[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector which is frequently used for internal wiring of a vehicle, an outboard motor, and the like.

[0002]

2. Description of the Related Art In recent years, in order to send electric signals from various electric components (controllers, sensors, solenoids, injection valves, etc.) arranged in an engine room of an automobile or the like to a plurality of meters or the like in a vehicle compartment, a plurality of electric signals are required. A harness made of bundled wires is used. This harness is bundled in the middle, and is distributed in a branching shape toward the tip,
The connector is connected to a connector body corresponding to the number of poles (see FIGS. 3 to 5).

In order to pass such a connector from, for example, the engine room to the vehicle interior, a small hole 54 is first made in a dash panel 53 separating the engine room and the vehicle interior as shown in FIG. , The connector 51 is passed through the vehicle interior. Since the dash panel 53 separates the engine room from the vehicle interior, the diameter of the small hole 54 is made as small as possible, so that noise in the engine room, hot air generated from the engine, etc. are directly transmitted to the vehicle interior. Made to prevent leaks.

[0004]

On the other hand, in recent automobiles and the like, an increase in the number of electrical components and the like due to improvement in maneuverability and high-level thinking of consumers is noticeable. For this reason, the number of connectors connected to the harness is increasing. Also, as the number of poles increases, the shape also increases.

[0005] In the engine room of a vehicle, many components such as machinery and pipes are generally arranged in a complicated manner. Further, depending on the type of the vehicle, parts such as instruments and pipes may be placed on the front surface of the small hole of the dash panel as an obstacle due to design reasons. Therefore, in order for the worker to pass the connector through the small hole of the dash panel, the worker performs the work by inserting a finger or the like into a narrow space formed between the components arranged in a complicated manner and bypassing the obstacle described above. ing. Such operations are repeated each time according to the number of connector bodies.
In addition, if the connectors are different, it is necessary to pass the connectors one by one through a small hole in the dash panel, which is extremely troublesome. Further, since such work is usually performed on an assembly line of an automobile, there is a problem that workability is extremely poor.

[0006]

The object of the present invention is to improve the inconvenience of the above-mentioned prior art, and to provide a connector with good mountability, in which a plurality of connector bodies can be relatively easily passed or wired together with a harness in a meandering narrow place. The purpose is to provide.

[0007]

According to the present invention, a harness is provided.
Multiple cable anchors to secure some cable ends
And insertion of part or all of the other cables of the harness
A connector body provided with a concave portion having a concave groove shape that allows the connector body. And this connector body is formed into a square cross section
At the same time, the groove-shaped groove is formed at a corner of the connector body.
A recessed portion, and the plurality of
Of you arranged a cable fixation portion, and employs a configuration that. This aims to achieve the above-mentioned object.

[0008]

[Operation] A plurality of connectors are inserted into the concave portions of the connector body.
Can be linked strung like through the harness cable described above by the action of the groove-like recess, thereby, it is possible not only to bundle harness itself engageable without using a particular bundle member Because of the flexibility as a whole, it is possible to quickly and smoothly mount equipment in narrow, winding places.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a front view of a connector body 1 according to the present invention. In FIG. 1, the connector main body 1 has a cable fixing portion 1A for fixing an end of a part of a plurality of cables constituting a harness 52.
And a concave groove-shaped recessed portion 5 for inserting and holding a part or all of the other cables constituting the above-mentioned harness. This recess 5 is cut off as shown in FIG.
The upper left part of the connector body 1 formed in a square
Section) . To describe this in more detail, the concave portion 5 is formed of a U-shaped (or concave-shaped) groove having an open upper portion. This concave-shaped recess 5
Are provided along the cable insertion direction into the cable fixing portion 1A described above. At both ends of an opening formed in the upper left portion of the groove in FIG. 1, a key portion 6 is provided as a ridge for locking a harness 52 as a cable bundle. Similarly, the other connector main body 1 is also provided with a key portion (protrusion) 6, which is an equivalent engagement means, thereby forming a connector.

Next, a method of using the connector will be described with reference to FIG. First, the connector body 1 is configured such that the recess 5 of the connector body 1 is connected to the harness 5 of another connector body 7.
2 is engaged. Here, a conventionally known connector main body is provided as the connector main body 7. Further, the connector body 2 is similarly connected to the harness 5 of the other connector bodies 7, 1.
2 is engaged. Although only three connector bodies are shown in FIG. 2, three or more connectors can be connected if necessary. The connectors connected in a plural number in this manner are connected in a daisy chain, so that flexibility is increased. Therefore, only the top connector body 7 connected in a daisy chain bypasses obstacles such as the above-mentioned instruments and pipes in the engine room, and the dash panel 5 is connected.
By passing the small connector 54 through the small hole 54, the other connector main bodies 1 and 2 are also pulled together, so that a narrow space or the like due to an obstacle can be quickly and reliably bypassed.

The connectors connected in this manner can be passed through the small holes 54 of the dash panel 53 several times at a time because of the daisy chain connection. Then, the respective connector bodies that have passed through the small holes 54 of the dash panel 53 are disconnected and connected to their respective predetermined locations. In addition, extra connectors can be connected and fixed. Here, as the engagement means for engaging the harness of the connector body in the present embodiment, a groove having a U-shaped cross section is formed, but the shape is not necessarily limited to this shape as long as the shape can engage the harness. There is no. Furthermore, the connector of the present embodiment is also effective when passing through a gap between an engine and electrical components that are complicatedly arranged in a narrow place such as a motorcycle or an outboard motor.

[0013]

[Effect of the Invention] In the present invention, since several connectors are connected to each other via a cable to form a daisy chain, a gap between various components and the like which are arranged in a complicated manner in the engine room is harnessed. Can be relatively easily detoured together, and because they are connected, they can pass through several small holes in the dash panel at a time, making it possible to perform harness installation work quickly and efficiently. As a result, For example, it is possible to provide an unprecedented practical connector capable of improving the efficiency of a process of mounting electrical components on a vehicle assembly line.
