Description

Technical Field

[0001] The utility model relates to the technical field of oscilloscope probes, in particular to a fast-splitting differential probe. Background Art

[0002] A differential probe is a type of measurement probe for an oscilloscope. Probes can be generally divided into two types: passive probes and active probes. Users of wide-bandwidth oscilloscopes and active probes also need to choose between single-ended probes and differential probes. The pair of traces that carry differential signals is called differential traces. Differential probes have therefore become a mainstream accessory for modern oscilloscopes.

[0003] However, the connection between the oscilloscope probe and the oscilloscope in the prior art is usually to directly insert the plug at one end of the probe into the jack on the oscilloscope. This plug-in method is usually not very firm. In the event of some collision or some unexpected situations, it is likely to cause the connection between the two to become unstable. Therefore, it does not meet the existing needs. We propose a quick-split differential probe. Utility Model Content

[0004] The utility model provides a fast-detachable differential probe, which has the beneficial effect of effectively fixing an oscilloscope and an oscilloscope probe in a fixed connection by plugging and rotating them during installation, thereby solving the problem mentioned in the above background technology that the connection between the oscilloscope components after connection may be unstable when encountering some collisions or some unexpected situations.

[0005] The utility model provides the following technical solutions: a fast-disassembled differential probe, comprising a probe assembly and an oscilloscope assembly, wherein the probe assembly and the oscilloscope assembly are connected via a connecting assembly, and data transmission is achieved between the probe assembly and the oscilloscope assembly via the plug-in port and the data connection slot, a sliding rod is arranged in the plug-in port, one end of the sliding rod is plugged into a data connection plug-in block, a fixing assembly is arranged in the sliding rod, the fixing assembly comprises a fixing block, and the fixing block is used to be plugged into the data connection plug-in block.

[0007] As an optional solution for a quick-detachable differential probe described in the utility model, the oscilloscope assembly includes an oscilloscope housing, a connection port is installed at one end of the oscilloscope housing, a data connection plug is fixedly connected to the connection port, and the data connection plug is used to be plugged into the data connection slot.

[0008] As an optional solution for a quick-detachable differential probe described in the utility model, the connecting component includes a slide groove and a circular groove opened on the plug-in port, the slide rod is slidably connected in the slide groove, one end of the slide rod is inserted in the connecting groove, and the connecting groove is opened in the connecting port.

[0009] As an optional solution for a quick-detachable differential probe described in the utility model, one side of the sliding rod is fixedly connected to a tooth block, the tooth block is meshingly connected to a gear, the gear is rotatably connected in the circular groove, one side of the gear is meshingly connected to a tooth groove, and the tooth groove is opened on the connection port.

[0010] As an optional solution for a fast-disassembly differential probe described in the utility model, the fixing component includes a mounting groove, the fixing block is elastically connected to the mounting groove via a spring, and one end of the fixing block is used to be inserted into the fixing groove.

[0014] 1. The quick-detachable differential probe has a connection component design. When the data connection plug is inserted into the data connection slot, the toothed meshing gear on the data connection plug rotates in the circular groove. The rotation of the gear can drive the slide bar meshed with it to slide in the slide groove, so that one end of the slide bar is inserted into the connection slot. This plug-in design can preliminarily connect the connection port and the plug-in port to ensure the stability of the connection between the two.

[0015] 2. The quick-detachable differential probe has a fixed component design. When the slide bar is inserted into the connecting slot, the fixed block inside the slide bar is always in contact with the connecting slot under the action of the spring. At this time, the spring always applies a certain pressure to the fixed block. The plug-in port is further rotated until the fixed block is aligned with the fixed slot. At this time, the fixed block will be directly inserted into the fixed slot under the action of the spring. Because the connecting component and the fixed component are symmetrically designed in the plug-in port, this connection can effectively ensure the stability of the connection between the probe component and the oscilloscope component, and prevent the oscilloscope components from being unstable in unexpected situations.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] This embodiment is intended to help solve the problem that the connection between the connected oscilloscope components may become unstable when encountering some collisions or some unexpected situations. Please refer to Figure 1-8 A fast-split differential probe includes a probe assembly 1 and an oscilloscope assembly 2. The probe assembly 1 is connected to the oscilloscope assembly 2 via a connecting assembly 3. Data transmission is achieved between the probe assembly 1 and the oscilloscope assembly 2 by plugging in a plug-in port 103 and a data connection slot 104. A slide bar 302 is provided in the plug-in port 103. One end of the slide bar 302 is plugged in a data connection plug-in block 203. A fixing assembly 4 is provided in the slide bar 302. The fixing assembly 4 includes a fixing block 402. The fixing block 402 is used to be plugged in the data connection plug-in block 203.

[0028] Data transmission can be achieved through the connection between the plug port 103 and the data connection plug block 203, so that the data collected by the probe assembly 1 can be transmitted to the oscilloscope. The slide bar 302 located in the plug port 103 is inserted into the connection groove 307 of the connection port 202, and the fixing block 402 in the slide bar 302 is inserted into the fixing groove 407 in the connection port 202, so that the probe assembly 1 and the oscilloscope assembly 2 can be effectively connected and fixed, and the oscilloscope components after connection can be effectively prevented from being unstable in unexpected situations.

[0029] The probe assembly 1 includes a probe housing 101, one side of the probe housing 101 is fixedly connected to a zero-live connection cable 102, the other side of the zero-live connection cable 102 is fixedly connected to a plug port 103, and a data connection slot 104 is provided in the plug port 103, and the data connection slot 104 is used to connect the oscilloscope assembly 2.

[0030] The oscilloscope assembly 2 includes an oscilloscope housing 201 . A connection port 202 is installed at one end of the oscilloscope housing 201 . A data connection plug block 203 is fixedly connected to the connection port 202 . The data connection plug block 203 is used to be plugged into the data connection slot 104 .

[0031] The neutral-live connection cable 102 can obtain certain data by connecting to the object to be detected, and transmit the data to the oscilloscope through the data connection plug-in block 203 of the plug-in port 103.

[0032] The connection component 3 includes a slide groove 301 and a circular groove 303 provided on the plug port 103 . A slide rod 302 is slidably connected in the slide groove 301 . One end of the slide rod 302 is plugged into a connection groove 307 . The connection groove 307 is provided in the connection port 202 .

[0033] A tooth block 306 is fixedly connected to one side of the slide bar 302, and the tooth block 306 is meshed with a gear 304. The gear 304 is rotatably connected in the circular groove 303. A tooth groove 305 is meshed on one side of the gear 304, and the tooth groove 305 is provided on the connection port 202. When the data connection plug 203 is inserted into the data connection slot 104, the tooth groove 305 provided on the data connection plug 203 meshes with the gear 304 and rotates in the circular groove 303. The rotation of the gear 304 can drive the slide bar 302 meshed with it to slide in the slide slot 301, so that one end of the slide bar 302 is inserted into the connection slot 307. This plug-in design can preliminarily connect the connection port 202 and the plug port 103, and ensure the stability of the connection between the two.

[0034] The fixing assembly 4 includes a mounting groove 401 , in which a fixing block 402 is elastically connected via a spring 403 , and one end of the fixing block 402 is used to be inserted into a fixing groove 407 .

[0035] When the slide bar 302 is inserted into the connecting groove 307, the fixing block 402 located in the slide bar 302 is always in contact with the connecting groove 307 under the action of the spring 403. At this time, the spring 403 always applies a certain pressure to the fixing block 402, and the plug-in port 103 is further rotated until the fixing block 402 is aligned with the fixing groove 407. At this time, the fixing block 402 will be directly inserted into the fixing groove 407 under the action of the spring 403. Because the connecting component 3 and the fixing component 4 are symmetrically designed in the plug-in port 103, this connection can effectively ensure the stability of the connection between the probe component 1 and the oscilloscope component 2, and prevent the oscilloscope components from being unstable in unexpected situations after connection.

[0036] One side of the fixed block 402 is fixedly connected to a limiting plate 404, and the limiting plate 404 is slidably connected in the mounting groove 401. The design of the limiting plate 404 effectively prevents the fixed block 402 from excessively popping out under the action of the spring 403 and causing it to be unable to be recovered, thereby improving the integrity of the structure.

[0037] One end of the fixed block 402 is provided with a No. 1 inclined surface 405, and one end of the fixed block 402 is fixedly connected to a pulling rod 406. When it is necessary to release the connection between the probe assembly 1 and the oscilloscope assembly 2, the fixed block 402 can be effectively pulled out of the fixing groove 407 by stretching the pulling rod 406. At this time, the sliding rod 302 can slide freely in the connecting groove 307. This design can quickly realize the connection and disassembly of the probe assembly 1 and the oscilloscope assembly 2, thereby ensuring the efficiency of the detection.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
