Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information network socket having a metal housing lower part, a metal housing upper part, and a circuit board incorporated between the housing lower part and the housing upper part.

[0002]

BACKGROUND OF THE INVENTION Such sockets are mounted on a wall. The wall here may be either the building wall or the outer wall of the cable duct. Multi-strand information cables can be integrated inside walls or cable ducts or laid out outside the walls (surface wiring). Assembling the socket requires electrically connecting the stripped wire to the wire terminal and also electrically connecting the shield of the information cable to the frame terminal of the circuit board. In preparation, the insulation outside the end of the information cable is first removed to expose the shield. Then remove part of the shield so that each strand can be unrolled. In a conventional socket, the exposed shield is directly connected to the ground plane of the circuit board. Due to the location of the connection points and the paths that lead each conductor to the wire terminals, at least the circuit board must be held during part of the work of the electrical connection. The socket can only be mounted on the wall after making the electrical connection and assembling the metal box. Usually, a plastic cap is finally placed over the metal parts of the socket.
It is difficult to align the information cables neatly even when assembled quickly. Furthermore, depending on the direction in which the information cable is guided into the socket, the information cable is often bent very tightly several times inside the plastic cap. Assembly is particularly inconvenient when the information cable needs to be extended beyond and connected to another information cable.

[0003]

SUMMARY OF THE INVENTION It is an object of the invention to provide a general socket which is quick, orderly and easily assembled and which ensures an acceptable situation for signal transmission.

[0004]

The above object is achieved by the device of claim 1.

The end portion having the exposed shield is electrically connected by being clamped to the support base portion in the lower part of the housing. At this time, the lower part of the housing can be attached to the wall. First, since the end portion is fixed to the correct position on the lower part of the housing, the information cable can be laid flat in an orderly manner without being affected by the subsequent treatment. Each of the strands unrolled after the restraint can be bent upwards without any problems, they pass through the notches in the circuit board when it is mounted in the lower part of the housing. The ends of each strand can be connected to the wire terminal with both hands. In this case, the length of each uncoated strand is very short, which minimizes transmission loss and distortion.
Finally, the metal housing top and then the plastic cap is mounted as usual.

According to the device of claim 2, the information cable can be laid more gently, which is particularly useful when the information cable emerges from a wall.

According to the device of claim 3, two information cables coming from one main direction can be incorporated without any problem.

According to the fourth aspect of the invention, the two information cables coming from the two opposite main directions can be incorporated without any problem.

According to the apparatus of claim 5 or 6,
The ends of the information cable can be arranged neatly and held down gently.

According to the apparatus of claim 7, the tightening screw can be firmly fixed very conveniently.

According to the apparatus of claim 8, a very short and reliable ground connection can be made.

According to the device of claim 9, two information cables can be connected by a short path.

According to the apparatus of claim 10, the applicable range is widened.

According to the apparatus of the eleventh aspect, reduction of the assembling time is promoted.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG.
A metal housing lower portion 11, a circuit board 12, and a metal housing upper portion 13 are provided. The plastic caps that cover these parts are well known and will not be described in detail here. The circuit board 12 has a multi-layer structure and has two outer conductor surfaces at a frame potential and mutually insulated conductor paths extending between them, the conductor paths each including a wire terminal 14 and a modular socket 15.
And are electrically connected by a known method. Instead of the modular socket 15 described here, another type of information socket connection may be provided.

As shown in FIGS. 2 and 3, the lower part 11 of the housing has a bottom wall 26 and two side walls 21 and 22.
6 has a flat base surface 17 and an opposite bottom upper surface 18,
The two side walls 21 and 22 are located opposite to each other with respect to the plane of symmetry 19. As can be seen from the top view, the housing lower part 11 has a T-shape. The reason is that the part of the wire terminal 14 of the circuit board 12 incorporated therein is slightly wider than the part of the modular socket 15. 2 and 3, the bottom wall 16 extends to the right of the side walls 21 and 22. The reason is that the two holes 23 and 24 used for mounting to a wall (not shown) by mounting screws (not shown) have a standard spacing, which is longer than the length of the lower part of the housing. Because.

A roof-shaped support base 25 is provided at approximately one-quarter of the bottom wall 16, and its upper end 26 extends parallel to the base surface 17 and orthogonal to the plane of symmetry 19. The support base 25 on one side of the plane of symmetry 19 is formed with two trough-shaped support surfaces 27 and 28 whose longitudinal axes coincide with each other and extend parallel to the plane of symmetry 19. ing. The two support surfaces 27 and 28 rise in opposite directions from the bottom top surface 18 at a tilt angle of 30 ° towards a common top end 26. Due to the symmetry, on the other side of the plane of symmetry 19 there are corresponding bearing surfaces 29 and 30. Plane of symmetry 19

A flat intermediate surface 33 with 4 is likewise situated between the support surfaces 28 and 30 which are located opposite to each other with respect to the plane of symmetry 19. A screw (not shown) can be screwed into each of the screw holes 32 and 34, and the screw is used to fix the restraining bracket 35 (shown in FIG. 1) for holding the end of the information cable 36. You can

The position of the information cable 36 is shown schematically in FIG. The end portion peeled off by the shield 37 is held against the support surface 27 by the restraining bracket 35,
The other part of the information cable 36, which is not particularly shown, is formed by a commonly available cable binder, and the cable pedestal 3 protrudes like a hook on the bottom upper surface 18.
It is fixed to 8. Similar cable pedestals 39, 41 and 42 are provided at other positions of the bottom wall 16 so that a total of four information cables can be attached to the housing lower portion 11 by the same method. However, the number of information cables actually connected is at most two, and they can lie in opposite directions. Therefore, as shown by the arrow in FIG.
There is a main direction 43 and a main direction 44 opposite to this,
All of these are parallel to the plane of symmetry 19. in this case,
Information cables (eg 3
6) can be fixed on one side of the plane of symmetry 19 and likewise allows a second information cable (not shown) coming in along the main direction 43 to be on the other side of the plane of symmetry 19, or A second information cable (not shown) coming in along the main direction 44 can likewise be fastened to the other side. The information cable extending to the lower housing 11 along the two main directions 43 and 44 does not have to be bent until it is fixed to the support base 25. However, in practice, the information cable can optionally be bent laterally after being fixed to any of the cable pedestals 38, 39, 41 and 42, and also with a sufficiently large bending radius.

FIG. 2 shows the possibility of another method of providing the information cable. The bottom wall 16 has two regions 45 and 4 of circular contour which can be removed by breaking the joint.
6 are provided. Therefore, a hole can be formed in the bottom wall 16 as needed without using a special tool,
An information cable running through a wall or cable duct through the hole can be guided into the box.

The circuit board 12 must be fixed to the lower housing part 11 above the bottom upper surface 18 with a first gap that secures a necessary clearance for the information cable fixed to the lower housing part 11. . This distance is equal to the end face 4 of the side walls 21 and 22.

Since the wire terminal 14 is provided on the upper surface, when the circuit board 12 is supported at a predetermined insulating position of the housing lower portion 11 already screwed securely to the wall, the respective strands 59 can be connected. After the electrical connection is made, the housing upper portion 13 is attached to the housing lower portion 11 and is fixed by a tightening screw (not particularly shown). At that time, the shaft portion of the screw is screwed into the screw mounting portion 52 of the pin 51, and the head portion of the screw is supported on the supporting surface 63 of the housing upper portion 13. Lower case 11 and upper case 1
When the three are clamped together, the circuit board 12 sandwiched between them is also fixed at the same time, and the web 53 is pushed by the stress. The housing upper portion 13 has notches 64 and 65 through which the plug insertion ports of the modular socket 15 pass. A screw sleeve 66 is provided on the upper surface of the housing upper portion 13, and a tightening screw for attaching a plastic cap (not shown) is engaged with the screw sleeve 66.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made. For example, support surfaces 27 and 2
8 and 29 and 30 may be flat surfaces. In this case, the plane may be inclined like a roof or parallel to the base surface 17.
