Description

Improved structure of triggering combination of switch device

The invention relates to an improved combination structure of a switch device; in particular, a switch device includes a connection seat and a trigger body, and cooperates with the elastic deformation zone of the trigger body to generate accumulated or released energy in response to loading and unloading operations, allowing personnel to The inventor who simply inserts and detaches the connecting seat laterally by combining the simple operation of the trigger body.

Used in motors, electronics, and automatic control systems to allow operators to operate switches or switch indicating devices that operate on or off the power supply. For example, DE 4408366 A1 provides a typical embodiment. This type of switch device includes an operation part configured with a push or rotary switch and a body (or collectively referred to as an operation part body) for accommodating the operation part; the operation part body passes through a connection base provided with a combination hole, and the hole wall of the combination hole of the connection base is formed There are a plurality of inserts. Corresponding to the inserts, a groove is formed in the operation part body. The operation part body passes through a combination hole, and the insert fits the groove, so that the operation part body and the connection seat are combined. The bottom of the connection base is provided with a buckling part for buckling a plurality of parallel wiring modules; the wiring module is equipped with electric contacts and wiring components for connecting electric wires, and the wiring component is controlled by the operating part to control the electrical properties. Open or path status of the contact.

In order to make the combination of the operation part body and the connecting seat not to be easily disengaged or to securely install the locking function, the conventional art has disclosed many forms of locking structures. For example, Japanese patents such as JP 2000-340062 A, CN 2821833 Y, "Quick Connection Locking Mechanism of Knob Switch", etc., provide feasible embodiments. They are set on the connector A rotating plate (and an arm protruding from the rotating plate); the rotating plate can control the locking combination of the operating body and the connection base or unlock and disengage (or called dismounting). The embodiment is not provided with a special safety protection mechanism, so in the case of human negligence or accidental touch, the turning plate or arm can be turned to the unlocked position, which affects the stable combination state of the operation body and the connection seat, or causes operation When the main body and the connector are disengaged.

In order to improve the above-mentioned problems and use cases, the old method also discloses a technical structure of applying a rotation type to obtain a lock combination or uninstall. The connecting base of the technique is provided with a combination hole and a slot seat located around the combination hole, and an annular rotating plate is axially (or longitudinally) inserted into the slot seat; the annular rotating plate projects a convex arm and is formed in the convex The embedded part on the arm enables the connecting seat to be provided with a shell part and a blocking part formed in the shell part correspondingly. It is assumed that when the convex arm is located inside the shell portion of the connecting seat, the insert portion is fitted on the blocking portion, and the annular rotating plate cannot be rotated to form a locked state.

When a person wants to release the locked state, operate a flat-blade screwdriver or similar tool to insert the convex arm and the shell part to push the convex arm, forcing the convex arm insert part away from the blocking part, so that the person can operate the annular rotating plate to rotate to the shell The other end of the part allows the main body of the operation part and the connection base to be disengaged to release the locking mechanism. In contrast, when attempting to return the ring-shaped rotating plate to the locked position, the operator must apply force or pull the convex arm in order to allow the embedded portion to fit into the blocking portion.

As those skilled in the art know, the structural features of the embodiment must operate a driver tool to push the convex arm, so that the position of the convex arm connected to the ring-shaped rotating plate is often and prone to stress concentration, or due to the force of personnel Inappropriate conditions may cause cracks or breaks at the position where the convex arm is connected to the annular rotating plate, and this situation is not what we expect.

Another issue related to the structural design and operation of the described embodiment is that in order for the annular rotating plate to be smoothly inserted into the groove seat of the connecting seat along the axial (longitudinal) direction of the combined hole, the connecting seat or the groove seat must be formed Open notch structure; said The open type notch structure often causes the ring-shaped rotating plate to shake or swing when a person operates a screwdriver tool to push the convex arm to release the above-mentioned locking operation. In other words, the combined structure of the conventional ring-shaped rotating plate and the connecting seat is not stable or ideal.

Representatively, these reference materials show the use and structural design of the operating unit body and connection base of the switchgear or their associated combination components. If the design and consideration of the assembly structure of the connection base, the rotating plate and related components are re-designed, and the above-mentioned application situation makes it different from the user, it will change its use pattern and increase its application range, which is different from the old one. law. For example, considering the effects of structure and ease of operation, the following topics must be included:

1. Improve the position of the convex arm connected to the circular rotating plate of the conventional structure and the situation where stress concentration is easy to occur, or the position of the convex arm connected to the circular rotating plate may be cracked or broken due to improper force.

2. The old method must be removed to allow the annular rotating plate to be inserted into the slot of the connection seat along the axial (longitudinal) direction of the combination hole. The structural characteristics and operation types of the connection seat: and to improve the conventional connection seat or slot seat, it must be open. Can solve or improve the conventional structure. When a person pushes the convex arm to release the locking operation, the ring rotating plate often causes shaking or swinging.

These topics have not been specifically taught or disclosed in the above reference materials.

That is, the main object of the present invention is to provide an improved structure of a switch assembly for a trigger combination, which provides a simple structure, a simple and stable combination operation, and the like. The switch device includes a combination of a connection base and a trigger body; the connection base has a combination hole and is pivotally connected to a (switch) body. The connection base is provided with a protection frame, and the protection frame and the walls on both sides of the connection base jointly define a lateral opening communicating with the combination hole for horizontally combining a trigger body. In essence, there are elastic deformation zones on both sides of the trigger body. When the mouth enters the connection seat, elastic deformation occurs, and the trigger body is allowed to reach the combined position, and the elastic deformation area is returned to the original state, so that the trigger body and the connection seat are firmly combined into an integrated form; the old method of rotating the plate is removed The structural characteristics and operation types of the connection seat inserted along the axial (longitudinal) direction of the combination hole have also improved the conventional notch structure in which the connection seat or the groove seat must be formed, often causing the rotating plate to shake or swing. Situation.
