The present invention relates to a female connector assembly, and more particularly to a female connector assembly that can securely secure the position of the terminal in the housing, and can be firmly coupled to the male connector and the female connector.

The electrical connector generally includes a housing that houses at least one conductive terminal. The terminal is then electrically connected to a separate electrical component, such as a wire. On the other hand, the connector is divided into a female connector and a male connector and the female and male connectors are always provided in pairs and are coupled to each other.

If the terminals are improperly mounted to the housing, the quality of the electrical connection is poor. If the terminal is not fully inserted into the housing during the initial assembly of the connector, or if the terminal is shaken or pulled out of its fully mounted state while using the connector, the terminal is improperly mounted in the housing.

This problem is often encountered in automobiles where electrical components are subjected to almost constant vibration during use. In order to avoid these problems, recent automobiles are equipped with a terminal position positioning device (TPA) for detecting incomplete insertion of a terminal.

However, in using a terminal positioning device that has been used in the past, when the terminal positioning device detects that the terminal is not completely inserted, a position search for positioning the incompletely inserted terminal is necessary. This location search can be a time consuming task and add to the cost of assembling the connector assembly.

In addition, the locking protrusion 33 which is locked by the locking groove 22a formed in the upper plate 22 of the terminal 20 is protruded downward from the bottom surface of the upper plate 32 of the terminal positioning tool 30. In this way, the terminal positioning tool 30 is locked only when the terminal 20 is correctly inserted into the terminal accommodating hole 10b.

On the other hand, at the bottom of the front side of the coupling end through-hole 30a of the terminal positioning port 30, the terminal departure prevention jaw 34 which prevents the front departure of the terminal 20 together with the terminal departure prevention jaw 13 of the housing 10. ) Is formed to protrude.

The above-described inner seal 40 is compressed by the terminal positioning tool 30 in a state of being fitted to the outside of the front coupling end 11 to shield between the terminal positioning tool 30 and the outside of the front coupling end 11. The plurality of ribs 41 protrude at equal intervals on the inner and outer surfaces thereof.

The wire seal 50 described above is coupled to the outside of the end of the wire 3 and inserted into the terminal accommodating hole 10b together with the terminal 20 to shield the rear side of the terminal accommodating hole 10b. The plurality of ribs 51 are formed to protrude at equal intervals.

The connector positioning hole 60 described above fixes the male connector 2 inserted into the CPA insertion hole 10d formed at the other side of the housing 10 and inserted into the opening 10a. A locking plate 61 is formed to be caught by the CPA front stopper 17 formed at the upper rear side of the CPA insertion hole 10d of the housing 10 to prevent further forward travel, and a position spaced a predetermined distance from the rear end of the other side.

When the connector stopper 16 in the hole 10d is pushed up by the locking protrusion 2a of the male connector 2 and the male connector 2 is continuously inserted, the connector stopper 16 is removed as shown in FIG. 7B. The locking protrusion 2a of the male connector 2 is lowered and locked by the connector stopper 16.

In this way, in the state where the locking protrusion 2a of the male connector 2 is locked to the connector stopper 16, the user pushes the locking plate 61 forward to push the connector positioning tool 60 as shown in FIG. 7D. When positioned, the locking stop of the male connector 2 can be prevented from being released by pressing the connector stopper 16 to the tip of the connector positioning tool 60 to prevent the connector stopper 16 from lifting during use.

At this time, the locking plate 61 formed at the rear end of the connector positioning tool 60 is caught by the CPA front stopper 17 in the CPA insertion hole 10d to prevent the front flow, and the connector positioning tool 60 The pressing protrusion 63 formed at the front end of the hook is caught by the connector stopper 16 to prevent rear flow, and the support protrusion 64 of the connector positioning hole 60 is in close contact with the ceiling in the CPA insertion hole 10d.

Therefore, the CPA does not flow backwards and remains in a fixed state of the male connector 2 unless the user arbitrarily applies a lot of force to pull the latch plate 61 backward.
