Technical Field
The utility model relates to the technical field of lighting equipment manufacturing, in particular to a circuit board, a power box with the circuit board and a lamp with the circuit board.
Background
The circuit board of the LED lighting device requires the use of a power resistor, such as a fuse resistor. Because the fuse resistors are all winding resistors, the fuse resistors can not be rapidly fused in a low-current fault state, but can continuously generate heat and generate high temperature of more than 300 ℃. This temperature is much higher than the temperature resistance of the housing and therefore can cause the housing in contact with the fuse resistor to melt through, creating an unpredictable hazard.
In order to solve the problem, the current manufacturers generally adopt a temperature fuse resistor or a current fuse resistor, the two fuse resistors can be quickly fused even in a low-current fault state, and continuous high temperature cannot be generated. However, such fuse resistors are expensive and frequently replaced, which results in high cost and troublesome replacement.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the utility model, are within the scope of the utility model.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms a, an, etc. do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.
The circuit board according to the embodiment of the first aspect of the present invention will be described in detail with reference to the drawings.
As shown in fig. 1, the circuit board according to the embodiment of the first aspect of the present invention includes a main board 1, a support 2, and a fuse resistor. The support 2 is electrically connected or/and fixed on the mainboard 1; the fuse resistor comprises a main body 3 and two pins 4 connected to two ends of the main body 3, wherein the two pins 4 are welded on the support 2 and electrically connected with the support 2 to suspend the main body 3 above the main board 1.
Fuse resistance on this circuit board passes through support 2 and indirectly connects on mainboard 1, and support 2 can connect on mainboard 1 also can connect on the power pack of placing mainboard 1 to make fuse resistance be in unsettled state. Therefore, if the circuit board is assembled into the power supply box, the fuse resistor is located at the middle position of the box so as to be away from both sides of the power supply box, and even if the fuse resistor continuously generates heat due to a low current fault, the power supply box is not burned out. The design structure effectively solves the problem that the power supply box is easily burnt out by the fuse resistor, does not need to use a temperature fuse resistor or a current fuse resistor with high price, saves the manufacturing and maintenance cost and avoids the trouble of replacement.
Further, as shown in fig. 1, the stand 2 is formed in a plate shape, and the stand 2 is vertically provided on the main plate 1. The support 2 and the mainboard 1 are perpendicular to each other, so that the stability of the support and the mainboard can be ensured, and the space utilization rate of the circuit board can be improved. Preferably, the stand-offs 2 are welded to the main board 1.
Further, the support 2 is a copper clad phenolic glass cloth laminated board. The main board 1 and the support 2 of the circuit board are mainly composed of a substrate, copper foil, adhesive and electronic components for realizing circuit functions. The substrate is an insulating layer board composed of polymer synthetic resin and reinforcing material, the surface of the substrate is covered with a layer of pure copper foil with high conductivity and good weldability, and the pure copper foil is firmly covered on the substrate through an adhesive. The substrate of the support 2 of the circuit board is a copper-clad phenolic glass cloth laminated board, the copper-clad phenolic glass cloth laminated board is a laminated product formed by hot pressing alkali-free glass cloth which is soaked with epoxy phenolic resin, the board surface of the laminated product is light yellow, and if tricyanodiamine is used as a curing agent, the board surface is light green. The copper foil-coated phenolic glass cloth laminated board has the advantages of light weight, good electrical and mechanical properties and convenient processing, and is suitable for equipment with higher working temperature and working frequency.
Further, as shown in fig. 1, the main body 3 of the fuse resistor is parallel to the main board 1. The main body 3 of the fuse resistor is parallel to the main board 1, and the two pins 4 are perpendicular to the support 2, so that the space utilization rate of the circuit board can be ensured by the structure.
Further, as shown in fig. 1, a certain gap is left between the main body 3 of the fuse resistor and the support 2, so that heat is not directly transferred to the support 2 when the fuse resistor generates heat, which is beneficial to protecting the support 2 and prolonging the service life of the support 2.
As shown in fig. 2, the power supply box of the embodiment of the second aspect of the utility model includes an upper cover 5, a lower cover 6, and the circuit board. The lower cover 6 is buckled with the upper cover 5; the circuit board is disposed in the lower cover 6. Because the power supply box comprises the circuit board, the power supply box is sufficiently separated from the fuse resistance pin, and the power supply box can effectively solve the problem that the shell is easily melted through.
The lamp provided by the embodiment of the third aspect of the utility model comprises the illuminating body and the power box, wherein the illuminating body is electrically connected with the power box. Because the lamp comprises the power supply box, the lamp can also effectively solve the problem that the shell is easily melted through.
