Description

Switch wiring device

The present invention relates to a switch wiring 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 switch component having a connection circuit and 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 or turn off the power supply of the circuit by energizing or de-energizing the wire; 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 pivoting operation of the screw mechanism and the wire or the wire must use tools to operate the locking and relaxing work, which is relatively troublesome.

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, application of complex structures such as α-type metal shrapnel, etc.; or further enable the switch wiring device to allow personnel to directly operate the wires into the pivotal connection head without using tools, and to make the connection head conform to rigidity Or under the condition of high hardness, it has the means of good conductivity, auxiliary fixed metal shrapnel and guiding metal shrapnel movement path.

Head 40.

The figure shows two junctions 40 disposed within the housing chamber 11; each of the headers 40 includes a limiter 50 and two portions of the contacts 60 of the connection limiter 50. The restrictor 50 selects a material having a high rigidity or hardness (for example, iron, steel, etc.) to form a slab billet, and causes the restrictor 50 to form a rectangular frame structure shown in FIG. 1 from the form of the slab billet. And the combination of the contacts 60.

The figure also depicts that the limiter 50 has a first side 51, a second side 52 connecting the first side 51, a third side 53 connecting the second side 52, a fourth side 54 connecting the third side 53, and the like, and A rectangular frame structure having a space 55 is jointly formed to accommodate a metal dome 70. Also, at least the second side 52 and the fourth side 54 assist in standardizing the path of movement of the metal dome 70.

In the embodiment taken, the fourth side 54 is extended and bent toward the first side 51 to form a secondary side 56 (for example, the fourth side 54 and the secondary side 56 form an acute angle, a right angle or an obtuse angle) And, the secondary side 56 and the first side 51 are provided with connecting portions 56a, 51a, respectively, and can be joined to each other. It can be understood that the connection or fixing manner of the secondary side 56 and the first side 51 can also be applied to each other such as fitting, fastening, crimping, welding, and the like. And, the second side 52 and the fourth side 54 are provided with ribs 52a, 54a for increasing the structural strength of the restrictor 50.

The figure shows that the rib 52a of the second side 52 is inclined downward from the first side 51 toward the third side 53; the rib 54a of the fourth side 54 is from the secondary side 56 toward the third side 53. The shape in which the direction is inclined downward.

FIGS. 1 and 2 also depict the contact piece 60 having a first end 61 and a second end 62; the first end 61 is coupled to the first side 51 of the restrictor, and the second end 62 is in an inclined raised configuration toward the conductive element 30. The direction extends. The switch button 20 controls the conductive element 30 to selectively energize or de-energize the second end 62 of the contact. In detail, when the person presses the switch button 20, the conductive member 30 is driven to contact or leave the contact piece 60 or the contact second end 62, so that the power receiving head 40 is energized or de-energized.

The metal dome 70 is also shown to resemble a "V" shaped body having an opening, including a first segment 71, a second segment 72, and a curved segment 73 connecting the first segment 71 and the second segment 72. The first segment 71 has a combined end portion 74 of a tip end 74 and a hole type, which can be combined on the combined portion 53a of one of the convex portions of the third side 53 of the restrictor, so that the first segment 71 of the metal dome is positioned at the limiter. Within the space 55; and the head end 74 of the first section 71 of the metal dome and the upper end of the third side 53 of the restrictor are fixed together in a groove portion 13 of the housing chamber 11. And, the metal dome bending section 73 is wound around the column pile 14 of the housing chamber 11, so that the metal elastic piece second section 72 extends into the restrictor space 55 to form a swingable shape.

In the embodiment taken, the metal dome 70 is fitted behind the housing chamber 11 with its opening arranged in the direction of the conductive element 30 such that the arrangement angle of the second section 72 facilitates the insertion of the wire 90 into the combination; and the wire 90 is inserted The direction or angle is about the same as the angle of inclination of the first end 61 of the contact, such that the wire 90 and the first end 61 of the contact piece form a larger contact area than the conventional structure, and closer to the conductive element 30, which also increases the electrical conductivity and Combination stability. It is obviously different from the conventional art application type of α-type metal shrapnel or screw mechanism locking wire.

2 shows in particular that after the person directly operates the wire 90 into the wire insertion hole 12, the tail end 76 of the second segment 72 of the metal dome presses the wire 90 against the first end 61 of the contactor to form a conductive state. At this time, the conductive member 30 is in a position in contact with the second end 62 of the contact piece to form an energized state. 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.

Figures 1 and 2 also depict the structural form in which the metal dome 70 is received within the restrictor 50, at least such that the second side 52 and the fourth side 54 of the restrictor collectively regulate the path of movement of the second section 72 of the metal dome without It will be yawed to the sides, which helps to increase the movement of the metal dome 70 and to operate the metal spring 70 to combine the stability of the wire 90.

In particular, when the operation wire 90 is inserted into the space 55 of the housing chamber 11 and the restrictor 50, the wire 90 is confined in the high-hardness limiter space 55, so that the bare metal end of the conventional art wire is not inserted or In the case of scraping the casing, or in the case of an operating environment, an occasion (for example, a vibration of the machine equipment, etc.) or an inadvertent collision, the wire is swung over the inside of the casing by an excessively large angle, twisted, or the like, and the casing is opened.

The imaginary line portion of Fig. 2 shows the personnel operable tool 80 extending from the lower end of the housing 10 into an operating opening 15 into the chamber 11 and the restrictor space 55, pushing the second section 72 of the metal dome so that the second end 76 Leaving the wire 90, the second portion 72 of the metal dome is released from the state of the wire 90, so that the person can directly remove the wire 90 and leave the housing 10.

In a possible embodiment, depending on 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 or the chamber 11 in a reliable manner. The shoulder 16 makes the combination of the limiter 50 and the housing 10 more stable.

Referring to FIG. 3, the limiter 50 and the contact piece 60 form an integrally formed structure. That is, the first end 61 of the contact and the first side 51 of the limiter form an integrally connected configuration.

Referring to Figures 4 and 5, a modified embodiment of the power head 40 is disclosed. Depending on the combination of the housing 10 (or the chamber 11) and the switch button 20, the second end 62 of the contact head 40 faces the direction of the restrictor space 55 (or the lower side of the figure or the opening direction of the metal dome 70). Bending, extending to form a secondary end 63 (eg, forming the second end 62 and the secondary end 63 at an acute angle, a right angle or an obtuse angle); and bending from the secondary end 63 toward the conductive element 30 or the switch button 20 Extending to form a trailing end 64 (eg, forming the secondary end 63 and the trailing end 64 at an acute angle, a right angle or an obtuse angle).

Fig. 5 shows that when a person operates the switch button 20 to drive the conductive member 30 to the lower side in the drawing, the conductive member 30 contacts the tail end 64 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 device has the following advantages compared with the old method under the condition of not increasing the housing volume and conforming to the trend of miniaturization of the switch terminal device: 1. The shell The structure of the body 10, the switch button 20, the conductive element 30 and the limiter 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 secondary side 56, together to create a frame structure having a space 55 to accommodate the metal dome 70; The metal dome 70 has a first section 71 that fits or connects the first side 51 of the restrictor, and the curved section 73 wraps around the stud 14 of the housing 10 such that the second section 72 is gauged to move within the restrictor space 55 and allows personnel The direct operation wire 90 is inserted into the chamber 11 and is pressed against the limiter 50 by the second metal piece 72. The contact piece 60 is formed with the first end 61 and the second end 62. The second end 62 and the conductive member 30 form a contact. The part that is not touched or the like is obviously different from the conventional one, and it also changes its use and operation type, which is different from the old method. 2. In particular, the old method must be used for the disassembly and assembly of the wiring circuit or the wire. It is necessary to operate the screw to lock and loosen the trouble. When the screw is in the released state, the screw will be skewed, causing the human operating screw to align the locking wire and The operation of the power receiving head becomes troublesome and difficult, or the application of the α-type metal dome, the guiding groove and the guide bar and the spring-fitted structure on the insulating housing and the power receiving head make the structure more complicated and increase the manufacturing cost. And the volume of the casing, or the vibration of the machine equipment, causing the screws to loosen, causing the wire to loosen, etc., have been significantly improved. 3. The power receiving head 40 has the functions of good electrical conductivity, auxiliary fixed metal elastic piece 70 and guiding metal elastic piece 70 under the condition of high rigidity or high hardness. Moreover, the limiter 50 corresponds to the structure for accommodating the metal dome 70 and the wire 90, and not only provides the user's simple operation, but also improves the old-fashioned wire metal bare end to insert the casing or the metal dome to yaw and scrape the shell. Body, clamping instability, etc.

Therefore, the present invention provides an effective switch wiring device, the spatial type of which is different from the conventional one, and has the advantages unmatched in the old method, and shows a considerable progress, and has fully complied with the invention patent. The essentials.
