Claims

[Scope of utility model registration request]

Inside the housing 1, there is a space 2a for inserting the connection terminal 3.
and a cavity 5a for fitting the retainer 4 for preventing the connecting terminal 3 from coming off, are formed with the partition wall 6a as a boundary,
A locking piece 7a in the connection terminal insertion direction is formed in the partition wall 6a by a notch so that it can be bent at one end, and when the connection terminal 3 is inserted into the cavity 2a, the locking piece 7a is bent. , a protrusion 8a that fits into the locking hole 3a of the connection terminal 3 is provided, and the retainer 4
On both side walls of the insertion cavity 5a bordering the locking piece 7a, there are protrusions 9a that are shifted back and forth in the insertion direction;
9b, and the retainer 4 has protrusions 11a and 11b that, when fitted into the cavity 5a, ride over and engage with the protrusions 9a and 9b on both side walls.
0a, 10b, and a piece 1 that comes into contact with the locking piece 7a to prevent the locking piece 7a from bending into the space 5a.
In the housing structure of the connection terminal in which the retainer 4 has two projecting pieces 10a and 10,
b further extends from the protrusions 9a, 9b in the retainer 4 insertion direction, and below the locking piece 7a of the retainer fitting cavity 5a peripheral wall is a side peripheral wall of the protrusions 9a, 9b of the cavity 5a. On the other hand, the protrusion 1 has a gap 15 through which the protrusion extension 13 can pass.
4, and the protruding piece extension part 13 has its tip end in the gap 15 when the protrusion on the front side of the protruding piece of the retainer 4 rides over the protrusion on the circumferential wall of the cavity 5a and locks therein.
A housing structure of a connecting terminal characterized in that the length is set to be located at .
