Description

Switch wiring device

Technical Field

The present invention relates to a switch wiring device; in particular to an invention that a switch wiring device is provided with a limiter, a contact piece and a combined metal elastic piece to be beneficial to directly pin-jointing a conducting wire and ensure that the limiter assists in fixing and standardizes the motion path of the metal elastic piece under the condition of higher rigidity.

Background

The switch wiring device is a power switch assembly with a connecting circuit and a line, is arranged on an operation panel or a distribution box of electronic and motor equipment and is used for connecting a wiring circuit. The switch wiring device uses a conductive component covered in an insulating shell (usually made of plastic material), a wiring circuit or a lead of electronic and motor equipment locked by a screw, and controls the power-on or power-off of the conductive component and the wiring circuit or the lead by matching with the operation of a switch button, thereby establishing the function of switching on and off a circuit power supply, which is the prior art; for example, taiwan patent No. 103206602 discloses a switch terminal block structure, which provides an exemplary embodiment.

One problem with such switch wiring devices in terms of operational use and structural design is that the insulating housing is provided with a wire insertion hole and a locking hole for the operating screw which are in communication with each other, and personnel operating tools are provided to control the screw to lock the wire entering from the wire insertion hole. In practice, the screw must be in a release state to allow the wire to be inserted into the wire insertion hole; when the screw is in the released state, the screw may be deflected, which often makes the operation of the screw to align the locking wire and the electrical contact (or electrical contact) troublesome and difficult.

In order to improve the above problems, the old method also discloses a structure of arranging a guide slot, a guide bar and a spring on the insulating shell and the contact. But the structure is not only more complex, increasing the manufacturing cost; also, the housing volume must generally be increased to avoid interference between the guide structure and the conductive components. Furthermore, increasing the volume of the housing is not conducive to the evolution and design trend of miniaturization of the switch terminal block device.

In some use environments (for example, the operation of machine equipment can generate vibration), the screw is easy to loosen in the process of long-term use, so that the wire is easy to loosen. In particular, the screwing mechanism and the wire or wire rod are pivoted only by using tools to operate the locking and loosening work, which is relatively troublesome.

However, as known to those skilled in the art, besides bending the α type metal spring plate into a special shape, a mouth must be formed on the metal spring plate, so that the other end of the metal spring plate passes through the mouth to form a swinging structure on the mouth so as to press the lead, therefore, the α type metal spring plate is troublesome and complicated in structure manufacturing, which is not desirable.

Typically, these references show the skill in the art of designing the switch wiring device and related assemblies, and if the design is redesigned to take into account the structural combination of the insulating housing and conductive elements, contacts, and switches, making the structure different from the conventional one, it will change the usage form and be different from the old one, and substantially increase the application range.

Detailed Description

Referring to fig. 1 and 2, the switch wiring device of the present invention includes a combination of an insulating housing and a switch button, which are respectively designated as 10 and 20. The housing 10 has a cavity 11 for accommodating the switch button 20; the switch button 20 incorporates a conductive element 30 and a spring 35 (this part is a published art and therefore will not be described in detail). According to the orientation of fig. 1 and 2, the housing 10 is provided with wire insertion holes 12 communicating with the cavity 11 at the lower end regions of both sides, and a wiring circuit or a lead 90 for electronic or motor equipment is inserted into the housing cavity 11 to be combined and connected with the electric connector 40.

Two electrical contacts 40 are shown disposed within the housing chamber 11; each contact 40 includes two parts, a limiter 50 and a contact 60 connected to the limiter 50. The limiter 50 is formed from a flat sheet of material selected for its rigidity or hardness (e.g., iron, steel, etc.) and the limiter 50 is formed from the flat sheet of material into the rectangular frame structure and contact 60 combination shown in fig. 1.

The figure also shows that the limiter 50 has a first side 51, a second side 52 connected to the first side 51, a third side 53 connected to the second side 52, a fourth side 54 connected to the third side 53, etc., which together establish a rectangular frame structure with a space 55 for accommodating a metal spring 70. And, at least the second side 52 and the fourth side 54 are made to assist in regulating the moving path of the metal dome 70.

In the illustrated embodiment, the fourth side 54 is bent and extended in the direction of the first side 51 to form a secondary side 56 (e.g., such that the fourth side 54 and the secondary side 56 form an acute, right or obtuse included angle); the sub-side 56 and the first side 51 are provided with connecting

portions

56a and 51a, respectively, and can be joined to each other. It is understood that the secondary side 56 and the first side 51 may be connected or fixed by engaging, snapping, riveting, welding, etc. And, the second and

fourth sides

52, 54 are provided with

ribs

52a, 54a to increase the structural strength of the limiter 50.

The rib 52a of the second side 52 is shown in a downward inclined configuration from the first side 51 toward the third side 53; the rib 54a of the fourth side 54 is inclined downward from the secondary side 56 toward the third side 53.

Fig. 1 and 2 also depict wafer 60 having a first end 61 and a second end 62; the first end 61 is connected to the limiter first side 51, and the second end 62 is in an inclined and tilted structure and extends toward the contact conductive element 30. The switch button 20 controls the conductive member 30 to selectively energize or de-energize the contact second end 62. In particular, when a person presses the switch button 20, the conductive element 30 is moved into and out of contact 60 or contact second end 62, thereby energizing or de-energizing the power contact 40.

The figure also shows that the metal dome 70 is shaped like a V-shaped body with an opening, and comprises a first section 71, a second section 72 and a curved section 73 connecting the first section 71 and the second section 72. The first section 71 has a head 74 and a hole-type combination portion 75, which can be combined with a protrusion-type combination portion 53a of the third side 53 of the limiter, so that the metal dome first section 71 is located in the limiter space 55; the head end 74 of the first metal spring piece section 71 and the upper end of the third side 53 of the stopper are fixed together in one groove 13 of the housing chamber 11. And the bent section 73 of the metal elastic sheet is wound on a pillar 14 of the housing cavity 11, so that the second section 72 of the metal elastic sheet extends into the limiter space 55 to form a swinging state.

In the illustrated embodiment, the metal dome 70 is mounted in the housing cavity 11 with its opening oriented toward the conductive element 30 such that the second section 72 is disposed at an angle that facilitates insertion of the conductive wire 90 into the conductive element, and the insertion direction or angle of the conductive wire 90 is approximately the same as the inclination angle of the first contact end 61, such that the conductive wire 90 and the first contact end 61 form a larger contact area than the conventional structure, and are closer to the conductive element 30, thereby increasing the conductive efficiency and the assembly stability.

Fig. 2 particularly shows that after a person directly inserts a wire 90 into wire insertion hole 12, tail end 76 of second section 72 of the metal dome presses wire 90 against first end 61 of the contact to form a conductive state. At this point, the conductive element 30 is in contact with the contact second end 62, creating a conductive state. If a person presses the switch button 20, the conductive element 30 is displaced downward in the figure, and the conductive element 30 is moved away from the contact second end 62, thereby forming a power-off state.

Fig. 1 and 2 also illustrate the configuration of the metal dome 70 received in the limiter 50, such that at least the second side 52 and the fourth side 54 of the limiter jointly regulate the moving path of the second section 72 of the metal dome without deflecting to two sides, which helps to increase the movement of the metal dome 70 and the stability of the operation of the combined conducting wire 90 of the metal dome 70.

In particular, when the wire 90 is inserted into the housing cavity 11 and the space 55 of the stopper 50, the wire 90 is limited in the stopper space 55 with high hardness, so that there is no situation that the bare metal end of the wire in the prior art damages or scrapes the housing, or the wire swings at an excessive angle, twists, etc. in the housing due to the operating environment, occasion (e.g., operation vibration of machinery, etc.) or careless collision, and thus the housing is opened.

The phantom line of fig. 2 shows that the human operable tool 80 extends into the chamber 11 and the restraint space 55 from an operation hole 15 at the lower end of the housing 10, pushes the second section 72 of the metal dome to separate the tail end 76 of the second section from the wire 90, and releases the state that the second section 72 of the metal dome presses the wire 90, so that the human can directly remove the wire 90 from the housing 10.

In one possible embodiment, the second and

fourth sides

52, 54 of the limiter 50 are formed with

recesses

52b, 54b that, depending on the shape of the housing chamber 11, may engage a shoulder 16 formed on the housing 10 or chamber 11 to make the combination of the limiter 50 and the housing 10 more stable.

Referring to fig. 3, the limiter 50 and the contact 60 are formed as an integral structure. That is, the first contact end 61 and the first limiter edge 51 are integrally connected.

Referring to FIGS. 4 and 5, a modified embodiment of the electrical connector 40 is disclosed. Depending on the combination of the housing 10 (or the chamber 11) and the switch button 20, the contact second end 62 of the contact 40 is bent toward the limiter space 55 (or downward in the drawing or toward the opening of the metal spring 70) to extend to form a secondary end 63 (e.g., such that the second end 62 and the secondary end 63 form an acute, right or obtuse included angle); and bent from the secondary end 63 toward the conductive member 30 or the switch button 20 to form a tail end 64 (e.g., such that the secondary end 63 and the tail end 64 form an acute angle, a right angle or an obtuse angle).

Fig. 5 shows that when the switch button 20 is operated by a person to move the conductive element 30 downward in the figure, the conductive element 30 contacts the tail end 64 of the contact, and thus the conductive element is in a power-on state. If a person operates the switch button 20 to displace the conductive element 30 upward in the figure, the conductive element 30 will move away from the contact tail end 64, resulting in a power-off state.

Typically, the switch terminal device has the following advantages compared with the old method under the condition that the volume of the housing is not increased and the miniaturization design trend of the switch terminal device is met:

1. the structure of the housing 10, the switch knob 20, the conductive member 30 and the related components such as the limiter 50, the contact 60, the metal dome 70, etc. 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, which together form a frame structure having a space 55 for accommodating the metal elastic sheet 70; the metal elastic sheet 70 has a first section 71 embedded or connected with the first side 51 of the limiter, a bent section 73 is wound around the stud 14 of the shell 10, so that the second section 72 is regulated to move in the limiter space 55, and a person is allowed to directly operate the lead 90 to be inserted into the cavity 11 and pressed on the limiter 50 by the metal elastic sheet second section 72; the contact 60 is formed with a first end 61, a second end 62, and the second end 62 and the conductive element 30 are formed in a contact or non-contact manner, which is different from the conventional one, and the usage and operation of the contact are also changed, which is different from the conventional one.

2. Especially, the old method must operate the troublesome work of locking and loosening the screw for the disassembling and assembling of the wiring circuit or the lead, when the screw is in the loosening state, the screw will be deflected to cause the operation of aligning the screw with the locking lead and the electric connector, which becomes troublesome and difficult, or the situation that the structure becomes more complicated, the manufacturing cost and the volume of the shell are increased, or the operation vibration of the machine equipment causes the screw to loosen, the wire to loosen and the like is obviously improved by applying the α type metal elastic sheet and arranging the guide groove, the guide bar and the spring on the insulating shell and the electric connector.

3. The electric contact 40 has the functions of good conductivity, assisting in fixing the metal elastic sheet 70, guiding the movement path of the metal elastic sheet 70 and the like under the condition of high rigidity or hardness. Moreover, the limiter 50 is adapted to accommodate the metal spring 70 and the lead 90, which not only provides a simple operation for personnel, but also improves the situations of the prior art, such as inserting the bare metal end of the lead into the housing, causing the metal spring to deflect, scratching the housing, and causing unstable clamping.

Therefore, the present invention provides an effective switch wiring device, which has a spatial pattern different from the known one and has incomparable advantages in the old law, and represents a great progress, and fully meets the requirements of the invention patent.
