How to say "plug" in Japanese

• プラグCommon
  nounThe loanword for a plug in the electrical sense: the connector you insert into an outlet. When 'plug' means the hardware rather than something sealing a hole, this is the word.
• 栓せんJLPT N2approx.Common
  nounThe plug that seals an opening: a cork in a bottle, a bung, a stopper in a drain. Use it when 'plug' means something that blocks or closes a hole, not an electrical plug.
  シャンパンの栓せんがぽんと音おとを立たててとんだ。↗

  The champagne cork popped out.
• 詰めるつめるJLPT N3approx.Common
  ichidan verb, transitive verbA verb: to plug a hole by stuffing something into it. Its core senses are to stuff, cram or pack, so it suits 'plug' only as a verb, never for the physical device.
  この穴あなを何なんかで詰つめなくては。↗

  We've got to fill this hole with something.
• 差し込みさしこみCommon
  nounCovers the electrical sense but also means the outlet or power point, so it often points to the socket side rather than the plug itself; プラグ is the safer choice for the device.

Use 「プラグ」 for an electrical plug or connector, 栓 for a stopper or cork sealing a hole, 「詰める」 when plugging means stuffing something into an opening, and 「差し込み」 mainly for the outlet or insertion point.
