[0002]

2. Description of the Related Art As a mounting structure of this type of connector, there is one shown in FIGS.

FIG. 6 shows a mounting structure of a connector 1 in which a connector housing 2 is mounted on a mounting bracket 5 having a narrow width and a large wall thickness. On the outer surface of the connector housing 2, an inserting portion 3 having an L-shaped cross section and a U-shaped plane and a locking protrusion 4 are integrally formed. In addition, an engaging hole 5a that is engaged with and disengaged from the engaging protrusion 4 is formed on the front end side of the mounting bracket 5 into which the inserting portion 3 of the connector housing 2 is inserted.

Then, the insertion portion 3 of the connector housing 2
By locking the locking projection 4 of the connector housing 2 and the engagement hole 5a of the mounting bracket 5 when the mounting bracket 5 is inserted into the tip side of the mounting bracket 5, the mounting state of the mounting bracket 5 and the connector housing 2 is locked. It is like this.

FIG. 7 shows a mounting structure for a connector 1 ', in which a connector housing 2'is mounted on a wide and thin mounting bracket 8. On the outer surface of the connector housing 2 ', a pair of insertion portions 6 and 6 and a locking projection 7 are integrally formed so as to have an L-shaped cross section. In addition, an engaging hole 8a that is engaged with and disengaged from the engaging projection 7 is formed on the tip side of the mounting bracket 8 into which the pair of insertion portions 6 and 6 of the connector housing 2'is inserted.

When the pair of insertion portions 6 and 6 of the connector housing 2'is inserted into the tip side of the mounting bracket 8, the locking projection 7 of the connector housing 2'and the engaging hole 8a of the mounting bracket 8 are inserted. By locking, the mounting state of the mounting bracket 5 and the connector housing 2 is locked.

Incidentally, similar techniques related to the mounting structure of these connectors 1 and 1'are disclosed in Japanese Utility Model Laid-Open No. 4-136885, JP-A-8-222328 and JP-A-2000-825.
No. 44, etc., respectively.

[0008]

However, in the conventional mounting structure of the connectors 1 and 1 ', since the mounting brackets 5 and 8 have different shapes for each vehicle type or manufacturer, parts (connector 1, 1') are formed. 1 ') could not be standardized.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a connector mounting structure in which parts can be shared.

[0010]

According to a first aspect of the present invention, a connector housing is provided with an insertion portion and a locking portion, respectively, and the locking portion is provided on a tip side of a mounting bracket into which the insertion portion of the connector housing is inserted. An engaging portion that is locked / disengaged is provided in the mounting bracket by engaging the engaging portion with the engaging portion when the insertion portion of the connector housing is inserted into the distal end side of the mounting bracket. And a connector mounting structure in which the mounting state of the connector housing is locked, an insertion permitting portion for inserting the tip ends of a plurality of mounting brackets into the insertion portion of the connector housing is provided, and the connector It is characterized in that the housing is provided with a plurality of locking portions that are locked and released from the respective engaging portions of the plurality of mounting brackets.

In this connector mounting structure, the tip end sides of the plurality of mounting brackets can be freely inserted into the insertion allowance portions provided in the insertion portions of the connector housing, and the connector housings can be engaged with each other. Since the plurality of locking portions that are locked and released at the joint portion are provided, the connector can be easily mounted on the plurality of mounting brackets having different shapes without changing the design or adding parts. This allows
Standardization of connectors (components) is achieved.

A second aspect of the present invention is the connector mounting structure according to the first aspect, wherein a mounting bracket of the plurality of locking portions abuts and is not locked to the engaging portion of the mounting bracket. The stop portion is elastically deformable.

In this connector mounting structure, when the insertion portion of the connector housing is inserted into the mounting bracket which is not locked by the elastically deformable locking portion,
Since the locking portion that is elastically deformable comes into contact with the mounting bracket and elastically deforms in the opposite direction to the corresponding contact direction,
The elastic biasing force of the elastically deformed locking portion prevents the tip end side of the mounting bracket and the insertion portion of the connector housing from rattling.

According to a third aspect of the present invention, there is provided the connector mounting structure according to the first aspect, wherein the insertion permitting portion is formed in a stepped shape in accordance with a width dimension of the plurality of mounting brackets. .

In this connector mounting structure, the stepped insertion allowance portion of the insertion portion of the connector housing minimizes the clearance between the insertion portion of the connector housing and the tip side of each mounting bracket. Rattling between the two is easily and reliably prevented.
