Technical Field

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

[0002] In the related art, a split structure design is adopted between the end cap and the fixed cap of a vehicle wire harness connector. When assembling the wire harness connector, the fixed cap is assembled by the connector manufacturer, while the wire threading action and the end cap buckling action of the wire harness connector are carried out in the wire harness factory, which requires multiple assemblers to operate, resulting in a waste of human resources and low assembly efficiency. Summary of the Utility Model

[0003] Embodiments of this application provide a connector and a vehicle to solve or improve the technical problem that during the assembly of the connector, the installation needs to be carried out separately by the staff of multiple manufacturers, resulting in a waste of human resources and low assembly efficiency.

[0004] A connector according to an embodiment of this application is used for a vehicle. The connector includes a sheath and a housing. Among them, the sheath is provided with a receiving cavity; the housing includes a fixed cap portion, a connecting portion, and an end cap portion, and the fixed cap portion is connected to the end cap portion through the connecting portion; when the sheath is connected to the housing, the fixed cap portion and the connecting portion are located in the receiving cavity.

[0005] In this way, by providing a connecting portion on the connector, when assembling the sheath after the wire harness is fixed to the fixed cap portion, it can drive the fixed cap portion to move towards the end cap portion, so that the fixed cap portion and the end cap portion can be fixedly connected in the receiving cavity. Furthermore, the assembly of the fixed cap portion, the wire threading action, and the end cap buckling action do not need to be carried out separately, reducing the number of assemblers involved, reducing the waste of human resources, and improving the assembly efficiency.

[0006] In some embodiments, the end cap portion is provided with a receiving cavity, the sheath is provided with a plurality of first locking portions, and the end cap portion is provided with a plurality of second locking portions. The first locking portions are evenly distributed on the end face of the sheath close to the orifice of the receiving cavity, and the second locking portions are evenly distributed on the end face of the end cap portion close to the orifice of the receiving cavity. Each first locking portion is locked with a corresponding second locking portion.

[0007] In this way, by providing the first locking portions on the sheath and the second locking portions on the end cap portion, and the first locking portions can cooperate with the second locking portions to lock, so that the sheath can be fixed to the end cap portion.

[0008] In some embodiments, the first locking portion includes a first snap head, and the second locking portion includes a first snap groove, and the first snap groove is adapted to be engaged with the first snap head.

[0009] In this way, the shapes of the first buckle head and the first buckle groove match. When the first buckle head enters the first buckle groove, the tightness and stability between the sheath and the tail cover part can be increased.

[0010] In some embodiments, the sheath is provided with a plurality of third locking parts, and the fixed cover part is provided with a plurality of fourth locking parts. The third locking parts are evenly distributed on the inner wall of the accommodating cavity, and the fourth locking parts are evenly distributed on the periphery of the fixed cover part. Each of the third locking parts is locked with a corresponding one of the fourth locking parts.

[0011] In this way, by providing the third locking parts on the sheath and the fourth locking parts on the fixed cover part, and the third locking parts can cooperate with the fourth locking parts to lock, so that the sheath can be fixed to the fixed cover part.

[0012] In some embodiments, the third locking part includes a second buckle groove, and the fourth locking part includes a second buckle head and an elastic hole. The second buckle head is provided on the side of the fixed cover part, and the elastic hole is located between the side and the center of the fixed cover part and is close to the second buckle head. The second buckle groove is adapted to be engaged with the second buckle head.

[0013] In this way, by providing the elastic hole on the side of the second buckle head, the second buckle head can be easily elastically deformed. The shapes of the second buckle head and the second buckle groove match. When the first buckle head enters the first buckle groove, the tightness and stability between the sheath and the tail cover part can be increased.

[0014] In some embodiments, the length of the elastic hole is greater than the length of the second buckle head.

[0015] In this way, by setting the length of the elastic hole to be greater than the length of the second buckle head, it is beneficial for the second buckle head to elastically deform, reduce the wear of the second buckle head, and reduce the risk of the fixed cover part falling off.

[0016] In some embodiments, the fixed cover part, the connecting part, and the tail cover part are of an integral structure.

[0017] In this way, by designing the fixed cover part, the connecting part, and the tail cover part as an integral structure, the housing can be assembled without being separated during assembly, reducing the number of assembly personnel involved, reducing the waste of human resources, and improving the assembly efficiency.

[0018] In some embodiments, the tail cover part is provided with a receiving cavity, and the tail cover part includes a wire clamping hole. The wire clamping hole is provided on the side of the tail cover part and is communicated with the receiving cavity.

[0019] In this way, by providing a wire clamping hole on the side surface of the end cover part, the wire clamping hole can be made to communicate with the accommodation cavity, so that the wire harness in the vehicle can enter the accommodation cavity through the wire clamping hole.

[0020] In some embodiments, the gap of the wire clamping hole is smaller than the minimum wire diameter of the crimped wire harness, and the inner hanging dimension of the wire clamping hole is larger than the maximum wire diameter requirement of the wire harness.

[0021] In this way, by setting the gap of the wire clamping hole to be smaller than the minimum wire diameter of the wire harness crimping, it is possible to prevent the wire harness from being disengaged from the accommodation cavity due to external force after the wire harness enters the accommodation cavity. By setting the inner hanging dimension of the wire clamping hole to be larger than the maximum wire diameter requirement of the wire harness, wire harnesses with different diameters can smoothly pass through the wire clamping hole, and sufficient space is reserved inside the wire clamping hole, so that the wire harness will not be excessively squeezed or deformed when passing through.

[0022] In some embodiments, the housing includes a guiding part, the guiding part is connected to the outside of the end cover part, the wire clamping hole penetrates through the guiding part, the wire clamping hole includes a first section hole located in the guiding part, and the width of the first section hole gradually becomes smaller along the direction of the guiding part approaching the end cover part.

[0023] In this way, by providing a guiding part on the housing, the position of the wire harness in the accommodation cavity can be guided, so that the wire harness is fixed.

[0024] In some embodiments, the sheath includes a sealing gasket, the sealing gasket is fixed on the inner wall of the accommodation cavity, and the sealing gasket is provided with a perforation for the wire harness to pass through.

[0025] In this way, by providing a sealing gasket on the inner wall of the accommodation cavity and the wire harness can pass through the perforation on the sealing gasket, the wire harness can be sealed in the accommodation cavity.

[0026] In some embodiments, the sheath further includes a wiring terminal located in the accommodation cavity, one end of the sheath away from the housing is provided with a jack, the jack communicates with the accommodation cavity, and one end of the wiring terminal is arranged close to the jack.

[0028] In some embodiments, the wiring terminal includes a terminal insertion part, a terminal holding part and a wiring part, and the terminal insertion part, the terminal holding part and the wiring part are sequentially connected along the direction away from the jack.

[0029] In this way, the terminal insertion part can achieve a tight connection with the wire harness in the form of pins or sockets, ensuring the smooth transmission of current or signals. The terminal holding part can be responsible for fixing the terminal insertion part to prevent it from loosening or falling off due to factors such as vibration and external forces during operation. Through the wiring part, the electrical energy or signals of the wire harness can be smoothly transmitted to the terminal block.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in

[0048] A connector 10 in an embodiment of this application is used for a vehicle 100. The connector 10 includes a sheath 11 and a housing 12. Among them, the sheath 11 is provided with a receiving cavity 111; the housing 12 includes a fixed cover portion 121, a connecting portion 122 and a tail cover portion 123, and the fixed cover portion 121 is connected to the tail cover portion 123 through the connecting portion 122; when the sheath 11 is connected to the housing 12, the fixed cover portion 121 and the connecting portion 122 are located in the receiving cavity 111.

[0049] Among them, the vehicle 100 includes a wire harness 20. The wire harness 20 can be used to transmit current or signals, thereby serving as a bridge for communication connection between various components of the vehicle 100. Due to different diameter sizes among the wire harnesses 20, it is necessary to set connectors 10 for connection to achieve signal exchange between the wire harnesses 20.

[0050] Specifically, the connector 10 includes a sheath 11 and a housing 12. Among them, the sheath 11 is a cylindrical structure formed by connecting two cylinders together, and a receiving cavity 111 is provided inside the sheath 11. The receiving cavity 111 can be used to accommodate the wire harness 20 and part of the housing 12. The sheath 11 can be movably connected to the housing 12, so that the wire harness 20 can be installed in the sheath 11 and the housing 12.

[0051] The housing 12 includes a fixed cover part 121, a connecting part 122 and a tail cover part 123. Among them, the connecting part 122 is used to connect the fixed cover part 121 and the tail cover part 123, and when the wire harness 20 is not inserted, the tail cover part 123 and the fixed cover part 121 are arranged in a positional relationship greater than 90°. The connecting part 122 is a U-shaped structure, and the U-shaped connecting part 122 can be bent, so that the fixed cover part 121 can perform a pitching motion towards the tail cover part 123 through the connecting part 122. That is, when installing the wire harness 20, the connecting part 122 can make the fixed cover part 121 move closer to the tail cover part 123; when removing the wire harness 20 or when the wire harness 20 is not installed, the connecting part 122 can make the fixed cover part 121 move away from the tail cover part 123.

[0052] When the sheath 11 is connected to the housing 12, the fixed cover part 121 and the connecting part 122 can be located in the receiving cavity 111, that is, the fixed cover part 121 can be fixed to the sheath 11, and at the same time the tail cover part 123 can be fixed to the sheath 11.

[0053] Please refer to Figure 3 、 Figure 4 and Figure 5 , in some embodiments, the tail cover part 123 is provided with a receiving cavity 1231, the sheath 11 is provided with a plurality of first locking parts 112, the tail cover part 123 is provided with a plurality of second locking parts 1232. The first locking parts 112 are evenly distributed on the end face of the sheath 11 close to the opening of the receiving cavity 111, and the second locking parts 1232 are evenly distributed on the end face of the tail cover part 123 close to the opening of the receiving cavity 1231. Each first locking part 112 is locked with a corresponding second locking part 1232.

[0054] In this way, by providing the first locking parts 112 on the sheath 11, providing the second locking parts 1232 on the tail cover part 123, and the first locking parts 112 can cooperate with the second locking parts 1232 to lock, so that the sheath 11 can be fixed to the tail cover part 123.

[0055] Specifically, the shape of the tail cover part 123 is a gun body structure, and an accommodation cavity 1231 is formed inside the tail cover part 123, and the accommodation cavity 1231 can be used to accommodate the wire harness 20. A first locking part 112 is arranged on the sheath 11, and the number of the first locking parts 112 can be multiple. For example, the number of the first locking parts 112 is 2, 3, etc. The multiple first locking parts 112 are evenly distributed on the end face of the sheath 11 close to the orifice of the accommodation cavity 111. The first locking part 112 can be a first snap head 1121, and the shape of the first snap head 1121 can be a frustum protruding from the outer side of the sheath 11.

[0056] A second locking part 1232 is arranged on the tail cover part 123. The number of the second locking parts 1232 can be multiple and corresponds to the number of the first locking parts 112. For example, when the number of the first locking parts 112 is 2, the number of the second locking parts 1232 is 2; when the number of the first locking parts 112 is 3, the number of the second locking parts 1232 is 3. The multiple second locking parts 1232 are evenly arranged on the end face of the tail cover part 123 close to the orifice of the accommodation cavity 1231. The second locking part 1232 can be a first snap groove 12321, and the shape of the first snap groove 12321 is adapted to the shape of the first snap head 1121, so that the first snap groove 12321 can be set to be engaged with the first snap head 1121, so that each first locking part 112 can be locked with a second locking part 1232, and further the sheath 11 and the housing 12 are fixed. In this way, the shapes of the first snap head 1121 and the first snap groove 12321 match. When the first snap head 1121 enters the first snap groove 12321, the tightness and stability of the sheath 11 and the tail cover part 123 can be increased.

[0057] Please refer to Figure 4 and Figure 5 , in some embodiments, the sheath 11 is provided with a plurality of third locking parts 113, and the fixed cover part 121 is provided with a plurality of fourth locking parts 1212. The third locking parts 113 are evenly distributed on the inner wall of the accommodation cavity 111, and the fourth locking parts 1212 are evenly distributed on the periphery of the fixed cover part 121. Each third locking part 113 is locked with a corresponding fourth locking part 1212.

[0058] In this way, by providing the third locking part 113 on the sheath 11, providing the fourth locking part 1212 on the fixed cover part 121, and the third locking part 113 can cooperate with the fourth locking part 1212 to lock, so that the sheath 11 can be fixed to the fixed cover part 121.

[0059] Specifically, a third locking portion 113 is provided on the sheath 11. The number of the third locking portions 113 can be multiple. For example, the number of the third locking portions 113 can be 2, 3, etc. The multiple third locking portions 113 can be evenly distributed around the inner wall of the accommodating cavity 111. The third locking portion 113 can be a second buckle groove 1131.

[0060] A fourth locking portion 1212 is provided on the fixed cover portion 121. The number of the fourth locking portions 1212 can be multiple and corresponds to the number of the third locking portions 113. For example, when the number of the third locking portions 113 is 2, the number of the fourth locking portions 1212 is 2; when the number of the third locking portions 113 is 3, the number of the fourth locking portions 1212 is 3. The multiple fourth locking portions 1212 are evenly distributed on the circumferential side of the fixed cover portion 121. The fourth locking portion 1212 can be a second buckle head 12121 and an elastic hole 12122. The shape of the second buckle head 12121 is adapted to the shape of the second buckle groove 1131. The shape of the elastic hole 12122 is semi-circular. And the second buckle head 12121 is provided on the side of the fixed cover portion 121. The elastic hole 12122 is located between the side and the center of the fixed cover portion 121 and close to the second buckle head 12121. The elastic hole 12122 can generate elastic deformation when the second buckle head 12121 is squeezed, so that the second buckle groove 1131 can be engaged with the second buckle head 12121 under the action of the elastic hole 12122, and further the sheath 11 can be fixedly connected to the fixed cover portion 121. The second buckle head 12121 protrudes on the outer side of the fixed cover portion 121, and the second buckle head 12121 is flush with the thickness of the fixed cover portion 121 in the thickness direction. The second buckle head 12121 includes a guiding surface, and its guiding angle is within 30°.

[0061] In this way, by providing the elastic hole 12122 on the side of the second buckle head 12121, the second buckle head 12121 can be easily elastically deformed. The shapes of the second buckle head 12121 and the second buckle groove 1131 match. When the first buckle head 1121 enters the first buckle groove 12321, the tightness and stability between the sheath 11 and the end cover portion 123 can be increased.

[0062] It should be noted that the length of the elastic hole 12122 is greater than the length of the second buckle head 12121. In this way, by setting the length of the elastic hole 12122 to be greater than the length of the second buckle head 12121, it is beneficial for the second buckle head 12121 to elastically deform, reduce the wear of the second buckle head 12121, and reduce the risk of the fixed cover portion 121 falling off.

[0063] In some embodiments, a wire insertion hole 1211 is further formed in the fixed cover portion 121, and the size of the wire insertion hole 1211 is adapted to the diameter of the wire harness 20, so that the wire harness 20 can pass through the wire insertion hole 1211.

[0064] Please refer to Figure 5 and Figure 6 , in some embodiments, the fixed cover portion 121, the connecting portion 122, and the tail cover portion 123 are of an integral structure.

[0065] In this way, by designing the fixed cover portion 121, the connecting portion 122, and the tail cover portion 123 as an integral structure, the housing 12 can be assembled without being separated during assembly, reducing the number of assembly personnel involved, reducing the waste of human resources, and improving the assembly efficiency.

[0066] Specifically, the fixed cover portion 121, the connecting portion 122, and the tail cover portion 123 can be made by a casting process or an injection molding process. For example, molten plastic is injected into the housing 12 mold by an injection molding machine, and after cooling, an integral structure of the fixed cover portion 121, the connecting portion 122, and the tail cover portion 123 can be formed.

[0067] Please refer to Figure 5 and Figure 6 , in some embodiments, the tail cover portion 123 is provided with a receiving cavity 1231, and the tail cover portion 123 includes a wire clamping hole 1233 which is arranged on the side surface of the tail cover portion 123 and communicates with the receiving cavity 1231.

[0068] In this way, by providing the wire clamping hole 1233 on the side surface of the tail cover portion 123, the wire clamping hole 1233 can communicate with the receiving cavity 1231, so that the wire harness 20 in the vehicle 100 can enter the receiving cavity 1231 through the wire clamping hole 1233.

[0069] Specifically, the tail cover portion 123 further includes a wire clamping hole 1233 which can be used to limit the position of the wire harness 20. The number of the wire clamping holes 1233 can be multiple. For example, the number of the wire clamping holes 1233 can be 2, 3, etc. The multiple wire clamping holes 1233 are arranged in sequence along the axis of the housing 12 on the outer side surface of the housing 12. The wire clamping hole 1233 can communicate with the receiving cavity 1231, so that the wire harness 20 can enter the receiving cavity 1231 through the wire clamping hole 1233.

[0070] Please refer to Figure 6 , in some embodiments, the gap of the wire clamping hole 1233 is smaller than the minimum wire diameter of the crimped wire harness 20, and the inner hanging size of the wire clamping hole 1233 is larger than the maximum wire diameter requirement of the wire harness 20.

[0071] Thus, by setting the gap of the wire clamping hole 1233 to be smaller than the minimum wire diameter for the crimping of the wire harness 20, it is possible to prevent the wire harness 20 from detaching from the accommodation cavity 1231 under external force after the wire harness 20 enters the accommodation cavity 1231. By making the inner hanging size of the wire clamping hole 1233 larger than the maximum wire diameter required for the wire harness 20, wire harnesses 20 with different diameters can smoothly pass through the wire clamping hole 1233, and sufficient space is reserved inside the wire clamping hole 1233 so that the wire harness 20 will not be overly squeezed or deformed when passing through.

[0072] Specifically, the shape of the wire clamping hole 1233 is hourglass-shaped. As Figure 6 shown, the diameters at both ends of the wire clamping hole 1233 are larger than the diameter of the middle part, and it is necessary to make the interval L1 of the wire clamping hole 1233 smaller than the minimum crimping wire diameter of the crimped wire harness 20, that is, the diameter of the middle part of the wire clamping hole 1233 is smaller than the wire diameter of the wire harness 20 entering the accommodation cavity 1231. Thus, when crimping the wire harness 20, the wire harness 20 can undergo elastic deformation under the action of external force, so that the wire harness 20 passes through the wire clamping hole 1233 and enters the accommodation cavity 1231, and when the wire harness 20 is not under the action of external force, it cannot detach from the accommodation cavity 1231 through the wire clamping hole 1233.

[0073] As Figure 6 shown, the inner hanging size L2 of the wire clamping hole 1233 is larger than the maximum wire diameter required for the wire harness 20, that is, the diameters at both ends of the wire clamping hole 1233 need to be larger than the maximum wire diameter of the wire harness 20, so that the wire diameter can enter the wire clamping hole 1233.

[0074] Please refer to Figure 5 and Figure 6 , in some embodiments, the housing 12 includes a guiding portion 124. The guiding portion 124 is connected to the outside of the end cap portion 123, the wire clamping hole 1233 penetrates through the guiding portion 124, and the wire clamping hole 1233 includes a first-stage hole 12331 located in the guiding portion 124. The width of the first-stage hole 12331 gradually decreases along the direction of the guiding portion 124 approaching the end cap portion 123.

[0075] Thus, by providing the guiding portion 124 on the housing 12, the position of the wire harness 20 in the accommodation cavity 1231 can be guided, so that the wire harness 20 is fixed.

[0076] Specifically, the outer shell 12 further includes a guiding portion 124. The guiding portion 124 protrudes from the outer side of the end cap portion 123 and is disposed near the port of the end cap portion 123. The number of the guiding portions 124 can be multiple. For example, the number of the guiding portions 124 can be 2, 3, etc. The multiple guiding portions 124 can be arranged in sequence along the axis of the end cap portion 123. The guiding portion 124 can guide the wire harness 20 in the vertical direction when the wire harness 20 enters the accommodating cavity 1231.

[0077] The wire clamping hole 1233 can be arranged through the guiding portion 124, so that the wire harness 20 can pass through the wire clamping hole 1233 and the guiding portion 124, and thus the wire harness 20 entering the accommodating cavity 1231 is guided in the vertical direction. The wire clamping hole 1233 includes a first-stage hole 12331. The first-stage hole 12331 is located on the guiding portion 124, and the width of the first-stage hole 12331 gradually decreases along the direction of the guiding portion 124 approaching the end cap portion 123, so as to meet the requirement that the gap of the wire clamping hole 1233 is smaller than the minimum wire diameter of the crimped wire harness 20 and the inner hanging size of the wire clamping hole 1233 is larger than the maximum wire diameter required by the wire harness 20.

The terminal 115 is arranged at one end of the accommodation cavity 111 away from the cavity opening and is used to connect with the wire harness 20 extending into the accommodation cavity 111. Wherein, one end of the sheath 11 facing away from the housing 12 is provided with a jack, and the jack can communicate the accommodation cavity 111 with the outside, so that the external wire harness 20 can be inserted into the jack. One end of the terminal 115 can be arranged close to the jack, so that the external wire harness 20 can be connected to the terminal 115 through the jack.

[0084] The terminal 115 includes a terminal insertion part 1151, a terminal holding part 1152 and a wiring part 1153. The terminal insertion part 1151, the terminal holding part 1152 and the wiring part 1153 are sequentially connected in a direction away from the jack. Among them, the terminal insertion part 1151 can be connected to the wire harness 20 inserted through the jack; the wiring part 1153 can be connected to the wire harness 20 inserted into the accommodation cavity 111 through the through hole 1141; the terminal holding part 1152 can connect the terminal insertion part 1151 and the wiring part 1153, so that the wire harness 20 inserted into the jack can be connected to the wire harness 20 passing through the through hole 1141.

[0085] In this way, the terminal insertion part 1151 can achieve a tight connection with the wire harness 20 in the form of a pin or a jack, ensuring the smooth transmission of current or signals. The terminal holding part 1152 can be responsible for fixing the terminal insertion part 1151 to prevent it from loosening or falling off due to factors such as vibration and external force during operation. By connecting with other wire harnesses 20 through the wiring part 1153, the electrical energy or signals of the wire harness 20 can be smoothly transmitted to the terminal 115.
