Description

RF Connector for Board Connection

The present invention relates to an RF connector for board connection, and more particularly, to an PCB connector for board connection that allows the connector interface to be rotatable and to be easily fastened even when the position of the connector is not accurately understood. .

In general, RF communication connectors have various structures in which coaxial cables can be easily and tightly coupled to terminals. These RF communication connectors are intended to be fastened to terminals provided in a largely easy-to-view enclosure, and when the connectors and terminals are provided on two boards respectively, the positions of the connectors and terminals are not accurately checked by the boards. It will take longer to combine.

In particular, it is very difficult to couple the connector and the terminal corresponding to the connector with the plurality of connectors provided on one board and the plurality of terminals provided on the other board so that the two boards are arranged up and down, which requires a lot of work time. In case of applying excessive force, the pin of the connector is damaged and a bad signal connection cannot be made.

When such a failure occurs, the work is delayed because of the need to replace the connector having a damaged pin, there was a problem that is expensive.

In view of the above problems, in the structure in which the board and the board are connected to each other via an RF connector, a method that can be stably fastened even when there is a slight position difference between the connector interface by rotating the connector has been proposed. .

As such an example, a connector for surface mounting of a printed circuit board disclosed in Korean Patent No. 10-0945113 (Registration date February 23, 2010) has a connector pin having a connector pin having a connection groove in an upper portion thereof. The pin cutting groove is provided in the configuration to allow the pins of the mating connector to be inserted more easily by giving a difference in tolerance due to the pin cutting groove.

However, the registered patent as described above is not seen as a structure that can easily facilitate the connector coupling in the state that the naked eye can not be confirmed only by having a cutout groove on the outside of the connection groove of the pin inserted into the insulator.

This is described as a rotation in the detailed description of the patent, but this can be seen as the improvement of the tolerance due to the elasticity of the insulator and the cutting groove of the pin, not substantially the rotation.

Therefore, the conventional RF connector for connecting the substrate and the substrate does not have a rotation, there was a problem that can not provide a stable connector connection when the substrate and the substrate is impossible to check the naked eye.

In addition, the registered patent has a structure in which the play may occur due to the elasticity of the incision groove and the insulator on the left and right, but the play does not occur at the top and bottom, and thus, when the excessive coupling force is applied, the inserted pin is bent. Damage may also occur.

An object of the present invention for solving the above problems is to secure the swivelability of the interface in the RF connector connecting the board and the board, to facilitate the coupling of the connector that can not be confirmed with the naked eye The present invention provides an RF connector for board connection.

In addition, the present invention is to provide an RF connector for board connection that can provide rotational ability in the vertical direction.

In order to achieve the above object, the present invention provides a PCB connector for connecting a connector, the connector portion being fixed to a first substrate and supported by a spring provided inside, including an interface portion which rotates at an angle of up and down flow and 360 degrees; It is fixed to the second substrate, and includes a terminal unit for inserting and fixing the upper portion of the interface.

According to the present invention, a spring is provided to the RF connector to provide a restoring force to its original state in a compressed state up and down, and an interface supported by the spring and rotatable in a 360-degree direction is provided so that the interface is rotated. There is an effect that can be more easily combined with the terminal.

In addition, the present invention can be rotated in the vertical direction by the spring, even if the excessive force is applied when the two substrates have the effect of preventing the interface portion is damaged through compression and restoration of the spring.

First, the connector unit 100 is installed in the through hole of the first substrate 1, and the terminal unit 200 coupled to the connector unit 100 is rotatably coupled to the tab-type through hole on the second substrate 2. .

The connector part 100 and the terminal part 200 serve to couple the first substrate 1 and the second substrate 2 to each other regardless of their names. The first substrate 1 or the second substrate 2 may be a communication enclosure. That is, the present invention can be applied to the combination of the enclosure and the substrate or the combination of the substrate and the substrate.

That is, the RF signal of the substrate may be transmitted to the outside of the enclosure in an insulated state from the enclosure, or the external RF signal may be transmitted to the substrate in the enclosure.

The connector unit 100 includes a lower case 120 fixed to a hole of the first substrate 1, and an upper case 130 positioned at an upper side of the lower case 120 and providing an accommodation space therein. Include.

A pin 170 insulated by the insulator 150 is provided inside the lower case 120. A portion of the lower coupling portion 112 of the interface unit 110 is inserted and fixed to the upper side of the pin 170, and is fixed in a rotatable state.

A connection relationship between the lower coupling part 112 of the interface unit 110 and the pin 170 will be described in more detail later.

A spring 140 is provided at an upper side of the lower case 120. The spring 140 has a restoring force in a compressed state in a compressed state, and a ring-shaped spring cap 160 is provided on an upper portion of the spring 140.

When the spring cap 160 is tilted according to the rotation of the interface unit 110, downward force acts along the tilting direction, and the spring 140 is compressed by the downward force. The flow or rotation of the interface unit 110 is enabled.

The upper case 130 and the lower case 120 serves to guide the position of the spring 140, the upper case 130 is bent so that the upper side has a predetermined curvature, the interface unit In addition to preventing the departure of the 110 is supported to enable a smooth flow.

The aforementioned insertion groove 171 of the pin 170 is a groove through which the lower coupling portion 112 of the interface unit 110 can be press-fitted from the upper side. The lower coupling portion 112 has a spherical end, and the lower coupling portion 112 is rotated in a state where an end of the lower coupling portion 112 is inserted into a groove provided on the side of the insertion groove 171.
