Description

Terminal of Switch for Preventing Water Inflow from Outside and Inhibitor Switch Using Thereof}

The present invention relates to a terminal of a switch and an inhibitor switch using the same, and more particularly, by forming a switch terminal by modifying a metal wiring constituting the terminal of the switch, foreign substances such as moisture from the outside of the switch into the switch. It relates to a switch terminal and an inhibitor switch using the same for suppressing the occurrence of a switch malfunction.

Terminals provided in the switch are typically provided on one side of the switch to connect with other components, such as connectors, so as to be connected to the switch and transmit signals.

Typically, the terminal is a metal wiring having a plate-like shape extending in the longitudinal direction, and the plate-shaped terminal is press-processed between the frame and the frame to be integrally injection molded into the case, or connected to the terminal of the switch case. It is provided to be connected to the outside on the inside.

On the other hand, when the switch is located in a space that is not in contact with foreign matters such as moisture or water, its configuration is not limited, but when exposed to the outside, foreign matter such as liquid from the outside flows into the switch and the Malfunctions may be caused.

As an example of such a switch located externally, there is an inhibitor switch shown in FIG.

The inhibitor switch outputs a shift signal so that the driver can recognize the position of the shift lever in the cluster.

The inhibitor switch for outputting the shift signal includes a P (Parking) stage for parking, an N (Neutral) stage for maintaining an idling state, an R (Reverse) stage for reversing, and a Drive stage for driving a vehicle, It is connected to the control lever of the automatic transmission composed of 2, L (low) stages.

Here, the inhibitor switch is positioned to be exposed to the upper portion of the mission cover so as to be connected to the mission shaft of the vehicle. As shown in FIG. 2, the connector and the outer shape of the connector are secondary after injecting the primary insert with the terminal. By insert injection, foreign substances such as liquid cannot be introduced into the inhibitor from the outside.

These inhibitor switches are kept tight so as to be completely disconnected from the outside through the above-described insert injection, and are only connected to other parts through terminals provided in the connector portion of the inhibitor switch.

However, in the conventional inhibitor switch, when some deformation occurs in the primary injection product in which the injection is completed by heat generated during the injection of the secondary insert during the manufacturing process, water or water may be caused by a minute gap between the terminal and the injection product. Foreign matter may enter and cause contact fault of inhibitor switch.

In particular, since the connector constituting the inhibitor switch is usually made of a polymer resin material and the terminal is made of a metal, the inhibitor switch may be operated for a long time even if the inhibitor switch is not deformed during the injection of the second insert. When used, a very small amount of water continuously flows into the inside of the inhibitor switch along the interface of the polymer resin and the terminal, that is, the surface of the terminal, which may cause the inhibitor switch to malfunction.

The present invention provides a terminal for preventing the introduction of foreign matter such as water and / or water along one side of the terminal into the switch including the terminal.

In addition, the present invention provides an inhibitor switch including a terminal for preventing the foreign substance from flowing in.

The present invention is a switch terminal consisting of at least one metal wiring,

The metal wiring has a plate-like shape extending in the longitudinal direction, and provides a switch terminal including a protrusion projecting to the left, right or left / right with respect to the longitudinal direction is formed.

Here, at least one forging may be further formed on the surface of the metal wiring.

The present invention also provides an inhibitor switch comprising the switch terminal.

The present invention prevents foreign substances such as water and / or water from flowing into the switch along one side of the terminal.

In one aspect, the present invention is a switch terminal consisting of at least one metal wiring, wherein the metal wiring has a plate-like shape extending in the longitudinal direction, protrudes to the left, right or left / right with respect to the longitudinal direction It provides a switch terminal comprising the formed protrusions.

Here, at least one forging may be further formed on the surface of the metal wiring.

In another aspect, the present invention provides an inhibitor switch including the switch terminal.

The terminal according to the present invention is provided in the switch and is connected to another external component, for example, a connector, to transmit a signal according to the operation of the switch, and is not particularly limited as long as it is a conventional terminal in the art having this purpose. .

Here, the terminal is composed of at least one metal wiring, preferably a plurality of metal wirings having a plate shape extending in the longitudinal direction.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. However, the following description is only for the purpose of specifically describing the present invention, and the scope of the present invention is not limited by the following description.

1 is a perspective view of an inhibitor switch, FIG. 2 shows a primary and secondary insert injection for manufacturing the inhibitor switch, and FIG. 3 is a form of a terminal and terminal of an inhibitor switch comprising a terminal according to the invention. 4 is a diagram showing a terminal according to the present invention.

As shown in Figures 1 to 4, the terminal 14 according to the present invention has a plate-like shape extending in the longitudinal direction, protruding to the left, right or left / right relative to the longitudinal direction (16) ) Is formed.

Here, the terminal 14 may be applied to and used in home, vehicle, and / or industrial switches, but is not particularly limited to the above-described use.

On the other hand, for easy description of the terminal 14 according to the present invention, the present invention will be described with reference to the terminal 14 provided in the inhibitor switch 10 as an example.

The inhibitor switch 10 according to the present invention outputs a shift signal so that a driver can recognize a position of the shift lever in a cluster.

The inhibitor switch 10 is preferably manufactured by injecting the first insert into the frame together with the terminal 14 and then inserting the connector insert 12 and the outer shape into the second insert in order to provide airtightness to the switch.

The inhibitor switch 10 according to the present invention is connected to the contact portion 20 and at least one terminal for generating a signal in contact with the switch operation and is connected to the contact portion 20, the signal according to the switch operation Terminal 14 for conveying is integrally formed through the insert injection.

At this time, the contact portion 20 is positioned so that the airtightness is maintained inside the inhibitor switch 10, the terminal 14 is another external component, for example, a connector (not shown), etc., the connector inserting portion 12 It is positioned to be exposed to the outside in the connector insertion portion 12 to be inserted into and connected to the.

Moisture, particularly a very small amount of water, may flow through the contact surface between the two surfaces. If moisture enters the inhibitor switch 10 for a long time, moisture may flow along the surface of the plate-shaped terminal 14. By moving to the terminal of the contact portion 20 may cause a malfunction of the inhibitor switch 10.

Accordingly, the terminal 14 according to the present invention has a protrusion 16 protruding to the left, right, or left / right side with respect to the longitudinal direction of the plate-like shape extending in the longitudinal direction to overcome the above-mentioned problem. As a result, the movement of the water is suppressed or the movement path is expanded to prevent the water flowing along the surface of the terminal 14 from reaching the contact portion 20 of the inhibitor switch 10.

If necessary, the terminal 14 according to the present invention may be further formed with a forging 18 on the surface of the metal wiring.

In the forging 18, the terminal 14 protrudes upwards or downwards from the surface of the metal wiring to suppress the movement of moisture or extend the movement path to inhibit the moisture flowing in along the surface of the terminal 14. Do not reach the contact portion 20 of (10).
