An elastically contactable connecting device is mounted between the antenna contacts so that the antenna and the PCB are electrically connected.

Such a board-mounted connection device is manufactured by pressing and forming a plate-shaped conductive metal. The board-mounted connection device includes a fixing portion fixed to the substrate side, a connection portion directly connected to the external terminal, And an elastic part for imparting elasticity to the elastic member.

In "Antenna connection device for mobile phones" of Korean Laid-Open Patent Publication No. 10-2003-0017915 (Patent Document 1), the structure and installation structure of such a board mounted connection device are disclosed.

1A shows a connection device according to Patent Document 1. As shown in FIG. Referring to FIG. 1A, the connecting device 100 includes a fixing part 110 fixed to a substrate, a connecting part 120 directly connected to an external terminal such as an antenna, and an external terminal connected to the connecting part 120. An elastic part 130 is provided to give elasticity to the connection part 120 when losing.

1B shows a state in which a connection device according to Patent Document 1 is mounted on a substrate. Referring to FIG. 1B, the connecting device 100 is fixed to the substrate 200 through fastening pieces 140 that are bent to a predetermined length downward from both sides of the fixing part 100. In more detail, a hole in which the fastening piece 140 is inserted is formed in the substrate 200, and the connection device 100 includes a fastening part 140 while the fastening piece 140 is inserted into a hole formed in the substrate 200. The 110 is fixed to the substrate 200 through soldering in a state in which it is seated on the surface of the substrate 100.

Thus, in the conventional board | substrate mounting type connection apparatus which concerns on patent document 1, a connection apparatus is provided in the surface of a board | substrate. That is, the fixing part forming the bottom of the connecting device is provided to contact the upper surface of the substrate. This limits the installation height of the connection device. Therefore, there is a limit in minimizing the thickness of the electronic device such as a cellular phone in which the connection device is installed.

In addition, since the entire connecting device is exposed to the outside of the board, contact interference between neighboring parts occurs when mounting other parts on the board, which causes deformation of the connecting device, which in turn causes performance degradation of the connecting device. .

 As such, the surface-mounted connection device fixed directly to the substrate by forming a hole directly in the fixing portion without the fastening piece is disclosed in Korean Utility Model Publication No. 20-0424639 (Patent Document 2) and Korean Patent Publication No. 10-2008-0018600 (Patent Document 3) and Patent Document 3: Korean Unexamined Patent Publication No. 10-2009-0105430 (Patent Document 4) and the like are disclosed in various forms.

However, the substrate-mounted connection device proposed in these patent documents also has a limitation in realizing thinning of electronic devices such as Patent Document 1 because the connection device is provided on the surface of the substrate (surface-mounted connection device). In addition, the problem that the deformation of the connection device occurs as it is.

It is a use state diagram which shows.

2A to 2C, the PCB cut type connection device 10 according to the first exemplary embodiment of the present invention is manufactured by pressing and forming a strip-shaped conductive metal, and the fixing part 100 and the elastic part. The 200, the connection part 400, and the connection part 300 are continuously formed in one piece.

The fixing part 100 is manufactured in the form of a flat plate, and is fixed to be electrically connected to the PCB substrate 20.

As described above, the present invention is fixed in such a way that the connection device 10 is inserted into the mounting hole 21 formed in the PCB substrate 20.

To this end, both side surfaces of the fixing part 100 are formed with side extensions 110 extending wider than the width of the elastic part 200 and the connecting part 300, respectively. In addition, the front surface of the fixing part 100 is formed with a front extension part 120 that extends forward longer than the end of the connection part 300. The lateral extension 110 and the front extension 120 extend in the same plane as the fixing part 100.

The connection device 10 is fixed inside the seating hole 21 through the side extension part 110 and the front extension part 120 of the fixing part 100. The lateral extension 110 and the front extension 120 provide a region in which the fixing part 100 is soldered to the PCB substrate 20.

Specifically, in a state where the connection device 10 is inserted into the seat hole 21 of the PCB substrate 20, the side surface extending portion 110 and the front surface extending portion 120 of the fixing portion 100 are inserted into the mounting holes 21 Is formed on the bottom surface of the PCB substrate 20. The portion where the PCB substrate 20, the side extension 110 and the front extension 120 contact each other is fixed by soldering.

In this regard, the width of the elastic portion 200 and the connection portion 300 should be made smaller than the width of the seating hole 21, the width of the fixing part 100 including both side extension portion 110 is the seating hole ( 21) should be wider than the width. On the other hand, the length of the fixing part 100 including the front extension part 120 may be smaller than the length of the seating hole 21.

On the other hand, in the fixing part 100 in order to increase the adhesion when fixing the soldering in order to secure the firmness on both sides of the extending portion 110 of the fixing part 100, that is, both ends in the width direction of the fixing part 100 Semi-circular fillet 180 is formed.

The elastic part 200 has a predetermined radius of curvature at the rear of the fixing part 100 to form a semi-circular or semi-elliptic shape that is bent upward, and is elastically deformed when connected to the external terminal to the connection part 300, and the connection part when disconnected. (300) serves to restore.

The connection part 300 is a part for connecting with an external terminal, having a predetermined radius of curvature and having a predetermined radius of curvature while being inclined upward at the end of the connection part 400 extending horizontally from the elastic part 200. The end portion thereof extends in the direction toward the fixing part 100. The upper surface of the connection portion 300 is formed with an embossing 310 is made of plating of gold or nickel excellent in electrical conductivity in order to improve the connection performance.

 2D and 2E are diagrams illustrating a top and bottom surfaces of a PCB cut type connector according to a first exemplary embodiment of the present invention mounted on a board.

2C and 2E, the connection device 10 is inserted into the mounting hole 21 with the top surface of the connection portion 300 facing the bottom surface ('A' surface) of the PCB substrate 20. When the connecting device 10 is inserted into the mounting hole 21, the PCB substrate 20 in which the side extension part 110 and the front extension part 120 of the fixing part 100 have the mounting hole 21 is formed. While being caught on the bottom surface of the PCB substrate 20 is in contact with the state.

In this state, soldering is performed on the surface contacted portion, so that the connection device 10 may be fixed to the PCB substrate 20 in a state of being seated in the seating hole 21 of the PCB substrate 20.

At this time, the connection device 10 is mounted so that the connection portion 300 protrudes out of the PCB substrate 20 so that the connection portion 300 can move below a certain height through the connection with the external terminal. Specifically, it is preferable that the connection part 300 is mounted to protrude out of the PCB substrate 20 to a height at which the external terminal does not come into contact with the PCB substrate 20 during the recommended (normal) operation of the connection device (FIG. 2F). Reference).

In other regards, the height of the connection device 10 may vary depending on the height of the seating hole 21. In other words, the height from the fixing part 100 of the connecting device 10 to the upper end of the connecting part 300 may be manufactured differently according to the thickness of the PCB substrate 20.

In the case where the thickness of the PCB substrate 20 is relatively thick, the height of the mounting hole 21 is also increased, and abnormal external force is applied to the connection device 10 as well as during the recommended (normal) operation of the connection device 10. Even if the 300 is excessively pressed, the end of the connection part 300 may be manufactured so high that it may not reach the fixing part 100.

However, when the thickness of the PCB substrate 20 is very thin, the height of the mounting hole 21 is also lowered so that the height of the connection device 10 should be relatively low. In this case, even when the connection device is recommended (normal), the end of the connection part 300 comes into contact with the fixing part 100, thereby preventing the normal functioning of the connection device.

To this end, in the present invention, even when the connection device 10 is mounted on the PCB substrate 20 having a very thin thickness, a means is provided that the end of the connection portion 300 can be normally operated without touching the fixing portion 100 Respectively.

The through-hole 150 through which the end portion of the connection portion 300 passes is formed so as not to contact.

As such, when the connection part 300 is operated, the connection part 300 is moved into the through hole 150 formed in the fixing part 100 so as to move the connection part 300 even if the height of the connection device 10 is not increased. The distance can be increased, and the connection part 300 does not touch the fixing part 100 so that the function of the connection device can be normally implemented.

Hereinafter, an operation in which the PCB cut type connection device according to the first embodiment of the present invention is connected to an external terminal will be described.
