Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shift control lever for an automatic transmission installed in a vehicle, and particularly to an improvement in a shift control lever in which an overdrive release switch is assembled to the shift control lever. Regarding.

(Prior art) In general, vehicles equipped with an automatic transmission with an overdrive mechanism automatically enter the overdrive state when driving at relatively high speeds on a flat road, but depending on the driving conditions. In some cases, it may be necessary to release the overdrive state. For this reason, a mechanism for forcibly canceling the overdrive running state and an overdrive canceling switch for operating this mechanism are provided.

In this case, the overdrive release switch is operated by the driver while the vehicle is running, so the operating section should be located near the driver so that the driver can easily and reliably operate it while driving. It is desirable to install it in a certain position.

Therefore, in order to meet such demands, for example, as disclosed in Japanese Utility Model Application Publication No. 57-118424, a shift operation lever for changing the range of an automatic transmission, which is installed near the driver, has been developed. Focusing on this, we created a hole for installing a switch in the knob of this operation lever, installed an overdrive switch in the hole with its operation part exposed outside, and created a harness whose end was connected to the switch. The wiring is arranged along the operating lever.

However, with the above-mentioned conventional speed change operation lever, since the switch and the harness end are connected by screws, there is a problem that assembly work is time-consuming and workability is poor. Furthermore, if the screws are not sufficiently screwed in, vibrations of the vehicle body may cause the screws to loosen, resulting in poor connection.

(Purpose of the invention) The purpose of the invention is to simplify the assembly work by improving the connection between the switch and the harness end when assembling the overdrive release switch to the gear shift operating lever as described above. The object of the present invention is to prevent connection failures from occurring.

(Structure of the invention) In order to achieve the above object, the structure of the invention is that a cavity for mounting a switch is provided in the operating lever body of an automatic transmission for a vehicle, and the switch is mounted in the cavity so that its operating part is displayed externally. In the gear shift operation lever of an automatic transmission installed in the above-mentioned manner, a juncture terminal is embedded in the operation lever body, and
One end of the junction terminal projects into the switch mounting cavity of the operating lever body, and the other end projects into a harness connector mounting portion provided on the operating lever body. On the other hand, the switch and the harness connector at the end of the harness connected to the switch are each provided with a female terminal that fits into the junction terminal.

By doing this, the switch is inserted into the switch mounting cavity of the operating lever body, the female terminal of the switch is fitted to one end of the junction terminal protruding into the cavity, and the female terminal of the harness connector is inserted into the opening of the operating lever body. By simply fitting the other end of the junction terminal protruding into the harness connector attachment part, the switch and the harness end can be easily and reliably connected by using the operating lever main body as a connector.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.
