Description

Technical field of the invention

The present invention relates to a charger, and more particularly to a charger by which an electrical contact or an electrical connection can be improved or ensured.

State of the art

In educational institutions such as schools and language teaching centers, it is common to use electronic devices such as tablet computers, laptops or Chromebooks as educational material. Effective charging of a variety of electronic devices for a large number of people involves technical issues (such as not requiring too much space or being centralized) that need to be resolved. In this context, Dell Technologies Inc. has launched a compact charging cart that allows multiple (eg, up to 36) electronic devices to be charged simultaneously. In this compact wagon, several divider or docking kits, also equipped with separator plates and meeting the specifications of typical electronic equipment, are placed in a movable box. In this way, an electronic device between two adjacent partition plates can be used. The compact self-loading wagon is usually equipped with a suitable number of sockets or power strips with extension cords (also known as multiple sockets) so that the sockets and all electronic devices can be interconnected via multiple power cords (eg USB charging cables) to simultaneously power multiple electronic devices to load.

In the current compact loader wagon described above, however, there are still the following, an improvement-requiring places: Although one end of the power cord is usually plugged into a socket in advance, but the user still has to plug the other end of the power cord into an electronic device , The USB plugs and sockets (including Type C USB plugs) of ordinary USB charging cords are typically designed to be connected by complementary shapes. Some younger users (for example, elementary school children, and more likely preschoolers) may not properly perform the plug-in operation, which may result in poor cable contact and therefore may not charge the electronic device properly. Thus, as the above-mentioned defects can be eliminated, the technical difficulty to be overcome is that of the inventor of the present invention.

Object of the invention

In view of the above-described problems of the conventional compact wagon, it is the object of the present invention to provide a charger, by which an electrical contact or an electrical connection can be improved or ensured.

To achieve the above object, the present invention provides a charger having an improved contact effect, comprising: a dock base, the dock base having a platform and a side wall laterally connected to the platform, a first sloped surface formed on the top of the platform, wherein the first inclined surface is inclined from top to bottom toward the side wall from the side remote from the side wall, a second inclined surface being formed on the platform side of the side wall, the second inclined surface and the first inclined surface connected to each other; a plurality of spring contact plugs, all of the spring contact plugs being attached to the sidewall of the dock base, whereby the spring contact pins of the spring contact plugs are exposed and may protrude from the second inclined surface; a plurality of storage boxes for electronic devices, wherein all storage boxes for electronic devices are arranged on the dock base, wherein the position of a respective storage box for electronic devices is adapted respectively to the position of the corresponding spring contact plug.
