Description

[0001] The present invention relates to a terminal assembly having a light source,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal assembly having a light source, and more particularly, to a terminal assembly having a light source that irradiates light to a front panel to increase the visibility of the terminal.

In recent years, as the supply of USB or multimedia cards (CF cards, SD cards, etc.) has become common, a multimedia terminal assembly for reproducing music files or moving picture files stored in these multimedia media is provided in the console or instrument panel of an automobile. The terminal assembly has a plurality of input ports, such as an external input terminal (AUX JACK) for connecting an external multimedia device, a card insertion portion for inserting a multimedia card, and a USB terminal for connecting a USB device to be.

The input port of such a terminal assembly needs to be made more visible for the user to easily recognize. This is because the interior of the vehicle is often dark and the input port of the terminal assembly is located at the bottom of the instrument panel.

For this purpose, a light source such as an LED lamp may be provided inside the terminal assembly to emit light around the input port of the terminal assembly. The LED lamp irradiates the light around the input port so that the user can easily recognize the input port. In this case, since it is difficult to uniformly emit light around a plurality of input ports by one LED lamp, a method of increasing the number of LED lamps is used.

Particularly, since a circuit board is provided inside the terminal assembly, a structure in which a plurality of LED lamps are arranged on the upper and lower surfaces of the circuit board in order to uniformly irradiate the light is applied in consideration of interference between the light source and the circuit board and various components do. However, extending the number of LED lamps in this way has the disadvantage of increasing the overall production cost of the terminal assembly.

In addition, a complicated reflective structure provided inside the terminal assembly guides the light emitted from each LED lamp toward the front panel. Such a reflective structure complicates the overall structure of the terminal assembly, It is difficult to manufacture.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to enhance the visibility of the terminal insertion portion by evenly irradiating the front panel with only a small number of light sources.

Another object of the present invention is to simplify the internal structure of the terminal assembly by reducing the reflective structure of the light source.

According to an aspect of the present invention for achieving the above object, the present invention provides a circuit board including a main housing having a mounting space formed therein, a circuit board inserted in a mounting space of the main housing in a horizontal direction and having at least one terminal portion, And a plurality of light source modules arranged on the top and bottom surfaces of the circuit board so as to stagger the light sources and irradiate light in at least one direction parallel to the direction in which the terminal units are installed; And a front cover which is coupled to a front surface of the main housing and shields the mounting space and forms a front panel having an opening of the terminal unit.

Wherein the light source module includes a pair of first light sources provided on one surface of the circuit board on which the terminal unit is mounted and a second light source provided on the opposite surface of the circuit board and disposed between the pair of first light sources, And the second light source irradiates light toward the front panel so as to be parallel to the longitudinal direction of the circuit board.

The reflective housing surrounds the remaining portion of the circuit board except for the front and back sides. The reflective portion is inclined at a position adjacent to the first light source of the light source module to reflect the light emitted from the first light source toward the terminal portion.

The inner edge of the reflective housing is curved.

And the reflective rib protrudes toward the upper surface of the circuit board at a position corresponding to the rear of the second light source.

The reflective housing is provided with guiding means on the inner surface of which the side of the circuit board is fitted and slidingly engaged. The reflective housing is inserted into the mounting space with the circuit board coupled to the inside of the reflective housing.

The front panel is formed by recessing a relatively thin light emitting portion around the edge of the inlet of the terminal portion.

An elastic support part is elastically deformable on an outer surface of the main housing, and an escape groove is formed on an outer surface of the reflective housing at a position corresponding to the elastic support part so that the elastic support part can be deformed

The terminal assembly having the light source according to the present invention as described above has the following effects.

In the present invention, a light source that directly irradiates light toward the front panel and a light source that indirectly irradiates light by using a reflector (reflective housing) are appropriately disposed on the circuit board. As a result, it is possible to increase the visibility of the insertion port formed on the front panel by irradiating the front panel evenly with a relatively small number of light sources, and as a result, the user's convenience and the quality of sensibility can be improved.

Further, in the present invention, since a light source for directly irradiating light toward the front panel is disposed on the side (the upper surface of the circuit board) where there is no component that interferes with the progress of light, the size of the reflector for light reflection can be reduced, . Therefore, the design of the terminal assembly is facilitated and the manufacturing cost is reduced.

In the present invention, since the inside of the reflector is curved as a whole, it is possible to collect light more effectively in the front panel direction, and the brightness of the edge of the insertion port can be made constant by irradiating the front panel more evenly.

The present invention relates to a terminal assembly having a light source. Here, the terminal may mean the input units 32 and 33 and the output units 34 and 35. The input units 32 and 33 are input ports, for example, an external input terminal (AUX JACK) for connecting an external audio device, a card insertion unit for inserting a multimedia card, a USB terminal for connecting a USB device . The light source illuminates these input ports to increase visibility. Hereinafter, a terminal assembly for a multimedia terminal assembly applied to an automobile will be described as an example.

As can be seen in Fig. 1, the terminal assembly according to the present invention has a substantially hexahedral shape. When the terminal assembly is installed in the vehicle, the portion exposed to the outside is the front panel 71 corresponding to the front surface, and the rest is embedded in the vehicle body and is not exposed. Therefore, it is important to increase the visibility by brightening the entrance edges of the front panel 71, particularly the terminal portions 32 and 33 located at the front. This is to allow the user to easily insert a multimedia device or the like. The structure will be described in detail below.

The main appearance and skeleton of the present invention are formed by the main housing 10. The main housing 10 is made of an insulating material and has a substantially hexahedral shape. The front and rear of the main housing 10 are open. This is because terminals must be exposed forward and backward. The front of the main housing 10 is shielded by the front cover 70. Inside the main housing 10, there is a mounting space 12 into which the circuit board 30 and the reflective housing 50, described below, are inserted.

The main housing 10 has a first fastening portion 13. The first fastening part 13 is provided on the outer surface of the main housing 10 so that the front cover 70 can be assembled. In this embodiment, the first fastening portions 13 are provided on both side surfaces of the main housing 10, and protrude in the form of projections. Here, the second fastening portion 77 of the front cover 70 is engaged. Of course, the shapes of the first fastening portion 13 and the second fastening portion 77 are not necessarily limited thereto. For example, the main housing 10 and the front cover 70 may be assembled by separate fasteners, or may be assembled together in various ways, such as a press-in structure or a fastener by an adhesive.

Referring to FIG. 2, the main housing 10 has an elastic support portion 15. The elastic supporting portion 15 is elastically deformable on the outer surface of the main housing 10. The resilient supporting portion 15 is in the form of a cantilever, and is elastically deformable to the inside of the main housing 10 through such a structure. When the terminal assembly according to the present invention is installed inside the vehicle, the elastic support portion 15 elastically supports the inside of the vehicle so that the terminal assembly can be firmly fixed. In the present embodiment, the elastic supporting portions 15 are provided on both side surfaces of the main housing 10, but only one side is shown in Fig.

A circuit board (30) is installed in the main housing (10). The circuit board 30 mounts the terminal portions 32 and 33 to transmit and control electric signals to the inside and the outside. The circuit board 30 is inserted into the main housing 10 in a horizontal direction with the printed circuit board 30. The circuit board 30 is not directly fitted to the main housing 10 but is first assembled with the reflective housing 50 to be described below and assembled with the reflective housing 50 into the main housing 10.

Referring to FIG. 6, when the circuit board 30 is inserted into the main housing 10, the mounting space 12 can be divided into an upper portion and a lower portion with the circuit board 30 as a center. The circuit board 30 is inserted in a direction parallel to the mounting space 12 but does not move along the upper or lower end but is located in the middle of the mounting space 12. [ Of course, the circuit board 30 may be installed to be offset to one side in the mounting space 12, which is close to the upper side of the mounting space 12 in FIG.

The circuit board 30 has a plurality of terminal portions 32 to 35. The terminal units 32 to 35 serve as various input and output ports. For example, the terminal units 32 to 35 include an external input terminal (AUX JACK) for connecting an external audio device, a card insertion unit for inserting the multimedia card, A USB terminal that can be connected, and the like. In this embodiment, there are four terminal portions 32 to 35 in total, and two (32, 33) are located in front of the circuit board 30 and the remaining two (34, 35) are located in the rear. The two front terminal portions 32 and 33 are respectively a USB terminal for connecting a USB device and an AUX terminal for connecting an audio device. The two rear terminals 34 and 35 are output terminals for transmitting an input signal to a processing device in the vehicle, and may also be configured as a USB terminal. Of course, the shape and the number of the terminal portions 34 and 35 are not necessarily limited thereto.

A plurality of pins (P) protrude from the upper surface (31) of the circuit board (30). The protruded pins P are provided on a component mounted on the bottom surface of the circuit board 30, and the pins P penetrate the circuit board 30 and a part thereof protrudes. In this embodiment, the pins P are provided in the terminal portions 32 to 35.

The circuit board 30 is provided with a light source module 40 (see FIG. 5). The light source module 40 irradiates light toward the front cover 70, more precisely, toward the front panel 71, thereby enhancing the visibility of the entrance of the front terminal portions 32 and 33. To this end, the light source module 40 is installed on the circuit board 30, receives power, and selectively irradiates the light by the control of the circuit board 30. In this embodiment, the light source module 40 is composed of an LED lamp, and a plurality of the light source modules 40 are installed on the circuit board 30. [

A plurality of light source modules 40 are arranged on the upper surface 31 and the lower surface of the circuit board 30 in a staggered manner. At least one of the plurality of light sources constituting the light source module 40 irradiates light forwardly, that is, in the direction of the front panel 71, in a direction in which the front terminal portions 32 and 33 are installed And irradiates light in a direction parallel to the direction of the light. That is, the light is irradiated in a direction parallel to the outer surface of the circuit board 30.

More precisely, the light source module 40 comprises a first light source 41 and a second light source 43, and the second light source 43 of the second light source 43 is arranged in parallel with the longitudinal direction of the circuit board 30, And irradiates light toward the panel 71. The first light source 41 is formed on one side of the circuit board 30 on which the terminal portions 32 and 33 are mounted and the second light source 43 is formed on the other side of the circuit board 30, And is disposed between the pair of first light sources 41. The irradiation angle of the second light source 43 is directed to the front panel 71 from the beginning.

On the other hand, the first light source 41 is irradiated in a direction perpendicular to the circuit board 30. This is because the terminal portions 32 and 33 are provided on the lower surface of the circuit board 30 to block the irradiation direction of the light. The light emitted from the first light source 41 is reflected by a reflecting plate of a reflective housing 50 to be described later and then is bent in the direction of the front panel 71 to brighten an entrance edge of the terminal portions 32 and 33. Such a structure will be described in detail below in the process of describing the reflective housing 50 below.

As shown in FIG. 5, the first light sources 41 are configured as a pair 41a and 41b, and the second light source 43 is disposed therebetween. Since the second light source 43 does not have the front terminal portions 32 and 33 which interfere with the irradiation of light in front, it is possible to effectively illuminate the front side of the terminal portions 32 and 33, . Since the second light source 43 is located between the pair of first light sources 41a and 41b in a wind-like manner, effective light irradiation is possible with only a relatively small number of light sources. 5, the second light source 43 is positioned between the pair of first light sources 41 and is located at one of the two first light sources 41, have. This may vary depending on the arrangement and size of the terminal portions 32 and 33.

The circuit board 30 is coupled to the reflective housing 50. The reflective housing 50 is inserted into the main housing 10 while being coupled to the circuit board 30. The reflective housing 50 reflects the light emitted from the light source module 40, (71). To this end, the reflective housing 50 has a structure to cover a direction of light from the light source module 40.

The reflective housing 50 is formed inside the reflective space 51 in the form of a tube, which is open front and rear and the remainder are connected to each other. Light irradiated from the light source module 40 is reflected at the reflective space 51, that is, the inner surface of the reflective housing 50. The reflective housing 50 may be made of a white plastic material such as polycarbonate (PC), polyphthalamide (PPA), or the like to enhance reflectivity. In such a case, the light scattering effect due to the inner surface of the reflecting housing 50 can be greatly improved, and the reflecting housing 50 can be manufactured at a relatively low cost. Alternatively, a reflection material such as a metal having a light reflecting property may be coated on the reflection surface, which is the inner surface of the reflection housing 50, by coating, plating or vapor deposition. In this embodiment, the reflective housing 50 is simply made of a white plastic material.

A reflective portion 55 is provided inside the reflective housing 50. The reflective portion 55 protrudes from the reflective space 51 of the reflective housing 50 and is inclined toward the front of the reflective housing 50, that is, toward the front panel 71. More precisely, the reflective portion 55 extends from the bottom of the reflective space 51 and extends obliquely toward the rear of the reflective housing 50 toward the upper side, thereby being inclined as a whole. The inclined reflecting portion 55 reflects the light of the first light source 41, which is irradiated in the direction perpendicular to the upper direction, toward the front panel 71. For this, the reflective portion 55 is inclined at a position adjacent to the first light source 41 of the light source module 40.

The inner edge 52 forming the reflective space 51 of the reflective housing 50 is curved. If the edge 52 of the reflective space 51 is formed to be orthogonal or sharp, light can not be smoothly reflected at the edge 52. Thus, in this embodiment, the edge 52 of the reflective space 51 is also curved . The four corners 52 forming the reflective space 51 may be all curved or partially curved.

The reflective space 51 has guide means 53. The guide means 53 protrudes from the inner surface of the reflective space 51 and extends in the assembly direction between the reflective housing 50 and the circuit board 30. The side surface of the circuit board (30) is inserted into the guide means (53) for sliding engagement. To this end, the guide means 53 has a structure in which the side surface of the circuit board 30 can be fitted. In this embodiment, the two ribs extend in parallel, and the side surface of the circuit board 30 can be sandwiched therebetween have. Preferably, the guide means 53 is provided symmetrically on both inner surfaces of the reflective space 51 for stable assembly.

Referring to FIG. 6, the reflective housing 50 has a partition rib 56. The partition rib 56 protrudes downward from the ceiling portion of the reflective space 51 of the reflective housing 50 and the reflective space 51 is divided into a front space and a rear space by the partition rib 56. The light emitted from the light source module 40 may be transmitted to the front panel 71 when the light is incident on the partition rib 56 because the partition rib 56 may reflect light. The partition ribs 56 also serve to reinforce the overall strength of the reflective housing 50.

The reflective housing 50 has an escape groove 58 formed on the outer surface thereof. The avoidance groove 58 is a portion of the outer circumference of the reflective housing 50. The avoidance groove 58 is a space for allowing the elastic support portion 15 of the main housing 10, . In the present embodiment, the avoidance grooves 58 are formed on both sides of the reflective housing 50, respectively.

A front cover 70 is coupled to the main housing 10 with the reflective housing 50 and the circuit board 30 interposed therebetween. The front cover 70 shields the front of the mounting space 12 of the main housing 10. The front panel 71 provided on the front cover 70 constitutes a front surface of the terminal assembly according to the present invention. When the terminal assembly is installed in the vehicle, the front panel 71 is actually seen.

The front panel 71 has insertion ports 72 and 75. The insertion ports 72 and 75 are formed at positions corresponding to the openings of the terminal portions 32 and 33. The user inserts the terminals of the earphone into the openings of the terminal portions 32 and 33 through the insertion ports 72 and 75 USB can be inserted. In this embodiment, the insertion ports 72 and 75 are composed of a first port for insertion of the AUX terminal and a second port for insertion of the USB. Of course, the number and shape of the insertion ports 72 and 75 may vary depending on the terminal portions 32 and 33.

At the edges of the insertion ports 72 and 75, light emitting portions 73 and 76 are provided. The light emitting portions 73 and 76 are formed to have a relatively thin thickness surrounding the entrance edge of the terminal portions 32 and 33. Since the light emitting portions 73 and 76 are thin, the light emitted from the light source module 40 can be more clearly seen. If the light emitting portions 73 and 76 are brightly illuminated, the user can easily recognize the positions of the insertion ports 72 and 75 even in a dark environment, and as a result, the visibility of the insertion ports 72 and 75 is increased.

The front cover 70 has a second fastening portion 77. The second fastening part 77 is engaged with the first fastening part 13 of the main housing 10 and is elastically deformable. When the first fastening part 13 is inserted into the fastening hole 78 formed in the second fastening part 77, the first fastening part 13 and the second fastening part 77 are engaged with each other, The front cover 70 is assembled. The second fastening portions 77 are provided on both sides of the front cover 70, respectively.

Hereinafter, the assembly and use of the terminal assembly having the light source according to the present invention will be described.

First, the reflective housing 50 is coupled to the circuit board 30 on which the light source module 40 is installed. Guide means 53 is provided on the inner side of the reflective space 51 of the reflective housing 50 so that both sides of the circuit board 30 can be guided by the guide means 53 and move inward. The reflective housing 50 and the guide means 53 are coupled to each other and the circuit board 30 can be fixed in the correct posture by the guide means 53 of the reflective housing 50. [

The circuit board 30 and the reflective housing 50 assembly are inserted into the mounting space 12 of the main housing 10. Since the mounting space 12 is opened frontward and rearward, the circuit board 30 and the reflective housing 50 can be inserted into the mounting space 12. In this embodiment, the circuit board 30 and the reflective housing 50 assembly are inserted in front of the mounting space 12.

When the circuit board 30 and the reflective housing 50 are inserted into the mounting space 12, the reflective housing 50 is positioned between the circuit board 30 and the inner surface of the mounting space 12. [ At this time, since the guide means 53 of the reflecting housing 50 fixes the circuit board 30, the circuit board 30 can have an accurate attitude in the mounting space 12. [ When the circuit board 30 is installed in the correct posture, the direction of the light emitted from the light source module 40 mounted on the circuit board 30 is also accurately set.

Finally, a front cover 70 is installed on the front surface of the main housing 10. The front cover 70 is assembled to the main housing 10 when the second fastening portion 77 of the front cover 70 is caught by the first fastening portion 13 of the main housing 10. [ In this embodiment, the first fastening portions 13 are provided on both sides of the main housing 10, and the second fastening portions 77 of the front cover 70 are engaged with the first fastening portions 13.

When the front cover 70 is coupled to the main housing 10, the front cover 70 forms the front surface of the terminal assembly and the front panel 71 of the front cover 70 is positioned in front of the terminal portions 32 and 33 do. Since the insertion ports 72 and 75 formed on the front panel 71 are formed at positions corresponding to the inlets of the terminal portions 32 and 33, the user can easily insert the terminal portions 32 and 33 through the insertion ports 72 and 75 You can plug in the earphone jack or USB at the entrance.

The terminal assembly thus assembled is installed inside the vehicle. The terminal portions 32 and 33 located at the rear in the installation process are connected to a power supply device or the like inside the automobile. Since the front panel 71 is exposed toward the occupant after the terminal assembly is installed inside the vehicle, the occupant can utilize the insertion ports 72 and 75.

Meanwhile, in the process of installing the terminal assembly on the vehicle, the elastic support portion 15 of the main housing 10 is elastically deformed so that the terminal assembly can be fixed firmly without any clearance or vibration. The resilient supporting portion 15 is in the form of a cantilever so that it can be elastically deformed to the inside of the main housing 10. When the terminal assembly according to the present invention is installed inside the vehicle, the elastic support portion 15 elastically supports the inside of the vehicle. The clearance space in which the elastic supporting portion 15 can be elastically deformed is provided by the avoidance groove 58 of the reflective housing 50 described above.

When power is supplied to the terminal assembly, light is irradiated from the light source module 40. When the light is irradiated from the light source module 40, the peripheries of the insertion ports 72 and 75 of the front panel 71 become brighter than the surrounding area, and the visibility of the insertion ports 72 and 75 is increased. First, the first light source 41 constituting the light source module 40 is irradiated with light in a downward direction, that is, in a direction perpendicular to the longitudinal direction of the circuit board 30, . The light irradiated by the first light source 41 is reflected on the inner surface of the reflecting housing 50 and then directed to the front panel 71. In this way, the first light source 41 is set so as to be reflected without directly irradiating light toward the front panel 71 in order to avoid interference with the terminal portions 32 and 33 described above.

6, the light emitted from the pair of first light sources 41 is reflected on the inner surface of the reflective housing 50 and then directed toward the front panel 71, more precisely in the reflective housing 50 And reflected by the reflection part 55. The reflector 55 is inclined so that the light of the first light source 41 is reflected forward. In addition, since the inner edge 52 of the reflective housing 50 is a curved surface, the light emitted from the first light source 41 together with the reflective portion 55 can be forwardly transmitted. Thus, more efficient light transmission is possible.

In this embodiment, the pair of first light sources 41 are disposed on the left and right sides, and are close to the two terminal portions 32 and 33 provided on the front side, respectively. Therefore, the light emitted from the first light source 41 is irradiated to the periphery of the two terminal portions 32 and 33. Of course, the light reflected by the reflective housing 50 can be directed in various directions, so that the pair of first light sources 41 do not independently irradiate light to the two terminal portions 32 and 33, respectively.

On the other hand, the second light source 43 constituting the light source module 40 irradiates light directly toward the front panel 71. The second light source 43 directly irradiates light toward the front panel 71 because there is no interference element such as the terminal portions 32 and 33 between the second light source 43 and the front panel 71. [ Since most of the light emitted by the second light source 43 is directly transmitted to the front panel 71 without reflection, it is unnecessary to consider the reflection angle or the reflection amount. Therefore, by arranging the light at the position corresponding to the middle of the two terminal portions 32 and 33 The periphery of the terminal portions 32 and 33 can be uniformly brightened.
