(in context, for example " first " in first hole and second hole and " second " are that a kind of label is not meaned different shape and so on.In fact second hole of adapter generally is equivalent to first hole of terminal board).

Term " binding post " is readily appreciated that the professional and technical personnel.This term meaning is a terminal, generally is tiny and is threaded, and is used for connecting lead.Usually, binding post is the part of terminal board.The prior art binding post has pin thread, just has the form of bolt, and nut is twisted thereon with fixing cord to be electrically connected.In the present invention, block (negative thread is arranged, just have the form of nut, but also can have selectively device that for example removes insulated hull or the groove that keeps encapsulant) can be used on this connecing on the binding post.See that term " binding post " (and term " terminal ") comprises also that here a jockey (form that just has nut) and the block with bolt form with negative thread can twist thereon herein from knowing.The binding post (see figure 8) of this form can be contained in the hole of terminal board, follows block as shown in Figure 9 to use together.

The body of adapter of the present invention preferably one by insulating material, the block that is generally plastic material, makes, its first and second surface is flat (but can be fluted to hold encapsulant on it) and be parallel to each other basically.First and second generally have big limit size a 2～10cm, are 3～6cm and little limit size a 1～5cm mostly, are 1.5～2cm mostly.Spacing between first and second surfaces, the thickness of block just, preferably 0.5～3cm mostly is 0.75～1.5cm greatly.If this adapter is the reformation that is used for such as the terminal board of the 9A1 of west electrical equipment company or TII 325 these classes of type, this block preferably is about 2.5 * 4cm, and thickness is 1.0cm.Several such blocks can be placed side by side on several pairs of posts, to and between at a distance of about 2.5cm, about 2.2cm apart between every internal binding post.

Body can be made special shape, two or more can nestling up basically abreast placed, its first surface and second surface can be regarded rectangle as, remove one or more angles to allow adjacent layout, consider a hard branch wiring will holding to come out from second hole.Therefore body can have first side and second side that stretches between first surface and second surface, divides wiring to set and stretches from a perforate of second side.Thereby the shape of first side preferably adds one with second side basically what stretch out therefrom is straight branch wiring shape altogether identical (at least from body plane figure) basically.

Second hole is preferably straight, may be hard because divide wiring, so just be difficult to insert in the curved hole, and when hope divides wiring preferably relevantly to be contained in the hole, be like this particularly.The preferably microscler and cross section in hole is (though a fluting can be for example contained in the hole) of sealing.Thereby this is because such hole can be located with respect to first hole minute wiring better with respect to binding post, more suitably to contact with block.We recommend second hole to have noncircular cross section, like this, divide heart yearn in the wiring at a noncircular cross section multicore, with respect to first hole thereby the orientation that is maintained fixed with respect to binding post.

That first hole is preferably sealed, especially wish it is circular cross-section.Can there be less diameter (being preferably substantially equal to the binding post diameter) in each first hole on first surface, bigger diameter is arranged on second surface.This is preferably substantially equal to block than major diameter and includes that part of diameter in the hole in when it is enclosed within on the binding post, so the hole is with the level, from the degree of depth of major diameter to the transition portion of minor diameter restriction block socketing terminal, thereby preventing to damage lies in following branch wiring.But other device can also be used for limiting the stroke of block on binding post, for example, and a top that blind end is reliably gone up binding post of block.

Block preferably includes the device of incision insulated hull, shear blade mouth for example, therefore, when block is down stubborn along binding post, cutting edge divides the insulated hull of wiring below just incision lies in, and wishes that cutting edge is cut to wear insulation but can not be more further deeply, otherwise can damage the heart yearn of branch wiring.Therefore best device is exactly the device of above-mentioned restriction traverse.Like this, the diameter transition place that second hole can be mentioned in the above inserts in first hole, and like this, the heart yearn of the branch wiring in second hole mainly is placed in the part than minor diameter, and the insulated hull that will cut is positioned at larger-diameter part, thereby the cutting edge of the incision insulated hull of block can get at.

Binding post and block are preferably with screw thread, and like this, block just can be screwed on the binding post simply.The device of incision insulated hull is an annular cutting edge preferably, a heart yearn of its only topped minute wiring, rather than two heart yearns are all topped.Therefore second hole can be between two binding posts athwart, and the one side that makes branch wiring within it is near a binding post, and relative one side is near another binding post.When block is screwed on the binding post, the incision of the cutting edge of a block divides half of wiring and the cutting edge incision of another block divides second half of wiring, thereby the cutting edge of block just touches heart yearn, and we recommend, and does not need block is thrown off the contact that just can disconnect with heart yearn fully.This just allows by unscrewing a block from a pairs of posts selectively and comes circuit of getting back to central control room or going to the user from terminal board of independent test.

A kind of encapsulant can be used to seal binding post, block and/or divides wiring that further environmental sealing is provided, though can be embedded in the interior desirability that has reduced this encapsulant of body owing to flimsy surface and formed joint in the present invention.

A kind of encapsulant of the best contains a kind of gelinite, for example, and based on the gelinite of polyurethane or organosilicon.As an example, can mention a kind of material, this material by the polyurethane precursor material of plasticization being placed on suitable capacity mineral oil, vegetable oil or plasticizer or above-mentioned two or more mixture in condense and make.By being plastified together with the agent of nonactive organosilicon increment, active organosilicon also can make a kind of suitable material.This material can comprise the additive such as dehumidizer (for example chlorobenzoyl chloride), antioxidant, pigment and bactericide.This material preferably electric insulation and hydrolysis do not take place.

We recommend, and the sealing material has that measure under 21 ℃ temperature by ASTM D217-68, a 100～350(10 ^-1Mm) awl value of penetrating, 150～350 is better, is more preferably 200～300(10 ^-1Mm).The awl value of penetrating is to measure on undisturbed sample with 1: 1 ratio conehead of a standard (conehead weighs 102.5 grams, spool weigh 47.5 restrain), and the value of penetrating measured after 5 seconds.This material preferably have one by ASTM D638-80 21 ℃ of measurements, be at least 200% limit elongation, be 500% better at least, be more preferably at least 750%.In the measurement of elongation, mould with a model 4 is cut sample, elongation is to measure under the speed that 50cm/ divides, we find to use this material energy pairs of posts, block and/or branch wiring etc. that fabulous sealing is provided, particularly to remain on pressured state following time around above-mentioned parts be so to these materials, checks but this material can take off from these parts neatly and repair.This encapsulant can be placed in the block or in the groove of body.

Terminal board of the present invention can contain any above-mentioned relevant characteristics relevant with adapter, in general, terminal board contain one have at least two pairs, best 2～25 pairs, better be 2～10 pairs, be more preferably the body seat of 5 or 6 pairs of posts.Every pairs of posts can have a hole that can hold a branch wiring as described above.Terminal board can have the termination that the device such as a groove is used for holding a multicore cable, and can be provided with the device that is used for eliminating cable stress.It can be contained in the cover.

Figure 10～13 illustrate can be regulated to adapt to the adapter of different binding post spacings.

Fig. 1 illustrates a prior art terminal board 1, and it contains a body seat 2 that has 5 pairs of posts 3.A branch wiring 4 has been shown on the figure to be connected on the binding post by means of packing ring 5 and nut 6.

Adapter 7 of the present invention shown in Fig. 2 is in the situation on the binding post 3 of preparing to be placed to a prior art terminal plate body seat 2.Adapter 7 contains a body 8 and block 9.Body 8 has two first holes 10 to be stretched over second surface 12 from the first surface of placing near terminal board 11.First hole has bigger size 13 at second surface 12 places, and 11 places then have less size 14 at first surface.Large-size 13 is used to put a part 15 of block 9, and reduced size 14 then is used to put binding post 3.One second hole 16 is passed between first hole, and is communicated with it.A multicore divides wiring can be placed in second hole, makes the corresponding heart yearn of branch wiring pass corresponding first hole.Therefore, when block 9 is placed on the binding post, its part 15 will contact corresponding heart yearn, at first pass the insulated hull of branch wiring in case of necessity.Second hole penetrates that preferably to reach the lateral dimension that such degree makes second hole in first hole just better less than 50% less than 67%() be positioned at first hole.Like this, two cores divide wiring to have only a heart yearn to fall in any one first hole, and can be contacted by the block in this first hole.

Adapter can have first hole more than two, and can have second hole more than.

Adapter can use together with device, for example anti-lightning strike device of protecting the circuit that is connected.This protective device can contain a terminal board, and this terminal board at first is placed on the binding post, and this terminal board has its oneself binding post to be placed on it by adapter again.This protective device can be with high-voltage earthing.

Fig. 3 illustrates a terminal board 2 of the present invention.This terminal board 2 can be regarded as and is similar to a series of binding post 3 adapters fixed thereon that have.Can see a first terminal plate hole 17 and pass between binding post 3, this hole 17 can hold a multicore and divide wiring to make its corresponding heart yearn near corresponding binding post.First hole does not reach first hole this situation of the height in terminal board passing the height that this formulation will comprise binding post between the binding post, and perhaps in other words, first hole is above the binding post top.In the case, block can have threaded portion down to be stretched under the parts that wiring engages with branch to contact with binding post.The situation of showing among the figure (just first hole is between the end face and bottom surface of each binding post) is recommended, and wherein binding post has the bolt form and blocks a shot and has the nut form.Have the bolt form if block a shot but binding post has the nut form, first Kongzui is arranged on the binding post end face well.Terminal board preferably has 2 to 25 pairs of posts, only illustrates a pair of among the figure.To can link on the binding post with any suitable method with the conductor of the multicore cable that divides wiring to connect, for example be soldered on the bottom of binding post with the soldering mode.

Fig. 4 is the plane graph of best adapter body 8 of the present invention, can see two parts 13,14 in first hole, also can see the passage in second hole 16 simultaneously.A multicore with two conductor core wires 19 is shown on the figure divides wiring 18 to prepare to slip into situation in the hole 16.The configuration of adapter body 8 is in order to provide a better fit on a terminal board time in that several such bodies are placed side by side in Fig. 4, and this situation is shown in Figure 5.

In Fig. 5 A, there are 5 adapter bodies 8 to be placed on 5 pairs of posts 3 of a terminal plate body seat 2.Among the figure left side illustrate adapter body 8 be with block a shot 9 in place.Divide wiring to extend in the adapter body, the body configuration is to be compact layout basically in order to allow, the lower left corner of body cuts to accept the branch wiring of adjacent body.Like this, first limit 20 of each adapter body has one and adds one with second limit 21 basically what stretch out from it is straight branch wiring shape similar shapes altogether basically.

The design class of Fig. 5 B is similar to Fig. 5 A, and still every pairs of posts is arranged along the size error of terminal board.This can leave the adapter that is placed on the terminal block along a direction perpendicular to the long limit of terminal block with regard to allowing the branch wiring, and the adapter that still can obtain a compactness is arranged.

Fig. 6 be one by having the phantom that a branch wiring 18 is inserted in it and is placed on the adapter part on terminal plate body seat 2 and the binding post 3.Can see that branch wiring 18 passes in hole 16 and from the back of left side binding post 3, like this, heart yearn 19A contacts with blocking a shot when binding post is backed out at block 9.So divide wiring 18 just to pass the cross section in the front of the binding post on the right side and near it, block just follows heart yearn 19B to contact on this binding post.

Can see block 9 internal threads that have with the threads engage of binding post 3.Block also has a part 15 that is stretched over top, first hole 13, the bottom of this part 15 to have the cutting edge 22 of incision insulated hull, and this cutting edge is cut the insulated hull of branch wiring to contact with its heart yearn.Cutting edge 22 is gone up by the bottom 13A that puts the wide upper portion 13 that leans against first hole and has been prevented that cutting edge from cutting off heart yearn.Block can have a kind of encapsulant such as gel, and preferably the form with necklace 23 occurs.

The adapter body can have a groove 24, can place the encapsulant such as gelinite in groove, also the form of necklace 25 preferably.When block was tightened on the binding post downwards, the adapter body was compressed against on the terminal plate body seat 2, thereby encapsulant is shifted round the surface of binding post, block and branch wiring.Encapsulant remains under the pressurized state by some measure, for example, tightens to elasticity on the binding post by control block.When block puts in place, can see that the heart yearn of branch wiring is connected with the binding post electricity, this binding post can be connected to again on the conductor of a multicore communication cable.Contact between block and the heart yearn can be maintained by some flexible biasing, the elastic biasing that pressurizes and produce by insulated hull for example to the branch wiring below heart yearn, or use additive method.

The multicore that adapter of the present invention and terminal board can be used for shelling skin divides wiring or paired single core to divide wiring.If needed, can provide some devices to divide binding clip to be held on the correct relative in two this single cores, for example provide some to fold up line or allow this that line is slipped into clamping device in it round this, like this, multicore divides wiring can be described as to be formed by single-core line.Wear twin-core and divide the same mode of wiring insulated hull to cut to wear this clamping device with cutting so the block of incision insulated hull is available.We recommend with folding up also and can be snapped together, make selectively the branch wiring to be cut into the clamping device of certain-length by two parts line round this.A clamping device 26 shown in Figure 7 was together with wiring in a pair of minute.Clamping device can have a hinges 28 and locking device 29, with lead 27 cut to the cutter sweep 30 of certain-length and the device 29 of positioning lead '.

Fig. 8 shows a novel terminal board 2 with negative thread binding post 31.Block 9 has the pin thread 32 that can be screwed in the binding post 31.Block also can have the cutting edge 22 of an incision insulated hull.Divide wiring 18 to enter in the hole 17 shown in the figure.The conductor of multicore cable 33 can be connected on the binding post 31 of terminal board 2 bottoms.Binding post 31 can flush with the bottom surface in hole 10, and in this case, screw thread 32 will be stretched under the cutting edge 22 of this block.Binding post 31 also is extensible on the bottom surface in hole 10, and in this case, screw thread 32 need not be stretched under the cutting edge 22.Divide wiring guiding or bracing or strutting arrangement 34 also on figure, to illustrate.

Fig. 9 A and Fig. 9 B show a phantom with the best block 9 of pin thread 32.Block has the cutting edge 22 and an encapsulant 23 of an incision insulated hull.Use the terminal board (or adapter) of this block need not dispose encapsulant, because block also provides if needed.Therefore, lost efficacy or the part loss, can use the new block that gives the good encapsulant of filling as encapsulant.Block can have device 35, and for example one is threaded or the gland of other structure, this gland can break-make external screw thread 32 and the cutting edge 22 of incision insulated hull between electrical connection.In the figure of Fig. 9 A, device 35 is partly removed, thereby has cut off the connection between screw thread 32 and the cutting edge 22, thereby has also cut off multicore cable and divided being connected between the wiring.In Fig. 9 B, device 35 is screwed to the position, thereby realize the electricity connection, this kind can break-make performance the different piece of the telephone circuit that adopts terminal board of the present invention is optionally tested is useful, also can unscrew block 9 a little and disconnect contact, the hole that device 35 only is configured to cover at this moment on the block, this hole can be used as a contact point of gauge head.

The adapter with the spacing between the first variable hole is showed in Figure 10～13.This adapter preferably has two first holes, but more first hole also can be arranged.

Figure 10 shows an adapter that is in the form of taking apart, and this adapter contains a body 8, and this body has two parts, and the first parts 8A is on the left side of figure and the second parts 8B right side at figure.The first parts 8A is passed in one first hole 10 and the second parts 8B is passed in one second first hole 10.Each the first and second parts 8A, 8B have a base 36 and a branch binding clip is held seat 37.The branch binding clip that a part 16A in second hole is positioned at the first parts 8A is held seat 37 and another part 16B is positioned at the branch binding clip of the second parts 8B and holds 37.Common second hole can be stretched and be passed a branch binding clip and hold seat, another minute binding clip hold and then become a blind hole in the seat.Second Kongzui is non-circular well, and generally preferably rectangle or long round section divide wiring 18 relevantly to hold a multicore.The base of first parts can be not continuous with the base of second parts, but we recommend two bases to connect together, and for example connect together slidably.A kind of method of being slidingly connected is that the first and second parts telescopicallies are connected, and for example, inserts in the hole of another base being contained in pin 38 telescopicallies on the base.A base (or being referred to as parts) causes two first spacings between the hole 10 to change with respect to slip or other motion of another base.Therefore, a kind of given adapter can be used in the design of the terminal board with the spacing between different binding posts.

When base 36 shifts near mutually or removes, in general, divide binding clip to hold that seat 37 must can rotate and preferably a pair of each can both be done the angle around the axis in separately first hole and rotates and do not make an orbit rotation around another.This rotation preferably can allow the part 16A in second hole and another part 16B still keep in line, because the convenient like this insertion that divides wiring 18.Divide binding clip to hold the protuberance 35 that seat 37 can have a circle in its lower end, allow the branch binding clip hold seat and be assemblied in rotationally in the surface of base.

This slip of base 36 will cause the 16A part to be separated with the 16B parts transversely with this rotation that divides binding clip to hold seat.Because the spacing variable quantity of binding post can not be very big, in second hole, divide the fit-up gap of wiring can be enough to allow the branch wiring be inserted.

Figure 11 A illustrates separating of base 36 with Figure 11 B and divides binding clip to hold the effect of the rotation of seat 37.

Figure 12 illustrates a kind of modification of the design of Figure 10 and Figure 11, and wherein, the first and second parts 8A, 8B are assembled together slidably mutually, and glide direction is arranged essentially parallel to the 16A part in second hole and the straight line that the 16B part is provided with along it basically.Pin 38 or other device generally are to be parallel to 16A part and 16B part by desired direction setting.

The adapter of Figure 13 has one first parts 8A and one second parts 8B, and each parts can be overall structure or be made up of two or more parts that preferably are immovably fixed together.

Each parts has one first hole 10, and this first hole 10 has a larger-diameter top 13(who is used to accept a block as shown) and a binding post penetrate lower part 14 in it than minor diameter.The first and second parts 8A, 8B can interconnect with a flexible connector 40.This connector can be a metal line or rope or multi cord or a kind of thin slice of material.

This connector 40 can adhere on the surface of parts 8A, 8B, but also in insertion parts groove, or also can be in aggregates with each parts.If necessary, connector can be adjusted, and makes the spacing between parts 8A and the 8B can be changed, at least temporarily be fixed on the new distance values then.
