Description

  The present invention relates to a connector fitting structure related to fitting between connectors.

  As a fitting structure of connectors that are fitted on one side of a wall having a through hole, for example, a structure disclosed in Patent Document 1 below is known. This fitting structure has been proposed as relating to the structure of an automobile door. In Patent Document 1 below, a remote control mirror attached to the outer panel, a mirror connector for controlling the remote control mirror, an inner panel having a through hole, and an inner panel (vehicle compartment side) are routed. A wire harness for doors and a harness connector provided at a terminal of the harness are disclosed.

  The harness connector is inserted into the inner panel from the inner side to the outer side through the through hole, and then fitted with the mirror connector, whereby the electrical connection is completed (see Patent Document 1 below). Also discloses an example in which the mirror connector is inserted into the inner panel and fitted with the harness connector).

  The through hole of the inner panel is formed to have a size that allows the harness connector or the mirror connector to be inserted. The reason why the through hole is formed small is that waterproofness is taken into consideration.

Japanese Patent Laid-Open No. 11-32485

  By the way, the above-described prior art has the following problems with the recent high functionality. In other words, if the connector is made larger in order to meet the desire to increase the number of connector poles (the number of terminals), it is necessary to increase the size of the through-holes at the same time. It has a problem that it will come.

  In some cases, it may not be possible to change the size of the through-hole, and in this case, it is not possible to increase the number of poles, and it is also impossible to make an electrical connection. Has a point.

  When increasing the number of poles, for example, if there are two connectors for harness and two for mirror, respectively, it is considered that it is not necessary to change the size of the through hole, but the fitting work between the connectors Since (connecting work) increases from once to twice, this has an effect on workability. In addition, if two harness connectors and two mirror connectors are used, the number of components will increase.

  In addition, depending on the vehicle type and grade, the conventional harness connector and mirror connector may be fitted together. There are problems in that the two patterns for fitting together the connectors having a large number must be properly used, resulting in complicated parts management and increased man-hours.

  The present invention has been made in view of the above circumstances, and even if the connector has a large number of poles and the size of the through hole to be inserted is small, the connectors are fitted to each other on one side of the through hole. Connector fitting structure that can be used, connector fitting structure that can be used properly according to the number of poles, and further, it is easy to manage parts without increasing the number of mating operations and the number of parts It is an object to provide a possible connector fitting structure.

The connector fitting structure of the present invention according to claim 1, which has been made to solve the above-mentioned problems, is a structure relating to fitting of connectors, wherein the connector includes a first connector and / or a second connector, and a third connector. A connector that fits on one side of a wall having a through-hole, the first connector including a first connector housing having a size smaller than the size of the through-hole, and the through-hole The second connector is provided with a second connector housing having a size smaller than the size of the through-hole, similarly to the first connector, and is inserted through the wall from the other side to the one side. is intended to be inserted into one side from the other side of the wall through the through-hole, the third connector, the third connector formed with a larger size than the size of the through-hole And Ujingu, the third connector located inside the housing, and a connector fitting portion for accommodating a fourth connector is a state that is a combination of the first connector and the second connector is formed in the connector fitting portion, A positioning rib protruding inward, and in a state in which the fourth connector is fitted to the third connector, the positioning rib is located on a side portion of the fourth connector, and the connector fitting In the state in which the portion holds the corner of the fourth connector and the first connector or the second connector is fitted to the third connector, the connector fitting portion and the positioning ribs of the first connector The corner portion or the corner portion of the second connector is held .

  According to the present invention having such a feature, when the first connector and the second connector are inserted from the other side of the wall to the one side through the through hole, the first connector and the second connector are inserted on one side of the wall. If the first connector and the second connector in combination and the combined state are fitted to the third connector, the size of the through-hole to be inserted is small even if the connector has a large number of poles. In addition, the connectors can be fitted to each other on one side of the through hole without changing the size of the through hole to be inserted. In addition, the electrical connection can be completed by a single fitting operation.

  Further, according to the present invention, when the first connector or the second connector is inserted from the other side of the wall to the one side through the through hole, the first connector or the second connector is fitted to the third connector alone. If they are combined, it is possible to use them in accordance with the number of poles, together with the case of fitting the connectors having a large number of poles. By making it possible to use properly according to the number of poles, the present invention makes it easy to manage the parts and suppress the increase in the number of parts.

  According to the present invention having such a feature, the positioning rib has a connector positioning function both in a combined state and in a single state.

  In addition, the connector fitting structure of the present invention has the following characteristics. That is, in the connector fitting structure of the present invention, with respect to the combination, the first connector housing and the second connector housing are orthogonal to the fitting direction of the first connector, the second connector, and the third connector. It has the union structure part which is made to slide and unite in the direction to do. According to such a feature, it is possible to make it difficult to cause a positional shift between the first connector and the second connector in a combined state when the third connector is fitted or after the fitting.

  According to the first aspect of the present invention, even if the connector has a large number of poles and the size of the through-hole to be inserted is small and the size of the through-hole to be inserted is not changed, it can be penetrated. There is an effect that the connectors can be fitted on one side of the hole. Further, according to the present invention, there is an effect that even if the connector has a large number of poles and the size of the through-hole to be inserted is small, the number of fitting operations can be prevented from increasing. Furthermore, according to this invention, there exists an effect that it can be used properly according to the number of poles. Furthermore, according to the present invention, it is possible to easily manage components and to suppress increase in the number of components by properly using them according to the number of poles.

According to the first aspect of the present invention, by having the positioning rib, there is an effect that the connector can be positioned both in the combined state and in the single state.
