Description

A wire-end connector assembly with electromagnetic shielding Technical Field

[0001] This utility model relates to the field of connector assembly technology, and more specifically, to a wire-end connector assembly with electromagnetic shielding. Background Technology

[0002] As modern electronic devices develop towards higher frequencies and higher densities, electromagnetic shielding has become a crucial factor restricting the reliability of electronic systems. In fields such as industrial automation and new energy vehicles, connectors, as the core carriers of signal transmission, directly affect the anti-interference capability of the entire system through their electromagnetic shielding performance. When high-frequency signals pass through connectors without electromagnetic shielding, they can generate electromagnetic radiation that interferes with adjacent circuits. In severe cases, this can lead to data errors, signal distortion, or even system crashes. However, traditional connector assemblies have plastic shells that lack electromagnetic shielding, and their snap-fit ​​connection method can easily damage the shell, resulting in damage to the connector assembly.

A top plate 110 is provided at the top of the rear shell 101, a bottom plate 111 is provided at the bottom of the rear shell 101, two sets of elastic elements 112 are provided between the top plate 110 and the bottom plate 111, and baffles 113 are provided on both sides of the rear shell 101.

[0027] One end of the connector 102 is fixedly connected to a mounting shell 104, which may be made of copper alloy. Both sides of the mounting shell 104 are provided with soldering feet 114. The top of the circuit board 105 is provided with two sets of first solder pads 115, which are soldered to the two sets of soldering feet 114 respectively. Both sets of first solder pads 115 are connected to the ground wire in the circuit board 105 to assist in achieving electromagnetic shielding. One end of the mounting cavity 103 is provided with multiple sets of protruding ribs 116, which are in contact with the outer wall of the mounting shell 104. The protruding ribs 116 can connect the mounting shell 104 and the front shell 100, so that the ground wire is connected to the front shell 100 to assist in achieving electromagnetic shielding. One end of the connector 102 is in contact with the mounting cavity 103.

[0028] Both sides of the rear shell 101 are integrally formed with baffles 113. The top plate 110 and the bottom plate 111 are integrally formed with two sets of trapezoidal protrusions 117. The top of the top plate 110 and the bottom plate 111 are both provided with two sets of through holes 118. The positions of the four sets of through holes 118 correspond to the positions of the four sets of trapezoidal protrusions 117. The top and bottom of the two sets of elastic members 112 are respectively inserted into the four sets of through holes 118. The two sets of elastic members 112 can rotate around the through holes 118. When the second bending contact groove 122 on the two sets of elastic members 112 is in contact with the through holes 118, the top and bottom of the two sets of elastic members 112 extend out of the through holes 118, so that the top and bottom of the two sets of elastic members 112 are locked in the square hole 120, so that the position of the rear shell 101 and the front shell 100 is fixed. This fixing method is not easy to damage the front shell 100, increases the service life of the component, and reduces the maintenance cost of the component.

The elastic element 112 is provided with a first bend and two sets of second bends. When the user wants to remove the back cover 101, he pushes the back cover 101 toward the front cover 100. The connecting plate 107 will push the elastic element 112 to rotate, so that the second bend on the elastic element 112 contacts the baffles 113 on both sides of the back cover 101. At this time, due to the restriction of the trapezoidal protrusions 117, the two sets of elastic elements 112 will be compressed, and the part of the two sets of elastic elements 112 that protrudes from the through hole 118 will be retracted. At this time, the square hole 120 will no longer hold the two sets of elastic elements 112. The user can then pull the back cover 101 outward to remove the back cover 101.

[0032] Both sets of baffles 113 are provided with slots 123 at one end, and the circuit board 105 is provided with two sets of second pads 124 at one end. The two sets of slots 123 are respectively soldered to the two sets of second pads 124.
