[0035] Embodiment 1

[0036] Please refer to Figures 1 to 5 , Embodiment 1 of this utility model is: A power bank, including a main body 1 and an electrical connector assembly 2. A main control board 3 and a storage battery (not shown in the figure) are electrically connected inside the main body 1. The main control board 3 is connected to a first conductive terminal 41; the electrical connector assembly 2 is detachably installed on the main body 1. The electrical connector assembly 2 has a second conductive terminal 42 electrically connected to the first conductive terminal 41. Briefly, the first conductive terminal 41 and / or the second conductive terminal 42 are structural parts such as metal conductive elastic sheets, Pogo pins, etc.

[0037] The electrical connector assembly 2 includes a base 21 and a connector head 22 provided on the base 21. The second conductive terminal 42 is electrically connected to the connector head 22. A plug-in slot 11 is provided on the main body 1. The inner surface of the plug-in slot 11 has an exposed hole for the first conductive terminal 41 to be exposed. The base 21 has a plug-in block 211 that cooperates with the plug-in slot 11. It is easy to understand that the contact area of the first conductive terminal 41 can either extend into the plug-in slot 11 through the exposed hole or be retracted into the exposed hole. At this time, after the electrical connector assembly 2 is connected to the main body 1, the contact area of the second conductive terminal 42 extends into the exposed hole and contacts and conducts with the first conductive terminal 41.

[0038] To prevent the electrical connector assembly 2 from accidentally detaching from the main body 1, optionally, a block 212 is provided on the base 21, and a slot 12 is provided on the main body 1 to engage with the block 212; and / or, a slot 12 is provided on the base 21, and a block 212 is provided on the main body 1 to engage with the block 212. In this embodiment, the block 212 is provided at the end of the base 21, and the slot 12 is provided on the stop surface of the plug-in slot 11 opposite to the insertion direction of the electrical connector assembly 2, and the stop surface of the plug-in slot 11 can limit the insertion depth of the electrical connector assembly 2 in the plug-in slot 11.

[0039] Optionally, the plug-in slot 11 is connected to two adjacent walls of the main body 1. To facilitate the user to disassemble the electrical connector assembly 2 installed on the main body 1, in this embodiment, the outer surface of the main body 1 is provided with a withdrawal groove 13 connected to the plug-in slot 11, and the user can press the electrical connector assembly 2 in the plug-in slot 11 at the withdrawal groove 13 to withdraw the electrical connector assembly 2 from the plug-in slot 11.

[0040] The joint part 22 is rotatably connected to the base 21, and the second conductive terminal 42 is provided on the base 21 or on the joint part 22. When the second conductive terminal 42 is provided on the base 21, the joint part 22 is indirectly connected to the first conductive terminal 41 through the second conductive terminal 42 on the base 21. When the second conductive terminal 42 is provided on the joint part 22, the second conductive terminal 42 is a partial structure of the joint part 22. At this time, it can be considered that the joint part 22 is in direct contact and conduction with the first conductive terminal 41.

[0041] In order to well protect the joint part 22 in the storage state, preferably, the base 21 has a receiving groove 213 for receiving the joint part 22 .

[0042] A limiting elastic piece 214 is provided on the base 21, and a limiting block 221 cooperating with the limiting elastic piece 214 is provided on the rotating shaft of the connector head 22. The limiting block 221 has at least two limiting surfaces for abutting against the limiting elastic piece 214, and the included angle formed between any two of the limiting surfaces is less than 180°. The limiting elastic piece 214 is in surface contact with the limiting surfaces of the limiting block 221. When different limiting surfaces of the limiting block 221 are in surface contact with the limiting elastic piece 214, the relative rotation angle between the connector head 22 and the base 21 can be maintained, and different limiting surfaces of the limiting block 221 correspond to different rotation angles of the connector head 22 relative to the base 21, so that the user can adjust the angle of the connector head 22 to meet the current actual use needs, which is convenient for the user to use and helps to enhance the user experience. In this embodiment, the limiting block 221 has two mutually perpendicular limiting surfaces. When one limiting surface is in surface contact with the limiting elastic piece 214, the connector head 22 is in a retracted state for the user to carry. When the other limiting surface is in surface contact with the limiting elastic piece 214, the connector head 22 is in an extended state for the user to charge the electronic device. When the connector head 22 switches between the retracted state and the extended state, it rotates 90°.

[0043] The number of the electrical connector assemblies 2 is multiple. Therefore, the user can replace the electrical connector assembly 2 that needs to be replaced by himself.

[0044] Preferably, at least two of the connector heads 22 of the electrical connector assemblies 2 are of different types. For example, Type-C type, Micro USB type, Lightning type, etc. In this way, the user can select and install the corresponding type of electrical connector assembly 2 in the plug slot 11 according to the type of the charging interface of the electronic device to be charged, which can improve the use flexibility of the power bank and help to improve the utilization rate of the power bank.

[0045] Optionally, a plurality of the plug slots 11 are provided on the main body 1, and the electrical connector assembly 2 can be installed in each of the plug slots 11.

[0046] At least two of the plug slots 11 are provided with the exposed holes, and the main control board 3 is connected with at least two groups of the first conductive terminals 41. The first conductive terminals 41 with a plurality of groups are arranged corresponding to the exposed holes of different plug slots 11. In other words, at least two plug slots 11 on the main body 1 can be used for electrically connecting with the electrical connector assembly 2. The user can select and use the electrical connector assembly 2 in different plug slots 11 according to the needs, so that the user can hold the power bank in a more comfortable posture.

[0047] It should be noted that in the actual product, it is not required that each of the plug-in slots 11 is correspondingly provided with the first conductive terminal 41. In fact, the plug-in slot 11 without the corresponding first conductive terminal 41 can be used as a placement slot for placing the electrical connector assembly 2 that is not temporarily enabled by the user. When the user needs to enable the electrical connector assembly 2 in the placement slot, it can be directly installed in the plug-in slot 11 corresponding to the first conductive terminal 41.

[0048] Optionally, a first signal detection terminal 43 is provided on the main control board 3, and the electrical connector assembly 2 has a second signal detection terminal 44 electrically connected to the first signal detection terminal 43. The second signal detection terminal 44 is electrically connected to the joint part 22. The first signal detection terminal 43 and the second signal detection terminal 44 constitute a signal transmission bridge between the joint part 22 and the main control board 3, so that the charging signal of the external electronic device can be detected, thereby improving the use safety of the power bank.

[0049] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
