Description

Front-pannel mounting apparatus for electronics product

The present invention relates to electrical / electronic products such as VCRs, DVDs, and set-top boxes, and more particularly, to a front panel mounting apparatus for mounting a front panel on a base chassis on which electrical equipment is mounted.

1 illustrates an example of the set-top box 100 of the electrical / electronic products.

In general, the set-top box 100 is a device for enabling digital broadcast reception in a general television receiver, and recently, has also performed a function of enabling the Internet to be used as a general television receiver.

As shown in FIG. 1, the set top box 100 includes a base chassis 110 on which electrical equipments (not shown) are mounted on an upper surface thereof, a front panel 120 coupled to the front of the base chassis 110, and It is coupled to the upper portion of the base chassis 110 includes a top cover 130 to form a space for receiving the electrical equipment therein. The front panel 120 is provided with a plurality of operation buttons 125 and a display panel 121 for operating the set top box 100.

The set top box 100 configured as described above was fixed to the front panel 120 with a fastener such as a screw (not shown) to the base chassis 110. However, this requires the use of a separate fastener such as a screw, there is a problem that the production efficiency is lowered because the process of tightening the screw is added in the assembly.

In order to solve this problem, recently, as shown in FIGS. 1 and 2B, a method using a mounting apparatus for elastically sliding coupling the front panel 120 and the base chassis 110 is mainly used.

The mounting device 140 includes a first coupling part 141 and a second coupling part 143, and each of the first and second coupling parts 141 and 143 correspond to each other in an elastic protrusion 145. And a mounting groove 147 is formed. Here, the elastic protrusion 145 is formed by cutting a portion of the first coupling portion 141 to bend inclined.

The mounting method of the front panel 120 by the mounting apparatus 140 configured as described above is as follows.

First, as shown in FIG. 2A, the front panel 120 is positioned in front of the base chassis 110. At this time, the first coupling part 141 and the second coupling part 143 are interviewed with each other. Thereafter, when the front panel 120 is pushed in the direction of the base chassis 110 as shown by the arrow shown in FIG. 2A, the first and second coupling parts 141 and 143 slide in an interview state. At this time, since the elastic protrusion 145 is in contact with the second coupling portion 143 from its base end, its shape is elastically deformed so that its end thereof is adjacent to the first coupling portion 141.

Thereafter, as shown in FIG. 2B, when the front panel 120 is completely mounted and the elastic protrusion 145 comes in a position facing the mounting groove 147, the front panel 120 returns to its original shape by its elastic restoring force. Thus, the elastic protrusion 145 is inserted into the mounting groove 147. In this case, the end surface of the elastic protrusion 145 may support the inner circumferential side of the mounting groove 147 to prevent the front panel 120 from being separated from the base chassis 110.

In the case of using the conventional mounting device 140 configured as described above, the elastic protrusion 145 and the mounting groove 147 may suppress the front panel 120 from flowing in the longitudinal direction of the set top box 100. However, when the external force acts in the horizontal direction X of the set-top box 100, the end of the elastic protrusion 145 may be separated from the contact surface of the mounting groove 147, thereby preventing the front panel 120 from being firmly fixed. There is a problem.

The present invention is devised to solve the above problems, and the object of the present invention is to provide a front panel mounting apparatus of an electric / electronic product whose structure is improved so as to solidify the combination of the front panel and the base chassis of the electric / electronic product. have.

It includes an elastic protrusion having a flow preventing piece formed by, when mounting the front panel Characterized in that the flow preventing members of the group which the elastic projection on one side of the mounting groove inserted between the first engagement portion.

According to this, even if the front panel flows in the longitudinal direction and the transverse direction of the set-top box by the external force in the state mounted to the base chassis, the coupling state can be maintained firmly.

According to a preferred embodiment of the present invention, when the mounting of the front panel is completed by engaging the second coupling portion to support the end surface of the flow preventing piece to suppress the movement of the elastic projection in the direction in which the front panel is separated It is preferred that the jaw be formed.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. On the other hand, in the description of the present invention for the components of the electrical / electronic products having the same configuration and function as the components of the conventional electrical / electronic products shown and described in Figures 1 to 2b above, the same reference numerals as in the prior art Reference is given and detailed description thereof is omitted.

Referring to FIG. 3, the mounting apparatus 240 of the set top box according to the embodiment of the present invention includes a first coupling part 241, a second coupling part 243, an elastic protrusion 245, and a mounting groove ( 247).

The first coupling part 241 protrudes from the base chassis 110 and is provided in a pair so as to correspond to both side surfaces of the base chassis 110 adjacent to the mounting portion with the front panel 120.

The second coupling portion 243 protrudes in pairs on both sides of the front panel 120 to be in surface contact with the first coupling portion 241 when the front panel 120 and the base chassis 110 are coupled to each other. Are installed to slide on each other. The mounting groove 247 is formed by cutting a portion of the second coupling portion 243 to form a through hole.

The elastic protrusion 245 is inclined downward in the direction in which the front panel 120 is mounted by cutting a part of the first coupling part 241 to be elastically inserted into the mounting groove 247 when the front panel 120 is mounted. By bending, the elastic piece 245a protruding from one side of the first coupling part 241 facing the second coupling part 243 and the end of the elastic piece 245a are formed when the front panel 120 is mounted. 1 includes a flow preventing piece 245b bent in parallel with the traveling direction of the coupling portion 241. According to this, a gap having a size that allows one side of the mounting groove 247 of the second coupling portion 243 to be inserted between the flow preventing piece 245b and the first coupling portion 241.

The coupling method of the front panel 120 and the base chassis 110 of the set-top box 100 configured as described above is as follows.

First, the front panel 120 is positioned in front of the base chassis 110 so that the first coupling portion 241 and the second coupling portion 243 are interviewed with each other. Thereafter, the front panel 120 is pushed toward the base chassis 110 so that the first coupling part 241 slides on the second coupling part 243 in the direction of the arrow A shown in FIG. 3. At this time, the elastic protrusion 245 of the first coupling portion 241 is elastically deformed into a shape in which the end thereof is close to the first coupling portion 241 by the second coupling portion 243.

When the front panel 120 slides in a direction toward the base chassis 110 to a predetermined position, the elastic protrusion 245 faces the mounting groove 247. At this time, the elastic protrusion 245 is released from the pressing force by the second coupling portion 243 to return to the original shape by its elastic restoring force between the flow preventing piece 245b and the first coupling portion 241. A gap of a predetermined size is formed in the. Subsequently, when the front panel 120 is slid and moved in the direction of the base chassis 110, as shown in FIG. 4, one side wall of the mounting groove 247 is a flow preventing piece 245b and the first coupling part 241. It is inserted in the gap between. At this time, one side edge of the mounting groove 247 inserted between the interval is supported by one side of the elastic projection 245 facing the first coupling portion 241. As a result, the flow of the second coupling part 243 in the direction in which the front panel 120 is separated is suppressed. In addition, the flow preventing piece 245b and the first coupling part 241 suppress the flow of the second coupling part 243 in the transverse direction X of the set top box 100 (see FIG. 1). As a result, the second coupling part 243 may be firmly fixed by suppressing the flow in both the longitudinal direction and the transverse direction of the set top box 100.

5 shows a mounting apparatus 240 according to another embodiment of the present invention. Referring to this, the mounting apparatus 240 according to the present embodiment is similar in configuration and function to most of the mounting apparatus 240 according to the previous embodiment, only, the first coupling portion 241 and the flow preventing piece 245b. ) Is different from the previous embodiment in that the locking step 247a prohibiting the front panel 120 from flowing in the direction in which the front panel 120 is separated protrudes from the second coupling part 243.

As shown, a part of one side wall of the mounting groove 247 performs the function of the locking step in this embodiment. This is possible because one side wall of the mounting groove 247 is formed stepped. According to this, when the front panel 120 is mounted, the end of the flow preventing piece 245b is supported by the engaging jaw 247a formed on a part of the inner wall of the mounting groove 247, and the first coupling part 243 is in contact with the first coupling part 243. The side surface of the opposing flow prevention piece 245b contacts and supports the support piece 247b protruded stepwise from the inner wall of the mounting groove 247. Accordingly, the front panel 120 can be more effectively suppressed from flowing in the horizontal direction X of the set top box 100, so that the front panel 120 and the base chassis 110 can be more firmly maintained. have.

On the other hand, the configuration of the locking step 247a is not necessarily limited only to this embodiment. Although not shown, various modifications can be made such that the end of the flow preventing piece 245b can be contacted and supported by the locking jaw formed to protrude from the second coupling portion 243. It is possible. The mounting groove 247 and the elastic protrusion 245 may be modified in various ways according to the installation positions of the first and second coupling parts 241 and 243.

In addition, although the present invention has been described as an example only in the case of a set-top box, the present invention is also applicable to other electrical / electronic products having a front panel and a base chassis coupled to each other, such as a VCR, DVD player, etc. Of course.

According to the present invention described as described above, by bending the end of the elastic projection again to further form a flow preventing piece, as both the longitudinal and transverse side surfaces of the second pressing portion are supported by the first coupling portion and the elastic projection, Even if the front panel flows in the longitudinal and transverse directions of the electrical / electronic product, the loosening of the coupling is suppressed.

Accordingly, there is an effect that the front panel can be firmly fixed to the base chassis simply without using a separate fastening component such as a screw.

As described above, the present invention has been illustrated and described with respect to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will appreciate that various changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
