Description

Staggered socket set

The present invention is a divisional re-application of the following divisional applications which have issued an authorization notice:

divisional application No. 201811413635.9

Parent application No. 201380031344.2 (PCT/IB2014/067400)

This division is made based on the existence of a "singleness" defect as indicated by the examiner.

Technical Field

The invention relates to various socket forms for smooth cable pipelines in buildings.

Background

Whether a cable pipeline in a building is unblocked or not is influenced by two important parameters: the bending radius of the pipeline during turning and turning; second, the accumulated turning angle on the pipeline.

One PCT application, PCT/CN2007/001172, and its cognate british patent, GB 2450851a, and chinese patent, CN 101427433a, disclose a method of clearing a cable duct. The invention solves the problem that the bending radius of a cable pipeline in a building reaches more than 10 times of the pipe diameter under the limitation of harsh construction conditions. Meanwhile, the 'pseudo-three-dimensional bent pipe' is rotated, so that the accumulated turning angle of the cable pipeline can be reduced to a certain extent.

Figure 1 shows a view of a standard "pseudo-solid elbow" in which the pipe has a bend radius R more than ten times the pipe diameter D.

Fig. 2 is a schematic view of the pseudo-solid bent pipe after being flattened. The pseudo-solid elbow is represented by a thick solid line, a straight line f is an intersection line of two planes to which an OP section and an OQ section of the pseudo-solid elbow belong, a ray m and a ray n are respectively perpendicular to the intersection line f and tangent to circles to which two plane arc pipe sections belong in the two planes, and the two planes to which the pseudo-solid elbow belongs are mutually perpendicular. Here, the cumulative turning angle of the pseudo-solid bent pipe POQ is the sum of two 90 ° angles, i.e., 180 °.

The 'rotation' of the pseudo-solid bent pipe can be decomposed into two steps: rotating along the direction of the ray n by taking the ray m as a rotating shaft; the ray n is taken as a rotating shaft and rotates along the direction of the ray m. The two rotations are not divided in sequence.

Fig. 3 is a plan view of the pseudo-solid elbow after it has been "rotated" as described above and flattened along a new intersection line g. It is noted that two intersection lines f are shown, which reflect the actual positions of the intersection lines f in different planes, the intersection line f perpendicularly intersecting the ray m being in the plane of the tube section OP and the intersection line f perpendicularly intersecting the ray n being in the plane of the tube section OQ. By "spinning", the pipe section PPm and the pipe section QQn become "redundant" parts.

In fig. 3, Ψ m and Ψ n are the turning angles of the planar elbow sections OPm and OQn after the rotation of the pseudo-stereo elbow, respectively, so that the cumulative turning angle Ψ of the effective part after the rotation of the pseudo-stereo elbow is Ψ m + Ψ n. Since Ψ m and Ψ n are both smaller than 90 °, Ψ < 180 °.

However, the reduction in cumulative turn angle that can be achieved by "rotation" is limited by practical considerations, since the maximum achievable "rotation" is limited by the vertical deflection limiting distance allowed for the building body.

This can be clearly seen in fig. 4.

In the figure, the straight line c is parallel to the intersection line f and is separated from the two planes before rotation by a and b, respectively, which are the vertical deflection limit distances allowed by the building body.

To significantly reduce the cumulative turn angle of a cable line, each turn angle on a line must be reviewed.

Disclosure of Invention

The invention reduces the accumulated turning angle of the pipeline by greatly reducing the local turning angle of the outlets at the two ends of the pipeline.

The method claimed by the invention is used for reducing the accumulated turning angle of a cable pipeline connected between sockets on two wall surfaces in a building, the middle section of the cable pipeline is laid on the ground, and the junction of the two wall surfaces and the ground respectively comprises a pseudo-three-dimensional bent pipe, and is characterized in that when the socket is installed on the wall surface, an included angle smaller than 90 degrees is formed between the surface, butted with the cable pipeline, of the socket and the vertical line of the ground.

Fig. 5 shows several examples of typical in-building plumbing arrangements. The pipeline path design adopts the method disclosed in the aforementioned PCT/CN2012/001172 and the patent document of the same family. In the figure, the

sockets

101, 102 and 103 are located on one wall, and the socket 100 is located on the other wall; g1 and g2 are the intersection lines of the two wall surfaces and the ground; w₁、W₂And W₃The horizontal spacing between the

receptacles

101, 102 and 103, respectively, and the receptacle 100. The conduit between the

sockets

100 and 101 comprises four right-angled bends with an accumulated turn angle of 360 °; the cumulative turn angle of the tubing between the

sockets

100 and 102 is also 360 °; the situation between the

sockets

100 and 103 is different, because the horizontal distance between the

sockets

100 and 103 exceeds 4 times of the turning radius R, the section of the straight pipe on the ground is not perpendicular to the wall surface any more, so that the turning angle omega of the two sections of the bent pipe on the ground is enabled to be equal to the turning angle R₃₁And Ω₃₂Both less than 90 °; thus, the cumulative turn radius of this pipe is: 180 degrees + omega₃₁+Ω₃₂Less than 360 deg. Extreme conditionsUnder the condition of omega₃₁And Ω₃₂As the angle approaches 0 °, the cumulative turning angle approaches 180 °.

The minimum cumulative turning angle achievable for a conduit between two opposing wall sockets is related to the horizontal separation W of the two sockets as shown in fig. 6. Here, the possible fine spacing between the socket-to-tubing interface and the socket center is ignored; meanwhile, the bending radius of all bent pipes is assumed to be R, and the pseudo-three-dimensional bent pipe is not rotated. When W is less than or equal to 4R, the accumulated turning angle is always 360 degrees; when W > 4R, the cumulative turning angle starts to decrease and gradually approaches the limit value of 180 ° as W increases.

Increasing W in order to reduce the cumulative turning angle is a method that can be fully utilized, but it is often impractical to pursue such a method.

In fig. 7, the angle of rotation Ω of the elbow pipe with the bending radius R of the connection socket 100₀Is 90. If the angle of the turn is to be reduced, the angle at which the socket 100 intersects the elbow must be adjusted.

Fig. 8 shows a major improvement of the invention, i.e. the plane where the socket 100 meets the elbow is no longer horizontal, but forms an angle Ω of less than 90 ° with the vertical m of the ground₁(ii) a Angle omega₁Preferably between 30 ° and 60 °.

Notably, the height of the socket from the ground is typically 30cm to 35 cm; if R ≈ 30cm is selected, the elbow of the connection socket 100 in FIG. 7 is exactly one 90. Whereas in fig. 8, since the turning angle is reduced to Ω smaller than 90 °₁A small length of straight tube may need to be added between the socket 100 and the elbow.

Because the original 90-degree bent pipe is changed into a small-section bent pipe and a small-section straight pipe, under the condition that the vertical position of the socket is not changed, the horizontal position of the socket must be translated by a small distance mu; this distance can be estimated: when omega is higher than₁At 45 °, μ ≈ (√ 2-1) R ≈ 0.4R.

Figure 9 shows a piping diagram using the socket tilt solution. Comparing with fig. 5, it can be seen that the cumulative turning angles of the three pipes are greatly reduced.

When omega is higher than₁At 45 deg., the minimum cumulative turning angle that can be achieved for a line between two opposing wall sockets is related to the horizontal separation W of the two sockets as shown in fig. 10. When W is less than or equal to 4R +2 mu and is approximately equal to 4.8R, the accumulated turning angle is 270 degrees all the time; when W > 4R +2 μ ≈ 4.8R, the cumulative turning angle starts to decrease, and gradually approaches this limit value of 90 ° as W increases.

Ω₁Taking different values, the following comparative data (table 1) can be obtained:

Detailed description of the preferred embodiments

The basic principle of the invention is that an inclination angle is formed between a surface of a socket of a wall surface, which is connected with a pipeline, and a vertical line; this can be either a conventional square socket or a two-position rectangular socket angled arrangement or a new socket geometry can be used.

Figure 8 shows a basic embodiment prototype of the invention. In contrast to the prior art of fig. 7, the socket 100 is tilted so that the original turning angle is Ω₀The bent pipe is changed into a bent angle omega₁The elbow pipe of (2).

Fig. 9 shows the layout of the pipeline after the inclination scheme is adopted. The cumulative turn angles of the conduits from the receptacle 100 to the

receptacles

101, 102, 103 are all substantially reduced compared to figure 5. When each socket adopts a 45-degree inclination angle, the accumulated turning angle of each pipeline can be reduced by 90 degrees. The smoothness of the pipeline is greatly improved.

As can be seen from FIG. 10 and Table 1 in the foregoing, with Ω₁The accumulated turning angle of the pipeline is reduced by two times, namely 2 omega₁(ii) a But the straight tube connecting the elbow and the socket becomes correspondingly longer and flatter. Figure 11 is an embodiment employing a 45 deg. tilt angle. The five adjacent sockets 100 are arranged in two rows after being inclinedThe shape of the letter "M". Two of the sockets are connected by a bend 88, referred to herein as a "bypass bend".

Fig. 12 shows another embodiment. Omega₁Approximately equal to 30 degrees, and five sockets are horizontally arranged, staggered in sequence and partially overlapped together. There are two bypass elbows 88 connected to a pair of sockets that are not adjacent to each other.

It should be noted that Ω₁30 means Ω₂Approximately equal to 60 degrees. That is, the angle of the elbow connecting the lower right side is 60 °.

In combination with the advantages and disadvantages of all aspects, the 45 degrees which are symmetrical left and right are considered to be a preferable scheme which has both sides and is convenient to implement.

Fig. 13 is an embodiment of a dual bit socket. There is still a bypass elbow 88 angled at 90 degrees to connect a pair of left and right non-adjacent sockets.

The purpose of the bypass elbows provided in the several embodiments above is to facilitate cable passage between the sockets. Because the space of the conventional square socket is limited; cables, especially those that are relatively hard and thick, are almost impossible to run smoothly. There is no excess space available to reserve some cables in the socket for future use.

Fig. 14 shows a situation where the cables 87 in the conventional jack are crowded at corner corners. In fact, these "transit" cables 87 inevitably interfere with the smooth installation of the power or information outlets.

Although, it is also possible to supplement the socket with a similar bypass elbow, such as the bypass elbow 89 in fig. 15; however, the turn angle of the bypass elbow is 180 ° here, whereas the turn angle of the bypass elbow 88 in the previous embodiment is only 90 °, which is clearly out of order.

In view of the foregoing analysis of the problems with existing sockets, we propose a new socket design.

The internal geometry of the new socket is composed of a square space and two isosceles triangle spaces. The whole appearance is seen, and the new socket is a hexagon with two parallel sides. The waists of both triangles are sides of a hexagon. As shown in fig. 16, the middle square region 1000 of the new jack on the right side has a space size substantially equal to that of the conventional jack 100 on the left side; the new jack has a triangular area above and below, respectively, called the wire passing areas (1001 and 1002).

FIG. 17 is a detail of an embodiment of the tubing after the new receptacle is used. Due to the triangular wire passing area, the novel sockets do not need to be inclined to realize the reduction of the turning angle, and two inclined edges below the sockets just meet the requirement.

At the same time, the turn angle of the bypass elbow 88 connecting these triangular wire passing regions is also much less than 180 °. If the triangle is a regular triangle, then Ω₁The bypass bend 88 has a bend angle of 90 °, 45 °.

The existence of the triangular wire passing area provides great convenience for the 'passing' of the cable. The turning angle of the cable is also greatly reduced. Especially for hard and thick cables which are difficult to turn, it is much easier to achieve a 90 ° turn angle than a 180 ° turn angle in a small socket interior space.

Moreover, the presence of the triangular wire passing area and the bypass elbow prevents the socket central space 1000 from being occupied. Similarly, when the "cross-border" cable needs to be adjusted or replaced, the power socket or the information socket which is originally installed may not need to be detached due to the existence of the triangular wire passing area and the bypass bent pipe.
