Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a charger with replaceable plug pins. Background Art

[0002] Existing chargers generally include a charger body and pins integrally formed on the charger body. Before there were power adapters with interchangeable pins, chargers all had fixed pins, but now the standards for power pins in many countries are different. Common ones include Chinese standards, American standards, European standards, Indian standards, Japanese standards, British standards, Korean standards, Australian standards, etc. Among them, the regular shapes of pins in different countries and regions are different. For example, my country generally uses two-pin plugs, while British plugs have three pins (two power pins and one ground pin). With modern people traveling more and more frequently, when charging electronic products such as mobile phones and tablets, they often face the situation that the pins of the charger are not compatible with the local sockets. For this reason, it is necessary to prepare two chargers or buy a new charger locally, which increases costs and is inconvenient to carry. In view of this, technicians in this field have designed a charger with replaceable plugs. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a charger with replaceable pins that is safe to use and suitable for sockets in different countries. The pin pieces on the charger body can be removed and replaced by using two independent actions at the same time, avoiding the risk of the charger body and the pin pieces being separated during use.

[0004] The technical solution of the utility model is: a charger with replaceable pins, comprising a charger body and a pin piece, the pin piece being detachably arranged on the charger body, the charger body being provided with an inwardly recessed assembly groove, the bottom wall of the assembly groove being provided with two groups of contact pins, the bottom wall of the assembly groove being provided with a button spring extending outward, a plurality of avoidance grooves being radially arranged on the inner side wall of the assembly groove, a locking protrusion being arranged at the top of the avoidance groove, the pin piece comprising a buckle mounting seat and at least two groups of pins fixed on the buckle mounting seat, the buckle mounting seat being adapted to the assembly groove, the buckle mounting seat being arranged facing the pins, the buckle mounting seat being provided with a contact groove corresponding to the contact pin, the outer side wall of the buckle mounting seat being provided with a plug-in groove, a buckle through groove being arranged on the side of the plug-in groove, and the buckle through groove being adapted to the locking protrusion.

[0005] It can be seen from the above scheme that after the snap-on seat is installed in the assembly groove, the locking protrusion is rotated and snap-fitted into the locking slot along the plug-in slot for limiting, thereby realizing the snap-on installation of the pin piece on the charger body, and the avoidance groove is used to avoid the outer wall of the snap-on seat after snapping, and the contact foot is extended into the contact groove to realize electrical conduction between the charger body and the pin piece. The utility model realizes installation by rotating the pin piece and screwing the locking protrusion into the locking slot. Through the two independent actions of pressing the button spring and rotating the pin piece, the pin piece can be disassembled and replaced on the charger body, which is convenient, practical, safe and reliable.

[0006] The fixed end of the button spring is connected to the bottom wall of the assembly slot, the movable end of the button spring extends out of the assembly slot, and there is a movable gap between the bottom of the button spring and the charger body. It can be seen that the button spring is used to connect to the bottom wall of the assembly slot, and when the movable end of the button spring is pressed, the bottom wall of the assembly slot and the button spring are pressed down, driving the contact foot on the bottom wall of the assembly slot to move down and out, and after pressing the button spring, the pin part is rotated.

[0007] A circuit board is disposed in the charger body, and the contact pin is electrically connected to the circuit board. It can be seen that the electrical connection between the contact pin and the circuit board is used to achieve circuit conversion and electrical conduction.

[0008] A conductive clip is provided inside the buckle mount corresponding to the contact slot. The conductive clip is open at one end and provided with a clip slot. Both sides of the open end of the clip slot are arranged in an outwardly expanding arc shape. The clip slot is adapted to the contact pin, and the length of the clip slot is less than the length of the contact slot. It can be seen that after the pin piece is installed on the charger body, the contact pin is inserted into the connection slot and contacts the conductive clip to achieve electrical conduction. The open end of the clip slot is arranged in an outwardly expanding arc shape to facilitate the livestock foot to smoothly enter the clip slot after being inserted into the contact slot, thereby reducing the wear rate caused by repeated plugging and unplugging of the contact pin. The clip slot is used to clamp the contact pin.

[0009] The charger body also includes a shell and a bottom shell buckled on the bottom of the shell, and a charging port is arranged on the outer side wall of the shell. It can be seen that the assembly groove is located on the upper end surface of the shell, and the charging port is used to realize power supply to the charger body.

[0010] The upper surface of the button is provided with a plurality of anti-skid convex strips, which can be seen from this that the anti-skid convex strips are used to prevent skidding when the button is pressed. BRIEF DESCRIPTION OF THE DRAWINGS

Slot 31, a locking protrusion 5 is provided at the top of the avoidance slot 31, the pin member 2 includes a buckle mounting seat 6 and at least two groups of pins 7 fixed on the buckle mounting seat 6, the buckle mounting seat 6 is adapted to the assembly slot 3, the buckle mounting seat 6 and the pins 7 are arranged opposite to each other, the buckle mounting seat 6 is provided with a contact slot 61 corresponding to the contact pin 4, an insertion slot 8 is provided on the outer side wall of the buckle mounting seat 6, a buckle slot 9 is provided on the side of the insertion slot 8, and the buckle slot 9 is adapted to the locking protrusion 5, the installation of the charger is achieved by placing the pin member 2 into the assembly slot 3 on the charger body 1 and then rotating the pin member 2, and the disassembly of the charger needs to be completed by two independent actions of pressing the pressing spring sheet and rotating the pin member 2.

[0019] In this embodiment, four groups of the plug-in slots 8 and the buckling slots 9 are arranged in a circular array on the inner side wall of the assembly slot 3, the width of the plug-in slots 8 is adapted to the locking protrusion 5, the plug-in slots 8 are radially extended from the top end surface of the buckling seat 6 on the side wall of the assembly slot 3, the width of the plug-in slots 8 and the buckling slots 9 at the connection point is adapted to the width of the locking protrusion 5, the depth of the plug-in slots 8 is less than the depth of the buckling slots 9, the three outer sides of the button spring 10 have gaps with the shell 13 on the charger body 1, and there is space for movement when the button spring 10 is pressed up and down.

[0020] The charger body 1 further includes a shell 13 and a bottom shell 14 buckled on the bottom of the shell 13. A charging port 15 is provided on the outer wall of the shell 13. A circuit board is provided in the charger body 1, and the contact pins 4 are electrically connected to the circuit board. In this embodiment, the contact pins 4 are protruding plugs, two groups of which are provided, and the contact pins 4 are made of copper.

[0021] A conductive clip 12 is provided inside the buckle mount 6 corresponding to the contact groove 61. The conductive clip 12 is open at one end and provided with a clip groove 121. Both sides of the open end of the clip groove 121 are arranged in an arc shape that expands outward. The clip groove 121 is adapted to the contact foot 4. The length of the clip groove 121 is less than the length of the contact groove 61.
