1. Field of the Invention
The present invention relates to a power supply control device for an electronic product, and especially to a power supply control device which has an electronic element for power supply control and is provided independently of an electronic product, and which can independently be mounted, maintained and changed.
2. Description of the Prior Art
As to the technique of treating power supplying of conventional electronic equipment, after municipal electric power is input, according to electricity requirement of electronic products, mostly an electronic element for power supply control is used to conduct transforming or stabilizing voltage or alternate-direct current transforming etc., then an electronic product can be driven. The electronic element having conducted transforming or stabilizing voltage or alternate-direct current transforming always is integrated directly on an electric circuit board in the electronic product for the purpose of controlling the power supply.
Electronic products of nowadays get more and more precise during development, many electronic products having therein electronic elements for power supply control include control chips (or driving chips) which are in the types of IC, MCU etc. in practice, thereby we can see these control chips and the electronic elements for power supply control on electric circuit boards of many electronic products.
However, the control chips and the electronic elements for power supply control normally are the elements subject to being damaged, or to becoming inferior on their electric circuit boards of the electronic products; when the control chips and the electronic elements for power supply control are out of order or fail to pass the examination during leaving the factory, the whole electric circuit board examined shall be detached or changed, even the control chip on it shall be replanted, this results consumption of manpower, and makes higher cost of material.
For example, when an electronic product is an LED lamp, and the power supply controller (driving control IC) of it is damaged, a consumer is not able to change or repair by himself, it is a time and work wasting thing to sent the power supply controller back to the maintaining station for changing the driving control IC or the electronic elements for power supply control, and thereby is uneconomic.
Particularly if the power supply circuit and the power supply controller are still built in the product, once the LED lamp is out of order, the consumer and the manufacturer normally do not study in detail whether the electronic elements for power supply control is damaged, but just have the electric circuit board changed as a whole, or even discard the whole lamp set to waste resource.
In view of these, the inventor of the present invention designed a unique power supply control device for an electronic product, power supply controller of the power supply control device is designed to be a removable part, when the electronic product is out of order, a user can change the power supply controller by himself in order to repair the later in a mode which is faster; more convenient and cost lower, and can prolong the life of use of the electronic product.
The object of the present invention is to provide a power supply control device for an electronic product, an extremely important power supply controller on a power supply end of the electronic product can be provided independently, and the electronic product can be changed and removed/inserted through a simple and fast mounting means, this can reduce the cost of mounting and changing the power supply controller in production and maintenance, also the operation of mounting and changing can be faster and more convenient.
In order to achieve the above stated object, the power supply control device of the present invention includes a socket and a power supply controller; wherein the socket is provided on the electronic product, electricity runs between an electric circuit board and a power supply, and has a leading/insertion slot which is exposed on the electronic product; the power supply controller can be connected to the socket, at least includes a control chip for controlling the output electric power from the socket to the electronic product.
When in practicing, the power supply controller is in the shape of a sheet or any of other shapes that is benefit to easy insertion and extraction, one end (the insertion/extraction end) of it is provided with a plurality of electricity conducting pins; the leading/insertion slot is provided therein with a plurality of another set of electricity conducting pins in correspondence by position with the former electricity conducting pins for electrically connecting the two sets of pins, in order that the power supply controller can be designed in an independent mode, in a micro size and in a modularized mode.
And in practicing, the way of insertion/extraction of the power supply controller in relation to the leading/insertion slot (in addition to the way of using friction to have the power supply controller squeezed and positioned after insertion) can also have the leading/insertion slot designed to become an elastic push-push slot, in order to make the power supply controller be operated in an elastic push-push mode.
The followings are examples of application of the present invention:
The electronic product can be an LED lamp or an LED light emitting module of a lamp set, for instance: an LED lamp tube, an LED lamp bulb, a desk lamp, an embedded lamp, and an LED light emitting module of a road lamp etc.; in practicing, the control chip of the power supply controller can be an LED driver IC, the above mentioned socket is provided at an appropriate position on the LED lamp or the light emitting module, the electric circuit board of the lamp and the power supply are electrically connected with each other, and the leading/insertion slot is exposed to the outside; when the power supply controller which is relatively subjected to damaging is out of order, a user needs only to change the power supply controller via the leading/insertion slot directly, and the later can be fast repaired.
Similarly, the present invention can be used for a 3C electronic product such as a multimedia player, a TV etc.; so long that the socket is provided at an appropriate position on the electronic product to make exposition of the leading/insertion slot, power supply for the electronic product can be controlled through the power supply controller.
And the stated socket can also be provided on a battery module of the electronic product to make exposition of the leading/insertion slot of the socket; electric power can be put out to the electronic product by controlling the battery module of the power supply controller. This example is applicable to those portable devices having battery modules such as a notebook, a mobile phone, a portable display and a GPS navigation device etc., the range of applicability is very large.
As compared to the prior art, the present invention is advantageous in that: it makes the important power supply controller in the electronic element for power supply control be produced in an independent mode, in a micro size and in a modularized mode; this not only can increase the efficiency of production, but also can make fast changing when the power supply controller is damaged, in order to eliminate the problem that the electric circuit board in the electronic product must be detached during repairing, and to lower the cost and time for repairing.
The present invention will be apparent according to its technical means and after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
Referring firstly to
