Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a high-voltage male connector. Background Technology

[0002] Connectors, also known as mating parts, are key components in electronic devices, automotive electronics, and communication equipment that enable signal or power transmission. They are typically used in pairs, consisting of male and female connectors, which are plugged into each other to form an electrical connection. The male connector includes a housing and terminals. The terminals pass through the housing and form solder ends and plug ends at both ends of the housing, respectively. The solder ends are used to connect to external devices. The housing has slots corresponding to the plug ends. However, in existing connectors, the solder ends of the terminals are mostly exposed or only rely on simple protection from the edge of the housing, lacking targeted reinforcement protection. Furthermore, during installation, glue is often injected to fix the housing and terminals. However, existing technologies suffer from large gaps between the housing and terminal mounting holes, resulting in poor sealing performance and glue overflowing to the solder ends. To compensate for these defects, additional structures are often required, leading to complex mold structures and low production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a high-voltage male connector that offers higher overall strength and better sealing while maintaining a simple structure.

[0004] To achieve the above objectives, this utility model provides a high-voltage male connector, including a housing and terminals. One end of the terminal is provided with a soldering end corresponding to one end of the housing, and the other end of the terminal is provided with a plug-in end. The housing has a mounting hole for the terminal to pass through and a slot located at the other end. A protective sleeve is provided on the terminal, including an extension and a connecting portion. The extension wraps around the outside of the soldering end and extends to near the end of the soldering end. The connecting portion is located at the mounting hole. A sealing gasket is also provided at one end of the housing to cover the connection portion and the housing.

[0005] The advantages of the above technical solution are as follows: By setting a sheath with an extension and a connecting part on the terminal, the extension wraps around the terminal welding end and extends to near its end, effectively resisting the impact of external force during installation and the vibration during use, ensuring the strength and reliability of the welding end. The connecting part is set at the housing mounting hole, and after subsequent glue filling, a connection is formed between the housing and the sheath. Then, a sealing gasket is set at one end of the housing, which covers the gap between the connecting part and the housing, reducing the light transmittance of the product and preventing glue from overflowing to the welding end during glue filling, thus avoiding glue contamination of the welding end and affecting the subsequent welding quality and connection.

[0006] The present invention can be further configured such that: a recess surrounding the mounting hole is provided at one end of the shell and a snap-fit ​​opening is provided on both sides of the recess; the two sides of the recess extend to the edge of the shell; the sealing gasket is installed in the recess and is provided with a snap-fit ​​head that can be snapped into the snap-fit ​​opening.

[0007] With further design, the surrounding recess provides guidance and positioning for the gasket, and ensures that the gasket can limit its height, thereby avoiding problems such as gasket displacement or detachment, and facilitating installation. The snap-fit ​​of the latch and the snap-fit ​​head enhances the positioning effect of the gasket, prevents accidental detachment, and ensures sealing stability, thereby ensuring the effect of preventing glue overflow and reducing light transmission through gaps.

[0008] The present invention can be further configured such that: the sheath includes a reinforcing portion disposed between adjacent extensions, the reinforcing portion extending to near the end of the extension.

[0009] With further design, the sheath is reinforced between adjacent extensions and extends to near the end of the extension, which can connect the extensions to improve the overall support strength, prevent deformation and breakage, and ensure the strength of the product.

[0010] The present invention can be further configured such that: the shell includes a shielding shell made of conductive material, the shielding shell is arranged around the plug end, the shielding shell is provided with a plurality of contact feet extending to one end of the shell, and the sealing gasket is provided with an opening for the contact feet to extend out.

[0011] By further designing the shielding shell, which is made of conductive material and surrounds the plug-in end, external electromagnetic interference can be effectively isolated, ensuring stable signal transmission at the plug-in end. The contact pins of the shielding shell can be extended to one end of the shell for easy grounding, ensuring the shielding effect and improving reliability. At the same time, the sealing gasket has an opening corresponding to the contact pin to avoid interfering with the function of the contact pin.

[0012] The present invention can be further configured such that: a guide portion is provided on the sheath, and the guide portion is located at the other end of the shell and is fitted to the inner wall of the shielding shell.

[0013] With further design, the sheath can be guided during assembly to prevent it from shifting or misaligning. The guide also provides lateral support to the sheath, preventing it from shaking due to vibration or external forces during use, thus ensuring product stability and indirectly extending the overall lifespan of the connector.

[0014] The present invention can be further configured such that: a limiting block is provided on the sheath, and the limiting block can abut against the inner wall of the slot for limiting.

[0015] By further configuring the limit block, it is made to abut against the inner wall of the slot, thus achieving the initial installation limit effect and facilitating subsequent installation.

[0016] The present invention can be further configured such that: a guide block is provided on the sheath, and the guide block can guide and cooperate with the inner wall of the slot.

[0017] With further modifications, the guide block allows the sheath to be quickly and accurately inserted into the housing during assembly, and it also has a mistake-proof function, further facilitating installation.

[0018] The present invention can be further configured such that: a connecting groove and an anti-misalignment post are provided at one end of the shell.

[0019] With further design, a connecting groove and an anti-misalignment post are provided at one end of the housing. The connecting groove is used to connect with external devices, and the anti-misalignment post ensures accuracy. Attached Figure Description
