Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1, the utility model provides a power adapter's nested skeleton, it carries out spacing fixed to last position of inserting the chip through inserted sheet complementary unit 4, makes its condition that the skew dislocation can not appear in position when inserting for can not scratch the adjacent chip of inserting easily when inserting of last lock pin piece.

Including skeleton main part 1, set up inserted hole 2 on skeleton main part 1 and install the metal contact pin 3 at 1 tip of skeleton main part a plurality of auxiliary part groove 101 has been seted up to the one end of inserted hole 2 be equipped with inserted sheet complementary unit 4 in the auxiliary part groove 101, mounting groove 102 has been seted up in one side that is close to metal contact pin 3 to inserted hole 2 install spacer 5 in the mounting groove 102.

When the framework is produced, the inserting core piece can be inserted into the inserting hole 2, and due to the existence of the separating sleeve 5, the position of the inserting core piece after being inserted cannot be inclined, so that when a user subsequently inserts the inserting chip, the position of each inserting chip does not need to be adjusted by spending time, meanwhile, when the last inserting core piece is inserted, the inserting piece auxiliary mechanism 4 can play a role in guiding and limiting, the adjacent inserting chip cannot be scratched due to deviation and dislocation, and the protection performance is higher.

Specifically, as shown in fig. 1 and fig. 2, the insert sheet auxiliary mechanism 4 includes auxiliary guide bars 401 located in the auxiliary groove 101 and rotatably connected to the frame body 1, the number of the auxiliary guide bars 401 is the same as that of the auxiliary groove 101, and both of the auxiliary guide bars 401 and the auxiliary groove 101 may preferably be four, and the four auxiliary guide bars 401 are respectively and symmetrically disposed on two sides of the insertion opening 2, and the length of the auxiliary guide bar 401 is greater than the height of the auxiliary groove 101, so that the auxiliary guide bars 401 cannot move freely, the auxiliary guide bars 401 are connected to a clamping frame 402 having a u-shaped structure on one side far away from the separating sleeve 5, the clamping frame 402 can clamp the auxiliary guide bars 401 on two sides of the insertion opening 2, so that the auxiliary guide bars are parallel to the clamping frame 402, and two guide bars 403 are symmetrically disposed on the inner surface of the clamping frame 402.

The insertion sheet auxiliary mechanism 4 can realize guiding limit of an inserted chip, during actual operation, the clamping frame 402 can be directly pushed, so that the clamping frame 402 clamps the auxiliary guide strips 401 at two sides of the insertion port 2, when the insertion sheet is inserted, because the auxiliary guide strips 401 are in an L-shaped structure, and the thickness of the auxiliary guide strips 401 decreases linearly from the separating sleeve 5 to the clamping frame 402, when the clamping frame 402 clamps the auxiliary guide strips 401, the clamping frame 402 cannot be easily pulled out, and when the last insertion sheet is inserted, once the last insertion sheet contacts the auxiliary guide strips 401, the last insertion sheet slides along the inclined surfaces of the auxiliary guide strips 401 to be attached to the guide strips 403, and because the cross section of the guide strips 403 is in an isosceles trapezoid structure, when the insertion sheet contacts the auxiliary guide strips 401 and the insertion sheet guide strips 403 at the same time, the insertion sheet can only be parallel to the clamping frame 402 and inserted into the insertion port 2 (even if the insertion sheet is inserted into the insertion port 2 and deviates, the offset direction of the inserted chip can also face to the auxiliary guide bar 401, so that the adjacent inserting core pieces are not affected), and the condition that the adjacent inserting core pieces are scratched is avoided.

Furthermore, a plurality of partition blocks 501 with cross sections in an isosceles trapezoid structure are arranged on the inner wall of the partition sleeve 5 at equal intervals, the partition blocks 501 at the two ends of the partition sleeve 5 are respectively in one-to-one correspondence with the two guide strips 403, when the plug-in chip is inserted into the insertion opening 2, the position can be fixed through the plurality of partition blocks 501 (namely, the plug core piece can be clamped by the partition blocks 501, the manufacturing material of the plug core piece can be selected from insulating materials such as rubber blocks), and then the inserted plug core piece can be tightly attached to each other without dislocation, so that subsequent plug core piece installation is not affected.

As shown in fig. 1, a plurality of hollow heat conducting columns 404 penetrating through the framework main body 1 are arranged at one end of the auxiliary conducting bar 401 close to the separation sleeve 5, an arc-shaped groove 405 is formed at one end of the hollow heat conducting column 404 far away from the auxiliary conducting bar 401, the hollow heat conducting columns 404 are arranged to rapidly dissipate heat in the framework after components such as a ferrule sheet are mounted, and the arc-shaped groove 405 is arranged to enable the auxiliary coil to be wound more conveniently without being greatly influenced.
