Description

Antenna connector of printed circuit board

The present invention relates to a connector, and more particularly, to an antenna connector of a printed circuit board which is easily removable to be convenient for use.

In general, a connector has a very broad meaning in that it connects something, but a connector used in the electric industry or the electronic industry means a connection element that performs a function of connecting an electrical signal.

The general form of such a connector consists of at least one conductive metal in a housing shaped to connect a plurality of electrical signals through a plurality of wires.

In addition, a connector for connecting to a printed circuit board (hereinafter, referred to as a PCB) of an electronic product has a mainstream form in which the conductive metal part is soldered onto a pattern on the PCB for electrical connection. In the case of a device that transmits and receives a signal wirelessly, an antenna connector for connecting to an antenna is provided.

However, the conventional connector does not have any problem as a conventional connector in the case of simply establishing a fixed electrical connection, but when the other connector needs to be detached from the connector, fine shaking accumulates to damage the soldering state with the PCB. It is easy and has the disadvantage of shortening the life of the connector.

In addition, in the case of a wireless modem, the antenna connector to be connected to the antenna is frequently detached for electrical connection with the antenna, so it is necessary to provide a support member on the antenna connector that can firmly support the shake when detaching.

As such, the fixed state of the antenna connector, which is not robust, may cause noise in the electronic circuit in case of poor contact.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an antenna connector of the PCB so that the support member is built to implement a solid connection with the PCB.

Features of the present invention for achieving the above object is a connector shaft made of a metallic material cylindrical; A conductive shaft formed in the connector shaft in a centrifugal shaft direction, provided with a protruding pin protruding from one side thereof, and a concave pin having a concave pin formed at the other side thereof; An insulating member disposed inside the connector shaft and filled with an insulating material to surround the conductive shaft to insulate the conductive shaft; A screw member having threads formed on an outer diameter of the connector shaft to enable connection with an external connector; A first support member protruding in the other direction of the connector shaft and a first support member protruding to face the first support member to prevent shaking in an upward direction when the PCB is connected to a predetermined position of the PCB; And a support member including a second support member and a third support member positioned below the first and second support members to protrude in the other direction of the connector shaft to prevent shaking in the downward direction.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the appearance of an antenna connector according to the present invention, the antenna connector 10 and the first support member 12 and the second support member 14 to support the shaking in the upward direction, and downward The third support member 16 for supporting the shaking of the, and the protruding pin 18 made of a conductive metal for transmitting and receiving electrical signals is provided.

In addition, the connector shaft 20, which is the main shaft of the antenna connector 10, a screw portion 22 formed to be connected to the rear of the connector shaft while rotating with an external connector, and a synthetic resin form for insulation of the protruding pin 18. The insulating portion 24 is filled with the insulating material of the fixed is provided.

Looking at the antenna connector 10 in the A direction is as shown in FIG.

FIG. 2 is a perspective view of the antenna connector shown in FIG. 1 as viewed from the A direction, in which a concave pin 28 having the same body as the protruding pin 18 of FIG. 1 and having a concave hole in the A side of FIG. have. In this case, the protruding pins and the concave pins may be formed of a material that has conductivity and is capable of achieving electrical signal matching, that is, impedance matching when connected to an external connector.

The antenna connector 10 having the above-described appearance is connected to the PCB as shown in FIG. 3.

3 is a perspective view showing a state in which the antenna connector 10 of the present invention is inserted into the side of the PCB, the shape of the PCB to which the antenna connector is connected is very diverse depending on the type and form of electronic products, The antenna connector can be applied to any kind of PCB.

Meanwhile, an external male connector is connected to the concave pin 28 on the A side, and the protruding pin 18 is configured to be in contact with a printed pattern on the PCB.

According to a preferred embodiment of the present embodiment disclosed as described above has the following advantages.

First, since both the support member in the upward direction and the support member in the downward direction are provided, there is an advantage of extending the life of the product is very robust compared to the conventional antenna connector.

Second, it is easy to attach and detach because the antenna connector is simply inserted into the PCB, and it is convenient for maintenance because there is no need to remove the antenna connector by melting the solder on the PCB during the after-sales service.

Fifth, since the contact point is stable and no noise is generated, the PCB function is stabilized.

Fourth, it is excellent in durability because it is composed of a structure resistant to vibration and shock.
