下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
第一实施例：First embodiment:
如图1所示，为本发明的第一实施例中安规陶瓷Y电容的示意图，该安规陶瓷Y电容包括：As shown in Figure 1, it is a schematic diagram of a safety ceramic Y capacitor in the first embodiment of the present invention, and the safety ceramic Y capacitor includes:
陶瓷片1，包括相对的第一板面11和第二板面12；Ceramic sheet 1, comprising opposite first plate surface 11 and second plate surface 12;
相互分离设置的两个第一电极2，设置于第一板面11上；Two first electrodes 2 arranged separately from each other are arranged on the first plate surface 11;
至少一个第二电极3，设置于第二板面12上；At least one second electrode 3 is arranged on the second plate surface 12;
其中两个第一电极2和至少一个第二电极3构成至少两个串联的电容。Wherein two first electrodes 2 and at least one second electrode 3 form at least two capacitors connected in series.
这样，由于设置于陶瓷片1第一板面11上的两个第一电极2相互分离设置，且至少一个第二电极3设置于与第一板面相对的第二板面12上，因此两个第一电极2和至少一个第二电极3能够构成至少两个串联的电容，从而使得至少两个串联的电容能够集成在一个陶瓷片上并封装为一个成品的安规陶瓷Y电容，解决了现有技术中在充电器中充电电路的初级电路部分和次级电路部分之间放置两个安规Y1电容或者两个安规Y2电容时，充电电路占用空间较大从而导致充电器体积较大的问题，提高了安规陶瓷Y电容的利用率，并且提高了充电器产品的安全性，减小了充电器产品的体积。In this way, since the two first electrodes 2 arranged on the first plate surface 11 of the ceramic sheet 1 are separated from each other, and at least one second electrode 3 is arranged on the second plate surface 12 opposite to the first plate surface, both A first electrode 2 and at least one second electrode 3 can form at least two capacitors in series, so that at least two capacitors in series can be integrated on a ceramic chip and packaged as a finished safety ceramic Y capacitor, which solves the current problem In the prior art, when two safety Y1 capacitors or two safety Y2 capacitors are placed between the primary circuit part and the secondary circuit part of the charging circuit in the charger, the charging circuit takes up a lot of space, resulting in a larger charger. The problem is to improve the utilization rate of safety ceramic Y capacitors, improve the safety of charger products, and reduce the volume of charger products.
此外，进一步地，为了提高两个第一电极之间的绝缘耐压水平，相互分离的两个第一电极2之间的距离可以为2mm～7mm。此外，进一步地，为了在提高两个第一电极之间的绝缘耐压水平的同时，缩小两个第一电极之间的间距，从而最大程度的减小安规陶瓷Y电容的体积，相互分离的两个第一电极2之间可以设置有第一开槽。具体的，该第一开槽的宽度可以为0.3～5mm，且第一开槽的深度为可以为陶瓷片1的厚度的0.25～0.75倍。这样，可以在保证两个第一电极之间的绝缘耐压水平的同时，最大程度的缩小两个第一电极之间的间距。此外，在设置第一开槽后，可以在第一开槽内填充上涂层材料(例如环氧树脂)，这样由于涂层的绝缘耐压强度高于陶瓷片的绝缘耐压强度，可以提高两个第一电极之间的绝缘耐压水平。In addition, further, in order to improve the insulation withstand voltage level between the two first electrodes, the distance between the two separated first electrodes 2 may be 2mm˜7mm. In addition, further, in order to increase the insulation withstand voltage level between the two first electrodes and at the same time reduce the distance between the two first electrodes, thereby reducing the volume of the safety ceramic Y capacitors to the greatest extent, separate them from each other A first slot may be provided between the two first electrodes 2 . Specifically, the width of the first groove may be 0.3-5 mm, and the depth of the first groove may be 0.25-0.75 times the thickness of the ceramic sheet 1 . In this way, the distance between the two first electrodes can be minimized while ensuring the insulation withstand voltage level between the two first electrodes. In addition, after the first slot is set, the upper coating material (such as epoxy resin) can be filled in the first slot, so that since the dielectric withstand voltage strength of the coating is higher than that of the ceramic sheet, it can improve The insulation withstand voltage level between the two first electrodes.
另外，进一步地，继续参见图1，第二电极3的数量为一个时，第二电极3在第一板面11上的投影覆盖两个第一电极2，且第二电极3的第一边缘31在第一板面11上的投影与其中一第一电极2的边缘重合，第二电极3上与第一边缘31相对的第二边缘32在第一板面11上的投影与另一第一电极2的边缘重合。这样，可以保证两个第一电极2与一个第二电极3之间能够构成两个串联的安规Y电容。In addition, further, continuing to refer to FIG. 1, when the number of the second electrode 3 is one, the projection of the second electrode 3 on the first plate surface 11 covers two first electrodes 2, and the first edge of the second electrode 3 The projection of 31 on the first plate surface 11 coincides with the edge of one of the first electrodes 2, and the projection of the second edge 32 on the second electrode 3 opposite to the first edge 31 on the first plate surface 11 coincides with the edge of the other first electrode 3. The edges of one electrode 2 coincide. In this way, it can be ensured that two series-connected safety Y capacitors can be formed between two first electrodes 2 and one second electrode 3 .
另外，进一步地，继续参见图1，安规陶瓷Y电容还包括第一引脚4和第二引脚5，第一引脚4设置于其中一第一电极2上，第二引脚5设置于另一第一电极2上。这样，在将陶瓷片第一板面上的两个第一电极2和第二板面上一个第二电极3通过涂层材料(例如环氧树脂)封装成由两个串联Y电容组成的安规陶瓷Y电容之后，可以通过第一引脚和第二引脚将安规陶瓷Y电容插接在电路中。In addition, further, referring to Fig. 1, the safety ceramic Y capacitor also includes a first pin 4 and a second pin 5, the first pin 4 is set on one of the first electrodes 2, and the second pin 5 is set on the other first electrode 2. In this way, two first electrodes 2 on the first plate of the ceramic sheet and a second electrode 3 on the second plate are packaged into an safety device consisting of two series Y capacitors by coating material (such as epoxy resin). After the standard ceramic Y capacitor, the safety ceramic Y capacitor can be plugged into the circuit through the first pin and the second pin.
这样，通过在陶瓷片上的第一板面上设置相互分离的两个第一电极，在与第一板面相对的第二板面上设置一个第二电极，使得两个第一电极和一个第二电极构成两个串联的电容，从而使得两个串联的电容能够集成在一个陶瓷片上并封装为一个成品的安规陶瓷Y电容，解决了现有技术中在充电器中充电电路的初级电路部分和次级电路部分之间放置两个安规Y1电容或者两个安规Y2电容时，充电电路占用空间较大从而导致充电器体积较大的问题，提高了安规陶瓷Y电容的利用率，并且提高了充电器产品的安全性，减小了充电器产品的体积。In this way, two first electrodes separated from each other are arranged on the first plate surface on the ceramic sheet, and a second electrode is arranged on the second plate surface opposite to the first plate surface, so that the two first electrodes and one first electrode The two electrodes form two capacitors in series, so that the two capacitors in series can be integrated on a ceramic chip and packaged as a finished safety ceramic Y capacitor, which solves the problem of the primary circuit part of the charging circuit in the charger in the prior art When two safety Y1 capacitors or two safety Y2 capacitors are placed between the secondary circuit part, the charging circuit takes up a lot of space, resulting in a larger charger, which improves the utilization rate of the safety ceramic Y capacitors. Moreover, the safety of the charger product is improved, and the volume of the charger product is reduced.
第二实施例：Second embodiment:
如图2所示，为本发明的第二实施例中安规陶瓷Y电容的示意图。As shown in FIG. 2 , it is a schematic diagram of a safety ceramic Y capacitor in the second embodiment of the present invention.
在该实施例中，第二电极3为两个相互分离设置于第二板面12上的第二电极时，其中一第二电极3在第一板面11上的投影覆盖其中一第一电极2的整个电极和另一第一电极2的部分电极，另一第二电极3在第一板面11上的投影覆盖另一第一电极2上除部分电极之外的剩余部分电极，且其中一第二电极3的第一边缘31在第一板面11上的投影与其中一第一电极2的边缘重合，另一第二电极3上与第一边缘31相对的第三边缘33在第一板面11上的投影与另一第一电极2的边缘重合。In this embodiment, when the second electrodes 3 are two second electrodes separated from each other and arranged on the second plate surface 12, the projection of one of the second electrodes 3 on the first plate surface 11 covers one of the first electrodes. 2 and a partial electrode of the other first electrode 2, the projection of the other second electrode 3 on the first plate surface 11 covers the remaining partial electrodes on the other first electrode 2 except the partial electrodes, and wherein The projection of the first edge 31 of a second electrode 3 on the first plate surface 11 coincides with the edge of one of the first electrodes 2, and the third edge 33 opposite to the first edge 31 on the other second electrode 3 The projection on one plate surface 11 coincides with the edge of the other first electrode 2 .
这样，陶瓷片1的第一板面11上设置两个相互分离设置的两个第一电极2，与第一板面11相对的第二板面12上设置两个相互分离设置的两个第二电极3，且其中一第二电极3在第一板面11上的投影覆盖其中一第一电极2的整个电极和另一第一电极2的部分电极，另一第二电极3在第一板面11上的投影覆盖另一第一电极2上除部分电极之外的剩余部分电极，这样，可以保证其中一第二电极3与其中一第一电极2的整个电极和另一第一电极2的部分电极构成两个串联的电容，另一第二电极与另一第一电极上除部分电极之外的剩余部分电极组成的电容与两个已构成的串联电容相串联，从而构成三个串联的电容。依次类推，可以根据需要得到的串联电容的数量，调整第一电极和第二电极的数量和第二电极在第一板面上的投影区域，从而得到需求数量的串联电容。In this way, two first electrodes 2 separated from each other are arranged on the first plate surface 11 of the ceramic sheet 1, and two second electrodes 2 separated from each other are arranged on the second plate surface 12 opposite to the first plate surface 11. Two electrodes 3, and the projection of one of the second electrodes 3 on the first plate surface 11 covers the entire electrode of one of the first electrodes 2 and a part of the other first electrode 2, and the other second electrode 3 is on the first plate surface 11. The projection on the plate surface 11 covers the remaining part of the electrodes on the other first electrode 2 except for some electrodes, so that it can be ensured that one of the second electrodes 3 is connected with the whole electrode of one of the first electrodes 2 and the other first electrode. Part of the electrodes of 2 form two capacitors in series, and the capacitor composed of the other second electrode and the rest of the electrodes on the other first electrode except some electrodes is connected in series with the two formed capacitors in series, thus forming three capacitors. capacitors in series. By analogy, the number of first electrodes and second electrodes and the projected area of the second electrodes on the first board can be adjusted according to the number of series capacitors required, so as to obtain the required number of series capacitors.
此外，进一步地，相互分离的两个第二电极3之间的距离为2mm～7mm。这样，可以提高两个第二电极之间的绝缘耐压水平。另外，为了在提高两个第二电极之间的绝缘耐压水平的同时，缩小两个第二电极之间的间距，从而最大程度的减小安规陶瓷Y电容的体积，相互分离的两个第二电极3之间设置有第二开槽。具体的，第二开槽的宽度为0.3～5mm，且第二开槽的深度为陶瓷片1的厚度的0.25～0.75倍。这样，可以在保证两个第二电极之间的绝缘耐压水平的同时，最大程度的缩小两个第二电极之间的间距。此外，在设置第二开槽后，可以在第二开槽内填充上涂层材料(例如环氧树脂)，这样由于涂层的绝缘耐压强度高于陶瓷片的绝缘耐压强度，可以提高两个第二电极之间的绝缘耐压水平。In addition, further, the distance between the two separated second electrodes 3 is 2mm˜7mm. In this way, the insulation withstand voltage level between the two second electrodes can be improved. In addition, in order to reduce the distance between the two second electrodes while improving the insulation withstand voltage level between the two second electrodes, thereby reducing the volume of the safety ceramic Y capacitor to the greatest extent, the two separated from each other A second slot is arranged between the second electrodes 3 . Specifically, the width of the second groove is 0.3-5 mm, and the depth of the second groove is 0.25-0.75 times the thickness of the ceramic sheet 1 . In this way, the distance between the two second electrodes can be minimized while ensuring the insulation withstand voltage level between the two second electrodes. In addition, after the second slot is set, the upper coating material (such as epoxy resin) can be filled in the second slot, so that since the dielectric withstand voltage strength of the coating is higher than that of the ceramic sheet, it can improve The insulation withstand voltage level between the two second electrodes.
另外，进一步地，继续参见图2，安规陶瓷Y电容还包括第三引脚6和第四引脚7，第三引脚6设置于其中一第一电极2上，第四引脚7设置于其中一第二电极3上，其中设置有第四引脚7的第二电极3在第一板面11上的投影与设置有第三引脚6的第一电极2不重叠。这样，在将陶瓷片第一板面上的两个第一电极2和第二板面上两个第二电极3通过涂层材料(例如环氧树脂)封装成由三个串联Y电容组成的安规陶瓷Y电容之后，可以通过第三引脚和第四引脚将由三个串联Y电容组成的安规陶瓷Y电容插接在电路中。In addition, further, referring to Fig. 2, the safety ceramic Y capacitor also includes a third pin 6 and a fourth pin 7, the third pin 6 is set on one of the first electrodes 2, and the fourth pin 7 is set On one of the second electrodes 3 , the projection of the second electrode 3 with the fourth pin 7 on the first board surface 11 does not overlap with the first electrode 2 with the third pin 6 . In this way, the two first electrodes 2 on the first plate of the ceramic sheet and the two second electrodes 3 on the second plate are packaged by a coating material (such as epoxy resin) to be composed of three series Y capacitors. After the safety ceramic Y capacitor, the safety ceramic Y capacitor composed of three series Y capacitors can be plugged into the circuit through the third pin and the fourth pin.
这样，本实施例通过在陶瓷片上的第一板面上设置相互分离的两个第一电极，在与第一板面相对的第二板面上设置两个第二电极，使得两个第一电极和两个第二电极构成三个串联的电容，从而使得三个串联的电容能够集成在一个陶瓷片上并封装为一个成品的安规陶瓷Y电容，提高了安规陶瓷Y电容的利用率，并且使得当将由三个Y电容构成的安规陶瓷Y电容应用在电路中时，减小了电路的体积。In this way, in this embodiment, two first electrodes separated from each other are arranged on the first plate surface of the ceramic sheet, and two second electrodes are arranged on the second plate surface opposite to the first plate surface, so that the two first electrodes The electrode and the two second electrodes form three capacitors in series, so that the three capacitors in series can be integrated on one ceramic chip and packaged into a finished safety ceramic Y capacitor, which improves the utilization rate of the safety ceramic Y capacitor. Moreover, when the safety ceramic Y capacitor composed of three Y capacitors is applied in the circuit, the volume of the circuit is reduced.
第三实施例：Third embodiment:
本实施例提供了一种电子设备，该电子设备包括第一实施例和第二实施例中所示的安规陶瓷Y电容。这样，由于安规陶瓷Y电容上集成有至少两个串联的Y电容，因此减少了电子设备中电容的数量，从而减小了电子设备的体积。This embodiment provides an electronic device, which includes the safety ceramic Y capacitor shown in the first embodiment and the second embodiment. In this way, since at least two series-connected Y capacitors are integrated on the safety ceramic Y capacitor, the number of capacitors in the electronic device is reduced, thereby reducing the volume of the electronic device.
