Connector
It is aimed to provide a connector of a novel structure capable of suppressing or preventing the transmission of the swing of a wire to a terminal in a connector. A connector 10 is provided with a housing 16 for accommodating a terminal 12 , a back retainer 20 mounted in a rear end part of the housing 16 from which a wire 18 connected to the terminal 12 is pulled out, a wire insertion hole 62 provided in the back retainer 20 , and a wire holding piece 72 projecting in a pull-out direction of the wire 18 from a peripheral edge part of the wire insertion hole 62 . The wire 18 pulled out from the wire insertion hole 62 is tied and fixed to the wire holding piece 72 by a tying tool 82.
1. A connector, comprising:
a housing for accommodating a terminal;
a back retainer mounted in a rear end part of the housing;
a wire connected to the terminal being pulled out from the rear end part of the housing;
a wire insertion hole provided in the back retainer; and
a pair of wire holding pieces projecting in a pull-out direction of the wire from a peripheral edge part of the wire insertion hole, the pair of the wire holding pieces respectively disposed on opposite sides of the wire insertion hole,
wherein the wire is pulled out from the wire insertion hole and is tied and fixed to each of the pair of wire holding pieces by a tying tool.
2. The connector according to claim 1 , wherein
the pair of wire holding pieces are cantilevered from the peripheral edge part of the wire insertion hole and provided to project at two positions facing each other in a radial direction of the wire insertion hole, and
the wire is sandwiched and tied and fixed between the pair of wire holding pieces from both sides in the radial direction.
3. The connector according to claim 1 , further comprising:
a pair of outer peripheral walls formed as projecting pieces respectively separated on outer peripheral sides of the pair of wire holding pieces and projecting in the pull-out direction of the wire; and
an annular cover wall projecting from projecting end sides of the pair of outer peripheral walls toward the wire holding pieces and coupling the projecting end sides of the pair of outer peripheral walls to each other,
wherein
a pair of accommodation regions for the tying tool are formed by a pair of clearances between the pair of wire holding pieces and the pair of outer peripheral walls and
escape of the tying tool from the pair of accommodation regions is obstructed by the tying tool contacting the annular cover wall.
4. The connector according to claim 1 , wherein each of the pair of wire holding pieces is deflectable and deformable outward in the radial direction.
5. The connector according to claim 1 , further comprising:
wire pressing portions respectively provided to project radially inwardly of inner peripheral surfaces of the pair of wire holding pieces.
6. The connector according to claim 5 , wherein a radial separation distance between projecting tip parts of the wire pressing portions is set smaller than an outer diameter of the wire.
7. The connector according to claim 5 , wherein each of the wire pressing portions has a hemispherical shape.
