Description

Technical Field

[0001] This utility model relates to the field of shock-resistant devices for electronic measuring instruments, specifically to a shock-resistant device for electronic measuring instruments. Background Technology

[0002] Multimeters, as a type of electronic measuring instrument, are frequently used in the testing of electronic devices. Generally, multimeters have clip-on or pointer-type testing heads. Clip-on heads are used when testing larger objects, while pointer-type heads are used for smaller components such as circuit boards. When using a pointer-type testing head, the head needs to be held with both hands, and the multimeter is placed on a table. Moving the pointer-type testing head may pull the cable, causing the multimeter to move. If the multimeter falls from the table, the resulting shock may damage the internal components. Therefore, this paper proposes a shockproof device for electronic measuring instruments to address this issue. Utility Model Content

[0025] An embodiment of a preferred technical solution for a shockproof device for electronic measuring instruments includes the following:

[0026] Refer to the instruction manual appendix Figure 1 As shown: It includes a multimeter assembly 1, and a shockproof housing 3 is provided on the outer surface of the multimeter assembly 1. Cable anti-detachment clamps 2 are provided on the plug ports of the multimeter assembly 1.

[0027] Refer to the instruction manual appendix Figure 2 As shown: The multimeter assembly 1 includes a meter body 11, two cable plugs 13 plugged into the plug port on the upper surface of the meter body 11, and the other end of the cable plugs 13 is connected to a cable 14. The end of each cable 14 is connected to a pointer-type test head 12.

[0028] Refer to the instruction manual appendix Figure 5As shown: The cable anti-detachment clamp 2 includes a cylindrical clamp 21 fixed on the upper end face of the plug-in port, and a rubber inner ring 23 fixedly connected to the inner ring surface of the cylindrical clamp 21 by adhesive. A convex surface 22 is provided below the inner ring surface of the rubber inner ring 23, and the inner ring surface of the convex surface 22 is in contact with the surface of the cable plug 13 inserted into the plug-in port.

[0029] Refer to the instruction manual appendix Figure 3 As shown: The shockproof housing 3 includes four corner pads 31 fixed at the four corners of the watch body 11. Two rubber vertical strips 32 are provided on the left and right sides of the watch body 11, and two rubber horizontal strips 33 are provided on the front and back sides of the watch body 11. The front and back ends of the rubber vertical strips 32 are connected to the front and back surfaces of the corner pads 31 that are close to each other, and the left and right ends of the rubber horizontal strips 33 are connected to the left and right surfaces of the corner pads 31 that are close to each other.

[0030] Refer to the instruction manual appendix Figure 5 As shown: the bottom surface of the cylindrical hoop 21 is connected to the upper surface of the plug-in port on the upper surface of the body 11, and the inner diameter of the cylindrical hoop 21 is the same as the inner diameter of the plug-in port; multiple transversely arranged grooves are opened on the inner ring surface of the convex surface 22 to increase the friction with the outer surface of the cable plug 13.

[0031] Refer to the instruction manual appendix Figure 4 As shown: Each corner pad 31 has an internal chamber 34, and the inner cavity of the chamber 34 is filled with aerogel. (Refer to the attached instruction manual.) Figure 3 As shown: the edges of the corner pads 31 are fixedly connected to the four edges of the watch body 11 on their respective sides. The vertical surfaces of the rubber strips 32 are fixedly connected to the vertical surfaces of the watch body 11 on their respective sides. The horizontal surfaces of the rubber strips 33 are fixedly connected to the vertical surfaces of the watch body 11 on their respective sides.

[0032] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0033] When using the pointer-type test head 12 to perform short-circuit and open-circuit tests on circuit boards or electrical components, the pointer-type test head 12 is held with both hands, and the watch body 11 is placed on the table. During the movement of the pointer-type test head 12, there is a possibility that the cable 14 will be pulled and the watch body 11 will move. If the watch body 11 falls from the table, the outer surface of the corner pad 31 will contact the ground. The cavity in the temporal part of the corner pad 31 and the aerogel filling it will cushion the four corners and edges of the watch body 11, preventing the vibration generated by the fall from being transmitted to the components inside the watch body 11. At the same time, during the fall of the watch body 11, the section of the cable plug 13 inserted into the plug port will make close contact with the convex surface 22 of the inner ring of the rubber inner ring 23. The large friction force applied by the convex surface 22 and the groove will prevent the cable plug 13 from being easily pulled out of the plug, thus playing a pulling and cushioning role when the watch body 11 falls, preventing the watch body 11 from falling too fast and generating greater vibration.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
