Description

Technical Field

[0001] This application relates to the field of connector technology, specifically to a male connector. Background Technology

[0002] Currently, waterproof 6-pin horizontal HMTD (Heavy-duty Modular Terminal Block Connector) products on the market generally suffer from a significant design flaw: they lack a shielded back cover. From a technical standpoint, during the transmission of 10Gbps high-speed signals, the shielded back cover plays a crucial role in ensuring good electromagnetic compatibility (EMC). The absence of this shielded back cover in existing products leads to easy electromagnetic signal leakage and easier intrusion of external electromagnetic interference, severely impacting the connector's EMC shielding performance during signal transmission and failing to meet relevant industry standards and practical application requirements. This not only limits the product's application in scenarios with high electromagnetic environment requirements but may also trigger a series of malfunctions caused by signal interference, affecting the stability and reliability of the entire system. Utility Model Content

[0003] The purpose of this application is to provide a male connector that can solve the problem that the lack of a shielding cover in current connectors seriously affects the EMC shielding performance of the connector when transmitting signals, and fails to meet the relevant industry standards and practical application requirements.

[0004] To address the aforementioned issues, this application provides a male connector having intersecting first and second directions. The male connector includes: a main shielding shell having a mating end and a rear end in the first direction; the main shielding shell includes at least one first receiving cavity and at least one second receiving cavity, both extending along the first direction and arranged along the second direction; a first terminal assembly extending from the rear end into the first receiving cavity and connected to the main shielding shell along the first direction; a second terminal assembly extending from the rear end into the second receiving cavity and connected to the main shielding shell along the first direction; a first shielding rear cover extending from the first receiving cavity toward the second receiving cavity in the second direction and connected to the main shielding shell, the first shielding rear cover being located on the side of the first terminal assembly away from the main shielding shell in the first direction; and a second shielding rear cover extending from the first receiving cavity toward the second receiving cavity in the second direction and connected to the main shielding shell, the second shielding rear cover being located on the side of the second terminal assembly away from the main shielding shell in the first direction.

[0005] The male connector of this application has a first shielding cover on the side of the first terminal assembly away from the main shielding shell, and a second shielding cover on the side of the second terminal assembly away from the main shielding shell. The first and second shielding covers reduce the influence of electromagnetic interference, protect the integrity of the signal of the male connector, ensure the stability and reliability of the data transmission of the male connector, improve the EMC shielding performance of the male connector, and especially enable the male connector to meet the requirements of 10Gbps high-speed transmission performance.

[0006] This application improves the connection stability between the first shielding back cover and the main shielding shell through interference cooperation between the first protrusion on the first shielding back cover and the first sliding groove on the main shielding shell, resulting in a relatively simple and compact structure. Similarly, it improves the connection stability between the second shielding back cover and the main shielding shell through interference cooperation between the second protrusion on the second shielding back cover and the second sliding groove on the main shielding shell, resulting in a relatively simple and compact structure.

[0031] The main shielding shell 1 has at least one protruding rib structure (not shown in the figure) inside, which is used to interfere with the first terminal assembly 2. Specifically, the protruding rib structure is used to interfere with the first insulating member 22 of the first terminal assembly 2, thereby connecting the first terminal assembly 2 to the main shielding shell 1.

[0032] Please see Figures 2-5 The first terminal 21 includes a first mating portion 211 and a first electrical connection portion 212.
