Problems solved by technology

This kind of resistance can meet the needs to a certain extent, but its disadvantages are: when the resistance is welded, manual insertion is required, which is time-consuming, and when there is a floating height requirement, it is difficult to realize automation; when the resistance is close to the PCB board, the PCB board is easy to heat up , it is not easy to pass the safety test; resistance welding requires wave soldering, the welding is unstable, and the product defect rate is high

Abstract

The invention discloses a high-power chip resistor which comprises a resistor body and also comprises end caps and a bracket, wherein the end caps are arranged at two ends of the resistor body and are connected with outgoing ends of the resistor body, the bracket is fixed at the bottoms of the end caps. According to the high-power chip resistor, the end caps are connected with the outgoing ends of the resistor body and are supported by the bracket and are connected with a PCB (Printed Circuit Board) through the bracket, thus the lead connection of the conventional resistor is avoided, the welding efficiency of the chip resistor is increased, and the working hour is saved; and meanwhile, after the resistor floats, the heat radiating space is enlarged, a good heat radiating property is achieved, heat can not be transmitted to the PCB to ensure that the PCB is easily demonstrated by safety requirements, and the space of the PCB is saved. In addition, after the resistor floats, a reflow soldering process can be used, and is stable in welding, and thus the yield of products is increased.

Description

technical field [0001] The invention relates to a high-power chip resistor and belongs to the technical field of resistors. Background technique [0002] As an important electronic component, resistors are widely used in electrical equipment. Most of the current resistors include a resistor body and a lead wire, and the lead wire is connected to the lead end of the resistor body to form a resistor. This kind of resistance can meet the needs to a certain extent, but its disadvantages are: when the resistance is welded, manual insertion is required, which is time-consuming, and when there is a floating height requirement, it is difficult to realize automation; when the resistance is close to the PCB board, the PCB board is easy to heat up , It is not easy to pass the safety test; resistance welding requires wave soldering, the welding is unstable, and the product defect rate is high. Contents of the invention [0003] In order to overcome the shortcomings of the prior art,...
