Technical Field

[0001] This application relates to the field of high current probe technology, and in particular to a high current probe that can be effectively protected. Background Technology

[0002] High-current probes are specialized tools used to test high-current modules. They are typically designed with a rated current of 10-100 amps or even higher and are mainly used for testing power modules.

[0003] However, existing high-current probes do not have a protective structure, so if they fall to the ground during use, they will be damaged. Therefore, in order to correct the above defects, we propose a high-current probe that can be effectively protected. Summary of the Invention

[0004] In view of the above problems, this application provides a high-current probe that can be effectively protected, so as to solve the problem that if the high-current probe is dropped to the ground during use because it does not have a protective structure, it will be damaged.

[0005] This application provides a high-current probe that can be effectively protected, including a protective cylinder: the protective cylinder contains a probe body, and the left side of the protective cylinder is provided with a sealing cover, and the left end of the protective cylinder is provided with an annular groove, the annular groove is provided with a limiting ring, the limiting ring is fixedly connected to the side wall of the sealing cover, and the sealing cover is provided with a movable hole.

[0006] In some embodiments, a pair of limiting blocks are fixedly connected to the inner wall of the protective cylinder, and the pair of limiting blocks are symmetrically arranged about the central axis of the probe body.

[0007] In some embodiments, an insulating sleeve is fixedly connected to the outer wall of the protective cylinder, and the insulating sleeve and the side wall of the protective cylinder are provided with round holes.

[0008] In some embodiments, a plurality of bolts pass through the sidewall of the annular groove, and the sidewall of the limiting ring is provided with a threaded groove that matches the bolts.

[0012] 1. By setting up a protective cylinder, a sealing cap, and bolts, the probe body is placed inside the protective cylinder. Then, the limiting ring on the sealing cap is inserted into the annular groove, and the bolts are tightened to limit the limiting ring, thereby fixing the sealing cap. The probe body is then protected by the protective cylinder and the sealing cap.

[0013] 2. With the setting of movable hole, round hole and protective cylinder, when the probe body needs to be used, push rod through movable hole, push left side of probe body, and then compress spring on probe body, so that right end of probe body passes through round hole, thus using probe body.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The terms "comprising" and "having," and any variations thereof, in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the presence of multiples. Unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple sets" means two or more (including two sets).

[0022] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are only for the convenience of describing this application 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. Therefore, they should not be construed as limitations on this application.

[0023] Furthermore, the descriptions of directions such as the X direction, Y direction, and Z direction used to explain the operation and construction of the components in this embodiment are not absolute but relative. Although these directions are appropriate when the components are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.

[0024] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, "connection" or "linkage" in mechanical structures can refer to a physical connection, such as a fixed connection, a detachable connection, or an integral connection. In addition to referring to a physical connection, "connection" or "linkage" in circuit structures can also refer to an electrical connection or a signal connection. For example, it can be a direct connection, i.e., a physical connection, or an indirect connection through at least one intermediate component, as long as the circuit is connected. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a high-current probe that can be effectively protected, including a protective cylinder 1: the protective cylinder 1 is provided with a probe body 2, and a sealing cover 3 is provided on the left side of the protective cylinder 1, and an annular groove 4 is provided at the left end of the protective cylinder 1. A limiting ring 5 is provided in the annular groove 4, and the limiting ring 5 is fixedly connected to the side wall of the sealing cover 3. An movable hole 6 is provided on the sealing cover 3.

[0027] In the technical solution of this application embodiment, the insulation effect of the protective cylinder 1 is improved by the insulating sleeve 8. A pair of limiting blocks 7 are fixedly connected to the inner wall of the protective cylinder 1. The pair of limiting blocks 7 are symmetrically arranged about the central axis of the probe body 2. An insulating sleeve 8 is fixedly connected to the outer wall of the protective cylinder 1. Circular holes 9 are opened on the side walls of the insulating sleeve 8 and the protective cylinder 1.

[0028] In the technical solution of this application embodiment, the probe body 2 is conveniently installed and removed by bolts 10. Several bolts 10 pass through the side wall of the annular groove 4. The side wall of the limiting ring 5 is provided with a threaded groove that matches the bolts 10. Several bolts 10 are distributed in a ring about the central axis of the annular groove 4. Anti-slip texture is provided on the outer wall of the sealing cover 3 and anti-slip texture is provided on the insulating sleeve 8.

[0029] Working principle: When in use, place the probe body 2 into the protective cylinder 1, then insert the limiting ring 5 on the sealing cover 3 into the annular groove 4, and then tighten the bolt 10 to limit the limiting ring 5, thereby fixing the sealing cover 3. The probe body 2 is then protected by the protective cylinder 1 and the sealing cover 3. When the probe body 2 needs to be used, push the push rod through the movable hole 6 to push the left side of the probe body 2, thereby compressing the spring on the probe body 2, so that the right end of the probe body 2 passes through the round hole 9, thus using the probe body 2. When the probe body 2 needs to be removed, unscrew the bolt 10 to remove the sealing cover 3, and then the probe body 2 can be taken out.
