Abstract: A connector for a DMB antenna comprises an antenna connector and a coaxial connector. The antenna connector includes an antenna coupling unit at one end thereof as well as a cylindrical guide unit, which includes connector pins protruding from the center, at the other end thereof. The cylindrical guide unit is coupled to a coaxial connector by sliding into the inside of the circumference thereof. The cylindrical guide unit comprises plural elastic portions between each of which a gap is placed. Convex stopper protrusions are formed at the end portion of the guide unit. A jack to which a connector pin is connected is placed in the center of the coaxial connector, and the coaxial connector includes stopping grooves into which the stopper protrusions are inserted. An insulating ring for preventing rotation made of a plastic ULTEM material is placed between the cylindrical guide unit and the antenna coupling unit. Since the insulating ring is extended between the cylindrical guide unit and the connector pin, a protecting tube for a jack which encloses the connector pin is formed. A jack insertion groove into which an insulation supporting tube is inserted is formed inside the circumference of the protecting tube. Right and left concave insertion portions which are cut in an arc shape are additionally prepared at both sides in the rear portion of the cylindrical guide unit. The jack is enclosed by the insulation supporting tube, and then inserted into the jack insertion groove. Since left and right convex insertion parts formed inside the circumference of the coaxial connector are coupled with the left and right concave insertion parts, the rotation of the guide unit can be prevented. In this invention, the concave and convex insertion parts, which are coupled by their matching shapes, are formed inside the circumferences of both the coaxial connector and the cylindrical guide unit without an additional component. Therefore, the manufacturing cost can be saved. The insulating ring for preventing rotation, which is used as both an insulating member and an anti-rotation member between the connector pin and the antenna connector, is made of a plastic ULTEM which is extremely hard and very resistant against thermal shrinkage or thermal expansion. Hence, there is no inconvenience in the usage, and the durability of the connector can be extended. Furthermore, noise can be reduced since the antenna is not shaken. Thereby a clearer image can be reproduced on a screen.

Abstract translation: 用于DMB天线的连接器包括天线连接器和同轴连接器。 天线连接器在其一端包括天线耦合单元以及在其另一端包括从中心突出的连接器引脚的圆柱形引导单元。 圆柱形引导单元通过滑入其圆周的内侧而联接到同轴连接器。 圆柱形引导单元包括多个弹性部分，在每个弹性部分之间放置有间隙。 在引导单元的端部形成凸起止动突起。 与连接器销连接的插孔位于同轴连接器的中央，并且同轴连接器包括制动突起插入其中的止动槽。 在圆柱形导向单元和天线耦合单元之间放置用于防止由塑料ULTEM材料制成的绝缘环。 由于绝缘环在圆柱形引导单元和连接器插脚之间延伸，所以形成了用于包围连接器插脚的插孔的保护管。 其中插入绝缘支撑管的插孔插入凹槽形成在保护管的周边内侧。 在圆柱形引导单元的后部的两侧额外准备了被切割成弧形的左凹入插入部分和左侧凹入插入部分。 千斤顶由绝缘支撑管包围，然后插入千斤顶插槽。 由于在同轴连接器的圆周内形成的左右凸形插入部分与左凹形插入部分和右凹形插入部分联接，因此可防止引导单元的旋转。 在本发明中，通过它们的匹配形状连接的凹入和凸出的插入部分形成在同轴连接器和圆柱形导向单元两者的圆周的内部而没有附加的部件。 因此，可以节省制造成本。 用作连接器插脚和天线连接器之间的绝缘部件和防旋转部件的防止旋转的绝缘环由塑料ULTEM制成，该塑料ULTEM非常坚硬且非常耐热收缩或热膨胀。 因此，在使用中没有不便，并且可以延长连接器的耐久性。 此外，由于天线不会晃动，所以可以减少噪音。 由此可以在屏幕上再现更清晰的图像。
