Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.

Example one

The utility model provides an electronic components structure convenient to installation, includes first electronic components and second electronic components, first electronic components have two electrodes and draw the pin respectively by two electrodes, and second electronic components includes first end and second end. One end of the second electronic component is connected to one electrode of the first electronic component or one pin of the first electronic component, so that the second electronic component is electrically connected to the first electronic component, and meanwhile, the first electronic component and the second electronic component can be fixed to the PCB board 1 only by fixing the first electronic component to the PCB board 1, so that one through hole 11 is drilled in the PCB board 1 less, a plug-in process of the second electronic component is omitted, a soldering process when the second electronic component is fixed to the PCB board 1 in the traditional installation is omitted, the production period is effectively shortened, required soldering tin consumption is saved, the installation cost of the whole electronic component structure is reduced again, the market competitiveness of the electronic components is greatly improved, and considerable economic benefits are provided for the production party.

Referring to fig. 3 to 5, in this embodiment, the first electronic component is a varistor 4 (two leads for distinguishing the varistor are soldered on electrodes on different surfaces, one lead is shown by a dotted line and the other lead is shown by a solid line at a lead portion inside the encapsulation layer), the second electronic component is an input power line 2, and the input power line 2 is connected to any pin of the varistor 4, so that the input power line 2 is connected to the varistor 4, thereby reducing installation and drilling of the input power line 2, saving plug-in operation of the input power line 2, saving a soldering process of the input power line 2, and saving the amount of soldering tin by soldering one solder point 5. The input power line 2 and the pin of the varistor 4 can be fixedly connected by electric welding, and certainly, can also be fixedly connected by other welding methods, which is only for illustration and is not limited in this embodiment.

Any pin of the varistor 4 described in this embodiment may be any one of the first pin 41 and the second pin 42 of the conventional varistor 4, as shown in fig. 3. It can be understood that the electric welding points 6 formed by connecting the input power line 2 and the pins of the piezoresistors 4 are close to the encapsulating layer 45, in other words, the distance from the electric welding points 6 to the encapsulating layer 45 is less than the distance from the electric welding points 6 to the pins away from one end of the encapsulating layer 45, the distance from the electric welding points 6 to the pins away from one end of the encapsulating layer 45 is far enough, the pins can conveniently penetrate through the PCB 1 to be welded and fixed with the PCB 1, and the cost of electric welding is far lower than the soldering cost because no additional materials are needed.

It can be seen that, the input power line 2 is welded on any pin of the piezoresistor 4, so that the operation is very convenient, and the combination and transformation of the existing metal wire and the existing piezoresistor 4 into a more convenient new structure are facilitated. Namely, the welding action of welding the input power line 2 to the pin of the piezoresistor 4 is added, so that the beneficial effects of saving the drilling of the PCB (printed circuit board) 1, saving the plug-in action of the input power line 2, saving the soldering process of the input power line 2, saving the soldering tin amount by welding one soldering tin point 5 less, saving the space of the PCB 1 and the like are achieved.

Any pin of the varistor 4 described in this embodiment may also be any pin formed in the conventional varistor 4, when one of the first pin 41 and the second pin 42 is connected to an electrode, two ends of the pin extend out of the encapsulation layer 45 of the varistor 4, so that the varistor 4 has three pins, in other words, the third pin 43 is integrated with the first pin 41 or the second pin 42, as shown in fig. 4.

It should be noted that, in the conventional installation manner, the input power line 2 needs to be separately plugged in, in order to prevent the input power line 2 from falling from the through hole 11 of the PCB board 1, the general input power line 2 is formed by wrapping an insulating sheath 21 outside a metal wire core, and the insulating sheath 21 limits the metal wire core, as shown in fig. 1, or other limiting structures are arranged on the metal wire core. And the input power cord 2 of this embodiment need not to insert the through-hole 11 of PCB board 1, and then need not to set up limit structure, therefore the input power cord 2 of this embodiment can be the metal sinle silk.

For utilizing the spacing scheme of insulating skin 21, save the manufacturing procedure of the power cord of ordinary wire processing banding insulating skin 21, saved insulating skin 21's raw materials cost, also avoided ordinary power cord to suffer corresponding damage because of cutting insulating skin 21 process, and then influence the reliability of power cord. For the scheme of folding the metal wire into an integral body out of the limiting structure, the embodiment avoids the metal wire from being flattened and crushed, thereby ensuring the conductivity of the input power line 2. Compared with the scheme of additionally arranging the limiting structure outside the metal wire, the time and material cost for additionally manufacturing the limiting structure are saved.

Example two

Referring to fig. 6 and 7, the principle of the present embodiment is the same as that of the first embodiment, except that the connection manner of the input power line 2 and the varistor 4 is different, and one end of the input power line 2 of the present embodiment is integrated on any electrode (not shown) of the varistor 4, that is, one end of the input power line 2 is soldered to any electrode of the varistor 4, and then is packaged by the encapsulating layer 45, so that the first pin 41, the second pin 42, and the other end of the input power line 2 are exposed.

In this embodiment, the first pin 41 and the second pin 42 of the varistor 4 and the input power line 2 may be separately welded to the electrodes of the varistor 4, as shown in fig. 6. Alternatively, the lead wires forming the first lead 41 or the second lead 42 may be integrally formed and then soldered to the electrodes, and both ends of the lead wires are exposed out of the encapsulating layer 45, so as to form one lead of the varistor 4 and the input power line 2 after encapsulation, as shown in fig. 7. The electronic component structure of the embodiment not only has the beneficial effects of the first embodiment, but also reduces the processes of the pin electric welding of the input power line 2 and the piezoresistor 4, thereby saving time and cost.

EXAMPLE III

Referring to fig. 8 to 10, the principle of the present embodiment is the same as that of the first embodiment, the first electronic component is a voltage dependent resistor 4, and one end of the second component is electrically connected to the pin of the voltage dependent resistor 4, except that the second electronic component is a safety resistor 3.

Similarly, the safety resistor 3 has no difference between positive and negative electrodes, and any end of the safety resistor 3 is electrically connected to the first pin 41 or the second pin 42 of the conventional varistor 4, as shown in fig. 8, or any end of the safety resistor 3 is electrically connected to the third pin 43 of the varistor 4, and the forming manner of the third pin 43 is the same as that of the embodiment, as shown in fig. 9. The varistor 4 in this embodiment is fixed on the PCB board 1, that is, the safety resistor 3 is fixed on the PCB board 1 at the same time, as shown in fig. 10.

It should be noted that, in the traditional mounting manner, the safety resistor 3 needs to be plugged in separately, and after preventing the safety resistor from being plugged in, the end surface of the body is partially tightly attached to the PCB board 1, so that the safety resistor 3 cannot be bent towards the surface of the PCB board, and the length direction of the body of the safety resistor 3 cannot be parallel to the surface of the PCB board, thereby affecting the mounting connection between the pin of the safety resistor 3 far away from the PCB board 1 and the lamp cap, and therefore the safety resistor 3 often covers the heat-shrinkable sleeve 31, as shown in fig. 1. The safety resistor 3 of the present embodiment does not need to be inserted into a through hole (not labeled) of the PCB 1, so the safety resistor 3 of the present embodiment does not need to be coated with the heat shrinkable sleeve 31, and the material cost of the heat shrinkable sleeve 31 and the processing cost of the coated heat shrinkable sleeve 31 are saved.

Example four

Referring to fig. 11 and 12, the principle of the present embodiment is the same as that of the present embodiment, the first electronic component is the varistor 4, and one end of the second electronic component is electrically connected to the electrode of the varistor 4, but the second electronic component is the safety resistor 3. After one end of the safety resistor 3 is soldered to any electrode of the varistor 4, the first lead 41, the second lead 42, the safety resistor 3 and the other end thereof are exposed by packaging through the encapsulating layer 45.

The two lead wires forming the first lead 41 and the second lead 42 and the end of the fuse resistor 3 are separately welded to the electrodes of the varistor 4, as shown in fig. 11. Or the lead wire at one end of the safety resistor 3 is bent and molded and then welded on the electrode of the piezoresistor 4, the safety resistor 3 and the lead wire at the other end thereof are exposed out of the encapsulating layer 45, and one pin of the piezoresistor 4 and the safety resistor 3 are formed after encapsulation, as shown in fig. 12.

EXAMPLE five

Referring to fig. 13, there is another circuit principle at the power supply access end of the driving circuit of the led lamp, that is, an electrodeless capacitor 7 is connected in parallel between one end of the safety resistor 3 away from the ac input end and the other ac input end, and the electrodeless capacitor 7 is directly connected to the safety resistor 3 or the input power line 2, and the difference from the first to fourth embodiments is that the first electronic component is the electrodeless capacitor 7.

Referring to fig. 14 to 17, the first electronic component is the electrodeless capacitor 7, the second electronic component is the input power line 2, and the input power line 2 is connected to any pin of the electrodeless capacitor 7 or any electrode of the electrodeless capacitor 7, so that the input power line 2 is connected to the electrodeless capacitor 7. The electrodeless capacitor 7 is fixed with the PCB 1 through the soldering tin points 5, namely the input power line 2 is also fixed on the PCB 1, so that the installation and drilling of the power line are reduced, the plug-in action of the power line is saved, the soldering process of the power line is saved, and the soldering tin amount is saved by soldering one soldering tin point 5 less. Similarly, the input power line 2 in this embodiment may also be a metal wire core, so as to achieve the effects of saving time and cost.

The input power line 2 can be electrically welded to one lead of the conventional electrodeless capacitor 7, as shown in fig. 14. A third pin 73 is led out from any electrode of the electrodeless capacitor 7, and the input power line 2 is electrically welded on the third pin 73, as shown in fig. 15. Alternatively, the other end of the pin line of the first pin 71 or the second pin 72 forming the electrodeless capacitor 7 extends out of the encapsulation layer 75 to form the input power line 2, as shown in fig. 16. Certainly, the input power line 2 and the electrodeless capacitor 7 may have other connection modes, and when the first electronic component is the voltage dependent resistor 4, the connection mode of the input power line 2 is referred to, the principle is the same, and the description is not exhaustive.

When the electronic component structure of this embodiment is connected to the PCB 1, only the first lead 71 and the second lead 72 of the electrodeless capacitor 7 need to be fixed on the PCB 1 through the solder points 5, as shown in fig. 17.

EXAMPLE six

Referring to fig. 18 to 20, in the present embodiment, the first electronic component is the electrodeless capacitor 7, and the difference from the fifth embodiment is that the second electronic component is the safety resistor 3, and the safety resistor 3 is connected to any pin of the electrodeless capacitor 7 or to any electrode of the electrodeless capacitor 7, so that the safety resistor 3 is connected to the electrodeless capacitor 7.

The safety resistor 3 can be electrically welded on one pin of the conventional electrodeless capacitor 7, as shown in fig. 18. It can also be understood that the pin at one end of the safety resistor 3 is soldered on the electrode of the electrodeless capacitor 7 and extends out of the encapsulation layer 75 to form one pin of the first electrodeless capacitor 7, as shown in fig. 19, and the safety resistor 3 is exposed out of the encapsulation layer 75. Certainly, the safety resistor 3 and the electrodeless capacitor 7 may have other connection modes, and when the first component is the piezoresistor 4, the connection mode of the safety resistor 3 is referred to, the principle is the same, and details are not described herein.

When the electronic component structure of this embodiment is connected to the PCB 1, the electrodeless capacitor 7 and the safety resistor 3 can be fixed to the PCB 1 at the same time only by fixing the first lead 71 and the second lead 72 of the electrodeless capacitor 7 to the PCB 1 through the solder points 5, as shown in fig. 20.

EXAMPLE seven

An electronic component structure convenient to install comprises a first electronic component, a second electronic component and a third electronic component. The first electronic component is provided with two electrodes, and pins are respectively led out of the two electrodes, the second electronic component comprises a first end and a second end, and the third electronic component comprises a first end and a second end.

One end of the second electronic component is connected to one electrode of the first electronic component or one pin of the first electronic component, and one end of the third electronic component is connected to the other electrode of the first electronic component or the other pin of the first electronic component, so that the second electronic component and the third electronic component are electrically connected to the first electronic component, and meanwhile, the first electronic component, the second electronic component and the third electronic component can be fixed to the PCB board 1 simultaneously only by fixing the first electronic component to the PCB board 1.

Therefore, the PCB (printed circuit board) 1 is provided with less through holes 11, the process of inserting the second electronic component and the third electronic component is omitted, the process of soldering when the second electronic component and the third electronic component are fixed with the PCB 1 in the traditional installation is omitted, and the production period is effectively shortened. Meanwhile, the soldering tin amount required when the second electronic component and the third electronic component in the traditional installation are fixed with the PCB 1 is saved, so that the installation cost of the whole electronic component structure is reduced again, the market competitiveness of the electronic components is greatly improved, and considerable economic benefits are provided for a producer.

Referring to fig. 21 to 23 in combination with fig. 2, in the present embodiment, the first electronic component is the voltage dependent resistor 4, the second electronic component is the input power line 2, and the third electronic component is the safety resistor 3.

The input power line 2 is electrically connected to a first pin 41 of the varistor 4, and the safety resistor 3 is electrically connected to a second pin 42 of the varistor 4, as shown in fig. 21. Two ends of the two lead wires forming the first lead 41 and the second lead 42 extend out of the encapsulation layer 45 of the varistor 4, so that the varistor 4 has a third lead 43 and a fourth lead 44, and the input power line 2 and the safety resistor 3 are respectively soldered to the third lead 43 and the fourth lead 44, as shown in fig. 22.

It is understood that there are other connection modes for connecting the input power line 2 and the safety resistor 3 to the varistor 4, for example, the input power line 2 is connected to the electrode of the varistor 4, and the safety resistor 3 is soldered to the third pin 43; for example, the metal wire is bent and then welded to the electrode of the varistor 4, and two ends of the metal wire extend out of the encapsulation layer 45 to form the input power line 2 and the first pin 41, and one end of the safety resistor 3 is welded to the other electrode and extends out of the encapsulation layer 45 to form the second pin 42, and so on.

The way in which the input power line 2 and the safety resistor 3 are connected to the voltage dependent resistor 4 at the same time can refer to the combination of two of the first embodiment or the second embodiment and the third embodiment or the fourth embodiment, which is not exhaustive here.

When the electronic component structure of the present embodiment is mounted on the PCB 1, the first pin 41 and the second pin 42 of the varistor 4 are fixed on the PCB 1 through the soldering points 5, that is, the power input line 2 and the safety resistor 3 are fixed on the PCB 1 at the same time, as shown in fig. 23.

In another example of the mounting, the voltage dependent resistor, the input power line and the safety resistor are mounted on the aluminum substrate, the input power line and the safety resistor need to pass through the through hole of the aluminum substrate and then be fixed by a terminal (generally a metal terminal), and in order to prevent conduction with the wall of the through hole of the aluminum substrate and conduction between the input power line and the safety resistor, the input power line and the safety resistor are usually covered by an insulating coating. The structure in the embodiment is arranged on the aluminum substrate, the input power line and the safety resistor only need to be prevented from being conducted with each other without penetrating through a through hole of the aluminum substrate, and therefore any insulating skin is coated between the input power line and the safety resistor, so that the insulating skin is saved, and a plug-in process is reduced.

Example eight

Referring to fig. 24 to 26 and with reference to fig. 13, the principle of the present embodiment is the same as that of the seventh embodiment, the second electronic component is the input power line 2, and the third electronic component is the safety resistor 3, except that the first electronic component of the present embodiment is the electrodeless capacitor 7. The input power line 2 and the safety resistor 3 are simultaneously connected to the electrodeless capacitor 7, so that the electronic component structure and the PCB 1 can be conveniently installed.

The input power line 2 is electrically connected to a first lead 71 of the electrodeless capacitor 7, and the safety resistor 3 is electrically connected to a second lead 72 of the electrodeless capacitor 7, as shown in fig. 24. Two ends of two lead wires forming the first lead 71 and the second lead 72 extend out of the encapsulation layer 75 of the electrodeless capacitor 7, so that the electrodeless capacitor 7 has a third lead 73 and a fourth lead 74, and the input power line 2 and the safety resistor 3 are respectively soldered to the third lead 73 and the fourth lead 74, as shown in fig. 25.

It can be understood that there are other connection modes for connecting the input power line 2 and the safety resistor 3 to the electrodeless capacitor 7 at the same time, for example, the input power line 2 is connected to the electrode of the electrodeless capacitor 7, and the safety resistor 3 is soldered to the third pin 73; for another example, the metal wire is welded on the electrode of the electrodeless capacitor 7, and two ends of the metal wire extend out of the encapsulation layer 75 to form the input power line 2 and the first pin 71, and one end of the safety resistor 3 is welded on the other electrode and extends out of the encapsulation layer 75 to form the second pin 72, and so on.

Referring to fig. 27, there is another circuit principle at the power input end of the driving circuit of the led lamp, a bridge stack 8 is connected between one end of the safety resistor 3 away from the power input end and the other power input end, that is, the safety resistor 3 or the input power line 2 is directly connected to the bridge stack 8, and further, the difference from the seventh embodiment or the eighth embodiment is that the first electronic component is the bridge stack 8.

Referring to fig. 28, the bridge stack 8 has four pins, which are an ac input 81, an ac input 82, a dc output 83 and a dc output 84. In this embodiment, the input power line 2 is electrically connected to the ac input terminal 82 of the bridge stack 8, and the safety resistor 3 is electrically connected to the ac input terminal 81 of the bridge stack 8. Two direct current output pins of the bridge rectifier 8 are fixed on the PCB board 1 through the soldering points 5, so that the safety resistor 3 and the input power line 2 can be fixed on the PCB board 1, the PCB board 1 is provided with one less chip mounting process, 4 chip mounting pads are arranged less, one plug-in process is omitted, and the production period is effectively shortened. Meanwhile, the soldering tin amount required when the bridge rectifier 8 is fixed with the PCB 1 is saved, so that the installation cost of the whole electronic component structure is reduced again, the market competitiveness of the electronic component is greatly improved, and considerable economic benefits are provided for a producer.

In another example of mounting, the input power line 2 and the safety resistor 3 are mounted on an aluminum substrate, the input power line and the safety resistor need to be fixed by a terminal (generally a metal terminal) after passing through a through hole in the aluminum substrate, and in order to prevent conduction with a hole wall of the through hole in the aluminum substrate and conduction between the input power line and the safety resistor, the input power line 2 and the safety resistor 3 are usually coated with an insulating material. The structure in the embodiment is arranged on the aluminum substrate, the input power line and the safety resistor only need to be prevented from being conducted with each other without penetrating through a through hole of the aluminum substrate, and therefore any insulating material is coated between the input power line and the safety resistor, so that the insulating material is saved, and a plug-in process is reduced. In addition, the original patch bridge stack is changed into a plug-in bridge stack, so that the aluminum substrate has one less patch process, 4 patch bonding pads are arranged less, and the production period is effectively shortened. Meanwhile, the soldering tin consumption required when the bridge rectifier 8 is fixed with the aluminum substrate is saved, so that the installation cost of the whole electronic component structure is reduced again.

Referring to fig. 30, the lamp further comprises a PCB board 1 (since the PCB board is located inside the heat sink, the PCB board is also shown in dashed lines in fig. 30 and only part of the dimensions of the driver board are taken). In this embodiment, the PCB board 1 may be a single-sided board or a double-sided board, where the PCB board 1 includes the electronic component structure described in any one of the first to ninth embodiments, and the input power line 2 is on the PCB board 1.

The lamp further comprises a lamp cap 130, as shown in fig. 31, wherein the head of the heat sink 110 and the PCB board 1 inside the heat sink are both encapsulated by the lamp cap 130. When the lamp cap 130 and the heat sink 110 are assembled and fixed together, one end 2b of the input power line 2 far away from the PCB board 1 is in direct contact with the conductive sidewall of the lamp cap 130 for electrical connection.

Of course the lamp may also be of another type, for example an all glass type lamp, in particular an LED filament lamp. In this lamp type, the end 2b of the input power line 2 away from the PCB is also connected to the lamp cap.

Because the lamp of this embodiment includes corresponding electronic components structure, therefore the lamp can have the corresponding beneficial effect of each aforementioned embodiment.
