[0002] With the development of technology, the market has higher and higher requirements for the electrical safety performance of electronic products. Even for electronic products with voltages such as 12V or 24V that have strong and weak electrical isolation settings and possess certain electrical safety performance, in order to avoid the situation of electric shock caused by the failure of strong and weak electrical isolation, from a structural perspective, it is also necessary to perform secondary isolation on the easily conductive parts of electronic products to further improve the electrical safety performance of electronic products. For example, for an electronic device with an antenna, it is necessary to perform secondary isolation on its easily conductive parts. At the same time, when setting the isolation structure for these parts of electronic products that require secondary isolation, it is necessary to consider production assembly and after-sales disassembly problems, and also meet the electrical safety requirements. Some of the existing such structures can meet the electrical safety requirements but are difficult to assemble and disassemble, some are easy to assemble and disassemble but cannot meet the electrical safety requirements, and there is also a part that needs to rely on the structures of other relevant components or parts in the product to meet the electrical safety requirements. For example, in the antenna installation structure of the SMA interface, it is also necessary to install a locknut and a gasket for pressing and anti-loosening, and the disassembly and assembly are relatively complex, resulting in low production assembly efficiency.

Detailed Embodiments

[0029] To facilitate the understanding of the present invention by those skilled in the art, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0030] Referring to Figures 1 to 7, an antenna assembly structure with high safety provided by the present invention includes a box body 1, a main board 13 arranged in the box body 1, an external interface 2 arranged on the main board 13, and an antenna 3 electrically connected to the external interface 2. The box body 1 includes a bottom shell 11 and a top cover 12, and further includes a sleeve 4 arranged on one side of the box body 1. The external interface 2 extends out of the box body 1, and the sleeve 4 surrounds the external interface 2 inside. A plurality of clamping parts 31 are evenly arranged on the outer wall of the end of the antenna 3 connected to the external interface 2, and a clamping boss 41 corresponding to the clamping part 31 is arranged on the inner wall of the sleeve 4; a spring 5 is sleeved on the external interface 2. When the antenna 3 is connected to the external interface 2, one end of the spring 5 contacts the box body 1, and the other end of the spring 5 contacts the antenna 3.

[0031] The clamping part 31 and the clamping boss 41 limit the freedom degree in the reverse direction of the insertion of the antenna 3, and there is a circumferential pressing effect between the entire circle of the assembly surface of the clamping boss 41 on the inner side of the sleeve 4 and the clamping part 31 of the antenna 3, which plays a role of radial pressing and positioning for the assembly of the antenna 3. The spring 5 directly contacts the bottom surface of the antenna 3 (that is, the frontmost plane of the SMA interface) to press and avoid axial loosening.

[0032] A plurality of positioning ribs 32 are further arranged on the outer wall of the end of the antenna 3 connected to the external interface 2, and the sleeve 4 is provided with a plurality of positioning grooves 42 matching the positioning ribs 32 for the positioning ribs 32 to insert. The inlay fit between the two limits the freedom degree of the left-right rotation and the insertion direction of the entire assembly. Specifically, two positioning ribs 32 are provided, and the two positioning ribs 32 are arranged oppositely, that is, they are arranged oppositely with reference to the central axis of the antenna 3. The two positioning ribs 32 divide the plurality of clamping parts 31 into two parts, and each part is evenly provided with 4 clamping parts 31 (that is, arranged at equal intervals).

[0033] A guiding opening 43 is arranged at one end of the positioning groove 42 away from the box body 1, and a limiting head 34 corresponding to the guiding opening 43 is arranged at one end of the positioning rib 32 away from the box body 1. The guiding opening 43 is specifically trapezoidal (or called trumpet-shaped), the narrowest part of which is consistent with the width of the positioning groove 42, and the widest part is wider than the width of the positioning groove 42. With such a design, the antenna 3 can be inserted more easily during assembly, without having to be very accurate, which can save assembly time.

[0034] The end of the positioning rib 32 extends beyond the bottom end face of the antenna 3. The end of the rib here extends beyond the bottom end face of the antenna 3 to ensure that the rib can be completely inserted into the bottom of the positioning groove 42.

[0035] The sleeve 4 includes a first sleeve portion 45 provided on the bottom shell 11, and a second sleeve portion 46 provided on the top cover 12. The engaging boss 41 is provided at one end of the first sleeve portion 45 and the second sleeve portion 46 away from the box body 1. The first sleeve portion 45 and the second sleeve portion 46 are both provided with a positioning groove 42. Since two positioning ribs 32 are provided in this embodiment, the first sleeve portion 45 and the second sleeve portion 46 are both provided with a positioning groove 42. The positioning groove 42 on the first sleeve portion 45 extends to a position close to the bottom of the first sleeve portion 45, and the positioning groove 42 on the second sleeve portion 46 extends to a position close to the bottom of the second sleeve portion 46, which is equivalent to the entire sleeve 4 being almost divided into four parts. Therefore, the sleeve 4 can have greater elastic deformation during the assembly process to avoid the difficulty of inserting the antenna 3.

[0036] The clamping portion 31 is provided with a first guiding inclined surface 33 , and the clamping boss is provided with a second guiding inclined surface 44 corresponding to the first guiding inclined surface 33 . The cooperation of the two inclined surfaces makes it easier to insert the antenna 3 .

[0037] During the assembly process, firstly, the spring 5 is sleeved onto the external socket 2, and then the positioning rib 32 of the antenna 3 is aligned with the interface of the positioning groove 42 and inserted until the first inclined surface and the second inclined surface are in contact, and then pressure is applied to deform the sleeve 4, and the clamping portion 31 is inserted into the sleeve 4 and buckled with the clamping machine boss. The antenna 3 is assembled.

[0038] The present invention also provides an auxiliary disassembly structure, which is used to assist in disassembling the antenna 3 of the above-mentioned antenna assembly structure with high safety, and is inserted into the sleeve 4 when in use. The auxiliary disassembly structure includes a base 6, a step portion 61 arranged on the upper end surface of the base 6, a plurality of opening portions 62 for opening the sleeve 4 evenly arranged on the upper end surface of the step portion 61, and a through hole 63 for the antenna 3 to pass through, and the through hole 63 passes through the base 6 and the step portion 61. The base 6 facilitates a person's finger to apply pressure to insert the auxiliary disassembly mechanism as a whole into the sleeve 4. When the antenna 3 passes through the through hole 63, the distance between the side of the opening portion 62 away from the central axis of the antenna 3 and the central axis of the antenna 3 is greater than the distance between the side of the clamping portion 31 away from the central axis of the antenna 3 and the central axis of the antenna 3, that is, it is ensured that after the opening portion 62 is inserted into the sleeve 4, the clamping boss 41 can be opened to the extent that the clamping portion 31 can be separated from the clamping boss 41 and come out of the sleeve 4. The interval between adjacent opening portions 62 corresponds to the size of the clamping portion 31.

[0039] There is a gap of 0.2 mm between the inner wall of the through hole 63 and the SAM connector end of the antenna 3 , that is, there is a gap of 0.2 mm between the outer walls at the maximum dimension of the antenna 3 , making it easier for the auxiliary disassembly and assembly structure as a whole to be put on the antenna 3 .

[0040] The stepped portion 61 is provided with slots 64 for connecting the positioning rib strips 32. The number of slots 64 is the same as that of the positioning rib strips 32, and there are also two. Therefore, the stepped portion 61 is also divided into two parts by the two slots 64, and the size of the slots 64 matches the limiting heads 34 of the positioning rib strips 32. Since the clamping portion 31 is divided into two parts by the two positioning rib strips 32, each part has four clamping portions 31, and the expanding portion 62 is inserted between adjacent clamping portions 31. Therefore, there are three expanding portions 62 provided on the stepped portion 61 of each part. A third guiding inclined surface 65 is provided at a position near the front end of the expanding portion 62. The third guiding inclined surface 65 can cooperate with the second guiding inclined surface 44 of the clamping boss to assist the auxiliary disassembly structure to be more easily inserted into the sleeve 4.

[0041] During specific use, the expanding portion 62 of the auxiliary disassembly structure is sleeved onto the antenna 3 towards the bottom end of the antenna 3 until the third stepped surface of the expanding portion contacts the second stepped surface of the clamping boss and expands the sleeve 4. After expansion, the clamping boss 41 is disengaged from the clamping portion 31, and the antenna 3 is ejected under the elastic force of the spring 5. After the antenna 3 is ejected, the clamping portion 31 contacts the upper end surface of the stepped portion 61 to prevent the antenna 3 from flying out.

[0042] The present invention also provides an electronic device, including the above-mentioned antenna assembly structure with high security.

[0043] In the present invention, a plurality of clamping portions are provided on the outer periphery of the antenna, and a clamping boss matching the clamping portion is provided on the inner side of the sleeve. The snap structure makes the assembly of the antenna more convenient and fast. At the same time, a spring is sleeved on the outer periphery of the external socket, eliminating the nuts and gaskets in the traditional structure, improving the assembly efficiency, reducing the cost, and the cooperation between the spring and the snap structure better limits the freedom degree of the antenna in the axial direction to avoid axial loosening. The fixed sleeve completely surrounds the external socket and the end portion of the antenna, ensuring the electrical safety performance. The cooperation between the positioning rib strip and the positioning groove facilitates the assembly, limits the insertion position and also limits the rotational freedom degree of the antenna. The present invention also provides an auxiliary disassembly and assembly structure for assisting in disassembling the antenna, making the disassembly process of the antenna convenient and fast, which is helpful for subsequent maintenance.
