[0004] However, the design of the connection assembly and chassis of the above-mentioned connector has the following problems:

[0005] Although the connection assembly and chassis of the above-mentioned connector are pre-guided by inserting the upper pre-guide part and the lower pre-guide part into the corresponding guide holes, thereby solving the technical problem of poor shielding effect, the upper pre-guide part and the lower pre-guide part will be corroded due to the long-term placement of the chassis in a harsh high-salt, high-humidity and easily corrosive environment, thereby affecting the shielding performance of the chassis.

[0017] In one embodiment, the fastener further comprises a washer, and the washer is arranged along the periphery of each through hole; and / or,

[0033] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0034] like Figures 1 to 2 As shown, a shielding chassis 10 of one embodiment includes a chassis body 100, a connector 200 and a conductive alloy gasket 300. The chassis body 100 is provided with a mounting hole 110. The connector 200 includes a connector body 210 and a fixing portion 220 extending outward from the outer peripheral side of the connector body 210. The connector body 210 is passed through the mounting hole 110. The chassis body 100 is provided with a locking and fixing area 120 adjacent to the mounting hole 110. One side of the conductive alloy gasket 300 abuts against the locking and fixing area 120, and the other side of the conductive alloy gasket 300 abuts against the fixing portion 220, so that the conductive alloy gasket 300 is fixed between the fixing portion 220 and the chassis body 100. The conductive alloy gasket 300 is sleeved on the connector body 210.

[0035] It can be understood that by opening a mounting hole 110 in the chassis body 100 and providing a locking and fixing area 120 near the mounting hole 110, and the connector 200 includes a connecting body and a fixing portion 220 extending outward, and because one side of the conductive alloy gasket 300 abuts against the locking and fixing area 120 and the other side of the conductive alloy gasket 300 abuts against the fixing portion 220, the connector 200 and the chassis body 100 are fitted on the conductive alloy gasket 300. At the same time, because the conductive alloy gasket 300 makes the connector 200 and the chassis body 100 have better conductivity, and because the conductive alloy gasket 300 fits the connector 200 and the chassis body 100, the connector 200 has better shielding properties in a humid and harsh environment.

[0036] It can be understood that compared with the prior art, the above-mentioned shielding chassis 10, because one side of the conductive alloy gasket 300 is in contact with the connector 200 and the other side of the conductive alloy gasket 300 is in contact with the chassis body 100, the conductive alloy gasket 300 can prevent the internal environment of the chassis body 100 from being corroded in a high-salt and humid environment, thereby improving the shielding properties of the shielding chassis 10 and helping to ensure the shielding performance of the shielding chassis 10 in complex environments.

[0037] Combine Figure 1 and Figure 2 As shown, in one embodiment, the conductive alloy gasket 300 is a copper alloy gasket or an aluminum alloy gasket. It is understood that because the copper alloy gasket and the aluminum alloy gasket have higher conductivity, the conductivity of the connector 200 and the chassis body 100 can be increased when the connector 200 and the chassis body 100 are attached to the conductive alloy gasket 300. In addition, the copper alloy gasket and the aluminum alloy gasket have relatively low density, which can shield electromagnetic waves, thereby improving the shielding performance of the connector 200 and the chassis body 100.

[0038] Combine Figure 1 and Figure 2 As shown, in one embodiment, the conductive alloy gasket 300 is a beryllium copper gasket. It is understood that by setting the conductive alloy gasket 300 to be a beryllium copper gasket, the beryllium copper gasket has good wear resistance and good corrosion resistance, ensuring that the connector 200 assembly 400 can maintain normal connection with the chassis body 100 in humid and harsh environments. At the same time, the beryllium copper material has excellent conductivity, which can improve the conductive continuity of the chassis and effectively solve the problem of high resistance.

[0039] Combine Figure 1 and Figure 2As shown, in one embodiment, the projections of the fixing portion 220 and the conductive alloy gasket 300 projected onto the chassis body 100 in the same direction overlap. It can be understood that the projection of the fixing portion 220 on the chassis body 100 is a first projection, and the projection of the conductive alloy gasket 300 on the chassis body 100 is a second projection. The first projection and the second projection overlap, so that the fixing portion 220 and the conductive alloy gasket 300 are completely fitted together and installed in the locking and fixing area 120 of the chassis body 100, which is conducive to maximizing the shielding performance of the connector 200 and the chassis and increasing the conductivity of the connector 200 and the chassis body 100.

[0040] Combine Figure 1 and Figure 2 As shown, in one embodiment, the conductive alloy gasket 300 defines a communication cavity 310; the connector body 210 is disposed through the communication cavity 310 and is electrically connected to the mounting hole 110. It will be understood that the communication cavity 310 is provided in the conductive alloy gasket 300, so that the connector body 210 is electrically connected to the mounting hole 110 of the chassis body 100 through the communication cavity 310, so that one end of the connector body 210 is connected to an external device, while the other end of the connector body 210 is connected to the chassis body 100.

[0041] Combine Figure 2 and Figure 3 As shown, in one embodiment, the connector 200 further includes a plurality of fasteners 230, a plurality of through holes 2210 are provided on the periphery of the fixing portion 220, and the chassis body 100 is provided with locking holes 130, and each fastener 230 is screwed into a corresponding locking hole 130 through a corresponding through hole 2210. It can be understood that by providing a plurality of through holes 2210 on the periphery of the fixing portion 220, the through holes 2210 are diagonally arranged at the corners of the fixing portion 220, and the chassis body 100 is provided with locking holes 130, and each fastener 230 is screwed into a locking hole 130 through the through hole 2210 in a one-to-one correspondence, the connector 200 is securely connected to the chassis.

[0042] Combine Figure 2 and Figure 3 As shown, specifically, each through hole 2210 is a waist-shaped hole. It can be understood that by designing each through hole 2210 as a waist-shaped hole, the oval shape of the waist-shaped hole allows the connector 200 to be securely mounted to the mounting hole 110 of the chassis while flexibly adjusting the fastener 230 to be fixed to the mounting hole 110. The waist-shaped hole design of the through hole 2210 provides more installation adjustment space, allowing for a larger position tolerance during installation, facilitating the alignment and adjustment of the fastener 230. Furthermore, when the positioning accuracy of the through hole 2210 is not particularly high, the waist-shaped hole structure allows the fastener to have a certain range of movement within the through hole 2210, reducing the position accuracy requirements.

[0043] Combine Figure 1 and Figure 2 As shown, in one embodiment, the conductive alloy gasket 300 is provided with a plurality of fixing holes 320, and each fastener 230 is sequentially threaded through the corresponding through hole 2210 and the corresponding fixing hole 320 to be screwed into the corresponding locking hole 130. It can be understood that the fixing holes 320 are provided on the conductive alloy gasket 300 so that the through hole 2210 and the fixing hole 320 coincide with each other, and the fastener 230 passes through the through hole 2210 and the fixing hole 320 on the conductive alloy gasket 300 and is screwed into the locking hole 130 of the chassis body 100, so that the conductive alloy gasket 300 is firmly attached to the fixing portion 220 of the connector 200, and the conductive alloy gasket 300 is installed on the mounting hole 110 of the chassis body 100.

[0044] like Figure 2 As shown, in one embodiment, the fastener 230 further includes a washer 2310, which is disposed along the periphery of each through hole 2210. It will be understood that the washer 2310 is disposed around the periphery of each through hole 2210, so that when the fastener 230 passes through the through hole 2210, it prevents the fastener 230 from slipping on the surface of the fixing portion 220 due to being too smooth, thereby avoiding the situation where the fastener 230 is difficult to be firmly locked in the through hole 2210 of the fixing member.

[0045] like Figure 2 As shown, in one embodiment, the locking and fixing area 120 is a groove structure. It can be understood that the locking and fixing area 120 is designed as a groove structure so that the conductive alloy gasket 300 can be placed in the locking and fixing area 120.

[0046] Combine Figure 3 and Figure 4As shown, in one embodiment, the connector body 210 includes a shell 2110, an insulating member 2120 and a plurality of conductive terminals 2130, the fixing portion 220 is protruded from the outer peripheral wall of the shell 2110, the shell 2110 is provided with a receiving hole 211a, the insulating member 2120 is formed in the receiving hole 211a, and the plurality of conductive terminals 2130 are located in the receiving hole 211a and are spaced apart on the insulating member 2120; one end of each conductive terminal 2130 extends to the end of the shell 2110 exposed outside the chassis body, and the other end of each conductive terminal 2130 extends to the end of the shell 2110 inside the chassis body. It can be understood that a receiving hole 211a is opened in the shell 2110, and an insulating member 2120 is formed and arranged in the receiving hole 211a, so that when the device is connected to the receiving hole 211a, the signal and current will be protected by the insulating member 2120, thereby protecting the connector 200 and the user's installation, preventing the current from flowing out of the connector 200, and a conductive terminal 2130 is set in the receiving hole 211a, one end of the conductive terminal 2130 extends to the outer end of the chassis body, and the other end extends to the end inside the chassis body, so that the external device is connected to the conductive terminal 2130 at the outer end of the chassis body, and the internal connecting line is connected to the conductive terminal 2130 inside the chassis body, so that the signal of the external device is transmitted to the conductive terminal 2130 inside the chassis body, so that the device inside the chassis body receives the signal transmitted from the outside.

[0047] Combine Figure 3 and Figure 4 As shown, in one embodiment, the housing 2110 and the fixing portion 220 are integrally formed. It can be understood that the housing 2110 and the fixing portion 220 are integrally formed, making the connector body 210 more robust and able to withstand harsh and impactful environments without structural damage.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1) By opening a mounting hole 110 in the chassis body 100, and providing a locking and fixing area 120 in the mounting hole 110, the connector 200 includes a connecting body and a fixing portion 220 extending outward. Because one side of the conductive alloy gasket 300 abuts against the locking and fixing area 120, and the other side of the conductive alloy gasket 300 abuts against the fixing portion 220, the connector 200 and the chassis body 100 are adhered to the conductive alloy gasket 300. At the same time, because the material of the conductive alloy gasket 300 makes the connector 200 and the chassis body 100 have better conductivity, and because the conductive alloy gasket 300 fits the connector 200 and the chassis body 100, the connector 200 has better shielding performance in a humid and harsh environment.

[0050] 2) Compared with the prior art, the above-mentioned shielded chassis 10 has one side of the conductive alloy gasket 300 in contact with the connector 200 and the other side of the conductive alloy gasket 300 in contact with the chassis body 100, so that the conductive alloy gasket 300 can prevent the internal environment of the chassis body 100 from being corroded in a high-salt and humid environment, thereby improving the shielding performance of the chassis and helping to ensure the shielding performance of the chassis in complex environments.

[0051] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
