Abstract
A connector has a housing (10) with cavities (11) for receiving terminal fittings (21). Each cavity (11) has a lock (12) with a fastening portion (13) for locking the terminal fitting (21). A jig contact portion (14) is formed at the side of the fastening portion (13). A withdrawing jig (J) comes into sliding contact with the jig contact portion (14) to deform the lock (12) away from the terminal fitting (21) to cancel the locked state. The front end (14F) of the jig contact portion (14) is more backward than the front end (13F) of the fastening portion (13). Thus, a stroke of the sliding-contact accompanied by frictional resistance between the withdrawing jig (J) and the jig contact portion (14) is shortened, and frictional resistance is reduced during the insertion of the withdrawing jig (J).
Claims14
A connector, comprising:
- a housing (10) formed with at least one cavity (11) into which at least one terminal fitting (21) is insertable in an inserting direction (ID);
- a lock (12;
- 30;
- 40;
- 50;
- 60;
- 70) cantilevered substantially in the inserting direction (ID) along an inner wall of the cavity (11) and being resiliently deformable in a deformation direction (DD) to exit an insertion path for the terminal fitting (21), a fastening portion (13;
- 31;
- 41;
- 51;
- 61;
- 71) at an end of the lock (12;
- 30;
- 40;
- 50;
- 60;
- 70) for engaging and locking the terminal fitting (21) from a withdrawing side;
- at least one jig contact portion (14;
- 33;
- 43;
- 53;
- 63;
- 73) in proximity to the fastening portion (13;
- 31;
- 41;
- 51;
- 61;
- 71) of the lock (12;
- 30;
- 40;
- 50;
- 60;
- 70) for sliding contact with a withdrawing jig (J) inserted into the housing (10) from a jig inserting direction (JID) so that the withdrawing jig (J) deforms the lock (12;
- 30;
- 40;
- 50;
- 60;
- 70) in the deformation direction (DD) to be disengaged from the terminal fitting (21);
- and
- a distal end (14F;
- 33F;
- 43F;
- 53F;
- 63F;
- 73F) of the jig contact portion (14;
- 33;
- 43;
- 53;
- 63;
- 73) being spaced from a distal end (13F;
- 31F;
- 41F;
- 51F;
- 61F;
- 71F) of the fastening portion (13;
- 31;
- 41;
- 51;
- 61;
- 71) along the jig insertion direction (JID).
A connector, comprising:
- a housing (10) with opposite front and rear ends and cavities (11) extending between the ends, deformation permitting spaces (19) extending rearwardly in the housing (10) substantially adjacent the cavities (11);
- and
- locks (12;
- 30;
- 40;
- 50;
- 60;
- 70) cantilevered forwardly in the housing (10) at locations between the respective cavities (11) and the deformation permitting spaces (19), the locks (12;
- 30;
- 40;
- 50;
- 60;
- 70) being resiliently deformable in a deformation direction (DD) away from the cavities (11) and into the deformation permitting spaces (19), each said lock (12;
- 30;
- 40;
- 50;
- 60;
- 70) having an end, a fastening portion (13;
- 31;
- 41;
- 51;
- 61;
- 71) with a distal end (13F;
- 31F;
- 41F;
- 51F;
- 61F;
- 71F) at an end of the lock (12;
- 30;
- 40;
- 50;
- 60;
- 70), at least one jig contact portion (14;
- 33;
- 43;
- 53;
- 63;
- 73) in proximity to the fastening portion (13;
- 31;
- 41;
- 51;
- 61;
- 71) of the lock (12;
- 30;
- 40;
- 50;
- 60;
- 70), the jig contact portion (14;
- 33;
- 43;
- 53;
- 63;
- 73) having a distal end (14F;
- 33F;
- 43F;
- 53F;
- 63F;
- 73F) spaced rearwardly from the distal end (13F;
- 31F;
