Abstract

DC60 (19/01/47) The purpose of this invention is to provide a connector housing that can prevent the terminal chamber from being opened. The incorrect metal connector housing 1 comprises one 20-unit connector chamber and one 21-unit mark. The 20-unit connector chamber accepts a 3-unit male connector. Wire 2 is attached to the 3-unit male connector. Mark 6 is formed on the outer surface 5a of wire 2. The color of mark 6 of wire 1 is the first color R. The color of mark 6 of the other wire 2 is the second color G. The first color R is different from the second color G. Mark 21 corresponds to each 20-unit connector chamber. The color of mark 21 is the first color R, which is the same as the color of mark 6 of wire 1. The color of mark 21 is the second color G, which is the same as the color of mark 6 of the other wire 2. By forming mark 21 in the same color as mark 6 of wire 2, it is attached to the 3-unit male connector that will be inserted. In a terminal housing corresponding to mark 21, the mark 21 provides identification for a male connector 3 to be accepted by the terminal housing corresponding to mark 21. The purpose of this invention is to provide a connector housing that can prevent the terminal housing from being accepted. The incorrect metal connector housing 1 comprises one 20-unit connector chamber and one 21-unit mark. The 20-unit connector chamber accepts a 3-unit male connector. Wire 2 is attached to the 3-unit male connector. Mark 6 is formed on the outer surface 5a of wire 2. The color of mark 6 of wire 1 is the first color R. The color of mark 6 of the other wire 2 is the second color G. The first color R is different from the second color G. Mark 21 corresponds to each 20-unit connector chamber. The color of mark 21 is the first color R, which is the same as the color of mark 6 of wire 1. The color of mark 21 is the second color G, which is the same as the color of mark 6 of the other wire 2. By forming mark 21 in the same color as mark 6 of wire 2, it is attached to the 3-unit male connector that will be inserted. In the terminal receiving chamber 20, which is matched to mark 21, mark 21 provides identification for the 3-pin male connector to be accepted by the terminal receiving chamber 20, which is matched to mark 21.

Claims (9)

1. The connector housing comprises: several terminal chambers for receiving metal connectors; where markings are provided on the outer surface of the connector housing in a matching manner to each terminal chamber, providing identification for the specific metal connector to be accepted by that matching terminal chamber. 2. The connector housing as defined in Claim 1, where the terminal chamber is formed with a number of partitions, the opening of the terminal chamber is enclosed by such partitions, and a mark is provided on the surface of one of the partitions enclosing the opening of the terminal chamber, such surface being flush with the opening. 3. The connector housing as defined in Claim 1, where the terminal chamber is formed with a number of partitions, the opening of the terminal chamber is enclosed by a number of partitions, and markings are provided on the ends near the openings of the inner surface of the terminal chamber. 4. The method of marking the connector housing involves the following steps: providing a connector housing with a number of terminal chambers for receiving metal connectors; forming matching markings on each terminal chamber to identify the designated metal connectors to be received by the matching terminal chambers; and performing this marking process by injecting a specified volume of coloring agent into the connector housing for surface coating. 5. The method of marking the connector housing as specified in Claim 4, whereby the procedure for providing a connector housing with a certain number of terminal chambers is accomplished by constructing the terminal chambers with a certain number of partitions, enclosing the terminal chamber openings with these partitions, and the marking procedure is accomplished by injecting a specified volume of coloring agent onto the surface of one of the partitions enclosing the terminal chamber openings, such surface being flush with the said opening. 6. The method of marking the connector housing as specified in Claim 4, whereby the procedure for providing a connector housing with a certain number of terminal chambers is accomplished by constructing the terminal chamber with a certain number of partitions, thus enclosing the opening of the terminal chamber with the partitions, and the marking procedure is accomplished by injecting a specified amount of coloring agent into the end near the opening of the inner surface of the terminal chamber. 7. The method of inserting the metal connector into the connector housing consists of the following steps: forming a connector chamber with several partitions surrounding the connector chamber opening; making several markings, each mark placed at each connector chamber, identifying the designated connector to be accepted by the matching connector chamber corresponding to the markings; and inserting the designated metal connector into the matching connector chamber corresponding to the markings through the opening. 8. The method of inserting the metal connector into the connector housing as specified in Claim 7, where a mark is provided on the surface that is level with the opening of the connector chamber of one of the partitions surrounding the opening. 9. The method of inserting the metal connector into the connector housing as specified in Claim 7, where markings are provided at the end near the opening of the inner surface of the connector housing.
