Card edge connector

Abstract

The invention discloses a card edge connector which comprises an insulation body and a plurality of conductive terminals fixed in the insulation body. The insulation body comprises a slot which is concaved backwards from the front surface. Each of the conductive terminals comprises a first terminal and a second terminal, wherein the first terminals are arranged on the upper side of the slot and extend to the slot, and the second terminals are arranged on the lower side of the slot and extend to the slot. Each of the first terminals comprises a first contact portion and a first extending portion, wherein the first contact portions extend out of the insulation body slot, and the first extending portions are arranged at the back of the insulation body and provided with first clamp portions protruding inwards. Each of the second terminals comprises a second extending portion which extends out of the back of the insulation body and is provided with a second clamp portion protruding inwards. Second slots are formed between the first clamp portions and the second clamp portions for clamping a circuit board. The connection mode of the card edge connector with the circuit board is convenient, and phenomena of missing soldering and the like through a welding mode are prevented.

Description

【Technical field】 [0001] The invention relates to a card edge connector, in particular to a card edge connector used for electrical connection with a circuit board. 【Background technique】 [0002] An existing card edge connector, such as a card edge connector used in a notebook computer, generally includes an insulating body and a plurality of conductive terminals disposed in the insulating body. The insulating body includes a slot extending in the longitudinal direction and a plurality of terminal slots arranged at intervals on the upper and lower sides of the slot. The conductive terminal includes a vertically arranged base, a contact portion extending from one end of the base toward one side, a welding portion extending from the other end of the base toward the other side, and extending from the base toward one side and located between the contact portion and the welding portion Between the holding part. The soldering parts of the conductive terminals are arranged behin...

AI Technical Summary

Problems solved by technology

With such a design, the conductive terminals can be well fixed on the circuit board, but due to the small size of the card edge connector, the gap between adjacent conductive terminals is very small, and they are easily connected to each other during welding to form a short circuit. If the internal coplanarity is not well controlled, it will be easier to form empty welding

In addition, this type of connector is used for expansion, and sometimes it will be idle when the terminal is not in use, but the system manufacturer will still solder it on the circuit board, which will increase the cost accordingly
