Description

【Technical field】
[0001]
The present invention relates to terminal boards for interconnecting electrical lines, especially telephone lines or computer lines.
[Background Art]
[0002]
Patent Literature 1, Patent Literature 2, Patent Literature 3, and Patent Literature 4 describe a terminal plate.
[0003]
Generally, the terminal plates are often mounted on metal fixed rails that form a grounded support frame. The terminal boards are mounted such that their sides touch each other or are very close.
[0004]
However, prior art terminal strips have a considerable thickness. As a result, the number of terminal boards that can be mounted on the metal fixed race having a predetermined length is reduced. A major disadvantage of such current terminal strips is that the terminal strips are dimensioned such that the capacity of the fixed rail portions forming the support frame is limited.
[0005]
Further, these terminal plates are composed of two rows of conductive elements called "press-contact terminals" arranged in parallel with each other. Each of these has a press-contact end configured to receive an external wire and is aligned in two rows facing the body of the terminal plate. These press contact terminals are connected to wires or jumper wires. Because of this parallel row, the input and output arrays of terminal boards are located on the same vertical side of the terminal board. This causes high density connections and interlacing of the wires with the bundle of wires.
[0006]
Another disadvantage of the prior art terminal strips is that access to the terminal strip located in the center of the other terminal strip to change the connection is such that such terminal strips are arranged in groups along metal fixing rails and It is difficult if the terminal board is once connected.
[0007]
Patent document 5 discloses in particular a connecting device for a telecommunications line, the connecting devices being arranged side by side in parallel with each other, each consisting of a conductive element divided at one end for accommodating an external line, The elements are held axially between the two mounting parts of the insulating casing and constitute two straight lines, rows or arrays arranged in opposing relation within said casing. The split end of the plug is arranged in the direction of the longitudinal side of one part of the casing, opposite the bare mounting side of said part of the casing. The longitudinal side of the casing is, on the one hand, opposite to the slot at the end, a drive or guide slot which is provided transversely to said longitudinal side and is open on two surfaces adjacent to said longitudinal side. And, on the other hand, an access slot passing longitudinally on the same longitudinal side of the casing between two straight lines at the split end of the conductive element.
[0008]
However, one of the disadvantages of this type of connection device is the thickness due to the two rows of conductive elements. Another disadvantage is that there is no means to accommodate the connection lines. Yet another disadvantage of the prior art connection devices is that the input array is not separated from the output array.

[0016]
The present invention will be more fully understood from the various advantages and features which become apparent by reference to the following description, non-limiting embodiments, and the accompanying schematic drawings.
BEST MODE FOR CARRYING OUT THE INVENTION
[0017]
The multi-contact interconnection terminal plate 1 includes two generally rectangular side surfaces 2, 3, a left side portion 4, a right side portion 6, an upper vertical side portion 7, and a lower vertical side portion 8. Have.
[0018]
The upper vertical side portion 7 has a row of upper metal pressure contact terminals 9. The lower vertical side portion 8 has a row of lower metal pressure contact terminals 11. These press contact terminals 9 and 11 are located in the same plane P. This plane P is parallel to the two sides 2,3. The upper and lower insulation displacement terminals 9, 11 each include a slot 12 for inserting an external wire. These insertion slots 12 always face press-fit slots 13 formed in the main body of the terminal plate. The press-fit slot 13 is formed on one side surface 3 of the terminal plate. The press-fit slot 13 extends upward in the case corresponding to the upper press-connecting terminal 9, and extends downward in the case corresponding to the lower press-contact terminal 11.
[0019]
The upper terminal 9 is physically separated from the lower terminal 11. The upper terminals 9 each have a flexible knob 14 located at the end opposite the press-contact end. The lower terminals 11 each have a rigid or fixed portion 16 located at the end opposite to the press-contact end. The flexible knob 14 and the fixing portion 16 are in contact with each other to form a contact point and a breaking point 17.
[0020]
The rest position of the flexible knob 14 of the upper insulation displacement terminal 9 is shifted from the plane P defined by the upper 9 and lower 11 terminals. The fixing portion 16 of the lower press contact terminal 11 is also shifted with respect to the plane P defined by the upper and lower terminals 9, 11. This means that the cutoff point is shifted with respect to the same plane P.
[0021]
An upper hole 18 for inserting a plug 19 is provided for each press contact terminal 9 in the terminal plate 1. This plug (see FIGS. 7B and 7C for details) is inserted into the terminal plate (in the direction of arrow T) up to a breaking point 17 between the flexible knob 14 of the upper pressure terminal 9 and the fixing part 16 of the lower pressure terminal 11. ) Can be inserted. FIG. 7A shows two possible positions of the flexible knob 14, ie, the position of the protrusion, shown along the plane P, when the plug 19 was inserted, the flexible knob 14 was forced away from its rest position. The position is specified. The plug 19 is inserted by moving parallel to the longitudinal axis of the upper and lower insulation displacement terminals 9, 11 (along the arrow T) and thus also parallel to the plane P.
[0022]
Two types of test plugs 19 can be used. The insulation test plug can be used to cut off the connection between the upper terminal 9 and the lower terminal 11. Using the continuity test plug, the state and characteristics of the conductive wire connected to the terminal plate can be measured and tested.
[0023]
In order to connect the input array, a vertical channel 21 is provided below the press-fitting slot 13 and this channel is adapted to draw in the external line by inserting an external line. Channel 21 borders rib 22 at the top. The channel is bordered by a comb 23 at its lower part. As shown in the figure, when there are 16 lower press-connecting terminals 11, 16 wirings pass through the ring 24 and “comb” by 16 gaps between the teeth defining the comb 23. be able to. By grasping the wiring more reliably, it is possible to improve the mechanical strength, better conduction and connection of the lower press contact terminal 11. Each wiring is connected directly to each press-fit slot 13.
[0024]
To connect the output array, the same side 3 includes a series of lead-in channels 26. Each lead-in channel 26 extends from the lateral part 4 to the press-fit slot 13 for the upper press-fit terminal 9. If sixteen upper insulation displacement terminals 9 are provided (as shown), sixteen lead-in channels 26 can be arranged in the vertical side 8. Preferably, the lead-in channel 26 forms a substantially curvilinear curve to prevent sharp bends in the wiring passing through the lead-in channel 26. Since the connection lines can be actually arranged by the lead-in channel 26, a space can be secured.
[0025]
A completely flat plate 27 is provided on the other side 2. When the interconnect terminal board is inserted into the rail forming support frame 28, one of the terminal boards 27 partitions the lead-in channel 26, etc. of that terminal board to the end of the rail. At the end, either a component that also forms a label holder 29 or a mere plate is provided for partitioning the exposed lead-in channel 26 of the terminal plate.
[0026]
The cable with insulation and its outer line 30 are advantageously located on the bottom of the U-shaped rail forming the support frame 28.
[0027]
In order to fix the interconnection terminal plate to a rail forming a support frame 28 having a U-shape with two upwardly extending side arms 31, 32, two insertion and fixing means are respectively provided on the terminal plate. It is provided on both sides. These means are in the form of a three-sided frame (jamb) 33 attached at the central part to each lateral part, namely the left lateral part 4 and the right lateral part 6. Thus, these two triangular frames 33 define four slots 34 into which the two side arms 31, 32 of the rail 28 can be inserted.
[0028]
The triangular frame 33 includes a fastener 36 that projects into the slot 34 and engages an opening 37 in the side arm 31, 32 of the rail 28. Two of the slots 34 extend upwardly along the lateral sides of the terminal plate and open to the upper longitudinal side 7, while the other two slots 34 It extends downward along the horizontal side and opens toward the lower vertical side 8. The two triangular frames 33 on each side of the terminal plate each also include two gripping hooks 38 for individually moving the triangular frames 33 on that side to expand the slots 34, and the rails forming the support frame 28. The two side arms 31, 32 can be inserted or removed after the fastener 36 is disengaged.
[0029]
For this reason, the operator first mounts the terminal plate on the rail forming the support frame 28, and connects the wiring to the terminal plate by inserting the outer wire into the lower press contact terminal 11 with the lower vertical side 8 facing upward. . Next, the operator removes the terminal plate, turns it over, and re-fits it on the rail forming the support frame 28, thereby inserting the outer wire into the upper press contact terminal 9 and turning the upper vertical side portion 7 upward. be able to.
[0030]
As can be seen in detail in FIGS. 5 and 8, the rail having a U-shaped cross section forming the support frame 28 has an asymmetric shape in which one side arm 31 is longer than the other side arm 32. Good. This means that on one side of the terminal plate the slot 34 of the terminal plate may be deeper than the slot 34 on the other side of the terminal plate. Having the slots having different depths increases the mechanical stability of the terminal plate 1.
[0031]
For example, when the 32 terminal boards are mounted on the rail 28 having a predetermined length, other means are provided for fixing the terminal boards to each other. These means are in the form of dovetail mortises 39 (FIG. 3) protruding a few millimeters on the side 3 with the retraction channel 26 provided thereon. These mortises 39 engage with groove-like mortises 41 running from the side having the side face 2 with the flat plate 27 to the entire height of the terminal plate. This joins the terminal plates together, arranges the maximum number of terminal plates on the rails 28, efficiently partitions the lead-in channel 26 with the terminal plate flat plates 27 aligned in a straight line, and provides a good mutual machine of terminal plates. A strong binding force can be provided.
[0032]
To improve the selection of the connection, a drain collector is provided in the form of a metal knob 42 (FIG. 6) which leans on the insulating side plate 43 of the terminal plate body. As a result, the drain wires can be collected and grounded via the support frame 28.
[0033]
A plug 44 of a jumper (FIG. 8) is also provided for insertion into the upper insulation displacement terminal 9 to allow cross-connection in a telephone, computer or other wiring board.
[0034]
A label holder 46 is provided on the upper vertical side 7 so that various terminal boards can be recognized among the terminal boards. When all the terminal boards are arranged side by side close to each other, the label holder 46 is slid on an individual label for each terminal board, or is slid on a single long label.
[0035]
The invention is not limited to the described and illustrated embodiments. Many modifications may be made without departing from the scope of the appended claims.
