When the male and female terminals are mated, the end points of the S-shaped terminal contact portion will collide with each other, and then each will slide to the final contact position. During this process, the terminal will have a relatively large elastic deformation, which requires the exposed elastic part of the terminal to have a strong resistance to yielding to ensure stable matching in the final mutual contact form. This is not conducive to maintaining stable contact between the terminals, especially after long-term use, the strength performance of the terminal is easily attenuated, affecting the normal connection of the terminal.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection content of this application.

[0046] The first direction, the second direction, and the third direction defined in this application are all Figure 1 Based on which Figure 1 The X direction shown in the figure is the first direction, the Y direction perpendicular to the X direction is the second direction, and the Z direction perpendicular to the X direction and the Y direction is the third direction.

[0047] The terminals of traditional connectors generally use an S-shaped terminal contact portion. When the female end and the male end are mated with each other, the endpoints of the S-shaped contact portion will conflict with each other. At this time, the contact portions of the female end and the male end are connected with two contact endpoints, which has good contact stability. However, in this process, the terminals will have a large degree of elastic deformation, which puts higher requirements on the terminal's ability to resist drop.

[0048] The applicant has found that the conventional S-shaped contact portion is prone to attenuation of terminal strength performance after long-term use, which eventually leads to instability of the mutual mating connection, that is, poor contact.

[0049] In order to solve this problem, the present application provides a connector, see Figure 1 , Figure 1 It is a schematic structural diagram of an implementation scheme of a connector of the present application.

[0050] The connector includes a female connector 1a and a male connector 1b for mutual mating.

[0051] The female connector 1a at least includes a plurality of female terminal groups 10a evenly spaced along the third direction and a female plastic part 20a for fixing the female terminal groups 10a. Each female terminal group 10a includes a plurality of female terminals 100a evenly spaced along the second direction.

[0052] The male connector 1b includes at least a plurality of male terminal groups 10b evenly spaced along the third direction and a male plastic part 20b for fixing the male terminal groups 10b. Each male terminal group 10b includes a plurality of male terminals 100b evenly spaced along the second direction, and each male terminal 100b corresponds to each female terminal 100a.

[0053] When the female connector 1a and the male connector 1b are mated with each other, the corresponding male terminals 100b and female terminals 100a are in contact to achieve electrical connection.

[0054] In order to avoid excessive elastic deformation of the male terminal 100b and the female terminal 100a when mating with each other, please refer to Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of an embodiment of the present application in which the male terminal and the female terminal are not connected to each other. Figure 3 It is a structural schematic diagram of an implementation method of the male terminal and the female terminal of the present application in the docking state.

[0055] In this embodiment, the male terminal 100b and the female terminal 100a both include a mounting section 101, a contact section 102 extending along a first direction at one end of the mounting section 101, and a connecting section 103 for connecting the contact section 102 and the mounting section 101. The contact section 102 includes a first surface 1021 and a second surface 1022 arranged opposite to each other.

[0056] The mounting section 101 is used for fixed mounting of the male terminal 100b and the female terminal 100a, and the first surface 1021 of the contact section 102 is a contact surface for mutual mating contact.

[0057] The first surfaces 1021 of the male terminal 100b and the female terminal 100a are both provided with contact portions 104, and the contact portions 104 of the male terminal 100b and the female terminal 100a can be staggered with each other during the mutual matching process without affecting the smooth mutual matching.

[0058] When mated, the contact portion 104 of the male terminal 100b abuts against the first surface 1021 of the female terminal 100a, and the contact portion 104 of the female terminal 100a abuts against the first surface 1021 of the male terminal 100b, thereby achieving electrical connection between the two.

[0059] The biggest difference between the contact segment 102 structure of the terminal in this embodiment and the traditional S-shaped contact portion is that this embodiment adopts a linear contact segment 102 and only has one contact portion 104 protruding from the contact segment 102 .

[0060] It can be understood that, compared with the traditional terminal structure, the interfitting design of this structure has a smaller elastic deformation of the terminal contact section 102, and only needs to rotate a corresponding angle under the action of the contact portion 104, while ensuring a stable connection between the two terminals; in addition, since the terminal contact section 102 has only one contact portion 104 and the remaining sections have no bending design, the length of the terminal contact section 102 can be shortened, which helps to reduce the impact of the antenna effect.

[0061] In the present embodiment, in order to ensure smooth mating between the female terminal 100a and the male terminal 100b and avoid mutual interference between the contact portions 104 of the mating female terminal 100a and the male terminal 100b, the contact portion 104 is located on one side of the first surface 1021, and in the width direction of the contact segment 102, that is, the second direction, the extended width of the contact segment 102 is less than half of the width of the retreat segment 105, wherein the retreat segment 105 is an extended portion corresponding to the contact segment 102 and the contact portion 104 in the first direction.

[0062] It can be understood that since the width of the contact portion 104 is less than half the width of the retreat section 105, the retreat section 105 can accommodate two contact portions 104 at the same time in the width direction, so that when the contact portions 104 of the mating female terminal 100a and the male terminal 100b move relative to each other along the first direction for docking, the pair of contact portions 104 do not interfere with each other, thereby ensuring smooth docking.

[0063] In other embodiments, the width of the contact portion 104 may also be equal to half the width of the retreat section 105, the contact portion 104 may also be set at other positions, and multiple contact portions 104 may also be set on a single terminal. It is only necessary to ensure that there is no overlapping area in the orthographic projections of the contact portions 104 of the mating female terminal 100a and the male terminal 100b on the plane perpendicular to the first direction, and the effect of the present embodiment can be achieved.

[0064] In order to further improve the smoothness during mutual mating and prevent the butt-jointed end faces of the contact segments 102 of the male terminal 100b and the female terminal 100a from abutting against each other and affecting the butt-jointed connection, in this embodiment, the butt-jointed end of the contact segment 102 is provided with a guide portion 106 including a guide surface 1061. The distance between the points on the guide surface 1061 and the first surface 1021 gradually increases in the direction away from the mounting segment 101.

[0065] It can be understood that, due to the guiding effect of the guide surface 1061 , the butt end can be effectively guided to the contact portion 104 , thereby effectively improving the smoothness during butt connection.

[0066] Furthermore, since the contact portion 104 protrudes from the first surface 1021, during docking, the end of the contact segment 102 of the male terminal 100b needs to slide through the contact portion 104 of the female terminal 100a, and the end of the contact segment 102 of the female terminal 100a needs to slide through the contact portion 104 of the male terminal 100b. To ensure smoothness during docking, the outer ends of the contact portions 104 in the first direction smoothly transition to the first surface 1021, so that the ends of the contact segment 102 can smoothly slide through the contact portion 104 to reach the contact position.

[0067] Also, see Figure 4 and Figure 5 , Figure 4 This is a structural schematic diagram of the male terminal 100b and the female terminal 100a of the present application in another perspective when they are not connected. Figure 5 It is a structural schematic diagram of the male terminal 100b and the female terminal 100a of the present application in the docking state from another perspective.

[0068] As shown in the figure, in order to avoid the problem of mutual interference between the male terminal 100b and the female terminal 100a when they are connected, the contact sections 102 of the male terminal 100b and the female terminal 100a that match each other also form an angle relative to the plane where the mounting section 101 is located, and the inclination directions of the contact sections 102 of the male terminal 100b and the female terminal 100a are opposite, thereby providing a sliding space to avoid interference between the end faces of the contact sections 102 of the two terminals.

[0069] Specifically, Figure 4 and Figure 5 As shown, the contact section 102 forms an angle α greater than 1° with the plane where the mounting section 101 is located before docking, and forms an angle β no greater than 15° with the plane where the mounting section 101 is located after docking.

[0070] If the angle α between the two contact segments 102 before docking is less than 1°, the end faces of the contact segments 102 at both ends will be damaged during the docking process, while an excessively large angle will cause an unstable connection.

[0071] It is understandable that in other embodiments, the angle formed by a pair of terminal contact sections 102 that are connected to each other may also be selected according to the specific size of the terminal and the specific size of the contact portion 104, and the effect of this embodiment can be achieved.

[0072] In addition, in order to ensure stable docking, during mutual docking, contact A on contact segment 102 first contacts contact portion 104 of the other terminal. When the mutual docking is completed, contact B on contact segment 102 contacts contact portion 104 of the other terminal to maintain a stable connection state. The distance between contact A and contact B is greater than 1 mm and less than or equal to 3 mm, thereby ensuring the docking distance between the two terminals during docking and avoiding excessive friction.

[0073] At the same time, the distance between the contact point C on the contact portion 104 of the female terminal 100a and the male terminal 100b for contacting the contact segment 102 and the inner end of the contact segment 102 is greater than half the length of the contact segment 102, thereby ensuring a sufficient friction distance.

[0074] In order to prevent excessive force between the female terminal 100a and the male terminal 100b during docking, thereby avoiding scratching the surface of the terminal contact section 102, the contact portion 104 in this embodiment can also be bent as a whole along the direction from the second surface 1022 to the first surface 1021.

[0075] Specifically, Figure 2 and Figure 3 As shown, a slot 107 extending along a first direction is included between the contact portion 104 and the contact segment 102 . The slot 107 penetrates the contact segment 102 along a direction from the first surface 1021 to the second surface 1022 , so that the contact portion 104 can be bent into shape as a whole.

[0076] It is understandable that, since the contact portion 104 is integrally formed, it is avoided to add a protrusion on the first surface 1021, reducing the overall weight and strength of the contact segment 102, and avoiding excessive resistance when mating. It should be understood that the slot 107 defined in this embodiment can be a through slot or a section, as long as the contact portion 104 can be bent and formed as a whole.

[0077] In another embodiment, see Figure 6 and Figure 7 , Figure 6 1 is a schematic structural diagram of another embodiment of the present invention in which the male terminal 100b and the female terminal 100a are not connected to each other. Figure 7 It is a structural schematic diagram of another embodiment of the docking state of the male terminal 100b and the female terminal 100a of the present application.

[0078] In order to further reduce the contact force exerted by the contact portion 104 between the female terminal 100a and the male terminal 100b on each other, a notch 108 located on the inner side of the contact portion 104 in the first direction is opened on the contact section 102, and the notch 108 is connected to the contact portion 104, so that the contact portion 104 includes a fixed end 1041 and a free end 1042 arranged opposite to each other in the first direction, the fixed end 1041 is connected to the contact section 102, and the free end 1042 is adjacent to the mounting section 101 relative to the fixed end 1041.

[0079] It is understandable that since one end of the contact portion 104 is freely set and a gap 108 is provided between the contact section 102, the contact section 102 can have better elasticity while ensuring the stability of the docking connection, reduce the resistance during docking, and also protect the surface of the contact section 102.

[0080] See also Figure 8 and Fig. 9 , Figure 8 1 is a schematic structural diagram of an embodiment of a female terminal assembly 10a of the present application. Fig. 9 It is a structural schematic diagram of an implementation mode of a male terminal set 10b of the present application.

[0081] The female terminal group 10a and the male terminal group 10b both include an insulator 200a / 200b, the mounting section 101 of the female terminal 100a and the male terminal 100b is fixed in the insulator 200a / 200b, the contact section 102 extends out of the insulator 200a / 200b, and the connecting section 103 is partially exposed from the insulator 200a / 200b to connect the mounting section 101 and the contact section 102.

[0082] The insulator 200a / 200b is designed to be integrally formed, and can be made of plastic material and integrally formed by injection molding.

[0083] The female terminal 100a and the male terminal 100b each include a plurality of ground terminals 1000a / 1000b arranged at intervals along the second direction and a plurality of signal terminals 2000a / 2000b arranged at intervals between adjacent ground terminals 1000a / 1000b along the second direction.

[0084] Specifically, in this embodiment, two signal terminals 2000a / 2000b are disposed between adjacent ground terminals 1000a / 1000b, and the two signal terminals 2000a / 2000b form a signal pair.

[0085] A conductive shielding plate 300a / 300b is disposed on one side of the insulator 200a / 200b. The conductive shielding plate 300a / 300b is made of metal and is connected to the ground terminal 1000a / 1000b via a connection structure that passes through the insulator 200a / 200b.

[0086] It can be understood that the conductive shielding plate 300a / 300b connects the mounting sections 101 of all the grounding terminals 1000a / 1000b, thereby achieving unified grounding and improving crosstalk.

[0087] To ensure the signal interference shielding effect, the extension length of the ground terminal 1000a / 1000b in the second direction is greater than the extension length of the signal terminal 2000a / 2000b in the second direction. In this embodiment, the width of the ground terminal 1000a / 1000b is greater than the width of the signal terminal 2000a / 2000b.

[0088] However, since the width of the ground terminal 1000a / 1000b is relatively wide, the strength of the ground terminal 1000a / 1000b and the signal terminal 2000a / 2000b is different, resulting in uneven force when a pair of terminal groups are connected to each other, affecting stability.

[0089] Therefore, please refer to Fig.10 and Fig.11 , Fig.10This is a schematic diagram of the structure of an embodiment of the female terminal assembly of the present application after removing the insulator and the conductive shielding plate. Fig.11 It is a schematic structural diagram of an embodiment of a male terminal set of the present application after removing the insulator and the conductive shielding plate.

[0090] The ground terminal 1000a / 1000b is provided with two strip holes 1023 arranged at intervals along the second direction, and the strip holes 1023 are extended along the first direction, so that the extension length of the ground terminal 1000a / 1000b and the strip holes 1023 corresponding to the second direction is the same as the extension length of the signal terminal 2000a / 2000b in the second direction, that is, the width of the ground terminal 1000a / 1000b after removing the strip holes 1023 is the same as the width of the signal terminal 2000a / 2000b, thereby ensuring that the strength of the two are matched and the force is evenly distributed.

[0091] It is understandable that in other embodiments, other numbers of strip holes 1023 may be provided, or other forms of hollowing may be used, such as evenly distributed holes, etc. As long as the strength matching of the ground terminal 1000a / 1000b and the signal terminal 2000a / 2000b can be achieved, the effect of this embodiment can be achieved.

[0092] See also Fig.12 , Fig.12 It is a schematic structural diagram of another embodiment of the female terminal assembly of the present application after removing the insulator.

[0093] In the female terminal set 10a, since the width of the ground terminal 1000a is wider than that of the signal terminal 2000a, in order to solve the problem that the support force of the cantilever of the connecting section 103 of the ground terminal 1000a exposed outside the insulator 200a / 200b is consistent with the support force of the cantilever of the connecting section 103 of the signal terminal 2000a, the connecting section 103 of the ground terminal 1000a is narrowed, that is, the extension length of the connecting section 103 of the ground terminal 1000a and the signal terminal 2000a in the second direction is ensured to be the same, so that the support force of the cantilever of the ground terminal 1000a and the signal terminal 2000a is the same, and the force uniformity of each terminal during the docking process is further ensured.

[0094] It is understandable that in other embodiments, the cantilever of the connecting section 103 of the ground terminal 1000b in the male terminal group 10b can be narrowed so that the extension lengths of the ground terminal 1000b and the signal terminal 2000b of the male terminal group 10b in the second direction are the same, which can further ensure that the force applied to each terminal in the male terminal group 10b is uniform and consistent during the docking process.

[0095] like Fig.12As described above, in the female terminal assembly 10a, since the insulator 200a is made of plastic material and is integrally molded outside, in order to make the cantilever of the connecting section 103 of the ground terminal 1000a and the signal terminal 2000a more closely combined with the insulator 200a and facilitate the plastic to flow evenly to each surface of the terminal during molding, a through hole 1031 is opened on the connecting section 103 of the ground terminal 1000a and the signal terminal 2000a.

[0096] It is understandable that in other embodiments, holes may be provided on the connecting sections 103 of the ground terminal 1000b and the signal terminal 2000b of the male terminal set 10b to improve the structural uniformity of the male terminal set 10b during molding.

[0097] See also Fig.13 and Fig.14 , Fig.13 This is a schematic diagram of the structure of a connector in a state not yet connected to a connector according to an embodiment of the present application. Fig.14 It is a schematic diagram of the docking state structure of an embodiment of the connector of the present application.

[0098] As shown in the figure, the contact sections 102 of the female terminals 100a in the same terminal group in the female connector 1a have the same inclination angle, and the contact sections 102 of the female terminals 100a in adjacent terminal groups have opposite inclination directions, thereby forming a first figure eight structure 400.

[0099] The contact sections 102 of the female terminals 100a in the same terminal group in the female connector 1a have the same inclination angle, and the contact sections 102 of the female terminals 100a in adjacent terminal groups have opposite inclination directions, thereby forming a second figure-eight structure 500 .

[0100] When the male connector 1b and the female connector 1a are mated with each other, the second figure-eight structure 500 of the male connector 1b is inserted into the first figure-eight structure 400 of the female connector 1a, and pushes the first figure-eight structure 400 outward to open.

[0101] It can be understood that when a pair of terminal groups of the male connector 1b are mated with a pair of terminal groups of the female connector 1a, the contact portion 104 of the terminal of the male connector 1b abuts against the contact segment 102 of the terminal of the female connector 1a and is pushed outward until reaching the plug-in position. At this time, the two female terminal groups 10a of the female connector 1a forming the first figure-eight structure 400 clamp the two male terminal groups 10b of the male connector 1b forming the second figure-eight structure 500 in the middle to ensure the stability of the connection.

[0102] When the two female terminals 100a of the first figure-eight structure 400 are connected to each other, they are subjected to an outward force. In order to support the contact section 102 of the female terminal 100a, a first support block 201 is provided on one end face of the insulator 200a / 200b close to the contact section 102. The first support block 201 is arranged on the force-bearing back side of the contact section 102 of the corresponding female terminal 100a, thereby providing effective support.

[0103] Similarly, when the two male terminals 100b of the second figure-eight structure 500 of the male terminal 100b are mated and connected, they are subjected to an inward pressing force. In order to support the contact section 102 of the male terminal 100b, a second support block 202 is provided on one end face of the insulator 200a / 200b close to the contact section 102. The second support block 202 is arranged on the force-bearing back side of the contact section 102 of the corresponding male terminal 100b, thereby providing effective support.

[0104] It is worth noting that the above-mentioned embodiment is only a preferred embodiment of the present application in order to ensure docking stability. In other embodiments, the inclination direction and angle of the female terminal 100a and the male terminal 100b of the female connector 1a and the male connector 1b can also be adopted in other ways to achieve docking between the two.

[0105] The above are merely embodiments of the present application, and are not intended to limit the scope of patent protection of the present application. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of the present application.
