Husband consumed by wrong ends in here? (7)

I believe the answer is:
ashtray
'ends in here?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'husband consumed by wrong' is the wordplay.
'husband' becomes 'h' (abbreviation).
'consumed by' means one lot of letters goes inside another (inserted letters get consumed).
'wrong' becomes 'astray' (going astray is going wrong).
'h' placed inside 'astray' is 'ASHTRAY'.
Can you help me to learn more?
(Other definitions for ashtray that I've seen before include "Receptacle for cigarette butts" , "Where to rest cigarette" , "Smoker's receptacle" , "Receptacle for tobacco detritus" , "Place for detritus from cigarettes, cigars etc" .)
