FIG. 1 is an exploded perspective view illustrating an overall configuration of a tuner module according to an embodiment of the present invention. FIG. 2 is a schematic plan view illustrating a general configuration of a tuner module according to an embodiment of the present invention. FIG. FIG. 2 is a side conceptual diagram illustrating the overall configuration of a tuner module according to an embodiment.

The present invention includes a chassis 100, a set main board 200, a circuit board 300, a first cover 400, a second cover 500, and a latching piece 310.

The chassis 100 has a total of four walls, which are open on both sides, to protect the circuit board 300 and various components to be described later from external impacts.

The chassis 100 can be manufactured by punching and bending a single metal plate to shorten unnecessary manufacturing processes such as soldering or welding and to minimize the locations where structural brittleness may occur in the vicinity of the joint, ) Can be increased.

The set main board 200 provides a space for supporting the chassis 100 through which the holes 202 for fixing the edges of the chassis 100 are fixed.

The circuit board 300 is embedded in the chassis 100 so as to be parallel to the set main board 200 and provides a space in which various components forming the circuit are seated.

The first cover 400 is closed from one side of the chassis 100 and the second cover 500 is closed from the other side of the chassis 100 to cover the circuit board 300 built in the chassis 100, From the impact of.

Here, the circuit board 300 is coupled or soldered along the edge of the hole 202 so that the latching piece 310 supporting the chassis 100 and the circuit board 300 is extended along the edge of the circuit board 300 And protrudes to the outside of the chassis 100.

The latching piece 310 may be bonded or soldered to the edge of the hole 202 as shown in the figure and a groove corresponding to the latching piece 310 may be formed along the edge of the hole 202, The circuit board 300 and the set main board 200 may be coupled together in such a manner that the groove and the locking piece 310 are fitted and fixed.

At this time, the chassis 100 is protruded by a part of the distance between the first cover 400 and the second cover 500 on the set main board 200, so that the chassis of the existing 11 mm type tuner module is also a 7 mm type You can use space like a slim chassis.

The present invention can be applied and practiced as described above, and for the description of other embodiments, the main components will be described below.

The chassis 100 includes a circuit board 300 and serves as an outer frame that is finished with the first cover 400 and the second cover 500. The chassis 100 includes the outer wall 110, the barrier rib 120, .

The outer wall 110 is wrapped along the edge of the circuit board 300 and the slit 112 through which the latching piece 310 protrudes.

The partition 120 separates a space formed by the outer wall 110 and prevents four walls constituting the outer wall 110 from being twisted and shields noises due to electromagnetic wave interference between various components mounted on the circuit board 300 It also plays a role.

The ground pin 130 is fixed to the ground hole 330 penetrating the circuit board 300. The ground pin 130 protrudes from the partition wall 120 to an open side of the outer wall 110. [

The chassis 100 includes a connecting piece 140 connecting the edge of the outer wall 110 and the partition 120 and a connector 150 mounted on the connecting piece 140 and electrically connected to the circuit board 300 .

The connecting piece 140 reinforces the structural strength of the connector 150 mounted on the chassis 100 and disperses and supports the load of an external cable (not shown) connected to the connector 150.

The connector 150 is connected to the external cable to receive signals from the external cable and serves as a relay for relaying signals processed from the components on the circuit board 300.

In the present invention, one connector 150 is shown as being mounted, but not limited thereto, a plurality of connectors 150 may be provided for selecting signals such as terrestrial broadcasts or cable broadcasts.

On the other hand, the distance between the first cover 400 and the second cover 500, that is, the width of the outer wall 110, is wide ranging from 7 mm, which is a slim shape, to 11 mm, which is a general shape, can do.

At this time, the distance d ₂ from the first cover 400 to the slit 112 is about 55% to 75% of the distance d ₁ between the first cover 400 and the second cover 500, As shown in FIG.

When the distance d ₂ is 55% or less of the distance d ₁ , the width of the outer wall 110 of the chassis 100 becomes too narrow. Therefore, due to the protruding component mounted on the circuit board 200, The second cover 500 can not be finished.

For reference, the first cover 400 is provided with the engaging piece 410 along the edge thereof so as to be engaged with the protrusion 140 protruding from the outer wall 110, and the second cover 500 can be closed by the same method The outer wall 110 can be closed.

When the distance d ₂ is 55% or less of d ₁ , heat generated from component parts mounted on the circuit board 200 is directly transmitted to the first cover 400 and the second cover 500, And the overheating of the entire circuit board 200, which may cause malfunction and breakage of the apparatus.

If the distance d ₂ is 75% or more of d ₁ , it is difficult to achieve the object of the slimming of the present invention.

Accordingly, the present invention is also applicable to a conventional tuner including a chassis having a thickness of 11 mm between the first cover and the second cover, such as a slim tuner having a thickness of 7 mm between the first cover and the second cover A whole slimization implementation becomes possible.

As described above, the present invention is based on the technical idea to provide a tuner module having an excellent durability while greatly reducing unnecessary work processes while improving the overall slimness and space utilization of the apparatus.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

Accordingly, the true scope of the present invention should be determined by the following claims.
