Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mounting structure for easily fixing, for example, a connector for wiring in a vehicle to a panel.

[Prior Art] Conventionally, for example, in order to hold a connector for in-vehicle wiring on a body-side panel of an automobile, as shown in FIG. Or panel 4 as shown in FIG.
Is generally indirectly held by inserting a wire bundle 6 connected to the connector 1 into the grommet 5 attached to the through hole.

[Problems to be Solved by the Invention] Among these conventional examples, the former method of fixing with screws or the like requires special parts such as auxiliary metal fittings 2 for fixing the connector, and has poor workability. There is a drawback, and if the space at the mounting location is narrow, there is a problem that mounting becomes difficult or impossible. On the other hand, the latter method using a grommet is based on the fact that the connector is placed in an unstable state,
Disadvantages such as poor waterproofness and airtightness.

An object of the present invention is to solve the above-mentioned problems and to provide a connector mounting structure that can be easily and reliably mounted on a panel using a grommet even in a narrow space.

[Means for Solving the Problems] In the connector mounting structure according to the present invention for achieving the above object, a plurality of connection terminals are housed inside, and a front portion is a fitting portion with a mating housing, A connector housing from which a wire connected to the connection terminal is drawn out from a rear portion is disposed on the inner periphery of the open portion of a grommet made of synthetic rubber or the like and having elasticity, one end being an open portion and the other end being a cylindrical portion. Along with fixing through a plurality of locations of the ring-shaped liner, the wiring is inserted into the cylindrical portion, and the electric wire is fixed in the cylindrical portion to an electric wire fixing portion extending from a part of the connector housing, The grommet is fitted in a panel through hole.

[Operation] In the connector mounting structure having the above configuration, the grommet is fitted into the through hole of the panel, and the connector housing is fixed to the grommet.

[Embodiment] The present invention will be described in detail with reference to FIGS. 1 and 2 based on an embodiment.

FIG. 1 shows an embodiment, in which a connector housing 11 is made of synthetic rubber or the like and is fixed through a plurality of ring-shaped liners 20 in a resilient grommet 12, and the grommet is provided.
The connector housing 11 and the grommet 12 are fixed to the panel 13 by fitting into the through hole 14 of the panel 13. In the open part of the grommet 12, the outer groove 12a and the inner groove 1
2b are provided, and the outer peripheral groove 12a is formed in the through hole 14 of the panel 13.
, And the liner 20 is fitted in the inner peripheral groove 12b.
A mating connector housing 15 is fitted to the front of the connector housing 11, and the connector housings 11, 15
The electric wires 16 and 17 are connected to the connection terminals respectively housed therein, and these electric wires 16 and 17 are drawn out from the rear portions of the connector housings 11 and 15.
Is inserted through the inside of the tubular portion behind.

Reference numeral 15a denotes a locking lever provided on the mating connector housing 15 for locking the connected state of the connector housings 11 and 15, and 15b denotes a rotation fulcrum thereof.
1b is an electric wire fixing portion provided in the connector housing 11, and this electric wire fixing portion 11b is extended into the cylindrical portion of the grommet 12, the electric wire 16 is bound, and even if a tensile force acts on the electric wire 16, The connection terminals in the connector housing 11 are not affected.

Ring-shaped liner 20 made of synthetic resin with good elasticity
Is fixed to the open portion of the grommet 12 by a method such as insert molding or rear assembly, the connector housing 11 is fixed to this liner 20 by means such as forcible fitting, the front portion of the connector housing 11 faces outward, The side connector housing 15 is adapted to be received.

By using the liner 20 in this manner, the work of inserting the connector housing 11 becomes easy, and the grommet 12
By providing a plurality of types of liners 20, it is possible to provide flexibility that a plurality of types of standard connector housings can be used as they are for the grommet 12 of the same standard. The liner 20 has a connector housing 11
It is a matter of course that guide means for guiding the insertion of the connector housing, locking means for fixing the connector housing 11 and the like can be appropriately provided.

Further, the liner 20 has elasticity, and furthermore, as shown in FIG.
By providing a, even if the through-hole 14 of the panel 13 is narrow, it is possible to allow the through-hole by giving a twist.

In this manner, the connector housing 11 is connected via the liner 20.
The grommet 12 incorporating the grommet 12 is pushed into the through hole of the panel 13 so that the grommet 12 and the grommet 12 are fixed to the panel 13.

[Effect of the Invention] As described above, in the connector mounting structure according to the present invention, since the connector housing is fixed to the grommet via the liner, the grommet can be collectively fixed by fitting the grommet to the panel, and the space can be reduced in a narrow space. The connector housing can be easily fixed. Further, since the electric wire is fixed to the electric wire fixing portion extending from the connector housing and inserted into the cylindrical portion of the grommet, even if a tensile force is applied to the electric wire, this tensile force is not applied to the connection terminal.
Furthermore, it can be adopted as it is without changing the normal panel shape, and the cost is low and the workability is good.
