Description

Casing structure

Technical Field

The utility model relates to a shell structure.

Background

The common notebook computer case may be plastic case, metal case or alloy case, and compared with the metal case or alloy case, the plastic case has no conductivity, so that the notebook computer case has no electrostatic discharge and electromagnetic interference protection property. Thus, a conductive film, such as a metal film, is formed in the plastic housing by vacuum sputtering or the like.

Further, plastic housings are generally manufactured by injection molding, so burrs are easily formed on the parting surfaces. Taking a screw post (boss) in a plastic machine shell as an example, burrs are very easy to remain on the edge of the top surface of the screw post, and when the screw post is assembled, the burrs on the screw post are easy to collide and cause the conductive film coated on the burrs to be damaged, so that the electrostatic discharge and electromagnetic interference protection effect are affected.

Detailed Description

Fig. 1 is a schematic partial view of a housing structure according to an embodiment of the utility model. Fig. 2 is a partial schematic view of the chassis structure of fig. 1 with the conductive member removed. Fig. 3 is a schematic cross-sectional view of fig. 1 along section line A-A. Specifically, fig. 2 omits to illustrate the conductive film 120, so as to clearly show the structural design of the screw post 112. Referring to fig. 1 to 3, in the present embodiment, the housing structure 100 may be a housing of a host in a notebook computer, but is not limited thereto. In other embodiments, the chassis structure 100 may also be the housing of a server, a host of a desktop computer, a display, or other electronic device.

In an embodiment, the housing structure 100 includes a housing 110 and a conductive film 120, wherein the housing 110 may be a plastic housing, and the conductive film 120 may be a metal film formed in the housing 110 by vacuum sputtering or the like. Specifically, the casing 110 has an inner surface 111 and a screw stem 112 protruding from the inner surface 111, and the conductive film 120 covers the inner surface 111 and the screw stem 112 to prevent electromagnetic interference and prevent electrostatic discharge.

As shown in fig. 2 and 3, the screw column 112 has a top surface 112a, a sidewall surface 112b connecting the inner surface 111, and a recess 112c between the top surface 112a and the sidewall surface 112b, and the conductive film 120 covers the top surface 112a and the sidewall surface 112b. In addition, the recess 112c may be an annular recess located at an edge of the top surface 112a, and has a lateral surface 112d and an annular surface 112e. The lateral surface 112d connects the top surface 112a with the annular surface 112e, and the annular surface 112e connects the lateral surface 112d with the sidewall surface 112b. The conductive film 120 covers the lateral surface 112d and the annular surface 112e, and covers the burrs 113 on the annular surface 112e. That is, the burr 113 is located in the recess 112 c.

The annular surface 112e is lower than the top surface 112a, wherein the top surface 112a is spaced from the inner surface 111 by a first height H1 and the annular surface 112e is spaced from the inner surface 111 by a second height H2 that is less than the first height H1. In detail, the burr 113 is located at the junction between the annular surface 112e and the sidewall surface 112b, and protrudes away from the inner surface 111, but does not exceed the top surface 112a. Thus, the height H3 of the flash 113 above the annular surface 112e is less than the depth D of the recess 112c, and the height H3 of the flash 113 above the annular surface 112e is less than the difference between the top surface 112a and the annular surface 112e, which is substantially equal to the depth D of the recess 112 c.

Referring to fig. 1 and 3, in the present embodiment, the housing structure 100 further includes a conductive member 130 and a screw 140, wherein the conductive member 130 may be a hinge bracket, a circuit board or other conductive electronic component or non-electronic component, and the screw 140 passes through the screw post 112 and the conductive member 130 to lock the conductive member 130 on the housing 110. Further, the conductive member 130 abuts against the top surface 112a of the screw pillar 112, specifically contacts the conductive film 120 on the top surface 112a, and maintains a gap with the burr 113. Therefore, the conductive member 130 abutting against the screw post 112 will not collide with the burr 113, so as to avoid the conductive film 120 coated on the burr 113 from being damaged, so as to maintain the integrity of the conductive film 120, thereby improving the protection effect of electrostatic discharge and electromagnetic interference.

In summary, in the case structure of the present utility model, the screw has a retracted design, so as to prevent the conductive member abutting against the screw from colliding with the burrs on the screw, so as to maintain the integrity of the conductive film, thereby improving the protection effect of electrostatic discharge and electromagnetic interference.

Although the present utility model has been described with reference to the above embodiments, it should be understood that the utility model is not limited thereto, but rather may be modified or altered somewhat by persons skilled in the art without departing from the spirit and scope of the present utility model.
