## Abstract

A connector housing includes a terminal receiving chamber and a pair of lances for locking the terminal on both sides of the terminal receiving chamber. A terminal pullout jig inserted into the connector housing displaces the lances to respective unlocking positions, thus pulling out the terminal from the terminal receiving chamber. The connector housing includes a pair of unlocking wall portions configured to be elastically deformed integrally with the pair of lances respectively. The terminal pullout jig includes an unlocking arm portion configured to displace the pair of the lances to the respective unlocking positions, and a terminal pressing portion for pressing the terminal in a terminal pullout direction.

## Claims

### Claim 1

A terminal pullout structure of a connector, comprising:
a terminal receiving chamber provided in a connector housing and configured to receive a terminal;
a pair of lances for locking the terminal by an elastic deformation on both sides of the terminal receiving chamber; and
a terminal pullout jig configured to pull out the terminal from the terminal receiving chamber by being inserted into the connector housing and displacing the pair of the lances to respective unlocking positions,
wherein
the connector housing includes a pair of unlocking wall portions configured to be elastically deformed integrally with the pair of the lances respectively and arranged in an insertion space for inserting therebetween the terminal pullout jig, slits provided to each of the lances in an area on opposite side of the unlocking wall portions and extending in the longitudinal direction of the terminal receiving chamber and
the terminal pullout jig includes:
an unlocking arm portion configured to enter into between the pair of the unlocking wall portions in an inserting process into the connector housing and configured to shift the pair of the unlocking wall portions in a direction for expanding an interval between the pair of the unlocking wall portions to thereby displace the pair of the lances to the respective unlocking positions, and
a terminal pressing portion for pressing the terminal in a terminal pullout direction in an inserting process after the pair of the lances are displaced to the respective unlocking positions.

### Claim 2 (depends on 1)

The terminal pullout structure of the connector according to claim 1 wherein the terminal pullout jig has a prying force restricting portion for restricting an inclination of the unlocking arm portion inserted into the connector housing.

### Claim 3 (depends on 2)

The terminal pullout structure of the connector according to claim 2 wherein the prying force restricting portion is slidably provided in the unlocking arm portion and is biased to a distal end side of the unlocking arm portion by a biasing member.
