Description

Binding post and be used for binding post's conductive component

Technical Field

The present invention relates to a terminal, and more particularly, to a tool-less terminal and a conductive assembly for the terminal.

Background

Electrical terminals are known in the electrical industry. Electrical terminals may be used to connect a conductor, such as a wire, to another conductor. Electrical terminal types have various different mechanisms for securing electrical wires. Generally, electrical connection terminals apply a clamping force to the leads of the wires within the electrical connection terminal by means of a set screw. This type of electrical connection terminal requires the user to first loosen the set screw in order to insert the lead into the terminal, which can be cumbersome and cumbersome. In addition, the fixing screws need to be tightened when fixing the lead, which may also be difficult depending on the mounting position or orientation of the electrical connection terminal. There are also known electrical terminals which produce a clamping effect on the lead of the wire by using an electrically conductive spring. To actuate the spring, an actuating tool, such as a screwdriver, needs to be inserted into the actuating shaft to open the terminals. In doing so, the end of the screwdriver tensions the spring to open the grip. Electrical connection terminals of the above type have the following disadvantages: tools are always required to actuate the clamping mechanism in electrical terminals. In addition, the shell of the conventional connecting terminal is usually of an integrated structure, the processing and mounting processes are complex, and the production efficiency is relatively low.

Detailed Description

In order that the objects, features and advantages of the present invention will be more readily understood, preferred embodiments of the present invention will be described in detail hereinafter with reference to the accompanying drawings. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely used to describe the nature and spirit of the present invention.

Fig. 1 shows a perspective view of a unipolar connection terminal according to a first exemplary embodiment of the invention. The terminal 1 is symmetrical in its longitudinal direction. By way of example, the terminal 1 may have an elongated rectangular block-shaped housing 4 having two opposite input and output ends 1a,1b at its longitudinal ends. Each of the input and

output terminals

1a and 1b has an end opening 2 for inserting a wire (not shown in the drawings). The end opening 2 is provided with a passage 2a, the passage 2a leading into the interior of the terminal 1, and the

conductive elements

8,9 are located in the interior of the terminal 1. The first and second

conductive elements

8,9 are configured to make electrical contact with the leads of the wires when the wires are inserted through the end opening 2 into the passage 2a and engaged with the clamping mechanism formed by the first and second

conductive elements

8, 9.

On top of the terminal 1, an actuating member 3 is provided for each end opening 2. The actuating member 3 may, for example, be a lever pivotally mounted on the top side of the housing 4 of the terminal 1. An actuating member 3 is located above each of said end openings 2, the actuating member 3 being movable and pivotable between an open position and a closed position, the two actuating members 3 being shown in different positions and orientations in fig. 1.

According to the exploded view of the terminal 1 shown in fig. 2, the external structure of the terminal 1 comprises a housing 4, an actuating member 3 and a carrying member 7. The periphery of the end opening 2 may be provided with a chamfer providing a guiding action for the wire when it is inserted. The cross-section of the end opening 2 or the passage 2a may be square or circular and is dimensioned according to the wire diameter which may be required for the load capacity of the terminal 1. As shown in fig. 2, the connection terminal 1 is basically composed of a combination of an upper subassembly 10 and a lower subassembly 20. In particular, the upper subassembly 10 comprises the housing 4 and the actuating member 3, while the lower subassembly 20 comprises the holding member 7 and the first and second

conductive elements

8, 9. The housing 4, the actuating member 3 and the holding member 7 may be made by injection moulding using a polymer material which provides sufficient strength, heat resistance and insulating capability.

Fig. 3 and 4 show the structure of the housing 4 in the upper subassembly 10. The housing 4 has a hollow structure as shown in the figure. The housing 4 is provided with a top hatch 4a and a bottom hatch 4 b. The bottom hatch 4b is substantially rectangular and allows direct access to the interior 4c of the terminal 1. The bottom hatch 4b may be closed by a cover member provided by a holding member 7. On top of the housing 4, above each of the input 1a and output 1b, there is a hinge member 42. Each hinge member 42 may be integrally formed with the housing 4, and extend longitudinally toward the center of the housing 4 and parallel to the sides of the housing 4. The top hatch 4a of the housing 4 presents an H-shape with a relatively spacious central channel 41a and four peripheral channels 41 b. Furthermore, a recessed area 43 may be provided above each of the input 1a and output 1b for receiving a portion of the actuating member 3 located on the housing 4.

Fig. 4 shows the bottom surface of the housing 4. Each hinge member 42 is provided with two spaced apart guide rails 42b extending parallel to the hinge member 42 as viewed from the bottom. One end of each guide rail 42b is open toward the center, and the other end is terminated with a rounded corner 42 c. The actuating member 3 is slidably and pivotably engaged with the guide rail 42 b.

Fig. 5 and 6 show a top perspective view and a bottom perspective view of the actuation member 3. The actuating member 3 has a grip portion 31 and two swing arms 32 supported from both sides of the actuating member 3, and dimples (not shown in the drawings) may be preferably provided on the grip portion 31 to improve contact friction between the user's fingers and the grip portion 31. The rocker arms 32 extend from one side of the actuating member 3, with a gap 30 formed between the rocker arms 32. An inwardly projecting pivot member 33 is provided on the inner side of each rocker arm 32, as shown in the drawings. The pivot member 33 extends approximately half way along the length of the rocker arm 32 and has a pivot portion 33a, such as a rounded tip, configured for pivotal and sliding engagement with a guide track on the underside of the hinge member. Each rocker arm 32 is also provided with a rocker arm tip 32a on its end.

The actuating member 3 may be detachably mounted on the housing 4 in the following manner. Fig. 7 is a sectional view taken along line a-a in fig. 1. As shown in fig. 7, the rocker arms 32 are slidably engaged with the hinge members 42 adjacent to and corresponding to the guide rails 42b, while the hinge members 42 are passed through the gaps 30 between the rocker arms 32, so that the rocker arms 32 are slidably moved into the two peripheral channels 41 b. The rocker 32 extends downwardly into the housing 4 with the pivot member 33 located below the hinge member 42, with each pivot portion 33a engaging a guide rail 42b below the hinge member 42. When the actuating member 3 is mounted, the actuating member 3 can slide along the guide rail 42b below the hinge member 42 and can pivot about the pivot portion 33a at the same time. According to fig. 8, the actuating member 3 is now in a different position with respect to that shown in fig. 7, while fig. 7 shows the actuating member 3 in a closed position. In particular, fig. 8 shows the actuating member 3 in an open position, in which the actuating member 3 is moved towards the centre direction and is tilted upwards. As described above, when the two actuating members 3 are mounted to each of the input 1a and the output 1b, the assembly of the upper subassembly 10 is completed.

Figure 9 shows the brace member 7 in the lower sub-assembly 20. The holder member 7 includes a top cover member 71 and a frame-like structure thereof, a bottom cover member 72, and a support member 73 formed integrally with the cover member 71. The bottom cover member 72 has a shape corresponding to the bottom hatch 4 b. The bottom cover member 72 serves as a closing member that shields the bottom hatch 4 b. The top cover member 71 is positioned so that once the retainer member 7 is fully inserted into the housing 4 from the bottom hatch 4b, it aligns with and covers the central slot 41a, as shown in fig. 1, and a guide slot 4d (see fig. 2) may be provided in the block housing 4 for sliding engagement with the side wall 73 of the retainer member 7 to facilitate alignment and insertion of the retainer member 7 into the housing 4.

The retainer member 7 also comprises a single side wall 73 connecting the bottom cover member 72 and the top cover member 71 and giving the retainer member 7a c-shaped side profile. A positioning member 74 protrudes from the side wall 73, and is disposed at a position between the top cover member 71 and the bottom cover member 72, so that a first mounting passage 73a is formed between the bottom cover member 72 and the positioning member 74, and a second mounting passage 73b is formed between the positioning member 74 and the top cover member 71.

According to fig. 9 and 10, the first conductive element 8 is mounted in the first mounting channel 73a in the manner shown. Advantageously, one or more depressions 8a may be provided on the first conductive element 8 such that a friction fit is created between the first conductive element 8 and the first mounting channel 73a, thereby holding the first conductive element 8 in place during assembly. The first conductive element 8 may be an elongate metal strip having a substantially "C" shaped bend 81 providing two offset ends 82 as shown. The "C" shaped flex 81 of the first conductive element 8 provides resilience to counteract deformation of the first conductive element 8 such that when the biased end 82 is compressed downwardly by the actuation member 3, a biasing force is generated to resist the downward pressure. When the actuating member 3 is released, the biasing force lifts the contact end 81 upwards and returns to its uncompressed state. The biased end 82 is arranged to contact the wire when engaged therewith. Preferably, the end 82a of the biased end 82 may be slightly bent upward for achieving a substantially perpendicular contact angle with the wire, thereby providing maximum gripping force on the wire. The first conductive element 8 is also provided with a recess 83 adjacent to the "C" shaped bend 81, the recess 83 being obtainable by pressing or bending the first conductive element 8. Along the length of the first conductive element 8, each recess 83 is disposed between the respective offset end 82 and the "C" -shaped inflection 81.

The second conductive element 9 is a flat metal strip having two opposing contact ends 92, which contact ends 92 are folded down to form two substantially vertical bends 91, as shown in fig. 10. Unlike the first conductive element 8, the second conductive element 9 may be substantially rigid or inflexible. Preferably, each contact end 92 may have a serrated edge (not shown) for promoting a gripping force on the wire. The second conductive element 9 may be made of a conductive material (for example, a metallic material) different from that of the first conductive element 8, the second conductive element 9 being mounted on the supporting member 7 in the manner described below. Advantageously, a second conductive element 9 can be inserted in the second mounting channel 73b of the supporting member 7, and on the bottom face of said top covering member 71 there can be provided a mounting seat 75 corresponding to said second conductive element 9, for fixing the position of said second conductive element 9 during assembly. Similarly, one or more depressions 93 may be provided on the second conductive element 9 for forming a friction fit between the second conductive element 9 and the second mounting channel 73 b. When the first and second

conductive elements

8,9 are mounted in the

respective mounting channels

73a, 73b of the supporting member 7, the contact ends 92 of the second conductive element 9 are positioned above the two offset ends 82 of the first conductive element 8. In particular, the end 82a of the offset end 82 is located within the span of the two contact ends 92 of the second conductive element 9. Whereas in each

end

1a,1b the offset end 82 of the first conductive element 8 and the contact end 92 of the second conductive part 9 together form a clamping portion 6 which can be actuated by the actuating member 3.

The positioning member 74 may also act as a divider within the housing 4 for blocking the passage of space between two opposing input and output ends 1a,1b to prevent wires at one end from directly contacting wires in its opposing end.

Referring again to fig. 2, guide means may be provided within the housing 4 for guiding the insertion of the lower sub-assembly into the housing 4. The bottom cover 72 may conceal the bottom opening 4b when the lower sub-assembly 20 has been fully inserted. At the top of the housing 4, an upper cover 71 may cover the central portion 4c of the top opening 4 a.

Preferably, fastening means such as hooks 76 may be provided on the lower sub-assembly 20, and the corresponding slots 44 may be mutually engageable with hooks 76 provided on the housing 4. Each catch 76 provided on the bottom cover 72 engages with a slot 44 provided on the housing 4. The fastening means is arranged such that the assembled terminal cannot be disassembled without the use of tools. Alternatively, the sub-assembly 20 may be secured to the housing 4 using other conventional fastening means, such as screws or by interference fit.

The following is a description of the manner of operation of the terminal 1.

According to the above-described terminal 1, each actuating member 3 is movable between a closed position and an open position. In the closed position, as shown in fig. 7, the actuating member 3 is substantially flush with the top of the housing 4, and the pivot portion 33a pivotally engages a fillet 42c at the end of the guide groove 42b, thereby allowing the actuating member 3 to pivot about the fillet 42 c. The contact end of the first conductive element 8 is biased upwards towards the rocker arm 32 and holds the actuating member 3 in the closed position, such that the first conductive element is provided with an upwards curve on each of said contact ends.

When a lifting force L is applied to the clamping portion 31 of the actuating member 3, the actuating member 3 starts to rotate in a clockwise direction, as shown in fig. 8, the pivoting movement of the actuating member 3 causes the rocker 32 to swing downwards and press against the first conductive element 8, the rocker tip 32a then being located above the biasing end 82, as shown in fig. 11.

Referring to fig. 12, further pivotal movement of the actuating member 3 causes the rocker arm tip 32a to slide from the biased end 82, ratcheting into the recess 83 provided on the first conductive element 8, while compressing the first conductive element 8. The rocker arm tip 32a of the actuation member 3 may be pointed or shaped such that it corresponds to the contour of the recess 83 provided on the first contact element 8. The rocker arm tip 32a may also be advantageously rounded to reduce wear and provide a smoother sliding movement over the recess 83 during operation.

Based on the engagement between the rocker arm tip 32a and the recess 83, the rocker arm tip 32a cannot overcome the frictional force formed in the recess 83, thereby causing the pivot portion 33 to slide forward in the direction D. At this time, the rocker arm tip 32a functions as a fulcrum when pressed against the recess 83 of the first conductive member 8. The pivoting part 33 continues to slide along the guide channel 43, the stop 34 on the actuating member 3 abutting the cover member 71. The cover member 7 then prevents the actuating member 3 from sliding and pivoting further. The actuating member 3 is then in the open position. When the rocker 32 compresses the first conductive element 8 to a certain extent, the clearance formed between the contact end of the first conductive element 8 and the end of the second conductive element 9 is sufficient to accommodate the lead of the inserted wire.

In the open position, the upward force of the first conductive element 8 causes it to abut the rocker arm tip 32a of the actuating member 3, thereby pushing the pivot portion 33 upward against the guide slot 42 b. In this position, the upward force is substantially perpendicular to the guide channel 42b, thereby generating a friction force sufficient to keep the actuating member 3 in the open position. This facilitates the user to insert the wire into the terminal 1 without the need to manually hold the actuator member 3 in the open position while inserting the wire.

When the actuating member 3 is in the open position, the lead of the wire can then be inserted into the terminal 1 through the passage 2a and to the clamping portion 6, the support 7b then blocking further insertion of the wire. As shown in fig. 12, the lead is located between the offset end 82 of the first conductive element 8 and the contact end 92 of the second conductive element 9. Moving the actuation member 3 in the opposite direction L' causes the actuation member 3 to pivot about the rocker tip 32a, causing the pivot portion 33 to slide backwards on the guide slot 42b until the pivot portion 33 reaches the fillet 42 c. When the first conductive element 8 is biased upwardly, the actuating member 3 pivots about the pivot 33 and the biased end 82 pushes the lead wire of the wire upwardly against the contact end 92, thereby creating a clamping effect on the lead wire. Preferably, the contact end 92 and the offset end 82 will generate sufficient friction to secure the lead in the terminal 1. By lifting the actuating member 3 to the open position, the lead of the wire can then be released from the terminal 1 by removing the clamping effect of the first and second

conductive elements

8,9 on the lead.

As shown in fig. 13, the terminal 1 may be formed in two or more arrays, which may depend on specific requirements. The terminal strip may be composed of an array of ten or more terminals, wherein a plurality of said housings 4 may be formed in one piece.

Fig. 14 and 15 each show a terminal 200 according to a second embodiment of the present invention. The connection terminal 200 includes at least one connection unit 210, and may be composed of 3 to 5 connection units 210 arranged in parallel, for example. Each of the wiring connection units 210 generally includes a detachable housing 201, two oppositely disposed actuating members 250, and a conductive assembly 230 disposed therein.

The housing 201 includes a first end 211 and a second end 212 provided at the head and tail ends, and a connecting member 213 connecting the first end 211 and the second end 212. The first end part 211 and the second end part 212 are respectively provided with a hollow port 214 for wire connection. The other of the ports 214 of the first end member 211 and the second end member 212 is provided with a C-shaped notch 215. The actuating members 250 are mounted to the upper portions of the first and

second end pieces

211 and 212, respectively. Similar to the first embodiment, an actuating member 250 is located above each of the ports 214, the actuating member 250 being pivotally mounted to the hinge member 216 atop the first end piece 211 and the second end piece 212. The actuating member 250 is movable and pivotable between an open position and a closed position. As shown in fig. 15, the actuating member 250 may be in different pivotal positions. The pivotal connection of the actuating member 250 and the hinge member 216 on the first end piece 211 and the second end piece 212 is based on substantially the same mechanical structure and principle as the previous embodiments, and therefore will not be described herein.

The first end part 211 and the end part of the hinge component 216 of the second end part 212 are provided with a first hook 217a extending outwards, and the first hook 217a is arranged to be clamped with a first buckle 217b which is a square through hole on the connecting part. The port 214 of the first end member (i.e., the first plug port) is further provided at an upper end thereof with a slide guide groove 218 connected to a first hook 217. The edge of the C-shaped recess 215 is provided with a locking groove 219 for connecting the connecting part 213, and the lower end of the C-shaped recess 215 is provided with a second locking hook 220b having a square through hole, which is configured to be locked with a second locking hook 220a at a corresponding position on the connecting part 213.

The two ends of the top wall 224 are respectively provided with the first catch 217b extending outward, and the first catch 217b moves along the sliding guide slot 218 and finally catches the first catch 217a, so that the first end part 211, the second end part 212 and the connecting part 213 are tightly connected together.

The second end part 212 is symmetrically disposed with respect to the first end part 211, so that the structure of the second end part 212 is substantially the same as that of the first end part 211 (e.g., has a second plugging port, etc.), and thus the description will not be repeated.

As shown in fig. 16, the connecting member 213 has a hollow structure, and includes a bottom wall 221, a left side wall 222 and a right side wall 223 provided on both sides of the bottom wall 221, and top ends of the left side wall 222 and the right side wall 223 are connected by a top wall 224. Returning to fig. 14, the top wall 224 is substantially flush with the top ends of the first and

second end members

211, 212.
