DETAILED DESCRIPTION

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, the utility model provides two technical solutions:

[0026] The first embodiment: A power adapter that prevents interface breakage, including an adapter body 1, a connector limiter 2 and a wiring harness protection component.

[0027] An electrical slot is provided in the middle of one end of the adapter body 1, into which a connector is inserted, and limiting slots 11 are provided on both sides of one end of the adapter body 1;

[0028] The joint limiter 2 is arranged on both sides of one end of the adapter body 1, and the joint limiter 2 is connected to the limit slide 11 on the adapter body 1, and the two joint limiters 2 cooperate to limit the connector. The joint limiter 2 includes a movable plate 21, and a limit slider 22 is fixed to the inner middle part of the movable plate 21. The limit slider 22 is located in the limit slide 11, which plays a limiting role to prevent the movable plate 21 from separating from the adapter body 1, and at the same time plays a guiding role, so that the movable plate 21 keeps linear movement. One end of the limit slider 22 passes through The first spring 23 is connected to the inner wall of one end of the limiting slide groove 11. The setting of the first spring 23 enables the movable plate 21 to automatically reset. A card slot 24 is provided in the middle of the movable plate 21. The card slot 24 is adapted to the extension part of the connector. The card slots 24 on the two movable plates 21 can cooperate to limit the connector so that the connector is stably connected to the adapter body 1. A dovetail slide groove 25 is provided in the middle of the inner side of the other end of the movable plate 21. A fixing sleeve 26 is fixed to the outside of the other end of the movable plate 21, and a pressure rod 27 is inserted into the inside of the fixing sleeve 26.

[0029] The second embodiment is mainly different from the first embodiment in that: the wiring harness protection part 3 is arranged on the connector limit part 2, which is used to protect the power line on the connector to prevent the power line at the connector from breaking. The wiring harness protection part 3 includes a connecting plate 31, which is located on the inner side of the other end of the movable plate 21, and a dovetail slider 32 is fixed to one side of the movable plate 21. The dovetail slider 32 is located in the dovetail slot 25, which plays a limiting role, thereby improving the connection strength between the connecting plate 31 and the movable plate 21, and preventing the connecting plate 31 from separating from the movable plate 21. A groove 33 is provided in the middle of the dovetail slider 32, and a limiting column 34 is inserted into the inside of the groove 33. One end of the limiting column 34 is connected to the bottom of the groove 33 through a second spring 35, and the other end of the limiting column 34 is adapted to the limiting groove provided in the middle of the bottom of the dovetail slot 25. The limiting column 34 is in the first The second spring 35 can be automatically inserted into the limit groove under the action of the second spring, limiting the connecting plate 31 on the movable plate 21. The limit groove is connected to the fixing sleeve 26. The pressure rod 27 in the fixing sleeve 26 can squeeze the limit column 34, separating the limit column 34 from the limit groove, so that the connecting plate 31 can be quickly separated from the movable plate 21. A support plate 36 is fixed to the middle of the other side of the connecting plate 31. Both sides of one end of the support plate 36 are fixed to the connecting plate 31 by reinforcing plates 37. The setting of the reinforcing plate 37 improves the connection strength between the support plate 36 and the connecting plate 31. A protective plate 38 is fixed to the other end of the support plate 36. The protective plate 38 is set to an arc structure. A rubber layer 39 is bonded to one side of the protective plate 38. The two protective plates 38 cooperate to protect one end of the power cord at the connector. The setting of the rubber layer 39 increases friction and protects the power cord.

[0030] When in use, first move the two movable plates 21 outward, so that the first spring 23 is compressed, and then the connector is inserted into the electrical slot on the adapter body 1, and then the movable plate 21 is released. At this time, the movable plate 21 is reset under the action of the first spring 23, and the two movable plates 21 cooperate with the card slot 24 thereon to limit the connector, so that the connector is stably installed. When the power cord at the connector needs to be protected, the dovetail slider 32 on the connecting plate 31 is inserted into the dovetail slide groove 25 on the plate until the limiting post 34 corresponds to the limiting groove in the dovetail slide groove 25. At this time, the limiting post 34 is inserted into the limiting groove under the action of the second spring 35, limiting the dovetail slider 32 in the dovetail slide groove 25, and then limiting the connecting plate 31 on the movable plate 21. At this time, the protective plate 38 on the support plate 36 contacts the power cord through the rubber layer 39. The two protective plates 38 cooperate to protect the power cord and avoid the connection between the power cord and the connector from breaking, thereby improving the stability and safety performance of the device.
