal.

The functions of mobile terminals are diversified. For example, there are data and voice communication, photographing and video shooting through a camera, voice recording, music file playback through a speaker system, and outputting an image or video on a display unit. Some terminals are equipped with an electronic game play function or a multimedia player function. In particular, modern mobile terminals can receive multicast signals that provide visual content such as broadcast and video or television programs.

Such a terminal has various functions, for example, in the form of a multimedia device having multiple functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game and broadcasting, etc. .

In order to support and enhance the functionality of such terminals, it may be considered to improve the structural and / or software parts of the terminal.

Inside the terminal, a circuit board on which various electronic components for performing functions of the terminal are mounted is provided. The circuit board is provided with a plurality of electronic elements and connection terminals to be electrically connected to an external configuration.

1 is a cross-sectional view showing a circuit board inside a mobile terminal according to the related art.

Referring to FIG. 1, on a substrate 2 according to the prior art, there is provided a connection terminal 4 to be electrically connected to an external configuration. The connection terminal 4 has a contact portion 5 at least partially protruded to be in contact with the external terminal 7. Accordingly, the contact portion 5 and the external terminal 7 are in contact with each other, so that the substrate portion 2 and the external structure can be electrically connected.

According to the substrate portion 2 having the above-described structure, since the connection terminal 4 forms a protruding region for contacting the external terminal 7, the contact portion 5 is formed on the body of the cooperator There is a high possibility that deformation occurs due to the engagement. Since the contact portion 5 is made of a metal material that is easily deformed, deformation occurs even with a small external force.

The deformation of the contact portion 5 eventually causes a terminal-to-terminal contact failure, so that the specific function of the product may not be performed or the operation of the terminal may not be performed.

Particularly, in consideration of the miniaturization of the terminal and the increase in the density of the electronic parts mounted on the board portion 2, the durability of the contact portion 5 must be ensured for stable connection between the board portion 2 and other components.

The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a mobile terminal having a connector which can be stably connected to other electronic parts.

According to an aspect of the present invention, there is provided a connector for electrically connecting a plurality of elements or electronic components to a substrate on which a plurality of elements or electronic components are mounted, A central portion having a contact portion in contact with the terminal; And a plurality of branch portions radially branched from the outer peripheral surface of the central portion, wherein the branch portion is banded downward from an outer peripheral surface of the central portion, and an end portion is coupled onto the substrate portion.

The connector and the mobile terminal including the same according to the present invention have the following effects.

First, there is an advantage that a connector for electrical connection with other electronic components is formed through a central portion and a plurality of branch portions branched from the central portion, thereby stably fixing the connector on the substrate portion.

Second, since the surface of the central portion having the contact portion is rounded, there is an advantage that the connector can be prevented from being deformed by an external force.

That is, in the metal plate having a plurality of extending portions extending from the center to the outside, an external force is applied to the end portions of the branched portions 1020 branched from the center, and the bent portions are bent downward, Can be formed.

FIG. 9 is a cross-sectional view illustrating a substrate unit inside a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 9, one or more connectors 1011 are provided on one surface of the substrate portion 181 to be electrically connected to other electronic components, as described above.

At this time, the other electronic part is provided with a contact terminal 2000 to be electrically connected to the substrate part 181. The contact terminal 2000 electrically connects the other electronic part to the substrate part 181 through physical contact with the connector 1011.

Accordingly, the central portion 1011, which is a protruding region, is disposed at the uppermost end of the connector 1000, so that the contact portion 2000 can be easily contacted. Also, in the assembling process of coupling the other electronic component and the substrate portion 181, since the rounded contact portion 1011 is brought into contact with only the contact terminal 2000, the connector 1000 is prevented from being deformed And the assembly process can be simplified.

FIG. 10 is a perspective view showing a modified example of the connector according to the present invention, and FIG. 11 is a cross-sectional view illustrating a process of assembling the connector according to a modified example.

In this modification, there is a difference in the number of the connectors 1000 and the branch portions 1020 described above. That is, the branch portion 1020 may be provided in a relatively smaller number than the connector 1000 described above.

That is, the number of the branched portions 1020 may be variously changed in consideration of the type of the electronic component to be coupled, the manufacturing cost, the size of the substrate portion, and the distance between the electronic component and the substrate portion.

For example, the number of branch portions 1020 can be increased for stable support in connectors that are combined with relatively heavy and bulky electronic components. In addition, when it is desired to reduce manufacturing cost by combining with relatively light electronic components, the number of branch portions 1020 may be reduced.
