Sealed electrical connector

1. Electrical connector comprising

an insulative housing having a front mating face and a plurality of terminal accommodating chambers with an open rear end for the insertion of the respective terminal,

a grommet-type seal formed with a plurality of cable passages in correspondence with the chambers and arranged in said housing at the rear end of the chambers,

a grid attached within the housing at the rear side of the seal for maintaining the seal in the housing and for guiding cables, said grid having a plurality of passages in correspondence with the passages of the seal, and

a closing member mounted at the rear side of the grid for selectively closing the passage to a first predetermined group of chambers, said closing member comprising a plate, which is formed with through-holes in correspondence with a second predetermined group of chambers, said second group being complementary to the first group,

characterized in that the closing member further comprises at least one plug projecting from the plate in correspondence with the first group of chambers, said plugs being provided to be inserted in the respective passages of the seal, and thus sealingly close said passages.

2. Electrical connector as claimed in claim 1 , characterized in that it further comprises first snap-fit means for fixing the closing member within the housing.

3. Electrical connector as claimed in claim 1 , characterized in that the closing member is made integral of a plastic material.

4. Electrical connector as claimed in claim 1 , characterized in that the closing member is made integral by moulding and stamping.

5. Electrical connector as claimed in claim 1 , characterized in that the plugs of the closing member are made as fingers, all of which having substantially the same length and substantially perpendicularly projecting from the plate in the same axial direction.

6. Electrical connector as claimed in claim 5 , characterized in that the plugs are made as substantially cylindrical fingers.

7. Intermediate standard closing member for manufacturing a closing member of an electrical connector as claimed in claim 5 by a process for manufacturing the closing member of the electrical connector comprising the following successive steps:

manufacturing an intermediate standard closing member, which comprises a solid plate and a number of projecting plugs corresponding to all the chambers of the housing, and

stamping said intermediate standard closing member in order to selectively remove plugs and form through-holes in correspondence with the second predetermined group of chambers to be opened for a respective connector configuration, characterized in that it comprises a solid plate and an array of fingers, all of said fingers having substantially the same length and substantially perpendicularly projecting from the plate in the same direction.

8. Electrical connector as claimed in claim 1 , characterized in that the grid and the housing are provided with second snap-fit means for fixing the grid within the housing.

9. Process for manufacturing the closing member of an electrical connector as claimed in claim 1 , comprising the following successive steps:

manufacturing an intermediate standard closing member, which comprises a solid plate and a number of projecting plugs corresponding to all the chambers of the housing, and

stamping said intermediate standard closing member in order to selectively remove plugs and form through-holes in correspondence with the second predetermined group of chambers to be opened for a respective connector configuration.

10. Process as claimed in claim 9 , wherein the step of manufacturing the intermediate standard closing member is made by integral moulding from a plastic material.

11. Electrical connector as claimed in claim 1 wherein a first one of said through-holes of said closing member is aligned with more than one of said chambers.

12. An electrical connector comprising:

a housing having a plurality of terminal accommodating chambers;

a grommet-type seal arranged in the housing at rear ends of the chambers, wherein the seal comprises a plurality of passages in correspondence with the chambers;

a grid attached to the housing and located at a rear side of the seal, wherein the grid maintains the seal in the housing and is adapted to guide cables, wherein the grid comprises a plurality of passages in correspondence with the passages of the seal; and

a closing member located at a rear side of the grid, wherein the closing member closes passage to a first predetermined group of the chambers, wherein the closing member comprising a plate and at least one plug projecting from the plate, wherein the plate comprises through-holes in correspondence with a second predetermined group of chambers, wherein a first one of the through-holes is aligned with more than one of the chambers, wherein the at least one plug is in correspondence with the first group of chambers, and wherein the at least one plug is located in respective passages of the seal and sealingly close the respective passages of the seal.

13. A method comprising:

providing a housing having a plurality of terminal accommodating chambers;

locating a grommet-type seal in the housing at rear ends of the chambers, wherein the seal comprises a plurality of passages in correspondence with the chambers;

connecting a grid to the housing located at a rear side of the seal, wherein the grid maintains the seal in the housing and is adapted to guide cables, wherein the grid comprises a plurality of passages in correspondence with the passages of the seal; and

connecting a closing member to the grid located at a rear side of the grid, wherein the closing member closes passage to a first predetermined group of the chambers, wherein the closing member comprising a plate and at least one plug projecting from the plate, wherein the plate comprises through-holes in correspondence with a second predetermined group of chambers, wherein a first one of the through-holes is aligned with more than one of the chambers, wherein the at least one plug is in correspondence with the first group of chambers, and wherein the at least one plug is located in respective passages of the seal and sealingly close the respective passages of the seal.

14. A method as in claim 13 further comprising manufacturing the closing member comprising:

manufacturing an intermediate standard closing member, which comprises a solid plate and a number of projecting plugs corresponding to all the chambers of the housing, and

stamping the intermediate standard closing member in order to selectively remove plugs and form the through-holes in correspondence with the second predetermined group of chambers to be opened for a respective connector configuration.
