[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1-4As shown, this embodiment provides a waterproof connector assembly, particularly suitable for electrical and signal connections between circuit boards. The waterproof connector assembly includes a male connector 100 and a female connector 200. The male connector 100 is mounted on an inner panel, and the female connector 200 is mounted in a clearance groove on an outer panel. The female connector 200 has an insertion slot 202, into which the male connector 100 is inserted and electrically connected to the female connector 200. It should be noted that both the inner and outer panels are circuit boards. In this embodiment, the inner panel is specifically a driver board for an LED product, while the outer panel is specifically a lamp board for an LED product. Both the inner and outer panels are equipped with multiple electrical components to achieve their functions.

[0037] Furthermore, such as Figures 1-4 As shown, the male connector 100 is fitted with a first sealing ring 110 on its outer periphery, and the female connector 200 is fitted with a second sealing ring 210 on its outer periphery. The first sealing ring 110 is used to seal the gap between the outer periphery of the male connector 100 and the inner wall of the insertion groove 202, and the second sealing ring 210 is used to seal the gap between the outer periphery of the female connector 200 and the clearance groove.

[0038] Specifically, in the waterproof connector assembly provided in this embodiment, the male connector 100 and the female connector 200 are respectively mounted on the inner and outer plates. When the male connector 100 is inserted into the insertion slot 202 on the female connector 200, the inner and outer plates are electrically connected through the waterproof connector assembly. On one hand, the male connector 100 and the insertion slot 202 are sealed by a first sealing ring 110, achieving inner-layer waterproofing; on the other hand, the clearance slot of the female connector 200 and the outer plate are sealed by a second sealing ring 210, achieving outer-layer waterproofing. In summary, the waterproof connector assembly provided in this embodiment achieves double-layer waterproofing by setting the first sealing ring 110 and the second sealing ring 210, resulting in stronger waterproofing performance and higher electrical connection stability.

[0039] For example, such as Figure 3 As shown, along the width direction of the first sealing ring 110, the first sealing ring 110 is provided with at least two spaced first protrusions 111. The first protrusions 111 extend in the same direction as the first sealing ring 110 and press against the inner wall of the insertion groove 202, thereby providing multiple seals between the male connector 100 and the insertion groove 202, further improving the sealing reliability.

[0040] For example, such as Figure 3As shown, along the width direction of the second sealing ring 210, the second sealing ring 210 is provided with at least two spaced second protrusions 211. The second protrusions 211 extend in the same direction as the second sealing ring 210 and press against the inner wall of the relief groove, thereby providing multiple seals between the female connector 200 and the relief groove, further improving the sealing reliability.

[0041] For example, such as Figure 3 and Figure 4 As shown, the male connector 100 is provided with a first mounting groove 101. The first mounting groove 101 is configured as an annular structure extending around the outer periphery of the male connector 100. The first sealing ring 110 is fitted into the first mounting groove 101. The first mounting groove 101 provides a limiting and auxiliary installation function for the first sealing ring 110.

[0042] For example, such as Figure 3 and Figure 4 As shown, the female connector 200 has a second mounting groove 201 on its outer periphery. The second mounting groove 201 is configured as an annular structure extending around the outer periphery of the female connector 200. The second sealing ring 210 is fitted into the second mounting groove 201. The second mounting groove 201 provides a limiting and auxiliary installation function for the second sealing ring 210.

[0043] For example, such as Figures 1-4 As shown, the male connector 100 includes a first housing 120 and a plurality of first pins 130. The plurality of first pins 130 are inserted into the first housing 120 and are signal connected to a first board. A first mounting groove 101 is formed on the periphery of the first housing 120.

[0044] For example, such as Figures 1-4 As shown, the female connector 200 includes a second housing 220 and a plurality of second pins 230. The plurality of second pins 230 are inserted into the second housing 220 and are signal connected to the second board. The second mounting groove 201 is formed on the periphery of the second housing 220. When the male connector 100 is inserted into the insertion groove 202, the plurality of first pins 130 and the plurality of second pins 230 are electrically connected in a one-to-one correspondence, thereby realizing the signal connection between the first board and the second board.

[0045] For example, such as Figure 2 As shown, the first housing 120 is provided with a plurality of connection slots 1201, which are arranged in a matrix. A plurality of first pins 130 are respectively disposed in the connection slots 1201. One end of the second pin 230 extends along the depth direction of the insertion slot 202. When the male connector 100 is inserted into the insertion slot 202, the plurality of second pins 230 are respectively inserted into the connection slots 1201, and the second pins 230 contact the first pins 130 in the connection slots 1201 to conduct electricity.

[0046] For example, the first pin 130 is configured as a spring-loaded structure, which can elastically deform along the width direction of the connecting slot 1201 to fit tightly against the second pin 230, thereby improving the stability of the electrical connection.

[0047] For example, such as Figures 1-4 As shown, the waterproof connector assembly also includes a power male pin 20 and a power female pin 10. One of the male connector 100 and the female connector 200 is provided with a power male pin 20, and the other is provided with a power female pin 10. When the male connector 100 is inserted into the insertion slot 202, the power male pin 20 is inserted into the power female pin 10, thereby enabling electrical conduction between the first board and the second board through the waterproof connector assembly. The same connector structure can simultaneously realize the functions of signal connection and power supply connection.

[0048] In this embodiment, as Figures 1-4 As shown, the male connector 100 is provided with a power female pin 10, and the female connector 200 is provided with a power male pin 20. Specifically, the first housing 120 includes a first signal connection area 121 and two first power supply connection areas 122. Multiple first pins 130 are located in the first signal connection area 121, and the two first power supply connection areas 122 are respectively located at both ends of the first signal connection area 121. A power female pin 10 is inserted into the first power supply connection area 122. The second housing 220 includes a second signal connection area 221 and two second power supply connection areas 222. Multiple second pins 230 are located in the second signal connection area 221, and the two second power supply connection areas 222 are respectively located at both ends of the second signal connection area 221. A power male pin 20 is inserted into the second power supply connection area 222, with one end of the power male pin 20 extending along the depth direction of the insertion groove 202. The power male pin 20 and power female pin 10 on both sides serve as the positive and negative terminals for power supply connection, respectively.

[0049] For example, such as Figures 1-4 As shown, each first power supply connection area 122 has at least two power male pins 20 arranged side by side, and the at least two power male pins 20 are connected in parallel. Correspondingly, each second power supply connection area 222 has at least two power female pins 10 arranged side by side, and the at least two power female pins 10 are connected in parallel, thereby increasing the upper limit of the load so as to realize a high current power supply connection.

[0050] For example, both the power male pin 20 and the power female pin 10 adopt the high-current male and female pin structure in the prior art. The power male pin 20 is set as a columnar structure, while the power female pin 10 is set as a blind hole structure with a fastening spring or elastic spring structure inside to clamp the power male pin 20, thereby improving the connection stability between the power male pin 20 and the power female pin 10.

[0051] For example, the power male pin 20 and the power female pin 10 are made of brass.

[0052] For example, the first sealing ring 110 is made of silicone, which is durable and corrosion-resistant, thus ensuring its service life.

[0053] For example, the second sealing ring 210 is made of silicone, which is durable and corrosion-resistant, thus ensuring its service life.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
