Description

Technical Field

[0001] This application relates to the field of protection technology for electronic devices, and more specifically to an electronic measuring device with a protective structure. Background Technology

[0002] In the prior art, to prevent electronic devices from being bumped or knocked, soft rubber parts are usually installed on the outer surface of the electronic devices to provide cushioning protection. However, during the use, handling, and movement of electronic devices, the edges of the slender and flat soft rubber parts are easily pried open by fingers, causing the soft rubber parts to detach from the electronic devices. This results in the soft rubber parts becoming loose and not securely fixed, thus affecting the durability of the electronic devices. Utility Model Content

[0003] This application provides an electronic measuring device with a protective structure, which aims to solve the technical problem of insecure fixation of soft rubber parts on electronic devices.

[0004] Some embodiments of this application provide an electronic measuring device with a protective structure, including:

[0005] The device body includes a front surface with a control panel and a display screen, a rear surface opposite to the front surface, and a top surface, a bottom surface, and two side surfaces connecting the front surface and the rear surface; and,

[0006] A protective component is provided, wherein the protective component is adjacent to the front end face and is sleeved around the top surface, bottom surface and two sides of the device body. The protective component is fixed to at least one of the top surface, bottom surface and two sides by a connecting part. The side of the protective component near the front end face and the top surface, bottom surface and two sides around which the protective component is sleeved are interference fit.

[0007] In some embodiments, the front end face has a width direction and a height direction with a length less than the width direction, the top surface and the bottom surface are located in the width direction of the front end face, and the two side surfaces are located in the height direction of the front end face;

[0008] The connecting part includes a first connector and a first connecting groove, wherein the first connector and the first connecting groove are interference-fitted between the protective member and the top surface of the device body.

[0009] In some embodiments, the first connector is disposed on the top surface of the protective member facing the device body, the first connecting groove is disposed on the top surface, and the first connector and the first connecting groove are interference-fitted on the side of the protective member facing the top surface.

[0010] In some embodiments, the connection further includes a screw and a nut, the screw and the nut being threadedly connected between the protective member and the bottom surface of the device body.

[0011] In some embodiments, the nut is disposed on the bottom surface, the protective member has a countersunk hole corresponding to the position of the nut, the screw passes through the countersunk hole and is threadedly connected to the nut, and the nut of the screw is located inside the countersunk hole.

[0012] In some embodiments, a positioning part is further provided between the protective member and the bottom surface of the device body;

[0013] The positioning part includes a second connector and a second connecting groove. The second connector and the second connecting groove are engaged between the protective member and the bottom surface of the device body to align the screw and the nut.

[0014] In some embodiments, the connecting portion is located between the front end face and the rear end face.

[0015] In some embodiments, the connecting portion further includes a third connector and a third connecting groove, wherein the third connector and the third connecting groove are non-interference-fitted between the protective member and the side of the device body.

[0016] In some embodiments, the third connector is disposed on the side of the protective member facing the device body, the third connecting groove is disposed on the side, and the third connector and the third connecting groove are non-interference-fitted on the side of the protective member facing the side.

[0017] In some embodiments, the front end face edge of the device body has a protrusion that protrudes in a direction away from the rear end face, and the protective member extends from the side near the front end face to a position where the protrusion is away from the front end face and flips to cover the protrusion.

[0018] According to the electronic measuring device with a protective structure in the above embodiments, this application achieves an interference fit between the side of the protective member near the front end face and the top surface, bottom surface, and two side surfaces around which the protective member is encircled. This allows the side of the protective member near the front end face to be connected and fixed to the device body along the circumference of the front end face, thereby preventing the protective member from detaching from the device body on the side near the front end face. Simultaneously, the protective member is fixed to at least one of the top surface, bottom surface, and two side surfaces via a connecting portion, allowing the side of the protective member near the rear end face to be adhered to or fixed to the device body through the connecting tension of the connecting portion, thus preventing the protective member from detaching from the device body on the side near the rear end face. Therefore, through the interference fit between the front end face of the device body and the protective member, and the tensioning effect of the connecting portion on the protective member, this application makes it difficult for the protective member to detach from either the front end face or the rear end face of the device body, thus making it difficult for the two sides of the protective member to be pried open by fingers, improving the durability of the electronic measuring device.

Specific Implementation

[0028] The present application will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] To make the connection between flexible plastic parts and electronic devices more secure, this application provides an electronic measuring device with a protective structure, such as... Figures 1 to 5As shown, the electronic measuring device with a protective structure may include a device body 1 and a protective element 2. The device body 1 may be an electronic device such as an oscilloscope, waveform generator, spectrum analyzer, electronic load, multimeter, or source meter. This application does not impose any special restrictions on the specific type of device body 1. These device bodies 1 may include a front surface 11 with a control panel and a display screen, a rear surface 12 opposite to the front surface 11, and a top surface 13, a bottom surface 14, and two side surfaces 15 connecting the front surface 11 and the rear surface 12. The control panel may have control devices such as knobs, buttons, and levers, and the display screen may be used to display measurement data, graphics, and other interfaces. The protective element 2 may be adjacent to the front surface 11 and encircle the top surface 13, bottom surface 14, and two side surfaces 15 of the device body 1. The protective element 2 may be fixed to at least one of the top surface 13, bottom surface 14, and two side surfaces 15 of the device body 1 by a connecting part 3. The side of the protective element 2 closest to the front surface 11 and the top surface 13, bottom surface 14, and two side surfaces 15 encircled by the protective element 2 are interference-fitted. The material of the protective component 2 can be soft rubber, silicone or plastic, and this application does not impose any special restrictions on the specific material of the protective component 2.

[0032] This application achieves an interference fit between the side of the protective member 2 near the front face 11 and the top surface 13, bottom surface 14, and two side surfaces 15 around which the protective member 2 is encircled. This allows the side of the protective member 2 located near the front face 11 to be connected and fixed to the device body 1 along the circumference of the front face 11, thereby preventing the protective member 2 from detaching from the device body 1 on the side near the front face 11. Simultaneously, the protective member 2 is fixed to at least one of the top surface 13, bottom surface 14, and two side surfaces 15 via a connecting part 3. This allows the side of the protective member 2 near the rear face 12 to be adhered to or fixed to the device body 1 through the connecting and tightening action of the connecting part 3, thereby preventing the protective member 2 from detaching from the device body 1 on the side near the rear face 12. Therefore, through the interference fit between the front end face of the device body 1 and the protective component 2, and the tensioning effect of the connecting part 3 on the protective component 2, the protective component 2 is not easy to detach from the front end face 11 and the rear end face 12 of the device body 1, thereby making it difficult for the two sides of the protective component 2 to be pried open by fingers, thus improving the durability of the electronic measuring equipment.

[0033] The protective element 2 can either encircle the entire surface of the device body 1 or only a portion of its surface. For example, when the device body 1 is a handheld electronic load, the protective element 2 can encircle the entire handheld electronic load. Or, for example... Figure 1As shown, when the device body 1 is the source meter, both the control panel and the display screen are located on the front face 11 of the source meter head, and the protective element 2 can be looped around the source meter head. This application does not impose any special limitation on the size of the area of ​​the device body 1 covered by the protective element 2. The following embodiments will be illustrated using the device body 1 as the source meter.

[0034] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the front end face 11 of the device body 1 has a width direction W and a height direction H whose length is less than the width direction W. The entire device body 1 also has a length direction L perpendicular to the width direction W and the height direction H. The top surface 13 and the bottom surface 14 are located in the width direction W of the front end face 11, and the two side surfaces 15 are located in the height direction H of the front end face 11. The connecting part 3 may include a first connector 31 and a first connecting groove 32, which are interference-fitted between the protective member 2 and the top surface 13 of the device body 1.

[0035] The interference fit between the first connector 31 and the first connecting groove 32 ensures that the protective component 2 is securely connected to the equipment body 1, preventing it from easily detaching from the equipment body 1 and thus guaranteeing the reliability of the connection of the protective component 2. Figure 3 As shown, when the protective component 2 is interference-fitted with the device body 1, the interference fit of the first connector 31 near the front end face 11 allows the first connector 31 to engage within the first connecting groove 32, while the interference fit of the first connector 31 near the rear end face 12 pulls the protective component 2 tightly onto the device body 1, thus preventing fingers from easily prying off the edges of the protective component 2. The interference fit between the protective component 2 and the device body 1 via the first connector 31 and the first connecting groove 32 can be provided not only on the top surface 13, but also on the bottom surface 14 and the two sides 15, thereby better preventing the protective component 2 from detaching from the device body 1. This application does not impose any special restrictions on the specific locations of the first connector 31 and the first connecting groove 32.

[0036] In some embodiments, such as Figure 6 and Figure 7As shown, the first connector 31 is disposed on the side of the protective member 2 facing the top surface 13 of the device body 1, and the first connecting groove 32 is disposed on the top surface 13. The first connector 31 and the first connecting groove 32 are interference-fitted on the side of the protective member 2 facing the top surface 13. In this way, when the protective member 2 is fitted around the device body 1, the connection structure between the protective member 2 and the device body 1 is not visible from the outside, thus making the appearance of the electronic measuring device smoother and more aesthetically pleasing. Of course, in other embodiments, the first connector 31 may also protrude from the outer surface of the protective member 2, so that when installing the protective member 2, the protruding first connector 31 can be pressed to make the first connector 31 interference-fitted into the first connecting groove 32.

[0037] The first connector 31 can be a single, cylindrical or block-shaped structure, and the first connecting groove 32 can be a single groove structure corresponding to the cylindrical or block structure, or it can be a waist-shaped groove structure provided along the width direction W. Alternatively, the first connector 31 and the first connecting groove 32 can also be elongated structures provided along the width direction W. This application does not impose any special restrictions on the specific number and shape of the first connector 31 and the first connecting groove 32.

[0038] Furthermore, in some embodiments, such as Figure 6 and Figure 7 As shown, the connecting part 3 may also include a screw 33 and a nut 34, which are threadedly connected between the protective member 2 and the bottom surface 14 of the device body 1. The threaded connection of the screw 33 and nut 34 also securely fixes the protective member 2 to the device body 1. Since the bottom surface 14 is not easily visible during use, placing the screw 33 and nut 34 on the bottom surface 14 makes the electronic measuring device more aesthetically pleasing. Of course, the threaded connection between the protective member 2 and the device body 1 via the screw 33 and nut 34 can be placed not only on the bottom surface 14, but also on the top surface 13 and the two sides 15, thereby better preventing the protective member 2 from detaching from the device body 1. This application does not impose any special restrictions on the specific location of the screw 33 and nut 34.

[0039] In some embodiments, such as Figure 3 and Figure 4As shown, the nut 34 can be installed on the bottom surface 14 by means of heat fusion, bonding, or pre-embedding. The protective member 2 has a countersunk hole 20 corresponding to the position of the nut 34. The screw 33 passes through the countersunk hole 20 and is threadedly connected to the nut 34. The nut of the screw 33 is located inside the countersunk hole 20. Thus, when the screw 33 is screwed into the nut 34 at the bottom of the equipment body 1, the nut of the screw 33 can be hidden inside the countersunk hole 20, thereby maintaining the flatness of the bottom surface 14. In other embodiments, depending on the different lengths of the equipment body 1 in the width direction W, multiple screws 33 and multiple nuts 34 can be provided between the equipment body 1 and the protective member 2. These screws 33 and nuts 34 can be spaced apart along the width direction W on the bottom surface 14 to increase the reliability of the connection of the protective member 2. In this application, since the protective member 2 is looped around the equipment body 1, the protective members 2 at both ends of the bottom surface 14 in the width direction W are fixed. Therefore, a set of screws 33 and nuts 34 can be provided at the middle position of the bottom surface 14. This application does not impose any special restrictions on the specific number of screws 33 and nuts 34.

[0040] In some embodiments, such as Figure 6 and Figure 7 As shown, a positioning part 4 can also be provided between the protective component 2 and the bottom surface 14 of the equipment body 1. The positioning part 4 can include a second connector 41 and a second connecting groove 42. The second connector 41 and the second connecting groove 42 are engaged between the protective component 2 and the bottom surface 14 of the equipment body 1 so that the screw 33 and the nut 34 are aligned. After the second connector 41 and the second connecting groove 42 are connected and fixed, the countersunk hole 20 on the protective component 2 can be aligned with the nut 34 on the equipment body 1, thereby facilitating the screw 33 to be screwed in. In order to make it easier for the second connector 41 to be engaged in the second connecting groove 42, the second connector 41 and the second connecting groove 42 can adopt a non-interference fit, so that the protective component 2 can be quickly connected to the bottom surface 14 of the equipment body 1. One or more second connectors 41 and second connecting grooves 42 can be provided between the equipment body 1 and the protective component 2. This application does not impose any special limitation on the specific number of second connectors 41 and second connecting grooves 42.

[0041] Regardless of whether the connecting part 3 adopts an interference fit between the first connector 31 and the first connecting groove 32, or a threaded fit between the screw 33 and the nut 34, the connecting part 3 can securely fix the protective member 2 to the equipment body 1. In some embodiments, such as Figure 3As shown, the connecting part 3 can be located between the front end face 11 and the rear end face 12. For example, the connecting part 3 can be positioned centrally between the front end face 11 and the rear end face 12. In this way, the connecting part 3 can tighten the protective member 2 near both the front end face 11 and the rear end face 12, thereby preventing the protective member 2 from detaching from the device body 1. Of course, in other embodiments, the connecting part 3 can also be located at the rear end face 12, so that the protective member 2 is fixedly connected to both the front end face 11 and the rear end face 12 of the device body 1. This application does not impose any special restrictions on the specific location of the connecting part 3 between the front end face 11 and the rear end face 12.

[0042] In some embodiments, such as Figure 5 As shown, the connecting part 3 may further include a third connecting head 35 and a third connecting groove 36, which are non-interference-fitted between the protective member 2 and the side surface 15 of the device body 1. Since the height of the side surface 15 of the device body 1 is less than the length of the top surface 13 and the bottom surface 14, the rigidity of the protective member 2 on the side surface 15 is greater than that on the top surface 13 and the bottom surface 14, making it less likely for the edge of the protective member 2 on the side surface 15 of the device body 1 to detach from the device body 1. Therefore, by setting the third connecting head 35 and the third connecting groove 36 to a non-interference-fitting structure, the protective member 2 is easier to install on the device body 1. In other embodiments, when the height of the side surface 15 of the device body 1 is too large, the third connecting head 35 and the third connecting groove 36 may also adopt an interference-fitting structure or a threaded connection structure of screw 33 and nut 34. This application does not impose any special restrictions on the specific structural form of the connecting part 3 between the device body 1 and the protective member 2 at the side surface 15.

[0043] In some embodiments, such as Figure 6 and Figure 7 As shown, the third connector 35 is located on the side 15 of the protective member 2 facing the device body 1, and the third connecting groove 36 is located on the side 15. The third connector 35 and the third connecting groove 36 are non-interference-fitted on the side of the protective member 2 facing the side 15. In this way, when the protective member 2 is fitted around the device body 1, the connection structure between the protective member 2 and the device body 1 is not visible from the outside, thus making the appearance of the electronic measuring device smoother and more aesthetically pleasing. Of course, in other embodiments, the third connector 35 may also protrude from the outer surface of the protective member 2, so that when installing the protective member 2, the protruding third connector 35 can be pressed to make the third connector 35 non-interference-fitted into the third connecting groove 36.

[0044] Similarly, the third connector 35 can be a single, cylindrical or block-shaped structure, and the third connecting groove 36 can be a single groove structure corresponding to the cylindrical or block structure, or a waist-shaped groove structure provided along the height direction H. Alternatively, the third connector 35 and the third connecting groove 36 can also be elongated structures provided along the entire height direction H. This application does not impose any special restrictions on the specific number and shape of the third connector 35 and the third connecting groove 36.

[0045] In some embodiments, such as Figure 3 and Figure 5 As shown, the edge of the front face 11 of the device body 1 may have a protrusion 5 that protrudes in a direction away from the rear face 12. The protective member 2, on the side near the front face 11, may extend to a position where the protrusion 5 is away from the front face 11 and flip to cover the protrusion 5. Thus, the protective member 2 can cover and hook the protrusion 5 of the device body 1 at the position of the front face 11, which not only allows the protective member 2 to have an interference fit with the device body 1 on the front face 11 side, but also makes the front face 11 of the electronic measuring device more aesthetically pleasing after the protective member 2 covers the protrusion 5.

[0046] When installing the protective component 2, it can be fitted onto the front face 11 of the device body 1 from the rear end face 12 side. After the protrusion 5 is fitted onto the front face 11 of the protective component 2 and interference fits, the first connector 31 is interference-fitted into the first connecting groove 32, the second connector 41 is engaged into the second connecting groove 42, and the third connector 35 is engaged into the third connecting groove 36. Finally, the screw 33 is screwed into the nut 34, so that the protective component 2 is connected to the bottom surface 14 of the device body 1 through the threaded engagement of the screw 33 and the nut 34, thus completing the assembly of the protective component 2. After assembly, the protective component 2 located on the two sides of the front end face 11 and the rear end face 12 of the device body 1 is not easily pried off, thereby improving the durability of the electronic measuring equipment.
