Description

Movable baffle assembly

This creation is about a baffle assembly applied to a computer host, especially a movable baffle assembly used to protect input and output interfaces.

In the prior art, in order to increase the convenience of assembly and improve the aesthetics of the computer host, the existing computer host gradually changes the I/O baffle on the back panel of the host chassis into an integrated unit directly connected to the circuit board I/O module. I/O baffle to avoid the problem that the opening of the I/O baffle attached to the main chassis does not match the port of the I/O module, and the integrated design of the baffle to strengthen the I/O The protective ability of the O module.

However, when the I/O baffle is changed to an integrated connection to the I/O module, the I/O baffle is mainly locked to the mainframe housing through the mainboard, and directly abuts and contacts the mainframe backplane. However, when the size of the mainboard is slightly different from the mainframe casing, it is easy to prevent the I/O baffle provided on the I/O module from contacting the backplane of the casing, causing the electrostatic discharge of the I/O module ( ESD) or electromagnetic induction (EMI) will not be able to be grounded to the chassis backplane through the I/O baffle, resulting in damage to the I/O module or electronic components on the circuit board. In addition, because the mainframe shell usually uses aluminum alloy for the shell outside the frame in order to take into account the light weight and the ability of heat dissipation, when the shell is impacted or squeezed, it is easy to produce slight deformation. When the phenomenon occurs on the backplane of the chassis, it will also make the integrated I/O baffle and the backplane of the chassis unable to contact reliably, which will lead to the aforementioned problem of poor grounding of the I/O module.

In view of the fact that in the prior art, the existing integrated I/O baffle is likely to be unable to effectively contact the machine due to the size of the motherboard and the chassis, or the deformation of the chassis backplane. The case backplane causes poor grounding of the I/O module; for this reason, the main purpose of this creation is to provide a movable baffle assembly that can have a slight tolerance between the I/O module and the case backplane , Or when the backplane of the chassis is slightly deformed, the I/O module can reliably contact the backplane of the chassis through the movable baffle assembly, so that the I/O module can effectively use the movable baffle The components are grounded to the chassis backplane.

The frame is integrally connected to the baffle body and has a grounding surface. A plurality of conductive bumps respectively protrude from the ground plane along the first direction and are used to electrically contact the opening. A plurality of limit screws pass through the limit holes from the outer side to be locked to the input and output interface module, and each limit screw has a limit part, and the limit part of the limit screw is used to snap into The limiting hole is used to enable the baffle body to be movably arranged between the limiting portion and the input and output interface module along the first direction.

The conductive elastic system is arranged between the baffle body and the input and output interface module, and abuts on the inner side and the end surface, and when the conductive elastic body is in an uncompressed state, there is a first distance between the conductive bump and the end surface When the circuit board is fixed to the side plate of the casing, the conductive elastic body is squeezed by the baffle body and the end surface to enter a squeezed state, and the distance between the conductive bump and the end surface is reduced from the first distance to the first Two distance.

In one of the subsidiary technical means derived from the above necessary technical means, the ground plane and the outer mask have a drop distance, and each conductive bump protrudes from the ground plane to a height along the first direction, and the height is smaller than the drop distance.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the conductive elastic body is provided with at least one port perforation, and at least one of the ports is respectively stuck through the port perforation and exposed to the port opening.

In one of the auxiliary technical means derived from the above-mentioned necessary technical means, each limit screw further includes a locking end and a sliding section. The locking end is arranged opposite to the limit part and is used to lock the input and output interface modules. The sliding section is located between the locking end and the limit part.

As mentioned above, the movable baffle assembly of this creation uses the limit screw to movably connect the baffle body to the input and output interface module, and then the conductive elastic body is arranged between the baffle body and the input and output interface. Therefore, when the circuit board assembly is fixed to the computer case, no matter whether the case backplane is farther from the input and output interface module than the preset position, the conductive bumps can contact the computer through the elastic support of the conductive elastomer. The shell backplane effectively grounds the input and output interface modules to the shell backplane.

In addition, the sliding section 42 does not have a thread, and is only used to limit the position of the limited hole 14 and limit the limit screw 4 to only reciprocate in the second direction D2, but in other embodiments it is not limited to this, even if the sliding section 42 has threads, as long as the sliding section 42 is not locked into the fixing hole 202111, for example, when the length of the locking end 41 and the sliding section 42 in the second direction D2 exceeds the screw depth of the fixing hole 202111, the sliding can also be made The segment 42 cannot be locked into the fixing hole 202111, and thus achieves the function of only restricting the reciprocating movement of the limit screw 4 in the second direction D2.

Please continue to refer to Figures 4 to 8. The fourth figure shows the three-dimensional exploded schematic diagram of the circuit board assembly with the movable baffle assembly of this creation and the computer case; the fifth figure shows the combination of this creation The three-dimensional schematic diagram of the circuit board assembly of the movable baffle assembly placed in the computer case; Figure 6 is a schematic plan view showing the circuit board assembly of the movable baffle assembly of this creation placed in the computer case; Figure 7 is an enlarged schematic view of circle A in Figure 6; Figure 8 is an enlarged schematic view showing that the circuit board assembly moves in the second direction to compress the conductive elastic body of the movable baffle assembly of the present invention.

As shown in Figures 1 to 8, when the movable baffle assembly 100 is assembled to the input/output interface module 202, it can be placed in a computer case 300 along with the circuit board assembly 200; among them, the computer The casing 300 includes a casing side plate 301 and a casing back plate 302, and the casing back plate 302 defines an opening 3021.

Moreover, in the fourth to seventh figures, the circuit board assembly 200 is only placed in the computer case 300 first. At this time, the conductive elastic body 5 is supported by the end face 20221 and pushes the baffle body 1 to the second direction D2. The fixing hole 202111 is clamped against the limiting portion 43, and the plurality of conductive bumps 3 provided on the grounding surface 21 will electrically contact the opening 3021. At this time, the conductive elastic body 5 is in an uncompressed state, and the conductive bumps 3 There is a first distance d1 from the end surface 20221.

At this time, since the conductive bump 3 has abutted the opening 3021, it will be located The conductive elastic body 5 between the baffle body 1 and the end surface 20221 is squeezed into a squeezed state, and the conductive bump 3 and the end surface 20221 are reduced from a first distance d1 to a second distance d2.

Wherein, no matter whether the conductive elastic body 5 is in the uncompressed state or the compressed state, the baffle body 1 will be supported by the conductive elastic body 5 so that the conductive bumps abut against the chassis back plate 302, which means the entire input and output interface module 202 can be grounded to the chassis backplane 302 through the conductive elastic body 5, the baffle body 1, the frame 2 and the conductive bumps 3. In addition, since the conductive elastic body 5 is already in a compressed state when the circuit board assembly 200 is assembled on the casing side plate 301, even if the casing back plate 302 is farther away from the input and output interface than the original position due to tolerances or deformation, etc. In the case of the module 202, the baffle body 1 can also be pushed against the baffle body 1 through the restoring elastic force of the conductive elastic body 5, so that the conductive bumps 3 are still in contact with the opening 3021 of the casing back plate 302.
