[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] Example 1 Please refer to Figure 1-Figure 11As shown, an embodiment of the present invention provides a connector, the connector comprising: A male end connection module 100, the male end connection module 100 comprises a male end body 11 and a positioning member 12, the male end body 11 is provided with a mounting through hole 13 at both ends of the x-axis, the positioning member 12 is fixedly mounted in the mounting through hole 13; The female end connection module 200 includes a female end body 21 and a positioning sleeve 22; the female end body 21 is provided with a positioning hole 23 at both ends of the x-axis, and each positioning hole 23 is embedded with a positioning sleeve 22; The signal connection module 300 includes a first signal terminal 31 installed on the male end body 11 and a second signal terminal 32 installed on the female end body 21; The electrical connection module 400 includes a first electrical connection terminal 41 installed at both ends of the first signal terminal 31 and a second electrical connection terminal 42 installed at both ends of the second signal terminal 32; When the male-end connection module 100 and the female-end connection module 200 are installed, the positioning piece 12 is inserted into the positioning sleeve 22; a first electrical terminal 41 is placed between two second electrical terminals 42, and a second signal terminal 32 is placed between two second signal terminals 32; the thickness of the first electrical terminal 41 is greater than the thickness of the second electrical terminal, and the thickness of the first signal terminal 31 is greater than the thickness of the second signal terminal 32.

[0026] Specifically, multiple first signal terminals 31 are installed in the middle of the male end body 11, and multiple second signal terminals 32 are installed in the middle of the female end body 21; multiple first electrical terminals 41 are symmetrically installed at both ends of the first signal terminal 31, and multiple second electrical terminals 42 are symmetrically installed at both ends of the second signal terminal 32.

[0027] Increasing the thickness of the first electrical terminal 41 and the first signal terminal 31 in the x-axis direction and the length thereof in the y-axis direction, namely increasing the cross-sectional area of ​​the first electrical terminal 41 and the first signal terminal 31 , improves the transmission efficiency of the first electrical terminal 41 and the first signal terminal 31 .

[0028] Accordingly, when increasing the cross-sectional area of ​​the first electrical terminal 41 and the first signal terminal 31, it is necessary to ensure the transmission efficiency of the first electrical terminal 41 and the second electrical terminal 42, and the transmission efficiency of the first signal terminal 31 and the second signal terminal 32, and accordingly increase the length of the second electrical terminal 42 and the second signal terminal 32 in the y-axis direction, and at the same time, adopt a method in which the two side surfaces of a first electrical terminal 41 are respectively fitted and contacted with a second electrical terminal 42, thereby increasing the total contact area of ​​the first electrical terminal 41 and the second electrical terminal. Similarly, the two sides of a first signal terminal 31 are respectively fitted and contacted with a second signal terminal 32, thereby increasing the contact area between the first signal terminal 31 and the second signal terminal 32, and realizing efficient current and electrical signal transmission. Due to the increase in the contact area, the problem of unstable connection is avoided, and the attenuation and reflection of the signal during the transmission of the first signal terminal 31 and the second signal terminal 32 are effectively reduced, thereby ensuring the integrity of the signal.

[0029] A plurality of first signal terminals 31 are installed in the middle of the male end body 11. On the x-axis, a plurality of electrical terminals are symmetrically distributed on both sides of the first signal terminal 31, so as to realize a reasonable layout of the first electrical terminals 41 and the first signal terminals 31 on the male end body 11, increase the number of the first electrical terminals 41 and the first signal terminals 31 on the male end body 11, improve the transmission speed of the electrical signal, reduce the electromagnetic interference between adjacent signal paths, enhance the anti-interference ability of the connector, and the symmetrical layout reduces the influence of external electromagnetic interference on signal transmission and improves the stability of electrical signal transmission.

[0030] In order to ensure the space occupation of the connector and meet the demand for miniaturization of the connector in electrical equipment, when increasing the size of the signal connection module 300 and the electrical connection module 400, it is necessary to control the material space size of the male end body 11 and the female end body 21 accordingly. After changing the space size of the male end body 11 and the female end body 21, in order to ensure the connection stability strength of the connector during the transmission process, the position connection of the male end body 11 and the female end body 21 is achieved by setting the positioning member 12 and the positioning sleeve 22. The male end body 11 and the female end body 21 are made of insulating members, the positioning member 12 and the positioning sleeve 22 are made of metal materials, and the positioning sleeve 22 is set in the positioning hole 23 in the female end body 21, so as to avoid the positioning member 12 directly inserted into the positioning hole 23 to cause the positioning hole 23 to be damaged, thereby enhancing the quality of the connector and avoiding the damage of the positioning hole 23 to affect the connection stability of the female end body 21 and the male end body 11.

[0031] The positioning piece 12 is installed at both ends of the male end body 11x axis, and is used to cooperate with the positioning sleeve 22 embedded in the positioning hole 23 to achieve accurate positioning during installation and ensure that the direction and amplitude of the shaking of the male end body 11 and the female end body 21 during the transmission of the connector current and electrical signals are the same, thereby ensuring the accuracy of the electrical signal transmission.

[0032] The male end body 11 has mounting holes 13 at both ends, and the metal positioning piece 12 and the male end body 11 are connected by injection molding, and the positioning piece 12 is fixed in the mounting hole 13 of the male end body 11. The metal positioning sleeve 22 and the female end body 21 are connected by injection molding, and the positioning sleeve 22 is fixed in the positioning hole 23, so as to ensure the stable connection between the positioning piece 12 and the male end body 11, and the positioning sleeve 22 and the female end body 21. After the positioning piece 12 and the positioning sleeve 22 are plugged and fixed, the stable connection between the male end body 11 and the female end body 21 and the precise alignment of the male end connection module 100 and the female end connection module 200 are ensured, so as to enhance the stability of the connection and avoid the interruption of the current and electrical signal transmission caused by the loose connection.

[0033] In summary, in the embodiment of the present invention, the thickness of the first electrical terminal 41 is greater than the thickness of the second electrical terminal 42, and the first electrical terminal 41 is placed between the two second electrical terminals 42, thereby increasing the contact area between the electrical terminals, reducing the contact resistance during signal transmission, thereby reducing the electrical loss during transmission, and at the same time enhancing the electrical transmission speed of the first electrical terminal 41 and the second electrical terminal 42, and reducing the risk of poor contact. The thickness of the first signal terminal 31 is greater than the thickness of the second signal terminal 32, and the first signal terminal 31 is placed between the two second signal terminals 32, increasing the contact area between the signal terminals, improving the reliability and stability of signal transmission, effectively reducing the attenuation and reflection of the signal during the transmission of the first signal terminal 31 and the second signal terminal 32, and ensuring the integrity of the signal. A positioning member 12 is provided on the male end body 11, which is used to be plugged and fixedly connected with the positioning sleeve 22 fixedly mounted on the female end body 21, ensuring that the male end connection module 100 and the female end connection module 200 can be accurately aligned during installation, while enhancing the stability of the connection, and avoiding the interruption of current and electrical signal transmission caused by loose connection.

[0034] Furthermore, the thickness of the first electrical terminal 41 is twice the thickness of the second electrical terminal 42 , and the thickness of the first signal terminal 31 is twice the thickness of the second signal terminal 31 .

[0035] Furthermore, the thickness of the first electrical terminal 41 is greater than twice the thickness of the second electrical terminal 42 , and the thickness of the first signal terminal 31 is greater than twice the thickness of the second electrical terminal 42 .

[0036] The transmission speed is increased by increasing the thickness of the first electrical terminal 41 and the first signal terminal 31 , and the contact area is increased by increasing the number of the second electrical terminal 42 and the second signal terminal 32 that are in contact with the first electrical terminal 41 and the first signal terminal 31 , thereby increasing the transmission speed.

[0037] In one embodiment, if Figure 4-7 as well as Fig. 9 , Fig.11 As shown, the second electrical terminal 42 includes a first fixing portion 421, a first contact portion 422 and a first abutting portion 423, and the first contact portion 422 is connected to the first fixing portion 421 and the first abutting portion 423 at two ends in the z-axis direction at a preset angle; The female end body 21 is provided with a plurality of insertion spaces 211 , and two second electrical terminals 42 are installed in each of the insertion spaces 211 . The two first contact portions 422 are close to each other on the x-axis, and an insertion cavity 212 is formed between the two first contact portions 422 .

[0038] Specifically, a plurality of pins are provided at one end of the first fixing portion 421 away from the first abutting portion 423 , and the pins are used to connect with other structures in the electrical device.

[0039] A convex cross beam 215 is respectively provided on both sides of the insertion port for inserting the first electrical terminal 41 at the bottom of the plug-in space 211, and the end of the first abutting portion 423 away from the first contact portion 422 abuts against the convex cross beam 215 to prevent the second electrical terminal 42 from slipping out of the insertion port at the bottom of the plug-in space 211.

[0040] The angle ao formed by the connection between the first fixing portion 421 and the first abutting portion 423 and the first contact portion 422 is a preset angle, so that the side surface of the first contact end 422 used for fitting and contacting with the first electrical terminal 41 can be located on the plane formed by the z-axis and the y-axis. When the first electrical terminal 41 is installed, the side surface used for fitting with the first contact end 422 is also located on the plane formed by the z-axis and the y-axis, so that the surface of the first contact end 422 is parallel to the side surface of the first electrical terminal 41 used for fitting and electrical connection, ensuring that the fitting and contacting surface between the second electrical terminal 42 and the first electrical terminal 41 is maximized. The preset angle is greater than 90° and less than 180°, and the second connection terminal with the corresponding preset angle is selected according to the size of the insertion space 211 and the thickness of the first electrical terminal 41.

[0041] The first contact portion 422 has a large area and is closely fitted to the first electrical terminal 41 , thereby ensuring the transmission efficiency between the first electrical terminal 41 and the second electrical terminal 42 .

[0042] Preferably, the preset angle formed between the first fixing portion 421 and the first contact portion 422 and the preset angle formed between the first abutting portion 423 and the first contact portion 422 are different in size. A second electrical terminal 42 with an adaptive preset angle is selected according to size requirements.

[0043] Preferably, a slideway (not shown) is provided on the protruding cross beam 215, and the depth of the slideway in the y-axis direction is shallow in the middle and deep at both ends, so that the water splashed inside can flow along the slideway to the outside of the insertion port.

[0044] The first contact portions 422 of the two second electrical terminals 42 are installed close to each other, so that a plug-in cavity 212 for plugging in the first electrical terminal 41 is formed between the two contact portions. In the plug-in cavity 212, the two side edges of the first electrical terminal 41 are respectively in contact with a second electrical terminal 42, and the two first contact portions 422 are tightly fitted with the first electrical terminal 41, which not only realizes the stable transmission of current and electrical signals, but also the two first contact portions 422 exert an extrusion force on the first electrical terminal 41 on the x-axis, thereby preventing the first electrical terminal 41 from sliding or directly sliding out of the plug-in cavity 212.

[0045] Preferably, the structure of the second signal terminal 32 is the same as that of the second electrical terminal 42, and includes a second fixing portion 321, a second contact portion 322 and a second abutment portion 323. The installation method of the second signal terminal 32 and the female end body 21 is the same as the installation method of the second electrical terminal 42 and the female end body 21. The two second signal terminals 32 are installed close to each other in the insertion space 211 with their second contact portions 322 thereon, and an insertion cavity 212 is formed between the two second contact portions 322 for inserting the first signal terminal 31. The two sides of the first signal terminal 31 are respectively in contact with one of the second contact portions 322.

[0046] The size of the second signal terminal 32 is smaller than that of the second electrical terminal 42, so that two or more second signal terminals 32 can be plugged into one row in the y-axis direction, while one second electrical terminal 42 can be plugged into one row in the y-axis direction. That is, in the y-axis direction, the length of the second signal terminal 32 is smaller than that of the second electrical terminal 42.

[0047] Meanwhile, the length dimension of the insertion space 211 where the two second signal terminals 32 are installed in the y-axis direction is smaller than the length dimension of the insertion space 211 where the second electrical terminal 42 is installed in the y-axis direction.

[0048] In one embodiment, if Figure 5 and Figure 7 As shown, two groups of interlocking grooves 213 are provided in one of the insertion spaces 211, and the two interlocking grooves 213 of the same group are respectively disposed at two ends of the y-axis direction, and an isolation protrusion 214 is disposed between the two interlocking grooves 213 at the same end; A first embedding plate 4211 is respectively provided on both sides of the first fixing portion 421 away from the first abutting portion 423 in the y-axis direction. The two first embedding plates 4211 on the same second electrical terminal 42 are embedded in a group of the embedding grooves 213 for fixed installation.

[0049] Specifically, Fig. 9 As shown, a plurality of pins are provided on the first fixing portion 421 on the second electrical terminal 42 and at one end away from the first abutting portion 423, and the pins are used to connect to the electrical structure outside the connector. The first fixing portion 421 and the pin connection position extend in a direction away from the pins on the z-axis to form the first engaging plate 4211.

[0051] like Fig.10 As shown, a plurality of pins are provided on the second fixing portion 321 on the second signal terminal 32 and at one end away from the second abutting portion 323, and the pins are used to connect to the electrical structure outside the connector. The second fixing portion 321 and the pin connection position extend in a direction away from the pin on the z-axis to form the second engaging plate 3211.

[0053] In the plug-in space 211, the convex cross beam 215 is arranged on both sides of the plug-in interface of the plug-in space 211 for inserting the first electrical terminal 41 and the first signal terminal 31 in the x-axis direction, and the gas flow channels 216 recessed toward the side wall of the female end body 21 are respectively arranged at both ends of the plug-in interface in the y-axis direction. Between the two opposite gas flow channels 216 on the y-axis, the first electrical terminal 41 and the first contact portion 422 are in close contact, and the air circulation space is increased through the gas flow channels 216, so that the heat generated by the signal connection module 300 and the electrical connection module 400 can be dissipated to the outside in time with the air flow.

[0054] The interlocking groove 213 and the isolating protrusion 214 are arranged at both ends of the plug-in space 211 in the y-axis direction and away from the gas flow channel 216 in the z-axis. The interlocking groove 213 is formed by being recessed into the side wall of the female end body 21 in the y-axis, and the isolating protrusion 214 is arranged between the two interlocking grooves 213 on the same side, forming a side wall of the interlocking groove 213 while allowing the first fixing portion 421 or the second fixing portion 321 of the two second electrical terminals 42 or the two second signal terminals 32 installed in the same plug-in cavity to maintain a certain distance. The arrangement of the interlocking groove 213 and the isolating protrusion 214 serves to fix the connection between the two second electrical terminals 42 or the two second signal terminals 32 and the female end body 21 while avoiding direct contact between the two second electrical terminals 42 or the two second signal terminals 32, thereby ensuring the accuracy of electrical transmission or signal transmission.

[0058] like Fig.10As shown, the second fixing portion 321 is a metal plate, and the metal plate is connected to a plurality of second contact portions 322, and the plurality of second contact portions 322 are arranged at a certain distance in the y-axis direction, and the number of the second contact portions 322 includes at least two. One end of each second contact portion 322 away from the second fixing portion 321 is connected to a second abutting portion 323, and one end of the second abutting portion 323 away from the second contact portion 322 abuts against the convex cross beam 215, so as to achieve the fixing of the second signal terminal 32 The same second electrical terminal 42 is provided with multiple first contact portions 422, and the same second signal terminal 32 is provided with multiple second contact portions 322, which can provide multiple contact points with the first electrical terminal 41 and the first signal terminal 31, so that even if some contact points are contaminated or worn during the use of the connector, other contact points can still maintain good electrical connection; leaving a certain gap between adjacent first contact portions 422 and adjacent second contact portions 322 can facilitate air flow and help heat dissipation. At the same time, the multiple first contact portions 422 and the second contact portions 322 disperse stress and reduce loose connections caused by mechanical vibration or impact.

[0059] In one embodiment, if Figure 4 and Fig. 9 As shown, the first electrical terminal 41 includes a first fixing portion 411 and a first plug-in portion 412, the first fixing portion 411 is fixed in the male end body 11, the first plug-in portion 412 is located outside the male end body 11 and inserted into the plug-in space 211, and the two side surfaces of the first plug-in portion 412 are respectively in contact with the first contact portion 422.

[0060] Specifically, Figure 4 and Fig. 9 As shown, the first fixing portion 411 of the first electrical terminal 41 is fixed in the male end body 11, ensuring that the first electrical terminal 41 and the second electrical terminal 42 will not be displaced due to vibration or other external forces. The first plug-in portion 412 of the first electrical terminal 41 is located outside the male end body 11. When the male end connection module 100 and the female end connection module 200 are assembled, the first plug-in portion 412 of the first electrical terminal 41 is inserted into the plug-in space 211 in the female end body 21 where the second electrical terminal 42 is installed, to achieve the second electrical connection with the female end body 21. Specifically, the first plug-in portion 412 is inserted into the plug-in cavity 212 between the two first contact portions 422 in the plug-in space 211, and the two side edges of the first plug-in portion 412 are tightly fitted with a first contact portion 422 respectively, to ensure a good electrical connection.

[0061] By fitting the two side surfaces with the first contact portion 422, multiple contact points are provided, the contact area is increased, and the reliability and stability of the connection are improved; at the same time, the first plug-in portion 412 can be in close contact with the first contact portion 422 when inserted into the plug-in space 211, ensuring a good electrical connection.

[0062] Similarly, if Figure 4 and Fig.10 As shown, the structure of the first signal terminal 31 is the same as that of the first electrical terminal 41, and the length of the first signal terminal 31 in the y-axis direction is less than the length of the first electrical terminal 41. The first signal terminal 31 includes a second fixing portion 311 and a second plug-in portion 312, wherein the second fixing portion 311 is installed and fixed in the male body 11, the second plug-in portion 312 is located outside the male body 11 and inserted into the plug-in space 211 where the second signal terminal 32 is installed, and the two side surfaces of the second plug-in portion 312 are respectively in contact with the second contact portion 322 of a second signal terminal 32.

[0063] In one embodiment, as described in 8, the male end body 11 is provided with a plurality of male end plug-in slots 14 between the two mounting through holes 13, a first electrical terminal 41 is installed in a male end plug-in slot 14, and a clamping platform 15 is provided on both sides of the male end plug-in slot 14 in the y-axis direction; One end of the first fixing portion 411 away from the first plugging portion 412 is provided with a first engaging convex edge 4111 on both sides of the y-axis, and the first engaging convex edge 4111 is engaged and fixed with the engaging platform 15 .

[0064] Specifically, the first fixing portion 411 of the first electrical terminal 41 is installed in the male plug-in slot 14, and the second fixing portion 311 of the first signal terminal 31 is installed in the male plug-in slot 14. The length dimension of the male plug-in slot 14 in which the first electrical terminal 41 is installed in the y-axis direction is greater than the length dimension of the male plug-in slot 14 in which the first signal terminal 31 is installed. In addition, in the y-axis direction, one male plug-in slot 14 can be arranged in the same row of the male body 11 for installing one first electrical terminal 41; at least two male plug-in slots 14 can be arranged in the same row of the male body 11 for installing at least two first signal terminals 31, so that more second signal terminals 32 can be plugged in without increasing the volume of the male body 11, thereby increasing the path of signal transmission.

[0065] When the first electrical terminal 41 is installed in the male end insertion slot 14 , the first engaging protrusion 4111 abuts against the clamping platform 15 in the male end insertion slot 14 to locate the installation position of the first electrical terminal 41 and the male end insertion slot 14 .

[0066] Similarly, one end of the first signal terminal 31 away from the second plug-in portion 312 is provided with a second engaging convex edge 3111 on both sides of the y-axis, and the second engaging convex edge 3111 is engaged and fixed with the card platform 15. When the first signal terminal 31 is installed in the male end plug-in slot 14, the second engaging convex edge 3111 abuts against the card platform 15 in the male end plug-in slot 14, positioning the first signal terminal 31 and the installation position in the male end plug-in slot 14.

[0067] In one embodiment, if Figure 4 As shown, the positioning member 12 includes a plug-in end 121 and a fixed end 122; A plug end 121, the plug end 121 is used to insert the positioning sleeve 22; The fixed end 122 is fixedly mounted to the male end body 11 .

[0068] Specifically, during the injection molding process of the male end body 11, the two metal positioning members 12 are respectively placed at predetermined positions so that after the injection molding is completed, the fixed end 122 of the positioning member 12 and the male end body 11 are tightly fixed together, and the plug end 121 of the positioning member 12 is located outside the male end body 11. The fixed installation between the fixed end 122 and the male end body 11 can ensure that the positioning member 12 remains stable during the entire use process, and will not loosen or fall off due to external forces, thereby ensuring the overall strength of the positioning member 12, and at the same time ensuring that the position of the positioning member 12 in the male end body 11 is fixed, preventing the positioning member 12 from being displaced during use.

[0069] When the male connection module 100 and the female connection module 200 are assembled, the plug-in ends 121 of the two positioning members 12 are respectively aligned with a positioning hole 23 on the female body 21 and inserted to achieve the connection between the positioning member 12 and the positioning hole 23, ensuring the accurate alignment between the male body 11 and the female body 21. The positioning sleeve 22 is embedded in the positioning hole 23, and after the plug-in end 121 is inserted into the positioning hole 23, it is inserted into the positioning sleeve 22. The positioning member 12 and the female body 21 are separated by the positioning sleeve 22 to prevent the positioning member 12 from directly contacting the inner wall of the positioning hole 23 when impacted, causing the inner wall of the positioning hole 23 to break or crack, affecting the stable connection between the male connection module 100 and the female connection module 200. At the same time, In this embodiment, through the design of the plug end 121 and the fixed end 122, the positioning member 12 can be accurately positioned and stably fixed in the male end body 11, ensuring that the connector will not be displaced or loosened during use. This design can improve the reliability and stability of the connector and is suitable for occasions requiring high-precision positioning and stable connection.

[0070] In one embodiment, if Figure 4As shown, the fixed end 122 includes a fixed member 1221, a connecting member 1223, and an abutting member 1222, wherein the abutting member 1222 is connected to the plug end 121, and the connecting member 1223 is disposed between the abutting member 1222 and the fixed member 1221; The mounting through hole 13 is provided with an abutment groove 131 and a fixing groove 132; the abutment groove 131 is provided on the surface of the male end body 11 on a side close to the female end connection module 200, and the fixing groove 132 is provided inside the male end body 11; The abutting member 1222 is embedded in the abutting groove 131 for installation, and the fixing member 1221 is embedded in the fixing groove 132 for installation, wherein the fixing groove 132 is an annular structure.

[0071] Specifically, the diameter of the fixing member 1221 and the abutment member 1222 is larger than the diameter of the connecting member 1223. Preferably, the abutment member 1222 is larger than the plug end 121, and plays a supporting role for the plug end 121 during installation. The abutment member 1222 is directly and tightly fixed in the abutment groove 131 during the injection molding process, so that the positioning member 12 can be perpendicular to the surface of the male end body 11, and there will be no positional deviation or shaking when inserted into the positioning hole 23 and the positioning sleeve 22.

[0072] The two ends of the connecting member 1223 are respectively connected to the fixing member 1221 and the abutting member 1222. Preferably, the fixing end 122 further includes a fixing rod 1224, and the diameter of the fixing rod 1224 is the same as the diameter of the connecting member 1223. The fixing member 1221 is arranged in the male end body 11 and abuts against the annular fixing groove 132 to achieve a stable connection between the positioning member 12 and the male end body 11.

[0073] The fixing rod 1224 is placed in the mounting through hole 13 in the male end body 11 to further fix the connection between the positioning member 12 and the male end body 11 .

[0074] In one embodiment, if Figure 7 and Figure 8 As shown, a plurality of stress grooves 50 are respectively arranged around the mounting through hole 13 and on both sides of the positioning hole 23, and the opening direction of the stress groove 50 arranged on the male end body 11 is the side of the male end body 11 away from the female end connection module 200 on the z-axis; The opening direction of the stress groove 50 disposed on the female end body 21 is the side of the female end body 21 away from the male end connection module 100 on the z-axis.

[0075] By providing stress grooves 50 around the mounting through hole 13 and the positioning hole 23, the amount of material used can be reduced, thereby reducing the weight of the entire connector; at the same time, the stress grooves 50 improve the stress distribution around the mounting through hole 13 and the positioning hole 23, reduce stress concentration, and improve the mechanical strength and reliability of the connector. The stress grooves 50 can also disperse stress, improve the fatigue resistance of the material, and extend the service life of the connector.

[0076] In one embodiment, if Figure 8 As shown, a stress groove 50 is provided between two adjacent male end plug-in grooves 14 , and the opening direction of the stress groove 50 is the side of the male end body 11 away from the female end connection module 200 on the z-axis.

[0077] Specifically, in order to increase the electrical transmission speed of the first electrical terminal 41, its thickness and length are increased, so that the cross-sectional area of ​​the first electrical terminal 41 is increased. In order to improve the integrity of the signal transmission of the first signal terminal 31, the thickness and number of the first signal terminal 31 are increased, resulting in an increase in the heat generated by the first electrical terminal 41 and the first signal terminal 31. By providing a stress groove 50 between two adjacent male end plug-in grooves 14, the generated heat can be quickly dissipated into the outside air, effectively reducing the thermal stress caused by temperature changes, thereby improving the thermal stability of the connector.

[0078] At the same time, by arranging a stress groove 50 between two adjacent male end plug-in grooves 14, the stress of the male end body 11 between the plug-in grooves can be effectively dispersed, thereby avoiding material fatigue or cracks caused by stress concentration, reducing the amount of material used, and thus reducing the weight of the connector; by dispersing stress, the stress groove 50 can improve the vibration resistance of the connector in a vibration environment and reduce loosening or damage of the connection caused by vibration.

[0079] Example 2 Based on the connector provided in the above embodiment 1, this embodiment provides an electrical device, the electrical device includes any one of the connectors described in the above embodiment 1, and the electrical device includes portable electronic devices, industrial automation equipment, medical equipment, automotive electronic systems and servers, and current and electrical signal centers, etc., to ensure that stable electrical connection and signal transmission can be maintained under various complex working conditions. The electrical device sets the thickness of the first electrical terminal 41 to be greater than the thickness of the second electrical terminal 42 through the connector, and the first electrical terminal 41 is placed between the two second electrical terminals 42, which increases the contact area between the electrical terminals and reduces the contact resistance during signal transmission, thereby reducing the electrical loss during transmission, while enhancing the electrical transmission speed of the first electrical terminal 41 and the second electrical terminal 42, and reducing the risk of poor contact. The thickness of the first signal terminal is greater than the thickness of the second signal terminal, and the first signal terminal is placed between the two second signal terminals, which increases the contact area between the signal terminals, improves the reliability and stability of signal transmission, effectively reduces the attenuation and reflection of the signal during the transmission of the first signal terminal and the second signal terminal, and ensures the integrity of the signal. A positioning piece is arranged on the male end body, which is used to be plugged and fixedly connected with the positioning sleeve fixed on the female end body, so as to ensure that the male end connection module and the female end connection module can be accurately aligned during installation, and at the same time enhance the stability of the connection and avoid the interruption of current and electrical signal transmission caused by loose connection.
