Description

Technical Field

[0001] This utility model relates to the field of diode technology, specifically a split-type axial diode. Background Technology

[0002] A diode is an electronic device made of semiconductor material. It has two electrodes: a positive terminal (anode) and a negative terminal (cathode). When a forward voltage is applied between the diode's electrodes, it conducts; when a reverse voltage is applied, it cuts off. The conduction and cutoff of a diode are analogous to the switching on and off of a switch. An axial diode is one type of diode.

[0003] Existing axial diodes are typically integrated structures. When the anode or cathode pins are damaged, the entire diode needs to be replaced, resulting in high maintenance and operating costs. Furthermore, the anode and cathode pins cannot be protected during transport, leading to easy friction and wear between the anode and cathode pins on multiple diodes during transport. Therefore, there is an urgent need for a split-type axial diode to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a split-type axial diode to solve the problem mentioned in the background art. Existing axial diodes are usually integrated structures. When the anode or cathode pin is damaged, the whole unit needs to be replaced, which results in high maintenance and usage costs. In addition, the anode and cathode pins cannot be protected during transportation, which leads to the problem that the anode and cathode pins on multiple diodes are prone to mutual friction and wear during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A split-type axial diode includes a housing with threaded holes at both the left and right ends. An anode pin and a cathode pin are threaded into the two threaded holes, respectively. An N-type germanium plate is disposed inside the housing. The right side of the N-type germanium plate is in contact with the left end of the cathode pin. A metal contact wire is disposed at the left end of the N-type germanium plate. One end of the anode pin is in contact with the metal contact wire. One side of the N-type germanium plate is connected to the inner sidewall of the housing. A first sleeve and a second sleeve are respectively fitted onto one end of the anode pin and the cathode pin.

[0007] As a preferred embodiment of this utility model, both the first sleeve and the second sleeve are made of rubber.

[0008] As a preferred embodiment of this utility model, one end of both the anode pin and the cathode pin is provided with an external thread in the circumferential direction.

[0009] As a preferred embodiment of this utility model, one end of the first sleeve and the second sleeve respectively abuts against the left and right end faces of the outer shell.

[0010] As a preferred embodiment of the present invention, one end of the first sleeve and the second sleeve are both open and the other end is closed.

[0011] As a preferred embodiment of this invention, both the anode pin and the cathode pin are cylindrical in shape.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model has threaded holes at both the left and right ends of the outer casing, and external threads in the circumferential direction at one end of the anode and cathode pins. The anode and cathode pins are connected to the outer casing by threads, which allows for disassembly. When the anode or cathode pin is damaged, there is no need to replace the whole unit. Only the corresponding damaged anode or cathode pin needs to be replaced, which saves on later maintenance and usage costs.

[0014] 2. This utility model provides a first sleeve and a second sleeve at one end of the anode pin and the cathode pin respectively. The first sleeve and the second sleeve separate and protect the anode pin and the cathode pin during transportation, thereby preventing the anode pin and the cathode pin on multiple diodes from rubbing and wearing against each other during transportation.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0021] Please see Figure 1-3 A split-type axial diode includes a housing 1. Threaded holes are provided at both the left and right ends of the housing 1. An anode pin 5 and a cathode pin 4 are threaded into the two threaded holes, respectively. An N-type germanium plate 2 is disposed inside the housing 1. The right side of the N-type germanium plate 2 is in contact with the left end of the cathode pin 4. A metal contact wire 3 is disposed at the left end of the N-type germanium plate 2. One end of the anode pin 5 is in contact with the metal contact wire 3. One side of the N-type germanium plate 2 is connected to the inner wall of the housing 1. A first sleeve 6 and a second sleeve 7 are respectively fitted onto one end of the anode pin 5 and the cathode pin 4.

[0022] The first sleeve 6 and the second sleeve 7 are both made of rubber.

[0023] Both the anode pin 5 and the cathode pin 4 have external threads 8 circumferentially arranged at one end.

[0024] In this case, one end of the first sleeve 6 and the second sleeve 7 respectively abuts against the left and right end faces of the outer shell 1.

[0025] In this case, one end of the first sleeve 6 and the second sleeve 7 are both open, and the other end is both closed.

[0026] Both the anode pin 5 and the cathode pin 4 are cylindrical in shape.

[0027] The working principle and usage process of this utility model are as follows: First, threaded holes are provided at both the left and right ends of the outer shell 1, and external threads 8 are provided circumferentially at one end of the anode pin 5 and the cathode pin 4. The anode pin 5 and the cathode pin 4 are connected to the outer shell 1 by threads, which allows them to be disassembled. When the anode pin 5 or the cathode pin 4 is damaged, it is not necessary to replace the whole unit. Only the corresponding damaged anode pin 5 or cathode pin 4 needs to be replaced, which saves the later maintenance and usage costs.

[0028] By respectively sleeved a first sleeve 6 and a second sleeve 7 at one end of the anode pin 5 and the cathode pin 4, the anode pin 5 and the cathode pin 4 are separated and protected during transportation, so as to avoid mutual friction and wear between the anode pin 5 and the cathode pin 4 on multiple diodes during transportation. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
