Description

Compact wiring terminal

Technical Field

The invention relates to a wiring terminal, in particular to a compact front wiring terminal, which belongs to the technical field of electric connection.

Background

With the continuous development of technology, the performance requirements on infrastructure equipment in the industries of communication, photovoltaics and the like are higher and higher, and the requirements on the external dimensions of the wiring terminals are smaller and smaller.

The front-side wiring technology is a common option to cope with the miniaturization requirements of wiring terminals. Fig. 9 illustrates a conventional front screw terminal 900, which mainly includes a closed wire clamping frame 902, screws 903 and cam pressing pieces 909 fitted into the wire clamping frame, and a guide strip 910 for making electrical contact with the wire clamping frame 902, wherein the other end of the guide strip 910 is in contact with a conductive spring clip 911. The terminal adopts front wiring, a wire inlet 904 for connecting wires is formed on one side (front) of the screw of the wire clamping frame 902, and a tool for rotating the screw is also accessed from the front, namely, the cable connection and the screw operation are in the same horizontal plane. After a wire (not shown) enters the wire inlet 904 from the front, the screw 903 is rotated by a tool, and when the screw 903 is tapped downwards, the cam pressing block 909 in the wire clamping frame 902 is driven to pivot, and the wire is pressed on the guide strip 910, so that conduction is realized.

When conventional front screw wiring technology is used for the front wiring applications where PCB rack and equipment space is limited, the size of the terminals is correspondingly reduced due to the limited space, and the reduction in terminal size objectively results in a corresponding reduction in conductive cross-sectional area (e.g., narrowing of the tie bars). Therefore, the wiring capacity and the current capacity of the miniaturized wiring structure of the enclosed wire clamping frame and the guide strip are generally smaller. For example, a conventional front screw terminal supports only a maximum of 4 square (mm) ² ) About 30A, while practical applications would expect the wire connection capacity to be substantially unchanged in terminal sizeAnd the current capacity is greatly improved.

Other conventional front-side wiring technologies, such as a pull-back terminal based on a cage spring clip, and a direct-insertion terminal based on a spring and a key, also generally adopt a structure of a closed wire-clamping frame and a guide strip. In practical miniaturized applications, the problem of insufficient wiring capacity similar to the front screw wiring technology is also faced.

Therefore, improvements to the conventional technology are indeed necessary to solve the drawbacks.

Detailed Description

In the following description, the present invention is described with reference to the embodiments. One skilled in the relevant art will recognize, however, that the embodiments may be practiced without one or more of the specific details, or with other alternative and/or additional methods, materials, or components. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of various embodiments of the invention. Similarly, for purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the embodiments of the invention. However, the invention may be practiced without the specific details. Furthermore, it should be understood that the embodiments shown in the drawings are illustrative representations and are not necessarily drawn to scale.

The invention is further described below with reference to the accompanying drawings. Fig. 1 illustrates the overall structure of a compact front screw wiring assembly 100 according to one embodiment of the present invention. The front screw terminal assembly 100 includes a terminal frame structure 20 into which wires 4 are accessed at the front (wire-in side) of the terminal frame structure 20 and clamped by rotating screws 24. A conductive output is provided at the rear of the front screw wiring assembly 100. Note that the wire 4 itself is not a constituent part of the wiring assembly 100. Fig. 2 is a schematic view of the front screw terminal 100 of fig. 1 in a longitudinal section along C-C. Although not shown in the figures, it is understood that the front screw wiring assembly 100 may be housed in a housing, and that one housing may include one or more front screw wiring assemblies 100, as desired.

Fig. 3 is an exploded view of the front screw wiring assembly 100 shown in fig. 1. As shown in the drawing, the wire frame structure 20 of the front screw wire assembly 100 may include a hollow wire clamping operation frame 21 and a wire guiding frame 22 capable of being spliced together with the operation wire clamping frame 21 and communicating with an inner space. The front screw wiring assembly 100 may also include a cam block 23 and screws 24. Fig. 4A shows schematic views of two views of the wire clamping operation frame 21, and fig. 4B shows schematic views of two views of the wire inlet guide frame 22.

For convenience of explanation, when the wire clamping operation frame 21 and the wire guiding frame 22 are described with reference to fig. 1 to 3, the side facing the viewer is taken as the front side, the opposite side is taken as the rear side, and the left, right, up and down directions in the drawing are the left, right, up and down directions of the wire clamping operation frame 21 and the wire guiding frame 22 shown in the drawing. However, those skilled in the art will appreciate that such azimuthal expressions are not limiting.

In the discussed wire frame structure 20, the wire clamping operation frame 21 may include a main body frame 210 and a pair of connection plates 212 provided with circular arc recesses 211 formed by extending the front and rear walls of the main body frame 210 to the right. Threads (not shown) are provided on the upper wall of the main body frame 210 for the screws 24 to be screwed into the inside of the main body frame 210.

In the wire frame structure 20 in question, the incoming wire guide frame 22 is made of an electrically conductive material and includes an upper incoming wire connection portion 220 for making electrical connection with a front-side accessed wire, and a lower guide outlet portion 221 for plugging or otherwise making electrical connection with other electrical components. As shown in fig. 3, the incoming line connection part 220 may have a U-shape including a front wall, a rear wall, and a connection section 223 connecting right ends of the front wall and the rear wall. The flow guide tap 221 may include a pair of bases 224 formed to extend downward from each of the front and rear walls of the inlet connection 220, and the pair of bases 224 may gradually converge with each other. The flow guide outlet 221 is thus formed as an integrated structure with the inlet connection 220. At the end of the base 224, a comb-like insertion structure is further formed. The left edges of the front wall and the rear wall of the incoming line connection part 220 may be respectively protruded with an arc body 222 capable of being spliced in the arc recess 211. Referring again to fig. 2, a stop structure 11 may also be provided in the incoming guide frame 22. After the lead 4 is inserted into the incoming wire guide frame 22, the lower surface of the lead can be contacted with the stop structure 11, so that the plug wire is prompted to be in place.

The above-described wire frame structure described in connection with fig. 1-3 helps to increase the wire capacity compared to the structure of the wire clamping frame with the addition of the guide strip shown in fig. 9.

In the wire frame structure shown in fig. 1-3, when the diameter of the incoming wire 4 is substantially equal to the distance between the front wall and the rear wall of the incoming guide frame 22, the incoming wire is in conductive contact with the three conductive sides (front wall, rear wall, connection section 223) of the incoming connection 220. Since the conduction of the current follows the principle of the shortest path, and the base 224 of the tapping 221 is an integrated structure extending from the front and rear walls of the incoming wire connection 220, the current on the incoming wire is conducted to the base 224 of the tapping 221 via the front and rear walls of the incoming wire connection 220. In the structure of the wire clamping frame with the additional guide strip shown in fig. 9, the current basically flows from the wire inlet wire directly to the guide strip 910, and then continues to be conducted along the guide strip 910. Although in this case the incoming wire is also in contact with the front and rear walls of the wire clamp 902, the current is not primarily conducted through the front and rear walls of the wire clamp 902 according to the shortest path principle. Accordingly, the wire frame structure 20 of the embodiments of the present application achieves a larger effective conductive cross section with comparable dimensions compared to the conventional wire terminal shown in fig. 9, thus improving wire capacity.

When the front screw wiring assembly 100 shown in fig. 1-3 is installed, the arc recess 211 on the wire clamping operation frame 21 and the arc body 222 on the guide frame 22 can be spliced together to form an approximately closed wiring groove between the wire clamping operation frame 21 and the wire feeding guide frame 22, the cam pressing block 23 is installed into the inner space of the wire feeding guide frame 22 and the wire clamping operation frame 21 from above the guide frame 22, and the upper end of the cam pressing block 23 is lapped on the connecting plate 212 of the wire clamping operation frame 21. The cam block 23 is free to rotate in the above-described approximately closed wiring groove.

The following exemplary description is of the use of the front screw wiring assembly 100 shown in fig. 1-3. As shown in fig. 4-5, when the terminal with the front screw wiring assembly 100 is wired, the screw 24 can be reversely rotated to the highest position by a tool (such as a screwdriver), the cam pressing block 23 is in a free state, the lead 4 is inserted from the upper side of the incoming wire guiding frame 22, the guiding frame is provided with the stop structure 11, the lead 4 can be inserted into the position where the lower surface is in contact with the stop structure 11, after the lead 4 is inserted, the screw 24 is screwed by a starter to drive the cam pressing block 23 to rotate, the lead 4 is pressed on the incoming wire guiding frame 22, conduction is realized, and the upper end of the cam pressing block 23 is always clung to the connecting plate 212 in the rotating process of the cam pressing block 23.

As shown in fig. 6, when the terminal with the front screw connection assembly 100 is withdrawn, the screw 24 is first loosened by the lifter to the highest position, and when the cam block 23 is in a free state, the wire is directly pulled outwards, so that the withdrawal is completed. It should be appreciated that a stop may be provided on the housing that houses the front screw wiring assembly 100 in order to prevent the screws 24 from loosening when the wires are untwisted.

Although one embodiment of the present invention is described in connection with fig. 1-6, the implementation of the present invention is not limited in this regard. For example, variations and alternatives set forth below are also contemplated by the present disclosure.

Fig. 1-6 illustrate a front screw wiring assembly 100, with the housing (typically made of an insulating material) not shown. It should be understood that the form of the housing and the number of wiring assemblies received by the housing may be selected and adjusted according to the needs of the application.

Fig. 1 to 3 show a frame structure formed by splicing the wire clamping operation frame 21 and the wire inlet guide frame 22. In the case of miniaturization, the frame structure is beneficial to guaranteeing the through-flow capacity and strength at the same time. Specifically, the wire guide frame 22 may be made of a high conductive material such as copper to ensure the through-flow, and the wire clamping frame 21 may be made of a high strength material such as steel to ensure the required strength even in a small size. However, it should be understood that the present invention is not limited thereto, and the wire clamping operation frame and the wire guiding frame may be formed as an integrated structure, i.e., the functions of wire clamping, wire feeding, and guiding are implemented in a single frame structure, in case that the requirements of material strength and conductivity are satisfied. It will also be appreciated that for two-and multi-piece implementations of the frame, schemes other than those of fig. 1-3 may be employed as desired. For example, a modified embodiment may be implemented by splicing an upper frame body and a lower frame body, where the upper frame body is provided with a screw inlet and a wire inlet, which substantially correspond to the structure and function of the wire clamping operation frame 21 and the wire inlet connection portion 220, and the lower frame body substantially corresponds to the structure and function of the flow guiding and receiving portion 221.

With respect to the splicing manner of the two-piece structure of the wire frame structure, although fig. 3 shows that the connection plate 212 with the circular arc recess 211 is formed on the wire clamping frame 21 and the circular arc body 222 is formed on the wire guiding frame 22, it should be understood that this technical means is only one of various means of splicing the wire clamping operation frame 21 and the wire guiding frame 22, and that there are various alternative or equivalent manners. In an embodiment, the wire clamping frame 21 may not have a laterally extending connection plate thereon, but a recess structure for splicing is directly formed in the front and rear sidewalls of the wire clamping frame 21. In another embodiment, an arc body may be formed on the wire clamping operation frame 21, and an arc recess may be formed on the wire inlet guide frame 22. In another embodiment, the structures used to splice with each other may not be circular arcs and corresponding depressions, but any other structure that enables a splice (e.g., various forms of interlocking engagement).

Although the stop structure 11 in the flow frame 22 is shown in fig. 2 to occupy less area than the carry area of the wire, in another embodiment, the stop structure 11 may be provided to be equal to or greater than the area of the wire entrance to ensure adequate contact with the end of the inserted wire, further ensuring throughflow capability.

Although the flow-directing outlet 221 of the front screw wiring assembly 2 is shown in fig. 1-6 as having a mating structure in the form of a pair of comb teeth, this is merely one example. The front screw wiring assembly of the present invention is not limited thereto, and may employ any suitable plug-in configuration (e.g., various types of pins, tabs) for making electrical contact at the rear end of the wiring assembly, or may instead employ any specific plug-in configuration, employ the formation of conductive strips at the distal end of the fluid-conducting outlet, and then spring clips to draw current/signals from the rear end of the front screw wiring assembly. In some embodiments, the plug structure may be formed extending directly from the front and rear walls of the incoming line connection 220 without a transition portion such as the base 224 (e.g., the plug structure described below in connection with fig. 7A-7C).

Further variant embodiments should not be limited to screw wiring schemes, but may employ various forms of incoming wire guide structures.

For example, for a spring and button based in-line terminal, spring tabs and buttons may be placed in a spliced or integral wire frame structure and a current-carrying tap extending from the front and rear sidewalls may be formed in the wire frame structure to form a current-carrying path from the front and rear sidewalls to the current-carrying tap.

Fig. 7A-7C schematically illustrate a wire connection assembly (not shown) adapted for use in an in-line terminal, wherein the wire clamping member includes a spring piece 702 and a key 701, the key 701 being depressed by an operating tool, the spring piece 702 being deformed to release a wire clamped by the spring piece. The two walls of the wire frame 703 extend downward to form a pin-type current-guiding and outputting structure 704, and when the wires are connected in and electrically contacted with the two walls of the wire frame 703, the current is mainly conducted to the current-guiding and outputting structure 704 along the two walls. It will be appreciated that increased flow capacity is achieved when the 4 flow-out structures 704 provide an overall cross-sectional area that is greater than the cross-sectional area of a conventional flow-bar inserted into the frame.

For example, for a pullback terminal based on a cage spring clip, the cage spring clip may be placed in an integral or spliced wire frame structure and the shunt tab extending from the front and rear sidewalls formed therein, thereby forming a current transfer path from the front and rear sidewalls to the shunt tab.

Fig. 8A-8D schematically illustrate a wiring assembly (not shown) suitable for use with in-line terminals wherein the wire clamping member includes a cage spring clamp 801 with a clamping opening 802 formed in the cage spring clamp 801. A mounting bar 805 is also formed in the wire frame for mating with the cage spring clip 801. When the cage spring clamp 801 is pushed from the right to the left using a tool (arrow shown) in connection with fig. 8B, the spring and fitting bar 805 are decoupled, the wire can be inserted from the left side of the fitting bar 805, and then the tool is removed, and the restoring force of the cage spring clamp 801 clamps the inserted wire against the fitting bar 805. The two walls of the wire frame 803 extend downward to form a pin-type current-guiding and outputting structure 804, and when the wires are connected in and electrically contacted with the two walls of the wire frame 803, the current is mainly conducted to the current-guiding and outputting structure 804 along the two walls. It will be appreciated that increased flow capacity is achieved when the 4 flow-out structures 804 provide an overall cross-sectional area that is greater than the cross-sectional area of a conventional flow strip inserted into the frame.

In some variations, the pinching and releasing operations are accomplished without external tools, and thus no tool access for tool access is provided in the wiring scheme.

The compact wiring terminal provided by the invention eliminates the bottleneck affecting the current capacity in a miniaturized wiring scene by improving the structure of the wiring frame on the basis of the prior wiring technology, improves the wiring capacity and the current capacity, and achieves the aims of miniaturization and high performance.

While the basic concepts have been described above, it will be apparent to those skilled in the art that the foregoing disclosure is by way of example only and is not intended to be limiting. Although not explicitly described herein, various modifications, improvements, and adaptations of the present application may occur to one skilled in the art. Such modifications, improvements, and modifications are intended to be suggested within this application, and therefore, such modifications, improvements, and modifications are intended to be within the spirit and scope of the embodiments of the present application.
