Abstract
The present invention relates to a kind of connector for low energy fuse.Comprise a fuel plate, this fuel plate has 2 substantially parallel surfaces and at least a sides are sealed, and has at least four passages to enter this element from one or each side, and each passage is interconnected in inside.Can wash ripple off with one by this connector for low energy fuse and pass to the secondary detonator of multistage from one section elementary detonator.
Description
The present invention relates to a connector for low energy fuse, a shock wave can be passed to the secondary detonator of multistage from one section elementary detonator whereby.
In this manual, " low energy fuse " speech refers to one section plastic flexible pipe, scribbles explosive substance or pyrotechnics coating at least in flexible pipe inside.This low energy fuse is also referred to as the low energy impact pipe usually." shock wave " speech both can be regarded as a shock front of propagating in addition, also can be understood as the detonation face of propagation.
The invention provides a connector for low energy fuse, it comprises a fuel plate, this fuel plate has two substantially parallel surfaces and has a side at least is sealing surface, have at least four passages to enter this element from one of element or each side, respectively this passage is communicated with each other in inside.
This element can be cube, and its surface is straight.Therefore, this element can have 4 sides, and wherein two relative faces are parallel to each other, and other two faces also are parallel to each other.Therefore, at least one passage can enter this element from a side and another passage enters this element from its opposite.At least another passage can protrude into this element from an adjacent surface equally.If have passage to enter on relative face, they preferably stagger each other.
Passage preferably roughly is straight.Each passage can be in the same plane haply.In addition, a passage can be used as access road, and access road can be in the central authorities of this element, and other passages can be used as exit passageway, and exit passageway is in its both sides.
This passage can inwardly be tapered so that clamp the detonator that inserts wherein.And, in passage, can provide a kind of clamping device in order from a passage, to deviate from the end that prevents detonator.In preferable structure, channel interior all is step-like or has the insertable scope of " eck " part with restriction detonator end.
This element can also have a fixture.Whereby, can be fixed on one section detonator on this element.In a kind of structure, this fixture can be the eyelet in the element, and by it, detonator can be fixing around a circle, therefore detonator was pulled, and passage can not deviate from easily in its end yet.
The professional who is familiar with in the art knows, uses when different occasion, and the number of used detonator can be different, and not necessarily all outlets are all used.Therefore,, exist, problem will take place, mistake because such shock wave will escape if that is to say the passage that oriented ambient atmosphere opens wide if not every outlet is all used.Therefore, provide a kind of locking device that is used for sealing outlet (if necessary, import too).This locking device can be one group of stopple that is used for the closed channel mouth, also can be to be positioned at passway or the inner film that can poke.In a kind of structure, this film that can poke is enclosed in the film on those sides of open channel.
This element can be to be processed into by method of molding with moldable material.This element also can be made by synthetic plastics material.
With reference to the accompanying drawings, present invention is described by an example, wherein:
Fig. 1 is the stereogram according to connector of the present invention; With
Fig. 2 is the profile of the connector of Fig. 1.
Referring to accompanying drawing.What connector was total in the drawings represents with coding 10.It comprises an element 12, and synthetic plastics material that these element 12 usefulness are suitable such as polypropylene or Merlon are made.Connector 10 is (not shown)s made from suitable mould.
As shown in Figure 1, element 12 is tabular, rectangle and substantially flat.The length and the stand out of element 12 are few, and thickness is then much smaller than length and width.Element 12 has an end face 14 and two sides 16 and 18.In addition, element 12 has an intake channel 20 and 4 exit passageways 22 and 24, and they all are straight passages, as we can see from the figure, exit passageway 22 and 24 is with respect to intake channel 20 horizontal expansions, and exit passageway 22 is in a side of intake channel 20, and 24 of exit passageways are at opposite side.In addition, passage 20,22 and 24 is coplanar, and exit passageway 24 intersects with intake channel 20 like this.Exit passageway 22 on a side 16 to the outside and exit passageway 24 on another side 18, lead to the outside.All has sawtooth 26 near passage 20,22 and 24 the inlet, to clamp insertion low energy fuse wherein.Perhaps, passage can inwardly be tapered.Be appreciated that exit passageway 22 and 24 keeps being communicated with intake channel 20.What should also be noted that is that passage 20,22 and 24 all has a step 28 inserts passage with the restriction detonator scope.Be appreciated that like this, the contact between intake channel 20 and the exit passageway 22,24 will be blocked if low energy fuse can directly be inserted into the terminal 30 of intake channel 20 maybe can extend in the intake channel 20 by exit passageway 22 or 24 always.
The professional who is familiar with the present technique field is appreciated that element 12, except rectangular, can also be any other suitable shape.
Be covered with a film 32 on the side 14,16 and 18, this film can be poked by low energy fuse, and like this, passage 20,22 and 24 keeps sealing before use always, and obsolete passage continues to keep sealing.
Perforation 34 on the element 12, like this, in use, can pass eyelet 34 earlier and then passage be inserted in their end around a circle, and it is minimum that the possibility that makes detonator be pulled out element 12 so just reduces to.
During use, one section elementary detonator (not shown) is inserted stand in channel 20 by an eyelet 34 then around a circle, pokes the film on the inlet of access road 20.The end of two sections or the secondary detonator of multistage is also passed eyelet 34 earlier and is inserted different exit passageways 22 and/or 24 around a circle back, and in this course, pokes the film on these passages.Like this, the shock wave in elementary detonator just can and enter into exit passageway 22 and 24 along intake channel 20 propagation, inspires bow wave in secondary detonator.
By the present invention, provide a kind of cheapness and reliable connector so that a plurality of secondary detonators are connected on the elementary detonator.
