Method of inserting connection terminals into half-fitting prevention connector
View Patent ↗In a half-fitting prevention connector ( 31 ) of the invention, a fitting detection member ( 60 ) is moved to a proper-fitting detecting position in a female connector ( 40 ) before connection terminals are automatically inserted by an automatic terminal inserting machine. As a result of this movement, a rear end of the fitting detection member ( 60 ) substantially coincides with a rear end surface of the housing of the female connector ( 40 ), so that the connection terminals can be automatically inserted into terminal accommodating chambers ( 40 a ) by the automatic terminal inserting machine.
1. An inserting method of inserting connection terminals into a half-fitting prevention connector including a first connector housing having a flexible lock arm, a second connector housing having an engaging portion for engaging a lock portion of the lock arm and adapted to be connected to the first connector housing by engagement between the lock portion and the engaging portion at the time of fitting with the first connector housing, and a fitting detection member attached over the first connector housing slidably along fitting direction of the connector housings so as to detect a half-fitted state of the connector housings according to whether or not the fitting detection member is able to slidingly move from a first position before fitting of the first and second connector housings to a second position after the fitting of the first and second connector housings, the inserting method comprising the steps of:
moving the fitting detection member by sliding the fitting detection member over the first connector housing to a position where a rear end of the fitting detection member substantially coincides with a rear end surface of the first connector housing or a position where the rear end of the fitting detection member is located forwardly of the rear end surface of the first connector housing;
inserting the connection terminals into the first connector housing;
moving the fitting detection member by sliding the fitting detection member over the first connector housing to the first position where the rear end of the fitting detection member projects rearwardly of the rear end surface of the first connector housing;
effecting an operation of engaging the first connector housing with the second connector housing; and
indicating a half-fitted connection state of the first connector housing and the second connector housing,
wherein the fitting detection member is retained in the first position and prevented from slidingly moving to the second position if the first connector housing and the second connector housing are in the half-fitted connection state and the fitting detection member is slidingly movable from the first position to the second position if the first connector housing and the second connector housing are not in the half-fitted connection state.
2. The inserting method of the connection tenninals into the half-fitting prevention connector according to claim 1 , wherein the connection terminals are automatically inserted into the first connector housing by an automatic terminal inserting machine.
3. The inserting method of the connection terminals into the half-fitting prevention connector according to claim 1 , wherein the fitting detection member is located at the second position when the connection terminals are inserted into the first connector housing.
4. The inserting method of the connection terminals into the half-fitting prevention connector according to claim 3 , wherein the rear end of the fitting detection member is flush with the rear end surface of the first connector housing when the fitting detection member is located at the second position.
5. The inserting method of the connection terminals into the half-fitting prevention connector according to claim 4 , further comprising the steps of moving the fitting detection member to the second position and detecting a complete fitting of the first and second connector housing.
6. The inserting method of the connection terminals into the half-fitting prevention connector according to claim 1 , wherein a direction of the slidable movement of the fitting detection member from the first position to the second position is in an axial direction along the engaging direction of the first connector housing and the second connector housing.
7. The inserting method of the connection terminals into the half-fitting prevention connector according to claim 1 , wherein the fitting detection member is attached over outer peripheries of the first connector housing slidably in an axial direction along an engaging direction of the first connector housing and the second connector housing.
