Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a waterproof connector. Background Art

[0002] A connector is a device that connects two active components and is used to transmit current or signals. The main application areas for electrical connectors include transportation, communications, networking, IT, healthcare, and home appliances. The rapid technological advancements and market growth in these areas are strongly driving the development of connector technology. To date, connectors have developed into a series of specialized products with a comprehensive product range, rich specifications, diverse structural types, specialized niches, distinct industry characteristics, and a standardized standard system. Connectors consist of a male terminal assembly and a female terminal assembly that mates with the male terminal assembly. The male terminal assembly includes a male housing and multiple pins housed within the male housing. The female terminal assembly includes a female housing connected to the male housing and multiple female terminals housed within the housing that mate with the multiple pins. Existing connectors have poor waterproofing, allowing rainwater to easily enter the female terminal along the wiring harness, making these connectors unsuitable for use in harsh environments. Moreover, the pin of the male end has a large shaking space in the female terminal of the female end. Under repeated plugging and unplugging and high-frequency vibration environment, the male terminal and the female terminal are prone to poor contact, resulting in the defect of unreliable working performance of the connector. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a waterproof connector with compact structure, stable and reliable performance, reliable connection and good waterproof effect.

[0004] To achieve the above-mentioned purpose, the present invention adopts a waterproof connector, including a male end assembly and a female end assembly connected to the male end assembly, the male end assembly including a male rubber shell and a plurality of pins respectively arranged in the male rubber shell, the female end assembly including a plurality of female rubber shells connected to the male rubber shell, a plurality of female terminals respectively arranged in the plurality of female rubber shells and plugged with the plurality of pins, one end of the plurality of female terminals having a plurality of crimping parts crimped with the wiring harness, a rubber gasket covering the plurality of crimping parts is provided on the female rubber shell, a locking cover for pressing the rubber gasket is provided on the female rubber shell, a plurality of waterproof sealing holes for sealing with the wiring harness are respectively provided on the rubber gasket corresponding to the plurality of crimping parts, a plurality of through holes for the wiring harness to pass through are respectively provided on the locking cover corresponding to the plurality of waterproof sealing holes, and a plurality of anti-foolproof plug-in columns for matching with the circuit board are respectively provided at the plug-in parts of the male rubber shell corresponding to the plurality of pins.

[0005] The above structure has the following advantages: the rubber gasket provides waterproofing, enhancing the seal between the locking cover and the female housing, thereby preventing rainwater from entering the female housing along the wiring harness, and achieving enhanced waterproofing. Furthermore, the foolproof plug post ensures a more reliable connection between the pins and the circuit board. Furthermore, the male housing can be plugged into multiple female housings, allowing a single male housing to connect to multiple female housings. This modularized circuit design results in a more compact structure and lowers costs. Consequently, this connector offers the advantages of a compact structure, stable and reliable performance, reliable connection, and excellent waterproofing.

[0006] Specifically, the locking cover is provided with a plurality of gussets on either side, and the outer wall of the mother rubber shell is provided with a plurality of clips that cooperate with the gussets. The clips engage with the gussets in the holes of the gussets, thereby forming a snap-fit connection between the locking cover and the mother rubber shell. The snap-fit connection between the locking cover and the mother rubber shell facilitates assembly of the locking cover and the mother rubber shell, and ensures a more compact connection between the locking cover and the mother rubber shell.

[0007] In particular, two stop plates are provided at each end of the locking cover. These two stop plates are respectively attached to the outer wall of the mother rubber shell, and form a stoppering cooperation between the two stop plates and the mother rubber shell. The locking cover abuts against the outer wall of the mother rubber shell via the two stop plates, thereby ensuring a more compact and secure connection between the locking cover and the mother rubber shell.

[0008] In particular, the male housing is provided with a glue filling groove at the insertion portion corresponding to the plurality of pins, and the glue filling groove is filled with sealant. The sealant can provide a waterproof effect, preventing rainwater from entering the male housing along the pins, thereby improving the waterproof performance of the connector.

[0009] Specifically, the female terminals are provided with a plurality of plug-in frames at one end, which mate with the plurality of pins. The plurality of pins are provided with a plurality of pin portions inserted into the plug-in frames at one end. The plug-in frames are provided with a plurality of contact bumps that abut against both sides of the plurality of pin portions. The plug-in frames of the female terminals are pressed against the pins via the contact bumps, thereby ensuring a more reliable connection between the female terminals and the pins.
