本实用新型是一种线缆电连接器，尤其指一种涉及具有电磁屏蔽作用的线缆电连接器。The utility model relates to a cable electrical connector, in particular to a cable electrical connector with electromagnetic shielding effect.

与本实用新型有关的线缆电连接器请参阅图1、图2，现有线缆电连接器包括绝缘本体 1、导电端子 2、电路板 3、第二屏蔽构件 4、第一屏蔽构件 5、线缆 6、上壳体7以及下壳体8等，其中绝缘本体1具有对接端11及结合端13，导电端子2具有端子对接端及端子结合端22，电路板3设有导电线路30，其两端分别是第一导接部31及第二导接部32，且第一导接部31与导电端子2的端子结合端22焊接结合，第二导接部32则与线缆6的导线(未图示)焊接结合。第一屏蔽构件5包覆在绝缘本体1的结合端13，并屏蔽导电端子2、电路板3及部分线缆6等，其在绝缘本体1的对接端11方向凸设有抵触片50，第二屏蔽构件4包覆在绝缘本体1的对接端11，其在绝缘本体1的结合端13方向凸设有抵接部40和凸缘41。Please refer to Figure 1 and Figure 2 for the cable electrical connector related to the present utility model.

The two shielding members 4 cover the abutting end 11 of the insulating body 1 , and are provided with an abutting portion 40 and a flange 41 protruding in the direction of the joint end 13 of the insulating body 1 .

由于第一屏蔽构件5的抵触片50及第二屏蔽构件4的抵接部40的尺寸均很小，其弹性和强度有限，两者在该线缆电连接器检测时弯折过程极易相互脱离或断裂，而无法保持永久的电性连接。另外，现有线缆电连接器的导电端子2的结合端22是由一弧状曲面与电路板3的第一导接部31作点接触或线接触后再进行焊接的，因此焊接面积小，焊接不牢，在线缆电连接器插拔使用过程中易相互分离。再者，绝缘本体1的两侧面为一平面，其组入上、下壳体7、8后不易准确定位。因此，现有线缆电连接器确有改进的必要。Due to the small size of the resisting piece 50 of the first shielding member 5 and the abutting portion 40 of the second shielding member 4, their elasticity and strength are limited, and the bending process of the two during the detection of the electrical cable connector is very easy to interact with each other.

In addition, the joint end 22 of the conductive terminal 2 of the existing cable electrical connector is welded after point contact or line contact with the first conductive part 31 of the circuit board 3 by an arc-shaped curved surface, so the welding area is small, The welding is not firm, and it is easy to separate from each other during the plugging and unplugging of the cable electrical connector. Furthermore, the two sides of the insulating body 1 are planes, and it is not easy to locate them accurately after they are assembled into the upper and lower housings 7 and 8 . Therefore, it is necessary to improve the existing electric cable connector.
