Description
本发明涉及一种射频同轴连接器,尤其涉及一种结构简单的射频同轴连接器。
射频连接器在笔记本电脑中用被广泛应用,用于无线数据的传输,该射频连接器连接线缆的一端,另一端连接天线,且该射频连接器插接于电路板上的同轴连接器,对于该射频同轴连接器与线缆的连接方式主要有以下方法:
1.焊接方式,将线缆中心导体与端子焊接连接成一体,实现电连接目的。虽然焊接结构可提高连接可靠性,但生产效率低,成本高,不良率较高,对人员技能及设备要求高。
2.压接方式,藉由端子与线缆的中心导体装入端相反的一侧设计有一压板,与端子装配平面呈一小于90度的夹角,如美国专利第US 6,790,082号揭露的一种射频同轴连接器,当装配时,金属盖体下压时推动端子压板,在盖板压平后,使端子压板将线缆中心导体夹在端子安装平面之间,从而实现与线束的连接。虽然生产工艺性良好,易实现自动化,但当线缆中心导体在被夹紧的过程中,易出现散开,较严重时,对高频信号的传输有一定影响。
另请参考于2014年4月2日公告中国专利第CN203521658U号,其公开了一种线缆连接器,可用于连接一具有芯线的线缆,包括:绝缘本体、端子及遮蔽壳体,所述绝缘本体具有安装部及凸伸安装部一侧的对接部,于对接部凹设有对接腔,安装部设有与对接腔相连通的收容槽;上述端子设有收容于收容槽内可连接芯线的连接部及凸伸入对接腔内的接触部;所述遮蔽壳体设有遮覆于
绝缘本体的安装部外的遮蔽部;所述绝缘本体具有凸伸入收容槽内的弹性臂,该弹性臂位于端子的连接部的外侧,遮蔽部具有顶推弹性臂并挤压端子的连接部与芯线接触的盖板。这种设计的缺点:线束在被夹紧的过程中,易出现散开,即夹持不够稳定,且严重时,对高频信号的传输有一定影响;另外,端子是延伸一对弹性臂,上侧与芯线连接,下侧与对接连接器的端子接触,若插接对接连接器时,端子的连接部会被朝两侧撑开,从而增加上侧与芯线连接的间隙,并影响与芯线连接的稳定性;再者,该现有技术是通过在遮蔽部上冲压一对挤压弹性臂的盖板,不仅破坏了遮蔽壳体的外壳结构,而且影响连接器信号传输的干扰。
鉴于现有技术的上述缺陷,实有必要设计一种改进的射频同轴连接器。

所述盖板13用以挤压导电端子2的连接部21侧面与芯线50接触。所述盖板13包括平板部131和自平板部131凸出的两个凸肋132,所述两个凸肋132分别抵压相应弹性臂211。所述盖板13还包括位于两个凸肋132之间的压线部133,所述压线部133的高度小于凸肋132的高度,以便更好的压接芯线,提供较好的稳定性。平板部131包括连接安装部11的第一平板部134和自第一平板部134向外延伸形成的第二平板部135,所述第二平板部135的宽度小于第一平板部134的宽度。每一凸肋132呈斜角设置,方便盖板13压入安装部内,每一凸肋132包括位于第一平板部134上的第一凸出部136和位于第二平板部135上
的第二凸出部137,所述第一凸出部136的厚度小于第二凸出部137的厚度,所述压线部133位于第二平板135上且位于连个第二凸出部137之间。因芯线的厚度小于带绝缘皮的芯线厚度,所以所述第一平板部134的厚度大于所述第二平板部135的厚度,方便平衡挤压线缆的芯线。所述绝缘本体1的安装部11具有凸伸入收容槽111内的凸起101,所述导电端子2的主体部23两端支撑于该凸起上,且所述平板部131将主体部夹持在凸起101上。
金属壳体3包括柱体部31、自柱体部31一侧向后延伸出的延伸部32和可弯折性地连接在柱体部31另一侧的盖体部33。延伸部32上设有第二卡扣槽321,所述第二定位凸块151***安装至第二卡扣槽321内。柱体部31上设有第一卡扣槽311,所述第一定位凸块141***安装至第一卡扣槽311内,以将绝缘本体1定位在金属壳体3内。柱体部31的中间围设有容置槽310,所述容置槽310将对接部12和柱状部14收容在其内。盖体部33包括主体部331、自主体部311弯折形成的第一折弯部332及自主体部311弯折形成的第二折弯部333。第一折弯332包围在延伸部32外,第二折弯部333包围在线缆51外。
本发明的射频同轴连接器100,导电端子2在芯线50引入一侧设计一对侧向对称的弹性臂211,弹性臂211的受压部214与绝缘本体1的内侧壁112有一间隙113,弹性臂211之间的间距可以让芯线50自由通过,绝缘本体1的绝缘盖板13头部设计有一对带斜角的凸肋132,方便凸肋132***间隙113内。
装配过程及原理:射频同轴连接器100装配好后,将芯线50从连接器的线束引入端***,之后将金属壳体3的盖体部33压下,盖体部33推动绝缘本体1的盖板13下压,到位后,盖板13的凸肋132塞入导电端子2的弹性臂211与绝缘本体1之内侧壁112的间隙113。由于凸肋132的第二凸出部137宽度大于弹性臂211与内侧壁112的间隙113,将推动弹性臂211内缩而与芯线50接触,进
而进一步夹紧芯线50,从而达到连接并夹紧芯线50之目的,实现芯线50与导电端子2的可靠连接。
与现有技术相比,以上结构可以实现与压接式方法相同的线束装配方式,具有良好的工艺性能;其次,导电端子2自由端与芯线50的松脱方向相反,当芯线50被夹紧时,可有效防止芯线50的松脱(芯线50会越拉越紧),具有良好的连接可靠性;再其次,由于采用盖板13上凸肋132塞紧导电端子2与内侧壁112的间隙113的方式,在提供较大的夹持力情况下,对芯线5不会产生附带损伤;另外,由于芯线5在左右及上下4个方向均被有较约束,不易产生发散现象,对高频传输的稳定有利;最后,由于对芯线5的夹持作用是依靠凸肋132与导电端子2之间的相互作用实现,对导电端子2本身的加工精度要求相对低,零件易于生产,并具有结构简单、连接可靠的功效,且具有较好的屏蔽性能。
本发明不局限于上述具体的实施方式,本领域的普通技术人员从上述构思出发,不经过创造性的劳动,所作出的种种变换,均落在本发明的保护范围之内。
