Description

Inhibitor Switch < RTI ID = 0.0 >

The present invention relates to an inhibitor switch, and more particularly, to an inhibitor switch having a rigid fastening structure using riveting between a housing and a cover.

The conventional automatic transmission always starts only in the P or N range. This is because a kind of control device is installed for the safety of the driver. Such a control device is generally referred to as an inhibit switch (Inhibit On Switch) And can be visually recognized from the outside.

The inhibitor switch is composed of electric contact plates of various complex circuits inside and is directly connected to the shift lever.

The operating principle is that when the shift lever is moved, the contact position of each electric contact plate is changed so that the energization process is changed, thereby allowing the driver to enter the correct shift position.

That is, when the lever is positioned at a shift range other than the P range or the N range, and the engine is started, the ignition circuit is turned off to prevent the engine from operating. Also, when the shift lever is set to R, the reverse gear as well as the reverse gear are automatically turned on.

However, if the state where the housing and the cover constituting the inhibitor switch are weakened and the vehicle is mounted for a long period of time in the vehicle, the assemblability and robustness of the inhibitor switch can not be maintained under harsh environmental conditions inside the vehicle, This results in a problem that an abnormality in the detection of the speed change signal occurs.

Since the inhibitor switch according to the prior art has a simple housing structure, when an external impact is applied, there is a high possibility that the inhibitor switch is inoperable due to damage of internal components, i.e., movable terminals, as well as breakage of the housing . In addition, the inhibitor switch according to the prior art increases the generation of defective products causing malfunction due to thermal deformation of the terminal lines generated through a single insert injection process, incomplete formation of internal components, burrs, etc. There was a problem.

Particularly, the inhibitor switch according to the prior art is not compatible with the recent automobile technology which requires a compact configuration due to the size of the device through a complicated wiring line.

In addition, when the position of the internal terminal is changed in the assembling process, it is difficult to confirm the current shift range. That is, it is difficult to confirm the positional change of the change gear range in a state where the internal components are assembled through ultrasonic welding or screw assembly, and the manufacturing process efficiency due to complicated processes such as using a separate inspection machine or the like is accompanied with a problem .

On the other hand, a technique related to the inhibitor switch is disclosed in Patent No. 10-0388273 (Patent Document 1).

The patent document 1 discloses a power supply device having a case in which a power supply terminal made of a plurality of metal wirings is provided and a first through hole is formed at one side thereof and a case where the power supply terminal is connected to the first through hole of the case, A signal connector provided on the printed circuit board so as to be rotatable on the upper side of the printed circuit board; an engaging portion which is inserted into the first through hole and is shaft-engaged and provided with a signal connector; A first through hole which is coupled to the opening portion of the case by ultrasonic welding and which is coupled with the coupling portion of the operation plate through the first through hole, And a cover provided at a joint portion between the case and the cover, Characterized in that.

However, in the case of Patent Document 1, since the cover is fastened by ultrasonic welding, the assemblability and robustness of the inhibitor switch described above can not be maintained.

Patent No. 10-0388273

The cover is made of an aluminum material, and is an inhibitor switch in which a bolt fastening portion for protruding from a rim is provided for coupling with an auto transmission.

A seal interposed between a rim portion of the housing and a rim of the cover for airtightness and leakage prevention of the inside and a quadring fitted to a groove portion formed on the upper surface of the rotor.

And the housing is an inhibitor switch made of a plastic material.

The housing and the cover may be an inhibitor switch which is pressed in a wide and expanded form when the protrusion is pressed by applying pressure to the pressing device and the riveting device when they are fastened to each other.

As described above, the inhibitor switch according to the present invention ensures durability reliability through robust design, so that even if the vehicle is mounted for a long period of time in the vehicle, it can maintain the assemblability and robustness, . Further, the fastening of the housing and the cover is more robust than the fastening by the bolt and the ultrasonic welding, and the robustness against the fastening can be kept constant.
