DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] An embodiment of a USB connector of the present invention, as Figures 1 to 6 shown.

[0027] A USB connector includes a male connector 100 and a female connector 200. The male connector 100 can move toward the female connector 200 along a first direction and plug into the female connector 200. The plugging direction of the male connector 100 and the female connector 200 is called the first direction. The male connector 100 includes a first housing 110 and a plurality of male terminals 120. The plurality of male terminals 120 are sequentially arranged in a second direction in the first housing 110. The second direction is perpendicular to the first direction. The male terminals 120 are elastic, and each male terminal 120 is provided with a support member.

[0028] The female connector 200 includes a second housing 210 and a plurality of female terminals 220, wherein the plurality of female terminals 220 are sequentially arranged along the second direction in the second housing 210, and the female terminals 220 are arranged one-to-one with the male terminals 120. A plurality of limiting slideways 230 are provided in the second housing 210, wherein the limiting slideways 230 are arranged along the first direction, and the limiting slideways 230 are arranged one-to-one with the supporting members, and the supporting members can slide in the limiting slideways 230 arranged corresponding thereto.

[0029] The plugging process of the male connector 100 and the female connector 200 has a first stroke and a second stroke. In the first stroke, the support member contacts the corresponding limit slide 230 in the third direction, and the third direction is perpendicular to the first direction and the second direction respectively, and a gap is left between the female terminal 220 and the male terminal 120 in the third direction; in the second stroke, the support member leaves a gap between the corresponding limit slide 230 in the third direction, and the female terminal 220 contacts the male terminal 120 in the third direction.

[0030] In this embodiment, a support is provided on the male terminal 120, and a limit slide 230 cooperating with the support is provided on the female terminal 220. When the male connector 100 and the female connector 200 are plugged in, the support slides in the limit slide 230 corresponding to the support. In the first stroke of plugging in, the support contacts the limit slide 230 corresponding to the support, and the female terminal 220 does not contact the male terminal 120, that is, the male terminal 120 is supported by the support, and the support is used to slide instead of the male terminal 120, so that the direct friction between the male terminal 120 and the female terminal 220 is transferred between the support and the limit slide 230, so that the male terminal 120 and the female terminal 220 are prevented from always being in direct contact during the plugging process, thereby reducing the wear between the male terminal 120 and the female terminal 220, extending the service life of the male terminal 120 and the female terminal 220, reducing the problem of poor contact caused by wear, and thus improving the overall reliability and stability of the connector. Then, in the second plugging stroke, the female terminal 220 contacts the male terminal 120, and the plugging is completed, thereby ensuring the normal use of the connector.

[0031] In this embodiment, the support member includes a support block 130, and the two ends of the support block 130 along the third direction are respectively referred to as the head end and the tail end, the head end is mounted on the male terminal 120 corresponding thereto, and the tail end is suspended. The limiting slide 230 includes a first sliding section 231, a second sliding section 232, and a third sliding section 233, the first sliding section 231, the second sliding section 232, and the third sliding section 233 are sequentially connected in the first direction, and the first sliding section 231 is located on the side of the third sliding section 233 close to the male head 100 in the first direction. A transition surface 216 is provided on the second housing 210, and the transition surface 216 and the female terminal 220 are sequentially arranged in the first direction, and the transition surface 216 is located on the side of the female terminal 220 away from the male head 100 in the first direction.

[0032] When the tail end of the support block 130 slides along the first sliding section 231, the tail end of the support block 130 can abut against the first sliding section 231, and at this time, a gap is left between the male terminal 120 and the transition surface 216 in the third direction; when the tail end of the support block 130 slides along the second sliding section 232, the tail end of the support block 130 can abut against the second sliding section 232, and at this time, a gap is left between the female terminal 220 and the male terminal 120 in the third direction; when the tail end of the support block 130 slides to the third sliding section 233, a gap is left between the tail end of the support block 130 and the third sliding section 233 in the third direction, and at this time, the female terminal 220 contacts the male terminal 120 in the third direction.

[0033] Specifically, the first sliding section 231 is tilted, and the two ends of the first sliding section 231 are respectively referred to as the first end and the second end, the first end is located on the side of the second end close to the male connector 100 in the first direction, and the first end is located on the side of the second end in the third direction away from the inner wall of the second housing 210. The transition surface 216 is tilted and parallel to the first sliding section 231.

[0034] The second sliding section 232 is arranged along the first direction. The third sliding section 233 includes a transition section 234 and a connecting section 235. The transition section 234 is arranged obliquely, and the connecting section 235 is arranged along the first direction. The connecting section 235 is located on a side of the transition section 234 away from the second sliding section 232 in the first direction. The two ends of the transition section 234 are respectively referred to as the third end and the fourth end. The third end is located on a side of the fourth end close to the male connector 100 in the first direction, and the third end is located on a side of the fourth end close to the inner wall of the second housing 210 in the third direction.

[0035] During insertion, the projection of the rear end of the support block 130 along the first direction falls on the first sliding section 231 , so that the rear end of the support block 130 can abut against the first sliding section 231 .

[0036] Furthermore, two support blocks 130 are disposed on each male terminal 120 , and the two support blocks 130 are respectively disposed at two ends of the male terminal 120 in the second direction.

[0037] Furthermore, the point on the male terminal 120 used to contact the female terminal 220 is called the contact point 121, the support block 130 and the contact point 121 are located on the same axis in the second direction, and when the tail end of the support block 130 slides in the second sliding section 232, the vertical distance from the contact point 121 to the tail end of the support block 130 along the third direction is greater than the vertical distance from the contact point 121 to the female terminal 220 along the third direction, so that when the tail end of the support block 130 slides to abut against the second sliding section 232, there is a distance between the contact point 121 and the female terminal 220 in the third direction, that is, the contact point 121 does not contact the female terminal 220.

[0038] When the tail end of the support block 130 slides on the third sliding section 233, the vertical distance from the contact point 121 to the tail end of the support block 130 along the third direction is smaller than the vertical distance from the third end to the fourth end of the transition section 234, so that when the contact point 121 contacts the female terminal 220, the tail end of the support block 130 is on the transition section 234, and then the contact point 121 on the male terminal 120 slides along the female terminal 220 to complete the plug-in, and the tail end of the support block 130 is in a suspended state.

[0039] In this embodiment, by providing the support block 130, during the plugging process, the rear end of the support block 130 will contact the first sliding section 231 and move from the first end to the second end on the first sliding section 231, and at this time, a gap will be left between the male terminal 120 and the transition surface 216 in the third direction. When the rear end of the support block 130 slides to the second sliding section 232, since the vertical distance from the contact point 121 to the rear end of the support block 130 along the third direction is greater than the vertical distance from the contact point 121 to the female terminal 220 along the third direction, the contact point 121 does not contact the female terminal 220 at this time, that is, a gap will be left between the female terminal 220 and the male terminal 120 in the third direction, and the support block 130 will make the male terminal 120 move in the first housing 110 in a compressed state.

[0040] After the tail end of the support block 130 slides along the second sliding section 232 to the transition section 234 of the third sliding section 233, the tail end of the support block 130 will move along the transition section 234 in the third direction to the side away from the inner wall of the second housing 210, and the male terminal 120 is gradually released. Since the vertical distance from the contact point 121 to the tail end of the support block 130 along the third direction is less than the vertical distance from the third end to the fourth end of the transition section 234, the contact point 121 on the male terminal 120 will first contact the female terminal 220, and then the contact point 121 on the male terminal 120 will continue to slide along the female terminal 220, and a gap will be left between the tail end of the support block 130 and the connecting section 235 in the third direction. That is, the tail end of the support block 130 is in a suspended state.

[0041] In this embodiment, a first recoil cavity 111 is provided in the first shell 110, and a first pressing block 113 is connected to the first recoil cavity 111 through a first elastic member 112, and the first elastic member 112 is arranged along a first direction, and the first elastic member 112 is a spring. The first pressing block 113 can slide along a first direction in the first recoil cavity 111, and the first pressing block 113 is slidably sealed with the first recoil cavity 111. A first recoil channel 114 is provided in the first shell 110, and the first recoil channel 114 is connected with the first recoil cavity 111, and the first recoil channel 114 is arranged toward the inside of the first shell 110. The female connector 200 further includes a first plug-in block 240, and the first plug-in block 240 can abut against the first pressing block 113 and make the first pressing block 113 slide along a first direction in the first recoil cavity 111. The female terminal 220 is arranged on the first plug-in block 240. The limiting slide 230 is arranged on the first plug-in block 240.

[0042] A second recoil chamber 211 is provided in the second shell 210, and a second pressing block 213 is connected to the second recoil chamber 211 through a second elastic member 212. The second elastic member 212 is arranged along the first direction, and the second elastic member 212 is a spring. The second pressing block 213 can slide along the first direction in the second recoil chamber 211, and the second pressing block 213 is slidably sealed with the second recoil chamber 211. A second recoil channel 214 is provided in the second shell 210, and the second recoil channel 214 is connected with the second recoil chamber 211, and the second recoil channel 214 is arranged toward the inside of the second shell 210. The male connector 100 further includes a second plug block 140, and the second plug block 140 can abut against the second pressing block 213 and make the second pressing block 213 slide along the first direction in the second recoil chamber 211.

[0043] During the plugging process, after the first plug block 240 abuts against the first pressure block 113 and the second plug block 140 abuts against the second pressure block 213, as the male connector 100 continues to approach the female connector 200, the first pressure block 113 will slide along the first direction in the first recoil cavity 111, squeeze out the air in the first recoil cavity 111, and then clean the space where the female terminal 220 is located, so that some dust is blown out. At the same time, the second pressure block 213 will slide along the first direction in the second recoil cavity 211, squeeze out the air in the second recoil cavity 211, and then clean the space where the male terminal 120 is located, so that some dust is blown out. By cleaning the space where the male terminal 120 and the female terminal 220 are located, the interference of dust on the electrical connection is reduced, and the stability of the connection is improved.

[0044] In this embodiment, the head end of the support block 130 can rotate around the second direction on the male terminal 120 corresponding to it, and a stop block 150 is arranged on the male terminal 120. The stop block 150 is arranged one-to-one with the support block 130, and the stop block 150 abuts against the support block 130 corresponding to it. The stop block 150 is located on the side of the support block 130 corresponding to it away from the female end in the first direction.

[0045] Specifically, the stopper 150 is a magnetic block, and the stopper 150 can be attracted to the supporting block 130 .

[0046] In this embodiment, by setting the stopper 150, when the tail end of the support block 130 slides along the first sliding section 231, the stopper 150 will limit the support block 130 from rotating around the second direction, that is, see the attached Figure 4 As shown, the stopper 150 limits the support block 130 from rotating clockwise around the second direction.

[0047] When the connector is unplugged, the male connector 100 moves along the first direction away from the female connector 200. At this time, the tail end of the support block 130 will first pass through the connecting section 235 of the third sliding section 233. When the tail end of the support block 130 contacts the transition section 234 of the third sliding section 233 again, the support block 130 will rotate around the second direction under the promotion of the transition section 234, that is, see the attached Figure 4 As shown, the support block 130 can rotate counterclockwise around the second direction. During the rotation, the support block 130 will be attracted by the stopper 150, and then in the process that the tail end of the support block 130 moves in the opposite direction along the transition section 234 to the second sliding section 232 and the first sliding section 231, the tail end of the support block 130 will be used to clean and remove the dust on the transition section 234, the second sliding section 232 and the first sliding section 231 in turn.

[0048] Alternatively, in another possible embodiment, the head end of the support block 130 is rotatably mounted on the male terminal 120 via a torsion spring.

[0049] When the torsion spring is used to connect the head end of the support block 130 to the male terminal 120, similarly, during the sliding process of the tail end of the support block 130 along the first sliding section 231, the stopper 150 will limit the support block 130 from rotating around the second direction under force, that is, see the attached Figure 4 As shown, the stopper 150 limits the support block 130 from rotating clockwise around the second direction.

[0050] When the connector is pulled out, when the rear end of the support block 130 contacts the transition section 234 of the third sliding section 233 again, the support block 130 will rotate around the second direction under the promotion of the transition section 234, that is, see the attached Figure 4As shown, the support block 130 can rotate counterclockwise around the second direction. At this time, the torsion spring accumulates force to give the support block 130 a force to rotate in the opposite direction and reset. This force can make the tail end of the support block 130 close to the transition section 234, the second sliding section 232 and the first sliding section 231 during the reverse movement, and then the tail end of the support block 130 can be used to clean and remove the dust on the transition section 234, the second sliding section 232 and the first sliding section 231 in turn.

[0051] In this embodiment, both ends of the first housing 110 along the third direction are provided with card connecting pieces 115, and both ends of the second housing 210 along the third direction are provided with card interfaces 215, and the card connecting pieces 115 are provided in a one-to-one correspondence with the card interfaces 215. After the male connector 100 moves toward the female connector 200 along the first direction and is plugged into the female connector 200, the card connecting pieces 115 can be plugged into the card interfaces 215 provided correspondingly thereto.

[0052] By engaging the engaging piece 115 with the corresponding engaging interface 215 , the connection strength between the male connector 100 and the female connector 200 is improved, and the connector is prevented from being loosened.

[0053] In combination with the above embodiments, the specific working process is as follows:

[0054] When the male connector 100 and the female connector 200 are plugged together, the rear end of the support block 130 will contact the first sliding section 231 and move from the first end to the second end on the first sliding section 231. At this time, there is a gap between the male terminal 120 and the transition surface 216 in the third direction, and the stopper 150 will limit the support block 130 from rotating in the second direction. Figure 4 As shown, the stopper 150 limits the support block 130 from rotating clockwise around the second direction.

[0055] When the rear end of the support block 130 slides to the second sliding section 232, since the vertical distance from the contact point 121 to the rear end of the support block 130 along the third direction is greater than the vertical distance from the contact point 121 to the female terminal 220 along the third direction, the contact point 121 does not contact the female terminal 220 at this time, that is, there is a gap between the female terminal 220 and the male terminal 120 in the third direction, and the support block 130 will move the male terminal 120 in the first housing 110 in a compressed state. At this time, it is in the first stroke of insertion. The supporting member is in contact with the corresponding limiting slide 230, and the female terminal 220 is not in contact with the male terminal 120, that is, the male terminal 120 is supported by the supporting member, and the supporting member is used to slide instead of the male terminal 120, so that the direct friction between the male terminal 120 and the female terminal 220 is transferred to between the supporting member and the limiting slide 230, so as to avoid the male terminal 120 and the female terminal 220 always being in direct contact during the plugging process, thereby reducing the wear between the male terminal 120 and the female terminal 220 and extending the service life of the male terminal 120 and the female terminal 220.

[0056] After the tail end of the support block 130 slides along the second sliding section 232 to the transition section 234 of the third sliding section 233, the tail end of the support block 130 will move along the transition section 234 in the third direction to the side away from the inner wall of the second housing 210, and the male terminal 120 is gradually released. Since the vertical distance from the contact point 121 to the tail end of the support block 130 along the third direction is less than the vertical distance from the third end to the fourth end of the transition section 234, the contact point 121 on the male terminal 120 will first contact the female terminal 220, and then the contact point 121 on the male terminal 120 will continue to slide along the female terminal 220, leaving a gap between the tail end of the support block 130 and the connecting section 235 in the third direction. That is, the tail end of the support block 130 is in a suspended state. At this time, it is in the second stroke of insertion.

[0057] After that, the contact point 121 on the male terminal 120 will continue to slide along the female terminal 220, and the first plug block 240 will abut against the first pressure block 113, and the second plug block 140 will abut against the second pressure block 213. When the first plug block 240 abuts against the first pressure block 113, and the second plug block 140 abuts against the second pressure block 213, as the male connector 100 continues to approach the female connector 200, the first pressure block 113 will slide along the first direction in the first recoil cavity 111, squeeze out the air in the first recoil cavity 111, and then clean the space where the female terminal 220 is located, so that some dust is blown out. At the same time, the second pressure block 213 will slide along the first direction in the second recoil cavity 211, squeeze out the air in the second recoil cavity 211, and then clean the space where the male terminal 120 is located, so that some dust is blown out. By cleaning the space where the male terminal 120 and the female terminal 220 are located, the interference of dust on the electrical connection is reduced, and the stability of the connection is improved.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
