Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and in particular to a mating connector. Background Technology

[0002] A connector is a widely used electronic component that allows current to flow through a circuit that is blocked or isolated. The male and female terminals can transmit information or current when they come into contact.

[0003] Currently, the female terminal in the connector transmits current by forming a cantilever beam structure through a slot. However, during the mating process of the male and female terminals, the cantilever beam structure of the female terminal is easily misaligned, resulting in permanent plastic deformation and thus failure of contact between the male and female terminals. Utility Model Content

[0004] The purpose of this invention is to provide a mating connector whose male and female terminals can be mated more precisely, effectively avoiding contact failure caused by misaligned insertion.

[0005] To achieve the above objectives, this utility model provides a mating connector, comprising:

[0006] The female terminal includes a female end core, a female end body, a cage spring, and a retaining ring, all coaxial along a first direction. The female end core has a first accommodating space, and one end of the female end core has a first insertion interface communicating with the first accommodating space. The female end body is installed within the first accommodating space, and the end face of the female end body near the first insertion interface has a first insertion groove extending inwards. The cage spring and the retaining ring are sequentially embedded in the first insertion groove along the first direction, with the retaining ring abutting against the cage spring. The inner diameter of the retaining ring is the same as the inner diameter of the cage spring.

[0007] The male terminal includes a male end core and a male end body coaxial along a first direction; the male end core has a second accommodating space, and a second insertion interface communicating with the second accommodating space is opened at the center of one end of the male end core; the male end body is installed in the second accommodating space, and the end of the male end body near the second insertion interface is the insertion end, and the outer diameter of the insertion end is the same as the inner diameter of the retaining ring.

[0008] Preferably, the first insertion slot includes a mounting slot and a skirt slot that are sequentially connected along a first direction. The mounting slot and the skirt slot are coaxial. The diameter of the mounting slot is smaller than the diameter of the skirt slot. The skirt slot extends through to the end face of the female end body near the first insertion interface.

[0009] The cage spring is embedded in the mounting groove;

[0010] The retaining ring includes an annular portion and a first extension portion. The first extension portion is circumferentially arranged along one end edge of the annular portion. The outer diameter of the first extension portion is larger than the outer diameter of the annular portion. The inner diameter of the first extension portion is the same as the inner diameter of the annular portion. The first extension portion is embedded in the skirt groove. The annular portion is embedded in the mounting groove and abuts against the cage spring. The inner diameter of the annular portion is the same as the inner diameter of the cage spring.

[0011] Preferably, the first insertion slot further includes a limiting slot, the limiting slot being connected to the mounting slot in the opposite direction of the first direction, the limiting slot and the mounting slot being coaxial, the diameter of the limiting slot being smaller than the diameter of the mounting slot, and the limiting slot being fitted with the insertion end of the male end body.

[0012] Preferably, the male terminal further includes an anti-contact cap, which is installed at the insertion end of the male terminal body.

[0013] Preferably, a second insertion groove is provided inwardly at the center of the end face of the insertion end of the male end body;

[0014] The bottom center of the first insertion slot has a mounting hole extending in the opposite direction to the first direction, and the diameter of the mounting hole is smaller than the diameter of the first insertion slot.

[0015] The female terminal also includes an anti-contact pin 6, which extends along a first direction. The first end of the anti-contact pin 6 is embedded in the mounting hole, and the second end of the anti-contact pin 6 extends sequentially along the first direction to the first insertion slot and the first insertion interface. The anti-contact pin 6 and the second insertion slot are fitted together.

[0016] Preferably, the male terminal further includes an anti-contact cap, which is installed on the insertion end of the male terminal body. The anti-contact cap has a through insertion hole in its center, and the insertion hole is coaxially connected to the second insertion slot.

[0017] The anti-contact pin 6 fits into the insertion hole and the second insertion slot.

[0018] Preferably, the female end of the rubber core has an opening at the end away from the first insertion interface that communicates with the first accommodating space, and the male end of the rubber core has an opening at the end away from the second insertion interface that communicates with the second accommodating space. The inner sidewalls of both the female end and the male end are provided with mounting platforms, and the inner diameters of the two mounting platforms are the same as the outer diameters of the corresponding female end body and the male end body, respectively.

[0019] Both the female end body and the male end body have circumferentially arranged positioning grooves on their outer side walls, and elastic retaining rings are fitted inside the positioning grooves.

[0020] Preferably, the outer walls of both the female end core and the male end core are provided with circumferentially arranged limiting portions. The limiting portions are located on the side of the positioning groove near the opening. The outer diameter of the limiting portions is larger than the inner diameter of the mounting platform. The distance between the limiting portions and the positioning groove in the first direction is not less than the length of the mounting platform in the first direction.

[0021] Preferably, the elastic retaining ring is C-shaped.

[0022] Preferably, a mounting shell is detachably installed on the outer side of both the female end rubber core and the outer side of the male end rubber core along the circumferential direction, and the mounting shell has protrusions on both outer side walls in the second direction;

[0023] The mating connector further includes two frames, each corresponding to a mounting shell. Each frame includes an upper clamping frame and a lower clamping frame, both of which are annular. The upper clamping frame is detachably mounted on the top of the lower clamping frame. The upper clamping frame has a first fixing hole on each of its two outer sidewalls in the second direction, extending to the bottom surface of the upper clamping frame. The lower clamping frame has a second fixing hole on each of its two outer sidewalls in the second direction, extending to the top surface of the lower clamping frame. The second fixing hole and the corresponding first fixing hole communicate to form a space for clamping the protrusion.

[0024] The first direction and the second direction intersect each other perpendicularly.

[0025] Compared with the prior art, the beneficial effects of this plug-in connector according to the present invention are as follows:

[0026] The female end body is installed in the first accommodating space of the female end core, and the male end body is installed in the second accommodating space of the male end core. A first insertion interface communicating with the first accommodating space is provided on one side of the female end core, and this first insertion interface is used to connect with the male end body. A second insertion interface communicating with the second accommodating space is provided on one side of the male end core, and this second insertion interface is used to connect with the female end core.

[0027] When the male end of the main body is inserted into the first connector, the female end insert is also inserted into the second connector. After the male end of the main body is inserted into the first connector, it is immediately inserted into the first insertion slot of the female end of the main body. Since the outer diameter of the insertion end and the inner diameter of the retaining ring are the same, if the insertion direction of the insertion end is correct, it will be smoothly inserted into the inner hole of the retaining ring.

[0028] Since the inner diameter of the retaining ring is the same as that of the cage spring, and the retaining ring abuts against the cage spring for fixation, after the insertion end of the male body is smoothly inserted into the inner hole of the retaining ring, the retaining ring limits the insertion direction of the insertion end, so that the insertion end can be smoothly inserted into the inner hole of the cage spring without damaging the cage spring and causing deformation, and the cage spring can contact the outer peripheral wall of the insertion end of the male body to transmit current.

[0029] The structure of the male and female terminals in this application enables more precise mating of the male and female terminals, effectively avoiding contact failure caused by misaligned insertion. Attached Figure Description

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0048] like Figure 1-5As shown in Figures 8-11, a mating connector according to an embodiment of the present invention includes: a female terminal 1 and a male terminal 7;

[0049] The female terminal 1 includes a female terminal core 2, a female terminal body 3, a cage spring 4, and a retaining ring 5, which are coaxial along the first direction X. The female terminal core 2 is provided with a first accommodating space 21, and a first insertion interface 22 communicating with the first accommodating space 21 is opened at the center of one end of the female terminal core 2. The female terminal body 3 is installed in the first accommodating space 21, and a first insertion groove 31 is opened inward from the center of the end face of the female terminal body 3 near the first insertion interface 22. The cage spring 4 and the retaining ring 5 are sequentially embedded in the first insertion groove 31 along the first direction X. The retaining ring 5 abuts against the cage spring 4, and the inner diameter of the retaining ring 5 is the same as the inner diameter of the cage spring 4.

[0050] The male terminal 7 includes a male terminal core 8 and a male terminal body 9 coaxial along the first direction X; the male terminal core 8 is provided with a second accommodating space 81, and a second insertion interface 82 communicating with the second accommodating space 81 is opened at the center of one end of the male terminal core 8; the male terminal body 9 is installed in the second accommodating space 81, and the end of the male terminal body 9 near the second insertion interface 82 is the insertion end, and the outer diameter of the insertion end is the same as the inner diameter of the retaining ring 5.

[0051] It should be noted that the female end body 3 is installed in the first accommodating space 21 of the female end core 2, and the male end body 9 is installed in the second accommodating space 81 of the male end core 8. A first insertion interface 22 communicating with the first accommodating space 21 is provided on one side of the female end core 2, and the first insertion interface 22 is used to connect with the male end body 9. A second insertion interface 82 communicating with the second accommodating space 81 is provided on one side of the male end core 8, and the second insertion interface 82 is used to connect with the female end core 2.

[0052] When the insertion end of the male body 9 is inserted into the first insertion interface 22, the female core 2 is also inserted into the second insertion interface 82. After the insertion end of the male body 9 is inserted into the first insertion interface 22, it is immediately inserted into the first insertion groove 31 of the female body 3. Since the outer diameter of the insertion end is the same as the inner diameter of the retaining ring 5, if the insertion direction of the insertion end is correct, it will be smoothly inserted into the inner hole of the retaining ring 5.

[0053] Since the inner diameter of the retaining ring 5 is the same as the inner diameter of the cage spring 4, and the retaining ring 5 abuts against the cage spring 4 for fixation, after the insertion end of the male body 9 is smoothly inserted into the inner hole of the retaining ring 5, the retaining ring 5 limits the insertion direction of the insertion end, so that the insertion end can be smoothly inserted into the inner hole of the cage spring 4 without damaging the cage spring 4 and causing deformation, and the cage spring 4 can contact the outer peripheral wall of the insertion end of the male body 9 to transmit current.

[0054] The structure of the male and female terminals 1 in this application enables more precise mating of the male and female terminals 1, effectively avoiding contact failure caused by misaligned mating.

[0055] In existing technologies, the female terminal 1 transmits current by forming a cantilever beam structure through slots. This requires the female terminal body 3 to be made of a highly elastic material, typically tin bronze or phosphor bronze, which have low conductivity. However, this application transmits current by using a cage spring 4, which eliminates the requirement for the female terminal body 3 to be made of a highly elastic material. Therefore, a material with higher conductivity, such as copper, can be selected, improving the connector's conductivity.

[0056] The gap between the inner side of the retaining ring 5 and the outer side of the insertion end of the male body 9 is preferably 0.05 to 0.1 mm. The retaining ring 5 can limit the insertion end of the male body 9 while avoiding excessive contact.

[0057] like Figure 1 , 8 As shown, in this embodiment, the first insertion groove 31 further includes a mounting groove 312 and a skirt groove 311 that are connected sequentially along the first direction X. The mounting groove 312 and the skirt groove 311 are coaxial. The diameter of the mounting groove 312 is smaller than the diameter of the skirt groove 311. The skirt groove 311 extends through to the end face of the female end body 3 near the first insertion interface 22.

[0058] The cage spring 4 is embedded in the mounting groove 312;

[0059] The retaining ring 5 includes an annular portion 52 and a first extension portion 51. The first extension portion 51 is circumferentially arranged along one end edge of the annular portion 52. The outer diameter of the first extension portion 51 is larger than the outer diameter of the annular portion 52. The inner diameter of the first extension portion 51 is the same as the inner diameter of the annular portion 52. The first extension portion 51 is embedded in the skirt groove 311. The annular portion 52 is embedded in the mounting groove 312 and abuts against the cage spring 4. The inner diameter of the annular portion 52 is the same as the inner diameter of the cage spring 4.

[0060] It should be noted that the retaining ring 5 includes an annular portion 52 and a first extension portion 51. The first extension portion 51 is circumferentially arranged along one end edge of the annular portion 52 and has a larger outer diameter. Therefore, the first extension portion 51 can overlap the step formed by the skirt groove 311 and the mounting groove 312, so that the first extension portion 51 is embedded in the skirt groove 311, the annular portion 52 is embedded in the mounting groove 312 and abuts against the cage spring 4 embedded in the mounting groove 312, preventing the cage spring 4 from moving upward, and realizing the stable installation of the retaining ring 5 and the cage spring 4 in the first insertion groove 31.

[0061] The inner diameter of the first extension 51 is the same as the inner diameter of the annular portion 52. This ensures that when the insertion end of the male end body 9 is inserted into the inner hole of the first extension 51 and the inner hole of the annular portion 52 of the retaining ring 5, the inner sidewalls of the first extension 51 and the annular portion 52 can jointly support the insertion end of the male end body 9, effectively ensuring the correct insertion direction of the insertion end of the male end body 9.

[0062] The inner diameter of the annular portion 52 is the same as the inner diameter of the cage spring 4, which ensures that when the insertion end of the male body 9 is inserted into the inner hole of the cage spring 4 after passing through the inner hole of the annular portion 52, the cage spring 4 can make close contact with the insertion end of the male body 9. Each coil of the cage spring 4 can effectively contact the insertion end of the male body 9 to generate positive pressure. The contact area between the cage spring 4 and the insertion end of the male body 9 is large, which can improve the current transmission effect.

[0063] like Figure 1 , 8 As shown, in this embodiment, the first insertion groove 31 further includes a limiting groove 313. The limiting groove 313 is connected to the mounting groove 312 in the opposite direction of the first direction X. The limiting groove 313 and the mounting groove 312 are coaxial. The diameter of the limiting groove 313 is smaller than the diameter of the mounting groove 312. The limiting groove 313 and the insertion end of the male end body 9 are matched.

[0064] It should be noted that a coaxial limiting groove 313 is connected in the opposite direction of the first direction X of the mounting groove 312, and the diameter of the limiting groove 313 is smaller than the diameter of the mounting groove 312. The limiting groove 313 and the insertion end of the male body 9 are matched. When the insertion end of the male body 9 is inserted into the first insertion groove 31, the insertion end passes through the inner hole of the retaining ring 5 and the inner hole of the cage spring 4 in sequence, and is then limited by the limiting groove 313, thereby improving the stability of the insertion end in the first insertion groove 31.

[0065] The cage spring 4 is embedded in the mounting groove 312 and is installed on the step formed by the mounting groove 312 and the limiting groove 313. The step and the retaining ring 5 together fix the cage spring 4.

[0066] like Figure 4-5 As shown, in this embodiment, the male terminal 7 further includes an anti-touch cap 10, which is installed at the insertion end of the male terminal body 9.

[0067] It should be noted that the insertion end of the male terminal body 9 is equipped with a protective cap 10. The gap between the protective cap 10 and the second connector 82 is insufficient for the operator's fingers to pass through, effectively preventing the operator from touching the live male terminal body 9 with their fingers passing through the second connector 82 when holding the male terminal 7. Figure 7 ).

[0068] The male end of the main body 9 has a groove that matches the anti-contact cap 10, allowing the anti-contact cap 10 to be stably installed on the insertion end. The anti-contact cap 10 is made of plastic, which can effectively insulate against electric shock.

[0069] like Figure 1 , 8As shown, further, when the first insertion groove 31 includes the aforementioned limiting groove 313, mounting groove 312 and skirt groove 311 connected sequentially along the first direction X, the anti-contact cap 10 is inserted into the limiting groove 313, thereby ensuring that the cage spring 4 embedded in the mounting groove 312 can contact the outer peripheral wall of the male end body 9 for current transmission.

[0070] like Figure 1-3 As shown in Figures 8 and 10, in this embodiment, a second insertion groove 91 is further provided inwardly at the center of the end face of the insertion end of the male end body 9.

[0071] The bottom center of the first insertion groove 31 has a mounting hole 32 extending in the opposite direction of the first direction X. The diameter of the mounting hole 32 is smaller than the diameter of the first insertion groove 31.

[0072] The female terminal 1 also includes an anti-contact pin 6, which extends along the first direction X. The first end of the anti-contact pin 6 is embedded in the mounting hole 32, and the second end of the anti-contact pin 6 extends along the first direction X to the first insertion groove 31 and the first insertion interface 22 in sequence. The anti-contact pin 6 and the second insertion groove 91 are matched.

[0073] It should be noted that the female terminal 1 also includes an anti-contact pin 6, which extends along the first direction X. The first end of the anti-contact pin 6 is embedded in the mounting hole 32, and the second end of the anti-contact pin 6 extends sequentially along the first direction X to the first insertion slot 31 and the first insertion interface 22. The gap between the first insertion interface 22 and the anti-contact pin 6 is insufficient for the operator's fingers to pass through, thereby effectively preventing the operator from touching the live female terminal body 3 by passing through the first insertion interface 22 when holding the female terminal 1. Figure 6 ).

[0074] To allow the female terminal 1 and male terminal 7 to be smoothly inserted, the diameter of the mounting hole 32 is smaller than the diameter of the first insertion groove 31. This creates a gap between the anti-contact pin 6 embedded in the mounting hole 32 and the inner wall of the first insertion groove 31, allowing the insertion end of the male terminal body 9 to be inserted into the first insertion groove 31. The center of the end face of the insertion end of the male terminal body 9 is provided with a second insertion groove 91. When the insertion end of the male terminal body 9 is inserted into the first insertion groove 31, the anti-contact pin 6 will also be inserted into the second insertion groove 91, thus achieving smooth insertion of the male and female terminals 1.

[0075] The head of the anti-contact needle 6 is injection-molded with a plastic cap, or the material of the anti-contact needle 6 is plastic, which can effectively insulate against electric shock.

[0076] like Figure 1 , 8 As shown in Figures 1 and 10, in this embodiment, the male terminal 7 further includes an anti-touch cap 10, which is installed on the insertion end of the male terminal body 9. The center of the anti-touch cap 10 has a through insertion hole 101, which is coaxially connected to the second insertion groove 91.

[0077] The anti-contact pin 6 fits into the insertion hole 101 and the second insertion slot 91.

[0078] It should be noted that when the female terminal 1 is equipped with the anti-contact pin 6, since the anti-contact cap 10 is installed at the insertion end of the male terminal body 9, in order to allow the male and female terminals 1 to be inserted smoothly, the center of the anti-contact cap 10 is provided with a through insertion hole 101. The insertion hole 101 is coaxially connected to the second insertion groove 91, so that the anti-contact pin 6 can pass through the insertion hole 101 and enter the second insertion groove 91.

[0079] like Figure 8-12 As shown, in this embodiment, the female end core 2, which is away from the first insertion interface 22, has an opening that connects to the first accommodating space 21, and the male end core 8, which is away from the second insertion interface 82, has an opening that connects to the second accommodating space 81. The inner sidewalls of the female end core 2 and the male end core 8 are provided with a mounting platform 11, and the inner diameter of the two mounting platforms 11 is the same as the outer diameter of the corresponding female end body 3 and male end body 9.

[0080] Both the female end body 3 and the male end body 9 have circumferentially arranged positioning grooves 12 on their outer side walls, and elastic retaining rings 13 are fitted inside the positioning grooves 12.

[0081] It should be noted that the end of the female end core 2 away from the first insertion interface 22 has an opening that connects to the first accommodating space 21, so that the female end body 3 can enter the first accommodating space 21 through the opening, thereby realizing the assembly of the female end core 2 and the female end body 3.

[0082] When the female end body 3 enters the first accommodating space 21, since the inner diameter of its mounting platform 11 is the same as the outer diameter of the female end body 3, it pushes the female end body 3, allowing the outer side wall of the female end body 3 to advance along the mounting platform 11. When the female end body 3 advances to the positioning groove 12 and contacts the mounting platform 11, the mounting platform 11 squeezes the elastic retaining ring 13 in the positioning groove 12. The elastic retaining ring 13 retracts completely inward into the positioning groove 12 until the female end body 3 continues to advance. When the positioning groove 12 leaves the mounting platform 11, the elastic retaining ring 13 resets outward and abuts against the inner side wall of the female end core 2, thus realizing the installation of the female end body 3 in the first accommodating space 21 of the female end core 2.

[0083] The male end of the core 8, away from the second insertion interface 82, has an opening that connects to the second accommodating space 81, so that the male end body 9 can enter the second accommodating space 81 through the opening, thereby realizing the assembly of the male end core 8 and the female end body 3.

[0084] The principle of the male end body 9 being installed in the second accommodating space 81 of the male end core 8 is the same as the principle of the female end body 3 being installed in the first accommodating space 21 of the female end core 2, and will not be repeated here.

[0085] The mounting platform 11 is formed by the vertical through-hole of the mold structure, which reduces the space occupancy rate and allows for a larger terminal space design volume, thereby improving conductivity.

[0086] like Figure 8-11 As shown, in this embodiment, the outer walls of both the female end core 2 and the male end core 8 are provided with a limiting part 19 arranged circumferentially. The limiting part 19 is located on the side of the positioning groove 12 near the opening. The outer diameter of the limiting part 19 is larger than the inner diameter of the mounting platform 11. The distance between the limiting part 19 and the positioning groove 12 in the first direction X is not less than the length of the mounting platform 11 in the first direction X.

[0087] It should be noted that a limiting part 19 is provided on the outer side wall of the positioning groove 12 near the opening. The outer diameter of the limiting part 19 is larger than the inner diameter of the mounting platform 11. The distance between the limiting part 19 and the positioning groove 12 in the first direction X is not less than the length of the mounting platform 11 in the first direction X. Thus, when the limiting part 19 abuts against the mounting platform 11, it can restrict the positions of the female end body 3 and the male end body 9 in the first accommodating space 21 and the second accommodating space 81, respectively.

[0088] Preferably, the distance between the limiting part 19 and the positioning groove 12 in the first direction X is equal to the length of the mounting platform 11 in the first direction X.

[0089] like Figure 3 , 5 As shown, in this embodiment, the elastic retaining ring 13 is further C-shaped.

[0090] It should be noted that the elastic retaining ring 13 is C-shaped, which makes it easy to remove the elastic retaining ring 13 from the positioning groove 12.

[0091] like Figure 2 , 4 As shown in 13-14, in this embodiment, the outer side of the female end core 2 and the outer side of the male end core 8 are further detachably mounted with a mounting shell 14 along the circumferential direction, and the two outer side walls of the mounting shell 14 in the second direction Y are provided with protrusions 18.

[0092] The mating connector also includes two frames 15, which correspond to two mounting shells 14 respectively. Each frame 15 includes an upper clamping frame 16 and a lower clamping frame 17. Both the upper clamping frame 16 and the lower clamping frame 17 are annular. The upper clamping frame 16 is detachably mounted on the top of the lower clamping frame 17. The upper clamping frame 16 has a first fixing hole 161 on each of its two outer side walls in the second direction Y. The first fixing hole 161 extends to the bottom surface of the upper clamping frame 16. The lower clamping frame 17 has a second fixing hole 171 on each of its two outer side walls in the second direction Y. The second fixing hole 171 extends to the top surface of the lower clamping frame 17. The second fixing hole 171 and the corresponding first fixing hole 161 communicate to form a space for clamping the protrusion 18.

[0093] Among them, the first direction X and the second direction Y intersect each other perpendicularly.

[0094] It should be noted that mounting shells 14 are detachably installed circumferentially on the outer sides of both the female end core 2 and the male end core 8. By inserting the protrusion 18 on the mounting shell 14 into the second fixing hole 171 of the lower clamping frame 17, and then closing the clamping frame 16, the protrusion 18 is clamped in the space formed by the first fixing hole 161 and the second fixing hole 171, thus fixing the upper clamping frame 16 and the lower clamping frame 17. In this way, the mounting shell 14 is fixed on the frame 15, the female end core 2 and the male end core 8 are fixed on the frame 15, and the frame 15 is installed on the housing, realizing a modular series product design. The current of this structure can reach 350A and above.

[0095] The female end rubber core 2, the male end rubber core 8, and the mounting shell 14 are detachably connected, so rubber cores with different parameters can be installed in the mounting shell 14 according to different needs.

[0096] Furthermore, the upper frame 15 has multiple first fixing holes 161 on both outer side walls in the second direction Y, and the multiple first fixing holes 161 are distributed sequentially along the third direction Z. The lower clamping frame 17 has multiple second fixing holes 171 on both outer side walls in the second direction Y, and the multiple second fixing holes 171 are distributed sequentially along the third direction Z. The first direction X, the second direction Y and the third direction Z intersect each other perpendicularly, so that multiple mounting shells 14 can be installed on the frame 15 along the third direction Z to achieve modular assembly.

[0097] The working process of this utility model is as follows: the female end body 3 is installed in the first accommodating space 21 of the female end core 2, and the male end body 9 is installed in the second accommodating space 81 of the male end core 8. A first insertion interface 22 communicating with the first accommodating space 21 is opened on one side of the female end core 2, and the first insertion interface 22 is used to connect with the male end body 9. A second insertion interface 82 communicating with the second accommodating space 81 is opened on one side of the male end core 8, and the second insertion interface 82 is used to connect with the female end core 2.

[0098] When the insertion end of the male body 9 is inserted into the first insertion interface 22, the female core 2 is also inserted into the second insertion interface 82. After the insertion end of the male body 9 is inserted into the first insertion interface 22, it is immediately inserted into the first insertion groove 31 of the female body 3. Since the outer diameter of the insertion end is the same as the inner diameter of the retaining ring 5, if the insertion direction of the insertion end is correct, it will be smoothly inserted into the inner hole of the retaining ring 5.

[0099] Since the inner diameter of the retaining ring 5 is the same as the inner diameter of the cage spring 4, and the retaining ring 5 abuts against the cage spring 4 for fixation, after the insertion end of the male body 9 is smoothly inserted into the inner hole of the retaining ring 5, the retaining ring 5 limits the insertion direction of the insertion end, so that the insertion end can be smoothly inserted into the inner hole of the cage spring 4 without damaging the cage spring 4 and causing deformation, and the cage spring 4 can contact the outer peripheral wall of the insertion end of the male body 9 to transmit current.

[0100] The structure of the male and female terminals 1 in this application enables more precise mating of the male and female terminals 1, effectively avoiding contact failure caused by misaligned mating.

[0101] In summary, this utility model provides a mating connector whose male and female terminals can be mated more accurately, effectively avoiding contact failure caused by misaligned insertion.

[0102] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
