Problems solved by technology

The full surface mount pin is opposite to the separated through-hole pin, which can effectively overcome the shortcomings of the latter, but loses its advantages. It occupies less PCB board resources, can be produced by SMT technology, and has high assembly efficiency, but it is too Relatively poor current capability, poor mechanical connection strength

Embodiment Construction

[0023] refer to image 3 (A), the perforated pin 101 has a first installation head 201 , a first step 202 , a V-shaped anti-tin groove 203 , a V-shaped anti-slip groove 204 , a second step 205 and a second installation head 206 . Mounting head 201 and mounting head 205 each have inverted feet to facilitate alignment and assembly. The length of mounting head 201 can be smaller than the thickness of the module power supply PCB to be suitable for SMT process production. refer to image 3 (B, C), an embodiment of the surface-mounted pin 102 , on which there is a first soldering surface 211 , a small V-shaped anti-tin groove 212 , a small V-shaped anti-slip groove 213 , a step 214 , and a mounting head 215 . refer to image 3 (D, E), another embodiment of the surface mount type pin 102, with image 3 (B) The embodiment is different in that the steps 214 and the mounting head 215 are replaced by the second soldering surface 217 to form another surface mount pin 102 - 1 . Both th...

Abstract

The invention discloses a modular power supply pin structure, which includes a perforated pin, a surface mount pin and a high temperature resistant insulating part, and is characterized in that the insulating part combines the perforated pin, surface mounted tube The pins are positioned according to the definition of the industrial standard pins of the module power supply to obtain the pin structure of the module power supply. The modular power supply pin structure of the present invention has the advantages of both fully separated perforated pins and full surface mount tube pins, and overcomes the disadvantages of both. Power supply input and output pins adopt perforated pins, which have good overcurrent capability and strong mechanical connection strength; auxiliary function pins adopt surface mount pins and occupy less printed circuit board resources; surface mount pins after plastic packaging Combined with perforated pins, the mechanical strength is enhanced. Combined with the production process of the module power supply, the module power supply pin structure 100 can be produced by the SMT process to improve production efficiency.

Description

technical field [0001] The present invention relates to modular power supplies, and more particularly to pinouts of brick-type modular power supplies having an industry standard package. Background technique [0002] The power density of the current module power supply is getting higher and higher. The improvement of power density largely depends on the progress of technology, the performance development of components, and also benefits from the improvement of heat dissipation and packaging structure. Industry standard brick power pins are usually fully split through-hole, see figure 1 ; In recent years, there are also pins that are fully surface-mounted (SMT), see figure 2 . Fully separated perforated pins have good overcurrent capability and strong mechanical connection strength, but such pins need to provide through holes for installation and occupy more printed circuit (PCB) board resources. Other electronic components cannot be installed; and such pins cannot be pr...
