Connector

1. A connector, comprising:

a first housing and a second housing connectable to each other;

a detector having opposite front and rear ends and being arranged movably to a standby position and a detection position with respect to the first housing, the detector being allowed to move to the detection position when the first and second housings are connected properly;

two second terminal fittings arranged in the second housing; and

a shorting terminal arranged in the second housing to short-circuit the second terminal fittings,

the detector including an operating portion at the rear end of the detector, two laterally spaced guides projecting forward from the operating portion toward the front end of the detector, and a releasing portion extending between and connecting the guides at the front end of the detector so that the operating portion, the guides and the releasing portion define a frame shape, the releasing portion being disposed and configured for releasing a short-circuit state of the second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position, wherein:

a recess into which the releasing portion enters is open in a front surface of the first housing, and

a back surface of the recess in the first housing defining a restricting surface contactable by a rear end of the releasing portion when the detector is at the standby position.

2. The connector of claim 1 , wherein:

the two guides are parallel to a front-rear direction.

3. The connector of claim 1 , further comprising two detection arms projecting forward from the operating portion at positions on the operating portion laterally inward of the guides.

4. A connector, comprising:

a first housing having a forwardly open recess, a back surface of the recess in the first housing defining a restricting surface;

a second housing connectable to the first housing, two second terminal fittings and a shorting terminal arranged in the second housing, the shorting terminal arranged in the second housing to short-circuit the second terminal fittings;

a detector arranged in the first housing and being movable forward from a standby position to a detection position with respect to the first housing, the detector being allowed to move to the detection position when the first and second housings are connected properly, the detector includes two guides arranged in parallel in a direction intersecting a front-rear direction, an operating portion extending between rear parts of the guides, and a releasing portion extending between front parts of the guides, the releasing portion releasing a short-circuit state of the second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position, the releasing portion contacting the restricting surface when the detector is at the standby position,

wherein:

a biasing member is assembled with the second housing, and

the biasing member accumulates a biasing force by being pressed by the detector moving from the standby position to the detection position.

5. A connector, comprising:

a first housing and a second housing connectable to each other;

a detector having opposite front and rear ends and being arranged movably to a standby position and a detection position with respect to the first housing, the detector being allowed to move to the detection position when the first and second housings are connected properly;

two second terminal fittings arranged in the second housing; and

a shorting terminal arranged in the second housing to short-circuit the second terminal fittings,

the detector including an operating portion at the rear end of the detector, two laterally spaced guides projecting forward from the operating portion toward the front end of the detector, two detection arms projecting forward from the operating portion at positions on the operating portion laterally inward of the guides, and a releasing portion extending between and connecting the guides at the front end of the detector so that the operating portion, the guides and the releasing portion define a frame shape, the releasing portion being disposed and configured for releasing a short-circuit state of the second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position, wherein:

a biasing member is assembled with the second housing, and

the biasing member accumulates a biasing force by being pressed by the detector moving from the standby position to the detection position.

6. The connector of claim 5 , wherein:

a recess into which the releasing portion enters is open in a front surface of the first housing, and

a back surface of the recess in the first housing defining a restricting surface contactable by a rear end of the releasing portion when the detector is at the standby position.

7. A connector, comprising:

a first housing and a second housing connectable to each other;

a detector having opposite front and rear ends and being arranged movably to a standby position and a detection position with respect to the first housing, the detector being allowed to move to the detection position when the first and second housings are connected properly;

two second terminal fittings arranged in the second housing; and

a shorting terminal arranged in the second housing to short-circuit the second terminal fittings,

the detector including an operating portion at the rear end of the detector, two laterally spaced guides projecting forward from the operating portion toward the front end of the detector, two detection arms projecting forward from the operating portion at positions on the operating portion laterally inward of the guides, and a releasing portion extending between and connecting the guides at the front end of the detector so that the operating portion, the guides and the releasing portion define a frame shape, the releasing portion being disposed and configured for releasing a short-circuit state of the second terminal fittings by the shorting terminal as the detector reaches the detection position from the standby position, wherein each of the guides has opposite upper and lower surfaces spaced apart in a vertical direction, the detection arms projecting forward from positions on the operating portion above the guides in the vertical direction.

8. The connector of claim 7 , wherein the releasing portion is lower than the detection arms in the vertical direction.

9. The connector of claim 7 were in the releasing portion is aligned with the lower surfaces of the guides and is lower than the upper surfaces of the guides.

10. The connector of claim 7 , wherein the second housing includes lock portions and the first housing includes a resiliently deflectable lock arm with lock pieces that engage rear sides of the lock portions on the second housing when the first and second housings are connected, the detector further comprising facing arms projecting forward from the operating portion at positions vertically below the detection arms, the detection arms and the facing arms sandwiching the lock pieces and the lock portions from upper and lower sides when the detector is at the detection position.
