Description

Technical Field

[0001] This utility model specifically relates to a flexible pin-type square ceramic core. Background Technology

[0002] The core component of a ceramic capacitor is typically composed of alternating layers of ceramic dielectric and internal electrodes. These layers are very thin. When a voltage is applied to the two electrodes of the ceramic capacitor core, an electric field is generated inside the ceramic dielectric. Due to the dielectric properties of ceramic materials, polarization charges are generated on the dielectric surface. The accumulation of these polarization charges forms capacitance. Ceramic capacitor cores are characterized by high stability, good high-frequency characteristics, and small size, and are widely used in consumer electronics, communication equipment, and other fields.

[0003] Traditional ceramic core connection methods typically involve passing pins through vias on a printed circuit board and then soldering them to the other side of the board. This method is suitable for applications requiring high mechanical strength or manual soldering repairs. However, in the assembly of certain large electronic devices, due to manufacturing tolerances of different components and the accumulation of errors during assembly, traditional rigid connection methods may not guarantee a perfect connection for each core. Furthermore, during use, internal vibrations can easily occur, and traditional connection methods may cause signal transmission interruptions, affecting the operation of the device.

[0004] Therefore, it is necessary to invent a flexible pin-type square ceramic core to solve the above problems. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a flexible pin-type square ceramic core that can achieve adaptive connection.

[0007] (II) Technical Solution

[0009] The square ceramic sheet has multiple pin grooves on one side of its top, and a connecting piece is provided on the top of the pin groove. The connecting piece is connected to the upper electrode, and a pin insertion assembly is provided inside the pin groove.

[0010] The pin assembly is disposed in the pin groove and extends out of the pin groove. It includes a fixing block, which is fixed to the bottom of the pin groove and its upper end is connected to the bottom of the connecting piece. An elastic block is connected to one side of the fixing block, and a pin block is connected to the top of the elastic block. The elastic block is placed in the pin groove.

[0016] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:

[0017] 1.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-3 The elastic pin-type square ceramic core shown includes a square ceramic sheet 1, a thin sheet electrode 2 and a thick sheet electrode 3 mounted on the top of the square ceramic sheet 1, a sealing glass film 4 between the thin sheet electrode 2 and the thick sheet electrode 3, and a square ceramic film 5 on the top of the thick sheet electrode 3.

[0027] Specifically, a plurality of pin grooves 11 are provided on one side of the top of the square ceramic sheet 1, a connecting piece 6 is provided on the top of the pin groove 11, the connecting piece 6 is connected to the upper electrode, and a pin insertion assembly 7 is provided inside the pin groove 11.

[0028] Reference Figure 3 The pin assembly 7 is disposed in the pin groove 11 and extends out of the pin groove 11. It includes a fixing block 71, which is fixed to the bottom of the pin groove 11 and its upper end is connected to the bottom of the connecting piece 6. An elastic block 72 is connected to one side of the fixing block 71, and a pin block 73 is connected to the top of the elastic block 72. The elastic block 72 is placed in the pin groove 11.

[0029] Specifically, the pin groove 11 has a semi-circular cross-section, and the fixing block 71 matches its shape. The elastic block 72 is located on the upper part of one side of the fixing block 71. The elastic block 72 has a wavy cross-section, and the pin insertion block 73 is connected to the tail end of the elastic block 72 and is located in the upper part of the pin groove 11.

[0030] In this embodiment, a thin electrode 2 and a thick electrode 3 are mounted on top of a square ceramic sheet 1. During installation, it is essential to ensure a tight connection and good electrical contact between the electrodes and the ceramic sheet 1. Then, a sealing glass film 4 is placed between the thin electrode 2 and the thick electrode 3. The receiving groove 41 of the sealing glass film 4 must accurately correspond to the thin electrode 2 and the thick electrode 3, serving to protect and fix the electrodes. Afterward, a square ceramic diaphragm 5 is mounted on top of the thick electrode 3, forming a basic ceramic core structure.

[0031] Specifically, multiple pin grooves 11 are machined on one side of the top of the square ceramic sheet 1, and the cross-section of the pin grooves 11 is semi-circular. A fixing block 71 of the pin assembly 7 is installed at the bottom of the pin groove 11, ensuring its shape matches the pin groove 11 and guaranteeing the stability of the fixing block 71 within the pin groove 11. Next, an elastic block 72 is connected to the upper part of one side of the fixing block 71. The elastic block 72 has a wavy cross-section, and a pin block 73 is connected to the tail end of the elastic block 72, positioning the pin block 73 in the upper half of the pin groove 11. Then, a connecting piece 6 is installed on the top of the pin groove 11. The connecting groove 61 on the connecting piece 6 partially covers the pin groove 11 and connects to the top of the fixing block 71, thereby connecting the pin assembly 7 to the connecting piece 6.

[0032] Reference Figure 2 Both the thin electrode 2 and the thick electrode 3 are provided with electrostatic shielding electrodes 8 to ensure that they can effectively shield against external electrostatic interference.

[0033] Specifically, the sealing glass film 4 has a receiving groove 41 inside that corresponds to the thin sheet electrode 2 and the thick sheet electrode 3, and the overall size of the sealing glass film 4 does not exceed the size of the square ceramic thick sheet 1 and the square ceramic film 5.

[0034] Specifically, the connecting piece 6 is provided with a connecting groove 61 corresponding to the pin groove 11. The connecting groove 61 partially covers the pin groove 11 and is connected to the top of the fixing block 71.

[0035] Specifically, the front end of the pin block 73 extends outside the pin groove 11, and its front cross-sectional area is smaller than its rear cross-sectional area.

[0036] In this embodiment, when the ceramic core is connected to an external device (such as a circuit board), the pin block 73 is aligned with the corresponding socket on the external device. Because the front cross-sectional area of ​​the pin block 73 is smaller than the rear cross-sectional area, the pin block 73 can be easily inserted into the socket. During insertion, the elastic block 72 elastically deforms according to the depth of the socket and the tightness of the connection. For example, if the socket is deep or a tighter connection is required, the elastic block 72 will be compressed, allowing the pin block 73 to be fully inserted and maintain good contact.

[0037] In this embodiment, during actual operation, when the ceramic core is in a complex electromagnetic environment, the electrostatic shielding electrode 8 can effectively block external electrostatic interference. For example, in the production workshop of electronic equipment, there may be a large number of static electricity sources, such as electrostatic generators and static electricity generated by friction. The ceramic core with the electrostatic shielding electrode 8 can ensure the normal operation of the internal electrodes and prevent signal abrupt changes or component damage caused by static electricity.

[0038] Specifically, the sealing glass film 4 effectively protects the thin electrode 2 and the thick electrode 3 during operation. During the transportation, installation, and use of the equipment, even slight impacts or vibrations can maintain the relative positions of the electrodes, thus preserving stable electrical performance. For example, when transporting electronic devices containing the ceramic core from one location to another, the sealing glass film 4 prevents displacement between the electrodes, ensuring stable signal transmission.

[0039] In this embodiment, when connected to external devices, the elastic deformation of the elastic block 72 allows the pin block 73 to adapt to different connection conditions. For example, on an automated production line, when a robotic arm inserts a ceramic core into a circuit board, the elastic pin assembly 7 can adapt to the possible errors in the robotic arm's operational precision. Even if the insertion angle or depth of the pin block 73 deviates slightly, the elastic block 72 can adjust through its own elastic deformation, ensuring a good electrical and mechanical connection between the pin block 73 and the socket.

[0040] Specifically, the connection between the connecting piece 6 and the pin groove 11, via the connecting groove 61 and the fixing block 71, ensures the stability of the connection during operation. Even under the influence of vibration, temperature changes, and other factors during long-term operation, this connection method is not prone to loosening. For example, in industrial control equipment, the equipment may operate continuously for extended periods and be exposed to vibration; this connection structure of the ceramic core ensures that the connection between the internal electrodes and the pin assembly 7 remains stable, thereby guaranteeing reliable signal transmission.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
