Description

Improved structure of wiring assembly for terminal device

Technical Field

The invention relates to a wiring assembly structure for a terminal device; in particular to a technology for establishing a plurality of pressing fixed wires by matching a metal spring plate of a wiring assembly with a movable handle to generate motion.

Background

It is known in the art to use metal components (or conductive components) and spring conductors (or metal spring) encased in an insulating housing (typically made of plastic material) to press or bond wires into terminals to form terminal devices or wire terminals that electrically couple or release the wires. For example, CN 102204015A "electrical connection terminal "、DE 29915515U1、EP2325947A1、US 2013/0143433A1"CONNECTION TERMINAL"、US 2014/0127932A1"ELECTRICAL CONNECTION TERMINAL"、DE 10 2012 009 286A1、US 5362259" to ground conductive terminal (GROUND CONDUCTOR TERMINAL)" patent, etc., provides a typical embodiment.

Such electrical coupling terminal devices typically include an insulating housing; the shell is provided with a wire inlet hole, so that the wire can be inserted into the shell. The housing also defines a cavity for fitting the conductive bracket (or conductive element) and the metal spring, so that the metal spring and the conductive element press the wires inserted into the housing to form contact or electrical connection. Unless a person operates other tools to extend into the housing to push the metal spring, the electrical connection or contact state between the wire and the metal spring and between the wire and the conductive assembly can be released.

One problem associated with the prior art terminal device assembly structure in terms of structure and operation application is that in the use situation of some terminal devices pin-jointed wires (or wires with large wire diameters), after the wires are inserted, sufficient fixing force is not obtained to generate deflection and shaking of the metal tail ends of the wires, or the wires are not firmly pressed by metal spring plates and conductive components, or the wires are rotated and deflected due to accidental touching by personnel, so that the poor contact safety problem is caused.

In order to improve the pressing force and the electrical safety or efficiency, the prior art has disclosed a means for locking the wires by using screws, or a double-layer metal spring or a structure for increasing the thickness of the metal spring and the electrical conductive element, so as to improve the pressing force. The old method also discloses a technology for combining the follower with the pressing arm by using two metal spring plates; such as ,DE202017107202U1、DE 202017107208U1、US 2018/0006385A1"ELECTRICAL CONNECTIONTERMINAL WITH A TWO-PART OPERATING ELEMENT", provides a viable embodiment. In the embodiment, one ends of the two metal elastic sheets are overlapped and fixed on the follow-up body, and the follow-up body is pressed by a pressing arm operated by a person, so that the follow-up body drives the other ends of the two metal elastic sheets to form two pressing points for pressing the inserted lead wires, and an electric connection state is formed.

As known to those skilled in the art, the operation of locking or releasing the wire by using the screw or the structure of combining the follower and the pressing arm by stacking one end of the two metal spring plates together is complicated, and the assembly or processing operation is troublesome and time-consuming, thus relatively increasing the production cost. Or the number or thickness of the metal spring plates and the conductive components is increased, so that the manufacturing cost is high, and the operation is laborious; while these situations are not it is desirable to have a device.

Typically, these reference data show the art regarding the design and application of the terminal device in terms of structural assembly; if the structural combination of the wiring component and the metal spring plate is considered in the re-design, the structure is different from the prior art, the use form of the wiring component and the metal spring plate can be changed, and the wiring component and the metal spring plate are different from the old method; in essence, it also increases its range of application.

We have found that a more desirable structural configuration of the terminal device or wiring assembly must overcome or ameliorate the above-discussed problems; the following design considerations should also be included, including:

1. Under the condition that the thickness of the metal elastic sheet is not increased, the wiring assembly is provided with a plurality of pressing mechanisms, so that the matching structure of the wiring assembly can provide enough pressing force and can be applied to occasions where certain electric connection terminals are pivoted with large-diameter wires, the structure and the function of fixing the wires are obtained, and the situations that the force of pressing the wires by the structure in the prior art is insufficient, the pressing is unstable, the wires are easy to deviate and shake (or the wires are touched by personnel carelessly), poor contact safety is caused and the like are improved.

2. The structure of the screw locking lead or the combined follower and the pressing arm which are overlapped at one end of the two metal spring plates is removed by the old method, so that the situations that the structure of the prior art is complex, the assembly/processing operation and the operation are troublesome, time-consuming and labor-consuming, the production cost is relatively increased, and the like are improved, and the effects of improving the manufacturing, processing and assembling efficiency are achieved; and, provide more or bigger contact area and contact force, relatively raise the conductive efficiency and suitable for the structural style of effects such as the big, small-diameter wire, etc..

These problems are not taught or specifically disclosed in the above references.

Detailed Description

The following description of the present invention will be made clearly and fully, and it is apparent that the embodiments described are some, but not all, of the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1,2 and 3, the improved structure of the wiring assembly for the terminal device of the present invention comprises a combination of a conductive frame and a metal spring plate, generally indicated by reference numerals 20 and 30, respectively. The wiring member is fitted with a movable handle 10 and the like, and is installed in a chamber 99 of a housing 90 made of an insulating material to constitute a terminal device. Basically, the housing 90 is provided with an entry hole 95 for the insertion of the wire 50.

In the following description, it is assumed that references to upper, lower, sides, etc. are made to the directions shown in the drawings as reference directions.

In the embodiment adopted, the conductive frame 20 is made of a conductive material into a plate-like body structure and is disposed inside the housing chamber 99; the conductive frame 20 has an end portion 21, and the end portion 21 may form a concave arc structure 22 (and/or a tooth portion 23 formed on the concave arc structure 22) for assisting in guiding and positioning the conductive wire 50.

The metal spring 30 is shown disposed and assembled on the stud 93 of the housing cavity 99 to form a reciprocable pattern. The metal spring plate 30 is provided with a first section 31, a second section 32 and a base section 33 connecting the first section 31 and the second section 32; and, a first curved portion 34 is formed between the first section 31 and the base section 33, and a second curved portion 35 is formed between the second section 32 and the base section 33.

In a possible embodiment, the first section 31 of the metal elastic sheet 30 is provided with a first bending portion 36, and the tail end 37 of the first section 31 extends obliquely towards the second section 32; the second curved portion 35 of the metal elastic sheet 30 combines the protruding piles 93 (or winds around the protruding piles 93), and the second section 32 (or near the tail end 39 of the second section 32) is provided with the second bending portion 38, so that the tail end 39 of the second section 32 extends towards the same direction as the tail end 37 of the first section, and a plurality of pressing mechanisms are formed together.

FIGS. 1,2 and 3 also depict the construction of the actuator handle 10; the actuating lever 10 includes a pivot portion 11, an operating portion 12 connecting the pivot portion 11, and a pressing portion 13. The pivot 11 is assembled to the post 91 of the housing 90 (or the chamber 99) to form the reciprocating motion of the actuating lever 10. The operating portion 12 has a mouth 14 for insertion of a tool (e.g., a screwdriver or the like) to operate the movement of the actuating lever 10. And teeth 15 are formed on the periphery or at least partial area of the periphery of the mouth 14 for the hand of a person to operate the actuating handle 10.

In the adopted embodiment, the pressing part 13 cooperates with a personnel to operate the actuating handle 10, so as to press the base section 33 of the metal spring plate 30 or release the pressing state, control the whole metal spring plate 30 to generate (rotating) motion, and form a plurality of pressing mechanisms or pressing areas for the wires 50 entering the wiring assembly; the wire of the prior art is easy to deviate or shake due to external force, and the contact is unstable, so that the conduction efficiency, the safety and the like are affected.

The housing 90 (or chamber 99) is also shown with a boss 94, which combines the structure of the spring 40. The elastic means 40 comprises a base 43 combined on a boss 94, and a first arm 41 and a second arm 42 (contacting the metal elastic sheet 30 or the base section 33) protruding from both ends of the base 43. The end of the first arm 41 is bent and extended towards the second arm 42 to form an extension section 44, so that the first arm 41 (or the extension section 44) can form a supporting function by the housing 90 when the elastic device 40 responds to the movement of the actuating handle 10; and, the end of the second arm 42 is bent and extended towards the first arm 41 to form a pair of sections 45, which can facilitate the movement of the second arm 42 to push the metal elastic sheet 30.

In a possible embodiment, the secondary segment 45 forms a U-shaped or L-shaped structure to assist in increasing the stability of the movement of the second arm 42 (or the secondary segment 45) pushing against the metal dome 30 (or the base segment 33).

In the preferred embodiment, the wiring assembly incorporates a frame 60 of metallic material that is commonly housed within a housing 90 or chamber 99. The frame 60 has a pivot hole 61 provided in an upper region through which a post 91 of the housing 90 passes, combines the pivot portions 11 of the levers 10, and allows the levers 10 (or at least the lever pressing portions 13) to move within the frame 60. And the frame 60 is provided with a combination hole 63 for the protruding pile 93 to pass through the second curved arc portion 35 of the combined metal elastic sheet 30, and allows the metal elastic sheet 30 to move in the frame 60.

The frame 60 is also shown to include a bottom 66 and an opening 65; the opening 65 allows the conductive frame 20 (or the end portion 21) to extend into the frame 60, so that at least the conductive frame 20 (or the end portion 21) and the bottom 66 of the frame form a contact. The frame 60 defines a gap 62 above the opening 65 and a shoulder 64 above the gap 62; the notch 62 allows the first arm 41 and the second arm 42 of the spring 40 to extend into the frame 60, while allowing the second arm 42 to contact the lower portion of the base section 33 of the metal spring 30. And, when the spring 40 responds to movement of the actuator stem 10, the first arm 41 may bear against the shoulder 64 (unlike the application housing 90 described above) to establish the support described above, providing for the spring 40 to accumulate or release energy.

It can be appreciated that the combined structure of the frame 60, the handle 10, and the metal spring 30 helps to strengthen the combined structure and stability during high frequency or long term use operation.

Referring to fig. 3, the left area of the figure shows the metal spring 30 in a released state, so that a person can operate the insertion operation of the wire 50. When a person operates the actuating handle 10 to press the base section 33 of the metal spring plate 30 by the pressing part 13, the tail ends 39 of the two second sections 32 are pressed to fix the wire 50, so as to establish a first pressing area; and, the elastic device 40 is caused to accumulate energy.

When the person continuously operates the pressing part 13 of the actuating handle 10 to press the metal elastic sheet 30 (and the elastic device 40 continuously stores energy), the tail end 37 of the first section 31 clamps the wire 50 to form a fixed state, and a second pressing area is established; for example, the right region of fig. 3 shows a case where the metal dome 30 establishes a plurality of pressing mechanisms.

Therefore, when the operator operates the actuating handle 10 to rotate back or return, the second arm 42 of the elastic device 40 pushes the metal spring plate 30 upwards in the drawing to allow the operator to withdraw or insert the wire 50 in cooperation with the elastic device 40 to release energy; for example, the left region of fig. 3 depicts the situation.

It should be noted that, when the operator operates the actuating handle 10 to move, the metal spring plates 30 are configured such that they can generate a plurality of pressing areas for the wire 50 in a segmented (or gradual) manner, so as to achieve the effect of saving operation. And, the first section 31 cooperates with the structure of the first bending part 36, so as to improve the pulling resistance of the tail end 37 of the first section for pressing the wire 50; in addition, the combination of the shape of the tail end 39 of the second section 32 (or the second bending portion 38) pressing the end region of the wire 50 can significantly improve the fixing effect of the wire 50 (especially the wire with large wire diameter), and the contact area (or contact area) and contact force of the wire 50 and the conductive frame 20, thereby relatively increasing the conductive efficiency.

Referring to fig. 4, a derivative embodiment of the metal spring 30 is shown. The first section 31 of the metal elastic sheet 30 is inclined from the first curved portion 34 toward the second section 32 to form a straight line extending shape. Compared to the above embodiment (the first segment 31 is formed with the first bending portion 36), the tail end 37 of the first segment 31 is located closer to the tail end 39 of the second segment 32, so that the tail end 37 of the first segment 31 can directly press the wire 50.

Referring to fig. 5 and 6, the structure of the wiring assembly using a plurality of metal spring plates 30 (the plurality includes a plurality of metal spring plates 30; e.g., more than 3 metal spring plates 30) is shown. The bimetal spring plate 30 (or three metal spring plates 30) is arranged and combined on the protruding pile 93 of the housing cavity 99 to form a reciprocating movement type. The two metal spring plates 30 (or three metal spring plates 30) are respectively provided with a first section 31, a second section 32 and a base section 33 for connecting the first section 31 and the second section 32; at least a partial region of the base sections 33 of the two metal spring plates 30 (or three metal spring plates 30) is formed in a stacked manner. And, a first curved portion 34 is formed between the first section 31 and the base section 33, and a second curved portion 35 is formed between the second section 32 and the base section 33.

In a possible embodiment, the first sections 31 of the bimetal elastic sheet 30 (or the three metal elastic sheets 30) are respectively provided with a first bending portion 36, at least two first sections 31 (or the three first sections 31) are formed in a separated state, and the tail ends 37 of the first sections 31 are inclined and extended towards the direction of the second sections 32; the second curved portions 35 of the bimetal elastic sheet 30 (or the three metal elastic sheets 30) combine the protruding piles 93 (or are wound on the protruding piles 93), and the two second sections 32 (or the tail ends 39 close to the second sections 32 and/or the three second sections 32) are respectively provided with the second curved portions 38, so that the tail ends 39 of the two second sections 32 (or the three second sections 32) extend towards the same direction as the tail ends 37 of the first sections, and at least the tail ends 39 of the two second sections 32 (or the three second sections 32) form a separated type, so as to jointly form a plurality of pressing mechanisms.

The left region of fig. 6 shows the metal spring 30 in a released state, so that a person can operate the insertion operation of the wire 50. When a person operates the actuating handle 10 to press the base section 33 of the metal spring plate 30 by the pressing part 13, the tail ends 39 of the two second sections 32 are pressed to fix the wires 50, so as to establish a first pressing area and a second pressing area; and, the elastic device 40 is caused to accumulate energy.

When the person continuously operates the pressing part 13 of the actuating handle 10 to press the metal elastic sheet 30 (and the elastic device 40 continuously stores energy), the tail ends 37 of the two first sections 31 clamp the wire 50 to form fixation, and a third pressing area and a fourth pressing area are established; for example, the bimetallic spring 30 shown in the right region of fig. 6 establishes multiple pressing mechanisms.

Therefore, when the operator operates the actuating handle 10 to rotate back or return, the second arm 42 of the elastic device 40 pushes the metal spring plate 30 upwards in the drawing to allow the operator to withdraw or insert the wire 50 in cooperation with the elastic device 40 to release energy; for example, the left region of fig. 6 depicts the situation.

It can be appreciated that when the operator operates the actuating handle 10 to move, the two metal spring plates 30 (or the three metal spring plates 30) can be configured to generate a plurality of pressing areas for the wire 50 in a segmented (or gradual) manner, so as to achieve the effect of saving the operation. And, the two first sections 31 (or three first sections 31) are matched with the structure of the first bending part 36, so that the pulling resistance of the wire 50 pressed by the tail end 37 of the first section can be improved; in addition, the combination of the shape of the tail end 39 of the second section 32 (or the second bending portion 38) pressing the end region of the wire 50 can significantly improve the fixing effect of the wire 50 (especially the wire with large wire diameter), and the contact area (or contact area) and contact force of the wire 50 and the conductive frame 20, thereby relatively increasing the conductive efficiency.

Typically, this improved structure of the wiring assembly for the terminal device has the following advantages over the older method:

1. The conductive frame 20, metal spring 30 and/or actuator handle 10 of the wiring assembly and related assembly structures have been redesigned. For example, the metal elastic sheet 30 forms a first curved arc portion 34 between the first section 31 and the base section 33, forms a second curved arc portion 35 between the second section 32 and the base section 33, and the second curved arc portion 35 combines the protruding piles 93, so that the entire metal elastic sheet 30 can generate (rotate) motion in response to the motion of the actuating handle 10; the actuating handle 10 is provided with a pivoting part 11, an operating part 12 and a pressing part 13, and is combined with a frame body 60; the parts of the elastic device 40, such as the first arm 41, the extension section 44, the second arm 42, the auxiliary section 45, are provided, which are obviously different from those of the prior art, and the conductive structure or the combination relation of the terminal device in the prior art is changed, so that the use and the operation of the terminal device are different from the old method.

2. Particularly, under the condition of not increasing the thickness of the metal elastic sheet, the wiring assembly is provided with a plurality of (or a plurality of) pressing mechanisms, so that the matching structure of the wiring assembly can provide enough pressing force to obtain the structure and the function of fixing the wire, thereby improving the situations that the force for pressing the wire is insufficient, the pressing is unstable, the wire is easy to deviate and shake (or is touched by personnel carelessly) and the poor contact is caused.

3. In addition, the combined structure state of the wiring assembly also removes the structure state that the lead is locked by using screws by using an old method or the follower body and the pressing arm are combined by jointly superposing one ends of two metal elastic sheets, improves the conditions that the structure of the prior art is complex, the assembly/processing operation and the operation are troublesome, time-consuming and labor-consuming, the production cost is relatively increased, and the like, thereby achieving the effect of improving the manufacturing, processing and assembling efficiency of the wiring assembly; and, provide more or bigger contact area and contact force, relatively raise the conductive efficiency and suitable for the structural style of effects such as the big, small-diameter wire, etc..

In summary, the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, but any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the scope of the present invention.
