Description

Switch wiring improvement device

The present invention relates to a switch wiring improvement device; in particular, a switch wiring device is provided with a limiter, a contact piece, a combined metal dome to facilitate direct pivoting of the wire; and, in the case of a higher rigidity, the limiter is Auxiliary to fix and standardize the movement path of metal shrapnel.

The switch wiring device is a power switching element having a connection circuit or a line, and is installed in an operation panel or a distribution box of an electronic or electrical device to connect the wiring circuit. The switch wiring device is applied to a conductive component, a screw-locked electronic device, a wiring circuit or a wire of a motor device, which is covered in an insulating case (usually made of a plastic material), and controls the conductive component and the wiring circuit with the operation of the switch button or It is a well-known technique to establish the power supply of the open and close circuits by energizing or de-energizing the wires; for example, Taiwan Patent No. 103206602 "Switching Terminal Block Structure" patent provides a typical embodiment.

One problem related to the operation and structural design of such a switch wiring device is that the insulating housing is provided with a connecting wire hole and a locking hole for the operating screw, and a person operating tool is provided to control the screw locking from the wire insertion hole. wire. In practice, the screw must be in the released state so that the wire can be inserted into the plug hole; when the screw is in the released state, the screw will be skewed, so often the person operates the screw to align the lock wire and connect The operation of the electric head (or electric terminal) becomes troublesome and difficult.

In order to improve the above problems, the old method also discloses a structure in which a guide groove and a guide bar and a spring are provided on an insulating case and a power receiving head. However, the structure is not only complicated, but also increases the manufacturing cost; and, it is usually necessary to increase the volume of the casing to avoid interference between the guiding structure and the conductive member. Furthermore, increasing the volume of the housing is also detrimental to the evolution and design trend of miniaturization of the switch terminal device.

In some environments (such as the vibration of the machine equipment), the long-term use process, it is easy to loosen the screw, causing the wire to loosen. In particular, the screwing mechanism of the screw mechanism and the wire or wire must use tools to operate the locking and relaxing work, which is relatively cumbersome; this situation is not what we expected.

The old method also reveals a structure that fits the internal structure of the casing, and uses a metal dome that is shaped like an α-profile to press a wire or a wire to replace the structure of the screw-locking wire. However, as those familiar with the art know, in addition to bending into a special shape, the α-shaped metal dome must also have a mouth on the metal dome so that the other end of it passes through the mouth, at the mouth. A swingable structure is formed thereon to press the wire. Therefore, the α-type metal shrapnel is cumbersome and complicated in structure fabrication; this situation is not what we would expect.

Representatively, these references show the skill in the design of the switch wiring device and related combinations; if the re-design considers the structural combination of the insulating housing and the conductive components, the connector, and the switch, the structure is different. The learner will be able to change its use form, which is different from the old one; in essence, it will also increase its application range. For example, under the condition that the volume of the switch wiring device is not increased, the structure thereof is easy to manufacture and operate, and the operation and the difficulty of the conventional operation screw for aligning the locking wire and the power receiving head are improved, and the insulating housing combination guiding groove is improved. , guide bars, springs, the application of complex structures such as α-type metal shrapnel, etc.

And, it is considered to provide a terminal device provided with a limiter; the limiter has a first space and a second space, and at least two parallel wires can be inserted into the casing to respectively combine the mechanisms of the metal dome. Or further enabling the switch wiring device to allow a person to directly operate the wire into the pivotal connection head without using a tool, and to have the conductive head and the auxiliary fixed metal dome under the condition of high rigidity or high hardness.

If the person presses the switch button 20 to drive the conductive member 30 to move downward in the figure to cause the conductive member 30 to leave the second end 62 of the contact, a power-off state is formed.

Referring to Figures 3 and 4, the structural form in which the metal dome 70 is received in the restrictor 50 is depicted, at least the second side 52 of the limiter and the first secondary side 56 collectively regulate the movement of the first leg 78 of the metal dome. The path is not yawed to the sides; the fourth side 54 and the second side 57 jointly define the path of movement of the second leg portion 79 of the metal dome without yawing to the sides; this helps to increase The movement of the metal dome 70 and the operation of the metal dome 70 combine the stability of the wires 90 and/or 95.

In particular, when the operating wires 90 and/or 95 are inserted into the first space 58 and/or the second space 59 of the housing chamber 11 and the restrictor 50, the wires 90 and/or 95 are limited to the first limit of the high hardness limiter. In the space 58 and/or the second space 59, there is no case where the bare metal end of the conventional technical wire is inserted or scraped, or because of the operating environment, occasions (for example, vibration of the machine equipment, etc.) or Inadvertent collision, causing the wire to swing excessively inside the casing, twisting, etc., and expanding the casing.

Figures 3 and 4 also show that the human operable tool 80 extends from the lower end of the housing 10 into the chamber 11 and the restrictor first space 58 or the second space 59, pushing the metal spring first foot 78 or The second leg portion 79 causes the tail end of the first leg portion 78 or the tail end of the second leg portion 79 to leave the wire 90 or 95, and the second portion 72 of the metal spring piece is released from the state of the wire 90 or 95, so that the person can directly remove the wire. 90 or 95 leaves the housing 10.

Referring to FIG. 6, in a possible embodiment, according to the shape of the housing chamber 11, the second side 52 and the fourth side 54 of the restrictor 50 are formed with recesses 52b, 54b formed in the housing 10 in a reliable manner. Or the shoulder 16 on the chamber 11 makes the combination of the restrictor 50 and the housing 10 more stable.

Referring to Figures 7 and 8, a modified embodiment of the power head 40 is disclosed. According to the combination of the housing 10 (or the chamber 11) and the switch button 20, the second end 62 of the contact of the power head 40 faces the limiter 50 (or the first space 58, the second space 59 or the lower part of the figure Or the direction of the opening of the metal dome 70 is bent to form a secondary end 63 (for example, the second end 62 and the secondary end 63 form an acute angle, a right angle or an obtuse angle); and from the secondary end 63 toward the conductive element 30 Or the direction of the switch button 20 is bent to extend to form a trailing end 64 (e.g., such that the secondary end 63 and the trailing end 64 form an acute angle, a right angle or an obtuse angle).

Figure 8 shows that when a person operates the switch button 20 to drive the conductive member 30 to the lower side of the figure, the conductive member 30 touches the tail end 64 of the sheet to form an energized state. If a person operates the switch button 20 to move the conductive member 30 upwardly in the figure, the conductive member 30 will leave the contact tail 64 to form a power-off state.

Typically, the switch wiring improvement device has the following advantages compared with the old method under the condition that it does not increase the volume of the casing and conforms to the trend of miniaturization of the switch terminal device: 1. The related component structures of the housing 10, the switch button 20, the conductive member 30 and the restrictor 50, the contact piece 60, the metal dome 70, and the like have been redesigned. For example, the limiter 50 includes a first side 51, a second side 52, a third side 53, a fourth side 54 and/or a fifth side 55; the first side 51 is bent to form a first secondary side 56, a fifth side 55 is bent to form a second secondary side 57, and a frame structure having a first space 58 and a second space 59 is jointly formed to receive the first leg portion 78 and the second leg portion 79 of the metal dome 70; the metal dome 70 has The first segment 71 is fitted or connected to the third side 53 of the restrictor, and the curved portion 73 is wound around the stud 14 of the housing 10 such that the first leg portion 78 and the second leg portion 79 of the second segment 72 are standardized in the limiter.
