Grid-type detachable electrical connector

Abstract

A grid type detachable electrical connector of comprises a board end male head and a terminal female end, A male head of that plate end comprise a male head body and a plurality of clip terminals, theclip terminal has a first solder pin for soldering to the tap PCB, The female terminal comprises a female terminal body, a plurality of connecting terminals and a locking member, wherein a slot is formed on the female terminal body, and the connecting terminal is provided with a second welding pin and a terminal pin for welding to the PCB, so that the lead can be locked to the connecting terminalthrough the locking member to realize the function of connecting the lead; The plug-in and plug-out expansion structure formed by the slot and the terminal pin can plug and pull the male head of theconnecting board end, so that when the EMC function is added in the user product design such as the frequency converter design, the function can be expanded by connecting the male head of the board end to the terminal bus end; Instead of setting or reserving an expansion interface on the PCB, the design and application elasticity of the product are improved, the space utilization of the product isimproved, and the layout difficulty of the PCB is reduced.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a grid-plate type tappable electrical connector which can be tapped and expanded. Background technique [0002] Electrical connectors, also known as terminal blocks or terminal blocks, can quickly realize the connection between wires and wires, wires and circuit boards, and circuit boards. The form and structure of connectors are ever-changing. With different application objects, frequencies, power, and application environments, there are various electrical connectors with different structures. [0003] see figure 1 In the prior art, the grid-type electrical connector 100 or barrier-type terminal block only has a wiring module 101 and pins 102 soldered to the PCB, so as to realize the electrical connection of the wires to the PCB 200 . That is to say, the existing grid-type electrical connectors can only be used to connect PCBs and wires. When a PCB needs to be expanded due...

Problems solved by technology

That is to say, the existing grid-type electrical connectors can only be used to connect PCBs and wires. When a PCB needs to be expanded due to structural or functional requirements, a set of board-to-board male and female connectors can only be installed on the two PCBs. In this way, the wiring connector and the board end connector are used independently on the PCB, occupying a large PCB area and product structure space, which is not conducive to product miniaturization design

And the use of multiple connectors, the cost of components and the cost of PCBA are relatively high
