Description

Improved structure of wiring assembly for terminal device

The present invention relates to a wiring assembly structure for a terminal device; in particular, it refers to a technique for establishing a plurality of pressing and fixing wires by the metal elastic sheet of the wiring assembly cooperating with the actuating handle to generate movement.

Metal components (or conductive elements) and shrapnel conductors (or metal shrapnel) enclosed in insulating housings (usually made of plastic materials) are used to press or connect the wires entering the terminals to form electrical connection or release. Wire termination devices or crimping terminals are known in the art. For example, CN 102204015 A "Electrical Connection Terminal", DE 29915515 U1, EP 2325947 A1, US 2013/0143433 A1 "CONNECTION TERMINAL", US 2014/0127932 A1 "ELECTRICAL CONNECTION TERMINAL", DE 10 2012 009 286 A1, US "53625 A1" The "GROUND CONDUCTOR TERMINAL" patent case, etc., provides typical examples.

This type of electrical connection terminal device usually includes an insulating housing; the housing has wire entry holes, allowing wires to be inserted into the interior of the housing. The casing also defines a cavity for assembling the conductive support (or conductive element) and the metal dome, so that the metal dome and the conductive element press the wire inserted into the casing to form contact or electrical connection. The electrical connection or contact state between the wire, the metal dome and the conductive element can only be released unless the personnel operates other tools to insert into the casing and push the metal dome.

One of the problems related to the structure and operation application of the combined structure of the conventional terminal device is that in the use situation of the pivoted wire (or large diameter wire) of the terminal device, after the wire is inserted, it will not be sufficiently fixed. The metal end of the wire is shifted or swayed due to force, or the wire is not stable due to metal shrapnel and conductive elements, or the wire is rotated and shifted due to inadvertent touch by personnel, resulting in poor contact safety.

In order to improve the above-mentioned pressing force and electrical conductivity safety or efficiency, the prior art has disclosed a method of locking wires with screws, or applying double-layer metal shrapnel or increasing the thickness of metal shrapnel and conductive elements to improve their compression. strength. The old method has also disclosed a technology of applying two metal shrapnel to combine a follower and a pressing arm; for example, DE 202017107202 U1, DE 202017107208 U1, US 2018/0006385 A1 "ELECTRICAL CONNECTION TERMINAL WITH A TWO-PART OPERATING ELEMENT" and other patents The case provides possible examples. In the described embodiment, one end of two metal dome sheets are superimposed and fixed on the follower body, and the follower is pressed by the pressing arm by the operator, so that the follower body drives the other end of the two metal dome pieces to form two pressing points for pressing the insertion wire, form of electrical connection.

As those who are familiar with this technique know, the operation of locking the wire or releasing the wire with a screw, or stacking one end of two metal shrapnel together to combine the follower, the structure of the pressing arm is more complicated, and the assembly or processing operation is also relatively complicated. It is troublesome, time-consuming, and relatively increases the production cost. Alternatively, increasing the number or thickness of the metal domes and conductive elements mentioned above not only increases the manufacturing cost, but also is laborious to operate; these situations are not what we expect.

Typically, these reference materials show the skills in the design and application of the structural combination of the terminal device; if the redesign considers the structural combination of the wiring assembly and the metal dome, so that the structure is different from the conventional one, it will be changed. It is different from the old law; in essence, it will also increase its scope of application.

We have found that an ideal terminal or wiring assembly structure must be able to overcome or improve the issues discussed above; it should also include the following design considerations, including:

1. Provide a wiring assembly with multiple pressing mechanisms without increasing the thickness of the metal shrapnel, so that the matching structure of the wiring assembly can provide sufficient pressing force, and allow it to be used in some electrical connection terminals to pivot large wires In the case of the diameter wire, the structure and function of the fixed wire can be obtained to improve the conventional structure. The strength of the wire is not enough, the pressing is not stable, the wire is easy (or accidentally touched by personnel) to produce deviation, shaking, resulting in poor contact safety, etc. situation.

2. The old method of locking wires with screws or using two metal shrapnels stacked together at one end to combine the structure of the follower and the pressing arm must be removed, in order to improve the conventional structure, which is more complicated, and the assembly/processing operations and operations are also more troublesome. Time-consuming, labor-intensive, relatively increasing production costs, etc., to achieve the effect of improving its manufacturing, processing and assembly efficiency; and, providing more or larger contact area and contact force, relatively improving electrical conductivity and suitable for large and small diameters The structural type of the action of the wire, etc.

None of these topics are taught or specifically disclosed in the aforementioned references.

That is, the main purpose of the present invention is to provide an improved structure of a wiring assembly for a terminal device, which provides a simple operation, labor saving, and the functions of increasing the electrical conductivity and the stability of the assembled wire; the wiring assembly comprises a conductive frame and at least a A combination of metal shrapnel.

Cooperate with the personnel to operate an actuating handle to control the entire metal shrapnel to generate (rotate) movement, so that the first section and the second section respectively form multiple suppressing mechanisms or suppressing areas for the wires entering the wiring assembly. Move or shake, the contact is unstable, which affects the conduction efficiency and safety.

The operating portion 12 has a mouth portion 14 for inserting a tool (eg, a screwdriver or the like) to operate the actuating handle 10 to move. In addition, teeth 15 are formed on the periphery of the mouth 14 or at least a partial area of the periphery, so that the actuating handle 10 can be operated by the hand of a person.

The conductors 50 constitute the above-mentioned multiple pressing mechanisms or suppressing regions, which improves the situation that the conventional conductors are easily displaced or shaken due to external force, the contact is unstable, and the conduction efficiency and safety are affected.

The figure also discloses that the casing 90 (or the chamber 99 ) is provided with a protruding post 94 , which is combined with an elastic device 40 . The elastic device 40 includes a base portion 43 assembled on the protruding post 94 and a first arm 41 and a second arm 42 (contacting the metal dome 30 or the base segment 33 ) protruding from both ends of the base portion 43 .

Therefore, when a person operates the actuating handle 10 to move back or back, the elastic device 40 releases energy, and the second arm 42 of the elastic device 40 pushes the metal dome 30 to move upward in the figure to allow the personnel to operate the withdrawal or insertion of the wire 50 Assignments; for example, the situation depicted in the left area of Figure 3.

It should be noted that when a person operates the actuating handle 10 to move, the structure of the metal dome 30 makes it possible for them to form a plurality of pressing areas on the wire 50 in sections (or gradually), which can achieve the effect of labor-saving operation. In addition, the first section 31 cooperates with the structure of the first bending portion 36 to improve the pull-out strength of the first section end 37 to suppress the wire 50; The shape of the folded portion 38) pressing the end area of the wire 50 can significantly improve the fixing effect of the wire 50 (especially the large diameter wire) and the contact area (or contact area) and contact force of the wire 50 and the conductive frame 20, and the contact force is relatively increased. Conductivity Efficiency.

Referring to Figure 4, a derivative embodiment of the metal dome 30 is shown. The first segment 31 of the metal dome 30 is inclined from the first curved portion 34 to the direction of the second segment 32 to form a straight extending shape. Compared with the above-mentioned embodiment (the first section 31 is formed with the first bent portion 36 ), the position of the tail end 37 of the first section 31 is closer to the tail end 39 of the second section 32 , so that the tail end of the first section 31 is 37 can directly press wire 50.

Please refer to FIGS. 5 and 6 , which show the structure of the wiring assembly using a plurality of metal domes 30 (the plurality of metal domes 30 ; for example, three or more metal domes 30 ) combined. The bimetallic dome 30 (or three metal domes 30 ) is arranged and assembled on the protruding pile 93 of the housing chamber 99 to form a reciprocating motion. The two metal domes 30 (or three metal domes 30 ) respectively have a first segment 31 , a second segment 32 and a base segment 33 connecting the first segment 31 and the second segment 32 ; two metal domes 30 (or three metal domes 30 ) ) of the base section 33 forms an overlapped pattern at least in a partial area. And, a first curved portion 34 is formed between the first segment 31 and the base segment 33 , and a second curved portion 35 is formed between the second segment 32 and the base segment 33 .

In a feasible embodiment, the first sections 31 of the bimetallic dome 30 (or the three metal domes 30 ) are respectively provided with first bending portions 36 , and at least two first sections 31 (or three first sections 31 ) ) to form a separation type, and make the tail end 37 of the first segment 31 extend obliquely toward the direction of the second segment 32 ; the second curved portion 35 of the bimetallic dome 30 (or three metal dome 30 ) combines the convex pile 93 (or around the convex pile 93), and the two second sections 32 (or the tail end 39 and/or the three second sections 32 close to the second section 32) are respectively provided with second bending parts 38, so that the The tail ends 39 of the two second sections 32 (or the three second sections 32 ) extend in the same direction as the tail end 37 of the first section, and at least the tail ends of the two second sections 32 (or the three second sections 32 ) The ends 39 form a separate pattern, which together constitute a plurality of suppressing mechanisms.

The left area of FIG. 6 shows that the metal dome 30 is in a released state, so that a person can operate the insertion operation of the wire 50 . When the operator operates the actuating handle 10 to make the pressing portion 13 press down the base section 33 of the metal dome 30, the tail ends 39 of the two second sections 32 will first press the wire 50 to form a fixation, and the first pressing area and the second pressing area will be established. zone; and, the elastic device 40 is made to store energy.

When the person continues to operate the pressing part 13 of the actuating handle 10 to press down the metal dome 30 (and the elastic device 40 continues to accumulate energy), the tail ends 37 of the two first segments 31 clamp the wire 50 to form a fixation, and a third pressing area is established , the fourth pressing area; for example, the bimetallic dome 30 shown in the right area of FIG. 6 establishes multiple pressing mechanisms.

Therefore, when a person operates the actuating handle 10 to move back or back, the elastic device 40 releases energy, and the second arm 42 of the elastic device 40 pushes the metal dome 30 to move upward in the figure to allow the personnel to operate the withdrawal or insertion of the wire 50 Assignments; for example, the situation depicted in the left area of Figure 6.

It can be understood that, when a person operates the actuating handle 10 to move, the structure of the two metal domes 30 (or the three metal domes 30 ) enables them to produce a plurality of pressing areas on the wire 50 in sections (or gradually). It can achieve the effect of labor-saving operation. In addition, the two first sections 31 (or three first sections 31 ) cooperate with the structure of the first bending portion 36 , which can improve the pull-out strength of the first section end 37 to suppress the wire 50 ; and, combining the second section 32 The tail end 39 (or cooperate with the second bending part 38 ) presses the shape of the end area of the wire 50, which can significantly improve the fixing effect of the wire 50 (especially the large wire diameter wire) and the contact area of the wire 50 and the conductive frame 20 ( or contact area), contact force, and relative increase in electrical conductivity.

Typically, compared to the old method, the improved structure of the wiring assembly used for the terminal device has the following advantages:

1. The conductive frame 20 , the metal dome 30 and/or the actuating handle 10 and related components of the wiring assembly have been redesigned for consideration. For example, the metal dome 30 forms a first curved portion 34 between the first segment 31 and the base segment 33 , a second curved portion 35 is formed between the second segment 32 and the base segment 33 , and the second curved portion 35 is combined to protrude The pile 93 enables the entire metal dome 30 to generate (rotate) movement in response to the movement of the actuating handle 10; Parts such as the first arm 41 and the extension section 44, the second arm 42 and the sub-section 45 are obviously different from those of the conventional ones, and also change the conductive structure or the combination relationship of the conventional terminal device, so that its use and operation are different. in the old law.

2. In particular, without increasing the thickness of the metal shrapnel, the wiring assembly has multiple (or more) pressing mechanisms, so that the matching structure of the wiring assembly can provide sufficient pressing force to obtain the structure and function of the fixed wire. , to improve the situation that the conventional structure does not have enough force to suppress the wire, the pressing is not stable, the wire is easy to shift (or due to inadvertent touch by personnel), and it sways, resulting in poor contact safety.

3. In addition, the combined structure of the wiring assembly also removes the old method of using screws to lock wires or using two metal shrapnel at one end to stack together to combine the follower and the pressing arm, which improves the comparison of conventional structures. Complex, assembling/processing operations and operations are more troublesome, time-consuming, laborious, and relatively increase production costs, so as to achieve the effect of improving its manufacturing, processing and assembly efficiency; and, providing more or greater contact area and contact force , It is a structural type that relatively improves the electrical conductivity and is suitable for large and small diameter wires.

Therefore, the present invention provides an effective improved structure of a wiring assembly for a terminal device, the spatial pattern of which is different from that of the prior art, and has incomparable advantages in the old method, which shows a considerable progress.
