Problems solved by technology

[0003] When fixing the rectifier diode on the circuit board, it is usually necessary to insert the pins on it into the through holes on the circuit board and then fix the inserted pins by soldering, but when used on vehicles in some cold regions , it is easy to be bumped by the vehicle and the soldering part is loosened, and the low temperature also affects the conductivity of the rectifier diode. The diode has heat preservation effect, which improves the stability during use

Embodiment Construction

[0021] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following will further elaborate the present invention in conjunction with specific embodiments. figure 1 view direction.

[0022] Such as Figure 1-4 As shown, a rectifier diode according to the present invention includes a main body 1 and pins 2 installed at its two ends, the vertical section of the pin 2 runs through the conduction hole on the surface of the circuit board, and the pin 2 The outer side of the vertical section is fixedly connected with an inverted foot 3, and the bottom of the main body 1 is provided with a squeeze bag 4, which is located between the two pins 2; when working, insert the two pins 2 on the main body 1 into the circuit When the via hole on the board is inside, the extrusion bag 4 is extruded and deformed to both sides, pushing the two pins 2 away from each other, so that the inverted pin 3 on the pin 2 is s...

Abstract

The invention belongs to the technical field of diodes, in particular to a rectifier diode comprising a body and pins which are mounted at the two ends of the body. The vertical sections of the pins penetrate through the through holes on the surface of a circuit board. Inverted pins are fixedly connected on the outer side of the vertical sections of the pins. A pressing capsule is arranged at thebottom of the body and positioned between the two pins. The pressing capsule and the inverted pins are arranged, and the pressing capsule is extruded to deform to the two sides and the pressing capsule is closely fit with the body when the two pins on the body are inserted into the through holes on the circuit board so that thermal insulation of the body can be realized and the stability of conduction can be enhanced; meanwhile, the inverted pins on the pins are clamped at the bottom of the circuit board under the push of the restoring force of the pressing capsule so as to have a good fixingeffect on the pins and improve the stability of connection; meanwhile, the pins are tightly adhered to the circuit board when the pressing capsule pushes the pins outward, thereby improving the stability of conduction.

Description

technical field [0001] The invention belongs to the technical field of diodes, in particular to a rectifying diode. Background technique [0002] A rectifier diode is a semiconductor device that converts AC power into DC power. Usually it consists of a PN junction with two terminals, positive and negative. The most important characteristic of a diode is unidirectional conductivity. In the circuit, current can only flow in from the positive terminal of the diode and flow out from the negative terminal. [0003] When fixing the rectifier diode on the circuit board, it is usually necessary to insert the pins on it into the through holes on the circuit board and then fix the inserted pins by soldering, but when used on vehicles in some cold regions , it is easy to be bumped by the vehicle and the soldering part is loosened, and the low temperature also affects the conductivity of the rectifier diode. The diode has a thermal insulation effect, which improves the stability dur...
