Hereinafter, the connection terminal 10 and the circuit board module according to the embodiments of the present invention will be described in detail with reference to FIGS. 1 to 6. FIG. 1 is a perspective view of a connection terminal 10 according to an embodiment of the present invention, Fig. 2 is a front view of the connection terminal 10 of Fig. 1 mounted on the PCB 1, Fig. 3 Is a front view of the state in which the connection terminal 10 of Fig. 2 is pressed. 4 is a perspective view of a connection terminal 10 according to another embodiment of the present invention.

Referring to the drawings, a circuit board module according to an embodiment of the present invention may include a PCB 1 and a connection terminal 10 for connecting an antenna (not shown) built in the body of the mobile communication device. And the circuit board module can be used in various devices including mobile communication devices. Here, the object to which the connection terminal 10 according to the present embodiments is connected may include various components of the mobile communication device as well as the PCB 1 and the built-in antenna.

Although the following description of the 'upper' and the " lower " standards follows the directions shown in the drawings, the PCB 1 will be described, but the present invention is not limited thereto. Or the order, and the like are not limited.

The connection terminal 10 is mounted on the PCB 1 with the base portion 15 as a lower portion and the upper contact portion 11 is electrically connected to the mobile communication device. Further, the base portion 15 and the contact portions 11 are formed parallel to each other. Specifically, the connection terminal 10 includes a base portion 15, a contact portion 11, a bending portion 13, and a guide portion 17, and is formed as a single body.

The connection terminal 10 may be made of a conductive material and a metal material so as to electrically connect the PCB 1 and the mobile communication device. For example, the connection terminal 10 may be formed of gold (Au) or nickel (Ni). Alternatively, the connection terminal 10 is entirely made of nickel (Ni), and may optionally include a gold (Au) material. However, the present invention is not limited thereto, and the material of the connection terminal 10 may be variously changed if the material is conductive and has a predetermined elasticity.

The connection terminal 10 may be formed as a single body formed by cutting one plate or strip member and / or bending a plurality of times. That is, the base portion 15, the contact portion 11, and the bending portion 13 are formed as one body. Here, the connection terminal 10 may be formed of one plate member having the same thickness, or may be partly deformed in thickness.

The base portion 15 is a support portion of the connection terminal 10 and is formed flat to be mounted on the PCB 1. [ In addition, the connection terminal 10 is formed in a closed curve shape, and both ends can form the base portion 15. That is, the base portion 15 may be formed with the cut-out portion 16 so that the both end portions are spaced apart from each other by a predetermined distance. When the cutout 16 is moved when a force greater than a predetermined magnitude is applied to the connection terminal 10 by cutting the base 15 and forming the cutout 16 at a predetermined distance, It is possible to prevent the connection terminal 10 from being excessively deformed.

The contact portion 11 is formed parallel to the base portion 15 and is formed so as to be in contact with the mobile communication device. For example, the base portion 15 and the contact portion 11 are formed of a plate material having a size corresponding to each other, and are formed into a band or a rectangular shape with a predetermined length.

4, the contact portion 11 is formed to be in contact with the mobile communication device. The contact portion 11 includes a plurality of dimple portions (not shown) protruding at a predetermined height from the contact portion 11 12 may be formed. The dimple portion 12 is formed of a protrusion of a curved surface such as a hemispherical or dome-like shape so as to be in point contact with the mobile communication device on the contact portion 11 surface. Further, by forming the dimple portion 12, reliability of contact with the mobile communication device can be improved.

The bending portion 13 is formed by bending a plurality of times between the base portion 15 and the contact portion 11. [ The bending portion 13 is integrally formed with the base portion 15 and the contact portion 11, and is bent at least once. As shown in the drawing, the bending portion 13 is bent many times and bent at a plurality of bending points 131, 132 and 133 in the shape of 'w', and the base portion 15 and the contact portions 11 At both ends thereof. Further, the bending portion 13 is formed to be bent between the base portion 15 and the contact portion 11. As shown in FIG. 3, when the connection terminal 10 is pressed, the plurality of bending points 131, 132, and 133 are brought close to each other, so that the contact portion 11 is lowered and the height of the connection terminal 10 is lowered.

5 and 6, the bending portion 13 may be formed so as to connect one end of the base portion 15 to the other end of the contact portion. 5 and 6 will be described later.

According to these embodiments, by forming the bending portion 13, the connection terminal 10 can have elasticity of a predetermined size or more, and plastic deformation can be prevented from occurring. The shape of the bending portion 13 allows the connection terminal 10 to be connected to the built-in mobile communication device with a predetermined elasticity.

The width of the bending portion 13 may be equal to or thinner than the width of the base portion 15 and the contact portion 11. [ Further, the bending portion 13, the guide portion 17, and the contact portion 11 may have the same width or may be partially deformed in width as required.

The guide portion 17 limits the compression distance of the contact portion 11 when the connection terminal 10 is pressed. In detail, the guide portion 17 is bent at 90 degrees upward from the base portion 15 and is formed in a direction perpendicular to the PCB 1. As shown in Fig. The guide portion 17 is formed around the base portion 15 so as not to form the bending portion 13 and may be symmetrically formed on both sides. Here, by forming the guide portion 17, it is possible to restrict the compression distance of the connection terminal 10 and prevent the overall shape from being deformed.

However, the present invention is not limited to the drawings, and the guide portion 17 may be formed on only one of the circumferences of the base portion 15. For example, the guide portion 17 may be bent 90 degrees downward from the contact portion 11 and formed in a direction perpendicular to the PCB 1. Alternatively, as shown in FIGS. 5 and 6, the guide portion 17 may be formed at the upper portion of the base portion 15, and may be formed at the lower portion of the contact portion 11. The shape and size of the guide portion 17 are not limited to those shown in the drawings, and can be changed substantially in various ways.

On the other hand, the design specifications of the connection terminal 10 according to the embodiment of the present invention disclosed in the drawings and the like are merely illustrative, and the idea of the present invention is not limited thereto.

Hereinafter, a connection terminal 20 according to still another embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. 5 is a perspective view of a connection terminal 20 according to another embodiment of the present invention, and Fig. 6 is a sectional view of the connection terminal 20 of Fig. In the following embodiments, the same components as those of the above-described embodiment are designated by the same reference numerals and the description thereof is omitted.

The connection terminal 20 includes a contact portion 21 and a base portion 25 and a bending portion 23. The connection terminal 20 has a bending portion 23 between the base portion 25 and the contact portion 21 in a substantially Z- . Further, guide portions 27, 28 and 29 are formed on both sides of the connection terminal 20, respectively.

The base portion 25 is flatly formed to be mounted on the PCB 2 and the contact portion 21 is formed parallel to the base portion 25. [ For example, the base portion 25 and the contact portion 21 are formed of a plate material having a size corresponding to each other, and are formed into a band or a rectangular shape with a predetermined length.

The bending portion 23 is formed to connect one end of the base portion 25 and the other end of the contact portion 21 so that the connection terminal 20 has a Z shape. The bending portion 23 has no bending portion but the portion where the bending portion 23 is connected to the contact portion 21 and the base portion 25 is bent, So that elastic deformation is possible. Further, the contact portion 21 can be compressed in a state parallel to the base portion 25. The width of the bending portion 23 may be the same as or smaller than the width of the base portion 25 and the contact portion 21. [

The guide portions 27, 28 and 29 have a first guide 27 bent upward by 90 degrees from the base portion 25 and formed in a direction perpendicular to the PCB 2, A second guide 28 formed in a direction perpendicular to the PCB 2 and a third guide 29 extending downward from a side where the bending portion 23 is not formed in the contact portion 21. [ The first guide 27 and the second guide 28 contact each other when the connection terminal 20 is compressed or the first guide 27 and the second guide 28 come into contact with each other, (28) may overlap each other. However, the shapes and sizes of the guide portions 27, 28, and 29 are not limited to those shown in the drawings, and may be substantially varied.

According to the embodiments of the present invention, since the connection terminals 20 and 20 are mounted on the PCB 2 and the contact portions connected to the mobile communication devices are formed in parallel, the connection terminals 20 and 20 and the circuit board module The overall thickness can be reduced, and the thickness of the mobile communication device can be made thin and downsized. In addition, by using a bending shape bent at a plurality of positions, it is possible to prevent excessive deformation of the connection terminals 20, 20 and to stably contact the mobile communication device. In addition, since the base portions 25 and 25 have an area larger than a predetermined size, a solder region with respect to the PCB 2 can be secured.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
