[0039] In some connectors, the two matching connection terminals may be a male connector and a female connector, wherein the male connector may specifically be a pin structure, and correspondingly, the female connector is a structure into which the male connector can be inserted.

[0040] At present, the finger-proof protection structure for the male connector in the connector is an insulating sleeve structure provided at the end of the male connector, which can prevent the user's fingers from directly contacting the male connector. Such a finger-proof structure requires the male connector and the insulating sleeve to be assembled separately in the connector manufacturing process, resulting in complicated connector manufacturing process.

The second connection part is located in the first cavity of the second shell, and there is a gap between the second connection part and the second opening, so that the second connection part is located in the second cavity as a whole. In this way, even if the user's finger touches the first opening of the first shell and the second opening of the second shell, there is still a certain distance between the user's finger and the first connection part and the second connection part, thereby preventing the user's finger from touching the first connection part and the second connection part, so as to prevent the user from getting an electric shock. The first shell will sheath at least part of the second shell inside, and at least part of the second connection part is also located in the first cavity, so that the first connection part and the second connection part can be in contact, so that the first connection part and the second connection part can be electrically connected, thus realizing the electrical connection between the first connection member and the second connection member of the connection assembly.

[0042] In the connector proposed in the present application, due to the application of the above-mentioned connecting assembly, the connector can have an anti-finger touch function, and the structure is relatively simple, and there is no need to separately assemble an anti-finger touch structure, thereby making the preparation process of the connector relatively simple and improving the preparation efficiency of the connector.

[0043] The connection assembly and connector provided in the present application are described in detail below in conjunction with specific embodiments.

[0044] The present application embodiment proposes a connection component, referring to Figures 1 to 4 As shown, it includes a first connector 100 and a second connector 200, and the first connector 100 and the second connector 200 can be electrically connected. The connection assembly can be applied to a connector.

[0045] The first connector 100 includes a first shell 110 and a first connecting portion 120. The first shell 110 is the basic component of the first connector 100 of the present application. The first shell 110 can provide a mounting base for at least some of the other components of the first connector 100 and protect at least some of the other components. The first shell 110 has a first cavity 111, and the surface of the first shell 110 is provided with a first opening 112 that is connected to the first cavity 111. The first connecting portion 120 is arranged in the first cavity 111 of the first shell 110. When preparing and assembling the first connector 100, the first connecting portion 120 can be assembled in the first cavity 111 through the first opening 112. The first connecting portion 120 is an electrical connector, and the first connecting portion 120 can be electrically connected to an external electrical device, so the first connecting portion 120 can be electrically conductive. The first connection portion 120 and the first opening 112 have a certain distance, so that the first connection portion 120 is entirely located in the first cavity 111. In this way, even if the user's finger touches the first opening 112 of the first shell 110, the user's finger cannot touch the first connection portion 120 located in the first cavity 111, thereby preventing the user from being electrocuted and making it safer and more reliable for the user to operate the first connection member 100.

[0046] The second connector 200 includes a second shell 210 and a second connecting portion 220. The second shell 210 is the basic component of the second connector 200 of the present application. The second shell 210 can provide a mounting base for at least some of the other components of the second connector 200 and protect at least some of the other components. The second shell 210 has a second cavity 211, and the surface of the second shell 210 is provided with a second opening 212 that communicates with the second cavity 211. The second connecting portion 220 is arranged in the second cavity 211 of the second shell 210. When preparing and assembling the second connector 200, the second connecting portion 220 can be assembled in the second cavity 211 through the second opening 212. The second connecting portion 220 is an electrical connector, and the second connecting portion 220 can be electrically connected to an external electrical device, so the second connecting portion 220 can be electrically conductive. The second connection part 220 and the second opening 212 have a certain distance, so that the second connection part 220 is located in the second cavity 211 as a whole. In this way, even if the user's finger touches the second opening 212 of the second shell 210, the user's finger cannot touch the second connection part 220 located in the second cavity 211, thereby preventing the user from being electrocuted, making it safer and more reliable for the user to operate the second connection member 200.

[0047] The first connection part 120 and the second connection part 220 can be electrically connected to different electrical devices respectively, and the first connection part 120 and the second connection part 220 are also electrically connected, so that different electrical components can be electrically connected through the first connection part 120 and the second connection part 220, so that the connection component of the present application can be electrically connected to different electrical devices.

[0048] Specifically, the first shell 110 can detachably sleeve at least a portion of the second shell 210 therein, so that at least a portion of the second connection portion 220 disposed in the second cavity 211 can also be located in the first cavity 111, so that the first connection portion 120 and the second connection portion 220 are disposed close to each other, and finally the first connection portion 120 and the second connection portion 220 are detachably contacted and electrically connected. Since the first connection portion 120 and the second connection portion 220 are both electrical connectors, the first shell 110 and the second shell 210 can be made of polymer materials, so that the first shell 110 and the second shell 210 have a certain structural strength while being relatively light in weight and being insulating parts. This can further reduce the risk of electric shock to users.

[0049] When the first connection part 120 is connected to the second connection part 220, the first connection part 120 and the second connection part 220 can be electrically connected. The first connection part 120 and the second connection part 220 can also be separated, and the first shell 110 and the second shell 210 can also be separated, so that the first connection part 120 and the second connection part 220 can be electrically disconnected, so that the electrical device electrically connected to the first connection part 120 and the electrical device electrically connected to the second connection part 220 can be connected or disconnected.

[0050] In some embodiments, reference Figures 1 to 4 As shown, the first shell 110 of the present application can be sleeved on the first connecting portion 120, so that the first connecting portion 120 is more stable when it is set in the first cavity 111 of the first shell 110, and the first connecting portion 120 is prevented from falling out of the first cavity 111. Specifically, the inner diameter of the first cavity 111 of the first shell 110 can be set to match the outer diameter of the first connecting portion 120, so that the outer wall of the first connecting portion 120 can be aligned with the inner wall of the first cavity 111, so that the first connecting portion 120 can be embedded in the first cavity 111, so that the first connecting portion 120 can be tightly connected to the first shell 110. Specifically, the first connecting portion 120 can be fixed in the first cavity 111 of the first shell 110 by interference fit.

[0051] In some embodiments, reference Figure 3 and Figure 5As shown, the first cavity 111 of the first shell 110 can be specifically configured to include a first sub-cavity 111a and a second sub-cavity 111b. One end of the first sub-cavity 111a is connected to one end of the second sub-cavity 111b, and the end of the first sub-cavity 111a facing away from the second sub-cavity 111b is connected to the first opening 112. Part of the first connecting portion 120 can be arranged in the first sub-cavity 111a, and the other part of the second connecting portion 220 can be arranged in the second sub-cavity 111b. The outer wall of the part of the first connecting portion 120 located in the second sub-cavity 111b can be fitted with the inner wall of the second sub-cavity 111b, so that the first connecting portion 120 can be snapped into the second sub-cavity 111b, so as to achieve the purpose of fixing the first connecting portion 120 in the first shell 110. The outer wall of the first connecting portion 120 located in the first sub-cavity 111a is spaced a certain distance from the inner wall of the first sub-cavity 111a, so that when the first shell 110 is sleeved in the second shell 210, the gap between the first sub-cavity 111a and the first connecting portion 120 allows the second shell 210 to extend into, thereby avoiding mutual interference between the first shell 110 and the second shell 210.

[0052] In some embodiments, reference Figure 4 As shown, the second shell 210 of the present application can be sleeved on the second connecting portion 220, so that the second connecting portion 220 is more stable when it is set in the second cavity 211 of the second shell 210, and the second connecting portion 220 is prevented from falling out of the second cavity 211. Specifically, the inner diameter of the second cavity 211 of the second shell 210 can be set to match the outer diameter of the second connecting portion 220, so that the outer wall of the second connecting portion 220 can be aligned with the inner wall of the second cavity 211, so that the second connecting portion 220 can be embedded in the second cavity 211, so that the second connecting portion 220 can be tightly connected to the second shell 210. Specifically, the second connecting portion 220 can be fixed in the second cavity 211 of the second shell 210 by interference fit.

[0053] In some embodiments, reference Figure 3 and Figure 5As shown, a first protrusion 130 may be provided on the inner wall of the first cavity 111 of the first housing 110 of the present application, and the first protrusion 130 is a protruding solid structure on the inner wall of the first cavity 111. A first limiting groove 213 may be provided on the outer wall of the second housing 210, and the groove size of the first limiting groove 213 matches the outer size of the first protrusion 130, so that when the first housing 110 is sleeved on the second housing 210, the first protrusion 130 may be embedded in the first limiting groove 213. The inner wall of the first limiting groove 213 may serve the purpose of limiting the first protrusion 130, so that the first protrusion 130 and the inner wall of the first limiting groove 213 are mutually limited, so that the first housing 110 and the second housing 210 can be mutually limited, and when the first housing 110 is sleeved on the second housing 210, the first housing 110 and the second housing 210 can be prevented from relative movement in the axial direction thereof, so that the connection effect of the first connecting portion 120 and the second connecting portion 220 is more stable and reliable.

[0054] The second shell 210 can be prepared by a mold injection molding process. By setting the first limiting groove 213 on the outer wall of the second shell 210, the material used for the second shell 210 can be reduced, so that the preparation cost of the second shell 210 is reduced, and thus the preparation cost of the connection component of the present application can be reduced.

[0055] The inner diameter of the first sub-cavity 111a of the first shell 110 can be set to be slightly larger than the outer diameter of the second shell 210, so that the outer wall of the part of the second shell 210 extending into the first sub-cavity 111a of the first shell 110 can have a certain gap with the outer wall of the first sub-cavity 111a, which makes it convenient to connect or separate the first shell 110 and the second shell 210.

[0056] In addition, in other embodiments, the inner wall of the first cavity 111 of the first shell 110 of the present application may not need to be provided with the first protrusion 130, and the inner diameter of the first sub-cavity 111a may be set to match the outer diameter of the second shell 210, so that the outer wall of the second shell 210 can fit the inner wall of the first sub-cavity 111a. In this way, the friction force between the first shell 110 and the second shell 210 can also limit the first shell 110 and the second shell 210 in the circumferential direction of the first shell 110 and the second shell 210, and prevent the first shell 110 and the second shell 210 from rotating relative to each other.

[0057] In some embodiments, reference Figure 3 and Figure 5As shown, the number of first protrusions 130 provided in the first shell 110 of the present application may be multiple, and the multiple first protrusions 130 may be provided at intervals along the circumference of the first shell 110. Multiple first limiting grooves 213 may be provided on the outer side wall of the second shell 210, and the number of the first limiting grooves 213 may be consistent with the number of the first protrusions 130, so that when the first shell 110 is sleeved on the second shell 210, the multiple first protrusions 130 may be respectively embedded in the multiple first limiting grooves 213. The multiple weight-reducing grooves 113 are provided on the outer side wall of the second shell 210, which can further reduce the material used when the second shell 210 is prepared by the mold injection molding process, thereby further reducing the preparation cost of the connection assembly of the present application.

[0058] In addition, when a plurality of first protrusions 130 are provided in the first cavity 111 of the first shell 110, the first cavity 111 of the first shell 110 also includes a plurality of second limiting grooves 111c located between adjacent first protrusions 130. When a plurality of first limiting grooves 213 are provided on the outer wall of the second shell 210, the outer wall of the second shell 210 also includes a plurality of second protrusions 230 located between adjacent first limiting grooves 213. The plurality of second protrusions 230 can be respectively embedded in the plurality of second limiting grooves 111c, and the second protrusions 230 and the second limiting grooves 111c can also limit each other.

[0059] In some embodiments, reference Figure 3 , Figure 5 and Figure 6 As shown, the first housing 110 of the present application can be specifically configured to include a first housing portion 114 and a second housing portion 115. The first sub-cavity portion 111a is located in the first housing portion 114, and the second sub-cavity portion 111b is located in the second housing portion 115. The first housing portion 114 sleeves the second housing portion 115, so that the second sub-cavity portion 111b is also located in the first sub-cavity portion 111a, which can make the structure of the first housing 110 more compact.

[0060] At least part of the outer wall of the second shell portion 115 has a certain gap with the inner wall of the first shell portion 114. Specifically, the second limiting groove 111c in the first shell portion 114 can be set in the gap between the first shell portion 114 and the second shell portion 115, which can further make the axial dimension of the first shell 110 more compact.

[0061] In some embodiments, reference Figure 5As shown, a weight-reducing groove 113 may be provided on the outer wall of the first shell 110 of the present application, and the weight-reducing groove 113 may be provided corresponding to the first protrusion 130 in the first shell 110. The first shell 110 may also be prepared by a mold injection molding process, and by providing the weight-reducing groove 113, the materials required for preparing the first shell 110 may be reduced, thereby reducing the preparation cost of the first shell 110, and further reducing the preparation cost of the connection assembly of the present application.

[0062] In some embodiments, reference Figure 4 As shown, the first limiting groove 213 on the outer wall of the second shell 210 of the present application can be connected to the second cavity 211, so that the first limiting groove 213 is a hollow groove structure opened on the outer wall of the second shell 210, thereby further reducing the amount used in the preparation of the second shell 210, so as to further reduce the preparation cost of the connecting component.

[0063] Specifically, the first limiting groove 213 may be a strip-shaped hole disposed on the outer side wall of the second shell 210 . The first limiting groove 213 may be disposed along the axial direction of the second shell 210 , and the second limiting groove 111 c may also be disposed along the axial direction of the first shell 110 .

[0064] In some embodiments, reference Figure 4 As shown, the connection assembly of the present application may also be provided with a stopper 300, and the stopper 300 may be opposite to the second housing 210, or may be arranged around the second housing 210, so that the stopper 300 may be opposite to the outer side wall of the second housing 210. The stopper 300 and the second stopper groove 111c of the second housing 210 may be spaced apart, and the gap between the stopper 300 and the second stopper groove 111c may be set so that the user's finger cannot be inserted, so that the user's finger can be prevented from being inserted into the second stopper groove 111c and contacting the second connection portion 220, so as to prevent the user's finger from being electrocuted.

[0065] In some embodiments, reference Figure 2 As shown, the first connection part 120 of the present application can adopt a male end connector, and correspondingly, the second connection part 220 can adopt a female end connector, so that the first connection part 120 and the second connection part 220 are adapted to be electrically connected. Specifically, when the first connection part 120 is connected to the second connection part 220, the second connection part 220 can be sleeved on the first connection part 120, and the outer wall of the first connection part 120 contacts the inner wall of the second connection part 220, so that the first connection part 120 and the second connection part 220 are electrically connected.

[0066] Based on the above connection component, an embodiment of the present application further proposes a connector, including the above connection component.

[0067] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
