Description

Diode holder assembly

The present invention relates to a diode holder assembly, and more particularly, to a diode holder assembly capable of installing a diode interchangeably.

In general, the mode of the electronic product is set by a function selection button installed on the front of the front panel or a remote controller, and the electronic product has a plurality of function selection buttons according to its purpose. It is mounted on the front of this front panel.

However, since the electronic product performs various modes by operating the function selection button, it is necessary to make the user recognize which function of the electronic product is being executed in order to improve the ease of use.

For example, electronic products such as a video cassette recorder and the like display and recognize a user's execution state of a mode such as power, play, eject, etc. by driving a display lamp. In the display lamp, a light emitting diode (LED) is mainly used.

On the other hand, the light emitting diode may constitute a pair of photo couplers with the light receiving diode, and the photo coupler receives an optical signal emitted by driving the light emitting diode by driving the light emitting diode to perform various detection functions. In addition, the light-emitting and light-receiving diodes are used as a carrier of the optical signal in the remote control.

As an example of such an electronic product, the video cassette recorder has a front panel Fp mounted on the front of the main chassis Mc, and a main circuit board Cm at the bottom of the main chassis Mc, as shown in FIG. 1. This horizontal installation, it is common that the front circuit board (Cf) is installed vertically on the rear surface of the front panel (Fp).

However, when the main and front circuit boards (Cm) (Cf) are separated into two, the so-called one type of electronic circuits using only the main circuit board (Cm) due to the increased assembly process and production cost of the product. Video cassette recorders of one type circuit boards have been developed. In a video cassette recorder of a one-type circuit board, a diode is provided in front of the upper surface of the main circuit board by a holder.

As shown in FIGS. 2A and 2B, a diode holder of a conventional electronic product has a pair of coupling holes H1 spaced apart from each other by a predetermined distance on an upper surface of a main circuit board Cm constituting an electronic circuit of the electronic product. A plurality of connection holes H2 are formed between the coupling holes H1 of the main circuit board Cm so that the leads L of the diodes D correspond to each other.

In addition, the holder 10 is assembled to the upper surface of the main circuit board (Cm), the holder 10 is fitted to the coupling holes (H1) of the main circuit board (Cm) on both sides of the body 11 to correspond to each other. Each pair of snap hooks 12 is formed.

On the other hand, the holder 10 has a plurality of storage spaces 14 that can accommodate the diode (D) by the plurality of partitions 13 on the upper surface of the body 11, the main circuit at the bottom of the storage spaces 14 A plurality of through holes 15 are formed to be located on the same line as the connection holes H2 of the substrate Cm, and a pair of hooks 16 fixing the diode D to the front of the storage spaces 14 are provided. Are formed respectively.

Therefore, in a state where the snap hooks 12 of the holder 10 are fitted into the coupling holes H1 of the main circuit board Cm to correspond to each other, the diodes D are placed in the storage spaces 14 of the holder 10. ) Is inserted vertically into the connection holes H2 of the main circuit board Cm through the through holes 15.

Then, when the diode D is rotated in a horizontal state from the vertical state to the front in the storage spaces 14 of the holder 10, the lead L of the diode D is deformed to the hooks 16. By this, the diode D is supported and mounted.

However, as described above, the holder 10 of the conventional holder 10 has a problem in that the installation posture of the diode D is changed while the lead L of the diode D accommodated in the storage spaces 14 is deformed.

For example, the diode D has a relatively easy installation posture in the up and down direction according to the deformation of the lead L, and thus the light of the diode D is not required to be reflected on the display window, for example, a gap in another place. There is a problem that the display function of the diode (D), such as leaking to the outside through the back is lost, causing assembly failure of the product.

In addition, since the holder 10 is manufactured to have only a structure for mounting the diode D to the main circuit board Cm, a separate holder must be manufactured to mount the diode D to the front circuit board Cf. There was.

As a result, not only increases the production cost, such as the need for a new mold for the manufacture of the holder 10, but also a problem that the development and production period of the electronic product is delayed. In particular, such a problem is raised as a larger problem when a variety of models of electronic products are produced.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention is to maintain the installation attitude of the diode accurately by a simple configuration and structure to prevent assembly failure of the product, the compatibility of the holder The present invention provides a diode holder assembly that can be easily made, which not only reduces the production cost of the product, but also greatly shortens the development and production period of the electronic product.

The supporter 20 has a plurality of bosses 23 formed on the upper surface of the body 21, and the bosses 23 are located on the same line as the support holes H1 of the main circuit board Cm. It has a guide hole 24 as much as possible.

In addition, the supporters 20 are formed on both sides of the upper surface of the body 21 so that the first and second arms 25 and 26 are substantially vertically separated by a predetermined distance, respectively, and the first and second arms 25 ( The shaft 27 is formed at the top of the 26. That is, the upper portions of the first and second arms 25 and 26 are connected to each other by the shaft 27.

The supporter 20 is formed such that a stopper 28 is gradually inclined on one of the first and second arms 25 and 26, for example, an upper portion of the inner surface of the first arm 25. That is, the stopper 28 of the supporter 20 is gradually inclined from the front to the rear to form a substantially triangular shape.

On the other hand, the holder 30 is mounted on the upper portion of the supporter 20 to be freely rotatable, the holder 30 is a plurality of holders so as to correspond to each other and the boss 23 of the supporter 20 on the upper surface of the body (31) The bosses 32 are formed, and the bosses 32 of the holder 30 have a receiving hole 33 so that the diode D can be accommodated.

In addition, the holder 30 is formed on both sides of the body 31, respectively, the fixing plate 34 is extended so as to correspond to each other between the first and second arms 25, 26. In the center of the fixing plate 34 is coupled to the shaft 27 of the first and second arms 25 and 26 so that the fitting groove 35 is rotatably opened to both sides by elastic deformation.
