It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the three-dimensional structure of a lamp in an embodiment of the present application and its partially enlarged structure, Figure 2 yes Figure 1 A partial schematic diagram of the cross-sectional structure of the lamp in FIG. Figure 3 yes Figure 2A schematic diagram of the partial enlarged structure at the circle A in FIG. The present application provides a lamp 100, which includes at least two lamp modules 10 and a snap-in 20, wherein the snap-in 20 is disposed between two adjacent lamp modules 10, and the opposite ends of the snap-in 20 are respectively snap-connected with the lamp modules 10 on the corresponding sides, so as to combine and connect at least two lamp modules 10. By disposing the snap-in 20 between two adjacent lamp modules 10, and snap-connecting the opposite ends of the snap-in 20 with the two lamp modules 10, not only can at least two lamp modules 10 be combined to improve the lighting effect, but also the snap-in 20 has a simple structure, which facilitates the installation and removal of at least two lamp modules 10, so as to improve the user experience.

[0033] Optionally, in this embodiment, if Figure 1 and Figure 2 As shown, there are two lamp modules 10, and the clamping member 20 is disposed between the ends of the two lamp modules 10 to clamp and connect the ends of the two lamp modules 10. In another embodiment, the number of lamp modules 10 can also be set to three, four or five, etc., which is not specifically limited in the embodiment of the present application.

[0034] In one embodiment, if Figure 4 As shown, Figure 4 yes Figure 1 Each lamp module 10 includes a lamp body 12, a light source 14 and an end cap 16. The lamp body 12 is provided with a light source installation cavity 122. The light source 14 is arranged in the light source installation cavity 122. The end caps 16 are arranged at opposite ends of the lamp body 12 to cover the light source installation cavity 122.

[0035] Specifically, in this embodiment, the lamp body 12 includes a frame 121 and a light-transmitting cover 123 connected to one side of the frame 121. The frame 121 and the light-transmitting cover 123 surround a light source installation cavity 122. The light source 14 is fixed on the frame 121. The light emitted by the light source 14 passes through the light-transmitting cover 123 and then is emitted.

[0036] Among them, in this embodiment, the frame 121 can be made of a profile. A profile refers to a solid straight bar of metal that has been formed by plastic processing and has a certain cross-sectional shape and size. A profile is an object with a certain geometric shape made of iron or steel and a material with a certain strength and toughness through rolling, extrusion, casting and other processes. This embodiment uses a profile to make the frame 121 of the lamp body 12. On the one hand, it can simplify the manufacturing process of the lamp body 12 and improve production efficiency. On the other hand, it can also facilitate the production of lamp modules 10 of different lengths to meet the usage requirements of different users.

[0037] Optionally, in this embodiment, the light source 14 may include a plurality of LED lamp beads. In other optional embodiments, the light source 14 may also be a sodium lamp, an energy-saving lamp, etc., which is not specifically limited in the embodiment of the present application.

[0038] Furthermore, if Figure 3 and Figure 5 As shown, Figure 5 yes Figure 1 The end cap 16 includes a middle plate 162 and a sleeve 164 and a mounting portion 166 disposed on opposite sides of the middle plate 162. The middle plate 162 abuts against the end surface of the lamp body 12. The sleeve 164 is sleeved on the outer wall of the lamp body 12 to seal the light source mounting cavity 122. The mounting portion 166 is provided with a snap hole 168. The snap connector 20 is snap-fitted with the snap holes 168 on two adjacent lamp modules 10, that is, the opposite ends of the snap connector 20 are snap-fitted with the end caps 16 on the corresponding sides, so as to combine and connect at least two lamp modules 10.

[0039] Specifically, in this embodiment, the cross-sectional shape of the sleeve 164 is adapted to the cross-sectional shape of the lamp body 12, and the inner wall size of the sleeve 164 is equal to the outer wall size of the lamp body 12. The sleeve 164 is sleeved on the periphery of the lamp body 12 to fix the frame 121 and the light-transmitting cover 123. In this way, compared with using a connection structure such as screws to fix the frame 121 and the light-transmitting cover 123, the sleeve connection method can avoid drilling holes on the lamp body 12 on the one hand, so as to improve the sealing performance of the lamp body 12; on the other hand, it can also improve the installation efficiency of the lamp body 12 and reduce the production cost. By abutting the middle plate 162 against the end face of the lamp body 12, the end cover 16 can be positioned to prevent the end cover 16 from sliding relative to the lamp body 12 in the axial direction of the lamp body 12.

[0040] In another embodiment, a tubular lamp body 12 with an integrated structure can also be used as needed. In this case, the cross-sectional shape of the sleeve 164 can be set to match the cross-sectional shape of the lamp body 12, and the outer wall size of the sleeve 164 is equal to the inner wall size of the lamp body 12. The lamp body 12 is sleeved on the outer periphery of the sleeve 164 to achieve a sealed connection between the lamp body 12 and the end cover 16.

[0041] In this embodiment, the mounting portion 166 is disposed on the side of the middle plate 162 away from the lamp body 12 , and the snap hole 168 is provided on the mounting portion 166 for mating with the snap-in component 20 , thereby connecting two adjacent lamp modules 10 to form an integrated structure.

[0042] Specifically, Figure 3 and Figure 5As shown, the mounting portion 166 has an end face facing away from the middle plate 162 and a side face adjacent to the end face, and the buckle hole 168 has a first opening 167 located on the end face and a second opening 169 located on the side face, wherein the end face, the side face and the side wall of the buckle hole 168 of the mounting portion 166 can be surrounded to form a buckle 161 for being engaged with the clamping member 20. By forming the buckle hole 168 in the mounting portion 166 and then forming the buckle 161 at the junction of the end face and the side face, the volume of the mounting portion 166 can be reduced on the one hand, and the strength of the buckle 161 can be improved on the other hand, so that the connection between the mounting portion 166 and the clamping member 20 is more stable.

[0043] Furthermore, if Figure 3 and Figure 5 As shown, there are two snap holes 168 arranged on each mounting portion 166, and the two snap holes 168 are spaced apart at opposite ends of the mounting portion 166 along a direction perpendicular to the connection direction of at least two lamp modules 10. There are two snap connectors 20 located between two adjacent lamp modules 10, and each snap connector 20 is snapped into a corresponding snap hole 168.

[0044] Specifically, in this embodiment, Figure 3 As shown, the connection direction of at least two lamp modules 10 is the X direction, and two snap holes 168 are spaced apart on opposite sides of the mounting portion 166 along the Y direction perpendicular to the X direction to form snap connections on opposite sides of the mounting portion 166, so that the lamp module 10 is evenly stressed and the connection strength and stability of the two lamp modules 10 can be improved.

[0045] In this embodiment, the Y direction is Figure 3 In another embodiment, the Y direction can also be Figure 3 The direction perpendicular to the paper surface shown in is not specifically limited in the embodiments of the present application.

[0046] Furthermore, if Figure 3 and Figure 5 As shown, a connector 165 is provided on one side of the mounting portion 166 away from the middle plate 162 . The connector 165 is located between two snap holes 168 . Each connector 165 is electrically connected to the light source 14 , and the connectors 165 on two adjacent lamp modules 10 are electrically connected.

[0047] Specifically, in this embodiment, the connectors 165 between two adjacent lamp modules 10 are electrically connected to each other to connect at least two lamp modules 10 in series, so that at least two lamp modules 10 can be powered simultaneously by one power supply, so as to simplify the structure of the lamp 100, reduce the production cost of the lamp 100, and facilitate installation and use. By arranging the connector 165 between the two buckle holes 168, the opposite sides of the connector 165 can be evenly stressed, avoiding skewing and causing the electrical connection failure of the connector 165, so as to improve the working stability.

[0048] In one embodiment, one of the two connectors 165 on two adjacent lamp modules 10 can be set as a male connector, and the other can be set as a female connector, and the two connectors 165 can be electrically connected by plugging and matching the male connector and the female connector. By providing a male connector and a female connector that plug and match each other, the electrical connection efficiency of the connector 165 can be improved, the electrical connection stability of the connector 165 can be improved, and the electrical connection structure of the lamp module 10 can be simplified.

[0049] In another embodiment, the two connectors 165 on two adjacent lamp modules 10 may be electrically connected via a wire, or electrically connected via a spring, or the two connectors 165 may be directly brought into contact and electrically connected, which is not specifically limited in the embodiment of the present application.

[0050] In this embodiment, if Figure 3 As shown, the lamp 100 further includes an electrical connector 30 , and opposite ends of the electrical connector 30 are electrically connected to the connectors 165 on the lamp modules 10 on the corresponding sides, so as to electrically connect two adjacent lamp modules 10 .

[0051] Specifically, in this embodiment, terminals for cooperating with the connecting heads 165 are provided at the opposite ends of the electrical connector 30. By electrically connecting the terminals at the opposite ends of the electrical connector 30 to the connecting heads 165 on the corresponding sides respectively, the connection stability of the two connecting heads 165 can be improved.

[0052] In one embodiment, one of the connector 165 and the electrical connector 30 that cooperate with each other may be provided with a pin 163, and the other of the connector 165 and the electrical connector 30 may be provided with a socket 32, and the pin 163 is plugged and electrically connected with the socket 32. By plugging and electrically connecting the electrical connector 30 and the corresponding connector 165, the electrical connection stability can be improved.

[0053] Furthermore, in this embodiment, the two connectors 165 on the lamp module 10 may have the same structure, and the terminals at opposite ends of the electrical connector 30 may have the same structure, so that the structure of the end caps 16 on each lamp module 10 is completely the same. In this way, on the one hand, the electrical connector 30 can be installed in a non-directional manner to improve the installation efficiency; on the other hand, it can also facilitate the mass production of the end caps 16 to reduce the production cost.

[0054] Furthermore, if Figure 3 , Figure 6 and Figure 7 As shown, Figure 6 yes Figure 3 A schematic diagram of the three-dimensional structure of the card connector in FIG. Figure 7 yes Figure 6 The planar structural diagram of the clamping member in FIG. The clamping member 20 includes a carrier plate 21 and undercuts 23 arranged at both ends of the carrier plate 21. The two undercuts 23 are arranged at intervals on the same surface of the carrier plate 21 to form a clamping groove 22 between the two undercuts 23. The undercuts 23 are respectively used to be clamped and connected with the clamps 161 on the lamp modules 10 on the corresponding sides. The clamps 161 on the two lamp modules 10 are embedded in the clamping grooves 22.

[0055] Specifically, in this embodiment, Figure 3 and Figure 6 As shown, two undercuts 23 are arranged on the side of the carrier plate 21 away from the connector 165, and each undercut 23 is inserted into the snap hole 168 from the first opening 167 on the corresponding side. The undercut 23 is elastically deformed under the squeezing action of the snap hole 168, and returns to its original shape under the action of elastic force when it moves to the position of the second opening 169, and is snapped on the side wall of the second opening 169. In this embodiment, by arranging undercuts 23 at opposite ends of the carrier plate 21, two lamp modules 10 can be connected to the same carrier plate 21 through the snap-fitting of the two undercuts 23 and the corresponding snaps 161, that is, the detachable connection of the two lamp modules 10 is realized through a snap connector 20. In this way, the snap connector 20 is not only novel in structure, but also convenient to install, which can greatly simplify the connection structure of the two lamp modules 10, and can also improve the production and assembly efficiency.

[0056] In this embodiment, the undercuts 23 are symmetrically disposed at two opposite ends of the carrier plate 21 , so that the opposite ends of the clamping member 20 are subjected to uniform force.

[0057] Furthermore, the distance between the side walls of the second openings 169 on the two mounting portions 166 engaged with the engaging member 20 may be set equal to the length of the engaging groove 22 along the connecting direction of at least two lamp modules 10 .

[0058] Specifically, Figure 3 and Figure 7 As shown, the distance between the side walls of the second openings 169 on the two mounting portions 166 is L, and the length of the snap-in groove 22 along the connection direction X of the lamp module 10 is S. By setting L=S, the end faces of the mounting portions 166 of the two lamp modules 10 can be abutted against each other, which can not only avoid relative shaking of the lamp modules 10 and improve the connection stability, but also reduce the possibility of external impurities or moisture entering between the two lamp modules 10, thereby reducing the probability of failure of the lamp 100.

[0059] Furthermore, if Figure 3 , Figure 6 and Figure 7 As shown, the clamping member 20 also includes a support plate 24 and a connecting plate 25. The support plate 24 is spaced apart on the side of the supporting plate 21 away from the undercut 23 to form a deformation space 26 between the support plate 24 and the supporting plate 21. The connecting plate 25 is disposed between the support plate 24 and the supporting plate 21, and the opposite ends of the connecting plate 25 are respectively connected to the support plate 24 and the supporting plate 21.

[0060] Specifically, in this embodiment, the connecting plate 25 is disposed between the support plate 24 and the carrier plate 21 to form a gap between the support plate 24 and the carrier plate 21. When one end of the clip 20 is connected with the clip hole 168, the one end of the clip 20 is first inserted into the clip hole 168 from the first opening 167, and the abutment of the side wall of the clip hole 168 on the undercut 23 can drive the end of the carrier plate 21 provided with the undercut 23 to bend toward the direction close to the support plate 24, so that the undercut 23 can enter the clip hole 168. When the clip 20 moves to the position of the second opening 169, the abutment force of the clip hole 168 on the undercut 23 disappears, and the carrier plate 21 returns to its original state under the action of the elastic force, abuts on the side wall of the clip hole 168, and the undercut 23 is engaged with the side wall of the second opening 169, so that the clip 20 is fixed to the mounting portion 166. By forming a deformation space 26 on the side of the bearing plate 21 away from the undercut 23 , the undercut 23 can be easily inserted into the buckle hole 168 , thereby reducing the difficulty of installation.

[0061] Among them, Figure 6 and Figure 7As shown, in this embodiment, the support plate 24 and the carrier plate 21 are arranged in parallel and spaced apart, the connecting plate 25 is connected to the middle of the support plate 24 and the carrier plate 21, and the connecting plate 25 is perpendicular to the support plate 24 and the carrier plate 21 to form a substantially H-shaped clamping member 20. By arranging the support plate 24 and the carrier plate 21 in parallel and spaced apart, the sizes of the deformation spaces 26 at the opposite ends of the carrier plate 21 can be made substantially equal, so as to shorten the height of the clamping member 20 in the direction perpendicular to the connection direction of at least two lamp modules 10, thereby reducing the volume of the clamping member 20. By vertically connecting the opposite ends of the connecting plate 25 to the middle of the support plate 24 and the carrier plate 21, on the one hand, the load on the opposite ends of the carrier plate 21 can be uniformly applied, and on the other hand, the interference of the connecting plate 25 with the deformation of the carrier plate 21 can be avoided.

[0062] like Figure 8 As shown, Figure 8 : is a schematic diagram of the planar structure of the clamping member in another embodiment of the present application. In another embodiment, the support plate 24 and the carrier plate 21 are arranged in parallel and spaced apart, the opposite ends of the connecting plate 25 are connected to the support plate 24 and the carrier plate 21, and the angle between the connecting plate 25 and the carrier plate 21 and the support plate 24 is not a right angle, that is, the connecting plate 25 is arranged obliquely relative to the carrier plate 21 and the support plate 24. In this way, the deformation ability of the clamping member 20 in the direction perpendicular to the connection direction of at least two lamp modules 10 can be enhanced, so that the support plate 24 can be deformed in two mutually perpendicular directions at the same time.

[0063] In other optional embodiments, the support plate 24 and the carrier plate 21 can also be arranged to be relatively inclined, and the opposite ends of the connecting plate 25 are respectively connected to the support plate 24 and the carrier plate 21. Alternatively, the number of connecting plates 25 can be set to at least two, and at least two connecting plates 25 are arranged between the support plate 24 and the carrier plate 21 at intervals, and one end of each connecting plate 25 is connected to the support plate 24, and the other end of each connecting plate 25 is connected to the carrier plate 21. By arranging at least two connecting plates 25 between the support plate 24 and the carrier plate 21, the supporting capacity of the connecting plate 25 to the carrier plate 21 can be improved, so that the carrier plate 21 and the support plate 24 are respectively in contact with the opposite side walls of the buckle hole 168, so as to prevent the clamping member 20 from shaking. Among them, at least two connecting plates 25 can be parallel to each other, or can be arranged to be relatively inclined, which is not specifically limited in the embodiments of the present application.

[0064] Furthermore, in this embodiment, if Figure 7As shown, the support plate 24, the bearing plate 21 and the two undercuts 23 are symmetrically arranged about the symmetry plane of the connecting plate 25. Specifically, the support plate 24, the bearing plate 21 and the connecting plate 25 are all made of plates with uniform thickness, and the symmetry plane of the connecting plate 25 is the section II shown in the figure. By arranging the support plate 24, the bearing plate 21 and the two undercuts 23 symmetrically about the section II, not only can the opposite ends of the clamping member 20 be subjected to uniform force, but also the structure of the end cover 16 matched with the clamping member 20 can be consistent, so as to improve the production and installation efficiency.

[0065] Furthermore, if Figure 7 As shown, the undercut 23 has a guiding inclined surface, and at least a portion of the end surface of the bearing plate 21 is an inclined surface, which is coplanar with the corresponding guiding inclined surface on the undercut 23 .

[0066] Specifically, in this embodiment, the side of the end surface of the carrier plate 21 close to the undercut 23 is an inclined surface, and the inclination angle of the inclined surface relative to the plane where the carrier plate 21 is located is equal to the inclination angle of the guiding inclined surface relative to the plane where the carrier plate 21 is located, so that the inclined surface on the carrier plate 21 and the guiding inclined surface are coplanar. Through this arrangement, on the one hand, the size of the guiding inclined surface can be increased, so that the contact area of ​​the side wall of the buckle hole 168 with the undercut 23 is increased, which is convenient for driving the carrier plate 21 to deform; on the other hand, the thickness of the carrier plate 21 can be thinned, the strength of the carrier plate 21 can be reduced, and the toughness of the carrier plate 21 can be improved, so that the carrier plate 21 can be deformed.

[0067] Furthermore, in this embodiment, if Figure 7 As shown, a smooth transition between the surface of the carrier plate 21 facing away from the undercut 23 and the inclined surface can be provided.

[0068] Specifically, in this embodiment, the end face of the supporting plate 21 and the surface of the supporting plate 21 facing away from the undercut 23 are connected by a smooth arc surface to avoid wear on the end of the clip 20 and reduce the friction resistance when the clip 20 enters the clip hole 168.

[0069] like Fig. 9 As shown, Fig. 9 1 is a schematic diagram of the planar structure of the clamping member in another embodiment of the present application. In another embodiment, the end face of the carrier plate 21 can be set as a plane perpendicular to the plane where the carrier plate 21 is located, the undercut 23 is set at the end of the carrier plate 21, and the guide slope is connected to the end face of the carrier plate 21. By setting the end face of the carrier plate 21 as a plane perpendicular to the plane where the carrier plate 21 is located, when the undercut 23 is clamped with the side wall of the second opening 169, the end face of the carrier plate 21 can be abutted against the inner wall of the clamp hole 168, so as to form a limit at the opposite ends of the clamping member 20, so as to prevent the clamping member 20 from shaking in the clamp hole 168, thereby improving the stability of the clamping member 20.

[0070] Furthermore, in this embodiment, if Figure 7 As shown, the length of the support plate 24 is equal to the length of the carrier plate 21, and when the clips 20 are respectively clipped into the corresponding clip holes 168, the opposite side end surfaces of the support plate 24 and the carrier plate 21 respectively abut against the inner walls of the clip holes 168 to form limit stops at the opposite ends of the clips 20, thereby preventing the clips 20 from shaking in the clip holes 168, thereby improving the stability of the clips 20.

[0071] Alternatively, in other optional embodiments, the length of the support plate 24 may be set to be greater than the length of the bearing plate 21, or the length of the support plate 24 may be set to be less than the length of the bearing plate 21, which is not specifically limited in the embodiments of the present application.

[0072] In the above embodiment, the clamping member 20 is an integrally formed plastic member. For example, the integrally formed clamping member 20 can be formed by injection molding. The clamping member 20 formed by plastic injection molding has good elastic deformation ability, thereby improving the connection stability and the manufacturing efficiency of the clamping member 20.

[0073] In other optional embodiments, the clamping member 20 may also adopt an integral structure made of metal material, or adopt separately manufactured supporting plate 21, support plate 24 and connecting plate 25, and the supporting plate 21, support plate 24 and connecting plate 25 are fixedly connected by bonding or welding, etc., and the embodiments of the present application do not make specific limitations.

[0074] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the lamp 100 also includes a sealing ring 40, which is respectively arranged at the opposite ends of at least two lamp modules 10 and between two adjacent lamp modules 10 to seal the end of the lamp module 10 where the connector 165 is set to prevent the connector 165 from contacting with impurities such as liquid in the external environment and causing short circuit or damage.

[0075] Specifically, in this embodiment, the connectors 165 disposed at both ends of the lamp module 10 are inserted and matched with the electrical connector 30. Fig.10 and Fig.11 As shown, Fig.10 yes Figure 2 The local enlarged structural diagram of circle B in the figure is as follows: Fig.11 yes Fig.10Schematic diagram of the three-dimensional structure of the sealing ring in FIG. The sealing ring 40 includes an annular sealing body 42 and an abutting skirt 44 arranged at one end of the sealing body 42, the abutting skirt 44 is connected to the outer periphery of the sealing body 42 and extends in a direction away from the center of the sealing body 42, the sealing body 42 is sandwiched between the side wall of the connector 165 and the side wall of the electrical connector 30, and the abutting skirt 44 abuts against the end surface of the lamp module 10.

[0076] In this embodiment, by setting the connector 165 and the electrical connector 30 to be plugged in, the side wall of the electrical connector 30 and the side wall surrounding the connector 165 can be at least partially overlapped, and the sealing body 42 is clamped between the side wall of the connector 165 and the side wall of the electrical connector 30, so that the gap between the plugged connector 165 and the electrical connector 30 can be sealed to prevent liquid and other impurities in the external environment from entering the interior of the connector 165, thereby protecting the connector 165 and improving the electrical connection stability between the connector 165 and the electrical connector 30. In addition, the abutting skirt 44 abutting against the end face of the lamp module 10 can facilitate the positioning of the sealing body 42 to prevent the sealing body 42 from sliding relative to the electrical connector 30, and can also facilitate the grasping of the abutting skirt 44 to remove the sealing ring 40 from the lamp module 10, so as to facilitate the installation and removal of the sealing ring 40.

[0077] Among them, in this embodiment, if Fig.11 As shown, the abutting skirt 44 is provided in an annular shape, and the annular abutting skirt 44 is provided around the periphery of the sealing body 42 to enhance the strength of the sealing body 42. In another embodiment, the number of the abutting skirts 44 may also include at least two, and at least two abutting skirts 44 are evenly spaced around the circumference of the sealing body 42, which is not specifically limited in the embodiment of the present application.

[0078] Furthermore, in this embodiment, a groove 18 is provided on the end surface of the lamp module 10, and the connector 165 includes a pin 163 provided on the bottom wall of the groove 18, and the pin 163 is electrically connected to the light source 14.

[0080] Specifically, in this embodiment, the extension portion 46 is also arranged in a ring shape, and the extension portion 46 is connected to one end of the sealing body 42 away from the abutting skirt 44, and abuts on the bottom wall of the groove 18. In this way, on the one hand, the area of ​​the sealing body 42 clamped between the side wall of the connecting head 165 and the side wall of the electrical connector 30 can be increased to improve the sealing effect. On the other hand, the abutment between the extension portion 46 and the bottom wall of the groove 18 can also prevent the sealing body 42 from shaking.

[0081] Among them, in this embodiment, the cross-sectional shape of the extension portion 46 is the same as the cross-sectional shape of the sealing body 42, and the extension portion 46 and the sealing body 42 are an integral structure, so that the outer peripheral surface of the extension portion 46 and the outer peripheral surface of the sealing body 42 are coplanar, and the inner peripheral surface of the extension portion 46 and the inner peripheral surface of the sealing body 42 are coplanar. In this way, the production process of the sealing ring 40 can be simplified, and the side walls of the extension portion 46 and the connecting head 165 and the side walls of the electrical connector 30 can be more closely matched, thereby improving the sealing effect.

[0082] In another embodiment, an extension portion 46 may be provided to be bent and connected to the sealing body 42 to enhance the strength of the sealing body 42 .

[0084] Furthermore, if Fig.10 and Fig.11 As shown, in this embodiment, the sealing ring 40 includes a bottom plate 48, which is connected to one end of the extension portion 46 away from the sealing body 42 and covers the end face opening of the extension portion 46, and a avoidance opening 482 is provided on the bottom plate 48. The pin 163 passes through the avoidance opening 482 and passes through the bottom plate 48 to be plugged into the electrical connector 30.

[0085] Specifically, in this embodiment, the bottom plate 48 is connected to the inner peripheral wall of the annular extension 46 to form a cylindrical sealing ring 40. By providing the bottom plate 48 at the end of the extension 46, on the one hand, the strength of the extension 46 can be enhanced to prevent the assembly error of the sealing ring 40 from causing the end of the sealing ring 40 to curl, etc.; on the other hand, the bottom plate 48 can also further increase the sealing area to improve the sealing effect.

[0086] In this embodiment, the bottom plate 48 and the extension portion 46 are an integrated structure, which facilitates the installation and removal of the sealing ring 40 and can also reduce the production cost of the sealing ring 40. In other optional embodiments, the bottom plate 48 can also be made of a material different from the material used to make the extension portion 46. For example, the bottom plate 48 can be made of a material with a hardness coefficient greater than the hardness coefficient of the extension portion 46, and the bottom plate 48 and the inner wall of the extension portion 46 are connected by bonding or the like to improve the abutment strength of the bottom plate 48 against the end of the extension portion 46 to prevent the end of the extension portion 46 from being deformed.

By protruding the first annular protrusion 41 on the surface of the bottom plate 48 in contact with the electrical connector 30, the distance between the sealing ring 40 and the end surface of the electrical connector 30 can be further reduced, thereby enhancing the sealing effect.

[0088] The first annular protrusion 41 and the bottom plate 48 can be set as an integral structure to facilitate the installation and removal of the sealing ring 40, and can also reduce the production cost of the sealing ring 40. Alternatively, in other embodiments, the first annular protrusion 41 can also use an annular gasket, which can be bonded to the surface of the bottom plate 48, or can be detachably set from the bottom plate 48.
