Description

Technical Field

[0001] This application relates to connectors, and more particularly to a terminal assembly and connector capable of providing signal integrity in harsh environments. The aforementioned connector may be a 5G high-speed connector. Background Technology

[0002] Electrical connectors are commonly used in electronic systems. Generally, manufacturers modularize electronic systems to form multiple independent electronic components, and then connect these independent electronic components together using electrical connectors, enabling the individual electronic components to work together.

[0003] Electrical connectors include board connectors mounted on printed circuit boards (PCBs) and cable connectors that mate with those board connectors. In some electronic systems, connecting two PCBs by mating their board connectors can be difficult. For example, when assembling an electronic system, the distance between the board connectors of two PCBs may be too large, making mating difficult.

[0004] In some electronic systems, electronic components can be connected via cables. The ends of these cables are equipped with cable connectors that mate with board connectors, allowing the electronic system to be plugged into the board connectors of the printed circuit board, thus achieving the connection between electronic components. In other electronic systems, electrical connections can be achieved by using two cables, with their cable connectors interlocking.

[0005] The aforementioned cables can be used to connect various electronic components in automated vehicles, such as electronic control units (ECUs), engines, transmissions (TCUs), safety systems, emission control systems, lighting systems, advanced driver assistance systems (ADAS), entertainment systems, navigation systems, and cameras. These electronic components can be manufactured in a modular fashion, and the modularly manufactured electronic components are connected by cables to achieve electrical connections between the individual electronic components.

[0006] Because vehicles operate in harsh environments, vibrations can cause cable connectors to loosen, leading to malfunctions in the electronic components connected to them. Secondly, even if vehicle vibrations don't cause loose connectors, they can still generate electrical noise in the electronic components, interfering with their operation. For example, electrical noise might be caused by the relative movement of components within the cable connector. This relative movement can alter the connector's electrical characteristics, which in turn can change the signals passing through the connector, thus interfering with underlying signals.

[0007] In the vehicle operating environment, electrical noise can also originate from electromagnetic radiation generated by vehicle components. This radiation can couple to the conductive structure of cable connectors, thereby generating noise on any signal passing through the conductive structure. Many vehicle components can generate electromagnetic radiation, such as spark plugs, alternators, or power switches. Furthermore, electrical noise is particularly problematic for high-speed signals, such as vehicle network signals. Utility Model Content

[0069] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0070] The inventors of this application have recognized techniques for manufacturing connectors and the structures of connectors that provide high data rate transmission, are low in manufacturing cost, and can operate reliably in the harsh environments of automobiles. Such connectors are suitable for interconnecting components in automotive networks. For example, these techniques can be applied to modular connector systems.

[0071] Figure 1 This diagram shows a structural schematic of the terminal assembly 10 according to this application. Figure 2 An exploded view of the terminal assembly 10 according to this application is shown. Figure 3 This shows a schematic diagram of the structure of terminal 200 according to this application. Figure 4 A side view of the terminal assembly 10 according to this application is shown. Figure 5 Show Figure 4 See the sectional view of AA. Figures 1 to 5 This application provides a terminal assembly 10, which may include a housing 100 and at least one terminal 200.

[0072] See Figures 1 to 3 The terminal 200 includes a terminal body 201, on which a first limiting structure 202 and a second limiting structure 203 are provided. The terminal body 201 has a plug interface 201a and a mounting port 201b. The plug interface 201a is used to connect a plug pin, and the mounting port 201b is used to connect a cable 70.

[0073] See Figure 1The housing 100 defines a cavity 101, a first limiting engagement structure 102, and a second limiting engagement structure 103. The terminal body 201 is accommodated within the cavity 101, and the first limiting structure 202 and the second limiting structure 203 are respectively disposed on the outer wall surface of the terminal body 201.

[0074] For example, the terminal body 201 may be generally cylindrical, and the first limiting structure 202 and the second limiting structure 203 are spaced apart along the circumferential direction of the cylindrical terminal body 201.

[0075] The first limiting structure 202 cooperates with the first limiting engagement structure 102 to prevent the terminal 200 from moving relative to the housing 100, at least in the longitudinal direction X. The second limiting structure 203 cooperates with the second limiting engagement structure 103 to prevent the terminal 200 from rotating relative to the housing 100, at least in the direction surrounding the longitudinal direction X.

[0076] In the following description of this application specification, the longitudinal direction X can be the extension direction of the terminal assembly 10, the transverse direction Y can be the direction perpendicular to the extension direction of the terminal assembly 10, and the vertical direction Z is the direction perpendicular to the extension direction of the terminal assembly 10. The longitudinal direction X, the transverse direction Y, and the vertical direction Z are perpendicular to each other.

[0077] According to one embodiment of the present application, the terminal assembly 10, compared with the related art scheme that only sets a pair of protrusions and grooves to achieve mutual locking of the housing 100 and the terminal 200, the present application uses a first limiting structure 202 to cooperate with a first limiting cooperation structure 102, and a second limiting structure 203 to cooperate with a second limiting cooperation structure 103, thereby preventing relative movement between the terminal 200 and the housing 100 in the longitudinal X and circumferential directions around the longitudinal X. Compared with the related art, the present application can further reduce the loosening and displacement of the terminal 200 during use, thereby ensuring the stability of the electrical connection of the terminal 200, and enabling the terminal assembly 10 to provide a reliable electrical connection in various usage environments.

[0078] In this embodiment, the first limiting structure 202 can be a protrusion structure or a groove structure, and the first limiting mating structure 102 can be a groove structure or a protrusion structure that can form a snap-fit ​​with the first limiting structure 202.

[0079] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the first limiting structure 202 can be a protrusion structure, and the first limiting mating structure 102 can be a groove structure. At least a portion of the first limiting structure 202 extends into the first limiting mating structure 102 so that the two form a snap-fit ​​engagement.

[0080] In this embodiment, at least a portion of the first limiting structure 202 extends into the first limiting mating structure 102, and at least a portion of the second limiting structure 203 extends into the second limiting mating structure 103. By extending the first limiting structure 202 into the first limiting mating structure 102, this application effectively fixes the terminal 200 within the cavity 101, preventing the housing 100 and the terminal 200 from loosening and relative displacement during use.

[0081] In other examples, the first limiting structure 202 may specifically be a groove structure, and the first limiting mating structure 102 may specifically be a protrusion structure, with at least a portion of the protrusion structure extending into the groove structure to form a snap-fit ​​engagement between the two.

[0082] In some embodiments, the second limiting structure 203 may be a protrusion structure or a groove structure, and the second limiting mating structure 103 may be a groove structure or a protrusion structure that can form a snap-fit ​​with the second limiting structure 203.

[0083] In some examples, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the second limiting structure 203 can be a protrusion structure, and the second limiting mating structure 103 can be a groove structure. At least a portion of the second limiting structure 203 extends into the second limiting mating structure 103 so that the two form a snap-fit ​​engagement.

[0084] In this embodiment, at least a portion of the second limiting structure 203 extends into the second limiting mating structure 103. The second limiting structure 203 extends into the second limiting mating structure 103. By extending the second limiting structure 203 into the second limiting mating structure 103, the terminal 200 is effectively fixed in the cavity 101, preventing the housing 100 and the terminal 200 from loosening and relative displacement during use.

[0085] In other examples, the second limiting structure 203 may specifically be a groove structure, and the second limiting mating structure 103 may specifically be a protrusion structure, with at least a portion of the protrusion structure extending into the groove structure to form a snap-fit ​​engagement between the two.

[0086] It is understood that in the embodiments of this application, the first limiting structure 202 and the second limiting structure 203 can both be protruding structures or groove structures, and correspondingly, the first limiting mating structure 102 and the second limiting mating structure 103 can both be groove structures or protruding structures; or, the first limiting structure 202 can be a protruding structure and the second limiting structure 203 can be a groove structure, and correspondingly, the first limiting mating structure 102 can be a groove structure and the second limiting mating structure 103 can be a protruding structure; or, the first limiting structure 202 can be a groove structure and the second limiting structure 203 can be a protruding structure, and correspondingly, the first limiting mating structure 102 can be a protruding structure and the second limiting mating structure 103 can be a groove structure.

[0087] In summary, according to another embodiment of this application, the terminal assembly 10, by providing a first limiting structure 202 and a first limiting fit structure 102 forming a snap-fit, as well as a second limiting structure 203 and a second limiting fit structure 103, can prevent the housing 100 and the terminal 200 from loosening and relative displacement during use.

[0088] It should be noted that, in this application, the first limiting structure 202 and the second limiting structure 203 are preferably protruding structures, and the first limiting mating structure 102 and the second limiting mating structure 103 are groove structures. With this configuration, this application can be engaged with the first limiting structure 202 and the second limiting structure 203 respectively, that is, the two protrusions are engaged with the two locking grooves respectively, thereby achieving the limiting between the housing 100 and the terminal 200. Compared with related technologies, this application can further reduce the loosening and displacement of the terminal 200 during use, thereby ensuring the stability of the electrical connection of the terminal 200 and enabling the terminal assembly 10 to provide a reliable electrical connection in various usage environments.

[0089] The following example illustrates this application by using the first limiting structure 202 and the second limiting structure 203 as protruding structures and the first limiting mating structure 102 and the second limiting mating structure 103 as groove structures.

[0090] In some embodiments, see Figure 1 The first limiting structure 202 includes a first limiting protrusion, and the first limiting mating structure 102 includes a first limiting groove. The first limiting protrusion abuts against the first limiting groove to prevent the terminal 200 from moving relative to the housing 100, at least in the direction from the insertion interface 201a to the mounting port 2011b. The second limiting structure 203 abuts against the second limiting mating structure 103 to prevent the terminal 200 from moving relative to the housing 100, at least in the direction from the mounting port 201b to the insertion interface 201a.

[0091] In some embodiments, the first limiting groove and the second limiting groove are respectively connected to the cavity 101.

[0092] In some embodiments, the second limiting structure 203 includes a second limiting protrusion, and the second limiting mating structure 103 includes a second limiting groove. The second limiting protrusion abuts against at least one side of the second limiting groove in the lateral direction, so that when the terminal 200 has a tendency to rotate, the second limiting protrusion can abut against at least one side of the second limiting groove in the lateral Y direction, thereby preventing the terminal 200 from rotating relative to the housing 100 in the direction surrounding the longitudinal X direction.

[0093] For example, the terminal body 201 is accommodated in the cavity 101. The first limiting structure 202 and the second limiting structure 203 are respectively disposed on the outer wall surface of the terminal body 201. The first limiting structure 202 extends from the cavity 101 into the first limiting fit structure 102, and the second limiting structure 203 extends from the cavity 101 into the second limiting fit structure 103. In this application, by having the first limiting structure 202 and the second limiting structure 203 extend into the first limiting fit structure 102 and the second limiting fit structure 103 respectively, the terminal 200 is effectively fixed in the cavity 101, preventing the housing 100 and the terminal 200 from loosening and relative displacement during use.

[0094] In order to achieve the cooperation between the second limiting structure 203 and the second limiting engagement structure 103 to prevent the terminal 200 from rotating relative to the housing 100 at least in the direction surrounding the longitudinal direction X, the two sides of the second limiting engagement structure 103 in the transverse direction Y fall into the rotation path of the second limiting structure 203 around the terminal body 201, so that when the terminal body 201 has rotation in the direction surrounding the longitudinal direction X, the second limiting structure 203 will abut against the two sides of the second limiting engagement structure 103 in the transverse direction Y to prevent the terminal 200 from rotating relative to the housing 100.

[0095] In some embodiments, a first limiting structure 202 is disposed on at least one side of the terminal body 201 in the transverse Y direction, and a second limiting structure 203 is disposed on at least one side of the terminal body 201 in the vertical Z direction, wherein the transverse Y direction and the vertical Z direction are perpendicular to each other, so that the housing 100 can provide the terminal 200 with a longitudinal X support force from two different directions. This arrangement allows the housing 100 to limit the terminal 200 from two different directions, preventing the terminal 200 and the housing 100 from moving or rotating relative to each other in the longitudinal X direction when subjected to external forces or vibrations, which is beneficial to improving the stability of the terminal assembly 10.

[0096] According to one embodiment of the present application, the terminal assembly 10 is provided with a first limiting structure 202 and a second limiting structure 203 spaced apart in the direction surrounding the longitudinal direction X. When the first limiting structure 202 and the second limiting structure 203 extend into the first limiting engagement structure 102 and the second limiting engagement structure 103 respectively, the housing 100 can provide the terminal 200 with a supporting force along the longitudinal direction X from two different directions. This arrangement allows the housing 100 to limit the terminal 200 from two different directions, preventing the terminal 200 and the housing 100 from moving or rotating relative to each other along the longitudinal direction X when subjected to external force or vibration, which is beneficial to improving the stability of the terminal assembly 10. Secondly, by limiting the engagement of the first limiting structure 202 with the first limiting engagement structure 102 and the second limiting structure 203 with the second limiting engagement structure 103, the limiting between the housing 100 and the terminal 200 is achieved, which can effectively reduce the loosening and displacement of the terminal 200 during use, thereby ensuring the stability of the electrical connection of the terminal assembly 10 and enabling the terminal assembly 10 to provide a reliable electrical connection in various usage environments.

[0097] It should be noted that the extending direction of the first limiting structure 202 is orthogonal to the extending direction of the second limiting structure 203, that is, the first limiting structure 202 and the second limiting structure 203 are spaced apart on the longitudinal direction X of the terminal body 201, so that the first limiting structure 202 and the second limiting structure 203 can be set at different positions on the longitudinal direction X. The extending direction of the first limiting structure 202 is perpendicular to the extending direction of the second limiting structure 203, that is, the first limiting structure 202 and the second limiting structure 203 can be set at the same position on the longitudinal direction X of the terminal body 201.

[0098] See in some examples Figure 1 The number of terminals 200 can be two, with the two terminals 200 spaced apart perpendicular to the horizontal Y direction. The two signal lines in the cable 70 can be connected to the mounting ports 201b of the two terminals 200 respectively. It should be noted that the above is merely illustrative and does not constitute a limitation of this application. Those skilled in the art will understand that the number of terminals 200 can also be three, four, or five, etc., and these examples should not be construed as limitations of this application.

[0099] In one embodiment provided in this application, the number of cavities 101 defined by the housing 100 corresponds one-to-one with the number of terminals 200. Each cavity 101 is provided with a first groove 102 and a second groove 103 corresponding to the first limiting structure 202 and the second limiting structure 203 on the corresponding terminal 200, respectively. For example, when there are two terminals 200, there are two cavities 101; when there are three terminals 200, there are three cavities 101. The multiple first limiting structures 102 are isolated from each other in the transverse Y direction, and the multiple second limiting structures 103 are isolated from each other in the transverse Y direction, so that no collision or interference occurs between adjacent terminals 200.

[0100] In some embodiments, see Figures 1 to 3 There are two first limiting structures 202, which are symmetrically arranged on opposite sides of the terminal body 201 in the longitudinal direction X. There are also two first limiting mating structures 102, which are symmetrically arranged on both sides of the housing 100 in the longitudinal direction X. The two first limiting mating structures 102 and the two first limiting structures 202 are correspondingly arranged so that the two first limiting structures 202 can be respectively engaged in the two first limiting mating structures 102, making the force on the terminal 200 in the circumferential direction more uniform and further improving the connection reliability between the terminal 200 and the housing 100.

[0101] Figure 8 This diagram shows a partial structural schematic of connector 1 according to the present application. Figure 9 Show Figure 8 A cross-sectional view of CC, in some embodiments, see [link to CC section]. Figures 1 to 9 The housing 100 also has a guide hole 104 for inserting a connector pin. The guide hole 104 communicates with the cavity 101, and the diameter of the guide hole 104 is smaller than the diameter of the connector 201a.

[0102] See in some examples Figure 3 The connector 201a is formed by two contact spring arms clamping together, creating a flared connector 201a. Specifically, the ends of the two contact spring arms furthest from the terminal body 201 extend radially outwards to form the flared connector 201a. It should be noted that the above is merely illustrative and does not constitute a limitation of this application. Those skilled in the art will understand that the connector 201a can also have other shapes, and these examples should not be construed as limiting this application.

[0103] In some embodiments, see Figure 1Both the housing 100 and the terminal 200 extend along the longitudinal direction X. The housing 100 has an insertion port 110 at one end of the longitudinal direction X. The terminal 200 is disposed inside the housing 100. The cable 70 passes through the insertion port 110 and connects to the terminal 200. This arrangement allows the cable 70 to pass directly through the insertion port 110 and connect to the terminal 200, reducing bending and loss of the cable 70 during the connection process and further improving the reliability of the electrical connection.

[0104] For example, the guide hole 104 and the insertion port 110 on the housing 100 are respectively provided at both ends of the terminal 200 in the longitudinal direction X. The insertion interface 201a on the terminal body 201 is exposed through the guide hole 104, so that the plug pin can be inserted into the insertion interface 201a of the terminal body 201 through the guide hole 104, thereby realizing the connection between the plug pin and the terminal body 201.

[0105] According to one embodiment of this application, the guide hole 104 serves to guide the insertion of the connector pin and reduces wear and damage to the connector 201a caused by inaccurate insertion of the connector pin and the connector 201a of the terminal body 201. Secondly, the diameter of the guide hole 104 is smaller than the diameter of the connector 201a so that even if the connector pin is misaligned, it can still be aligned and inserted into the connector 201a of the terminal body 201 via the guide hole 104 when the connector pin and connector 201a are mated. Furthermore, the embodiment of this application also allows the connection between the connector pin and the connector 201a of the terminal body 201 to be located within the cavity 101 of the housing 100, thereby protecting the connector 201a of the terminal body 201 and preventing damage caused by external forces.

[0106] In some embodiments, see Figures 1 to 3 The first limiting structure 202 includes barbs. In the direction from the insertion interface 201a to the mounting port 201b, the inclined surface of the barb extends away from the terminal body 201, that is, in the direction from the insertion interface 201a to the mounting port 201b, the barb gradually moves away from the terminal body 201 in the transverse Y direction.

[0107] For example, the terminal body 201 is hollow inside, and an opening 201d is provided on the side of the terminal body 201. One end of the first limiting structure 202 is connected to the side of the opening 201d adjacent to the insertion interface 201a, and the other end of the first limiting structure 202 extends toward the mounting opening 201b, thereby forming a barb with an inclined surface extending away from the terminal body 201. When the first limiting structure 202 is engaged in the first limiting mating structure 102, the end of the barb away from the terminal body 201 abuts against one side of the first limiting mating structure 102.

[0108] According to one embodiment of this application, by having the end of the barb away from the terminal body 201 abut against one side of the first limiting structure 102, the contact area between the first limiting structure 202 and the side of the first limiting structure 102 can be increased, thereby strengthening the limiting stability between the first limiting structure 202 and the first limiting structure 102.

[0109] Figure 6 This shows a schematic diagram of the structure of the housing 100 according to this application. Figure 7 Show Figure 6 A sectional view of BB, see in some examples. Figures 5 to 7 The cavity 101 includes a first channel 101a and a second channel 101b. In the direction from the insertion port 110 of the housing 100 toward the guide hole 104, the first channel 101a and the second channel 101b are adjacent and connected. The diameter of the first channel 101a is larger than the diameter of the second channel 101b, and the diameter of the first channel 101a is larger than the diameter of the terminal 200. The diameter of the second channel 101b is slightly larger than the diameter of the terminal body 201, and the diameter of the second channel 101b is smaller than the sum of the dimensions of the second limiting structure 203 and the terminal body 201 in the transverse Y direction. In the direction from the insertion port 110 of the housing 100 toward the guide hole 104, the second limiting engagement structure 103 and the first limiting engagement structure 102 are spaced apart on one side of the second channel 101b. When terminal 200 needs to be installed inside housing 100, the insertion interface 201a of terminal 200 is first inserted into the first channel 101a from the insertion port 110 of housing 100. When the first limiting structure 202 needs to enter the second channel 101b, the first limiting structure 202 abuts against the edge of the second channel 101b adjacent to the first channel 101a, so as to press the first limiting structure 202 radially inward into the opening 201d. When the first limiting structure 202 enters the first limiting mating structure 102 from the first channel 101a, the first limiting structure 202 uses its elastic restoring force to pop out radially outward, so that the end of the barb away from the terminal body 201 abuts against one side of the first limiting mating structure 102, and at the same time, the second limiting structure 203 abuts against the second limiting mating structure 103. This arrangement enables quick installation between terminal 200 and housing 100, and also enhances the connection stability between housing 100 and terminal 200.

[0110] In some embodiments, the terminal 200 may be made of a conductive material, such as metal, to give the terminal 200 a conductive effect. It should be noted that the above are merely illustrative examples and do not constitute a limitation of this application. Those skilled in the art will understand that the terminal 200 may also be other conductive materials, and these examples should not be construed as limiting this application.

[0111] In some examples, the first limiting structure 202 abuts against the side of the first limiting mating structure 102 adjacent to the second limiting mating structure 103, and the second limiting structure 203 abuts against the side of the second limiting mating structure 103 adjacent to the first limiting mating structure 102.

[0112] For example, the first limiting structure 202 and the second limiting structure 203 are spaced apart along the longitudinal direction X, and the first limiting mating structure 102 and the second limiting mating structure 103 are also spaced apart along the longitudinal direction X. The first limiting structure 202 abuts against one side of the first limiting mating structure 102, and the second limiting structure 203 abuts against one side of the second limiting mating structure 103 adjacent to the first limiting mating structure 102. That is, the first limiting structure 202 and the second limiting structure 203 abut against two adjacent sides of the first limiting mating structure 102 and the second limiting mating structure 103, respectively. With this arrangement, the terminal 200 cannot move back and forth relative to the housing 100 in the longitudinal direction X. For example, when the terminal body 201 is subjected to an external force from the guide hole 104 of the housing 100 toward the insertion port 110, the first limiting structure 202 abuts against the side of the first limiting mating structure 102 adjacent to the second limiting mating structure 103, thereby preventing relative movement between the first limiting structure 202 and the housing 100 in the longitudinal direction X. When the terminal body 201 is subjected to an external force from the insertion port 110 of the housing 100 toward the guide hole 104, the second limiting structure 203 abuts against the side of the second limiting mating structure 103 adjacent to the first limiting mating structure 102, thereby preventing relative movement between the first limiting structure 202 and the housing 100 in the longitudinal direction X.

[0113] In some examples, the terminal body 201 is defined with a notch that communicates with the internal hollow cavity of the terminal body 201, and the second limiting structure 203 is formed by extending radially outward from the edge of the notch.

[0114] For example, the two opposite edges of the notch extend radially outward to form two stop plates, and the ends of the two stop plates away from the notch abut each other, thereby enhancing the structural rigidity of the second limiting structure 203.

[0115] Figure 10 This shows a schematic diagram of the structure of the stop block 300 according to this application. Figure 11 This diagram illustrates the connection relationship between the stop block 300 and the housing 100 according to this application. In some embodiments, see [link to relevant documentation]. Figures 1 to 11The housing 100 defines a mounting groove 105, which communicates with the cavity 101. The second limiting structure 103 and the mounting groove 105 are adjacent to and communicate with each other along the longitudinal direction X. The terminal assembly 10 also includes a stop block 300, which can be inserted into the mounting groove 105. The second limiting structure 203 abuts against the stop block 300. The stop block 300 is used to prevent the terminal body 201 and the second limiting structure 203 from moving relative to the housing 100, at least in the longitudinal direction X.

[0116] For example, when the second limiting structure 203 is engaged with the second limiting mating structure 103, the stop block 300 can be inserted into the mounting groove 105 of the housing 100 by pressing, so that the stop block 300 can limit the second limiting structure 203 in the second limiting mating structure 103, thereby limiting the second limiting structure 203 and enhancing the connection stability between the terminal 200 and the housing 100.

[0117] It should be noted that the shape of the mounting groove 105 is adapted to the shape of the stop block 300 so that the stop block 300 can be securely inserted into the mounting groove 105.

[0118] In some embodiments, in the longitudinal direction X, the mounting groove 105 is located on the side of the second limiting engagement structure 103 away from the first limiting engagement structure 102. The second limiting structure 202 abuts against a portion of the surface of the stop block 300 adjacent to the first limiting engagement structure 102, preventing the terminal body 201 from moving relative to the housing 100 in the direction from the insertion interface 201a to the mounting port 201b. This arrangement enables restriction of the second limiting structure 202 in both directions of the longitudinal direction X.

[0119] In some embodiments, a slot 201c is defined on the terminal body 201, and a portion of the structure of the stop block 300 extends into the cavity 101 and is engaged within the slot 201c of the terminal body 201. In the longitudinal direction X, the stop block 300 and the terminal body 201 overlap to prevent relative movement between the first limiting structure 202 and the housing 100 in the longitudinal direction X.

[0120] For example, the slot 201c is recessed along the radial direction of the terminal body 201. When the second limiting structure 203 is engaged with the second limiting mating structure 103, the stop block 300 is inserted into the mounting groove 105 of the housing 100 by pressing. At this time, part of the structure of the stop block 300 extends into the slot 201c of the cavity 101, so that the stop block 300 can abut against the end faces of the mounting groove 105 on both sides of the longitudinal X direction, further preventing the first limiting structure 202 and the housing 100 from moving relative to each other in the longitudinal X direction.

[0121] In some embodiments, see Figures 1 to 11 The stop block 300 includes a positioning protrusion 301, and the housing 100 is defined with a positioning groove 106. The positioning groove 106 is adjacent to and connected to the mounting groove 105 along the longitudinal direction X. The positioning protrusion 301 is engaged in the positioning groove 106.

[0122] For example, to facilitate the installation of the stop block 300 into the mounting groove 105, the mounting groove 105 extends through the housing 100 in a transverse Y direction, so that the stop block 300 can be pressed into the mounting groove 105 by grasping both ends of the stop block 300. Based on this, the stop block 300 is prone to displacement within the mounting groove 105. Therefore, this application provides a positioning protrusion 301 on the stop block 300, and the positioning of the stop block 300 within the mounting groove 105 is achieved by engaging the positioning protrusion 301 into the mounting groove 105.

[0123] In some embodiments, see Figure 1 The housing 100 also includes a first observation hole 107 corresponding to the insertion interface 201a, through which the user can observe whether the connection between the insertion interface 201a and the pin is normal and whether the insertion interface 201a and the pin have been damaged during assembly. And / or, the housing 100 also includes a second observation hole 111 corresponding to the first limiting structure 202, through which the user can observe whether the first limiting structure 202 is securely engaged within the first limiting mating structure 102.

[0124] For example, the first observation hole 107 and the second observation hole 111 can be provided on one side of the housing 100, that is, the first observation hole 107 and the second observation hole 111 are provided on the side of the housing 100, and the first observation hole 107 and the second observation hole 111 are respectively connected to the cavity 101, so that the user can observe from the side of the terminal body 201 whether the connection between the plug interface 201a and the plug pin is normal and whether the first limiting structure 202 is firmly locked in the first limiting mating structure 102, so as to observe the working status of the terminal body 201 from a better angle.

[0125] In some examples, the number of first observation holes 107 and second observation holes 111 is adapted to the number of terminals 200. For example, when there are two first terminals 200, there are two first observation holes 107 and two observation holes 111. When there are three first terminals 200, there are three first observation holes 107 and three observation holes 111. It should be noted that the above are merely illustrative examples and do not constitute a limitation of this application. Those skilled in the art will understand that the number of terminals 200 can also be four, five, or six, etc., and it should be understood that these examples should not be construed as limitations of this application.

[0126] Figure 12This diagram illustrates the connection relationship between the first shield 20 and the housing 100 according to this application. Figure 13 An exploded view of the first shield 20 and housing 100 according to this application is shown. Figure 14 A schematic diagram of the structure of the first shield 20 according to this application is shown. See also Figures 12 to 14 This application also provides a connector 1, which includes a terminal assembly 10 as described in any of the above embodiments.

[0127] See Figures 12 to 14 This application embodiment also includes a first shielding cover 20, which is fitted over the outside of the housing 100. A first protrusion 30 is provided on the inner side of the first shielding cover 20, and a first groove 108 is defined on the housing 100. A portion of the first protrusion 30 is fitted into the first groove 108, thereby achieving a connection and fixation between the first shielding cover 20 and the housing 100. Furthermore, the first shielding cover 20 effectively prevents the cable 70 inside the terminal assembly 10 from being interfered with by complex external electromagnetic environments, and also prevents high-frequency signals inside the terminal assembly 10 from polluting the external electromagnetic environment.

[0128] In some embodiments, see Figures 12 to 14 The first shield 20 defines a second groove 210, and the first protrusion 30 extends from at least a portion of the edge of the second groove 210 into the first groove 108.

[0129] For example, the first protrusion 30 may be a protrusion extending from at least a portion of the edge of the second groove 210 toward the housing 100, and the first protrusion 30 and the first shield 20 may be integrally formed. When the first shield 20 is fitted onto the outside of the housing 100, a portion of the structure of the first protrusion 30 is engaged within the first groove 108, and the first protrusion 30 can prevent relative movement between the first shield 20 and the housing 100 along the longitudinal X direction by abutting against the two sides of the first groove 108 in the longitudinal X direction.

[0130] In some examples, there may be two first protrusions 30, which may be respectively disposed on the two sides of the transverse Y. Exemplarily, the two first protrusions 30 may include protrusions extending from the two sides of the second groove 210 toward the housing 100, and the two first protrusions 30 are integrally formed with the first shield 20.

[0131] In some embodiments, see Figures 12 to 14 The first protrusion 30 includes a first extension 310 and a first locking portion 320. One end of the first extension 310 is connected to at least a portion of the edge of the second groove 210, and the other end of the first extension 310 is connected to the first locking portion 320. The first locking portion 320 is locked in the first groove 108.

[0132] For example, when it is necessary to connect the first shield 20 and the housing 100, a plate can be pre-set on the side of the second groove 210, and then the first shield 20 is fitted onto the outside of the housing 100 until the first groove 108 and the second groove 210 correspond. Then, the first extension 310 is bent by riveting so that the first locking part 320 is locked in the first groove 108, thereby locking the first protrusion 30 into the first groove 108.

[0133] In some examples, the first extension 310, the first locking portion 320, and the first shielding cover 20 are integrally formed.

[0134] In some embodiments, see Figures 12 to 14 The first locking portion 320 abuts against at least a portion of the edge of the first groove 108. By overlapping the side of the first locking portion 320 with the first groove 108, the contact area between the first locking portion 320 and the first groove 108 is increased, thereby further enhancing the connection stability between the first shield 20 and the housing 100.

[0135] In some examples, there are two first protrusions 30, and the first locking portions 320 of the two first protrusions 30 respectively overlap the two sides of the first groove 108 in the transverse Y direction. This arrangement can restrict the movement of the first shield 20 and the housing 100 in the transverse Y direction.

[0136] In some embodiments, see Figures 12 to 14 The first shield 20 also includes a first limiting block 220. The outer wall surface of the housing 100 defines a snap-fit ​​surface 109, and the first limiting block 220 abuts against the snap-fit ​​surface 109. Exemplarily, the housing 100 includes a first portion adjacent to the cable 70 and a second portion away from the cable 70. The second portion has a smaller dimension in the vertical Z direction than the first portion in the vertical Z direction, so that the first portion and the second portion form an inclined snap-fit ​​surface 109. The first limiting block 220 is disposed at one end of the first shield 20 adjacent to the insertion interface 201a. The first limiting block 220 abuts against the snap-fit ​​surface 109 to limit the movement of the first shield 20 and the housing 100 in the longitudinal X direction.

[0137] In some examples, there may be two first limiting blocks 220, which are respectively disposed on opposite sides of the first shielding cover 20. There may also be two snap-fit ​​surfaces 109, which are respectively disposed on opposite sides of the housing 100. This is so that when the first shielding cover 20 is fitted onto the outside of the housing 100, the first shielding cover 20 can abut against the sides of the housing 100, thereby further restricting the relative movement of the first shielding cover 20 and the housing 100 and further improving the connection stability between the first shielding cover 20 and the housing 100.

[0138] Figure 15 This diagram illustrates the connection relationship between the first shielding cover 20 and the second shielding cover 40 according to this application. Figure 16 This diagram shows the structure of the second shielding cover 40 according to the present application. Figure 17 This diagram shows a structural schematic of connector 1 according to the present application. Figure 18 An exploded view of connector 1 according to this application is shown, see below. Figures 15 to 18 As a third aspect of this application, this application also provides a connector 1, which includes a terminal assembly 10, a first shielding cover 20 and a second shielding cover 40.

[0139] See Figures 1 to 3 The terminal assembly 10 includes a housing 100 and at least one terminal 200 disposed within the housing 100. The housing 100 has a first end and a cable end opposite each other along the longitudinal direction X. The first end and a guide hole 104 are disposed at one end of the housing 100 along the longitudinal direction X, and the cable end and an insertion port 110 are disposed at the other end of the housing 100 along the longitudinal direction X.

[0140] See Figures 12 to 14 , Figure 17 The first shield 20 is fitted outside the housing 100 and surrounds the cable end. The first shield 20 defines the second groove 210. The first shield 20 can effectively prevent the cable 70 in the terminal assembly 10 from being interfered with by the complex external electromagnetic environment, and can also prevent the high-frequency signal in the terminal assembly 10 from polluting the external electromagnetic environment.

[0141] See Figures 15 to 18 The second shielding cover 40 is fitted onto the outside of the housing 100 and surrounds the first end. The second shielding cover 40 has a second protrusion 50, which, through a partial structure, is engaged within the second groove 210, thereby achieving a limiting and fixing relationship between the first shielding cover 20 and the second shielding cover 40. The second shielding cover 40 effectively prevents the cable 70 inside the terminal assembly 10 from interference from complex external electromagnetic environments and also prevents high-frequency signals inside the terminal assembly 10 from polluting the external electromagnetic environment.

[0142] It should be noted that these technical features can be used individually or in combination. For example, the housing 100, the first shield 20, the second shield 40, and at least one terminal 200 can be assembled together to form a connecting assembly that can be inserted into the connector 1 housing. Features on the connecting assembly can engage with features on the connector 1 housing. The connecting assembly can be locked inside the connector 1 housing using a locking seat. When the connecting assembly is inserted into the desired position inside the connector 1 housing, the locking seat can be pressed into the connector 1 housing, preventing the connecting assembly from being pulled out. If the connecting assembly is only partially inserted into the connector 1 housing, the connecting assembly can prevent the locking seat from being inserted.

[0143] The following section describes the solution of this application in conjunction with the connection relationships between various technical features. These connection relationships can be used to make physical connections between components in an automobile.

[0144] In some embodiments, see Figure 17 The first shield 20 and the second shield 40 have overlapping areas with the terminal assembly 10 in the vertical Z direction, and the second groove 210 and the second protrusion 50 are located in the overlapping area.

[0145] Exemplarily, a first shielding cover 20 is disposed on the side of the housing 100 adjacent to the insertion port 110, and a second shielding cover 40 is disposed on the side of the housing 100 adjacent to the guide hole 104, with the second shielding cover 40 fitted over a portion of the structure of the first shielding cover 20 to form an overlapping area. In some examples, since the connection between the cable 70 and the terminal 200 is relatively fragile, a portion of the structure of the first shielding cover 20 extends out of the housing 100 to cover the cable 70, so that the connection between the terminal body 201 and the cable 70 is surrounded within the first shielding cover 20, thereby protecting the connection between the terminal body 201 and the cable 70.

[0146] In some examples, after the terminal body 201 and the cable 70 are connected, the connection point of the terminal body 201 and the cable 70 can be housed inside the cavity 101 of the housing 100, or the connection point of the terminal body 201 and the cable 70 can be located outside the cavity 101 of the housing 100.

[0147] In some embodiments, see Figures 12 to 14 The first shielding cover 20 is provided with a first protrusion 30, and the housing 100 is defined by a first groove 108. Part of the structure of the first protrusion 30 is fitted into the first groove 108, thereby achieving a connection and fixation between the first shielding cover 20 and the housing 100. Secondly, the first shielding cover 20 can effectively prevent the cable 70 inside the terminal assembly 10 from being interfered with by the complex external electromagnetic environment, and can also prevent the high-frequency signals inside the terminal assembly 10 from polluting the external electromagnetic environment.

[0148] In some embodiments, the first protrusion 30 and the second protrusion 50 are disposed at a longitudinal X-distance within the second groove 210.

[0149] For example, the first protrusion 30 may be a protrusion extending from at least a portion of the edge of the second groove 210 toward the housing 100. When the first shield 20 is fitted onto the outside of the housing 100, a portion of the structure of the first protrusion 30 is engaged within the first groove 108, thereby restricting relative movement between the housing 100 and the first protrusion 30. In this embodiment, the space of the second groove 210 is utilized to engage a portion of the structure of the second protrusion 50 within the second groove 210, thereby restricting relative movement between the first protrusion 30 and the second protrusion 50.

[0150] In the embodiments of this application, see Figures 14 to 15 In the process of forming the second groove 210, it is only necessary to design the second groove 210 to be larger in the longitudinal X direction so that the first groove 108 can simultaneously accommodate the first protrusion 30 and the second protrusion 50. This allows a portion of the structure of the second protrusion 50 to be engaged into the second groove 210 when the second shield 40 is fitted onto the outside of the first shield 20, thereby limiting the relative movement between the first protrusion 30 and the second protrusion 50. With this configuration, on the one hand, the connector of this application does not need to have an additional groove or engaging structure to engage with the second protrusion 50, making full use of the space of the second groove 210 of the first protrusion 30, directly engaging the second protrusion into the second groove, simplifying the manufacturing process of the first shield 20 and the second shield 40, and reducing the production cost of the first shield 20 and the second shield 40. On the other hand, it can strengthen the fixing effect between the first shield 20 and the second shield 40, and also ensure the limiting ability of the first shield 20 and the second shield 40 in multiple directions, preventing the first shield 20 and the second shield 40 from displacement during use.

[0151] In some embodiments, the first protrusion 30 extends into the first groove 108 from at least a portion of the edge of the second groove 210.

[0152] In some embodiments, see Figure 16 The second protrusion 50 includes a second extension 510 and a second locking portion 520. The second shield 40 defines a third groove 410. One end of the second extension 510 is connected to at least a portion of the edge of the third groove 410, and the other end of the second extension 510 is connected to the second locking portion 520. The second extension 510 is locked in the second groove 210.

[0153] For example, when it is necessary to connect the second shield 40 and the first shield 20, a plate can be pre-set on the side of the third groove 410, and then the second shield 40 is fitted onto the outside of the first shield 20 until the third groove 410 and the second groove 210 correspond. Then, the second extension 510 is bent by riveting so that the second locking part 520 is locked in the second groove 210.

[0154] In some examples, the second extension 510, the second locking portion 520, and the second shielding cover 40 are integrally formed.

[0155] See in some examples Figure 16 The second protrusion 50 may include a protrusion extending from at least a portion of the edge of the third groove 410 toward the housing 100. The second protrusion 50 and the second shield 40 may be integrally formed. When the second shield 40 is fitted onto the outside of the first shield 20, a portion of the structure of the second protrusion 50 is engaged within the second groove 210, thereby preventing relative movement between the first shield 20 and the housing 100 along the longitudinal direction X.

[0156] In some embodiments, see Figure 15 The second locking portion 520 abuts against at least a portion of the edge of the second groove 210. By overlapping the side of the second locking portion 520 with the second groove 210, the contact area between the second locking portion 520 and the second groove 210 is increased, thereby further enhancing the connection stability between the second shield 40 and the first shield 20.

[0157] In some embodiments, see Figure 15 The number of second protrusions 50 is at least two, and the at least two second protrusions 50 are respectively disposed on two opposite sides of the second groove 210.

[0158] For example, the two second protrusions 50 may be protrusions extending from the two sides of the third groove 410 toward the housing 100, and the two first protrusions 30 are integrally formed with the second shield 40.

[0159] In some embodiments, see Figure 15 A second limiting block 60 is provided on the first shielding cover 20, and the second limiting block 60 abuts against the edge of the second shielding cover 40, thereby realizing the positioning between the first shielding cover 20 and the second shielding cover 40.

[0160] For example, the second limiting block 60 protrudes vertically Z from the first shielding cover 20. When installing the second shielding cover 40, it is only necessary to ensure that the edge of the second shielding cover 40 adjacent to the cable 70 abuts against the second limiting block 60 to achieve the positioning of the first shielding cover 20 and the second shielding cover 40.

[0161] In some examples, the second limiting block 60 is integrally formed with the first shielding cover 20.

[0162] Figure 19 A schematic diagram of the cable 70 according to this application is shown. See also: Figure 19 In some embodiments, this application also includes a cable 70, which includes a conductive inner core 710 and an insulating sheath 720. The insulating sheath 720 covers the outer surface of the conductive inner core 710. The terminal 200 has a plug-in interface 201a and a mounting port 201b. At least a portion of the conductive inner core 710 extending from the insulating sheath 720 is inserted into the mounting port 201b.

[0163] In some examples, the insulating sleeve 720 may have two conductive inner cores 710, which can be used to connect the positive and negative terminals of the power supply, respectively. In this case, each conductive inner core 710 may have an insulating layer, and the insulating sleeve 720 wraps around the outside of the insulating layer, exposing part of the structure of the conductive inner core 710. The exposed part of the conductive inner core 710 is inserted into the mounting port 201b of the terminal 200.

[0164] In some examples, there are two terminals 200, which are spaced apart in the transverse Y direction. When the two conductive cores 710 can be connected to the two terminals 200 respectively, the spaced arrangement of the terminals 200 can ensure the insulation performance between the two conductive cores 710.
