Description

Technical Field

[0001] This application relates to the technical field of connectors, and particularly to a plug assembly, a connector, and a vehicle. Background Art

[0002] When assembling the plug assembly of the prior art connector, usually the internal structures such as the wire harness, terminals, and shielding ring are first assembled into a whole, and then the internal structure is assembled inside the housing. This assembly method has the following disadvantages:

[0003] First, the number of internal structure parts is large, and complex fixing structures need to be provided inside the housing, resulting in a large demand for the installation space inside the housing, increasing the size and cost of the plug assembly;

[0004] Second, in order to adapt to the housing, internal structures such as terminals need to be customized and developed according to the wire outlet angle of the housing, resulting in a relatively fixed wire outlet angle. Summary of the Utility Model

[0005] The purpose of this application is to provide a plug assembly, a connector, and a vehicle, which have a simple structure, a compact size, a low cost, and a flexible wire outlet angle.

[0006] To solve the above technical problems, this application provides a plug assembly, including a main body structure. The main body structure includes plug terminals, a wire, and a housing. The wire is an unshielded wire. The end of the wire is connected to the plug terminals. The housing, the plug terminals, and the wire are connected into one body by insert molding. The housing covers at least the connection part of the plug terminals and the wire. The plug assembly further includes a shielding structure. The shielding structure is partially sleeved on the outer periphery of the housing. A shielding space is formed inside the shielding structure. The main body structure is located inside the shielding space.

[0007] In the plug assembly of this embodiment, the wire adopts an unshielded wire, that is, the wire includes a cable and an insulating layer wrapped around the outer periphery of the cable. The structure of the wire is simple, the cross-sectional size is smaller, and the space requirement for the interior of the housing is also smaller. Correspondingly, this embodiment adopts an external shielding structure setting method. After the plug terminal and the wire are correspondingly connected, the housing, the plug terminal, and the wire are connected into one body through insert molding. The number of internal parts of the housing is reduced, and there is no need to set up a complex fixing structure, reducing the requirement for the internal installation space of the housing, making the size of the plug assembly more compact and reducing costs. At the same time, the housing, the plug terminal, and the wire are integrally injection-molded and fixed. The housing can be formed into the required shape according to the connection angle of the plug terminal and the wire. The plug terminals of the same structural form can meet any wire outlet angle, making the wire outlet angle of the plug assembly more flexible. The shielding structure is partially sleeved on the outer periphery of the housing, and the main structure is located inside the shielding space formed by the shielding structure, that is, the overall shielding method is adopted, which meets the shielding effect without occupying the internal space of the housing.

[0008] In some embodiments, the shielding structure includes a plug shielding shell and a wire shielding layer. The plug shielding shell is sleeved on the outer periphery of the housing and axially covers at least part of the housing. The end of the wire shielding layer is connected to the plug shielding shell, and the shielding space is formed inside the plug shielding shell and the wire shielding layer.

[0009] In some embodiments, the end of the wire shielding layer is sleeved on the outer periphery of the plug shielding shell and axially covers part of the plug shielding shell.

[0010] In some embodiments, the wire shielding layer is a sheet structure. The end of the wire shielding layer is curled and wrapped around the outer periphery of the plug shielding shell. The plug assembly further includes a fixing member configured to fix the wire shielding layer to the plug shielding shell.

[0011] In some embodiments, the fixing member includes a binding strap. The binding strap is bundled around the outer periphery of the wire shielding layer to fix the corresponding end of the wire shielding layer to the plug shielding shell.

[0012] In some embodiments, among the inner peripheral wall of the plug shielding shell and the outer peripheral wall of the housing, one is provided with a barbed structure and the other is provided with a card slot, and the barbed structure is snapped into the card slot.

[0013] In some embodiments, an installation cavity surrounding the wire is provided inside the housing. The installation cavity penetrates the end wall of the wire outlet end of the housing. The plug assembly further includes a sealing ring and a tail cover. The sealing ring is installed between the outer peripheral wall of the wire and the inner peripheral wall of the installation cavity by interference fit and seals along the circumferential direction. The tail cover is connected to the housing to close the installation cavity. The tail cover is correspondingly provided with a through hole for the wire to pass through.

[0014] In some embodiments, there is a spacing between the end of the plug shield near the wire outlet end and the tail cover.

[0015] In some embodiments, the plug assembly further includes a torque wrench. The torque wrench is located outside the plug shield. There is a sliding fit portion between the torque wrench and the housing. The torque wrench and the housing are slidably fitted through the sliding fit portion. The plug shield is provided with an avoidance opening for avoiding the sliding fit portion.

[0016] This application also provides a connector, including the aforementioned plug assembly and a socket assembly. The socket assembly and the plug assembly are correspondingly plugged and fitted.

[0017] The connector of this application includes the aforementioned plug assembly, so it has the same technical effects as the aforementioned plug assembly and will not be elaborated here.

[0018] This application also provides a vehicle, including an electrical device with a wiring terminal, and the aforementioned connector. The socket assembly in the connector is correspondingly connected to the wiring terminal.

[0019] The vehicle of this application includes the aforementioned connector, so it has the same technical effects as the aforementioned connector and will not be elaborated here. Description of the Drawings

Detailed implementation mode

[0025] Before describing the technical solution of the present application, a brief introduction will be given to the structure and assembly method of the prior art plug assembly.

[0026] The prior art plug assembly includes an internal structure and an outer shell. The internal structure includes a plug terminal, a shielding ring, and a cable connection assembly. The cable connection assembly includes a cable, an inner insulating layer, a shielding layer, an outer insulating layer, and an end locking sleeve, etc. The shielding ring is sleeved outside the plug terminal to play a role in shielding electromagnetic interference. The inner insulating layer, the shielding layer, and the outer insulating layer are sequentially wrapped outside the cable from the inside to the outside. The shielding layer has a shielding layer flange that turns outward from the end of the outer insulating layer. The shielding ring is sleeved outside the shielding layer flange, and the shielding layer flange is closely attached to the shielding ring under the support of the end locking sleeve. After the internal structures such as the plug terminal, the shielding ring, and the cable connection assembly are assembled, they are then integrally assembled into the inner part of the outer shell.

[0027] It can be seen from the above that in the prior art plug assembly, the structure of the cable connection assembly is complex, and the connection between the shielding ring and the shielding layer of the cable connection assembly is also arranged inside the outer shell. There are many parts installed inside the outer shell, and complex fixing structures need to be arranged inside the outer shell, resulting in a large demand for the installation space inside the outer shell, increasing the size of the plug assembly and the cost.

[0028] In addition, in the connectors applied to new energy vehicles, the plug assembly has various wire outlet angles, such as 90°, 120°, 150°, 180°, etc. The outer shell is pre-processed according to different wire outlet angles. In order to adapt to the structure of the outer shell, internal structures such as plug terminals also need to be re-customized and developed, resulting in relatively fixed wire outlet angles of the plug assembly. Moreover, when the wire outlet angle of the plug assembly is not 180°, such as 90°, 120°, or 150°, in order for the internal structure to be smoothly assembled into the inner part of the outer shell, the internal space of the outer shell needs to be further increased, thereby further increasing the size of the plug assembly.

[0029] Based on the problems existing in the prior art plug assembly, the present application provides a brand-new plug assembly. In order to enable those skilled in the art to better understand the technical solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In this article, one end of the plug component for plugging and mating with the socket component is the "mating end", and the end where the wire 2 of the plug component extends out is the "outlet end".

[0031] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a specific embodiment of the plug component provided by this application.

[0032] This application discloses a plug component, which includes a main structure. The main structure includes a plug terminal 1, a wire 2, and a housing 3. The wire 2 is an unshielded wire. The end of the wire 2 is correspondingly connected to the plug terminal 1. The housing 3, the plug terminal 1, and the wire 2 are connected integrally through insert molding. The housing 3 at least covers the connection part of the plug terminal 1 and the wire 2.

[0033] The plug component further includes a shielding structure 4. The shielding structure 4 is partially sleeved on the outer periphery of the housing 3. A shielding space is formed inside the shielding structure 4, and the main structure is located inside the shielding space.

[0034] In a plug component of this application, the wire 2 uses an unshielded wire, that is, the wire 2 includes a cable, and an insulating layer wrapped around the outer periphery of the cable. Compared with traditional cable connection components, the structure of the unshielded wire is simpler, the cross-sectional size is smaller, and the space requirement for the inside of the housing 3 is also smaller. The wire 2 uses an unshielded wire. Correspondingly, the plug component adopts an external shielding structure setting method. After the plug terminal 1 and the wire 2 are correspondingly connected, the housing 3, the plug terminal 1, and the wire 2 are connected integrally through insert molding. The number of internal parts of the housing 3 is greatly reduced. Moreover, compared with the traditional assembly method, there is no need to set up complex fixing structures inside the housing 3, and the requirement for the internal installation space of the housing 3 is reduced, making the size of the plug component more compact and reducing costs. At the same time, the housing 3 is integrally injection-molded and fixed to the plug terminal 1 and the wire 2. The housing 3 can be formed into the required shape according to the connection angle of the plug terminal 1 and the wire 2. The plug terminal 1 of the same structural form can meet any outlet angle, making the outlet angle of the plug component more flexible.

[0035] In addition, the shielding structure 4 is partially sleeved on the outer periphery of the housing 3, and the main structure is located inside the shielding space formed by the shielding structure 4, that is, the overall shielding method is adopted. While meeting the shielding effect, it does not occupy the internal space of the housing 3.

[0036] As described above, the end of the wire 2 is correspondingly connected to the plug terminal 1. Specifically, the end of the cable is correspondingly connected to the plug terminal 1. The connection method between the plug terminal 1 and the cable is not limited. It can be fixed by welding, such as using ultrasonic welding, etc., or it can be fixed by crimping to ensure the reliable connection between the plug terminal 1 and the cable 2.

[0037] As described above, the housing 3, the plug terminal 1 and the wire 2 are integrally connected by insert molding. The housing 3 covers at least the connection part of the plug terminal 1 and the wire 2. Generally, the plug terminal 1 is located inside the housing 3, and part of the wire 2 is located inside the housing 3. The number of the plug terminals 1 and the wires 2 is adaptively adjusted according to the number of positions of the connector, and no specific limitation is made here.

[0038] Please continue to refer to Figure 1 , in this embodiment, the shielding structure 4 specifically includes a plug shielding case 41 and a wire shielding layer 42. The plug shielding case 41 is sleeved on the outer periphery of the housing 3 and axially covers at least part of the area of the housing 3. The end of the wire shielding layer 42 is connected to the plug shielding case 41, and a shielding space is formed inside the plug shielding case 41 and the wire shielding layer 42.

[0039] It can be understood that in practice, two plug assemblies are formed at both ends of the wire 2, and the two plug assemblies share the same wire shielding layer 42, that is, both ends of the wire shielding layer 42 are respectively connected to the plug shielding cases 41 at the corresponding ends. In this way, during installation, first, the plug shielding case 41 is sleeved on the outer periphery of the housing 3 and axially covers at least part of the area of the housing 3. The plug shielding case 41 is used to shield at least part of the area of the housing 3 and its internal structure. Then, the wire shielding layer 42 is connected to the two plug shielding cases 41 at both ends. The wire shielding layer 42 is used to shield the remaining area of the housing 3 and its internal structure, as well as the part of the wire 2 exposed outside the housing 3. In short, the plug shielding case 41 and the wire shielding layer 42 work together to axially cover the entire main structure of the plug assembly to meet the shielding requirements. At the same time, the shielding structure 4 adopts the split structure of the plug shielding case 41 and the wire shielding layer 42 as above, which is more convenient for installation.

[0040] Further, in this embodiment, the end of the wire shielding layer 42 is sleeved on the outer periphery of the plug shielding case 41 and axially covers part of the area of the plug shielding case 41.

[0041] In this way, the wire shielding layer 42 and the plug shielding case 41 partially overlap axially, ensuring that there is no gap in the shielding structure 4 axially, avoiding electromagnetic leakage, and meeting the shielding requirements.

[0042] Among them, the wire shielding layer 42 can be a sheet structure. The end of the wire shielding layer 42 is curled and wrapped around the outer periphery of the plug shielding case 41. The plug assembly further includes a fixing member configured to fix the wire shielding layer 42 to the plug shielding case 41.

[0043] With the above settings, during installation, the wire shielding layer 42 in the unfolded state can be first placed on one side of the wire 2. The length direction of the wire shielding layer 42 is along the extension direction of the wire 2, and both ends in the length direction of the wire shielding layer 42 are respectively attached to the corresponding outer wall surfaces of the plug shielding shell 41. Then, both ends in the width direction of the wire shielding layer 42 are gathered together along the outer wall surface of the plug shielding shell 41. The length in the width direction of the wire shielding layer 42 is set to be not less than the circumference of the plug shielding shell 41. In this way, when the wire shielding layer 42 wraps around the outer circumference of the plug shielding shell 41, both ends in the width direction of the wire shielding layer 42 are seamlessly connected in the circumferential direction, so that the wire shielding layer 42 is closed in the circumferential direction, ensuring reliable shielding. Finally, the wire shielding layer 42 is fixed to the plug shielding shell 41 through a fixing member, so that the wire shielding layer 42 always maintains the above-mentioned curled state and plays the shielding function.

[0044] It can be seen that the wire shielding layer 42 adopts the above-mentioned sheet structure, which makes the installation process of the wire shielding layer 42 more convenient and fast. And the wire shielding layer 42 curls correspondingly according to the outer wall surface of the plug shielding shell 41, and the wire shielding layer 42 can be closely attached to the plug shielding shell 41. Finally, it is fixed through a fixing member, and the connection is reliable.

[0045] In this embodiment, the fixing member includes a cable tie. The cable tie is tied around the outer circumference of the wire shielding layer 42. While realizing the circumferential fixation of the wire shielding layer 42, the wire shielding layer 42 is fixed to the plug shielding shell 41, with reliable fixation and convenient adjustment.

[0046] In practice, the fixing member can also be in other forms, such as a binding rope, etc. The binding rope is tied around the outer circumference of the wire shielding layer 42. After the two ends of the binding rope are connected, the circumferential fixation of the wire shielding layer 42 is realized. The binding rope can be a string, a steel wire rope, etc.

[0047] Or, the fixing member is not limited to the above-mentioned bundling and fixing methods. For example, the fixing member includes a magic tape. Specifically, the magic tape includes a hook surface and a loop surface of the magic tape. Define the wall surface of the wire shielding layer 42 facing the plug shielding shell 41 as the inner wall surface, and the wall surface of the wire shielding layer 42 facing away from the plug shielding shell 41 as the outer wall surface. Among the hook surface and the loop surface of the magic tape, one is connected to the inner wall surface of the wire shielding layer 42 and is located at the first end in the width direction of the wire shielding layer 42, and the other is connected to the outer wall surface of the wire shielding layer 42 and is located at the second end in the width direction of the wire shielding layer 42. During installation, after the wire shielding layer 42 wraps around the outer circumference of the plug shielding shell 41, the hook surface and the loop surface of the magic tape are adhesively bonded to each other, realizing the circumferential fixation of the wire shielding layer 42 and connecting the wire shielding layer 42 and the plug shielding shell 41 together.

[0048] In this embodiment, the wire shielding layer 42 can be a shielding braided net or other shielding sheet materials, etc.

[0049] As described above, the plug shielding case 41 is sleeved on the outer periphery of the outer case 3. To fix the plug shielding case 41 to the outer case 3 and ensure the stable installation of the plug shielding case 41, in some embodiments of the present application, among the inner peripheral wall of the plug shielding case 41 and the outer peripheral wall of the outer case 3, one is provided with a barbed structure and the other is provided with a card slot, and the barbed structure is snapped into the card slot.

[0050] Specifically, taking the example where the barbed structure is provided on the inner peripheral wall of the plug shielding case 41 and the card slot is provided on the outer peripheral wall of the outer case 3, the end where the barbed structure is connected to the inner peripheral wall of the plug shielding case 41 is defined as the root, and the other end is the free end. The extending direction of the barbed structure from the root to the free end is the inclined direction. Combining Figure 1 with the understanding, the inclined direction of the barbed structure should be inclined from right to left. In this way, during installation, the plug shielding case 41 can be installed on the outer periphery of the corresponding outer case 3 from left to right, and the barbed structure will be correspondingly snapped into the card slot. The plug shielding case 41 is not easily detached from the outer case 3, ensuring the reliable connection between the plug shielding case 41 and the outer case 3.

[0051] In practice, it is feasible to set one or more barbed structures. When the number of barbed structures is multiple, the anti-detachment effect is better, and the number of card slots only needs to match the number of barbed structures.

[0052] Of course, the fixing method between the plug shielding case 41 and the outer case 3 is not limited to the above. For example, the plug shielding case 41 and the outer case 3 can also adopt interference fit, etc.

[0053] Please continue to refer to Figure 1 , in this embodiment, the outer case 3 has an installation cavity surrounding the wire 2, and the installation cavity penetrates the end wall of the wire outlet end of the outer case 3. The plug assembly further includes a sealing ring 5 and a tail cover 6. The sealing ring 5 is installed between the outer peripheral wall of the wire 2 and the inner peripheral wall of the installation cavity by interference fit and seals along the circumferential direction. The tail cover 6 is connected to the outer case 3 to close the installation cavity, and the tail cover 6 is correspondingly provided with a through hole for the wire 2 to pass through.

[0054] In this embodiment, the above-mentioned installation cavity is arranged inside the outer shell 3, and at the same time, a sealing ring 5 is added. The sealing ring 5 can be assembled into the installation cavity from the open end of the installation cavity after the outer shell 3 is injection-molded. In this way, the sealing ring 5 can adopt an interference fit installation method, so that in the installed state, the inner peripheral wall of the sealing ring 5 is closely attached to the outer peripheral wall of the wire 2, and the outer peripheral wall of the sealing ring 5 is closely attached to the inner peripheral wall of the installation cavity, realizing reliable circumferential sealing between the wire 2 and the outer shell 3, and preventing external impurities such as dust and moisture from entering the inside of the plug assembly through the gaps between the mating surfaces; at the same time, since the insulating layer of the wire 2 and the material of the outer shell 3 are different, and the thermal expansion coefficients are also different, after long-term use, a gap may be generated between the wire 2 and the outer shell 3 due to the difference in thermal expansion coefficients. However, the sealing ring 5 adopts an interference fit installation method, and even if a gap is generated, the sealing ring 5 can deform under the action of its own restoring force, thereby compensating for the gap and ensuring reliable sealing between the wire 2 and the outer shell 3 all the time, improving the service life of the plug assembly.

[0055] At the same time, in this embodiment, a tail cover 6 is also added. The tail cover 6 is connected to the outer shell 3 to close the installation cavity. On the one hand, it can play an axial limiting role on the sealing ring 5 to prevent the sealing ring 5 from detaching from the inside of the installation cavity; on the other hand, the tail cover 6 can encapsulate the sealing ring 5 inside the installation cavity, playing a shielding role to avoid the exposure of the sealing ring 5, making the overall structure of the plug assembly neater and the user experience better.

[0056] Among them, the installation cavity can be formed during the injection molding process of the outer shell 3; the material of the sealing ring 5 includes but is not limited to rubber, etc.; the connection method of the tail cover 6 connected to the outer shell 3 is not limited. For example, the tail cover 6 and the outer shell 3 can be snap-fitted and fixed. Specifically, among the tail cover 6 and the outer shell 3, one is provided with a snap-fit protrusion, and the other is provided with a snap-fit groove, and the snap-fit protrusion is snapped into the corresponding snap-fit groove to realize the connection between the tail cover 6 and the outer shell 3.

[0057] In practice, the tail cover 6 can adopt an integral structure or a split structure. The integral structure means that the number of the tail covers 6 is one, and the number of through holes provided in the tail cover 6 is the same as the number of the wires 2, and each wire 2 passes through the corresponding through hole; the split structure means that the number of the tail covers 6 is the same as the number of the wires 2, and each tail cover 6 is provided with a through hole, and the wire 2 passes through the through hole in the corresponding tail cover 6.

[0058] From Figure 1 It can be seen that in this embodiment, there is a spacing between the end of the plug shielding shell 41 near the wire outlet end and the tail cover 6. In this way, the plug shielding shell 41 can avoid the tail cover 6, facilitating the connection between the tail cover 6 and the outer shell 3, and the part of the outer shell 3 exposed outside the plug shielding shell 41 is shielded by the wire shielding layer 42.

[0059] In practice, it is also feasible that the rear end of the plug shielding case 41 extends to be flush with the rear end edge of the outer case 3. At this time, the plug shielding case 41 can be provided with an avoidance portion, and the connection structure between the end cap 6 and the outer case 3 can pass through the avoidance portion to achieve connection. Of course, the setting method of this embodiment has a simple structure, saves materials, reduces costs, omits the processing steps of the avoidance portion, improves the processing efficiency, and is a more preferable technical solution.

[0060] Please continue to refer to Figure 1 , in this embodiment, the plug assembly further includes a power-assisted wrench 7. The power-assisted wrench 7 is located outside the plug shielding case 41. There is a sliding fit portion between the power-assisted wrench 7 and the outer case 3. The power-assisted wrench 7 and the outer case 3 are slidably fitted through the sliding fit portion. The plug shielding case 41 is provided with an avoidance opening for avoiding the sliding fit portion.

[0061] Among them, the specific structure and power-assisted principle of the power-assisted wrench 7 are well-known prior arts to those skilled in the art and will not be elaborated here. Here, the positional relationship between the power-assisted wrench 7 and the plug shielding case 41 will be mainly described. It can be seen that in this embodiment, since the plug shielding case 41 is installed outside the outer case 3 and the power-assisted wrench 7 is located outside the plug shielding case 41, the plug shielding case 41 needs to be provided with an avoidance opening so that the sliding fit portion can pass through the avoidance opening to achieve the sliding fit between the power-assisted wrench 7 and the outer case 3. In practice, the size of the avoidance opening provided in the plug shielding case 41 should ensure that it does not affect the shielding effect of the plug shielding case 41.

[0062] Among them, the sliding fit portion specifically includes a sliding portion and a groove portion. One of the sliding portion and the groove portion is provided on the power-assisted wrench 7, and the other is provided on the outer case 3. The sliding portion passes through the avoidance opening and is at least partially clamped in the groove portion.

[0063] Furthermore, as Figure 1 shown, in this embodiment, the plug assembly further includes a mating sealing ring 8. When the plug assembly and the socket assembly are plugged and mated, the mating sealing ring 8 is located between the mating surfaces of the plug assembly and the socket assembly and functions as a seal.

[0064] Specifically, the outer case 3 includes an annular inner wall 31 and an annular outer wall. An annular space is formed between the annular inner wall 31 and the annular outer wall. The plug terminal 1 is located inside the annular inner wall 31. An installation groove is provided on the outer peripheral wall of the annular inner wall 31, and the mating sealing ring 8 is installed inside the installation groove. In this way, when the plug assembly and the socket assembly are plugged and mated, the mating wall of the socket assembly is sleeved on the outer periphery of the annular inner wall 31, and the two are circumferentially sealed through the mating sealing ring 8.

[0065] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a specific embodiment of the connector provided by this application.

[0066] The present application also provides a connector, which includes the aforementioned plug assembly and further includes a socket assembly. The socket assembly and the plug assembly are correspondingly plugged and matched.

[0067] The connector of the present application includes the aforementioned plug assembly, and thus has the same technical effects as the aforementioned plug assembly, which will not be elaborated herein.

[0068] Among them, from Figure 2 It can be seen that the socket assembly includes a socket sealing ring 9, a socket housing 10, socket terminals 11 and a socket shielding case 12. The socket housing 10 includes an inner ring wall and an outer ring wall, and an annular space is formed between the inner ring wall and the outer ring wall. The socket terminals 11 are located inside the inner ring wall. One end of the socket terminal 11 forms a plug contact portion 111 for plugging and matching with the plug terminal 1 of the plug assembly, and the other end forms a copper bus bar locking portion 112. The copper bus bar locking portion 112 extends out from the inside of the socket housing 10 for connecting with the wiring terminal of the electrical equipment. The socket shielding case 12 is installed on the outer periphery of the inner ring wall to play a role in shielding electromagnetic interference. After the socket terminal 11 and the plug terminal 1 are plugged and matched, the socket shielding case 12 and the plug shielding case 41 partially overlap axially to ensure reliable shielding. The socket sealing ring 9 is installed on the connecting end face of the socket housing 10. When the socket assembly is connected to the electrical equipment, the connecting end face of the socket housing 10 and the connecting end face of the electrical equipment are sealed through the socket sealing ring 9.

[0069] In practice, the plug contact portion 111 and the copper bus bar locking portion 112 of the socket terminal 11 can be of an integral structure; they can also be of a split structure and then connected together.

[0070] The connector of the present application can be a high-voltage connector, and the high-voltage connector can be compatible with the high-voltage interlock function to detect the connection state of the high-voltage system and ensure the safety of the high-voltage system. Among them, the high-voltage interlock is a well-known prior art to those skilled in the art and will not be elaborated herein.

[0071] The present application also provides a vehicle, which includes an electrical equipment having a wiring terminal and further includes a connector. The socket assembly in the connector is correspondingly connected to the wiring terminal.

[0072] The vehicle of the present application includes the aforementioned connector, and thus has the same technical effects as the aforementioned connector, which will not be elaborated herein.

[0073] From Figure 3 It can be seen that the plug assemblies of the two groups of connectors are connected together by the same wire 2. The socket assemblies of the connectors are installed on the corresponding electrical equipment. After the socket assemblies and the plug assemblies are correspondingly plugged and matched, the electrical connection of the two electrical equipment is realized; at the same time, the connector of the present application belongs to a quick-connect type connector, which can realize the quick connection and disconnection of the electrical equipment, is convenient and fast to operate, and improves the work efficiency.

[0074] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
