Abstract

A housing for an electrical connecting terminal comprises a body defining a cavity for accommodating the connecting terminal, and a latch member located in the cavity. The latch member extends from a bottom surface of the cavity toward a top surface of the cavity and includes an opening located proximate the bottom surface of the cavity and a locking portion for locking the connecting terminal within the body.

First claim

What is claimed:

1 . A housing for an electrical connecting terminal, comprising:
a body defining a cavity for accommodating the connecting terminal; and a latch member located in the cavity and extending from a bottom surface of the cavity toward a top surface of the cavity, the latch member including:
an opening extending through the latch member; and
a locking portion for locking the connecting terminal within the body.

2 . The housing of claim 1 , wherein the latch member includes an elastic arm inclining in a direction of insertion of the connecting terminal, the opening located proximate the bottom surface of the cavity.

3 . The housing of claim 2 , wherein the latch member includes a pair of elastic arms.

4 . The housing of claim 2 , further comprising a protruding rib positioned in the cavity and below the latch member, the rib limiting the downward deflection of the latch member as the connecting terminal is inserted into the cavity.

5 . The housing of claim 4 , wherein the rib is aligned with the opening in the latch member in the direction of insertion of the connecting terminal.

6 . The housing of claim 1 , further comprising a protruding guide extending along a side of the cavity for guiding the connecting terminal into position within the cavity.

7 . The housing of claim 1 , wherein the locking portion defines a stepped shape formed on an end of the latch member opposite the bottom surface of the cavity.

8 . The housing of claim 1 , wherein the body further defines an unlocking member protruding into the cavity for disengaging a plug-in terminal installed in the connecting terminal.

9 . The housing of claim 8 , wherein the unlocking member includes a surface inclining in a direction of insertion of the connecting terminal.

10 . The housing of claim 1 , wherein:
the latching member forms an angle with the bottom surface of the cavity ranging from 13° to 19°; a length of a force receiving portion of the latch member ranges from 5.3 mm to 7.1 mm; and a thickness of the latch member ranges from 0.7 mm to 0.9 mm.

11 . A connector, comprising:
a connecting terminal; a housing retaining the connecting terminal, the housing defining a cavity and a latch member located in the cavity and extending from a surface of the cavity, the latch member including:
an opening extending through the latch member; and
a locking portion for locking the connecting terminal within the housing; and
a plug-in terminal for selectively engaging with the connecting terminal.

12 . The connector of claim 11 , wherein the latch member includes a pair of elastic arms extending in a direction of insertion of the connecting terminal.

13 . The connector of claim 12 , wherein the body defines an unlocking member arranged at least partially between the pair of elastic arms and adapted to disengage the plug-in terminal from the connecting terminal.

14 . The connector of claim 13 , wherein the unlocking member includes a portion inclining in a direction of insertion of the connecting terminal.

15 . The connector of claim 14 , wherein the connecting terminal includes:
a body; two crimping portions; and a tongue, the tongue having an upwardly bent end defining a release portion, the release portion oriented adjacent the inclined portion of the unlocking member with the connecting terminal installed in the housing.

16 . The housing of claim 12 , further comprising a pair of ribs positioned in the cavity and below each of the elastic arms, the ribs defining a face inclining in a direction opposite to that of the elastic arms.

17 . The connector of claim 11 , wherein the locking portion has a stepped shape formed on a free end of the latch member.

18 . The connector of claim 11 , further comprising a pair of guides extending along each side of the cavity for guiding the connecting terminal into position in the cavity during insertion.

19 . The connector of claim 11 , wherein the opening is centered over a thickness of the latch member and is partially defined by a bottom surface of the cavity.

20 . The connector of claim 11 , wherein:
the latching member forms an angle with the bottom surface of the cavity ranging from 18° to 15°; a length of a force receiving portion of the latch member ranges from 6.0 mm to 6.5 mm; and a thickness of the latch member ranges from 0.75 mm to 0.88 mm.
