The diameter of the cylindrical portion is the same as the maximum diameter of the conical portion. When viewed along a second direction, the cross-section of the conical portion in the thickness direction is formed as a trapezoid that is wider at the top and narrower at the bottom.

[0031] First aspect of the embodiments

[0032] An embodiment of the first aspect of this application provides a housing structure. Figure 1 This is a schematic diagram of the shell structure according to an embodiment of the first aspect of this application, showing a top view of the shell structure from above; it should be noted that: Figure 1 Only a portion of the casing is shown as an example; Figure 2 It is along Figure 1 The cross-sectional view along line A-A' shows a schematic diagram of the shell structure viewed from a second direction, including a schematic diagram of the probe. Figure 3 This is another schematic diagram of the shell structure according to an embodiment of the first aspect of this application, showing a perspective view of the shell structure after being cut in the thickness direction, wherein the figure includes a schematic diagram of the probe; Figure 4 This is a schematic diagram of the housing of an embodiment of the first aspect of this application, showing a view of the housing after cross-section of the housing structure in the thickness direction.

[0033] like Figures 1 to 4As shown, the housing structure 1 may include: an outer shell 10, a metal insert 20, and an elastic sealing part 30. The outer shell 10 is provided with a probe detection hole 101 that penetrates the thickness direction A1 of the outer shell 10. The metal insert 20 is disposed in the probe detection hole 101 of the outer shell 10 in a manner that penetrates the thickness direction A1 of the outer shell 10. The elastic sealing part 30 is disposed between the metal insert 20 and the outer shell 10, and the metal insert 20 is elastically and sealingly connected to the outer shell 10 through the elastic sealing part 30.

[0034] According to the above embodiments, by providing a metal insert 20 that is elastically and tightly connected to the outer shell 10, the waterproof function of the shell structure 1 can be achieved while supporting probe detection, thereby preventing the substrate inside the outer shell 10 from short-circuiting when exposed to water.

[0035] In the embodiments of this application, such as Figures 1 to 3 As shown in the figure, the number of metal inserts 20 is three (hereinafter referred to as metal inserts 20), but this application is not limited to this, and one or more metal inserts may be included in the embodiments of this application.

[0036] In the embodiments of this application, the metal insert 20 and the outer shell 10 can be firmly connected as one unit through secondary injection molding and insert molding processes. However, this application is not limited to this. For example, it may include any structure or process that can firmly connect the metal insert 20 and the outer shell 10 as one unit.

[0037] In the embodiments of this application, such as Figure 1 As shown, the probe detection hole 101 is slightly elliptical, but this application is not limited to this. The probe detection hole 101 can be any shape that can accommodate the metal insert 20.

[0038] In this embodiment, the elastic sealing part 30 is an injection-molded component that connects the metal insert 20 and the housing 10. Utilizing its elasticity, the metal insert 20 can be moved up and down in a first direction, thereby forming different contact states with other components (e.g., detection points within the housing structure 1).

[0039] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the outer casing 10 is engaged with the elastic sealing part 30, and the elastic sealing part 30 is engaged with the metal insert 20.

[0040] The engaging connection between the outer casing 10 and the elastic sealing part 30 increases the contact area between them, making the connection between the outer casing 10 and the elastic sealing part 30 more secure. Similarly, the engaging connection between the elastic sealing part 30 and the metal insert 20 increases the contact area between them, making the connection between the elastic sealing part 30 and the metal insert 20 more secure.

[0041] Figure 5 This is a schematic diagram of a metal insert according to an embodiment of the first aspect of this application, showing a view of a metal insert after cross-sectioning the housing structure in the thickness direction; Figure 6 This is a schematic diagram of the elastic sealing portion according to an embodiment of the first aspect of this application, showing a view of the elastic sealing portion after cross-section of the housing structure in the thickness direction.

[0042] In the embodiments of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, the outer casing 10 has a first engaging portion 102 on the circumferential surface F1 of the probe detection hole 101, the elastic sealing portion 30 has a second engaging portion 301 on the outer circumferential surface F2 facing the outer casing 10, the elastic sealing portion 30 has a third engaging portion 302 on the inner circumferential surface F3 facing the metal insert 20, and the metal insert 20 has a fourth engaging portion 201 on the outer circumferential surface F4 facing the elastic sealing portion 30. The outer casing 10 and the elastic sealing portion 30 are engaged and connected through the first engaging portion 102 and the second engaging portion 301, and the elastic sealing portion 30 and the metal insert 20 are engaged and connected through the third engaging portion 302 and the fourth engaging portion 201.

[0043] In the embodiments of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, the first engaging portion 102 is formed as a groove recessed outward from the circumferential surface F1 of the probe detection hole 101, and the second engaging portion 301 is formed as a protrusion protruding outward from the outer peripheral surface F2 of the elastic sealing portion 30. The protrusion is inserted into the groove to engage the first engaging portion 102 and the second engaging portion 301, thereby engaging the outer shell 10 with the elastic sealing portion 30. The third engaging portion 302 is formed as a groove recessed outward from the inner peripheral surface F3 of the elastic sealing portion 30, and the fourth engaging portion 201 is formed as a protrusion protruding outward from the outer peripheral surface F4 of the metal insert 20. The protrusion is inserted into the groove to engage the third engaging portion 302 and the fourth engaging portion 201, thereby engaging the metal insert 20 with the elastic sealing portion 30.

[0044] The interlocking connection between the outer shell 10 and the elastic sealing part 30, and between the metal insert 20 and the elastic sealing part 30, increases the contact area between the outer shell 10 and the elastic sealing part 30, as well as between the elastic sealing part 30 and the metal insert 20, thereby making the connection between the outer shell 10, the elastic sealing part 30 and the metal insert 20 more secure.

[0045] In the embodiments of this application, such as Figure 4 As shown, the first engaging portion 102, which is formed as a groove, can be positioned approximately at the middle of the probe detection hole 101 in the thickness direction A1.

[0046] In the embodiments of this application, the first engaging portion 102, the second engaging portion 301, the third engaging portion 302, and the fourth engaging portion 201 are not limited to... Figure 4 , Figure 5 and Figure 6 The grooves or protrusions shown, and any engaging connection structures, are included in the embodiments of this application.

[0047] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the metal insert 20 includes, from top to bottom, a connecting and fixing portion 202, a cylindrical portion 203, and a conical portion 204 along the thickness direction A1. The connecting and fixing portion 202 is formed into a cylindrical shape with a diameter larger than the diameter of the cylindrical portion 203 and the maximum diameter of the conical portion 204. The diameter of the cylindrical portion 203 is the same as the maximum diameter of the conical portion 204. When viewed along the second direction A2, the cross-section of the conical portion 204 in the thickness direction A1 is formed into a trapezoid that is wider at the top and narrower at the bottom.

[0048] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the fourth engaging portion 201 may be provided on the outer periphery of the connecting fixing portion 202, that is, the fourth engaging portion 201 protrudes outward from the outer periphery of the connecting fixing portion 202.

[0049] In this embodiment, the connecting and fixing part 202, the cylindrical part 203, and the conical part 204 can be integrally formed.

[0050] In the embodiments of this application, such as Figure 2 As shown, the thickness of the connecting fixing part 202 in the first direction A1 is approximately the same as the thickness of the elastic sealing part 30 in the first direction A1 and the thickness of the outer casing 10 in the first direction A1.

[0051] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the metal insert 20 is provided with a probe insertion groove 205 that is recessed downward from the connection fixing part 202.

[0052] In this embodiment, the length of the probe insertion groove 205 in the thickness direction A1 is equal to or slightly less than the overall length of the connecting fixing part 202 and the cylindrical part 203 in the thickness direction A1.

[0053] In this way, when the probe P is inserted into the metal insert 20, the metal insert 20 can easily move downward without causing the metal insert 20 to deflect in the axial direction and thus contact the detection point.

[0054] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the probe insertion groove 205 includes a guide portion 2051 and an insertion portion 2052 from top to bottom. When viewed along the second direction A2, the cross-section of the guide portion 2051 in the thickness direction A1 is formed as a trapezoid that is wider at the top and narrower at the bottom. The insertion portion 2052 extends downward from the lower end of the guide portion into a cylindrical shape.

[0055] In this way, the probe insertion groove 205, which includes the guide portion 2051, makes it easy to insert the probe P into the probe insertion groove 205.

[0056] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the lower end of the insertion part 2052 may have a tapered part that is adapted to the lower end of the probe P. That is to say, the lower end of the insertion part 2052 is not necessarily the tapered part shown in the figure, but can be any shape structure adapted to the probe P. It may also be a cylindrical insertion part 2052 with no other structure at its lower end.

[0057] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the diameter of the cylindrical portion 203 is, for example, about 2 mm larger than the diameter of the insertion portion 2052. This allows for a more robust and secure insertion of the probe P.

[0058] According to the embodiments of this application, the housing structure 1 is provided with a metal insert 20 that is elastically and tightly connected to the outer shell 10. This allows the housing structure 1 to be waterproof while supporting probe detection, thereby preventing the substrate inside the outer shell 10 from short-circuiting when exposed to water.

[0059] Second aspect of the embodiments

[0060] An embodiment of the second aspect of this application provides an electronic product. Figure 7 This is a schematic diagram of an electronic product according to an embodiment of the second aspect of this application. Only a portion of the structure of the electronic product is shown in the diagram.

[0061] like Figure 7As shown, the electronic product 7 includes the housing structure 1 described in the embodiments of the first aspect. Since the main structure of the housing structure 1 has been described in detail in the embodiments of the first aspect, its contents are included herein and will not be repeated here.

[0062] In the embodiments of this application, such as Figure 7 As shown, the electronic product 7 may also include a substrate 2 disposed within the housing 10. The substrate 2 includes a plurality of detection points 21, and a plurality of metal inserts 20 are respectively opposed to the plurality of detection points 21 in the thickness direction A1. When the detection points 21 are circular, the minimum diameter of the conical portion 204 of the metal insert 20 is smaller than the diameter of the detection point 21. This makes it easier for the metal insert 20 to contact the detection point 21.

[0063] When electronic product 7 is in a non-testing state (or customer use state), such as Figure 7 As shown, the metal insert 20 and the detection point 21 are in a non-contact state. When the electronic product is in the production state, the probe P is inserted into the metal insert 20, and the downward pressure causes the elastic sealing part 30 to deform, thereby making the metal insert 20 contact the detection point 21 on the substrate to support the electronic product to be programmed or tested using the probe.

[0064] The above description only illustrates the composition of the electronic product related to the embodiments of this application. This application is not limited to this. The electronic product may also include other conventional compositions. For details, please refer to the relevant technology. The description is omitted here.

[0065] According to the embodiments of this application, by providing a metal insert 20 that is elastically and tightly connected to the outer casing 10, the electronic product can achieve the waterproof function of the casing structure 1 while supporting probe detection, thereby preventing the substrate inside the outer casing 10 from short-circuiting when exposed to water, which is beneficial to extending the service life of the electronic product.
