Description

Technical Field

[0001] This utility model relates to the field of circuit connection technology, and specifically to a high-voltage connection component. Background Technology

[0002] Currently, the high-voltage working component inside vacuum electronic devices is usually connected to the inner electrode and the outer electrode by a flexible wire. The inner electrode is connected to the internal high-voltage working component, and the outer electrode is connected to the high-voltage power supply output terminal. The ends of the flexible wire connected to the inner electrode and the outer electrode are connected by spot welding or other methods. This high-voltage connection method has the following technical problems: (1) The connection between the two ends of the flexible wire is unreliable, and the risk of open circuit is high; (2) There is a risk that the flexible wire may come into contact with the metal end cap of the vacuum electronic device, which may cause a short circuit between the high-voltage working component and the end cap; (3) The connection between the flexible wire and the inner electrode and the connection between the flexible wire and the outer electrode are difficult and inconvenient to operate. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems in the prior art, such as the difficulty in connecting flexible wires, the high risk of open circuits, and the ease with which flexible wires can short-circuit upon contact with end caps. The following technical solution is provided:

[0004] A high-voltage connection assembly includes an inner electrode, an outer electrode, and a transition electrode. The inner electrode and the outer electrode are detachably inserted into both ends of the transition electrode. The end of the inner electrode that contacts the transition electrode and the end of the outer electrode that contacts the transition electrode are both arranged in a spiral shape.

[0005] The adapter electrode includes an insulating bushing, and the inner wall of the insulating bushing is provided with an adapter conductor; when the inner electrode and the outer electrode are respectively inserted into the two ends of the adapter electrode, one end of the adapter conductor contacts the inner electrode and the other end contacts the outer electrode.

[0006] The adapter conductor has symmetrical grooves at its top at both ends, and a positioning pin is located at the center of each groove. Preferably, the adapter conductor and the positioning pin are integrally formed.

[0007] The groove has a rounded corner on the inner side of its groove edge.

[0008] The insulating bushing is connected to the transition conductor by brazing or interference fit.

[0009] The insulating bushing is made of any one of alumina ceramic, zirconia ceramic, polyimide, and polyetheretherketone.

[0010] The material of the adapter conductor is oxygen-free copper or copper alloy.

[0011] A high-voltage connection assembly further includes a housing and an end cap, the housing being inserted into the end cap; an outer electrode is fixedly disposed on the end cap, an inner electrode is disposed inside the housing, and the outer electrode is connected to the inner electrode via an adapter electrode.

[0012] The upper part of the outer shell 4 is provided with a support plate, which is fixedly connected to the outer shell 4. The adapter electrode passes through the support plate and is fixedly mounted on the support plate.

[0013] This utility model has the following advantages:

[0014] (1) This utility model provides a high voltage connection component, which achieves reliable and fast connection between the inner electrode and the outer electrode by adding an adapter electrode.

[0015] (2) The end of the inner electrode that contacts the adapter electrode and the end of the outer electrode that contacts the adapter electrode are both designed in a spiral shape. This design ensures the reserved length of the wires at the connection end of the inner electrode and the connection end of the outer electrode, overcoming the limitation on the wire length requirements at the connection end of the inner electrode and the connection end of the outer electrode. At the same time, the spiral design gives the connection end of the inner electrode and the connection end of the outer electrode a certain degree of elasticity, so that even if some wires have poor contact during the connection process with the adapter electrode, the overall conductivity will not be affected, reducing the operational requirements of the connection process.

[0016] (3) The outer wall of the adapter electrode is provided with an insulating bushing, which avoids the risk of short circuit caused by the use of soft wires for connection in the prior art, which is easy to come into contact with the end cap.

[0017] (4) The two ends of the adapter conductor are grooved, which makes it very convenient for the inner electrode and the outer electrode to be inserted and contacted. Combined with the rounded corner design of the groove edge, it makes the insertion of the inner electrode and the outer electrode more convenient. At the same time, a positioning pin is provided inside the groove. The positioning pin plays a limiting role. Combined with the spiral design of the end of the inner electrode that contacts the adapter electrode and the end of the outer electrode that contacts the adapter electrode, the positioning pin is inserted into the middle space of the spiral structure of the inner electrode or the outer electrode. This design makes it more convenient to insert and connect the inner electrode, the outer electrode and the adapter electrode. No other positioning structure is needed. Assembly is very convenient and quick. At the same time, it ensures that the inner electrode and the outer electrode are not easy to detach from the adapter electrode.

[0018] (5) The high-voltage connection assembly provided by this utility model uses the adapter electrode to realize the fast and reliable connection between the high-voltage working part inside the vacuum device and the external electrode, which significantly reduces the risk of open circuit / short circuit, and the assembly operation is simple and easy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0028] See Figures 1 to 3A high-voltage connection assembly includes an inner electrode 1, an outer electrode 2, and a connecting electrode 3. The inner electrode 1 and the outer electrode 2 are detachably inserted into both ends of the connecting electrode 3. Both the end of the inner electrode 1 that contacts the connecting electrode 3 and the end of the outer electrode 2 that contacts the connecting electrode 3 are spirally arranged. The connecting electrode 3 connects the inner electrode 1 and the outer electrode 2. The spiral arrangement of both the inner electrode 1 (the end where it contacts the connecting electrode 3, which has a spiral design) and the outer electrode 2 (the end where it contacts the connecting electrode 3, which also has a spiral design) gives them a spring-like elasticity, while the spiral design also extends the length of the inner electrode 1 and the outer electrode 2. The spiral end of the inner electrode 1 and the spiral end of the outer electrode 2 are spirally designed. This allows them to be compressed during the insertion process when in contact with the adapter electrode 3, thus shortening the exposed conductor when the spiral end of the inner electrode 1 or the spiral end of the outer electrode 2 is inserted with the adapter electrode 3, preventing short circuits caused by contact between the outer electrode 2 and the end cap 5. At the same time, the spiral design extends the length of the inner electrode 1 and the outer electrode 2, ensuring the reserved length of the wires at the connection ends of the inner electrode 1 and the outer electrode 2, overcoming the limitations on the wire length requirements at the connection ends of the inner electrode 1 and the outer electrode 2.

[0029] The adapter electrode 3 includes an insulating bushing 31, and an adapter conductor 32 is provided on the inner wall of the insulating bushing 31. When the inner electrode 1 and the outer electrode 2 are respectively inserted into the two ends of the adapter electrode 3, one end of the adapter conductor 32 contacts the inner electrode 1, and the other end contacts the outer electrode 2. The design of the insulating bushing 31 effectively avoids contact between the outer electrode 2 and the end cap 5, thus preventing short circuits.

[0030] The top of both ends of the adapter conductor 32 is provided with symmetrical grooves 321, and a positioning pin 322 is provided at the center of the groove 321. Preferably, the adapter conductor 32 and the positioning pin 322 are integrally formed. The top of both ends of the adapter conductor 32 is designed with grooves 321. When the helical end of the inner electrode 1 or the helical end of the outer electrode 2 is inserted into the groove 321 of the adapter conductor 32, the helical design of the helical end of the inner electrode 1 or the outer electrode 2 causes it to be compressed like a spring within the groove 321 of the adapter conductor 32, so that the helical end of the inner electrode 1 or the helical end of the outer electrode 2 is positioned within the groove 321, preventing the inner electrode 1 or the outer electrode 2 from contacting other conductive components and causing a short circuit. At the same time, since the positioning pin 322 is provided at the center of the groove 321, it is convenient for the helical end of the inner electrode 1 or the helical end of the outer electrode 2 to be positioned and inserted into the groove 321. The positioning pin 322 is located in the space formed by the helical design in the middle of the helical end of the inner electrode 1 or the outer electrode 2.

[0031] The inner edge of each groove 321 is rounded. The rounded corner design facilitates the insertion of the inner electrode 1 or the outer electrode 2 into the adapter conductor 32.

[0032] The insulating bushing 31 and the transition conductor 32 are connected by brazing or interference fit. Both of these connection methods are simple and convenient to operate in actual production and operation.

[0033] The insulating bushing 31 is made of any one of alumina ceramic, zirconia ceramic, polyimide, and polyetheretherketone.

[0034] The material of the adapter conductor 32 is oxygen-free copper or copper alloy.

[0035] A high-voltage connection assembly further includes a housing 4 and an end cap 5, wherein the housing 4 is inserted into the end cap 5; an outer electrode 2 is fixedly disposed on the end cap 5, and an inner electrode 1 is disposed inside the housing 4; the outer electrode 2 is connected to the inner electrode 1 via an adapter electrode 3. The end cap 5 is generally a metal end cap 5, and the housing 4 is generally cylindrical in design, with the end cap 5 adapted to the insulating housing 4.

[0036] The upper part of the outer casing 4 is provided with a support plate 6, which is fixedly connected to the outer casing 4. The adapter electrode 3 passes through the support plate 6 and is fixedly mounted on the support plate 6. The support plate 6 is used to fix the adapter electrode 3.

[0037] The housing 4 has a high-voltage working component inside, which is connected to one end of the inner electrode 1.

[0038] The working principle of this utility model is as follows:

[0039] A support plate 6 is placed on top of the outer casing 4. Since a transfer electrode 3 is fixedly connected to the support plate 6, passing through it, one end of the inner electrode 1 is inserted into the transfer electrode 3, and the other end is connected to a high-voltage working component. During the insertion of the inner electrode 1 into the transfer electrode 3, the spiral end of the inner electrode 1 is inserted into the groove 321 of the transfer conductor 32, compressing the inner electrode 1. Excess wire length of the inner electrode 1 is compressed into the groove 321, preventing contact with other components and thus avoiding short circuits. Simultaneously, the rounded corner design of the groove 321 facilitates the insertion of the inner electrode 1. Furthermore, the positioning pin 322 designed within the groove 321 allows for easy insertion into the central space formed by the spiral design of the inner electrode 1, facilitating positioning. During the insertion of the external electrode 2 into the adapter electrode 3, the spiral end of the external electrode 2 is inserted into the groove 321 of the adapter conductor 32, compressing the external electrode 2. Excess wire length of the external electrode 2 is compressed into the groove 321, preventing short circuits caused by contact with the end cap 5. Simultaneously, the rounded corner design of the groove 321 facilitates the insertion of the external electrode 2. The positioning pin 322 within the groove 321 allows for easy insertion into the central space formed by the spiral design of the external electrode 2, facilitating positioning. Since the adapter conductor 32 is conductive, one end of the internal electrode 1 contacts the adapter electrode 3, and the other end of the adapter electrode 3 contacts the external electrode 2, thus achieving conductive connection between the internal electrode 1 and the external electrode 2.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
