Electrical connector with two types of connector terminals and a spacer inserted into a housing
In a connector, a spacer includes lock parts and regulation parts. Each of the lock parts locks a first terminal in a first terminal receiving slot after the first terminal is inserted into a proper position in the first terminal receiving slot. Each of the regulation parts regulates deformation of a second lance toward a release position when the second lance is located in a lock position in which the second lance locks a second terminal in a second terminal receiving slot after the second terminal is inserted into a proper position in the second terminal receiving slot.
1. A connector comprising:
a first terminal;
a second terminal different from the first terminal;
a housing that includes
a first terminal receiving slot extending along a terminal insertion direction and configured to have the first terminal inserted therein,
a second terminal receiving slot extending along the terminal insertion direction and configured to have the second terminal inserted therein,
a lance provided on a wall surface of the second terminal receiving slot and being elastically deformable between a lock position and a release position, the lock position being a position in which the lance locks the second terminal in the second terminal receiving slot after the second terminal enters the second terminal receiving slot and is inserted into a proper position, the release position being a position retreated from the second terminal receiving slot, and
an installation space part formed along an assembly direction intersecting the terminal insertion direction; and
a spacer configured to be incorporated, during assembly, into the installation space part by being moved in the assembly direction, wherein
the spacer includes
a lock part configured to lock the first terminal in the first terminal receiving slot after the first terminal is inserted into a proper position in the first terminal receiving slot, and
a regulation part configured to make contact from below with the lance and to prevent the lance from deforming toward the release position when the lance is located in the lock position in which the lance locks the second terminal in the second terminal receiving slot after the second terminal is inserted into a proper position in the second terminal receiving slot.
2. The connector according to claim 1 , wherein
the first terminal has a first recess located between a front end portion thereof and a base end portion thereof in the terminal insertion direction and recessed from a circumferential surface of the front end portion,
the lock part of the spacer is capable of interlocking with the first recess,
when the spacer is moved to the installation space part with the first terminal inserted into the proper position, the first recess and the lock part interlock with each other, and the spacer is disposed in a normal position, and
when the spacer is moved to the installation space part with the first terminal not inserted into the proper position, the first recess and the lock part do not interlock with each other, and the spacer is disposed in a position deviated from the normal position.
3. The connector according to claim 1 , wherein
the second terminal has a recess located between a front end portion thereof and a base end portion thereof in the terminal insertion direction and recessed from a circumferential surface of the front end portion,
the lance is capable of interlocking with the recess,
when the spacer is moved to the installation space part with the second terminal inserted into the proper position, the recess and the lance interlock with each other, and the spacer is disposed in a normal position, and
when the spacer is moved to the installation space part with the second terminal not inserted into the proper position, the recess and the lance do not interlock with each other, and the spacer is disposed in a position deviated from the normal position.
4. The connector according to claim 2 , wherein
the second terminal has a second recess located between a front end portion thereof and a base end portion thereof in the terminal insertion direction and recessed from a circumferential surface of the front end portion,
the lance is capable of interlocking with the second recess,
when the spacer is moved to the installation space part with the second terminal inserted into the proper position, the second recess and the lance interlock with each other, and the spacer is disposed in a normal position, and
when the spacer is moved to the installation space part with the second terminal not inserted into the proper position, the second recess and the lance do not interlock with each other, and the spacer is disposed in a position deviated from the normal position.
5. The connector according to claim 3 , wherein
the second terminal includes upper second terminals positioned in an upper part in the assembly direction and lower second terminals positioned in a lower part in the assembly direction,
the upper second terminals and the lower second terminals are aligned in a terminal alignment direction intersecting the terminal insertion direction and the assembly direction,
each of the lower second terminals is arranged between adjacent two of the upper second terminals in the terminal alignment direction,
the regulation part includes first regulation parts and second regulation parts, the first regulation parts being configured to prevent of the lance that locks one of the upper second terminals in the second terminal receiving slot from deforming, the second regulation parts being configured to prevent of the lance that locks one of the lower second terminals in the second terminal receiving slot from deforming, and
the first regulation parts and the second regulation parts are alternately arranged in the terminal alignment direction.
6. The connector according to claim 4 , wherein
the second terminal includes upper second terminals positioned in an upper part in the assembly direction and lower second terminals positioned in a lower part in the assembly direction,
the upper second terminals and the lower second terminals are aligned in a terminal alignment direction intersecting the terminal insertion direction and the assembly direction,
each of the lower second terminals is arranged between adjacent two of the upper second terminals in the terminal alignment direction,
the regulation part includes first regulation parts and second regulation parts, the first regulation parts being configured to prevent of the lance that locks one of the upper second terminals in the second terminal receiving slot from deforming, the second regulation parts being configured to prevent of the lance that locks one of the lower second terminals in the second terminal receiving slot from deforming, and
the first regulation parts and the second regulation parts are alternately arranged in the terminal alignment direction.
