Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and in particular to a housing assembly and a switching device. Background Technology

[0002] The switching device includes a matching switch body and accessory structures. The switch body can be a circuit breaker, relay, or other switch capable of controlling the on / off state of a circuit. The accessory structures can be residual current devices (RCDs), shunt trip units, undervoltage release units, etc., and are connected to the switch body via an assembly. The accessory structures, in conjunction with the switch body, ensure that the circuit is disconnected in the event of any fault, such as leakage or short circuit, thereby reducing the possibility of further escalation of the fault.

[0003] Based on the existing assembly structure, damage to the assembly section is likely to occur during the assembly of the accessory structure and the switch body, which in turn affects the use of the switch device. Utility Model Content

[0004] This application provides a housing assembly and a switching device that can reduce or even avoid the possibility of damage to the first assembly part due to excessive deformation during the mating process of the first housing and the second housing, ensuring the reliability of the mating between the first housing and the second housing, and thus ensuring the reliability of the switching device in use.

[0005] In a first aspect, this application provides a housing assembly. The housing assembly includes a first housing, a connector, and a second housing. The first housing has a mounting groove, and a mounting hole is provided on the side wall of the first housing, the mounting hole communicating with the mounting groove. The connector is slidably mounted to the mounting groove, and a portion of the connector extends out of the mounting hole from the first housing to form a first assembly portion. Along the direction of movement of the connector, the projection of the first assembly portion is outside the projection range of the side wall, and the first assembly portion is detachably connected to the mating wall of the second housing.

[0006] In this application example, the connector is slidably mounted to the first housing, the first assembly part is part of the connector, and the first assembly part can be detachably connected to the second housing. Therefore, the first assembly part can achieve the mating of the first housing and the second housing. Compared with the prior art, where one end of the assembly part is fixed to the side wall of the first housing, and the other end of the assembly part extends towards the second housing to mate with it, during the process of connecting the first and second housings, the distance that the end of the assembly part near the second housing moves away from the first housing depends on the degree of deformation of the assembly part itself. In this application example, the first assembly part is part of the connector, and the connector is slidably mounted to the first housing. Therefore, during the assembly process of the first and second housings, the distance that the first assembly part moves away from the first housing depends on the sliding distance of the connector relative to the first housing and the degree of deformation of the first assembly part itself. This can reduce or even avoid the possibility of damage to the first assembly part due to excessive deformation, ensure the reliability of the mating between the first and second housings, and thus ensure the reliability of the switching device.

[0007] In some possible implementations, the housing assembly also includes an elastic element. The connector has a first abutment portion, and a first end of the elastic element is connected to the first abutment portion. The first housing has a second abutment portion, which is closer to the mounting hole than the first abutment portion, and a second end of the elastic element is connected to the second abutment portion.

[0008] In this example, during the assembly of the first and second housings, the connecting member, under force, moves the first abutment portion toward the outside of the first housing. Since the second abutment portion is located on the housing and is closer to the mounting hole than the first abutment portion, the distance between the first and second abutment portions decreases, and the elastic member located between the first and second housings is in a compressed state. After the force acting on the connecting member is released, the elastic member recovers its deformation, and the elastic member moves the first abutment portion away from the mounting hole within the mounting groove. The first abutment portion moves the connecting member in the direction extending into the first housing, thereby bringing the first assembly portion into contact with the mating wall of the second housing, achieving the mating of the first assembly portion and the second housing, and thus the mating of the first housing and the second housing.

[0009] Furthermore, the elastic element can apply a force away from the mounting hole to the first abutting part, thereby causing the first abutting part to have a tendency to move away from the mounting hole. In turn, the connecting element causes the first assembly part to have a force toward the second housing, making the fit between the first assembly part and the second housing tighter.

[0010] In some possible implementations, the connector has a recessed portion inside, and the first end of the elastic member abuts against the abutting wall of the recessed portion away from the mounting hole, the abutting wall being the first abutting portion. The first housing has a first abutting protrusion inside, the first abutting protrusion being closer to the mounting hole than the abutting wall, and the second end of the elastic member abuts against the first abutting protrusion, the first abutting protrusion being the second abutting portion.

[0011] In this example, the first abutting part is a recessed abutting wall, and the second abutting part is a first abutting protrusion inside the first housing. Since the recessed part is located on the connector, the connector is installed to the first housing, and the first abutting protrusion is located on the first housing, the cooperation of the elastic member, the abutting wall, and the first abutting protrusion can achieve the cooperation of the elastic member, the connector, and the first housing.

[0012] In some possible implementations, the elastic element is located on the outside of the connector, and the side wall of the connector has a second abutting protrusion. The first end of the elastic element abuts against the second abutting protrusion, which is the first abutting portion. A third abutting protrusion is provided inside the first housing. The third abutting protrusion is closer to the mounting hole than the second abutting protrusion, and the second end of the elastic element abuts against the third abutting protrusion, which is the second abutting portion.

[0013] In this application example, the first abutting part is a second abutting protrusion on the side wall of the connector, and the second abutting part is a third abutting protrusion inside the first housing. Since the second abutting protrusion is located on the connector, the connector is installed to the first housing, and the third abutting protrusion is located on the first housing, the cooperation of the elastic member, the second abutting protrusion, and the third abutting protrusion can realize the cooperation of the elastic member, the first housing, and the connector.

[0014] In some possible implementations, the first housing is provided with a mounting protrusion, a mounting groove is provided in the mounting protrusion, the end of the connector facing away from the mounting hole can extend out of the mounting groove, and the end of the connector facing away from the mounting hole is provided with a limiting protrusion, which can be engaged with the end of the mounting protrusion facing away from the mounting hole.

[0015] In this application example, the mounting groove is provided on the mounting protrusion, and the end of the connector away from the mounting hole can extend out of the mounting groove. The end of the connector away from the mounting hole is provided with a limiting protrusion. When the connector moves away from the side wall of the first housing, the limiting protrusion can be engaged with the end of the mounting protrusion away from the mounting hole to reduce or even avoid the possibility of the connector detaching from the mounting groove and ensure the assembly reliability of the connector and the first housing.

[0016] In some possible implementations, the mounting protrusion includes multiple mounting plates spaced apart, each mounting plate having a mounting slot, and the multiple mounting slots communicating and cooperating to form a mounting groove.

[0017] In this application example, the mounting protrusion includes multiple mounting plates spaced apart. Compared with setting the mounting protrusion as a single protrusion structure, the material used for the mounting protrusion can be reduced, thereby reducing the manufacturing cost of the first housing.

[0018] In some possible implementations, the connector further includes a connecting body and a connecting portion, the connecting body and the connecting portion being substantially perpendicular, the connecting body being slidably mounted to the mounting groove, one end of the connecting portion being connected to the connecting body, the other end of the connecting portion being connected to the first assembly portion, and the connecting portion obscuring at least part of the mounting hole.

[0019] In this example, the connecting part connects the first assembly part and the connecting body, and the first assembly part is connected to the mating wall of the second housing. Therefore, the first assembly part can achieve the mating of the connecting part and the second housing. Furthermore, since the connecting part is connected to the connecting body, and the connecting body can be slidably installed into the mounting groove of the first housing, the first housing and the second housing can achieve the mating of the connecting body, the connecting part, and the first assembly part.

[0020] In addition, the connection part blocks at least part of the mounting hole, which can reduce the degree of communication between the interior of the first housing and the external environment, thereby reducing or even avoiding the possibility of external dust, water and other impurities entering the interior of the first housing through the mounting hole.

[0021] In some possible implementations, the sidewall is provided with a first receiving groove, the mating wall is provided with a second receiving groove, the second receiving groove is connected to the first receiving groove, and the first receiving groove and the second receiving groove are used to accommodate at least part of the connecting part.

[0022] In this application example, the side wall of the first housing is provided with a first receiving groove, and the mating wall of the second housing is provided with a second receiving groove. The second receiving groove is connected to the first receiving groove, and the first receiving groove and the second receiving groove can accommodate at least part of the connecting part. This can reduce the size of the connecting part protruding to the side wall, thereby reducing or even avoiding the possibility of the connecting part being damaged by collision during the use of the housing assembly, and ensuring the reliability of the housing assembly.

[0023] In some possible implementations, the first assembly part is a hook structure, and the mating wall is provided with a slot structure, with the hook structure engaging with the slot structure.

[0024] In this example, the first assembly part is a hook structure, and the mating wall of the second housing is provided with a groove structure. Since the first assembly part is part of the snap-fit ​​component, the engagement between the connector and the second housing can be achieved through the snap-fit ​​between the hook structure and the groove structure. Furthermore, since the connector is installed on the first housing, the engagement between the first housing and the second housing can be achieved through the connector.

[0025] Secondly, this application provides a switching device, including the housing assembly provided in the first aspect and various possible implementations of the first aspect.

[0026] The advantages of the switching device provided in the second aspect and its various possible implementations can be seen in the advantages of the first aspect and its various possible implementations, and will not be repeated here. Attached Figure Description

[0038] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the housing assembly and switching device of this application.

[0039] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0042] To enable those skilled in the art to better understand the present application, the housing assembly and switching device provided in the present application will be clearly and completely described below with reference to the accompanying drawings.

[0043] For example, this application provides a switching device, which includes a housing assembly. The housing assembly includes a first housing and a second housing that cooperate with each other.

[0044] The switching device includes a switch body and accessory structures. The switch body can be a circuit breaker, a relay, or other switch, and the accessory structures can be residual current devices (RCDs), shunt trip units, undervoltage release units, etc., which can drive the switch body from a closed state to an open state when a circuit fault occurs. This application example only describes a circuit breaker as the switch body and an RCD as the accessory structure.

[0045] The first housing can be the housing of the switch body, and the first housing has a first receiving cavity, which can provide installation space for structural components such as the contact mechanism and the operating mechanism in the switch body. The second housing can be the housing of the accessory structure, and the second housing has a second receiving cavity, which can provide installation space for structures such as the zero-sequence current transformer and the circuit board in the accessory structure.

[0046] Alternatively, the first housing may be the housing of an accessory structure, and the second housing may be the housing of the switch body. This application example does not impose specific limitations on this.

[0047] When the circuit breaker is a two-phase circuit breaker, it includes two circuit breaker bodies. The first housing is the housing of one of the circuit breaker bodies, and the second housing is the housing of the other circuit breaker body. When the circuit breaker is a multi-phase circuit breaker, it includes multiple circuit breaker bodies. The first housing and the second housing are housings of different circuit breaker bodies, and the first housing and the second housing are arranged alternately. Adjacent sets of first housings and second housings cooperate to form housing assemblies.

[0048] For details on the specific structure of the housing assembly, please refer to the relevant description below. The example in this application will not be described in detail here.

[0049] Since the switching device provided in this application includes the housing assembly described below, the switching device provided in this application has the same effects as the housing assembly described below.

[0050] Next, the structure of the housing assembly will be described in detail.

[0051] For example, this application provides a housing assembly. Figure 1 This application provides a schematic diagram of the structure of a housing assembly. Figure 2 This application provides a schematic diagram of the structure of a connector as an example. Figure 3Please refer to the schematic diagram of a first shell provided as an example of this application. Figures 1-3 The housing assembly 100 includes a first housing 110, a connector 120, and a second housing 130. The first housing 110 has a mounting groove 111, and its side wall has a mounting hole 112 communicating with the mounting groove 111. The connector 120 is slidably mounted to the mounting groove 111. A portion of the connector extends out of the mounting hole 112 from the first housing 110 to form a first assembly portion 121. Along the direction of movement of the connector 120, the projection of the first assembly portion 121 is outside the projection range of the side wall. The first assembly portion 121 is detachably connected to the mating wall of the second housing 130.

[0052] Both the first housing 110 and the second housing 130 can be made of insulating materials, such as polyvinyl chloride, polycarbonate (also known as PC plastic), etc. The first housing 110 and the second housing 130 made of insulating materials can reduce the possibility of internal current leakage and ensure the safety of housing assembly 100 in use.

[0053] The material used to manufacture the connector 120 may be the same as that used to manufacture the first housing 110 and the second housing 130. The connector 120 may also be made of metal. This application example does not impose any specific limitations on this.

[0054] The first housing 110 has a mounting groove 111, and the connector 120 is slidably mounted to the mounting groove 111. The part of the connector that can slide in the mounting groove 111 can be cylindrical, prismatic or other columnar structures. The shape of the mounting groove 111 is adapted to the shape of the connector 120 so that the connector 120 can slide in the mounting groove 111.

[0055] The first housing 110 has a mounting hole 112 communicating with the mounting groove 111, and the shape of the mounting hole 112 is the same as that of the mounting groove 111. A portion of the connector extends out of the first housing 110 from the mounting hole 112 to form a first assembly portion 121. Along the direction of movement of the connector 120, the projection of the first assembly portion 121 is outside the projection range of the side wall, and the first assembly portion 121 is detachably connected to the mating wall of the second housing 130. That is, after the connector 120 extends out of the first housing 110 from the mounting hole 112, it extends toward the second housing 130 to form the first assembly portion 121, and the first assembly portion 121 can be connected to the mating wall of the second housing 130. The side wall of the first housing 110 and the mating wall of the second housing 130 are on the same plane in the housing assembly 100.

[0056] The first assembly part 121 can be a protruding structure, a hook structure, a hole structure, etc. Correspondingly, when the first assembly part 121 is a protruding structure, the mating wall has a groove structure, and at least part of the protruding structure can extend into the groove structure to achieve the mating of the first assembly part 121 and the second housing 130. When the first assembly part 121 is a hook structure, the mating wall has a corresponding slot structure, and the hook structure can engage with the slot structure. When the first assembly part 121 is a hole structure, the mating wall has a corresponding hole structure, and structural components such as screws, bolts, and pins can pass through the hole structure of the first assembly part 121 and the hole structure of the mating wall to achieve the connection between the first assembly part 121 and the mating wall.

[0057] The first housing 110 has sidewalls including a first sidewall and a second sidewall disposed opposite to each other, and the second housing 130 has mating walls including a first mating wall and a second mating wall disposed opposite to each other. The first mating wall and the first sidewall are in the same plane, and the second mating wall and the second sidewall are in the same plane.

[0058] One or more connectors 120 may be provided. When only one connector 120 is provided, one of the first sidewall and the second sidewall has a mounting hole 112; here, only the case where the mounting hole 112 is located on the first sidewall is described. The connector 120 can extend out of the first housing 110 through the mounting hole 112 to form a first mounting portion 121, which is detachably connected to the second housing 130. A second mounting portion is fixedly connected to the second sidewall, extending toward and detachably connecting to the second mating wall in the second housing 130.

[0059] When multiple connectors 120 are provided, they are spaced apart and located on different sidewalls of the first housing 110. Taking two connectors 120 as an example, both the first and second sidewalls are provided with mounting holes 112. Each mounting hole 112 mates with a corresponding connector 120, and the connector 120 extends out of the mounting hole 112 to form a first assembly portion 121 on the outside of the first housing 110. Specifically, the first assembly portion 121 extending out of the mounting hole 112 on the first sidewall is detachably connected to a first mating wall, and the first assembly portion 121 extending out of the mounting hole 112 on the second sidewall is detachably connected to a second mating wall. This application example only describes one connector 120.

[0060] During the assembly of the first housing 110 and the second housing 130, the first assembly part 121 moves away from the side wall of the first housing 110. Since the first assembly part 121 is part of the connector 120, the connector 120 slides in the mounting groove 111 toward the outside of the first housing 110, so that there is a gap between the first assembly part 121 and the mating wall of the second housing 130, thereby allowing the side wall of the first housing 110 and the mating wall of the second housing 130 to be on the same plane. Then, the first assembly part 121 moves toward the second housing 130 until the first assembly part 121 mates with the mating wall of the second housing 130.

[0061] In this example, the connector 120 is slidably mounted to the first housing 110, and the first assembly portion 121 is part of the connector 120. The first assembly portion 121 is detachably connected to the second housing 130, thus enabling the first housing 110 and the second housing 130 to cooperate. In contrast, in the prior art, one end of the assembly portion is fixed to the side wall of the first housing, and the other end extends towards the second housing to cooperate with it. During the process of connecting the first and second housings, the distance the end of the assembly portion near the second housing moves away from the first housing depends on the degree of deformation of the assembly portion itself. In this application example, the first assembly part 121 is part of the connector 120, and the connector 120 is slidably installed to the first housing 110. Therefore, during the assembly process of the first housing 110 and the second housing 130, the distance of the first assembly part 121 from the first housing 110 depends on the sliding distance of the connector 120 relative to the first housing 110 and the degree of deformation of the first assembly part 121 itself. This can reduce or even avoid the possibility of the first assembly part 121 being damaged due to excessive deformation, ensure the reliability of the fit between the first housing 110 and the second housing 130, and thus ensure the reliability of the switch device.

[0062] Based on the housing assembly 100 provided in the above example, Figure 4 This application provides a schematic diagram of the mating structure between a first housing and a connecting member. Figure 5 for Figure 4 Sectional view at point AA. Figure 6 for Figure 5 A magnified view of a section at point A. Please refer to the image. Figure 1 and Figures 4-6 The housing assembly 100 also includes an elastic member 140. The connector 120 is provided with a first abutment portion 124, and a first end of the elastic member 140 is connected to the first abutment portion 124. The first housing 110 is provided with a second abutment portion 113, which is closer to the mounting hole 112 than the first abutment portion 124, and a second end of the elastic member 140 is connected to the second abutment portion 113.

[0063] The elastic element 140 can be a sheet, spring, or other structure. This application example only describes the elastic element 140 as a spring. The elastic element 140 can be installed inside the connector 120 or outside the connector 120.

[0064] The first abutment 124 can be a protrusion on the connector 120 or another elastic member 140 that can abut against it. Multiple first abutment portions 124 can be spaced apart, or there can be only one. The second abutment 113 is a protrusion inside the first housing 110. For example, the second abutment 113 can be located on the wall of the mounting groove 111. The second abutment 113 can also be the inner wall of the first housing 110 where the mounting hole 112 is located. This application example does not limit the specific structure of the first abutment 124 and the second abutment 113.

[0065] During the assembly process of the first housing 110 and the second housing 130, the first assembly part 121 moves away from the first housing 110 under force. Since the first assembly part 121 is part of the connector 120, the connector 120 moves in the direction extending out of the first housing 110. The first abutment part 124 of the connector 120 moves in the direction extending out of the first housing 110. Since the connector 120 extends out of the first housing 110 from the mounting hole 112, and the second abutment part 113 is located closer to the mounting hole 112 than the first abutment part 124, the distance between the first abutment part 124 and the second abutment part 113 decreases compared to when the connector 120 is in the initial position, and the elastic member 140 is in a compressed state. During the process of the first assembly part 121 cooperating with the second housing 130, the force acting on the first assembly part 121 that causes the first assembly part 121 to move away from the first housing 110 is released, the elastic member 140 restores its deformation, and under the action of the elastic member 140, the first abutting part 124 moves away from the mounting hole 112. Since the first abutting part 124 is provided on the connector 120, the connector 120 moves in the direction of extending into the first housing 110, thereby making the first assembly part 121 cooperate with the mating wall of the second housing 130.

[0066] The initial position of the connector 120 refers to the position of the connector 120 when the first assembly part 121 is not under force. At this time, the elastic member 140 can be in a free state or in a compressed state.

[0067] In this application example, during the assembly process of the first housing 110 and the second housing 130, the connector 120 is driven by force to move the first abutment 124 toward the outside of the first housing 110. Since the second abutment 113 is provided on the housing and is located closer to the mounting hole 112 than the first abutment 124, the distance between the first abutment 124 and the second abutment 113 becomes smaller, and the elastic member 140 provided between the first housing 110 and the second housing 130 is in a compressed state. After the force acting on the connector 120 is released, the elastic member 140 restores its deformation, causing the first abutment part 124 to move away from the mounting hole 112 in the mounting groove 111. The first abutment part 124 causes the connector 120 to move in the direction of extending into the first housing 110, thereby making the first assembly part 121 contact the mating wall of the second housing 130, realizing the mating of the first assembly part 121 and the second housing 130, and thus realizing the mating of the first housing 110 and the second housing 130.

[0068] Furthermore, the elastic member 140 can apply a force away from the mounting hole 112 to the first abutting part 124, thereby causing the first abutting part 124 to have a tendency to move away from the mounting hole 112. In turn, the connecting member 120 causes the first assembly part 121 to have a force toward the second housing 130, making the fit between the first assembly part 121 and the second housing 130 tighter.

[0069] The first abutment portion 124 and the second abutment portion 113 are implemented differently depending on the location where the elastic member 140 is connected to the connector 120. The specific implementations of the first abutment portion 124 and the second abutment portion 113 will be described by way of example below.

[0070] For example, please refer to Figure 5 and Figure 6 When the elastic member 140 is installed inside the connector 120, the connector 120 has a recess 125 inside. The first end of the elastic member 140 abuts against the abutment wall 1251 of the recess 125 away from the mounting hole 112. The abutment wall 1251 is the first abutment part 124. The first housing 110 has a first abutment protrusion inside. The first abutment protrusion is positioned closer to the mounting hole 112 than the abutment wall 1251. The second end of the elastic member 140 abuts against the first abutment protrusion. The first abutment protrusion is the second abutment part 113.

[0071] The recess 125 can be a blind hole, a groove, or other recessed structure. The abutment wall 1251 is the wall of the recess 125 away from the mounting hole 112. The recess 125 can also be a through hole, in which case the hole wall of the through hole is provided with a protruding structure, and the first end of the elastic member 140 can abut against the protruding structure, which is the first abutment 124.

[0072] The first abutting protrusion can be located on the groove wall of the mounting groove 111 or inside the first housing 110, as long as the first abutting protrusion is located closer to the mounting hole 112 than the abutting wall 1251, and the second end of the elastic member 140 can be connected to the first abutting protrusion.

[0073] The recess 125 is located inside the connector 120, and the first abutting protrusion is located in the first housing 110. Therefore, as the connector 120 slides in the mounting groove 111, the distance between the abutting wall 1251 of the recess 125 and the first abutting protrusion changes, thereby changing the state of the elastic member 140 and adjusting the fit between the first assembly part 121 and the second housing 130.

[0074] In this application example, the first abutting portion 124 is set as the abutting wall 1251 of the recessed portion 125, and the second abutting portion 113 is the first abutting protrusion inside the first housing 110. Since the recessed portion 125 is provided on the connector 120, the connector 120 is installed to the first housing 110, and the first abutting protrusion is provided on the first housing 110, the elastic member 140, the connector 120, and the first abutting protrusion can cooperate to achieve the engagement of the elastic member 140, the connector 120, and the first housing 110.

[0075] For example, when the elastic member 140 is located outside the connector 120, the side wall of the connector 120 is provided with a second abutting protrusion, and the first end of the elastic member 140 abuts against the second abutting protrusion, which is the first abutting portion. The first housing 110 is provided with a third abutting protrusion, which is located closer to the mounting hole 112 than the second abutting protrusion, and the second end of the elastic member 140 abuts against the third abutting protrusion, which is the second abutting portion.

[0076] When the elastic element 140 is a spring, the spring can be sleeved on the outside of the connector 120. The second abutting protrusion can be a protrusion structure provided on the side wall of the connector 120. Multiple second abutting protrusions can be provided at intervals, or there can be only one second abutting protrusion.

[0077] The third abutting protrusion can be a protrusion structure set on the wall of the mounting groove 111, or it can be a protrusion structure set inside the first housing 110. As long as the third abutting protrusion is set closer to the mounting hole 112 than the second abutting protrusion, and the second end of the elastic member 140 can be connected to the third abutting protrusion.

[0078] Since the second abutting protrusion is located on the outside of the connector 120 and the third abutting protrusion is located on the first housing 110, as the connector 120 slides in the mounting groove 111, the distance between the second abutting protrusion and the third abutting protrusion changes, thereby changing the state of the elastic member 140, and the fitting relationship between the first assembly part 121 and the second housing 130 can be adjusted.

[0079] In this example, the first abutting portion 124 is a second abutting protrusion on the side wall of the connector 120, and the second abutting portion 113 is a third abutting protrusion inside the first housing 110. Since the second abutting protrusion is located on the connector 120, the connector 120 is installed to the first housing 110, and the third abutting protrusion is located on the first housing 110, the engagement of the elastic member 140, the connector 120, and the first housing 110 can be achieved through the cooperation of the elastic member 140, the second abutting protrusion, and the third abutting protrusion.

[0080] Based on the housing assembly 100 provided in the above example, please refer to Figure 3 , Figure 5 and Figure 6 The first housing 110 is provided with a mounting protrusion 114 and a mounting groove 111 is provided in the mounting protrusion 114. The end of the connector 120 facing away from the mounting hole 112 can extend into the mounting groove 111, and the end of the connector 120 facing away from the mounting hole 112 is provided with a limiting protrusion 126, which can be engaged with the end of the mounting protrusion 114 facing away from the mounting hole 112.

[0081] There may be only one mounting protrusion 114, or there may be multiple mounting protrusions 114 spaced apart. The mounting protrusion 114 may be a prismatic structure, a plate-like structure, etc. The limiting protrusion 126 is provided on the side wall of the connector 120 opposite to the mounting hole 112. There may be multiple limiting protrusions 126 spaced apart, or there may be only one limiting protrusion 126.

[0082] In this application example, the mounting groove 111 is provided on the mounting protrusion 114, and the end of the connector 120 facing away from the mounting hole 112 can extend out of the mounting groove 111. The end of the connector 120 facing away from the mounting hole 112 is provided with a limiting protrusion 126. When the connector 120 moves away from the side wall of the first housing 110, the limiting protrusion 126 can be engaged with the end of the mounting protrusion 114 facing away from the mounting hole 112, so as to reduce or even avoid the possibility of the connector 120 disengaging from the mounting groove 111 and ensure the assembly reliability of the connector 120 and the first housing 110.

[0083] Based on the housing assembly 100 provided in the above example, please refer to Figure 3The mounting protrusion 114 includes a plurality of mounting plates 1141 spaced apart, each mounting plate 1141 having a mounting groove 1111, and the plurality of mounting grooves 1111 cooperate to form a mounting groove 111.

[0084] Mounting plates 1141 may have two, three, or other spacings. Each mounting slot 1111 has the same shape, and the shape of the mounting slot 1111 is adapted to the shape of the connector 120.

[0085] In this application example, the mounting protrusion 114 includes multiple mounting plates 1141 spaced apart. Compared with setting the mounting protrusion 114 as a whole protrusion structure, the material used for the mounting protrusion 114 can be reduced, thereby reducing the manufacturing cost of the first housing 110.

[0086] Based on the housing assembly 100 provided in the above example, please refer to Figure 2 The connector 120 also includes a connecting body 123 and a connecting part 122. The connecting body 123 and the connecting part 122 are substantially perpendicular. The connecting body 123 is slidably installed into the mounting groove 111. One end of the connecting part 122 is connected to the connecting body 123, and the other end of the connecting part 122 is connected to the first assembly part 121. The connecting part 122 covers at least part of the mounting hole 112.

[0087] The connecting body 123 can be slidably installed into the mounting groove 111. The connecting body 123 can be cylindrical, prismatic, or other columnar structures.

[0088] The connection body 123 and the connection part 122 are basically perpendicular. This can be understood as the angle formed by the connection body 123 and the connection part 122 being greater than or equal to 85° and less than or equal to 95°. Here, the connection body 123 and the connection part 122 being basically perpendicular means that when the connector 120 is not under force, the connection body 123 and the connection part 122 are basically perpendicular.

[0089] The connecting portion 122 moves relative to the mounting hole 112 as the connecting body 123 slides within the mounting groove 111. One end of the connecting portion 122 is connected to the first assembly portion 121, and when the first assembly portion 121 engages with the mating wall of the second housing 130, the connecting portion 122 obstructs at least a portion of the mounting hole 112.

[0090] In this example, the connecting part 122 is connected to the first assembly part 121, and the first assembly part 121 is connected to the mating wall of the second housing 130. Therefore, the first assembly part 121 can be used to achieve the mating of the connecting part 122 and the second housing 130. Furthermore, since the connecting part 122 is connected to the connecting body 123, and the connecting body 123 is slidably installed into the mounting groove 111 of the first housing 110, the connecting body 123, the connecting part 122, and the first assembly part 121 can be used to achieve the mating of the first housing 110 and the second housing 130.

[0091] In addition, the connecting part 122 blocks at least part of the mounting hole 112, which can reduce the degree of communication between the interior of the first housing 110 and the external environment, thereby reducing or even preventing the possibility of external dust, water and other impurities entering the interior of the first housing 110 through the mounting hole 112.

[0092] Based on the housing assembly 100 provided in the above example, please refer to Figures 1-3 The side wall is provided with a first receiving groove, and the mating wall is provided with a second receiving groove. The second receiving groove is connected to the first receiving groove. The first receiving groove and the second receiving groove are used to accommodate at least part of the connecting part 122.

[0093] The first receiving groove communicates with the mounting hole 112 and is located on the side of the mounting hole 112 facing closer to the second housing 130. Along the direction of movement of the connector 120, the depth of the first receiving groove may be equal to or unequal to the thickness of the connecting portion 122.

[0094] The second receiving groove is connected to the first receiving groove, so that the first receiving groove and the second receiving groove can cooperate to accommodate the connecting part 122. The first assembly part 121 connected to the connecting part 122 can extend into the second receiving groove and be detachably connected to the mating wall.

[0095] In this application example, the side wall of the first housing 110 is provided with a first receiving groove, and the mating wall of the second housing 130 is provided with a second receiving groove. The second receiving groove is connected to the first receiving groove, and the first receiving groove and the second receiving groove can accommodate at least part of the connecting part 122. This can reduce the size of the connecting part 122 protruding to the side wall, thereby reducing or even avoiding the possibility of the connecting part 122 being damaged by collision during the use of the housing assembly 100, and ensuring the reliability of the housing assembly 100.

[0096] Based on the housing assembly 100 provided in the above example, please refer to Figure 1 and Figure 2 The first assembly part 121 is a hook structure, and the second housing 130 is provided with a slot structure, and the hook structure and the slot structure are engaged.

[0097] In this example, the first assembly part 121 is configured as a hook structure, and the mating wall of the second housing 130 is provided with a slot structure. Since the first assembly part 121 is part of the snap-fit ​​component, the engagement between the connector 120 and the second housing 130 can be achieved through the snap-fit ​​between the hook structure and the slot structure. Furthermore, since the connector 120 is installed to the first housing 110, the engagement between the first housing 110 and the second housing 130 can be achieved through the connector 120.

[0098] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
