Description

Technical Field

[0001] The utility model relates to the field of outdoor connectors, in particular to a small-volume waterproof connector suitable for outdoor use. Background Art

[0002] Connectors are also called connectors. Also known as connectors and sockets in China, they generally refer to electrical connectors. They are devices that connect two active components, transmitting current or signals.

[0003] Existing outdoor connectors (such as those used in drones, electric motorcycles, lawn mowers, and lamps) are typically waterproof. However, in certain outdoor environments, such as heavy rainfall, prolonged high humidity, or the presence of large amounts of dust and impurities, these external factors can potentially break through the connector's waterproof barrier and penetrate into its interior.

[0004] Rainwater penetration, condensation, and the accumulation of dust and impurities can damage the delicate structures and electronic components within connectors. This damage not only affects the connector's performance but can also cause short circuits and poor contact between terminals (for example, a short between the positive and negative terminals), significantly reducing the connector's lifespan and increasing equipment maintenance and replacement costs. Utility Model Content

[0005] The main purpose of the utility model is to provide a small-volume waterproof connector suitable for outdoor use, which is intended to prevent electrical interference between terminals and ensure the integrity and accuracy of the signal or current transmitted by each terminal.

[0006] To achieve the above objectives, the present invention provides a small-volume waterproof connector suitable for outdoor use, comprising:

[0007] A female connector, comprising a female rubber shell with a plurality of slots and a male terminal provided on the female rubber shell, wherein a partition is provided between adjacent slots, and a space is provided between the partition and the open end of the slot to form a sealed cavity;

[0008] The male connector includes a male plastic shell with multiple plug-in parts at the front end and a female terminal. The plug-in parts are provided with positioning grooves, and the female terminals are arranged in the positioning grooves. Isolation channels that cooperate with the partitions are provided between adjacent plug-in parts. The male plastic shell is located at the rear end of the isolation channel and has a recessed slot, and the slot is provided with a sealing ring;

[0009] The outer walls of the female rubber shell and the male rubber shell are provided with mutually cooperating locking devices, which are used to lock the female rubber shell and the male rubber shell together when the plug-in part and the slot are plugged into each other, and the outer peripheral wall of the sealing cavity and the sealing ring are elastically fitted.

[0010] By setting up mutually cooperating partitions and isolation channels between the female rubber shell and the male rubber shell, the following effects are achieved:

[0011] 1. Prevent electrical interference between terminals and ensure the integrity and accuracy of the signal or current transmitted by each terminal;

[0012] 2. Enhance electrical insulation. For terminals with different potentials, the isolation channel can provide reliable insulation and reduce the risk of leakage and short circuit;

[0013] 3. It can withstand harsher environments and extend the service life of the connector.

[0014] 4. This product features a miniaturized structure that shortens the length of the male and female terminals, resulting in a smaller housing. This can lead to an unstable connection between the male and female terminals, which may loosen or even fall off when subjected to external forces such as vibration and impact. The provision of isolation channels and partitions between the terminals effectively increases the strength of the connection between the male and female connectors (by reducing vibration forces in the width and height directions) and improves the stability of the overall connector structure.

[0015] 5. There is a gap between the partition and the opening of the slot, so when the male rubber shell and the female rubber shell are plugged in, the sealing ring and the sealing cavity can achieve the sealing of the plug-in part, thereby ensuring waterproofness.

[0038] like Figures 1 to 7 As shown, a small-volume waterproof connector suitable for outdoor use includes:

[0039] A female connector 1 includes a female housing 10 having a plurality of slots 12 and a male terminal 11 disposed on the female housing 10. A partition 13 is disposed between adjacent slots 12. A space is provided between the partition 13 and the open ends of the slots 12 to form a sealed cavity 31.

[0040] The male connector 2 includes a male plastic shell 20 with multiple plug-in parts 22 at the front end and a female terminal 21. The plug-in parts 22 are provided with positioning grooves, and the female terminal 21 is arranged in the positioning grooves. An isolation channel 23 that cooperates with the partition 13 is provided between adjacent plug-in parts 22. The male plastic shell 20 is provided with a recessed slot at the rear end of the isolation channel 23, and the slot is provided with a sealing ring 32;

[0041] The outer walls of the female rubber shell 10 and the outer walls of the male rubber shell 20 are provided with mutually cooperating locking devices, which are used to lock the female rubber shell 10 and the male rubber shell 20 with each other when the plug-in portion 22 and the slot 12 are plugged into each other, and the outer peripheral walls of the sealing cavity 31 and the sealing ring 32 are elastically fitted.

[0042] By providing a partition plate 13 and an isolation channel 23 that cooperate with each other between the female rubber shell 10 and the male rubber shell 20, the following effects are achieved:

[0043] 1. Prevent electrical interference between terminals and ensure the integrity and accuracy of the signal or current transmitted by each terminal;

[0044] 2. Enhanced electrical insulation: For terminals with different potentials, the isolation channel 23 can provide reliable insulation, reducing the risk of leakage and short circuit;

[0045] 3. It can withstand harsher environments and extend the service life of the connector.

[0046] 4. This product features a compact structure, shortening the length of the male and female terminals 11, 21, and reducing the size of the housing. This can lead to an unstable connection between the male and female terminals 21, which may loosen or even fall off when subjected to external forces such as vibration and impact. The isolation channel 23 and partition 13 provided between the terminals effectively increase the strength of the connection between the male and female connectors (by reducing vibration forces in the width and height directions) and enhance the stability of the overall connector structure.

[0047] 5. The partition 13 is spaced apart from the opening of the slot 12, so when the male rubber shell 20 and the female rubber shell 10 are plugged in, the sealing ring 32 and the sealing cavity 31 can achieve the sealing of the plug-in part 22, thereby ensuring waterproofness.

[0048] The male rubber shell 20 and the female rubber shell 10 are defined as the front end and the position away from the plug-in end is the back end. The length of the male rubber shell 20 is about half the length of the female rubber shell 10 (usually less than half), so the length is limited.

[0049] Specifically, the terminals can be arranged in multiple rows or columns, and can be arranged according to actual needs.

[0050] in Figure 4 There are two rows of terminals. Figure 5 A row of terminals.

[0051] Specifically, when the rear end of the male terminal 11 is a wire end terminal, the rear end of the female plastic shell 10 is provided with a female end accommodating cavity 4, and the female end accommodating cavity 4 is installed with a female end sealing plug 41. The female end sealing plug 41 is provided with a female end through-hole 42 for the cable to pass through, and the rear wall of the female end sealing plug 41 is provided with a female end back cover 43 that is clamped in the female end accommodating cavity 4. The arrangement of the female end sealing plug 41 and the female end back cover 43 ensures the sealing of the wire end, thereby ensuring the waterproofness of the cable.

[0052] Specifically, when the rear end of the male terminal 11 is a plate-end terminal 6, the rear end of the female rubber shell 10 is located between the two male terminals 11 and is provided with a positioning rib 61, and positioning columns 62 are provided on both sides of the rear wall of the female rubber shell 10;

[0053] The rear end of the male terminal 11 is provided with a hook 63 that cooperates with the rear end of the slot 12. The provision of the hook 63 allows the male terminal 11 to be stably installed in the slot 12. At the same time, the provision of the positioning rib 61 and the positioning column 62 allows the female plastic shell 10 to be stably installed on the PCB board, while achieving positioning, reducing the insertion and removal pressure of the male terminal 11, and improving the service life.

[0054] Specifically, the upper wall of the mother rubber shell 10 is provided with a rubber block 64, and the mother rubber shell is provided with an open slot 65 toward the rear end. In this design, an insert block can be set on the PCB board. When the mother rubber shell 10 is installed on the PCB board, the insert block extends into the open slot 65, and the positioning ribs 61 and positioning posts 62 are simultaneously locked in the holes of the PCB board, achieving multi-point positioning and ensuring stable installation of the mother rubber shell 10.

[0055] Specifically, when the rear end of the female terminal 21 is a wire end terminal, the rear end of the male plastic housing 20 is provided with a male terminal accommodating cavity 5, and the male terminal accommodating cavity 5 is installed with a male terminal sealing plug 51.
