Technical Field

[0001] The utility model relates to the technical field of connectors, and in particular discloses a narrow-body floating hybrid connector for an energy storage battery. Background Art

[0002] With the rapid development of new energy application technology, various intelligent transportation tools, intelligent manufacturing and intelligent equipment powered by new energy have been increasingly widely integrated into the daily production and life of the general public. These intelligent products have different functions, some simple and some complicated, and all require stable and reliable power support. Connectors are currently the most commonly used new energy power connection components, and their performance directly affects the stability of new energy products.

[0003] New energy vehicles are the most common multifunctional civilian intelligent transportation tools. Their use environment is complex and changeable. They need to ensure safety in use and the continuous effectiveness of various functions. Therefore, a large number of connectors are used in production to ensure power connectivity and transmission of functional signals. The applicant found that the new energy storage market has increasingly higher requirements for the performance of floating performance products that can use large currents and signals at the same time, while the product structure size is required to be smaller and smaller. Therefore, due to the limitations of the structure, the entire energy storage product space has less and less space left for external connections. Therefore, a narrow-body floating hybrid connector for energy storage batteries is urgently needed. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model aims to provide a narrow-body floating hybrid connector for an energy storage battery.

[0005] To achieve the above-mentioned purpose, the utility model provides a narrow-body floating hybrid connector for an energy storage battery, comprising a first connector, the first connector comprising a first shell and a first terminal group accommodated in the first shell; the first terminal group comprises a first terminal and a third terminal, the first terminal and the third terminal are arranged in a collinear manner, and the collinear direction of the first terminal and the third terminal is parallel to the length direction of the first shell.

[0006] Preferably, a plurality of first terminals and a plurality of third terminals are provided, and the plurality of third terminals are arranged in a matrix, and the plurality of first terminals are arranged in parallel and coplanar with each other. Since the first terminals are arranged in parallel and coplanar with each other, this layout can maximize the use of space, so that more connection points can be accommodated in a limited space, thereby improving the connection density. At the same time, this coplanar arrangement is conducive to ensuring that the connection between all first terminals and other components or systems is more consistent and reliable, thereby improving the connection efficiency. The parallel arrangement of the first terminals is conducive to optimizing the electrical connection path, reducing impedance and interference, and thus improving the electrical performance of the entire battery system. The third terminals arranged in a matrix also help to optimize the electrical layout, making the current or signal transmission more uniform and efficient.

[0007] Preferably, the narrow-body floating hybrid connector for the energy storage battery also includes a second connector that is plugged and matched with the first connector. The second connector includes a second shell used in conjunction with the first shell and a second terminal group accommodated in the second shell. The first terminal group is used in conjunction with the second terminal group to realize power and signal transmission. A second fool-proofing piece is provided on the second shell to be used in conjunction with the first fool-proofing piece. The first fool-proofing piece is used in conjunction with the second fool-proofing piece to realize fool-proof plugging of the first shell and the second shell. The mutual matching design of the first fool-proofing piece and the second fool-proofing piece ensures that the first shell of the first connector can only be plugged with the second shell of the second connector in the correct position and direction, effectively preventing connection errors caused by misplugging, and improving the accuracy and reliability of power and signal transmission. Due to the precise matching of the first fool-proofing piece and the second fool-proofing piece, the connector can form a stable connection structure after plugging, effectively resist external vibration and impact, and ensure the stability of power and signal transmission. Through the fool-proofing design, the damage and replacement of the connector caused by misplugging are reduced, thereby extending the service life of the connector and reducing maintenance costs.

[0008] Preferably, the shell includes a bearing part and a plug-in part, and the bearing part is cooperated with a limiting member and a reinforcing plate. The limiting member is used to limit the shell and the reinforcing plate on the external bearing part, and the reinforcing plate is attached to the bearing part. A fourth slot body for accommodating the plug-in part and a fifth slot body for accommodating the first anti-foolproofing member are provided on the reinforcing plate body. The fifth slot body is used to achieve anti-foolproofing during the installation of the plug-in part. The bearing part is fixed to the reinforcing plate body by the limiting member, which ensures the stable position of the connector shell on the reinforcing plate body and effectively prevents displacement or falling off caused by vibration or external force. The plug-in part is accommodated in the fourth slot body of the reinforcing plate body, which not only provides precise guidance and positioning for the plug-in part, but also protects the plug-in part to prevent it from being damaged by the external environment. The design of the fifth slot body is specially designed to accommodate the first anti-foolproofing member and the second anti-foolproofing member, so that during the installation of the connector, the anti-foolproofing member can be used to ensure the correct installation direction and position, thereby avoiding misoperation.

[0009] Preferably, two fifth slot bodies are provided, the fifth slot body is connected to the fourth slot body, two fifth slot bodies are provided, the line between the two fifth slot bodies and the central axis Aa in the length direction of the reinforcing plate body are spaced apart and arranged in parallel, the central axis Aa in the length direction of the reinforcing plate body coincides with the central axis Aa in the length direction of the fourth slot body, and the two fifth slot bodies serve as precise positioning points of the connector on the reinforcing plate body, ensuring that the first foolproof part and the second foolproof part can be accurately inserted into the corresponding slot body, and because the line between the two fifth slot bodies does not coincide with the symmetry axis Aa of the reinforcing plate body, the installation direction of the connector is restricted and can only be inserted into the reinforcing plate body at a specific angle and direction, this design effectively prevents reverse installation or tilted installation caused by human error, and enhances the foolproof effect, and the setting of the two fifth slot bodies makes the fixation of the connector on the reinforcing plate body more stable. This design helps to reduce the risk of loosening or falling off of the connector due to vibration or external force, and improves the structural stability of the entire energy storage system.

[0010] Preferably, a third anti-foolproofing part is provided on the side of the shell away from the first anti-foolproofing part. The third anti-foolproofing part is used to prevent the shell from being installed on the reinforcing plate body away from the side of the reinforcing plate body to achieve anti-foolproof installation of the shell. The third anti-foolproofing part is arranged at a specific position of the shell, and its shape, size or structure is designed to not match any possible contact surface on the reinforcing plate body, thereby preventing the shell from contacting or installing with the reinforcing plate body in the wrong direction. This design is intended to ensure that the shell can only be installed on the reinforcing plate body in the correct direction and position, which not only improves the accuracy and reliability of the installation process, but also reduces the maintenance and replacement costs caused by misoperation. At the same time, this design also improves the safety of the equipment and avoids safety risks that may be caused by installation errors. Therefore, the setting of the third anti-foolproofing part not only achieves the anti-foolproofing effect, but also improves the stability and reliability of the entire energy storage system.

[0011] Preferably, a first fixing member for limiting the terminal group is also detachably provided on the shell, and the first fixing member is used to limit the external wiring harness so that it is electrically connected to the terminal group. The first fixing member can firmly fix the position of the terminal group in the shell to prevent it from moving or misaligning during the use of the connector, thereby ensuring the stability of the internal structure of the connector and thus ensuring the stable transmission of power and signals. The first fixing member not only fixes the terminal group, but also limits the external wiring harness to maintain a stable electrical connection with the terminal group, avoiding the problem of poor electrical connection caused by loose or misaligned wiring harness, and ensuring the efficient and reliable operation of the connector in the energy storage system. Through the carefully designed first fixing member, the overall structure of the connector can be optimized while ensuring functionality, making it more compact, which not only improves the space utilization of the energy storage system, but also helps to improve the safety of the entire system and reduce safety hazards that may be caused by looseness or misalignment.

[0012] Preferably, the shell is further provided with a seventh groove body which passes through the bottom wall of the accommodating blind groove and is connected to the accommodating blind groove. The seventh groove body is used to guide the external sheet-like fixture to be inserted into the accommodating blind groove of the shell to squeeze the elastic sheet, so that the free end of the elastic sheet approaches the first fixing part to cancel the blocking limit by the protrusion so that the first fixing part can be withdrawn from the accommodating blind groove of the shell. This temporary release mechanism makes it possible to easily release the fixing force of the elastic sheet by inserting the sheet-like fixture when the external wiring harness needs to be disassembled or replaced, thereby facilitating maintenance or replacement operations.

[0013] Preferably, two first grooves for accommodating the limiting member are provided on the shell, the limiting member comprises a pressing cover, a column part arranged on the pressing cover, and a locking part arranged on the column part, the outer diameter of the pressing cover is larger than the outer diameter of the column part, and the locking part is used to be fixed on the reinforcing plate body or the bearing member; the groove diameter of the first groove body is larger than the outer diameter of the column part, and the column part is movably accommodated in the first groove body; the pressing cover is used to resist the bearing part of the pressing shell; the shell floats along the length direction of the reinforcing plate body via the first groove body, and since the shell can float between the two limiting members, it can better adapt to changes in the external environment. This design enables the connector to maintain good working performance under environmental conditions such as temperature changes and vibrations under the adjustment of the staff, thereby improving the environmental adaptability of the connector.

[0014] The beneficial effects of the utility model are as follows: through the co-linear design of the first terminal and the third terminal, and the direction is parallel to the length direction of the shell, this layout significantly reduces the space occupied by the connector in the width direction, thereby realizing a narrow body design, which is particularly important for the interior of the battery module or for scenarios requiring high-density installation, and helps to improve the system's integration and space utilization. The co-linearly arranged terminals make the connector more compact in the width direction, and the first shell provides solid protection and support for the internal terminals, ensuring the stability and reliability of the connector in complex environments. At the same time, the narrow body design does not sacrifice the overall strength and durability of the connector. Since the terminal layout is compact and orderly, this connector can be assembled with other components or systems more quickly and accurately, reducing the difficulty and cost of assembly, and the co-linearly designed terminals are conducive to optimizing the electrical connection path, reducing impedance and interference, thereby improving the electrical performance of the entire battery system.

[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0030] See also Figures 1 to 12 As shown, a narrow-body floating hybrid connector for an energy storage battery of the utility model comprises a first connector 1, wherein the first connector 1 comprises a first shell 11 and a first terminal group accommodated in the first shell 11; the first terminal group comprises a first terminal 17 and a third terminal 18, the first terminal 17 and the third terminal 18 are collinearly arranged, and the collinear direction of the first terminal 17 and the third terminal 18 is parallel to the length direction of the first shell 11.

[0031] Specifically, through the colinear design of the first terminal 17 and the third terminal 18, and the direction is parallel to the length direction of the shell, this layout significantly reduces the space occupied by the connector in the width direction, thereby realizing a narrow body design, which is particularly important for the interior of the battery module or in scenarios requiring high-density installation, and helps to improve the system's integration and space utilization. The colinearly arranged terminals make the connector more compact in the width direction. The first shell 11 provides solid protection and support for the internal terminals, ensuring the stability and reliability of the connector in complex environments. At the same time, the narrow body design does not sacrifice the overall strength and durability of the connector. Due to the compact and orderly terminal layout, this connector can be assembled with other components or systems more quickly and accurately, reducing the difficulty and cost of assembly, and the colinearly designed terminals are conducive to optimizing the electrical connection path, reducing impedance and interference, thereby improving the electrical performance of the entire battery system.

[0032] Specifically, a plurality of first terminals 17 and third terminals 18 are provided, and the plurality of third terminals 18 are arranged in a matrix. The plurality of first terminals 17 are arranged parallel to each other and in the same plane. Since the first terminals 17 are arranged parallel to each other and in the same plane, this layout can maximize the use of space, so that more connection points can be accommodated in a limited space, thereby improving the connection density. At the same time, this coplanar arrangement is conducive to ensuring that the connection between all first terminals and other components or systems is more consistent and reliable, thereby improving the connection efficiency. The parallel arrangement of the first terminals 17 is conducive to optimizing the electrical connection path, reducing impedance and interference, and thus improving the electrical performance of the entire battery system. The third terminals 18 arranged in a matrix also help to optimize the electrical layout, making the current or signal transmission more uniform and efficient.

[0033] Specifically, the first housing 11 is provided with a first foolproof component 12 and a third foolproof component 14 , and the first foolproof component 12 and the third foolproof component 14 are respectively located on the front and back sides of the first housing 11 .

[0034] Specifically, the narrow-body floating hybrid connector for energy storage batteries also includes a second connector 2 that is plugged and matched with the first connector 1. The second connector 2 includes a second shell 21 used in conjunction with the first shell 11, and a second terminal group accommodated in the second shell 21. The first terminal group is used in conjunction with the second terminal group to achieve power supply and signal transmission; the second shell 21 is provided with a second foolproof member 22 used in conjunction with the first foolproof member 12. The first foolproof member 12 is used in conjunction with the second foolproof member 22 to achieve foolproof plugging of the first shell 11 and the second shell 21. The first foolproof member 12 and the second foolproof member 22 are mutually connected. The mutual matching design ensures that the first shell 11 of the first connector 1 can only be plugged into the second shell 21 of the second connector 2 in the correct position and direction, effectively preventing connection errors caused by misplugging and improving the accuracy and reliability of power and signal transmission. Due to the precise matching of the first anti-foolproofing part 12 and the second anti-foolproofing part 22, the connectors can form a stable connection structure after plugging, effectively resisting external vibration and impact, and ensuring the stability of power and signal transmission. Through the anti-foolproofing design, connector damage and replacement caused by misplugging are reduced, thereby extending the service life of the connector and reducing maintenance costs.

[0035] Specifically, the first foolproof component 12 is plug-connected with the second foolproof component 22 .

[0036] Specifically, the housing includes a bearing portion 111 and a plug-in portion 112. The bearing portion 111 is provided with a limiting member 15 and a reinforcing plate 3. The limiting member 15 is used to limit the housing and the reinforcing plate 3 on the external bearing member. The reinforcing plate 3 is attached to the bearing portion 111. The reinforcing plate 3 is provided with a fourth slot 32 for accommodating the plug-in portion 112 and a fifth slot 33 for accommodating the first foolproof member 12. The fifth slot 33 is used to realize foolproofing during the installation of the plug-in portion 112. The bearing portion 111 is fixed to the reinforcing plate 3 by the limiting member 15 to ensure The connector housing is stably positioned on the reinforcing plate 3, effectively preventing displacement or falling off due to vibration or external force. The plug-in portion 112 is accommodated in the fourth slot 32 of the reinforcing plate 3, which not only provides precise guidance and positioning for the plug-in portion 112, but also protects the plug-in portion 112 from damage by the external environment. The fifth slot 33 is designed to accommodate the first anti-foolproofing member 12 and the second anti-foolproofing member 22, so that during the installation of the connector, the anti-foolproofing member can be used to ensure the correct installation direction and position, thereby avoiding misoperation.

[0037] Specifically, one or more reinforcing plates 3 are provided. In the present embodiment, two reinforcing plates 3 are provided. The two reinforcing plates 3 are respectively used to be installed on the front and back sides of the connector, i.e., for internal and external anti-mistake installation. However, in actual use, only one of the reinforcing plates 3 is used. For example, the first anti-mistake component 12 and the third anti-mistake component 14 are respectively located on the front and back sides of the first shell 11, so that both the internal and external installations of the connector can achieve anti-mistake installation.

[0038] Specifically, in the present embodiment, the first anti-foolproofing component 12 and the third anti-foolproofing component 14 respectively realize internal and external anti-foolproofing. The so-called internal anti-foolproofing is to prevent reverse installation when two connectors are plugged in and connected. The third anti-foolproofing component 14 is used to prevent the connector from being incorrectly installed relative to the reinforcing plate 3 when the connector is installed on the reinforcing plate 3 / to be plugged into an external carrier on which the connector is installed. The third anti-foolproofing component 14 plays an anti-foolproofing role by contacting the reinforcing plate 3.

[0039] Specifically, in this embodiment, the bearing portion 111 and the limiting member 15 are separately provided.

[0040] Specifically, in this embodiment, the first anti-idiot component 12 and the second anti-idiot component 22 are not in the same shape, two reinforcing plates 3 are provided, and the fifth grooves 33 on the two reinforcing plates 3 are used in conjunction with the first anti-idiot component 12 and the second anti-idiot component 22 respectively.

[0041] Specifically, there are two fifth slot bodies 33, which are connected to the fourth slot body 32, and there are two fifth slot bodies 33. The line between the two fifth slot bodies 33 and the central axis Aa in the length direction of the reinforcing plate body 3 are spaced apart and arranged in parallel. The central axis Aa in the length direction of the reinforcing plate body 3 coincides with the central axis in the length direction of the fourth slot body 32. The two fifth slot bodies 33 serve as precise positioning points of the connector on the reinforcing plate body 3, ensuring that the first foolproof part 12 and the second foolproof part 22 can be accurately inserted into the corresponding slot body. Since the line between the two fifth slot bodies 33 does not coincide with the symmetry axis Aa of the reinforcing plate body 3, the installation direction of the connector is limited and can only be inserted into the reinforcing plate body 3 at a specific angle and direction. This design effectively prevents reverse installation or tilted installation caused by human error, enhances the foolproof effect, and the setting of the two fifth slot bodies 33 makes the connector more firmly fixed on the reinforcing plate body 3. This design helps to reduce the risk of loosening or falling off of the connector due to vibration or external force, and improves the structural stability of the entire energy storage system.

[0042] Specifically, a third anti-foolproofing part 14 is provided on the side of the shell away from the first anti-foolproofing part 12. The third anti-foolproofing part 14 is used to prevent the shell from being installed on the side away from the reinforcing plate 3 to achieve anti-foolproof installation of the shell. The third anti-foolproofing part 14 is provided at a specific position of the shell, and its shape, size or structure is designed to not match any possible contact surface on the reinforcing plate 3, thereby preventing the shell from contacting or being installed with the reinforcing plate 3 in the wrong direction. This design is intended to ensure that the shell can only be installed on the reinforcing plate 3 in the correct direction and position, which not only improves the accuracy and reliability of the installation process, but also reduces the maintenance and replacement costs caused by misoperation. At the same time, this design also improves the safety of the equipment and avoids safety risks that may be caused by installation errors. Therefore, the setting of the third anti-foolproofing part 14 not only achieves the anti-foolproofing effect, but also improves the stability and reliability of the entire energy storage system.

[0043] Specifically, a first fixing member 4 for limiting the terminal group can be detachably provided on the shell. The first fixing member 4 is used to limit the external wiring harness so that it is electrically connected to the terminal group. The first fixing member 4 can firmly fix the position of the terminal group in the shell to prevent it from moving or misaligning during the use of the connector, thereby ensuring the stability of the internal structure of the connector, thereby ensuring the stable transmission of power and signals. The first fixing member 4 not only fixes the terminal group, but also limits the external wiring harness to maintain a stable electrical connection with the terminal group, avoiding the problem of poor electrical connection caused by loose or misaligned wiring harness, and ensuring the efficient and reliable operation of the connector in the energy storage system. Through the carefully designed first fixing member 4, the overall structure of the connector can be optimized while ensuring functionality to make it more compact, which not only improves the space utilization of the energy storage system, but also helps to improve the safety of the entire system and reduce safety hazards that may be caused by looseness or misalignment.

[0044] Specifically, the bearing portion 111 of the shell has a blind groove and an anti-foolproof protrusion 43 protruding into the blind groove. The blind groove is used to accommodate the first fixing member 4. The length direction of the anti-foolproof protrusion 43 is perpendicular to the length direction of the shell. The first fixing member 4 is provided with a sixth groove body 41 for accommodating the anti-foolproof protrusion 43. The anti-foolproof protrusion 43 is used in conjunction with the sixth groove body 41 on the first fixing member 4 to form a special locking mechanism. When the anti-foolproof protrusion 43 is fully embedded in the sixth groove body 41, it can limit the movement of the first fixing member 4 on the shell. This locking mechanism significantly enhances the fixing effect of the first fixing member 4 and prevents it from loosening or shifting due to vibration or external force during operation, thereby ensuring the stability and reliability of the internal structure of the connector. Due to the matching relationship between the anti-foolproof protrusion 43 and the sixth slot body 41, the first fixing member 4 can only cooperate with the shell in a specific direction and position to form an anti-foolproof structure during the installation process. This design improves the accuracy of installation and avoids installation errors caused by misoperation. At the same time, since the matching between the anti-foolproof protrusion 43 and the sixth slot body 41 is relatively simple and direct, the convenience of installation is also improved and the difficulty of operation is reduced. Through the cavity 6, the anti-foolproof protrusion 43 and the sixth slot body 41, the overall structure of the connector can be optimized while ensuring functionality. The optimized structure makes the connector more compact, which not only improves the space utilization of the energy storage system, but also helps to improve the performance and stability of the entire system, and can meet the requirements of external decoration while being compatible with internal decoration.

[0045] Specifically, an inclined elastic sheet 42 is provided on the first fixing member 4, and one end of the elastic sheet 42 close to the terminal group is connected to the first fixing member 4, and the elastic sheet 42 and the first fixing member 4 form an acute angle, and a ridge 44 protruding into the accommodating blind groove is provided on the shell, and the ridge 44 is used to stop the end of the free end of the limiting elastic sheet 42 to prevent the first fixing member 4 from withdrawing from the accommodating blind groove of the shell after being inserted into the shell, and the end of the elastic sheet 42 close to the terminal group is connected to the first fixing member 4 and forms an acute angle with the first fixing member 4. When the external wiring harness is connected to the terminal group, the free end of the elastic sheet 42 will be subjected to pressure and deformed, providing an adaptive fixing force, and this adaptive fixing force can Ensure the tight connection between the external wiring harness and the terminal group, and maintain a stable electrical connection even under vibration or external force. Due to the adaptive fixing force of the elastic sheet 42 and the limiting effect of the ridge 44, the connection process between the external wiring harness and the terminal group is simpler and more direct. During the installation process, the operator can complete the connection work without using additional tools or complicated steps, which improves work efficiency. At the same time, through the carefully designed elastic sheet 42 and ridge 44, the overall structure of the connector can be optimized while ensuring functionality. The optimized structure makes the connector more compact, which not only improves the space utilization of the energy storage system, but also helps to improve the performance and stability of the entire system.

[0046] Specifically, the power terminal of the first terminal group has a plug hole 118, which is recessed from the end surface of one end of the power terminal of the first terminal group. The power terminal of the second terminal group (i.e., the second terminal 25) has a contact head 115 inserted into the plug hole 118, and the contact head 115 is inserted into the plug hole 118 to achieve mutual conduction between the power terminals of the two terminal groups. The contact head 115 has a blind hole 116, which is recessed from the end surface of the free end of the contact head 115. An insulating anti-contact cap 117 covering the end surface of the free end of the contact head 115 is inserted into the blind hole 116. The insulating anti-contact cap 117 has an exhaust hole 119 penetrating the insulating anti-contact cap 117, and the exhaust hole 119 is connected to the blind hole 116.

[0047] Specifically, the signal terminal of the first terminal group has a receiving hole 27, one end of the signal terminal of the second terminal group has a plug contact 28 that is inserted into the receiving hole 27, and the other end of the signal terminal of the second terminal group has a clamping groove 29 and a clamping conductor for accommodating the conductor. The signal terminal of the second terminal group is formed by winding a sheet-like conductive sheet, and a process positioning hole 210 is provided at one end of the plug contact 28 away from the clamping groove 29. The process positioning hole 210 is used to accommodate an external positioning piece to facilitate the winding of the sheet-like conductive sheet and to position the opening direction of the clamping groove 29. That is, in the actual process of forming the signal terminal of the second terminal group, the external positioning member presses the sheet-like conductive sheet after blanking, and then starts to wind the sheet-like conductive sheet until the signal terminal of the second terminal group is formed. At this time, the opening direction of the clamping groove 29 of the signal terminal of the second terminal group after winding is the predetermined direction. For example, the opening direction of the clamping groove 29 of the signal terminal of the second terminal group after winding is upward, which is convenient for external conductors (such as wires) to be placed in the clamping groove 29 for clamping, assembly and connection.

[0048] Specifically, the shell is further provided with a seventh groove body 113 which passes through the bottom wall of the accommodating blind groove and is connected to the accommodating blind groove. The seventh groove body 113 is used to guide the external sheet-like fixture to be inserted into the accommodating blind groove of the shell to squeeze the elastic sheet 42, so that the free end of the elastic sheet 42 approaches the first fixing member 4 to cancel the blocking limit by the protrusion 44 so that the first fixing member 4 can be withdrawn from the accommodating blind groove of the shell. This temporary release mechanism makes it possible to easily release the fixing force of the elastic sheet 42 by inserting a sheet-like fixture when the external wiring harness needs to be disassembled or replaced, thereby facilitating maintenance or replacement operations.

[0049] Specifically, when the free end of the elastic sheet 42 approaches the first fixing member 4 and is no longer limited by the protruding ridge 44, the wiring harness fixed on the first fixing member 4 can be pulled back to realize assembly and disassembly of the wiring harness, thereby preventing the wiring harness from being inserted incorrectly.

[0050] Specifically, in this embodiment, the width dimension of the seventh groove body 113 is equal to the thickness dimension of the ridge 44, and the external sheet-shaped fixture can be a plastic part or a metal part.

[0051] Specifically, the connector also includes a limit member 15, and the shell is floated on the external reinforcement plate 3 via the limit member 15. The design of the limit member 15 allows the shell to be floated on the external reinforcement plate 3, which means that the position of the shell on the reinforcement plate is not completely fixed, but can be moved slightly within a certain range. The floating installation can alleviate the stress concentration and deformation caused by the manufacturing tolerance of the reinforcement plate or the shell, installation errors or external environmental changes such as temperature, vibration, etc., thereby protecting the integrity of the internal structure of the connector and extending the service life of the connector.

[0052] Specifically, two first grooves 13 for accommodating the limit members 15 are provided on the shell, and the limit members 15 include a pressing cover, a column portion arranged on the pressing cover, and a locking portion arranged on the column portion. The outer diameter of the pressing cover is larger than the outer diameter of the column portion, and the locking portion is used to be fixed on the reinforcing plate 3 or the bearing member; the groove diameter of the first groove 13 is larger than the outer diameter of the column portion, and the column portion is movably accommodated in the first groove 13; the pressing cover is used to resist the bearing portion 111 of the pressing shell; the shell floats along the length direction of the reinforcing plate 3 via the first groove 13. Since the shell can float between the two limit members, it can better adapt to changes in the external environment. This design enables the connector to maintain good working performance under environmental conditions such as temperature changes and vibrations under the adjustment of the staff, thereby improving the environmental adaptability of the connector.

[0053] Specifically, in this embodiment, the first housing 11 and the second housing 21 are respectively used in conjunction with a first fixing member 4 and a second fixing member 5 , and the first fixing member 4 and the second fixing member 5 have the same structure.

[0054] Specifically, the terminal group includes a first terminal 17 and a third terminal 18 accommodated in the first shell 11, and a first clip spring 19 and a second clip spring 110 used in conjunction with the first terminal 17 and the third terminal 18, or the terminal group includes a second terminal 25 and a fourth terminal 26 accommodated in the second shell 21, and a first clip spring 19 and a second clip spring 110 used in conjunction with the second terminal 25 and the fourth terminal 26. The first terminal 17 and the third terminal 18 serve as a female power terminal and a female signal terminal, respectively, and the second terminal 25 and the fourth terminal 26 serve as a male power terminal and a male signal terminal, respectively.

[0055] Specifically, in the present embodiment, three first terminals 17 are provided, and the three first terminals 17 are equidistant from each other and arranged on the same plane. The three first terminals 17 are respectively used to connect to the external positive pole, negative pole and ground wire, and the negative pole is connected to the ground wire. There are three first terminals 17, and the three terminals are equidistant from each other and arranged on the same plane, which not only ensures the electrical isolation between the terminals, but also simplifies the internal structure of the connector, making the overall design more compact and efficient.

[0056] Specifically, a process positioning hole for enclosing a circle is also provided on the fourth terminal 26. The process positioning hole is used to limit the external jig and then perform structural design on the fourth terminal 26.

[0057] Specifically, an insulating anti-touch cap 117 is also provided on the second terminal 25. The insulating anti-touch cap 117 is a cap body made of insulating material. In this embodiment, the insulating anti-touch cap 117 is made of plastic. The insulating anti-touch cap 117 can effectively protect the second terminal 25 and prevent direct contact between the human body and the second terminal 25.

[0058] Specifically, the power terminal of the first terminal group has a plug hole 118, and the power terminal of the second terminal group has a contact head 115 inserted into the plug hole 118. The contact head 115 has a blind hole 116, and the blind hole 116 is recessed from the end face of the free end of the contact head 115. An insulating anti-contact cap 117 covering the end face of the free end of the contact head 115 is inserted into the blind hole 116. The insulating anti-contact cap 117 has an exhaust hole 119 that penetrates the insulating anti-contact cap 117, and the exhaust hole 119 is connected to the blind hole 116.

[0059] Specifically, the insulating anti-touch cap 117 has a cap head and a guide member arranged on the cap head. The guide member is approximately truncated cone-shaped. The outer diameter of the guide member close to the cap head is equal to the outer diameter of the cap head, and the outer diameter of the guide member away from the cap head is smaller than the outer diameter of the cap head.

[0060] Specifically, an exhaust hole 119 is provided on the insulating anti-touch cap 117, and the exhaust hole 119 runs through the thickness direction of the cap head. The exhaust hole 119 is used to realize stealing, exhausting and positioning when the insulating anti-touch cap 117 is integrally injection-molded, and can effectively prevent it from deforming during subsequent use. During the injection molding process, the exhaust hole 119 serves as a channel for the flow of plastic melt, which helps to reduce the injection pressure, so that the plastic can fill the mold cavity more evenly, while reducing material waste and achieving the "stealing material" effect. With the injection of the plastic melt, the air and volatile gases in the mold cavity are quickly discharged through the exhaust hole, preventing the formation of bubbles and improving the yield and quality of the product. The exhaust hole 119 can also be used as a positioning element in the mold design to help the mold to be accurately positioned when the mold is closed, ensuring the shape and size accuracy of the insulating anti-touch cap 117. During subsequent use, the insulating anti-touch cap 117 may be affected by environmental factors such as temperature and humidity and deformed. The design of the exhaust hole increases the structural strength of the cap head to a certain extent, helps to reduce the occurrence of deformation, and maintains the stability and reliability of the insulating anti-contact cap 117.

[0061] Specifically, the signal terminal of the second terminal group has a accommodating hole 27, one end of the signal terminal of the first terminal group has a plug-in contact 28 that is inserted into the accommodating hole 27, and the other end of the signal terminal of the first terminal group has a clamping groove 29 for accommodating the conductor. The signal terminal of the first terminal group is formed by winding a sheet-like conductive sheet, and a process positioning hole 210 is provided at one end of the plug-in contact 28 away from the clamping groove 29. The process positioning hole 210 is used to accommodate an external positioning piece to facilitate the winding of the sheet-like conductive sheet and to position the opening direction of the clamping groove 29.

[0062] Specifically, the reinforcing plate 3 is further provided with a third slot 31 for accommodating the limiting member 15 . In this embodiment, the third slot 31 is a screw.

[0063] Specifically, a torsion spring 16 is further provided on the first terminal 17. The torsion spring has good vibration resistance and can maintain a stable electrical connection even in the case of vibration or shock, thereby avoiding loosening or disconnection of the connection due to vibration.

[0064] Specifically, a cut corner 114 is provided at the end of the first foolproof member 12 .

[0065] Specifically, the second anti-idiot piece 22 is provided with a protruding rib 23 used in conjunction with the first anti-idiot piece 12, and the second anti-idiot piece 22 is also provided with a second groove 24, which is used in conjunction with the cut corner 114 to facilitate the plug-in of the first anti-idiot piece 12 and the second anti-idiot piece 22.

[0066] Specifically, the bearing portion 111 and the plug-in portion 112 are integrally injection molded, and the first terminal group and the second terminal group each include a plurality of signal terminals and a plurality of power terminals. The plurality of signal terminals are arranged in a matrix, and the plurality of power terminals are arranged parallel to each other and in the same plane. The integral injection molding technology enables the bearing portion 111 and the plug-in portion 112 to be tightly combined during the manufacturing process to form a whole. This design not only simplifies the production process, but also improves the overall strength and stability of the connector, effectively improves the structural strength and durability of the connector, enables it to withstand greater external forces and vibrations, simplifies the manufacturing process, reduces production costs, and reduces performance degradation and safety hazards caused by loose or separated components.
