具体实施方式
以下结合实施例和附图对本发明进一步说明。
本发明涉及一种电缆用线对线连接器，用于将两段或两段以上的电缆连接为一体。在以下有关本发明各实施例的叙述中，本发明以电缆用线对线连接器用于连接两段电缆为例说明。
本发明的线对线连接器可适用连接各种形式的电缆。例如，每段电缆包括内导体及包覆在内导体之外的绝缘套。又如，每段电缆包括内导体和外导体内导体和外导体之间设置有绝缘体。绝缘体用于防止内导体和外导体电连接，并使两者保持同轴，形成一同轴电缆。。外导体之外还包覆有一层绝缘套。内导体为金属材料制成的金属柱体。外导体为金属网，作为屏蔽材料，防止外界电磁波对内导体的电流输送产生不利影响。
本发明中的第一电缆与第二电缆结构相同，为说明方便，对于其相同的结构采用了不同的命名。本发明中的第一外壳与第二外壳结构相同，为说明方便，对于其相同的结构采用了不同的命名。本发明中的第一转接管与第二转接管结构相同，为说明方便，对于其相同的结构采用了不同的命名。
实施例1
如图1至图3所示，本发明的连接器用于将两段电缆，例如第一电缆81和第二电缆86，线对线地连接。在图4A所示的示例中，第一电缆81包括第一内导体82和第一外导体83。第一内导体82与第一外导体83之间设置有第一绝缘体84，用于防止第一内导体82与第一 外导体83电连接并保持两者同轴。例如，第一电缆81为一同轴电缆。第一外导体83之外还包覆有第一绝缘套85。第一内导体82为金属材料制成的金属柱体。第一外导体83为金属网，作为屏蔽材料，防止外界电磁波对第一内导体82的电流输送产生不利影响。在图4B所示的示例中，第二电缆86包括第二内导体87和第二外导体88。第二内导体87与第二外导体88之间设置有第二绝缘体89，用于防止第二内导体87与第二外导体88电连接并保持两者同轴。例如，第二电缆86为一同轴电缆。第二外导体88之外还包覆有第二绝缘套881。第二内导体87为金属材料制成的金属柱体。第二外导体88为金属网，作为屏蔽材料，防止外界电磁波对第二内导体87的电流输送产生不利影响。
如图1至图3所示，电缆用线对线连接器，包括第一外壳10、第二外壳20和连接管30。第一外壳10和第二外壳20可分别连接在连接管30一端。在图中所示的示例中，第一外壳10设置有第一凸肩12。第一凸肩12上设置有沿轴向贯穿的第九通孔(图中未示出)。第二外壳20设置有第二凸肩21。第二凸肩21上设置有沿轴向贯穿的第八通孔(图中未示出)。连接管30设置有分别与第九通孔和第八通孔位置相对的内螺纹孔(图中未示出)。部分螺钉33分别穿过第八通孔与内螺纹孔33螺纹配合、部分螺钉33分别穿过第九通孔与内螺纹孔33螺纹配合，将第一外壳10及第二外壳20与连接管30可拆卸连接。第一外壳10外周与连接管30内壁之间、第二外壳20外周与连接管30内壁之间分别设置有一个第一密封圈13。
电缆用线对线连接器组件还可通过第一外壳10和第二外壳20分别与第一电缆81和第二电缆86的一端连接。第一外壳10具有允许第一电缆81穿过的第一通孔11。第一通孔11沿第一外壳10轴向贯穿第一外壳10。在如图3所示的示例中，第一电缆81穿过的第一通孔11。第一电缆81与第一外壳10内壁之间设置有第二密封圈14。第一电缆81的连接端部分从第一外壳前端101穿出第一通孔11，并延伸至第一外壳前端101之外，用于与第二电缆86电连接。
在图3和图6所示的示例中，第一电缆81的连接端部分安装有第一转接管40。第一转接管40具有自一端起延伸贯穿至另一端的第一管腔41。第一电缆81的第一绝缘体84和第一内导体前端部821穿过第一转接管40中的第一管腔41。第一内导体82与第一转接管40在径向通过第一绝缘体84隔开，不产生电接触。第一外导体前端831设置在第一转接管后端402的外周，并与第一转接管后端402压接。还可以设置一压接套43，套装在第一外导体83外周。第一外导体83位于压接套与转接管40之间，利用压接将三者压接连接。又，第一转接管40可由金属导电材料制成。第一外导体83与第一转接管40相接触，实现电连接。
第一转接管40上设置有第一法兰42。第一法兰42设置在第一转接管40上且突出于第一 转接管40。当第一转接管40与第一外壳10安装在一起后，第一转接管后端402插置于第一外壳10上的第一通孔11内。第一法兰42大于第一通孔11，第一法兰42沿轴向抵靠在第一外壳10端部且位于第一通孔11之外。当第一法兰42抵靠在第一外壳10上时
Figure PCTCN2014000848-appb-000001
第一转接管40受到第一外壳10阻挡而无法再向左移动。
在如图3所示的示例中，第一外壳10设置在连接管30的一端，如图3中的左端。如图8所示，连接管30设置有贯穿的第四通孔34。第四通孔内壁35设置有突出的第六台阶36。第六台阶36突出于第四通孔内壁35。第一法兰42被夹持于第一外壳10与第六台阶36之间。当第一外壳10与连接管30固定安装后，第一转接管40通过第一法兰42在第一外壳10与第六台阶36左端之间定位并固定。由于第一转接管40与第一外导体前端831之间压接连接，第一电缆81在插拔方向相对第一外壳10，或电缆用线对线连接器组件，实现定位和固定。
同时，第一外导体83与第一转接管40之间形成电连接。在本发明的一个示例中，第一外导体83、第一转接管40组成整个电缆用线对线连接器组件的屏蔽结构。第一电缆81的第一内导体前端821还连接有连接端子。第一内导体82和连接端子可以各种方式相互固定，并实现电连接。在如图所示的示例中，连接端子为公端子51，公端子51包括设置在其后部的第二容腔52。第一内导体前端821伸入公端子51的第二容腔52内，利用压接方式使公端子51与第一内导体82连接。公端子51还包括设置在其前部的一周向插接外配合面511，用于配合连接母端子。
如图3、图9、图10和图11所示，公端子51外套装有第一端子隔离套60。第一端子隔离套60一端与第一转接管40的另一端连接。其连接方式可以是插接或者螺纹连接或者其它常规连接方式。本发明的一个优选示例中，第一端子隔离套后端602与第一转接管前端401螺纹连接。第一端子隔离套外壁67设置有第一台阶61。第一台阶61突出于第一端子隔离套外壁67。如图3所示，当第一端子隔离套60与第一转接管40相互连接后，第一端子隔离套60的第一台阶61沿径向突出于第一转接管40，因此，第一台阶61沿轴向抵靠在第一转接管前端401而无法进入第一管腔41内。第一端子隔离套60由此可相对第一外壳10在插接方向定位并固定。
第一端子隔离套60具有贯穿的第二通孔62，用于容纳相互连接的公端子51与第一内导体82。部分公端子51延伸出第二通孔62之外，与对配的连接端子，如对配的母端子，插接。
第一端子隔离套60的第二通孔内壁63设置有第二台阶64，第二台阶64沿径向突出于第二通孔内壁63。第二台阶64既可以沿第二通孔内壁63圆周方向设置一周，也可以沿圆周方 向间隔设置多个。公端子51设置有凹槽53。凹槽53与第二台阶64位置相对。每个第二台阶64嵌入一个凹槽53内。利用第一台阶64与凹槽53相配合，第一端子隔离套60与公端子51在插接方向相互定位并固定。如上所述，由于第一端子隔离套60相对第一外壳10在插接方向定位并固定，公端子51在插接方向相对第一外壳10也被定位并固定，以便插接操作。
本发明的一个优选示例中，第一端子隔离套60端部设置有多个沿轴向延伸一定长度的通槽65。多个通槽65沿圆周方向分布，在第一端子隔离套60端部形成多个第一弹片66。每个第一弹片66均具有一定的弹性。第二台阶64位于第一弹片66上。通过设置第一弹片66，并将第二台阶64设置在第一弹片66上，当第一端子隔离套60套装在公端子51上时，公端子51可使第一弹片66产生弹性变形，方便安装。当凹槽53与第二台阶64位置相对时，第一弹片66可自动复位，使第二台阶64嵌入凹槽53内。
公端子51端部还可拆卸安装有保护套54。保护套54套装在公端子前端511可防止公端子51在装配中受碰撞而损坏。保护套54可制成为绝缘套，以防止人体接触公端子51而发生触电危险。90
尽管图中所示及如上所述的连接端子51为一公端子，连接端子51也可设置呈对配的母端子，如下文所述的母端子55。相应地，第一端子隔离套60可制成类似如下所述的第二端子隔离套70的结构。
如图3所示，本发明电缆用线对线连接器组件的第二外壳20与上述第一外壳10的结构相同或类似。第二外壳20与第二电缆86的连接方式和结构类似于上述第一外壳0与第一电缆81的连接方式和结构。如图中所示，第二外壳20具有允许第二电缆86穿过的第五通孔22。第五通孔22沿第二外壳20轴向贯穿第二外壳20。第二电缆86穿过第五通孔22，并延伸至第二外壳前端201之外，用于与第一电缆81电连接。
在图3所示的示例中，第二电缆86的连接端部分安装有第二转接管90。第二转接管90具有自一端起延伸贯穿至另一端的第二管腔91。第二电缆86的第二绝缘体89和第二内导体87前端部穿过第二管腔91。第二内导体87与第二转接管90不接触。第二外导体88与第二转接管后端902压接。优选地，第二电缆86的连接端部分可套设有一压接套43压接套43套装在第二外导体88外周，将第二外导体88夹持于压接套与第二转接管90之间，利用压接将三者连接。又，第二转接管90可由金属导电材料制成。第二外导体88与第二转接管90实现电连接。
如图3、图7所示，第二转接管90上设置有第二法兰92。第二法兰92设置在第二转接管90上且突出于第二转接管90。当第二转接管90和第二外壳20安装在一起后，第二转接管后端902插置于第二外壳20上的第五通孔22内。第二法兰92大于第五通孔22，第二法兰92沿轴向抵靠在第二外壳20端部且位于第五通孔22之外。当第二法兰92抵靠在第二外壳20上时，第二转接管90受到第二外壳20阻挡而无法再向右移动。
在如图3所示的示例中，第二外壳20连接在连接管30的一端，如图3中的右端。第二转接管90上的第二法兰92夹持于第二外壳20与连接管30内第六台阶36右端之间。当第二外壳20与连接管30固定安装后，第二转接管90通过第二法兰92在第二外壳20与第六台阶36右端之间定位并固定。由于第二转接管90与第二外导体前端881之间压接连接，第二电缆86在插拔方向相对第二外壳20，或电缆用线对线连接器组件，实现定位和固定。
同时，第二外导体88、第二转接管90之间形成电连接。在本发明的一个示例中，第二外导体88、第二转接管90组成整个电缆用线对线连接器组件的屏蔽结构。
如图3、图12、图13和图14所示，第二电缆86的第二内导体前端871还连接有母端子55。第二内导体87和母端子55可以各种方式相互固定，并实现电连接。在如图所示的示例中，母端子55包括第三容腔56。第二内导体前端871伸入母端子55的第三容腔56内，利用压接方式使母端子55与第二内导体87连接。母端子55还包括设置在其前部的一周向插接内配合面551，用于配合连接公端子。
母端子55外套装有第二端子隔离套70。第二端子隔离套70具有贯穿的第六通孔72，用于容纳母端子55和第二内导体87。第二端子隔离套后端702与第二转接管前端901连接。其连接方式可以是插接、螺纹或其它形式的连接。本发明的一个优选示例中，第二端子隔离套70与第二转接管90螺纹连接。第二端子隔离套外壁74设置有第三台阶73。第三台阶73突出于第二端子隔离套外壁74，且突出于第二转接管90。因此，第三台阶73沿轴向抵靠在第二转接管90端部而无法进入第二管腔91内。第二端子隔离套70由此可相对第二外壳20在插接方向定位并固定。
第二端子隔离套70上的第六通孔72具有一内壁75。该内壁75上设置有第四台阶76，第四台阶76沿径向突出于第六通孔内壁75。第四台阶76既可以沿第六通孔内壁75圆周方向设置一周，也可以沿圆周方向间隔设置多个。本发明的一个优选示例中，第二端子隔离套70端部设置有多个第七通孔77，多个第七通孔77沿圆周方向分布。第七通孔77与第六通孔72相通。每个第七通孔77内设置有一个第三弹片78，第三弹片78均具有一定的弹性。第四 台阶76位于第三弹片78上。母端子55设置有卡槽57。卡槽57与第四台阶6位置相对。每个第四台阶76嵌入一个卡槽57内。利用第四台阶76与卡槽57相配合，第二端子隔离套70与母端子55在端部连接，从而确定母端子55轴向位置，并对母端子55提供径向的辅助支撑。通过设置第三弹片78，并将第四台阶76设置在第三弹片78上，当第二端子隔离套70套装在母端子55上时，母端子55可使第三弹片78在径向产生弹性变形，第四台阶76则随第三弹片78径向外移，从而方便安装。当卡槽57与第四台阶76位置相对时，第三弹片78可自动复位，使第四台阶76嵌入卡槽57内，母端子55随即被轴向定位。
母端子55前端551沿轴向缩入第二端子隔离套70内，并被第二端子隔离套70包覆，可防止人体接触母端子55而发生触电危险。
连接管30的第四通孔34内设置有屏蔽套管37。屏蔽套管37两端分别抵靠在第一转接管20和第二转接管90上，并与两者接触连接，形成一连续的屏蔽结构，对本发明的线对线连接器组件进行屏蔽保护。屏蔽套管37设置在公端子51与母端子55外周，与公端子51、母端子55均不接触。第一端子隔离套60和第二端子隔离套70进一步在屏蔽套管37和公端子51、母端子55之间进行屏蔽保护。第一外导体83和第二外导体88通过第一转接管20、屏蔽套管37和第二转接管90电连接。
根据本发明的又一实施例，连接管30的第四通孔34内可涂装一屏蔽层，或者连接管30由屏蔽材料制成，因而无需增设另外的屏蔽套管37。
实施例2
本发明的线对线连接器组件还可适用于不带外导体及绝缘体的电缆，即非同轴电缆。例如，第一电缆81包括第一内导体82和包覆在第一内导体82之外的第一绝缘套35。第二电缆86包括第二内导体87和包覆在第二外导体88之外的第二绝缘套881。
在本实施例中，第一转接管20和第二转接管90可分别与直接第一绝缘套85和第二绝缘套881连接。而且第一转接管20、第二转接管90均无需用金属屏蔽材料制成，本实施例可以省略实施例1中的屏蔽套管37。
本发明中的实施例仅用于对本发明进行说明，并不构成对权利要求范围的限制，本领域内技术人员可以想到的其他实质上等同的替代，均在本发明保护范围内。
