Abstract
Abstract An electric connector includes a connector housing (A) having a plurality of terminal receiving chambers (5) aligned side by side in at least one lateral row, a through-path (9) formed through one side wall (8) of the housing so as to communicate with the respective terminal receiving chambers and a terminal lock member (B) inserted into the through-path through two stages of a temporary lock position and a normal lock position, the terminal lock member having flexible lock arms (19) for allowing terminals (C) to be inserted into the terminal receiving chambers at the temporary lock position, having lock protrusions for engaging with the terminals at a normal insertion position to prevent the terminals from coming off, and further having fixing lock rods (23) for engaging with the terminals which are in the normal insertion position at the normal lock position, wherein each of the lock protrusions (20) of the flexible lock arms is formed so as to be wide enough to be engageable with two adjacent terminals (C) which are in the normal insertion position at the normal lock position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
An electric connector comprising: a connector housing having a plurality of terminal receiving chambers aligned side by side in at least one lateral row, a through-path formed through one side wall of said housing so as to communicate with said respective terminal receiving chambers; a terminal lock member inserted into said through-path through two stages of a temporary lock position and a normal lock position, said terminal lock member having flexible lock arms for allowing terminals to be inserted into said terminal receiving chambers at said temporary lock position, having lock protrusions for engaging with said terminals at a normal insertion position to prevent said terminals from coming off, and each of said lock protrusions of said flexible lock arms being formed so as to be wide enough to be engageable with two adjacent terminals which are in said normal insertion position at said normal lock position; and fixing lock rods for engaging with said terminals which are in said normal insertion position at said normal lock position.
Claim 2
Dependent Claim
168 words
An electric connector comprising: a connector housing having a plurality of terminal receiving chambers aligned side by side in at least one lateral row, a through-path formed through one side wall of said housing so as to communicate with said respective terminal receiving chambers; a terminal lock member inserted into said through-path through two stages of a temporary lock position and a normal lock position, said terminal lock member having flexible lock arms for allowing terminals to be inserted into said terminal receiving chambers at said temporary lock position, having lock protrusions for engaging with said terminals at a normal insertion position to prevent said terminals from coming off, and each of said lock protrusions of said flexible lock arms being formed so as to be wide enough to be engageable with two adjacent terminals which are in said normal insertion position at said normal lock position; and fixing lock rods for engaging with said terminals which are in said normal insertion position at said normal lock position.
Claim 3
Dependent Claim
91 words
An electric connector according to claim 1, wherein said terminal lock member includes a lock member body having a side plate portion for closing an opening portion of said through-path, a partition plate portion provided so as to be perpendicular to said side plate portion, and a back plate portion provided at rear ends of said side and partition plate portions, and said flexible lock arms and said fixing lock rods are provided alternately, through slits, from said back plate portion to a front end portion of said partition plate portion.
Claim 4
Dependent Claim
192 words
An electric connector according to claim 2 further comprising: a hook formed, through a notch, on a front end surface of said partition plate portion of said terminal lock member; a saddle-shaped lock protrusion formed, through a recess portion, on a rear end surface of said partition plate portion; a lock protrusion provided to project on one side of said through-path to which said terminal lock member inserted; and an elastic lock arm having a lock protrusion provided on the other side of said through-path, wherein said terminal lock member is held in said temporary lock position when said hook on the front end surface of said partition plate portion gets over the lock protrusion in said through-path and the lock protrusion on the rear end surface engages with the lock protrusion of said elastic lock arm, while said terminal lock member is held in said normal lock position when said terminal lock member is further inserted into the inside of said through-path from said temporary lock position and the lock protrusion of said elastic lock arm engages with said recess portion in the rear end surface of said side plate portion.
Claim 5
Dependent Claim
39 words
An electric connector according to claim 3, further comprising: an unlock-jig insertion hole provided so as to extend from the front end surface of said connector housing to the lock protrusion of said elastic lock arm facing said through-path.
Claim 6
Dependent Claim
108 words
An electric connector according to claim 1 further comprising: a plurality of terminal receiving holes are formed side by side in two, upper and lower stages in said connector housing, portions of said terminal receiving holes in front of said through-path are divided into upper and lower sections by a center partition wall, wherein portions of said terminal receiving holes in the rear of said through-path are sectioned by upper and lower partition walls on the opposite side of a cavity portion, said unlock-jig insertion hole is provided in said center partition wall, and said elastic lock arm having the lock protrusion is provided in said cavity portion.
Claim 7
Dependent Claim
108 words
An electric connector according to claim 2 further comprising: a plurality of terminal receiving holes are formed side by side in two, upper and lower stages in said connector housing, portions of said terminal receiving holes in front of said through-path are divided into upper and lower sections by a center partition wall, wherein portions of said terminal receiving holes in the rear of said through-path are sectioned by upper and lower partition walls on the opposite side of a cavity portion, said unlock-jig insertion hole is provided in said center partition wall, and said elastic lock arm having the lock protrusion is provided in said cavity portion.
Claim 8
Dependent Claim
108 words
An electric connector according to claim 3 further comprising: a plurality of terminal receiving holes are formed side by side in two, upper and lower stages in said connector housing, portions of said terminal receiving holes in front of said through-path are divided into upper and lower sections by a center partition wall, wherein portions of said terminal receiving holes in the rear of said through-path are sectioned by upper and lower partition walls on the opposite side of a cavity portion, said unlock-jig insertion hole is provided in said center partition wall, and said elastic lock arm having the lock protrusion is provided in said cavity portion.
Claim 9
Dependent Claim
108 words
An electric connector according to claim 4 further comprising: a plurality of terminal receiving holes are formed side by side in two, upper and lower stages in said connector housing, portions of said terminal receiving holes in front of said through-path are divided into upper and lower sections by a center partition wall, wherein portions of said terminal receiving holes in the rear of said through-path are sectioned by upper and lower partition walls on the opposite side of a cavity portion, said unlock-jig insertion hole is provided in said center partition wall, and said elastic lock arm having the lock protrusion is provided in said cavity portion.
