Description

Technical Field

[0001] The present application relates to the technical field of digital oscilloscopes, and in particular to a protection device for a plug socket of a digital oscilloscope. Background Art

[0002] A digital oscilloscope is an instrument used for data acquisition. A digital oscilloscope usually uses cables to transmit data. During use, the digital oscilloscope is generally connected to other devices through a wire socket. However, the socket is usually protruding from the outside of the digital oscilloscope, and there is no corresponding protection device to protect the wire socket. After the line is connected, it is very easy to pull the wiring due to accidental touch, causing the connection to fall off, affecting use. Therefore, a wire socket protection structure that can prevent falling off is needed.

[0003] Compared with the actual use process, the existing digital oscilloscopes currently have one method of directly inserting the plug wire into the jack of the oscilloscope. However, this connection and fixing method will cause the interface to loosen and the connection to be unstable after docking after long-term use. This makes it easy for the connecting wire to be disconnected when the oscilloscope is in use, thus affecting the normal use of the oscilloscope.

[0004] Therefore, in order to solve the above problems, the present application provides a protection device for a digital oscilloscope plug socket.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 4A protection device for a plug hole of a digital oscilloscope comprises an oscilloscope body 1, three docking holes 2 are provided at the bottom of the outer side of one end of the oscilloscope body 1, a protection tube 3 is slidably embedded in the inner side of the plurality of docking holes 2, a plurality of buffering grooves 5 are provided on the inner wall surface of the protection tube 3, a connecting slider 7 is slidably embedded in one end of the inner side of the buffering groove 5, one end of the connecting slider 7 is connected to a rebound spring 6 at the other end inside the buffering groove 5, in order to enable the protection tube 3 to slide out of the outer side of the wire 4 and reset at the same time, thereby realizing the protection of the wire 4, a wire 4 is slidably embedded in the inner side of the protection tube 3, one end of the plurality of connecting sliders 7 is connected to the outer side of the wire 4, a plurality of clamping grooves 8 are provided on the inner side of the docking hole 2, and a clamping spring 6 is connected at one end of the inner side of the clamping groove 8 Spring 9, one end of the clamping spring 9 is slidably embedded in the inner side of the clamping slide groove 8 with a clamping slider 10, and one end of the clamping slider 10 is welded with an inclined plate 11. In order to protect the docking jack and realize the protection of the docking jack at the same time, the height of the several inclined plates 11 is the same as the opening height of the clamping slide groove 8, a protective tube bottom groove 12 is opened at one end of the inner side of the docking hole 2, and the inner side opening diameter of the docking hole 2 is the same as the inner side opening diameter of the protective tube bottom groove 12, a wire docking jack 13 is opened in the middle of one end of the inner side of the protective tube bottom groove 12, and the inner side opening diameter of the wire docking jack 13 is the same as the diameter of the wire 4, an adjusting knob 14 is installed on the outer side of one end of the oscilloscope body 1, and a display screen 15 is installed on one side of the adjusting knob 14 on the outer surface of one end of the oscilloscope body 1.

[0023] Working principle: first, place the oscilloscope body 1 at the designated position, then the operator inserts the protection tube 3 into the docking hole 2 opened at the bottom of the outer side of one end of the oscilloscope body 1, and then continues to push the protection tube 3 into the docking hole 2. At that time, as the protection tube 3 continues to go deeper, one end of the protection tube 3 will contact one end of the plurality of funnel-shaped inclined plates 11, and as the protection tube 3 goes deeper, it will push the plurality of conical funnel-shaped inclined plates 11 to slide outward, and at the same time drive the clamping slider 10 welded thereto to slide inside the clamping slot 8, until the plurality of inclined plates 11 also slide into the clamping slot 8, and since the opening height of the clamping slot 8 is the same as the height of the inclined plate 11, the inclined plate 11 can also completely enter the clamping slot 8;

[0024] Then the protection tube 3 will pass through the clamping slide groove 8 and enter the inner side of the protection tube bottom groove 12 connected to the docking hole 2, until one end of the protection tube 3 hits the bottom of the protection tube bottom groove 12, at which time the protection tube bottom groove 12 will limit the protection tube 3, and then the operator will push the wire 4 again, and the wire 4 will drive the outer side of the connecting sliders 7 to slide inside the buffer slide groove 5 opened on the inner side of the protection tube 3, until one end of the wire 4 is engaged with the wire docking socket 13 opened at one end of the inner side of the protection tube bottom groove 12, and then the wire docking and fixing can be completed, and the removal is also the operator pulling the wire 4 outward to remove the wire 4 from the wire docking socket 13 After pulling it out, the protective tube 3 can be pulled out from the bottom groove 12 of the protective tube to complete the removal of the wire 4. As the protective tube 3 detaches from the docking hole 2 and the bottom groove 12 of the protective tube, the clamping spring 9 on the inside of the clamping slide groove 8 will push the clamping slider 10 to reset, thereby protecting the wire docking jack 13 through the inclined plate 11 welded at one end of the clamping slider 10, and the rebound spring 6 on the inside of the buffer slide groove 5 will also push the several connecting sliders 7 connected to the outside of the wire 4 to reset, so that the protective tube 3 protects the wire 4.
