DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0039] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] In the description of this application, "first feature" or "second feature" may include one or more of the features. In the description of this application, "plurality" means two or more.

[0041] In the description of the present application, a first feature being “on” or “under” a second feature may include the first and second features being in direct contact with each other, or the first and second features being in contact with each other not directly but via another feature therebetween.

[0042] In the description of this application, a first feature “on”, “above” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0043] The connector 300 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0044] As shown in Figures 1-5, the connector 300 of the present application includes a first housing 12, a first sealing ring 11, a second housing 10, and at least one electrical connection terminal. The first housing 12 is provided with at least one mating groove 121. The mating groove 121 extends through the inner wall 123 and the outer wall 124 of the first housing 12. The mating groove 121 has a notch 1214 extending along the first direction D1. More specifically, the mating groove 121 forms a first opening 1211 on the inner wall 123, a second opening 1212 on the outer wall 124, and a notch opposite the groove bottom 1213. The first sealing ring 11 includes a main body 115 and a mating portion 116. The main body 115 is configured to be sleeved onto the first housing 12. The mating portion 116 is disposed on the inner side of the main body 115. The mating portion 116 includes a stop 112 and a first connecting portion 111 connected between the stop 112 and the main body 115. The stop 112 is configured to be located on the inner side of the first housing 12. The first connection portion 111 is configured to at least partially fit within the mating groove 121, or in other words, to be at least partially located within the mating groove 121. When the first connection portion 111 is at least partially located within the mating groove 121, the stop 112 is located inside the first housing 12, and the width of the stop 112 is greater than the width of the mating groove 121, thereby clamping the first housing 12 between the main body 115 and the stop 112, thereby stably connecting the first connection portion 111 to the mating groove 121. The second housing 10 mates with the first housing 12 along the first direction D1 to prevent the first connection portion 111 from escaping from the mating groove 121 through the notch 1214. The size of the stop 112 is greater than the size of the first opening 1211, preventing the stop 112 from passing through the first opening 1211. This restricts the movement of the main body 116 of the first sealing ring 11 away from the stop 112, preventing the first sealing ring 11 from loosening or even falling off. The electrical connection terminal 20 is disposed through the first housing 12. The first shell 12 may be made of an aluminum alloy structure, and its surface may be processed by sandblasting and passivation.

[0045] Optionally, the mating portion 116 is configured as a T-shaped structure. It should be understood that configuring the mating portion as a T-shaped structure is only one embodiment of the present application. In other embodiments, the mating portion 116 can also be configured as a coaxial cylindrical combination, wherein the axial radius of the stop 112 must be greater than the axial radius of the first connecting portion 111. The present application does not impose any restrictions on the specific structure of the mating portion, as long as the first connecting portion 111 can be mated with the mating groove 121 and the mating portion 116 is not easily separated from the first housing 12 along a direction perpendicular to the first direction D1.

[0046] Optionally, the first sealing ring 11 is sleeved on the outer wall surface 124 of the head of the first shell 12, wherein the first connecting portion 111 of the first sealing ring 11 is interference-fitted with the mating groove 121. It should be understood that the interference fit between the first connecting portion 111 and the mating portion is only one embodiment of the present application. This type of fit can make the mating portion 116 and the mating groove 121 tightly connected, making it less likely that the first sealing ring 11 will fall off from the first shell 12. In other embodiments, a clearance fit between the first connecting portion 111 and the mating groove 121 is also feasible. As long as the stop 112 can be supported on the first shell 12 and produce an abutment effect, the mating portion 116 is not easily separated from the first shell 12 in the direction perpendicular to the first direction D1, which can also improve the stability of the connector 300.

[0047] Optionally, the mating portion 116 is provided on one side of the first sealing ring 11 in the first direction D1. It should be understood that the provision of the mating portion 116 on one side of the first sealing ring 11 in the first direction D1 is only one embodiment of the present application. In actual use scenarios, as the connector 300 is continuously plugged and unplugged, the first sealing ring 11 will detach from the side of the first shell 12 in the first direction D1. Therefore, the provision of the mating portion 116 on one side of the first sealing ring 11 in the first direction D1 is a preferred embodiment. It should be understood that the provision of the mating portion 116 on the opposite side in the first direction D1, or the provision of the mating portion 116 on both sides of the first sealing ring 11 in the first direction D1, can be an embodiment of the present application, as long as the mating portion 116 can achieve the mating effect with the mating groove 121 on the first shell 12.

[0048] Optionally, the mating grooves 121 and the mating portions 116 are provided in a corresponding manner, and both may be provided in a plurality. Since the first sealing ring 11 is assembled with the first housing 12 via the mating portions 116, the mating grooves 121 and the mating portions 116 need to be identical in number and positioned in a one-to-one correspondence to avoid situations where the first sealing ring 11 cannot be assembled into the first housing 12.

[0049] Optionally, the second shell 10 is provided with a clamping arm 105, and the inner side of the first shell 12 is provided with a hanging platform 125, and the clamping arm cooperates with the hanging platform 125 to prevent the second shell 10 and the first shell 12 from moving relative to each other. The second shell 10 is installed in the inner cavity of the first shell 12. The clamping arm 105 includes a first clamping arm 101 and a second clamping arm 102. The first clamping arm 101 and the second clamping arm 102 on the second shell 10 cooperate with the hanging platform 125 on the first shell 12 to prevent the second shell 10 from separating from the first shell 12. At the same time, the second shell 10 and the first shell 12 cooperate to prevent the first sealing ring 11 from shaking along the first direction D1. At the same time, the first shell 12 and the second shell 10 can also be unlocked and the components replaced by a disassembly tool. It should be understood that the cooperation setting of the clamping arm 105 and the hanging platform 125 is only one embodiment of the present application. In other embodiments, other cooperation methods can also be adopted, such as fixing by adhesion, as long as the cooperation and fixation can be achieved.

[0050] Optionally, a flange 113 is provided on the outer surface of the first sealing ring 11. The flange 113 is triangular in shape. The edge of the flange 113 is set to a bevel 114. The second shell 10 is provided with a positioning arm 104, and the positioning arm 104 squeezes the bevel 114 to prevent the first sealing ring 11 from detaching. Among them, the number of flanges 113 is set to 3. By squeezing the bevel 114 on the first sealing ring 11 by the positioning arm 104 of the second shell 10, the first sealing ring 11 can be further prevented from detaching from the first shell 12. It should be understood that setting the number of flanges 113 to 3 is only a preferred solution, and this application does not limit the specific number of flanges 113.

[0051] Optionally, the electrical connection terminal 20 includes a copper bus terminal 22 and a cable 21 that can be electrically connected to the copper bus terminal 22.

The first connecting end 144 is the second connecting portion. The cable end 211 is ultrasonically connected to the first connecting end 144. Ultrasonic welding of the first copper busbar terminal 14 and the cable 21 ensures high weld strength and excellent conductivity. After welding, the first copper busbar terminal 14 and the cable 21 are assembled from the rear of the first housing 12 into the inner cavity of the second housing 10. The inclined platform 103 on the second housing 10 cooperates with the first positioning bevel 143 on the first copper busbar terminal 14 to prevent the first copper busbar terminal 14 from detaching. The second arm 102 of the second housing 10 cooperates with the first limiting groove 142 on the first copper busbar terminal 14 to prevent the first copper busbar terminal 14 from detaching. The inner cavity of the second housing 10 cooperates with the outer shape of the first copper busbar terminal 14 to prevent the first copper busbar terminal 14 from shaking. Thus, the first copper bus terminal 14 is reliably fixed.

[0054] The second copper busbar terminal 15 includes a second connection area 151, a second limiting groove 152, a second positioning bevel 153, and a second connecting end 154. The second connecting end 154 is the second connecting portion, and the cable end 211 is ultrasonically connected to the second connecting end 154. Ultrasonic welding of the second copper busbar terminal 15 and the cable 21 ensures high weld strength and excellent conductivity. After welding, the second copper busbar terminal 15 and the cable 21 are assembled into the inner cavity of the second housing 10 from the rear of the first housing 12. The inclined platform 103 on the second housing 10 cooperates with the second positioning bevel 153 on the second copper busbar terminal 15 to prevent the copper busbar terminal 15 from detaching. The second arm 102 on the second housing 10 cooperates with the second limiting groove 152 on the second copper busbar terminal 15 to prevent the second copper busbar terminal 15 from detaching. The inner cavity of the second housing 10 cooperates with the outer shape of the second copper busbar terminal 115 to prevent the second copper busbar terminal 15 from shaking. Thus, the second copper bus terminal 15 is reliably fixed.

[0055] Optionally, the connector 300 further includes a tail cover 19, which is arranged on the side of the first shell 12 opposite to the first sealing ring 11 in the first direction D1. The first shell 12 is also provided with a boss 126 and a limit platform 122. The tail cover 19 is provided with a card slot 192 and a limit arm 191. The boss 126 cooperates with the card slot 192, and the limit platform 122 cooperates with the limit arm 191 to fix the electrical connection terminal 20. It should be understood that the cooperation between the boss 126 and the card slot 192, and the limit platform 122 and the limit arm 191 are all embodiments of the present application.
