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 devices 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 that connects to the male housing and multiple female terminals housed within the female housing and that mate with the multiple pins. Existing connectors have loose connections between the male and female housings, which can easily wobble after connection, resulting in an unreliable connection between the male and female assemblies. Furthermore, these connectors have poor waterproofing, allowing rainwater to easily enter the connector, making them unsuitable for use in harsh environments. 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 utility model 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 female rubber shell connected to the male rubber shell, a plurality of female terminals respectively arranged in the female rubber shell and plugged with the plurality of pins, one end of the female rubber shell is provided with a sealing groove sleeved on the male rubber shell, a sealing ring is provided in the sealing groove that abuts against the male rubber shell and forms a sealing fit between the male rubber shell and the female rubber shell, and a limiting groove is provided on the sealing groove, a limiting block is provided on the male rubber shell that matches the limiting groove, the limiting block is engaged in the limiting groove, and forms a limiting fit between the limiting block and the female rubber shell, the female rubber shell is provided with an elastic hook that matches the limiting block, the elastic hook is buckled on the limiting block, and forms a snap-fit fit between the limiting block and the elastic hook.

[0005] The beneficial effects of the above structure are as follows: a sealing ring is provided between the female rubber shell and the male rubber shell, which can play a waterproof role, thereby enhancing the waterproof effect of the connector, and the sealing groove of the female rubber shell is sleeved on the male rubber shell, and the female rubber shell is engaged with the limit block of the male rubber shell through the limit slot, thereby preventing the male and female rubber shells from swinging after being plugged in. The connection between the male end assembly and the female end assembly is more compact and firm, and the limit block of the male rubber shell is engaged with the elastic hook of the female rubber shell, thereby facilitating the assembly of the male and female rubber shells and ensuring a more reliable connection between the male and female end assemblies. As a result, the connector has the advantages of compact structure, stable and reliable performance, reliable connection, and good waterproof effect.

[0006] In particular, one end of the elastic hook has a hook-shaped body that cooperates with the limit block, and the other end of the elastic hook has an unlocking pressing portion. The limit block is provided with a guide bevel and a locking bevel that cooperate with the hook-shaped body, respectively. The hook-shaped body slides along the guide bevel to the locking bevel, forming a limited fit between the hook-shaped body and the locking bevel. The elastic hook passes through the guide bevel and the locking bevel of the limit block. The guide bevel can play a guiding role, thereby facilitating the insertion of the male and female rubber shells, and the locking bevel can play a locking role, thereby ensuring a more compact connection between the male and female rubber shells.

[0007] In particular, the multiple female terminals have multiple crimping portions at one end for crimping with the wiring harness, the female connector housing is provided with a rubber gasket covering the multiple crimping portions, and the female connector housing is provided with a locking cover for compressing the rubber gasket. The rubber gasket is provided with multiple waterproof sealing holes corresponding to the multiple crimping portions, respectively, for sealing with the wiring harness, and the locking cover is provided with multiple through-holes for allowing the wiring harness to pass through, respectively, corresponding to the multiple waterproof sealing holes. The rubber gasket provides a waterproof effect, preventing rainwater from flowing along the wiring harness into the female connector housing, thereby improving the waterproof effect of the connector.

[0008] 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.

[0009] 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.

[0010] 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.
