[0045] In order to have insulation properties, the shell of the connector is made of polymer materials through injection molding. After long-term use of the connector, the shell will be deformed due to environmental influences, resulting in damage to the sealing of the shell.

[0046] At present, in connector design, in order to prevent the shell from deforming after long-term use, the thickness of the shell is increased to improve the strength of the shell. However, such a design method leads to an increase in the manufacturing cost of the connector shell and an increase in the difficulty of the manufacturing process.

[0047] In the shell assembly proposed in the present application, the opening of the shell is docked with the base, so that the opening of the shell can be sealed by the base. The base is connected to the shell by a connector, so that the base and the shell can be fixed. The inner cavity of the shell can be used to accommodate the electrical connector, and the external electrical connection structure can be inserted into the inner cavity of the shell through the plug interface of the shell and electrically connected to the electrical connector.

When the shell has a tendency to expand and deform outward due to factors such as ambient temperature and humidity, the limiter can abut against the outer wall of the shell, so that the outer wall of the shell cannot expand and deform outward, so that the effect of the opening of the shell and the base being combined is stable and reliable, and the opening of the shell is kept in a sealed state. This can prevent external dirty impurities from entering the shell through the opening of the shell and causing damage to the electrical connector arranged in the inner cavity of the shell.

[0048] In the connector proposed in the present application, the electrical connector is arranged on the base and is located in the inner cavity of the shell, so that the shell can protect the electrical connector. The limiter limits the shell to prevent the shell from expanding outward and deforming, so that the connection effect between the shell and the base is more stable and reliable, so that the part of the electrical connector located in the inner cavity of the shell can be fully protected by the shell, so that the durability and reliability of the connector of the present application are better.

[0049] The housing assembly and the connector provided in the present application are described in detail below in conjunction with specific embodiments.

[0050] The present application embodiment provides a housing assembly, referring to Figures 1 to 4 As shown, it includes a base 100, a housing 200, a first stopper 300 and a connector 600. The housing assembly can be used in a connector.

[0051] The base 100 is a basic component of the housing assembly of the present application. The base 100 can provide a mounting base for at least some of the other components of the housing assembly and protect at least some of the other components. The base 100 can be made of metal material, so that the base 100 has a better structural strength, thereby making the durability and reliability of the base 100 better. Of course, the base 100 can also be made of polymer material, so that the base 100 has a certain structural strength and is relatively light.

[0052] The housing 200 is disposed on the base 100, and an inner cavity 221 is provided in the housing 200. An opening 211 and an insertion port 222 are provided on the surface of the housing 200, and both the opening 211 and the insertion port 222 of the housing 200 are in communication with the inner cavity 221 of the housing 200. The inner cavity 221 of the housing 200 can be used to accommodate an electrical connector. When the housing assembly of the present application is used in a connector, the electrical connector is disposed in the inner cavity 221 of the housing 200. The opening 211 of the housing 200 is docked with the base 100, so that the base 100 can be blocked in the opening 211 of the housing 200, so that the opening 211 of the housing 200 can be sealed. The plug interface 222 of the shell 200 can be used for external lines to pass through. Specifically, the connection end of the external electrical connector can extend into the inner cavity 221 of the shell 200 through the plug interface 222 of the shell 200 and connect with the electrical connector, so that the electrical connector in the inner cavity 221 of the shell 200 can be electrically connected to the external electrical connector.

[0053] Since the electrical connector is disposed in the housing 200 , in order to make the connector of the present application safe to use, the housing 200 is made of insulating material, and specifically, can be made of polymer material through an injection molding process.

[0054] The connecting member 600 is disposed between the base 100 and the shell 200 , and is connected to both the base 100 and the shell 200 , so that the base 100 and the shell 200 can be fixed by the connecting member 600 , thereby allowing the shell 200 to be stably and reliably disposed on the base 100 .

[0055] The first stopper 300 is also disposed on the base 100, so that the first stopper 300 can be fixed, the first stopper 300 is located outside the inner cavity 221 of the shell 200, and the first stopper 300 is opposite to and abuts against the outer wall of the shell 200, so that the first stopper 300 can be limited and matched with the shell 200 in a direction perpendicular to the direction from the shell 200 to the base 100. When the shell 200 is deformed by factors such as temperature and humidity in the environment, the shell 200 has a tendency to expand and deform outward, that is, the outer wall of the shell 200 has a tendency to move toward the first stopper 300, so that the outer wall of the shell 200 can abut against the first stopper 300. Since the first stopper 300 is fixed on the base 100, the first stopper 300 can limit the outer wall of the shell 200, and the tendency of the shell 200 to expand and deform outward is suppressed by the first stopper 300, so that the outer structure of the shell 200 can remain unchanged to a certain extent. In this way, the connection effect between the opening 211 of the shell 200 and the base 100 is more reliable, and the opening 211 of the shell 200 can always remain sealed, and external impurities and dirt cannot enter the shell 200 through the opening 211 of the shell 200, thereby achieving the purpose of protecting the electrical connectors arranged in the shell 200.

[0056] In some embodiments, reference Figure 1 and Figure 2 As shown, the first position-limiting member 300 of the present application may be configured to include a plurality of first position-limiting portions 310, and the plurality of first position-limiting portions 310 may be arranged along the circumference of the housing 200, and the plurality of first position-limiting portions 310 are all opposite to the outer wall of the housing 200. In this way, the plurality of first position-limiting portions 310 may be arranged around the housing 200, and when the circumferential outer wall of the housing 200 has an outward expansion tendency, the plurality of first position-limiting portions 310 may limit various parts of the circumferential outer wall of the housing 200, thereby preventing the housing 200 from deforming in various directions.

[0057] Specifically, when the cross section of the housing 200 in the direction from the housing 200 to the base 100 is a rectangular cross section, the housing 200 has four side walls, and accordingly, the number of the first limiting portions 310 can be set to four, and the four first limiting portions 310 can be respectively opposite to the four outer walls of the housing 200, so that the four first limiting portions 310 can limit the four outer walls of the housing 200 respectively. When the circumferential outer wall of the housing 200 expands and deforms outward as a whole, the four first limiting portions 310 prevent the four outer walls of the housing 200 from expanding and deforming outward. Any one of the first limiting portions 310 can be set to be opposite to the center of the outer wall of the corresponding housing 200, so that the side wall of the housing 200 can be more fully limited by the limiting effect of the first limiting portions 310, thereby further reducing the degree of deformation of the housing 200 caused by the influence of the environment.

[0058] In some embodiments, the housing assembly of the present application may also be provided with a second stopper, which is also provided on the base 100 and is located in the inner cavity 221 of the housing 200, so that the second stopper can be opposite to the inner wall of the housing 200, and the second stopper is fixed on the base 100. In this way, the second stopper can be limited and matched with the housing 200 in a direction perpendicular to the direction from the housing 200 to the base 100. When the housing 200 is deformed by factors such as temperature and humidity in the environment, the housing 200 has a tendency to shrink and deform inwardly, that is, the inner wall of the housing 200 has a tendency to move toward the second stopper, so that the inner wall of the housing 200 can be offset against the second stopper. Since the second stopper is fixed on the base 100, the second stopper can limit the inner wall of the housing 200, and the tendency of the housing 200 to shrink and deform inwardly is suppressed by the second stopper, so that the outer structure of the housing 200 can remain unchanged to a certain extent. In this way, the connection effect between the opening 211 of the shell 200 and the base 100 is more reliable, and the opening 211 of the shell 200 can always remain sealed, and external impurities and dirt cannot enter the shell 200 through the opening 211 of the shell 200, thereby achieving the purpose of protecting the electrical connectors arranged in the shell 200.

[0059] The second position-limiting member may be configured to include a plurality of second position-limiting portions, and the plurality of second position-limiting portions may be disposed along the circumference of the housing 200, and the plurality of second position-limiting portions are all opposite to the inner wall of the housing 200. In this way, the plurality of second position-limiting portions may be disposed around the housing 200, and when the circumferential inner wall of the housing 200 has an outward expansion tendency, the plurality of second position-limiting portions may limit various parts of the circumferential inner wall of the housing 200, thereby preventing the housing 200 from deforming in various directions.

[0060] Specifically, when the cross section of the housing 200 in the direction from the housing 200 to the base 100 is a rectangular cross section, the housing 200 has four side walls, and accordingly, the number of the second limiting portions can be set to four, and the four second limiting portions can be respectively opposite to the four inner walls of the housing 200, so that the four second limiting portions can respectively limit the four inner walls of the housing 200. When the circumferential inner wall of the housing 200 shrinks and deforms inward as a whole, the four second limiting portions prevent the four inner walls of the housing 200 from shrinking and deforming inward. Any second limiting portion can be set to be opposite to the center of the corresponding inner wall of the housing 200, so that the side wall of the housing 200 can be more fully limited by the limiting effect of the second limiting portion, thereby further reducing the degree of deformation of the housing 200 caused by the influence of the environment.

[0061] In some embodiments, reference Figure 1 As shown, the first stopper 300 of the present application and the base 100 can be an integrated structure. Specifically, the base 100 and the first stopper 300 can be integrally formed by a mold process, so that the connection effect between the base 100 and the first stopper 300 can be more stable and reliable. Specifically, the base 100 and the first stopper 300 can both be made of polymer materials, so that the base 100 and the first stopper 300 have insulation properties, and the base 100 and the first stopper 300 are integrally formed by a mold injection process.

[0062] The second stopper and the base 100 of the present application can be an integrated structure. Specifically, the base 100 and the second stopper can be integrally formed by a mold process, so that the connection effect between the base 100 and the second stopper can be more stable and reliable. Specifically, the base 100 and the second stopper can be made of polymer materials, so that the base 100 and the second stopper have insulation properties, and the base 100 and the second stopper are integrally formed by a mold injection process.

[0063] In some embodiments, reference Figure 1 , Figure 2 and Figure 6As shown, the connecting member 600 of the present application can be specifically configured to include a connecting portion 610 and an elastic snap-fit ​​portion 620, wherein the elastic snap-fit ​​portion 620 is elastically connected to the shell 200, until the connecting portion 610 is snap-fitted with the elastic snap-fit ​​portion 620, so that the connecting portion 610 can be fixed to the elastic snap-fit ​​portion 620.

[0064] The elastic buckle part 620 is arranged on the outer wall of the housing 200, one end of the elastic buckle part 620 is elastically connected to the housing 200, and the other end of the elastic buckle part 620 is separated from the housing 200, so that the other end of the elastic buckle part 620 can change the distance between it and the outer wall of the housing 200 under the action of external force. When the elastic buckle part 620 is in a natural state, the other end of the elastic buckle part 620 has a certain distance from the housing 200. A groove structure can be arranged on the surface of the elastic buckle part 620, and a convex structure that can be embedded in the groove is arranged on one side of the connecting part 610 facing the elastic buckle part 620, so that the connecting part 610 is buckled with the elastic buckle part 620 and pressed on the elastic buckle part 620, so that the other end of the elastic buckle part 620 moves relative to the housing 200, so that the elastic force of the elastic buckle part 620 and the housing 200 can react to the connecting part 610, so that the connecting part 610 and the elastic buckle part 620 can be closely abutted.

[0065] The elastic buckle part 620 and the housing 200 may be an integral structure. Specifically, the elastic buckle part 620 and the housing 200 may be integrally formed by an injection molding process, so that the elastic connection effect between the elastic buckle part 620 and the housing 200 is more stable and reliable. The connecting part 620 and the base 100 may be an integral structure. Specifically, the connecting part 610 and the base 100 may be integrally formed by an injection molding process.

[0066] In some embodiments, reference Figure 1 and Figure 2 As shown, the number of the elastic buckle parts 620 of the present application can be set to multiple, and accordingly, the number of the connecting parts 610 buckled and connected with the elastic buckle parts 620 is also multiple, and multiple connecting parts 610 are correspondingly buckled and connected with multiple elastic buckle parts 620, so that multiple connecting parts 610 are fixedly connected with multiple elastic buckle parts 620. In this way, multiple parts of the surface of the shell 200 can be fixedly connected with the base 100, so that the connection effect of the shell 200 and the base 100 is more stable and reliable.

[0067] Specifically, the number of the elastic buckle parts 620 can be set to two, and the two elastic buckle parts 620 can be arranged on the opposite sides of the housing 200 in the first direction. Correspondingly, the two connecting parts 610 corresponding to the two elastic buckle parts 620 can be located on the two sides of the base 100, and respectively opposite to the two elastic buckle parts 620. The housing 200 also has two opposite sides along the second direction, and the second direction is perpendicular to the first direction. A plurality of first limiting parts 310 can be arranged on the opposite sides of the housing 200 along the second direction, and respectively cooperate with the outer walls of the opposite sides of the housing 200 along the second direction. In this way, the outer walls of the housing 200 on the opposite sides in the first direction can be limited by the connecting member 600, and the outer walls of the housing 200 on the opposite sides in the second direction can both cooperate with the first limiting parts 310.

[0068] In some embodiments, reference Figure 3 , Figure 5 and Figure 6 As shown, the first boss 110 may be provided on the base 100 of the present application, the first boss 110 protrudes from the surface of the base 100, and the housing 200 may be sleeved on the first boss 110. Specifically, the first boss 110 may cooperate with the opening 211 of the housing 200, so that the first boss 110 passes through the opening 211 of the housing 200 to the inner cavity 221 of the housing 200. The outer side wall of the first boss 110 may fit with the inner cavity 221 of the inner cavity 221 of the housing 200, so that the housing 200 may be snap-fitted on the first boss 110. The side wall of the first boss 110 is also arranged opposite to the first limiting portion 310, so that the opposite sides of the shell 200 can respectively abut against the outer wall of the first boss 110 and the first limiting portion 310, so that the shell 200 is limited by the first boss 110 and the first limiting portion 310, so that the connection effect between the shell 200 and the base 100 is more reliable.

[0069] In some embodiments, reference Figure 3 , Figure 5 and Figure 6 As shown, the shell assembly of the present application may also be provided with a seal 500, which may be provided between the shell 200 and the first boss 110, so that the inner wall of the shell 200 and the outer wall of the first boss 110 can be sealed, thereby preventing external dirt and impurities from entering the inner cavity 221 of the shell 200 through the opening 211.

[0070] Specifically, a limiting groove 111 may be provided on the outer wall of the first boss 110, and the seal 500 may adopt a sealing collar. The seal 500 is sleeved on the first boss 110 and embedded in the limiting groove 111 of the first boss 110. The side of the seal 500 facing away from the limiting groove 111 is in contact with the inner wall of the shell 200, so that the inner wall of the shell 200 and the outer wall of the first boss 110 can be sealed.

[0071] It should be understood that when the base 100 of the present application is prepared by a mold forming process, the portion between the first limiting portion 310 and the first boss 110, and the limiting groove 111 on the first boss 110 need to be formed by a core pulling process. Since the first limiting portion 310 is opposite to the first boss 110, the first limiting portion 310 will interfere with the mold between the first limiting portion 310 and the first boss 110, so that the mold between the first limiting portion 310 and the first boss 110 cannot be pulled out in the direction toward the first limiting portion 310.

[0072] In some embodiments, in order to solve the above problems, reference is made to Figure 5 and Figure 6 As shown, when the base 100 of the present application is prepared by a mold forming process, a demoulding groove 112 may be further provided on the first boss 110 to facilitate the preparation of the base 100 by the mold forming process. The demoulding groove 112 is connected to the limiting groove 111, and the demoulding groove 112 is provided with a first notch 111a and a second notch 111b, and the first notch 111a and the second notch 111b are both connected to the demoulding groove 112, the first notch 111a is located on the top wall of the first boss 110, and the second notch 111b is located on the side wall of the first boss 110.

[0073] The demoulding groove 112 can form a first projection on the base 100 in the direction toward the base 100, and the first position-limiting portion 310 has a second orthographic projection on the base 100, wherein the first orthographic projection is opposite to the second orthographic projection. In this way, the mold between the first position-limiting portion 310 and the first boss 110 can be withdrawn through the first notch 111a in the direction away from the base 100, so that the base 100 of the present application is easier and more convenient to prepare through the mold forming process.

[0074] In some embodiments, reference Figure 3 and Figure 4 As shown, the housing 200 of the present application can be specifically configured to include a first housing 210 and a second housing 220. The first housing 210 is connected to the second housing 220, the first housing 210 is adjacent to the base 100, and the second housing 220 is away from the base 100. Specifically, the opening 211 of the housing 200 is located on the side of the first housing 210 facing away from the second housing 220, the plug interface 222 of the housing 200 is located on the side of the second housing 220 facing away from the first housing 210, the second housing 220 can be docked with the base 100, the thickness of the first housing 210 is greater than the thickness of the second housing 220, so that the contact part of the housing 200 with the base 100 has better structural strength, thereby reducing the degree of deformation of the housing 200 caused by the environment to a certain extent, so that the connection effect of the housing 200 and the base 100 is more stable and reliable.

[0075] Based on the above shell components, refer to Figure 1 , Figure 6 and Figure 7 As shown, the embodiment of the present application also proposes a connector, including an electrical connector and the above-mentioned housing assembly. A second boss 120 is further provided on the side of the base 100 facing away from the housing 200, and the first boss 110 and the second boss 120 are located on opposite sides of the housing 200. The electrical connector is provided on the base 100, and the electrical connector has a first connection end 410 and a second connection end 420, wherein the first connection end 410 is located on the first boss 110, and the second connection end 420 is located on the second boss 120. The first connection end 410 of the electrical connector can be connected to an external electrical connector through a wire passing through the plug interface 222 of the housing 200, and the second connection end 420 of the electrical connector can be connected to another external electrical connector by plugging.
