[0039] In the connector, the male pin part and the female pin part are electrically connected by plugging in. In some connectors, such as the floating connector in the drawer, the male pin part and the female pin part need to be provided with corresponding guide structures so that the male pin part and the female pin part can be plugged in smoothly.

[0040] At present, the guide structure in the connector adopts a plastic structural part, which makes the cost of the guide structure of the connector relatively low, thereby making the cost of the connector low, but the durability and reliability of the guide structure made of plastic are poor.

[0041] In the housing assembly proposed in the present application, the first housing can be used to install the first electrical connector, and the second housing can be used to install the second electrical connector. The plug connector can be detachably embedded in the plug hole, so that the plug connector is fixed in the plug hole, so that the first housing and the second housing are fixed, so that the first electrical connector provided in the first housing and the second electrical connector provided in the second housing can be plugged in and electrically connected. The plug connector can also be removed from the plug hole, so that the plug connector is separated from the plug hole, so that the first housing and the second housing can be relatively movable, so that the first electrical connector provided in the first housing and the second electrical connector provided in the second housing can be separated and disconnected.

[0042] The first plug-in part of the plug-in connector is sleeved on the second plug-in part, so that the second plug-in part can support the first plug-in part inside the first plug-in part. The first plug-in part is made of plastic material, so that the overall weight of the plug-in connector is relatively small, and the preparation cost is relatively low, so that the preparation cost of the shell assembly of the present application is relatively low. The structural strength of the second plug-in part is greater than that of the first plug-in part, which can make the overall structural strength of the plug-in connector better, so that the reliability and durability of the plug-in connector are better, so that the reliability and durability of the shell assembly of the present application are better at a relatively low cost.

[0043] In the connector proposed in the present application, the first electrical connector and the second electrical connector are respectively arranged on the first shell and the second shell, and the first shell and the second shell are docked, so that the first electrical connector and the second electrical connector can be connected or separated. The connector uses the above-mentioned shell assembly, so that the reliability and durability of the connector are better, and the preparation cost is relatively low.

[0044] The housing assembly and connector provided in the present application are described in detail below in conjunction with specific embodiments.

[0045] The present application embodiment provides a housing assembly, referring to Figures 1 to 4 As shown, it includes a first housing 100, a second housing 200 and a plug-in connector 300. The housing assembly can be applied to a connector.

[0046] Among them, the first shell 100 and the second shell 200 are basic components of the shell assembly of the present application. The first shell 100 and the second shell 200 can provide an installation basis for at least some of the other components of the shell assembly and protect at least some of the other components.

[0047] Specifically, the first shell 100 and the second shell 200 are arranged opposite to each other, the first shell 100 can be used to carry and install the first electrical connector, and the second shell 200 can be used to carry and install the second electrical connector, and the first electrical connector and the second electrical connector can be plugged in or separated. When the first electrical connector and the second electrical connector are plugged in, the first electrical connector and the second electrical connector can be electrically connected, and when the first electrical connector and the second electrical connector are separated, the first electrical connector and the second electrical connector can be disconnected. The first shell 100 and the second shell 200 can be made of polymer materials, so that the first shell 100 and the second shell 200 have a certain structural strength while being relatively light in weight and being insulating parts.

[0048] The plug connector 300 is disposed on the second housing 200. The first housing 100 is provided with a plug hole 110. The plug connector 300 is detachably embedded in the plug hole 110 of the first housing 100. Specifically, the plug connector 300 has a first state and a second state. When the plug connector 300 is in the first state, the plug connector 300 is embedded in the plug hole 110, so that the plug connector 300 can be fixed in the plug hole 110, thereby fixing the first housing 100 and the second housing 200. When the plug connector 300 is in the second state, the plug connector 300 is located outside the plug hole 110, so that the first housing 100 and the second housing 200 can move relative to each other.

[0049] Specifically, when the first housing 100 and the second housing 200 are arranged opposite to each other, one end of the plug connector 300 is opposite to the opening of the plug hole 110. When the plug connector 300 is switched from the second state to the first state, the second housing 200 can move toward the first housing 100, so that one end of the plug connector 300 facing the plug hole 110 can extend into the plug hole 110. In this way, the first electrical connector arranged in the first housing 100 and the second electrical connector arranged in the second housing 200 can move toward each other and plug in, so that the first electrical connector and the second electrical connector can be plugged in and connected. In the process of the plug connector 300 moving toward the plug hole 110, the plug hole 110 cooperates with the plug connector 300 and can also limit the plug connector 300 and the plug hole 110 to each other, thereby playing a guiding role in the process of the first housing 100 and the second housing 200 docking, so that the first electrical connector and the second electrical connector can be plugged in and connected more accurately.

[0050] When the plug connector 300 switches from the first state to the second state, the second housing 200 can move away from the first housing 100, so that the plug connector 300 is removed from the plug hole 110. In this way, the first electrical connector provided in the first housing 100 and the second electrical connector provided in the second housing 200 can move away from each other and separate, so that the first electrical connector and the second electrical connector are disconnected.

[0051] The plug connector 300 includes a first plug connector 310 and a second plug connector 320. The first plug connector 310 is sleeved on the second plug connector 320 so that the second plug connector 320 can support the first plug connector 310. The outer wall of the second plug connector 320 is fitted with the inner wall of the first plug connector 310 so that the second plug connector 320 can be tightly arranged in the first plug connector 310. The material of the first plug connector 310 is a polymer material, and the second plug connector 320 can be made of a material with a structural strength greater than that of the first plug connector 310, so that the second plug connector 320 has a better structural strength. In this way, the second plug connector 320 can better support the first plug connector 310, so that the overall structural strength of the plug connector 300 of the present application is better, and then the reliability and durability of the housing assembly are better. The first plug-in portion 310 is made of plastic material, so that the weight of the first plug-in portion 310 is relatively light and the manufacturing cost is relatively low, which can make the manufacturing cost of the housing assembly relatively low.

[0052] In some embodiments, the first plug-in portion 310 may be made of a plastic structural member, so that the manufacturing cost of the first plug-in portion 310 is relatively low. The second plug-in portion 320 may be made of a metal structural member, that is, the second plug-in portion 320 is made of metal, so that the second plug-in portion 320 has a better structural strength. Specifically, the second plug-in portion 320 may be made of aluminum alloy, magnesium alloy, or iron alloy.

[0053] In some embodiments, reference Figure 3 As shown, the first plug-in part 310 of the present application may be provided with a mounting hole 311, and correspondingly, the surface of the first plug-in part 310 has a mounting hole 312 that is connected to the mounting hole 312. The second plug-in part 320 may extend into the mounting hole 311 of the first plug-in part 310 through the mounting hole 311 on the surface of the first plug-in part 310, so that the first plug-in part 310 sleeves the second plug-in part 320 therein. Therefore, after the first plug-in part 310 and the second plug-in part 320 are prepared separately, the second plug-in part 320 may be fixed in the mounting hole 311 through the mounting hole 312, so that the preparation method of the plug connector 300 is simple and convenient. The hole shape and size of the mounting hole 311 can be set to match the outer dimensions of the second plug-in part 320, so that the second plug-in part 320 can be embedded in the first plug-in part 310. In this way, the second plug-in part 320 can be tightly connected with the first plug-in part 310 to prevent the second plug-in part 320 from falling off from the mounting hole 311 of the first plug-in part 310.

[0054] Specifically, the installation opening 312 of the first plug-in portion 310 can be arranged on the first side of the first plug-in portion 310 facing away from the plug-in hole 110 of the first shell 100, so that the side of the first plug-in portion 310 facing the plug-in hole 110 is a closed end face, which can make the plug-in effect between the first plug-in portion 310 and the plug-in hole 110 more stable and reliable.

[0055] In some embodiments, the second plug-in portion 320 of the present application may be an injection molded structural member, and the second plug-in portion 320 may be formed in the mounting hole 311 of the first plug-in portion 310 by an injection molding process. In this way, the second plug-in portion 320 may fully fill the mounting hole 311 of the first plug-in portion 310, so that the second plug-in portion 320 is tightly connected to the first plug-in portion 310.

[0056] The first plug part 310 of the present application may also be an injection molded structural part. Specifically, when preparing the plug connector 300 of the present application, the first plug part 310 may be prepared by a mold injection molding process, so that the first plug part 310 has a mounting hole 311. The first plug part 310 with the mounting hole 311 may be used as a mold for injection molding of the second plug part 320. The second plug part 320 is formed by injection molding in the mounting hole 311 of the first plug part 310, so that the outer wall of the second plug part 320 is fitted and connected with the inner wall of the mounting hole 311, so that the second plug part 320 can better support the first plug part 310, thereby making the structural strength of the plug connector 300 better.

[0057] In some embodiments, reference Figure 3As shown, in addition to the injection molding structure, the second plug-in part 320 of the present application can also be connected to the first plug-in part 310 by threaded connection. Specifically, the inner wall of the mounting hole 311 of the first plug-in part 310 can be provided with an internal thread, and the outer wall of the second plug-in part 320 can be provided with an external thread, and the external thread of the second plug-in part 320 is matched with the internal thread of the first plug-in part 310. In this way, the second plug-in part 320 can be screwed into the mounting hole 311 of the first plug-in part 310, so that the second plug-in part 320 is fixed in the first plug-in part 310.

[0058] Specifically, when preparing the plug connector 300, the first plug connector 310 having the mounting hole 311 can be prepared by a mold injection process, and the inner wall of the mounting hole 311 can be a smooth surface. The second plug connector 320 having an external thread is tapped into the mounting hole 311 of the first plug connector 310, thereby forming an internal thread on the inner wall of the mounting hole 311 of the first plug connector 310, so that the second plug connector 320 is fixed in the mounting hole 311 of the first plug connector 310 by threaded connection.

[0059] In addition, in other embodiments, the second plug-in portion 320 can also be fixed in the mounting hole 311 of the first plug-in portion 310 by interference fit. Specifically, the inner diameter of the mounting hole 311 of the first plug-in portion 310 can be set to be smaller than the outer diameter of the second plug-in portion 320. When the second plug-in portion 320 is embedded in the mounting hole 311 of the first plug-in portion 310, the outer wall of the second plug-in portion 320 can be tightly fitted with the inner wall of the mounting hole 311 of the first plug-in portion 310.

[0060] In some embodiments, reference Figure 3 and Figure 5As shown, when the second plug-in portion 320 of the present application is fixed in the mounting hole 311 of the first plug-in portion 310 by threaded connection, the mounting hole 311 of the first plug-in portion 310 can be configured to include a first hole section 311a and a second hole section 311b. The first hole section 311a and the second hole section 311b are connected, and one end of the first hole section 311a facing away from the second hole section 311b is connected to the mounting port 312, and the inner diameter of the first hole section 311a is greater than the inner diameter of the second hole section 311b, so that there is a step structure between the first hole section 311a and the second hole section 311b. The second plug-in portion 320 can be a screw structural member, and one end of the second plug-in portion 320 facing away from the bottom wall of the mounting hole 311 is the head of the screw, and the outer diameter is relatively large. When the second plug-in part 320 is fixed in the mounting hole 311 of the first plug-in part 310, the main part of the second plug-in part 320 can be arranged in the second hole section 311b, and the head part of the second plug-in part 320 with a relatively large outer diameter can be located in the first hole section 311a, so that the second plug-in part 320 can be located as a whole in the mounting hole 311 of the first plug-in part 310, and the step structure between the first hole section 311a and the second hole section 311b can also serve the purpose of limiting the second plug-in part 320, thereby preventing the second plug-in part 320 from excessively rotating when it is screwed into the mounting hole 311 of the first plug-in part 310.

[0061] In some embodiments, the first housing 100 and the second housing 200 of the present application may also be made of plastic material, and the first housing 100 and the second housing 200 may be prepared by a mold injection molding process. The first plug-in portion 310 of the plug-in connector 300 and the second housing 200 may be an integral structure, and the first plug-in portion 310 and the second housing 200 may be integrally formed by a mold injection molding process. This makes the connection effect between the first plug-in portion 310 and the second housing 200 more reliable, and further makes the connection effect between the plug-in connector 300 and the second housing 200 more stable and reliable.

[0062] In some embodiments, reference Figure 6 As shown, a weight-reducing groove 313 may be provided on the outer side wall of the first plug-in part 310 of the present application. The weight-reducing groove 313 is a groove structure provided on the outer side wall of the first plug-in part 310 and recessed into the first plug-in part 310. The weight-reducing groove 313 may be provided to reduce the weight of the first plug-in part 310 and reduce the materials used in the preparation of the first plug-in part 310. The number of the weight-reducing grooves 313 may be multiple, and the multiple weight-reducing grooves 313 may be provided at intervals along the circumference of the first plug-in part 310, so that the weight of the first plug-in part 310 may be further reduced and the materials used in the preparation of the first plug-in part 310 may be reduced.

[0063] The surface of the first plug-in portion 310 also has a connecting surface 314 located between adjacent weight-reducing grooves 313, and the two ends of the connecting surface 314 are respectively connected to the adjacent weight-reducing grooves 313, and the connecting surface 314 and the connection between the connecting surface 314 and the weight-reducing grooves 313 are both arc surfaces. This can avoid having a sharp structure on the surface of the first plug-in portion 310, thereby making it safer and more reliable for users to use the shell assembly and connector of the present application.

[0064] In some embodiments, reference Figure 1 and Figure 4 As shown, the number of the plug holes 110 on the first housing 100 of the present application can be set to multiple, and accordingly, the number of the plug connectors 300 can also be set to multiple, and the multiple plug connectors 300 can be arranged in correspondence with the multiple plug holes 110, so that the multiple plug connectors 300 can be respectively plugged into the multiple plug holes 110. In this way, when the first housing 100 and the second housing 200 are relatively moved and plugged, the multiple plug connectors 300 can cooperate and guide with the multiple plug holes 110, so that the first housing 100 and the second housing 200 can be docked more smoothly, and then the first electrical connector set on the first housing 100 and the second electrical connector set on the second housing 200 can be docked more smoothly.

[0065] The number of the plug holes 110 of the first housing 100 can be two, and the two plug holes 110 can be disposed on both sides of the first housing 100 . The number of the plug connectors 300 can also be two, and the two plug connectors 300 can be disposed on both sides of the second housing 200 .

[0066] Based on the above housing assembly, the present application also proposes a connector, including a first electrical connector, a second electrical connector and the above housing assembly, wherein the first electrical connector is disposed on the first housing 100, the second electrical connector is disposed on the second housing 200, and the first electrical connector and the second electrical connector are opposite to each other.

[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.
