Description

Technical Field

[0001] This application relates to the field of connector technology, and more specifically to a connector assembly. Background Technology

[0002] With the increasing intelligence of vehicles, the number of devices installed on them is also increasing, requiring a large number of connector assemblies to achieve high-speed data transmission and reliable electrical connections between these devices. Connector assemblies typically include male and female connectors, which are plugged together during use. Due to the limited interior space of vehicles, the assembly space is narrow, leading to severe bending of the wiring harness during vehicle assembly and maintenance, resulting in high internal stress. When the male and female connectors are plugged in, an oblique insertion phenomenon may occur. This not only increases the resistance during insertion, making it difficult for personnel to operate, but also causes the sealing ring between the male and female connectors to be broken or flipped, leading to seal failure of the connector assembly and safety issues. Utility Model Content

[0003] This application provides a connector assembly that not only reduces the resistance when the male and female connectors are inserted, making it easier for personnel to operate, but also prevents the seal between the male and female connectors from being broken or flipped, thereby ensuring the sealing performance of the connector assembly.

[0004] This application provides a connector assembly, including:

[0005] A male connector, comprising a male housing and a male power terminal, wherein at least a portion of the male power terminal is accommodated within a first cavity of the male housing;

[0006] A female connector includes a female housing and a female power terminal, at least a portion of which is housed in a second cavity of the female housing. One end of the female power terminal is used to connect to a male power terminal, and the other end of the female power terminal is used to connect to a wire.

[0007] The male terminal housing has at least one male terminal guide portion, which is located near the corner of the male terminal housing. The female terminal housing has at least one female terminal guide portion that mates with the male terminal guide portion, which is located near the corner of the female terminal housing. The male terminal guide portion and the female terminal guide portion work together to guide the male terminal connector to be inserted into the female terminal connector.

[0008] Beneficial Effects: Compared with the prior art, the connector assembly provided in this application includes a male connector and a female connector. The male connector has a male guide portion at the corner of its male housing, and the female connector has a female guide portion at the corner of its female housing that mates with the male guide portion. The male and female guide portions cooperate to guide the male and female connectors into contact. In other words, when the male and female connectors are inserted at an angle, the male and female guide portions cooperate to correct the insertion direction, thereby reducing the angle of insertion and even ensuring that the insertion directions remain coaxial. This not only reduces the resistance during insertion, facilitating operation, but also prevents the seal between the male and female connectors from being broken or flipped, thus ensuring the sealing performance of the connector assembly. In addition, it can reduce wear between the male and female housings, thereby extending the service life of the connector assembly. It can also ensure the alignment between the male and female power terminals, thereby ensuring the stability of the connection between the male and female power terminals.

[0020] This application provides a connector assembly, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0021] Reference Figure 1 and Figure 2 One embodiment of this application provides a connector assembly, including a male connector 1 and a female connector 2. In use, the male connector 1 and the female connector 2 are plugged into each other.

[0022] Reference Figures 1 to 3 The male connector 1 may include a male housing 11 and a male power terminal 12, at least a portion of which may be accommodated within a first cavity 111 of the male housing 11. The male housing 11 may be made of plastic, and the male power terminal 12 may be made of conductive material, with at least a portion of the male power terminal 12 mounted within the first cavity 111.

[0023] In this embodiment, one end of the male power terminal 12 protrudes from the side of the male housing 11 facing the female housing 21, and the other end of the male power terminal 12 protrudes from the side of the male housing 11 facing away from the female housing 21. Preferably, the number of first cavities 111 and the number of male power terminals 12 are the same. Both the number of first cavities 111 and the number of male power terminals 12 can be two, with two male power terminals 12 respectively disposed in two first cavities 111, so that the two male power terminals 12 are spaced apart from each other.

[0024] Reference Figures 1 to 3 as well as Figure 6 and Figure 7 The female connector 2 may include a female housing 21 and a female power terminal 22, with at least a portion of the female power terminal 22 housed within a second cavity 211 of the female housing 21. One end of the female power terminal 22 is used to connect to the male power terminal 12, and the other end of the female power terminal 22 is used to connect to a wire 6 to achieve power or signal transmission. The female housing 21 may be made of plastic, and the female power terminal 22 may be made of conductive material, with at least a portion of the female power terminal 22 mounted within the second cavity 211.

[0025] In this embodiment, the number of second cavities 211 and the number of female power terminals 22 are preferably the same. Both the number of second cavities 211 and the number of female power terminals 22 can be two, with each of the two female power terminals 22 correspondingly disposed in one of the two second cavities 211, spaced apart from each other. The female power terminals 22 are completely disposed within the second cavities 211, and one end of the wire 6 can be inserted into the second cavity 211 and connected to the female power terminal 22. When the male connector 1 and the female connector 2 are engaged, the male power terminal 12 can be inserted into the second cavity 211 and connected to the female power terminal 22.

[0026] Reference Figure 3 A first seal 23 may also be provided between the male connector 1 and the female connector 2. The first seal 23 ensures a sealed connection between the male connector 1 and the female connector 2. The first seal 23 can improve the sealing performance of the connector assembly, thereby improving the waterproof performance of the connector assembly. The first seal 23 may be made of an elastic material, such as silicone, to improve the sealing effect of the first seal 23.

[0027] Reference Figures 4 to 7The male end housing 11 facing the female end housing 21 can be polygonal, such as quadrilateral, and the female end housing 21 facing the male end housing 11 can also be polygonal, such as quadrilateral. The male end housing 11 may have at least one male end guide portion 112, located near a corner of the male end housing 11. The female end housing 21 has at least one female end guide portion 212 that mates with the male end guide portion 112, located near a corner of the female end housing 21. The male end guide portion 112 and the female end guide portion 212 cooperate to guide the male end connector 1 and the female end connector 2 to insert. In other words, when the male connector 1 and the female connector 2 are inserted at an angle, the male guide portion 112 located at the corner of the male housing 11 and the female guide portion 212 located at the corner of the female housing 11 cooperate, not only providing guidance but also correcting the insertion direction of the male connector 1 and the female connector 2. This reduces the angle of insertion and can even keep the insertion directions of the male connector 1 and the female connector 2 coaxial. This not only reduces the resistance during insertion, facilitating operation, but also prevents the first seal 23 between the male connector 1 and the female connector 2 from being broken or flipped, thus ensuring the sealing performance of the connector assembly. Furthermore, it reduces wear between the male housing 11 and the female housing 21, extending the service life of the connector assembly. It also ensures alignment between the male power terminal 12 and the female power terminal 22, thereby ensuring the stability of the connection between the male power terminal 12 and the female power terminal 22. If the male guide portion 112 is only provided on the side of the male housing 11 and the female guide portion 212 is only provided on the side of the female housing 21, the male guide portion 112 and the female guide portion 212 only have a guiding function and cannot correct the insertion direction of the male connector 1 and the female connector 2.

[0028] Reference Figures 4 to 7 The male end guide portion 112 can be a protruding rib extending in the mating direction, and the female end guide portion 212 can be a groove extending in the mating direction. Alternatively, the male end guide portion 112 can be a groove extending in the mating direction, and the female end guide portion 212 can be a protruding rib extending in the mating direction. Alternatively, when there are multiple male end guide portions 112 and female end guide portions 212, some male end guide portions 112 can be protruding ribs extending in the mating direction, some male end guide portions 112 can be grooves extending in the mating direction, some female end guide portions 212 correspond to grooves extending in the mating direction, and some female end guide portions 212 correspond to protruding ribs extending in the mating direction. When the male end connector 1 and the female end connector 2 are inserted at an angle, the protruding rib can move in the groove along the mating direction.

[0029] In this embodiment, refer to Figure 4 and Figure 5 The male end housing 11 has multiple male end guide portions 112 on the side facing the female end housing 21. Some of the male end guide portions 112 are located on the side of the male end housing 11, and some are located at the corners of the male end housing 11. (Refer to...) Figure 6 and Figure 7 The female end housing 21 has multiple female end guides 212 on the side facing the male end housing 11. Some of the female end guides 212 are located on the side of the female end housing 21, and some are located at the corners of the female end housing 21. This not only corrects the insertion direction of the male end connector 1 and the female end connector 2, but also improves the guiding function of the male end guides 112 and the female end guides 212.

[0030] Reference Figure 2 The male end housing 11 may be provided with a first fixing part 116, and the female end housing 21 may be provided with a second fixing part 216. The first fixing part 116 and the second fixing part 216 can be connected by a first connector 3, that is, the first connector 3 is simultaneously engaged with the first fixing part 116 and the second fixing part 216, thereby ensuring the stability of the connection between the male end connector 1 and the female end connector 2. The first connector 3 can be fixed to the female end housing 21 by a second connector 4 to ensure the stability of the position of the first connector 3.

[0031] In one specific implementation, refer to Figure 1 and Figure 2 as well as Figures 4 to 7 The male guide portion 112 may include a first male guide portion 1121 and a second male guide portion 1122, and the female guide portion 212 may include a first female guide portion 2121 and a second female guide portion 2122. The first male guide portion 1121 and the first female guide portion 2121 cooperate with each other, and the second male guide portion 1122 and the second female guide portion 2122 cooperate with each other. When the male connector 1 and the female connector 2 are inserted, the first male guide portion 1121 and the first female guide portion 2121 contact each other before the second male guide portion 1122 and the second female guide portion 2122. That is, when the male connector 1 and the female connector 2 begin to insert, the first male guide portion 1121 and the first female guide portion 2121 begin to contact each other, and as the male connector 1 and the female connector 2 are inserted deeper, the second male guide portion 1122 and the second female guide portion 2122 begin to contact each other.

[0032] Specifically, refer to Figures 4 to 7The ends of the first female end guide 2121 and the second female end guide 2122 facing the male end housing 11 can be on the same horizontal plane, that is, the distances from the ends of the first female end guide 2121 and the second female end guide 2122 facing the male end housing 11 to the male end housing 11 are equal or approximately equal. The first male end guide 1121 can be disposed at the end of the male end housing 11 close to the female end housing 21, and the second male end guide 1122 can be disposed at the end of the male end housing 11 away from the female end housing 21, so that the first male end guide 1121 and the first female end guide 2121 contact the second male end guide 1122 and the second female end guide 2122 first.

[0033] The length of the first male guide portion 1121 can be greater than the length of the second male guide portion 1122, and the length of the first female guide portion 2121 can be greater than the length of the second female guide portion 2122. The length of the first male guide portion 1121 is equal to or approximately equal to the length of the first female guide portion 2121, and the length of the second male guide portion 1122 is equal to or approximately equal to the length of the second female guide portion 2122. During the mating process of the male connector 1 and the female connector 2, the first male guide portion 1121 and the first female guide portion 2121 contact first, which can achieve initial alignment. After the male connector 1 and the female connector 2 have been mated for a certain distance, the second male guide portion 1122 and the second female guide portion 2122 contact later, which can further improve the alignment effect.

[0034] The first male end guide portion 1121 and the second male end guide portion 1122 can be respectively disposed on opposite sides of the male end housing 11, that is, the first male end guide portion 1121 and the second male end guide portion 1122 can be symmetrically disposed. The first female end guide portion 2121 and the second female end guide portion 2122 can be respectively disposed on opposite sides of the female end housing 21, that is, the first female end guide portion 2121 and the second female end guide portion 2122 can be symmetrically disposed.

[0035] As an example, refer to Figures 4 to 7The male end housing 11 is provided with five first male end guides 1121 and five second male end guides 1122. Three first male end guides 1121 are located on one side of the male end housing 11, and the other two first male end guides 1121 are located at two adjacent corners. Three second male end guides 1122 are located on the opposite side of the male end housing 11, and the other two second male end guides 1122 are located at two adjacent corners. The female end housing 21 is provided with five first female end guides 2121 and five second female end guides 2122. Three first female end guides 2121 are located on one side of the female end housing 21, and the other two first female end guides 2121 are located at two adjacent corners. Three second female end guides 2122 are located on the opposite side of the female end housing 21, and the other two second female end guides 2122 are located at two adjacent corners.

[0036] As a preferred method, refer to Figures 4 to 7 The first cavity 111 has a first sidewall 113 at the end facing the male end housing 11. A second sidewall 114 can be provided on the outer side of the first sidewall 113. The male end guide portion 112 can be provided on the second sidewall 114. The first sidewall 113 and the second sidewall 114 surround to form a third cavity 115. The second sidewall 114 can connect multiple male end guide portions 112 together, which can enhance the structural strength of the male end guide portions 112.

[0037] The second cavity 211 has a third sidewall 213 at the end facing the female end shell 21. A fourth sidewall 214 can be provided on the outer side of the third sidewall 213. The female end guide portion 212 can be provided on the fourth sidewall 214. The third sidewall 213 and the fourth sidewall 214 surround to form a fourth cavity 215. The fourth sidewall 214 can connect multiple female end guide portions 212 together, which can enhance the structural strength of the female end guide portions 212.

[0038] When the male connector 1 and the female connector 2 are engaged, at least a portion of the first sidewall 113 is inserted into the second cavity 211, at least a portion of the second sidewall 114 is inserted into the fourth cavity 215, and at least a portion of the third sidewall 213 is inserted into the third cavity 115.

[0039] Reference Figures 3 to 7 A first seal 23 may be provided at the end of the third sidewall 213 facing the male end housing 11. When the male end connector 1 is inserted with the female end connector 2, at least a portion of the first seal 23 is located between the third sidewall 213 and the second sidewall 114. The first seal 23 can improve the sealing of the connector assembly to improve the waterproof performance of the connector assembly.

[0040] In one specific implementation, refer to Figure 3 , Figure 6 and Figure 7 The female connector 2 may further include an inner shell 24, a first shielding cover 25, a shielding sleeve 26, a second seal 27, and an end cap 28. The inner shell 24 can be installed inside the first cavity 111, and the female power terminal 22 can be disposed on the inner shell 24. The first shielding cover 25 can be sleeved on the outside of the inner shell 24 and connected to the shielding sleeve 26. The first shielding cover 25 and the shielding sleeve 26 can be connected by abutment, snap-fit, or other means. The shielding sleeve 26, the second seal 27, and the end cap 28 can be sleeved on the wire 6. The second seal 27 can improve the sealing performance of the connector assembly. The end cap 28 can be disposed on the outside of the second seal 27 and snap-fitted with the female outer shell 21. The end cap 28 can ensure the stability of the position of the second seal 27 and prevent the second seal 27 from falling off the female outer shell 21.

[0041] The shielding sleeve 26 can be disposed in the second cavity 211, that is, the shielding sleeve 26 can be sleeved on one end of the wire 6 located inside the second cavity 211. The shielding sleeve 26 can be connected to the shielding layer (not shown) in the wire 6 and the first shielding cover 25 respectively. The first shielding cover 25 can be connected to the shielding layer in the wire 6 through the shielding sleeve 26. The shielding layer can discharge the interference signal, for example, guide the interference signal to the grounding terminal.

[0042] The shielding sleeve 26 may include a first shielding sleeve 261 and a second shielding sleeve 262. The second shielding sleeve 262 may be fitted over the outside of the first shielding sleeve 261. The shielding layer of the wire 6 may be disposed between the first shielding sleeve 261 and the second shielding sleeve 262. The first shielding sleeve 261 and the second shielding sleeve 262 may clamp the shielding layer of the wire 6 together, thereby ensuring the stability of the connection between the shielding layer and the shielding sleeve 26.

[0043] Reference Figures 3 to 5 The male connector 1 may also include a second shield 13. The second shield 13 may be disposed on the outside of the male power terminal 12. When the male connector 1 is inserted with the female connector 2, the first shield 25 may be connected to the second shield 13. The first shield 25 and the second shield 13 may be connected by abutting, snapping or other means. The second shield 13 may discharge interference signals through the first shield 25.

[0045] Reference Figure 1 A bushing 142 may also be provided inside the mounting hole 141. The bushing 142 may be annular in shape, and the material of the bushing 142 may be metal or non-metal. In this embodiment, the bushing 142 is made of metal material. The metal bushing 142 can distribute the tightening force of the screw and prevent the male end shell 11 made of plastic or soft material from cracking or deforming due to excessive force.

[0046] A third seal 15 is provided on the side of the mounting panel 14 facing away from the female end housing 21. When the mounting panel 14 is installed on other equipment, the third seal 15 is located between the mounting panel 14 and other equipment. The third seal 15 may be made of an elastic material, such as silicone, to improve the sealing effect of the third seal 15.

[0047] In some embodiments, refer to Figure 3 The connector assembly may also include a high-voltage interlock terminal 5, which can be connected to an external high-voltage interlock signal control element (not shown) to achieve a high-voltage interlock function.
