Connector
A waterproof connector ( 10 ) includes a retainer ( 30 ) composed of divided bodies ( 31, 32 ), and a housing ( 11 ) including a retainer mounting portion ( 14 ) into which the retainer is to be mounted. The retainer mounting portion ( 14 ) includes a first mounting portion ( 16 ) into which a first of the divided bodies ( 31 ) is to be mounted and a second mounting portion ( 17 ) into which a second divided body ( 32 ) is to be mounted. The first and second divided bodies ( 31, 32 ) have facing surfaces ( 31 A, 32 A) facing each other. The first divided body ( 31 ) includes a projection ( 31 C) that projects toward the second divided body ( 32 ) from the facing surface ( 31 A) and a sensor detected portion ( 38 ) provided on a back surface ( 31 B) adjacent to the facing surface ( 31 A), and the second divided body ( 32 ) includes a recess ( 32 B) into which the projection ( 31 C) is to be fit.
1. A connector, comprising:
a housing having opposite front and rear ends and accommodating first, second and third terminals connected respectively to first, second and third wires so that the wires extend from the rear end of the housing, at least the first wire having a diameter different from diameters of the second and third wires, a retainer mounting portion being formed at the rear end of the housing; and
a retainer mounted in the retainer mounting portion of the housing, the retainer being formed from the first, second and third divided bodies, the first and second divided bodies abutting one another along a first division line, the second and third divided bodies abutting one another along a second division line and the third and first divided bodies abutting one another along a third division line, first, second and third through holes being formed through the retainer at the respective first, second and third division lines and defining diameters corresponding to the respective diameters of the first, second and third wires, the first divided body having at least one projection projecting toward the second divided body at the first division line and the second divided body having at least one recess at the first division line, the at least one recess receiving the at least one projection when the first, second and third divided bodies are assembled correctly with one another in the retainer mounting portion, and a sensor-detectable surface discontinuity extending in a front-rear direction on the first divided body at a specified position for detection by a sensor to confirm that the first divided body is in a specified position in the retainer mounting portion.
2. The connector of claim 1 wherein the at least one projection on the first divided body comprises two projections on opposite sides of the first through hole and the at least one recess on the second divided body comprises two recesses on opposite sides of the first through hole and at positions to receive the projections of the first divided body when the first, second and third divided bodies are assembled correctly with one another in the retainer mounting portion.
3. The connector of claim 1 , wherein the through holes are formed by semicircular recesses in the divided bodies that abut one another at the respective division lines.
4. The connector of claim 1 , wherein the diameters of the second and third through holes are substantially equal.
5. The connector of claim 4 , wherein the diameter of the first through hole is greater than the diameters of the second and third through holes.
6. The connector of claim 1 , wherein the retainer mounting portion and the retainer are substantially triangular.
7. The connector of claim 6 , wherein each of the divided bodies is substantially triangular.
