Description

Technical Field

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

[0002] In today's era of advanced electronic technology, the operating frequency of various devices continues to increase, the integration of internal components is becoming increasingly dense, and the complexity of the electromagnetic environment far exceeds that of the past. The electromagnetic shielding capability of connectors directly affects the anti-interference performance of the entire system. Especially in highly sensitive application scenarios such as new energy vehicles and industrial automation, even weak external electromagnetic pulses can trigger a chain reaction such as signal distortion and mis-triggered control commands. This can lead to abnormal equipment functions or even endanger system safety. Therefore, building a reliable electromagnetic shielding barrier for connectors has become a key technical requirement for improving the stability of electronic devices. However, traditional connectors often lack electromagnetic shielding functions, and the snap-fit ​​connection of the shell can easily damage the shell.

[0003] On the one hand, traditional wire connectors mostly use engineering plastics to make the shell. Although they can meet the requirements of insulation protection and basic structural strength, such materials themselves do not have conductive properties and cannot form a closed electromagnetic shielding circuit. When the connector is in a high-frequency operating state, the internal circuit is easily interfered with.

[0004] On the other hand, the reliability of conventional snap-fit ​​connectors is also a prominent issue. During repeated insertion and removal, the plastic snap-fit ​​structure is prone to developing micro-cracks in critical stress areas due to stress concentration. These cracks gradually expand over time, eventually leading to snap-fit ​​breakage or elastic failure, and the one-piece molded shell is also damaged.

[0005] Therefore, existing connectors need to be optimized in terms of electromagnetic shielding performance and shell connection methods. Utility Model Content

The following is a detailed description of this connector with electromagnetic shielding.

[0025] An electromagnetically shielded connector includes a front shell 100, a connector body 101, and a rear shell 102. The connector body 101 is located at one end of the front shell 100, and the rear shell 102 is located at the other end. Both the front shell 100 and the rear shell 102 can be made of aluminum alloy. A connecting shell 103 is located around the outer periphery of the connector body 101, and a circuit board 104 is located at the bottom of the connecting shell 103. An integrated circuit 105 is located at one end of the rear shell 102, and a shielding ring 106 is located at the other end of the rear shell 102. The shielding ring 106 can... Electromagnetic interference between multiple sets of connecting lines 107 is shielded to avoid distortion of current signals caused by electromagnetic interference, thereby improving the electromagnetic shielding performance of the connector and also improving the reliability of the connector. One end of the shielding ring 106 is connected to multiple sets of connecting lines 107. The top and bottom of the rear shell 102 are provided with first connecting plates 108, and the two sides of the rear shell 102 are provided with second connecting plates 109. One end of the front shell 100 is provided with two sets of first stepped surfaces 110, and the top and bottom of the rear shell 102 are provided with second stepped surfaces 111.

[0026] The top and bottom of the shielding ring 106 are integrally formed with inclined protrusions 112. The two sets of first connecting plates 108 are provided with fixing grooves 113. The two sets of inclined protrusions 112 are locked in the fixing grooves 113. The shielding ring 106 is connected to the rear shell 102 by the cooperation of the inclined protrusions 112 and the fixing grooves 113, which improves the fixing effect of the shielding ring 106 and the rear shell 102 and prevents the shielding ring 106 from moving.

[0027] The shielding ring 106 has a first protrusion 114 integrally formed on the top and bottom. Each of the two sets of first connecting plates 108 has a slot at one end. The two sets of first protrusions 114 are locked in the slots. The slots lock the first protrusions 114 to prevent the shielding ring 106 from moving left and right, thus improving the connection stability of the connector.

[0028] Two sets of second protrusions 115 are integrally formed on both sets of first connecting plates 108. Two sets of first sliding grooves 116 and four sets of second sliding grooves 117 are provided at one end of the front shell 100. The two sets of first sliding grooves 116 correspond to the positions of the two sets of first protrusions 114, and the four sets of second sliding grooves 117 correspond to the positions of the four sets of second protrusions 115. Two sets of first transverse grooves 118 and two sets of second transverse grooves 119 are provided at one end of the front shell 100. The two sets of first sliding grooves 116 communicate with the first transverse grooves 118 and the second transverse grooves 119, and the four sets of second sliding grooves 117... Both are connected to the first transverse groove 118. When the user wants to connect the front shell 100 and the rear shell 102, the first boss 114 and the second boss 115 are aligned with the positions of the first slide groove 116 and the second slide groove 117 respectively, and the rear shell 102 is pushed in. When the first boss 114 reaches the position corresponding to the second transverse groove 119, the rear shell 102 is pushed horizontally so that the first stepped surface 110 and the second stepped surface 111 are in contact. At this time, the first boss 114 will be restricted from moving back and forth by the second transverse groove 119, thus completing the connection between the front shell 100 and the rear shell 102.

[0029] The front shell 100 has multiple sets of protruding ribs 120 integrally formed at one end. The multiple sets of protruding ribs 120 can restrict the connector body 101 to the correct position inside the front shell 100 so that the connector head (not shown in the figure) can be inserted into the connector body 101. The outer wall of the connector shell 103 contacts the multiple sets of protruding ribs 120, and one end of the connector body 101 contacts the front shell 100.

[0030] Both sides of the connecting shell 103 are integrally formed with welding feet 121. The top of the circuit board 104 is connected to two sets of first pads. The two sets of welding feet 121 are respectively welded to the two sets of first pads. One end of each of the two sets of second connecting plates 109 is provided with an opening slot 122. The top of the circuit board 104 is connected to two sets of second pads. The two sets of opening slots 122 are respectively welded to the two sets of second pads. The first pads and the second pads are electrically connected and are both connected to the ground wire, so that the front shell 100 and the rear shell 102 are connected to the ground wire through the welding feet 121 and the opening slots 122, which helps to realize the electromagnetic shielding function. Multiple sets of connecting lines 107 are electrically connected to the circuit board 104.

[0031] A wiring hole is provided at one end of the rear cover 102, and an integrated circuit 105 is installed inside the wiring hole.

[0032] One end of the shielding ring 106 contacts the rear shell 102, and the first stepped surface 110 contacts the second stepped surface 111. The first stepped surface 110 and the second stepped surface 111 can restrict the left and right movement of the front shell 100 and the rear shell 102, prevent gaps in the fit between the front shell 100 and the rear shell 102, improve the fitting accuracy of the connector, and improve the reliability of the connector.
