Detailed Description

Because the diameter of the electric wire in the metering box is large, the on-site bending is inconvenient, and therefore, the traditional parallel wire wiring terminal brings difficulty to the design of the parallel box body designed by the applicant. In addition, other structural designs of the parallel line wiring terminal also have many unmatched aspects with the parallel metering box designed by the applicant.

The multi-directional wiring terminal can be applied to wiring components serving as main wires and branch wires in the metering box, and can be fixed at a specific position of the metering box, for example, a position which is located below the circuit breaker and close to a side plate of the metering box. Generally, more than one connection terminal in the metering box can be used, for example, as an electric energy leading-in connection part for electrically connecting an externally-introduced electric wire with an existing trunk electric wire or branch electric wire in the metering box, and as an electric energy leading-out connection part for mechanically and electrically coupling the trunk electric wire and the branch electric wire in the metering box.

An electric energy metering device, a circuit breaker and a wiring terminal are usually arranged in the metering box. The electric energy metering device is usually arranged at the upper part of the metering box, the circuit breaker and the wiring terminal are usually positioned at the middle and lower parts of the metering box, and the wiring terminal is usually arranged below the circuit breaker.

Multidirectional binding post in this application can realize that arbitrary direction electric wire gets into to and parallel or vertical direction's electric wire is derived, thereby wiring operation when easy to assemble, make the wiring of batch meter, especially the wiring of block batch meter save time more.

Fig. 1 is an assembly view, fig. 2 and 3 are exploded views, and fig. 4 is a partially exploded view illustrating a structure of a connection terminal according to an embodiment of the present application. Referring to fig. 1 to 4, a wire connecting terminal in one embodiment of the present application may include an insulative housing 100, and a wire connection fixing structure 200 disposed in the insulative housing. The insulating housing 100 may have a base 101 and an upper cover 102, wherein the base 101 may have a recess 1010 for accommodating a portion of the wire connection fixing structure 200, for example, a small portion of the wire connection fixing structure, and the upper cover 102 may have a chamber 1020 for accommodating a large portion of the wire connection fixing structure, and the recess and the chamber may individually or together form an accommodating space.

The wire connecting wire fixing structure 200 may include a first conductive presser 201, a second conductive presser 202, and a bracket 203 that cooperates with the first conductive presser 201 and the second conductive presser 202 and defines positions of the first conductive presser 201 and the second conductive presser 202. The frame 203 is generally U-shaped and includes a base 2031 and two

side plates

2032, 2033, with an open end 2034 opposite the base for the first and second

conductive presses

201, 202 to enter a space 2035 defined by the two

side plates

2032, 2033 of the body. The surfaces complementary to the

side plates

2032, 2033 can be in a fully open configuration, as shown in fig. 2 and 3. The first conductive press 201 and the second conductive press 202 may be slidably fitted to the bracket 203 along the long axis L1 of the bracket 203 such that the first conductive press 201 is fitted between the second conductive press 202 and the base plate 2031.

The

side plates

2032, 2033 of the rack 203 have

interior grooves

2032A and 2033A. The two inner grooves can be symmetrically arranged and have the same size and shape. The inner tank has a proximal end adjacent the base plate and a distal end distal from the base plate, e.g., 2032B at the proximal end and 2032C at the distal end of the inner tank 2032A. The stent defines a long axis direction L1, a first width direction W1 and a second width direction W2, as shown in fig. 2 and 3.

Fig. 6A and 6B are perspective views of the first conductive presser 201 from different angles. As shown in fig. 6A and 6B, the first conductive follower 201 includes a first surface 2011 having a plurality of fingers 2013 and a second surface 2012 having a plurality of fingers 2014. Among them, the pressing claws 2013 may be two, three, four, five or more, and may have the same configuration or different configurations, for example, the middle three pressing claws have a larger size in the first width W1 direction, and the pressing claws on both sides have a smaller size in the first width W1 direction. Alternatively, for example, the intermediate portions of the pressing claws each have the same curvature or less to press the exposed portion of the electric wire. Wherein the pressing claw and the bottom plate of the bracket define a first wire channel in the first width direction W1, for example, for a trunk wire to pass through and to be pressed between. The number of prongs 2014 may be the same as the number of clamping jaws 2013 to facilitate manufacturing, or may be more or less than the number of clamping jaws, such as two, three, or four. Taking four holding claws as an example, the size of each holding claw in the first width direction W1 may be the same or different, for example, two holding claws located at the middle position may be slightly larger than holding claws located at both sides in the first width direction. Wherein, the width of the two support claws positioned in the middle is larger than the diameter of the exposed part of the electric wire.

Fig. 7A and 7B are perspective views of the second conductive pressing element 202 at different angles in the embodiment. Fig. 7C and 7D are different perspective projection views of an embodiment of the second conductive compression element 202. As shown in fig. 7A and 7B, the second conductive follower 202 includes a first surface 2021 that is substantially flat, and a second surface 2022 having a plurality of fingers 2024. The plurality of claws 2024 are provided in two rows each of which is provided with four in the first width direction W1 in the second width direction W2. The spacing of the two rows of jaws in the second width direction W2 may be at least the diameter of the exposed portion of the wire so that the exposed portion of the wire may extend into the passageway 2023 between the two rows of jaws in the first width direction W1. Further, the distance S1 between the opposing surfaces of the two claws in the middle of each row of claws is set smaller than the diameter of the bare part of the branched electric wire, and in some embodiments, the distance S2 between the outer side surfaces of the two claws is set larger than the diameter of the bare part of the electric wire. So that the exposed part of the wire can be held above the two jaws. The height of the middle two clamping jaws can be larger than the diameter of the exposed part of the electric wire, so that the exposed part of the branch electric wire supported on the middle clamping jaw and the exposed part of the electric wire extending between the two rows of clamping jaws cannot interfere with each other.

Wherein the catch of the first conductive presser member and the catch of the second conductive presser member define a second wire passage in the first width direction W1 of the bracket and a third wire passage in the second width direction of the bracket. The second wire passage and the third wire passage may be oriented substantially perpendicularly.

It should be understood that the first and second surfaces of the first conductive compression element may have no fingers or detents, or only fingers or detents. And the second surface of the second conductive follower may have no fingers, or only a row of fingers, or only a central finger.

In some embodiments, the tops of the middle two jaws have

chamfers

2024A, 2024B that are inward sloping toward the midline of the two jaws, forming a wedge to more stably press the exposed portion of the wire.

The first conductive element 201 and the second conductive element 202 may have

shoulders

2015 and 2025, respectively, on the outer edges to ensure that they do not move relative to the frame 203 substantially in the first width direction W1 and the second width direction W2, but only in the long axis L1 of the frame 203. For example, for the first conductive member 201, the shoulders 2015 may be disposed at two ends of the first width direction W1, for example, symmetrically disposed at two ends of the first width direction W1. The shoulder 2025 may also be disposed in the same direction as the first width W1 direction, for example, symmetrically with respect to the second conductive member 202. The shoulder 2025 may have a folded back portion to contact the facing surface of the bracket 203 from at least two directions so that the relative position of the second conductive presser and the bracket may be maintained.

The fixing component 204 is disposed on the other side of the conductive pressing member 202 opposite to the conductive holder 201 along the long axis, and may include an inverted nut 2041 and an ejector pin 2042 engaged with the inverted nut. FIG. 5A is an assembled view of the securing assembly, FIG. 5B is an exploded view of the securing assembly, and FIG. 5C is an exploded view of the securing assembly from another angle; as shown in fig. 5A, 5B and 5C, the anti-tip nut 2041 has a body 2041C with a threaded hole 2041D, and two sides of the body are provided with wing-shaped

protrusions

2041A and 2041B, which can be respectively fitted into the

inner grooves

2032A and 2033A, so that the anti-tip nut 2041 can move along the long axis L1 of the bracket 203, and the

surfaces

2041E and 2041F of the wing-shaped protrusions abut against the distal ends of the inner grooves of the bracket when moving to the farthest ends of the inner grooves. The proximal end of the inner groove may be rounded to reduce stress concentrations, and the distal end may be flat to match the shape of the

surfaces

2041E, 2041F of the wing-like projections.

The counter-top nut 2041 abuts the distal end of the inner groove, e.g., 2032C, by counter-movement with the top peg 2042. The top nail 2042 is in threaded fit with the reverse top nut 2041 and can be a flat head screw, a cylindrical head screw, a flat head screw, a set screw and the like. In the embodiment shown in the figures, the locking screw may be a set screw.

The lower portion of the top pin 2042 is a contact portion 2042A for abutting against the first surface 2021 of the second conductive element 202 to define the positions of the first conductive element 201 and the second conductive element 202 in the long axis direction from the long axis direction L1 of the bracket 203.

When assembled, the first conductive presser 201 and the second conductive presser 202 slide from the open end 2034 into the inner space 2034 of the bracket 203 in the long axis direction L1 of the bracket 203, and are positioned on the bracket 203 in the first width direction W1 and the second width direction W2 by the respective shoulders. The inverted top nut 2041 is fitted to the inner groove of the bracket 203 by its wing-like projections and is slidable in the inner groove in the long axis direction of the bracket.

Fig. 8A to 8H show various wiring patterns using the wiring terminal of the present application. In a wiring manner, for example, as shown in fig. 8A, 8B, 8C and 8D, in a wiring manner in which the trunk wire a and the branch wire B are vertically disposed, the exposed portion of the trunk wire a enters between the first surface of the first conductive presser 201 and the bottom plate 2031 of the bracket along the first width direction W1 of the bracket, and the exposed portion of the branch wire B is supported on the supporting claw 2014 of the first conductive presser and pressed below the middle claw 2024 of the second conductive presser 202 along the second width direction W2. The anti-knock nut 2041 is moved away from the second conductive pressing element by rotating the top pin 2042 until it abuts against the distal end of the inner groove, and the contact portion 2042A of the top pin presses the first surface 2021 of the second conductive pressing element 202 by further rotating the top pin 2042, so as to press the first conductive pressing element and the second conductive pressing element against the bottom plate of the bracket 203.

In another wiring pattern, for example, a wiring pattern in which the trunk electric wire a is arranged in parallel with the branch point line B as shown in fig. 8E, 8F, 8G, and 8H, the trunk electric wire a enters between the pressing claw of the first conductive pressing member and the bottom plate of the bracket in the first width direction W1 of the bracket 203 or the first conductive pressing member or the second conductive pressing member, and the branch electric wire B enters between the holding claw of the first conductive pressing member and the claw of the second conductive pressing member in the first width direction W1 of the bracket. In this configuration, the branch wires pass through the passage 2024 between two rows of claws of the second conductive pressing member, and the main wires and the branch wires can be fixed to the two conductive pressing members and the bracket after the first conductive pressing member 201 and the second conductive pressing member 202 are pressed by the top nail 2042.

The first conductive member 201 and the second conductive member 202 may be made of an electrical conductor such as brass, copper, aluminum, stainless steel, or silver. The holder may be made of a conductive material or an insulating material, for example, a conductive material such as stainless steel, cast iron, or the like, or an insulating material such as phenol resin, polypropylene, polyethylene, or the like.

The complementary surfaces of the bracket 203 to the

side plates

2032, 2033 may be completely open or partially closed to define the location of the electrical conductors and prevent the conductors from wobbling. The dimensions of the corresponding first and second conductive pressers in the second width direction may be correspondingly reduced to fit into the narrowed complementary surfaces, which may also save material usage of the first and second conductive pressers, thereby reducing the cost of the overall terminal.

As shown in fig. 1, the insulating housing 100 is disposed outside the first conductive presser 201, the second conductive presser 202, and the bracket 203, wherein the bracket 203 is placed in the recess 1010 of the base 101. The recess 1010, as shown in fig. 10, may be defined by four upright wall panels, wherein a pair of

wall panels

1011, 1012 in a first width direction W1 of the bracket are provided with

arcuate notches

1011A, 1012A that can support insulated sections of trunk wires, and a pair of

wall panels

1013, 1014 in a second width direction of the bracket may have

positioning ribs

1013A and 1014A, respectively, that can ensure that the bracket is positioned at a particular location on the base, thereby facilitating the attachment of the two. For example, the base may be fixed to the bracket 203 by, for example, screwing, and the base and the bracket may be provided with screw holes, respectively, and fixed to each other by screws 205.

The cover 102 may cooperate with the base 101 to form electrical insulation for the wire connection securing structure 200. The upper cover includes a top panel 1025 and four

side walls

1021, 1022, 1023, 1024 extending upright from the top panel. The opposing sidewalls 1021 and 1023 in the first width direction are provided with a pair of notches, wherein the notch 1021A in the sidewall 1021 is about three times the diameter of the insulated wire, and the notch 1023A in the sidewall 1023 is about 1.5 times the diameter of the insulated wire. The

side walls

1022 and 1024 in the second width direction also have notches, wherein the notches 1022A on the side wall 1022 are about three times the diameter of the insulated wire and the notches 1024A on the side wall 1024 are also about three times the diameter of the insulated wire.

The upper cover and the base can be closed, after closing, the notches on the side walls form openings, for example, an oblong opening, namely a first oblong opening, and a circular opening are formed on the side wall in the first width direction, and two truncated oblong openings, namely a first truncated oblong opening and a second truncated oblong opening, are formed on the side wall in the second width direction.

In the aforementioned configuration in which the first trunk wire a and the branch wire B are vertically communicated, the trunk wire a includes, for example, a conductor exposed section and sections with insulating coatings on both sides of the exposed section, the trunk wire a enters between the first conductive pressing member and the support from the first width direction W1, so that the conductor exposed section is in mechanical and electrical contact with the pressing claw of the first conductive pressing member, and the sections of the insulating coatings of the trunk wire a protrude from the first oblong opening lower half and the circular opening in the first width direction, respectively. The branch wire B generally has a bare portion at one end and the other portion is covered with an insulating layer. The bare portion of the branch electric wire B extends into the upper half portion of the first or second truncated oblong opening in the second width direction W2 or in the direction opposite to the second width direction W2.

Alternatively, in another vertical through configuration of the trunk wire a and the branch wire B, the trunk wire a includes, for example, a conductor exposed section and sections with insulating coatings on both sides of the exposed section, the trunk wire a enters between the first conductive pressing member and the second conductive pressing member from the second width direction, so that the conductor exposed section is in mechanical and electrical contact with the claw of the first conductive pressing member and the claw of the second conductive pressing member, and the sections of the insulating coatings of the trunk wire a protrude from the upper half portions of the first and second truncated oblong openings in the second width direction, respectively. The exposed part of the branch wire B can extend into the lower half part of the first long circular opening along the first width direction or enter the circular opening along the opposite direction of the first width direction, and then extend into the space between the first conductive pressing piece and the support to be in mechanical contact and electrical contact with the pressing claw of the first conductive pressing piece.

Alternatively, in the configuration of parallel communication between the trunk electric wire a and the branch electric wire B, the trunk electric wire a includes, for example, a conductor exposed section and sections with insulating coatings on both sides of the exposed section, the trunk electric wire a enters between the first conductive pressing member and the bracket from the first width direction, so that the conductor exposed section is in mechanical and electrical contact with the pressing claw of the first conductive pressing member, and the sections of the insulating coatings of the trunk electric wire are respectively extended from the lower half of the first oblong opening and the circular opening in the first width direction. The branch electric wire B generally has a bare portion at one end, and the other portion is covered with an insulating layer. The exposed portion of the branch wire B extends in the first width direction into the upper half of the first oblong opening and further into between the first conductive presser and the second conductive presser.

In this way, the multi-directional wiring of the connection terminal in the present application, that is, the plural arrangements of the main electric wires a in the first width direction W1 or the second width direction W2 can be realized.

In some embodiments, the base 101 may be designed to have a square or circular cross-section, such that the first width direction W1 and the second width direction W2 are uniform in size. The user can change the angle that sets up of binding post on the different positions of batch meter wantonly to the adaptation is different to use, for example, in the position of inserting trunk electric wire, can make first width direction for being unanimous with the vertical direction of wall batch meter, and in the position of output branch electric wire, can make second width direction for being unanimous with the horizontal direction of wall batch meter.

The upper cover and the base can be combined into a whole in a clamping mode, or in a plugging mode, or in a threaded connection mode, or in a combination of two or three modes, for example, short columns 1026 can be arranged at four corners of the upper cover, holes 1015 with smooth parts at least at the upper sections are arranged at four corners of the base, and the short columns and the smooth parts are determined to be in tight fit, so that the upper cover and the base can be fixed. It is also possible to provide at least one of the studs with a through-going hole and to provide the lower section of the corresponding hole as a threaded portion, the upper cover and the base being fixed by means of a screw which passes through the through-going hole of the stud and can cooperate with the threaded portion.

To further enhance the contact between the top pin 2042 and the second conductive compression element, and to prevent the top pin from slipping off the surface of the second conductive compression element, a dimple may be provided on the first surface 2021 of the second conductive compression element and the corresponding top pin to enhance the engagement of the top pin with the second conductive compression element.

Figures 12A to 12D illustrate the assembly sequence of the electrical terminals in the exemplary embodiment of the present application. As shown in fig. 12A to 12D, the connection terminal in the foregoing embodiment of the present application is generally assembled by first fixing the bracket 203 to the base 101, for example, by a screw 205, as shown in fig. 12A and 12B; then the first conductive pressing element 201 and the second conductive pressing element 202 are inserted into the bracket in sequence, as shown in fig. 12C; then, the back nut 2041 is put in, and the top pin 2042 is screwed into the back nut 2041 to form the fixing member 204. And then the upper cover 102 is sleeved to form the complete terminal.

A typical trunk wire is about 8mm in diameter, a metal core is 6mm in diameter, a typical branch wire is about 7mm in diameter, and a metal core is 5mm in diameter. Therefore, the pressing claw and the holding claw of the first conductive pressing member 210, and the claw of the second conductive pressing member may be sized according to the size of the metal core. For example, the pitch of the two rows of claws of the second conductive presser member may be set slightly larger than the diameter of the metal core of the branch electric wire. Alternatively, the pitch of the outer surface of the middle claw may be set slightly larger than the diameter of the metal core of the branch electric wire.

In some embodiments, as shown in fig. 13, the holding claw 2014 of the first conductive presser and the claw 2024 of the second conductive presser may be arranged alternately in the first width direction W1. For example, the middle two jaws may be sized such that they extend into the space between the opposing two drag jaws. As shown in fig. 6A and 6B, in some embodiments, a wire support 2016 is disposed between the middle two support jaws to support the exposed portion of the wire so that it is not susceptible to swinging about the longitudinal axis L1. In some embodiments, raised wires are provided on the wire mount 2016 to increase the radial pressure on the inserted wire, thereby making the wire less likely to come off.

In some embodiments, as shown in fig. 14, the securing assembly 204 may include a pressure plate 2043 that rotatably engages the open end 2034 of the holder. For example, one or adjacent sides of the pressure plate 2043 may be hingedly connected to the side of the frame on one side of the open end, while the opposite or adjacent sides may have snap-fit features that snap into the interior channel of the frame. So that a closed structure can be formed at the top end of the bracket; threaded holes 2043A may be provided in the pressure plate 2043 so that the studs 2044 may engage the threaded holes 2043 so that the threaded portions of the studs may extend into the interior space of the bracket to engage the first surface of the second conductive pressing member to define the positions of the first and second conductive pressing members in the direction of the major axis L1.
