Description

Technical Field

[0001] The present invention relates to the technical field of automobile accessories, and in particular to an electromagnetic shielding structure, a male and female connector, and a shielding system. Background Art

[0002] PDU (Power Distribution Unit), also known as high-voltage distribution box. In the high-voltage system solution of new energy vehicles, the high-voltage power distribution unit mainly plays the role of the uniformity and reliability of the connection and shielding of the EMC structure. PDU electrically connects high-voltage components through busbars and wiring harnesses, and provides functions such as charge and discharge control, power-on control of high-voltage components, circuit overload and short-circuit protection, high-voltage sampling, and low-voltage control for the high-voltage system of new energy vehicles, protecting and monitoring the operation of the high-voltage system.

[0003] In the existing design, in order to prevent the high voltage of the main body from generating external electromagnetic interference; at the same time, it can also prevent the external electromagnetic interference from contacting the plug-in terminal, so it is often necessary to set a shielding structure; the shielding structure usually needs to be installed between the male and female terminals. For example, in the Chinese patent document CN207183627U, the front shielding spring is clamped in the ring groove of the plug body, and is pressed in the ring groove through an auxiliary sealing ring, so that the auxiliary sealing ring serves the purpose of limiting the shielding spring. Therefore, in actual installation and use, it is necessary to set a mounting groove on the mounting end face separately, and a separate limiting structure is required during the installation process to enable plug-in. Therefore, in actual use, the installation and disassembly of the shielding structure is more complicated, resulting in more complicated use; at the same time, the limiting structure set above is also prone to aging. At the same time, with the increase in the number of plug-ins, the installation between the shielding structure and the terminal will not be tight, and it is easy to move out along the mounting groove, resulting in the problem of low structural stability. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is that the shielding structure in the prior art is relatively complicated to install and disassemble, resulting in complicated use; at the same time, the limiting structure provided in conjunction with the shielding structure is also prone to aging. At the same time, as the number of plug-in times increases, the installation between the shielding structure and the terminal will not be tight, and the shielding structure is easy to move out along the installation groove, resulting in the defect of low structural stability.

[0016] It also includes at least one electromagnetic shielding structure, wherein the male end shell is the outer shell of the male end, and the female end shell is the outer shell of the female end; the electromagnetic shielding structure is detachably enclosed and installed on the outer peripheral surface of the end of the female end shell, and the end is an end that is mated and plugged with the male end shell.

[0017] Optionally, in the male and female connectors, at least two paving grooves are provided on the end of the female housing on the mating side with the male housing, and are recessed inwardly along the male plugging direction, and the paving grooves are provided in cooperation with the raised portion of the male end;

[0018] Two electromagnetic shielding structures are provided, and any one of the electromagnetic shielding structures is installed between two adjacent give-way slots.

[0022] The technical solution provided by the present invention has the following advantages:

[0023] 1. The electromagnetic shielding structure provided by the present invention is detachably installed between the male end shell and the female end shell, and comprises: a mounting body, a swivel mounting portion, and a plurality of first elastic pieces. The mounting body is installed in the female end shell, and the mounting body has a limited plug-in end that is limitedly inserted into the first mounting structure in the female end shell; one end of the swivel mounting portion is connected to the mounting body, and the other end is swivel outward along the edge of the female end shell and installed on the second mounting structure outside the female end shell; one end of the first elastic piece is installed on the mounting body, and the other end of the first elastic piece is elastically connected to the male end shell.

[0024] In the electromagnetic shielding structure of this structure, the first mounting structure and the second mounting structure on the female end shell are interconnected with the limit plug-in end and the rotating mounting part, so that the electromagnetic shielding structure and the inner and outer sides of the female end shell can be limited, and when either side of the electromagnetic shielding structure is subjected to force during the plugging and unplugging of the male and female terminals, the electromagnetic shielding structure will not be displaced; at the same time, the electromagnetic shielding structure does not require other structures to limit it separately, but is directly assembled with the female end shell through its own limiting part, ensuring that the male and female ends will not be displaced due to external force during installation and disassembly; thereby, while improving the installation reliability of the electromagnetic shielding structure, there is no need to set up other limiting mounting structures separately, ensuring that the disassembly and assembly of the shielding structure is simple and convenient.

[0025] 2. In the electromagnetic shielding structure provided by the present invention, the first mounting structure is a limiting mounting groove, and the limiting plug-in end is inserted into the limiting mounting groove; the limiting mounting groove has at least one first limiting wall, and the limiting plug-in end abuts against the first limiting wall to limit the mounting body from flipping out of the female end shell.

[0026] The electromagnetic shielding structure of this structure is provided with a limit installation groove, so that when the male and female terminals are in the process of plugging and unplugging, the electromagnetic shielding structure is subjected to a force along the plugging and unplugging direction of the male end. At the same time, since the first spring piece portion is connected to the male end shell, there is also a force in the force direction of the electromagnetic shielding structure that drives the electromagnetic shielding structure as a whole to reverse. Therefore, the first limit wall and the outer wall surface of the limit plug-in end abut against each other, thereby suppressing the action of the male and female ends driving the electromagnetic shielding structure to reverse during the plugging and unplugging process, thereby further ensuring the stability of the installation of the electromagnetic shielding structure during the plugging and unplugging process of the male and female ends.

[0027] 3. In the electromagnetic shielding structure provided by the present invention, the position-limiting plug-in end is the end of the installation body close to the female end housing; the position-limiting installation groove is extended along the insertion direction parallel to the male end housing. The position-limiting installation groove is extended along the insertion direction perpendicular to the male end housing, and the position-limiting plug-in end is a position-limiting protrusion protruding perpendicular to the insertion direction, and the position-limiting protrusion abuts against the inner wall of the position-limiting installation groove to limit the installation body from being separated from the female end housing.

[0028] In the electromagnetic shielding structure of this structure, the setting position of the first mounting structure of different female end shells is matched with the limiting plug-in end of different electromagnetic shielding structures, which is convenient for users to set different first mounting structures according to the specific use environment, thereby improving the adaptability of the electromagnetic shielding structure.

[0029] 4. In the electromagnetic shielding structure provided by the present invention, the second mounting structure has a limiting protrusion protruding outwardly along the outer wall surface; the rotary mounting portion is provided with a mounting hole, and the mounting hole is buckled with the limiting protrusion.

[0030] In the electromagnetic shielding structure of this structure, during the plugging and unplugging process of the male and female terminals, the rotating mounting part in the electromagnetic shielding structure not only ensures the stability of the installation by abutting against the outer wall surface of the female end shell, but also ensures the stability of the installation of the electromagnetic shielding structure through the limiting effect of the relief protrusion and the mounting hole, thereby further ensuring the reliability of the installation.

[0031] 5. The male and female connector provided by the present invention includes a male end and a female end, and has an outer shell, and the male end is plugged into the female end; it also includes at least one electromagnetic shielding structure, the male end shell is the outer shell of the male end, and the female end shell is the outer shell of the female end; the electromagnetic shielding structure is detachably enclosed and installed on the outer peripheral surface of the end of the female end shell, and the end is an end that cooperates with the male end shell.

[0032] The male and female connectors of this structure are installed in a ring shape on the outer periphery of the female housing through an electromagnetic shielding structure, so that the electromagnetic shielding structure forms an electromagnetic shielding layer. The electromagnetic shielding layer blocks the electromagnetic waves generated by the male and female terminals during the plug-in process from radiating to the outside of the terminal housing. In addition, the electromagnetic radiation outside the housing is also blocked to prevent external radiation from interfering with the internal connectors, thereby ensuring the electromagnetic stability of the male and female connectors.

[0033] 6. The male and female connector provided by the present invention has at least two clearance grooves recessed inwardly along the male end plug-in direction on the end portion of the female end shell and the male end shell, and the clearance grooves are arranged in cooperation with the raised portion of the male end; two electromagnetic shielding structures are provided, and any one of the electromagnetic shielding structures is installed between two adjacent clearance grooves.

[0034] In the male and female connectors of this structure, the clearance grooves and the raised parts are arranged in cooperation to ensure the installation stability of the male and female terminals; the electromagnetic shielding structure is installed at intervals between adjacent clearance grooves. While ensuring the installation stability of the male and female terminals, the installation of the electromagnetic shielding structure further ensures the shielding effect of the male and female connectors on internal and external radiation, thereby improving the stability of the shielding.

[0035] 7. The shielding system provided by the present invention comprises a male and female connector, and an auxiliary shielding structure, which is arranged in the cable connection side of the female housing, the auxiliary shielding structure is arranged in cooperation with the female cable, and the auxiliary shielding structure also comprises a limiting abutment portion, the limiting abutment portion abuts against one end of the cable close to the female housing. .

[0036] The setting of the above-mentioned auxiliary shielding effect connects the cable shielding layer with the metal shell of the female end, thereby forming a complete connector shielding system together with the aforementioned electromagnetic shielding structure, further ensuring the internal and external radiation shielding effect of the male and female end connections and the high-voltage distribution box as a whole, and improving the stability of the shielding.

[0052] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Example 1

[0054] This embodiment provides a shielding system, such as Figures 1 to 4 As shown, it includes: a male and female end connector, and an auxiliary shielding structure 4. Specifically, the male and female end connector includes a male end, a female end, and an electromagnetic shielding structure 1.

[0055] Among them, both the male and female ends have an outer shell, the male end shell 3 is the outer shell of the male end, and the female end shell 2 is the outer shell of the female end; the male end shell 3 is plugged into the female end shell 2; the auxiliary shielding structure 4 and the electromagnetic shielding structure 1 are respectively arranged at both ends of the female end shell 2; the auxiliary shielding structure 4 is arranged in the cable line 5 connection side of the female end shell 2, and the auxiliary shielding structure 4 is arranged in coordination with the female end cable line 5; the electromagnetic shielding structure 1 is detachably arranged on one end where the female end shell 2 and the male end shell 3 are plugged.

[0056] The electromagnetic shielding structure 1 is installed in a ring shape on the outer periphery of the female end shell 2, so that the electromagnetic shielding structure 1 forms an electromagnetic shielding layer. The electromagnetic shielding layer blocks the electromagnetic waves generated by the male and female terminals during the plug-in process from radiating to the outside of the terminal shell. In addition, the electromagnetic radiation outside the shell is also blocked to prevent external radiation from interfering with the internal connectors, thereby ensuring the electromagnetic stability of the male and female connectors.

[0057] Specifically, two clearance grooves 23 are provided on the end of the mating side of the female end housing 2 and the male end housing 3, which are recessed inwardly along the male end plugging direction. The clearance grooves 23 are provided in cooperation with the protrusions 31 on the end side wall of the male end; two electromagnetic shielding structures 1 are provided, and the electromagnetic shielding structure 1 is detachably installed between two adjacent clearance grooves 23. The clearance grooves 23 are provided in cooperation with the protrusions 31 to ensure the installation stability of the male and female terminals; the electromagnetic shielding structure 1 is installed at intervals between the adjacent clearance grooves 23, and while meeting the installation stability of the male and female terminals, the installation of the electromagnetic shielding structure 1 further ensures the shielding effect of the male and female connectors on internal and external radiation, and improves the stability of the shielding.

[0058] like Figure 2 , Figure 3 and Figure 4 As shown, the electromagnetic shielding structure 1 in this embodiment includes a mounting body 11, a swivel mounting portion 12 and a plurality of first elastic pieces 13 arranged in an integral structure. The mounting body 11 is mounted in the female end housing 2, and the mounting body 11 has a limited plug-in end 111 which is limitedly inserted into the first mounting structure in the female end housing 2; one end of the swivel mounting portion 12 is connected to the mounting body 11, and the other end is swivel outward along the edge of the female end housing 2 and mounted on the second mounting structure outside the female end housing 2; one end of the first elastic piece 13 is mounted on the mounting body 11, and the other end of the first elastic piece 13 is elastically connected to the male end housing 3.

[0059] The number of the above-mentioned first spring pieces 13 can be set according to specific usage requirements. The actual requirements may include the required tightness of the male end plug-in. The more the number of first spring pieces 13 is set, the tighter the contact between the first spring pieces 13 and the male end is, that is, the more stable the electromagnetic shielding effect is.

[0060] Specifically, the first mounting structure is a limiting mounting groove 21, and the limiting plug end 111 is inserted into the limiting mounting groove 21; the limiting mounting groove 21 has a first limiting wall, and the limiting plug end 111 abuts against the first limiting wall to limit the mounting body 11 to flip and detach from the female end housing 2. The limiting plug end 111 is the end of the mounting body close to the female end housing 2; the limiting mounting groove 21 is extended and arranged parallel to the insertion direction of the male end housing 3.

[0061] Specifically, if Figure 4 As shown, the second mounting structure is a limiting protrusion 22 protruding outwardly along the outer wall surface; a mounting hole 121 is provided on the rotary mounting portion 12, and the mounting hole 121 is buckled with the limiting protrusion 22.

[0062] In this embodiment, the auxiliary shielding structure 4 has a limit installation part 41 and a second spring part 42, the limit installation part 41 is installed in the female end housing 2, one end of the second spring part 42 is connected to the limit installation part 41, and the other end is connected to the cable 5. The auxiliary shielding structure 4 also includes a limit abutment part 43, and the limit abutment part 43 abuts against one end of the cable 5 close to the female end housing 2. The above-mentioned auxiliary shielding function is set to connect the shielding layer of the cable 5 with the metal shell of the female end, thereby forming a complete connector shielding system together with the aforementioned electromagnetic shielding structure 1, further ensuring the internal and external radiation shielding effect of the male and female end connection and the high-voltage distribution box as a whole, and improving the stability of the shielding.

[0063] In this embodiment, when installing the electromagnetic shielding system, when installing the electromagnetic shielding structure 1: first, follow the steps as follows: Figure 2 The male end housing is slid into the female end housing in the direction A shown in the figure, so that the mounting hole 121 and the limiting protrusion 22 are interlocked, and the limiting plug end 111 is inserted into the limiting mounting groove 21 of the female end housing. Figure 2 Insert the female end housing in the direction A shown in the figure, and the first spring piece 13 and the male end metal shell are elastically abutted against each other; for the shielding installation on one side of the cable 5: first, follow the direction as shown in the figure Figure 2 The auxiliary shielding structure 4 is installed in the B direction as shown. After the auxiliary shielding structure 4 is installed, the cable 5 is inserted into the installation position of the cable 5. At this point, the complete electromagnetic shielding system is completed. The disassembly process is the opposite of the aforementioned installation process, and no further details are given here.

[0064] In the electromagnetic shielding structure 1 provided in this embodiment, the first mounting structure and the second mounting structure on the female end shell 2 are interconnected with the limiting plug-in end 111 and the rotating mounting part 12, so that the electromagnetic shielding structure 1 and the inner and outer sides of the female end shell 2 can be limited, and when either side of the electromagnetic shielding structure 1 is subjected to force during the plugging and unplugging of the male and female terminals, the electromagnetic shielding structure 1 will not be displaced; at the same time, the electromagnetic shielding structure 1 does not need other structures to limit it separately, but is directly assembled with the female end shell 2 through its own limiting part, thereby ensuring that the male and female ends will not be displaced due to the action of external forces during installation and disassembly; thereby, while improving the installation reliability of the electromagnetic shielding structure 1, there is no need to set other limiting mounting structures separately, thereby ensuring that the disassembly and assembly of the shielding structure is simple and convenient. Specifically, firstly, the setting of the limiting installation groove 21, when the male and female terminals are plugged in and out, the electromagnetic shielding structure 1 is subjected to a force along the plugging and unplugging direction of the male end. At the same time, since the first spring sheet part 13 is connected to the male end shell 3, there is also a force in the force direction of the electromagnetic shielding structure 1 that drives the electromagnetic shielding structure 1 to reverse as a whole. Therefore, the first limiting wall and the outer wall surface of the limiting plug-in end 111 abut against each other, thereby suppressing the action of the male and female ends driving the electromagnetic shielding structure 1 to reverse during the plugging and unplugging process, further ensuring the stability of the installation of the electromagnetic shielding structure 1 during the plugging and unplugging of the male and female ends. Secondly, during the plugging and unplugging of the male and female terminals, the rotary installation part 12 in the electromagnetic shielding structure 1 not only ensures the stability of the installation by abutting against the outer wall surface of the female end shell 2, but also ensures the stability of the installation of the electromagnetic shielding structure 1 through the limiting effect of the relief protrusion and the installation hole 121, further ensuring the reliability of the installation.

[0065] Example 2

[0066] This embodiment provides a shielding system, which is different from the shielding system provided in Example 1 in that: the position of the limiting installation groove 21 of the first installation structure is different, the limiting installation groove 21 can be extended along the insertion direction perpendicular to the male end shell 3, the limiting plug end 111 is a limiting protrusion 22 protruding in the perpendicular insertion direction, and the limiting protrusion 22 abuts against the inner wall of the limiting installation groove 21 to limit the installation body from the female end shell 2. The setting position of the first installation structure of different female end shells 2 is matched with the limiting plug end 111 of different electromagnetic shielding structures 1, which is convenient for users to set different first installation structures according to specific use environments, thereby improving the adaptability of the electromagnetic shielding structure 1.

[0067] Example 3

[0068] This embodiment provides a shielding system, which is different from the shielding system provided in Example 1 or Example 2 in that the grooves and protrusions that cooperate with each other between the above-mentioned limiting plug-in terminal and the female end shell can be interchanged, that is, a protrusion can be provided at the female end shell, and a groove can be provided at the plug-in terminal, and the groove and the protrusion are plugged into each other, which can also realize the fixation of the electromagnetic shielding structure and the rapid disassembly and assembly of the electromagnetic shielding structure and the female end shell.

[0069] Example 4

[0070] This embodiment provides a shielding system, which is different from the shielding system provided in any one of Embodiments 1 to 3 in that the auxiliary shielding structure 4, the cable line 5 and the female housing 2 are installed in different ways. The auxiliary shielding structure 4 can also be first crimped with the cable line 5, and then the auxiliary shielding structure 4 and the cable line 5 are installed together on the cable line 5 installation side of the female housing 2. Obviously, the above embodiments are only examples for clear explanation, and are not limitations on the implementation methods. For ordinary technicians in the field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the invention.
