Description

Technical Field

[0002] Dental equipment usually includes a main unit and a device to be charged. The device to be charged is electrically connected to the main unit and supplies power to the main unit. The device to be charged generally uses a battery, a dental handle with a removable battery, a dental handle with a non-removable battery, etc. After the device to be charged is used, it needs to be inserted into a charging station for charging. The charging station generally has a charging slot, in which a conductive electrode is provided. The conductive electrode has an electrode contact. After the device to be charged is inserted into the charging slot, the electrode contact of the charging station is pressed by the electrode of the device to be charged, so that the electrode of the device to be charged and the electrode contact of the charging station are kept in contact.

[0003] However, the electrode contacts of the charging seat have always been protruding in the charging slot. When the component to be charged in the charging slot needs to be rotated, the electrode contacts are likely to interfere with the component to be charged, hindering the rotation of the component to be charged. In addition, the contacts of the component to be charged of the charging seat are clamped between the component to be charged and the slot wall of the charging slot. The electrode contacts are squeezed on both sides by the component to be charged and the slot wall, and are likely to be deformed, resulting in poor contact between the component to be charged and the electrode contacts.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0042] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0045] Please refer to Figures 1 to 6As shown, the charging seat 100 of the present application includes a shell 1 and a conductive spring 2 electrically connected to the charging circuit. A charging slot 11 is provided on the top of the shell 1 for placing the charging terminal of the component to be charged (not shown in the figure). The charging slot 11 is a downwardly concave slot structure. The specific shape of the charging slot 11 is not limited. The shape of the charging slot 11 is adapted to the shape of the charging terminal of the component to be charged. When the charging terminal of the component to be charged is hemispherical, the charging slot 11 is a hemispherical slot structure. When the charging terminal of the component to be charged is cylindrical, the charging slot 11 is a cylindrical slot structure. Preferably, the charging slot 11 and the charging terminal of the component to be charged are both hemispherical structures, and the slot wall of the charging slot 11 can provide guiding and limiting functions for the component to be charged. The charging slot 11 is arranged on the top of the shell 1 to facilitate the component to be charged (not shown in the figure) to be inserted into the charging slot 11 from top to bottom. An opening 12 is provided on the wall of the charging slot 11, and a conductive spring 2 is fixed on the housing 1. The conductive spring 2 has a conductive contact 21, which passes through the opening 12 and then convexly disposed in the charging slot 11; when the conductive contact 21 is pressed, the conductive spring 2 is deformed so that the conductive contact 21 can leave the charging slot 11 and move into the opening 12. In this embodiment, the part to be charged can be a battery or a handle with a battery.

[0046] In this embodiment, the part to be charged has a part electrode to be charged (not shown in the figure), and the conductive spring 2 and its conductive contact 21 are used to electrically connect with the part electrode to be charged. After the part to be charged is inserted into the charging slot 11, the part electrode to be charged squeezes the conductive contact 21 to achieve close contact between the two. When it is necessary to adjust the position of the part to be charged in the charging slot 11 by rotating the part to be charged, first press the part to be charged in the charging slot 11, and the part electrode to be charged applies pressure to the conductive contact 21. When the conductive contact 21 is pressed, it leaves the charging slot 11 and returns to the opening 12. The conductive contact 21 will not block the rotation of the part to be charged, and the rotation of the part to be charged is smoother. In addition, when the conductive contact 21 is pressed, it leaves the charging slot 11 and returns to the opening 12. The conductive contact 21 will not be sandwiched between the part to be charged and the slot wall of the charging slot 11, which can prevent the part to be charged and the slot wall from squeezing the conductive contact 21 on both sides, effectively preventing the conductive contact 21 from deforming, and ensuring good contact between the part to be charged and the conductive contact 21.

The shapes and sizes of the first opening 121 and the second opening 122 are respectively adapted to the positive electrode contact 221 and the negative electrode contact 231, and the edge of the first opening 121 provides a limiting effect for the positive electrode contact 221, and the edge of the second opening 122 provides a limiting effect for the negative electrode contact 231. The edge of the first opening 121 and the edge of the second opening 122 prevent the positive electrode contact 221 and the negative electrode contact 231 from shifting when moving; the first opening 121 and the second opening 122 are arranged at intervals, which can prevent the positive electrode contact 221 and the negative electrode contact 231 from contacting each other and causing a short circuit when the component to be charged is charged, and can further improve the safety of charging the component to be charged.
