Description

Technical Field

[0001] This utility model relates to the field of high voltage electronic connector technology, and in particular to an integrated board-end connector and module housing integrated structure. Background Technology

[0002] With the rapid development of the new energy vehicle industry and the precision upgrade of high-end equipment manufacturing, the integration requirements of core components in the high-voltage systems of vehicles and equipment have significantly increased. As a key component connecting electronic modules and wiring harnesses, the board-end connector's structure directly affects the module's space utilization, assembly efficiency, and electromagnetic compatibility. Currently, the connection between the board-end connector and the module housing in the industry mostly adopts a separate design: that is, the board-end connector is manufactured as an independent component and subsequently fixed to the module housing through secondary assembly methods such as bolts and clips. For example, patent CN106374282A discloses a high-voltage shielded electrical connector assembly that is easy to install. This assembly, through the design of the housing, transition contact assembly, and shielding layers I and II, achieves all-round shielding and a 90° bend-free transition from the shielded wire to the board-end connector. However, this structure still has the following significant drawbacks: High space occupancy: The split design requires additional installation space for the connection between the board-end connector and the module housing, and the independent connector housing increases the overall structural size, making it difficult to meet the development needs of miniaturization and high-density layout of electronic modules. The assembly process is complicated: The assembly process requires additional investment in fasteners and assembly time, which not only increases material costs and production cycle, but also increases the risk of assembly errors due to multiple assembly processes. Poor electromagnetic shielding continuity: The connection interface of the split structure (the mating point between the board connector and the module housing) is prone to electromagnetic leakage weak points. Even if the board connector itself has shielding function, the gap and assembly tolerance of the connection interface can still lead to the intrusion or leakage of electromagnetic interference, which in turn affects the quality of the CAN signal inside the module and may even cause operational safety problems of the whole vehicle or equipment. This problem is more prominent, especially in high voltage and high current scenarios. Utility Model Content

[0003] This utility model proposes an integrated board-end connector and module housing structure, which solves the problems of high space occupancy, cumbersome assembly process and poor electromagnetic shielding continuity caused by the separate design of board-end connector and module housing in the prior art.

[0004] The technical solution of this utility model is implemented as follows: An integrated board-end connector and module housing structure includes a shielding layer, a module housing, and an inner core assembly. The module housing comprises a housing body and a groove structure. The groove structure is embedded within the housing body and is located on the outer side of the shielding layer. The inner core assembly for electrical connection is located on the inner side of the shielding layer. During connector use, the shielding layer simultaneously contacts the groove structure and the mating end of the connector to form an electromagnetic shielding path. The module housing, as the integrated housing of the board-end connector, is integrally mounted on the module structure, effectively reducing the number of independent components, simplifying the assembly process, and thus significantly reducing material and assembly costs. The shielding layer simultaneously contacts the groove structure and the mating end of the connector, ensuring the continuity of electromagnetic shielding and solving the problem of poor electromagnetic shielding performance at the mating point between the board-end connector and the module housing.

[0005] The lower part of the shielding layer is engaged with the groove structure, and the upper part of the shielding layer is engaged with the inner core assembly. The shielding layer is used to fix the inner core assembly, realizing the mechanical connection between the inner core assembly and the module housing, and ensuring the installation stability of the inner core assembly.

[0006] The inner side of the groove structure is provided with an annular hanging groove, and the lower part of the shielding layer is provided with a lower hanging structure. The lower hanging structure is located on the outer side of the shielding layer and is arranged obliquely upward. The lower hanging structure is engaged with the upper side wall of the annular hanging groove. Through the cooperation between the lower hanging structure and the annular hanging groove, the shielding layer is limited and fixed on the groove structure, ensuring the stable installation of the shielding layer on the module housing.

[0007] The groove structure has a guide groove at its upper opening. The guide groove is an inclined groove and corresponds to the lower hanging structure on the shielding layer. When the shielding layer is inserted into the groove structure, the lower hanging structure needs to be pressed to allow it to pass over the inner wall of the groove and enter the annular hanging groove. The guide groove reduces the force required for the shielding layer to enter the groove structure, facilitating the assembly of the shielding layer on the groove structure.

[0008] The lower part of the shielding layer is provided with a lower elastic cantilever, which is located on the outside of the shielding layer and is arranged obliquely upward. The lower elastic cantilever contacts the inner wall of the groove structure. After the shielding layer is installed in place, the lower elastic cantilever contacts the inner wall of the groove, establishing an electromagnetic shielding path.

[0009] The inner core assembly is provided with a mounting step, and the upper part of the shielding layer is provided with an upper mounting structure. The upper mounting structure is located on the inner side of the shielding layer and is arranged diagonally downward. The upper mounting structure engages with the mounting step. Through the cooperation of the upper mounting structure and the mounting step, the inner core assembly is limited and fixed inside the shielding layer, ensuring the stable installation of the inner core assembly within the module housing.

[0010] The upper part of the shielding layer is provided with an upper elastic cantilever, which is located on the outside of the shielding layer and is arranged diagonally downward. The upper elastic cantilever contacts the mating end of the connector. After the connector is mated, the upper elastic cantilever contacts the mating end, forming an electromagnetic shielding path.

[0011] The outer side of the groove structure is provided with a protrusion or annular plate. After the groove structure is embedded into the shell body, the protrusion or annular plate plays an axial limiting role for the groove structure, thereby ensuring the installation stability of the groove structure within the shell body.

[0012] An electrical connection portion is located in the middle of the main housing body, and an electrical connector is located within the inner core assembly. The electrical connection portion is connected to the electrical connector. The electrical connection between the electrical connection portion and the terminal ensures the electrical signal transmission function of the connector base.

[0013] The lower part of the shielding layer has positioning protrusions facing inwards, which mate with the module housing. The positioning protrusions radially limit the shielding layer, ensuring accurate installation of the shielding layer within the module housing.

[0014] The beneficial effects of this utility model are: by integrating the shell of the board-end connector with the module shell to form an integrated board-end connector structure, the overall structural size is reduced, providing key support for the miniaturization and high-density layout of the connector and even the entire electronic module; and it effectively reduces the number of independent parts, simplifies the assembly process, thereby significantly reducing material costs and assembly costs.

[0015] When the connector is connected to the mating end, the shielding layer simultaneously contacts the groove structure and the mating end of the connector, ensuring the continuity of electromagnetic shielding and solving the problem of poor electromagnetic shielding performance at the mating point between the board-end connector and the module housing.

[0016] The shielding layer is fixed to the module housing and the inner core assembly is fixed inside the module housing by using the hanging structure on the shielding layer, which effectively simplifies the assembly process and improves assembly efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, an integrated board-end connector and module housing structure includes a shielding layer 1, a module housing 2, and an inner core assembly 3. The module housing 2 includes a housing body 22 and a groove structure 21. The groove structure 21 is embedded in the housing body 22 and is located on the outer side of the shielding layer 1. The inner core assembly 3 for electrical connection is located on the inner side of the shielding layer 1. When the connector is in use, the shielding layer 1 simultaneously contacts the groove structure 21 and the mating end of the connector to form an electromagnetic shielding path. Integrating the board-end connector housing and the module housing 2 into a single structure reduces the overall structural size and provides key support for the miniaturization and high-density layout of the connector and even the entire electronic module. Furthermore, it effectively reduces the number of independent components, simplifies the assembly process, and thus significantly reduces material and assembly costs.

[0022] In addition, the shielding layer 1 and the groove structure 21 are made of metal, while the housing body 22 is made of plastic. The housing body 22 is formed by injection molding, and the groove structure 21 is embedded into the housing body 22 by injection molding. When the board-end connector on the module is connected to the mating end, the shielding layer 1 simultaneously contacts the groove structure 21 and the mating end of the connector, establishing a continuous electromagnetic shielding path, ensuring the continuity of electromagnetic shielding, and solving the problem of poor electromagnetic shielding performance at the mating point between the board-end connector and the module housing 2.

[0023] Furthermore, such as Figure 3 As shown, the lower part of the shielding layer 1 is engaged with the groove structure 21, and the upper part of the shielding layer 1 is engaged with the inner core assembly 3. The inner core assembly 3 is installed into the module housing 2 through the shielding layer 1. The shielding layer 1 effectively limits the inner core assembly 3, ensuring the installation stability of the inner core assembly 3 within the module housing 2.

[0024] Example 2 differs from Example 1 in that it is an integrated board-end connector and module housing integrated structure. In this example, when the shielding layer 1 is connected to the module housing 2, the housing body 22 is located outside the shielding layer 1, and the groove structure 21 is located inside the shielding layer 1. At this time, the outer side of the groove structure 21 is attached to the shielding layer 1.

[0025] Example 3, based on Example 1, provides an integrated board-end connector and module housing structure, such as... Figure 4 , Figure 5 As shown, the inner side of the groove structure 21 is provided with an annular hook groove 211, and the lower part of the shielding layer 1 is provided with a lower hook structure 14. The lower hook structure 14 is located on the outer side of the shielding layer 1 and is arranged obliquely upward. The lower hook structure 14 is hooked and cooperates with the upper side wall of the annular hook groove 211. The lower hook structure 14 is a spring piece structure. In this embodiment, the shielding layer 1 is made by sheet metal stamping and bending. The shielding layer 1 is a rectangular structure. After the shielding layer 1 is installed, the end of the spring piece structure cooperates with the upper side wall of the annular hook groove 211, and the lower end face of the shielding layer 1 cooperates with the step inside the module housing 2 to achieve axial positioning of the shielding layer 1 inside the module housing 1.

[0026] Furthermore, such as Figure 4 As shown, a guide groove 213 is provided at the upper opening of the groove structure 21. The guide groove 213 is an inclined groove, and the guide groove 213 corresponds to the position of the lower hanging structure 14 on the shielding layer 1. When the shielding layer 1 is inserted downward into the groove structure 21, the lower hanging structure 14 needs to be pressed so that the lower hanging structure 14 passes over the inner wall 212 of the groove and enters the annular hanging groove 211. The guide groove 213 can reduce the force required for the shielding layer 1 to enter the groove structure 21, which facilitates the assembly of the shielding layer 1 on the groove structure 21.

[0027] Furthermore, such as Figure 3 , Figure 6 As shown, a lower elastic cantilever 13 is provided at the lower part of the shielding layer 1. The lower elastic cantilever 13 is located on the outside of the shielding layer 1 and is arranged obliquely upward. The lower elastic cantilever 13 contacts the inner wall 212 of the groove structure 21. After the shielding layer 1 is installed in place, the lower elastic cantilever 13 contacts the inner wall 212 of the groove, establishing an electromagnetic shielding path.

[0028] Furthermore, such as Figure 5 , Figure 7 As shown, the inner core assembly 3 is provided with a mounting step 31, and the upper part of the shielding layer 1 is provided with an upper mounting structure 11. The upper mounting structure 11 is located on the inner side of the shielding layer 1 and is arranged obliquely downward. The upper mounting structure 11 is engaged with the mounting step 31. The upper mounting structure 11 is a spring-loaded structure. After the shielding layer 1 is installed, the end of the spring-loaded structure engages with the mounting step 31, and the lower end face of the inner core assembly 3 contacts the step inside the module housing 2, realizing the axial positioning of the inner core assembly 3 inside the module housing 2. By utilizing the elasticity of the shielding layer 1 itself, a stable mechanical interlock is achieved, ensuring the installation stability of the inner core assembly 3 inside the module housing 2.

[0029] Furthermore, an upper elastic cantilever 12 is provided on the upper part of the shielding layer 1. The upper elastic cantilever 12 is located on the outside of the shielding layer 1 and is arranged obliquely downward. The upper elastic cantilever 12 contacts the mating end of the connector. After the connector is mated, the upper elastic cantilever 11 contacts the mating end, forming an electromagnetic shielding path.

[0030] The assembly process is as follows: First, the groove structure 21 is embedded in the shell body 22. Then, the shielding layer 1 is inserted downward into the groove structure 21, so that the lower hanging structure 14 on the shielding layer 1 cooperates with the annular hanging groove 211. At this time, the shielding layer 1 is fixed in the module shell 2. Finally, the inner core assembly 3 is inserted downward into the inner side of the shielding layer 1, so that the upper hanging structure 11 on the shielding layer 1 cooperates with the hanging step 31. At this time, the inner core assembly 3 is fixed in the inner side of the shielding layer 1, thereby fixing the inner core assembly 3 in the module shell 2.

[0031] Example 4 differs from Example 3 in that it is an integrated board-end connector and module housing integrated structure. In this example, the side wall of the groove structure 21 has a hanging point, and the lower part of the shielding layer 1 is provided with a hanging hole. After the shielding layer 1 is inserted into the module housing 2, the hanging hole and the hanging point cooperate, and the lower end face of the shielding layer 1 cooperates with the step inside the module housing 2 to achieve axial positioning of the shielding layer 1 inside the module housing 1.

[0032] Example 5, based on Example 1, provides an integrated board-end connector and module housing structure, wherein the outer side of the groove structure 21 is provided with a protrusion or annular plate. In this example, the outer side of the groove structure 21 is provided with an annular plate. After the groove structure 21 is embedded in the housing body 22, the annular plate axially limits the groove structure 21, thereby ensuring the installation stability of the groove structure 21 within the housing body 22.

[0033] Furthermore, such as Figure 6 As shown, an electrical connection portion 221 is provided in the middle of the housing body 22, and an electrical connector is provided in the inner core assembly 3. The electrical connection portion 221 is connected to the electrical connector. In this embodiment, the electrical connector is a terminal, and the electrical connection portion 221 is a conductive terminal inside the module. The terminal is connected to the conductive terminal to realize the electrical connection, thereby realizing the electrical signal transmission function of the board-end connector.

[0034] Furthermore, the lower part of the shielding layer 1 is provided with positioning protrusions 15 facing the inside of the shielding layer 1, and the positioning protrusions 15 cooperate with the module housing 2. Specifically, the positioning protrusions 15 cooperate with the housing body 22; the positioning protrusions 15 radially limit the shielding layer 1 to ensure that the shielding layer 1 is accurately installed in the housing body 22.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
