DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] The present invention provides an MTP connector, such as Figures 1 to 5 As shown, it includes a connecting plug 1 and an adapter housing 2, the plug core at the rear end of the connecting plug 1 is correspondingly inserted into the inner groove 3 of the adapter housing 2, both ends of the inner groove 3 are provided with a clamping rod 4 that limits the connecting plug 1, the inner side of the connecting plug 1 is provided with a through groove 5 corresponding to the clamping rod 4, both ends of the outer side of the adapter housing 2 are provided with a clamping groove, the outer side of the clamping groove is clamped with an elastic clamping frame 6, and both sides of the elastic clamping frame 6 are provided with springs 7, the inner side of the end surface of the spring 7 is provided with a chamfered surface 8, both sides of the connecting plug 1 are provided with a side frame 9, and the two side frames 9 are connected to the two springs 7 One corresponds to the other, and the inner side of the side frame 9 is provided with a locking component that limits the connection plug 1, the locking component includes a patch plate 10, the inner side of the side frame 9 is provided with a side groove corresponding to the locking component, and the patch plate 10 and the end of the spring piece 7 are both located inside the side groove, the rear side of the patch plate 10 is connected to the front side of the side groove by a plurality of first rubber strips 11, the elastic force of the plurality of first rubber strips 11 makes the front side of the patch plate 10 fit with the end face of the spring piece 7, the top and bottom of the patch plate 10 are provided with wedge blocks 12 for clamping the spring piece 7, and the front side of the wedge block 12 is fixed with a convex strip 13 for clamping the end of the spring piece 7. In the process of inserting the plug of the connection plug 1 into the adapter housing 2, the side frame 9 of the connection plug 1 gradually approaches the spring sheet 7 until the inner side of the side frame 9 contacts the outer side of the spring sheet 7. The connection plug 1 that moves backward uses the side frame 9 to squeeze the spring sheet 7. The spring sheet 7 approaches the side of the adapter housing 2 under the pressure. The moving side frame 9 slides on the surface of the spring sheet 7 using the adhesive plate 10. The adhesive plate 10 is pulled to separate from the spring sheet 7. The moving adhesive plate 10 cooperates to squeeze multiple first rubber strips 11. At this time, the elastic force of the spring sheet 7 makes the end of the spring sheet 7 move to the inside of the side groove of the side frame 9. The adhesive plate 10 is released. The elastic force of multiple first rubber strips 11 makes the front side of the adhesive plate 10 fit with the end face of the spring sheet 7. At this time, the wedges 12 at the top and bottom of the adhesive plate 10 cooperate with the end of the snap spring sheet 7 using the convex strips 13 to complete the locking of the connection plug 1. Another connection plug 1 is inserted into the other side opening of the adapter housing 2. At this time, the two connection plugs 1 are connected correspondingly using the adapter housing 2.

[0029] When the connecting plug 1 is pulled, the end of the spring sheet 7 cooperates with the limiting plate 10, and the moving connecting plug 1 squeezes the multiple first rubber strips 11 through the side frame 9 and the plate 10. At this time, the elastic force of the multiple first rubber strips 11 makes the wedge block 12 cooperate with the snap spring sheet 7 using the convex strip 13, thereby preventing the connecting plug 1 from being pulled out of the adapter housing 2 due to simple pulling, thereby ensuring the stability of the connection between the connecting plug 1 and the adapter housing 2.

[0030] exist Figure 5 and Figure 6 In the embodiment, a limiting rod 14 penetrating the side frame 9 is fixed to the rear side of the plate 10, and a circular plate is fixed to the rear end of the limiting rod 14. The elastic force of the first rubber strips 11 makes the front side of the circular plate fit with the rear side of the side frame 9, the top surface of the wedge block 12 fits with the inner top surface of the side groove, the bottom surface of the wedge block 12 fits with the inner bottom surface of the side groove, and the bottom surface of the wedge block 12 at the top and the top surface of the wedge block 12 at the bottom fit with the top surface and the bottom surface of the wedge block 12 respectively. When the limiting rod 14 is pulled by the circular plate to move, the moving limiting rod 14 drives the plate 10 to move synchronously. At this time, the plate 10 can be moved inside the side groove by pulling. At this time, the moving plate 10 cooperates with the pressure of the first rubber strips 11 in the process of moving away from the spring sheet 7.

[0031] The top and bottom ends of the sticking plate 10 are fixed with convex plates, and the side of the convex plate is fixed with a convex rod 101 that penetrates the wedge block 12. The surface of the convex rod 101 is sleeved with a first spring 15, one end of the first spring 15 is connected to the convex plate, and the other end of the first spring 15 is connected to the wedge block 12. The outer side surface of the plate 10 fits with the inner wall of the side groove to prevent the plate 10 from rotating during the movement. The plate 10 drives the two wedge blocks 12 to move synchronously during the movement. The plate 10 and the side groove cooperate to limit the wedge blocks 12 to prevent the wedge blocks 12 from rotating at the top and / or bottom of the plate 10, and the elastic force of the first spring 15 makes the outer side surface of the wedge blocks 12 fit with the inner wall of the side groove. At this time, the outer side surface of the plate 10 is flush with the outer side surface of the wedge blocks 12. The elastic force of the multiple first rubber strips 11 makes the front side surface of the plate 10 fit with the end surface of the spring piece 7. The two wedge blocks 12 both use the convex strips 13 to cooperate to limit the top and bottom ends of the spring piece 7 to ensure the connection stability between the connecting plug 1 and the adapter housing 2.

[0032] exist Figure 7 and Figure 8In the embodiment, a pressing component corresponding to the spring piece 7 is provided on the outer side of the side frame 9, and an outer groove corresponding to the pressing component is provided on the outer side of the side frame 9. The outer groove and the side groove are connected by a socket 17. The pressing component includes an outer cover 18. The side frame 9, the pressing component and the locking component are all made of insulating material. The outer cover 18 is made of silicone material. A pressing frame 19 is provided on the inner side of the outer cover 18. The inner end of the pressing frame 19 corresponds to the socket 17, and the diameter of the pressing frame 19 is smaller than the diameter of the socket 17. A pressure strip 20 is provided inside the pressure frame 19. The inner end of the pressure strip 20 corresponds to the outer side of the spring piece 7 through the socket 17. The outer side of the pressure frame 19 is fixedly connected to the inner wall of the outer cover 18 by a plurality of second rubber strips 21. The outer cover 18 is pressed, and the outer cover 18 made of silicone material is deformed under the action of pressure. The pressing pressure presses the frame 19 close to the socket 17 through the multiple second rubber strips 21, and the deformed outer cover 18 pushes the pressure strip 20 close to the socket 17. The inner end of the pressure frame 19 is inserted into the socket 17. The pressure applied to the outer cover 18 is released, and the elastic force of the outer cover 18 itself pulls the pressure strip 20 away from the socket 17, and the outer cover 18 uses the second rubber strips 21 to pull the pressure frame 19 away from the socket 17.

[0033] exist Figures 5 to 8 In the figure, a slope 121 is provided inside the front side surface of the wedge block 12, and the slope 121 is located on the inner side of the convex strip 13. The outer side of the convex strip 13 is provided with an arc surface 16 corresponding to the chamfered surface 8. The wedge block 12 cooperates with the end of the buckle spring piece 7 by using the convex strip 13 under the elastic force limitation of multiple first rubber strips 11. When the outer cover 18 is pressed so that the inner end of the pressure strip 20 contacts the outer side surface of the spring piece 7 through the socket 17, the pressure of the pressure strip 20 on the spring piece 7 makes the end of the spring piece 7 close to the outer side surface of the adapter housing 2. At this time, the end of the spring piece 7 moves, and the end of the spring piece 7 uses the chamfered surface 8 to push the convex strip 13 to move. The inwardly moved convex strip 13 drives the wedge block 12 to squeeze the first spring 15 on the surface of the convex rod 101. Since the spring piece 7 is fixedly connected to the elastic card frame 6, the moving end of the spring piece 7 slides on the outer side surface of the convex strip 13 using the chamfered surface 8, and the end of the spring piece 7 pushes the patch plate 10 to squeeze the first rubber strip 11 during the movement until the end of the spring piece 7 is separated from the convex strip 13. The elastic force of the first rubber strip 11 makes the patch plate 10 close to the spring piece 7, and the moving patch plate 10 makes the inclined surface 121 of the wedge block 12 contact the end of the spring piece 7.

[0034] When the connecting plug 1 is pulled, the connecting plug 1 pulls the side frame 9 to move, and the moving side frame 9 uses the inclined surface 121 of the wedge block 12 to slide on the end surface of the spring piece 7. At this time, the inclined surface 121 makes the end of the spring piece 7 move out from the inside of the side groove, and the sliding friction between the spring piece 7 and the inclined surface 121 makes the plate 10 squeeze the first rubber strip 11 until the outer side surface of the spring piece 7 fits with the inner side surface of the plate 10 of the side frame 9, and the connecting plug 1 is continued to be pulled. At this time, the side frame 9 of the connecting plug 1 is separated from the spring piece 7, and the core of the connecting plug 1 is pulled out from the inside of the adapter housing 2, thereby realizing the rapid separation of the connecting plug 1 and the adapter housing 2.

[0035] exist Figure 7 and Figure 8 In the embodiment, the pressing component includes two pressing plates 22, which are respectively located at the top and bottom of the inner side of the outer groove. A vertical rod 23 penetrating the two pressing plates 22 is provided inside the outer groove. A second spring 24 is sleeved on the surface of the vertical rod 23. The top end of the second spring 24 is connected to the bottom surface of the top pressing plate 22, and the bottom end of the second spring 24 is connected to the top surface of the bottom pressing plate 22. The second spring 24 is in a compressed state. The elastic force of the second spring 24 separates the two pressing plates 22 from each other until the top surface of the top pressing plate 22 fits with the inner top surface of the outer groove, and the bottom surface of the bottom pressing plate 22 fits with the inner bottom surface of the outer groove. The outer groove uses the vertical rod 23 to limit the two pressing plates 22, ensuring the horizontal effect of the pressing plates 22 inside the outer groove.

[0036] Baffles 25 are fixed to the top and bottom of the pressing frame 19. The two baffles 25 correspond to the two pressing plates 22 one by one. The baffles 25 and the pressing plates 22 are connected by a rotating frame 26. The distance between the inner ends of the two rotating frames 26 is smaller than the distance between the outer ends of the two rotating frames 26. The inner side of the baffle 25 does not overlap with the inner side of the pressing frame 19. The inner side of the pressing frame 19 is inserted into the socket 17 by pressing, and the inner side of the baffle 25 is in contact with the outer side of the outer groove. When the external component impacts the outer cover 18, causing the inner end of the pressure frame 19 to be inserted into the socket 17, the moving pressure frame 19 uses the baffle 25 to pull the inner end of the rotating frame 26 to move. The inner end of the rotating frame 26 is hinged to the baffle 25, and the outer end of the rotating frame 26 is hinged to the pressure plate 22. At this time, the rotating frame 26 rotates under the drive of the baffle 25, and the rotating rotating frame 26 pulls the pressure plate 22 to move. At this time, the two pressure plates 22 cooperate to squeeze the second spring 24, and the elastic force of the second spring 24 absorbs the impact force of the external component. At this time, the inner side surface of the impact baffle 25 is in contact with the outer side surface of the outer groove, and the elastic force of multiple second rubber strips 21 further absorbs the impact force of the external component, preventing the inner end of the pressure strip 20 from impacting the outer side surface of the spring piece 7, and avoiding the separation of the end of the spring piece 7 from the arc surface 16 of the convex strip 13 due to a simple collision.

[0037] Working principle of the present invention:

[0038] Reference Figures 1 to 8As shown, in the process of correspondingly inserting the insert of the connecting plug 1 into the inside of the adapter housing 2, the side frame 9 of the connecting plug 1 gradually approaches the spring sheet 7 until the inner side of the side frame 9 contacts the outer side of the spring sheet 7. The backward moving connecting plug 1 uses the side frame 9 to squeeze the spring sheet 7. The spring sheet 7 approaches the side of the adapter housing 2 under the action of pressure. The moving side frame 9 slides on the surface of the spring sheet 7 using the sticking plate 10. When the limiting rod 14 is pulled to move by the circular plate, the moving limiting rod 14 drives the sticking plate 10 to move synchronously. At this time, the sticking plate 10 can be moved inside the side groove by pulling.

[0039] The plate 10 is separated from the spring sheet 7 by pulling, and the moving plate 10 cooperates to squeeze the multiple first rubber strips 11. At this time, the elastic force of the spring sheet 7 makes the end of the spring sheet 7 move to the side groove of the side frame 9, and the plate 10 is released. The elastic force of the multiple first rubber strips 11 makes the front side of the plate 10 fit with the end face of the spring sheet 7. At this time, the wedges 12 at the top and bottom of the plate 10 use the convex strips 13 to cooperate with the end of the snap spring sheet 7 to complete the locking of the connecting plug 1. At this time, the connecting plug 1 is pulled. Since the end of the spring sheet 7 cooperates to limit the plate 10, the moving connecting plug 1 squeezes the multiple first rubber strips 11 through the side frame 9 and the plate 10. At this time, the elastic force of the multiple first rubber strips 11 makes the wedges 12 use the convex strips 13 to cooperate with the snap spring sheet 7 to avoid the connecting plug 1 from being pulled out of the adapter housing 2 due to simple pulling, thereby ensuring the stability of the connection between the connecting plug 1 and the adapter housing 2.

[0040] When the external component impacts the outer cover 18, causing the inner end of the pressure frame 19 to be inserted into the socket 17, the moving pressure frame 19 uses the baffle 25 to pull the inner end of the rotating frame 26 to move. The inner end of the rotating frame 26 is hinged to the baffle 25, and the outer end of the rotating frame 26 is hinged to the pressure plate 22. At this time, the rotating frame 26 rotates under the drive of the baffle 25, and the rotating rotating frame 26 pulls the pressure plate 22 to move. At this time, the two pressure plates 22 cooperate to squeeze the second spring 24, and the elastic force of the second spring 24 absorbs the impact force of the external component. At this time, the inner side surface of the impact baffle 25 is in contact with the outer side surface of the outer groove, and the elastic force of multiple second rubber strips 21 further absorbs the impact force of the external component, preventing the inner end of the pressure strip 20 from impacting the outer side surface of the spring piece 7, and avoiding the separation of the end of the spring piece 7 from the arc surface 16 of the convex strip 13 due to a simple collision.

[0041] When the outer cover 18 is pressed so that the inner end of the pressure strip 20 contacts the outer side surface of the spring piece 7 through the socket 17, the pressure of the pressure strip 20 on the spring piece 7 makes the end of the spring piece 7 close to the outer side surface of the adapter housing 2. At this time, the end of the spring piece 7 moves, and the end of the spring piece 7 uses the chamfered surface 8 to push the convex strip 13 to move. The inwardly moved convex strip 13 drives the wedge block 12 to squeeze the first spring 15 on the surface of the convex rod 101. Since the spring piece 7 is fixedly connected to the elastic card frame 6, the moving end of the spring piece 7 slides on the outer side surface of the convex strip 13 using the chamfered surface 8, and the end of the spring piece 7 pushes the patch plate 10 to squeeze the first rubber strip 11 during the movement until the end of the spring piece 7 is separated from the convex strip 13. The elastic force of the first rubber strip 11 makes the patch plate 10 close to the spring piece 7, and the moving patch plate 10 makes the inclined surface 121 of the wedge block 12 contact the end of the spring piece 7.

[0042] When the connecting plug 1 is pulled, the connecting plug 1 pulls the side frame 9 to move, and the moving side frame 9 uses the inclined surface 121 of the wedge block 12 to slide on the end surface of the spring piece 7. At this time, the inclined surface 121 makes the end of the spring piece 7 move out from the inside of the side groove, and the sliding friction between the spring piece 7 and the inclined surface 121 makes the plate 10 squeeze the first rubber strip 11 until the outer side surface of the spring piece 7 fits with the inner side surface of the plate 10 of the side frame 9, and the connecting plug 1 is continued to be pulled. At this time, the side frame 9 of the connecting plug 1 is separated from the spring piece 7, and the core of the connecting plug 1 is pulled out from the inside of the adapter housing 2, thereby realizing the rapid separation of the connecting plug 1 and the adapter housing 2.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
