Connector and electronic device

A connector configured to be mounted on a panel, the connector comprising:

• a housing having a channel that passes through a first end and a second end of the housing, wherein a first connection portion is disposed on the second end of the housing and configured to be connected to a second connector;
• and
• a conductive core disposed in the channel, wherein a solder leg is disposed on a first end of the conductive core and protrudes from the first end of the housing, and is configured to be soldered to a circuit board;
• and
• a fastening structure configured to fasten the housing to the panel,
• wherein an outwardly-tilted spring is disposed on an outer periphery of the conductive core, a horn-shaped opening is disposed inside the channel,
• a first abutment surface is disposed in the channel and a second abutment surface is disposed in the conductive core,
• a positioning through hole is disposed in the channel,
• an outer peripheral surface of the conductive core and an inner wall of the positioning through hole cooperate with each other,
• when the conductive core is inserted into the channel, the horn-shaped opening abuts against an outer side of the outwardly-tilted spring so that the outwardly-tilted spring is elastically deformed toward an inner side of the conductive core,
• after the conductive core is further pushed to enable the outwardly-tilted spring to pass through the horn-shaped opening, the outwardly-tilted spring returns to an outwardly-tilted state under an action of elastic force of the outwardly-tilted spring, and
• when the conductive core is pulled, the outwardly-tilted spring abuts against an end face of the horn-shaped opening, so that the conductive core is prevented from being pulled out.
