Description

Technical Field

[0001] This utility model relates to charger technology, and more particularly to a charger assembly. Background Technology

[0002] Generally, chargers have an insulating shell and two metal contacts. To facilitate insertion of these contacts into sockets or power strips, most chargers currently have the contacts fixed to the insulating shell. When the charger is removed from the socket, the contacts are exposed, taking up space, resulting in an irregular shape and affecting aesthetics, as well as assembly efficiency. Therefore, existing chargers need to be improved to solve the problem of exposed metal contacts outside the insulating shell. Utility Model Content

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1 to 7 As shown, this charger assembly of the present invention includes a housing 1, a cover 2, a fixing base 3, and a power connection terminal 4. The remaining parts can be referred to in the prior art, so they will not be described in detail here.

[0016] The lower end of the housing 1 is provided with a cover 2, on which symmetrically arranged inserts 5 are provided. The inserts 5 are connected to each other by an insulating member 6, which is mounted on the cover 2 by a rotating shaft 7. Inside the housing 1, there is also a main board (not shown in the figure), on which two conductive posts 8 are provided with contact ports 10 that cooperate with the contact parts 9. The contact ports 10 are provided with a blocking surface 11 and a second contact slope 12.

[0017] The mounting base 3 is disposed inside the housing 1, and the mounting base 3 has symmetrically arranged mounting areas 13 in the middle. The mounting area 13 has a protrusion 14, an insertion groove 15, and a connecting groove 16. The protrusion 14 and the inner wall of the mounting area 13 form a limiting opening 17, and the connecting groove 16 connects the mounting area 13 and the insertion groove 15. The mounting base 3 has a through hole 18 in the middle, and a bolt 19 is disposed in the through hole 18, passing through the through hole 18 into the strip hole 20, and then connecting to the inner wall of the housing 1.

[0018] The conductive post 8 is placed in the insertion slot 15, and then the contact part 9 is pushed, so that the contact part 9 is pushed by force and keeps the contact part 9 moving downward. Then the conductive post 8 passes over the contact part 9, so that the upper end of the contact part 9 is inserted into the contact port 10, keeping the first contact slope 41 and the second contact slope 12 in contact.

[0019] The electrical terminal 4 is located in the installation area 13. The fixing base 3 restricts the electrical terminal 4 inside the housing 1 by bolts 19. The insert 5 is rotated to maintain the 90° rotation, so that the insert 5 and the electrical terminal 4 are electrically connected.

[0020] like Figure 1 As shown, the insert 5 does not rotate at this time, that is, the insert 5 is kept hidden. When charging is required, the insert 5 is bent to rotate 90°, keeping the insert 5 out of the hidden slot 22.

[0021] The lower end of the connecting groove 16 is provided with an extension 23, which is used to limit the position of the inclined part 24.

[0022] An avoidance ramp 25 is formed inside the installation area 13. The avoidance ramp 25 is used to maintain the movement of the installation section 26, so that under the push of the insert 5, the deformation section 27 is deformed by force, and then the installation section 26 is moved closer to the avoidance ramp 25.

[0023] The power terminal 4 consists of an elastic arm 28, a sliding arm 29, and a contact arm 30. The sliding arm 29 connects the elastic arm 28 and the contact arm 30. The sliding arm 29 has a slotted hole 20, into which a bolt 19 is inserted. Because of the slotted hole 20, the power terminal 4 can be displaced under the push of the insert 5, thus providing cushioning. That is, when the deformed section 27 can no longer be compressed, the entire power terminal 4 can remain movable, thereby allowing the inclined section to bear the force.

[0024] The elastic arm 28 consists of an installation section 26 and a deformation section 27. The installation section 26 is provided with an insertion part 31, a first arc-shaped part 32, and a pushing part 33. The insertion part 31 is inserted into the limiting port 17. The middle of the first arc-shaped part 32 forms a recessed groove 34 that mates with the protrusion 14. The pushing part 33 is provided with a stepped groove 35, which is used to limit the position of the insert 5, keeping the insert 5 in a restrained position. The insert 5 will only rotate when subjected to external force. The deformation section 27 consists of a first deformation part 36, a second deformation part 37, and a third deformation part 38. The third deformation part 38 is connected to the sliding arm 29 through a sliding part 39.

[0025] The contact arm 30 is composed of a second arc-shaped part 40, an inclined part 24 and a contact part 9, and the contact part 9 is provided with a first contact inclined surface 41.

[0026] When the insert 5 rotates, i.e., rotates in the F direction, the pushing part 33 is pushed, thereby keeping the deformation section 27 deformed by force, keeping the pushing part 33 in contact with the insert 5 under force, and achieving a stable electrical connection.

[0027] The insulating part 6 on the insert 5 is used to prevent electrical connection between the two inserts 5, thus insulating them and leaving both ends of the insert 5 exposed. The inserts 5 are connected by an insulating sleeve 21, which is integrally formed with the insulating part 6. The rotating shaft 7 is located in the middle of the insulating sleeve 21, allowing the inserts 5 and the insulating part 6 to rotate around the rotating shaft 7.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
