In general, DMB (Digital Multimedia Broadcasting) is a broadcasting service that digitally modulates various multimedia signals such as voice and video to digital receivers, fixed, or portable and vehicle receivers, and delivers CDs and CDs through various DMB receivers such as personal mobile terminals and vehicle terminals. DVD-quality high quality and high quality broadcasting can be enjoyed and is attracting attention as the next generation broadcasting.

In such a DMB receiver, it is well known that the antenna plays an important role in easily receiving a transmission frequency and improving reception sensitivity. Therefore, the DMB receiver has a built-in antenna connection port for attaching and detaching an external antenna for each use. The connection port is usually made of a male connector having a connecting pin for signal transmission and an insulator, and connecting to an external antenna. A female connector having a pin insertion hole is provided to be elastically coupled and separated from each other.

On the other hand, when the reception environment changes due to the nature of the radio wave having a noticeable difference in reception sensitivity depending on the direction and position of the antenna, the user rotates the antenna appropriately through the above-described female / male connector.

However, the conventional antenna connector having the above-described structure is easily rotated by the weight or the external force of the antenna because the female / male connector can be rotated freely with each other, and because the coupling portion of the female connector is vulnerable to external forces due to the characteristics of a thin metal material When frequent rotation and detachment, the coupling part is loosened or cracks are generated due to stress.As a result of contact failure of the male / male connector, not only the reception status of the antenna is poor but also the transmission and reception disturbance due to the electromagnetic noise occurs. There was a problem.

Accordingly, the present invention was devised in view of the above-mentioned problems, and an object of the present invention is to allow the antenna connector to be easily prevented from being damaged or deformed due to frequent rotation and detachment of the antenna. Is to provide.

In order to achieve the above object, the present invention is an antenna connector mounted on an antenna and a PCB board for transmitting and receiving radio frequency such as a DMB receiver, respectively, the hollow type having the first and second rotation preventing grooves formed on the inner circumferential surfaces of both ends thereof. A housing; The housing is fixed to the inside of the housing, provided with an insulator on the inside, and formed a plurality of cutouts to have an elastic force on the outside, and a receiving terminal formed with a protrusion along the end of the inner circumferential surface, one side of the signal is inserted into the inside of the insulator A female connector comprising a pin; Inserted and connected to the receiving terminal of the female connector, provided with a connecting pin coupled to the signal pin through the insulator on the inside and the rotation preventing the mutually coupled to the first anti-rotation groove of the housing and the engaging projection of the female connector on the outer peripheral surface It provides an antenna connector, characterized in that consisting of a male connector including an insertion terminal formed with a projection and a locking groove, respectively.

In addition, in describing the present invention, when it is determined that the detailed description of the related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is an exploded perspective view of an antenna connector according to an exemplary embodiment of the present invention, FIG. 2 is a cross-sectional view illustrating a coupling state of FIG. 1, FIG. 3 is an enlarged cross-sectional view of a main portion II-II of FIG. 2, and FIG. 4 is FIG. An enlarged cross-sectional view of the IV-IV main part of FIG. 4, the antenna connector 100 according to the embodiment of the present invention, as shown in FIGS. 1 to 4, includes a housing 110, a female connector 120, and a male connector 130. It is done roughly.

First, the housing 110 is to protect the female / male connectors 120 and 130 coupled to each other from external forces, and to prevent rotation between the female and male connectors 120 and 130, and is formed in a hollow shape and its longitudinal direction. First and second anti-rotation grooves 111 and 112 are formed on the inner circumferential surfaces of both ends thereof.

The housing 110 simultaneously serves to prevent the end of the receiving terminal 121 of the female connector 120 from being loosened or deformed by frequent rotating and detaching operations between the female and male connectors 120 and 130. That is, since the end of the receiving terminal 121 inserted into the housing 110 causes interference with the housing 110 at a predetermined range or more when the antenna A is rotated or removed, the storage terminal 121 is excessively opened. Will be limited.

Here, the first anti-rotation groove 111 is formed in a polygonal surface, the second anti-rotation groove 112 is preferably formed with a plurality of irregularities along the inner circumferential surface.

The female connector 120 is mounted to an antenna for transmitting and receiving radio frequencies such as a DMB receiver, and a receiving terminal made of a conductive material to the outside of the insulator 124 into which the connecting pin 134 of the male connector 130 is inserted and coupled ( 121 is provided, one side is inserted and coupled to the inside of the insulator 124, the other side is provided with a signal pin 125 for transmitting the signal to the antenna (A) to be elastically rotatable.

And the connection groove 126 is formed at the end of the signal pin 125 to be inserted into the insulator 124, the end of the signal pin 125 in the opposite direction to the end formed with the connection groove 126 is the antenna (A) ) Is rotatably connected.

Here, the insulator 124 is made of a material such as PTFE, and when the female connector 120 is coupled to the housing 110, the insulator 124 is inserted into the second rotation preventing groove 112 of the housing 110 to be inserted into the female connector 120. And the housing 110 to maintain a firmly coupled state without mutual flow.

In addition, the engaging protrusion 122 is formed along the inner circumferential end of the receiving terminal 121, and the quick and easy detachment and stable coupling of the female / male connectors 120 and 130 along the longitudinal direction of the receiving terminal 121. A plurality of cutouts 123 are formed. Therefore, when the insertion terminal 131 of the male connector 130 is inserted into the receiving terminal 121 of the female connector 120, the end of the receiving terminal 121 divided into a plurality by the cutout 123 described above. Is elastically open and close to the outer circumferential surface of the insertion terminal 131, so the coupling between the female / male connectors 120 and 130 is made tight and easy.

The male connector 130 is mounted on the PCB board of the DMB receiver, and the insertion terminal 131 of the conductive material is protruded to one side of the main body having a plurality of fasteners for fixing the connection with the circuit of the PCB board at the bottom. On the inside of the insertion terminal 131, a connection pin 134 is coupled to the signal pin 125 through the insulator 124 of the female connector 120.

And the outer circumferential surface of the insertion terminal 131 and the anti-rotation protrusion 133 so that the first anti-rotation groove 111 of the housing 110 and the engaging projection 122 of the receiving terminal 121 can be mutually coupled. Locking grooves 132 are formed respectively.

Here, the anti-rotation protrusion 133 is preferably formed in a polygonal surface.

Accordingly, when the female / male connectors 120 and 130 are coupled to each other, the end of the receiving terminal 121 elastically opens outward and the locking protrusion 122 formed along the inner circumferential surface thereof enters the outer circumferential surface of the insertion terminal 131. When positioned on the same line as the locking groove 132, the end of the receiving terminal 121 is returned to its original state, so that the locking protrusion 122 and the locking groove 132 are in close contact with each other to maintain a firm and stable coupling state. .

In addition, the first anti-rotation groove 111 of the housing 110 is mutually coupled with the anti-rotation protrusion 133 of the male connector 130, the second anti-rotation groove 112 of the housing 110 is a female connector ( The interference between the insulator 124 provided on the outer circumferential surface of the signal pin 125 of the 120 is mutually interference fit to prevent each rotation completely.

Here, the outer diameter of the insertion terminal 131 is preferably formed to be slightly smaller than or the same as the inner diameter of the receiving terminal 121.

In addition, according to the application of the present invention, of course, the female / male connectors (120, 130) may be installed to be located opposite to each other. That is, the female connector 120 may be mounted on the PCB and the male connector 130 may be mounted to be connected to the antenna A.

Referring to the operation state according to the embodiment of the present invention configured as described above are as follows.

First, the insertion terminal 131 of the male connector 130 mounted on the DMB receiver or the like is inserted into the housing terminal 121 of the female connector 120 mounted on the antenna A in a state coupled with the housing 110. In this case, the locking protrusion 122 formed on the receiving terminal 121 is elastically opened by the cutout 123 and is positioned on the same line as the locking groove 132 formed on the outer circumferential surface of the insertion terminal 131. It is firmly adhered to each other while returning to the original state by the restoring force.

Thereafter, even if the user rotates the antenna A in a desired direction, the female / male connectors 120 and 130 are not rotated because they are firmly fixed by the housing 110, and the signal pin 125 is centered. Only the combined antenna (A) is to rotate. Therefore, even in frequent rotation of the antenna (A) it is possible to maintain a good coupling state without damage and deformation of the male / male connectors (120, 130).
