Abstract

<P>PROBLEM TO BE SOLVED: To provide a connector housing for which proper engagement of the connector can be ascertained, and which is simple in structure and of low cost. <P>SOLUTION: The connector housing is composed of a male connector housing 10 and a female connector housing 12 which is to be engaged with the housing 10. A projection 18 formed at one part of an edge a of the male connector housing 10 on the side the female connector housing is inserted, and the height h of this projection from the edge a is established so that the tip of this projection 18 and the rear end of the female connector housing 12 align in the same position, when the female connector housing 12 is inserted into the male connector housing 10 at the regular position. The projection 18 is formed into a hook-shape at the corner part of the male connector housing 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a connector housing capable of confirming whether or not a connector is properly fitted.

  This type of connector housing is disclosed in Patent Document 1, for example. The connector housing includes a female connector housing having a flexible lock arm and a male connector housing having an engaging portion of the flexible lock arm, and holds a lock coupling detecting piece in the male connector housing. A drive unit for the lock coupling detection piece is provided in the flexible lock arm, and when the female connector housing and the male connector housing are completely fitted, a part of the lock coupling detection piece appears outside the male connector housing by the flexible lock arm. It is what has become.

  In this specification, a housing in which a male terminal is incorporated is referred to as a male connector housing, and a housing in which a female terminal is incorporated is referred to as a female connector housing.

Japanese Utility Model Publication No. 4-91083

  However, the connector housing described in Patent Document 1 has a structure in which a lock coupling detection piece is held in the male connector housing, and a drive portion of the lock coupling detection piece needs to be provided in the flexible lock arm. In addition, since the lock coupling detecting piece is a separate part, the cost increases.

  An object of the present invention is to provide a connector housing that can confirm whether or not a connector is correctly fitted, is structurally simple, and is inexpensive.

To achieve this object, the present invention provides a connector housing comprising a male connector housing and a female connector housing fitted to the male connector housing.
A projecting piece is formed on a part of the edge of the male connector housing on the side where the female connector housing is inserted, and the height of the projecting piece from the end edge is set to the male connector housing. When inserted to the position, it is set so that the front end of the protruding piece and the rear end of the female connector housing are aligned at the same position.

  In the present invention, it is preferable that the projecting piece is formed at the corner portion of the male connector housing in the shape of a heel.

  The present invention is more effective when the male connector housing is formed integrally with the case of the electrical junction box for automobiles.

  If the projecting piece as described above is formed, when the male connector housing and the female connector housing are fitted, the mating depends on whether the rear end of the female connector housing is at the same position as the tip of the projecting piece. It is possible to easily confirm whether or not the operation is normally performed (that is, whether or not the male terminal and the female terminal are correctly connected). Further, since the protruding piece may be formed integrally with the male connector housing, it is structurally simple and hardly causes a cost increase.

  Further, when the protruding piece is formed on the hand of the heel, the strength of the protruding piece is improved, and the protruding piece can be prevented from being bent or deformed.

  In addition, a large number of male connector housings are generally integrally formed in the case of the electrical junction box for automobiles. However, if the protruding pieces as described above are formed on these male connector housings, all male connector housings are formed. Thus, it can be easily confirmed whether or not the connector is properly fitted.

Embodiment 1 FIGS. 1 and 2 show an embodiment of the present invention. In the figure, 10 is a male connector housing and 12 is a female connector housing. A male terminal is incorporated in the male connector housing 10 and a female terminal is incorporated in the female connector housing 12. A flexible lock arm 14 is formed in the female connector housing 12, and an engaging portion (not shown) with the flexible lock arm 14 is formed in the male connector housing 10. In this embodiment, the male connector housing 10 is formed integrally with the case 16 of the electrical connection box for automobiles, but the male connector housing 10 may be a single unit. The structure of the female connector housing 12 is the same as the conventional one.

  The feature of this connector housing is that a protruding piece 18 is formed on a part of the edge a of the male connector housing 10 on the side where the female connector housing is inserted. The protruding height h of the protruding piece 18 from the end edge a is such that when the female connector housing 12 is inserted into the male connector housing 10 to the normal position, the tip b of the protruding piece 18 is the rear end c of the female connector housing 12 It is set to align with the same position.

  1A shows a state before the female connector housing 12 is fitted to the male connector housing 10, and FIG. 1B shows a state after the fitting. When the female connector housing 12 is correctly inserted into the male connector housing 10, the rear end c of the female connector housing 12 comes to the same position as the tip of the protruding piece 18 as shown in FIG. Therefore, whether or not the fitting is proper can be easily confirmed by checking whether or not the rear end c of the female connector housing 12 and the tip b of the protruding piece 18 are at the same position.

  The projecting piece 18 is formed at the corner portion of the male connector housing 10 with a scissors hand. This is to increase the strength of the projecting piece 18 and prevent the projecting piece from breaking during transportation or connector fitting.

Embodiment 2 FIGS. 3 and 4 show another embodiment of the present invention. This embodiment is different from the first embodiment in that the projecting piece 18 is formed in a flat plate shape instead of the hand of the heel. When the height h of the projecting piece 18 is low, the strength of the projecting piece does not matter so much, and thus it may be formed in a flat plate shape in this way. Since the configuration other than the above is the same as that of the first embodiment, the same portions are denoted by the same reference numerals and description thereof is omitted.
